We proposed and demonstrated that PT symmetric metamaterials could be used to achieve enhanced spin Hall effect(SHE)of *** find that when laser mode is excited in PT symmetric system,the enhanced SHE could be obtained in both transmitted and reflected *** addition,as exceptional points(EPs)of PT symmetric system can happen for both p-and s-polarizations,the enhanced SHE of reflected light can function for both horizontally and vertically polarized incident ***,these EPs can lead to unidirectional reflectionlessness,asymmetric SHE with maximum contrast ratio of 48 is obtained by launching light beams near *** work opens up a new path to obtain enhanced transverse displacement for both reflected and transmitted light and enables more opportunities in manipulating photonic SHE.

A novel acrylate inimer, 2-（2-chloroacetyloxy） ethyl acrylate, was prepared by the reaction of 2-hydroxyethyl acrylate with chloroacetyl chloride in the presence of triethylamine. The self-condensing vinyl living radical polymerization of the inimer was studied and the hyperbranched macromolecules containing ester linkages on their backbone were prepared. All the polymerization products were characterized by 1H NMR. The polymerization degree and the branching parameter were calculated based on the 1H NMR spectra. It has been shown that this inimer exhibits a very distinctive polymerization behavior. Similar to step-growth polymerization, the polymerization degree of the products formed increased exponentially during the early stage of the polymerization, and then the increasing rate slowed down. However, the inimer remained present throughout the polymerization consistent with conventional free radical polymerization. Also, if much longer polymerization time was used, the polymerization system would become gel due to the crosslinking reaction derived from radical-radical recombination. As a result of the unequal reactivity of -CH2Cl and >CHCl, an almost linear product was obtained at a molar ratio of bipy to inimer=0.05, while a relatively high ratio of bipy to inimer 1 favored the formation of the branched structure. The macromolecules formed at a high ratio of bipy to inimer 1 exhibited an excellent solubility in organic solvents such as acetone.

Cardiac arrest(CA)is one of the most common causes of death.[1-3]Despite extensive studies on the management of CA,the global survival rate in adults is only approximately 7%,and 30-day survival is even less than 2%in China.[4]Some studies have shown that CA patients of cardiac and non-cardiac origin may differ in underlying diseases,clinical manifestations,and prognosis,which leads to diff erences in terms of the pathophysiological mechanism and treatment measure.[5,6]However,little is known about the risk factors in relation to the prognosis of CA across arrest etiologies.

INTRODUCTIONfulminant hepatic failure(FHF)is a severe disease with devastating consequences;the incidence is high in *** the availability of liver transplantation,the mortality rate was more than 80%[1,2].The advent of liver transplantation revolutionized the outcome of FHF[3,4].However,many patients were unwilling to accept liver transplantation until very late,hence most of them died because of donor shortage and urgency of the disease[5-7],To overcome he problems,we performed orthotopic liver transplantation(OLT)in combination with artificial liver support(ALS) in the treatment of FHF in the past 2 years with satisfactory *** experience was reported below.

低地板有轨电车因在城市中运行,道路工况复杂、小曲线半径较多,轮轨磨耗较为严重。又因轨道基本都使用槽型轨,在一定情况下槽型轨轨槽会与轮背发生接触,同样会发生磨耗。为研究车轮磨耗规律,以国内自主研发的新型70%低地板有轨电车为研究对象,建立其动力学模型,基于Archard磨耗模型及轮轨多点非椭圆接触理论对磨耗演变过程进行模拟,研究不同轮背内侧距下的车轮磨耗问题。结果表明,轮背内侧距对直线和曲线工况磨耗问题的影响是相互矛盾的,在一定范围内轮背内侧距越小对直线工况越有利,而对曲线工况不利。通过对实际运行线路的磨耗情况研究发现,车轮磨损主要发生在曲线行驶中,对车辆在整条线路上的磨耗问题进行优化,综合考虑直线与曲线所占比例,当轮背内侧距为1 376 mm时磨耗问题得到最优,对于使用槽型轨的车辆设计时轮背内侧距应当与车辆悬挂参数相匹配。
