Using high frequency (up to 450 GHz) ESR and low temperature specific heat measurements we find that insertion of 1% Fe and 2% Co damps spin-Peierls and Neel transitions and for T <30K may give rise to onset of a quantum critical behaviour characteristic for a Griffiths phase. Most of the available data for doped inorganic spin-Peierls compound CuGeO 3 correspond to the limit of weak disorder w...

As the logical next step after sequencing the mouse genome, biologists have developed laboratory methods for rapidly determining where each of the 30K genes in the mouse genome is synthesizing protein. Applying these methods to the mouse brain, biologists are currently generating large numbers of 2D cross-sectional images that record the expression pattern for each gene in the mouse genome. In ...

We observed the upper fine structure line of neutral carbon, C I(P2 →P1) (νrest = 809 GHz), the 12CO(J=3→2) line (νrest = 345 GHz) and the 1.2 mm continuum emission from H1413+117 (Cloverleaf quasar, z = 2.5) using the IRAM interferometer. Together with the detection of the lower fine structure line (Barvainis et al. 1997), the Cloverleaf quasar is now only the second extragalactic system, besi...

Rice yellow stunt rhabdovirus (RYSV) encodes seven genes in its negative-sense RNA genome in the order 3'-N-P-3-M-G-6-L-5'. The existence of gene 3 in the RYSV genome and an analogous gene(s) of other plant rhabdoviruses positioned between the P and M genes constitutes a unique feature for plant rhabdoviruses that is distinct from animal-infecting rhabdoviruses in which the P and M genes are di...

We study high-field spin transport of electrons in a quasi one-dimensional channel of a GaAs gate controlled spin interferometer (SPINFET) using a semiclassical formalism (spin density matrix evolution coupled with Boltzmann transport equation). Spin dephasing (or depolarization) is predominantly caused by D’yakonov-Perel’ relaxation associated with momentum dependent spin orbit coupling effect...

BACKGROUND Troglitazone (TRO), a novel antidiabetic drug, has been reported to decrease blood pressure and relax vascular strips. The mechanism of relaxation induced by TRO was determined in terms of Ca2+ signaling in smooth muscle cells. METHODS AND RESULTS Front-surface fluorometry and fura 2-loaded medial strips of porcine coronary artery were used to examine the effects of TRO on cytosoli...

This paper describes a series of experiments that compare different approaches to training a speakerindependent continuous-speech digit recognizer using the CSLU Toolkit. Comparisons are made between the Hidden Markov Model (HMM) and Neural Network (NN) approaches. In addition, a description of the CSLU Toolkit research environment is given. The CSLU Toolkit is a research and development softwa...

We report single-step vacuum growth of stoichiometric superconducting thin films of MgB2, using AASC’s cathodic arc deposition process. Energetic condensation using cathodic arcs produces non-equilibrium fast ions (~50-100eV) that allow growth modes on relatively low temperature substrates. We have demonstrated MgB2 films with Tc of 34K by depositing at 275 °C in a single step, from a stoichiom...

1 S U P E R C O N D U C T O R S INTRODUCTION Superconductivity is a phenomena displayed by certain metallic and ceramic materials whose electrical resistance falls to zero at a specific critical temperature. Unfortunately, until very recently, the temperatures were so cold that they were attainable only with the use of liquid helium. In 1986, IBM researchers Georg Bednorz and Alex Müller report...

The synthesis of the two respiratory syncytial (RS) virus glycoproteins (VP66 and VP84) was examined under standard conditions and after treatment with tunicamycin and monensin. The protein backbone for VP66, the fusion protein (F1,2) is cotranslationally glycosylated to form F0, which is cleaved to form F1,2 by 20 min of chase. Monensin treatment inhibited the cleavage of F0 over an 80 min cha...
