title: Performing geochronology in the anthropocene: multiple temporalities of North Atlantic foreshores

description: As a branch of geomorphology, geochronology determines the ages of sediment, fossils, and rocks, thereby assembling a geologic planetary history. As a geochronological dénouement, the proposed geological epoch of the Anthropocene may indicate the figural moment in geologic time when human activity inscribed itself into sediment across the planet. This dissertation offers an artist’s account of practice-as-research investigating how to perform geochronology in the Anthropocene along North Atlantic foreshores. As sites prone to the geologic acts of deposition, erosion, and intrusion, foreshores provide an impermanent surface on which to interrogate the deep time, hidden knowledges, and climate crisis affiliated with the Anthropocene’s inaugural narrative. Geochronologists partly comprising a working group to give the Anthropocene its formal designation note that “[t]he expression of the Anthropocene in the environmentally sensitive coastal systems [including beaches, tidal flats, and deltas]… represents a diverse patchwork of deposits and lacunae that reflect local interplays of natural and anthropogenic forces” (Zalasiewicz, Williams, and Waters 2014). Climate change also places foreshores as central players impacted by storminess, glacial melt, rising sea levels, and ocean acidification. Produced as the book Sound of Mull, the artist’s performance scores were developed through artistic practice-as-research and offer strategies for experiential knowledge acquisition through direct or imagined engagement with the multiple temporalities and more-than-human co-constituents of North Atlantic foreshores. Participatory, experiential engagement may sensitize people to the hidden geochronologies of everyday life. This dissertation is situated within an interdisciplinary practice-as-research methodology integral to geopoetics praxis, interweaving research from performance studies, geology, human geography, and archaeology. Detailing foreshore performances enacted in Denmark, Iceland, Norway, Scotland, and Sweden between 2015 and 2019, the dissertation argues for interdependence and circulation as necessary components defining geopoetics. The account expounds the importance of both interdisciplinary scholarship and artistic practice-as-research methodology in the exploration of geopoetics as transformative action. Research was undertaken through PhD study at the University of Glasgow from 2015 to 2019, supported by the Lord Kelvin / Adam Smith Scholarship.

description: Historically, educators in higher education (HE) were expected to educate, generate knowledge, and do community service. With some commentators arguing that an academic must ‘publish or perish’, the expectation to create knowledge through research became overemphasized. The concept is widespread in HE institutions around the world. It aids to keep staff, particularly those in universities, constantly engaged with relevant knowledge works in their fields of expertise. According to this viewpoint, research publications are the most important factor in determining whether an academic or an administrator gets employed, promoted, acknowledged, retained, or not hired. The idea of ‘publish or perish’, on the other hand, is based on the dominant Western knowledge creation realities, which largely misrepresent or ignore African realities. To avoid perpetuating inequalities in academia, it is critical to re-examine how this idea informs knowledge creation in Africa. For example, the enormous number of publications required for one to advance up the academic ladder comes at a hefty cost that is not always feasible to low-paid academics in Africa’s resource-poor countries. This limits promotion of some individuals. Basically, for many Africans, what matters is the information gained, not how many times one’s work is acknowledged in scholarly publications. We need to establish knowledge-creation processes that are tailored to African realities. To that goal, we must strike a balance between having numerous publications with the potential to have an impact on society, given that developing solutions to development concerns appears to be more vital for Africa right now. This paper problematizes the ‘publish or perish’ concept for African academics, especially those intending to make an impact in their society with a purpose of eliminating inequalities in academia.

description: The kagome-lattice crystal hosts various intriguing properties including the frustrated magnetism, charge order, topological state, superconductivity and correlated phenomena. To achieve high-performance kagome-lattice compounds for electronic and spintronic applications, careful tuning of the band structure would be desired. Here, the electronic structures of kagome-lattice crystal Ni3In2S2 were investigated by transport measurements, angle-resolved photoemission spectroscopy as well as ab initio calculations. The transport measurements reveal Ni3In2S2 as a compensated semimetal with record-high carrier mobility (~8683 cm2 V-1 S-1 and 7356 cm2 V-1 S-1 for holes and electrons) and extreme magnetoresistance (15518% at 2 K and 13 T) among kagome-lattice materials. These extraordinary properties are well explained by its band structure with indirect gap, small electron/hole pockets and large bandwidth of the 3d electrons of Ni on the kagome lattice. This work demonstrates that the crystal field and doping serve as the key tuning knobs to optimize the transport properties in kagome-lattice crystals. Our work provides material basis and optimization routes for kagome-lattice semimetals as electronics and spintronics applications.

