High‐Throughput Quantitative Chemical Shift‐Encoded MRI of the Liver
Journal of Magnetic Resonance Imaging, EarlyView.ABSTRACT Background Access to MRI is limited by lengthy exam times and inefficient utilization. Focused protocols can reduce exam times, but workflow variability and inefficient room turnaround contribute to conservative scheduling with long exam slots.

, 2011 A wheel is a graph formed by a chordless cycle and a vertex that has at least three neighbors in the cycle. We prove that every 3-connected graph that does not contain a wheel as a subgraph is in fact minimally 3-connected. We prove that every graph that does not contain a wheel as a subgraph is 3-colorable.

Journal of Plant Nutrition and Soil Science, EarlyView.We provide a historic overview of microscopic soil structure characterization from its founding father, Walter Kubiëna, to several technical revolutions like automation, digitalization, and artificial intelligence. In addition to technical advancements, we explore how concepts and research questions have evolved in time.

JSFA reports, Volume 5, Issue 3, Page 113-124, March 2025.Abstract Background Most pure maple syrup produced in North America is produced from the sap of sugar maple trees (Acer saccharum). Interest is growing to utilize other maple species in different regions of North America outside the native range of sugar maple.

Multi‐Agent Reinforcement Learning for Joint Police Patrol and Dispatch
Naval Research Logistics (NRL), EarlyView.ABSTRACT Police patrol units need to split their time between performing preventive patrol and being dispatched to serve emergency incidents. In the existing literature, patrol and dispatch decisions are often studied separately. We consider joint optimization of these two decisions to improve police operations efficiency and reduce response time to ...

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

Chi-boundedness of graph classes excluding wheel vertex-minors
, 2018 A class of graphs is \(\chi\)-bounded if there exists a function \(f:\mathbb{N}→\mathbb{N}\) such that for every graph \(G\) in the class and every induced subgraph \(H\) of \(G\), if \(H\) has no clique of size \(q+1\), then the chromatic number of \(H\)
