Approaches to the intellectualization of information and telecommunication networks security control in transport

The specifics of modern information and telecommunication networks in transport, as an object of information security control, are investigated. The main trends in the development of information and telecommunication network protection technologies (TNPT) have been identified. The presence of the interrelation of the main integrative properties: readiness, mobility, throughput, stealth, accessibility, manageability, which is a consequence of the convergence of information transmission and processing technologies, is noted. A new integrative property of ITCS has become the presence and characteristics of distributed system memory, which allows storing transmitted messages for a certain time. An important feature of modern TNPT is the presence of artificial intelligence, which is formed on the basis of information and algorithmic support of modern TNPT, providing flexibility of the system behavior. These trends indicate the transformation of TNPT into a supersystem, the management tasks of which are insufficiently investigated at present. The purpose of this work is to study new approaches to ensuring the safety management of modern TNPT critical infrastructure, which includes modern systems of sea and river transport, taking into account their features. The object of the study is the information security control system of modern TNPT. The subject of the study is the scientific and methodological support of the TNPT critical infrastructure control. The research objectives are to analyze existing and develop new conceptual frameworks, as well as approaches to improving the TNPT information security control system based on intellectualization methods. The analysis of the existing methodology for managing complex organizational and technical systems and information security control technologies is carried out. The concept of TNPT information security control is formalized schematically. The analysis of the existing approach to the organization of the TNPT information security control process is carried out. The tasks of control intellectualization are defined. The problem of ensuring the efficiency and reliability of the TNPT control is formulated.

Time-Frequency Signatures of Electronic Coherence of Colloidal CdSe Quantum Dot Dimer Assemblies Probed at Room Temperature by Two-Dimensional Electronic Spectroscopy.

Electronic coherence signatures can be directly identified in the time-frequency maps measured in two-dimensional electronic spectroscopy (2DES). Here, we demonstrate the theory and discuss the advantages of this approach via the detailed application to the fast-femtosecond beatings of a wide variety of electronic coherences in ensemble dimers of quantum dots (QDs), assembled from QDs of 3 nm in diameter, with 8% size dispersion in diameter. The observed and computed results can be consistently characterized directly in the time-frequency domain by probing the polarization in the 2DES setup. The experimental and computed time-frequency maps are found in very good agreement, and several electronic coherences are characterized at room temperature in solution, before the extensive dephasing due to the size dispersion begins. As compared to the frequency-frequency maps that are commonly used in 2DES, the time-frequency maps allow exploiting electronic coherences without additional post-processing and with fewer 2DES measurements. Towards quantum technology applications, we also report on the modeling of the time-frequency photocurrent response of these electronic coherences, which paves the way to integrating QD devices with classical architectures, thereby enhancing the quantum advantage of such technologies for parallel information processing at room temperature.

Evaluation of the Maturity of Urban Energy Internet Development Based on AHP-Entropy Weight Method and Improved TOPSIS

With the rapid development of communication technology and information processing technology, the construction of the Urban Energy Internet (UEI) has become one of the important construction elements of the new power system, and it is necessary to assess and analyse its development status and potential. However, the results of the current assessment of the maturity of UEI development are relatively rare, and the transformation path of urban smart energy construction needs to be studied in depth. On this basis, this study aims to propose an improved and comprehensive evaluation model for the maturity of UEI development. This study first considers the dynamic development process of the UEI and proposes an evaluation index system for the maturity of UEI development that includes three dimensions of development status, development benefits and development prospects. Secondly, a comprehensive evaluation model based on GRA-KL-TOPSIS is constructed by using the AHP-entropy weighting method to calculate the combined weights of indicators and considering the Kulla back-Leibler distance to replace the Euclidean distance in the traditional evaluation method. Finally, the maturity of Energy Internet development is calculated for five typical first-tier cities in China (Beijing, Shanghai, Guangzhou, Tianjin and Shenyang), and the final ranking of the five cities is Shanghai > Beijing > Guangzhou > Tianjin > Shenyang. The results of the study prove the scientific validity of the model. Compared to the unimproved Topsis method, the evaluation results calculated based on the improved Topsis evaluation model are more objective and realistic in reflecting the score and rating of the cities. The analysis of the empirical results shows that cities at different stages of development should make up for their shortcomings and increase their investment in infrastructure development, technological innovation and the introduction of talents in order to accelerate the digital and intelligent development of energy.

