Wave Impacts On Vertical Cliffs: Insights From Laboratory Experiments And Field Observations, Yaxiong Shen, Colin N. Whittaker, Catriona F. Thompson, Alison C. Raby, Adam P. Young, Mark E. Dickson

School of Engineering, Computing and Mathematics

Many engineered and natural coastal structures suffer frequent damage from wave impacts. Motivated by field observations of wave impacts on coastal cliffs, we undertake controlled physical experiments with synchronised measurements of wave properties and their impacts on a vertical structure representing a cliff. Laboratory experiments using focused wave groups show that, in the investigated scenarios, large impacts occur within a relatively narrow phase range (−30° to 35°), covering ∼20% of the full phase range. Our irregular wave experiments indicate that ∼30% of waves break onto or near the cliff face, although not all these breaking waves result in large impacts. …

The Power Of ‘Net Zero’: Seductive Dispossession On The Critical Minerals Frontier, Dayna Scott Oct 2025

The Power Of ‘Net Zero’: Seductive Dispossession On The Critical Minerals Frontier, Dayna Scott

Articles & Book Chapters

This article draws on insights gained from many years of community-engaged work alongside Neskantaga First Nation, a small remote Anishinaabe community in Treaty No.9, whose Indigenous homelands are being pressured by the global thirst for critical minerals. In line with recent writing on 'green extractivism', I detail how mining's new legitimacy in the boreal peatlands of the far north of Ontario, Canada, gained strength over the past decade from a pitch that associates it with battery metals for electric vehicles, and thus the transition to a 'net-zero' economy. The seduction obscures the social and ecological destruction that mining entails, and …

2020-Current year OA Pubs

Sensory cells often adopt specific morphologies that aid in the detection of external stimuli. Merkel cells encode gentle touch stimuli in vertebrate skin and adopt a reproducible shape characterized by spiky actin-rich microvilli that emanate from the cell surface. The mechanisms by which Merkel cells acquire this stereotyped morphology from keratinocyte progenitors are unknown. Here, we establish that dendritic Merkel cells (dMCs) express atonal homolog 1a (atoh1a), extend dynamic filopodial processes, and arise in transient waves during zebrafish skin development and regeneration. We find that dMCs share molecular similarities with both basal keratinocytes and Merkel cells, yet display mesenchymal-like behaviors, …

Mathematics & Statistics Faculty Works

Multiplexed imaging allows multiple cell types to be simultaneously visualised in a single tissue sample, generating unprecedented amounts of spatially-resolved, biological data. In topological data analysis, persistent homology provides multiscale descriptors of “shape" suitable for the analysis of such spatial data. Here we propose a novel visualisation of persistent homology (PH) and fine-tune vectorisations thereof (exploring the effect of different weightings for persistence images, a prominent vectorisation of PH). These approaches offer new biological interpretations and promising avenues for improving the analysis of complex spatial biological data especially in multiple cell type data. To illustrate our methods, we apply them …
