Authors:   Moscow Technical University of Communications and Informatics, Gorgadze Svetlana F. , Maximov Anton A. ,   Moscow Technical University of Communications and Informatics
Published: January 2021

The analysis and generalization of the main publications on the methods of synthesis and analysis of non-linear active microwave circuits based on the use of the harmonic balance method are presented. As a result of some classification of mathematical approaches and techniques used in the context of this method, a selection and review of basic algorithms was made, the sequential application of which makes it possible to obtain the final result for a scheme of any complexity. The principles of drawing up the initial system of differential equations for electronic circuits and reducing it to a system of linear algebraic equations are considered. A detailed and, at the same time, simplified interpretation of the approaches involving the use of projection methods and Krylov subspaces is given in order to make them easier to understand. Both the complete and the restart generalized method of minimal residuals are considered, in which the desired solution is obtained in the course of an iterative process, at each stage of which subspaces of lower dimension are constructed. The possibilities of simulators and application packages intended for circuit design of electronic circuits are considered. The problem of matching a power amplifier in large signal mode using the APLAC simulator, which is NI AWR technology for designing high-frequency circuits, is discussed.

The development of IoT concept makes it necessary to search and improve models and methods for analyzing the state of remote autonomous devices. Due to the fact that some devices are located outside the controlled area, it becomes necessary to develop universal models and methods for identifying the state of low-power devices from a computational point of view, using complex approaches to analyzing data coming from various information channels. The article discusses an approach to identifying IoT devices state, based on parallel functioning classifiers that process time series received from elements in various states and modes of operation. The aim of the work is to develop an approach for identifying the state of IoT devices based on time series recorded during the execution of various processes. The proposed solution is based on methods of parallel classification and statistical analysis, requires an initial labeled sample. The use of several classifiers that give an answer "independently" from each other makes it possible to average the error by "collective" voting. The developed approach is tested on a sequence of classifying algorithms, to the input of which the time series obtained experimentally under various operating conditions were fed. Results are presented for a naive Bayesian classifier, decision trees, discriminant analysis, and the k nearest neighbors method. The use of a sequence of classification algorithms operating in parallel allows scaling by adding new classifiers without losing processing speed. The method makes it possible to identify the state of the Internet of Things device with relatively small requirements for computing resources, ease of implementation, and scalability by adding new classifying algorithms.

For cloud service providers, one of the most relevant tasks is to maintain the required quality of service (QoS) at an acceptable level for customers. This condition complicates the work of providers, since now they need to not only manage their resources, but also provide the expected level of QoS for customers. All these factors require an accurate and well-adapted mechanism for analyzing the performance of the service provided. For the reasons stated above, the development of a model and algorithms for estimation the required resource is an urgent task that plays a significant role in cloud systems performance evaluation. In cloud systems, there is a serious variance in the requirements for the provided resource, as well as there is a need to quickly process incoming requests and maintain the proper level of quality of service – all of these factors cause difficulties for cloud providers. The proposed analytical model for processing requests for a cloud computing system in the Processor Sharing (PS) service mode allows us to solve emerging problems. In this work, the flow of service requests is described by the Poisson model, which is a special case of the Engset model. The proposed model and the results of its analysis can be used to evaluate the main characteristics of the performance of cloud systems.

Представлены результаты исследования электрохимической активности биорезорбируемого магниевого сплава Mg–0,8Ca в среде для культивирования клеток млекопитающих – minimum essential medium (MEM). Наиболее высокая коррозионная активность сплава выявлена на начальной стадии выдержки в растворе (первые 12 мин). Установлен механизм коррозионной деградации материала, заключающийся в инициировании разрушения на границах зерен вследствие образования микрогальванических пар. Это объясняется присутствием в сплаве интерметаллидной фазы Mg2Ca, являющейся анодной по отношению к α-матрице магния. Предложена модель формирования слоя продуктов коррозии на поверхности сплава при его выдержке в MEM.

The paper presents results of study of electrochemical activity of the Mg–0.8Ca bioresorbable alloy in a medium for the cultivation of mammalian cells – the minimum essential medium (MEM). The highest corrosion activity of the alloy was revealed at the initial stage of exposure in the solution (for the first 12 minutes). The mechanism of corrosion degradation of material has been determined and it is characterized with initiation of the destruction at grain boundaries caused by the formation of micro-galvanic couples. It is explained by the presence of Mg2Ca intermetallic phase which is anodic against α- magnesium matrix. A model of formation of corrosion products layer on alloy`s surface during the exposition in MEM solution is proposed.

