description: We present results of magnetohydrodynamic (MHD) simulations of jet formation and propagation, discussing a variety of astrophysical setups. In the first approach we consider simulations of relativistic MHD jet formation, considering jets launched from the surface of a Keplerian disk, demonstrating numerically - for the first time - the self-collimating ability of relativistic MHD jets. We obtain Lorentz factors up to about 10 while acquiring a high degree of collimation of about 1 degree. We then present synchrotron maps calculated from the intrinsic jet structure derived from the MHD jet formation simulation. We finally present (non-relativistic) MHD simulations of jet lauching, treating the transition between accretion and ejection. These setups include a physical magnetic diffusivity which is essential for loading the accretion material onto the outflow. We find relatively high mass fluxes in the outflow, of the order of 20-40 % of the accretion rate.

Saliva Hypernatrium is a term developed by La Trobe University Public Health Palliative Care Unit Researchers (Dr. Lindsay Carey [Senior Research Fellow], Dr. Christa Carey-Sargeant [Speech Pathologist] and Lillian Krikheli [Speech Pathologist]) in Melbourne Australia (01 August 2019), to describe a seemingly rare medical condition of having excessive sodium within human saliva, that is not caused by another known condition (e.g., Sjogren syndrome, dehydration, hypersalivation, bacteria, nutritional deficiency, dry mouth, oral infection/oral bleeding, acid or bile reflux). A full report will be available via Research Online: http://hdl.handle.net/1959.9/568632.

ABSTRACT: Purpose: This scoping review explored the available peer-reviewed literature, plus medical/health information management records, case studies, expert opinions in the field of otolaryngology, and other relevant resources relating to the condition of idiopathic persistent and excessive salty tasting saliva, labelled by the authors as ‘Saliva Hypernatrium’. Method: An exploratory scoping review was conducted using the Arksey and O’Malley (2005) method to source key literature and other resources. Results: A total of 684 articles were initially identified using search terms derived from conditions relating to taste, salt and saliva. A total of 12 articles were found to be specifically relevant. Six key themes were discernible from the 12 articles which identified possible causes for salty saliva having no currently known medical cause. Discussion & Conclusion: This scoping review explored the available peer-reviewed literature, plus medical/health information management records, case studies, expert opinions in the field of otolaryngology, and other relevant resources relating to the condition of idiopathic persistent and excessive salty tasting saliva, labelled by the authors as ‘Saliva Hypernatrium’

description: This thesis comprises a systematic literature review, an empirical paper and a critical appraisal. A systematic review of quantitative studies examining the efficacy of cognitive interventions to improve decision-making in people with Mild Cognitive Impairment (MIC) was conducted. Twenty-six papers were identified. Results indicate that interventions to improve decision-making in people with MCI can be effective. Most studies tested interventions designed to improve higher-order thinking skills, or executive functions, that are thought to underpin decision-making. Of these, interventions targeting logical reasoning, cognitive control and inhibition demonstrated the best results. Risk of bias arising from poor quality research design or reporting affected most studies. Consequently, it was not possible to draw clear conclusions about the efficacy of particular interventions at this time. Implications and recommendations for research are discussed. The empirical paper explores the feasibility of using a capacity assessment tool designed to support remote working during the COVID-19 health crisis. Views were gathered from eight participants either through online focus groups or online individual interviews. Data from transcribed discussions, notes taken by a focus group assistant and notes from focus group debrief sessions between the researcher and focus group assistant were analysed using thematic analysis. Findings indicate that the tool is perceived to be feasible for use in practice and merits additional research. The assessment tool was praised for its structure and for prompts, questions and examples that enabled participants to obtain useful data in a pressurised context. Clinical implications are discussed and recommendations for research are outlined. The critical appraisal section offers reflections on the process of undertaking research into mental capacity and decision making. Ethical, philosophical and practical benefits and challenges are explored. The experience of undertaking research during a significant health crisis is examined and recommendations made for future applied research in these areas.

description: Convective dynamo simulations are performed in local Cartesian geometry. We report the first successful simulation of a large-scale oscillatory dynamo in rigidly rotating convection without stably stratified layers. A key requirement for exciting the large-scale dynamo is a sufficiently long integration time comparable to the ohmic diffusion time. By comparing two models with and without stably stratified layers, their effect on the large-scale dynamo is also studied. The spatiotemporal evolution of the large-scale magnetic field is similar in both models. However, it is intriguing that the magnetic cycle is much shorter in the model without the stable layer than with the stable layer. This suggests that the stable layer impedes the cyclic variations of the large-scale magnetic field.

