In this project, an Excel based automated tool has been developed which extensively uses D3.Js, R, Excel VBA and Phantom JS to provide an integrated application that automatically fetches the data from the web and develops models, creates interactive hovering data label D3 charts on excel and also tests the accuracy of the predictions just at the click of a button. Though the models are very basic, the automation mechanism is effective and can be used by people who still want to rely on basic excel apps for stock data analytics.

Internet of Things (IoT) is one of the most disruptive technologies now- adays which can efficiently connect, control and manage intelligent objects those are connected to the Internet. IoT based applications like smart education, smart agriculture, smart health-care, smart homes etc which can deliver services with- out manual intervention and in a more effective manner. In this work, we have proposed a IoT based smart home automation system using a micro-controller based Arduino board and mobile based Short Message service (SMS) application working functionality. Wi connectivity has been used to establish the communi- cation between the Arduino module and automated home appliances. We have proposed a real-time scheduling strategy that offers a novel communication pro- tocol to control the home environment with the switching functionality. Our sim- ulation results show that the proposed strategy is quite capable to achieve high performance with different simulation scenarios.

Logopolitan computers could also be integrated in Cyber-Neural fusion to advance our brains, allowing them to interpret quantum code and convert it into computer code, and that code into Neural data, creating humans of immeasurable IQ and mental capabilities. While this area isn't quite the place for positing the philosophies of what this would mean, one could imagine what we could do if we simply accepted this tech and put in the resources to achieve it.

The power of the method Bayati and his colleagues outline is that it can be used to pursue multiple goals at once. [37] Using micromagnetic simulation, scientists have found the magnetic parameters and operating modes for the experimental implementation of a fast racetrack memory module that runs on spin current, carrying information via skyrmionium, which can store more data and read it out faster. [36] Scientists at the RDECOM Research Laboratory, the Army's corporate research laboratory (ARL) have found a novel way to safeguard quantum information during transmission, opening the door for more secure and reliable communication for warfighters on the battlefield. [35] Encrypted quantum keys have been sent across a record-breaking 421 km of optical fibre at the fastest data rate ever achieved for long-distance transmission. [34] The companies constructed an application for data transmission via optical fiber lines, which when combined with high-speed quantum cryptography communications technologies demonstrated practical key distribution speeds even in a real-world environment. [33] Nanosized magnetic particles called skyrmions are considered highly promising candidates for new data storage and information technologies. [32] They do this by using "excitons," electrically neutral quasiparticles that exist in insulators, semiconductors and in some liquids. [31] Researchers at ETH Zurich have now developed a method that makes it possible to couple such a spin qubit strongly to microwave photons. [30] Quantum dots that emit entangled photon pairs on demand could be used in quantum communication networks. [29] Researchers successfully integrated the systems—donor atoms and quantum dots. [28] A team of researchers including U of A engineering and physics faculty has developed a new method of detecting single photons, or light particles, using quantum dots. [27] Recent research from Kumamoto University in Japan has revealed that polyoxometalates (POMs), typically used for catalysis, electrochemistry, and photochemistry, may also be used in a technique for analyzing quantum dot (QD) photoluminescence (PL) emission mechanisms.

The Pentagon on Friday said there has been a cyber breach of Defense Department travel records that compromised the personal information and credit card data of U.S. military and civilian personnel. [41] Quantum secure direct communication transmits secret information directly without encryption. [40] Physicists at The City College of New York have used atomically thin two-dimensional materials to realize an array of quantum emitters operating at room temperature that can be integrated into next generation quantum communication systems. [39] Research in the quantum optics lab of Prof. Barak Dayan in the Weizmann Institute of Science may be bringing the development of such computers one step closer by providing the "quantum gates" that are required for communication within and between such quantum computers. [38] Calculations of a quantum system's behavior can spiral out of control when they involve more than a handful of particles. [37] Researchers from the University of North Carolina at Chapel Hill have reached a new milestone on the way to optical computing, or the use of light instead of electricity for computing. [36] The key technical novelty of this work is the creation of semantic embeddings out of structured event data. [35] The researchers have focussed on a complex quantum property known as entanglement, which is a vital ingredient in the quest to protect sensitive data. [34] Cryptography is a science of data encryption providing its confidentiality and integrity. [33] Researchers at the University of Sheffield have solved a key puzzle in quantum physics that could help to make data transfer totally secure. [32]

I have been working for a time about basic laws of directing the universe [1,2]. It seems that the most basic and impressive principle which causes any physical phenomenon is the Uncertainty Principle of Heisenberg [3], that existence have any property because of the uncertainty. During this process, while I was thinking about conservation of information I noticed, that information cannot be lost; but at a point, it becomes completely unrecognizable according to us as there is no alternative. Any information and the information searched for become the same after a point relatively to us. The sensitivity increases forever but its loss. Each sensitivity level also has higher level; so actually an absolute protection seems possible.

Workflow management systems allow users to prepare, produce and analyze scientific processes to help simplify complex simulations. [27] Now, a team of A*STAR researchers and colleagues has developed a detector that can successfully pick out where human actions will occur in videos, in almost real-time. [26] A team of researchers affiliated with several institutions in Germany and the U.S. has developed a deep learning algorithm that can be used for motion capture of animals of any kind. [25] In 2016, when we inaugurated our new IBM Research lab in Johannesburg, we took on this challenge and are reporting our first promising results at Health Day at the KDD Data Science Conference in London this month. [24] The research group took advantage of a system at SLAC's Stanford Synchrotron Radiation Lightsource (SSRL) that combines machine learning—a form of artificial intelligence where computer algorithms glean knowledge from enormous amounts of data—with experiments that quickly make and screen hundreds of sample materials at a time. [23] Researchers at the UCLA Samueli School of Engineering have demonstrated that deep learning, a powerful form of artificial intelligence, can discern and enhance microscopic details in photos taken by smartphones. [22] Such are the big questions behind one of the new projects underway at the MIT-IBM Watson AI Laboratory, a collaboration for research on the frontiers of artificial intelligence. [21] The possibility of cognitive nuclear-spin processing came to Fisher in part through studies performed in the 1980s that reported a remarkable lithium isotope dependence on the behavior of mother rats. [20] And as will be presented today at the 25th annual meeting of the Cognitive Neuroscience Society (CNS), cognitive neuroscientists increasingly are using those emerging artificial networks to enhance their understanding of one of the most elusive intelligence systems, the human brain. [19] U.S. Army Research Laboratory scientists have discovered a way to leverage emerging brain-like computer architectures for an age-old number-theoretic problem known as integer factorization.

