description: The article considers the trends and directions of e-government development of Ukraine and the ad-vantages of its deployment. The main problems that arise at this and subsequent stages of e-government imple-mentation are analyzed. A comparative analysis with the leading countries in this area is done. "Narrow" months of e-government in Ukraine were identified according to the UN E-Government Survey 2018. An as-sessment of the level of e-government development in public authorities was made. The principle of a "single window" the Unified State Portal of Administrative Services (poslugy.gov.ua) is considered. The importance of implementing e-government at the local level is noted. Different approaches to the im-plementation of e-government at the local level are described, which are outlined in terms of "smart city" (smart city), "e-city" and "e-region". The methodology of the Civil Society Institute for evaluating the websites of local governments is considered. It is determined that the quality of information content and functionality of the website are mandatory and necessary requirements for the development of e-government in Ukraine. The main shortcomings of the official websites of public authorities and local governments and their search en-gines have been identified. It was found that the priority of e-government development is to complete the tran-sition to electronic document management in the process of document preparation by ministries and inter-agency cooperation. Indicators of the level of e-government in different countries in accordance with the re-sults of the UN E-Government Survey. Possible ways to overcome the problematic issues of e-government in Ukraine are identified: improvement of the regulatory framework and systematization of information legislation, expansion and modernization of the existing infrastructure of public authorities, namely computer fleet and structured cable networks.

Charge and spin fractionalization in strongly correlated topological insulators
Creators: name: Nikolic, Predrag
Publisher: name: arXiv
Year: 2011
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: We construct an effective topological Landau-Ginzburg theory that describes general SU(2) incompressible quantum liquids of strongly correlated particles in two spatial dimensions. This theory characterizes the fractionalization of quasiparticle quantum numbers and statistics in relation to the topological ground-state symmetries, and generalizes the Chern-Simons, BF and hierarchical effective gauge theories to an arbitrary representation of the SU(2) symmetry group. Our main focus are fractional topological insulators with time-reversal symmetry, which are treated as generalizations of the SU(2) quantum Hall effect.

A new non-quasi-static non-linear MOSFET model based on physical analysis

Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2005
Subjects: ING-INF/01 Elettronica

description: This paper presents a novel approach to the physical modelling of Si based sub-micron MOSFETs. The model is based on a set of simplified transport equations for the conducting channel in a MOSFET. These equations incorporate non-quasi-static (NQS) effects due to the inclusion of time derivatives, and describe the semiconductor dynamics in terms of coupled particle and displacement currents leading to a description in terms of a relatively small number of nonlinear differential equations. Thus, internal device behaviour can be accurately modelled. A new method of modelling the charge density in the channel has also been developed in the form of a single expression that describes the charge under the Gate for any biasing conditions. The new model has a low empirical content, and is fully continuous over all operating regions.

Die vorliegende Studie ermittelte anhand einer Befragung den aktuellen Gesundheitszustand, arbeitsbezogene psychische Belastungen und daraus resultierende Beanspruchungen sowie vorhandene individuelle Ressourcen in dieser Berufsgruppe und führte einen Vergleich zwischen Stichproben aus zwei Städten Charkiw (Ukraine) und Magdeburg (Deutschland) in Bezug auf die berufliche Position der Studienteilnehmer durch. Insgesamt nahmen an der Befragung 173 Bankangestellte aus beiden Städten teil. Die Probanden wurden in vier Gruppen unterteilt: 22 leitende (33,2 ± 8,23 J.) bzw. 61 nicht leitende (30,4 ± 5,32 J.) Bankmitarbeiter aus der Ukraine und 17 leitende (43,7 ± 8,67 J.) bzw. 73 nicht leitende (43,3 ± 9,47 J.) Bankmitarbeiter aus Deutschland. Die Mitarbeiter in einer leitenden Position sowohl in der Ukraine als auch in Deutschland sind nach ihrer subjektiven Einschätzung nicht so vielen Stressfaktoren ausgesetzt im Vergleich zu ihren nicht leitenden Kollegen. Der subjektiv eingeschätzte gesundheitliche Zustand und die Belastungssituation der ukrainischen Bankangestellten sind dabei generell besser als in der deutschen Stichprobe. Die festgestellten Gesundheitsprobleme korrelieren positiv mit zunehmendem Alter – unabhängig vom Land und der innegehabte Position. Die Erkenntnisse aus der vorliegenden Studie könnten eine gute Grundlage für die die Erarbeitung von Präventionsempfehlungen für die vergleichbaren Bankinstitutionen sein, um Gesundheitsbeeinträchtigungen durch arbeitsbedingten Stress zu minimieren.

