Life Cycle Assessment of Waste Oil-to-Jet Fuel Production via the HEFA Process with Integrated Co-generation

This study employs life cycle assessment to demonstrate that while the HEFA process integrated with co-generation offers superior near-term environmental performance for waste oil-to-jet fuel production, its carbon mitigation benefits diminish with grid decarbonization and the use of wind-powered electrolytic hydrogen introduces significant human toxicity risks due to wind equipment manufacturing.

A Harmonization Index for Comparative Assessment of Industrial Particulate Matter Emission Regulations

This study introduces a standardized Regulatory Coding Framework and Harmonization Index to systematically benchmark industrial particulate matter emission regulations across the EU, US, China, and Uzbekistan, revealing significant regulatory divergences beyond numerical limits and providing a robust, reproducible tool for evidence-based policy modernization and international comparison.

Predicting the potential geographic distribution of the invasive ambrosia beetles, 1 Xylosandrus crassiusculus (Coleoptera, Curculionidae) under climate change

Using the MaxEnt model, this study predicts that the invasive ambrosia beetle *Xylosandrus crassiusculus* will experience a slight expansion in its highly suitable habitat by 2080 under climate change scenarios, driven primarily by precipitation and temperature factors, thereby highlighting the need for enhanced monitoring and management strategies.

Evidence from India on climate anomalies and the multiple dimensions of adolescent wellbeing

Using longitudinal data from India, this study reveals that higher rainfall anomalies negatively impact multiple dimensions of adolescent wellbeing—including subjective life satisfaction, self-efficacy, self-esteem, and emotional distress—primarily through mechanisms of food insecurity and child health, without significant buffering from major social welfare programs.

Reconstructing Paleo-ecosystems in Mesopotamia: Evidence from fauna in southern Iraqi sediments

This study reconstructs the early Holocene paleoenvironment of the Khor Abdullah region in southern Iraq by analyzing four faunal groups (Foraminifera, Ostracoda, Mollusca, and Bryozoa) in subbottom cores, revealing a transition from freshwater conditions to a marine transgression in a marshy, turbid setting followed by regression.

Multi-Scenario Evolution of The Water-Energy-Food Nexus based on Multi-Task Residual Network Model

This study introduces a Multi-Task Residual Network (MTRNet) framework to analyze and project the Water-Energy-Food (WEF) Nexus across 300+ Chinese cities, revealing that sustainable development pathways foster synergy while high-carbon scenarios risk divergence, thereby advancing the field from static description to mechanism-aware forecasting.

Exceptional Heat Stress Drives Coral Bleaching Across Japan in 2024

The 2024 global bleaching event caused exceptional heat stress and widespread coral bleaching across Japan's entire latitudinal range from tropical Ryukyus to temperate Pacific coasts, driven by anomalous thermal anomalies that exceeded local baselines and reached Alert Level 3 severity.

Fragmented Corrections to the van Genuchten–Mualem Model Diverge by 24–68% from a Consistent Coupled Parameterization: A Quantitative Demonstration for Thermal, Osmotic, and Hysteretic Conditions

This paper demonstrates that the fragmented, inconsistent application of separate corrections for temperature, salinity, and hysteresis to the van Genuchten–Mualem model introduces significant quantitative errors (24–68%) in predicting soil water flow, and proposes a unified, closed-form parameterization that resolves these inconsistencies by rigorously coupling these factors without introducing new parameters.
