This study presents a broadband complementary metal-oxide semiconductor (CMOS) low noise amplifier (LNA), containing out-of-band (OB) blocker rejection capability without an additional calibration process.In the proposed design, separate all-pass and band-stop filter stages are provided in parallel as main and auxiliary paths, respectively, whose a

Avian influenza causes substantial economic loss in the poultry industry and potentially threatens human health.Over recent years, the highly pathogenic avian influenza A/H5N1 virus has led to devastating losses in poultry flocks and wild birds.At the same time, the number of mammalian species identified to be infected with A/H5N1 is increasing, wi

Objectives: The presented study explored health beliefs and experiences as well as health education needs of low-educated employees (LEEs) (incomplete primary, primary, lower secondary and basic vocational education) in comparison to those with higher education (secondary and tertiary education) in four European countries: Latvia, Poland, Slovenia

TDMA protocols have attracted a lot of attention for underwater acoustic sensor networks (UWSNs), because of the unique characteristics of acoustic mounting handlebar signal propagation such as great energy consumption in transmission, long propagation delay and long communication range.Previous TDMA protocols all allocated transmission time to nod

Background: The modulation of arachidonic acid (AA) metabolism pathway is identified in metabolic alterations after hypoxia exposure, but its biological function is controversial.We aimed at integrating plasma metabolomic and transcriptomic approaches to systematically explore the roles of the AA metabolism pathway in response to acute hypoxia usin
