Pollution Across Chinese Provinces [PDF]

open access: yes
We revisit the environmental Kuznets curve (EKC) hypothesis using 1987-1995 data for Chinese provinces. A comparison of off-sample (1996-2004) predictions to actual emissions indicates that more stringent rules are still needed to fight industrial (waste

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Generation and diffusion characteristics of CO during excavation blasting in underground upward-inclination roadways: Based on field measurements and CFD simulations

open access: yesCase Studies in Thermal Engineering
Carbon monoxide (CO) generation during roadway blasting in underground mines poses a serious threat to the health and safety of workers. The generation and diffusion characteristics of CO during and after blasting must be better understood for its ...

A wireless-communication-based measurement of gas pressure with capsule-slime sealing device

open access: yesInternational Journal of Mining Science and Technology, 2019
To solve the existing problems of imperfect sealing and the inaccurate measurement of gas pressure in traditional sealing, the present study builds a new model of capsule-slime sealing device based on wireless pressure gauge.

Quantitative proteomic analysis reveals different characteristics of bladder cancer cells after exposure to bisphenol A

open access: yesFEBS Open Bio, EarlyView.
Bisphenol A (BPA), a common chemical in plastics, exerts dual effects on bladder cancer cells: low doses promote growth and migration, while high doses suppress growth and migration. Multi‐omics and bioinformatics reveal BPA acts via MAPK and inflammatory pathways.

Unraveling the Molecular Mechanisms of Glioma Recurrence: A Study Integrating Single‐Cell and Spatial Transcriptomics

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Glioma recurrence severely impacts patient prognosis, with current treatments showing limited efficacy. Traditional methods struggle to analyze recurrence mechanisms due to challenges in assessing tumor heterogeneity, spatial dynamics, and gene networks.

Patch Plate Materials Compatibility Assessment [PDF]

open access: yes
Lunar dust proved to be a greater problem during the Apollo missions than was originally anticipated. The highly angular, charged dust particles stuck to seals, radiators, and visors; clogged mechanisms; and abraded space suits.