description: Conjugation is the primary mechanism of horizontal gene transfer that spreads antibiotic resistance among bacteria. Although conjugation normally occurs in surface-associated growth (e.g., biofilms), it has been traditionally studied in well-mixed liquid cultures lacking spatial structure, which is known to affect many evolutionary and ecological processes. Here we visualize spatial patterns of gene transfer mediated by F plasmid conjugation in a colony of Escherichia coli growing on solid agar, and we develop a quantitative understanding by spatial extension of traditional mass-action models. We found that spatial structure suppresses conjugation in surface-associated growth because strong genetic drift leads to spatial isolation of donor and recipient cells, restricting conjugation to rare boundaries between donor and recipient strains. These results suggest that ecological strategies, such as enforcement of spatial structure and enhancement of genetic drift, could complement molecular strategies in slowing the spread of antibiotic resistance genes.

description: Dans notre thèse, nous étudions la période de « flottement » et de réorganisation du mouvement ouvrier entre le déclin de l’organisation des Chevaliers du Travail et l’ascension du syndicalisme catholique. Notre étude révèle que cette expérience de transition, entre les années 1896 et 1914, est formatrice pour le mouvement ouvrier de Québec et Lévis. L’analyse de ces années s’avère essentielle mieux saisir et caractériser la suite des évènements dans le monde syndical de cette région. Notre regard nouveau sur le mouvement ouvrier de Québec et Lévis permet d’éclairer le rôle actif des travailleurs et de nuancer le misérabilisme contenu dans une partie de l’historiographie ouvrière. En effet, nous montrons que les travailleurs de Québec et Lévis s’activent dans le monde du travail, mais aussi sur la scène politique, entre 1896 et 1914 afin d’améliorer leurs conditions de vie et de travail. Notre thèse indique aussi que, contrairement au contexte montréalais, Québec devient le bastion du syndicalisme national durant cette période. Cette conjecture peut trouver racine dans la relation particulière qui se développe à Québec et Lévis entre les patrons, la classe ouvrière et l’Église. En effet, l’Église de Québec et Lévis se montre un acteur important entre 1896 et 1914 ; la classe ouvrière doit ainsi négocier avec cette dernière pour se développer. Notre analyse permet ainsi d’expliquer le cheminement particulier des ouvriers de Québec et Lévis entre 1896 et 1914 et de mieux saisir leurs idéologies et leur conduite.

description: In this article we derive rigorously a nonlinear, steady, bifurcation through spectral bifurcation (i.e., eigenvalues of the linearized equation crossing the imaginary axis) for a class of hyperbolic-parabolic model in a strip. This is related to "cellular instabilities" occuring in detonation and MHD. Our results extend to multiple dimensions the results of Franz Achleitner and Peter Szmolyan (Saddle-node bifurcation of viscous profiles) on 1D steady bifurcation of viscous shock profiles; en passant, changing to an appropriate moving coordinate frame, we recover and somewhat sharpen results of Benjamin Texier and Kevin Zumbrun (Galloping instability of viscous shock waves) on transverse Hopf bifurcation, showing that the bifurcating time-periodic solution is in fact a spatially periodic traveling wave. Our technique consists of a Lyapunov-Schmidt type of reduction, which prepares the equations for the application of other bifurcation techniques. For the reduction in transverse modes, a general Fredholm Alternative-type result is derived, allowing us to overcome the unboundedness of the domain and the lack of compact embeddings; this result apply to general closed operators.

