Effects of transition metal substitutions on the incommensurability and spin fluctuations in BaFe2As2 by elastic and inelastic neutron scattering [PDF]

open access: yes, 2012
The spin fluctuation spectra from nonsuperconducting Cu-substituted, and superconducting Co-substituted, BaFe2As2 are compared quantitatively by inelastic neutron scattering measurements and are found to be indis- tinguishable.

Procedure for short-lived particle detection in the OPERA experiment and its application to charm decays [PDF]

open access: yes, 2014
The OPERA experiment, designed to perform the first observation of $\nu_\mu \rightarrow \nu_\tau$ oscillations in appearance mode through the detection of the $\tau$ leptons produced in $\nu_\tau$ charged current interactions, has collected data from ...

An exploratory study into the factors that influence patients' perceptions of cleanliness in an acute NHS trust hospital [PDF]

open access: yes, 2007
Purpose – If NHS hospitals wish to influence patients to choose them and, as the literature review suggests, cleanliness will be a key-influencing factor in making that choice, it would seem important for hospitals to understand what factors lead people ...

Object knowledge modulates colour appearance [PDF]

open access: yes, 2011
We investigated the memory colour effect for colour diagnostic artificial objects. Since knowledge about these objects and their colours has been learned in everyday life, these stimuli allow the investigation of the influence of acquired object ...
