Modelling the U.S. sovereign credit rating [PDF]
Journal of Banking & Finance, 2014 This paper proposes a new methodology for generating sovereign credit ratings. These are determined by mapping the probability that the debt-GDP ratio might exceed a maximum debt limit at some point in the future into a credit rating. The debt limit can be either ad hoc or based on the financial ability of a government to change fiscal policy in the ...

Advanced Materials, EarlyView.Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

Crystal Engineering of Reticular Materials for Gas‐ and Liquid‐Phase Hydrocarbon Separation
Advanced Materials, EarlyView.Crystal engineering enables systematic study of structure/function relationships as exemplified by pore engineering of reticular sorbents, including porous coordination networks and covalent organic frameworks. This review assesses such studies applied across the full scope of industrially relevant hydrocarbon separations to provide insight into how ...

Sovereign Credit Ratings Methodology: An Evaluation
IMF Working Papers, 2002 This paper describes and evaluates the sovereign credit ratings methodologies of Standard & Poor's, Moody's Investors Service, and Fitch Ratings. A simple definition of ratings failure-based on ratings stability-is proposed and tested, pointing to falling failure rates, consistent upside bias, and strong interagency correlation.

Perspective on Aqueous Batteries: Historical Milestones and Modern Revival
Advanced Materials, EarlyView.This review retraces the development of aqueous batteries from classical Zn‐MnO2 chemistry to modern Zn and Ni systems, correlating voltage, capacity, and electrolyte formulation with practical performance. By mapping historical success and failure onto current and future research directions, it identifies guiding principles that steer the design of ...

A Mussel‐Inspired Bioadhesive Patch to Selectively Kill Glioblastoma Cells
Advanced Science, EarlyView.An innovative mussel‐inspired bioadhesive patch has been developed for post‐surgical glioblastoma treatment. The patch, which adheres strongly in biological environments, releases a localized treatment. This treatment, acting via reactive oxygen species, shows specific toxicity to glioblastoma cells.

Adult Sex Ratio as a Demographic Feedback Linking Mating Systems, Parental Care, and Evolution
Advanced Science, EarlyView.Breeding systems are some of the most diverse social behavior, and our team is investigation the evolutionary causes of this diversity. This review summarises our research carried out at the University of Bath. We argue that demographic components of wild populations, especially the adult sex ratio, plays a key role driving breeding system variation ...
