Integrating technical and scientific approaches to restore rupicolous plants threatened by climbing activities

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Rocky habitats are fragile ecosystems that host unique biodiversity and are increasingly threatened by the rapid expansion of outdoor climbing. In the northwestern region of El Bierzo (Spain), populations of the endemic rupicolous species Petrocoptis grandiflora and P. pyrenaica ssp. viscosa have experienced severe declines linked

Osteology and arthrology of the ankle and tarsometatarsus of anoles (Iguania: Anolidae): not convergent with geckos but divergent from the ancestral iguanian condition

open access: yesJournal of Anatomy, Volume 248, Issue 6, Page 1002-1025, June 2026.
Geckos and anoline iguanid lizards are well‐known for their possession of adhesive toepads, which are generally regarded as being convergent structures. We show that the anatomical configuration of the foot in these two lineages differs markedly and that these differences likely relate to the contrasing ways they deploy their adhesive systems and ...

Silicosis, Sarcoidosis, and Silicosarcoidosis Are Overlapping Diagnoses and Difficult to Differentiate

open access: yesAmerican Journal of Industrial Medicine, Volume 69, Issue 5, Page 313-322, May 2026.
ABSTRACT We evaluated 12 workers with documented exposure to respirable crystalline silica who were referred to a tertiary care center due to clinical suspicion of silicosis, sarcoidosis, or silicosarcoidosis. Although silica exposure is a well‐established risk factor for silicosis and has been associated with autoimmune diseases, mycobacterial ...

Phase diagram and isotope effect in (PrEu)_0.7Ca_0.3CoO_3 cobaltites exhibiting spin-state transitions

open access: yes, 2010
We present the study of magnetization, thermal expansion, specific heat, resistivity, and a.c. susceptibility of (Pr$_{1-y}$Eu$_y$)$_{0.7}$Ca$_{0.3}$CoO$_3$ cobaltites. The measurements were performed on ceramic samples with $y = 0.12 - 0.26$ and $y = 1$.

Managing maternity: Moving care, not patients, using artificial intelligence (AI), internet‐of‐things (IOT) and point‐of‐care testing (POCT) devices

open access: yesInternational Journal of Gynecology &Obstetrics, Volume 173, Issue 2, Page 602-613, May 2026.
Abstract The integration of artificial intelligence (AI) into healthcare is accelerating and maternity care is at a pivotal moment for the strategic implementation of these technologies. This article explores how AI‐assisted women's health innovations, often termed “FemTech,” may transform pregnancy care by addressing long‐standing disparities ...

Experimental Characterization of PCI Sensitivity for Industrial Ultrasonic Testing Applications

open access: yese-Journal of Nondestructive Testing
Phase Coherence Imaging (PCI) is a recent evolution of the Total Focusing Method (TFM) in ultrasonic Non-Destructive Testing (NDT). Unlike TFM, PCI relies exclusively on phase information and produces normalized coherence factors instead of amplitude ...
