A New Method for Connecting the Radiation Sources of Lightning Discharge Extension Channels

Earth and Space Science, 2021
The connections of lightning radiation sources along channels are greatly affected by the radiation source density, and the channel length is geometrically scaled when neglecting repeated discharges in the same channel.

Ecoefficiency Analysis and Regression in Data Conversion for Spiking Neural Network Training

Advanced Intelligent Systems, EarlyView.
The environmental footprint of spiking neural networks is quantified during dataset encoding and training for autonomous driving regression across three benchmarks. Temporal depth emerges as the dominant driver of energy consumption and CO2 emissions, while the accuracy–energy trade‐off proves dataset‐dependent. On conventional hardware, spiking models

Characterizing lightning NO_x production in the Ebro Valley with meteosat 12 LI and LMA observations [PDF]

Atmospheric Chemistry and Physics
Lightning is one of the main sources of NOx in the Earth's atmosphere, yet there is considerable variability in NOx production during thunderstorms. In this study, we combined optical lightning data from the Meteosat Third Generation (MTG) Lightning ...

Effects of oropharyngeal neuromuscular stimulation on the volumetric enlarged and reduced tongue base in minipigs

The Anatomical Record, EarlyView.
Abstract Hypoglossal nerve or tongue protruding muscle stimulation is a current treatment option for obstructive sleep apnea. Thus, the present study analyzed 3D deformations of the volumetric enlarged and reduced tongue base upon oropharyngeal neuromuscular stimulation.

Thunderstorm charge structures favouring cloud-to-ground lightning [PDF]

, 2021
Thunderstorm electrical structures favouring cloud-to-ground lightning were investigated through a Lightning Mapping Array (LMA), an accurate three-dimensional lightning location system that allows inferring the heights of the regions of charge.

Visualizing Specific Tubulin Isotypes and Pathogenic Variants in Cellular Microtubule Arrays

Cytoskeleton, EarlyView.
ABSTRACT Eukaryotic cells depend on dynamic microtubule arrays to execute a wide range of functions vital for life. These microtubule filaments are formed through the polymerization of α/β‐tubulin proteins, which can be generated from numerous tubulin genes, or isotypes.
