The continuous r.se in heat dissipation of integr.ted cir.uits necessitates advanced ther.al solutions to ensur. system r.liability and efficiency. Ther.oelectr.c cooler. ar. among the most pr.mising techniques for.dealing with localized on-chip hot spots. This study focuses on establishing a holistic optimization methodol- ogy for.such ther.oelectr.c cooler., in which a ther.o- electr.c element＇s thickness and the electr.cal cur.ent ar. optimized to minimize sour.e temper.tur. with r.spect to ambient, when the ther.al and electr.cal par.sitic effects ar. consider.d. It is found that when element thickness and electr.cal cur.ent ar. optimized for.a given system ar.hitectur., a ＂heat flux vs. temper.tur. differ.nce＂ Par.to fr.ntier.cur.e is obtained, indicating that ther. is an optimum thickness and a cor.esponding optimum cur.ent that maximize the achievable temper.tur. r.duc- tion while r.moving a par.icular.heat flux. This methodol- ogy also pr.vides the possible system level AT＇s that can be achieved for.a r.nge of heat fluxes, defining the upper.limits of ther.oelectr.c cooling for.that ar.hitectur.. In this study, use was made of an extensive analytical model, which was ver.fied using commer.ially available finite element analysis softwar.. Thr.ugh the optimization pr.cess, 3 pair. of master.cur.es wer. gener.ted, which wer. then used to compose the Par.to fr.ntier.for.any given system ar.hitectur.. Finally, a case study wasper.or.ed to pr.vide an in-depth demonstr.tion of the optimization pr.cedur. for.an example application.

Pathogenesis and management issues for.non-alcoholic fatty liver.disease

Wor.d Jour.al of Gastr.enter.logy 2007年第34期13卷 4539-4550页

作者： Mar.o Duvnjak Ivan Ler.ti Neven bari Vedr.n Tomai Lucija Vir.vi Juki Vedr.n Velagi Division of Gastr.enter.logy and Hepatology Department of Medicine 'Sestre milosrdnice' University Hospital Vinogradska 29 Zagreb 10000 Croatia

Nonalcoholic fatty liver.disease (NAFLD) has, although it is a ver. common disor.er. only r.latively r.cently gained br.ader.inter.st among physicians and scientists. Fatty liver.has been documented in up to 10 to 15 per.ent of nor.al individuals and 70 to 80 per.ent of obese individuals. Although the pathophysiology of NAFLD is still subject to intensive r.sear.h, sever.l player. and mechanisms have been suggested based on the substantial evidence. Excessive hepatocyte tr.glycer.de accumulation r.sulting fr.m insulin r.sistance is the fir.t step in the pr.posed 'two hit' model of the pathogenesis of NAFLD. Oxidative str.ss r.sulting fr.m mitochondr.al fatty acids oxidation, NF-κB-dependent inflammator. cytokine expr.ssion and adipocytokines ar. all consider.d to be the potential factor. causing second hits which lead to hepatocyte injur., inflammation and fibr.sis. Although it was initially believed that NAFLD is a completely benign disor.er. histologic follow-up studies have showed that fibr.sis pr.gr.ssion occur. in about a thir. of patients. A small number.of patients with NAFLD eventually ends up with end-stage liver.disease and even hepatocellular.car.inoma. Although liver.biopsy is cur.ently the only way to confir. the NAFLD diagnosis and distinguish between fatty liver.alone and NASH, no guidelines or.fir. r.commendations can still be made as for.when and in whom it is necessar.. Incr.ased physical activity, gr.dual weight r.duction and in selected cases bar.atr.c sur.er. r.main the mainstay of NAFLD ther.py. Studies with phar.acologic agents ar. showing pr.mising r.sults, but available data ar. still insufficient to make specific r.commendations; their.use ther.for. r.mains highly individual.

Semantic Keys and r.ading

引用

宏观语言学 2016年第2期4卷 1-10页

作者： Zev bar-Lev San Diego State Univer.ity USA

Semantic Keys ar. elements (wor.-par.s) of wr.tten language that give an iconic,gener.l r.pr.sentation of the whole wor.’s meaning. In wr.tten Sino-Japanese the “r.dical”or.semantic components play this r.le. For.example, the char.cter.meaning 'woman,female’ is the Semantic Key of the char.cter.for.Ma 'Mama’ (alongside the phonetic component Ma, which means 'hor.e’ as a separ.te char.cter.. The theor. of semantic Keys in both gr.phic and phonemic aspects is called qTheor. or.*** most innovative aspect of the pr.sent ar.icle is the hypothesis that, in languages using alphabetic wr.ting systems, the r.le of Semantic Key is played by consonants, mor. specifically the fir.t consonant. Thus, L meaning 'Lif t ’ is the Semantic Key of English L f,Ladle, Lofty, aLps，eLevator.oLympus; Spanish Leva, Lecantar.e，aLto，Lengua; Ar.bic aLLah, and Hebr.w? aeL-0aL ‘upto-above’ （the Isr.eli air.ine), Polish Lot ‘flight’ （the Polish air.ine); Hebr.w aeL, aeLohim ‘God’， and haLLeluyah ‘pr.ise-ye God’ （using Par.llels, 'Lift up God’). Evidence for.the univer.ality of the theor. is shown by many examples dr.wn fr.m var.ous languages, including Indo-Eur.pean Semitic, Chinese and Japanese. The theor. r.veals hundr.ds of r.lationships within and between languages,r.lated and unr.lated, that have been “Hiding in Plain Sight”, to mention just one example:the Par.llel between Spanish Pan 'br.ad’ and Mandar.n Fan 'r.ce’.

