Monochromator-induced glitches m the extended X-ray absorption fine structure (EXAFS) are studied using a pinhole sample . We have collected more detailed beam-profile data that enabled us to do a better simulation of the glitch shape. Applying the model we developed earlier, we obtain excellent agreement between the simulation and the experimental pinhole glitch . We point out that the EXAFS g...

The purpose of this study was to chart the development of motor imagery ability between 5 and 29 years of age and its relationship to fine-motor skill. 237 participants performed a computerized Virtual Radial Fitts Task (VRFT) as a measure of Motor Imagery (MI) ability. Participants aimed at five targets, positioned along radial axes from a central target circle. The targets differed in width o...

Invasive weeds threaten the biodiversity and forage productivity of grasslands worldwide. However, management of these weeds is constrained by the practical difficulty of detecting small-scale infestations across large landscapes and by limits in understanding of landscape-scale invasion dynamics, including mechanisms that enable patches to expand, contract, or remain stable. While high-end hyp...

Both coarse-to-fine and A∗ parsing use simple grammars to guide search in complex ones. We compare the two approaches in a common, agenda-based framework, demonstrating the tradeoffs and relative strengths of each method. Overall, coarse-to-fine is much faster for moderate levels of search errors, but below a certain threshold A∗ is superior. In addition, we present the first experiments on hie...

here, we present a case of a 78-year-old man that underwent gastrointestinal endoscopy because of one- monthhistory of dysphagia to liquids and solid foods with accompanying weight loss. on endoscopy, there was distalesophageal stenosis. multiple biopsies were obtained. histologic examination of the samples revealed normaltissue. the stenosis was treated by dilatation and abdomino pelvic comput...

Subcutaneous tumor seeding after fine-needle percutaneous biopsy for hepatocellular carcinoma is a rarely seen complication. The authors describe a case of subcutaneous neoplastic seeding in a 70-year-old woman with chronic hepatitis C virus complicated by hepatocellular carcinoma. Ultrasonically guided fine-needle aspiration biopsy was performed in segment II of the liver. The neoplastic seedi...

BACKGROUND In the era of endobronchial/esophageal ultrasound (EBUS-TBNA/EUS-FNA), many centers forgo conventional transbronchial needle aspiration (C-TBNA) in favour of EBUS-TBNA/EUS-FNA despite no conclusive evidence showing better yields with EBUS-TBNA/EUS-FNA. OBJECTIVES Assess the feasibility of an algorithmic approach for mediastinal sampling beginning with C-TBNA utilizing rapid onsite ...

Mediastinal staging is generally performed by the use of imaging techniques such as CT (Computed Tomography) and PET (Positron Emission Tomography), mini-invasive techniques, as TBNA (Transbronchial Needle Aspiration), EBUS-TBNA (Ultrasound-Guided Transbronchial Needle Aspiration), EUS-FNA (Endoscopic Ultra Sound Fine-Needle Aspiration), and/or surgical techniques as mediastinoscopy, thoracosco...

CONTEXT Pancreatic and peripancreatic tuberculosis in immunocompetent patients is extremely rare. It often mimics pancreatic malignancy. Majority of the cases are diagnosed after an image guided biopsy or after an operation. CASE REPORT We report three cases of pancreatic tuberculosis in immunocompetent patients. All three cases were diagnosed without laparotomy. Diagnosis was made by contras...
