Soil salinization is a land.d.grad.tion p.ocess that lead. to red.ced.agricultural yield.. This stud. investigated.the method.that can best p.ed.ct electrical cond.ctivity (EC) in d.y soils using ind.vid.al band., a normalized.d.fference salinity ind.x (Nd.I), p.rtial least squares regression (p.SR), and.bagging p.SR. Soil sp.ctral reflectance of d.ied. ground. and.sieved.soil samp.es containing varying amounts of EC was measured.using an ASd.Field.p.c sp.ctrometer in a d.rkroom. p.ed.ctive mod.ls were comp.ted.using a training d.taset. An ind.p.nd.nt valid.tion d.taset was used.to valid.te the mod.ls. The results showed.that good.p.ed.ctions could.be mad. based.on bagging p.SR using first d.rivative reflectance (valid.tion R2 = 0.85), p.SR using untransformed.reflectance (valid.tion R2 = 0.70), Nd.I (valid.tion R2 = 0.65), and.the untransformed.ind.vid.al band.at 2257 nm (valid.tion R2 = 0.60) p.ed.ctive mod.ls. These suggested.the p.tential of map.ing soil salinity using airborne and.or satellite hyp.rsp.ctral d.ta d.ring d.y seasons.

The p.esent p.p.r rep.rts the results of a d.tailed.exp.rimental stud. aimed.at investigating the d.namics of a laminar sep.ration bubble, from the origin of sep.ration up.to the breakd.wn to turbulence of the large scale co- herent structures generated.as a consequence of the Kelvin-Helmholtz instability p.ocess. Measurements have been p.rformed.along a fiat p.ate installed.within a d.uble contoured.test section, d.signed.to p.od.ce an ad.erse p.essure grad.ent typ.cal of Ultra-High-Lift turbine blad. p.ofiles, which ind.ces the formation of a laminar sep.ration bubble at low Reynold. number cond.tion. Measurements have been carried.out by means of comp.e- mentary techniques： hot-wire （HW） anemometry, Laser d.p.ler Velocirnetry （Ld.） and.p.rticle Image Veloci- metry （p.V）. The high accuracy 2-d.mensional Ld. results allow investigating reverse flow magnitud. and.both Reynold. normal and.shear stress d.stributions along the sep.rated.flow region, while the high frequency resp.nse of the HW anemometer allows analyzing the amp.ification p.ocess of flow oscillations ind.ced.by instability mechanisms. p.V results comp.ement the flow field.analysis p.ovid.ng information on the generation and.evolu- tion of the large scale coherent structures shed.as a consequence of the sep.rated.shear layer roll-up. through in- stantaneous velocity vector map.. The simultaneous analysis of the d.ta obtained.by means of the d.fferent meas- uring techniques allows an in d.p.h view of the instability mechanisms involved.in the transition/reattachrnent p.ocesses of the sep.rated.shear layer.

p.rity violation in electron scattering

引用

Frontiers of p.ysics 2016年第1期11卷 39-69页

作者： p. Soud.r K. d. p.schke Syracuse University Syracuse NY 13244 USA

By comp.ring the cross Sections for left- and.right-hand.d.electrons scattered.from various unp.larized.nuclear targets, the small p.rity-violating asymmetry can be measured. These asymmetry d.ta p.obe a wid. variety of imp.rtant top.es, includ.ng searches for new fund.mental interactions and.imp.rtant features of nuclear structure that cannot be stud.ed.with other p.obes. A sp.cial feature of these exp.riments is that the results are interp.eted.with remarkably few theoretical uncertainties, which justifies p.shing the exp.riments to the highest p.ssible p.ecision. To measure the small asymmetries accurately, a number of novel exp.rimental techniques have been d.velop.d.

In this p.p.r, we stud. the effects of heat transfer on the p.ristaltic magneto- hyd.od.namic （MHd. flow of a Bingham fluid.through a p.rous med.um in a channel. Long wavelength ap.roximation （that is, the wavelength of the p.ristaltic wave is large in comp.rison with the rad.us of the channel） and.low Reynold. number are used.to linearize the governing equations. The velocity field.for the mod.l of interest is solved.by Ad.mian d.comp.sition method. The exp.essions for p.essure rise, flow rate and.frictional force are obtained. The effect of magnetic field. d.rcy number, yield.stress, amp.itud. ratio and.the temp.rature on the axial p.essure grad.ent, p.mp.ng charac- teristics and.frictional force are d.scussed.through grap.s.

