The team orienteering problem with variable time windows

open access: yesInternational Transactions in Operational Research, Volume 33, Issue 3, Page 1705-1732, May 2026.
Abstract The orienteering problem is well‐established within the domain of operational research. This paper introduces the team orienteering problem with variable time windows (TOPVTW) as a new variant of the team orienteering problem with time windows. The distinguishing feature of the TOPVTW is the adaptive time windows, which evolve dynamically as a

Things at Work: How Things Contribute to Performing Work

open access: yesJournal of Management Studies, Volume 63, Issue 3, Page 1155-1191, May 2026.
Abstract A crucial question for organizations is what constitutes work performance. While the importance of human competence and motivation to work performance has been established, less well understood is how ‘things’ – such as algorithms, tools, instruments, and raw materials – contribute to work performance.

Unmated Queens Show Worker‐Like Behaviour and Gene Expression in Polygynous Colonies of the Ant Stigmatomma pallipes

open access: yesMolecular Ecology, Volume 35, Issue 9, May 2026.
ABSTRACT Insect societies show a reproductive division of labor between egg‐laying queens and workers that fulfil all non‐reproductive tasks. Polygyny, the coexistence of several queens in a colony, has evolved multiple times in social insects. Although queens in polygynous colonies are often assumed to have similar reproductive outputs, they may ...

Energy Consumption Optimization in Trajectory Planning for Fuel Cell Hybrid Uavs Based On HMPC

open access: yesAdvanced Robotics Research, Volume 2, Issue 2, April 2026.
The endurance limitation of multirotor drones is a critical challenge. This study adopts a hybrid power system of fuel cells and lithium‐ion batteries. Using Nondominated Sorting Genetic Algorithm II, it integrates trajectory planning with energy management optimization.
