Rankin Inlet PolarDARN radar observations of duskward moving Sun-aligned optical forms [PDF]

Annales Geophysicae, 2008
On 15 February 2007, several duskward moving sun-aligned (SA) auroral forms have been observed by the all-sky camera at Resolute Bay, Nunavut (Canada). Concurrent observations with the Rankin Inlet (RANK) PolarDARN HF radar within the field-of-view of

Exceptionally strong summer-like zonal wind reversal in the upper mesosphere during winter 2015/16 [PDF]

Annales Geophysicae, 2017
The 2015/16 Northern Hemisphere winter season was marked by peculiarities in the circulation pattern in the high-latitude mesopause region. Wind measurements from the Andenes (69° N, 13° E) meteor radar show westward winds below 84 km and eastward ...

Cortical responses elicited by luminance and compound stimuli modulated by pseudo-random sequences: comparison between normal trichromats and congenital red-green color blinds

Frontiers in Psychology, 2015
Pattern-reversal visual evoked cortical potential (VECP) shows positivity for luminance and chromatic equiluminant stimuli while pattern-onset VECP shows positivity for luminance pattern-onset and negativity for chromatic pattern-onset.

Relationship between first-twitch depression and train-of-four ratio during sugammadex reversal of rocuronium-induced neuromuscular blockade [PDF]

Korean Journal of Anesthesiology, 2016
BackgroundThe primary outcome of sugammadex reversal for rocuronium-induced neuromuscular block (NMB) is a train-of-four ratio (TOFR) of 0.9, not first twitch (T1) height.

Nanoscopic Filters as the Origin of d Wave Energy Gaps [PDF]

, 2003
A ferroelastic nanoscopic checkerboard pattern of pseudo- and superconductive gaps has been resolved by scanning tunneling microscopy on BSCCO. Using this pattern one can derive [not assume] a macroscopic anisotropic d wave superconductive energy gap ...

Key Role of Arctic Sea‐Ice in Subseasonal Reversal of Early and Late Winter PM2.5 Concentration Anomalies Over the North China Plain

Geophysical Research Letters, 2023
The PM2.5 (fine particulate matter with diameter ≤2.5 μm) concentration anomalies over the North China Plain (NCP) in early and late winter sometimes show a subseasonal reversal, which brings a great challenge for precise control of air pollution, and ...

Behavioral pattern separation and cognitive flexibility are enhanced in a mouse model of increased lateral entorhinal cortex-dentate gyrus circuit activity

Frontiers in Behavioral Neuroscience, 2023
Behavioral pattern separation and cognitive flexibility are essential cognitive abilities that are disrupted in many brain disorders. A better understanding of the neural circuitry involved in these abilities will open paths to treatment.

Genetic deletion of α7 nAChRs reduces hippocampal granule and pyramidal cell number in both sexes but impairs pattern separation in males only

Frontiers in Neuroscience, 2023
IntroductionNeurogenesis within the dentate gyrus is thought to play an important role in cognitive processes such as reversal learning and pattern separation.
