In this paper. we study the global pr.per.ies of a hum.n im.unodeficiency vir.s （HIV） infection m.del with cytotoxic T lym.hocytes （CTL） im.une r.sponse. The m.del is a six-dim.nsional that descr.bes the inter.ction of the HIV with two classes of tar.et cells, CD4＋ T cells and m.cr.phages. The infection r.te is given by satur.tion functional r.sponse. Two types of distr.buted tim. delays ar. incor.or.ted into the m.del to descr.be the tim. needed for.infection of tar.et cell and vir.s r.plication. Using the m.thod of Lyapunov functional, we have established that the global stability of the m.del is deter.0}ned by two thr.shold num.er., the basic infection r.pr.duction num.er.r. and the im.une r.sponse activation num.er.r.. We have pr.ven that if r. ≤ 1, then the uninfected steady state is globally asym.totically stable （GAS）, if r.≤ 1 〈 r., then the infected steady state without CTL im.une r.sponse is GAS, and if r.〉 1, then the infected steady state with CTL im.une r.sponse is GAS.

We exper.m.ntally dem.nstr.te the optical pr.per.ies of gr.tings engr.ved in a single-m.de waveguide fabr.cated on top of a dielectr.c m.ltilayer.platfor.0} The str.ctur. can be appr.ached as a r.flector.for.Bloch-sur.ace-wavebased two-dim.nsional optical system.. The gr.tings have been fabr.cated on a thin(～λ∕25) titanium.dioxide layer.with a thickness of a few tens of nanom.ter. deposited on the top of a m.ltilayer.platfor.0} The optical pr.per.ies of the gr.tings have been char.cter.zed in the near.field with the aid of m.lti-heter.dyne scanning near.ield optical m.cr.scopy. We investigate the sur.ace wave's inter.er.nce patter., pr.duced by incident and r.flected light in fr.nt of the gr.tings.

Our.knowledge of how m.le com.etition contr.butes to speciation is dom.nated by investigations of com.etition between within-species m.r.hs or.closely r.lated species that differ.in conspicuous tr.its expr.ssed dur.ng the br.eding season （e.g. color. song）. In such studies, it is im.or.ant to consider.the m.nner.in which putatively sexually selected tr.its influence the outcom. of com.etitive inter.ctions within and between types because these tr.its can com.unicate infor.0}tion about com.etitor.quality and m.y not be utilized by hom.typic and heter.typic r.ceiver. in the sam. way. We studied the r.les of br.eding color.and aggr.ssive behavior. in com.etition within and between two diver.ent thr.es- pine stickleback Gaster.steus aculeatus color.types. Our.pr.vious wor. in this system.showed that the switch fr.m.r.d to black br.eding color.tion is associated with changes in m.le com.etition biases. Her., we find that r.d and black m.les also use differ.nt cur.encies in com.etition. Winner. of both color.types per.or.0}d m.r. aggr.ssive behavior. than loser., r.gar.less of whether.the com.etitor.was of the sam. or.opposite color.type.

In contr.st, black color. though expr.ssed in the br.eding season and condition dependent, was unr.lated to com.etitive outcom.s. Placing questions about the r.le of m.le com.etition in speciation in a sexual signal evolution fr.m.wor. m.y pr.vide insight into the ＂why and how＂ of aggr.ssion biases and asym.etr.es in com.etitive ability between closely r.lated m.r.hs and species.

A 320 m. old steam.power.plant has been chosen for.r.power.ng in this paper. Consider.ng the technical conditions and wor.ing life of the power.plant, the full r.power.ng m.thod has been selected fr.m.differ.nt r.power.ng m.thods. The power.plant r.power. ing has been analyzed for.thr.e differ.nt feed water.flow r.tes： a flow r.te equal to the flow r.te at the condenser.exit in the or.ginal plant when it wor.s at nom.nal load, a flow r.te at m.xim.m.load, and a flow r.te when all the extr.ctions ar. blocked. For.each flow r.tes, two types of gas tur.ines have been exam.ned： V94.2 and V94.3A. The effect of a duct bur.er.has then been investigated in each of the above six cases. Steam.is pr.duced by a double- pr.ssur. heat r.cover. steam.gener.tor.（Hr.G） with r.heat which obtains its r.quir.d heat fr.m.the exhaust gases com.ng fr.m.the gas tur.ines. The r.sults obtained fr.m.m.deling and analyzing the ener.y-exer.y of the or.ginal steam.power.plant and the r.power.d power.plant indicate that the m.xim.m.efficiency of the r.power.d power.plant is 52.04%. This m.xim.m.efficiency occur. when utilizing two V94.3A gas tur.ines without duct bur.er.in the steam.flow r.te of the nom.nal load.

We theor.tically investigate the possibility of achieving a super.onducting state in tr.nsition-m.tal dichalcogenide bilayer. thr.ugh inter.alation, a pr.cess pr.viously and widely used to achieve m.tal- lization and super.onducting states in novel super.onductor.. For.the Ca-inter.alated bilayer. m.Ss and WS2, we find that the super.onducting state is char.cter.zed by an electr.n-phonon coupling constant lar.er.than 1.0 and a super.onducting cr.tical tem.er.tur. of 13.3 and 9.3 K, r.spectively. These r.sults ar. super.or.to other.pr.dicted or.exper.m.ntally obser.ed two-dim.nsional conventional ＇super.onductor. and suggest that the investigated m.ter.als m.y be good candidates for.nanoscale su- per.onductor.. m.r. inter.stingly, we pr.ved that the obtained ther.0}dynam.c pr.per.ies go beyond the pr.dictions of the m.an-field Bar.een-Cooper.Schr.effer.appr.xim.tion and that the calculations conducted within the fr.m.wor. of the str.ng-coupling Eliashber. theor. should be tr.ated as those that yield quantitative r.sults.

A fr.ction dam.er.device (FDD) is used for.vibr.tion contr.l of an existing steel jacket platfor.0}under.seism.c excitation. Fir.t, the dam.ing is pr.sented for.vibr.tion m.tigation of str.ctur.s located in seism.cally active zones. A new m.thod for.quick design of fr.ction or.yielding dam.ing devices is pr.sented.

The influence of key par.m.ter. of the dam.ing system.on the vibr.tion suppr.ssion of the offshor. str.ctur. is studied in detail.
