•Accessibility by non-experts: researchers in the social sciences should be able to use the system to share and explore data with no involvement from experts in data privacy, computer science, or statistics. •Generality: the system should be applicable and effective on a wide variety of heterogeneous datasets hosted in a repository such as the Harvard Dataverse. •Workflow-compatibility: the sys...

The Internet is changing rapidly the way people around the world communicate, learn, and work. Yet the tremendous benefits of the Internet are not shared equally by all. One way to close the gap of the ‘digital divide’ is to ensure Internet access to all schools from an early age. While both the USA and EU have embraced the promotion of Internet access to schools, the two have decided to financ...

In a study of g'(3684) radiative decays with the Mark II detector at SPEAR, we observe the decay sequence $' -+ rs,(2980), with the q,(2980) decaying into several completely reconstructed hadronic modes. We obtain a mass M = 298ok8 MeV/c2 and a width r < 40 MeV/c2 (gO$ confidence level), and present estimates of some of the decay branching ratios. Submitted to Physical Review Letters *This work...

This paper describes a robust multi-phase algorithm for marking of pitch pulses in speech using both glottal and speech signals. In the first phase, the glottal signal is used for the estimation of the fundamental frequency (f0) contour of the given sentence. Next, pitch mark candidates are generated on the basis of both glottal and speech signals. In the third phase, the best sequence of pitch...

This memo describes the results of Shack-Hartmann wavefront sensor measurements of the 48” mirror at the Whipple Observatory, Mount Hopkins, AZ. The observations show significant errors in the figure of the primary mirror. Visual inspection of the data shows spots that are significantly shifted, distorted in shape, and some spots that are missing entirely from the images. Local slope errors on ...
