摘要： A method and system of recovery point data view shift through a direction-agnostic roll algorithm is disclosed. In one embodiment, a method includes forming a data view around a recovery point, and shifting the data view around the recovery point through a direction-agnostic roll algorithm that uses at least one of a roll-forward algorithm to shift the data view to a time before the recovery point and a roll-backward algorithm to shift the data view to a time before the recover point. A data integrity may be determined to be consistent at the recover point by examining data and meta-data associated with the recovery point. The recovery point may be associated with at least one of an automatically generated event, a user definable event, and a prepackaged event. A marker data may be generated at the recovery point to enable the direction-agnostic roll algorithm to reduce a recovery time objective when an algorithm is applied.

摘要： The invention relates to a film comprising greater than 80 wt % single-wall carbon nanotubes wherein the tensile modulus is at least about 6 GPa at 0.2% strain and the conductivity of the film is at least about 70,000 S/m. The tensile modulus is typically about 8 GPa at 0.2% strain. The method for making the film comprises preparing a solution of single-wall carbon nanotubes in a superacid, such as oleum containing approximately 20 to 30% sulfur trioxide, under a dry, oxygen-free atmosphere. The solution is placed on a surface in a moisture-containing atmosphere, wherein the solution absorbs moisture and acid leaches out. The film is washed to further remove acid, dried, and, optionally, subjected to a heat treatment. Besides free-standing films, coatings of single-wall carbon nanotubes can be made on a variety of surfaces including polymers, glass, metals, and ceramics. The surfaces can be flat planes, fibers or contour shapes.

摘要： The present invention relates to a high modulus macroscopic fiber comprising single-wall carbon nanotubes (SWNT) and an acrylonitrile-containing polymer. In one embodiment, the macroscopic fiber is a drawn fiber having a cross-sectional dimension of at least 1 micron. In another embodiment, the acrylonitrile polymer-SWNT composite fiber is made by dispersing SWNT in a solvent, such as dimethyl formamide or dimethyl acetamide, admixing an acrylonitrile-based polymer to form a generally optically homogeneous polyacrylonitrile polymer-SWNT dope, spinning the dope into a fiber, drawing and drying the fiber. Polyacrylonitrile/SWNT composite macroscopic fibers have substantially higher modulus and reduced shrinkage versus a polymer fiber without SWNT. A polyacrylonitrile/SWNT fiber containing 10 wt % SWNT showed over 100% increase in tensile modulus and significantly reduced thermal shrinkage compared to a control fiber without SWNT. With 10 wt % SWNT, the glass transition temperature of the polymer increased by more than 40° C.

摘要： A method and apparatus for making aromatic heterocyclic polymeric fibers having enhanced compressive strength are disclosed. Individual polymeric fibers, while being made according to otherwise conventional methods, are full twisted as they are drawn from a spinnerette hole so that their internal fibrils and microfibrils become entangled. The twisting is performed before coagulation of the fibers. The entangled fibrils and microfibrils are believed to provide mutual support to adjacent fibrils/microfibrils to resist buckling under compression.

摘要： In a method of making a carbon fiber, carbon nanotubes (CNT) are mixed into a solution including polyacrylonitrile (PAN) so as to form a CNT/PAN mixture. At least one PAN/CNT fiber is formed from the mixture. A first predetermined electrical current is applied to the PAN/CNT fiber until the PAN/CNT fiber is a stabilized PAN/CNT fiber. A heatable fabric that includes a plurality of fibers that each have an axis. Each of the plurality of fibers includes polyacrylonitrile and carbon nanotubes dispersed in the polyacrylonitrile in a predetermined weight percent thereof and aligned along the axes of the plurality of fibers. The plurality of fibers are woven into a fabric. A current source is configured to apply an electrical current through the plurality of fibers, thereby causing the fibers to generate heat.

摘要： WD-repeat proteins are very diverse, yet these are structurally related proteins that participate in a wide range of cellular functions. WDR13, a member of this family, is conserved from fishes to humans and localizes into the nucleus. To understand the in vivo function(s) of Wdr13 gene, we have created and characterized a mutant mouse strain lacking this gene. The mutant mice had higher serum insulin levels and increased pancreatic islet mass as a result of the enhanced beta cell proliferation. While a known cell cycle inhibitor, p21, was down regulated in the mutant islets overexpression of WDR13 in the pancreatic MIN6 cell line resulted in upregulation of p21, accompanied by retardation of cell proliferation. We suggest that WDR13 is a novel negative regulator of the pancreatic beta cell proliferation. Co-immunoprecipitation experiments showed that this protein interacts with estrogen receptors and various HDACs. We provide evidence to show that WDR13 can regulate estrogen receptors-mediated transcription both in HDAC-dependent and HDAC-independent manner. Given the higher insulin levels, better glucose clearance and the lack of insulin resistance in WDR13 deficient mice, we propose that this protein may be a potential candidate drug target for ameliorating impaired glucose metabolism in diabetes.

摘要翻译： WD重复蛋白是非常多样化的，但这些是参与广泛细胞功能的结构相关蛋白。 WDR13，这个家庭的成员，从鱼类保存到人类，并定位到核心。 为了了解Wdr​​13基因的体内功能，我们创建并表征了缺乏该基因的突变小鼠株。 由于增强的β细胞增殖，突变小鼠具有较高的血清胰岛素水平和胰岛素的增加。 虽然已知的细胞周期抑制剂p21在胰岛MIN6细胞系中突变型胰岛过表达WDR13中下调，导致p21上调，伴随着细胞增殖的延迟。 我们建议WDR13是胰腺β细胞增殖的新型负调节因子。 共免疫沉淀实验显示，该蛋白质与雌激素受体和各种HDAC相互作用。 我们提供证据表明，WDR13可以调节雌激素受体介导的转录，无论是HDAC依赖型还是HDAC独立型。 鉴于WDR13缺陷小鼠胰岛素水平升高，葡萄糖清除率更高，胰岛素抵抗不足，我们建议该蛋白可能是改善糖尿病中糖代谢紊乱的潜在候选药物靶点。
