Comparative Field Evaluation of Active and Passive Transient‐Based Techniques for Pipeline Condition Assessment

open access: yesWater Resources Research, Volume 62, Issue 9, September 2026.
Abstract Hydraulic transient‐based techniques are increasingly applied for non‐intrusive condition assessment of buried water pipelines. This study presents systematic field experiments comparing active and passive approaches within the asbestos cement water supply network at the University of Canterbury.

Facilitating macrosystem biology with organismal‐scale airborne remote sensing: Challenges and opportunities

open access: yesFunctional Ecology, Volume 40, Issue 9, Page 2760-2776, September 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Emergent ecosystem properties, such as population and trait distributions, biodiversity and energy and water fluxes, occur because of the dynamic interactions of individuals in their environment.

Dynamic margin contrastive learning for open-set recognition in long-tailed sonar imagery

open access: yesScientific Reports
Long-tail distribution and open-set recognition remain significant challenges in sonar image classification. This study introduces Dynamic Margin Contrastive Learning (DMCL), a novel framework that simultaneously addresses both issues through adaptive ...

Cache‐Cache: Dans les souffles du Grand Fleuve…

open access: yesAnthropology of Consciousness, Volume 37, Issue 2, Fall 2026.
ABSTRACT Between ventriloquism and divination, devotion and consecration, an old and sublime marine game unfolds each day, with living breaths shared in the waters of the great river. In Tadoussac, on the north shore of the St. Lawrence Estuary, at the mouth of the Saguenay, the rumor of whales has long resonated.

Muralismo como encargo participativo: Holografía de lo (in)visible en comunidades a’i cofán de la selva colombiana

open access: yesAnthropology of Consciousness, Volume 37, Issue 2, Fall 2026.
ABSTRACT When mural art in indigenous communities is commissioned as a participatory project, several methodological, epistemological, and aesthetic questions arise. This text proposes a horizontal and investigative approach to what we can simply call ‘muralism in the A'i Cofán community context,’ not as significant works executed in communities, but ...

Label field initialization for MRF-based sonar image segmentation by selective autoencoding

open access: yes, 2016
The optimal solution of a Markov random field (MRF) can be solved by constructing a Markov chain that eventually goes to a balance state. However, in most situations, only an suboptimal solution can be obtained, because it is hard to choose the ideal ...
