Tools for the analysis and visualisation of distributions and vector fields in surface forest fires modelling

Журнал Белорусского государственного университета: Математика, информатика, 2022
The problem of computer modelling of the spread of surface forest fires in a two-dimensional formulation is herein considered. We describe the initial-boundary value problem in the form of a system of partial differential equations in the accepted ...

A Bayesian Model for Estimation of Virus Reduction in Potable Reuse Treatment Trains and Quantitative Microbial Risk Assessment of Waterborne Viral Pathogens

Risk Analysis, Volume 46, Issue 9, September 2026.
ABSTRACT Understanding virus occurrence and reduction at advanced treatment facilities for potable water reuse constitutes a high‐priority research need to protect human health and to enhance available water supply alternatives. The objectives were to (1) determine log reduction values (LRVs) of 15 viruses by advanced wastewater treatment; (2) evaluate

Tuning Redox Dynamics in Cu‐Based Electrocatalysts: Effect of Secondary Metals

Advanced Functional Materials, Volume 36, Issue 68, 24 August 2026.
Advanced analysis of operando X‐ray absorption spectroscopy data reveals that secondary metals affect the redox processes in Cu‐based catalysts for electrocatalytic CO2 reduction. This influences the amount of oxides formed under pulsed reaction conditions and the distribution of reaction products.

Self‐Similar Blowup for the Cubic Schrödinger Equation

Communications on Pure and Applied Mathematics, Volume 79, Issue 8, Page 1831-1918, August 2026.
ABSTRACT We give a rigorous proof for the existence of a finite‐energy, self‐similar solution to the focusing cubic Schrödinger equation in three spatial dimensions. The proof is computer‐assisted and relies on a fixed point argument that shows the existence of a solution in the vicinity of a numerically constructed approximation.

By way of introduction: Modelling living systems, their diversity and their complexity: some methodological and theoretical problems☆☆Used and referenced software: Excel (Microsoft), Statview (SAS Institute), Mathematica (Wolfram Research) and Maple (Waterloo Maple Inc.), Grapher (application Mac OS.10.4, Apple Computer Inc.) and Dynamac (cf. 3).

Comptes Rendus. Biologies, 2005
Some principles for a current methodology for biological systems' modelling are presented. It seems possible to promote a model-centred approach of these complex systems. Among present questions, the role of mechanisms producing random or quasi-random issues is underlined, because they are implied in biological diversification and in resulting ...
