BACKGROUND A reliable and accurate estimation of liver size by physical examination is an important aspect of the clinical assessment of a patient. The scratch test uses auscultation to detect the lower liver edge by using the difference in sound transmission through the abdominal cavity over solid and hollow organs. The test is thought to be particularly useful if the abdomen is tense, distend...

Taking a structuration perspective while integrating reciprocity research in economics, this study examines the dynamics of reciprocal interactions in social Q&A communities. We postulate that individual users of social Q&A constantly adjust their kindness into the direction of the observed benefit and effort of others. Collective reciprocity emerges from this pattern of conditional strategy of...

Unsupervised joint alignment of images has been demonstrated to improve performance on recognition tasks such as face verification. Such alignment reduces undesired variability due to factors such as pose, while only requiring weak supervision in the form of poorly aligned examples. However, prior work on unsupervised alignment of complex, real-world images has required the careful selection of...

Currently, obesity has become one of the major health concerns in the United States. A way to relieve this problem is creating fitness activities using the technology and tools available at hand. “Punching Pad” is a prototype that utilizes Scratch for Arduino software and the Arduino Board to make this possible. This device is not only considered a viable fitness activity, but also it could hel...

This paper describes different Scratch activities proposed in different learning situations: for primary school-children aged about 9-10 years old; for in-service teachers active in various levels and types of schools, but with very low or without computing competences; for teachers and pupils in middle schools; for students in their beginning two years of technical secondary school (not necess...

Kullingia is considered a key taxon in demonstrating the presence of terminal Proterozoic–early Cambrian chondrophorine hydrozoans. However, Kullingia concentrica from the Lower Cambrian of northern Sweden possesses several features that show that it is not a body fossil but that it was formed by current or wave-induced rotation of an anchored tubular organism, possibly a sabelliditid. A scratc...

Background and objectives: Luteolin (3′,4′,5,7-tetrahydroxy flavone) is one of the most common flavones, which is naturally found in several edible plants and traditional medicine. It is known as a non-toxic compound with anti-inflammatory, antinociceptive, anticarcinogenic, antimutagenic, and antiangiogenic properties. Luteolin has antiproliferative activity against different ...

BACKGROUND AND PURPOSE MR imaging characteristics of optic neuropathy caused by cat scratch disease have not yet been described; this lack of information may result in incorrect diagnosis and may contribute to initiation of inappropriate therapy. Our study was based on the hypothesis that cat scratch disease-related optic neuropathy has distinct MR imaging features compared with those of other ...
