Some methods for solving boundary value problems for polyharmonic equations

Қарағанды университетінің хабаршысы. Математика сериясы
This article consists of three sections. In the first section the concept of Vekua space is introduced, where for elliptic systems of the first order, the theorem on the representation of the solution of a homogeneous equation and the theorem on the ...

Efficient implementation of geometric integrators for separable Hamiltonian problems

, 2013
We here investigate the efficient implementation of the energy-conserving methods named Hamiltonian Boundary Value Methods (HBVMs) recently introduced for the numerical solution of Hamiltonian problems.

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Application of statistical methods for solving problems of construction materials science

Нанотехнологии в строительстве, 2020
In the areas of construction materials science, the most promising solution is a set of issues related to the study of the influence of conditions for the formation of the material structure, including the possibilities of its self-organization, on its ...

Applicability of mitotic figure counting by deep learning: a development and pan‐cancer validation study

FEBS Open Bio, EarlyView.
In this study, we developed a deep learning method for mitotic figure counting in H&E‐stained whole‐slide images and evaluated its prognostic impact in 13 external validation cohorts from seven different cancer types. Patients with more mitotic figures per mm2 had significantly worse patient outcome in all the studied cancer types except colorectal ...

TRAVEL OF A CIRCLE IN A TRIANGLE, AND THE TRIANGLE IN THE HOLLOW OR SELF COMPUTER DIRECTOR

Открытое образование (Москва), 2016
The article describes an unusual possibility to use animation to study numerical methods for solving mathematical problems. Animation is defi ned not only and not so much as the creation of animation clips, but direct «revival» of the results of the ...

Reducing statistical time-series problems to binary classification [PDF]

, 2012
We show how binary classification methods developed to work on i.i.d. data can be used for solving statistical problems that are seemingly unrelated to classification and concern highly-dependent time series.

The Shooting Method for Solving Eigenvalue Problems

Journal of Mathematical Analysis and Applications, 1996
The generalized eigenvalue problem \({d^2R\over dv^2}=Q(v,\lambda)R\), \(v\in (-\infty,\infty)\), \(\lambda\in [a,b]\) under a boundedness condition is considered. The main results concern a characterization of the eigenvalues. Let \(Z(\lambda)\) be the number of zeros of a solution bounded on \((0,\infty)\) for \(\lambda\in [a,b]\).

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

FEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...
