Living by the Rule:Contemporary Art and the Medieval Monastery
How might assumptions about contemporary life be unsettled by historical models, specifically the 'Rule’ which underpinned medieval monastic life? And how does the rich visual material culture of that historical model find connections with contemporary art? This unique publication offers a vivid means of staging the encounter between the medieval and the contemporary, with many unexpected resonances sounding between recent works and much earlier objects and texts. Offering new perspectives on extraordinary artworks from monastic contexts, such as the Arundel and Gorleston Psalters, and works in a variety of media by celebrated contemporary artists, including Danh Vo, Elizabeth Price, Richard Wright and Andrea Büttner, Living by the Rule makes a compelling case for looking beyond the chronological tracing of art history
The impact of the matrix and buffer properties on residual stresses in TRISO particles during manufacture and early life
A three-dimensional finite-element model was developed using Abaqus to simulate the fabrication and initial power ramp-up of a tri-structural isotropic (TRISO) particle, featuring a UO2 kernel, encapsulated in either a SiC or graphite matrix. After sintering, the residual compressive hoop stress in the SiC coating layer reached -540 MPa when encapsulated in a graphite matrix, 94 MPa more compressive than in a SiC matrix. However, following the initial power ramp-up, the predicted compressive hoop stresses in the SiC layer of a particle embedded in a SiC matrix (-388 MPa) were significantly greater than in a graphite matrix (-222 MPa), emphasizing the matrix material's critical role in the stress state of the SiC layer. Model validation attempts were made with the experimental measurements of the residual stresses of a zirconia-kernel surrogate particle. We found that in a fully-bonded surrogate TRISO particle, the stress state of the SiC layer is highly sensitive to the buffer porosity with compressive SiC layer hoop stresses ranging from up to -1.06 GPa at a porosity of 0.14 to -0.77 GPa at a porosity of 0.60. Partial kernel/buffer delamination simulations revealed a significantly varied geometric stress distribution, with tensile stresses reaching up to +54 MPa and compressive stresses up to -546 MPa at different axes of the sectioned plane in the model. This finding suggests that contrary to the common assumption of complete delamination at the kernel/buffer interface during fabrication, partial delamination is a more plausible explanation for the high compressive stresses observed in the SiC layer experimentally
Intensive land use enhances soil ammonia-oxidising archaea at a continental scale
Archaea are an important group of soil organisms that play key roles in carbon and nitrogen cycling, particularly in nitrification (ammonia oxidation) and methanogenesis. However, there are knowledge gaps regarding their importance in ecosystem processes relative to other microbial groups and how they may be impacted by land-use and environmental changes. Here, by carrying out a continental-scale sample collection and utilising archaea-specific primers for metabarcoding and shotgun metagenomics, we aimed to decipher the structure and function of archaeal communities across various land-use types in Europe. Metagenomic data reveal that land-use intensification increases the relative abundance of archaea, whereas bacteria and eukaryotes show no increase. Alongside this, ammonia oxidising archaea (AOA) increase as a proportion of the total metabarcoding reads, from 1 % of archaea in coniferous woodland to >90 % in croplands. Functional gene profiles reveal that land-use intensification shifts archaeal communities from adaptive metabolic pathways in forests to specialised, ammonia-oxidising microbes in fertiliser-enriched cropland soils. Our data suggest that land-use intensification may shift archaeal communities toward greater dependence on external nitrogen inputs, with potential consequences for soil fertility and greenhouse gas emissions
Decolonising Intellectual Property Law:An Afrocentric Approach
This book advocates for an Afrocentric approach to intellectual property (IP) law, using lessons from Nigeria’s past to encourage reform for the future of Africa’s legal IP landscape. Highlighting the Eurocentric influence on the history of intellectual property law in Africa, the book demonstrates how this contradicts traditional African community culture. This book makes the case for legitimising cultural expressions of traditional communities despite the western legal framework within which they exist, reimagining a decolonised IP framework whereby African histories are centred. Questioning the fundamentals of the current IP landscape, such as the concept of eligibility in copyright which developed alongside European technological advances, the book also details the role of the courts in resolving IP disputes. It highlights Africa as a powerhouse of original, autonomous innovation, values and traditions which predate the West’s concept of intellectual property. It illustrates the African experience of intellectual property from a pro-African perspective as shared by African authors. This book will be of interest to researchers in the field of Intellectual Property, copyright and patent law, as well as African law
