All optical tunable RF filter using elemental antimony

Abstract In the past decade, the proliferation of modern telecommunication technologies, including 5G, and the widespread adoption of the Internet-of-things (IoT) have led to an unprecedented surge in data generation and transmission. This surge has created an escalating demand for advanced signal processing capabilities. Microwave photonic (MWP) processors offer a promising solution to satisfy this unprecedented demand for data processing by capitalising on the high bandwidth and low latency achievable by optical systems. In this work, we introduce an integrated MWP processing unit for all-optical RF filtering using elemental antimony. We exploit the crystallisation dynamics of antimony to demonstrate a photonic leaky integrator, which is configured to operate as a first-order low-pass filter with a bandwidth of 300 kHz and ultra-compact footprint of 16 × 16 μm2. We experimentally demonstrate the implementation of such a filter as an envelope detector to demodulate an amplitude-modulated signal. Finally, a discussion on achieving bandwidth tunability is presented.

Возможности правовой самозащиты лиц при распространении сведений, порочащих их деловую репутацию

The dissemination of information discrediting the business reputation of an organisation or a citizen is one of the main factors hindering the normal economic or professional activities of a person, as well as entailing financial losses and loss of trust on the part of counterparties and (or) clients of a person. At the same time the potential or already incurred damage, especially in view of rapid development of modern information and telecommunication technologies, should be levelled not only through jurisdictional protection, but also in the form of legal self-defense, which, unlike judicial and other jurisdictional protection of law,takes a variety of forms and differs as to the speed of implementation. But the analysis of available possibilities of legal self-defense revealed that not all forms of self-defense of business reputation are equally effective. Thus, the placement of the response, replica or comment of the affected person in the media or other data sources that are available to counterparties and clients of the person, including with the application of evidence of inconsistency of defamatory information with reality, is clearly more effective than attempts to remove defamatory information from a specific source: this is because of almost uncontrolled dissemination of information on the Internet and the possibility of duplicating this information on other media. In addition, it should be noted that the self-defense of business reputation must meet the conditions of proportionality and ethical correctness, since otherwise the protection of the right may take the form of an offense and present the affected person as intolerant to negative opinions about him, after which the general public will be reluctant to deal with him, which may entail additional losses due to the refusal of clients and counterparties to enter into any legal relationship with this citizen or organisation.

WORK PERFORMANCE AND WORK FROM HOME: THEORETICAL DEVELOPMENT

Employee job performance has been associated with management since its inception as a scientific discipline. The goal of proper management of human activity is to achieve higher job performance. In its current form, job performance is not only associated with quantity, but quality as well. From the point of view of an organization's leadership, managers or supervisors within the work environment, in the past, leading their employees to better job performance was relatively easy. With the progress of science and technology, a gradual change connected with the introduction of information and communication technology can be seen and certain types of work started to shift significantly to the home environment. This trend was greatly accelerated by the Covid-19 pandemic when, as part of interventions to prevent the spread of the virus, organisations had to react by introducing work from home wherever possible. Working from home is gradually becoming a working standard that is being used by more and more employers and employees. Many employers, also thanks to the pandemic period, have found that several kinds of costs can be saved by introducing work-from-home. On the other hand, working from home has become equally convenient for employees, bringing many advantages, but on the other hand also disadvantages, such as loss of social contact or more complicated teamwork. Of course, working from home brings other aspects, such as changing factors and the environment where work is realised, which is also connected to work performance. The aim of this paper is to identify, based on a literature review, key research themes related to work performance and working from home. To identify relevant literature, Web of Science database was selected while this research focuses on peer-reviewed publications published in English language up to April 2023. The total scope of the selected publications analysed based on the Prisma methodology is 14 research articles between 2008 and 2023. The published studies includes the following research directions: 1. Change in work performance in the context of the implementation of Covid-19 interventions, 2. Gender roles and their impact on work from home and work performance, 3. Mental and emotional aspects at home and the allocation of time for work, 4. The use of modern telecommunication technologies their impact on teamwork in the context of work from home. These 14 studies are found in several journals (n-11). The first study in the final set is from 2008. Based on a dataset taken from Web of Science (the keyword string "work performance and work from home"), a map of the keywords and the most cited authors extracted from that string was created. These maps are created using the analytical tool VOSviewer. Based on the publications analysed, the most frequently cited author was identified (Bakker A.B.) The findings of this study contribute to the literature related to work performance and working from home.

