Layout Driven Binding In High Level Synthesis Using Reinforcement Learning. (c2021)
Authors:   ,   Lebanese American University, Melhem Marie-Claire
Published: July 2022

The increase in density that the advent of Very Large Scale Integration (VLSI) has made the move to higher levels of design abstraction imperative. High Level Synthesis (HLS) emerged as a viable approach that has been gaining strides in the EDA industry. This work exploits the tight relation that exists between the allocation process and chip layout in an integrated system level design environment. The approach proposes a layout-driven data path allocation method, and explores design tradeoffs among operators binding, registers assignments, and flooplanning shape functions. The approach uses Deep Reinforcement Learning and proposes new methods and tools for the automatic synthesis of data path at the register-transfer level (RTL). A major effort in this research involves the development of a prototype high-level synthesis system that bridges the gap between high level synthesis and layout information. The goal is to build a model capable of learning optimization steps. The approach has been implemented and several designs were implemented.
Why are Lebanese women not present in the Parliament?. (c2021)
Authors:   ,   Lebanese American University, Tannous Maria
Published: July 2022

Why are Lebanese women not present in parliament? The literature that tries to explain the low presence of Lebanese women in the parliament offers several explanations that present an academic understanding of this issue. However, after reviewing this literature, it became manifest that it does not study in depth the position of Lebanese women activists in this regard. Thus, this thesis aims to fill this methodological gap by asking Lebanese women activists about the factors that are behind the low presence of women in the Lebanese parliament. This thesis argues that without understanding their position on the matter, the literature might miss valuable input from important stakeholders on explaining why Lebanese women are not being able to reach the parliament. This thesis provides a bridge between the views of academics with those of activists following three steps. First it asks Lebanese women activists the question on what are the factors behind the low number of Lebanese women in the parliament. Then it compares their answers with what the academic literature has been saying about this topic. Finally, it will present the factors proposed by the activists that the academic literature needs to further study.
The Dilemma of the Syrian Refugees. (c2021)
Authors:   ,   Lebanese American University, Al Khomassy Maha
Published: July 2022

Syrian refugees are often perceived as threats to the Lebanese state and the Lebanese population’s welfare and security. This research argues that Syrian refugees have both positive and negative impacts on Lebanon. Moreover, it finds that Lebanese identity construction and differentiation contributes to how Syrian refugees are categorized due to several considerations. Lastly, under the rigid power sharing political structure in Lebanon, Syrian refugees could be considered threatening for some groups while in fact, it is the current political structure that should be revised to build more inclusive progressive national identity.
The Role of Domestic Politics in Explaining the Evolution of US Foreign Policy towards the Israeli-Palestinian Conflict. (c2021)
Authors:   ,   Lebanese American University, Arnous Maguy
Published: July 2022

The Deal of the Century was the latest attempt by a US president and his administration to solve one of the most protracted conflicts in the world. This thesis examines the evolution of US role in and foreign policy towards the Israeli-Palestinian conflict from the Reagan administration (1981-1989) until the end of Trump’s presidency (2020) while giving an overview of successive American peace plans to the conflict. The principal focus is to unpack the “Deal of the Century” and examine it in the lens of domestic politics. While realism helps explain certain aspects of US foreign policy towards the Israeli-Palestinian conflict – namely that a weakened Arab and Palestinian position, which no longer presents a threat to US national interests, allowed the pursuit of a more advantageous deal to the Israelis than the Palestinians – the pluralist theory helps complement our understanding of the decisions of successive US administrations towards the conflict. The thesis adds to a rich literature on the conflict and the mediator role of the US by delving into the most recent peace plan under the last administration. It also helps to lay the groundwork for an initial analysis of Biden administration’s policies towards the region, Israel and the Palestinians.