Published: January 2021

Рассматриваются концепция и реализация контрольно-аварийной системы (КАС), которая направлена на повышение живучести автономных необитаемых подводных аппаратов (АНПА) различного класса и назначения. Задача повышения живучести АНПА решается одновременно по нескольким направлениям: дублирование программных и аппаратных средств, а также обеспечение их взаимного согласованного (не противоречивого) функционирования. КАС создана на базе иерархической декомпозиции решаемых задач и включает в себя несколько уровней программного обеспечения, а также аппаратную часть. Программная часть КАС выполняет контроль целостности программного обеспечения, предстартовую диагностику, мониторинг ошибок и аварий. Аппаратная часть КАС обеспечивает возможность обнаружения и подъема АНПА в случае выхода из строя его вычислительной системы. Ключевой особенностью предлагаемого подхода является «относительно независимое» поведение систем в различных режимах работы (как штатных, так и аварийных), а также способность КАС в максимальном объеме выполнять заложенную программу-задание (миссию). Рассматриваются различные сценарии поведения АНПА во время возникновения нештатных ситуаций.

The work considers the concept and implementation of an emergency control system (ECS) to increase the survivability of autonomous underwater vehicles (AUV) of different types and functionality. The task of raising the AUV survivability can be solved in several ways: dual redundancy of software and hardware means and providing their mutual coherent (consistent) functioning. ECS is based on a hierarchal decomposition of solving tasks and includes several software layers and hardware components. The ECS software component controls the software's integrity, prelaunch diagnostic, errors, and emergency monitoring. The ECS hardware component provides capabilities of positioning and emersion of AUV in case of its computational system malfunction. The key feature of the proposed approach is the "relatively independent" behavior of the systems in different operational modes (both routine and emergency) and the capability of the ECS to perform the predetermined task (mission) to the maximum extent. Different scenarios of AUV behavior in emergencies are considered.

Published: January 2021

Hautatahdossa on lain mukaan kyse vainajan autonomian ja katsomusten kunnioittamisesta.  Tämä artikkeli analysoi läheisensä menettäneiden kertomuksia hautatahdosta ja siitä, miten he ovat pyrkineet huomioimaan vainajan tahdon hautajaisten suunnittelussa ja hautauspaikan valinnassa.  Artikkelin aineisto muodostuu kolmentoista surevan läheisen haastatteluista, jotka on analysoitu temaattisella sapluuna-analyysillä. Tulokset osoittavat, että osassa tapauksista vainaja oli selkeästi ilmaissut toiveensa hautaussuunnitelmista, mutta osassa tapauksista kyse oli oletetun hautatahdon ilmaisuista. Katsomukset vaikuttivat vainajan hautatoiveisiin erityisesti silloin kun hänellä oli ollut selvä uskonnollinen tai ei-uskonnollinen vakaumus. Vainajan, surevan läheisen ja muiden läheisten relaatioilla oli iso merkitys vainajan hautatahdon seuraamisessa. Tutkimuksemme osoitti, että uusperhetilanne hankaloitti vainajan hautatahdon noudattamista erityisesti niissä tilanteissa, joissa läheisillä oli erilaisia tulkintoja vainajan toiveista. Mitä selvemmin vainaja on ilmaissut toiveensa hautausrituaalista, hautatavasta ja hautapaikasta läheisilleen, sitä helpompi hautajaiset on järjestää. Tämä säästää läheisiä turhilta riidoilta ja mielipahalta.

The road to long-term memory: Top-down attention is more effective than bottom-up attention for forming long-term memories
Authors: Sasin Edyta , Fougnie Daryl
Published: January 2021

Does the strength of representations in long-term memory (LTM) depend on which type of attention is engaged? We tested participants’ memory for objects seen during visual search. We compared implicit memory for two types of objects—related-context nontargets that grabbed attention because they matched the target defining feature (i.e., color; top-down attention) and salient distractors that captured attention only because they were perceptually distracting (bottom-up attention). In Experiment 1, the salient distractor flickered, while in Experiment 2, the luminance of the salient distractor was alternated. Critically, salient and related-context nontargets produced equivalent attentional capture, yet related-context nontargets were remembered far better than salient distractors (and salient distractors were not remembered better than unrelated distractors). These results suggest that LTM depends not only on the amount of attention but also on the type of attention. Specifically, top-down attention is more effective in promoting the formation of memory traces than bottom-up attention.

