    ARIA 2016: Care pathways implementing emerging technologies for predictive medicine in rhinitis and asthma across the life cycle
    (2016) Bousquet, J; Hellings, P W; Agache, I; Bedbrook, A; Bachert, C; Bergmann, K C; Bewick, M; Bindslev-Jensen, C; Bosnic-Anticevitch, S; Bucca, C; Caimmi, D P; Camargos, P A M; Canonica, G W; Casale, T; Chavannes, N H; Cruz, A A; De Carlo, G; Dahl, R; Demoly, P; Devillier, P; Fonseca, J; Fokkens, W J; Guldemond, N A; Haahtela, T; Illario, M; Just, J; Keil, T; Klimek, L; Kuna, P; Larenas-Linnemann, D; Morais-Almeida, M; Mullol, J
    Abstract The Allergic Rhinitis and its Impact on Asthma (ARIA) initiative commenced during a World Health Organization workshop in 1999. The initial goals were (1) to propose a new allergic rhinitis classification, (2) to promote the concept of multi-morbidity in asthma and rhinitis and (3) to develop guidelines with all stakeholders that could be used globally for all countries and populations. ARIA—disseminated and implemented in over 70 countries globally—is now focusing on the implementation of emerging technologies for individualized and predictive medicine. MASK [MACVIA (Contre les Maladies Chroniques pour un Vieillissement Actif)-ARIA Sentinel NetworK] uses mobile technology to develop care pathways for the management of rhinitis and asthma by a multi-disciplinary group and by patients themselves. An app (Android and iOS) is available in 20 countries and 15 languages. It uses a visual analogue scale to assess symptom control and work productivity as well as a clinical decision support system. It is associated with an inter-operable tablet for physicians and other health care professionals. The scaling up strategy uses the recommendations of the European Innovation Partnership on Active and Healthy Ageing. The aim of the novel ARIA approach is to provide an active and healthy life to rhinitis sufferers, whatever their age, sex or socio-economic status, in order to reduce health and social inequalities incurred by the disease.

    Early maternal mirroring predicts infant motor system activation during facial expression observation
    (2017) Rayson, Holly; Bonaiuto, James John; Ferrari, Pier Francesco; Murray, Lynne
    Processing facial expressions is an essential component of social interaction, especially for preverbal infants. In human adults and monkeys, this process involves the motor system, with a neural matching mechanism believed to couple self- and other-generated facial gestures. Here, we used electroencephalography to demonstrate recruitment of the human motor system during observation and execution of facial expressions in nine-month-old infants, implicating this system in facial expression processing from a very young age. Notably, examination of early video-recorded mother-infant interactions supported the common, but as yet untested, hypothesis that maternal mirroring of infant facial gestures is central to the development of a neural matching mechanism for these gestures. Specifically, the extent to which mothers mirrored infant facial expressions at two months postpartum predicted infant motor system activity during observation of the same expressions at nine months. This suggests that maternal mirroring strengthens mappings between visual and motor representations of facial gestures, which increases infant neural sensitivity to particularly relevant cues in the early social environment.

    Evolution of the hypoxia-sensitive cells involved in amniote respiratory reflexes
    (2017) Hockman, Dorit; Burns, Alan J; Schlosser, Gerhard; Gates, Keith P; Jevans, Benjamin; Mongera, Alessandro; Fisher, Shannon; Unlu, Gokhan; Knapik, Ela W; Kaufman, Charles K; Mosimann, Christian; Zon, Leonard I; Lancman, Joseph J; Dong, P Duc S; Lickert, Heiko; Tucker, Abigail S; Baker, Clare V H
    The evolutionary origins of the hypoxia-sensitive cells that trigger amniote respiratory reflexes – carotid body glomus cells, and ‘pulmonary neuroendocrine cells’ (PNECs) - are obscure. Homology has been proposed between glomus cells, which are neural crest-derived, and the hypoxia-sensitive ‘neuroepithelial cells’ (NECs) of fish gills, whose embryonic origin is unknown. NECs have also been likened to PNECs, which differentiate in situ within lung airway epithelia. Using genetic lineage-tracing and neural crest-deficient mutants in zebrafish, and physical fate-mapping in frog and lamprey, we find that NECs are not neural crest-derived, but endoderm-derived, like PNECs, whose endodermal origin we confirm. We discover neural crest-derived catecholaminergic cells associated with zebrafish pharyngeal arch blood vessels, and propose a new model for amniote hypoxia-sensitive cell evolution: endoderm-derived NECs were retained as PNECs, while the carotid body evolved via the aggregation of neural crest-derived catecholaminergic (chromaffin) cells already associated with blood vessels in anamniote pharyngeal arches.

