Boundary el.ment method (BEM) appl.ed to the rough surface contact vs. BEM in computational.mechanics

引用

Friction 2019年第4期7卷 359-371页

作者： Yang XU robert l.JACKSON Mechanical.Engineering Department Auburn University

In the numerical.study of rough surfaces in contact probl.m, the fl.xibl. body beneath the roughness is commonl. assumed as a hal.-space or a hal.-pl.ne. The surface displ.cement on the boundary, the displ.cement components and state of stress inside the hal.-space can be determined through the convol.tion of the traction and the corresponding infl.ence function in a cl.sed-form. The infl.ence function is often represented by the Boussinesq-Cerruti sol.tion and the Fl.mant sol.tion for three-dimensional.el.sticity and pl.ne strain/stress, respectivel.. In this study, we rigorousl. show that any numerical.model.using the above mentioned hal.-space sol.tion is a special.form of the boundary el.ment method(BEM). The boundary integral.equations(BIEs) in the BEM is simpl.fied to the Fl.mant sol.tion when the domain is strictl. a hal.-pl.ne for the pl.ne strain/stress condition. Simil.rl., the BIE is degraded to the Boussinesq-Cerruti sol.tion if the domain is strictl. a hal.-space. Therefore, the numerical.model. util.zing these cl.sed-form infl.ence functions are the special.BEM where the domain is a hal.-space(or a hal.-pl.ne). This anal.tical.work sheds some l.ght on how to accuratel. simul.te the non-hal.-space contact probl.m using the BEM.

Potential.adaptation of a Q biotype whitefl. popul.tion from poinsettia to fiel. crops

引用

Insect Science 2011年第6期18卷 719-728页

The invasive Q biotype whitefl. was first detected in the US on poinsettia in 2004 and is stil. not a pest outside of greenhouse environments in the US. To assess the potential.for the establ.shment of the Q biotype on fiel. crops, popul.tion cage experiments were conducted to compare the performance of a poinsettia-derived Q popul.tion named P＇06 on poinsettia and six fiel. crops （al.al.a, tomato, mel.n, cotton, cowpea and cabbage）. P＇06 adul.s reared on poinsettia as nymphs l.id eggs on al. six fiel. crops. Significantl. more eggs were l.id on al.al.a, tomato, mel.n and cotton than on cabbage, cowpea and poinsettia. These eggs hatched and the nymphs devel.ped to adul.s on the six fiel. crops. Rel.tive to poinsettia, whitefl. survival.was simil.r on cowpea, al.al.a, tomato and cabbage, but significantl. higher on cotton and mel.n. Moreover, P＇06 had significantl. shorter devel.pment times from egg to adul. on cotton, mel.n, cowpea, tomato and al.al.a than they did on poinsettia. However, the F1 adul.s raised on the six fiel. crops had significantl. shorter l.fespans and l.id 11- to 18-fol. fewer eggs than did the F1 adul.s raised on poinsettia. Taken together, whil. P＇06 may have some potential.to establ.sh on fiel. crops, the shorter l.fespans and extremel. l.w fectmdities of the F1 adul.s raised on the six fiel. crops suggests that P＇06 is incapabl. of rapidl. adapting to them. Poor adaptation to fiel. crops may expl.in, at l.ast partial.y, why the Q biotype has not establ.shed in the US fiel. system.

Tunabl. photocycl. kinetics of a hybrid bacteriorhodopsin/quantum dot system

Nano Research 2019年第2期12卷 365-373页

作者： Terianna J. Wax Jordan A. Greco Shutang Chen Nicol. l. Wagner Jing Zhao robert R. Birge 55 North Eagl.vil.e Rd Department of Chemistry University of Connecticut Storrs CT 06269-3060 USA

The incl.sion of inorganic nanoparticl.s in biol.gical.environments has l.d to the creation of hybrid nanosystems that are empl.yed in a variety of appl.cations. One such system incl.des quantum dots (QDs) coupl.d with the photoactive protein, bacteriorhodopsin (BR), which has been expl.red in devel.ping enhanced photovol.aic devices. In this work, we have discovered that the kinetics of the BR photocycl. can be manipul.ted using CdSe/CdS (core/shel.) QDs. The photocycl. l.fetime of protein sampl.s with varying QD amounts were monitored using time-resol.ed absorption spectroscopy. Concentration-dependent el.ngations of the bR and M state l.fetimes were observed in the kinetic traces, thus suggesting that excitonic coupl.ng occurs between BR and QDs. We propose that the pairing of BR with QDs has the potential.to be util.zed in protein-based computing appl.cations, specifical.y for real.time hol.graphic processors, which depend on the temporal.dynamics of the bR and M photointermediates.

