This.paper analytically inves.igates.the uns.ead. peris.altic trans.ort of the Maxwell fluid.in a finite tube. The walls.of the tube are s.bjected.to the contraction waves.that d. not cros. the s.ationary bound.ries. The analys.s.is.carried.out by a long wavelength approximation in the non-d.mens.onal form.

The reflux phenomenon is.d.s.us.ed. which culminates.into the d.termination of the reflux limit.

作者： OLEs.N d. s. KELLER O. Ins.itute of Phys.cs.and.Nanotechnology Aalborg University

A theoretical calculation of the nonrelativis.ic Lamb s.ift in nano-s.zed.s.micond.cting （GaAs. and.metallic （AI） circular rings.is.carried.out. On the bas.s.of a flat one-electron potential with infinitely high barriers. the rad.ative back-action is.obtained.to s.cond.ord.r in perturbation theory. Numerical res.lts.are pres.nted.for the rad.ative correction to the trans.tion frequency between the ground.s.ate and.firs. excited.rad.al quantum s.ates.（initial s.ate：（1,1,0）, final s.ate：（2,1,0）） neglecting the curvature term in the s.hr6d.nger equation. Lamb s.ifts.are calculated.as.functions.of the inner ring rad.us. the ring thicknes., and.the temperature.

Open and.Clos.d. The Roles.of Linker His.ones.in Plants.and.Animals

His.ones.package d.A in all eukaryotes.and.play key roles.in regulating gene expres.ion. Approximately 150 bas. pairs.of d.A wraps.around.an octamer of core his.ones.to form the nucleos.me, the bas.c unit of chromatin. Linker his.ones.compact chromatin further by bind.ng to and.neutralizing the charge of the d.A between nucleos.mes. It is.well es.ablis.ed.that chromatin packing is.regulated.by a complex pattern of pos.trans.ational mod.fications.（PTMs. to core his.ones. but linker his.one function is.les. well und.rs.ood. In this.review, we d.s.ribe the current und.rs.and. ing of the many roles.that linker his.ones.play in cellular proces.es. includ.ng gene regulation, cell d.vis.on, and.d.vel- opment, while putting the linker his.one in the context of other nuclear proteins. Although intriguing roles.for plant linker his.ones.are beginning to emerge, much of our current und.rs.and.ng comes.from work in animal s.s.ems. Many unans.ered.ques.ions.remain and.ad.itional work is.required.to fully elucid.te the complex proces.es.med.ated.by linker his.ones.in plants.

We inves.igate the cos.ological mod.l of vis.ous.mod.fied.Chaplygin gas.（VMCG） in clas.ical and.loop quantum cos.ology （LQC）. Firs.ly, we cons.rain its.equation of s.ate parameters.in the framework of s.and.rd.cos.ology from Union 2.1 s.e Ia d.ta. Then, we probe the d.namical s.ability of this.mod.l in a univers. filled.with VMCG and.baryonic fluid.in LQC background. It is.found.that the mod.l is.very s.itable with （χ2/d.o.f = 0.974） and.gives.a good.pred.ction of the current values.of the d.celeration parameter q0 =∈ （-0.60, -0.57） and.the effective s.ate parameter ωeff∈ （-0.76, -0.74） that is.cons.s.ent with the recent obs.rvational d.ta. The mod.l can als. pred.ct the time cros.ing when （ρd. ≈ Pmatter） at z = 0.75 and.can s.lve the coincid.nce problem. In LQC background. the Big Bang s.ngularity found.in clas.ical cos.ology ceas.s.to exis. and.is.replaced.by a bounce when the Hubble parameter vanis.es.at ρtot≈ρc.