description: We present a first-principles theory of dynamical spin excitations in the presence of spin-orbit coupling. The broken global spin rotational invariance leads to a new sum rule. We explore the competition between the magnetic anisotropy energy and the external magnetic field, as well as the role of electron-hole excitations, through calculations for 3$d$-metal adatoms on the Cu(111) surface. The spin excitation resonance energy and lifetime display non-trivial behavior, establishing the strong impact of relativistic effects. We legitimate the use of the Landau-Lifshitz-Gilbert equation down to the atomic limit, but with parameters that differ from a stationary theory.

description: The availability of highly effective CFTR modulators is revolutionizing the treatment of cystic fibrosis (CF) and drastically improving outcomes. MRI-based imaging modalities are now emerging as highly sensitive endpoints, particularly in the setting of mild lung disease. Adult CF patients were recruited from a single center prior to starting treatment with E/T/I. The following studies were obtained before and after one month on treatment: spirometry, multiple breath nitrogen washout (MBW), 1H UTE MRI (structural images) and 19F MRI (ventilation images). Changes between visits were calculated, as were correlations between FEV1, lung clearance index (LCI), MRI structural scores, and MRI-based ventilation descriptors. Eight subjects had complete datasets for evaluation. Consistent with prior clinical trials, FEV1 and LCI improved after 28 days of E/T/I use. 1H UTE MRI detected improvements in bronchiectasis/airway wall thickening score and mucus plugging score after 28 days of therapy. 19F MRI demonstrated improvements in fractional lung volume with slow gas washout time (FLV↑tau2) and ventilation defect percentage (VDP). Improvements in FLV↑tau2 and VDP correlated with improvement in FEV1 (r = 0.81 and 0.86, respectively, p < 0.05). This observational study establishes the ability of 19F MRI and 1H UTE MRI to detect improvements in lung structure and function after E/T/I treatment. This study supports further development of 19F MRI and 1H UTE MRI as outcome measures for cystic fibrosis research and drug development.

description: Wave propagation in nonlinear theories of the electromagnetism described by Lagrangian densities dependent upon its two local invariants L(F, G) is revisited. On the light of the recent findings in metamaterials, it is here shown that trirefringence is also a possible phenomenon to occur in the realm of such nonlinear theories. A specific model exhibiting this effect is investigated both in terms of phase and group velocities. It is claimed that wave propagation in some well known nonlinear models for spin-one fields, like QED and QCD in certain regimes, may exhibit trirefringence.

Resting-State Functional MRI Adaptation with Attention Graph Convolution Network for Brain Disorder Identification

description: Multi-site resting-state functional magnetic resonance imaging (rs-fMRI) data can facilitate learning-based approaches to train reliable models on more data. However, significant data heterogeneity between imaging sites, caused by different scanners or protocols, can negatively impact the generalization ability of learned models. In addition, previous studies have shown that graph convolution neural networks (GCNs) are effective in mining fMRI biomarkers. However, they generally ignore the potentially different contributions of brain regions- of-interest (ROIs) to automated disease diagnosis/prognosis. In this work, we propose a multi-site rs-fMRI adaptation framework with attention GCN (A2GCN) for brain disorder identification. Specifically, the proposed A2GCN consists of three major components: (1) a node representation learning module based on GCN to extract rs-fMRI features from functional connectivity networks, (2) a node attention mechanism module to capture the contributions of ROIs, and (3) a domain adaptation module to alleviate the differences in data distribution between sites through the constraint of mean absolute error and covariance. The A2GCN not only reduces data heterogeneity across sites, but also improves the interpretability of the learning algorithm by exploring important ROIs. Experimental results on the public ABIDE database demonstrate that our method achieves remarkable performance in fMRI-based recognition of autism spectrum disorders.

