Nitrogen functionality is ubiquitous in biologically active molecules, from naturally occurring alkaloids and peptides to synthetic pharmaceuticals. However, due to its promiscuous reactivity, nitrogen can be challenging ...

A one-pot C2-amidoglycosylation reaction for the synthesis of 2-N-acylamino-2-deoxypyranosides from glycal donors has been developed. In the reaction, activation of glycal donor by a sulfoxide and triflic anhydride followed ...

The use of a private cache in each processor of large-scale shared-memory multiprocessor systems can reduce long global memory latency but also introduces the cache coherence problem. Cache design and performance in a ...

Dependable real-time systems are essential to time-critical applications. The systems that run these applications require high degrees of performance and predictability. Although memory caching has long been known as a ...

To recompute from scratch, cache, or maintain a running-total is a database optimization question. The best answer depends in part upon usage patterns. For example, is total accessed frequently, or is the underlying table ...

Cadherins are calcium dependent cell adhesion molecules. The interaction between cadherin molecules is important in establishing cell polarity, tissue identity and tissue boundary. This study focused on the mechanism of ...

Broad band gain on the B(--->)X bands of ZnI and CdI has been obtained in 13 and 25 cm active length, UV-preionized, high temperature (440(DEGREES)C), transverse discharge devices. With a 50 cm active length device, ...

In October, 1978, the Government of India launched the National Adult Education Programme (NAEP) for 100 million illiterate adults ages 15 to 35. The program was intended, in five years, to provide 10-month courses in ...
