This paper is concerned with the relationship between the discount rate and the nature of long-run behavior in dynamic optimization models. The theory is developed under two conditions. The first is history independence, which rules out multiple limit sets. The second is a condition that avoids the reversion to a stable steady state, as the discount factor is lowered, once cycles have emerged. ...

The partition function of the O(n) loop model on the honeycomb lattice is mapped to that of the O(n) loop model on the 3-12 lattice. Both models share the same operator content and thus critical exponents. The critical points are related via a simple transformation of variables. When n = 0 this gives the recently found exact value μ = 1.711 041 . . . for the connective constant of self-avoiding...

Making decisions to undergo Autism Spectrum Disorders (ASD) genetic testing can be challenging. It is important to understand how the perceptions of affected individuals might influence testing decision-making. Although evidence has shown that psychological factors are important in predicting testing decisions, affect-type variables have been largely ignored among well-established health theori...

We present here the analysis of ultraviolet spectra from IUE and an X-ray spectrum from ROSAT PSPC observations of the X-ray weak, far-infrared loud AGN, PG 1126−041 (Mrk 1298). The first UV spectra taken in June 1992, simultaneously with ROSAT, show strong absorption lines of NV, CIV and SiIV, extending over a velocity range from −1000 to −5000 km s with respect to the corresponding line centr...

Nuclear medicine, technetium 99m renogram (DTPA) is the primary investigation for perfusion defects post-transplantation. It is accurate (up to 99% sensitivity), but time consuming, expensive and has the innate risks of an examination using ionising radiation. Contrast enhanced ultrasound (CEUS) is an emerging technology which may solve these issues, giving greater resolution and temporal infor...
