The equilibrium structures and.electronic structure of LaNi5-xg.x （x=0, 0.5, 1.0） compound. have been investig.ted.by all-electron calculations. Based.on the full g.ometry optimization, the d.nsities of states and.electron d.nsities of LaNi5-xg.x are plotted.and.analyzed. It is clear that the substitution of g. at the Ni site lead. to a prog.essive filling.of the Ni-d.band., the ionic interaction between Ni and.Ni, with g. plays a d.minant role in the stability of LaNi5-xg.x compound.. The smaller the shift of EF toward.hig.er energ. reg.on, the more stable the compound. will be. The increased.contribution of the Ni-d.g.-d.interactions near EF and.the low energ. metal-g.llium bond.ng.band. ind.cate that the compound. become more stable. The results are compared.with experimental d.ta and.d.scussed.in lig.t of previous stud.es.

Asymmetric three-phase cascad.ng.Trinary-d. source Multilevel Inverter which can achieve red.ced.harmonics and.superior root mean square (RMS) values of the output voltag. is proposed. This topolog. can achieve cascad.d.full brid.e inverter operation with d.ssimilar (unequal) d. Source and.it is fired.by using.variable frequency pulse with mod.lation technique as a switching.strateg.. This pulse wid.h mod.lation switching.strateg. has a newly ad.pted.multicarrier sing.e reference technique. The performance parameter factors like Form Factor (FF), Crest Factor (CF), Total Harmonic d.stortion (THd. and.fund.mental RMS output voltag. (VRMS) are estimated.by using.proposed.asymmetrical three-phase cascad.ng.multilevel inverter for several mod.lation ind.ces (0.8 - 1). The research stud. carries with MATLAB/SIMULINK based.simulation and.experimental results obtained.using.appropriate prototype (test board. to prove the viability of the proposed.concept.

Ozone has become one of the most important air pollution issues around.the world. This article applied.both O 3 /（NOy-NOx） and.H 2 O 2 /HNO 3 ind.cators to analyze the ozone sensitivity in urban and.rural areas of Shang.ai, with implementation of the MM5-CMAQ mod.ling.system in July, 2007. The meteorolog.cal parameters were obtained.by using.the MM5 mod.l. A reg.onal emission inventory with spatial and.temporal allocation based.on the statistical d.ta has been d.veloped.to provid. input emission d.ta to the MM5-CMAQ mod.ling.system. Results showed.that the ozone concentrations in Shang.ai show clear reg.onal d.fferences. The ozone concentration in rural areas was much hig.er than that in the urban area. Two ind.cators showed.that ozone was more sensitive to VOCs in urban areas, while it tend.d.to be NOx sensitive in rural areas of Shang.ai.

The runoff of the Huang.e contains a g.eat amount of suspend.d.load.and.forms the hig.-d.nsity und.rflows (hyperpycnal currents) at the river mouth. The sed.ments over the subaqneous d.lta are mainly transported.by the und.rflow. The sed.ment texture g.ad.ally g.t fining.seaward., which relates to the attenuation of the hyperpycnal currents and.hypopycnal plumes. Being.hyd.aulically equivalent to the med.um-silt-sized.quartz, which is the d.minant component in the sed.ments, the clastic mica concentrates on the d.lta. The maximum thickness of the subaqueous d.lta is about 16m and.the period.of accumulation lasted.from 12 to 16 years, therefore its sed.mentary rate rang.s from 110 to 130 cm/a.

Plant-pollinator in teractio ns have a fund.me ntal in fluence on flower evolution. Flower color sig.als are frequently tuned.to the visual capabilities of important pollinators such as either bees or bird., but far less is known about whether flower shape in fluences the choices of pollinators. We tested.European honeybee Apis mellifera pref ere nces using.novel achromatic (g.ay-scale) imag.s of 12 insect-pollinated.and.12 bird.pollinated.native Australian flowers in g.rmany;thus, avoid.ng.in flue nces of color, od.r, or prior experie nee. In d.pend. nt bees were tested.with a number of parameterized.imag.s specifically d.sig.ned.to assess pref ere nces for size, shape, brig.tness, or the number of flower-like shapes prese nt in an imag.. We show that honeybees have a pref ere nee for visiti ng.imag.s of in sect-polli nated.flowers and.such a pref ere nee is most-likely med.ated.by holistic in formati on rather than by in d.vid.al imag. parameters. Our results in d.cate an g.osperms have evolved.flower shapes which in fluence the choice behavior of importa nt pollinators, and.thus sug.est spatial achromatic flower properties are an important part of visual sig.aling.for plantpollinator in teractions.

The thermal ind.ced.topog.aphy chang. in a mod.l system consisting.of a polymer film on a Si substrate capped.by a thin metal layer has been stud.ed.by using.AFM. Reg.lar lateral patterns over larg. areas were observed.on the surface when the system was heated.to a sufficiently hig. temperature. 2d.FFT analysis to the AFM imag.s ind.cates that the patterns are isotropic and.have well d.fined.period.cities. The period.cities of the characteristic patterns are found.to d.pend.strong.y on the annealing.temperature. The stud. of the kinetics of the formation reveals that such a topog.aphy forms almost instantaneously once the critical temperature is reached. It is sug.ested.that this wave-like surface morpholog. is d.iven by the thermal expansion coefficient mismatch of the d.fferent layers. This method.for g.nerating.reg.lar wave-like patterns could.be used.as a g.neral method.for patterning.various org.nic materials into micro/nanostructures.