description: We present results on the clustering of 282,068 galaxies in the Baryon Oscillation Spectroscopic Survey (BOSS) sample of massive galaxies with redshifts 0.4~10%) in the correlation functions for scales less than ~1 Mpc/h and ~10-40 Mpc/h. A more realistic abundance matching model and better statistics from upcoming observations are needed to clarify the situation. We also estimate that about 12% of the "galaxies" in the abundance-matched sample are satellites inhabiting central haloes with mass M>~1e14 M_sun/h. Using the MultiDark simulation we also study the real space halo bias b(r) of the matched catalogue finding that b=2.00+/-0.07 at large scales, consistent with the one obtained using the measured BOSS projected correlation function. Furthermore, the linear large-scale bias depends on the number density n of the abundance-matched sample as b=-0.048-(0.594+/-0.02)*log(n/(h/Mpc)^3). Extrapolating these results to BAO scales we measure a scale-dependent damping of the acoustic signal produced by non-linear evolution that leads to ~2-4% dips at ~3 sigma level for wavenumbers k>~0.1 h/Mpc in the linear large-scale bias.

description: Several versions of the exponentially weighted moving average (EWMA) control chart, such as the generally weighted moving average (GWMA), the double, triple, and quadruple EWMA (DEWMA, TEWMA, and QEWMA), and the homogeneously weighted moving average (HWMA) charts, have been developed to enhance its detection ability, especially for small and moderate shifts. These charts have been criticized as it is considered that an appropriately designed EWMA chart provides as good or better zero-state and steady-state average run-length (ARL) performance. In this article, we perform a careful comparison study of the above control charts under similar in-control (IC) run-length properties. We show that the “new” memory-type control charts have better out-of-control (OOC) run-length characteristics, especially for small to moderate shifts in the process mean for both the zero-state and steady-state cases, except for the HWMA chart where its steady-state OOC performance is very poor. We also present a comparison study based on the worst-case ARL measure. Finally, the extensions of the EWMA chart have better IC robustness ability than the EWMA and HWMA charts.

Also scientifically substantiated results of the analysis of varietal resources and productivity of the studied phytocenoses according to their agroecological plasticity and grain productivity in the conditions of climate change in the zone of the right-bank Forest-steppe of Ukraine. The most promising varieties by maturity group, yield level are determined. Therefore, the most productive varieties were identified. Various technological aspects of cultivation have been studied in order to ensure the rational use of natural potential, which will further contribute to the expansion of sown areas of these plants. The relevance of the research is justified by the objectives of applied research on the ba-sis of research sites of Vinnytsia National Agrarian University ("Development of methods for improving the technology of growing legumes using biofertilizers, bacterial preparations, foliar fertilizers and physiological-ly active substances"). The introduction into production practice of highly productive varieties of legumes will reduce the deficit of vegetable protein, as well as improve the physico-chemical and phytosanitary conditions of the soil.

