Novel Methods in Cladoceran Size Structure Analysis Reveal ~60 Years of Trophic Change in a Sediment Core From a Great Lakes Area of Concern (Bay of Quinte, Lake Ontario)

open access: yesFreshwater Biology, Volume 70, Issue 10, October 2025.
ABSTRACT Nutrient loading, aquatic invasive species, and climate warming have altered food web dynamics in the Great Lakes. Long‐term data are required to characterise the response of the lower food web to multiple environmental drivers and develop trophic indicators for future research and management efforts.

End‐to‐end instance segmentation framework for automated pavement distress assessment using unmanned aerial vehicle‐derived digital orthophoto maps

open access: yesComputer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 24, Page 4055-4075, 6 October 2025.
Abstract This study presents a novel framework for automated detection and segmentation of pavement distresses using high‐resolution digital orthophoto maps captured by unmanned aerial vehicles (UAVs). While recent UAV‐based research often relies on manual measurements from rasterized digital models, only a few studies have employed automated methods ...

Crossing estimates for the Ising model on general s‐embeddings

open access: yesProceedings of the London Mathematical Society, Volume 131, Issue 4, October 2025.
Abstract We prove Russo–Seymour–Welsh‐type crossing estimates for the FK–Ising model on general s‐embeddings whose origami map has an asymptotic Lipschitz constant strictly smaller than 1, provided it satisfies a mild non‐degeneracy assumption. This result extends the work of Chelkak and provides a general framework to prove that the usual connection ...

The Complexity of Guarding Monotone Polygons

open access: yes, 2012
A polygon P is x-monotone if any line orthogonal to the x-axis has a simply connected intersection with P. A set G of points inside P or on the boundary of P is said to guard the polygon if every point inside P or on the boundary of P is seen by a point in G. An interior guard can lie anywhere inside or on the boundary of the polygon. Using a reduction