The Geometry of Power Systems Steady-State Equations– Part I: Power Surface
Authors: Ayuev B. , Davydov V. , Erokhin P. , Neuymin V. , Pazderin A.
Published: January 2021

Steady-state equations play a fundamental role in the theory of power systems and computation practice. These equations are directly or mediately used almost in all areas of the power system state theory, constituting its basis. This two-part study deals with a geometrical interpretation of steady-state solutions in a power space. Part I considers steady states of the power system as a surface in the power space. A power flow feasibility region is shown to be widely used in power system theories. This region is a projection of this surface along the axis of a slack bus active power onto a subspace of other buses power. The findings have revealed that the obtained power flow feasibility regions, as well as marginal states of the power system, depend on a slack bus location. Part II is devoted to an analytical study of the power surface of power system steady states.
Modeling Kilonova Light Curves: Dependence on Nuclear Inputs

Published: January 2021

The mergers of binary neutron stars, as well as black hole–neutron star systems, are expected to produce an electromagnetic counterpart that can be analyzed to infer the element synthesis that occurred in these events. We investigate one source of uncertainties pertinent to lanthanide-rich outflows: the nuclear inputs to rapid neutron capture nucleosynthesis calculations. We begin by examining 32 different combinations of nuclear inputs: eight mass models, two types of spontaneous fission rates, and two types of fission daughter product distributions. We find that such nuclear physics uncertainties typically generate at least one order of magnitude uncertainty in key quantities such as the nuclear heating (one and a half orders of magnitude at 1 day post-merger), the bolometric luminosity (one order of magnitude at 5 days post-merger), and the inferred mass of material from the bolometric luminosity (factor of 8 when considering the 8–10 day region). Since particular nuclear processes are critical for determining the electromagnetic signal, we provide tables of key nuclei undergoing β-decay, α-decay, and spontaneous fission important for heating at different times, identifying decays that are common among the many nuclear input combinations.
The Effects of Biconical Outflows on Lyα Escape from Green Peas
Authors: Carr Cody , Scarlata Claudia , Henry Alaina , Panagia Nino
Published: January 2021

We analyze the spectra of 10 Green Pea galaxies, previously studied by Henry et al., using a semi-analytical line transfer model to interpret emission and absorption features observed in UV galactic spectra. We focus our analysis on various ionization states of silicon, associated with the cool (∼104 K) and warm (∼105 K) gas. By analyzing low-ionization lines, we study the relationships between the distribution and kinematics of the outflowing H i gas and the observed Lyα escape fraction,

, as well as the Lyα emission peak separation, Δpeak. We find that outflow geometries that leave a portion of the source uncovered along the line of sight create the best conditions for Lyα escape and have narrow peak separations, while geometries that block the observer’s view of the source create the worst conditions for Lyα escape and have large peak separations. To isolate the effects of outflow kinematics, we restrict our testing set to galaxies with spherical outflows and find that

and the Lyα luminosity both increase with the extent of the galactic winds. A simple estimate suggests that the collisional excitation of neutral hydrogen by free electrons in the cool gas of the winds can account for the Lyα luminosity observed in these objects. Finally, we speculate on the relationship between outflows and the escape of ionizing radiation from the circumgalactic medium.
Evolution of Three-dimensional Coherent Structures in Hall Magnetohydrodynamics
Authors: Bora K. , Bhattacharyya R. , Smolarkiewicz P. K.
Published: January 2021

