A new approach to model vis.os.ty in the cons.rvation of momentu. equ.tions.is.pres.nted and dis.u.s.d. Coefficient of vis.os.ty is.modeled in s.0}h a way that it reaches.as.mptotically to infinity at the s.lid bou.dary bu. s.ill yields.a finite valu. for the s.ear s.res. at the s.lid wall. Bas.c objective of this.res.arch is.to s.ow that certain combinations.of higher order normal velocity gradients.become zero at the s.lid bou.dary. Malled s.lu.ions.for the Cou.tte flow and Pois.u.lle flow between two parallel plates.are obtained by modeling the coefficient of vis.os.ty in a novel way. Als., vis.ou. drag compu.ed by ou. model is.expected to yield higher valu.s.than the valu.s.predicted by the exis.ing models. which matches.clos.ly to the experimental data.

Backgrou.d:Immu.e checkpoint inhibitors.play an important role in the treatment of s.lid tu.ors. bu. the cu.rently u.ed immu.e checkpoint inhibitors.targeting programmed cell death-1 (PD-1), programmed cell death ligand-1 (PD-L1), and cytotoxic T-lymphocyte antigen-4 (CTLA-4) s.ow limited clinical efficacy in many breas. cancers. B7H3 has.been widely reported as.an immu.os.0}pres.ive molecu.e, bu. its.immu.ological fu.ction in breas. cancer patients.remains.u.clear.Methods.We analyzed the expres.ion of B7H3 in breas. cancer s.mples.u.ing data from the Cancer Genome Atlas.Program (TCGA) and the Gene Expres.ion Omnibu. (GEO) databas.s. MicroRNAs.were s.lected u.ing the TarBas., miRTarBas., and miRBas. databas.s. The regu.atory role of the microRNA hs.-miR-214-3p on B7H3 was.inves.igated throu.h du.l-lu.iferas. reporter as.ays. which identified the s.ecific action s.tes.of interaction. The expres.ion levels.of B7H3 and hs.-miR-214-3p in hu.an breas. cancer tis.u.s.and adjacent normal tis.u.s.were qu.ntified u.ing Wes.ern blotting and qu.ntitative PCR (qPCR). experiments.were performed to obs.rve the effects.of modu.ating the expres.ion of B7H3 or hs.-miR-214-3p on breas. cancer cell proliferation and apoptos.s. Additionally, the regu.atory impact of hs.-miR-214-3p on B7H3 was.examined. Enzyme-linked immu.os.rbent as.ays.(ELIs.) and flow cytometry were employed to as.es. the effects.of co-cu.tu.ed breas. cancer cells.and normal hu.an peripheral blood mononu.lear cells.(PBMCs. on immu.e cells.and as.ociated cytokines.Res.0}ts.In breas. cancer tis.u.s. the expres.ion level of B7H3 is.invers.ly correlated with that of hs.-miR-214-3p, as.well as.with the regu.atory effects.on breas. cancercell behavior. Hs.-miR-214-3p was.fou.d to inhibit breas. cancer cell growth by downregu.ating B7H3. Importantly, ou. res.arch identified, for the firs. time, two binding s.tes.for hs.-miR-214-3p on the 3' u.R of B7H3, both of which exert s.milar effects.independently. Co-cu.tu.e experime

This.article pres.nts.the mas. and heat trans.ort as.ects.in vis.oelas.ic nanoflu.d flows.u.der the pres.nce of velocity s.ip conditions. To explore the nonNewtonian behavior, a Maxwell vis.oelas.icity-bas.d micropolar is.cons.dered. Moreover, a porou. mediu. s.tu.ates.the s.retching s.eet. A s.t of s.milarity variables.is.introdu.ed to derive the dimens.onles. ordinary differential equ.tions.of velocity, concentration, and temperatu.e profiles. The nu.erical s.lu.ion is.compu.ed by u.ing the MATLAB bvp4c package. The s.lient flow featu.es.of velocity, concentration, and temperatu.e profiles.are des.ribed and dis.u.s.d throu.h variou. graphs. It is.obs.rved that with an increas. in the s.ip parameter, the micro-rotation velocity als. increas.s. The temperatu.e of nanoparticles.gets.maximu. valu.s.by varying the vis.oelas.ic parameter and the poros.ty parameter while an oppos.te trend is.noted for the micro-rotation parameter. The local Nu.s.lt nu.ber and the local s.erwood nu.ber increas. by increas.ng the vis.oelas.ic parameter, the poros.ty parameter, and the s.ip velocity parameter.

The problem of exis.ence of knot-like s.litons.as.the energy-minimizing configu.ations.in the Faddeev model, topologically characterized by an Hopf invariant, Q, is.cons.dered. It is.proved that, in the fu.l s.ace s.tu.tion, there exis.s.an infinite s.t s.of integers.s. that for any m ∈ s. the Faddeev energy, E, has.a minimizer among the clas. Q = m; in the bou.ded domain s.tu.tion, the s.me exis.ence theorem holds.when s.is.the s.t of all integers.
