Robustness of Half‐Metallicity and Spin‐Dependent Transport in Defective Co2HfSn and Co2ZrSn Heusler Alloys

open access: yesAdvanced Electronic Materials, Volume 12, Issue 16, 24 August 2026.
Point defects strongly influence the spin‐dependent electronic and transport properties of Co2HfSn and Co2ZrSn Heusler alloys. First‐principles calculations reveal that Co vacancies preserve half‐metallicity, while anti‐site and swap defects introduce minority‐spin states that reduce spin selectivity.

Mandibular and Pharyngeal Muscles of Acanthias and Raia [PDF]

open access: yesThe American Naturalist, 1905
In the foregoing, all of the muscles of the head and the branchial region, with the exception of the eye muscles, have been considered. The two forms studied agree very closely when their difference in shape is considered. In the skate, as might be expected from its extreme modification, a few muscles are developed which are not found in the dogfish ...

Population Density and Spatial–Temporal Niche Use of Ship Rats and Italian Wall Lizards on a Small Adriatic Island

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
We quantified population density and spatial–temporal niche use of ship rats (Rattus rattus) and Italian wall lizards (Podarcis siculus) on a small uninhabited Adriatic islet using spatially explicit capture–recapture, distance sampling, and camera trapping.

Physical interpretation of Stephens' phenomenological parameters for anisotropic microstrain broadening in cubic systems

open access: yesJournal of Applied Crystallography, Volume 59, Issue 4, Page 1121-1128, August 2026.
This study emphasizes the physical interpretation of Stephens' phenomenological parameters with respect to the nature of dislocations in cubic symmetry, validated through illustrative examples based on modified Williamson–Hall plot analysis.Both the Stephens phenomenological model and the modified Williamson–Hall (mWH) plot analysis address the ...

Melanism in salamanders: effects of insularity, sex and size on dorsal colouration in Salamandra salamandra

open access: yesJournal of Zoology, Volume 329, Issue 4, Page 340-352, August 2026.
In this study we tested the effects of insularity on amphibian colouration using the fire salamander as a model system. Although increased melanism was not a consistent pattern across all islands, salamanders from one island exhibited higher proportions of black pigmentation than mainland populations, while insular populations overall showed reduced ...

Conventi dei Minori Osservanti della ex Provincia Lauretana: aggiornamento della bibliografia

open access: yesPicenum Seraphicum, 2019
Il contributo partendo dalla fondamentale opera Cronistoria dei frati Minori della Provincia Lauretana delle Marche di Antonio Talamonti intende aggiornare la bibliografia sui singoli conventi con gli studi pubblicati da quella data fino ad oggi.

Age‐related trends in niche position and specialization in Neotropical vertebrates

open access: yesEcography, Volume 2026, Issue 7, July 2026.
Species' niche positions and breadths within a region's environmental space, measured through ecological niche factor analysis (ENFA) as marginality and specialization, can reflect evolutionary constraints related to lineage age. The ‘internal incumbency' hypothesis predicts that older species, due to competitive preemption, occupy more central niche ...

The Pathogenicity Analysis of a Hypogonadotropic Hypogonadism Patient With the Novel Variant in the Deep Intronic Region of the PROK2 Gene

open access: yesMolecular Genetics &Genomic Medicine, Volume 14, Issue 7, July 2026.
We identified a deep intronic variant of PROK2 in one female patient with hypogonadotropic hypogonadism (HH) through whole‐genome sequencing (WGS). In vitro splicing assays and protein structure predictions indicated that this variant was likely pathogenic and might lead to this disease.