description: We propose a distributed algorithm, named Distributed Alternating Direction Method of Multipliers (D-ADMM), for solving separable optimization problems in networks of interconnected nodes or agents. In a separable optimization problem there is a private cost function and a private constraint set at each node. The goal is to minimize the sum of all the cost functions, constraining the solution to be in the intersection of all the constraint sets. D-ADMM is proven to converge when the network is bipartite or when all the functions are strongly convex, although in practice, convergence is observed even when these conditions are not met. We use D-ADMM to solve the following problems from signal processing and control: average consensus, compressed sensing, and support vector machines. Our simulations show that D-ADMM requires less communications than state-of-the-art algorithms to achieve a given accuracy level. Algorithms with low communication requirements are important, for example, in sensor networks, where sensors are typically battery-operated and communicating is the most energy consuming operation.

description: A series of Monte Carlo results for GaAs MESFETs with sub-micron gate length are presented. The study is based on a self consistent simulation that couples the Monte Carlo procedure for charge transport in GaAs to a Poisson solver defined on a two di­mensional grid. Channel electrons can reach velocities that largely exceed the saturation velocity (velocity overshoot). Such effect (enhanced by the reduction of gate length) guarantees very fast transit times in submicron structures. A comparison with the results obtained using a Drift-Diffusion algorithm are presented, which show the inadeguacy of tradition simulators in dealing with submicron structures.

description: According to the statistical information of the advancement indicators of Ukraine, a multiple regression model was developed for such a general indicator of employment as the number of employed people of Ukraine (dependent variable). Factors (independent variables) that affect the value of this indicator have been identi-fied. A preliminary econometric analysis of the model was performed: correlation fields were developed and statistical characteristics of the samples were determined, on the basis of which the data of statistical samples were checked whether they keep in with the standard distribution law; paired correlation coefficients are cal-culated and the closeness (density) of the bond between all model variables is estimated; independent varia-bles that have the greatest impact on the number of employed people in Ukraine have been identified. A multi-factor regression model was constructed, the significance of which was verified by Fisher’s F-statistics, and the parameters of the models were verified by Student’s t-statistics with a confidence probability of p = 0.95. The model was verified for multicollinearity and autocorrelation. The model developed can be used to improve the planning and adjustment of the employed population of Ukraine. The proposed methodology can also be used to develop appropriate models for any region of Ukraine.

description: We derive the ac dielectric loss in glasses due to resonant processes created by two-level systems and a swept electric field bias. It is shown that at sufficiently large ac fields and bias sweep rates the nonequilibrium loss tangent created by the two fields approaches a universal maximum determined by the bare linear dielectric permittivity. In addition this nonequilibrium loss tangent is derived for a range of bias sweep rates and ac amplitudes and show that the loss tangent creates a predicted loss function that can be understood in a Landau-Zener theory and which can be used to extract the TLS density, dipole moment, and relaxation rate.

Ecological genomics of kokanee salmon
Creators: name: Lemay, Matthew Alexander
Publisher: name: University of British Columbia
Year: 2014

description: Divergent natural selection across a heterogeneous landscape can drive the evolution of locally adapted populations in which phenotypic variation is fine-tuned to the environment. At the molecular level, such processes can be inferred by identifying correlations between genetic variation and environmental variables. In this dissertation, I used multiple complementary approaches to investigate the genetic basis of adaptation in natural populations of kokanee, the freshwater form of sockeye salmon (Oncorhynchus nerka). In Chapter 2, I found that the frequency and length of alleles in the circadian regulation gene, OtsClock1b, displays a predictable distribution with respect to latitude among lakes sampled from British Columbia to Alaska, providing evidence that variation at this locus may be locally adapted to divergent photoperiod regimes. In Chapter 3, I tested for transcriptome-wide patterns of sequence divergence in reproductive ecotypes of kokanee within Okanagan Lake and found evidence for differential gene expression and asymmetrical pathogen load between ecotypes. In Chapter 4, I used restriction site associated DNA sequencing to identify ~6,000 single nucleotide polymorphisms (SNPs) from multiple spawning populations of kokanee within Okanagan Lake; statistical outlier tests revealed 20 SNPs that were putatively under divergent selection between ecotypes, many of which annotated to genes associated with early development. While there was no evidence for neutral genetic divergence, outlier SNPs demonstrated significant structure with respect to ecotype and had high assignment accuracy (>99%) in mixed composition simulations, suggesting the utility of these loci for genetic stock identification. These data support the hypothesis that kokanee ecotypes are in the early stages of ecological differentiation, making them an ideal system for investigating the genomic basis of adaptation. Results from this study will be used to assist conservation and management initiatives by providing molecular tools for in-season monitoring of ecotype abundance.