Spectral sufficient conditions of the existence of the longest path in the graph and its traceability
Authors: Benediktovich V. I.
Published: July 2022

It is known that the existence of many classical combinatorial structures in a graph, such as perfect matchings, Hamiltonian cycles, effective dominating sets, etc., can be characterized using (κ,τ)-regular sets, whose determination is equivalent to the determination of these classical combinatorial structures. On the other hand, the determination of (κ,τ)regular sets is closely related to the properties of the main spectrum of a graph. We use the previously obtained generalized properties of (κ,τ)-regular sets of graphs to develop a recognition algorithm of the traceability of a graph. We also obtained new sufficient conditions for the existence of a longest simple path in a graph in terms of the spectral radius of the adjacency matrix and the signless Laplacian of the graph.
Absorption of nonpolarized light by a two-dimensional ensemble of spherical silver particles under oblique illumination
Authors: Loiko V. A. , Miskevich A. A.
Published: July 2022

The problem of absorption of nonpolarized (natural) light by a two-dimensional ensemble (monolayer) of spherical particles under oblique illumination is considered. The solution is based on the statistical theory of multiple scatteing of waves. The written equations make it possible to find the optimal conditions for the absorption of directed light to increase the absorption efficiency of monolayers with a periodic and partially ordered spatial arrangement of particles. The results of the calculations are presented for the absorption coefficient of polarized and natural light by ensembles of silver particles in a nonabsorbing medium. The particle size and monolayer filling factor are chosen so as to illustrate the dependence of absorption on the angle of incidence under conditions of resonance effects caused by the spatial organization of particles. It is shown that in the region of the resonant absorption peak a normally illuminated monolayer with a triangular lattice of silver particles can absorb almost an order of magnitude more incident light than a partially ordered layer. The absorption coefficient of a monolayer under directional oblique illumination can be almost an order of magnitude larger than under normal illumination. The results can be used to optimize the design of opto-electronic devices based on particulate layers.

Published: July 2022

The effect of gain saturation in quantum-cascade structures with 2–4 quantum wells per period is herein analyzed on the basis of a system of balance equations. It is shown that the nonlinearity parameter decreases with an increase in the relaxation rate of laser levels, but the total current through the structure also increases. The use of the proposed multiphoton designs leads to a decrease in the non-linearity parameter without increasing the operating current. For example, in a two-photon scheme of laser transitions with the same transition probabilities and differential gains, two times slower saturation of the gain with an increase in the photon density is achieved, which leads to a high generation efficiency than in single-photon schemes.

Published: July 2022

The container structures consisting of the core made of layered molybdenum oxide intercalated with 3-amono-1,2,4-triazole (it behaves as the corrosion inhibitor) capped with the shell made of polymerized tungsten oxide were synthesized employing the polycondensation of oxocompounds. It is shown that in the acid (pH < 5.5) and alkali (pH > 8.5) media, the coating continuity appears to be broken reversibly, which facilitates the emission of the encapsulated compounds from the containers. The intrinsic redox activity inherent into the oligooxometalate shell permits one to immobilize the synthesized containers by co-precipitation with galvanic nickel, whereas the possibility to open the container as a result of local pH value variations accompanying the corrosion process ensures the autonomic corrosion protection of the resultant metal-matrix coatings.

The processes of mechanochemical reduction of oxides of iron, nickel, and copper with aluminum with a stoichio metric ratio of components and in mixtures with a two-, three-, and four-fold excess of the aluminum content over the stoichiometric, as well as in the presence of an excess of oxide-forming metal and solid solutions of aluminum in iron and copper, were studied by the Mössbauer and IR spectroscopy, X-ray diffraction analysis, including the use of synchrotron radiation, and electron microscopy. The conditions for formation of metals modified with aluminum oxide (iron, nickel, copper) and their monoaluminides are determined. High aluminum content aluminides are formed at a three-fold excess of aluminum, and at a four-fold excess, a mechanochemical reduction of oxides does not occur. The preferred method for modifying metals with alumina is the mechanochemical reduction of oxides with a solid solution of aluminum in the oxideforming metal. Mechanochemical interaction in the high-energy Hf–C system in the presence of 20, 30, and 50 wt. % copper leads to the formation of hafnium carbide; and with an increase in the copper content, the crystallite size decreases.
Production of nano- and micropowders of cubic BN from mechanically activated graphite-like BN under high pressures and temperatures using aluminium as a phase convertion initiator
Authors: Senyut V. T.
Published: July 2022