We develop two different polynomial-time integer factorization algorithms.
We reduce integer factorization problem to equivalent problem of minimizing
a quadratic polynomial with integer coefficients over the integer points
in a quadratically constrained two-dimensional region.
Next, we reduce those minimization problem to the polynomial-time minimizing
a quadratic polynomial with integer coefficients over the integer
points in a special two-dimensional rational polyhedron.
Next, we reduce integer factorization problem to the problem of enumeration
of vertices of integer hull of a special two-dimensional rational polyhedron,
solvable in time polynomial by Hartmann's algorithm.
Finally, as we show that there exists an NP-hard minimization problem,
equivalent to the original minimization problem, we conclude that P = NP.

This preliminary note presents a heuristic for determining rank constrained solutions to
linear matrix equations (LME). The method proposed here is based on minimizing a non-
convex quadratic functional, which will hence-forth be termed as the Low-Rank-Functional
(LRF). Although this method lacks a formal proof/comprehensive analysis, for example in
terms of a probabilistic guarantee for converging to a solution, the proposed idea is intuitive
and has been seen to perform well in simulations. To that end, many numerical examples are
provided to corroborate the idea.

Historically as well as mathematically, the octonions were derived from the quaternions, and the quaternions from the complex numbers. A proper C++ implementation of these numerical types should reflect these relationships.

BITCONCH chain proposed an innovative POR (Proof Of Reputation) reputation consensus algorithm, which solved the pain point that the blockchain is difficult to maintain both high throughput and decentralization. Based on social graphs, BITCONCH Chain mathematically models social, time, and contribution activities to build a decentralized reputation system. Each user has the opportunity to establish a high reputation value. The higher the user's reputation, the lower the transaction cost (or even free). The more opportunities that are selected as trust nodes to participate in the consensus, the greater the benefits. High-reputation users are defined as “mutual trust nodes”, and small micro-transactions will start “payment channels” for high-speed offline transactions.
The reputation system and system incentive system will effectively promote the continued enthusiasm of business developers and ordinary users, and contribute to the construction of the business ecosystem. Business developers with traffic are more likely to get high reputation values, and the chances of being elected to a trusted full node are higher. Ordinary users can increase reputation by actively engaging in social interactions and actively using business applications in the ecosystem, increasing the chances of being selected as trusted light nodes.
The Bitconch chain uses a DAG directed acyclic graph data structure to maintain the system's positive scalability. Support smartphone light node client to resist the decentralization of the system and maintain dispersion. Zero-knowledge verification, latticed data storage, quantum-level encryption algorithms, and improved BVM virtual machines make Bitconch chain more reliable and provide a friendly DApp and sidechain development environment to meet certain applications. Technical requirements for large file storage, low transaction costs, user information protection, sidechain and smart contract iterations, and bug fixes.
BITCONCH chain is a decentralized distributed network with no block and no chain, which solves two difficulties in the application of blockchain: scalability and decentralization. Bitconch chain, which can be applied to the commercial application needs of users above 10 million, is the most feasible blockchain ecosystem for high-frequency small micro-transactions and social applications.

Cryptography is a science of data encryption providing its confidentiality and integrity. [33] Researchers at the University of Sheffield have solved a key puzzle in quantum physics that could help to make data transfer totally secure. [32] "The realization of such all-optical single-photon devices will be a large step towards deterministic multi-mode entanglement generation as well as high-fidelity photonic quantum gates that are crucial for all-optical quantum information processing," says Tanji-Suzuki. [31] Researchers at ETH have now used attosecond laser pulses to measure the time evolution of this effect in molecules. [30] A new benchmark quantum chemical calculation of C2, Si2, and their hydrides reveals a qualitative difference in the topologies of core electron orbitals of organic molecules and their silicon analogues. [29] A University of Central Florida team has designed a nanostructured optical sensor that for the first time can efficiently detect molecular chirality—a property of molecular spatial twist that defines its biochemical properties. [28] UCLA scientists and engineers have developed a new process for assembling semiconductor devices. [27] A new experiment that tests the limit of how large an object can be before it ceases to behave quantum mechanically has been proposed by physicists in the UK and India. [26] Phonons are discrete units of vibrational energy predicted by quantum mechanics that correspond to collective oscillations of atoms inside a molecule or a crystal. [25] This achievement is considered as an important landmark for the realization of practical application of photon upconversion technology. [24]

Tal como ocorre com o método simplex, que pode resolver em tempo polinomial a grande maioria dos problemas de programação linear, também é possível resolver SAT em tempo polinomial na maioria das vezes, que é o que eu mostro neste trabalho.

We propose the Non-negative Quadratic Pursuit (NQP) algorithm to approximately minimize a quadratic function in the presence of the $l0$-norm constraint. It is a quadratic generalization of matching pursuit method which is reformulated in a non-negative framework. Although the optimization problem is NP-hard, NQP provides an approximate solution to the problem which is locally optimal, but acceptable in the general literature.
In this document, we explain the algorithm's exact steps along with its convergence proof and complexity analysis.

SOA (Service Oriented Architecture) and micro SOA (Micro Service) have the advantages of high cohesion and low coupling, but at the same time they also bring complicated implementation, maintenance, high network load, and weak consistency. At the same time, they also increase product development and operation costs. This article attempts to use an improved approach by a kind of plug-in isolation mechanism that avoids the above issues as much as possible while preserving the benefits of SOA.
In addition, this paper also proposes a new strong consistent distributed coordination algorithm for improving the low performance and high overhead (at least three network broadcasts and multiple disk I/O requests per request) problem of existing Paxos/Raft algorithms. This algorithm, at the expense of data reliability, completely eliminates the above overhead and provides the same level of strong agreement and high availability guarantees as the Paxos/Raft algorithm.

