People and Nature, EarlyView.Abstract Local religious traditions serve as informal environmental institutions, characterized by socially embedded norms that guide behaviour without formal enforcement and influence human–environment interactions. This study investigates the role of Bonbibi worship as a system of moral regulation in the Bangladeshi Sundarbans and examines the ...

Wildlife Biology, EarlyView.Exploration of new wildlife surveying methodologies that leverage advances in sensor technology and machine learning has led to tentative research into the application of seismology techniques. This, most commonly, involves the deployment of a footfall trap – a seismic sensor and data logger customised for wildlife footfall.

Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection
Advanced Materials, Volume 38, Issue 36, 26 June 2026.Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...

Improved CPD based DOA estimation of nested array
Dianxin kexue, 2021 In order to avoid searching the peak value in space domain, when estimating nested array’s the direction of direction of arrival(DOA), the canonical polyadic decomposition(CPD) was applied into the nested array, namely using the one time singular value ...

Hong Kong Journal of Emergency Medicine, Volume 33, Issue 3, June 2026.Abstract Background Out‐of‐hospital cardiac arrests (OHCAs) are an important global health burden, and risk factors for patients with dispatcher‐unrecognized OHCAs have not yet been well investigated. Objectives The purpose of this study was to evaluate the association between multiple‐ambulance dispatches and clinical outcomes in patients with ...
