Ground state solution of a noncooperative elliptic system
, 2013 In this paper, we study the existence of a ground state solution, that is, a non trivial solution with least energy, of a noncooperative semilinear elliptic system on a bounded domain.

Biological control via "ecological" damping: An approach that attenuates non-target effects [PDF]
, 2015 In this work we develop and analyze a mathematical model of biological control to prevent or attenuate the explosive increase of an invasive species population in a three-species food chain. We allow for finite time blow-up in the model as a mathematical

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Coastal hypoxia is profoundly affected by sediment depletion of oxygen and recycling of nutrients—processes sustained by long‐term accumulation of sediment organic matter. While sediment‐water interactions are widely recognized, quantitative understanding of sediment legacy effects remains limited. To address this gap, we developed a two‐layer

StochKit-FF: Efficient Systems Biology on Multicore Architectures [PDF]
, 2010 The stochastic modelling of biological systems is an informative, and in some cases, very adequate technique, which may however result in being more expensive than other modelling approaches, such as differential equations.

A Jacobian‐Free Newton‐Krylov Method for Cell‐Centred Finite Volume Solid Mechanics
International Journal for Numerical Methods in Engineering, Volume 127, Issue 3, 15 February 2026.ABSTRACT This study proposes a Jacobian‐free Newton‐Krylov approach for finite‐volume solid mechanics. Traditional Newton‐based approaches require explicit Jacobian matrix formation and storage, which can be computationally expensive and memory‐intensive.

An Agent-Based Model of Collective Emotions in Online Communities
, 2010 We develop a agent-based framework to model the emergence of collective emotions, which is applied to online communities. Agents individual emotions are described by their valence and arousal.

Two solutions for Dirichlet double phase problems with variable exponents
Advanced Nonlinear StudiesThis paper is devoted to the study of a double phase problem with variable exponents and Dirichlet boundary condition. Based on an abstract critical point theorem, we establish existence results under very general assumptions on the nonlinear term, such ...

Advanced Optical Materials, Volume 14, Issue 1, 9 January 2026.Continuous‐wave lasing from a small number of perovskite quantum dots is achieved by coupling their photoluminescence to open‐access curved dielectric cavities. This geometry confines their emission into a single optical mode, sharply narrowing linewidths in both spontaneous and lasing regimes.

Polymer ejection from strong spherical confinement
, 2015 We examine the ejection of an initially strongly confined flexible polymer from a spherical capsid through a nanoscale pore. We use molecular dynamics for unprecedentedly high initial monomer densities.

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.This study proposes a bi‐level optimization model to coordinate carbon reduction across multi‐echelon power equipment supply chains under carbon quota and trading policies. Results demonstrate that carbon price provides dual incentives for abatement and revenue generation, with the abatement cost coefficient being the dominant factor influencing ...
