Leveraging Public Transit for Robotic Deliveries: A Column Generation Approach
Naval Research Logistics (NRL), EarlyView.ABSTRACT Autonomous mobile robots (AMRs) are small, electric, wheeled vehicles that operate at pedestrian speeds. In the last‐mile delivery service considered in this study, a fleet of AMRs is deployed across multiple recharging depots within a service area, from which they depart to perform point‐to‐point deliveries. We consider an operational setting

Exact Methods for the Cumulative Capacitated Vehicle Routing Problem With Time Windows
Networks, EarlyView.ABSTRACT This article studies the cumulative capacitated vehicle routing problem with time windows (CCVRPTW). The CCVRPTW consists of deciding the routing schedules for a set of homogeneous capacitated vehicles such that the latency, that is, the sum of the service start times at the customers, is minimized and the time windows as well as the vehicle ...

From Data to Knowledge to Wisdom: Lessons Learned From the Vancouver Rat Project
Integrative Zoology, EarlyView.A synthesis of 15 years of research conducted by the Vancouver Rat Project revealed that: (1) Pathogen ecology within rat colonies is the result of complex interactions among rats, pathogens, and vectors. (2) Local and global population structures influence rat and pathogen ecology.

Insect Conservation and Diversity, EarlyView.Urbanization drives turnover in dragonfly species composition, traits, and habitat conservation value. Natural stream sections have a higher conservation value (higher DBI) due to presence of specialists. Properly managed urban streams can support diverse dragonfly assemblages.
