The SIR Model in a Moving Population: Propagation of Infection and Herd Immunity

Communications on Pure and Applied Mathematics, Volume 79, Issue 11, Page 2375-2429, November 2026.
ABSTRACT In a collection of particles performing independent random walks on Zd$\mathbb {Z}^d$ we study the spread of an infection with SIR dynamics. Susceptible particles become infected when they meet an infected particle. Infected particles heal and are removed at rate ν$\nu$.

Taxon‐Specific Loss in Scleractinian Living Coral Area Following a Bleaching Event Is Linked to Reef Structural Decline in the Central Red Sea

Ecology and Evolution, Volume 16, Issue 11, November 2026.
Coral bleaching is becoming more frequent and severe worldwide, yet its effects on reef structural complexity remain poorly understood compared with the well‐documented impacts on coral colonies and communities. We used a cross‐scale approach to link in situ thermal stress to coral colony‐scale bleaching and mortality and reef‐scale structural change ...

Correlation Properties of Heart Rate Variability for Exercise Intensity Monitoring and Prescription During Constant‐Load Cycling: A Comparison With Traditional Physiological Variables

European Journal of Sport Science, Volume 26, Issue 11, November 2026.
ABSTRACT This study investigated the applicability of the short‐term scaling exponent alpha 1 of detrended fluctuation analysis (DFA‐a1) as a marker of internal load during constant‐load cycling. The aim was to explore DFA‐a1 dynamics across the moderate, heavy, and severe intensity domains and assess its utility for both monitoring and prescribing ...

Promises and limitations of deep learning for predicting knee osteoarthritis progression from medical imaging: A systematic review

Knee Surgery, Sports Traumatology, Arthroscopy, Volume 34, Issue 11, Page 4219-4234, November 2026.
Abstract Purpose To systematically evaluate the performance, methodological quality, and translational barriers of deep learning (DL) models for predicting knee osteoarthritis (KOA) progression from medical imaging. Methods Following PRISMA guidelines, we searched PubMed, Scopus, and Web of Science (inception to June 2026) for peer‐reviewed studies ...

An Anisotropic Constitutive Model for Crushable Geomaterials Based on Non‐Stationary Critical State Line Concept

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 16, Page 5919-5935, November 2026.
ABSTRACT In this paper, the dependencies of granular soil behaviour on particle crushing and fabric anisotropy are formulated within a novel model based on bounding surface plasticity theory enriched by the non‐stationary critical state line (NCSL) concept.