An effect of mechanical activation of graphite-like (hexagonal) boron nitride (hBN) on catalytic synthesis of nano- and micropowders of cubic boron nitride (cBN) under conditions of high pressures and temperatures is shown in the article. It has been suggested that nuclei of dense phases of boron nitride (cubic and wurtzite) are formed in the hBN structure during mechanical activation they serve as crystallization centers stimulating the formation of cBN crystals under subsequent thermobaric treatment. Additional chemical-thermal modification of hBN with aluminum as a catalyst (initiator) for the phase transformation of hBN into cBN leads to a significant increase in the content of cBN along with an increase in the synthesis pressure. Thus, the introduction of Al additives in the amount of 10 wt.% leads to an increase in the content of the cBN phase from 10–15 % under synthesis pressure of 2.5 GPa up to 90 % under pressure of 5.5 GPa. In this case, the grain size of cBN, estimated by scanning and atomic force microscopy, is mainly 200–400 nm and 40–120 nm for the samples synthesized under pressure of 2.5 and 5.5 GPa, respectively. The increase in the content of the initiator from 10 to 40 wt.% with an increase in isothermal holding time from 15 to 60 s in the studied range of pressures and temperatures leads to the formation of intergrowths of cBN grains in nano- and submicron sizes and individual cBN single crystals of a cubic habit with a grain size of 1–4 µm, as well as polycrystalline cBN particles from 10 to 50 µm. In this case, the maximum size distribution of cBN micropowders in the range up to 50 µm falls on particles up to 5 µm (~ 70 %). In the submicron grain size range the maximum yield (~ 50 %) is marked for cBN particles 0.5–0.7 µm in size. The obtained powders can be used to make abrasive and cutting tools.
Peculiarities of hardening of steel – copper alloy pseudo-alloys obtained by infiltration during hot plastic deformation
Authors: Dyachkova L. N.
Published: July 2022

The influence of the regimes of plastic deformation of steel – copper alloy pseudo-alloys obtained by infiltration on their structure, mechanical properties and anisotropy of properties is investigated. It has been established that hot forging of pseudo-alloys at a temperature of 700–950 °C provides an increase in strength by 1.5–3 times, impact strength by 1.5–2.5 times, plasticity by 1.5–2 %, and at 1100–1150 °С (above the melting point of copper) – leads to cracking of the material. It is shown that the properties of pseudo-alloys based on steel alloyed with chromium are lower than those based on steel alloyed with nickel, which is associated with the formation of chromium oxides due to its increased affinity for oxygen. The formation of macro-texture in pseudo-alloys after hot stamping has been established, which leads to secondary anisotropy of properties, the level of which is determined by the degree of deformation and temperature, but does not exceed 15–20 %. The deformation curve of the pseudo-alloy during hot forging was constructed, which revealed the optimum temperature (700–900 °С) and the limiting degree of deformation (65 %) depending on the composition of the pseudo-alloy. With an increase in the degree of deformation, microcracks form at the interface between the iron and copper phases, which in turn leads to a decrease in strength, ductility, as well as a 1.5–2-fold decrease in the impact strength of pseudo-alloys with a copper phase content of 15 % and destruction of pseudo-alloys with a 25 % copper content phases, in which the length of interphase iron-copper boundaries is much greater. The achieved mechanical properties of hot-forged steel-copper alloy pseudo-alloys make it possible to use them for parts of heavily loaded friction units, as well as parts for structural purposes.
Study of the characteristics of germanium avalanche photodiodes in the photon counting mode
Authors: Gulakov I. R. , Zenevich A. O. , Kochergina O. V. , Matkovskaia T. A.
Published: July 2022

