Microbial metabolism in wormcast affected the perturbation on soil organic matter by microplastics under decabromodiphenyl ethane stress.

Large-scale plastic wastes annually inevitably induce co-pollution of microplastics (MPs) and novel brominated flame retardants (NBFRs), while gaps remain concerning their effect on terrestrial function. We investigated the impact of polylactic acid (PLA) or polyethylene (PE) MPs after aging in soil-earthworm microcosms under decabromodiphenyl ethane (DBDPE) contamination. MPs altered the food (i.

Optimal vocal therapy for respiratory muscle activation in patients with COPD: effects of loudness, pitch, and vowels.

Background: Vocal therapy, such as singing training, is an increasingly popular pulmonary rehabilitation program that has improved respiratory muscle status in patients with chronic obstructive pulmonary disease (COPD). However, variations in singing treatment protocols have led to inconsistent clinical outcomes.

Objective: This study aims to explore the content of vocalization training for patients with COPD by observing differences in respiratory muscle activation across different vocalization tasks.

LWheatNet: a lightweight convolutional neural network with mixed attention mechanism for wheat seed classification.

Introduction: With the advent of technologies such as deep learning in agriculture, a novel approach to classifying wheat seed varieties has emerged. However, some existing deep learning models encounter challenges, including long processing times, high computational demands, and low classification accuracy when analyzing wheat seed images, which can hinder their ability to meet real-time requirements.

Methods: To address these challenges, we propose a lightweight wheat seed classification model called LWheatNet.