description: We analyze an algorithm for computing a skew-Hermitian logarithm of a unitary matrix. This algorithm is very easy to implement using standard software and it works well even for unitary matrices with no spectral conditions assumed. Certain examples, with many eigenvalues near -1, lead to very non-Hermitian output for other basic methods of calculating matrix logarithms. Altering the output of these algorithms to force an Hermitian output creates accuracy issues which are avoided in the considered algorithm. A modification is introduced to deal properly with the $J$-skew symmetric unitary matrices. Applications to numerical studies of topological insulators in two symmetry classes are discussed.

description: GaAs MMICs mixers and oscillators have been fabricated for application to VHF-UHF and satellite TV tuners using a 0.7 mm gate length MESFET process available in the Philips Microwave Limeil Foundry, in France. Various mixer configurations have been evaluated which show improved intermodulation/noise figure performance as compared to silicon bipolar circuits. Best circuits have input IP3 over 10 dBm with associated noise figure lower than 10 dB at 2 GHz. The oscillators tested are the multivibrator-type and common gate Clapp differential configurations. Although the fully integrated GaAs VCO's do not meet the phase noise requirements yet, GaAs VCO's coupled to an external hybrid resonator appear however as a good solution to achieve low phase noise wide band VCO's at frequencies higher than 2 GHz.

description: This paper is concerned with giving the proof that there is a general decoupling property of vacuum and nonvacuum gravitational field equations in Einstein gravity and $f(R,T)$-modifications. The constructions are possible in terms of geometric and physical objects adapted to certain nonholonomic 2+2 splitting with local fibred structure. This allows us to generate exact and/or parametric depending solutions with generic off-diagonal metrics and generalized, or Levi-Civita, connections. Different classes of modified spacetimes are determined by corresponding generating and integration functions depending, in general, on all space and time coordinates and may possess, or not, Killing symmetries. The initial data sets for the Cauchy problem and their global properties are analyzed. There are formulated the criteria of evolution with spacetime splitting and decoupling of fundamental field equations. Examples of exact solutions defining ellipsoid deformations of black hole metrics and solitonic configurations are provided.

description: We investigate the dynamics of entanglement for a two-parameter class of states in a hybrid qubit-qutrit system under the influence of various dissipative channels. Our results show that entanglement sudden death (ESD) is a general phenomenon and it usually takes place in a qubit-qutrit system interacting with various noisy channels, not only the case with dephasing and depolarizing channels observed by others. ESD can only be avoided for some initially entangled states under some particular noisy channels. Moreover, the environment affects the entanglement and the coherence of the system in very different ways.

Der @Einfluss des Haptoglobin-Polymorphismus auf die Gesamtmortalität und das Auftreten kardiovaskulärer Ereignisse auf Dialysepatienten