In recent years, with the rapid development of cloud computing and IoT, the demand for big data has increased and the need for large data center and enterprise data center has been actively promoted. (1,3)
In this paper, a system design method that integrates and manages various information systems in the data centers of enterprise units is dealt with.
Since the production facilities of medium-scale units are managed by various detention facilities and control devices, an integrated monitoring system should be established to manage them collectively. (2)
Therefore, the paper suggests a standard design for proposing an integrated model face-to-face configuration of various facilities to be managed in enterprise units and an integrated monitoring system for environmental facilities, do.
And we try to evaluate the effectiveness of the system by analyzing the failure information transmission time of the integrated monitoring system.

In the field of business services, we also need to improve the size and service quality of our web apps, and
Ajax technology is constantly expanding.(5)
In the fields of stocks, finance, auctions, etc. that deal with large-scale, real-time data, it is important for
business service providers to transmit information to users as soon as possible.
This Paper describes one way of using Ajax components to realize asynchronous communication of Web
service providers on the Internet.
Ajax components consist of an Ajax core that supports Epoll and an Ajax library that supports asynchronous communication, and provides an application interface to define and implement various push functions.(2)Web service applications developed using Ajax components can provide various push services by using
asynchronous communication with client by using Epoll method.

Scientists at the Max Planck Institute for Brain Research in Frankfurt have now shown how the new model can be used to investigate multiple properties in parallel. [28] Scientists at the Department of Energy's Oak Ridge National Laboratory are conducting fundamental physics research that will lead to more control over mercurial quantum systems and materials. [27] Physicists in Italy have designed a " quantum battery " that they say could be built using today's solid-state technology. [26] Researches of scientists from South Ural State University are implemented within this area. [25] Following three years of extensive research, Hebrew University of Jerusalem (HU) physicist Dr. Uriel Levy and his team have created technology that will enable computers and all optic communication devices to run 100 times faster through terahertz microchips. [24] When the energy efficiency of electronics poses a challenge, magnetic materials may have a solution. [23] An exotic state of matter that is dazzling scientists with its electrical properties, can also exhibit unusual optical properties, as shown in a theoretical study by researchers at A*STAR. [22] The breakthrough was made in the lab of Andrea Alù, director of the ASRC's Photonics Initiative. Alù and his colleagues from The City College of New York, University of Texas at Austin and Tel Aviv University were inspired by the seminal work of three British researchers who won the 2016 Noble Prize in Physics for their work, which teased out that particular properties of matter (such as electrical conductivity) can be preserved in certain materials despite continuous changes in the matter's form or shape. [21] Researchers at the University of Illinois at Urbana-Champaign have developed a new technology for switching heat flows 'on' or 'off'. [20] Thermoelectric materials can use thermal differences to generate electricity. Now there is an inexpensive and environmentally friendly way of producing them with the simplest tools: a pencil, photocopy paper, and conductive paint. [19] A team of researchers with the University of California and SRI International has developed a new type of cooling device that is both portable and efficient. [18]

We reduce integer factorization problem to the equivalent problem of minimizing
a quadratic polynomial with integer coefficients over the integer
points in a quadratically constrained two-dimensional region.
Next, we reduce integer factorization problem to the problem of enumeration
of vertices of integer hull of a special two-dimensional rational polyhedron,
solvable in time polynomial by Hartmann's algorithm.
Finally, as we show that there exists an NP-hard minimization problem,
equivalent to the original minimization problem, we conclude that P = NP.

Abstract-Task scheduling is one of the most challenging aspects in cloud computing nowadays,
which plays an important role to improve the overall performance and services of the cloud such
as response time, cost, makespan, throughput etc. Recently, a cloud task scheduling algorithm
based on the Symbiotic Organisms Search (SOS) not only have fewer specific parameters, but also
take a little time complexity. Symbiotic Organism Search (SOS) is a newly developed metaheuristic
optimization technique for solving numerical optimization problems. In this paper, the basic
SOS algorithm is reduced and a chaotic local search(CLS) is integrated into the reduced SOS to
improve the convergence rate of the basic SOS algorithm. Also, Simulated Annealing (SA) is
combined in order to asist the SOS in avoiding being trapped into local minimum. The performance
of the proposed SA-CLS-SOS algorithm is evaluated by extensive simulation using MATLAB simulation
framework and compared with SOS, SA-SOS and CLS-SOS. Results of simulation showed that improved
hybrid SOS performs better than SOS, SA-SOS and CLS-SOS in terms of convergence speed and makespan
time.

Researchers have discovered that input-output maps, which are widely used throughout science and engineering to model systems ranging from physics to finance, are strongly biased toward producing simple outputs. [38] A QEG team has provided unprecedented visibility into the spread of information in large quantum mechanical systems, via a novel measurement methodology and metric described in a new article in Physics Review Letters. [37] Researchers from Würzburg and London have succeeded in controlling the coupling of light and matter at room temperature. [36] Researchers have, for the first time, integrated two technologies widely used in applications such as optical communications, bio-imaging and Light Detection and Ranging (LIDAR) systems that scan the surroundings of self-driving cars and trucks. [35] The unique platform, which is referred as a 4-D microscope, combines the sensitivity and high time-resolution of phase imaging with the specificity and high spatial resolution of fluorescence microscopy. [34] The experiment relied on a soliton frequency comb generated in a chip-based optical microresonator made from silicon nitride. [33] This scientific achievement toward more precise control and monitoring of light is highly interesting for miniaturizing optical devices for sensing and signal processing. [32] It may seem like such optical behavior would require bending the rules of physics, but in fact, scientists at MIT, Harvard University, and elsewhere have now demonstrated that photons can indeed be made to interact-an accomplishment that could open a path toward using photons in quantum computing, if not in light sabers. [31] Optical highways for light are at the heart of modern communications. But when it comes to guiding individual blips of light called photons, reliable transit is far less common. [30] Theoretical physicists propose to use negative interference to control heat flow in quantum devices. [29] Particle physicists are studying ways to harness the power of the quantum realm to further their research. [28]

