Research on Nonuniform Ageing State Assessment of Oil‐Immersed Power Transformers Based on PCA–GWO–RF Algorithm

High Voltage, EarlyView.
ABSTRACT The condition assessment of oil–paper insulation is critical for oil–immersed power transformers, which are fundamental to the reliability of modern power systems. The primary limitation of traditional transformer ageing assessment lies in its macroscopic, whole‐unit approach, which fails to account for the localised effects of nonuniform ...

Divergence Linked to Possible Ecological Speciation in Blind Mole Rats: Integration of Thermal Biology and Bite Force in the Upper Galilee Blind Mole Rat (Nannospalax galili)

Integrative Zoology, EarlyView.
Basalt‐dwelling blind mole rats maintain lower body temperatures, show greater post‐digging thermal increases, and dig more efficiently than those from rendzina soils. Although metabolic rates and bite force did not differ between populations, these thermal and physiological shifts align with the greater mechanical resistance and seasonal hypoxia of ...

Diagnostic Guidelines for the Evaluation of Choledocholithiasis in Patients With Acute Biliary Presentations: A Study of Their Applicability and Feasibility in a Publicly Funded Healthcare System

ANZ Journal of Surgery, EarlyView.
ABSTRACT Background The American and European Societies of Gastrointestinal Endoscopy (ASGE and ESGE) have published diagnostic guidelines for the evaluation of choledocholithiasis. The applicability and feasibility of these guidelines in a publicly funded health care system, such as ours in Aotearoa New Zealand, are not known. This retrospective study

Tongue and Glottis Morphology of Cathartes aura and the Secret of Its Functional Adaptation

Acta Zoologica, EarlyView.
ABSTRACT Cathartes aura, commonly known as the Turkey vulture, is a scavenger bird belonging to the family Cathartidae that is widely distributed throughout the Americas and classified as a New World vulture. Its diet primarily consists of small‐sized carcasses, predominantly of wild animals.
