Climatic–Anthropogenic Synergy Drives Escalating Minimum Area Requirements and Connectivity‐Protection Mismatch in a Karst‐Endemic Primate

Integrative Zoology, EarlyView.
Climate change and anthropogenic activities drive antagonistic degradation of landscape connectivity for endangered François’ langur (1987–2024), causing 48.8% habitat loss, north‐south fragmentation, and centroid migration (1.2 km/yr). Despite protected areas buffering connectivity, static management fails dynamic priority habitats; we propose ...

A Survey of Methods for Constructing 3D Urban Models From Point Clouds

Computer Graphics Forum, EarlyView.
The survey outlines a general process for constructing 3D models from point clouds and categorizes the methods based on their use of templates, basic surface primitives, hybrid approaches, or linear primitives. Additionally, the survey reviews the datasets and benchmarks that are essential for testing and training the developed methods.

Freight distribution optimization by implementing the team orienteering problem with occasional drivers

International Transactions in Operational Research, EarlyView.
Abstract This research evaluates the effectiveness of a hybrid crowdshipping system that integrates occasional drivers with traditional delivery services (OD+TD) to improve the efficiency of freight distribution. By implementing the team orienteering problem with occasional drivers model, we develop a mathematical model and an agile optimization ...

Challenges to artificial intelligence‐enabled digital technology adoption in farms: a multi‐method approach

International Transactions in Operational Research, EarlyView.
Abstract Artificial intelligence (AI)‐enabled digital technologies have the potential to transform agriculture by supporting decision‐making and automating operations. However, their limited adoptions and scholars’ atheoretical explorations constrain our understanding.

Russia's Wartime Economy: Measuring Regional Inequalities From Outer Space

Journal of Regional Science, EarlyView.
ABSTRACT We study Russia's February 2022 full‐scale invasion of Ukraine as a natural experiment to determine how sudden disruptions to international market access reshape sub‐national economic inequalities. Using remotely‐sensed nighttime lights as a proxy for economic activity, we estimate the economic effects of the war at the national and regional ...
