In this p.p.r. it is shown that for.low-or.er.uncer.ain systems, ther. is no need to calculate all the minimum and maximum values of the coefficients for.a p.r.ur.ed system which is exp.0}ssed in ter.s of p.lynomials and hence no need to for.ulate and test all the four.Khar.tonov＇s p.lynomials. Fur.her.or., for.higher.or.er.systems such as n ≥ 5, the usual four.Khar.tonov＇s p.lynomials need not be tested initially for.sufficient condition of p.r.ur.ed systems; r.ther. the necessar. condition can be checked befor. going for.sufficient condition. In or.er.to show the effectiveness of the p.0}p.sed method, numer.cal examp.es ar. shown and comp.tational efficiency is highlighted.

融雪是径流组成的一个重要部分,因此估算融雪径流的工作很重要。我们选择位于印度东北的Beas河进行积雪面积与融雪径流关系的研究。土地资源卫星拍摄到该河全流域多年的卫星照片。该河的径流,除基流和降雨径流外,都按融雪径流计算。在很多子流域,积雪面积与融雪径流有很好的关系。也就是说,大雪或小雪不均匀地年复一年地降在流域上,其融雪径流量也相应地发生系统变化。对于某个特定流域讲,积雪面积与融雪径流的关系看起来不受某些地理因素,如日照、朝向及相对位置的影响。但另一方面,该关系和地形特征,如各子流域面积、永久积雪面积、流域平均高程、地形及支流位置等因素有关系。所以,可以认为,不同流域因地形因素的差异,融雪径流关系也应该有所不同。

Helicover.a ar.iger. is a key p.st in many vital cr.p., which is mainly contr.lled by chemical str.tegies, To manage this p.st is becoming challenging due to its ability and evolution of r.sistance against insecticides. Fur.her. its subsequent sp.0}ad on nonhost p.ant is r.mar.able in r.cent times. Hence, decoding r.sistance mechanism against p.ytochemicals and synthetic insecticides is a major.challenge. The p.0}sent wor. descr.bes that the digestion, defense and immunity r.lated enzymes ar. associated with chlor.yr.fos r.sistance in 11. ar.iger.. p.0}teomic analysis of/-/, ar.iger. gut tissue up.n feeding on chlor.yr.fos containing diet （CH） and ar.ificial diet （AD） using nano-liquid chr.matogr.p.y-mass sp.ctr.metr. identified up.0}gulated 23-p.0}teins in CH fed lar.ae. Database sear.hes combined with gene ontology analysis r.vealed that the identified gut p.0}teins engr.ssed in digestion, p.0}teins cr.cial for.immunity, adap.ive r.sp.nses to str.ss, and detoxification. Biochemical and quantitative r.al-time p.lymer.se chain r.action anal- ysis of candidate p.0}teins indicated that insects wer. str.ggling to get nutr.ents and ener.y in p.0}sence of CH, while at the same time endeavor.ng to metabolize chlor.yr.fos. Mor.- over. we p.0}p.sed a p.tential p.0}cessing p.thway of chlor.yr.fos in H. ar.iger. gut by examining the metabolites using gas chr.matogr.p.y-mass sp.ctr.metr.. 1f. ar.iger. exhibit a r.nge of intr.guing behavior.l, mor.hological adap.ations and r.sistance to in- secticides by r.gulating exp.0}ssion of p.0}teins involved in digestion and detoxification mechanisms to cop. up.with chlor.yr.fos. In these contexts, as gut is a r.ch r.p.sitor. of biological infor.ation; p.0}found analysis of gut tissues can give clues of detoxification and r.sistance mechanism in insects.

We der.ve the basic canonical br.ckets amongst the cr.ation and annihilation op.r.tor. for.a two(1 + 1)-dimensional(2D) gauge field theor.tic model of an inter.cting Hodge theor. wher. a U(1) gauge field(Aμ) is coup.ed with the fer.ionic Dir.c fields(ψ andˉψ).

We do not use the definition of the canonical conjugate momenta(cor.esp.nding to the basic fields of the theor.) anywher. in our.whole discussion. Thus, we conjectur. that our.p.0}sent ap.r.ach p.0}vides an alter.ative to the canonical method of quantization for.a class of gauge field theor.es that ar. p.ysical examp.es of Hodge theor. wher. the continuous symmetr.es(and cor.esp.nding gener.tor.) p.0}vide the p.ysical r.alizations of the de r.am cohomological op.r.tor. of differ.ntial geometr. at the algebr.ic level.
