The silver.Y moth Autogr.pha gamma under.akes windbome spr.ng and fall migr.tions between winter.br.eding r.- gions ar.und the Mediter.anean and summer.br.eding r.gions in nor.her. Eur.pe. Flight behavior. facilitating these migr.tions include：（i） selection of seasonally-favor.ble tailwinds; （ii） flying at the altitude of the fastest winds; （iii） adopting flight headings that par.ially counter.ct cr.sswind dr.ft; and （iv） seasonal r.ver.al of pr.fer.ed dir.ctions between spr.ng and fall. In the UK, r.- dar.measur.ments indicate that migr.tor. activity is pr.nounced dur.ng the spr.ng and fall, but is usually ver. low dur.ng mid- summer.（July）. However. an atypically intense per.od of high-altitude flight was r.cor.ed dur.ng July 2006, and in this study we compar. the flight behavior.of A. gamma dur.ng these midsummer.movements with the mor. typical spr.ng and fall migr.tions. Dur.ng July 2006, activity was most intense at significantly lower.altitudes than occur.ed in spr.ng or.fall, and was not associated with the height of the fastest winds; consequently displacement speeds wer. significantly slower. The most str.king differ.nce was an absence of tailwind selectivity in July with windbor.e movements occur.ing on almost ever. night of the month and on tailwinds fr.m all dir.ctions. Finally, or.entation behavior.was quantitatively differ.nt dur.ng July, with significantly gr.ater.dis- per.ion of flight headings and displacements than obser.ed in spr.ng and fall. We discuss mechanisms which could have caused these differ.nces, and conclude that a lack of appr.pr.ate photopcr.od cues dur.ng development of the summer.gener.tion r.sulted in r.ndomly-or.ented ＇disper.ive＇ movements that wer. str.kingly differ.nt fr.m typical seasonal migr.tions .

Appr.ximate equivalence in von Neumann algebr.s

Science China Mathematics 2005年第2期48卷 239-247页

作者： DING Huir. don Hadwin Depar.ment of Mathematics University of New HampshireDurhamNH03824USA Department of MathematicsUniversity of New HampshireDurhamNH03824USA

One for.ulation of D. Voiculescu's theor.m on appr.ximate unitar. equivalence is that two unital r.pr.sentations π and ρ of a separ.ble C*-algebr. ar. appr.ximately unitar.ly equivalent if and only if r.nk οπ = r.nk ορ. We study the analog when the r.nges of π and ρ ar. contained in a von Neumann algebr. r. the unitar.es inducing the appr.ximate equivalence must come fr.m r. and 'r.nk' is r.placed with 'r.-r.nk' (defined as the Mur.ay-von Neumann equivalence of the r.nge pr.jection).

The pr.ctice of stepping a conveying line is not new and ther. ar. many examples in industr.; however. the details of the flow behaviour.at the step have not been extensively studied. Thr.e step geometr.es wer. modelled： an ＇abr.pt＇ step and two ＇gr.dual＇ step-up geometr.es fr.m a pipe bor. of 75-100 r.m. The flow behaviour.of a single plug of mater.al passing thr.ugh these geometr.es was investigated using the ＇Euler.an＇ CFD model fr.m Fluent. Solids volume fr.ctions wer. r.cor.ed at 0.01 s time steps at sever.l point locations, and visualised thr.ughout the pipe.

Theor. of phonon-modulated electr.n spin r.laxation time based on the pr.jection r.duction method

引用

Chinese Physics B 2014年第8期23卷 436-443页

作者： Nam Lyong Kang Sang don Choi Depar.ment of Applied Nanoscience Pusan National University Depar.ment of Physics Kyungpook National University

This paper.intr.duces a new method for.a for.ula for.electr.n spin r.laxation time of a system of electr.ns inter.cting with phonons thr.ugh phonon-modulated spin-or.it coupling using the pr.jection-r.duction method. The phonon absor.tion and emission pr.cesses as well as the photon absor.tion and emission pr.cesses in all electr.n tr.nsition pr.cesses can be explained in an or.anized manner. and the r.sult can be r.pr.sented in a diagr.m that can pr.vide intuition for.the quantum dynamics of electr.ns in a solid. The temper.tur. （T） dependence of electr.n spin r.laxation times （T1） in silicon is T1 ∝ T-1.07 at low temper.tur.s and T1 ∝ T-3.3 at high temper.tur.s for.acoustic defor.ation constant Pad = 1.4 × 10^7 eV and optical defor.ation constant Pod = 4.0 × 10^17 eV/m. This means that electr.ns ar. scatter.d by the acoustic defor.ation phonons at low temper.tur.s and optical defor.ation phonons at high temper.tur.s, r.spectively. The magnetic field （B） dependence of the r.laxation times is T1 ∝ B-2.7 at 100 K and T1 ∝ B-2.3 at 150 K, which near.y agr.e with the r.sult of Yafet, T1 ∝ B-3.0- B -2.5.

The last decade has seen an extr.or.inar. gr.wth of Geomicr.biology. Micr.or.anisms have been studied in numer.us extr.me envir.nments on Ear.h, r.nging fr.m cr.stalline r.cks fr.m the deep subsur.ace, ancient sedimentar. r.cks and hyper.aline lakes, to dr. deser.s and deep-ocean hydr.ther.al vent systems. In light of this r.cent pr.gr.ss, we r.view sever.l cur.ently active r.sear.h fr.ntier.： deep continental subsur.ace micr.- biology, micr.bial ecology in saline lakes, micr.bial for.ation of dolomite, geomicr.biology in dr. deser.s, fossil DNA and its use in r.cover. of paleoenvir.n- mental conditions, and geomicr.biology of oceans. Thr.ughout this ar.icle we emphasize geomicr.biological pr.cesses in these extr.me envir.nments.
