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...

Abstract. In dimension 2, the Horgan-Payne angle serves to construct a lower bound for the inf-sup constant of the divergence arising in the so-called LBB condition. This lower bound is equivalent to an upper bound for the Friedrichs constant. Explicit upper bounds for the latter constant can be found using a polar parametrization of the boundary. Revisiting carefully the original paper which e...

We construct a new family of homomorphisms between (graded) Specht modules of the quiver Hecke algebras of type A. These maps have many similarities with the homomorphisms constructed by Carter and Payne in the special case of the symmetric groups, although the maps that we obtain are both more and less general than these.

With the public discussion mainly revolving around deterrence (either by denial or by punishment), there are actually a number of strategies which can be applied to cyber operations. A cyber strategy can be thought of as an umbrella for various individual cyber operations with the ultimate aim to achieve a strategic and / or political goal. Thus, cyber strategies can be defined as the developme...
