Perceived chronic stress influences the effect of acute stress on cognitive flexibility
Scientific Reports, 2021 Executive functions are cognitive processes that facilitate goal-directed behavior by enabling us to direct and control our thoughts. Cognitive flexibility is an executive function characterized by the ability to mentally shift between rules, strategies,

Low dimensional neutron moderators for enhanced source brightness [PDF]
, 2013 In a recent numerical optimization study we have found that liquid para-hydrogen coupled cold neutron moderators deliver 3 - 5 times higher cold neutron brightness at a spallation neutron source if they take the form of a flat, quasi 2-dimensional disc ...

Bi-spectral beam extraction in combination with a focusing feeder [PDF]
, 2013 Bi-spectral beam extraction combines neutrons from two different kind of moderators into one beamline, expanding the spectral range and thereby the utilization of an instrument. This idea can be realized by a mirror that reflects long wavelength neutrons

In-Beam Background Suppression Shield [PDF]
, 2015 The long (3ms) proton pulse of the European Spallation Source (ESS) gives rise to unique and potentially high backgrounds for the instrument suite. In such a source an instrument capabilities will be limited by it's Signal to Noise (S/N) ratio.

The effects of acclimation to moderate and acute cold in rats [PDF]
Acta Theriologica, 1978 Poczopko P., Jusiak R. & Tomaszewska L., 1978: The effects of acclimation to moderate and acute cold in rats. Acta theriol. 23, 13: 247—257 [With 1 Table & 5 Figs.]. In adult (300—400 g) male Wistar rats, acclimated for 3 weeks either to moderate (13 ± 1°C) or acute (5 ± 1°C) cold the changes of the metabolic rate in intact animals, respiration of ...

International Review of Social Psychology, 2018 Perceivers often view individuals described as “warm” to be generally positive and individuals described as “cold” to be generally negative. Consistent with the tenets of Construal Level Theory, McCarthy and Skowronski (2011) demonstrated this difference