    Exploring the uptake and integration of emerging technology into pedagogical practices in Health Sciences Education using an activity systems approach
    (2025) Doyle, Gregory; Ng'ambi, Dickson
    This study investigates integrating educational technology into pedagogy and the role of professional development within a Health Sciences Faculty. It is framed within the interpretivist paradigm and informed by Cultural-Historical Activity Theory (CHAT) and Technological Pedagogical Content Knowledge (TPACK). A systematic literature review followed PRISMA 2020 guidelines to ensure study selection and reporting transparency. The overarching question of why particular lecturers, referred to as BrightSparks, excel in educational technology integration and how they might influence professional development is investigated. Integrating educational technologies in health sciences, with a focus on innovation, remains a challenge for most lecturers. This study defines innovation as the transformative and pedagogically grounded integration of technology to enhance teaching and learning. Hence, this research explores the strategies, challenges, and contextual factors that shape successful educational technology adoption and integration. A sequential mixed methods approach was adopted, with the quantitative component using a Likert-scale online survey and the qualitative component using semi-structured online interviews. Participants were selected based on specific characteristics, particularly their proficiency in using educational technology and identification as potential BrightSparks. Among the 29 participants, 814 professional development activities were attended during the 12 months preceding filling in the survey, with individual attendance ranging from 0 to 60 and an average of about 28 activities per participant. Spearman's rank correlation and the Mann-Whitney U Test examined relationships between scores, demographic characteristics, and formal qualifications. Correlations emerged between academic qualification, teaching experience, and autonomy. The qualitative interviews revealed nuanced social and cultural dynamics influencing educational technology integration. Deductive thematic analysis using CHAT and TPACK, emphasising CHAT as the central framework for analysing BrightSparks' practices, illuminated the complexities of integrating educational technology, pedagogy, and content knowledge and identified contradictions affecting professional development. The combined quantitative and qualitative data derived from BrightSparks emphasised adaptability, agency, student-centredness, transformative pedagogical approaches, and institutional support, corroborated by literature in the field. These findings informed the development of a ‘bottom-up' Knowledge Framework for Technology Transformation (KF4TT), integrating the strengths of CHAT and TPACK to support educational technology integration through professional development in higher education. Essential components of the KF4TT include targeted professional development to enhance individual lecturers' TPACK competencies, institutional support, collaborative learning communities, strategies to address systemic barriers, and encouragement of lecturer agency to foster ownership and flexibility in using professional development. In contrast to traditional professional development models, flexibility, adaptability, and sustainability are key features of the KF4TT, enabling individual lecturers and institutional leaders to continuously review and adapt to rapidly changing educational technology in higher education.

    Genome-wide DNA methylation in mixed ancestry individuals with diabetes and prediabetes from South Africa
    (2016) Matsha, Tandi E; Pheiffer, Carmen; Humphries, Stephen E; Gamieldien, Junaid; Erasmus, Rajiv T; Kengne, Andre P
    Aims. To conduct a genome-wide DNA methylation in individuals with type 2 diabetes, individuals with prediabetes, and control mixed ancestry individuals from South Africa. Methods. We used peripheral blood to perform genome-wide DNA methylation analysis in 3 individuals with screen detected diabetes, 3 individuals with prediabetes, and 3 individuals with normoglycaemia from the Bellville South Community, Cape Town, South Africa, who were age-, gender-, body mass index-, and duration of residency-matched. Methylated DNA immunoprecipitation (MeDIP) was performed by Arraystar Inc. (Rockville, MD, USA). Results. Hypermethylated DMRs were 1160 (81.97%) and 124 (43.20%), respectively, in individuals with diabetes and prediabetes when both were compared to subjects with normoglycaemia. Our data shows that genes related to the immune system, signal transduction, glucose transport, and pancreas development have altered DNA methylation in subjects with prediabetes and diabetes. Pathway analysis based on the functional analysis mapping of genes to KEGG pathways suggested that the linoleic acid metabolism and arachidonic acid metabolism pathways are hypomethylated in prediabetes and diabetes. Conclusions. Our study suggests that epigenetic changes are likely to be an early process that occurs before the onset of overt diabetes. Detailed analysis of DMRs that shows gradual methylation differences from control versus prediabetes to prediabetes versus diabetes in a larger sample size is required to confirm these findings.