description: Anthropogenic stressors to freshwater environments have perpetuated water quality and quantity challenges for northern communities across Arctic Canada, making drinking water resources a primary concern for Arctic populations. To understand the ecological trajectory of freshwater supply sources, we conducted a paleolimnological assessment on two supplemental sources of freshwater in Igloolik, Nunavut, Canada. A stratigraphic examination of bioindicators (Insecta: Diptera: Chironomidae) allowed for paleotemperature reconstructions with decadal and centennial resolution over the past 2000 years. Between 200 and 1900 CE, the sub-fossil chironomid community was comprised of cold-water taxa, such as Abiskomyia, Micropsectra radialis-type, and Paracladius. Reconstructed temperatures were consistent with known climate anomalies during this period. A rapid shift in the composition of the chironomid community to warm-water adapted taxa (Chironomus anthracinus-type, Dicrotendipes, and Tanytarsus lugens-type) in the late 20th century was observed in both systems. Our results demonstrate that these lake ecosystems are undergoing marked transformations to warmer, more nutrient-rich environments, and suggest water sustainability pressures on freshwater and human systems will likely continue in tandem with ongoing climate change. To contextualize the influence of recent warming and elucidate the status of water resource vulnerability over the longer term, paleolimnological methods can be usefully applied as components of vulnerability assessments.

description: In this paper, we study the prospects for determining the nature of neutrinos in the context of a supersymmetric $B-L$ extension of the standard model by using dark matter indirect detection signals and bounds on $N_{\text{eff}}$ from the cosmic microwave background data. The model contains two new dark matter candidates whose dominant annihilation channels produce more neutrinos than neutralino dark matter in the minimal supersymmetric standard model. The photon and neutrino counts may then be used to discriminate between the two models. If the dark matter comes from the B-L sector, its indirect signals and impact on the cosmic microwave background can shed light on the nature of the neutrinos. When the light neutrinos are of Majorana type, the indirect neutrino signal from the Sun and the galactic center may show a prompt neutrino box-feature, as well as an earlier cut-off in both neutrino and gamma ray energy spectra. When the light neutrinos are of Dirac type, their contribution to the effective number of neutrinos $N_{\text{eff}}$ is at a detectable level.

description: Anisotropic mesh adaptation is studied for the linear finite element solution of eigenvalue problems with anisotropic diffusion operators. The M-uniform mesh approach is employed with which any nonuniform mesh is characterized mathematically as a uniform one in the metric specified by a metric tensor. Bounds on the error in the computed eigenvalues are established for quasi-M-uniform meshes. Numerical examples arising from the Laplace-Beltrami operator on parameterized surfaces, nonlinear diffusion, thermal diffusion in a magnetic field in plasma physics, and the Laplacian operator on an L-shape domain are presented. Numerical results show that anisotropic adaptive meshes can lead to more accurate computed eigenvalues than uniform or isotropic adaptive meshes. They also confirm the second order convergence of the error that is predicted by the theoretical analysis. The effects of approximation of curved boundaries on the computation of eigenvalue problems is also studied in two dimensions. It is shown that the initial mesh used to define the geometry of the physical domain should contain at least \sqrt{N} boundary points to keep the effects of boundary approximation at the level of the error of the finite element approximation, where N is the number of the elements in the final adaptive mesh. Only about N^{1/3} boundary points in the initial mesh are needed for boundary value problems. This implies that the computation of eigenvalue problems is more sensitive to the boundary approximation than that of boundary value problems.

description: The interplay of the tunneling transfer of charges and the emission and absorption of light can be investigated in a set-up, where a voltage-biased Josephson junction is placed in series to a microwave cavity. Here, we concentrate on the emission process and show that due to the inherent nonlinearity of the Josephson junction tunneling Cooper-pairs can create a variety of non-classical states of light. Depending on experimental parameters and tuning the device can be described by effective Hamiltonians, indicating specific photon creation mechanisms which lead to strongly bunched or anti-bunched light emission. We derive explicit analytical expressions for the photon correlation function $g^{(2)}(τ=0)$ for these different processes and investigate their full crossover numerically. Photon distribution functions show squeezing and other interesting non-Poissonian behavior.

titleType: Subtitle
Creators: name: Appleton, David
Publisher: name: Lancaster University

