大脑皮层广泛区域的神经成像对于理解神经环路以及调节脑功能至关重要。目前,仍缺乏具有临床应用潜力的高强度、可穿透的光学颅窗工具。北京大学许胜勇教授团队,利用钛(Ti)的高强度特性,以及聚二甲基硅氧烷(PdMS)的高清晰度和可穿透特性,设计一种新型的钛网透明颅窗(Ti-PdMS颅窗)。该人工颅窗生物兼容性好,可长期进行活体动物脑部注射及双光子成像。主要结果:(1)依托于计算机辅助设计、3d打印技术制备的Ti网框架,可定制为任意形状和尺寸,以匹配不同动物的颅骨形态(如小鼠、大鼠和兔子等)。Ti网框架具有高强度特性,其机械强度与人类头骨相似。(2)PdMS薄膜具有高清晰度的特性。在可见光区域,PdMS薄膜的透光率和折射率均优于#1盖玻片。双光子成像结果显示,透过PdMS和盖玻片观察小鼠脑切片,小胶质细胞和神经元的荧光强度无明显差异。(3)PdMS类似于橡胶,弹性好,具有可穿透性和“自密封”特性。透过PdMS薄膜进行注射,可防止液体外漏。

发酵是啤酒酿造过程中最为耗时的工序。一直以来,专家都在不断研究尝试改进工艺技术,啤酒连续老熟法的问世,为啤酒生产商提供了理想的解决方案。传统的啤酒发酵方法,一般需时2～4周,而这种新式的连续老熟法生产工艺,则能够在短短的2小时内,使啤酒达到强化的老熟。其特点在于以小型后发酵容器替代了大型发酵罐,并且把酵母固定在一个烧结玻璃载体上,大大减少投资与经付战本。生产工艺采用连续老熟法生产啤酒,从酿造至主发酵的生产过程,基本上与传统的生产:工艺相同。其主要分别在于后发酵阶段是采用载体固定的酵母进行,有助于缩短所需的工艺时间,其工岂流程见图一。

The N* physics program at Jefferson Lab

Chinese Physics C 2009年第12期33卷 1043-1050页

作者： Volker d. Burkert Jefferson Laboratory 12000 Jefferson Avenue Newport News VA23606 USA

Recent measurements of nucleon resonance transition form factors with CLAS at Jefferson Lab are discussed. The new data confirm the assertion of the symmetric constituent quark model of the Roper as the first radial excitation of the nucleon. The data on high Q2 nπ＋ production better constrain the branching ratios liNK and [3nn. For the first time, the longitudinal transition amplitude to the S11（1535） was extracted from the nπ＋ data. Also, new results on the transition amplitudes for the d13（1520） resonance are presented showing a rapid transition from helicity 3/2 dominance seen at the real photon point to helicty 1/2 dominance at higher Q2. I also discuss the status of the search for new excited nucleon states.

该研究将位移不连续方法引入三维空间中对边界元数值方法进行改进,旨在有效地减少计算过程中三维空间单元数.该方法通过对裂缝表面进行基础单元划分来表征弹性介质的非连续特征,并有效地降低了计算规模.此外,该文还给出了一个基于双层位势的新基本解.与此同时,可认为该方法能有效地模拟水力裂缝扩展及其与天然断层之间的相互作用效应.
