The incidence and severity of infections in childhood is typically greater in males. The basis for these observed sex differences is not well understood, and potentially may facilitate novel approaches to reducing disease from a range of conditions. We here investigated sex differences in HIV-infected children in relation to antiretroviral therapy (ART)(More)

(2) The VERITAS Collaboration–see S.P.Wakely's paper " The VERITAS Prototype " from these proceedings for affiliations Abstract In recent years, blazar surveys at radio and X-ray energies have greatly increased our understanding of this type of active galaxy. The combination of multi-wavelength data has shown that blazars follow a well defined sequence in(More)
(2) The VERITAS Collaboration–see S.P.Wakely's paper " The VERITAS Prototype " from these proceedings for affiliations Abstract Mrk 421 is the first TeV blazar found to exhibit significant spectral variability during strong flaring activity, showing hardening of the TeV spectrum in high emission states. Mrk 421 is also known to exhibit flux variability on(More)
(2) The VERITAS Collaboration–see S.P.Wakely's paper " The VERITAS Prototype " from these proceedings for affiliations Abstract Strong flares of TeV gamma-ray emission up to a level of ∼ 5 Crab were detected by the Whipple 10 m atmospherič Cerenkov telescope from the BL Lac-ertae object 1ES1959+650 during May-July 2002. We report here the results of follow(More)
