The in vitro activity of DX-619, a new des-F(6)-quinolone, was tested against staphylococci and compared to those of other antimicrobials. DX-619 had the lowest MIC ranges/MIC(50)s/MIC(90)s (microg/ml) against 131 Staphylococcus aureus strains (</=0.002 to 2.0/0.06/0.5) and 128 coagulase-negative staphylococci (0.004 to 0.25/0.016/0.125). Among strains tested, 76 S. aureus strains and 51 coagul...

The spin-dependent structure functions g 1 (x), g 2 (x), g W W 2 (x) and ¯ g 2 (x) and their moments are studied in the CM bag model. The results show that (i) 1 0 g 2 (x)dx = 0, i.e. the Burkhardt-Cottingham sum rule holds, hence g 2 (x) must have at least one non-trivial zero besides x = 0 and x = 1. 1 0 x 2 g 2 (x)dx is negative for the proton, neutron and deuteron. (iii) 1 0 x 2 g 2 (x)dx i...

We prove several weighted inequalities involving the Hilbert transform of a function f (x) and its derivative. One of those inequalities, − ∫ fx(x)[Hf (x)−Hf (0)] |x|α dx Cα ∫ (f (x)− f (0))2 |x|1+α dx, is used to show finite time blow-up for a transport equation with nonlocal velocity. © 2006 Elsevier Masson SAS.

A 56-year-old man underwent a single lead Lumax 640 DX implantable cardioverter defibrillator implantation for primary prevention of sudden cardiac death. A DX system consists of a single lead, which provides atrial as well as ventricular electrograms, and enhances atrial arrhythmia detection. Three months after the implantation, high-frequency episodes were detected on the far field and the at...

singular. Under the assumption that Imq(x) ≤ 0 for all x ∈ [a, b), Sims proved that for λ ∈ C+, there exists at least one solution of (1. 1) which lies in the weighted space L(a, b; Im[λ− q]dx); such a solution lies in L(a, b). There are now three distinct possibilities for λ ∈ C+: (I) there is, up to constant multiples, precisely one solution of (1. 1) in L(a, b; Im[λ−q]dx) and L(a, b), (II) o...

Sturm oscillation theorem for second order differential equations was generalized to systems and higher order equations with positive leading coefficient by several authors. What we propose here is a Sturm theorem for indefinite systems with Dirichlet boundary conditions of the form p2m du dx + p2m−2(x) du dx + · · ·+ p1(x) du dx + p0(x)u = 0, where pi is a smooth path of matrices on the comple...

We study an inverse problem for a non-compact Riemannian manifold whose ends have the following properties : On each end, the Riemannian metric is assumed to be a short-range perturbation of the metric of the form (dy) + h(x, dx), h(x, dx) being the metric of some compact manifold of codimension 1. Moreover one end is exactly cylindrical, i.e. the metric is equal to (dy) +h(x, dx). Given two su...

In this paper we study a particular multidimensional deconvolution problem. The distribution of the noise is assumed to be of the form G(dx) = (1− α)δ(dx) + αg(x)dx, where δ is the Dirac mass at 0 ∈ Rd, g : Rd → [0,∞) is a density and α ∈ [0, 1 2 [. We propose a new minimax estimation procedure, which is not based on a Fourier approach, but on a fixed point method. The performances of the proce...

Docker is undeniably powerful and revolutionary in how containerized system development developed today, but it apparent that the learning curve for should be addressed, as typically complex at times, especially beginners. One of fundamental tasks a workflow Dockerfile configurations, which times require ample time to study observe attaining best practices, even appropriate result. This issue a...
