CrAs was observed to possess the bulk superconductivity under high-pressure conditions. To understand the superconducting mechanism and explore the correlation between the structure and superconductivity, the high-pressure structural evolution of CrAs was investigated using the angle-dispersive X-ray diffraction (XRD) method. The structure of CrAs remains stable up to 1.8 GPa, whereas the latti...

BACKGROUND Cardiorenal anemia syndrome (CRAS) is an evolving global epidemic associated with increased morbimortality and cost of care. The management of patients with CRAS remains a challenging undertaking worldwide and the lack of evidence-based clinical guidelines adds to the challenge. We aimed to explore the prevalence and survival rates of heart failure patients with CRAS in Tanzania. M...

We propose an alternative market design to the current credit ratings industrial organization. An issuer delegates a pass-through non-monitoring trust to acquire ratings from credit ratings agencies (CRAs). The trust pays outcome contingent fees, such that truth-telling is incentive compatible for CRAs, eliminating ratings inflation. Moreover, because the trust acts as an intermediary, it elimi...

Neoplastic tissue exhibits high glucose utilization and over-expression of glucose transporters (GLUTs) and hexokinases (HKs), which can be imaged by (18)F-Fluorodeoxyglucose-positron emission tomography (FDG-PET). The aim of the present study was to investigate the expression of glycolysis-associated genes and to compare this with FDG-PET imaging as well as with the cellular proliferation inde...

Using oligonucleotide-mediated 'loop-in' mutagenesis strategies in M13, a heat-inducible ubiquitin (Ub) gene was extended by sequences coding for the C-terminal 11 amino acids of Ha-RAS. The resulting gene was transformed into AR13 and production of the Ub-peptide extension was induced by heat treatment. After one-step purification, the fusion protein (Ub-cRAS) was used as a substrate for farne...

Current alphanumeric and biometric authentication systems cannot withstand situations where a user is coerced into releasing their authentication materials under hostile circumstances. Existing approaches of coercion resistant authentication systems (CRAS) propose authentication factors such as implicit learning tasks, which are non-transferable, but still have the drawback that an attacker can...

Contact relation algebras (CRAs), introduced in Düntsch et al. (1999), arise from the study of “part–of” and “contact” relations rooted in mereology and have applications, for example, in qualitative spatial reasoning. We give an overview of the origins of CRAs and numerous examples.

Credit rating agencies (CRAs) very often have been criticized for announcing inaccurate credit ratings and are suspected of being exposed to con‡icts of interest. Despite these objections CRAs remained largely unregulated. Based on Pagano & Immordino (2007), we study the optimal regulation of CRAs in a model where rating quality is unobservable and enforcing regulation is costly. The model show...

The collapse of so many AAA-rated structured ...nance products in 2007-2008 has brought renewed attention to the causes of ratings failures and the con‡icts of interest in the Credit Ratings Industry. We provide a model of competition among Credit Ratings Agencies (CRAs) in which there are three possible sources of con‡icts: 1) the CRA con‡ict of interest of understating credit risk to attract ...
