We show how to systematically construct higher-derivative terms in effective actions in harmonic superspace despite the infinite redundancy in their description due to the infinite number of auxiliary fields. Making an assumption about the absence of certain superspace Chern-Simons-like terms involving vector multiplets, we write all 3and 4-derivative terms on Higgs, Coulomb, and mixed branches...

BACKGROUND Relatively low levels of brain N-acetylaspartate, as measured by magnetic resonance spectroscopy, may indicate decreased neuronal density or viability. Dorsolateral prefrontal levels of N-acetylaspartate have been reported to be decreased in adults with bipolar disorder. We used proton magnetic resonance spectroscopy to investigate dorsolateral prefrontal N-acetylaspartate levels in ...

Intracellular polyamine pools are homeostatically maintained by processes involving biosynthesis, catabolism, and transport. Although most polyamine-based anticancer strategies target biosynthesis, we recently showed that activation of polyamine catabolism at the level of spermidine/spermine N-acetyltransferase-1 (SSAT) suppresses tumor outgrowth in a mouse prostate cancer model. Herein, we exa...

We show how to multiply two n × n matrices over semirings in the Congested Clique model, where n nodes synchronously communicate in an all-to-all manner using O(log n)-bit messages, within a round complexity that depends on the number of non-zero elements in the input matrices. By leveraging the sparsity of the input matrices, our algorithm reduces communication costs and thus improves upon the...

stabilization/ solidification (s/s) of hazardous waste by hydraulic binders is one of the mostpromising ways to reduce the polluting nature of ultimate waste. this study conducted at the laboratory scale, to study of the influence of various parameters namely: the ratio l/s, the contact time solid/liquid, surface and medium of exposure...etc., on the environmental impact of ultimate waste synth...

Changes in the skin that occur in the elderly may put them at increased risk for altered percutaneous penetration from pharmacotherapy along with potential adverse effects. Skin factors that may have a role in age-related percutaneous penetration include blood flow, pH, skin thickness, hair and pore density, and the content and structure of proteins, glycosaminoglycans (GAGs), water, and lipids...

The [35S]methionine-labeled proteins released in the medium conditioned by normal and transformed mouse fibroblasts have been analyzed by sodium dodecyl sulfate-polyacrylamide electrophoresis. Three major proteins, fibronectin, procollagens, and a protein with a molecular weight of 45,000 (45K protein) have been identified. The 45K protein, which has not yet been described, accounts for about 3...

Interactions between filters tuned to different orientations and gpatial Iocatiom were investigated with a masking paradigm. Targets were masked by pairs of Gabor signals presented either at a different orientation (*A(I)or at a different spatial location (&Ay).The two mask components were either of equal phase or of opposite phase to each other. Detection thresholds of the target were measured...
