Deference to the Plaintiff in Forum Non Conveniens Cases

This Note analyzes several cases in an effort to understand why, based on each case’s unique circumstances, the plaintiff’s choice of forum received a particular level of deference. This Note then produces a synthesized list of factors that alter the level of deference a plaintiff’s choice of forum receives under forum non conveniens analysis. An understanding of these factors provides increased predictability as to when a plaintiff’s choice of forum might receive heightened deference under this common law doctrine

Update on Partial-Wave Analysis

Partial-wave analysis is one step in a process connecting experimental measurements to the N* states we are studying. Progress has been made in the area of `model-independent' analysis. However, more model-dependent approaches are needed to cover broader energy ranges. An example of the problems faced by these more ambitious analyses is given.Comment: 6 pages.

Duration of heart failure and the risk of atrial fibrillation: different mechanisms at different times?

Chronic heart failure increases the risk of atrial fibrillation (AF), with the prevalence of AF paralleling the severity of heart failure.1 Factors that underlie this increased susceptibility to AF may include electrical, structural, and neurohumoral changes.2 In AF, it is recognized that atrial electrophysiological remodelling occurs and contributes to the perpetuation of the arrhythmia, most notably the decrease of effective refractory period (ERP) which predisposes to re-entry by shortening the wavelength. Does heart failure cause similar changes in atrial electrophysiology that predispose to the arrhythmia
