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. …

SKMC Student Presentations and Publications

Hydralazine (HYZ), a treatment for preeclampsia and hypertensive crisis, is listed by the World Health Organization as an essential medicine. Its mode of action has remained unknown through its seven decades of clinical use. Here, we identify 2-aminoethanethiol dioxygenase (ADO), a key mediator of targeted protein degradation, as a selective HYZ target. The drug chelates ADO's metallocofactor and can alkylate one of its ligands. The resultant inactivation stabilizes regulators of G protein signaling (RGS4 and RGS5) that ADO normally marks for proteolysis, explaining the drug's vasodilatory activity and comporting with observations of diminished RGS levels in both clinical preeclampsia and …

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 …

Estrogen-Related Receptor Alpha Promotes Skeletal Muscle Regeneration And Mitigates Muscular Dystrophy, Thi Thu Hao Nguyen, Ya Xiang Huang, Svitlana Poliakova, Citu Citu, Eira Mann, Danesh H Sopariwala, Zhongming Zhao, Ashok Kumar, Vihang A Narkar

The Brown Foundation: Institute of Molecular Medicine

Skeletal muscle regeneration in chronic muscle diseases such as Duchenne Muscular Dystrophy (DMD) has remained clinically unsurmountable. Estrogen‐related receptor alpha (ERRα) plays a critical role in adult skeletal muscle metabolism and exercise fitness. Whether ERRα activation can drive muscle regeneration and mitigate dystrophy in DMD is not known. We have investigated ERRα signaling in pre‐clinical models of acute muscle injury and DMD. ERRα is induced in differentiating C2C12 myoblast and regenerating muscle. ERRα silencing suppressed proliferation and differentiation in C2C12 myoblasts. RNA sequencing revealed that angiogenic factor and proliferation genes were downregulated by ERRα knockdown in proliferating cells, whereas oxidative …

Understanding Callus Types In Maize By Genetic Mapping And Transcriptional Profiling, Guifang Lin, Yan Liu, Tej Man Tamang, Yang Qin, Mingxia Zhao, Hairong Wei, Et. Al.

Michigan Tech Publications

Plant transformation efficiency is highly dependent on species, individual genotypes, and tissue types. In maize, immature embryos are regularly used for transformation. The process relies heavily on callus development, as it is intricately associated with somatic embryogenesis and subsequent plant regeneration, both of which directly affect transformation efficiency. Immature embryos of the segregation progeny derived from the two inbred parents, a transformation-amenable line A188 and a recalcitrant line B73, can be cultured to form two primary callus types: Type I and Type II. The Type II callus grows faster and is a favorable type for regeneration. Here, Type I and …

Topology Across Scales On Heterogeneous Cell Data, M. Torras-Pérez, Iris Yoon , '13, P. Weeratunga, L.-P. Ho, H. M. Byrne, U. Tillmann, H. A. Harrington

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 …

Libel Via Language Models, Peter Wills

Osgoode Hall Law Journal

This article explains how developers and users of large language models (LMs) may be treated by English and Canadian libel law. LMs could be economically significant, and the liability environment they exist in will affect where they are developed, who accumulates wealth from their development, and who bears the burdens of any negative consequences of their development. Understanding the existing liability environment allows both developers and policy makers to make informed decisions—about which jurisdiction to offer services and what to prioritise, for the former, and about whether the existing law serves desired policy ends, for the latter. LMs also raise …

Life at Stake in Technology: A Theological-Ethical Approach to Procreative Responsibility

In an age when artificial intelligence and genetic engineering shape life's origins, human procreation stands at a decisive threshold. This article offers theological and ethical reflection on human agency before technological power. Beyond biomedical concerns, it examines how digitization unsettles freedom, dignity, and divine providence. Drawing upon Catholic tradition—from Augustine to John Paul II—it proposes renewed theology of co-creation, wherein human creativity becomes participation in life-giving. Through Imago Dei and moral discernment, it contends that progress must serve life, not fabricate it. Christological ethics can guide reproductive technologies toward …

Cerebellar Dysfunction In Glaucoma Patients, Anisha Kasi, Ji Won Bang, Vivek Trivedi, Jeannie Au, Ian Conner, Gadi Wollstein, Joel Schuman, Rakie Cham, Kevin Chan

Wills Eye Hospital Papers

Glaucoma patients often have higher injurious fall rates compared to healthy older adults. However, little is known about the underlying neural mechanisms. Recent evidence shows cerebral changes beyond the visual pathway of glaucoma patients, yet it remains unclear whether the cerebellum, which plays an important role in balance and motor control, is involved in glaucoma. In this study, we sought to investigate cerebellar functional connectivity changes in glaucoma by comparing 32 glaucoma subjects and 10 age-matched healthy control subjects who underwent resting-state functional magnetic resonance imaging at 3 Tesla with eyes closed. After conducting both regions-of-interest and seed-to-voxel analyses, we …

Faculty Publications

Cadmium silicon phosphide (CdSiP₂) is a nonlinear optical material widely used in optical parametric oscillators. Intrinsic defects (vacancies and antisites) are responsible for unwanted broad optical absorption bands in these crystals that degrade the performance of the devices. In the present work, optical absorption and electron paramagnetic resonance (EPR) spectra are acquired (at room temperature and 12 K, respectively) from a neutron-irradiated CdSiP₂ crystal. After the irradiation, the crystal is highly absorbing from the band edge near 600 nm to beyond 1.3 μm because of overlapping defect-related absorption bands. Heating to 550 °C removes nearly all the …