description: Since the emergence of graphene, we have seen several proposals for the realization of Landau lasers tunable over the terahertz frequency range. The hope was that the non-equidistance of the Landau levels from Dirac fermions would suppress the harmful non-radiative Auger recombination. Unfortunately, even with this non-equidistance an unfavorable non-radiative process persists in Landau-quantized graphene, and so far no cyclotron emission from Dirac fermions has been reported. One way to eliminate this last non-radiative process is to sufficiently modify the dispersion of the Landau levels by opening a small gap in the linear band structure. A proven example of such gapped graphene-like materials are HgTe quantum wells close to the topological phase transition. In this work, we experimentally demonstrate Landau emission from Dirac fermions in such HgTe quantum wells, where the emission is tunable by both the magnetic field and the carrier concentration. Consequently, these results represent an advance in the realization of terahertz Landau lasers tunable by magnetic field and gate-voltage.

description: We theoretically predict two new classes of three-dimensional topological crystalline insulators (TCIs), which have an odd number of unpinned surface Dirac cones protected by crystal symmetries. The first class is protected by a single glide plane symmetry; the second class is protected by a composition of a twofold rotation and time-reversal symmetry. Both classes of TCIs are characterized by a quantized $π$ Berry phase associated with surface states and a $Z_2$ topological invariant associated with the bulk bands. In the presence of disorder, these TCI surface states are protected against localization by the average crystal symmetries, and exhibit critical conductivity in the universality class of the quantum Hall plateau transition. These new TCIs exist in time-reversal-breaking systems with or without spin-orbital coupling, and their material realizations are discussed.

Crab Nebula: five-year observation with ARGO-YBJ

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: The ARGO-YBJ air shower detector monitored the Crab Nebula gamma ray emission from 2007 November to 2013 February. The integrated signal, consisting of $\sim$3.3 $\times$ 10$^5$ events,reached the statistical significance of 21.1 standard deviations. The obtained energy spectrum in the energy range 0.3-20 TeV can be described by a power law function dN/dE = I$_0$ (E / 2 TeV)$^{-α}$, with a flux normalization I$_0$ = (5.2 $\pm$ 0.2) $\times$ 10$^{-12}$ photons cm$^{-2}$ s$^{-1}$ TeV$^{-1}$ and $α$ = 2.63 $\pm$ 0.05, corresponding to an integrated flux above 1 TeV of 1.97 $\times$ 10$^{-11}$ photons cm$^{-2}$ s$^{-1}$. The systematic error is estimated to be less than 30$\%$ for the flux normalization and 0.06 for the spectral index. Assuming a power law spectrum with an exponential cutoff dN/dE = I$_0$ (E / 2 TeV)$^{-α}$ $\exp$ (-E / E$_{cut}$), the lower limit of the cutoff energy E$_{cut}$ is 12 TeV, at 90$\%$ confidence level. Our extended dataset allows the study of the TeV emission over long timescales. Over five years, the light curve of the Crab Nebula in 200-day bins is compatible with a steady emission with a probability of 7.3 $\times$ 10$^{-2}$. A correlated analysis with Fermi-LAT data over $\sim$4.5 years using the light curves of the two experiments gives a Pearson correlation coefficient $r$ = 0.56 $\pm$ 0.22. Concerning flux variations on timescales of days, a "blind" search for flares with a duration of 1-15 days gives no excess with a significance higher than four standard deviations. The average rate measured by ARGO-YBJ during the three most powerful flares detected by Fermi-LAT is 205 $\pm$ 91 photons day$^{-1}$, consistent with the average value of 137 $\pm$ 10 day$^{-1}$.

description: Climate change poses a cataclysmic threat to public health and human rights. Global
health is inextricably linked to planetary health, with a changing climate influencing the
conditions necessary for human health and safety while undermining a range of human
rights. International legal agreements to mitigate emissions—from the 1992 United Nations
Framework Convention on Climate Change (UNFCCC) through the 2015 Paris Agreement
and into the 2021 Glasgow Climate Pact—have faced limitations in ameliorating the public
health threats caused by the unfolding climate crisis. These inequitable health threats pose
sweeping implications for health-related human rights, especially in low- and middleincome
countries, with environmental degradation challenging the most fundamental
conditions for human life and the individual rights of the most vulnerable populations.
As public health concerns begin to be considered in climate change responses, human
rights can provide a legal path to support international mitigation efforts and health system
adaptation to address both the direct and indirect public health impacts of climate change.
This Special Issue of the International Journal of Environmental Research and Public Health
addresses the dynamic balance between global health and climate justice, bringing together
policy analysis and empirical research to examine the public health threats of climate change
and consider the human rights advancements necessary to frame policies for mitigation
and adaptation.

