Ectopic valvular ossification during the course of degenerative valve disease is a relatively rare event. The presence of lamellar bone tissue in human cardiac valve was first documented histologically by Rosenstein over a century ago (1). The frequency of ossification in surgically excised native cardiac valves reported in three large retrospective analyses was 13% (aortic and mitral valves) (...

sactions Algorithms for Noncoherent lis Coded odulation

Noncoherent decoding of trellis codes using multiplesymbol overlapped observations was shown previously to achieve close to the coherent performance. Optimal decoding by the ViterBi algorithm for L-symbol observations requires a number of states which grows exponentially with L. In this paper, two novel suboptimal algorithms are presented, for which the number of states is the same as the origi...

LIS meets the EIP

To meet a perceived need for information professionals engaging in projects on document and knowledge management, a new course on Enterprise Information Portals (EIP) and Intranets has been established at the Royal School of Library and Information Science (RSLIS). The aim of the course has been to provide the graduates with a better understanding of fundamental theoretical, methodological and ...

LIS-less neurons fall behind

IS1, the protein that is affected in the developmental disorder Lissen-cephaly, interacts with cytoplasmic dynein in several cell systems. As neuronal positioning is disrupted by this disease, LIS1 and dynein are assumed to be involved in neuronal migration. Now, live in vivo images from Tsai et al. (page 935) reveal that migration is just one facet of LIS1 function. Neuronal development was bl...