As cloud storage becomes more common, data security is an increasing concern. [34] Scientists of the National Research Nuclear University MEPhI (Russia) have proposed a scheme for optical encoding of information based on the formation of wave fronts, and which works with spatially incoherent illumination. [33] A joint China-Austria team has performed quantum key distribution between the quantum-science satellite Micius and multiple ground stations located in Xinglong (near Beijing), Nanshan (near Urumqi), and Graz (near Vienna). [32] In the race to build a computer that mimics the massive computational power of the human brain, researchers are increasingly turning to memristors, which can vary their electrical resistance based on the memory of past activity. [31] Engineers worldwide have been developing alternative ways to provide greater memory storage capacity on even smaller computer chips. Previous research into two-dimensional atomic sheets for memory storage has failed to uncover their potential— until now. [30] Scientists used spiraling X-rays at the Lab) to observe, for the first time, a property that gives handedness to swirling electric patterns – dubbed polar vortices – in a synthetically layered material. [28] To build tomorrow's quantum computers, some researchers are turning to dark excitons, which are bound pairs of an electron and the absence of an electron called a hole. [27] Concerning the development of quantum memories for the realization of global quantum networks, scientists of the Quantum Dynamics Division led by Professor Gerhard Rempe at the Max Planck Institute of Quantum Optics (MPQ) have now achieved a major breakthrough: they demonstrated the long-lived storage of a photonic qubit on a single atom trapped in an optical resonator. [26] Achieving strong light-matter interaction at the quantum level has always been a central task in quantum physics since the emergence of quantum information and quantum control. [25]

Behind every self-driving car, self-learning robot and smart building hides a variety of advanced algorithms that control learning and decision making. [17] Quantum computers can be made to utilize effects such as quantum coherence and entanglement to accelerate machine learning. [16] Neural networks learn how to carry out certain tasks by analyzing large amounts of data displayed to them. [15] Who is the better experimentalist, a human or a robot? When it comes to exploring synthetic and crystallization conditions for inorganic gigantic molecules, actively learning machines are clearly ahead, as demonstrated by British Scientists in an experiment with polyoxometalates published in the journal Angewandte Chemie. [14] Machine learning algorithms are designed to improve as they encounter more data, making them a versatile technology for understanding large sets of photos such as those accessible from Google Images. Elizabeth Holm, professor of materials science and engineering at Carnegie Mellon University, is leveraging this technology to better understand the enormous number of research images accumulated in the field of materials science. [13] With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. [12] The artificial intelligence system's ability to set itself up quickly every morning and compensate for any overnight fluctuations would make this fragile technology much more useful for field measurements, said co-lead researcher Dr Michael Hush from UNSW ADFA. [11] Quantum physicist Mario Krenn and his colleagues in the group of Anton Zeilinger from the Faculty of Physics at the University of Vienna and the Austrian Academy of Sciences have developed an algorithm which designs new useful quantum experiments. As the computer does not rely on human intuition, it finds novel unfamiliar solutions. [10] Researchers at the University of Chicago's Institute for Molecular Engineering and the University of Konstanz have demonstrated the ability to generate a quantum logic operation, or rotation of the qubit, that-surprisingly—is intrinsically resilient to noise as well as to variations in the strength or duration of the control. Their achievement is based on a geometric concept known as the Berry phase and is implemented through entirely optical means within a single electronic spin in diamond. [9]

Kalman Folding 5 presents an Extended Kalman Filter in Mathematica. Python is much more accessible to average practitioners. In this follow-up article, we write a very general, foldable EKF in Python, verify it against Mathematica using sympy, Python's package for symbolic mathematics. We apply it to a spinning dashpot and demonstrate both state estimation and system identification from observing only one angle over time. It is remarkable that a complete dynamical description of eight states and parameters can be recovered from measurements of a single, scalar value.

We investigate a new threat: networks of stealthy
routers (S-Routers), communicating across a restricted area. The ‘classical’ approach of transmission-detection by triangulation fails, since S-Routers use short-range, low-energy communication, detectable only by nearby devices.
We investigate algorithms to intercept S-Routers, using one or more mobile devices, called Interceptors. Given a source of
communication, Interceptors find the destination, by intercepting packet-relaying by S-Routers along the path. We evaluate the algorithms analytically and experimentally (simulations), including against a parametric, optimized S-Routers algorithm. Our main result is a (centralized) Interceptors algorithm bounding the outcome to O(Nlog^2(N), where N is the number of S-Routers. We later improve the bound to O(Nlog(N)log(log(N))), for the case where the transmission schedule of the S-Routers is continuous.

Due to the increasing demand for cloud services and the threat of privacy invasion, the user is suggested to encrypt the data before it is outsourced to the remote server. The safe storage and efficient retrieval of d-dimensional data on an untrusted server has therefore crucial importance. The paper proposes a new encryption model which offers spatial order-preservation for d-dimensional data (SOPE model). The paper studies the operations for the construction of the encrypted database and suggests algorithms that exploit unique properties that this new model offers for the efficient execution of a whole range of well-known queries over the encrypted d-dimensional data. The new model utilizes wellknown database indices, such as the B+-tree and the R-tree, as backbone structures in their traditional form, as it suggests no modifications to them for loading the data and for the efficient execution of the supporting query algorithms. An extensive experimental study that is also presented in the paper indicates the effectiveness and practicability of the proposed encryption model for real-life d-dimensional data applications.

While technologies that currently run on classical computers, such as Watson, can help find patterns and insights buried in vast amounts of existing data, quantum computers will deliver solutions to important problems where patterns cannot be seen because the data doesn't exist and the possibilities that you need to explore to get to the answer are too enormous to ever be processed by classical computers.

