Theoretical Study of Solvent Effects on the Platinum-Catalyzed Oxygen Reduction Reaction [PDF]
, 2010 We report here density functional theory (DFT) studies (PBE) of the reaction intermediates and barriers involved in the oxygen reduction reaction (ORR) on a platinum fuel cell catalyst.

The volume of an isolated singularity
, 2011 We introduce a notion of volume of a normal isolated singularity that generalizes Wahl's characteristic number of surface singularities to arbitrary dimensions. We prove a basic monotonicity property of this volume under finite morphisms. We draw several

Double factorization of the Jonsson spectrum
Қарағанды университетінің хабаршысы. Математика сериясыFirst of all, we have to note that in this article, we introduced the new concepts of relations between Jonsson theories in the class of cosemanticness for some considered Jonsson spectrum.

On the independence complex of square grids
, 2007 The enumeration of independent sets of regular graphs is of interest in statistical mechanics, as it corresponds to the solution of hard-particle models. In 2004, it was conjectured by Fendleyet al.

Valuations and plurisubharmonic singularities
, 2007 We extend to higher dimensions some of the valuative analysis of singularities of plurisubharmonic (psh) functions developed by the last two authors. Following Kontsevich and Soibelman we describe the geometry of the space V of all normalized valuations ...

Random paths with curvature [PDF]
, 1996 We present some results coming from a Monte Carlo simulation of a set of random paths with a curvature dependent action. This model can be considered as a toy model of the theory of random surfaces. The transition from free to rigid random paths has been

The properties of central-orbital types of EPSCJ theories
Қарағанды университетінің хабаршысы. Математика сериясы, 2017 This article, in its content, refers to the study of the theoretical - model properties of the Jonsson theories. A new approach to this study is proposed. As a new notion, the idea of a central - orbital type is used.

Solution of Supplee's submarine paradox through special and general relativity
, 2016 In 1989 Supplee described an apparent relativistic paradox on which a submarine seems to sink to observers at rest within the ocean, but it rather seems to float in the submarine proper frame. In this letter, we show that the paradox arises from a misuse

Criterion for the cosemanticness of the Abelian groups in the enriched signature
Қарағанды университетінің хабаршысы. Математика сериясы, 2018 In the present paper we give a criterion of the cosemanticness relative to the Jonsson spectrum of the model in the class of Abelian groups with a distinguished predicate.

Random tree growth by vertex splitting
, 2009 We study a model of growing planar tree graphs where in each time step we separate the tree into two components by splitting a vertex and then connect the two pieces by inserting a new link between the daughter vertices.
