Maximizing Revenues for On-Line Dial-a-Ride

open access: yes, 2014
In the classic Dial-a-Ride Problem, a server travels in some metric space to serve requests for rides. Each request has a source, destination, and release time. We study a variation of this problem where each request also has a revenue that is earned if the request is satisfied.

Leveraging Public Transit for Robotic Deliveries: A Column Generation Approach

open access: yesNaval 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

Semi‐automated MicroED system unveils multiple polymorphs in fish‐derived guanine crystals

open access: yesActa Crystallographica Section C, Volume 82, Issue 7, Page 310-323, July 2026.
A semi‐automated MicroED data collection and processing system was established and shown to be suitable for the structural investigation of submicrometer‐scale biogenic crystals.Certain fish display silvery or blue colour, not through pigments, but through specialized guanine crystals that exist within iridophore cells in their skin. Within these cells,