Ultrafast Laser Control of Antiferromagnetic-Ferrimagnetic Switching in Two-Dimensional Ferromagnetic Semiconductor Heterostructures.

Realizing ultrafast control of magnetization switching is of crucial importance for information processing and recording technology. Here, we explore the laser-induced spin electron excitation and relaxation dynamics processes of CrCl3/CrBr3 heterostructures with antiparallel (AP) and parallel (P) systems. Although an ultrafast demagnetization of CrCl3 and CrBr3 layers occurs in both AP and P systems, the overall magnetic order of the heterostructure remains unchanged due to the laser-induced equivalent interlayer spin electron excitation. More crucially, the interlayer magnetic order switches from antiferromagnetic (AFM) to ferrimagnetic (FiM) in the AP system once the laser pulse disappears. The microscopic mechanism underpinning this magnetization switching is dominated by the asymmetrical interlayer charge transfer combined with a spin-flip, which breaks the interlayer AFM symmetry and ultimately results in an inequivalent shift in the moment between two FM layers. Our study opens up a new idea for ultrafast laser control of magnetization switching in two-dimensional opto-spintronic devices.

Integrated Broadband Mode Division Demultiplexer in Waveguide Arrays

On-chip mode division (de)multiplexing plays a significant role in integrated devices to greatly improve communication capacity. One of the goals of mode division (de)multiplexing is to realize devices with larger bandwidth and better fabrication tolerance. However, integrated broadband mode division (de)multiplexing devices have rarely been reported up to now. In this work, we experimentally realize a broadband mode division demultiplexing device with a high degree of fabrication tolerance based on a lithium niobate-on-insulator waveguide array. By taking advantage of the fact that different modes in the waveguide array have different group velocities, we experimentally confirm that different modes in the waveguide array have different transverse displacements. The implementation of the integrated broadband mode division demultiplexer may have future applications in information processing technology, quantum communication, and quantum computing.

Managing Information Technology Risks to Achieve Business Goals: A Case of Pharmaceutical Company

Extant literature has shown that sectoral characteristics play a critical role in business value creation through information technology (IT). Therefore, managing IT and its associated risks needs to consider specific industrial traits to understand the distinct business nature and regulations that shape IT-enabled business value creation. This study presents an in-depth analysis of business goals, IT processes, and IT risks in the case of a pharmaceutical company through which appropriate controls are designed to ensure business value creation through IT. Drawing on a case study of a pharmaceutical company in Indonesia, we found that managing IT risks in the pharmaceutical industry entails two main objectives: 1) ensuring compliance with external laws and regulations as well as internal policies, 2) supporting the optimization of business functions, processes, and costs. Throughout one year of engagement during the project, this study identified ten risks associated with the operation of business processes. Risks are dominated by moderate levels given the current state of controls and appetite, most of which emerge from the company’s existing internal processes. Internal actors are involved in all risks, with most events occurring due to laws and regulations. Further, the study designs and elaborates IT risk controls by drawing from COBIT 5 Seven Enablers. Overall, IT risk management through cascading processes of analysis ensures the alignment of IT risk controls with achieving business goals in the pharmaceutical industry.

