Coexistence, crossover and extirpation in coalescent communities and ecotones

open access: yesOikos, Volume 2026, Issue 7, July 2026.
When two ecological communities come into contact, the strength of their mixing determines whether species coexist, extirpate, or extend their ranges. We present analytical formulas and simulations describing these transitions. Specifically, we derive abundance shifts upon community coalescence, identify the critical mixing strength leading to first ...

Dental Biofilm–Induced Gingivitis in Children and Adolescents Without Known Systemic Involvement: A Systematic Review

open access: yesJournal of Clinical Periodontology, Volume 53, Issue 7, Page 1226-1252, July 2026.
ABSTRACT Aim To synthesize evidence on gingival diseases and conditions in children and adolescents (< 18 years) without known systemic disorder involvement, focusing on their distribution, aetiology, diagnosis, management and oral health–related quality of life (OHRQoL).

Wall–chamber decompositions for generalised Monge–Ampère equations

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 1, July 2026.
Abstract Generalised Monge–Ampère (gMA) equations form a large class of PDE including Donaldson's J‐equation, inverse Hessian equations, some supercritical deformed Hermitian–Yang–Mills (dHYM) equations and some Z‐critical equations. Solvability of these equations is characterised by numerical criteria involving intersection numbers over all ...

Cerebral oxygenation and skeletal muscle responses to time trial, maximal oxygen uptake and time to exhaustion exercise

open access: yesExperimental Physiology, Volume 111, Issue 7, Page 3267-3279, 1 July 2026.
Abstract This study investigated cerebral and neuromuscular responses to three exercise models: time trial (TT), maximal oxygen uptake (V̇O2max${{\dot{V}}_{{{{\mathrm{O}}}_2}{\mathrm{max}}}}$) and time to exhaustion (TTE). Fourteen participants completed the tests in the following order: V̇O2max${{\dot{V}}_{{{{\mathrm{O}}}_2}{\mathrm{max}}}}$, TT and ...

Deterministic Neutron Transport and Multiphysics Experimental Safety Analyses at the High Flux Isotope Reactor

open access: yes, 2016
The computational ability to accurately predict the conditions in an experiment under irradiation is a valuable tool in the operation of a research reactor whose scientific mission includes isotope production, materials irradiation, and neutron ...

Reduced Mechanical Tactile Stimulation Under Space Microgravity Affects Synaptic Signaling and Contributes to Neuromuscular Aging in Caenorhabditis elegans

open access: yesThe FASEB Journal, Volume 40, Issue 12, 30 June 2026.
Microgravity (μG) reduces mechanical tactile stimulation in Caenorhabditis elegans, causing neuromuscular decline, altered gene expression, synaptic defects, and accelerated aging phenotypes. The gentle‐touch mechanoreceptor MEC‐4 mediates μG‐induced body length reduction and extracellular matrix gene downregulation.

Thermodynamics‐Based THMC Model for Solute Transport in Sorptive Fractured Rock: Coupling Multi‐Phase Flow, Heat, and Deformation

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Fractured porous rocks host a complex interplay of heat, fluids, deformation, and chemical reactions, yet their combined influence on solute transport remains poorly resolved. Here we show that these processes are more tightly coupled than previously assumed.

Thermo-hydro-mechanical modeling of 3D fractured rocks with coupled matrix-fracture hydraulics

open access: yes, 2006
International audienceWe present a preliminary study of fractured rock, including fracture network reconstruction and numerical flow simulations, as a first step towards a fully coupled Thermo-Hydro-Mechanical (T-H-M) analysis of a fractured granite ...
