Applications of Artificial Intelligence in Live Action Role-Playing Games (LARP)
Live Action Role-Playing (LARP) games and similar experiences are becoming a
popular game genre. Here, we discuss how artificial intelligence techniques,
particularly those commonly used in AI for Games, could be applied to LARP. We
discuss the specific properties of LARP that make it a surprisingly suitable
application field, and provide a brief overview of some existing approaches. We
then outline several directions where utilizing AI seems beneficial, by both
making LARPs easier to organize, and by enhancing the player experience with
elements not possible without AI.Comment: 8 pages, 2 figures. Published at IEEE Conference on Games, 202
The use of targeted sequencing and flow cytometry to identify patients with a clinically significant monocytosis
The diagnosis of chronic myelomonocytic leukaemia (CMML) remains centred on morphology, meaning the distinction from a reactive monocytosis is challenging. Mutational analysis and immunophenotyping have been proposed as potential tools for diagnosis however have not been formally assessed in combination. We aimed to investigate the clinical utility of these technologies by performing targeted sequencing, in parallel to current gold standard techniques, on consecutive samples referred for investigation of monocytosis over a 2-year period (n=283). Results were correlated with the morphological diagnosis and objective outcome measures including overall survival (OS) and longitudinal blood counts. Somatic mutations were detected in 79% of patients, being invariably identified in those with a confirmed diagnosis (99%) though also in 57% of patients with non-diagnostic BM features. The OS in non-diagnostic mutated patients was indistinguishable from those with CMML (p=0.118) and significantly worse than unmutated patients (p=0.0002). On multivariate analysis age, ASXL1, CBL, DNMT3A, NRAS & RUNX1 mutations retained significance. Furthermore, the presence of a mutation was associated with a progressive fall in haemoglobin/platelet levels and increasing monocyte counts compared with mutation negative patients. Of note, the immunophenotypic features of non-diagnostic mutated patients were comparable to CMML patients and the presence of aberrant CD56 was highly specific for detecting a mutation. Overall, somatic mutations are detected at high frequency in patients referred with a monocytosis irrespective of diagnosis. In those without a WHO defined diagnosis, the mutation spectrum, immunophenotypic features and OS are indistinguishable from CMML patients and these patients should be managed as such
Tumour Cell Generation of Inducible Regulatory T-Cells in Multiple Myeloma Is Contact-Dependent and Antigen-Presenting Cell-Independent
Regulatory T-cells (TReg cells) are increased in patients with multiple myeloma (MM). We investigated whether MM cells could generate and/or expand TReg cells as a method of immuno-surveillance avoidance. In an in vitro model, CD4+CD25-FoxP3- T-cells co-cultured with malignant plasma cells (primary MM cells and cell lines) induced a significant generation of CD4+CD25+FoxP3+ inducible TReg cells (tTReg cells; p<0.0001), in a contact-dependent manner. tTReg cells were polyclonal, demonstrated a suppressive phenotype and phenotypically, demonstrated increased FoxP3 (p = 0.0001), increased GITR (p<0.0001), increased PD1 (p = 0.003) and decreased CD62L (p = 0.007) expression compared with naturally occurring TReg cells. FACS-sorted tTReg cells differentiated into FoxP+IL-17+ and FoxP3-IL-17+ CD4+ cells upon TCR-mediated stimulation. Blocking experiments with anti-ICOS-L MoAb resulted in a significant inhibition of tTReg cell generation whereas both IL-10 & TGFβ blockade did not. MM tumour cells can directly generate functional TReg cells in a contact-dependent manner, mediated by ICOS/ICOS-L. These features suggest that tumour generation of TReg cells may contribute to evasion of immune surveillance by the host
Broad Down, Devon: archaeological and other stories
publication-status: PublishedThis is a post-print, author-produced version of an article accepted for publication
Journal of Material Culture, 2010, Vol. 15, Issue 3, pp. 345 - 367. Copyright © 2010 SAGE Publications. The definitive publisher-authenticated version is available online at http://mcu.sagepub.com/content/15/3/345.shortThis article explores the knowledge construction process of an archaeological site in East Devon, UK. Bouncing off an oral historical account of the site that seems to run against scientific truth claims, the author investigates the story of how knowledge of the site has developed over the last two centuries. Building on previous work that explores the history and practice of archaeology, the article opens up questions of what counts as evidence. Then, taking a cue from more recent work that suggests a more dynamic and open-ended engagement with the landscape, the article turns to examine how the meaning of a site can be made and remade. As part of this endeavour, questions of what as well as who can ‘speak’ are examined and some space is opened up for the agency of ‘minor figures’, both human and non-human

Prioritising actions for improving classroom air quality based on the analytic hierarchy process: case studies in China and the UK
The air quality in classrooms significantly impacts school children’s health and learning performance. It has been reported worldwide that classroom air quality does not meet the required standard and actions are pledged for improvement. However, it poses a challenge for decision-making in terms of prioritising taking-up measures. The aim of this study is to propose a method of identifying the action measures for improving classroom air quality and prioritising them. Case studies in the UK and China were conducted, and the key measures were identified through literature studies, open-ended questionnaire surveys,
and workshop discussions, which are classified into three categories: B1, policy; B2, technology; and B3, information sharing.
