Abstract—The multipletrapping model with a Gaussian trap distribution was used for the numerical analysis of the effects of nonequilibrium transport on the temperature dependence and field dependence of the mobility of carriers in a typical molecularly doped polymer. It was shown that, with allowance for the prescribed Poole–Frenkel Frenkel type field dependence of mobility under the conditions of nonequilibrium transport, the observed decrease in the effective energy of disorder may be explained as a compensation effect with no change in the initial energy distribution of hopping centers.

A theoretical analysis of the peculiarities of the nonlinear field dependence of radiation-pulse conductivity of polystyrene in strong electric fields. The explanation of previously misunderstood the rapid increase of the radiation conductivity in electric fields, the intensity of which exceeds 5E7 V/m. this behavior cannot be explained on the basis of the Onsager theory for thermo-energy generating free charges generated from genialnyh pairs.

Loop groups, Clusters, Dimers and Integrable systems

Marshakov A., Fock V. arxiv.org. math. Cornell University, 2014

We describe a class of integrable systems on Poisson submanifolds of the affine Poisson-Lie groups PGLˆ(N), which can be enumerated by cyclically irreducible elements the co-extended affine Weyl groups (Wˆ×Wˆ)♯. Their phase spaces admit cluster coordinates, whereas the integrals of motion are cluster functions. We show, that this class of integrable systems coincides with the constructed by Goncharov and Kenyon out of dimer models on a two-dimensional torus and classified by the Newton polygons. We construct the correspondence between the Weyl group elements and polygons, demonstrating that each particular integrable model admits infinitely many realisations on the Poisson-Lie groups. We also discuss the particular examples, including the relativistic Toda chains and the Schwartz-Ovsienko-Tabachnikov pentagram map.

Dynamics of the Davydov-Scott soliton with location or velocity mismatch of its high-frequency component

Blyakhman L. G., Gromov E., Onosova I. V. et al. Physics Letters A. 2017. Vol. 381. No. 17. P. 1490-1492.

The dynamics of a two-component Davydov-Scott (DS) soliton with a small mismatch of the initial location or velocity of the high-frequency (HF) component was investigated within the framework of the Zakharov-type system of two coupled equations for the HF and low-frequency (LF) fields. In this system, the HF field is described by the linear Schrödinger equation with the potential generated by the LF component varying in time and space. The LF component in this system is described by the Korteweg-de Vries equation with a term of quadratic influence of the HF field on the LF field. The frequency of the DS soliton`s component oscillation was found analytically using the balance equation. The perturbed DS soliton was shown to be stable. The analytical results were confirmed by numerical simulations.

On the Richardson extrapolation in time of finite element method with discrete TBCs for the Cauchy problem for the 1D Schrödinger equation

Zlotnik Alexander, Zlotnik Ilya. arxiv.org. math. Cornell University, 2014. No. arXiv:1405.3147.

We consider the Cauchy problem for the 1D generalized Schrödinger equation on the whole axis. To solve it, any order finite element in space and the Crank-Nicolson in time method with the discrete transpa\-rent boundary conditions (TBCs) has recently been constructed. Now we engage the Richardson extrapolation to improve significantly the accuracy in time step. To study its properties, we give results of numerical experiments and enlarged practical error analysis for three typical examples. The resulting method is able to provide high precision results in the uniform norm for reasonable computational costs that is unreachable by more common 2nd order methods in either space or time step. Comparing our results to the previous ones, we obtain much more accurate results using much less amount of both elements and time steps.

Исследование баротропной квазигидродинамической модели двухфазной смеси с учетом поверхностных эффектов

Балашов В. А., Злотник А.А., Савенков Е. Б. Институт прикладной математики им. М.В. Келдыша Российской академии наук, 2016. № 89.

A study of the barotropic quasi-hydrodynamic system of equations for the two-phase two-component mixture involving the surface tension and stationary potential force is accomplished. Under fairly general assumptions on the Helmholtz free energy of the mixture, the~energy balance equation with non-positive energy production together with its corollary, the law of non-increasing total energy, are derived; in particular, both the isothermal and isentropic cases are covered. Under additional assumptions, the necessary and sufficient conditions for the linearized stability of constant solutions are derived (it does not take place always). A finite-difference approximation of the problem is constructed in the 2D periodic case for a non-uniform rectangular mesh. Approximation of the capillary stress tensor is improved in the momentum balance equation thus increasing the quality of numerical solutions. The results of numerical experiments are presented. They demonstrate the ability of the model to ensure the qualitatively correct description for the dynamics of surface effects as well as applicability of the linearized stability criterion in the original nonlinear statement.

Public sector e-innovations. E-government and its impact on corruption

Proskuryakova L. N., Abdrakhmanova G., Pitlik H. Science, Technology and Innovation. WP BRP. Высшая школа экономики, 2013. No. 04/STI/2013.

The paper aims at assessing indicators and individual elements of e-government of selected countries in 2009-2010, and the interrelation of e-government with corruption in the public sector. The authors explore possible causal and dependency relations of the established interlink between e-government and public sector corruption. Although it is universally acknowledged that corruption is an evil, there is much debate over which determinants of corruption are important. Using econometric analysis for sizeable country samples the authors verified the closeness of interrelation between e-government indicators and ICT Development Index indicators, such as online services quality and ICT usage, on one hand, and the level of perceived public sector corruption, on the other hand. The major research papers were analyzed, along with international rankings and databases of international organizations. Based on the analysis recommendations for overcoming international e-government measurement constraints are put forward, as well as suggestions for future studies of the topic.

Equal Weights Coauthorship Sharing and Shapley Value are Equivalent

Karpov A. V. Science, Technology and Innovation. WP BRP. Высшая школа экономики, 2012. No. 03.

The publication credit allocation problem is one of the fundamental problems in bibliometrics. The solution of this problem provides the basis of further research. There are two solutions which do not require any additional information: equal weights measure and Shapley value. Until recently Shapley value is not used because of hardness of computing. The paper justifies the equal weights measure by showing equivalence with the Shapley value approach for sharing coauthors performance in specific games.

The paper provides a number of proposed draft operational guidelines for technology measurement and includes a number of tentative technology definitions to be used for statistical purposes, principles for identification and classification of potentially growing technology areas, suggestions on the survey strategies and indicators. These are the key components of an internationally harmonized framework for collecting and interpreting technology data that would need to be further developed through a broader consultation process. A summary of definitions of technology already available in OECD manuals and the stocktaking results are provided in the Annex section.
