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...

In this paper the qualitative dynamic behavior of reaction kinetic models of G protein signaling is examined. A simplified basic G protein signaling structure is defined, which is extended to be able to take the effect of slow transmission, RGS mediated feedback regulation and ERK-phosphatase mediated feedback regulation into account. The resulting model gives rise to an acceptable qualitative ...

Mark Goresky t Andrew Klappex a A b s t r a c t A new class of feedback register, based on ramified extensions of the 2-adic numbers, is described. An algebraic framework for the analysis of these re~ters and the sequences they output is given. TilLs framework parallels that of linear feedback shift resistere. As one consequence of this, a method for cracking summation ciphers is given. These r...

New data on clouds and moisture, made possible by reanalysis of weather satellite observations, show that the atmosphere reacts to warm ocean pools in the Western Pacific Ocean with increased moisture and cloudiness~ suggesting a negative feedback limiting the rise in seasurface temperature. The reverse was observed over hot deserts where both moisture and cloudiness decrease, suggesting a posi...

Recent research has shown that control of the oxygen content in the catalyst has potential to further reduce the emissions from spark ignited engines. This gives rise to a cascade structure where an outer loop influences an inner loop. Different ways of augmenting the inner loop, a traditional PI-feedback controller based on feedback from the binary oxygen sensor, are studied. The SI-engine con...

At present the Frascati Φ-factory DAΦNE is operating in multibunch regime with stored currents in the range of 0.5-1 A in both e+ and erings. A longitudinal bunch-bybunch feedback system has been operating in each DAΦNE main ring since the beginning of the machine commissioning. The transverse bunch-by-bunch feedback system working in the vertical plane has been implemented last year in both ri...

Primary cultures of purified human cytotrophoblasts have been used to examine the expression of the corticotropin-releasing hormone (CRH) gene in placenta. We report here that glucocorticoids stimulate placental CRH synthesis and secretion in primary cultures of human placenta. This stimulation is in contrast to the glucocorticoid suppression of CRH expression in hypothalamus. The positive regu...
