Silent stores, i.e., stores to memory that write the same value as already stored in that memory location, have been observed to occur frequently. These stores not only create redundant memory transactions, but in a multiprocessor environment result in redundant communication messages. In this paper, we quantify the frequency of such silent stores, in particular temporally silent stores, in typ...

We present a multi-wavelength (NIR to radio) and multi-scale (1 AU to 10 pc) study of the S255–S257 complex of young high-mass (proto)stars. The complex consists of two evolved HII regions and a molecular gas filament in which new generations of high mass stars form. Four distinct regions are identified within this dusty filament: a young NIR/optical source cluster, a massive protostar binary, ...

Previous studies on linkage disequilibrium involving four tightly linked genes that code for the alpha-esterases of Drosophila montana suggest that these loci arose from a primitive esterase gene by gene duplication, followed by tandem duplication (Roberts and Baker 1973). We have examined the esterase variants in the closely related species, lacicola, flavomontana and borealis. These studies r...

The extraction of DNA for molecular analyses is often a limiting factor in terms of cost, time, and availability of skilled labor. Here the authors describe a simple extraction protocol for obtaining DNA from field and greenhouse grown plants. This method was optimized for sampling mature wild sorghum populations in remote areas of Ethiopia and young greenhouse grown seedlings for genetic studi...

BACKGROUND Several papers have indicated that glutamine is a preferred fuel for the enterocyte and that it can increase intestinal epithelial cell proliferation. AIMS To investigate the effects of glutamine on intestinal epithelial cell proliferation in the parenterally fed rat. METHODS Five groups of six rats were fed parenterally; a group of orally fed rats was also studied. Crypt cell pr...

The tomato clade of Solanaceae is composed of 12 species that are all diploid with the same chromosome number and morphology. Species in the tomato clade are considered to have evolved primarily by genic changes rather than large-scale chromosomal rearrangements because pachytene chromosomes in F(1) hybrids synapse normally along their lengths and linkage maps of intra- and inter-specific hybri...

Glucose content and in vitro bioaccessibility were determined in raw and cooked pulp of Arapey, Cuabé, and Beauregard sweet potato varieties, as well as Maravilla del Mercado and Atlas winter squash, after zero, two, four, and six months of storage (14 °C, 80% relative humidity (RH)). The total glucose content in 100 g of raw pulp was, for Arapey, 17.7 g; Beauregard, 13.2 g; Cuabé, 12.6 g; Atla...

Withering syndrome is a fatal disease of wild and cultured abalone, Haliotis spp., that inhabit the west coast of North America. The aetiological agent of withering syndrome has recently been identified as a member of the family Rickettsiaceae in the order Rickettsiales. Using a combination of morphological, serological, life history and genomic (16S rDNA) characterization, we have identified t...

Cucurbit Yellow Stunting Disorder Virus (CYSDV) represents a significant threat to global agriculture, particularly impacting the cultivation of cucurbit crops such as melons, squashes, and cucumbers. This comprehensive review explores various dimensions CYSDV, including its taxonomy, epidemiology, pathogenesis, diagnostic methods, management, ongoing research, broader social economic implicati...