A medicines information department simulation for final year MPharm undergraduates
Background: Final year pharmacy students in the UK need to demonstrate competence in a range of learning outcomes including working in partnership, communication skills, working collaboratively, appraising the evidence base, critically evaluating guidelines, effective leadership, and responding to complaints. Medicines Information (MI) departments in the UK provide support for all aspects of medication related queries and working in MI requires these skills to ensure the safe and effective use of medicines. Educational activity: An MI themed simulation was developed for final year MPharm students at the University of East Anglia as an opportunity for them to develop in a range of skills and utilise previously taught clinical knowledge. Students were divided into two teams of five students, each tasked with managing their own MI department. During the four-hour simulation each team received a total of 12 telephone enquiries from a variety of simulated health professionals and simulated patients. Evaluation findings: All 10 students participated in a focus group exploring their experience of the simulation. A thematic analysis identified three themes; realism, management and teamwork, and preparation for practice. Analysis of educational activity: Students felt the simulation was realistic and challenging. They did not see management skills as integral to the task at the outset, however there was evidence of a change in approach as the simulation progressed. The session supported development of research and communication skills and was an opportunity for students to apply clinical knowledge. As such, an MI department simulation activity may be a useful addition to pharmacy curricula

Robust Noisy Pseudo-Label Learning for Semi-supervised Medical Image Segmentation Using Diffusion Model
Obtaining pixel-level annotations in the medical domain is both expensive and time-consuming, often requiring close collaboration between clinical experts and developers. Semi-supervised medical image segmentation aims to leverage limited annotated data alongside abundant unlabeled data to achieve accurate segmentation. However, existing semi-supervised methods often struggle to structure semantic distributions in the latent space due to noise introduced by pseudo-labels. In this paper, we propose a novel diffusion-based framework for semi-supervised medical image segmentation. Our method introduces a constraint into the latent structure of semantic labels during the denoising diffusion process by enforcing prototype-based contrastive consistency. Rather than explicitly delineating semantic boundaries, the model leverages class prototypes centralized semantic representations in the latent space as anchors. This strategy improves the robustness of dense predictions, particularly in the presence of noisy pseudo-labels. We also introduce a new publicly available benchmark: Multi-Object Segmentation in X-ray Angiography Videos (MOSXAV), which provides detailed, manually annotated segmentation ground truth for multiple anatomical structures in X-ray angiography videos. Extensive experiments on the EndoScapes2023 and MOSXAV datasets demonstrate that our method outperforms state-of-the-art medical image segmentation approaches under the semi-supervised learning setting. This work presents a robust and data-efficient diffusion model that offers enhanced flexibility and strong potential for a wide range of clinical applications
Enduring the heat: The microclimate characteristics that determine site suitability for an endangered grassland bird during post-breeding
Environmental changes, including habitat loss and fragmentation in combination with climate change, have increased population reliance on protected areas (PAs) while also requiring individuals to adapt to changing local conditions or search for refugia when conditions deteriorate. Microclimate refugia within PAs may be critical for allowing species to persist when exposed to extreme thermal conditions, yet the availability of microclimate refugia and the ability of PAs to protect species from extremes has rarely been considered. We GPS-tracked 47 little bustards (Tetrax tetrax) in the Iberian Peninsula in 2009–2019, to understand their micro-scale climate and habitat use in the warmest period of the year, the post-breeding season. We compared post-breeding conditions at locations used in that period with those not used after breeding. We found that increasing temperature may reduce site suitability, while sites with greater microclimate refugia availability were more likely to be used by little bustards post-breeding. Although dispersed shrubs may provide micro-refugia, dense shrubby patches were avoided. While almost 63 % of the breeding locations were in PAs, only under 7 % of all post-breeding locations were within these key conservation areas, showing this species is not well protected across its life cycle. We assessed the impact of expected increasing temperatures from climate change scenarios and found that up to 15 % of currently used locations are predicted to become unsuitable, including those falling within PAs. Habitat management strategies should maintain landscapes with diverse characteristics that may provide shelter from extreme temperatures, such as scarce patches of low-density shrubs
