A mathematical analysis of SELEX [PDF]

open access: yesComputational Biology and Chemistry, 2007
Systematic evolution of ligands by exponential enrichment (SELEX) is a procedure by which a mixture of nucleic acids that vary in sequence can be separated into pure components with the goal of isolating those with specific biochemical activities. The basic idea is to combine the mixture with a specific target molecule and then separate the target-NA ...

Extreme problems in the space of meromorphic functions of finite order in the half plane. II

open access: yesМатематичні Студії, 2020
The extremal problems in the space of meromorphic functions of order $\rho>0$ in upper half-plane are studed. The method for studying is based on the theory of Fourier coefficients of meromorphic functions.

Modelling line edge roughness in periodic line-space structures by Fourier optics to improve scatterometry [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2014
In the present paper, we propose a 2D-Fourier transform method as a simple and efficient algorithm for stochastical and numerical studies to investigate the systematic impacts of line edge roughness on light diffraction pattern of periodic line-space ...

Disentangling the Information in Species Interaction Networks

open access: yesEntropy, 2021
Shannon’s entropy measure is a popular means for quantifying ecological diversity. We explore how one can use information-theoretic measures (that are often called indices in ecology) on joint ensembles to study the diversity of species interaction ...

Analytic Resolving Families for Equations with the Dzhrbashyan–Nersesyan Fractional Derivative

open access: yesFractal and Fractional, 2022
In this paper, a criterion for generating an analytic family of operators, which resolves a linear equation solved with respect to the Dzhrbashyan–Nersesyan fractional derivative, via a linear closed operator is obtained.

Mathematical Analysis of Chemical Reaction Systems [PDF]

open access: yes, 2018
The use of mathematical methods for the analysis of chemical reaction systems has a very long history, and involves many types of models: deterministic versus stochastic, continuous versus discrete, and homogeneous versus spatially distributed.

Mathematical Analysis of Ultrafast Ultrasound Imaging [PDF]

open access: yesSIAM Journal on Applied Mathematics, 2016
This paper provides a mathematical analysis of ultrafast ultrasound imaging. This newly emerging modality for biomedical imaging uses plane waves instead of focused waves in order to achieve very high frame rates.
