Abstract Background Tetrapods exhibit great diversity in limb structures among species and also between forelimbs and hindlimbs within species, diversity which frequently correlates with locomotor modes and life history.We aim to examine the potential relation of changes in developmental timing (heterochrony) to the origin of limb morphological div
Abstract Hepatitis B virus (HBV) infection remains a global health challenge.Despite the availability of effective preventive vaccines, millions of people are at risk of cirrhosis and hepatocellular carcinoma.Current drug therapies inhibit viral replication, slow the progression of liver fibrosis and reduce infectivity, but they rarely remove the c
The regenerative braking energy of heavy haul railway is abundant but poorly utilized, reflected by low regenerative energy quality and poor economic benefit.In order to reduce cost and save energy, a scheme of regenerative braking energy scheduling system for traction power supply of heavy haul railway is proposed.An energy dispatching device is i
Near-surface winds around the mountainous Caribbean islands contribute to orographic lifting and thermal diurnal rainfall that requires mesoscale analysis.Here, a new perspective is presented via high-resolution satellite and reanalysis products.Singular value decomposition is applied to 5 km cold-cloud duration satellite data to understand the lea
