Measurement of the neutron beta-asymmetry parameter A(0) with ultracold neutrons
(American Physical Society, 2012-11-12)
We present a detailed report of a measurement of the neutron beta-asymmetry parameter A(0), the parity-violating angular correlation between the neutron spin and the decay electron momentum, performed with polarized ultracold ...

Male Carriers of the FMR1 Premutation Show Altered Hippocampal-Prefrontal Function During Memory Encoding
(Frontiers Media S.A., 2012-10-30)
Previous functional MRI (fMRI) studies have shown that fragile X mental retardation 1 (FMR1) premutation allele carriers (FXPCs) exhibit decreased hippocampal activation during a recall task and lower inferior frontal ...
a population of z > 2 far-infrared herschel-spire-selected starbursts
(IOP Publishing Ltd., 2012-12)
We present spectroscopic observations for a sample of 36 Herschel-Spire 250-500 mu m selected galaxies (HSGs) at 2 < z < 5 from the Herschel Multi-tiered Extragalactic Survey. Redshifts are confirmed as part of a large ...
a 10 kpc scale seyfert galaxy outflow: hst/cos observations of iras f22456-5125
(IOP Publishing Ltd., 2012-06)
We present analysis of the UV spectrum of the low-z AGN IRAS F22456-5125 obtained with the Cosmic Origins Spectrograph on board the Hubble Space Telescope. The spectrum reveals six main kinematic components, spanning a ...
Storage and export of organic matter in a headwater stream: responses to long-term detrital manipulations
(Ecological Society of America, 2012-09)
Riparian habitats provide organic matter inputs that influence stream biota and ecosystem processes in forested watersheds. Over a 13-yr period, we examined the effects of litter exclusion, small- and large-wood removal, ...
Mechanisms of change in psychosocial interventions for autism spectrum disorders.
Research into psychosocial interventions (particularly cognitive-behavior therapies and social skills training) for social-communication deficits among individuals with autism spectrum disorder (ASD) has proliferated over ...
Multiwavelength campaign on Mrk 509 VIII. Location of the X-ray absorber
(EDP Sciences, 2012-03)
Aims. More than half of all active galactic nuclei show strong photoionised outflows. A major uncertainty in models for these outflows is the distance of the gas to the central black hole. We use the results of a massive ...
Multiwavelength campaign on Mrk 509 X. Lower limit on the distance of the absorber from HST COS and STIS spectroscopy
(EDP Sciences, 2012-08)
Aims. Active galactic nuclei (AGN) often show evidence of photoionized outflows. A major uncertainty in models for these outflows is the distance (R) to the gas from the central black hole. In this paper we use the HST/COS ...
