Analysis of the Darcy-Brinkman flow with viscous dissipation and non-homogeneous thermal boundary condition

Mathematical Modelling and Analysis
This study investigates the steady-state Darcy-Brinkman flow within a thin, saturated porous domain, focusing on the effects of viscous dissipation and non-homogeneous boundary condition for the temperature.

PhyBaSE: A Bayesian structural equation model approach to causal inference in phylogenetic comparative analyses

Methods in Ecology and Evolution, Volume 16, Issue 6, Page 1136-1148, June 2025.
Abstract One of the main limitations of phylogenetic comparative analyses is that associations between traits can only be interpreted as correlations. Here, we present a novel Bayesian structural equation model (PhyBaSE) which allows us to disentangle direct from indirect relationships among variables to propose potential causal hypotheses while ...

A Strong Approximation in L2 for the Solutions of the Maxwell System With Highly Oscillating Periodic Coefficients

Mathematical Methods in the Applied Sciences, Volume 48, Issue 8, Page 9207-9224, 30 May 2025.
ABSTRACT We consider a Maxwell system on ℝ3$$ {\mathbb{R}}^3 $$ with highly oscillating periodic coefficients. It is known that the solutions converge in the weak‐ ∗$$ \ast $$ topology of L∞(0,T;L2(ℝ3))$$ {L}^{\infty}\left(0,T;\kern0.3em {L}^2\left({\mathbb{R}}^3\right)\right) $$ to the solution of a similar problem with constant coefficients given as ...

Sea F la función de felicidad ... Let F be the function of happiness ...

Cuadernos de Economía, 1994
Los economistas contemporáneos no estudian directamente, o pasan por alto, la felicidad del ser humano. Suponen que ésta depende del ingreso o de la utilidad de cada persona. En este artículo, la felicidad de un individuo genérico es considerada como una

Chemostat models with Monod and Haldane consumption functions and random environmental fluctuations

Mathematical Methods in the Applied Sciences, Volume 48, Issue 7, Page 7412-7431, 15 May 2025.
In this paper, we study the asymptotic dynamics of two chemostat models with random environmental fluctuations modeled by means of real noise, where different consumption functions for the consumer species (Monod and Haldane) are taking into account. For each model, our main goal is to investigate the existence of deterministic attracting sets.

Stochastic COVID‐19 epidemic model incorporating asymptomatic and isolated compartments

Mathematical Methods in the Applied Sciences, Volume 48, Issue 7, Page 8400-8422, 15 May 2025.
This study delves into the intricate dynamics of the COVID‐19 epidemic by extending a deterministic compartmental model incorporating asymptomatic, quarantined and isolated compartments, with a stochastic model capturing the natural randomness of the processes.
