Eroding Confidence in Gully Location Risk Prediction in Mine Pit Rehabilitation
Land Degradation &Development, EarlyView.ABSTRACT Understanding how rehabilitation measures, such as landform shaping, and surface finishes impact gully erosion risk could assist in designing less erosive rehabilitation. In this study we use high resolution digital elevation models of rehabilitated mine pits to explore risk factors for gully formation.

A Two‐Stage Optimization Approach for Selecting Electric‐Flight Airports
Networks, EarlyView.ABSTRACT The decarbonization of short‐haul air transport has gained increasing attention, with electric aircraft emerging as a promising alternative to conventional short‐haul aviation. However, given the substantial investment anticipated for the necessary infrastructure, a strategic and globally coordinated selection of airports is imperative.

Propellants, Explosives, Pyrotechnics, EarlyView.ABSTRACT Measuring impulse from explosive charges in contact and near‐field configurations presents practical challenges due to wide variation in impulse magnitude. Ballistic pendula are widely used for impulse measurement, but many existing designs are limited to narrow operating envelopes or are poorly suited to repeated contact testing and tamped ...

Assessment of insecticide use practices in licensed pest control operators in North Carolina
Pest Management Science, EarlyView.A statewide survey of 105 licensed North Carolina pesticide operators found ants, mosquitoes, and aphids as top target pests, pyrethroids as the dominant insecticide class (68%), and limited resistance monitoring, establishing a baseline for future insecticide resistance management and outreach.
