BACKGROUND A consensus definition for periprocedural myocardial infarction (MI) in coronary stent trials has not been established. Differences between a historic definition, based on modified World Health Organization (WHO) criteria, and a proposed universal definition have not been compared in a prospective clinical trial. METHODS AND RESULTS We randomly assigned 3687 patients with stable co...

We present a study of statistical relationships between SAR arc intensities acquired by the Paci®c Northwest Laboratory Photometer Network during 1978±1988 and solar and geomagnetic activity indices Dst; F 10:7, and Kp by use of the method of multiple regression analysis. We found signi®cant correlations between intensity and all of the indices involved. In the present work we show for the ®rst...

Arc-annotated sequences are useful for representing structural information of RNAs and have been extensively used for comparing RNA structures in both terms of sequence and structural similarities. Among the many paradigms referring to arc-annotated sequences and RNA structures comparison (see [2] for more details), the most important one is the general edit distance. The problem of computing a...

This paper studies the coordinated motion control of a hydraulic arm driven by single-rod hydraulic actuators (a scaled down version of an industrial backhoe/excavator arm). Compared to conventional robot manipulators driven by electrical motors, hydraulic arms have a richer nonlinear dynamics and strong couplings among various joints (or hydraulic cylinders). This paper presents a physical mod...

Pulsed dc power supplies provide enabling capability to dielectric reactive sputtering applications due to their ability to reduce or even eliminate arcing during the deposition process. As this technology matures there has been increasing interest in the semiconductor, optical and industrial coating industries to use pulsed-dc sputter supplies for difficult to deposit films. The fundamental be...

From Oligocene to Recent times a series of tectomcally controlled coastal embayments fonned on the Pacific fore-arc side of the southern Central American island-arc system. Each of these basins shows characteristic stratal geometries and facies distributIOns reflecting the complex interaction of changes of sea level. volcaniclastic input. and tectonic activity (subsidence, uplift). Sequential s...

By a well known theorem of Robbins, graph G has strongly connected orientation if and only is 2-edge-connected it easy to find, in linear time, either cut edge or strong G. A result Durand de Gevigney shows that for every k≥3 NP-hard decide given k-strong orientation. Thomassen showed one can check polynomial time whether 2-strong This implies digraph D we determine reorient (=reverse) some arc...

This study reports design an active radar calibrator (ARC) that produces equal spacing point target responses that serve as control points for both geometric and radiometric calibrations. The delay is digitally controlled implemented by FPGA. Specification and performance of the digital ARC were tested on C-band ERS-2 SAR image. From the experimental results, the FPGA circuit can produce one to...

Let M be an additive abelian group. An M-strong-oriented coloring of an oriented graph G is a mapping φ from V (G) to M such that φ(u) 6= φ(v) whenever −→uv is an arc in G and φ(v)−φ(u) 6= −(φ(t)−φ(z)) whenever −→uv and zt are two arcs in G. The strong oriented chromatic number of an oriented graph is the minimal order of a group M such that G has an M-strong-oriented coloring. This notion was ...
