Pulsed-field ablation (PFA) is an emerging modality for pulmonary vein isolation. There limited data on the effect of different field strengths PFA in achieving durable cavotricuspid isthmus block. This study examines safety and efficacy three CTI In this study, eleven healthy swine (mean weight= 36.6 ± 3.8 kg) underwent a followed up minimum 12 weeks. An 8-French, 6-electrode purpose-designed ...

Monodisperse PFA and carbon hollow microspheres have been prepared without templates in a single synthesis process by a microfluidic methodology.

Pulsed-field ablation (PFA) is an emerging non-thermal tissue-selective ablative technology that can be used for pulmonary vein isolation (PVI). A single pulse of PFA result in reversible electroporation. The field strength and the number applications required to transform electroporation into irreversible require further investigation. This study evaluates effect strengths on acute PVI. An 8-F...

Optimum reactive power dispatch (ORPD) significantly impacts the operation and control of electrical systems (EPS) due to its undeniable benefit in economic reliability systems. ORPD is a sub-problem optimal flow (OPF). The main aim reduce/minimize real loss. Among swarm intelligence (SI) metaheuristic algorithms particle optimization (PSO), which has fast convergence speed gives optimum soluti...

We prove that all maps on N∗ that are exactly two to one, are trivial if PFA is assumed.

A performance analysis of likelihood ratio test (LRT)-based and generalized likelihood ratio test (GLRT)based array receivers for the detection of a known real-valued signal corrupted by a potentially noncircular interference is considered in this paper. The distribution of the decision statistics associated with the LRT and GLRT is studied. This allows us to give exact closed-form expressions ...

We consider various decision problems for probabilistic finite automata (PFA)s with isolated cut-points. Recall that a cut-point x is said to be isolated for a PFA if the acceptance probability of all finite strings is bounded away from x. First we establish the exact level of undecidability of the problem of determining if a cut-point is isolated; we show this problem to be Σ2-complete. Next w...

Measurement of the Antiplatelet Effects of Aspirin in Cerebrovascular Disease To the Editor: We read with interest the recent article on the use of the PFA-100 in measuring the ex vivo response to aspirin therapy in patients with cerebrovascular disease.1 Most patients were assessed in the acute phase after ischemic stroke or transient ischemic attack, although some patients with asymptomatic s...

The Platelet Function Analyzer (PFA-100) was used to measure platelet function in paediatric patients with destructive versus underproduction thrombocytopenia. Closure time (CT) and total volume (TV) measurements with standard 150 microm apertures discriminated between patients with similar platelet counts from 30 to 150 x 10(9)/l. However, at platelet counts < 30 x 10(9)/l, a 100-microm apertu...
