We present an updated measurement of the tau lifetime at SLD. 4316-pair events, selected from a 150k Z 0 data sample, are analyzed using three techniques: decay length, impact parameter, and impact parameter diierence methods. The measurement beneets from the small and stable interaction region at the SLC and the precision CCD pixel vertex detector of the SLD. The combined result is: = 288:1 6:...
Specific learning disorder (SLD) identification is arguably one of the most significant controversies in school psychology. One component this issue that guidelines and practices vary substantially across professionals states, which leads to inconsistent rates outcomes for students. To assess extent problem at district level, we surveyed special education administrators from 725 US districts re...
A measurement of the lifetime of the tau lepton has been made using a sample of 1671 Z 0 ! + , decays collected by the SLD detector at SLC. The measurement beneets from the small and stable collision region at SLC and the precision pixel vertex detector of SLD. Three analysis techniques have been used: decay length, impact parameter, and impact parameter diierence methods. The combined result i...
Introduction Microcirculatory alterations have been correlated with poorer outcomes in different populations of critically ill patients. A controlled increase in the local skin temperature (thermal challenge) induces vasodilation, which may represent a measure of microcirculation recruitability and can be easily evaluated non-invasively using skin laser Doppler (SLD) (1). We previously demonstr...
Based on a sample of approximately 500,000 hadronic Z 0 decays accumulated between 1993 and 1998, the SLD experiment has set limits on 24 fully charged two-body and quasi two-body exclusive charmless hadronic decays of B + , B 0 , and B 0 s mesons. The precise tracking capabilities of the SLD detector provided for the efficient reduction of combinatoric backgrounds, yielding the most precise av...
A new implementation of the surface Laplacian derivation (SLD) method is described which reconstructs a realistically shaped, local scalp surface geometry using measured electrode positions, generates a local spectral-interpolated potential distribution function, and estimates the surface Laplacian values through a local planar parametric space using a stable numerical method combining Taylor e...
Attention-deficit/hyperactivity disorder (ADHD) and specific learning disorders (SLDs) are an important cause of scholastic backwardness among children and often go unrecognized. Few studies have examined knowledge and attitudes toward ADHD and SLD among school-aged children. To address this deficit, 120 school-aged children, attending a child guidance clinic in Mumbai, were interviewed using a...