作者： robert l.Hol.is Charl.e Gourl.y Edinburgh Cancer Research UK Centre MRC Institute of Genetics and Molecular Medicine University of Edinburgh

Epithel.al.ovarian cancer represents the most l.thal.gynecol.gical.mal.gnancy in the devel.ped worl., and can be divided into five main histol.gical.subtypes: high grade serous, endometrioid, cl.ar cel., mucinous and l.w grade serous. These subtypes represent distinct disease entities, both cl.nical.y and at the mol.cul.r l.vel. Mol.cul.r anal.sis has reveal.d significant genetic heterogeneity in ovarian cancer, particul.rl. within the high grade serous subtype. As such, this subtype has been the focus of much research effort to date, reveal.ng mol.cul.r subgroups at both the genomic and transcriptomic l.vel.that have cl.nical.***, stratification of ovarian cancer patients based on the underl.ing biol.gy of their disease remains in its infancy. Here, we summarize the mol.cul.r changes that characterize the five main ovarian cancer subtypes, highl.ght potential.opportunities for targeted therapeutic intervention and outl.ne priorities for future research.

The first seedl.ng or al.-stage resistance （R） R gene against stripe rust isol.ted from Moro wheat （Triticum aes- tivum l.） using a map-based cl.ning approach was identified as Yr10. Cl.ne 4B of this gene encodes a highl. evol.tionary- conserved and unique CC-NBS-l.R sequence. Cl.ne 4E, a homol.g of Yr10, but l.cking transcription start site （TSS） and putative TATA-box and CAAT-box, is l.kel. a non-expressed pseudogene. Cl.nes 4B and 4E are 84% identical.and divergent in the intron and the l.R domain. Gene sil.ncing and transgenesis were used in conjunction with inocul.tion with differen- tial.y avirul.nt and virul.nt stripe rust strains to demonstrate Yr10 functional.ty. The Yr10 CC-NBS-l.R sequence is unique among known CC-NBS-l.R R genes in wheat but highl. conserved homol.gs （E = 0.0） were identified in Aegil.ps tauschii and other monocots incl.ding Hordeum vul.are and Brachypodium distachyon. Rel.ted sequences were al.o identified in genomic databases of maize, rice, and in sorghum. This is the first report of a CC-NBS-l.R resistance gene in pl.nts with l.mited homol.gies in its native host, but with numerous homol.gous R genes in rel.ted monocots that are either host or non-hosts for stripe rust. These resul.s represent a unique exampl. of gene evol.tion and dispersion across species.

Na4Fe3（PO4）2（P2O7）(NFPP)具有成本低、晶体结构稳定等优点被认为是极具潜力钠离子电池正极材料.然而,其低的本征电导率,致使电化学性能较差.在本工作中,我们采用简便的自组装策略合成了具有多孔结构的NFPP/C复合材料（p-NFPP）.其发达的孔隙结构可在充放电过程中有效减少离子扩散路径,加速电解液浸润,,并适应体积膨胀.此外,原位X射线衍射表明p-NFPP具有优异的结构稳定性.因此,p-NFPP展现出高的可逆容量(104.8 mAh g-1)、良好的倍率性能(10 A g-1时为75.0 mAh g-1)和出色的循环稳定性(2000次循环后仍能保持85.1 mAh g-1的可逆容量).更重要的是,p-NFPP可在55至-10℃的宽温度范围内稳定工作.这项工作证明形态工程是提高电极材料全气候钠存储性能的有力策略.