Through a collaboration between the University of Calgary, The City of Calgary and researchers in the United States, a group of physicists led by Wolfgang Tittel, professor in the Department of Physics and Astronomy at the University of Calgary have successfully demonstrated teleportation of a photon (an elementary particle of light) over a straight-line distance of six kilometers using The City of Calgary's fiber optic cable infrastructure. [15]
Optical quantum technologies are based on the interactions of atoms and photons at the single-particle level, and so require sources of single photons that are highly indistinguishable – that is, as identical as possible. Current single-photon sources using semiconductor quantum dots inserted into photonic structures produce photons that are ultrabright but have limited indistinguishability due to charge noise, which results in a fluctuating electric field.

The authors have recently shown that recognizing low fractional hypertree-width (fhw) is NP-complete
in the general case and that the problem becomes tractable if the hypergraphs under consideration have degree and intersection width bounded by a constant, i.e., every vertex is contained in only constantly many different edges and the intersection of two edges contains only constantly many vertices. In this article, we show that bounded degree alone suffices to ensure tractability.

Concepts for information storage and logical processing based on magnetic domain walls have great potential for implementation in future information and communications technologies." [21] Research at the National Institute of Standards and Technology (NIST) suggests it also may be true in the microscopic world of computer memory, where a team of scientists may have found that subtlety solves some of the issues with a novel memory switch. [20] Los Alamos National Laboratory has produced the first known material capable of single-photon emission at room temperature and at telecommunications wavelengths. [19] In their paper published in Nature, the team demonstrates that photons can become an accessible and powerful quantum resource when generated in the form of colour-entangled quDits. [18] But in the latest issue of Physical Review Letters, MIT researchers describe a new technique for enabling photon-photon interactions at room temperature, using a silicon crystal with distinctive patterns etched into it. [17] Kater Murch's group at Washington University in St. Louis has been exploring these questions with an artificial atom called a qubit. [16] Researchers have studied how light can be used to observe the quantum nature of an electronic material. [15] An international team of researchers led by the National Physical Laboratory (NPL) and the University of Bern has revealed a new way to tune the functionality of next-generation molecular electronic devices using graphene.

This theory is useful for future quantum technologies.

Over millennia, nature has evolved an incredible information storage medium – DNA. It evolved to store genetic information, blueprints for building proteins, but DNA can be used for many more purposes than just that. [23] Based on early research involving the storage of movies and documents in DNA, Microsoft is developing an apparatus that uses biology to replace tape drives, researchers at the company say. [22] Our brains are often compared to computers, but in truth, the billions of cells in our bodies may be a better analogy. The squishy sacks of goop may seem a far cry from rigid chips and bundled wires, but cells are experts at taking inputs, running them through a complicated series of logic gates and producing the desired programmed output. [21] At Caltech, a group of researchers led by Assistant Professor of Bioengineering Lulu Qian is working to create circuits using not the usual silicon transistors but strands of DNA. [20] Researchers have introduced a new type of "super-resolution" microscopy and used it to discover the precise walking mechanism behind tiny structures made of DNA that could find biomedical and industrial applications. [19] Genes tell cells what to do—for example, when to repair DNA mistakes or when to die—and can be turned on or off like a light switch. Knowing which genes are switched on, or expressed, is important for the treatment and monitoring of disease. Now, for the first time, Caltech scientists have developed a simple way to visualize gene expression in cells deep inside the body using a common imaging technology.

In this paper, we propose a two-phase Content-Based Retrieval System for images embedded in the Neutrosophic domain. In this first phase, we extract a set of features to represent the content of each image in the training database. In the second phase, a similarity measurement is used to determine the distance between the image under consideration (query image), and each image in the training database, using their feature vectors constructed in the first phase. Hence, the N most similar images are retrieved.

In the quest to make computers faster and more efficient, researchers have been exploring the field of spintronics—shorthand for spin electronics—in hopes of controlling the natural spin of the electron to the benefit of electronic devices. [27]
When two researchers from the Swiss Federal Institute of Technology (ETH Zurich) announced in April that they had successfully simulated a 45-qubit quantum circuit, the science community took notice: it was the largest ever simulation of a quantum computer, and another step closer to simulating "quantum supremacy"—the point at which quantum computers become more powerful than ordinary computers.

We utilize a previously reported methodological framework [5], to find a general set of mappings for any satisfiability (SAT) problem to a set of arithmetized codes allowing a classification hierarchy enumerable via integer partition functions. This reveals a unique unsatisfiability criterion via the introduction of certain universal indicator functions associating the validity of any such problem with a mapping between Mersenne integers and their complements in an inclusive hierarchy of exponential intervals. Lastly, we present means to reduce the complexity of the original problem to that of a special set of binary sequences and their bit block analysis via a reduction of any expression to a type of a Sequential Dynamical System (SDS) using the technique of clause equalization. We specifically notice the apparent analogy of certain dynamical properties behind such problems with resonances and coherencies of multi-periodic systems leading to the possibility of certain fast analog or natural implementations of dedicated SAT-machines. A Matlab toolbox is also offered as additional aid in exploring certain simple examples.

Chemists at Case Western Reserve University have found a way to possibly store digital data in half the space current systems require. [12] Using lasers to make data storage faster than ever. [11] Some three-dimensional materials can exhibit exotic properties that only exist in "lower" dimensions. For example, in one-dimensional chains of atoms that emerge within a bulk sample, electrons can separate into three distinct entities, each carrying information about just one aspect of the electron's identity—spin, charge, or orbit. The spinon, the entity that carries information about electron spin, has been known to control magnetism in certain insulating materials whose electron spins can point in any direction and easily flip direction. Now, a new study just published in Science reveals that spinons are also present in a metallic material in which the orbital movement of electrons around the atomic nucleus is the driving force behind the material's strong magnetism. [10] Currently studying entanglement in condensed matter systems is of great interest. This interest stems from the fact that some behaviors of such systems can only be explained with the aid of entanglement. [9] Researchers from the Norwegian University of Science and Technology (NTNU) and the University of Cambridge in the UK have demonstrated that it is possible to directly generate an electric current in a magnetic material by rotating its magnetization. [8] This paper explains the magnetic effect of the electric current from the observed effects of the accelerating electrons, causing naturally the experienced changes of the electric field potential along the electric wire. The accelerating electrons explain not only the Maxwell Equations and the Special Relativity, but the Heisenberg Uncertainty Relation, the wave particle duality and the electron's spin also, building the bridge between the Classical and Quantum Theories. The changing acceleration of the electrons explains the created negative electric field of the magnetic induction, the changing relativistic mass and the Gravitational Force, giving a Unified Theory of the physical forces. Taking into account the Planck Distribution Law of the electromagnetic oscillators also, we can explain the electron/proton mass rate and the Weak and Strong Interactions.

