A strong revitalization of the field of high temperature superconductivity (HTSC) has been induced recently by the discovery of T(C) around 26 K in F-doped LaFeAsO iron pnictides. Starting from this discovery, a huge amount of experimental data have been accumulated. This important corpus of results will allow the development of suitable theoretical models aimed at describing the basic electron...

The electrochemical double layer plays a critical role in electrochemical processes. Whilst there have been many theoretical models predicting structural and electrical organization of the electrochemical double layer, the experimental verification of these models has been challenging due to the limitations of available experimental techniques. The induced potential drop in the electrolyte has ...

In this paper we analyse and discuss the HR Diagram position of two extra-solar planet-host stars HD37124 and HD46375 by means of theoretical stellar evolution models. This work was triggered by the results obtained by Laws et al. (2003) who found that these stars were in contradiction to the expectation based on their high metallicity. Fixing the age of both stars with the value based on their...

During protein folding in which few, if any, definable kinetic intermediates are observable, the nature of the transition state is central to understanding the course of the reaction. Current experimental data does not distinguish the relative contributions of side chain immobilization and dehydration phenomena to the major rate-limiting transition state whereas this distinction is central to t...

This paper compares systematically the two theoretical models of adaptation, ecological and evolutionary. Using notions from innovation, learning, and balanced change, the two models are contrasted in the context of 73 European, Japanese, and U.S. industrial robotics firms that introduced new robotics products in 1984-1997. A hybrid of ecological and evolutionary views is found to predict innov...

Past theoretical models suggest fishing disease-impacted stocks can reduce parasite transmission, but this is a good management strategy only when the exploitation required to reduce transmission does not overfish the stock. We applied this concept to a red abalone fishery so impacted by an infectious disease (withering syndrome) that stock densities plummeted and managers closed the fishery. I...

Magnetically tunable scattering resonances have been used with great success for precise control of s-wave scattering lengths in ultracold atomic collisions. We describe relatively simple yet quite powerful analytic treatments of such resonances based on the analytic properties of the van der Waals long range potential. This theory can be used to characterize a number of properties of specific ...

Evidence-based policy-making has been a much-debated concept. This paper builds on various insights for a novel perspective: policy-driven, narrative-based evidence gathering. In a case study of UK priority setting for bioenergy innovation, documents and interviews were analysed to identify links between diagnoses of the problem, societal visions, policy narratives and evidence gathering. This ...

The degree to which spatial patterns influence the dynamics and distribution of populations is a central question in ecology. This question is even more pressing in the context of rapid habitat loss and fragmentation, which threaten global biodiversity. However, the relative influence of habitat loss and landscape fragmentation, the spatial patterning of remaining habitat, remains unclear. If l...
