Abstract: Various embodiments are directed to a central executive training (CET) platform that targets central executive processes, rather than short term memory. Central executive deficits have been linked experimentally and developmentally with Attention Deficit Hyperactivity Disorder (ADHD) symptoms and impairments. Unfortunately, substantial evidence indicates that conventional working memory training programs fail to improve these symptoms and impairments. This discrepancy may reflect insufficient targeting, as extant protocols focus on short term memory and do not adequately engage the specific central executive components linked with the disorder's behavioral and functional impairments.

Abstract: Certain embodiments herein relate to, among other things, designing data cache systems to enhance energy efficiency and performance of computing systems. A data filter cache herein may be designed to store a portion of data stored in a level one (L1) data cache. The data filter cache may reside between the L1 data cache and a register file in the primary compute unit. The data filter cache may therefore be accessed before the L1 data cache when a request for data is received and processed. Upon a data filter cache hit, access to the L1 data cache may be avoided. The smaller data filter cache may therefore be accessed earlier in the pipeline than the larger L1 data cache to promote improved energy utilization and performance. The data filter cache may also be accessed speculatively based on various conditions to increase the chances of having a data filter cache hit.

Abstract: A method to determine the distribution of non-reactive sulfur compounds and reactive sulfur compounds in petroleum samples by separating non-reactive sulfur compounds from reactive sulfur compounds in a petroleum composition includes the step of contacting the petroleum composition with a Ag-containing cation exchange media. The petroleum composition and the Ag-containing cation exchange media are contacted with a non-reactive sulfur compound solvent capable of eluting the non-reactive sulfur compounds in the presence of the Ag-containing cation exchange media and incapable of eluting the reactive sulfur compounds in the presence of the Ag-containing cation exchange media at the conditions of the exchange. The non-reactive sulfur compounds are eluted from the media with the non-reactive sulfur compound solvent to provide a first fraction. The amount of non-reactive sulfur compounds in the first fraction is then determined.

Abstract: The disclosure is directed to a set of multi-coordinating imidazole- and zwitterion-based ligands suited for surface-functionalizing quantum dots (QDs).

Abstract: The subject invention pertains to acellular extracellular matrix (ECM) and methods for preparing it. In one embodiment, the ECM is prepared from 3-D aggregates of pluripotent stem cells or from embryoid bodies. In one embodiment, the ECM is in the form of acellular microspheres. The stem cells used in the present invention can be embryonic stem cells (ESC). In a specific embodiment, the stem cells or embryoid bodies are from human. The ECM of the invention can be mass produced using PSC aggregates or embryoid bodies in large scale bioreactors. The acellular ECM produced using the present invention can be used for injection into a person or animal to regenerate tissue and/or treat a disease or condition. A method of the invention comprises growing stem cells in suspension culture as aggregates, e.g., in a bioreactor. Acellular ECM is then prepared from the cell aggregates by decellularization.

Abstract: The present invention includes a system and method for defending against unwanted observations of the information conveyed by electronic devices. The system allows users to access sensitive information in public without the fear of visual or other observational leaks. The present invention intercepts sensitive data elements before they are conveyed to a user and replaces the sensitive data with non-sensitive information referred to as aliases. In addition, the system provides a means of computing with sensitive data in a non-observable way. All of this is accomplished while maintaining full functionality and legacy compatibility across applications.

Abstract: Identified herein is a novel post-translational modification of Mcm2, wherein the residue of serines 53 and 108 are phosphorylated. DDK phosphorylates Mcm2 at serines 53 and 108 when stimulated by Treslin. DDK is overexpressed in many human cancers, including colorectal cancer, suggesting that monitoring the phosphorylation of Mcm2 at serines 53 and 108 may detect early cancer with high sensitivity and specificity. It was also found that the homologous modification in budding yeast is required for DNA replication, and the modification occurs in cells during active DNA replication only. In an embodiment, the current invention is an antibody specific for human Mcm2 that is phosphorylated at serines 53 and 108. This antibody was found to be overexpressed in colon cancer cell line HCT 116, as well as other cancer cell lines, compared to normal cells.

Abstract: A sample preparation device for electron microscopy (EM) that is configured to eliminate user-to-user variations and environment contaminations, which are often present in the conventional method of sample preparation. The device not only provides a means for evenly and reproducibly delivering a fluid or sample to an EM grid, but also provides a means for sealing the EM grid in an air-tight chamber and delivering air-sensitive samples to the EM grid. The platform may comprise readily fabricated glass chips with features integrated to preserve the integrity of the sample grid and to facilitate its extraction. The methods may eliminate the element of user dependent variability and thus improve the throughput, reproducibility and translation of these methods.