НЕКОТОРЫЕ АСПЕКТЫ ДЕЯТЕЛЬНОСТИ ОРГАНОВ ВНУТРЕННИХ ДЕЛ НА ТРАНСПОРТЕ ПО ПРОТИВОДЕЙСТВИЮ ПРЕСТУПЛЕНИЯМ, СОВЕРШАЕМЫМ С ИСПОЛЬЗОВАНИЕМ ИНФОРМАЦИОННО-ТЕЛЕКОММУНИКАЦИОННЫХ ТЕХНОЛОГИЙ

Modern information and telecommunication technologies are increasingly finding their application not only in the professional and daily activities of people, but also in the criminal environment for criminal purposes. The popularity of such technologies is due to the ability to carry out criminal actions remotely, without being in direct contact with the victim or third parties. This reduces the risk of detection for criminals. The article discusses some aspects concerning the activities of employees of the internal affairs bodies in transport to counteract crimes committed using information technology at railway, water and air transport facilities. The proposals aimed at improving the effectiveness of the prevention and disclosure of this type of crime are formulated.

LINGUAL AND STYLISTICAL SPECIFICS OF THE ENGLISH MOBILE NOVEL

The article examines the linguistic and stylistic features of a new genre of literature — the mobile novel. It is noted that the development of communica- tion technologies in the period of the end of the 20th and the beginning of the 21st centuries became the impetus for the emergence of hybrid forms that arose during the transition of classical genres to a new for them interactive environ- ment and the development of new means of artistic expression based on modern telecommunication technologies, which include mobile novel. It was determined that the purely linguistic features of the texts of this genre include the use of abbre- viations; colloquial, simplified and lapidary style; frequent omission of dramatic dialogues, which allows the reader to independently guess and interpret what they have read; the sharp unfolding of plots often keeps the reader in suspense and stimulates anticipation of the next part. The graphic stylistic devices of the mo- bile novel include the use of capitalization, phonetic repetitions (alliteration or assonance), the use of emoji, unconventional punctuation (the use of hyphens, infinity signs, exclamation marks in the middle of the sentence, etc.). During the experimental study, the linguistic stylistic features of the mobile novel “Second- Hand Memories” by the English-speaking author of Japanese origin Takatsu were analyzed. In the process of research, the compositional structure, plot line, roles of the main characters, as well as linguistic stylistic phenomena of the three levels of language — phonographical, lexical and grammatical, and syntactic — were analyzed.

Crystal structure of barium manganese vanadate BaMnV2O7

Relevance. The development of materials with excellent dielectric properties is crucial for modern telecommunications. The value of this study lies in the importance of examining these properties in the context of expanding possibilities for high-frequency applications in modern telecommunication technologies, including 4G and 5G communication. Purpose. The purpose of this study is to investigate the crystal structure of the compound BaMnV2O7 and its dielectric properties. Methodology. To achieve the set purpose, methods of analysis, experimentation, comparison, and computer modelling were used. Within this study, the material of low-temperature co-fired ceramics (LTCC) was thoroughly examined, known for its high efficiency as moisture protection. Results. A structural model for the compound BaMnV2O7 was proposed and investigated. In particular, it was found that the radius of Mn2+ (0.75 Å) is almost identical to the radius of Zn2+ (0.68 Å), confirming the similarity of the crystal structures of BaMnV2O7 and BaZnV2O7. The main results showed that pyrovanadate has a monoclinic symmetry and has a spatial symmetry group P121/c1 (14), characterised by lattice parameters: a=5.6221(5) Å, b=15.271(1) Å, c=9.7109(8) Å, β=123.702(3)°. The divergence factor was 9.05, indicating the model’s correspondence to experimental data. Additionally, the density of the compound was calculated, amounting to 4.2699 g/cm3. Conclusions. Experimental data confirmed the presence of interatomic distances within 1.33-3.47 Å. The minimum interatomic distance in the compound structure is 1.33 Å between oxygen (O5) and vanadium (V2) atoms. The maximum interatomic distance is 3.47 Å observed between oxygen (O1) and (O2) atoms. With characteristics such as low dielectric permittivity (εr~8.9) and a high quality factor coefficient (Qu×f 31362 GHz), the compound BaMnV2O7 exhibits excellent microwave dielectric properties. The practical value of the obtained results lies in the potential development and improvement of materials with high dielectric properties, such as BaMnV2O7, for their application in telecommunication technologies, contributing to the development of more compact and reliable components for electronics

