The vulnerability of periphyton and grazers to current and future levels of ultraviolet radiation (UV) has important ramifications for energy flow in shallow waters. We reduced ambient UV levels in a Tennessee stream with UVopaque Plexiglas suspended over the stream and compared periphyton under these Plexiglas filters to periphyton under UV-transparent polyvinylidene film. The experiments were...

Results:  UV-C Technology effectively reduces environmental contamination and should be considered when environmental transmission is significant.  The Optimum UV TM device achieved an overall 3.56-log10 reduction for MRSA in 5 minutes and an overall 2.78-log10 reduction for C. difficile spores in 10 minutes in typical patient rooms (not treated with UV reflective wall coating).  When the pa...

We describe a free spinor field on a noncommutative sphere starting from a canonical realization of the algebra U(u(2|1)) and a sequence of su(2)-invariant embeddings of su(2) representations. The gauge extension of the model the Schwinger model on a noncommutative sphere is defined and the model is quantized. Due to the noncommutativity of the sphere, the model contains only a finite number of...

We review here the main direct or indirect ways to detect the possible presence of large amounts of cold molecular hydrogen in the outer parts of disk galaxies, an hypothesis that we have recently developed. Direct ways range from H2 absorption in the UV domain to detection of the radio hyperfine structure: the orthoH2 molecule has an hyperfine, or ultrafine, structure in its fundamental state,...

In this paper, we consider an application of distributed detection and fusion framework to utterance verification (UV) and confidence measure (CM) objectives. We formulate the UV as a distributed detection and Bayesian fusion problem by combining various individual UV methods. We essentially design an optimal fusion rule that achieves minimum error rate. In the relevant isolated word OOV reject...