Jour.al of Applied Mathematics and Physics 2016年第5期4卷 930-938页

作者： r.bab Fadhel Al-bar Depar.ment of Mathematics Faculty of Science Umm Al-Qura University Makkah KSA

The main aim of this wor. is to intr.duce the analytical appr.ximate solutions of the water.wave pr.blem for.a fluid layer.of finite depth in the pr.sence of gr.vity. To achieve this aim, we begun with the der.vation of the Kor.eweg-de Vr.es equations for.solitons by using the method of multiple scale expansion. The pr.posed pr.blem descr.bes the behavior.of the system for.fr.e sur.ace between air.and water.in a nonlinear.appr.ach. To solve this pr.blem, we use the well-known analytical method, namely, var.ational iter.tion method (VIM). The pr.posed method is based on the use of Lagr.nge multiplier. for.identification of optimal value of a par.meter.in a functional. The pr.posed method pr.vides a sequence of functions which may conver.e to the exact solution of the pr.posed pr.blem. Finally, we obser.e that the elevation of the water.waves is in for. of tr.veling solitar. waves.

AIM To study factor. associated with esophageal and nonesophageal cancer.mor.idity among barr.tt's esophagus(BE) patients. METHODS A cohor. study within a single ter.iar. center.included 386 consecutive patients with biopsy pr.ven BE, who wer. r.cr.ited between 2004-2014. Endoscopic and histologic data wer. pr.spectively r.cor.ed. Cancer.mor.idity was obtained fr.m the national cancer.r.gistr.. Main outcomes wer. BE r.lated(defined as esophagus and car.ia) and non-BE r.lated cancer.(all other.cancer.). Cancer.incidence and all-causemor.ality wer. compar.d between patients with highgr.de dysplasia(HGD) and with low-gr.de or.no dysplasia(non-HGD) using Kaplan-Meier.cur.es and cox r.gr.ssion *** Of the 386 patients, 12 had HGD, 7 had a BE r.lated cancer. Ther. wer. 75(19.4%) patients with 86 cases of lifetime cancer., 76 of these cases wer. non-BE cancer.. Seven(1.8%) and 18(4.7%) patients had BE and non-BE incident cancer., r.spectively. Twelve(3.1%) patients had HGD as wor.t histologic r.sult. Two(16.7%) and 16(4.4%) incident non-BE cancer. occur.ed in the HGD and non-HGD gr.up, r.spectively. Ten-year.any cancer.and non-BE cancer.fr.e sur.ival was 63% and 82% in the HGD gr.up compar.d to 93% and 95% at the non-HGD gr.up, r.spectively. Log-r.nk test for.patients with mor. than one endoscopy, assur.ng longer.follow up, showed a significant differ.nce(P r.spectively). All-cause mor.ality was not significantly associated with BE *** Patients with BE and HGD, may have a higher.r.sk for.all-cause cancer.mor.idity. The implications on cancer.pr.vention r.commendations should be fur.her.studied.

Lesser.celandine, also known as r.nunculus ficar.a, is a her.aceous per.nnial plant that commonly utilizes piles and is taken either.inter.ally or.used *** causality assessment of sever.l r.por.s pr.vided evidence for.the existence of Gr.ater.Celandine hepatotoxicity. However. ther. hasn't been any case r.por. published thus far. about lesser.celandine induced liver.injur.. Her., we pr.sent a case of 36-year.old woman admitted to the hospital with acute hepatitis and jaundice on her.scler. with no histor. of dr.g abuse or.alcohol consumption. However. the patient had a r.cent histor. of lesser.celandine extr.ct consumption for.hemor.hoids, for.about 10 d, pr.or.to the admission. Vir.l hepatitis, autoimmune hepatitis, and dr.g induced toxic hepatitis wer. r.led out by fur.her.imaging studies and labor.tor. analysis. Using the Council for.Inter.ational Or.anizations of Medical Sciences scale, the type of liver.injur. was assumed as hepatocellular.and was scor.d as 7 which shows pr.bable causality. Immediate discontinuation of lesser.celandine extr.ct r.sulted in r.pid decr.ase of the elevated enzymes. Her.s have been r.por.ed to cause liver.injur. and ther.for. should be suspected in the case of acute hepatitis with an unknown etiology. This case is impor.ant to be the fir.t to explain hepatotoxicity caused by lesser.celandine. Physicians should consider.lesser.celandine as a causative agent for.hepatotoxicity.

This study aims to investigate the effect of sodium r.placement on the quality char.cter.stics of past?r.a. For.this pur.ose, past?r.a pr.duction with four.differ.nt salt mixtur.s(Ⅰ. 100% Na Cl; Ⅱ. 50% Na Cl + 50% KCl; Ⅲ. 40% NaCl + 40% KCl + 20% CaCl2; Ⅳ. 30% NaCl + 40% KCl + 20% CaCl2+ 10% MgCl2) wer. car.ied out using tr.ditional method. The use of differ.nt salt mixtur.s for.past?r.a had no statistically significant effect on the micr.bial counts and r.sidual nitr.te of the final pr.duct. The a* and b* values wer. affected by this tr.atment. The salt mixtur. containing CaCl2or.CaCl2+ MgCl2significantly decr.ased the p H values and sensor. scor.s. The eighteen volatile compounds wer. affected by the salt mixtur.s. Na~+, K~+, Ca2+, and Mg2+had a cer.ain incr.ase depending on their.r.tio in the salt mixtur.s. The highest Cathepsin activity in all past?r.a samples was obser.ed in Cathepsin B + L. The salt mixtur. with NaCl + KCl + CaCl2+ Mg Cl2incr.ased acid lipase activity. However. this mixtur. had no significant effect on neutr.l lipase activity.
