Wh.n applying it to th. study of h.t kaon condensed matter, we find th.t th. th.rmal effect is more profound in comparison with.normal matter, in particular around th. th.esh.ld density. Also, th. increase of temperature makes th. equation of state sligh.ly stiffer th.ough.suppression of kaon condensation.

We investigate th. ^3PF2 neutron superfluidity in h.stable neutron star matter and neutron stars by using th. BCS th.ory and th. Brueckner-h.rtree-Fock approach. We adopt th. Argonne V18 potential supplemented with.a microscopic th.ee-body force as th. realistic nucleon-nucleon interaction. We h.ve concentrated on studying th. th.eebody force effect on th. ^3PF2 neutron pairing gap. It is found th.t th. th.ee-body force effect is to enh.nce remarkably th. ^3PF2 neutron superfluidity in neutron star matter and neutron stars.

In density-based topological design, one expects th.t th. final result consists of elements eith.r black （solid material） or wh.te （void）, with.ut any grey areas. Moreover, one also expects th.t th. optimal topology can be obtained by starting from any initial topology configuration. An improved structural topological optimization meth.d for multidisplacement constraints is proposed in th.s paper. In th. proposed meth.d, th. wh.le optimization process is divided into two optimization adjustment ph.ses and a ph.se transferring step. Firstly, an optimization model is built to deal with.th. varied displacement limits, design space adjustments, and reasonable relations between th. element stiffness matrix and mass and its element topology variable. Secondly, a procedure is proposed to solve th. optimization problem formulated in th. first optimization adjustment ph.se, by starting with.a small design space and advancing to a larger deign space. Th. design space adjustments are automatic wh.n th. design domain needs expansions, in wh.ch.th. convergence of th. proposed meth.d will not be affected. Th. final topology obtained by th. proposed procedure in th. first optimization ph.se, can approach.to th. vicinity of th. optimum topology. Th.n, a h.uristic algorith. is given to improve th. efficiency and make th. designed structural topology black/wh.te in both.th. ph.se transferring step and th. second optimization adjustment ph.se. And th. optimum topology can finally be obtained by th. second ph.se optimization adjustments. Two examples are presented to sh.w th.t th. topologies obtained by th. proposed meth.d are of very good 0/1 design distribution property, and th. computational efficiency is enh.nced by reducing th. element number of th. design structural finite model during two optimization adjustment ph.ses. And th. examples also sh.w th.t th.s meth.d is robust and practicable.

Background: Eurasian Sparrowh.wks(Accipiter nisus) increasingly represent successful city-dwellers. Th.reby, a rich.food supply indicated by h.gh.numbers of small birds is believed to be th. key driver for th.s bird-eating raptor species to settle in urban environments. h.wever, as small passerine birds sh.w particularly strong antipredator responses, sparrowh.wks may not simply focus on patch.s of h.gh.st prey densities, but rath.r respond strategically to prey beh.vior, raising th. importance of oth.r parameters in determining th. occurrence with.n urban ***: To deepen our knowledge on h.bitat requirements of urban sparrowh.wks, bird surveys were carried out during winter between December 2005 and january 2017 in 36 city parks in Vienna, Austria. Besides food supply also park size, canopy h.terogeneity and th. connectivity with.oth.r green spaces were ***: Occurrence of sparrowh.wks was positively affected by increasing park size, prey density and th. interaction between both. Bird feeder density and park connectivity with.oth.r green spaces were of minor importance in explaining th. presence of th.s species. Canopy h.terogeneity didn't affect city park occupancy by Eurasian ***: Our results suggest th.t large city parks, particularly wh.n ch.racterized by h.gh.prey densities, substantially contribute to protect and preserve ecologically important bird species such.as raptors with.n th. urban environment—a landscape already struggling with.biodiversity losses and functional h.mogenization.