A study was made of the characteristics of photodetectors for fiber-optic communication lines using quantum cryptographic systems – germanium avalanche photodiodes operating in the photon counting mode. In particular, it was established at what highest temperature the implementation of the photon counting mode is possible, and the influence of temperature and overvoltage on the sensitivity of photodiodes is also considered. An experimental setup has been developed for the research. It has been determined that the highest ambient temperature at which LFD-2 germanium avalanche photodiodes operate in the photon counting mode is 243 K. It has also been found that the highest sensitivity of germanium avalanche photodiodes corresponds to the optical radiation wavelength range of 1310÷1490 nm. Lowering the temperature leads to an increase in the sensitivity of germanium avalanche photodiodes. It was found that the dependence of the signal-to-noise ratio on overvoltage has a maximum corresponding to overvoltage ΔU = 0.1 V. Lowering the temperature led to an increase in sensitivity and signal-to-noise ratio. Since there was no shift in the maximum dependence of the signal-to-noise ratio on the overvoltage, it was therefore concluded that when the avalanche photodiode operates in the photon counting mode, in order to ensure maximum sensitivity, it is necessary to select the overvoltage corresponding to the maximum signal-to-noise ratio. The results obtained can be used in quantum cryptographic systems, technical means of protecting information transmitted over fiber-optic communication lines, and for the metrology of single-photon radiation sources.

The health care system in Great Britain is considered, as well as the economic effectiveness of its functioning in comparison with the major European countries and Belarus. We considered the institutional features of its modern improvement, and made an attempt to measure the effectiveness of innovations in the healthcare system. Cost-effectiveness, its content, indicators and influencing factors have been sufficiently studied in the Russian literature. However, little attention is paid to the specificity of indicators that related to the non-productive sphere, especially the effectiveness of institutional reforms in it and to the regulative role of the state. The health care system аs any makes the greatest contribution to the preservation and increase of human capital, so it has every right to be considered a second-level production sphere, where is formed the most important factor of social production. A comparative analysis of the effectiveness of institutional and legal changes in the healthcare system of the leading countries allows us to identify the horizons of the strategic health policy in Belarus.

Background: TREAT-NMD is a global neuromuscular (NM) organization, created to enhance infrastructure to facilitate novel therapeutics reaching patients. One main activity is aimed at supporting NM disease registries. These rare disease registries are useful to fill knowledge gaps for various stakeholders in the disease community using real world data. Although it is important to understand how patient data is being utilized in the TREAT-NMD network and other rare disease registries, there is no systematic process or consistent metric for documenting the academic output from these registries. Objectives: The objective of this study was to determine the academic output from NM registries associated with the TREAT-NMD network, and the types of research the data is facilitating. Results: A systematic search of EMBASE, Medline, Cochrane Central and SCOPUS was performed from inception to November 24, 2021. The search yielded a total of 650 results, with 231 full text studies assessed for eligibility and a total of 97 studies that met the inclusion criteria. Conclusions: The results suggest publications from TREAT-NMD are mainly descriptive or methodologic. Rare disease registries, like the TREAT-NMD network, would benefit from clear and consistent metrics to facilitate reporting of academic output.

In recent years, there has been a positive trend in coffee consumption in Indonesia. Dringking coffee which were originally identical as oldmans drinks, is starting to be liked by teenagers to children. This is because coffee contains caffeine which can have an addictive effect. Drinking coffee in the right dose can have positive effects for the drinker, such as stimulating the ability of brain function and also as an antioxidant. However, if you drink more coffee than your body can tolerate, it will cause symptoms of insomnia, excessive anxiety and increased blood pressure. Various attempts have been made to reduce the caffeine content in coffee (decaffeination), one of which is by mixing coffee with chayote juice (Sechium edule) as has been done by Paramartha (2021). Furthermore, this article classifies the characteristics of decaffeinated products, caffeine content, moisture content, total acid content of titration, ash content, hue color, and L value. By using factor analysis, it is known that the characteristics can be mapped into three main factors, where the first main factor consists of variables of caffeine content, water content, and hue color value. The second main factor consists of variables of ash content, and total acid content titration, and the third major factor, this factor consists only of the characteristic L. It is also known that 74.2% of the diversity of origin can be explained by the three main factors.

