3 Pascucci, ValerioConforming Morse-Smale complexesMorse-Smale (MS) complexes have been gaining popularity as a tool for feature-driven data analysis and visualization. However, the quality of their geometric embedding and the sole dependence on the input scalar field data can limit their applicability when expressing application-dependent features....2014-01-01
4 DeTar, CarletonFirst determination of the strange and light quark masses from full lattice QCDWe compute the strange quark mass ms and the average of the u and d quark masses mˆ using full lattice QCD with three dynamical quarks combined with the experimental values for the rr and K masses.

15 Regehr, JohnSome guidelines for proportional share CPU scheduling in general-purpose operating systemsOur premise is that since there already exists a large, mature body of literature on real-time scheduling in general-purpose operating systems, it is time to spend more effort deciding which of these algorithms should be used and when, and less effort on generating new algorithms. In this paper we f...2001-01-01