description: Mountain ecosystems are experiencing accelerated climate change and more frequent climatic extremes. Mountain soils play a critical role in local and regional biogeochemistry, while underpinning ecological stability and ecosystem multifunctionality. In the European Alps, mountain soils represent a critical carbon pool with the potential to modulate climate change through the sequestration of atmospheric carbon dioxide (CO2). However, climate warming may exacerbate soil carbon (C) and nitrous oxide (N2O) fluxes to the atmosphere. Consequently, European mountain ecosystems may become strong sources of atmospheric greenhouse gases, however, the environmental factors controlling the distribution of belowground C and N in mountain ecosystems and their relative importance across different spatial scales are largely unexplored. I aim to demonstrate that heterogeneity in the distribution of total soil C and N, and total organic C and N in microbial biomass, would occur with elevation and be augmented by microtopography. I explore elevation gradients stratified by life zone, underlying geology, parent material, vegetation composition and land-use type, differing only in proxy variables for microtopography. Heterogeneity in belowground C and N occurred with elevation and between sites of the same altitude for all transects. Slope angle was the most important topographic variable at lower elevations, likely due to the relationship with aboveground vegetation. Heterogeneity was constrained across the treeline ecotone, likely due to the overarching effect of declining temperature with increasing elevation on aboveground vegetation and second-order soil physicochemical drivers. The effect of slope was closely linked to response values at higher altitudes but was augmented by the effects of microtopography which became more pronounced with elevation. Overall, it emerged that the macro-scale effects of elevation-dependent factors may control belowground C and N in a general way, and site-specific conditions as a consequence of microtopographic and microclimatic dynamics may augment their heterogeneity at smaller scales.

description: We propose a scheme for generating atomic NOON states via adiabatic passage. In the scheme, a double $Λ$-type three-level atom is trapped in a bimodal cavity and two sets of $Λ$-type three-level atoms are translated into and outside of two single mode cavities respectively. The three cavities connected by optical fibres are always in vacuum states. After a series of operations and suitable interaction time, we can obtain arbitrary large-$n$ NOON states of two sets of $Λ$-type three-level atoms in distant cavities by performing a single projective measurement on the double $Λ$-type three-level atom. Due to adiabatic elimination of atomic excited states and the application of adiabatic passage, our scheme is robust against the spontaneous emissions of atoms, the decays of fibres and cavities photon leakage. So the scheme has a high fidelity and feasibility under the current available techniques.

The heuristic proposed in this paper attempts to map the tasks of an applications that are most related to each other in spiral manner and to find the best possible path load that minimizes the communication overhead. In this context, we have realized a simulation environment for experimental evaluations to map applications with varying number of tasks onto an 8x8 NoC-based Heterogeneous MPSoCs platform, we demonstrate that the new mapping heuristics with the new modified dijkstra routing algorithm proposed are capable of reducing the total execution time and energy consumption of applications when compared to state-of the-art run-time mapping heuristics reported in the literature.

I gained a new perspective of the world and an appreciation for my studies beyond anything I knew before, but although I felt it was the opportunity of a lifetime, I told myself I would never return.

The interaction is supposed to be small in the norm ·  ∞ but otherwise is very general, being possibly non-regular and non-Markovian. Our method consists in using the characterization of such diffusions as space-time Gibbs fields so that we construct them by space-time cluster expansions in the small coupling parameter.
One Bladelet at a Time. A Closer Look at the Aurignacian-style Artifacts from Heidesheim-Höllenberg, Germany
Creators: name: Anderson, Mark

description: The Heidesheim-Höllenberg surface site near Mainz, Germany has yielded a lithic assemblage containing both Middle and Upper Paleolithic tool types. Among the latter are a number of Aurignacian-style artifacts which include nosed and shouldered endscrapers, as well as a carinated burin with a possible stop-notch. Despite being surface finds, all types are almost certainly an integral part of a single cultural entity. In most cases, the Aurignacian-style artifacts are admittedly atypical and were not subject to any rigid standardization of manufacture. Given their often rudimentary appearance, it seems therefore somewhat of a paradox that they tend to resemble Recent Aurignacian forms, many of which are considered to be bladelet cores. Bladelet production in the assemblage is, however, only sporadic and, with a few exceptions, not associated with the Aurignacian-style artifacts.

description: We investigate electrostatic plasma instabilities of Farley-Buneman (FB) type driven by quasi-stationary neutral gas flows in the solar chromosphere. The role of these instabilities in the chromosphere is clarified. We find that the destabilizing ion thermal effect is highly reduced by the Coulomb collisions and can be ignored for the chromospheric FB-type instabilities. On the contrary, the destabilizing electron thermal effect is important and causes a significant reduction of the neutral drag velocity triggering the instability. The resulting threshold velocity is found as function of chromospheric height. Our results indicate that the FB type instabilities are still less efficient in the global chromospheric heating than the Joule dissipation of the currents driving these instabilities. This conclusion does not exclude the possibility that the FB type instabilities develop in the places where the cross-field currents overcome the threshold value and contribute to the heating locally. Typical length-scales of plasma density fluctuations produced by these instabilities are determined by the wavelengths of unstable modes, which are in the range $10-10^2$ cm in the lower chromosphere, and $10^2-10^3$ cm in the upper chromosphere. These results suggest that the decimetric radio waves undergoing scattering (scintillations) by these plasma irregularities can serve as a tool for remote probing of the solar chromosphere at different heights.

