Seasonal Analysis of Air Pollutants and Ensemble Machine Learning–Based AQI Prediction [PDF]

E3S Web of Conferences
This research investigated the concentration of major air pollutants that vary seasonally and developed a machine learning approach to estimate the Air Quality Index (AQI). Monthly analysis revealed distinct temporal trends, with particulate matter (PM₁₀

Pediatric Drug Adherence and Parental Attention: Evidence From Comprehensive Claims Data

Health Economics, Volume 35, Issue 2, Page 346-359, February 2026.
ABSTRACT Using comprehensive U.S. drug claims data, we show that adherence to asthma control medication declined during the COVID‐19 pandemic. We find that young children exhibited a 40 percent decrease in adherence by the end of 2020. The responses were less negative for older children and positive for adults.

Optimising Wave Energy Plant Location Through Neutrosophic Multi‐Criteria Group Decision‐Making

CAAI Transactions on Intelligence Technology, Volume 11, Issue 1, Page 167-189, February 2026.
ABSTRACT The global shift towards sustainable energy has intensified research into renewable sources, particularly wave energy. Pakistan, with its long coastline, holds significant potential for wave energy development. However, identifying optimal locations for wave energy plants involves evaluating complex, multi‐faceted criteria.

Ensemble learning of model hyperparameters and spatiotemporal data for calibration of low-cost PM2.5 sensors. [PDF]

, 2019
he PM2.5 air quality index (AQI) measurements from government-built supersites are accurate but cannot provide a dense coverage of monitoring areas. Low-cost PM2.5 sensors can be used to deploy a fine-grained internet-of-things (IoT) as a complement to ...

Is Pollution Reduced or Redistributed? The Impact of Electric Vehicle Subsidies in China

Journal of Economics &Management Strategy, Volume 35, Issue 1, Page 59-98, Spring 2026.
ABSTRACT This paper examines the geographically heterogeneous environmental effects of electric vehicle (EV) subsidies in China and compares EV subsidies with alternative policies that price environmental externalities. The study employs a structural model that features demand and supply to analyze the environmental effects of EV subsidies through ...

A Hierarchical Niche Structure, Not Niche Partitioning, Organizes a Seasonally Dynamic Flea Community

Ecology and Evolution, Volume 16, Issue 1, January 2026.
Using seasonal data from a single‐host system (Mongolian gerbil‐flea), we show that community organization is governed by a hierarchical niche structure rather than classic niche partitioning. Network analyses reveal a persistent generalist core with seasonally shifting peripheries (spring assembly, summer integration, autumn reorganization).
