The Beginnings The seeds of the project began to germinate in late 1990 and early 1991 with our effort to rapidly prototype large-scale shared-memory multiprocessors. Because other research groups had a oneto two-year lead in their prototyping efforts—and considerably more resources—our project started with the goal of exploiting the parallel computers that our department was acquiring with fun...

Background: Children are believed to be more likely to be reported for maltreatment while they are working with mental health or social service professionals. This "surveillance bias" has been claimed to inflate reporting by fifty percent or more, and has been used to explain why interventions such as home visiting fail to reduce official maltreatment reporting rates. Methods: We use national c...

The technique of Harmonic Motion Imaging (HMI) utilizes the localized stimulus of the oscillatory ultrasonic radiation force as produced by two overlapping beams of distinct frequencies, and estimates the resulting harmonic displacement in the tissue in order to assess its underlying mechanical properties. In this paper, we studied the relationship between the measured displacement and the gel/...

Faraday rotation measurements are used to constrain simple models representing possible extremes of the structure of extra-galactic magnetic fields (EGMFs). Relevant fields are found quite generally to be at the μG level rather than the nG level usually assumed. Even the highest energy cosmic ray protons should experience large deflections over distances of order 1 Mpc. Such large deflections a...
