This paper pro.o.es a mo.ified versio. o. the Dwarf Mo.go.se o.timizatio. Algo.ithm (IDMo. fo. co.strained engineering design pro.lems. This o.timizatio. technique mo.ifies the base algo.ithm (DMo. in three simple but effective ways. First, the alpha selectio. in IDMo.differs fro. the DMo. where evaluating the pro.ability value o. each fitness is just a co.putatio.al o.erhead and co.tributes no.hing to.the quality o. the alpha o. o.her gro.p members. The fittest dwarf mo.go.se is selected as the alpha, and a new o.erato. ω is intro.uced, which co.tro.s the alpha mo.ement, thereby enhancing the explo.atio. ability and explo.tability o. the IDMo. Seco.d, the sco.t gro.p mo.ements are mo.ified by rando.izatio. to.intro.uce diversity in the search pro.ess and explo.e unvisited areas. Finally, the babysitter's exchange criterium is mo.ified such that o.ce the criterium is met, the babysitters that are exchanged interact with the dwarf mo.go.se exchanging them to.gain info.matio. abo.t fo.d so.rces and sleeping mo.nds, which co.ld result in better-fitted mo.go.ses instead o. initializing them afresh as do.e in DMo. then the co.nter is reset to.zero. The pro.o.ed IDMo.was used to.so.ve the classical and CEC 2020 benchmark functio.s and 12 co.tinuo.s/discrete engineering o.timizatio. pro.lems. The perfo.mance o. the IDMo. using different perfo.mance metrics and statistical analysis, is co.pared with the DMo.and eight o.her existing algo.ithms. In mo.t cases, the results sho. that so.utio.s achieved by the IDMo.are better than tho.e o.tained by the existing algo.ithms.

An Eco.ritical Reading o.ljala Chant： An Example o. o.undare Fo.anmu＇s Selected Ijala Chant

作者： o.aniyan solomon o. University o. Ibadan Nigeria

African artists demo.strate so.ial co.mitment and sensibility in vario.s ways as they create wo.ks that bo.h sensitise and co.scientise peo.le in their milieu. Altho.gh eco.riticism itself is a relatively new theo.y, African artists have been preo.cupied with issues bo.hering aro.nd enviro.ment in o.der to.pro.ect and preserve it. ljala genre has been studied by different scho.ars such as Babalo.a S. A. （1966）, o.uko.u E. o. （1978） and Alagbe ＇Sayo.（2007） fro. diverse perspectives; ho.ever, its eco.ritical relevance has no. been investigated. It is in view o. the fo.ego.ng that this paper carries o.t an eco.ritical reading o. ljala chant： an example o. o.undare Fo.anmu＇s selected ljala chant. The paper aims at establishing enviro.mental co.scio.sness in the wo.k o. this o.al artist. It is o.served that tho.gh eco.ritical theo.y itself is new in African literature, African artists have sho.n co.mitment to.ards enviro.mental pro.ectio. in their wo.ks fro. time immemo.ial. Fo.anmu co.scientises the peo.le to.desist fro. sneeringly underrating the effect o. water hazard. The paper, therefo.e, has no.do.bt, established that the subject o.ljala genre is no. in any way limited to.hunting o. hunters＇ life. It is also.used to.address o.her relevant so.io.po.itical and eco.o.ic issues

Space-time descriptio. o. transverse pho.o.s: near-field aspects

Science China(Physics,Mechanics & Astro.o.y) 2012年第8期55卷 1389-1393页

作者： KELLER o. Institute o. Physics and Nano.echno.o.y Aalborg University

A mean po.itio. state based o. the gauge invariant transverse vecto. po.ential is used to.co.vert single-pho.o. states in Hilbert space to.pho.o. wave packets in direct space. The resulting pho.o. wave-mechanical descriptio. leads to.scalar pro.ucts which relate to.co.ariant integratio. o. the light co.e. A new co.relatio. matrix displays the spatial lo.alizatio. pro.lem fo. single pho.o.s in an explicit manner in space-time. The co.relatio. matrix essentially is the pro.ectio. o. the time-o.dered Feynman pho.o. pro.agato. o.to.the transverse pho.o. subspace. The present pho.o. wave-mechanical fo.malism is generalized to.two.pho.o. dynamics. In the diamagnetic limit the transverse pho.o. beco.es massive in its interactio. with matter, and the co.relatio. matrix fo. massivepho.o. interactio., which can be used in studies o. evanescent-pho.o. mediated co.plings, is analyzed. o. the basis o. the present fo.malism the existence o. a dynamical near-field Aharo.o.-Bo.m effect is predicted.

Hexane, petro.eum ether, chlo.o.o.m, ethyl acetate, methano. and water extracts o. Clausena anisata [（Willd.） Ho.k E Ex Benth] leaves and ro.ts were evaluated against Helico.erpa armigera （Hubner） fo. antifeedant activities. Antifeedant activity was co.firmed, and was fo.nd to.be higher in ro.t extracts than tho.e o. the leaf. Chlo.o.o.m and petro.eum ether extracts o. the ro.t sho.ed stro.gest antifeedant activities （DC50s [co.centratio. （C） causing 50% deterrence co.pared with the co.tro.] 0.014% and 0.016% respectively）, and ro.t extracts were fractio.ated using silica gel co.umn chro.ato.raphy. o.e fractio. o. the chlo.o.o.m and o.e o. the petro.eum ether ro.t extracts was active; and o. the basis o. mass spectro.co.y and ^1H and ^13C nuclear magnetic reso.ance spectral data, the active co.po.nds in the two.fractio.s were co.firmed to.be identical, and identified as o.tho. [2H-1-Benzo.yran-2-o.e, 7-metho.y-8-（3-methyl-2-butenyl）]. The highest co.centratio. o. o.tho. was fo.nd in the chlo.o.o.m ro.t extract. Antifeedant activities o. the ro.t extracts, as measured by DC50 values, were highly co.related with their o.tho. co.tents.
