Automatic adaptation of content for mobile devices is a challenging problem because optimal adaptation often depends on the usage semantics of content, as well as the context of users (e.g., screen size of device being used, network connectivity, location, etc.). Usage-awaRe Interactive Content Adaptation (URICA) is an automatic technique that adapts(More)
Small form factor mobile devices have been widely used to provide ubiquitous access to the web content. However, due to screen size limitations, it is inconvenient to browse most of the websites that are traditionally designed for desktop PCs. Therefore, developing automatic adaptation techniques to render and squeeze web content into small mobile devices(More)
Pigmented villonodular synovitis (PVNS) is an uncommon benign proliferative disorder of synovium that may involve joints, tendon sheaths, and bursae. It most often affects the knees, and less frequently involves other joints. It presents in the temporomandibular joints (TMJs) extremely rarely. The authors report an elderly female patient with PVNS of the(More)
Mobile devices are increasingly being used to access Web content but lack the resources for proper presentation to the user. To address this problem, content is typically adapted to be more suitable for a mobile environment. Community-driven adaptation (CDA) is a novel approach to automatic content adaptation for mobile devices that adapts content based on(More)
Usage-awaRe Interactive Content Adaptation (URICA) is an automatic technique that adapts content for display on mobile devices based on usage semantics. URICA allows users who are unsatisfied with the system's adaptation decision to take control of the adaptation process and make changes until the content is suitably adapted for their purposes. The(More)

Visual Cryptography Scheme (VCS) is an encryption method that uses combinatorial techniques to encode secret written materials. The idea is to convert the written material into an image and encode this image into n shadow images. The decoding only requires only selecting some subset of these n images, making transparencies of them, and stacking them on top(More)
Arteannuin B (I) was converted to hydroxy lactones (VII, VIII) by a mixture of formic acid and sulfuric acid. Compound VI and Compound VII both showed activity against leukemia P 388 cell in vitro. The rate of growth inhibition were 97.5% and 11.8% for (VI) and 80% and 52.6% for (VII) at the concentration of 10 and 1 micrograms/ml respectively. It seems(More)
"Subspinosin" isolated from the root of Damnacanthus subspinosus Hand-Mazz (Rubiaceae) and deduced as 3-ethoxymethyl-2-hydroxy-1-methoxyan-thraquinone 1 by Li et al in 1981, should be corrected as 2-ethoxymethyl-3-hydroxy-1-methoxyanthraquinone 5 by comparison with the synthetic compound. Since 5 is already known as damnacanthol-omega-ethyl ether, the name(More)
