The Compression Functions of SHA , MD 2 , MD 4 and MD 5 are not A ne

In this paper, we show that the compressions functions of SHA, MD2, MD4 and MD5 are not a ne transformations of their inputs.

Marc Fisher , MD , and Kennedy Lees , MD Reversing Stroke in the 2010 s Lessons

Only months from now, another decade will dawn on stroke research with a dearth of therapeutic innovations developed to reverse the devastating effects of acute ischemic stroke. Despite generations of academic research investigators and associated industry collaborations, our clinical trials have marked each decade by successive eras of failed treatments with only a few exceptions. The recent p...

Md-numbers and Asymptotic Md-numbers of Operators

First, the basic properties of mean dilatation (MD-) numbers for linear operators acting from a finite-dimensional Hilbert space are investigated. Among other results, in terms of first and second order MD-numbers, a characterization of isometries is obtained and a dimension-free estimation of the p-th order MD-number by means of the first order MD-number is established. After that asymptotic M...
