Geospatial and econometric approaches or older driver safety: Analysis of crash injury severity of regional highways.

PLoS One

January 2025

State Key Laboratory of Automotive Safety and Energy, School of Vehicle and Mobility, Tsinghua University, Beijing, China.

This study tried to focus on the older drivers' group and explore the impact factors of injury severity involving older drivers from geo-spatial analysis. To reach the goal, a spatial analysis was proposed employing geographic information systems (GIS) with a case study application to two counties in Nevada. First, crash clusters were explored using Density-Based Spatial Clustering of Applications with Noise (DBSCAN) approach to investigate the spatial crash pattern for older drivers, and determine high risk locations of injury severity.

Article Synopsis
  • Widespread PET microplastics in wastewater treatment plants impact nitrous oxide (NO) turnover, affecting production and consumption processes.
  • The study assesses the effects of two sizes of PET MPs (0.1 mm and 0.5 mm) on NO dynamics in aerobic granular sludge systems, revealing that 0.1 mm PET MPs significantly inhibit denitrification processes.
  • Results show that 0.1 mm PET MPs promote NO production by disrupting microbial activities and electron transfer, ultimately reducing the system's NO-sink capability and hindering efforts toward carbon neutrality.

This study evaluates three Machine Learning (ML) models-Temporal Kolmogorov-Arnold Networks (TKAN), Long Short-Term Memory (LSTM), and Temporal Convolutional Networks (TCN)-focusing on their capabilities to improve prediction accuracy and efficiency in streamflow forecasting. We adopt a data-centric approach, utilizing large, validated datasets to train the models, and apply SHapley Additive exPlanations (SHAP) to enhance the interpretability and reliability of the ML models. The results show that TKAN outperforms LSTM but slightly lags behind TCN in streamflow forecasting.

Woven Cement Slurry.

Adv Mater

January 2025

College of Civil Engineering and Architecture, Zhejiang University, Hangzhou, 310058, China.

Weaving, a pivotal technique in human construction activities since the Neolithic era, remains unattainable in modern concrete construction. Here, a novel particle-polymer coalescence strategy is proposed, which involves electrostatic, bridging, coordinating, and hydrogen bonding interactions, to establish balanced particle cohesion, enabling the fabrication of stretchable cement slurry. The bending, knotting, coiling, winding, and interlacing of cement filaments for structural textiles is successfully realized beyond traditional formwork casting, grouting, and 3D-printing, and fabricate the first-ever Chinese knot woven with cement.

January 2025

Erasmus School of Law and Erasmus School of Health Policy & Management, Erasmus University Rotterdam, Rotterdam, The Netherlands.

Who should decide what passes for disinformation in a liberal democracy? During the COVID-19 pandemic, a committee set up by the Dutch Ministry of Health was actively blocking disinformation. The committee comprised civil servants, communication experts, public health experts, and representatives of commercial online platforms such as Facebook, Twitter, and LinkedIn. To a large extent, vaccine hesitancy was attributed to disinformation, defined as misinformation (or data misinterpreted) with harmful intent.

Irrigation rapidly expanded during the 20 century, affecting climate via water, energy, and biogeochemical changes. Previous assessments of these effects predominantly relied on a single Earth System Model, and therefore suffered from structural model uncertainties. Here we quantify the impacts of historical irrigation expansion on climate by analysing simulation results from six Earth system models participating in the Irrigation Model Intercomparison Project (IRRMIP).

Crucial role of subsurface ocean variability in tropical cyclone genesis.

Nat Commun

January 2025

Department of Atmospheric and Oceanic Science, University of Maryland, College Park, MD, USA.

The upper ocean provides thermal energy to tropical cyclones. However, the impacts of the subsurface ocean on tropical cyclogenesis have been largely overlooked. Here, we show that the subsurface variabilities associated with the variation in the 26 °C isothermal depth have pronounced impacts on tropical cyclogenesis over global oceans.

The limited transport of oxygen at the solid-liquid interface and the poor charge separation efficiency of single catalyst significantly impedes the generation of reactive oxygen species (ROS), thereby weakening the application potential of photocatalytic technology in water pollution control. Herein, a hollow porous photocatalytic aerogel sphere (calcium alginate/cellulose nanofibers (CA/CNF)) loaded BiOBr/TiC, combining a favourable mass transfer structure with effective catalytic centers was firstly presented. The floatability and hollow pore structure facilitated rapid O transfer via a triphase interface, thereby promoting the generation of ROS.

Two novel and unique adsorptive materials, one (Fluorolock®) from clay mineral sepiolite coated with the cationic polymer polydiallyldimethylammionium chloride (pDADMAC) and the other (Intraplex®) from colloidal activated carbon were specially developed for the in situ remediation of per- and polyfluoroalkyl substances (PFAS) in the saturated zone. We evaluated the potential of both materials to immobilize PFAS in soils under flow conditions via soil column experiments using groundwater, which was contaminated with PFAS in the field. Furthermore, the potential ecotoxicological effects of both materials on aquatic organisms were assessed by exposing the soil column effluent to Daphnia magna.

The purpose of this study is to solve the problem of ammonia (NH) release when modified magnesium slag (MMS) is used as coal mine backfill cementitious material, and to explore its chemical mechanism and put forward effective solutions. Uniaxial compressive strengths (UCS) hydration kinetics, scanning electron microscope (SEM), and thermogravimetric analysis-derivative thermogravimetry (TG-DTG), X-ray diffractometer (XRD) and other testing methods were used to study the evolution of the properties of MMS-based backfill material, which provided a scientific basis for the safe utilization of MMS. First, the chemical mechanism underlying the release of NH from MMS was identified, and it was confirmed that MgN and LiN are the main nitrogen sources.

Internal instability of embankment soils under seepage can occur in two distinct ways: suffusion and suffosion. Suffusion involves the removal of fine particles from the matrix without causing significant disturbance to the soil skeleton, while suffosion is characterized by the movement of fine particles accompanied by skeleton collapse or deformation. In terms of dam safety, suffosion poses a greater threat than suffusion.

The Gravity Recovery and Climate Experiment (GRACE) and its follow-on (GRACE-FO) missions have provided estimates of Terrestrial Water Storage Anomalies (TWSA) since 2002, enabling the monitoring of global hydrological changes. However, temporal gaps within these datasets and the lack of TWSA observations prior to 2002 limit our understanding of long-term freshwater variability. In this study, we develop GRAiCE, a set of four global monthly TWSA reconstructions from 1984 to 2021 at 0.
