Advanced Science, EarlyView.This work explores the process of morning awakening of the human brain using polysomnography paired with simultaneous stereo‐electroencephalography, a method that provides high spatial and temporal resolution for examining brain activity. Awakening is characterized by an increase in high‐frequency spectral power and connectivity.

HR2875: Spectroscopic discovery of the first B star + white dwarf binary [PDF]
, 1998 We report the discovery, in an Extreme Ultraviolet Explorer (EUVE) short wavelength spectrum, of an unresolved hot white dwarf companion to the 5th-magnitude B5Vp star HR2875. This is the first time that a non-interacting white dwarf$+$ B star binary has been discovered; previously, the the earliest type star known with a white dwarf companion was ...

The Astronomical Journal, 2023 Excess infrared flux from white dwarf stars is likely to arise from a dusty debris disk or a cool companion. In this work, we present near-infrared spectroscopic observations with Keck/MOSFIRE, Gemini/GNIRS, and Gemini/Flamingos-2 of seven white dwarfs ...

Advanced Science, EarlyView.How do chemical and physical processes involving multiple phases develop on compact astrophysical objects such as white dwarf stars? Herein, entropy‐driven self‐assembly of rod‐shaped nanoparticles in centrifugal acceleration fields up to 7251 times the gravity of Earth is investigated, where strong acceleration fields accelerated the kinetics of phase

Automatic flower detection and phenology monitoring using time‐lapse cameras and deep learning
Remote Sensing in Ecology and Conservation, Volume 8, Issue 6, Page 765-777, December 2022., 2022 We present an automatized method for monitoring flower phenology of specific plant species trough full growing seasons and across geographical regions. The method couples image‐based monitoring of field plots with a dedicated convolutional neural network to detect and count flowers in the images, and returns information on flowering phenology at ...

Absolute Proper Motions to B~22.5: IV. Faint, Low Velocity White Dwarfs and the White Dwarf Population Density Law [PDF]
, 2001 The reduced proper motion diagram (RPMD) for a complete sample of faint stars with high accuracy proper motions in the North Galactic Pole field SA57 is investigated. Eight stars with very large reduced proper motions are identified as faint white dwarf candidates.

Advanced Science, EarlyView.Lignin and hemicellulose are used to develop agricultural adjuvants to decrease agrochemical run‐off from foliage, by suppressing droplet rebound and enhancing adhesion of aqueous solutions on plant leaves. The wood components combine surface activity with surface pinning effects and to improve by tenfold the droplet rebound in citrus leaves ...
