Towards Innovative Healthcare Grid Solutions: ViroLab - A Virtual Laboratory for Infectious Diseases
With more rare and critical diseases, medical diagnoses and disease prevention constitutes one of the challenging and at the same time most difficult fields in modern health care. Using interdisciplinary approaches where different areas of research such as biology, chemistry, mathematics, and computer science meet together in order to analyze, understand and reconstruct complex medical processes, those projects typically achieve excellent research results but are inefficient and unfeasible for daily medical workflows. The EU funded project ViroLab should address this important issue by combining different scientists together into one project in order to design and develop a working platform for researchers and especially for doctors, which facilitates medical knowledge discovery and decision support for HIV drug resistance for daily clinical usage. In this paper, we will present the overall concept of the ViroLab project. The core functionalities will be described in detail and shall give the readers an idea of an innovative system for disease prevention, diagnosis and treatment based on integrated biomedical data and information on several levels
Asymmetric Gepner Models II. Heterotic Weight Lifting
A systematic study of "lifted" Gepner models is presented. Lifted Gepner
models are obtained from standard Gepner models by replacing one of the N=2
building blocks and the factor by a modular isomorphic model on the
bosonic side of the heterotic string. The main result is that after this change
three family models occur abundantly, in sharp contrast to ordinary Gepner
models. In particular, more than 250 new and unrelated moduli spaces of three
family models are identified. We discuss the occurrence of fractionally charged
particles in these spectra.Comment: 46 pages, 17 figure
Large N Free Energy of 3d N=4 SCFTs and AdS/CFT
We provide a non-trivial check of the AdS_4/CFT_3 correspondence recently
proposed in arXiv:1106.4253 by verifying the GKPW relation in the large N
limit. The CFT free energy is obtained from the previous works
(arXiv:1105.2551, arXiv:1105.4390) on the S^3 partition function for
3-dimensional N=4 SCFT T[SU(N)]. This is matched with the computation of the
type IIB action on the corresponding gravity background. We unexpectedly find
that the leading behavior of the free energy at large N is 1/2 N^2 ln N. We
also extend our results to richer theories and argue that 1/2 N^2 ln N is the
maximal free energy at large N in this class of gauge theories.Comment: 20 pages, 3 figure
Application of Compensation Algorithms to Control the Movement of a Robot Manipulator
This article presents an application-oriented method for the structural synthesis of control systems for multichannel linear objects. It provides a general form, based on the compensation for object dynamics and disturbances. The algorithm is based onalgebraic transformations of the mathematical model of the object and reference systems. The
general procedure for the synthesis of a control algorithm is presented by the example of a SISO first-order object. Parametric robustness and correspondence of the system behavior to its own reference filters were derived. The possibility of applying this method to control non-linear objects presented in the form of "State Dependent coefficient (SDC)" is ascertained. A simplified example is given by the synthesis of the motion control of a one-link manipulator with a drive, described by a second-order nonlinear equation. Control of a two-link manipulator represented by its linearized equation is demonstrated. The
convenience of the proposed synthesis method for controlling multi-channel objects under certain simplifications allowed by the specifics of the use of objects is shown. The
numerical example shows the independence of the system through individual channels, a zero static error in all the modes of operation and the correspondence of the system
behavior to given dynamics

ОСОБЕННОСТИ СОВРЕМЕННОЙ ОБРАЗОВАТЕЛЬНОЙ МИГРАЦИИ В СТРАНАХ ТАМОЖЕННОГО СОЮЗА
The article describes the types of student migration and methodological approaches to its study. The global trends in educational migration and the development of this process in Belarus in the period 1999–2014 are analyzed. The countries of origin are highlighted, and factors that contribute to attracting educational migrants to the Republic of Belarus are indicated. One of the characteristic trends in the development of the modern education system is the rapid growth of student migration throughout the twentieth century. The scale of academic mobility and academic migration has steadily increased throughout the world. But it was at the turn of the XX and XXI centuries. this type of mobility is becoming a massive global phenomenon.
The Republic of Belarus clearly demonstrates the growing student mobility: there is an increase in both incoming and outgoing educational migration. In the period from 1999 to 2013 the rate of outgoing student mobility has increased by more than 5 times. The growth rate of incoming mobility is not as significant. The number of arriving school migrants is increasing year by year, but the rate of growth of incoming mobility over the past 8 years has been declining. From 2005 to 2014 In Belarus, more than 100 thousand foreign students were educated. In 2016, 100 thousand Kazakhstanis studied at foreign universities. In the 2018-2019 academic year, the number of foreign students has reached 23 thousand people, by 2020 it is planned to increase their number to 50 thousand people. For three years in a row, Russia has been accepting 15,000 foreigners for free tuition at several hundred universities in the country in 659 different areas and specialties. The British company QS recently placed Russia on the 26th place in the world for the quality of the higher education system. In 2016, the competition among foreigners was 4.5 people per Russian budget place, reports Rossotrudnichestvo.El artículo describe los tipos de migración estudiantil y los enfoques metodológicos para su estudio.

Республика Беларусь наглядно демонстрирует растущую мобильность студентов: увеличивается как входящая, так и исходящая образовательная миграция. За период с 1999 по 2013 год показатель исходящей мобильности студентов увеличился более чем в 5 раз. Темпы роста въездной мобильности не столь значительны. Число прибывающих школьных мигрантов растет из года в год, но темпы роста въездной мобильности за последние 8 лет снижаются. С 2005 по 2014 год в Беларуси обучалось более 100 тысяч иностранных студентов. В 2016 году в зарубежных вузах обучалось 100 тыс. жителей Казахстана. В 2018-2019 учебном году численность иностранных студентов достигла 23 тыс. человек, к 2020 году планируется увеличить их численность до 50 тыс. человек. В течение трех лет подряд Россия принимает 15 000 иностранцев для бесплатного обучения в нескольких сотнях университетов страны по 659 различным направлениям и специальностям. Британская компания QS недавно поставила Россию на 26-е место в мире по качеству системы высшего образования. В 2016 году конкурс среди иностранцев составил 4,5 человека на одно бюджетное место в России, сообщает Россотрудничество
Towards Deconstruction of the Type D (2,0) Theory
We propose a four-dimensional supersymmetric theory that deconstructs, in a
particular limit, the six-dimensional theory of type . This 4d
theory is defined by a necklace quiver with alternating gauge nodes
and . We test this proposal by comparing the
6d half-BPS index to the Higgs branch Hilbert series of the 4d theory. In the
process, we overcome several technical difficulties, such as Hilbert series
calculations for non-complete intersections, and the choice of
versus gauge groups. Consistently, the result matches the Coulomb
branch formula for the mirror theory upon reduction to 3d
Localization of supersymmetric field theories on non-compact hyperbolic three-manifolds
We study supersymmetric gauge theories with an R-symmetry, defined on
non-compact, hyperbolic, Riemannian three-manifolds, focusing on the case of a
supersymmetry-preserving quotient of Euclidean AdS. We compute the exact
partition function in these theories, using the method of localization, thus
reducing the problem to the computation of one-loop determinants around a
supersymmetric locus. We evaluate the one-loop determinants employing three
different techniques: an index theorem, the method of pairing of eigenvalues,
and the heat kernel method. Along the way, we discuss aspects of supersymmetry
in manifolds with a conformal boundary, including supersymmetric actions and
boundary conditions.Comment: v3:79p, minor clarifications and references adde
