Heisenberg Limit Superradiant Superresolving Metrology [PDF]

open access: yes, 2014
We propose a superradiant metrology technique to achieve the Heisenberg limit super-resolving displacement measurement by encoding multiple light momenta into a three-level atomic ensemble.

Serum Levels of Neuropeptides in Cows with Left Abomasal Displacement [PDF]

open access: yesVeterinary Sciences, 2018
Abomasal displacement (AD) to the left is a common disease in high-yielding dairy cows after parturition. In view of the previously reported changes in tissue neuropeptide concentrations in cows with AD, the primary aim of this study was to evaluate the effect of AD and breed on serum neuropeptide concentrations.

Voxel-wise motion artifacts in population-level whole-brain connectivity analysis of resting-state FMRI. [PDF]

open access: yesPLoS ONE, 2014
Functional Magnetic Resonance Imaging (fMRI) based brain connectivity analysis maps the functional networks of the brain by estimating the degree of synchronous neuronal activity between brain regions. Recent studies have demonstrated that "resting-state"

Picometer level displacement metrology with digitally enhanced heterodyne interferometry

open access: yesOptics Express, 2009
Digitally enhanced heterodyne interferometry is a laser metrology technique employing pseudo-random codes phase modulated onto an optical carrier. We present the first characterization of the technique's displacement sensitivity. The displacement of an optical cavity was measured using digitally enhanced heterodyne interferometry and compared to a ...

Energy level displacement of excited np states of kaonic hydrogen

open access: yes, 2005
We compute the energy level displacement of the excited np states of kaonic hydrogen within the quantum field theoretic and relativistic covariant model of strong low-energy bar-KN interactions suggested in EPJA21, 11 (2004).

Horses’ (Equus caballus) Ability to Solve Visible but Not Invisible Displacement Tasks Is Associated With Frustration Behavior and Heart Rate

open access: yesFrontiers in Behavioral Neuroscience, 2021
Many frameworks have assessed the ultimate and ontogenetic underpinnings in the development of object permanence, but less is known about whether individual characteristics, such as sex or training level, as well as proximate factors, such as arousal or ...