The performance study tested four microphysics schemes viz., Kessler, WSM3, WSM5 and WSM6 for all the four seasons of 2020. The results obtained for the Southern Zone (SZ) is discussed in this paper and study concluded that the performance of high resolution village level (3km) rainfall forecast at Southern Agro Climatic Zone of Tamil Nadu generated from WRFv4.2.1 model was best with the WSM3 microphysics scheme followed by Kessler scheme, WSM5 and WSM6. Between the major rainfall seasons, Forecast Accuracy Index (FAI) was higher in NEM (0.56 to 0.73) than SWM (0.38 to 0.70), whereas the Forecast Usability Percent (FUP) was almost similar during both the South West Monsoon (SWM, 53.0 to 81.4) and North East Monsoon (NEM, 52.9 to 85.9). There was overestimation observed irrespective of season and microphysics options.

Introducción: El propofol es uno de los agentes hipnóticos más utilizados en anestesia para procedimientos quirúrgicos debido a su inicio y reversión rápida, con gran importancia actualmente en las unidades de cuidado crítico para sedación dada la posibilidad de taquifilaxia en este tipo de pacientes. A pesar de tener un adecuado perfil de seguridad, existe relación directa entre dosis altas (>4mg/kg/hora) y prolongadas (>48 horas) con el Síndrome de Infusión de Propofol, una afección poco común y potencialmente mortal caracterizado primordialmente por acidosis metabólica, alteraciones cardiovasculares, rabdomiolisis e hiperkalemia. La incidencia de esta complicación se encuentra alrededor del 1.1%. El objetivo es realizar una revisión bibliográfica sobre el síndrome por infusión de propofol presentando la importancia de la prevención, diagnóstico y manejo de esta entidad con sus implicaciones en las unidades de cuidado intensivo. Material y métodos: Se realizó una búsqueda de la literatura en las bases de datos de PubMed y Scielo de artículos actualizados y relevantes en inglés o español presentando la importancia de la prevención, diagnóstico y manejo farmacológico. Conclusión. El Síndrome Infusión de Propofol es una complicación rara con alta mortalidad por lo cual se debe establecer estrategias y protocolos intrahospitalarios destinados al manejo inmediato en casos de sospecha o diagnóstico de manera oportuna.

Os estudos sobre a paisagem, sob o viés sistêmico, integrado e geoecológico é fundamental para alcançar o zoneamento ambiental, pois permitem compartimentar a área em unidades geossistêmicas, e propiciar propostas diante de suas fragilidades, potencialidades e funcionalidades. Logo, a pesquisa adotou a Bacia Hidrográfica do Rio Mimoso, localizada no município de Bonito/MS, como área de estudo para elaborar um zoneamento ambiental, a fim de oferecer suporte para um ordenamento físico-territorial. Para tanto, foram utilizadas técnicas e ferramentas ligadas ao Sistemas de Informação Geografica ArcGis 10® e Spring 5.2.6, bem como saídas de campo para análise das águas superficiais e verificação dos dados com a realidade terrestre. Nota-se que essa bacia é ligada ao ambiente cárstico, com águas translúcidas e agropecuária marcante. Mesmo que apresente áreas de vegetação preservada, é uma bacia que vem padecendo sob constantes pressões sobre os recursos hídricos, e com isso, o zoneamento ambiental possibilitou identificar extensas áreas com necessidades de recuperação devido à incongruências legais e ambientais. Na conclusão foram elaboradas propostas para um (re)ordenamento de uso das terras, reduzindo as mazelas sobre o contexto ambiental da bacia.
