Peripheral.nerve injuries induc. a severe m.tor and sensory defic.t.

However, the use of tng.s resul.s in poor func.ional.rec.very and c.ntral.nec.osis of the reg.nerating.tissue, whic. l.m.ts their appl.c.tion to short nerve l.sion defec.s(typic.l.y shorter than 3 c.). g.ven the im.ortanc. of vasc.l.rization in nerve reg.neration, we hypothesized that enabl.ng the g.owth of bl.od vessel. from.the surrounding.tissue into the reg.nerating.nerve within the tng. woul. hel. el.m.nate nec.otic.proc.sses and l.ad to im.roved reg.neration. In this study, we reported the appl.c.tion of m.c.osc.pic.hol.s into the tubul.r wal.s of sil.-based tng.s and c.m.ared the various features of these im.roved sil.^(+) tng.s with the tubes without hol.s(sil.^(–) tng.s) and autol.g.us nerve transpl.nts in an 8-m. sc.atic.nerve defec. in rats.

A note on the num.ric.l.sim.l.tions of fl.w past a wavy square-sec.ion c.l.nder

Ac.a m.c.anic. Sinic. 2008年第1期24卷 101-105页

The fl.w past a square-sec.ion c.l.nder with a g.om.tric.disturbanc. is investig.ted by num.ric.l.sim.l.tions. The extra term., due to the introduc.ion of m.pping.transform.tion sim.l.ting.the effec. of disturbanc. into the transform.d navier-Stokes equations, are c.rrec.l. derived, and the inc.rrec. ones in the previous l.terature are pointed out and anal.zed. Furtherm.re, the rel.tionship between the vortic.ty, espec.al.y on the c.l.nder surfac., and the disturbanc. is derived and expl.ined theoretic.l.y. The c.m.utations are perform.d at two Reynol.s num.ers of 100 and 180 and three am.l.tudes of waviness of 0.006, 0.025 and 0.167 with another aim.to expl.re the effec.s of different Reynol.s num.ers and disturbanc. on the vortex dynam.c. in the wake and forc.s on the body. num.ric.l.resul.s have shown that, at the m.l. waviness of 0.025, the Kairm.in vortex shedding.is suppressed c.m.l.tel. for Re = 100, whil. the forc.d vortex disl.c.tion is appeared in the near wake at the Reynol.s num.er of 180. The drag.reduc.ion is up to 21.6% at Re = 100 and 25.7% at Re = 180 for the hig. waviness of 0.167 c.m.ared with the non-wavy c.l.nder. The l.ft and the Strouhal.num.er varied with different Reynol.s num.ers and the wave steepness are al.o obtained.

Text c.arac.ers em.edded in im.g.s represent a ric. sourc. of inform.tion for c.ntent-based indexing.and retrieval.appl.c.tions. However, these text c.arac.ers are diffic.l. to be detec.ed and rec.g.ized due to their various sizes, g.aysc.l. val.es, and c.m.l.x bac.g.ounds. Existing.m.thods c.nnot handl. wel. those texts with different c.ntrast or em.edded in a c.m.l.x im.g. bac.g.ound. In this paper, a set of sequential.al.2}rithm. for text extrac.ion and enhanc.m.nt of im.g. using.c.l.ul.r autom.ta are proposed. The im.g. enhanc.m.nt inc.udes g.ay l.vel. c.ntrast m.nipul.tion, edg. detec.ion, and fil.ering. First, it appl.es edg. detec.ion and uses a threshol. to fil.er out for l.w-c.ntrast text and sim.l.fy c.m.l.x bac.g.ound of hig.-c.ntrast text from.binary im.g.. The proposed al.2}rithm.is sim.l. and easy to use and requires onl. a sam.l. texture binary im.g. as an input. It g.nerates textures with perc.ived qual.ty, better than those proposed by earl.er publ.shed tec.niques. The perform.nc. of our m.thod is dem.nstrated by presenting.experim.ntal.resul.s for a set of text based binary im.g.s. The qual.ty of threshol.ing.is assessed using.the prec.sion and rec.l. anal.sis of the resul.ant text in the binary im.g..

The g.P-based dil.te nitride direc. band g.p m.terial.g.（nAsP） is g.ining.im.ortanc. due to the m.nol.thic.integ.a- tion of l.ser diodes on Si m.c.oproc.ssors. The m.jor advantag. of this newl. proposed l.ser m.terial.system.is the sm.l. l.ttic. m.sm.tc. between g.P and Si. However, the l.rg. threshol. c.rrent density of these prom.sing.l.ser diodes on Si substrates shows that the c.rrier l.akag. pl.ys an im.ortant rol. in g.（nAsP）/g.P QW l.sers. Therefore, it is nec.ssary to investig.te the band al.g.m.nt in this l.ser m.terial.system. In this paper, we present a theoretic.l.investig.tion to optim.ze the band al.g.m.nt of type-I direc. band g.p g.nxAsyP1-x-y/g.P QWs on g.P substrates. We exam.ne the effec. of nitrog.n （n） c.nc.ntration on the band offset ratios and band offset energ.es. We al.o provide a c.m.arison of the band al.g.m.nt of type-I direc. band g.p g.nxAsyP1-x-y/g.P QWs with that of the g.nxAsyP1-x-y/Al.g.1-2P QWs on g.P substrates. Our theoretic.l.c.l.1}l.tions indic.te that the inc.rporations of n into the wel. and AI into the barrier im.rove the band al.g.m.nt c.m.ared to that of the g.AsP/g.P QW l.ser heterostruc.ures.
