A Heavy‐Duty Vehicle Routing Problem With Temperature Constraints

Networks, Volume 87, Issue 2, Page 131-150, March 2026.
ABSTRACT This article studies a vehicle routing problem involving a fleet of heavy‐duty vehicles and pickup‐and‐delivery requests for crude items that are both heavy and high‐temperature. The objective is to route the fleet in such a way that maximizes resource efficiency and operational efficiency while simultaneously avoiding thermal overload of any ...

Effects of combined prenatal exposure to air pollution and maternal stress on social behavior and oxytocin and vasopressin systems in male and female mice

Journal of Neuroendocrinology, Volume 38, Issue 3, March 2026.
Abstract Prenatal exposures to air pollution and maternal psychosocial stress are each associated with increased risk of neurodevelopmental disorders, including autism spectrum disorder (ASD), and epidemiological work suggests that concurrent exposure to these risk factors may be particularly harmful.

Dusty Streets: The Challenge of Dust‐Borne Pollutants in Low‐Income Countries

CLEAN – Soil, Air, Water, Volume 54, Issue 2, February 2026.
Generally, pollution impacts developed and low‐income countries (LICs) to different extents, and the disease burden due to roadway dust is not uniformly distributed across socio‐economic classes. Roadway dust materials from paved and unpaved urban and rural roads were reported to contain organic constituents which are toxic and affect public health ...

Seeing Through the “FOG” of U.S. Feedstock Incentives for Transportation Fuels

GCB Bioenergy, Volume 18, Issue 2, February 2026.
ABSTRACT The demand for fats, oils, and greases (FOG) as biofuel feedstocks has increased in recent years. Further expansions will have uncertain, but potentially significant, effects on food prices, greenhouse gas emissions, and the U.S. farm economy. To address the market‐mediated effects of expanding FOG feedstock consumption, U.S.