description: The Dzyaloshinskii-Moriya Interaction (DMI) between spins is induced by spin-orbit coupling in magnetic materials lacking inversion symmetry. DMI is recognized to play a crucial role at the interface between ferromagnetic (FM) and heavy nonmagnetic (NM) metals to create topological textures called magnetic skyrmions which are very attractive for ultra-dense information storage and spintronic devices. DMI also plays an essential role for fast domain wall (DW) dynamics driven by spin-orbit torques. Here, we present first principles calculations which clarify the main features and microscopic mechanisms of DMI in Co/Pt bilayers. DMI is found to be predominantly located at the interfacial Co layer, originating from spin-orbit energy provided by the adjacent NM layer. Furthermore, no direct correlation is found between DMI and proximity induced magnetism in Pt. These results clarify underlying mechanisms of DMI at FM/NM bilayers and should help optimizing material combinations for skyrmion- and DW-based storage and memory devices.

description: We report Very Large Array (VLA) observations in the Q-band toward 10 ionized jet candidates to search for SiO emission, a well-known shocked gas tracer. We detected 7 mm continuum counterparts toward 90% of the jet candidates. In most cases, the jet candidate is located toward the center of the 7 mm core, and the high masses ($\approx 100\,M_\odot$) and densities ($\approx 10^7\, \text{cm}^{-3}$) of the cores suggest that the central objects are very young high-mass protostars. We detected SiO $J=1-0$ emission associated with 6 target sources. In all cases, the morphology and spectrum of the emission is consistent with what is expected for molecular jets along an outflow axis, thus confirming the jet nature of 60% of our sample. Our data suggest a positive correlation between the SiO luminosity $L_{SiO}$, and both the bolometric luminosity $L_{Bol}$ and the radio luminosity $S_νd^2$ of the driving sources.

description: We explore the problems of classification of composite object (images, speech signals) with low number of models per class. We study the question of improving recognition performance for medium-sized database (thousands of classes). The key issue of fast approximate nearest-neighbor methods widely applied in this task is their heuristic nature. It is possible to strongly prove their efficiency by using the theory of algorithms only for simple similarity measures and artificially generated tasks. On the contrary, in this paper we propose an alternative, statistically optimal greedy algorithm. At each step of this algorithm joint density (likelihood) of distances to previously checked models is estimated for each class. The next model to check is selected from the class with the maximal likelihood. The latter is estimated based on the asymptotic properties of the Kullback-Leibler information discrimination and mathematical model of piecewise-regular object with distribution of each regular segment of exponential type. Experimental results in face recognition for FERET dataset prove that the proposed method is much more effective than not only brute force and the baseline (directed enumeration method) but also approximate nearest neighbor methods from FLANN and NonMetricSpaceLib libraries (randomized kd-tree, composite index, perm-sort).

description: RNA is a fundamental class of biomolecules that mediate a large variety of molecular processes within the cell. Computational algorithms can be of great help in the understanding of RNA structure-function relationship. One of the main challenges in this field is the development of structure-prediction algorithms, which aim at the prediction of the three-dimensional (3D) native fold from the sole knowledge of the sequence. In a recent paper, we have introduced a scoring function for RNA structure prediction. Here, we analyze in detail the performance of the method, we underline strengths and shortcomings, and we discuss the results with respect to state-of-the-art techniques. These observations provide a starting point for improving current methodologies, thus paving the way to the advances of more accurate approaches for RNA 3D structure prediction.

Antibiotic stewardship in the outpatient setting: treating common infections in the adult population
Creators: name: Thomas, Yasmine
Publisher: name: No Publisher Supplied
Year: 2019

