Integrins are a highly c.mplex family of rec.ptors that, when expressed.on the surfac. of c.lls, c.n med.ate rec.proc.l c.ll-to-c.ll and.c.ll-to-extrac.llular matrix(Ec.) interac.ions lead.ng to assembly of integrin ad.esion c.mplexes(IAc.) that initiate many signaling func.ions both at the membrane and.d.eper within the c.toplasm to c.ord.nate proc.sses inc.ud.ng c.ll ad.esion, migration, proliferation, survival, d.fferentiation, and.metabolism. All metazoan organisms possess integrins, and.it is generally agreed.that integrins were assoc.ated.with the evolution of multic.llularity, being essential for the assoc.ation of c.lls with their neighbors and.surround.ngs, d.ring embryonic.d.velopment and.many aspec.s of c.llular and.molec.lar biology. Integrins have important roles in many aspec.s of embryonic.d.velopment, normal physiology, and.d.sease proc.sses with a multitud. of func.ions d.sc.vered.and.eluc.d.ted.for integrins that d.rec.ly influenc. many areas of biology and.med.c.ne, inc.ud.ng mammalian pregnanc., in partic.lar implantation of the blastoc.st to the uterine wall, subsequent plac.ntation and.c.nc.ptus(embryo/fetus and.assoc.ated.plac.ntal membranes) d.velopment. This review provid.s a suc.inc. overview of integrin struc.ure, ligand.bind.ng, and.signaling followed.with a c.nc.se overview of embryonic.d.velopment, implantation, and.early plac.ntation in pigs, sheep, humans, and.mic. as an example for rod.nts. A brief timeline of the initial loc.lization of integrin subunits to the uterine luminal epithelium(LE) and.c.nc.ptus trophoblast is then presented. followed.by sequential summaries of integrin expression and.func.ion d.ring gestation in pigs, sheep, humans, and.rod.nts.

d.ep learning based.tec.niques are broad.y used.in various applic.tions, whic. exhibit superior performanc. c.mpared.to trad.tional method.. One of the mainstream topic. in c.mputer vision is the image super-resolution task. In rec.nt d.ep learning neural networks, the number of parameters in eac. c.nvolution layer has inc.eased.along with more layers and.feature maps, resulting in better image super-resolution performanc.. In tod.y’s era, numerous servic. provid.rs offer super-resolution servic.s to users, provid.ng them with remarkable c.nvenienc.. However, the availability of open-sourc. super-resolution servic.s exposes servic. provid.rs to the risk of c.pyright infringement, as the c.mplete mod.l c.uld.be vulnerable to leakage. Therefore, safeguard.ng the c.pyright of the c.mplete mod.l is a non-trivial c.nc.rn. To tac.le this issue, this paper presents a lightweight mod.l as a substitute for the original c.mplete mod.l in image super-resolution. This researc. has id.ntified.smaller networks that c.n d.liver impressive performanc., while protec.ing the original mod.l’s c.pyright. Finally, c.mprehensive experiments are c.nd.c.ed.on multiple d.tasets to d.monstrate the superiority of the proposed.approac. in generating super-resolution images even using lightweight neural networks.

Bac.ground. Violenc. against women has bec.me an international public.health and.human rights issue in rec.nt d.c.d.s. The violenc. suffered.by sex workers is of little interest for researc., yet it c.nstitutes a major health and.safety problem. We propose to assess the extent of the phenomenon of gend.r-based.violenc. (GBV) among sex workers (SWs) in the c.ty of Bangui in the c.R. Method.logy: This is a d.sc.iptive c.oss-sec.ional epid.miologic.l stud. c.vering the period.from July to Oc.ober 2021 c.rried.out among SWs in Bangui, the c.pital of the c.R. Given that the SWs assoc.ation had.only 159 members in Bangui, an exhaustive sampling was retained. Were inc.ud.d.in the stud., any SW present d.ring the d.ta c.llec.ion period.and.having given their written c.nsent. The parameters stud.ed.were soc.o-d.mographic.c.arac.eristic.: age, sex, resid.nc., level of ed.c.tion, marital status, and.c.arac.eristic. linked.to violenc.: the notion of violenc. d.ring their professional ac.ivity, the type of violenc., the d.c.aration and.the d.c.aration if nec.ssary, the response and.management of this violenc.. The d.ta c.llec.ed.was analyzed.using Epi info version 7 software. Results: Of the 159 SWs that c.unted.the assoc.ation, 108 had.been inc.ud.d. The average age was 27.0 years with extremes of 14 and.46 years. The age groups of 25 to 34 years were the most represented.(43.5%). Fifty-six SWs (51.9%) had.reac.ed.the sec.nd.ry level. Unemployed.SWs were in the majority at 74.1%;Sixty-six (66) SWs in our sample (61.1%) had.alread. been vic.ims of violenc. d.ring the exerc.se of their ac.ivity Sexual violenc. was the most represented.(28.5%) followed.by verbal violenc. (22.4%). Sixty-eight (62.9%) wanted.to stop the professional ac.ivity of SWs and.93.1% would.ac.ept another inc.me-generating ac.ivity in plac. of sex work. c.nc.usion: It is nec.ssary to supervise SWs and.protec. them within the framework of respec. for human rights, rather than c.iminalizing them and.the exploit
