The centralized power supply and distribution system of power conditioning unit (PCU) based on the architecture of sequential switching shunt regulator (S3R), sequential switching shunt series regulator (S4R), or their diversion has been widely used in spacecraft.
This is achieved by the sequential location of these regulator genes on the chromosome and through the use of DNA methylation to control gene expression; for example, the dnaA promoter is expressed only when DNA is fully methylated while hemimethylation promotes transcription of ctrA [17].
Regulator-regulated gene associations.
Likewise, sequential APC-dependent proteolysis of mitotic regulators is likely to make important contributions to ordered mitotic progression [ 13].
Dominant follicle selection, growth, and maturation, as well as ovulation, oocyte quality, and subsequent corpus luteum function, depend on sequential actions of gonadotropins and intraovarian regulators, including the insulin-like growth factor (IGF) system (Fortune 1994; Kwintkiewicz and Giudice 2009).
Sequential turnover of certain cell cycle regulators, including cyclins and CKIs p21cip1/waf1 and p27kip1, are mediated by the 20S proteasome, which promotes proteolytic degradation through the ubiquitin/proteasome pathway.
The regulation of these processes involves sequential events including the binding of TFs to cis-regulatory elements (CREs) and the recruitment of chromatin regulators, resulting in changes of chromatin structure and activation or repression of cell-type-specific genes15.
The first and most important stage of the space-walk involved the replacement of a defective "sequential shunt unit", one of the eight voltage regulators controlling electrical power from the space station's eight solar arrays.
Recent data from murine wound models have identified monocytes/macrophages as critical regulators of distinct functions during the sequential stages of wound healing.
To do this, the following sequential studies are carried out: (1) Two control algorithms, linear quadratic regulator (LQR) and acceleration feedback control algorithm, are analyzed and used as the control algorithms.