p.ed.cting treatment resp.nses in ad.anced.p.ostate cancer （p.a） currently centres on p.ostate-sp.cific antigen （p.A） kinetics and.on being able to visualize measurable changes in imaging mod.lities. New molecular markers have emerged.as p.tential d.agnostic and.p.ognostic ind.cators; these were summarized.in p.rt I of this review in the Asian Journal ofAnd.ology. A number of molecular markers are now being used.to enhance p.a imaging and.staging. However, management op.ions for ad.anced.and.hormone-resistant p.a （HRp.） are limited.and.ad.itional therap.utic op.ions are need.d. Molecular markers have been p.op.sed.as p.tential therap.utic targets using gene therap. and.immunomod.lation. Ad.itionally, markers id.ntified.in early p.a and.p.ecursor lesions may offer novel targets for chemop.evention and.vaccine d.velop.ent. This review summarizes the current ad.ances regard.ng the roles of these markers in the management of p.a.

The suction sid. bound.ry layer evolution of a high-lift low-p.essure turbine cascad. has been exp.rimentally in- vestigated.at low and.high free-stream turbulence intensity cond.tions. Measurements have been card.d.out in ord.r to analyze the bound.ry layer transition and.sep.ration p.ocesses at a low Reynold. nttmber, und.r both stead. and.unstead. inflows. Static p.essure d.stributions along the blad. surfaces as well as total p.essure d.stri- butions in a d.wnstream tangential p.ane have been measured.to evaluate the overall aerod.namic efficiency of the blad. for the d.fferent cond.tions. p.rticle. Image Velocimetry has been ad.p.ed.to analyze the time-mean and.time-varying velocity field.. The flow field.has been surveyed.in two orthogonal p.anes （a blad.-to-blad. p.ane and.a wall-p.rallel one）. These measurements allow the id.ntification of the Kelvin-Helmholtz large scale cohe- rent structures shed.as a consequence of the bound.ry layer laminar sep.ration und.r stead. inflow, as well as the investigation of the three-d.mensional effects ind.ced.by the intermittent p.ssage of low and.high sp.ed.streaks. A close insp.ction of the time-mean velocity p.ofiles as well as of the bound.ry layer integral p.rameters help. to characterize the suction sid. bound.ry layer state, thus justifying the influence of free-stream turbulence intensity on the blad. aerod.namic losses measured.und.r stead. and.unstead. inflows.

The p.otop.od.ction of K＋ mesons from the nucleon p.ovid.s imp.rtant constraints on the nucleon excitation sp.ctrum and.at threshold.energies challenges effective field.theories based.on chiral p.rturbation in the strange quark sector. p.eliminary cross-section measurements for γ（p. K＋）A are p.esented.at an unp.eced.nted.beam energy resolution. The d.ta was collected.at the MAMI-C facility in Mainz using the Crystal Ball d.tector. A new method.of K＋ d.tection was used.in which the K＋ is tagged.from its weak d.cay p.od.cts in the d.tector crystals. This technique has ap.lication with other calorimeters at p.esent and.future had.on facilities.

Journal of Zhejiang University-Science A(Ap.lied.p.ysics & Engineering) 2010年第10期11卷 744-755页

作者： H. WANG p. d. WU K. W. NEALE d.p.rtment of Mechanical Engineering McMaster University Hamilton Ontario L8S 4L7 Canada Faculty of Engineering University of Sherbrooke Sherbrooke Quebec J1K 2R1 Canada

The recently d.velop.d.elastic-viscop.astic self-consistent mod.l with various self-consistent schemes was ap.lied.to stud. the effect of basal texture on the mechanical behavior of magnesium alloy AZ31B sheet. The influence of the basal texture was investigated.using various initial textures generated.by artificially tilting the measured.texture of the reference AZ31B sheet around.in a transverse d.rection. The material p.rameters for the various mod.ls were fitted.to exp.rimental uniaxial tension and.comp.ession along the rolling d.rection and.were then used.to stud. the effects of the basal texture on the yield.stress, R value, ultimate stress and.uniform strain und.r uniaxial tension. The effect of the basal texture on sheet metal forming was further assessed.by calculating the limit strain und.r in-p.ane p.ane strain tension. An assessment of the p.ed.ctive cap.bility of p.lycrystal p.asticity mod.ls was mad. based.on comp.risons of p.ed.ctions and.exp.rimental observations. Among the available self-consistent ap.roaches, the Affine self-consistent scheme resulted.in the best overall p.rformance.
