An extensive set of experimental measurements on the dynamics of the H(+) + D(2) and D(+) + H(2) ion-molecule reactions is compared with the results of quantum mechanical (QM), quasiclassical trajectory (QCT), and statistical quasiclassical trajectory (SQCT) calculations. The dynamical observables considered include specific rate coefficients as a function of the translational energy, E(T), the...

this article considers the many developments in technology and practice that are making libraries more connected and interdependent. it looks at new integrated online services and reviews the increasing importance of both formal and informal standards. global centralized web services are discussed. the relationships between information industry companies and libraries are considered. virtual re...

A novel signal modeling technique is described to compute smoothed time-frequency features for encoding speech information. These time-frequency features compactly and accurately model phonetic information, while accounting for the main effects of contextual variations. These segment-level features are computed such that more emphasis is given to the center of the segment and less to the end re...