Aiming at the special circumstance in which UAVs swarm are used in the mode of battlefield extending, a message delivery scheme called AWJPMMD (ARIMA-WNN Joint Prediction Model based Message Delivery) is proposed. In this scheme, the LET (Link Expiration Time) of the center node and the proxy node is calculated by high precision GPS information, then the LET at next moment is predicted by ARIMA-WNN (Autoregressive Integrated Moving Average model - Wavelet Neural Network) Joint Prediction Model. Finally, the process of message delivery is affected by the predicted value of LET and other parameters. The target information is sent to the UAVs ground station in form of store-and-forward by the message delivery process. Simulation shows that this scheme can provide higher message delivery ratio and this scheme is more stable.

With the fast advancement in the field of network security everything gets the chance to be possible on web. Remote user authentication is an imperative system in the networks framework to check the exactitude of remote user over the public channel. In this authentication procedure, server checks accreditation of the user that user is authentic and legal one or not. For that Server and user commonly confirm each other and make a same session key for encryption of upcoming conversations. There are two types of authentication: Single server and Multi server. To overcome the drawback of single server authentication (remembering id and pswd for accessing each of the server), the concept of Multi server comes, in which user first register with RC, and whatever servers are registerd under RC can be accessed by user by providing single id and pswd for all. Here We review US patent [US 9264425 B1] scheme which is based on Multi server authentication, we provide mathematical analysis of the same with some attacks found on it.

The researchers, in their paper published in Science Advances, say this freedom allows quantum computers to store many different states of the system being simulated in different superpositions, using less memory overall than in a classical computer. [26] The advancement of quantum computing faces a tremendous challenge in improving the reproducibility and robustness of quantum circuits. One of the biggest problems in this field is the presence of noise intrinsic to all these devices, the origin of which has puzzled scientists for many decades. [25] Characterising quantum channels with non-separable states of classical light the researchers demonstrate the startling result that sometimes Nature cannot tell the difference between particular types of laser beams and quantum entangled photons. [24] Physicists at Princeton University have revealed a device they've created that will allow a single electron to transfer its quantum information to a photon. [23] A strong, short light pulse can record data on a magnetic layer of yttrium iron garnet doped with Co-ions. This was discovered by researchers from Radboud University in the Netherlands and Bialystok University in Poland. The novel mechanism outperforms existing alternatives, allowing the fastest read-write magnetic recording accompanied by unprecedentedly low heat load. [22] It goes by the unwieldy acronym STT-MRAM, which stands for spin-transfer torque magnetic random access memory. [21] Memory chips are among the most basic components in computers. The random access memory is where processors temporarily store their data, which is a crucial function. Researchers from Dresden and Basel have now managed to lay the foundation for a new memory chip concept. [20] Researchers have built a record energy-efficient switch, which uses the interplay of electricity and a liquid form of light, in semiconductor microchips. The device could form the foundation of future signal processing and information technologies, making electronics even more efficient. [19] The magnetic structure of a skyrmion is symmetrical around its core; arrows indicate the direction of spin. [18]

Area detectors are used in many scientific and technological applications such as particle and radiation physics. Thanks to the recent technological developments, the radiation sources are becoming increasingly brighter and the detectors become faster and more efficient. The result is a sharp increase in the size of data collected in a typical experiment. This situation imposes a bottleneck on data processing capabilities, and could pose a real challenge to scientific research in certain areas. This article proposes a number of simple techniques to facilitate rapid and efficient extraction of data obtained from these detectors. These techniques are successfully implemented and tested in a computer program to deal with the extraction of X-ray diffraction patterns from EDF image files obtained from CCD detectors.

Collatz' conjecture (stated in 1937 by Collatz and also named Thwaites conjecture, or Syracuse, 3n+1 or oneness problem) can be described as follows:
Take any positive whole number N. If N is even, divide it by 2. If it is odd, multiply it by 3 and add 1. Repeat this process to the result over
and over again. Collatz' conjecture is the supposition that for any positive integer N, the sequence will invariably reach the value 1.
The main contribution of this paper is to present a new approach to Collatz' conjecture. The key idea of this new approach is to clearly differentiate
the role of the division by two and the role of what we will name here the jump: a = 3n + 1.
With this approach, the proof of the conjecture is given as well as generalizations for jumps of the form qn + r and for jumps being polynomials
of degree m >1.

