Asymptotic behavior of a system of micropolar equations

Electronic Journal of Qualitative Theory of Differential Equations, 2016
This work is concerned with three-dimensional micropolar fluids flows in a bounded domain with boundary of class $C^{\infty}.$ Based on the theory of dissipative systems, we prove the existence of a restricted global attractors for local semiflows on ...

Do Ambitious Goals Call for Stringent Policy? The Stringency, Target Sectors, and Measures of Finland's Climate and Energy Policy in Response to EU Greenhouse Gas Emission Targets

Review of Policy Research, Volume 43, Issue 1, January 2026.
ABSTRACT This article examines how the climate and energy policy in Finland changed between the two parliamentary terms of 2015–2019 and 2019–2023, when the EU tightened its greenhouse gas emission targets. We analyze the relevant policy measures (N = 223) of five government strategic plans and evaluate their stringency, i.e., their compulsory and ...

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 ...

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.

Impact of deep or ovarian endometriosis on pelvic pain and quality of life: prospective cross‐sectional ultrasound study

Ultrasound in Obstetrics &Gynecology, Volume 65, Issue 3, Page 372-383, March 2025.
ABSTRACT Objective To assess whether premenopausal women diagnosed with deep or ovarian endometriosis on transvaginal sonography (TVS) were more likely to suffer from dyspareunia and pelvic pain symptoms, and have a lower quality of life, compared to women without sonographically diagnosed deep or ovarian endometriosis.
