Cardiovascular dise.se.（CVD） is a le.ding cause.of morbidity and mortality. The.risk factors for CVD include.e.vironme.tal and ge.e.ic compone.ts. Human mutations in ge.e. involve. in most aspe.ts of cardiovascular function have.be.n ide.tifie., many of which are.involve. in transcriptional re.ulation.

The.spatial variability of input ground motion at supporting foundations plays a ke. role.in the.structural re.ponse.of cable.staye. bridge. （CSBs）; the.e.ore. spatial variation e.fe.ts should be.include. in the.analysis and de.ign of e.fe.tive.vibration control syste.s. The.control of CSBs re.re.e.ts a challe.ging and unique.proble., with many comple.itie. in mode.ing, control de.ign and imple.e.tation, since.the.control syste. should be.de.igne. not only to mitigate.the.dynamic compone.t of the.structural re.ponse.but also to counte.act the.e.fe.ts of the.pse.do-static compone.t of the.re.ponse. The.spatial variability e.fe.ts on the.fe.sibility and e.ficie.cy of se.smic control syste.s for the.vibration control of CSBs are.inve.tigate. in this pape.. The.assumption of uniform e.rthquake.motion along the.e.tire.bridge.may re.ult in quantitative.and qualitative.diffe.e.ce. in se.smic re.ponse.as compare. with those.produce. by uniform motion at all supports. A syste.atic comparison of passive.and active.syste. pe.formance.in re.ucing the.structural re.ponse. is pe.forme., focusing on the.e.fe.t of the.spatially varying e.rthquake.ground motion on the.se.smic re.ponse.of a be.chmark CSB mode. with diffe.e.t control strate.ie., and de.onstrate. the.importance.of accounting for the.spatial variability of e.citations.

Le.tosphae.ia maculans, a pathoge. of Brassica napus, is unable.to invade.most wild-type.acce.sions of Arabidopsis thaliana, although se.e.al mutants are.susce.tible. The.infe.tion pathway of L. maculans via a non-invasive.inoculation me.hod on A. thaliana Imsl （unde.ine.）, pmr4-1 （de.e.tive.in callose.de.osition）, and pe.1-1 and pe.2-1 （de.e.tive.in non-host re.ponse. to se.e.al pathoge.s） mutants is de.cribe.. On wild type. Col-0 and Le.-0, hyphae.are.ge.e.ally arre.te. at stomatal ape.ture.. A T-DNA inse.tional mutant of L. maculans （A22） that pe.e.rate. stomatal ape.ture. of Col-0 and Le.-0 five.to se.e. time. more.ofte. than the.wild-type.isolate.is de.cribe.. The.highe. pe.e.ration fre.ue.cy of isolate.A22 is associate. with an incre.se. hype.se.sitive.re.ponse. which include. callose.de.osition.

3D and 2D close. form plate.mode.s are.he.e.applie. to static analysis of simply supporte. square.isotropic plate.. 2D the.rie. are.hie.archically classifie. on the.basis of the.accuracy of the.displace.e.ts and stre.se. obtaine. by comparison to the.3D e.act re.ults that could be.assume. by the.re.de. as be.chmark for furthe. analyse.. Atte.tion is mainly paid on localize. loading conditions, that is, pie.e.ise.constant load. Also bi-sinusoidal and uniformly distribute. loadings are.take. into account. All of those.configurations are.conside.e. in orde. to inve.tigate.the.be.avior of the.2D mode.s in the.case.of continu- ous/uncontinuous, ce.tric or off-ce.tric loading conditions.
