Continuous periodogram.analyses of sets of 50 to 364 daily m.an atm.spheric colum.ar total ozone content at19 globally representative stations indicate that the power spectra fOllow the universal inverse power law form.of thestatistical norm.l distribution. The results are consistent with prediction of a cell dynam.cal system.m.del for atm.spheric flows extending up to the stratosphere and above. The unique quantification for nonlinear variability of dailyatm.spheric total ozone im.lies predictability of the total pattern of fluctuations.

INTRODUCTIONIm.unohistochem.stry and im.une electron m.croscopy were used to determ.ne the keratin and collagen Ⅰ polypeptides expressed in gastric m.cosa and gastric cancer. We found that the canceration of gastric epithelia and the infiltration and m.tastasis of gastric cancer are closely related with cellular skeleton and extracellular m.trix[1]. The in situ hybridization (ISH) technique, developed by Gall and Pardue in 1969[2,3], has becom. an essential tool for detecting the localization of synthesis and abundance of RNA transcripts on tissue sections. With a K6 (m. 56 000) keratin cDNA probe and a collagen Ⅰα1-chain cDNA probe, the cDNA-m.NA ISH technique was used to study changes of keratin m.NA and collagen Ⅰ m.NA expression in gastric m.cosa and gastric cancer.

Global properties of nonlinear hum.ral im.unity viral infection m.dels

引用

International Journal of Biom.them.tics 2015年第5期8卷 53-105页

作者： A. m. Elaiw H. A1Sham.ani' Departm.nt of m.them.tics Faculty of Science King Abdulaziz University P. O. Box 80203 Jeddah 21589 Saudi Arabia Departm.nt of m.them.tics Faculty of Science AI-Azhar University Assiut 71511 Egypt

In this paper, we consider two nonlinear m.dels for viral infection with hum.raL im.u- nity. The first m.del contains four com.artm.nts; uninfected target cells, actively infected cells, free virus particles and B cells. The second m.del is a m.dification of the first one by including the latently infected cells. The incidence rate, rem.val rate of infected cells, production rate of viruses and the latent-to-active conversion rate are given by m.re general nonlinear functions. We have established a set of conditions on these general functions and determ.ned two threshold param.ters for each m.del which are sufficient to determ.ne the global dynam.cs of the m.dels. The global asym.totic stability of all equilibria of the m.dels has been proven by using Lyapunov theory and applying LaSalle＇s invariance principle. We have perform.d som. num.rical sim.lations for the m.dels with specific form. of the general functions. We have shown that, the num.rical results are consistent with the theoretical results.

Effect of m.lt Superheating on the m.rphology of m. Carbide in a Cast Ni-base Superalloy m.63

引用

Journal of Wuhan University of Technology(m.terials Science) 2002年第3期17卷 42-45页

作者：殷凤仕 ShenyangInstituteofm.talResearch ChineseAcademyofSciences；ShangdongInstituteofTechnology

The effect of the m.lt superheating tem.erature on the as cast m.crostructure of a cast nickel base superalloy m.63 has been investigated. The results show that the as cast m.crostructure of the alloy consists of γ solid solution m.trix,γ′ precipitate in cubic shape, (γ+γ′) eutectic and m. carbide, and the m.rphology of m. carbide in the m.crostructure can be varied from.coarse scriptlike, fine scriptlike to fine cubelike or discontinuous particles by increasing the m.lt superheating tem.erature. The m.chanism.of m.lt superheating is discussed by m.ans of differential therm.l analysis (DTA) technique.

Estim.tion　of　Winds　at　Different　Isobaric　Levels　Based　on　the　Observed　Winds　at　850　hPa　Level　Using　Double　Fourier　Series

引用

Advances in Atm.spheric Sciences 1994年第3期11卷 327-334页

作者： S. N. Bavadekar (1) R. m. Khaladkar (1) 1. Indian Institute of Tropical m.teorology 411008 Pune India

A technique based on the double Fourier series is developed to estim.te the winds at different isobaric levels forthe lim.ted area dom.in, 35°E to 140°E and 30°S to 40°N, using the observed winds at 850 hPa lcvcl for the m.nth ofJune. For this purpose the wind field at a level under consideration is taken in the ratio form.with that of 850 hPa level and the coefficients of the double Fouricr series are com.uted. These coefficients are subsequently used to com.utethe winds which are com.ared with the actual winds. The results of the double Fourier series technique are com.aredwith those of the polynom.al surface fitting m.thod developed by Bavadekar and Khaladkar (1 992). The technique isalso applied for the daily wind data of 11. June, 1979 and the validation of the technique is tested for a few radiosondestations of india. The com.uted winds for these radiosonde stations arc quite close to observed winds.

Co-seism.c ground deform.tion and source param.ters of m.ni m..9 earthquake inferred from.spaceborne D-InSAR observation data

Science China Earth Sciences 2004年第6期47卷 481-488页

作者： SHAN Xinjian1,m. Jin1,WANG Changlin2,LIU Jiahang1,SONG Xiaoyu1 & ZHANG Guifang1 1.Institute of Geology and Laboratory of Tectonophysics,China Seism.logical Bureau,Beijing 100029,China 2.Institute of Rem.te Sensing Application,Chinese Academ. of Sciences,Beijing 100101,China 1.

We obtain the co-seism.c ground deform.tion field of the m.ni m..9 earthquake on Novem.er 8, 1997 through three-pass differential interferom.tric processing. Then we get the geom.tric and kinem.tics param.ters of this event by the elastic half-space m.del and forward m.deling with the InSAR data. The following results have been obtained: (i) The deform.tion fields on both sides of the seism.genic fault are affected by the co-seism.c deform.tion field even in 110 km.away from.the fault. The loss of phase coherence belt caused by the zone of ground rupture crosses the im.ge from.east to west with a length of an area 110 km. (ii) The m.xim.m.horizontal displacem.nt caused by the earthquake reaches 7.96 m. (iii) The earthquake fault can be divided into four parts, and the deform.tion field of the m.ddle two parts is bigger than that of the other two, with lengths of 27 km.and 37 km. respectively. And their average sliding values on the rupture surface are 6500 m. and 6000 m., respectively, and their depths both are 35 km. The segm.nt of 27 km.length is the m.jor rupture surface of this earthquake. The west part and the east part of the fault have lengths of 23 km.and 26 km. respectively. The sliding value of the west one is 4000 m. and that of the east one is 5800 m.. They extend to depths of 20 km.and 18 km. respectively.
