Enduring circumstances
No full textEnduring Circumstances presented newly commissioned films by Jennie Pedley, Paris Petridis and Penny Siopis, 26 September - 21 November 2022. Crises have the quality of urgency. But their causes may be of longer duration, and strategies for survival slower and steadier. Enduring Circumstances brings together three artworks responding to the social effects of crisis. Using the durational qualities of video, these works address the cataclysm of the pandemic to ask: what is the interaction between human health and habitat? How does the representation of daily rituals offer deep reflection on the passing of time and being in the world? How might art interrogate the basis of long-standing patterns of harm? Contemporary artists Jennie Pedley, Paris Petridis, and Penny Siopis each turn their attention to these questions in works that engage with the material of the body, remediate everyday experience, and investigate the archival traces of social relationships. Originally commissioned as part of Peltz Gallery's Lessons from Lockdown: Learning from the Pandemic (2020-21).
nudity I was interested to note the passing of my generation: two years ago every second man had a wound mark, but I did not see one today.' As the 1930s sunbathing craze took hold, the riverbank was quadrupled in size to make way for more reclining bodies, and a family equivalent opened next door, called Dame's Delight. Then, in the Second World War, the site again reconfigured itself, with soldiers posted in Oxford gaining leave to bathe there in their time-off. By the postwar period Parson's Pleasure was known as a cruising spot, featuring as a 'swimming place' in the 1962 edition of the Guide Gris, an early gay travel guide. Parson's Pleasure was demolished and a bonfire made of its sheds and screens in January 1992. Duncan Montgomery's new series of wood engravings and the contextual material provided here by George Townsend represent work in progress in a project to illustrate and enrich the findings of Townsend's recent doctoral thesis, A Cultural History of Parson's Pleasure (2022)
Flavour-changing neutral currents making and breaking the standard model
No full textThe standard model of particle physics is our best description yet of fundamental particles and their interactions, but it is known to be incomplete. As yet undiscovered particles and interactions might exist. One of the most powerful ways to search for new particles is by studying processes known as flavour-changing neutral current decays, whereby a quark changes its flavour without altering its electric charge. One example of such a transition is the decay of a beauty quark into a strange quark. Here we review some intriguing anomalies in these decays, which have revealed potential cracks in the standard model—hinting at the existence of new phenomena
Virtual Stonehenge Reconstruction
No full textVisual and spatial technologies are increasingly revolutionising how archaeology and many other disciplines understand the past in relation to the contemporary world. From digital objects to landscapes, through geophysics, geographical imaging systems and the creation of virtual worlds, new technology provides alternative routes to seeing and understanding both past and present [1]. This research paper describes an interdisciplinary art and design approach to rebuilding and visualising phase 3vi of the Stonehenge site for interactive cultural heritage applications in the 21st Century. A 3D digital research team based at the School of Art, Design & Architecture collaborated with music technologists, sculptors and game designers to gather, interpret, re-imagine and digitally re-model historical and contemporary data on Stonehenge to create a virtual 3D reconstruction of Stonehenge phase 3vi. The researchers discuss the range of digital data, tools, methods used in this phase of the Virtual Stonehenge reconstruction project
Late Antique and Medieval Pottery from Phoinike (Albania)
No full textSince 2015 a new systematic study has been made from medieval pottery, found in Phoinike (Albania) excavations conducted by the Italian Archaeological Mission and the Institute of Archaeology, during the last fifteen years. Insight provided by these archaeological contexts demonstrates an extraordinary trend whereby the Albanian site received goods coming from north Tunisian commerce (fine wares, olive oil, fish sauce) and from Eastern Mediterranean regions (olive oil and different qualities of wine) until the eight century AD. There is also notable evidence of Epirus products, overall cooking ware and wine amphorae, exported toward other close cities and Apulia. The city also shows a long period of occupation and transformations during the Middle Ages and after the Turkish conquest until the second half of the sixteenth century. This is a new perspective that shows the continuity and revival of maritime trade circulation in the Corfu channel even during the early Middle Ages

