Recently, both the learning effect scheduling and re-entrant scheduling have received more attention separately in research community. However, the learning effect concept has not been introduced into re-entrant scheduling in the environment setting. To fill this research gap, we investigate re-entrant permutation flowshop scheduling with a position-based learning effect to minimize the total c...

Objective—To assess the eYcacy and safety of intravenous dofetilide in preventing induction of atrioventricular re-entrant tachycardia. Design—A multicentre, open, dose ranging trial. Fifty one patients with electrically inducible atrioventricular re-entrant tachycardia were allocated to one of five doses of dofetilide (1.5, 3, 6, 9, and 15 μg/kg), two thirds of the dofetilide dose being given ...

OBJECTIVES This study was designed to separate focal from atypical macro-re-entrant atrial tachycardia (AT) on the electrocardiogram (ECG). BACKGROUND Focal AT often cannot be distinguished from macro-re-entrant AT until the time of electrophysiology study (EPS). We hypothesized that quantitative ECG metrics should separate focal AT, using its short activation relative to tachycardia cycle le...

We apply the Nyquist method to the Hamiltonian mean field (HMF) model in order to settle the linear dynamical stability of a spatially homogeneous distribution function with respect to the Vlasov equation. We consider the case of Maxwell (isothermal) and Tsallis (polytropic) distributions and show that the system is stable above a critical kinetic temperature Tc and unstable below it. Then, we ...

We are interested in object-oriented programming methodologies that enable static verification of object-invariants. Reasoning soundly and effectively about the consistency of objects is still one of the main stumbling blocks to pushing object-oriented program verification into the mainstream. In this paper we explore a simple model of invariants that is intuitive and allows us to divide the ve...
