A Markov model of a finite state machine realization containing gates and memory elements each subject to internal soft errors is given and a computational method for determining the probability of state transition errors is presented. The system inputs are taken as stochasticaily driven and the long-run stationary probability distribution of the states is(More)
A novel protocol for assembling polycyclic ethers was developed and successfully applied to the synthesis of the EFGH ring system of ciguatoxin CTX3C. A key transformation involves construction of an O,S-acetal through coupling of alpha-chlorosulfide and a secondary alcohol under mild conditions. The method is highly applicable to use with sensitive(More)
[reaction: see text] An efficient route to the neocarzinostatin chromophore aglycon has been developed. The present strategy involves a stereoselective intramolecular acetylide-aldehyde cyclization to form the C5-C6 bond, followed by efficient installation of alpha-epoxide, naphthoate, and carbonate functionalities. The C8-C9-olefin was introduced by using(More)
The aim of this study is to determine the frequency of quaternary ammonium compound-resistant genes, including qacA/B, qacC/D, qacE, qacΔE1, qacG, qacJ, and β-lactamase genes, including blaCTX-M, blaTEM, blaSHV, blaOXA-23, blaVIM, blaIMP, blaNDM and blaGIM in 51 isolates of carbapenem-resistant Acinetobacter baumannii collected over a period of 2 years and(More)
A novel acromelic acid analogue containing a phenyl group possessing two different types of azido functional groups, of which one is the aromatic N3 acting as a photoaffinity group to bind to a target protein by photoirradiation and the other is alkyl N3 group which survives photolysis acting as a detecting group through the Staudinger-Bertozzi reaction to(More)
