摘要： Natural foods,such as whole pulses,are recommended in the dietary guidelines of the US and China.The plant cell wall structure in whole pulses has important implications for the nutritional functionalities of starch.In this study,garbanzo bean cells with varying degrees of cell wall integrity were subjected to dry heat treatment(DHT)and used to elucidate the food structure-starch digestion properties of pulse food.The morphological features suggested that all cell samples do not exhibit remarkable changes after being subjected to DHT.Molecular rearrangement and the crystallite disruption of starch granules entrapped in cells occurred during DHT as assessed by the crystal structure and thermal properties.DHT decreased the inhibitory effects of enzymes of both the soluble and insoluble components,but the digestion rate and extent of slightly and highly damaged cell samples did not exhibit significant differences compared with their native counterparts.We concluded that the starch digestion of pulse cotyledon cells is primarily determined by the intactness of the cellular structure.This study reveals the role of food structure on the ability to retain the desirable nutritional properties of starch after subjection to physical modification.

摘要： Wang Shuhe(c.210‒285),also known as Wang Xi or Wang Gaoping,was from Gaoping,present Shanxi Province,or Zoucheng City,Shandong Province.He was one of the celebrated medical scientists of the Wei and Jin dynasties(220e420)and he once served as the minister of imperial physicians.He is the author of The Pulse Classic(Mai Jing),the extant first monograph on pulse in China.Wang was born into a family of nobility.With placid temper he was eager to learn since childhood.As a young boy he had extensive knowledge and studied the various schools of thoughts and their exponents.Then to avoid chaos of war his family moved to Jingzhou City,Hubei Province,where he met Wei Xun,a disciple of Zhang Zhongjing(150e219).

摘要： Pulse-Coding调制解调技术所谓隔离器,类似于在一颗芯片左右两侧的微距离上实现无线射频收发系统,在这样一个收发系统里面,其实包括发射机和接收机以及隔离介质三部分。目前主流架构主要包括Pulse调制架构和00K调制架构。Pulse架构和00K调制架构的优点是低功耗、低传输延迟、高传输速率,缺点则是在有干扰信号的时候容易丢码或增加码造成传输出错,所以CMTI的能力比较差。

摘要： Experiments at the GARPUN KrF laser facility and 2D simulations using the NUTCY code were performed to study the irradiation of metal and polymethyl methacrylate(PMMA)targets by 100 nsUVpulses at intensities up to 5×10^(12)Wcm^(−2).In both targets,a deep crater of length 1mm was produced owing to the 2D geometry of the supersonic propagation of the ablation front in condensed matter that was pushed sideways by a conical shock wave.Small-scale filamentation of the laser beam caused by thermal self-focusing of radiation in the crater-confined plasma was evidenced by the presence of a microcrater relief on the bottom of the main crater.In translucent PMMA,with a penetration depth forUVlight of several hundred micrometers,a long narrow channel of length 1mmand diameter 30μmwas observed emerging from the crater vertex.Similar channels with a length-to-diameter aspect ratio of∼1000 were produced by a repeated-pulse KrF laser in PMMA and fused silica glass at an intensity of∼10^(9)Wcm^(−2).This channel formation is attributed to the effects of radiation self-focusing in the plasma and Kerr self-focusing in a partially transparent target material after shallow-angle reflection by the crater wall.Experimental modeling of the initial stage of inertial confinement fusion-scale direct-drive KrF laser interaction with subcritical coronal plasmas from spherical and cone-type targets using craterconfined plasmas seems to be feasible with increased laser intensity above 10^(14) W cm^(−2).

摘要： Spintronics, which use the spin of electrons rather than their direct motion to carry information, has emerged as one of the leading alternatives to traditional electronics, promising faster information processing and lower energy consumption. Efficient spin injection into semiconductor is a crucial first step to realize useful spintronic devices, which remains an elusive challenge up to now. Recently, a joint group from Nanyang Technological University, the National University of Singapore, and the Agency for Science, Technology and Research (A*STAR) has achieved a breakthrough in the speed and efficiency of spin injection into semiconductor.

摘要： The crystallization characteristics of a ubiquitous T-shaped phase change memory(PCM) cell, under SET current pulse and very small disturb current pulse, have been investigated by finite element modelling. As analyzed in this paper, the crystallization region under SET current pulse presents first on the corner of the bottom electron contact(BEC) and then promptly forms a filament shunting down the amorphous phase to achieve the low-resistance state, whereas the tiny disturb current pulse accelerates crystallization at the axis of symmetry in the phase change material. According to the different crystallization paths, a new structure of phase change material layer is proposed to improve the data retention for PCM without impeding SET operation.This structure only requires one or two additional process steps to dope nitrogen element in the center region of phase change material layer to increase the crystallization temperature in this confined region. The electrical-thermal characteristics of PCM cells with incremental doped radius have been analyzed and the best performance is presented when the doped radius is equal to the radius of the BEC.

摘要： In this paper,narrow-pulse power discharge is used to study the synergistic control of mercury and dioxins,in which 1,2,4-trichlorobenzene(TCB)was used as a dioxin analog,by using a selfdesigned experimental system.The competitive effects of NO,SO2 and HC1 on the TCB removal by non-thermal plasma are discussed.The influence of acid gas on TCB degradation is reflected in the competitive effect.NO has the greatest influence on TCB degradation efficiency.The oxidation efficiency of Hg°decreased by about 10%in all three acidic gas atmospheres,and the effect of each gas component on Hg()oxidation is complex.In the flue gas atmosphere of'acid gas+Hg°+TCB',the mechanism of the synergistic control of Hg°and TCB by the nonthermal plasma is different,which has competition and promotion relationship between each other.The contribution of various flue gas components to the results was complicated,but the overall experimental results show that the synergistic control effect of the system can continue to improve.According to the generated product backstepping,-OH plays an important role in the synergistic control of the degradation of Hg°and TCB.Through this study,we hope to provide basic research data for the collaborative control of flue gas in the incineration industry.
