Insuffic.ent future liver remnant (FLR) is an important fac.or that prec.udes patient from upfront major liver resec.ion as it predisposes to post-hepatec.omy.liver failure and mortality. As suc., augmentation of FLR by.portal vein embolization (PVE) was the c.nventional approac. to improve the safety.profile of major hepatec.omy. In rec.nt y.ars, assoc.ating liver partition and portal vein ligation for staged hepatec.omy.(ALPPS) has been popularized as an alternative approac. for FLR augmentation (1,2). However, the initial inc.ption of the ALPPS proc.dure was met by.c.itic.sm for its high inc.denc. of proc.dure-related morbidity. suc. as bile leakage and sepsis (3). In light of this issue, an international registry.was set up for c.llec.ion of c.ses and experienc. around the world and soon after that, the first International Expert Meeting was held in Hamburg in 2015 that led to the public.tion of eight rec.mmendations on terminology.of the proc.dures, indic.tions and tec.niques for ALPPS (4). Two y.ars later, a pre-c.ngress meeting was held during the EHPBA (European Hepatopanc.eatobiliary.Assoc.ation) 12th Annual c.ngress in Mainz, Germany.to c.lebrate the 10th Anniversary.of ALPPS (5) sinc. the first c.se was performed by.Prof. Hans Sc.litt a dec.de ago (1). During this meeting, ten different aspec.s on ALPPS were c.vered inc.uding surgic.l anatomy. underly.ng mechanisms, perioperative assessment of liver func.ion, tec.nic.l approac., indic.tions and its effec.iveness in c.mparison to two-stage hepatec.omy.

运用微分几何中的切触原理,研究了在多轴数控机床中铣刀铣削圆与零件曲面的切触条件和局部坐标系下的局部三阶切触条件,并用截形对铣刀铣削圆与曲面的贴近程度进行了分析。相对于现有文献的论述,本文深入到曲面三阶参数而不仅是二阶参数曲率,既适合初等解析曲面又适合计算几何的拟合曲面,计算过程确切(曲率的导数很难求),求解方便(只要解一阶非线性方程)。

The aim of this study.was to perform c.mputational fluid dy.amic. (c.D) simulations on the airflows at the Hong Kong International Airport (HKIA). In partic.lar, the effec.s of hangar buildings and terrain were studied to explore the effec.s of turbulenc. on fly.ng airc.aft, espec.ally.during landing. The c.D simulation showed that signific.nt differenc.s in wind speeds may.oc.ur between the north and the south runway. on the western part of the HKIA under ty.hoon c.nditions with a strong north to northwesterly.wind. Simulation also showed that the hanger buildings between the two runway. on the western side and the nearby.terrain c.uld be c.using the observed differenc. in the wind speeds. The results also indic.ted that these obstac.es c.uld c.use signific.nt wind speed variations at the western end of the south runway. This may.affec. the operation of landing airc.aft. The c.D results for a ty.ic.l ty.hoon c.se were analy.ed and found to matc. the wind data rec.rded by.an airc.aft landing that day.

Two ty.es of resonanc. absorbers, i.e., Salis- bury.sc.eens and Jaumann absorbers are sy.tematic.lly.investigated in solar radiation absorption. Salisbury.sc.een is a metal-dielec.ric.metal struc.ure whic. overc.mes the drawbac. of bulky.thic.ness for solar spec.rum. Suc. struc.ures have a good spec.ral selec.ive absorption property. whic. is also insensitive to inc.dent angles and polarizations. To further broaden absorption bandwidth, more metal and dielec.ric.films are taken in the struc.ure to form Jaumann absorbers. To design optimized struc.ural parameters, the admittanc. matc.ing equations have been derived in this paper to give good initial struc.ures, whic. are valuable for the following optimization. Moreover, the analy.is of admittanc. loc. has been c.nduc.ed to direc.ly.show the effec. of eac. lay.r on the spec.ral absorptivity. and then the effec. of thin films is well understood. Sinc. the fabric.tion of these lay.red absorbers is muc. easier than that of other nanostruc.ured absorbers, Salisbury.sc.een and Jaumann absorbers have a great potential in large-area applic.tions.

c.mpany.bankruptc.es c.st billions of dollars in losses to banks eac. y.ar. Thus c.edit risk predic.ion is a c.itic.l part of a bank＇s loan approval dec.sion proc.ss. Traditional financ.al models for c.edit risk predic.ion are no longer adequate for desc.ibing today.s c.mplex relationship between the financ.al health and potential bankruptc. of a c.mpany. In this work, a multiple c.assifier sy.tem （embedded in a multiple intelligent agent sy.tem） is proposed to predic. the financ.al health of a c.mpany. In our model, eac. individual agent （c.assifier） makes a predic.ion on the likelihood of c.edit risk based on only.partial information of the c.mpany. Eac. of the agents is an expert, but has limited knowledge （represented by.features） about the c.mpany. The dec.sions of all agents are c.mbined together to form a final c.edit risk predic.ion. Experiments show that our model out-performs other existing methods using the benc.marking c.mpustat Americ.n c.rporations dataset.

This artic.e provides a review of c.rrent researc. ac.ivities that c.nc.ntrate on Ti3Sic.. We begin with an overview of the c.y.tal and elec.ronic.struc.ures, whic. are the basis to understand this material. Followings are the sy.thetic.strategies that have been exploited to ac.ieve, and the formation mechanism of Ti3Sic.. Then we devote muc. attentions to the mechanic.l properties and oxidation/hot c.rrosion behaviors of Ti3Sic. as well as some advanc.s ac.ieved rec.ntly. At the end of this paper, we elaborate on some new disc.veries in the Ti3Sic. sy.tem, and also give a brief disc.ssion foc.sed on the ＂mic.ostruc.ure -property. relationship.
