Shun Xu: a benevolent doctor

2 Shun -

A Fock space is introduced which admits an action of a quantum group of type A supplemented with some extra operators. The canonical and dual canonical basis of the Fock space are computed and then used to derive the finite-dimenisonal tilting and irreducible characters for the Lie superalgebra osp(2|2n). We also determine all the composition factors for the symmetric tensors of the natural osp...

A Case for Benevolent Viruses

We begin with some background on viruses and related topics in ‘life-like’ computational organisms. Next we examine some of the major problems facing the current global computing environment and how viruses have the potential for helping to solve these problems. We then consider several widely stated arguments against the application of computer viruses for useful purposes and provide counterpo...

A selective and sensitive liquid chromatography-tandem mass spectrometry method was developed and validated for quantitation of bupropion (BUP) and its metabolite hydroxybupropion (HBUP) in rat plasma and urine using carbamazepine as an internal standard. Chromatographic separation was achieved on a SB-C18 column at 30 °C, using the gradient elution of 0.1 % formic acid in water and acetonitril...

In this study, a simple, rapid and sensitive ultra performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) method is described for determination of voriconazole in rat plasma samples using pirfenidone as the internal standard (IS) from pharmacokinetic assays. Sample preparation was accomplished through a simple protein precipitation with acetonitrile, and chromatographic separat...
