A preliminary checklist of lichen-forming and lichenicolous fungi Castilla-La Mancha is presented. total 5064 records have been compiled from 204 publications. The number taxa ascends to 832, which 820 are species 12 infraspecific taxa. Of these 763 lichenized 69 correspond fungi.
Abstract Beyond well-assessed risk factors, cardiovascular events could be also associated with the presence of epigenetic and genetic alterations, such as methylenetetrahydrofolate-reductase (MTHFR) C677T polymorphism. This gene variant is related to increased circulating levels homocysteine (Hcy) risk. However, heterozygous carriers have an augmented accidents independently from normal Hcy le...
CEP161 is a novel component of the Dictyostelium discoideum centrosome which was identified as binding partner of the pericentriolar component CP250. Here we show that the amino acids 1-763 of the 1381 amino acids CEP161 are sufficient for CP250 binding, centrosomal targeting and centrosome association. Analysis of AX2 cells over-expressing truncated and full length CEP161 proteins revealed def...
The X-ray crystallography problem is to reconstruct a crystalline structure from the Fourier magnitude of its diffracted scattering data. This has three major difficulties: (1) Only Fourier magnitude (not phase) data are known; (2) There is no support constraint (since the crystal is periodic); and (3) only low-wavenumber scattering data are available. But it also has two major advantages: (1) ...
The limited angle tomography problem is to reconstruct an image from a set of its projections (Radon transform) over a limited range of angles. It has applications in medical imaging and synthetic aperture radar. From the Radon projectionslice theorem, this problem is equivalent to image reconstruction from partial Fourier data. This paper presents an algorithm for solving this problem for spar...
Telerobots, remotely controlled robots, are widely used to explore undersea terrains and outer space, to defuse bombs, and to clean up hazardous waste. Until 1994, telerobots were accessible only to trained and trusted experts through dedicated communication channels. This chapter describes networked telerobots, a new class of telerobots controllable over networks such as the Internet, that are...
The problem of computing sparse (mostly zero) solutions to underdetermined linear systems of equations has received much attention recently, due to its applications to compressed sensing. Under mild assumptions, the sparsest solution has minimum-L1norm, and can be computed using linear programming. We present a non-iterative algorithm for this problem that requires only that each row of the sys...
