In an attempt to illuminate some of the underlying causes of phonological deficit in dyslexia we investigated the influences of processing suprasegmental acoustic features on children’s phonological awareness and reading and spelling abilities. In the English cohort tested (N=65) the processing of duration but not of intensity in 9-year old dyslexic children was significantly poorer than in age...

The current profile along the 126 ns, multi-bunch beam pulse in the Next Linear Collider Test Accelerator (NLCTA) is monitored with fast toroids (rise time -1 ns). Inserted at several positions along the beam line, they allow us to track current transmission as a function of position along the bunch train. Various measurements, such as rise time, current, width, and slope, are made on the digit...

The Mantle Electromagnetic and Tomography (MELT ) Experiment was designed to distinguish between competing models of magma generation beneath mid-ocean ridges. Seismological observations demonstrate that basaltic melt is present beneath the East Pacific Rise spreading center in a broad region several hundred kilometers across and extending to depths greater than 100 kilometers, not just in a na...

The overall objective of our work is to understand bubble growth and rise in natural marine sediments. In the first phase of our study (to mid-2003) we demonstrated that bubbles grow and rise in sediments by the mechanism of fracture. The second (current) phase has aimed to develop methods to measure the mechanical parameters that control the fracture of soft sediment; these parameters, i.e., Y...

The Rise in the U.S. Dollar The value of the dollar has climbed steadily over much of the past two years (Chart 1). The dollar’s rise through August 1998 represents more than a 20 percent appreciation over its average value in the 1991-95 period and more than a 30 percent strengthening relative to its unusually weak performance in April 1995. This large appreciation is reminiscent of the apprec...

As early as the mid–19th century, physicians had noted that patients with kidney disease and those with long-term high blood pressure (hypertension) both had enlarged heart muscles. The first clue to this kidney–hypertension connection came from physiologists Robert Tigerstedt and Per Bergman who injected kidney extracts into rabbits, thus triggering a dramatic rise in blood pressure. In a prop...
