Recent work suggests that an autosomal dominant gene for schizophrenia may be located on the 5q11-q13 region of chromosome 5 (refs 1 and 2): a report of schizophrenia associated with trisomy 5q11-q13 in two members of a family of Chinese origin prompted the discovery of linkage with markers p105-599Ha and p105-153Ra in five Icelandic and two English(More)
The Thomson scattering (TS) diagnostics set [Rev.] has been upgraded to deliver measurements of electron temperature (T e) and density (n e) with improved temporal and spatial resolution. Two 30 Hz, 1.3 J Nd-doped yttrium aluminum garnet (Nd:YAG) lasers share a vertical beam path through the tokamak plasma and are fired in alternating fashion, allowing(More)
An improved energy confinement regime, I-mode is studied in Alcator C-Mod, a compact high-field divertor tokamak using Ion Cyclotron Range of Frequencies (ICRF) auxiliary heating. I-mode features an edge energy transport barrier without an accompanying particle barrier, leading to several performance benefits. H-mode energy confinement is obtained without(More)

BACKGROUND Adherence to cardioprotective medications in the year after acute coronary syndrome hospitalization is generally poor and is associated with increased risk of rehospitalization and mortality. Few interventions have specifically targeted this high-risk patient population to improve medication adherence. We hypothesize that a multifaceted(More)
High resolution measurements on the Alcator C-Mod tokamak [I.H. Hutchinson et al, of the transport barrier in the " Enhanced D α " (EDA) regime, which has increased particle transport without large edge localized modes, show steep density and temperature gradients over a region of 2-5 mm, with peak pressure gradients up to 12 MPa/m. Evolution of the(More)
In a cross-sectional survey of 226 HIV-infected men, we examined the occurrence of diarrhoea and its relationship to drinking water consumption patterns, risk behaviours, immune status and medication use. Diarrhoea was reported by 47% of the respondents. Neither drinking boiled nor filtered water was significantly associated with diarrhoea (OR = 0.5 [0.2,(More)
At modest 3 He levels (n 3He /n e ~ 8-12%), in relatively low density D(3 He) plasmas, e n ≤ 1.3×10 20 m-3 , heated with 50 MHz rf power at B t0 ~ 5.1 T, strong (up to 90 km/s) toroidal rotation (V φ) in the co-current direction has been observed by high-resolution x-ray spectroscopy on Alcator C-Mod. The change of central V φ scales with the applied rf(More)
The time evolution of toroidal rotation velocity profiles has been measured in Alcator C-Mod [I.mas using a tangentially viewing x-ray spectrometer array. The strong co-current toroidal rotation in enhanced D α (EDA) high confinement mode (H-mode) plasmas is observed to propagate in from the edge on a time scale similar to the energy confinement time. The(More)
