Let n = pab, where p is a prime, and g.c.d.(p, b) = 1. In Pn −1, let Xr be the variety defined by rank((xi,j)) ≤ n − r. We show that any subvariety of Xr of codimension less than par must have degree a multiple of p. We also show that the bounds on the codimension in our results are strict by exhibiting subvarieties of the appropriate codimension whose degrees are

BACKGROUND AND OBJECTIVE The tracer tachnetium-99m-2-methoxy-isobutyl-isonitrile (Tc99m-sestaMIBI) has recently been shown to concentrate in some neoplastic tissues, including myeloma. We investigated the diagnostic capacity and limits of this procedure in tracing focal myeloma lesions, and compared them with those of conventional radiological procedures (Xr). DESIGN AND METHODS We studied 55...

In order to define the full set of B-splines required, eight additional knots 1; 2; 3; 4 and nþ4; nþ5; nþ6; nþ7 are inserted automatically by the routine. The first four of these are set equal to the smallest xr and the last four to the largest xr. The representation of sðxÞ in terms of B-splines is the most compact form possible in that only nþ 3 coefficients, in addition to the nþ 7 knots, fu...

AMract. A general spin model on the Cayley tree lattice, which includes both the q component Potts and the Ashkin-Teller models, is considered. The free energy in zero field is evaluated in a closed form and found to be analytic in temperature. The model exhibits no long-range order in the sense that the probability of finding two sites far away to be in spin states a and @ is a constant, indep...

The reaction dynamics of ground state boron atoms, B(Pj), with acetylene, was reinvestigated and combined with novel electronic structure calculations. Our study suggests that the boron atom adds to the carbon–carbon triple bond of the acetylene molecule to yield initially a cyclic intermediate undergoing two successive hydrogen atom migrations to form ultimately an intermediate i3. The latter ...

We study the analytic Bethe ansatz in solvable vertex models associated with the Yangian Y (Xr) or its quantum affine analogue Uq(X (1) r ) for Xr = Br, Cr and Dr. Eigenvalue formulas are proposed for the transfer matrices related to all the fundamental representations of Y (Xr). Under the Bethe ansatz equation, we explicitly prove that they are pole-free, a crucial property in the ansatz. Conj...

Mindfulness is considered an important factor of individual's subjective well-being. Consequently, Human-Computer Interaction (HCI) has investigated approaches that strengthen mindfulness, i.e., by inventing multimedia technologies to support mindfulness meditation. These often use smartphones, tablets, or consumer-grade desktop systems allow everyday usage in users' private lives the scope org...

Saccharomyces strains engineered to ferment xylose using Scheffersomyces stipitis xylose reductase (XR) and xylitol dehydrogenase (XDH) genes appear to be limited by metabolic imbalances, due to differing cofactor specificities of XR and XDH. The S. stipitis XR, which uses both NADH and NADPH, is hypothesized to reduce the cofactor imbalance, allowing xylose fermentation in this yeast. However,...

An x-ray specular reflectivity (XR) and off-specular diffuse scattering (XDS) study of the coupled thermal capillary fluctuations and the intrinsic profiles of two interacting fluid-fluid interfaces is presented. The measurements are carried out on complete wetting films of perfluoromethylcyclohexane (PFMC) on the surface of bulk liquid eicosane (C20), as a function of film thickness 30<D<160 A...

There is preclinical support for using NMDA receptor glutamatergic antagonists to aid in naltrexone-based treatment of opioid dependence. We hypothesized that adding memantine will improve efficacy of extended-release (XR) naltrexone to prevent relapse. In this double blind study opioid-dependent participants (N=82) underwent inpatient detoxification and naltrexone induction. During naltrexone ...
