摘要:... Results We introduce Plastid Genome Annotator (PGA), a standalone command line tool that can perform rapid, accurate, and flexible batch annotation of newly generated target plastomes based on well-annotated reference plastomes. In contrast to current existing tools, PGA uses...

摘要:Prostaglandin analogs (PGAs) are commonly used to treat glaucoma because of their powerful intraocular pressure lowering effect. However, various periorbital changes associated with the use of PGAs have been reported. We investigated the incidence of periorbital changes in Korean...

摘要:... anthracis are the plasmid encoded tripartite toxins (pXO1) and poly-γ-glutamic acid (PGA) capsule (pXO2). B. endophyticus isolated alongside B. anthracis from animals that died of anthrax in Northern Cape Province (NCP), South Africa, harbored polyglutamate genes. The stud...

摘要:Abstract Background Penicillin G acylase of Escherichia coli (PGAEc) is a commercially valuable enzyme for which efficient bacterial expression systems have been developed. The enzyme is used as a catalyst for the hydrolytic production of β-lactam nuclei or for th...

摘要:In this paper a new approach for controlling the gain of a programmable gain amplifier (PGA) using an eight-bit digital word has been proposed. Eight stages of R–2R ladder attenuators have been employed for attenuating the input signal. The output of the ladder network feeds ...

摘要:Abstract(#br)This paper analyzes high linearity Cherry–Hopper programmable-gain-amplifier (PGA), which is a cascade of linear transconductance (Gm) stage and transimpedance (TIA) stage. Basing on these analysis, reasons for gain peaking of Gm–TIA PGA are discussed. A Gm...

摘要:... The maximum horizontal PGA of 0.89 g is observed at station Garsain. The mean PGA value exceeded 0.8 g at five stations. The estimated acceleration time histories can be used to estimate the safety of the existing structures and design values for the construction of impo...