This work extends the computational model EULAG-MHD to include Hall magnetohydrodynamics (HMHD)—important to explore physical systems undergoing fast magnetic reconnection at the order of the ion inertial length scale. Examples include solar transients along with reconnections in magnetosphere, magnetotail, and laboratory plasmas. The paper documents the results of two distinct sets of implicit large-eddy simulations in the presence and absence of the Hall forcing term, initiated with an unidirectional sinusoidal magnetic field. The HMHD simulation while benchmarking the code also emphasizes the complexity of three-dimensional (3D) evolution over its two-dimensional counterpart. The magnetic reconnections onset significantly earlier in HMHD. Importantly, the magnetic field generated by the Hall term breaks any inherent symmetry, ultimately making the evolution 3D. The resulting 3D reconnections develop magnetic flux ropes (MFRs) and magnetic flux tubes. Projected on the reconnection plane, the ropes and tubes appear as magnetic islands, which later break into secondary islands, and finally coalesce to generate an X-type neutral point. These findings are in agreement with the theory and contemporary simulations of HMHD, and thus verify our extension of the EULAG-MHD model. The second set explores the influence of the Hall forcing on generation and ascend of an MFR from sheared magnetic arcades—a novel scenario instructive in understanding the coronal transients. The rope evolves through intermediate complex structures, ultimately breaking locally because of reconnections. Interestingly, the breakage occurs earlier in the presence of the Hall term, signifying faster dynamics leading to magnetic topology favorable for reconnections.

Progress in the three-dimensional modeling of supernovae (SNe) prompts us to revisit the supernova remnant (SNR) phase. We continue our study of the imprint of a thermonuclear explosion on the SNR it produces, which we started with a delayed detonation model of a Chandrasekhar-mass white dwarf. Here we compare two different types of explosion models, each with two variants: two delayed detonation models (N100ddt, N5ddt) and two pure deflagration models (N100def, N5def), where the N number parameterizes the ignition. The output of each SN simulation is used as input to an SNR simulation carried on until 500 yr after the explosion. While all SNR models become more spherical over time and overall display the theoretical structure expected for a young SNR, clear differences are visible among the models, depending on the geometry of the ignition and on the presence or not of detonation fronts. Compared to N100 models, N5 models have a strong dipole component and produce asymmetric remnants. N5def produces a regular-looking, but offset remnant, while N5ddt produces a two-sided remnant. Pure deflagration models exhibit specific traits: a central overdensity, because of the incomplete explosion, and a network of seam lines across the surface, boundaries between burning cells. Signatures from the SN dominate the morphology of the SNR up to 100–300 yr after the explosion, depending on the model, and are still measurable at 500 yr, which may provide a way of testing explosion models.
Systematic Study of AGN Clumpy Tori with Broadband X-Ray Spectroscopy: Updated Unified Picture of AGN Structure

Published: January 2021

We present the results of a systematic, broadband X-ray spectral analysis of nearby active galactic nuclei (AGNs) with the X-ray clumpy torus model (XCLUMPY). By adding 16 AGNs newly analyzed in this paper, we study a total of 28 AGNs, including unabsorbed and absorbed AGNs taken from Ichikawa et al. and García-Bernete et al. This is the largest sample whose X-ray and infrared spectra are analyzed by the clumpy torus models XCLUMPY and CLUMPY, respectively. The relation between the Eddington ratio and the torus covering factor determined from the X-ray torus parameters of each object follows the trend found by Ricci et al. based on a statistical analysis. We confirm the results by Tanimoto et al. that (1) the torus angular widths determined by the infrared data are larger than those by the X-ray data and (2) the ratios of hydrogen column density to V-band extinction (N
H/A

V
) along the line of sight in obscured AGNs are similar to the Galactic value, on average. Unobscured AGNs show apparently smaller line-of-sight N
H/A

V
ratios than the Galactic one. Our findings can be well explained by an updated unified picture of AGN structure including a dusty torus, dusty polar outflows, and dust-free gas, where the inclination determines the X-ray and optical classifications and observed torus properties in the X-ray and infrared bands.

Published: January 2021

We present a major update to the 3D coronal rope ejection (3DCORE) technique for modeling coronal mass ejection flux ropes in conjunction with an approximate Bayesian computation (ABC) algorithm that is used for fitting the model to in situ magnetic field measurements. The model assumes an empirically motivated torus-like flux rope structure that expands self-similarly within the heliosphere, is influenced by a simplified interaction with the solar wind environment, and carries along an embedded analytical magnetic field. The improved 3DCORE implementation allows us to generate extremely large ensemble simulations that we then use to find global best-fit model parameters using an ABC sequential Monte Carlo algorithm. The usage of this algorithm, under some basic assumptions on the uncertainty of the magnetic field measurements, allows us to furthermore generate estimates on the uncertainty of model parameters using only a single in situ observation. We apply our model to synthetically generated measurements to prove the validity of our implementation for the fitting procedure. We also present a brief analysis, within the scope of our model, of an event captured by the Parker Solar Probe shortly after its first flyby of the Sun on 2018 November 12 at 0.25 au. The presented toolset is also easily extendable to the analysis of events captured by multiple spacecraft and will therefore facilitate future multipoint studies.

