Abstract We propose a Mellin space approach to the evaluation of late-time momentum-space correlation functions of quantum fields in (d + 1)-dimensional de Sitter Shirt space.The Mellin-Barnes representation makes manifest the analytic structure of late-time correlators and, more generally, provides a convenient general d framework for the study of

Silica glass, known for its brittleness, weight, and non-biodegradable nature, faces challenges in finding suitable alternatives.Transparent wood, made by infusing polymers into wood, shows promise but is hindered by limited availability of wood in China and fire risks associated with its use.This study explores the potential of utilizing bamboo, w

In order to gain an improvement of safety or turbo air m3f72-3-n availability measures of the safety-relevant control system through employment of redundancy a redundant system has to comply with the requirement on independence of redundant parts.If the requirements on the independence of redundant parts are unfulfilled, then a common-cause failure

Large numbers of harbor seals (Phoca vitulina) use habitat in tidewater glaciers in Alaska for pupping, breeding, and molting.Glacial fjords are also popular tourist destinations; however, visitation by numerous vessels can result in disturbance of seals during critical life-history phases.We explored factors affecting haul-out behavior of harbor s
