Analysis on Stochastic Anisotropic Degenerate Parabolic-Hyperbolic Mixed-Type Equations

open access: yes, 2017
This dissertation consists chiefly of three parts, which tell different facets in the development of one topic. The first part is an exploration of continuous dependence estimates of stochastically driven degenerate parabolic equations.

Inner boundary value problem with displacement for a second order mixed parabolic-hyperbolic equation

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2022
This paper investigates inner boundary value problems with a shift for a second-order mixed-hyperbolic equation consisting of a wave operator in one part of the domain and a degenerate hyperbolic operator of the first kind in the other part.

A boundary value problem for the fourth-order degenerate equation of the mixed type

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы
Many problems in mechanics, physics, and geophysics lead to solving partial differential equations that are not included in the known classes of elliptic, parabolic or hyperbolic equations.

An energy analysis of degenerate hyperbolic partial differential equations. [PDF]

open access: yesApplications of Mathematics, 1984
From author's summary: An energy analysis is carried out for the usual semi-discrete Galerkin method for the semilinear equation in the region \(\Omega\) : \((tu_ t)_ t=\sum_{i,j=1}(a_{ij}(x)u_{x_ i})x_ i- a_ 0(x)u+f(u),\) subject to the initial and boundary conditions, \(u=0\) on \(\partial \Omega\) and \(u(x,0)=u_ 0\).

Problems of optimal and hard control over solutions of special type of nonstationary Sobolev type equations

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2014
Sobolev type equations now constitute a vast area of nonclassical equations of mathematical physics. Those called nonclassical equations of mathematical physics, whose representation in the form of equations or systems of equations partial does not fit ...

Mixed Problems for Singular and Degenerate Hyperbolic Equations

open access: yesPublications of the Research Institute for Mathematical Sciences, 1987
The author considers a mixed problem for a degenerate hyperbolic equation with principal symbol \(\prod^ m_{j=1}(\tau-t^ k\Lambda_ j(t,x,y;\xi,\eta))\), where \(k\) is a real number, \(k>0\), the variables \((\xi,\eta)\) are dual to \((x,y)\), and the \(\Lambda^ j(t,x,y;\xi,\eta)\) are real and distinct. For this problem the author proves existence and

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

On a class of nonlocal problems for hyperbolic equations with degeneration of type and order

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2014
Nonlocal problems for the second order hyperbolic model equation were studied in the characteristic area. The type and order of equations degenerate on the same line $y = 0$.

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

open access: yesFEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.
