泥盆纪是地球历史之中碳质页岩的全球性沉积作用一个特别显著的幕。在黔桂地区深水沉积主导的台间盆地相之中,从早泥盆世的埃姆斯期到晚泥盆世的弗拉期,集中发育一套总厚度超过600 m的富有机质竹节石页岩,以下特征表明这些富有机质的竹节石页岩将成为重要的潜在性页岩气勘探目的层:(1)页岩的总有机碳含量(TOC)值多为2%～4%,可以高达5%～6%;(2)从早泥盆世的埃姆斯期至中泥盆世,有机碳多集中富集在三级海平面相对上升期沉积的、而且单层厚度常常超过百米的富有机质竹节石页岩主导的缺氧盆地相沉积之中,相对应的三级海平面下降期则为亏损有机碳的陆棚相沉积;(3)在晚泥盆世弗拉期硅质岩主导的榴江组之中,有机碳多富集在三级海平面下降期的、单层厚度为30～40 m的缺氧盆地相富有机质竹节石页岩之中,所对应的三级海平面上升期则为硅质岩主导的而且亏损有机碳的远洋盆地相沉积。暂时归为缺氧盆地相的富有机质竹节石页岩中的有机质堆积作用,主要受到以下三个因素之间的复杂的非线性相互作用所控制:生产率、保存作用和沉积作用速率;更为特别而且重要的是,基于高密度保存的竹节石化石(含量可以超过30%),研究区的泥盆纪富有机质竹节石页岩,除了这三个因素之外,浮游动物的“生物碳泵(the biological carbon pump)”作用过程,将是这些竹节石页岩富集有机质的另外一个重要机理。

Inhibins play important roles in the reproductive system. To evaluate whether inhibin α (1-32) fusion protein plays a role in cervical cancer growth, the plasmid pVAX-inhα was constructed and its effect on proliferation and apoptosis of the human cervical cancer cell line (Hela) was checked by flow cytometry and real-time PCR. The expression and localization of inhibin α protein were detected by RT-PCR and confocal mi- croscopy which showed that inhibin α protein was expressed and localized in the nucleus of Hela cells. Over ex- pression of inhibin α gene significantly induced cell apoptosis and ceased S phase of cell cycle. Furthermore, cell proliferation was significantly suppressed 96 h post-transfection and mRNA level of anti-apoptosis genes (Bcl-2, NFκB) were decreased but pro-apoptosis genes (Bax, wild type p53) and inhibin co receptor (TGFβR3) were increased, indicating that inhibin, through its co-receptor, might activate apoptotic and cell growth cascades which regulate proliferation and apoptosis in Hela cells. These results suggest that inhibin α (1-32) fusion pro- tein, located in the cell nucleus, can regulate Hela cells growth and apoptosis by induction of apoptotic pathways such as NFκB, Bcl-2 and p53 families. These findings may have a significant impact on future research regarding cervical cancer cell lines.

Over last few years, web services, Java 2 and XML have provided the cheaper means for trading partners to make use of EDI. It is now possible to share data with less reliance on expensive dedicated EDI networks. The second comes the realization that Product Definition can be reused by virtually all business processes downstream. This has made collaborative product development a practical reality. These technologies have enabled effective implementation of Product Lifecycle Management (PLM) Solutions. This paper presents a literature review about PLM solutions, looking at its definitions, through to its need and scope of applications. It also presents the most generally envisaged architecture, explaining as to how it may be looked at and what it is expected to deliver. At the end it examines the market trend and revenue growth over recent years including future trends for the most prominent vendors pitched in the field of PLM solutions.

纤维状水不溶性材料—纤维素被认为是地球上最常见的生物衍生聚合物,是最著名和最欢迎的可再生和可重复使用的原材料。纳米纤维素是至少在一个维度上小于100 nm的纤维素纤维的术语。纳米纤维素原纤维天然较小且亲水,因为它们的表面有很多羟基。它们有90%是结晶的,直径在10到100 nm之间。本文介绍了纳米纤维素的工艺、特性和用途,重点介绍了食品包装。广泛的行业可能会受益于纳米纤维素的使用,它可以应对多项环境挑战。作为用于涂层、自立薄膜和复合材料制造的可生物降解填料,它具有独特而有趣的特性。很少对用于包装已涂有纳米纤维素的食品的复合材料进行评估。对于由生物聚合物和合成聚合物制成的复合材料的机械和阻隔性能,纳米纤维素增强材料已显示出希望。在这篇文章中,我们全面概述了纳米纤维素制造的当前发展及其作为填料在创建用于食品包装的纳米复合材料中的用途。

Ensuring the correctness of answers to substring queries has not been a concern for consumers working within the traditional confines of their own organisational infrastructure. This is due to the fact that organisations generally trust their handling of their own data hosted on their own servers and networks. With cloud computing however, where both data and processing are delegated to unknown servers, guarantees of the correctness of queries need to be available. The verification of the results of substring searches has not been given much focus to date within the wider scope of data and query, verification. We present a verification scheme for existential substring searc, hes on text files, which is the first of its kind to satisfy the desired properties of authenticity, completeness, and freshness. The scheme is based on suffix arrays, Merkle hash trees and cryptographic hashes to provide strong guarantees of correctness for the consumer, even in fully untrusted environments. We provide a description of our scheme, along with the results of experiments conducted on a fully-working prototype.

本论文的重点是利用控制理论和工程方法实现量子门。由于量子门的实现对于实现量子计算机的实现非常重要,控制量子门系统的量子系统方法对量子计算机的实现非常重要。本文基于Lyapunov方法研究了—个量子比特量子门的实现,并采用最优控制方法实现了两个量子比特量子门。为了实现—个量子位量子门,我们采用了基于Lyapunov的方法,这是因为—个量子位系统是最简单的量子系统,—个量子位系统的演化要么位于布洛赫球体上要么在其内部,这非常简单,几何结构,这类系统的演化类似于球体上或球体内的经典旋转。多量子比特量子系统不同于—个量子比特系统,因为我们不能将它们的演化看作是球上的演化,这是由于相互作用的结果导致多量子比特量子系统的纠缠,这是我们的主要原因没有将我们的Lyapunov方法扩展到多量子位系统。为了实现多量子比特量子系统的相干控制,最广泛采用的方法是最优量子控制。基于最优控制的策略具有的优点是,在实现中也可以考虑诸如控制频带限制和幅度限制的实验性约束。因此,对于两个量子位量子门合成,我们应用了最佳控制方法如Krotov方法,GRAPE,CRAB以及CRAB和GRAPE的组合。在本论文中,对于具有Ising型漂移的封闭两个量子比特量子系统的可控非门的制备,所有这些方法都进行了研究和比较。本文还表明,基于梯度的量子门设计优化控制方法比非梯度方法有更好的表现。
