BACKGROUND In vivo description of ventricular tachycardia (VT) circuits is limited by insufficient spatiotemporal resolution. We used a novel high-resolution mapping technology to characterize the electrophysiological properties of the postinfarction reentrant VT circuit. METHODS In 15 swine, myocardial infarction was induced by left anterior descending artery balloon occlusion. Animals were ...

We consider empirical risk minimization of linear predictors with convex loss functions. Such problems can be reformulated as convex-concave saddle point problems, and thus are well suitable for primal-dual first-order algorithms. However, primal-dual algorithms often require explicit strongly convex regularization in order to obtain fast linear convergence, and the required dual proximal mappi...

The purpose of this study was to determine whether delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) and T2 mapping are accurate techniques for measuring cartilage thickness in the metacarpus3/metatarsus3 (Mc3/Mt3) of Thoroughbred racehorses. Twenty-four Mc3/Mt3 cadaver specimens were acquired from six healthy racehorses. Cartilage thickness was measured from postint...

In this paper, we introduce a modified Ishikawa-type proximal point algorithm for approximating common solution of minimization problem, monotone inclusion problem and fixed problem. We obtain strong convergence the proposed to finite family asymptotically demicontractive mapping in Hadamard spaces. Numerical example is given illustrate applicability our main result. Our results complement exte...

Digital soil mapping (DSM) approaches provide information by utilising the relationship between properties and environmental variables. Calibration of DSM models requires measurements that may often have substantial measurement errors which propagate to outputs need be accounted for. This study applied a geostatistical-based approach incorporates error variances in covariance structure spatial ...