RETRACTED ARTICLE: Intelligent system simulation and data accuracy of physical fitness training for sports majors based on real-time status update of wearable Internet of Things

With the development of modern science and technology, sports training has begun to develop in the direction of new ideas, new technologies and new equipment. Wearable devices with wireless data transmission and real-time feedback functions are more and more widely used in sports training, providing a simpler and more scientific way to explore the biological significance of sports training. In this paper, the wearable Internet of Things is applied to the intelligent system simulation of physical training for sports majors. With the support of the Internet of Things technology, wearable devices can quickly capture the movement data of students' physical training and quickly transmit this information to the intelligent system of physical training for sports majors, so that the system can be updated in real time. Wearable devices are high-tech products developed in the context of big data. The use of wearable devices to achieve sports training and data collection is only an external manifestation of sports scientific monitoring. The collection and statistics of the original sports data obtained through more scientific information processing technology is the focus of sports scientific monitoring. At present, the use of wearable devices in sports training also has some measurement errors, which affect the validity and credibility of data. Data processing is not systematic and perfect, and the compatibility and connectivity are low. Statistical analysis is a common way to analyze sports training data at home and abroad. This paper discusses the physical training data based on the status update of the wearable object network and uses the optimized data processing method to improve the accuracy of the data.

Coherent stimulated amplification of the skyrmion breathing

Magnetic skyrmions are topological solitons and have great potential applications in next-generation spintronic devices for information storage and processing technologies. Here, we present an approach using the master equation involving the thermal noise to obtain the dynamical evolution of the skyrmion breathing based on the three-magnon scattering in a magnetic film, and develop a two-step model to obtain the approximated analytic solution. We show that the skyrmion breathing experiences a process where the thermal noise competes with the time-varying gain in the step I. Then the excited magnon number of the skyrmion breathing mode undergoes exponential growth with the evolutionary time due to the generation of negative total damping rate induced by the microwave drive field in the step II, which is referred to as coherent stimulated amplification of the skyrmion breathing. The analytic result is shown to be in good agreement with numerical calculation. We also obtain the threshold power of the coherent stimulated amplification behavior. In addition to offering insight into the nonlinear dynamics of skyrmions, potential applications range from realizing skyrmion cooling to providing excitation source for PT-symmetric skyrmionic systems.

Magnon Blockade and Magnon–Atom Entanglement Induced by a Qutrit Coupled to a Ferromagnetic YIG Sphere

AbstractHybridized magnonic–photonic systems promise novel applications for future information processing technologies. Here, a hybrid magnonic system comprising of a qutrit (Λ‐type three‐level atom) and a ferromagnetic YIG sphere is considered. Indeed, the whole system is driven by two light fields under the influence of the thermal environment. The indirect magnon–atom interaction is established via the virtual photon exchange. The associated Lindblad master equation is derived and its solution is found to investigate the nonclassical feature, especially in the steady‐state solution. Generally, the system shows considerable nonclassicality, that is, strong magnon antibunching and magnon blockade. In fact, the feasibility of using such a hybrid system to prepare a single‐magnon source based on magnon blockade effects we theoretically demonstrated. Besides, the considered system may be exploited to generate robust and stable magnon–atom entanglement. The appearance of magnon blockade and magnon–atom entanglement in the Λ‐type atom may have its origin in the fact that the atom is trapped in different superposition states, induced by the quantum interference phenomenon. The proposed model and the corresponding results may open up an intriguing prospect to prepare a single‐magnon source and provide further benefits through concatenating with photons in optomagnonic systems.

Parallel Finite Field Algorithms for Communications and Sensor Networks

Sensor network integrates sensor technology, embedded computing technology, modern network and wireless communication technology, distributed information processing technology, etc. It can monitor, perceive and collect the information of various environments or monitoring objects in real time through various integrated micro sensors, and process the information through the embedded system. The perceived information is transmitted to the user terminal by multi-hop relay through the random ad-hoc wireless communication network. The coding of communications and sensor networks affects the efficiency of communication. The main coding technology is based on finite field. Among operations in finite fields, divisions are time-consuming operations since they are generally computed via inversions and multiplications. We present techniques to exploit extend binary trees for fast divisions in finite fields. We implement the finite field algorithm on Field Programmable Logic Arrays (FPGAs) in a parallel way. The implementation result from FPGAs shows that the parallel finite field algorithm can speed up the process of coding of communications and sensor networks.

