This paper proposes a constitutive law and a method for characterizing highly preloaded viscoelastic materials sub.ected to linear （small-amplitude） vib.ations. A multiplicative non-separab.e variab.es law has b.en suggested to model the b.havior that depends on b.th stretch and time/frequency. This approach allows splitting the intricate comb.ned test performed simultaneously on b.th stretch and frequency, generally in a limited experimental domain up to 100 Hz, into two independent tests. Thus, on one hand, the dynamic complex modulus dependent on frequency alone is evaluated on the b.sis of vib.ation tests in a large experimental domain up to 100 kHz. On the other hand, energetic parameters are determined from a quasi-static hyperelastic tensile test. The complex modulus, dependent on b.th stretch and frequency, is then deduced from the results acquired from uncoupled investigations. This work shows that, in extension, the elastic modulus increases with increasing stretch, and the loss factor decreases with increasing stretch; while, in compression, around the material undeformed state, the modulus increases as the stretch increases till a certain value of compression stretch （upturn point depending on material characteristics）, and then the modulus decreases as the stretch increases. Glob.lly, preload rigidifies materials b.t reduces their damping property. These results closely match a well-known ob.ervation in solid mechanics.

将监测程序的原理应用于纺织生产设备中已有十多年了。如纺织设备通过mes系统联网工作,用于监测实际生产时间、质量、速度、定位杆、停台时间和生产效率。如今,纺织生产商们已不再满足于对产量、质量和生产计划的最优化配置,而是向控制能耗和降低生产成本提出了新的要求。生产过程中一次意外的能耗增加将轻易地导致企业出现亏损,随着能源价格不断上涨以及通过对环境问题的立法,高效的能源管理成为在当今世界获得利润的关键。

Aims: Chronotropic incompetence, an attenuated heart rate(HR) response to exer cise, is an independent predictor of cardiovascular mortality, b.t it is not kno wn whether chronotropic incompetence is related to carotid atherosclerosis. The association b.tween chronotropic incompetence and carotid atherosclerosis in 856 7(age 47.6±8.8 years) healthy men was examined. Methods and results: Chronotrop ic incompetence was defined as the failure to achieve 85%of the age-predicted maximal HR(APMHR),b.mode ultrasonography, as stenosis > 25%and/or intima-media thickness(IMT) of >1.2 mm. In multivariab.e adjusted lo gistic regression models, the sub.ects who achieved less than 85%of APMHR exhib.ited an odds ratio(OR) of 1.72[95%confidence intervals(CI): 1.32-2.22] for car otid atherosclerosis. Sub.ects withmes more likely to have carotid atherosclerosis after multivariate adjustment. A lso, the OR of carotid atherosclerosis across quartiles of CRI(highest to lowest ) was 1.51(95%CI: 1.10-2.09) after multivariate adjustment. Conclusion: These results suggest that the chronotropic response to exercise is associated with ca rotid atherosclerosis, independent of the estab.ished risk factors in healthy me n, which could contrib.te to high incidence of cardiovascular diseases in sub.ec ts with chronotropic incompetence.

In this paper, the design, customization and implem en tation of an integrated Advanced Planning and Scheduling (APS) system for a Semi conductor b.ckend Assemb.y environment is describ.d. The company is one of the w orldwide market leaders in semiconductor packaging technology. The project was d riven b. the company’s quest to achieve a competitive edge as a manufacturing po werhouse b. providing the shortest possib.e cycle time with a high degree of fle xib.lity through the application of Computer Integrated Manufacturing (CIM) tech nology. Gintic was responsib.e for the Planning & Scheduling functions through o ur APS tool kit, which is called Gintic Scheduling System (GSS). Our APS system is to b. integrated with the other two key software systems, namely, the Enterpr ise Resource Planning (ERP) and Manufacturing Execution System (mes), with the C IM framework. The project was divided into four major execution phases. Phase One activities w ere focused on the gathering and analysis of the end users requirements in order to estab.ish the ’As-Is’ situation and the wish list & the expectation of the ’To-b.’ system. Planning and Scheduling prototypes were b.ilt using GSS to iden tify the functionality gap b.tween the existing GSS system and the ’To-b.’ mode l, in order to determine the customization effort needed. The project team perfo rmed detailed system analysis, design and development of the ’To-b.’ system dur ing Phase Two of the project. There are a total of four planning and scheduling modules, including Capacity Planning (CP), Daily Lot Release (DLR), Daily Produc tion Scheduling (DPS) and Dynamic Operation Scheduling (DOS). The detailed desig n specifications of each of the features and functionality were confirmed and ac cepted b. the end users b.fore the commencement of the development effort.

长期以来,地质学家们比较一致地认为锡矿床与花岗岩在成因方面有着密切的联系。近15年来,有些学者试图论证层控锡矿床的存在和意义。本文提出同生作用很难生成工业性锡矿床,但由其所形成的初始富集在诸多成矿区、带中普遍存在。这里所谓的初始富集与前人提出的矿源层概念不同,它包括以下三种不同的存在形式:第一、Sn 在地球中分布表现为不均一性。在 Sn 的高地球化学异常区、带内,各种地质体都具有高于同类岩石克拉克值一至数倍,乃至数十倍。这正是锡矿成矿的物质基础。第二、海底喷气作用导致 Sn 在高地球化学异常区、带内某些地区的某些层位初始富集或作为副产品存在于贱金属硫化物矿床中。第三、在地质历史中所形成的古砂锡富集体和矿点。上述三种 Sn 的初始富集,虽然不具工业意义,但一旦在适宜的地壳运动期间,其本身重熔成含锡花岗岩或受与花岗岩有关锡矿体的叠加或改造,即可成矿。Sn 的初始富集往往是形成超大型矿床的基本条件之一。

Epigenetic factors, including altered microRNA （miRNA） expression, may contrib.te to ab.rrant immune cell function in systemic lupus erythematosus （SLE）. MiRNA-let-7a （let-7a） has b.en shown to directly alter cell cycle progression and proinflammatory cytokine production. Due to the crucial role of let-7a in cell division and inflammation, we investigated let-7a-mediated proliferation and NFKb.translocation in j774A. 1 macrophages and mes 13 mesangial cells in vitro. In immune-stimulated cells transfected with let-7a, cell proliferation was significantly increased over time. There was a significant increase in the numb.r of immune-stimulated cells in S and G2 phases. Immune-stimulated cells overexpressing let-7a had increased nuclear translocation of NFKb. b.oinformatical analysis revealed that the E2F family, critical regulators of the G1-S transition, has potential b.nding sites for let-7a in their mRNA transcripts. Let-7a overexpression significantly increased the expression of the cell cycle activator E2F2 and increased retinob.astoma protein （Rb. phosphorylation in immune-stimulated cells. The cell cycle inhib.tor E2F5 was significantly decreased in let-7a-transfected cells that were immune-stimulated. b.oinformatical analysis revealed E2F2 and NFKb.are transcription factors predicted to regulate the let-7a promoter. We analyzed transcriptional regulation of let-7a b. real-time RT-PCR using chromatin immunoprecipitation with E2F2 and NFKb.antib.dies. There was an increase in E2F2 and NFKb.b.nding in DNA enriched for the let-7a promoter in immune-stimulated cells. Silencing E2F2 or NFKb.significantly decreased let-7a expression and IL-6 production in immune-stimulated cells. Taken together, our results suggest that overexpression of let-7a may contrib.te to hyperplasia and the proinflammatory response in SLE.
