The new Accutrak delivery system was associated with less deep prosthesis implantation in the left ventricular outflow tract, which could be related to the lower rate of permanent pacemaker requirement.

Dynamic exercise could be directly associated with the severity of the phenotype in relation to the precocity of major ventricular arrhythmic events and right ventricular systolic dysfunction in patients with high-risk definite ARVC/D.

Recent attempts to turn Standard Quantum Theory (SQT) into a coherent representational system show considerable improvement over previous offerings, but such attempts still fail to settle important questions about the nature of material systems, as current theorizing about the latter effectively resolves into a multiplicity of incompatible statements about their nature, physical systems and their representation. Specifically, the most cogent proposals land in effective empirical underdetermination and mutual empirical equivalence, reviving old anti−realist fears about quantum physics. In this paper such fears are discussed and found unsound. It is argued that nothing of global skeptical or agnostic significance really follows from the kind of underdetermination presently encountered in fundamental quantum theory. The case is instructive, however, for what it shows about the characteristics and prospects of scientific realism as a perspective in contemporary philosophy of science.

GRW models of the physical world are criticized in the literature for involving wave function “tails” that allegedly create fatal interpretive problems and even compromise standard arithmetic. I find such objections both unfair and misguided. But not all is well with the GRW approach. One complaint I articulate in this paper does not have to do with tails as such but with the specific way in which past physical structures linger forever in the total GRW wave function. By pushing the total proposal towards either the “Many Worlds” approach or the Bohmian approach, this feature diminishes extant GRW claims to preferability. I suggest, however, that the problem here is just an artifact of the particular and ultimately optional genre of collapse mechanism chosen by GRW.
