High‐Voltage Stability of LiCoO2 Cathode Materials Composited With Vanadium‐Based Glass Coatings
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Vanadium‐based glasses show fluidity and good wettability toward other materials at low temperatures. The controlled precipitation of nanocrystals in vanadium‐based glasses enhances the material's mechanical properties and electrical conductivity. The VPFL coatings bond to the LiCoO2 interface via chemical bonds.

Auditory gamma‐band synchronization and attentional performance in juvenile myoclonic epilepsy
Epilepsia Open, EarlyView.Abstract Objective Cognitive difficulties in juvenile myoclonic epilepsy (JME) are part of the clinical phenotype alongside epileptic seizures; however, the underlying neurophysiological mechanisms remain unclear. Auditory steady‐state responses (ASSRs) to repetitive 40‐ and 80‐Hz stimuli are widely used measures of gamma‐band oscillations (GBOs ...

Adaptive Algorithm for Chirp-Rate Estimation
EURASIP Journal on Advances in Signal Processing, 2009 Chirp-rate, as a second derivative of signal phase, is an important feature of nonstationary signals in numerous applications such as radar, sonar, and communications. In this paper, an adaptive algorithm for the chirp-rate estimation is proposed.

Food Safety and Health, EarlyView.The gains from machine learning in nowcasting and forecasting food insecurity are still small and limited and cannot be observed in all countries. This review summarizes the public resources for data, corrects common misconceptions about model requirements, and establishes baseline requirements, explanations, causal inference, and equity in operational