Dynamical Behavior of Pure Spin Current in Organic Materials.

Growing concentration on the novel information processing technology and low-cost, flexible materials make the spintronics and organic materials appealing for the future interdisciplinary investigations. Organic spintronics, in this context, has arisen and witnessed great advances during the past two decades owing to the continuous innovative exploitation of the charge-contained spin polarized current. Albeit with such inspiring facts, charge-absent spin angular momentum flow, namely pure spin currents (PSCs) are less probed in organic functional solids. In this review, the past exploring journey of PSC phenomenon in organic materials are retrospected, including non-magnetic semiconductors and molecular magnets. Starting with the basic concepts and the generation mechanism for PSC, the representative experimental observations of PSC in the organic-based networks are subsequently demonstrated and summarized, by accompanying explicit discussion over the propagating mechanism of net spin itself in the organic media. Finally, future perspectives on PSC in organic materials are illustrated mainly from the material point of view, including single molecule magnets, complexes for the organic ligands framework as well as the lanthanide metal complexes, organic radicals, and the emerging 2D organic magnets.

Material-Inherent Noise Sources in Quantum Information Architecture.

NISQ is a representative keyword at present as an acronym for "noisy intermediate-scale quantum", which identifies the current era of quantum information processing (QIP) technologies. QIP science and technologies aim to accomplish unprecedented performance in computation, communications, simulations, and sensing by exploiting the infinite capacity of parallelism, coherence, and entanglement as governing quantum mechanical principles. For the last several decades, quantum computing has reached to the technology readiness level 5, where components are integrated to build mid-sized commercial products. While this is a celebrated and triumphant achievement, we are still a great distance away from quantum-superior, fault-tolerant architecture. To reach this goal, we need to harness technologies that recognize undesirable factors to lower fidelity and induce errors from various sources of noise with controllable correction capabilities. This review surveys noisy processes arising from materials upon which several quantum architectures have been constructed, and it summarizes leading research activities in searching for origins of noise and noise reduction methods to build advanced, large-scale quantum technologies in the near future.

Modeling and scheduling of production systems by using max-plus algebra

Max-plus algebra provides mathematical methods for solving nonlinear problems by using linear equations. These kinds of the problems arise in areas such as manufacturing, transportation, allocation of resources, and information processing technology. In this paper, the scheduling of production systems consisting of many stages and different units is considered, where some of the units can be used for many stages. If a production unit is used for different stages cleaning is needed in between, while no cleaning is needed between stages of the same type. Cleaning of units takes a significant amount of time, which is considered in the scheduling. The goal is to minimize the total production time, and such problems are often solved by using numerical optimization. In this paper a max-plus formalism is used for the modeling and scheduling of such production systems. Structural decisions such as choosing one unit over another proved to be difficult in the latter case, but this can be viewed as a switching max-plus linear system. No switching (and thus no cleaning) is considered as a base case, but for larger production batches the durability constraints will require switches. Switching as seldom as possible is shown to be optimal. Scheduling of a small production system consisting of 6 stages and 6 units is used as a case study.

Microwave-to-optical transduction with erbium ions coupled to planar photonic and superconducting resonators

Optical quantum networks can connect distant quantum processors to enable secure quantum communication and distributed quantum computing. Superconducting qubits are a leading technology for quantum information processing but cannot couple to long-distance optical networks without an efficient, coherent, and low noise interface between microwave and optical photons. Here, we demonstrate a microwave-to-optical transducer using an ensemble of erbium ions that is simultaneously coupled to a superconducting microwave resonator and a nanophotonic optical resonator. The coherent atomic transitions of the ions mediate the frequency conversion from microwave photons to optical photons and using photon counting we observed device conversion efficiency approaching 10−7. With pulsed operation at a low duty cycle, the device maintained a spin temperature below 100 mK and microwave resonator heating of less than 0.15 quanta.
