Background and Aims Little is known about the outcomes of endoscopic resection (ER) for patients with colorectal adenomas (CRAs) high-grade dysplasia (HGD) or intramucosal cancer (IMCA). This study aimed to estimate rate local/malignant recurrence, identify predictive factors local recurrence (LR), evaluate treatment after ER HGD/IMCA. Methods A retrospective review was performed who underwent ...

During the recent credit crisis credit rating agencies (CRAs) became increasingly lax in their rating of structured products, yet increasingly stringent in their rating of corporate bonds. We examine a model in which a CRA operates in both the market for structured products and for corporate debt, and shares a common reputation across the two markets. We find that, as a CRA’s reputation becomes...

Correlation effects on the electronic structure of half-metallic CrAs in zinc-blende structure are studied for different substrate lattice constants. Depending on the substrate the spectral weight of the non-quasiparticle states might be tuned from a well developed value in the case of InAs substrate to an almost negligible contribution for the GaAs one. A piezoelectric material that would allo...

This paper presents the design and implementation of a simple continuous media storage server: CRAS on Real-Time Mach. CRAS is a specially optimized storage system for retrieving multiple continuous media streams such as audio and video from a disk at constant rates for small scale distributed multimedia systems. Many previous continuous media storage servers have focussed on high throughput fo...
