In a method of making a high surface area carbon material, a precursor organic material is prepared. The precursor organic material is subjected to a first elevated temperature while applying a gaseous purge thereto for a first predetermined time. The precursor organic material is subjected to a second elevated temperature while not applying the gaseous purge thereto for a second predetermined time after the first predetermined time. A high surface area carbon material includes carbon and has a surface area in a range between 3029 m2/g to 3565 m2/g and a pore volume in a range between 1.66 cm3/g and 1.90 cm3/g. The high surface area carbon material may be employed in an electrode for a supercapacitor.

In a method of making a carbon fiber, polyacrylonitrile is dissolved into a first solvent, thereby generating a first solution. A plurality of cellulose nano-structures is dispersed in a second solvent, thereby generating a first suspension. The first suspension is mixed with the first solution, thereby generating a first mixture. The first mixture is spun so as to draw fibers from the first mixture. The fibers are stabilized and then the fibers are carbonized. A fiber includes an elongated carbonized polyacrylonitrile matrix. A plurality of carbonized cellulose nano-structures is in the carbonized polyacrylonitrile matrix.

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.

Methods, software suites, and systems of generating a recovery snapshot and creating a virtual view of the recovery snapshot are disclosed. In an embodiment, a method includes generating a recovery snapshot at a predetermined interval to retain an ability to position forward and backward when a delayed roll back algorithm is applied and creating a virtual view of the recovery snapshot using an algorithm tied to an original data, a change log data, and a consistency data related to an event. The method may include redirecting an access request to the original data based on a meta-data information provided in the virtual view. The method may further include substantially retaining a timestamp data, a location of a change, and a time offset of the change as compared with the original data.

摘要:
A geometric pattern matching method to locate instances of a template image in a target image using a plurality of models with different feature combinations. A learning phase involves learning geometric information about the template image and creating a model for each of a plurality of different respective parent features. Each model comprises a relationship tree from the respective parent feature to one or more other child features, and hence each model may have different feature combinations. In a matching phase, the method may examine a plurality of different models to determine matches in the target image being analyzed. The matching phase may select different models dynamically based on prior matching results.
