Spatial Variability of Permafrost and Active Layer Thickness in a Forested Hillslope of the Taiga Shield

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Under continued climate warming, understanding present‐day permafrost distribution and the controls on ground thaw are critical for predicting permafrost thaw trajectories and associated implications. This study presents a high‐resolution investigation of permafrost extent and active layer thickness (ALT) across a coniferous forested hillslope

Compostable and Recyclable Baroplastic Triblock Copolymers Enable Low‐Energy Polymer Processing

Small, EarlyView.
Baroplastic Poly(L‐lactide)‐block‐poly(ethylene glycol)‐block‐poly(L‐lactide) triblock copolymers enable ambient‐temperature processing under moderate pressure, reducing energy demand while preserving polymer integrity. The materials show rapid industrial compostability, effective chemical and physical recyclability, and compatibility with heat ...

Research on Ultra‐Wideband Pulse Current Method for DC Partial Discharge Measurement

High Voltage, EarlyView.
ABSTRACT The conventional pulse current method is commonly used in AC or DC withstand voltage tests with partial discharge (PD) monitoring. Because of its relatively narrow measurement bandwidth, this method tends to ignore critical information in PD waveforms, making it difficult to eliminate pulse‐type interference under DC voltage conditions, where ...

Improvement of Mouse Spermatozoa Freezing at ‐80°C With Ascorbic Acid 2‐Glucoside at Thawing Phase

Andrology, EarlyView.
ABSTRACT Background Sperm cryopreservation is the most common method to maintain a great number of mutant mouse lines. However, the use of liquid nitrogen (LN2) for freezing presents considerable problems in terms of cost, safety, and accessibility. For this reason, the storage of semen samples at ‐80° in ultra‐freezers has been increasingly used in ...

Development of sleepiness in professional truck drivers: Real‐road testing for driver drowsiness and attention warning (DDAW) system evaluation

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary All new vehicle types within the European Union must now be equipped with a driver drowsiness and attention warning system starting from 2022. The specific requirements for the test procedure necessary for type approval are defined in the Annex of EU Regulation C/2021/2639.

A new approach to bandpass correction in spectrometer measurements using the Richardson-Lucy method

, 2013
Bandpass correction in spectrometer measurements using monochromators is often mandatory in order to obtain accurate measurement results. In this paper we propose a new approach based on the Richardson-Lucy method, which is an iterative deconvolution ...

Daily Predictors of Psychotic‐Like Experiences in Older Adults: The Role of Sleep Quality, Negative Emotions, and Cognitive Failures

Journal of Sleep Research, EarlyView.
ABSTRACT Psychotic‐like experiences are subclinical psychotic symptoms that are usually accompanied by sleep problems, negative emotions, and poorer cognitive functioning. However, their night‐to‐day associations remain understudied in older adults. 72 participants aged 50–79 took part in a home‐based sleep study.

An Electroencephalographic Study of Sleep Spindle and Infraslow Oscillation in Children With Autism Spectrum Disorder

Journal of Sleep Research, EarlyView.
ABSTRACT We investigated whether sleep microstructures show spatial differences in young children with autism compared with typically developing peers. 32‐channel electroencephalography (EEG) during natural sleep after 5–6 h of partial sleep deprivation was recorded from 53 children (26 with autism, 27 typically developing; 1.1–5.1 years).
