Abstract Background Numerous megafauna species from northern latitudes went extinct during the Pleistocene/Holocene transition as a result of climate-induced habitat changes.However, several ungulate species managed to successfully track their habitats during this period to eventually Pod Vapes flourish and recolonise the holarctic regions.So far,

The stabilization problem for a class of discrete network control system with time-delay and packet loss in both S-C side and C-A side is researched in this paper.Firstly, two independent Nail Treatments discrete Markov chains are used to describe the network time-delay from sensor to controller and the network time-delay from controller to actuato

This paper focuses on the nonlinear dynamics modeling and parameter identification of an Aluminum Honeycomb Panel (AHP) with multiple bolted joints.Finite element method using eight-node solid elements is exploited to model the panel and the bolted connection interface as a homogeneous, isotropic plate and as a thin layer of nonlinear elastic-plast

A single-phase axially-magnetized permanent-magnet (PM) oscillating machine which can be integrated with a free-piston Stirling engine to generate electric power, is investigated for miniature aerospace power sources.Machine structure, operating principle and detent force characteristic are elaborately studied.With the sinusoidal speed characterist

ABSTRACT: This study was conducted to investigate the effects of dietary Accessories purple sweet potato polysaccharide (PSPP) supplementation on production performance, egg quality characteristics, jejunal morphology, and gut microbiota modulation of Hy-line Brown laying hens.A total of 288 23-wk-old Hy-line Brown laying hens were randomly divided
