Alpine ungulates adjust diel activity to the natural return of wolves amid anthropogenic pressures

Ecography, EarlyView.
As wolves recolonise their historical range across Europe, ungulates face predation once more – but in landscapes profoundly altered by human activity. This shift raises crucial questions about their capacity to express adaptive antipredator behaviours.

Alpha, beta and gamma diversity in relatively natural, mixed and transformed landscape scenarios

Ecography, EarlyView.
Biodiversity losses and biotic homogenisation associated with human‐induced land‐cover changes are key issues for ecology. However, the effects of human‐caused land‐use changes on biodiversity change at the landscape scale are not well understood. Combining the PREDICTS global biodiversity database with MODIS satellite‐based land cover from 2001 to ...

Enhanced Photocatalytic Reduction of CO2 to Complete CO Mediated by Donor–Acceptor Covalent Organic Frameworks

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A donor–acceptor (D–A) engineering strategy is applied to construct β‐ketoenamine‐linked COFs for CO2 photoreduction in pure water without sacrificial agents or photosensitizers. The designed TP‐TAPB COF, featuring the strongest D–A interaction, achieves a complete CO production rate of 464.6 μmol g−1. Strengthened intramolecular D–A interactions favor

To find the correlation between transverse cerebellar diameter measured by cranial ultrasound within 48 h of birth and gestational age as estimated by last menstrual period

Asian Journal of Medical Sciences
Background: Gestational age (GA) may be assessed at any time during pregnancy, and several modes of assessment exist, each requiring better diagnostic techniques that may result in more precise estimates of GA, which could lead to quicker medical ...

Rational Design of CdS QDs/CeO2 Nanocube S‐Scheme Heterojunctions for Highly Efficient C2H4 Scavenging in Fresh Produce Preservation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A novel S‐scheme heterojunction of CdS quantum dots on CeO2 nanocubes was designed to enhance charge separation and oxygen activation for efficient photocatalytic ethylene removal. The optimized composite achieved complete C2H4 degradation within 4 min under low‐intensity visible light, with a rate constant of 1.72 min−1. Mechanistic analysis confirmed

Mitigating VFA accumulation in hydrogen‐assisted anaerobic digestion through MEC integration

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Biological hydrogenotrophic methanization is a promising method to improve biogas quality in anaerobic digestion systems. However, hydrogen‐assisted anaerobic digesters (AD‐H2) are prone to volatile fatty acid (VFA) accumulation and process instability.

Pre‐operative transcranial Doppler ultrasound assessment of cerebral collateral circulation in children undergoing veno‐arterial extracorporeal membrane oxygenation or cardiac surgery

Journal of Medical Radiation Sciences, EarlyView.
A pre‐cannulation survey of the circle of Willis (CoW) using transcranial Doppler (TCD) ultrasound was implemented to assess cerebral collateral circulation in children undergoing VA ECMO or cardiac surgery with cervical cannulation. The technique, in use since 2019, employs high‐end ultrasound platforms to assess brain morphology, haemorrhage and ...