Dynamic programming is a technique that can yield relatively efficient solutions to computational problems in economics, genomic analysis, and other fields. But adapting it to computer chips with multiple "cores," or processing units, requires a level of programming expertise that few economists and biologists have. [16] Researchers at Lancaster University's Data Science Institute have developed a software system that can for the first time rapidly self-assemble into the most efficient form without needing humans to tell it what to do. [15] Physicists have shown that quantum effects have the potential to significantly improve a variety of interactive learning tasks in machine learning. [14] A Chinese team of physicists have trained a quantum computer to recognise handwritten characters, the first demonstration of " quantum artificial intelligence ". Physicists have long claimed that quantum computers have the potential to dramatically outperform the most powerful conventional processors. The secret sauce at work here is the strange quantum phenomenon of superposition, where a quantum object can exist in two states at the same time. [13] One of biology's biggest mysteries-how a sliced up flatworm can regenerate into new organisms-has been solved independently by a computer. The discovery marks the first time that a computer has come up with a new scientific theory without direct human help. [12] A team of researchers working at the University of California (and one from Stony Brook University) has for the first time created a neural-network chip that was built using just memristors. In their paper published in the journal Nature, the team describes how they built their chip and what capabilities it has. [11] A team of researchers used a promising new material to build more functional memristors, bringing us closer to brain-like computing. Both academic and industrial laboratories are working to develop computers that operate more like the human brain. Instead of operating like a conventional, digital system, these new devices could potentially function more like a network of neurons. [10] Cambridge Quantum Computing Limited (CQCL) has built a new Fastest Operating System aimed at running the futuristic superfast quantum computers. [9] IBM scientists today unveiled two critical advances towards the realization of a practical quantum computer. For the first time, they showed the ability to detect and measure both kinds of quantum errors simultaneously, as well as demonstrated a new, square quantum bit circuit design that is the only physical architecture that could successfully scale to larger dimensions. [8] Physicists at the Universities of Bonn and Cambridge have succeeded in linking two completely different quantum systems to one another. In doing so, they have taken an important step forward on the way to a quantum computer. To accomplish their feat the researchers used a method that seems to function as well in the quantum world as it does for us people: teamwork. The results have now been published in the "Physical Review Letters". [7] While physicists are continually looking for ways to unify the theory of relativity, which describes large-scale phenomena, with quantum theory, which describes small-scale phenomena, computer scientists are searching for technologies to build the quantum computer.

A revolutionary and emerging class of energy-harvesting computer systems require neither a battery nor a power outlet to operate, instead operating by harvesting energy from their environment. [18]
In 1959 renowned physicist Richard Feynman, in his talk "Plenty of Room at the Bottom," spoke of a future in which tiny machines could perform huge feats. Like many forward-looking concepts, his molecule and atom-sized world remained for years in the realm of science fiction. [17]
The race towards quantum computing is heating up. Faster, brighter, more exacting – these are all terms that could be applied as much to the actual science as to the research effort going on in labs around the globe. [16]
For the first time, scientists now have succeeded in placing a complete quantum optical structure on a chip, as outlined Nature Photonics. This fulfills one condition for the use of photonic circuits in optical quantum computers. [15]
The intricately sculpted device made by Paul Barclay and his team of physicists is so tiny it can only be seen under a microscope. But their diamond microdisk could lead to huge advances in computing, telecommunications, and other fields. [14]
Researchers from the Institute for Quantum Computing at the University of Waterloo and the National Research Council of Canada (NRC) have, for the first time, converted the color and bandwidth of ultrafast single photons using a room-temperature quantum memory in diamond. [13]
One promising approach for scalable quantum computing is to use an all-optical architecture, in which the qubits are represented by photons and manipulated by mirrors and beam splitters. So far, researchers have demonstrated this method, called Linear Optical Quantum Computing, on a very small scale by performing operations using just a few photons. In an attempt to scale up this method to larger numbers of photons, researchers in a new study have developed a way to fully integrate single-photon sources inside optical circuits, creating integrated quantum circuits that may allow for scalable optical quantum computation. [12]
Spin-momentum locking might be applied to spin photonics, which could hypothetically harness the spin of photons in devices and circuits. Whereas microchips use electrons to perform computations and process information, photons are limited primarily to communications, transmitting data over optical fiber. However, using the spin of light waves could make possible devices that integrate electrons and photons to perform logic and memory operations. [11]

In this paper, we propose an ad-hoc on-demand distance vector routing algorithm for mobile ad-hoc networks taking
into account node mobility. Changeable topology of such mobile ad-hoc networks provokes overhead messages in
order to search available routes and maintain found routes. The overheadmessages impede data delivery from sources
to destination and deteriorate network performance. To overcome such a challenge, our proposed algorithm estimates
link duration based neighboring node mobility and chooses the most reliable route. The proposed algorithm also
applies the estimate for route maintenance to lessen the number of overhead messages. Via simulations, the proposed
algorithmis verified in variousmobile environments. In the low mobility environment, by reducing routemaintenance
messages, the proposed algorithm significantly improves network performance such as packet data rate and end-toend
delay. In the high mobility environment, the reduction of route discovery message enhances network performance
since the proposed algorithm provides more reliable routes.

This paper fills in some blanks left between part 1 of this series, Kalman Folding (http://vixra.org/abs/1606.0328), and the rest of the papers in the series. In part 1, we present basic Kalman filtering as a functional fold, highlighting the advantages of this form for hardening code in a test environment. In that paper, we motivated the Kalman filter as a natural extension of the running average and variance, writing both as functional folds computed in constant memory. We expressed the running statistics as recurrence relations, where the new statistic is the old statistic plus a correction. We write the correction as a gain factor times some transform of a residual. The residual is the difference between the current (old) statistic and the incoming (new) observation. In both expressions, for brevity, we left derivations to the reader. Here, we present those derivations in full “school-level” detail, along with some basic explanation of the programming language that mechanizes the computations.

Based on creating generalized and hybrid set and library with neutrosophy and quad-stage method, this paper presents the concept of "computer information library clusters" (CILC). There are various ways and means to form CILC. For example, CILC can be considered as the "total-library", and consists of several "sub-libraries". As another example, in CILC, a "total-library" can be set up, and a number of "sub-libraries" are side by side with the "total-library". Specially, for CILC, the operation functions can be added; for example, according to "natural science computer information library clusters" (natural science CILC), and applying "variation principle of library (or sub-library)", “partial and temporary unified theory of natural science so far” with different degrees can be established. Referring to the concept of “natural science CILC”, the concepts of “social science CILC”, “natural science and social science CILC”, and the like, can be presented. While, referreing to the concept of “computer information library clusters”, the concepts of “computer and non-computer information library clusters”, “earth information library clusters”, “solar system information library clusters”, “Milky Way galaxy information library clusters”, “universe information library clusters”, and the like, can be presented.

We propose an O(n log n) algorithm for evaluation of bivariate Kolmogorov- Smirnov statistics (n is number of samples). It offers few orders of magnitude of speedup over existing implementations for n > 100k samples of input. The algorithm is based on static Binary Search Trees and sweep algorithm. We share C++ implementation with Python bindings.