Copyright and Advertising Activities: Problems of Legal Regulation and Judicial Practice

Relevance. The development of modern information and telecommunication technologies and means of communication leads to a constant increase in the volume of advertising and its importance for the promotion of goods, works and services. At the same time, the creation of advertising in a significant part of cases is associated with the use of photographic, musical, literary works, works of fine art and other objects of copyright and related rights. The peculiarities related to the use of works and objects of related rights in advertising activities are not fully taken into account by the current legislation, which leads in practice to a number of negative consequences, in particular, to the recovery of disproportionate compensation in some cases and to the possibility of circumventing the established legal requirements in others.The purpose of the study is to develop theoretical provisions defining the peculiarities of the use of works in the implementation of advertising activities, characterizing the essence of legal relations arising in this case.Objectives: to identify the problems associated with the use of copyright objects in the implementation of advertising activities; to determine the peculiarities of legal relations formed in the process of implementation of advertising activities with the use of copyright objects; to determine the directions of further development of legal regulation of the issues under consideration.Methodology.

The article is a continuation of the author's scientific research on issues related to copyright protection, intellectual property rights and legal regulation of advertising activities.

Triplet-Triplet Energy Transfer in Bis-Cyclometalated Iridium Complexes with Pyrene-Substituted Isocyanides.

Nonlinear optical (NLO) materials are able to modulate responses of electromagnetic radiation, leading to phenomena critical to modern telecommunications technologies. The last two decades have seen significant advances in the area of molecular nonlinear chromophores, particularly with respect to reverse-saturable absorption (RSA). Here, we introduce a strategy for intense excited-state absorption (ESA) that involves bis-cyclometalated iridium complexes with isocyanide ancillary ligands decorated with pyrene triplet acceptors. Upon excitation, the complexes undergo rapid triplet-triplet energy transfer (TTET) to the acceptor excited states. This report describes five bis-cyclometalated iridium complexes using two different pyrene-substituted isocyanides with the general formula [Ir(C^N)2(CNAr)2]PF6 (C^N = cyclometalating ligand, CNAr = isocyanide ancillary ligand: CNArpyr = 2,6-dimethyl-4-(1-pyrenyl)phenyl isocyanide, CNpyr = 1-pyrenyl isocyanide). The synthesized complexes were thoroughly characterized via 1H and 13C{1H} NMR spectroscopy, Fourier-transform Infrared spectroscopy, and electrospray ionization mass spectrometry. The excited states were evaluated with UV-vis absorption, steady-state and time-resolved photoluminescence, and transient absorption spectroscopy. Phosphorescence is completely quenched at room temperature, but in the solvent glass matrix at 77 K, there is luminescence originating from a π → π* triplet state on the pyrene moiety, abbreviated herein as 3pyrene. All five complexes display intense and long-lived ESA originating from the 3pyrene state. The localization of the ground-state absorption on the cyclometalating ligands and the excited-state absorption on the pyrene moiety allows for independent tuning of ground-state absorption (GSA) and ESA to optimize RSA and other NLO attributes.

One-step method for the fabrication of pure and metal-decorated densified CNT films for effective electromagnetic interference shielding

Light-weight, thin, and robust electromagnetic shielding materials with high electrical conductivity are needed for advanced modern electronics and telecommunication technologies to protect circuits from electromagnetic interference. Carbon nanotubes (CNT) are ideal candidates for electromagnetic shielding materials due to their excellent mechanical strength, high electrical conductivity, and light weight. However, the relatively poor electrical conductivity of CNT films, a result of the many points of contact resistance between neighboring CNTs, is an obstacle towards their utilization as a shielding material. Here, we propose a facile CNT film fabrication method that enhances the conductivity of CNT films by collapsing the separation between neighboring CNTs (i.e., densifying the material) in the CNT network. The dense CNT films resulting from this facile method exhibit high electrical conductivity (∼106 S m-1), and achieve excellent shielding of 99.999992% (71 dB) at frequencies between 8.2 GHz and 12.4 GHz with a thickness of 14.3 μm. The remarkable absolute shielding effectiveness (3.50 × 105 dB cm-2 g-1) is due to the material's low density (i.e., ∼1.0 g/cm3), thinness (i.e., 1.3–14.3 μm), and metal-like conductivity. Also, the produced CNT sheet is an ideal substrate for gold decoration that can dramatically enhance the EMI shielding performance further (EMI SE increased from 43.90 dB in the loose film to 56.67 dB in the dense film, which further increased to 66.12 dB when the dense CNT film was coated with a thin gold layer). The outstanding properties of gold-decorated dense CNT films make them strong candidates to meet the electromagnetic shielding needs of modern cutting-edge, lightweight, and compact electronic devices.

