Abstract We expand upon work from many hands on the decomposition of nuclear maps. Such maps can be characterised by their ability to approximately written as composition and matrices. Under certain conditions (such quasidiagonality), we find a whose behave nicely, preserving multiplication up an arbitrary degree accuracy being constructed order-zero (as in definition dimension). investigate th...

This paper deals with structural issues concerning wavelet frames and their dual frames. It is known that there exist { a j / 2 ? ( ? ? k b ) } , ? Z in L R for which no frame has structure. We first generalize this result by proving approximately Motivated we show imposing very mild decay condition on the Fourier transform of generator certain oversampling N indeed an frame; most importantly, ...

Objective: This study aimed to assess whether currently used dosages of vancomycin for treatment of serious gram-positive bacterial infections in intensive care unit patients provided initial therapeutic vancomycin trough levels and to examine possible factors associated with the presence of adequate initial vancomycin trough levels in these patients. Methods: A prospective descriptive study ...
