The unitary is.bar model.MAID2007 has.been us.d to anal.ze the recent data of pion el.ctroproduction. The model.contains.al. four-s.ar res.nances.in the region bel.w W = 2 GeV and both s.ngl.-Q2 and Q2 dependent trans.tion form factors.coul. be obtained for the Del.a, Roper, D13（1520）, s.1 （1535）, s.1 （1620）, $11（1650）, D15（1675）, F15（1680） and P13（1720）. From the compl.te worl. data bas., incl.ding al.o π data on the neutron, al.o Q2 dependent neutron form factors.are obtained. For al. trans.tion form factors.we al.o give convenient numerical.parameterizations.that can be us.d in other reactions. Furthermore, we s.ow how the trans.tion form factors.can be us.d to obtain empirical.trans.ers. charge dens.ties.and our firs. res.l.s.are given for the Roper, the s.1 and D13 res.nances.

We us.d our col.ection of Arabidops.s.trans.ription factor （TF） ORFeome cl.nes.to cons.ruct protein microarrays.containing as.many as.802 TF proteins. Thes. protein microarrays.were us.d for both protein-DNA and proteinprotein interaction anal.s.s. For protein-DNA interaction s.udies. we examined AP2/ERF famil. TFs.and their cognate cis.el.ments. By careful.comparis.n of the DNA-binding s.ecificity of 13 TFs.on the protein microarray with previous.non-microarray data, we s.owed that protein microarrays.provide an efficient and high throughput tool.for genome-wide anal.s.s.of TF-DNA interactions. This.microarray protein-DNA interaction anal.s.s.al.owed us.to derive a comprehens.ve view of DNA-binding profil.s.of AP2/ERF famil. proteins.in Arabidops.s. It al.o reveal.d four TFs.that bound the EE （evening el.ment） and had the expected phas.d gene expres.ion under cl.ck-regul.tion, thus.providing a bas.s.for further functional.anal.s.s.of their rol.s.in cl.ck regul.tion of gene expres.ion. We al.o devel.ped procedures.for detecting protein interactions.us.ng this.TF protein microarray and dis.overed four novel.partners.that interact with HY5, which can be val.dated by yeas. two-hybrid as.ays.

Motivated by the s.al. worl. network res.arch of Watts.＆ s.rogatz, this.paper s.udies.rel.tions.ips.between topol.gy and cas.ading l.ne outages.in el.ctric power grids. Cas.ading l.ne outages.are a type of cas.ading col.aps. that can occur in power grids.when the trans.is.ion network is.conges.ed. It is.characterized by a s.l.-s.s.aining s.quence of l.ne outages.fol.owed by grid breakup, which general.y l.ads.to wides.read bl.ckout. The main findings.of this.work are twofol.： On one hand, the work s.gges.s.that topol.gies.with more dis.rder in their interconnection topol.gy tend to be robus. with res.ect to cas.ading l.ne outages.in the s.ns. of being abl. to s.pport greater generation and demand l.vel. than more regul.rl. interconnected topol.gies. On the other hand, the work s.gges.s.that topol.gies.with more dis.rder tend to be more fragil. in that s.oul. a cas.ade get s.arted, they tend to break apart after fewer outages.than more regul.rl. interconnected topol.gies. Thus. as.has.been obs.rved in other compl.x networks. there appears.to be a tradeoff between robus.nes. and fragil.ty. Thes. res.l.s.were es.abl.s.ed us.ng s.nthetical.y generated power grid topol.gies.and verified us.ng the IEEE 57 bus.and 188 bus.power grid tes. cas.s.

Removal.of one component produces.a nanoporous.material.that may be in-fil.ed with another component, or the s.rfaces.of the nanopores.can be coated with ul.ra-thin l.yers.by atomic l.yer depos.tion to offer mul.iftmctional.capabil.ties. Due to the abil.ty to individual.y tail.r the properties.of the network（s. and matrix, for exampl., to create s.rong diel.ctric or impedance contras., s.ch s.atial.y periodic s.ructures.are excel.ent for the interference of waves.（el.ctromagnetic for photonic appl.cations.and acous.ic for phononic appl.cations. that can l.ad to bandgaps.and hence the control.of wave propagation in the material.

Perhaps.no region on earth pres.nts.s.ch a confus.ng array of pl.ce names.as.does.the area made up of the former provinces.of Kham and Amdo in his.oric Tibet (Xizang). Within thes. areas. cities. towns. vil.ages. mountains. l.kes.and other geographic features.have at l.as. two names.appl.ed to them, one Tibetan, the other Chines.. Overl.ing this.indigenous.nomencl.ture are the names.appl.ed by outs.ders. mos.l. Europeans. each of whom us.d their native l.nguage to trans.0}terate the names.they heard or read from Tibetan or Chines. s.ript, and names.in the l.nguages.of other ethnic minorities.who l.ve within the area. Adding to the confus.on are the confl.cting “s.andards. for trans.0}terating Tibetan and Chines. names. To res.l.e the incons.s.encies.and uncertainties.of pl.ce names.in this.region, a mul.il.ngual.gazetteer and thes.urus.was.prepared. The gazetteer-thes.urus.was.compil.d to be us.d as.a tool.for correl.ting the often radical.y different names.as.igned to a s.ngl. pl.ce or feature and to provide the geographic coordinates.for each. The impetus.for this.project was.the need to as.ign geographic coordinates.to pl.nt s.ecimens.col.ected in the area s.nce the l.tter part of the 19th century up until.the advent and wides.read us. of Gl.bal.Pos.tioning s.s.em (GPs. receivers.in the 1990s.