Published: January 2021

Diaporthe species have often been reported as important plant pathogens, saprobes and endophytes on a wide range of plant hosts. Although several Diaporthe species have been recorded, little is known about species able to infect forest trees in Jiangxi Province. Hence, extensive surveys were recently conducted in Jiangxi Province, China. A total of 24 isolates were identified and analysed using comparisons of DNA sequence data for the nuclear ribosomal internal transcribed spacer (ITS), calmodulin (cal), histone H3 (his3), partial translation elongation factor-1α (tef1) and β-tubulin (tub2) gene regions, as well as their morphological features. Results revealed five novel taxa, D. bauhiniae, D. ganzhouensis, D. schimae, D. verniciicola, D. xunwuensis spp. nov. and three known species, D. apiculatum, D. citri and D. multigutullata.

The Coffee Region of Colombia is one of the most representative areas of the country due to its cultural appeal. 200 of the 528 mammal species in the country occur in this region. Pre-existing knowledge about the group in this region has been obtained through indirect and direct sampling methods. We present new records of mammals of the “Reserva Forestal Protectora Bosques de la Central Hidroeléctrica de Caldas (CHEC)”, located in the Coffee Region, based on vouchered citizen science records. To accomplish this, we held training workshops on the relevance of information provided by non-invasive vouchers for mammal collections that include bone remains, hairs, skin and other signs that can be found incidentally in the field by park rangers and other staff of the Reserve. In addition, we included photographic and video records of mammals taken by park rangers before and after the training workshops. We added vouchers obtained by the park rangers to the biological collection of the Natural History Museum of the Universidad de Caldas (MHN-UCa). Using this method, we obtained records of 34 mammalian species belonging to 20 families and 11 orders. We highlight the obtention of museum preserved vouchers of the Northern Naked-tailed Armadillo, Cabassous centralis (Miller 1899), and the Cauca Slender Opossum, Marmosops caucae (Thomas 1900), that had limited samples in national collections or had not been previously collected in the study area. With this work, a contribution network with the CHEC reserve staff was established, promoting the inclusion of these agents in the development of scientific research, and showing the relevance of collaborative science in assisting with filling information gaps about medium and large mammals.
This is not a scandal in Luxembourg
Authors: Majerus Benoît
Published: January 2021

Au début des années 1970, Investors Overseas Service (IOS), une société panaméenne dirigée par l’homme d’affaires américain Bernie Cornfeld, dont certaines filiales sont domiciliées au Luxembourg, a connu un effondrement spectaculaire. C’est la première fois que la place financière luxembourgeoise apparaît dans les médias locaux et internationaux comme acteur d’un monde financier globalisé. L’effondrement d’IOS, qualifié de scandale luxembourgeois par certains organes de presse européens, n’a pas été décrit dans les mêmes termes par la presse et par l’élite politique luxembourgeoises. Cette étude de cas examine comment les scandales (financiers) éclatent et se clôturent dans des pays de taille réduite.
La fiscalité est-elle source de distorsions entre les trois secteurs (privé lucratif, privé non lucratif et public) dans le domaine des interventions sociales et médico-sociales ?
Authors: Lagay Jean-Pierre
Published: January 2021

Cet article a pour objet de présenter le régime fiscal applicable aux établissements et services sociaux et médico-sociaux selon qu’ils sont gérés par le secteur privé lucratif, le secteur privé sans but lucratif ou le secteur public. Certains établissements comme les établissements pour personnes âgées dépendantes ou les crèches peuvent être gérés par les trois secteurs. Pour chacun des trois secteurs, sont étudiés successivement l’impôt sur les sociétés, la tva et la taxe sur les salaires et les impôts locaux. Cette étude est illustrée par le cas pratique des établissements pour personnes âgées dépendantes. Certaines distorsions fiscales sont justifiées. D’autres concernant notamment les impôts locaux le sont moins, au bénéfice du secteur public et au détriment du secteur privé non lucratif. Il est peu probable qu’elles puissent être corrigées dans un proche avenir.