Application of the method of equivalent message encoding structures to simplify coding complexity

Formulation of the problem. Modern telecommunication technologies make it possible to transmit data over long distances with limitations in the form of low power consumption and low error rate using error correction codes. The use of such codes plays an important role and is necessary to detect and correct errors caused by signal distortion and noise in the communication channel. According to Shannon's channel coding theorem, the probability of error can be arbitrarily small or close to zero if the encoding rate of transmission R is less than or equal to the bandwidth of channel C. Assuming that the bandwidth C is achievable, we can calculate the minimum signal-to-noise power ratio (SNR) to achieve zero error, or an arbitrarily small error called the Shannon limit, while maintaining R ≤ C. This article discusses a method of applying equivalent message encoding structures to construct low-density parity-checking (LDPC) codes. Low-density parity-checking (LDPC) codes are a class of linear block codes in which the complexity of iterative decoding increases linearly with increasing block length. Standard LDPC codes without modifications are considered to demonstrate the effectiveness of the proposed method, which is expected to provide high encoding speed when transmitting messages with a short block length. The method of obtaining equivalent structures allows: to reduce the computational complexity of encoding and decoding; to provide the possibility of finding a new encoding scheme and evaluating its effectiveness. The validity of the method for obtaining equivalent message encoding structures is evaluated by modeling the bit error rate (BER) of LDPC codes. Purpose. to show the effectiveness of the use of equivalent structures for various methods of compression of transmitted information, to minimize the complexity of encoding, while maintaining energy efficiency, correcting ability and data transfer rate. Results. A method is considered for obtaining equivalent message element encoding structures that can be used to create more LDPC codes for data transmission applications with a short block length. The cascade principle of constructing an equivalent generator and a parity check matrix was analyzed, which also leads to minimizing the computational complexity of the encoder and decoder. An equivalent structure G can be obtained from cascading two (or more) matrices by modifying the second matrix so that it has a unit matrix with the size of the parity check length and a shift to the right by k bits. On the other hand, the equivalent structure H can be obtained by simply cascading directly the second matrix and shifting to the right by k bits. According to the simulation results, the proposed method is adequate, since LDPC codes have the same BER characteristics as codes based on the low density generator matrix (LDGM). During the simulation, it was concluded that the SPC codes (single parity check (single parity check (SPC)) are the most efficient codes (for a given block length), since SPC codes have the smallest interval up to the Shannon limit. Practical significance. The results presented in this article will give a new insight into the development of simple channel coding of LDPC codes of short block length with high encoding speed for future applications with lower power consumption.

Impact of the correctional rehabilitation program on the walking locomotion of amateur athletes after brain contusion

The ascertaining experiment involved 38 men involved in amateur sports at the age of 25-42 years with the consequences of brain contusion in the late remote period. The issue of renewal of combatants by means of physical culture and sports rehabilitation for amateur sports becomes topical. A correctional and rehabilitation program was developed: stage 1 (28 days) was held on the basis of the Ukrainian Research Institute of Prosthetics, stage 2 (42 days) independently, but Gr1 was trained under the supervision of a specialist in physical culture and sports rehabilitation using modern telecommunication technologies. The difference of the program in Gr1 was the appointment in the variable component of the Neurac technique on the Redcord suspension system, instead of training on a multifunctional block simulator; Nordic walking instead of training walking; vestibular gymnastics. It was found that after the 2nd stage in amateur athletes Gr1, the assessment of muscle strength according to the Lovett test, indicators of the dynamic characteristics of walking, such as the coefficient of rhythm and load asymmetry, acquired a normative value. Gr2 men showed a slow improvement in all studied parameters. The formative experiment confirmed that a multidisciplinary approach, conducting independent classes under the supervision of a rehabilitation specialist positively affects the walking locomotion of amateur athletes with the consequences of a brain contusion and brings the return to sports closer.