    Searches for exclusively produced W boson pairs in the process p p ( γ γ ) → p W + W - p and an exclusively produced Higgs boson in the process p p ( g g ) → p H p have been performed using e ± μ ∓ final states. These measurements use 20.2 fb - 1 of p p collisions collected by the ATLAS experiment at a center-of-mass energy √ s = 8 TeV at the LHC. Exclusive production of W + W - consistent with the Standard Model prediction is found with 3.0 σ significance. The exclusive W + W - production cross section is determined to be σ ( γ γ → W + W - → e ± μ ∓ X ) = 6.9 ± 2.2 ( stat ) ± 1.4 ( sys ) fb , in agreement with the Standard Model prediction. Limits on anomalous quartic gauge couplings are set at 95% confidence level as - 1.7 × 10 - 6 < a W 0 / Λ 2 < 1.7 × 10 - 6 GeV - 2 and - 6.4 × 10 - 6 < a W C / Λ 2 < 6.3more » × 10 - 6 GeV - 2 . A 95% confidence-level upper limit on the total production cross section for an exclusive Higgs boson is set to 1.2 pb.« less

    Here, inclusive isolated-photon production in pp collisions at a centre-of-mass energy of 13TeV is studied with the ATLAS detector at the LHC using a data set with an integrated luminosity of 3.2fb -1. The cross section is measured as a function of the photon transverse energy above 125GeV in different regions of photon pseudorapidity. Next-to-leading-order perturbative QCD and Monte Carlo event-generator predictions are compared to the cross-section measurements and provide an adequate description of the data.

    A measurement of the total $pp$ cross section at the LHC at $sqrt{s}=8$ TeV is presented. An integrated luminosity of $500$ $mu$b${-1}$ was accumulated in a special run with high-$beta{star}$ beam optics to measure the differential elastic cross section as a function of the Mandelstam momentum transfer variable $t$. The measurement is performed with the ALFA sub-detector of ATLAS. Using a fit to the differential elastic cross section in the $-t$ range from $0.014$ GeV$2$ to $0.1$ GeV$2$ to extrapolate $trightarrow 0$, the total cross section, $sigma_{mathrm{tot}}(pprightarrow X)$, is measured via the optical theorem to be: $sigma_{mathrm{tot}}(pprightarrow X) = {96.07} ; pm 0.18 ; ({{stat.}}) pm 0.85 ; ({{exp.}}) pm 0.31 ; ({extr.}) ; {mb} ;,$ where the first error is statistical, the second accounts for all experimental systematic uncertainties and the last is related to uncertainties in the extrapolation $trightarrow 0$. In addition, the slope of the exponential function describing the elastic cross section at small $t$ is determined to be $B = 19.74 pm 0.05 ; ({{stat.}}) pm 0.23 ; ({{syst.}}) ; {GeV}{-2}$.

    Measurements of charge and CP asymmetries in b-hadron decays using top-quark events collected by the ATLAS detector in pp collisions at √s = 8 TeV

    Same- and opposite-sign charge asymmetries are measured in lepton+jets $tbar{t}$ events in which a $b$-hadron decays semileptonically to a soft muon, using data corresponding to an integrated luminosity of 20.3 fb${-1}$ from proton-proton collisions at a centre-of-mass energy of $sqrt{s}=8$ TeV collected with the ATLAS detector at the Large Hadron Collider at CERN. The charge asymmetries are based on the charge of the lepton from the top-quark decay and the charge of the soft muon from the semileptonic decay of a $b$-hadron and are measured in a fiducial region corresponding to the experimental acceptance. Four $CP$ asymmetries (one mixing and three direct) are measured and are found to be compatible with zero and consistent with the Standard Model.

