Major contributions in theoretical physics do not emerge in a vacuum. They usually are inspired by experiment, require near total immersion in the relevant theoretical and experimental literature, and are often preceded by years of preliminary work, including the publication of failed or incomplete attempts at producing a theory, while recognition of their success does not always come instantly...

Most NCAA football teams never play each other in a given season, which has made ranking them a long-running and much-debated problem. The official Bowl Championship Series (BCS) standings are determined in equal parts by input from coaches, sports writers, and an average of algorithmic rankings. These standing determine which teams play for the national championship, and, in part, which teams ...

New calculation reveals that E is constant in a thin layer across the Fermi surface, befitting the definition of energy gap parameter, ∆ varies dramatically. The BCS self-consistent equation has a simple and exact solution, showing that the well-known ratio 3.5 must be replaced by 4. A simple formula is found to estimate energy gap from first principles with reasonable accuracy, useful to the c...

We describe an approach for deening and making use of compositions of partial speciications written in diierent formal languages. The technique provides a rst step towards integrating formal methods that use the notations. We discuss the integration process and consider how reenement can occur in such a setting. We present several examples of formal heterogeneous speciications, and two examples...

We show how critical temperatures Tc from the BCS-Bose crossover theory (defined self-consistently by both the gap and fermion-number equations) requires unphysically large couplings for the Cooper/BCS model interaction to differ significantly from the Tc of ordinary BCS theory (where the number equation is replaced by the assumption that the chemical potential equals the Fermi energy). Further...

Percutaneous transluminal angioplasty using balloon catheters for Budd-Chiari syndrome (BCS) and transcatheter arterial chemoembolization (TACE) for unresectable hepatocellular carcinoma (HCC) have become increasingly accepted as alternative therapeutic modalities. However, few studies have investigated the clinical efficacy of combining percutaneous microwave ablation with angioplasty for pati...

A cross-sectional study was carried out to determine the knowledge and practices of 425 female secondary school teachers from 20 selected secondary schools in Selangor, Malaysia on breast cancer screening (BCS). A self-administered, structured questionnaire was used for data collection. This study showed moderate to low knowledge on breast cancer (BC) and BCS among teachers. Only 19%, 25% and 1...

Women’s limited knowledge about breast cancer screening (BCS), combined with differences in Eastern and Western disease prevention concepts, may contribute to late-stage breast cancer diagnosis among minorities. Children can be conduits of knowledge transfer to adults. This pilot study tested the use of a culturally-tailored theatrical preschool performance in increasing Chinese American women’...

CONTEXT AND OBJECTIVE Recently, breast-conserving surgery (BCS) has been replacing mastectomy for breast cancer treatment. The aim of this study was to evaluate the changes in mastectomy and BCS rates and the factors relating to these shifts. DESIGN AND SETTING A retrospective study in a Brazilian public hospital. METHODS Pathological records from female patients who underwent surgery for b...

A neural network system for boundary segmentation and surface representation, inspired by a new local-circuit model of visual processing in the cerebral cortex, is used to enhance images of range data gathered by a synthetic aperture radar (SAR) sensor. Boundary segmentation is accomplished by an improved Boundary Contour System (BCS) model which completes coherent boundaries that retain their ...
