Non-rapid eye movement sleep with low muscle tone as a marker of rapid eye movement sleep regulation

BMC Neuroscience, 2006
Background It was recently reported that epochs of non-REM sleep (NREMS) with low muscle tone represent a partial correlate of REM sleep (REMS). To further investigate this phenomenon, episodes of restricted night-time sleep (23:00 – 03.00h) and ...

Correspondence of the sign change in organic magnetoresistance with the onset of bipolar charge transport

Applied Physics Letters, 2008
In this work we examine the transition between positive and negative organic magnetoresistance in poly[2-methoxy-5-(3′, 7′-dimethyloctyloxy)-p-phenylenevinylene] in order to understand how different regimes of charge transport affect the organic magnetoresistance effect. To characterize the charge transport in these devices we measured the current, low

Statistical study of the substorm onset: its dependence on solar wind parameters and solar illumination [PDF]

Annales Geophysicae, 2005
Based on 1829 well-defined substorm onsets in the Northern Hemisphere, observed during a 2-year period by the FUV Imager on board the IMAGE spacecraft, a statistical study is performed. From the combination of solar wind parameter observations by ACE and

Impact of rainfall onset date on crops yield in Ghana

Frontiers in Sustainable Food Systems, 2023
Rainfall onset date (ROD) influences farmer planting decisions, yet there is a dearth of information on the extent to which ROD influences crop yield. This study assesses the effect of ROD on the yield of four crops (Maize, millet, rice, and sorghum) in ...

Chemotherapy for Spinal Cord Intramedullary Pediatric Low‐Grade Glioma—A Systematic Literature Review

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric intramedullary low‐grade gliomas (PIMLGGs) are rare neoplasms that present unique clinical and management challenges. Although surgery remains the primary tool for tissue diagnosis and decompression, complete gross‐total resection is frequently unfeasible due to the infiltrative nature of these lesions.

Correspondence of Consonant Clustering with Particular Vowels in German Dialects

Languages
Recent work found a correspondence between consonant clustering probability in monosyllabic lexemes and the three vowel types, short and long monophthong and diphthong, in German dialects. Furthermore, that correspondence was found to be bound to a North–

Resolving Seasonal Ice Velocity of 45 Greenlandic Glaciers With Very High Temporal Details

Geophysical Research Letters, 2019
Seasonal glacier ice velocities are important for understanding controlling mechanisms of ice flow. For many Greenlandic glaciers, however, these measurements are limited by low temporal resolution.