description: The use and misuse of antibiotics is a major contributor to the development of antibiotic-resistant bacteria. Infections are among the most common reasons for outpatient visits, and the vast majority of antibiotic prescriptions occur in this setting. Many of these prescriptions however, are unnecessary, since they treat viral illnesses or other conditions that do not respond to antibiotics. Therefore, it is critical that clinicians practicing outpatient medicine be highly knowledgeable concerning the epidemiology, diagnosis, and management of commonly encountered infections. This quality improvement project was conducted at a Family Medicine practice in Northern New Jersey, and examined current management of common outpatient infections. Study participants received current adult treatment guidelines for upper respiratory infections (URIs), urinary tract infections (UTIs) and superficial skin infections (SSIs). In addition, participants completed an outpatient antibiotic continuing education module, received best practice advisory reminders, and had antibiotic stewardship flyers placed in their offices. Prescriptive patterns were measured using descriptive analysis and McNemar’s test. The results indicated the level of antibiotic stewardship in the outpatient setting remained low amongst all categories of providers for all categories of patients, and that an educational intervention that aimed to improve antibiotic stewardship did not significantly improve adherence to national clinical guidelines between 2017 and 2018 in adult outpatients diagnosed with upper respiratory infections, urinary tract infections and superficial skin infections.

description: Over the past two decades, the literature has shown a clear gradient between child health and wealth. The same health–wealth gradient is also observed among children in China, with a large gap in health between rural and urban children. However, there are still unanswered questions about the main causes of China’s rural–urban child health inequality. This paper aims to review the major factors that have led to the relatively poor levels of health among China’s rural children. In addition to the direct income effect on children’s health, children in rural areas face disadvantages compared with their urban counterparts from the beginning of life: Prenatal care and infant health outcomes are worse in rural areas; rural caregivers have poor health outcomes and lack knowledge and support to provide adequate nurturing care to young children; there are large disparities in access to quality health care between rural and urban areas; and rural families are more likely to lack access to clean water and sanitation. In order to inform policies that improve health outcomes for the poor, there is a critical need for research that identifies the causal drivers of health outcomes among children. Strengthening the pediatric training and workforce in rural areas is essential to delivering quality health care for rural children. Other potential interventions include addressing the health needs of mothers and grandparent caregivers, improving parenting knowledge and nurturing care, improving access to clean water and sanitation for remote families, and most importantly, targeting poverty itself.

description: This study is aimed at investigating the dynamic evolution of the orbits of stellar globular clusters (GCs). To integrate the orbits backward in time, the authors use models of the time-varying potentials derived from cosmological simulations, which are closest to the potential of the Galaxy. This allows for estimating the probability of close passages (collisions) of GCs with respect to each other and the Galactic center (GalC) in the Galaxy undergoing dynamic changes in the past. To reproduce the dynamics of the Galaxy in time, five potentials selected from the IllustrisTNG-100 large-scale cosmological database, which are similar in their characteristics to the current physical parameters of the Milky Way, are used. With these time-varying potentials, we have reproduced the orbital trajectories of 143 GCs 10 Gyr back in time using our original phi-GPU N-body code. Each GC was treated as a single physical particle with the assigned position and velocity of the cluster center from the Gaia DR2 observations. For each of the potentials, 1000 initial conditions were generated with randomized initial velocities of GCs within the errors of the observational data. In this study, we consider close passages to be passages with a relative distance of less than 100 pc and a relative speed of less than 250 km/s. To select clusters that pass at close distances from the GalC, the following criterion is applied based only on the relative distance: it must be less than 100 pc. Applying the above criteria, the authors obtained statistically significant rates of close passages of GCs with respect to each other and to the GalC. It has been determined that GCs during their evolution have approximately 10 intersecting trajectories with each other on the average and approximately 3 to 4 close passages near the GalC in 1 Gyr at a distance of 50 pc for each of the chosen potentials.

description: Eco-concern, the distress experienced relating to climate change, is associated with mental health, yet no study has examined disordered eating related to eco-concern. This study developed and validated a 10-item scale assessing Eating-Related Eco-Concern (EREC). Participants (n = 224) completed the EREC, Climate Change Worry Scale (CCWS), and Eating Disorder Examination-Questionnaire (EDE-Q). Construct validity, convergent validity, and internal consistency were evaluated. Sex differences in EREC were evaluated using t-tests. Associations among the EREC, CCWS, and EDE-Q were evaluated using linear regression models. Sensitivity analyses were conducted in individuals below EDE-Q global score clinical cut-offs. Factor analysis suggested that all items loaded adequately onto one factor. Pearson’s correlation and Bland–Altman analyses suggested strong correlation and acceptable agreement between the EREC and CCWS (r = 0.57), but weak correlation and low agreement with the EDE-Q global score (r = 0.14). The EREC had acceptable internal consistency (α = 0.88). No sex difference was observed in the EREC in the full sample; females had a significantly higher mean score than males in sensitivity analysis. The EREC was significantly positively associated with the CCWS and EDE-Q global and shape concern scores, but not in sensitivity analysis. The EREC is a brief, validated scale that can be useful to screen for eating-related eco-concern.

