Improved gravitation field algorithm and its application in hierarchical clustering. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND: Gravitation field algorithm (GFA) is a new optimization algorithm which is based on an imitation of natural phenomena. GFA can do well both for searching global minimum and multi-minima in computational biology.

On one approximate method for recovering a function from its autocorrelation function

open access: yesИзвестия высших учебных заведений. Поволжский регион: Физико-математические науки, 2022
Background. When solving many physical and technical problems, a situation arises when only operators (functionals) from the objects under study (signals, images, etc.) are available for observations (measurements). It is required to restore the object

Multiscale Modeling in Systems Biology: Methods and Perspectives

open access: yesDigital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology, 2021
In the last decades, mathematical and computational models have become ubiquitous to the field of systems biology. Specifically, the multiscale nature of biological processes makes the design and simulation of such models challenging.

A new multi-offspring crossover operator for genetic algorithm to facilitate the traveling salesman problem [PDF]

open access: yesComputer Science Journal of Moldova, 2019
This research work provides a detailed working principle and official analysis of a multi-offspring crossover operator. The proposed operator explains the true theory of survival-of-fittest using the foundation of evolutionary theories of biology and ...

Higher-Order Multiplicative Derivative Iterative Scheme to Solve the Nonlinear Problems

open access: yesMathematical and Computational Applications, 2023
Grossman and Katz (five decades ago) suggested a new definition of differential and integral calculus which utilizes the multiplicative and division operator as compared to addition and subtraction.

Selection of key sequence-based features for prediction of essential genes in 31 diverse bacterial species. [PDF]

open access: yesPLoS ONE, 2017
Genes that are indispensable for survival are essential genes. Many features have been proposed for computational prediction of essential genes. In this paper, the least absolute shrinkage and selection operator method was used to screen key sequence ...

Universal relations in the self-assembly of proteins and RNA [PDF]

open access: yes, 2014
Concepts rooted in physics are becoming increasingly important in biology as we transition to an era in which quantitative descriptions of all processes from molecular to cellular level are needed. In this essay I discuss two unexpected findings of universal behavior, uncommon in biology, in the self-assembly of proteins and RNA.

Single-trial Connectivity Estimation through the Least Absolute Shrinkage and Selection Operator

open access: yesAnnual International Conference of the IEEE Engineering in Medicine and Biology Society, 2019
Methods based on the use of multivariate autoregressive models (MVAR) have proved to be an accurate tool for the estimation of functional links between the activity originated in different brain regions.

Bayesian inversion of a diffusion model with application to biology

open access: yesJournal of Mathematical Biology, 2021
A common task in experimental sciences is to fit mathematical models to real-world measurements to improve understanding of natural phenomenon (reverse-engineering or inverse modelling).
