Werner syndrome is a rare autosomal recessive disorder characterized by multiple features consistent with accelerated aging. It is caused by mutations in the WRN gene, which encodes a RecQ type helicase. To date, more than 70 disease-causing mutations have been reported. While founder mutations and a corresponding relatively high incidence of WS have been reported in Japan and Sardinia, such mu...

In this paper, we write down the separable Werner state in a two-qubit system explicitly as a convex combination of product states, which is different from the convex combination obtained byWootters’ method. TheWerner state in a two-qubit system has a single real parameter and varies from inseparable state to separable state according to the value of its parameter. We derive a hidden variable m...

Introduction Several deconvolution methods have been proposed to increase the angular resolution of HARDI or QBI [1][2]. However, there is no deconvolution method directly applied to diffusion ODF without resorting to spherical decomposition. In this study, we developed a deconvolution method that could be directly applied to diffusion ODF, thus extending its applicability to other q-space meth...

This paper studies the inverse of min-plus convolution, i.e., min-plus deconvolution, in the set of non-negative, wide-sense increasing and causal functions. A sufficient condition for min-plus deconvolution to be closed in this set of functions is presented. Possible application of min-plus deconvolution to the service curve design has been discussed. Key-Words: Min-plus convolution, inverse p...

Blind deconvolution problems arise in many image restoration applications. Most available blind deconvolution methods are iterative. Recently, Justen and Ramlau proposed a novel non-iterative blind deconvolution method. The method was derived under the assumption of periodic boundary conditions. These boundary conditions may introduce oscillatory artifacts into the computed restoration. We desc...

In the present paper the cross norm criterion for separability of density matrices is studied. In the first part of the paper we determine the value of the greatest cross norm for Werner states, for isotropic states and for Bell diagonal states. In the second part we show that the greatest cross norm criterion induces a novel computable separability criterion for bipartite systems. This new cri...

Everybody writes about Abraham Gottlob Werner (1749-1817) but hardlv anyone rea.ds him. Werner, after whom Cuvier wrote and whole societies named themselves, has passed into modem textbooks (thanks to Lyell) as a stra,w man whose fallacious views were finally and irrevocably refuted by Ilutton and Playfair. Wer:rer was not particularly original in emphasizing the sedimentary process (neptunism)...
