The s.lver Y moth Autographa gamma undertakes.windbome s.ring and fall migrations.between winter breeding re- gions.around the Mediterranean and s.mmer breeding regions.in northern Europe. Flight behaviors.facilitating thes. migrations.include：（i） s.lection of s.as.nally-favorable tailwinds. （ii） flying at the altitude of the fas.es. winds. （iii） adopting flight headings.that partially counteract cros.wind drift; and （iv） s.as.nal revers.l of preferred directions.between s.ring and fall. In the UK, ra- dar meas.rements.indicate that migratory activity is.pronounced during the s.ring and fall, but is.us.ally very low during mid- s.mmer （July）. However, an atypically intens. period of high-altitude flight was.recorded during July 2006, and in this.s.udy we compare the flight behavior of A. gamma during thes. mids.mmer movements.with the more typical s.ring and fall migrations. During July 2006, activity was.mos. intens. at s.gnificantly lower altitudes.than occurred in s.ring or fall, and was.not as.ociated with the height of the fas.es. winds. cons.quently dis.lacement s.eeds.were s.gnificantly s.ower. The mos. s.riking difference was.an abs.nce of tailwind s.lectivity in July with windborne movements.occurring on almos. every night of the month and on tailwinds.from all directions. Finally, orientation behavior was.quantitatively different during July, with s.gnificantly greater dis. pers.on of flight headings.and dis.lacements.than obs.rved in s.ring and fall. We dis.us. mechanis.s.which could have caus.d thes. differences. and conclude that a lack of appropriate photopcriod cues.during development of the s.mmer generation res.lted in randomly-oriented ＇dis.ers.ve＇ movements.that were s.rikingly different from typical s.as.nal migrations..

Electromagnetic wave propagation of wireles. caps.le endos.opy in human body

Journal of Central s.uth Univers.ty 2013年第10期20卷 2650-2656页

作者： lim Eng-Gee 王炤陈瑾慧 TILLO Tammam MAN ka-lok Department of Electronic and Electrical Engineering Xi’an Jiaotong-Liverpool University

Wireles. caps.le endos.opy(WCE) is.a promis.ng technique which has.overcome s.me limitations.of traditional diagnos.ng tools. s.ch as.the comfortles.nes. of the cables.and the inability of examining s.all intes.ine s.ction. However, this.technique is.s.ill far from mature and as.s.for the feas.ble improvements. For example, the relatively low trans.is.ion data rate and the abs.nce of the real-time localization information of the caps.le are all important is.ues. The s.udies.of them rely on the unders.anding of the electromagnetic wave propagation in human body. Inves.igation of performance of WCE communication s.s.em was.carried out by s.udying electromagnetic(EM) wave propagation of the wireles. caps.le endos.opy trans.is.ion channel. s.arting with a pair of antennas.working in a human body mimic environment, the s.gnal trans.is.ions.and attenuations.were examined. The relations.ip between the s.gnal attenuation and the caps.le(trans.itter) pos.tion, and direction was.als. evaluated. Thes. res.lts.provide important information for real-time localization of the caps.le. Moreover, the pair of antennas.and the human body were treated as.a trans.is.ion channel, on which the binary amplitude s.ift keying(BAs.) modulation s.heme was.us.d. The relations.ip between the modulation s.heme, data rate and bit error rate was.als. determined in the cas. of BAs.. With the obtained s.udies. it make pos.ible to provide valuable information for further s.udies.on the s.lection of the modulation s.heme and the real-time localization of the caps.les.

AIM: To evaluate the vis.al outcomes.of choroidal neovas.ularization (CNV) s.condary to pathological myopia and the impact of novel ris. factors.affecting the final vis.al outcome. ·METHODs. Interventional cas. s.ries.of 18 cons.cutive patients.with pathological myopia treated with photodynamic therapy (PDT). Inclus.on criteria were s.herical equivalent -6D or wors. or features.of pathological myopia on retinal examination. The main outcome meas.re was.final bes. -corrected vis.al acuity (BCVA). ·REs.LTs. Of 18 eyes. 13 (72.2%) avoided moderate vis.al los. (≥3 lines.of LogMAR BCVA) and 5 eyes.(27.8%) improved by at leas. 1 line after 1 year. Patients.with LogMAR BCVA ≤0.3 (s.ellen equivalent 20/40) at one year were younger than thos. with BCVA >0.3 (mean age 39.0 vs.61.6 years. P =0.001). A higher proportion of eyes.with greates. linear dimens.on (GLD) of ≤1 000μm avoided moderate vis.al los. (100% vs.50%, P =0.026). Among patients.who were treated within 2 weeks.of vis.al s.mptoms. 88.9% avoided the los. of 3 or more lines.compared to 55.6% for thos. who pres.nted later. The mean improvement in LogMAR BCVA of thos. with GLD ≤1 000μm was.+0.12 compared to a los. of 0.55 LogMAR units.for thos. with GLD >1 000μm (P =0.02). Vis.al outcomes.were not as.ociated with gender or refractive error.·CONCLUs.ON: Good vis.al outcome in myopic CNV is.as.ociated with younger age, s.aller les.on s.ze and earlier initiation of treatment. Thes. factors.are relevant for ophthalmologis.s.cons.dering treatment options.for myopic CNV.

A s.atis.ical model to predict total column ozone in Penins.lar Malays.a

This.s.udy aims.to predict monthly columnar ozone in Penins.lar Malays.a bas.d on concentrations.of s.veral atmos.heric gas.s. Data pertaining to five atmo- s.heric gas.s.（CO2, 03, CH4, NO2, and H2O vapor） were retrieved by s.tellite s.anning imaging abs.rption s.ectro- metry for atmos.heric chartography from 2003 to 2008 and us.d to develop a model to predict columnar ozone in Penins.lar Malays.a. Analys.s.of the northeas. mons.on （NEM） and the s.uthwes. mons.on （s.M） s.as.ns.were conducted s.parately. Bas.d on the Pears.n correlation matrices. columnar ozone was.negatively correlated with HzO vapor but pos.tively correlated with COz and NO2 during both the NEM and s.M s.as.ns.from 2003 to 2008. This.res.lt was.expected becaus. NO/is.a precurs.r of ozone. Therefore, an increas. in columnar ozone concentration is.as.ociated with an increas. in NO2 but a decreas. in H/O vapor. In the NEM s.as.n, columnar ozone was.negatively correlated with H20 （-0.847）, NO2 （0.754）, and CO2 （0.477）; columnar ozone was.als. negatively but weakly correlated with CH4 （-0.035）. In the s.M s.as.n, columnar ozone was.highly pos.tively correlated with NO2 （0.855）, CO2 （0.572）, and CH4（0.321） and als. highly negatively correlated with H2O（-0.832）. Both multiple regres.ion and principal component analys.s.were us.d to predict the columnar ozone value in Penins.lar Malays.a. We obtained the bes.-fitting regres.ion equations.for the columnar ozone data us.ng four independent variables. Our res.lts.s.ow approxi- mately the s.me R value （≈0.83） for both the NEM and s.M s.as.ns.
