We consider collaborative tagging systems where users can attach tags to information objects. Such systems are widely used to add keywords meta-data to photos, videos, or web pages (social bookmarking applications). The meta-data is then used by information retrieval mechanism to provide accurate query answers. To that end, the goal of collaborative tagging systems is to quickly discover the tr...

ShapeSift is a framework for supporting sustainabilitybased decision making during selection of similar previous designs from part repositories. Our framework is designed for 3D part repositories that contain metadata pertaining to materials and manufacturing processes as well as the functionality of a given part. To demonstrate the usefulness of the proposed framework we develop an example mul...

OBJECTIVE The mechanisms whereby birth asphyxia leads to generation of seizures remain unidentified. To study the possible role of brain pH changes, we used a rodent model that mimics the alterations in systemic CO(2) and O(2) levels during and after intrapartum birth asphyxia. METHODS Neonatal rat pups were exposed for 1 hour to hypercapnia (20% CO(2) in the inhaled gas), hypoxia (9% O(2)), ...

It is argued that there are at least two alleles at the achondroplasia locus: one responsible for classic achondroplasia and one responsible for hypochondroplasia. Homozygosity for the achondroplasia gene produces a lethal skeletal dysplasia; homozygosity for hypochondroplasia has not been described. We report here a child considered to be a genetic compound for the achondroplasia and hypochond...

A change in the type of lesion produced by the fibroma virus has been observed. At about its 18th serial transfer in domestic rabbits the virus lost its ability to induce fibromas when administered subcutaneously. Instead, lesions developing in either the subcutaneous tissue or in the testicle were predominantly inflammatory in character and partly composed of lymphocytes and large mononuclear ...
