A two-mass dynamic model of an electric vehicle is considered to obtain analytical dependences describing the gearshift process in a shaft-planetary gearbox. The calculations are based on optimal diagram shifting gears from low high without interruption power flow motor. At stage gear shifting, at which kinematic ratio gearbox changes u1 u2, Lagrange equations second kind used determine time an...
The SCL/TAL-1 gene encodes a basic helix-loop-helix transcription factor that is expressed in multipotent hematopoietic progenitors before lineage commitment. Its expression is maintained during differentiation along erythroid, mast, and megakaryocytic lineages, but is repressed after commitment to nonexpressing lineages. To begin to address the molecular mechanisms underlying this complex patt...
Recently, Brezis, Van Schaftingen and the second author [4] established a new formula for W ? 1 , p norm of function in C c ? ( R N ) . The was obtained by replacing L 2 Gagliardo semi-norm s with weak- quasi-norm setting = This provides characterization such norms, which complements celebrated Bourgain-Brezis-Mironescu (BBM) [1] In this paper, we obtain an analog case 0 particular, present any...
Central to reconstruction of cis-regulatory networks is identification and classification of naturally occurring transcription factor-binding sites according to the genes that they control. We have examined salient characteristics of 9-mers that occur in various orders and combinations in the proximal promoters of human genes. In evaluations of a dataset derived with respect to experimentally d...
In this work, the role of HDAC6, a type II histone deacetylase with tubulin deacetylase activity, in lymphocyte polarity, motility, and transmigration was explored. HDAC6 was localized at dynamic subcellular structures as leading lamellipodia and the uropod in migrating T-cells. However, HDAC6 activity did not appear to be involved in the polarity of migrating lymphocytes. Overexpression of HDA...