    Measurements of top-quark pair to Z-boson cross-section ratios at √s = 13, 8, 7 TeV with the ATLAS detector

    Ratios of top-quark pair to Z-boson cross sections measured from protonproton collisions at the LHC centre-of-mass energies of √ s = 13 TeV, 8 TeV, and 7 TeV are presented by the ATLAS Collaboration. Single ratios, at a given √ s for the two processes and at different √ s for each process, as well as double ratios of the two processes at different √ s, are evaluated. The ratios are constructed using previously published ATLAS measurements of the tt¯ and Z-boson production cross sections, corrected to a common phase space where required, and a new analysis of Z → ` +` − where ` = e, µ at √ s = 13 TeV performed with data collected in 2015 with an integrated luminosity of 3.2 fb−1 . Correlations of systematic uncertainties are taken into account when evaluating the uncertainties in the ratios. The correlation model is also used to evaluate the combined cross section of the Z → e +e − and the Z → µ +µ − channels for each √ s value. The results are compared to calculations performed at next-to-next-to-leading-order accuracy using recent sets of parton distribution functions. The data demonstrate significant power to constrain the gluon distribution function for the Bjorken-x values near 0.1 and the lightquark sea for x < 0.02.

    Multisegment rupture in the 11 July 1889 Chilik earthquake ( M w 8.0-8.3), Kazakh Tien Shan, interpreted from remote sensing, field survey, and paleoseismic trenching: THE M w 8.0-8.3 CHILIK EARTHQUAKE
    (2016) Abdrakhmatov, K E; Walker, R T; Campbell, G E; Carr, A S; Elliott, A; Hillemann, C; Hollingsworth, J; Landgraf, A; Mackenzie, D; Mukambayev, A; Rizza, M; Sloan, R A
    The 11 July 1889 Chilik earthquake (M-w 8.0-8.3) forms part of a remarkable sequence of large earthquakes in the late nineteenth and early twentieth centuries in the northern Tien Shan. Despite its importance, the source of the 1889 earthquake remains unknown, though the macroseismic epicenter is sited in the Chilik valley, similar to 100 km southeast of Almaty, Kazakhstan (similar to 2 million population). Several short fault segments that have been inferred to have ruptured in 1889 are too short on their own to account for the estimated magnitude. In this paper we perform detailed surveying and trenching of the similar to 30 km long Saty fault, one of the previously inferred sources, and find that it was formed in a single earthquake within the last 700 years, involving surface slip of up to 10 m. The scarp-forming event, likely to be the 1889 earthquake, was the only surface-rupturing event for at least 5000 years and potentially for much longer. From satellite imagery we extend the mapped length of fresh scarps within the 1889 epicentral zone to a total of similar to 175 km, which we also suggest as candidate ruptures from the 1889 earthquake. The 175 km of rupture involves conjugate oblique left-lateral and right-lateral slip on three separate faults, with step overs of several kilometers between them. All three faults were essentially invisible in the Holocene geomorphology prior to the last slip. The recurrence interval between large earthquakes on any of these faults, and presumably on other faults of the Tien Shan, may be longer than the timescale over which the landscape is reset, providing a challenge for delineating sources of future hazard.

    No Evidence for Extensions to the Standard Cosmological Model
    (2017) Heavens, Alan; FANTAYE, YABEBAL; Sellentin, Elena; Eggers, Hans; Hosenie, Zafiirah; Kroon, Steve; Mootoovaloo, Arrykrishna
    We compute the Bayesian Evidence for models considered in the main analysis of Planck cosmic microwave background data. By utilising carefully-defined nearest-neighbour distances in parameter space, we reuse the Monte Carlo Markov Chains already produced for parameter inference to compute Bayes factors $B$ for many different model-dataset combinations. Standard 6-parameter flat $Lambda$CDM model is favoured over all other models considered, with curvature being mildly favoured only when CMB lensing is not included. Many alternative models are strongly disfavoured by the data, including primordial correlated isocurvature models ($ln B-7.8$), non-zero scalar-to-tensor ratio ($ln B-4.3$), running of the spectral index ($ln B = -4.7$), curvature ($ln B-3.6$), non-standard numbers of neutrinos ($ln B-3.1$), non-standard neutrino masses ($ln B-3.2$), non-standard lensing potential ($ln B-4.6$), evolving dark energy ($ln B-3.2$), sterile neutrinos ($ln B-6.9$), and extra sterile neutrinos with a non-zero scalar-to-tensor ratio ($ln B-10.8$). Other models are less strongly disfavoured with respect to flat $Lambda$CDM. As with all analyses based on Bayesian Evidence, the final numbers depend on the widths of the parameter priors. We adopt the priors used in the Planck analysis, while performing a prior sensitivity analysis. Our quantitative conclusion is that extensions beyond the standard cosmological model are disfavoured by Planck data. Only when newer Hubble constant measurements are included does $Lambda$CDM become disfavoured, and only mildly, compared with a dynamical dark energy model ($ln Bsim +2$).

