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, ...

Detailed studies correlating changes in mitochondrial optical density, packed volume, and ultrastructure associated with osmotically-induced swelling were performed. Various swelling states were established by incubating mitochondria (isolated in 0.25 M sucrose) at 0 degrees C for 5 min in series of KCl and sucrose solutions ranging in tonicity from 250 to 3 milliosmols. Reversibility of swelli...

Members of the LC7/Roadblock family of light chains (LCs) have been found in both cytoplasmic and axonemal dyneins. LC7a was originally identified within Chlamydomonas outer arm dynein and associates with this motor's cargo-binding region. We describe here a novel member of this protein family, termed LC7b that is also present in the Chlamydomonas flagellum. Levels of LC7b are reduced approxima...

we prove the generalized hyers--ulam stability  of n--th order linear differential equation of the form $y^{(n)}+p_{1}(x)y^{(n-1)}+ cdots+p_{n-1}(x)y^{prime}+p_{n}(x)y=f(x)$, with condition that there exists a non--zero solution of corresponding homogeneous equation. our main results extend and improve the corresponding results obtained by many authors.
