Bi-Lipschitz Maps in Q-regular Loewner Spaces

引用

Acta Mathematica Sinica,English Series 2008年第9期24卷 1555-1568页

作者： Ke Ying CHEN Ai Nong FANG Department of Mathematics,Shanghai Jiaotong University,Shanghai 200240,p.R.China Department of Mathematics Shanghai Jiaotong University Shanghai 200240 P. R. China

By applying the theory of quasiconformal maps in measure metric spaces that was introduced by Heinonen-Koskela, we characterize bi-Lipschitz maps by modulus inequalities of rings and maximal, minimal derivatives in Q-regular Loewner spaces. Meanwhile the sufficient and necessary conditions for quasiconformal maps to become bi-Lipschitz maps are also obtained. These results generalize Rohde’s theorem in ? n and improve Balogh’s corresponding results in Carnot groups.

Cerebral pericytes are perivascular cells that stabilize blood vessels. Little is known about the plasticity of pericytes in the adult brain in vivo. Recently, using stateof-the-art technologies, including two-photon microscopy in combination with sophisticated Cre/loxp in vivo tracing techniques, a novel role of pericytes was revealed in vascular remodeling in the adult brain. Strikingly, after pericyte ablation, neighboring pericytes expand their processes and prevent vascular dilatation. This new knowledge provides insights into pericyte plasticity in the adult brain.

Orotidine Monophosphate Decarboxylase——A Fascinating Workhorse Enzyme with Therapeutic potential

引用

Journal of Genetics and Genomics 2015年第5期42卷 221-234页

Orotidine 5＇-monophosphate decarboxylase （ODCase） is known as one of the most proficient enzymes. The enzyme catalyzes the last reaction step of the de novo pyrimidine biosynthesis, the conversion from orotidine 5＇-monophosphate （OMp） to uridine 5＇-mono- phosphate. The enzyme is found in all three domains of life, Bacteria, Eukarya and Archaea. Multiple sequence alignment of 750 putative ODCase sequences resulted in five distinct groups. While the universally conserved DxKxxDx motif is present in all the groups, depending on the groups, several characteristic motifs and residues can be identified. Over 200 crystal structures of ODCases have been determined so far. The structures, together with biochemical assays and computational studies, elucidated that ODCase utilized both transition state stabilization and substrate distortion to accelerate the decarboxylation of its natural substrate. Stabilization of the vinyl anion intermediate by a conserved lysine residue at the catalytic site is considered the largest contributing factor to catalysis, while bending of the carboxyl group from the plane of the aromatic pyrimidine ring of OMp accounts for substrate distortion. A number of crystal structures of ODCases complexed with potential drug candidate molecules have also been determined, including with 6-iodo- uridine, a potential antimalarial agent.

Certain Algebraic Test for Analyzing Aperiodic Stability of Two-Dimensional Linear Discrete Systems

引用

Circuits and Systems 2016年第6期7卷 718-725页

作者： p. Ramesh Department of Electrical and Electronics Engineering Anna University University College of Engineering Ramanathapuram India

This paper addresses the new algebraic test to check the aperiodic stability of two dimensional linear time invariant discrete systems. Initially, the two dimensional characteristics equations are converted into equivalent one-dimensional equation. Further Fuller’s idea is applied on the equivalent one-dimensional characteristics equation. Then using the co-efficient of the characteristics equation, the routh table is formed to ascertain the aperiodic stability of the given two-dimensional linear discrete system. The illustrations were presented to show the applicability of the proposed technique.