    Overdensities of SMGs around WISE-selected, ultraluminous, high-redshift AGNs

    We investigate extremely luminous dusty galaxies in the environments around Wide-field Infrared Survey Explorer (WISE)-selected hot dust-obscured galaxies (Hot DOGs) and WISE/radio-selected active galactic nuclei (AGNs) at average redshifts of z = 2.7 and 1.7, respectively. Previous observations have detected overdensities of companion submillimetre-selected sources around 10 Hot DOGs and 30 WISE/radio AGNs, with overdensities of similar to 2-3 and similar to 5-6, respectively. We find that the space densities in both samples to be overdense compared to normal star-forming galaxies and submillimetre galaxies (SMGs) in the Submillimetre Common-User Bolometer Array 2 (SCUBA-2) Cosmology Legacy Survey (S2CLS). Both samples of companion sources have consistent mid-infrared (mid-IR) colours and mid-IR to submm ratios as SMGs. The brighter population around WISE/radio AGNs could be responsible for the higher overdensity reported. We also find that the star formation rate densities are higher than the field, but consistent with clusters of dusty galaxies. WISE-selected AGNs appear to be good signposts for protoclusters at high redshift on arcmin scales. The results reported here provide an upper limit to the strength of angular clustering using the two-point correlation function. Monte Carlo simulations show no angular correlation, which could indicate protoclusters on scales larger than the SCUBA-2 1.5-arcmin scale maps.

    This Letter presents a search for new resonances with mass larger than 250 GeV, decaying to a Z boson and a photon. The dataset consists of an integrated luminosity of 3.2 fb−1 of pp collisions collected at √s = 13 TeV with the ATLAS detector at the Large Hadron Collider. The Z bosons are identified through their decays either to charged, light, lepton pairs (e+e−, μ+μ−) or to hadrons. The data are found to be consistent with the expected background in the whole mass range investigated and upper limits are set on the production cross section times decay branching ratio to Zγ of a narrow scalar boson with mass between 250 GeV and 2.75 TeV.

    Search for metastable heavy charged particles with large ionization energy loss in p p collisions at s = 13     TeV using the ATLAS experiment

    This paper presents a search for massive charged long-lived particles produced in pp collisions at [sqrt]s=13 TeV at the LHC using the ATLAS experiment. The data set used corresponds to an integrated luminosity of 3.2 fb-2. Many extensions of the Standard Model predict the existence of massive charged long-lived particles, such as R-hadrons. These massive particles are expected to be produced with a velocity significantly below the speed of light, and therefore to have a specific ionization higher than any Standard Model particle of unit charge at high momenta. The Pixel subsystem of the ATLAS detector is used to measure the ionization energy loss of reconstructed charged particles and to search for such highly ionizing particles. The search presented here has much greater sensitivity than a similar search performed using the ATLAS detector in the [sqrt]s=8 TeV data set, thanks to the increase in expected signal cross section due to the higher center-of-mass energy of collisions, to an upgraded detector with a new silicon layer close to the interaction point, and to analysis improvements. No significant deviation from Standard Model background expectations is observed, and lifetime-dependent upper limits on R-hadron production cross sections and masses are set. Gluino R-hadrons with lifetimes above 0.4 ns and decaying to qq plus a 100 GeV neutralino are excluded at the 95% confidence level, with lower mass limit ranging between 740 and 1590 GeV. In the case of stable R-hadrons the lower mass limit at the 95% confidence level is 1570 GeV.