description: Gegenstand der vorliegenden Arbeit ist es zu untersuchen, ob ein Zusammenhang zwischen dem genetisch determinierten Polymorphismus des Serumproteins Haptoglobin und der Gesamtmortalität sowie dem Auftreten kardiovaskulärer Ereignisse, wie z. B. Myokardinfarkt oder Apoplex, bei terminal niereninsuffizienten Patienten besteht. Dabei wird angenommen, dass der homozygote Haptoglobin-Typ 1 aufgrund seiner pathophysiologischen Eigenschaften einen eher positiven Effekt auf das Herzkreislaufsystem nimmt und mit einer geringeren Mortalitäts- und kardiovaskulären Ereignisrate einhergeht, als der homozygote Haptoglobin- Typ 2. Da es aktuell keine Studien gleicher Fragstellung mit ausschließlich Dialysepatienten gibt, diese aber eine deutlich höhere Mortalitäts- und kardiovaskuläre Ereignisrate aufweisen als die Allgemeinbevölkerung, entschieden wir uns zur Untersuchung dieses spezifischen Studienkollektivs. Insgesamt wurden 619 Patienten in die Auswertung einbezogen und mittels Cox-Regressionsmodell analysiert. Hinsichtlich der betrachteten Endpunkte zeigte sich kein signifikanter Zusammenhang mit dem Haptoglobin-Polymorphismus. Aus unseren statistischen Daten lässt sich schließen, dass die erhöhte Mortalitäs- und kardiovaskuläre Ereignisrate von Dialysepatienten bereits durch deren Multimorbidität und die Dialysepflichtigkeit an sich erklärt wird, wodurch ein statistisch schwächerer Effekt des Haptoglobins womöglich maskiert wird. Weitere Studien mit einem längeren Beobachtungszeitraum und einer höheren Rate an Zielereignissen wären hier wünschenswert.

description: By imposing the relativistic boundary term and Lorentz violating that in the dilatonic black brane with a Lifshitz like IR geometry and $AdS_4$ boundary, we study the properties of the spectral functions of the fermions. We find that in the two fixed points, there are emergent Fermi-surface structures and many properties seem to be in agreement with that of Fermi liquid. Especially, the low energy behavior exhibits a linear dispersion relation. In addition, we also find that a holographic flat band also emerges in this background of the dilatonic black brane.

description: A linear technique is described for the optimisation of output power and efficiency of travelling-wave amplifiers, together with guidelines for a practical computer-aided circuit design. The design procedure requires the determination of the optimum load impedances of the FET's, and the optimisation not only of the amplifier's gain and return loss, but also of the FET drains' loading.

description: Let g(t) be the minimum number such that every graph G with average degree d(G) \geq g(t) contains a K_{t}-minor. Such a function is known to exist, as originally shown by Mader. Kostochka and Thomason independently proved that g(t) \in Θ(t*sqrt{log t}). This article shows that for all fixed ε> 0 and fixed sufficiently large t \geq t(ε), if d(G) \geq (2+ε)g(t) then we can find this K_{t}-minor in linear time. This improves a previous result by Reed and Wood who gave a linear-time algorithm when d(G) \geq 2^{t-2}.

description: The possibilities and the limitations of tunable narrow band recursive active MMIC filters with respect to future adaptive on-chip radar receiv- ers are investigated. We compare the measured and he simulated results of two recursive active MMIC ilters with the corresponding theoretical results obtained using our analytical filter models. A good agreement between these results is generally found. Using our analytical filter models we also estimate the noise and intermodulation properties of the low noise amplifier used in the filters that are necessary in order to achieve a filter performance adequate for future adaptive on-chip radar receivers.

description: The article analyzes the effect of food on the pharmacotherapeutic activity of drugs. It is known, that food components (sugars, essential fatty acids, amino acids, proteins, phytosterols, minerals, vitamins, etc.) have the ability to interact with drugs and change their pharmacotherapeutic action. The aim of our study was to inves-tigate the effect of food products on drug bioavailability, to establish the relationship between changes in therapeutic activity of drugs depending on food composition and therapeutic efficacy of drugs as food effects and their interactions are not always studied and predicted, that can significantly change the quality of phar-macotherapy.

description: 77GHz PHEMT gate mixer module and resistive mixer module were fabricated for automotive applications using LG-CIT low noise PHEMT process and WR12-to-microstrip antipodal finline transitions. Experimental optimization of the finline transitions was attempted for wideband operation and low insertion loss by adjusting geometrical design parameters. The average insertion loss was measured o be 0.74dB per transition in 75~90GHz. Thefabricated gate mixer module and the resistive mixer module showed very good conversion loss of 2dB and 10.3dB, respectively, including finline transition loss and IF cable loss, which were very competitive performances.
