Observation of the Dsj(2463) and Confirmation of the Dsj*(2317)
Using 13.5 inverse-femtobarns of e+e- annihilation data in the CLEO II
detector at CESR, we have observed a new narrow state decaying to Ds*+ pio,
denoted the DsJ(2463). A possible interpretation holds that this is a J^P = 1+^
partner to the DsJ*(2317) state recently discovered by the BaBar Collaboration
which is consistent with J^P = 0^+. We have also confirmed the existence of the
DsJ*(2317) in its decay to Ds+ pio. We have measured the masses of both states,
accounting for the cross-feed background that the two states represent for each
other, and have searched for other decay channels for both states. No narrow
resonances are seen in neutral or doubly charged Ds pi modes.Comment: Presented at MRST 2003 conference, "Joefest" Syracuse University, May

Non-Molecular-Clock-Like Evolution following Viral Origins in Homo sapiens
Researchers routinely adopt molecular clock assumptions in conducting sequence analyses to estimate dates for viral origins in humans. We used computational methods to examine the extent to which this practice can result in inaccurate ‘retrodiction.’ Failing to account for dynamic molecular evolution can affect greatly estimating index case dates, resulting in an overestimated age for the SARS-CoV-human infection, for instance