SuperHistopath: A Deep Learning Pipeline for Mapping Tumor Heterogeneity on Low-Resolution Whole-Slide Digital Histopathology Images
No full textHigh computational cost associated with digital pathology image analysis approaches is a challenge towards their translation in routine pathology clinic. Here, we propose a computationally efficient framework (SuperHistopath), designed to map global context features reflecting the rich tumor morphological heterogeneity. SuperHistopath efficiently combines i) a segmentation approach using the linear iterative clustering (SLIC) superpixels algorithm applied directly on the whole-slide images at low resolution (5x magnification) to adhere to region boundaries and form homogeneous spatial units at tissue-level, followed by ii) classification of superpixels using a convolution neural network (CNN). To demonstrate how versatile SuperHistopath was in accomplishing histopathology tasks, we classified tumor tissue, stroma, necrosis, lymphocytes clusters, differentiating regions, fat, hemorrhage and normal tissue, in 127 melanomas, 23 triple-negative breast cancers, and 73 samples from transgenic mouse models of high-risk childhood neuroblastoma with high accuracy (98.8%, 93.1% and 98.3% respectively). Furthermore, SuperHistopath enabled discovery of significant differences in tumor phenotype of neuroblastoma mouse models emulating genomic variants of high-risk disease, and stratification of melanoma patients (high ratio of lymphocyte-to-tumor superpixels (p = 0.015) and low stroma-to-tumor ratio (p = 0.028) were associated with a favorable prognosis). Finally, SuperHistopath is efficient for annotation of ground-truth datasets (as there is no need of boundary delineation), training and application (~5 min for classifying a whole-slide image and as low as ~30 min for network training). These attributes make SuperHistopath particularly attractive for research in rich datasets and could also facilitate its adoption in the clinic to accelerate pathologist workflow with the quantification of phenotypes, predictive/prognosis markers
Impact of different cannulation strategies on in-hospital outcomes of aortic arch surgery: a propensity-score analysis.
No full textAbstract
BACKGROUND:
The impact of different cannulation strategies on outcomes of aortic arch surgery remains controversial. This retrospective study sought to evaluate central cannulation (ascending aorta, right axillary, and innominate artery) compared with femoral artery cannulation for aortic arch surgery, and to identify among preoperative and intraoperative variables the independent predictors of death and permanent neurologic dysfunction (PND) in aortic arch surgery.
METHODS:
All patients were operated through a median sternotomy using antegrade selective cerebral perfusion with moderate hypothermia as a method of brain protection. Treatment bias was addressed by use of propensity-score matching and multivariate regression analysis. Logistic regression models were used to identify the independent predictors of hospital mortality and PND.
RESULTS:
Of the 473 patients undergoing aortic arch surgery, 273 (57.7%) underwent femoral cannulation (FC), and 200 (42.3%) underwent central cannulation (CC). The CC and FC cannulation were associated with similar risk of in-hospital death (absolute risk reduction [ARR]: 0.7%; p = 0.880) and PND (ARR:-2.6%, p = 0.361) in the overall cohort and after adjusting for propensity-based matching (ARR for hospital mortality: 2.2%, p = 0.589; ARR for PND: 3.4%, p = 0.271). Female gender (odds ratio [OR]:2.1, p = 0.030), type A acute dissection or intramural hematoma (OR: 2.2; p = 0.041), and CPB time (OR: 1.010/minute, p = 0.015) were independent predictors of in-hospital death. Female gender (OR: 2.4; p = 0.033), type A acute dissection or intramural hematoma (OR: 4.2; p = 0.005), and diabetes (OR: 6.6, p = 0.007) were independent predictors of PND.
CONCLUSIONS:
During aortic arch surgery, CC and FC are associated with a similar risk of postoperative death and PND. Type A acute aortic dissection and cardiopulmonary bypass time remain strong risk factors for mortality and PND