The analytical hierarchy process (AHP) is applied in the prioritisation of the action measures. A total of 138 teachers and parents from China and the UK participated in this case study. The genetic algorithm-optimised Hadamard product (GAOHP) method is applied to justify the consistency ratio (CR) within the required threshold value in order to ensure the consistency of the subjective perception and the accuracy of comparative weights. The results show that item B2, technology, is the most desired measure by both Chinese and British parents and teachers, despite the deviation from the optimal choice in China and the UK. Among the proposed action measures, the UK respondents strongly expected air purifiers with natural ventilation as opposed to their Chinese counterparts preferring to share the real-time status of classroom air quality. Our work will provide
strong support for the subsequent selection of indoor air quality improvement strategies for schools
Health effects of indoor air quality on children and young people
Air pollution is the environmental public health problem of our time. The United Nations Convention on the Rights of the Child sets out clear guidance to protecting the rights of children and young people, including a child's right to the best possible health (Article 24) and the right to a good standard of living. Unicef also consider that clean air is a right for all children. The UK Royal Medical Colleges vigorously advocate for a healthy environment at the population level and in local communities, especially where socio-economic circumstances limit the choice of where people can live, and which school children attend. Despite substantial progress in understanding outdoor air pollution, the potential risk to health, especially that of children and young people, from the indoor air has been largely overlooked, yet in modern times, the indoor environment has never been more important as lockdown with the Covi-19 virus pandemic has shown us. Here we provide an abridged version of the RCPCH/RCP Report The inside story: Health effects of indoor air quality on children and young people but without the section on recommendations. The full Report along with recommendations, released on 28 January 2020, can be accessed at https://www.rcpch.ac.uk/resources/inside-story-health-effects-indoor-air-quality-children-young-people. While we recognise that some aspects of this commentary are UK specific, much of the content has wide implication
Detailed Chemical Abundances of Four Stars in the Unusual Globular Cluster, Palomar 1
Detailed chemical abundances for twenty one elements are presented for four
red giants in the anomalous outer halo globular cluster Palomar 1 ( kpc, kpc) using high-resolution (R=36000) spectra from the High
Dispersion Spectrograph (HDS) on the Subaru Telescope. Pal 1 has long been
considered unusual because of its low surface brightness, sparse red giant
branch, young age, and its possible association with two extragalactic streams
of stars---this paper shows that its chemistry further confirms its unusual
nature. The mean metallicity of the four stars, ,
is high for a globular cluster so far from the Galactic center, but is low for
a typical open cluster. The [/Fe] ratios, though in agreement with the
Galactic stars within the errors, agree best with the lower values in
dwarf galaxies. No signs of the Na/O anticorrelation are detected in Pal 1,
though Na appears to be marginally high in all four stars. Pal 1's neutron
capture elements are also unusual: its high [Ba/Y] ratio agrees best with dwarf
galaxies, implying an excess of second-peak over first-peak s-process elements,
while its [Eu/] and [Ba/Eu] ratios show that Pal 1's contributions from
the r-process must have differed in some way from normal Galactic stars.
Therefore, Pal 1 is chemically unusual, as well in its other properties. Pal 1
shares some of its unusual abundance characteristics with the young clusters
associated with the Sagittarius dwarf galaxy remnant and the intermediate-age
LMC clusters, and could be chemically associated with the Canis Majoris
overdensity; however it does not seem to be similar to the Monoceros/Galactic
Anticenter Stellar Stream.Comment: 24 pages, 25 figures; to appear in the Astrophysical Journa
