Laboratory tests on the large post-liquefaction deformation of saturated Nanjing fine sand were performed by using a hollow cylinder apparatus. The stress-strain responses and the characteristics of excess pore water pressure after liquefaction were studied. It was found that the relationship between deviatoric stress and axial strain presented a sigmoid curve, and there was a good linearity relationship between normalized pore water pressure and deviatoric stress. On this basis, a constitutive model of stress-strain responses and a dissipation model of excess pore water pressure were established. It was found that the results predicted by the two models were in good agreement with the experimental data. The influence of relative densities and confining pressure on the characteristics of liquefied soil were studied, The results showed the relative densities and initial effective confining pressure all had an important influence on the stress-strain responses of liquefied saturated Nanjing fine sand. However, the dissipation model of excess pore water pressure after liquefaction was only affected by the confining pressure.

With the development of Moore's law, the future trend of devices will inevitably be shrinking and integration to further achieve size reduction. The emergence of new two-dimensional non-layered materials(2DNLMs) not only enriches the 2D material family to meet future development, but also stimulates the global enthusiasm for basic research and application technologies in the 2D field. Van der Waals(vd W) heterostructures, in which two-dimensional layered materials(2DLMs)are physically stacked layer by layer, can also occur between 2DLMs and 2DNLMs hybrid heterostructures, providing an alternative platform for nanoelectronics and optoelectronic applications. Here, we outline the recent developments of2DLMs/2DNLMs hybrid heterostructures, with particular emphasis on major advances in synthetic methods and applications. And the categories and crystal structures of 2DLMs and 2DNLMs are also shown. We highlight some promising applications of the heterostructures in electronics, optoelectronics, and catalysis. Finally, we provide conclusions and future prospects in the 2D materials field.

Objective To review the advances in studies on renal denervation. Data sources References concerning renal denervation and resistant hypertension cited in this review were collected from PubMed published in English and those of renal denervation devices from official websites of device manufacturers up to January 2014. Study selection Articles with keywords ＂renal denervation＂ and ＂resistant hypertension＂ were selected. Results Renal and systemic sympathetic overactivity plays an important role in pathology of hypertension as well as other diseases characterized by sympathetic overactivity. Renal denervation is a new, catheter based procedure to reduce renal and systemic sympathetic overactivity by disruption of renal sympathetic efferent and afferent nerves through radiofrequency or ultrasound energy delivered to the endoluminal surface of both renal arteries. Although several studies have shown the efficacy and safety of renal denervation in the treatment of resistant hypertension and the potential benefit of the procedure in other diseases, Symplicity HTN 3 study, the most rigorous clinical trial of renal denervation to date, failed to meet its primary endpoint. The procedure also has other limitations such as the lack of long term, efficacy and safety data and the lack of the predictors for the blood pressure lowering response and nonresponse to the procedure. An overview of current renal denervation devices holding Conformite Europ6enne mark is also included in this review. Conclusions Renal denervation is a promising therapeutic approach in the management of resistant hypertension and other diseases characterized by sympathetic overactivity. In its early stage of clinical application, the efficacy of the procedure is still controversial. Large scale, blind, randomized, controlled clinical trials are still necessary to address the limitations of the procedure.

唐代翰林学士制诰文本生成机制主要包括三个阶段:第一阶段是制诰文本的初期构成阶段。此阶段文本用语与前置文本体式、预设话语密切相关。第二阶段是制诰文本雏形的生成阶段。这主要分为翰林学士撰写、“诏意”撰写等两种模式。在各方力量的作用下,文本显性面貌(或说置顶文本层)遵循“尊君重诏”“斟字酌句”“奖饰语修之”等原则。第三阶段是制诰文本的反馈修正阶段。君主、门下省、尚书省等是主要参与者,其反馈修正“以古义谟诰为准的”。可见,制诰文本的生成具有多阶段性,而文本样貌具有多层次性。

作者： binghui wang Xupin Zhuang Wenjian Deng Bowen Cheng 不详

Silver nanoparticles were prepared by microwave irradiation of silver nitrate solution with carboxymethyl chitosan as reducing agent and a stabilizer. The optical properties, morphology and structure were characterized using UV–Visible spectrophotometer, transmission electron microscope (TEM) and X-ray diffraction (XRD). Appearance of surface plasmon band at 413 nm indicated the formation of silver nanoparticles within 5 s microwave irradiation. TEM images show most silver nanoparticles are between 2 nm and 20 nm. XRD results identified the nanoparticles as face-centered cubic phase.

本文研究价格管制导致的IPO时机选择现象。A股市场中IPO的发行价格受到管制,给公司带来不小的融资成本,研究发现,公司为了减少管制所带来的融资成本,会针对这种管制定价方式选择IPO时机,表现为:当公司的成长性较高时,将不愿意进行IPO,而会选择推迟上市,待其成长性实现后,当前盈利更高时才在A股市场IPO。海外资本市场不存在价格管制,公司去海外上市不需要根据其成长性进行IPO的时机选择,这使得海外资本市场上中国IPO公司的成长性要高于A股市场IPO公司。交叉上市的公司也多选择先海外上市,后回归A股市场。中国特殊的IPO定价制度使得A股市场成为一个低成长性市场。

近年来,西北太平洋地区的海洋垃圾问题日益严重。由于受到季风和洋流的影响,大量海洋垃圾由一国附近海域漂流到邻国。然而,现阶段垃圾检测技术和垃圾来源追踪技术尚无法甄别责任主体,从而引发了相邻各国互相推诿责任的现象。解决海洋垃圾纠纷问题的最终有效路径就是加强多边协作机制,完善共同专项基金。
