Comparison between indices during geomagnetic disturbances [PDF]
Geofísica Internacional, 2004 Auroral indices AE, AU, AL, and Troshichev index from Thule, PC (Polar Cap) are compared for geomagnetic disturbances of different intensities. To identify perturbations, the indices Dst and AE have been used. Fourteen storms have been analyzed, with Dst

InfoScience, EarlyView.This study integrates a wrist‐worn sensing platform based on a low‐noise planar Hall magnetoresistive sensor with time‐series deep learning to enable long‐range, single‐sensor, multi‐command gesture recognition with high accuracy. Further evaluations show reliable generalization across different days, previously unseen users, wearing‐position ...

HIGH-SPEED SOLAR WIND AND GEOMAGNETIC ACTIVITY
Radio Physics and Radio Astronomy, 2015 The impact of high-speed solar wind disturbances on the occurrence of geomagnetic storms is analyzed. The solar wind velocity values, determined from scintillation observations at the UTR-2 and URAN-2 Ukrainian decameter radio telescopes are analyzed ...

White light reduces flight height of birds in low‐density migration corridor
The Journal of Wildlife Management, EarlyView.We conducted an experiment to better understand the effects of artificial light at night treatments of varying spectral power distributions on in‐flight migratory bird behavior as measured by a portable radar. Broad‐spectrum white light emissions reduced avian flight height as compared to dark periods and more than other light treatments.

Integrative Zoology, EarlyView.The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...