description: The availability of online biodiversity data has increased in recent decades, aiding our

understanding of diversity patterns and species richness–environment relationships

across temporal and spatial scales. However, even the most exhaustive databases are

prone to sampling biases, which create knowledge gaps in species distributions and

increase uncertainty in model predictions. Regarding marine environments, intertidal

zones are globally distributed and considered early warning systems for climate change

impacts and species’ range shifts. Owing to their relative accessibility, intertidal records

should – supposedly – be less incomplete and biased compared to open-ocean and

deep-sea areas. Yet, the extent and coverage of intertidal records available in global bio-

diversity databases remains unknown. In this study, we used a high-resolution world-

wide tidal flat map to identify intertidal records of 11 563 benthic species from the

OBIS (Ocean Biodiversity Information System) portal. Following a thorough data-

cleaning process, we evaluated geographic patterns in observed species richness, site

accessibility, sampling effort, and inventory completeness across latitudes. We demon-

strate that observed species richness has mid-latitudinal peaks while the tropics accu-

mulate species with missing records, similar to patterns described for the entire marine

realm. These patterns correlate with disproportionate mid-latitude sampling efforts

and poor tropical sampling coverage. Sixty-five percent of the mapped intertidal sites

are located within 3 hours of a city, but sampling records remain almost absent along

African Atlantic, South American Pacific, and Indo-Pacific coasts. Thus, even for the

accessible and well-studied intertidal shorelines, database records are not free from

geographical biases and their associated implications for biodiversity estimates. Our

results highlight the need for a better data-sharing culture, and we hope to encourage 

initiatives promoting more and better-distributed research efforts on intertidal biodiversity, which could improve global scale

detection and prediction of climate change impacts at regional and global scales.

description: We have investigated polycrystalline samples of the zigzag chain system BaTb$_2$O$_4$ with a combination of magnetic susceptibility, heat capacity, neutron powder diffraction, and muon spin relaxation measurements. Despite the onset of Tb$^{3+}$ short-range antiferromagnetic correlations at $|θ_{CW}|$ $=$ 18.5 K and a very large effective moment, our combined measurements indicate that BaTb$_2$O$_4$ remains paramagnetic down to 0.095 K. The magnetic properties of this material show striking similarities to the pyrochlore antiferromagnet Tb$_2$Ti$_2$O$_7$, and therefore we propose that BaTb$_2$O$_4$ is a new large moment spin liquid candidate.

title: Young onset dementia as experienced by family members
Creators: name: Regan, Daryl
Publisher: name: University of Glasgow
Year: 2020
Subjects: subject: Young onset dementia, partners' experiences, dementia.

description: Background: Young onset dementia (YOD) is estimated to make up around 5% of dementia diagnoses (Prince et al., 2014). Obtaining a diagnosis can be complex, with multiple diagnostic pathways. Partners of those with YOD are often involved; however, little is known about their experience of the pre-diagnostic phase from initial symptom recognition to diagnosis seeking. Aims: To explore partners’ experiences of the pre-diagnostic phase of YOD. Specifically, the study aimed to analyse how partners make sense of being involved in the process of seeking help from healthcare services. Method: The study utilised a retrospective qualitative design. Seven partners of individuals diagnosed with YOD within the last three years, were recruited from a community Young Onset Dementia Service within NHS Greater Glasgow & Clyde. Semi-structured interviews were transcribed verbatim and analysed using interpretative phenomenological analysis. Results: Three superordinate themes were identified from partners’ experiences: ‘changing relationship with partner’, ‘challenging relationship with healthcare services’ and ‘conflicted relationship with the diagnosis’. Conclusions: The findings provide valuable insights into partners’ experiences of the pre-diagnostic phase of YOD. Themes discussed offer healthcare providers factors to consider when designing and providing services for those with YOD and their partners. Further research exploring experiences of partners with different characteristics would be helpful in generating further knowledge to inform service development.
