3461.红葡萄酒中三大多酚对小鼠背根神经节细胞钠通道电流的影响
[医药制造业] [2014-07-18]
The project proposes a novel preclinical approach to study risk factors for and neurobiology of post-traumatic stress and depression. Why risk factors. Because PTSD is the only psychiatric disorder to which there is seemingly a clear etiological agent- a traumatic event that triggers it, most animal models of PTSD concentrate on what would constitute a trauma in the studied animals. However, because the majority of people exposed to traumatic experiences actually develop PTSD the exposure to the traumatic experience is necessary, but no a sufficient condition to induce disorder. We focus on both distal (childhood adversities) and proximal (sleep restriction) potential risk factors, with high relevance to soldiers; (1) To establish an effective animal model of PTSD that would consider the contribution of risk factors to the introduction of PTSD; (2) To examine the role of sleep restriction as a proximal risk factor of PTSD; (3) To establish the role of childhood adversities as a long-term risk factor in PTSD, particularly in association with sleep restriction; (4) To develop the model as a platform for pharmacological testing of novel targets for drug development.

3462.基于多传感器的自主规划机械制造系统
[计算机、通信和其他电子设备制造业] [2014-07-18]
Current trends in precision machinery include increased adaptability,speed and reliability.This,combined with the development of artificially-intelligent automatic sensors can lead to the establishment of highly-reliable and systematic manufacturing systems.During the automation process,equipment process parameters frequently need to be adjusted to match the requirements of different processes.Thus how to best maintain normal equipment operation and stable quality through these frequent adjustments is a key issue for manufacturers.Therefore,high-quality automated production systems allowing for fast-changeover and real-time automatic detection and performance monitoring are effectively needed.

3463.使用动态批量调整大小的自适应流处理
[信息传输、软件和信息技术服务业] [2014-07-18]
The need for real-time processing of “big data” has led to the development of frameworks for distributed stream processing in clusters. It is important for such frameworks to be robust against variable operating conditions such as server failures, changes in data ingestion rates, and workload characteristics. To provide fault tolerance and efficient stream processing at scale, recent stream processing frameworks have proposed to treat streaming workloads as a series of batch jobs on small batches of streaming data. However, the robustness of such frameworks against variable operating conditions has not been explored.

3464.基于同步相量测量的风电厂惯量估测
[电力、热力、燃气及水生产和供应业] [2014-07-18]
The total inertia stored in all rotating masses that are connected to power systems, such as synchronous generations and induction motors, is an essential force that keeps the system stable after disturbances. Typically, inertias respond to disturbances voluntarily, without any control actions; however, several types of renewable generation, particularly those with power electronic interfaces, have an inertial response governed by a control function. To ensure bulk power system stability, there is a need to estimate the equivalent inertia available from a renewable generation plant. An equivalent inertia constant analogous to that of conventional rotating machines can be used to provide a readily understandable metric.

3465.用于智能电网系统的选择测量装置的能量流失比较分析
[电力、热力、燃气及水生产和供应业] [2014-07-18]
This article provides information on smart grid and smart measurement systems with a special focus on the advantages of their implementation as well as concerns present at the stage of design and component selection. The tests conducted on a selected group of measurement devices used in smart grid systems made it possible to compare power losses characteristic for these devices. In the analysis presented below, both classic inductive meters and electronic meters with various communication modems were used.

3467.即将到来的四人清洁能源技术革命
[电力、热力、燃气及水生产和供应业] [2014-07-18]
This report focuses on four technology revolutions that are here today. In the last five years they have achieved dramatic reductions in cost1 and this has been accompanied by a surge in consumer, industrial and commercial deployment. Although these four technologies still represent a small percentage of their total market (e.g. electricity, cars and lighting), they are growing rapidly. The four key technologies this report focuses on are: Onshore wind power; Polysilicon photovoltaic modules; LED lighting; and Electric vehicles.

3468.叶片测试设备的开发和商业化.合作研究和开发总结报告.CRADA编号:CRD-09-346
[电力、热力、燃气及水生产和供应业] [2014-07-18]
Blade testing is required to meet wind turbine design standards, reduce machine cost, and reduce the technical and financial risk of deploying mass-produced wind turbine models. NREL's National Wind Technology Center (NWTC) in Colorado is the only blade test facility in the U.S. capable of performing full-scale static and fatigue testing of multi-megawatt-scale wind turbine blades. Rapid growth in wind turbine size over the past two decades has outstripped the size capacity of the NWTC blade test facility leaving the U.S. wind industry without a suitable means of testing blades for large land-based and offshore turbines. This CRADA will develop and commercialize testing technologies and test equipment, including scaling up, value engineering, and testing of equipment to be used at blade testing facilities in the U.S. and around the world.

3469.雄激素受体介导细胞生长的URI调控
[医药制造业] [2014-07-18]
Androgen receptor (AR)-mediated transcription is modulated by interaction with co-regulatory proteins. We identified a novel AR repressor complex comprising of the androgen receptor co-repressor Art-27 and the transcriptional repressor URI. We found through chromatin immunoprecipitation experiments that URI depletion results in increased H3K9me3 at the promoter of the AR target gene Nkx3.1, suggesting that one mechanism of URI-mediated transcriptional repression is through chromatin modification. Art-27 was also found by ChiP to localize at the transcription start site of Nkx3.1 along with PolII. Previous results demonstrated a direct interaction between URI and the transcription factor KAP1. Because of the tight association of Art-27 with URI, we hypothesized that Art-27 also affects KAP1 activity. Immunoprecipitation of Art-27 with KAP1 revealed a direct interaction between the two proteins. Consistent with this result, knockdown of Art-27 resulted in increased expression of the KAP1 targets LINE1 and AluYa5. Overall, our findings demonstrate a new role for Art-27 in KAP1-mediated gene repression.

[电力、热力、燃气及水生产和供应业] [2014-07-18]
Determining economically viable locations for solar energy projects depends on many factors, including the level of the solar energy resource, land ownership and use, potential environmental impacts, and grid connectivity. This forum session will highlight public and freely accessible Web-based mapping applications sponsored by the U.S. Department of Energy (DOE) to aid in analyzing solar energy project siting decisions. We will discuss each of the Web applications and their associated projects and then demonstrate the tools.
