In the mol-ecular structure of the title compound, C(10)H(11)NOS, the central six-membered ring of the indolizine unit adopts an envelope conformation, the maximum deviations from the mean plane of the ring being 0.533 (2) Å. The fused thieno ring is nearly coplanar [mean deviation = 0.007 (2) Å]. The conformation of the fused oxopyrrolidine ring is close to that of a flat-envelope, with a maxi...
In the title compound, C(15)H(10)FN(5)O(3)S, an intra-molecular N-H⋯N hydrogen bond generates an S(5) ring, whereas N-H⋯O and C-H⋯S inter-actions complete S(6) ring motifs. The dihedral angle between the isatin ring system and the fluoro-benzene ring is 5.96 (6)° and the complete mol-ecule is close to planar (r.m.s. deviation for all the non-H atoms = 0.112 Å). In the crystal, mol-ecules are li...
We present a case with a small extra ring chromosome which was found in 66% of lymphocytes on routine cytogenetic examination. FISH analyses, using centromere specific and single copy probes, showed that the extra ring chromosome was derived from the most proximal part of 10p, close to the centromere. The patient has a unilateral cleft lip and palate, mild dysmorphic features, and mild mental r...
The classic Leftover Hash Lemma (LHL) is often used to argue that certain distributions arising from modular subset-sums are close to uniform over their finite domain. Though very powerful, the applicability of the leftover hash lemma to lattice based cryptography is limited for two reasons. First, typically the distributions we care about in lattice-based cryptography are discrete Gaussians, n...
In this paper, we propose a new score normalization method for text-independent speaker verification using GMM (Gaussian Mixture Model). In the proposed method, cohort model is designed as virtual speaker model based on the similarity of local acoustic information between the reference speaker and other customers. The similarity is determined using statistical distance between model components ...
The ideal choices for the tasks presented in the project proposal would be the NVIDIA CUDA toolkit (http://developer.nvidia.com/object/cuda. html), which exposes more underlying architecture to programmers. However, the package requires a capable NVIDIA video card, and we could not get for this project. ATI also designed a similar platform “Close-to-Metal (CTM) Device” (http://ati.de/companyinf...
Electroencephalogram (EEG) from dorsal cortex of lizard Gallotia galloti was analyzed at different temperatures to test the presence of fractal or nonlinear structure during open (OE) and closed eyes (CE), with the aim of comparing these results with those reported for human slow-wave sleep (SWS). Two nonlinear parameters characterizing EEG complexity [correlation dimension (D2)] and predictabi...
A fully automatic algorithm is developed for breast arterial calcification extraction in mammograms. This algorithm is implemented in two major steps: a random-walk based tracking step and a compiling and linking step. With given seeds from detected calcification points, the tracking algorithm traverses the vesselness map by exploring the uncertainties of three tracking factors, i.e., traversin...
We explain that the anomalous frequency shifts of very close masses obtained in the high precision mass measurement experiments in the ESR storage ring result from the locking of Coulomb interacting strings of ions. Here two concentric strings which run horizontally close to each other are captured into a single string if their thermal clouds overlap and give up their identity.