Electromagnetic fields of cellular communication as a health risk factor for children and adolescents (review)

Modern telecommunication technologies rely on using radio-frequency electromagnetic field (RF EMF). They have brought many useful services into our life able to solve multiple issues. However, we should bear in mind that this exposure is open, uncontrollable and permanent. Given that, it seems relevant to investigate possible negative influence exerted by RF EMF on health of children and adolescents since this population group is the most vulnerable and sensitive to any external exposure. This review analyzes Russian and foreign studies with their focus on chronic influence of RF EMF created by cellular communication means on health of children (aged 6–10 years) and adolescents (aged 11–16 years). We have established several manifestations of health disorders in children and adolescents including asthenic syndrome (headache, irritability, increased fatigue, sleeping disorders, periodical pains in the heart and joints); mental deadaptation (anxiety, stress, depression, etc.); as well as their combinations. Along with all the aforementioned syndromes, effects produced by exposure to RF EMF become apparent through some indirect signs of memory and attention failure such as forgetfulness (inability to recall the necessary information in time) and inattention (inability to concentrate on an event or activity) and even through growing frequency of respiratory diseases. Basing on the analyzed studies by Russian and foreign researchers, we can conclude that they provide solid evidence of negative influence of electromagnetic fields created by cell phones on health of children and adolescents. Therefore, implementation of modern gadgets and their active use by children and adolescents should be accompanied with assessment of actual threats posed by them, health risk assessment, and development of scientifically substantiated standards for their safe use.

Dynamics of indicators of vestibular dysfunction and walking locomotion in men aged 25-42 years with the consequences of a combat wound as a result of the influence of physical culture and sports rehabilitation

The purpose of the study was to investigate and evaluate the dynamics of basometry and stabilometry in men aged 25-42 with the consequences of a combat injury.
 Material & Methods: examined 38 men aged 25-42 years with long-term consequences of closed craniocerebral injury in the late long-term period, which were divided into Gr1 (n=20) and Gr2 (n=18). Vestibular dysfunction, mobility was determined by the Bohannon and "TUG" tests. To determine the biomechanical characteristics of walking, a hardware-software basometric complex and methods of the Ukrainian Research Institute for Prosthetics, Prosthetic Engineering and Recovery were used.
 Results: when developing a correctional and rehabilitation program, thanks to the concept of the ICF, Smart goals were set. At stage 1 of inpatient rehabilitation (28 days), the program is composed of components. For men in both groups, the normative component was the same. Kinesitherapy, classes on the C-mill system, on the «Cosmos» treadmill, and massage were prescribed. Persons Gr1 in the variable part were trained on the Redcord suspension system, Nordic walking and vestibular gymnastics. The men of Gr2 were prescribed a general training on a multifunctional block simulator, training walking. At the 2nd stage (42 days) the persons of both groups were exercising independently, however, the persons of Gr1, with the help of modern telecommunication technologies, were exercising under the supervision of a specialist in physical rehabilitation. The dynamics of the balance indicator according to the Bohann test indicated that the persons Gr1 balance indicator almost approached the normative value. In Gr2 positive changes were observed, however, after stage 2 the difference was only 0.44 points compared with the dynamics of stage 1 (p>0,05). The dynamics of functional mobility and balance according to the "TUG" test indicated that the average time to complete the test after stage 2 approached the standard value. In patients, Gr2 tended to decrease (p>0,05). Biomechanical studies of statics, namely the coefficient of resistance, rotation of pressure centers, the common center of pressure in the frontal and sagittal plane in men Gr1 acquired significant differences (p<0,05); in men Gr2 tended to improve (p>0,05). The main indicators of walking locomotion, namely the pace and speed in men Gr1 and Gr2, acquired a standard value (p<0,05). The walking rhythm coefficient and load asymmetry index in men Gr2 did not acquire the normative value (p>0,05), in comparison with the indices of men Gr1 (p<0,05), who were engaged under the supervision of a specialist in physical culture and sports rehabilitation.
 Conclusions: the results of the study revealed a violation of walking in men aged 25-42 years with the consequences of a combat injury in the form of temporal, kinematic and dynamic asymmetry. The analysis of the dynamics of the parameters of vestibular dysfunction and walking locomotion confirmed the advantages of the author's program.
