Center-surround antagonistic receptive field (CSARF) organization is the basic synaptic circuit that serves as elementary building blocks for spatial information processing in the visual system. Cells with such receptive fields converge into higher-order visual neurons to form more complex receptive fields. Retinal bipolar cells (BCs) are the first neurons along the visual pathway that exhibit ...

BACKGROUND/AIMS The diagnosis of an underlying myeloproliferative neoplasm (MPN) is often problematic in patients with Budd Chiari syndrome (BCS) or portal vein thrombosis (PVT). This study aimed to assess the diagnostic value of the JAK2 gene V617F gain-of-function mutation for MPN in splanchnic vein thrombosis patients. MATERIALS AND METHODS One hundred eleven patients (80 with PVT, 27 with...

Familial occurrence of Budd-Chiari syndrome (BCS) has been reported in scattered cases, which potentially favors the congenital theory. A review of the literature was conducted to demonstrate this phenomenon in China. PubMed, VIP, and CNKI databases were searched for studies describing at least two Chinese BCS patients from the same one family. In the 18 eligible papers, 30 siblings or first-de...

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...
