The two-particle momentum correlation function of a K^{-}p pair from high-energy nuclear collisions is evaluated in the K[over ¯]N-πΣ-πΛ coupled-channel framework. The effects of all coupled channels together with the Coulomb potential and the threshold energy difference between K^{-}p and K[over ¯]^{0}n are treated completely for the first time. Realistic potentials based on the chiral SU(3) dynamics are used which fit the available scattering data.

Because no specific treatment or vaccine is available for MAYV infection, we capitalized on an IRES-based approach to develop a live-attenuated MAYV vaccine candidate. Testing in infant, immunocompetent as well as interferon receptor-deficient mice demonstrated a high degree of attenuation, strong induction of neutralizing antibodies, and efficacy against lethal challenge.

First, we evaluated the neutralizing antibody response, measured by plaque reduction neutralization (PRNT(80)), and clinical response of the two viruses in groups of four ewes each. The virus dose was 1×10(5)plaque forming units (PFU).

Communities are exploring ways to increase transportation coordination to improve access for seniors. One such effort is a brokered transportation system in which one agency serves as the central point of contact for ride information or actually arranging transportation for clients of multiple programs by use of a combination of transportation services. A team of social work faculty and students from the University of New Hampshire (UNH) Social Work Outreach Center, a center that provides service learning opportunities to students, collaborated with a local coalition to investigate the specific transportation needs of the region's senior citizens.
