AuBr3-catalyzed azidation of per-O-acetylated and per-O-benzoylated sugars

Herein we report, for the first time, the successful anomeric azidation of per-O-acetylated and per-O-benzoylated sugars by catalytic amounts of oxophilic AuBr3 in good to excellent yields. The method is applicable to a wide range of easily accessible per-O-acetylated and per-O-benzoylated sugars. While reaction with per-O-acetylated and per-O-benzoylated monosaccharides was complete within 1-3...

On-line Variance Minimization in O(n2) per Trial?

Consider the following canonical online learning problem with matrices [WK06]: In each trial t the algorithm chooses a density matrix Wt ∈ Rn×n (i.e., a positive semi-definite matrix with trace one). Then nature chooses a symmetric loss matrix Lt ∈ Rn×n whose eigenvalues lie in the interval [0, 1] and the algorithms incurs loss tr(WtLt). The goal is to find algorithms that for any sequence of t...

Substrate control through per-O-methylation of cyclodextrin acids.

Per-O-methylated cyclodextrins containing a single 2-O-(2-acetate), 2-O-(3-propanoate) or a 6-carboxylate were investigated for glycosidase activity on p-nitrophenyl glycosides. The former two compounds displayed enzyme catalysis giving rate accelerations of 500-1000, while the latter compound gave marginal catalysis. These results show that per-O-methylated cyclodextrins direct substrate bindi...

Disk I/O Performance-per-Watt Analysis for Cloud Computing

Assessing disk I/O performance and power consumption associated with a given cloud workload is important especially for workloads that are bounded by disk I/O. Disk performance becomes a bottleneck for achieving higher performance and lower power consumption especially when memory size is not enough to process large blocks of data. This will lead to a negative impact on the Quality-of-Service (...
