Space‐Time FEM Solution of Dynamic Contact Problem With Discontinuous Velocity for Multiple Impact of Deformed Bar Using PDAS Method

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 7, Page 5897-5912, 15 May 2026.
ABSTRACT A class of one‐dimensional impact and dynamic contact problems taking into account non‐smooth velocities is studied. The new space‐time finite element approximation of dynamic variational inequalities is suggested. The non‐smooth solution for the impact of an obstacle by an elastic bar and its energy conservation under persistency conditions ...

Intercolony and Intra‐Annual Variations in Isotopic Niche of Red‐Footed Boobies Sula sula in the Tropical Indian Ocean

open access: yesEcological Research, Volume 41, Issue 3, May 2026.
We compared the diet and assessed geographic and seasonal variations in the isotopic niches of red‐footed boobies across three Indian Ocean atolls. Our results demonstrate plasticity in both diet and trophic niche, likely driven by local environmental conditions, breeding stages, and colony‐specific factors.

Influence of Sex and Diagnosis on Clinical Variables and Neurocognitive Performance in Severe Mental Illness. Results From the PsyCourse Study

open access: yesActa Psychiatrica Scandinavica, Volume 153, Issue 5, Page 449-467, May 2026.
ABSTRACT Introduction Bipolar disorder (BD) and schizophrenia (SZ) are serious mental illnesses (SMI) with overlapping symptoms but distinct differences in onset and course. Sex differences are an area of growing interest in SMI. This study aims to examine potential interactions between sex and diagnosis across a broad range of variables, to compare ...

Congenital aniridia: European COST action ANIRIDIA‐NET guidelines for diagnosis, management and care

open access: yesActa Ophthalmologica, Volume 104, Issue 3, Page 267-279, May 2026.
Abstract Congenital aniridia is a rare ocular disorder affecting the majority of eye structures and can be associated with systemic manifestations. The main visible phenotypic characteristic is the partial or complete absence of the iris; however, foveal hypoplasia is a more frequent and reliable clinical sign. Other ocular comorbidities are associated