Internet of Things (IoT) is one of the most disruptive technologies now- adays which can efficiently connect, control and manage intelligent objects those are connected to the Internet. IoT based applications like smart education, smart agriculture, smart health-care, smart homes etc which can deliver services with- out manual intervention and in a more effective manner. In this work, we have proposed a IoT based smart home automation system using a micro-controller based Arduino board and mobile based Short Message service (SMS) application working functionality. Wi connectivity has been used to establish the communi- cation between the Arduino module and automated home appliances. We have proposed a real-time scheduling strategy that offers a novel communication pro- tocol to control the home environment with the switching functionality. Our sim- ulation results show that the proposed strategy is quite capable to achieve high performance with different simulation scenarios.

Usando um novo conceito de linguagem variável, já provei anteriormente que P≠NP, mas tal prova não utilizou nenhum dos problemas clássicos conhecidos como NP-completos, a exemplo de SAT (satisfatibilidade, satisfiability), caixeiro-viajante (travelling-salesman), soma de subconjuntos (subset-sum), da mochila (knapsack), programação linear inteira (integer linear programming), etc. Tal prova não implica que sendo P≠NP então devemos ter NP-completo ∉P, ou seja, os mencionados famosos problemas difíceis podem ainda ser resolvidos em tempo polinomial, sem precisar encerrar a pesquisa nesta direção. Tal como ocorre com o método simplex, que pode resolver em tempo polinomial a grande maioria dos problemas de programação linear, também é possível resolver SAT em tempo polinomial na maioria das vezes, que é o que eu mostro neste trabalho.

A QR algorithm was designed using sparse matrix techniques for likelihood evaluation in REML. The efficiency of the algorithm depends on how the order of columns in the mixed model array are arranged. Three heuristic orderings were considered. The QR algorithm was tested successfully in likelihood evaluation, but vector processing was needed to finish the procedure because of excess fill-ins. The improvements made for the QR algorithm also applied to the competing absorption approach, and hence absorption was found to be more competitive than the QR algorithm in terms of computing time and memory requirements. Absorption was made 52 times faster than a first generation absorption algorithm.

In this paper, ellipsoid method for linear programming is derived using only minimal knowledge of algebra and matrices.
Unfortunately, most authors first describe the algorithm, then later prove its correctness, which requires a good knowledge of linear algebra.

Sorting is one of the most researched topics of Computer Science and it is one of the essential operations across computing devices. Given the ubiquitous presence of computers, sorting algorithms utilize significant percentage of computation times across the globe. In this paper we present a non-comparison based sorting algorithm with average case time complexity of O(n) without any assumptions on the nature of the input data.

The authors have recently shown that recognizing low fractional hypertree-width (fhw) is NP-complete
in the general case and that the problem becomes tractable if the hypergraphs under consideration have degree and intersection width bounded by a constant, i.e., every vertex is contained in only constantly many different edges and the intersection of two edges contains only constantly many vertices. In this article, we show that bounded degree alone suffices to ensure tractability.

We use the whole order approach to solve the problem of P versus NP. The relation of the whole order within a beautiful order is imperative to understanding the total order. We also show several techniques observed by the minimum element, we call a logical minimum. The perfect zero-knowledge technique will deliver exactly the same. We conclude with a demonstration of the halting problem.

In this paper, I investigate a prefix-free universal Turing machine (UTM) running multiple programs in parallel according to a scheduler. I found that if, over the course of the computation, the scheduler adjusts the work done on programs so as to maximize the entropy in the calculation of the halting probability Omega, the system will follow many laws analogous to the laws of physics. As the scheduler maximizes entropy, the result relies on algorithmic thermodynamics which connects the halting probability of a prefix-free UTM to the Gibb's ensemble of statistical physics (which also maximizes entropy). My goal with this paper is to show specifically, that special relativity and general relativity can be derived from algorithmic thermodynamics under a certain choice of thermodynamic observables applied to the halting probability.

The bordering method of the Cholesky decomposition is backward differentiated to derive a method of calculating first derivatives. The result is backward differentiated again and an algorithm for calculating second derivatives results. Applying backward differentiation twice also generates an algorithm for conducting forward differentiation. The differentiation methods utilize three main modules: a generalization of forward substitution for calculating the forward derivatives; a generalization of backward substitution for calculating the backward derivatives; and an additional module involved with the calculation of second derivatives. Separating the methods into three modules lends itself to optimization where software can be developed for special cases that are suitable for sparse matrix manipulation, vector processing and/or blocking strategies that utilize matrix partitions. Surprisingly, the same derivative algorithms fashioned for the Cholesky decomposition of a positive definite matrix can be used again for matrices that are indefinite. The only differences are very minor adjustments involving an initialization step that leads into backward differentiation and a finalization step that follows forward differentiation.

We utilize a previously reported methodological framework [5], to find a general set of mappings for any satisfiability (SAT) problem to a set of arithmetized codes allowing a classification hierarchy enumerable via integer partition functions. This reveals a unique unsatisfiability criterion via the introduction of certain universal indicator functions associating the validity of any such problem with a mapping between Mersenne integers and their complements in an inclusive hierarchy of exponential intervals. Lastly, we present means to reduce the complexity of the original problem to that of a special set of binary sequences and their bit block analysis via a reduction of any expression to a type of a Sequential Dynamical System (SDS) using the technique of clause equalization. We specifically notice the apparent analogy of certain dynamical properties behind such problems with resonances and coherencies of multi-periodic systems leading to the possibility of certain fast analog or natural implementations of dedicated SAT-machines. A Matlab toolbox is also offered as additional aid in exploring certain simple examples.

This paper describes the backward differentiation of the Cholesky decomposition by the bordering method. The backward differentiation of the Cholesky decomposition by the inner product form and the outer product form have been described elsewhere. It is found that the resulting algorithm can be adapted to vector processing, as is also true of the algorithms developed from the inner product form and outer product form. The three approaches can also be fashioned to treat sparse matrices, but this is done by enforcing the same sparse structure found for the Cholesky decomposition on a secondary work space.
