Identification of a characteristic morphology of a coronary stenosis likely to result in myocardial infarction would facilitate the prospective evaluation of infarct prevention strategies and identification of high-risk patients. We postulated that coronary lesions associated with recent myocardial infarction or unstable angina would have an angiographic morphology suggesting disruption of an a...

Let M be a metric space and let 4>(M) = M be a homeomorphism. 0(m) = X^d^w) is called the orW of m^M under «2> • ■ • (»i<m2...

Let (X,L) be a polarised manifold. We show that K-stability and asymptotic Chow stability of the blowup of X along a 0-dimensional cycle are closely related to Chow stability of the cycle itself, for polarizations making the exceptional divisors small. This can be used to give (almost) a converse to the results of Arezzo and Pacard in [1], [2], and to give new examples of Kähler classes with no...

BACKGROUND Little information exists regarding the prognostic role of biomarkers of inflammation in Mediterranean patients. High C-reactive protein and neopterin levels - a marker of macrophage activation - predict cardiovascular events in stable angina patients and patients with acute coronary syndromes (ACS). We sought to assess whether plasma neopterin levels predict adverse clinical outcome...

INTRODUCTION There is continuing controversy surrounding force production and stability of muscle contraction on the descending limb of the force-length (F-L) relation. Many believe that force production on the descending limb is unstable. This notion is correct if the negative slope of the F-L relationship, which is obtained in a series of static, independent contractions, would also be negati...

The complex Ginzburg–Landau (CGL) equation on a one-dimensional domain with periodic boundary conditions has a number of different symmetries, and solutions of the equation may or may not be fixed by the action of these symmetries. We investigate the stability of chaotic solutions that are spatially periodic with period L with respect to subharmonic perturbations that have a spatial period kL f...

We consider generalized flame balls which correspond to stationary spherical flames with a flow of hot inert gas, either a source or a sink, at the origin. Depending on the flow, these flames can have positive, zero, or negative burning speeds, with zero speeds characterizing the Zeldovich flame balls. A full analytical description of these structures and their stability to radial perturbations...

The asymptotic attractors of a nonlinear dynamical system play a key role in the long-term physically observable behaviors of the system. The study of attractors and the search for distinct types of attractor have been a central task in nonlinear dynamics. In smooth dynamical systems, an attractor is often enclosed completely in its basin of attraction with a finite distance from the basin boun...
