Background and study aims  For suspected pancreaticobiliary malignancies, endobiliary brush cytology during endoscopic retrograde cholangiopancreatography (ERCP) remains the diagnostic test of choice despite historically poor and variable sensitivity. This has led to increased use of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) as an initial test. Recently, our institution bega...

In this report, hierarchical self-organization of poly(tert-butyl acrylate) (PtBA) brushand mixed PtBA/ polystyrene (PS) brush-grafted silica nanoparticles (NPs) in PtBA-b-PS block copolymer and PtBA/PS polymer blend matrices having different molecular weights was investigated using transmission electron microscopy (TEM). Driven by the entropic interactions between the brushes and the polymer m...

Filtering Random Layering Effects for Imaging and Velocity Estimation

Data transport services are flourishing at the intra-domain level. Despite that, things look much worse when we try to cross a domain boundary. Operators are endlessly tuning Border Gateway Protocol (BGP) to achieve various traffic engineering goals [4], yet, unfortunately there is no easy way to allocate resources from point A to point B between two arbitrary domains on the Internet. Both work...

The American National Corpus and its annotations are represented in a stand-off XML format compliant with the specifications of ISO TC37 SC4 WG1’s Linguistic Annotation Framework. Because few systems that enable search and access of the corpus currently support stand-off markup, the project has developed a SAX like parser that generates ANC data with annotations in-line, in a variety of output ...