description: Pump-probe spectroscopy is central for exploring ultrafast dynamics of fundamental excitations, collective modes and energy transfer processes. Typically carried out using conventional diffraction-limited optics, pump-probe experiments inherently average over local chemical, compositional, and electronic inhomogeneities. Here we circumvent this deficiency and introduce pump-probe infrared spectroscopy with ~20 nm spatial resolution, far below the diffraction limit, which is accomplished using a scattering scanning near-field optical microscope (s-SNOM). This technique allows us to investigate exfoliated graphene single-layers on SiO2 at technologically significant mid-infrared (MIR) frequencies where the local optical conductivity becomes experimentally accessible through the excitation of surface plasmons via the s-SNOM tip. Optical pumping at near-infrared (NIR) frequencies prompts distinct changes in the plasmonic behavior on 200 femtosecond (fs) time scales. The origin of the pump-induced, enhanced plasmonic response is identified as an increase in the effective electron temperature up to several thousand Kelvin, as deduced directly from the Drude weight associated with the plasmonic resonances.

description: Three decades ago it became that the simple quark model approach for the proton failed in describing the spin structure — the spin contribution from quarks, as measured by the European Muon Collaboration (EMC), came out small, by far insufficient to explain the proton spin of 1/2. The experiment utilized the polarized muon beam from CERN’s SPS, which is naturally polarized originating from the weak decay of mainly pions. The EMC results triggered a wealth of activity trying to explain the “spin puzzle”, but also to confirm (or falsify) those findings.Already some twenty years early, it had been demonstrated that electrons in a storage ring will also be polarized — under certain conditions and in particular if waiting sufficiently long enough. The verification of this Sokolov-Ternov effect will be celebrated today in a different talk from this one. However, this talk will concentrate on how the Sokolov-Ternov effect got exploited in the East Hall of the HERA storage rings at DESY to study the spin structure of the proton. It took five hard years to convince DESY to host a spin experiment and in particular that it was feasible to achieve sizable polarization of the 27.6 GeV electrons/positrons of HERA. Part of this effort also included convincing people to install a gas storage cell internal to the HERA lepton ring as part of a polarized gas target system. When this experiment, HERMES, finally turned on in 1995, it marked the beginning of an extremely successful physics program that ran until 2007, the shutdown of the HERA facility. During those years, HERMES took a wealth of data with longitudinally polarized H, D, and 3He targets, with transversely polarized H, as well as a wide range of unpolarized nuclei. In fact, analysis and publication of these data are still ongoing, as for the other HERA experiments. This talk will focus on some of the highlights of the HERMES program, with emphasis of exploiting the polarized beam, but also remembering some of the pioneering measurements, e.g., the first observation of the Sivers and Collins effects in semi-inclusive deep-inelastic scattering. Besides the discussion of the physics results, the talk will also reflect on the early years, e.g., on how the experiment and the collaboration was formed, to celebrate this milestone in nucleon-spin physics.

description: Results from the study of exclusive $\rho^0$-meson electroproduction by the HERMES experiment, using the 27.6 GeV longitudinally polarized electron/positron beam of HERA and a transversely polarized hydrogen target, are presented. In analysis of the angular dependence of the distribution of the decay pions, 25 parameters are extracted, which determine the real and imaginary parts of the ratios of several helicity amplitudes describing $\rho^0$-meson production by a virtual photon. The transverse target polarization allows for the first time the extraction of ratios of a number of nucleon-helicity-flip amplitudes. Results obtained in a handbag approach based on generalized parton distributions taking into account the contribution from pion exchange are found to be in good agreement with these ratios. Within the model, the data favor a positive sign for the $\pi - \rho^0$ transition form factor. By also exploiting the longitudinal beam polarization, a total of 71 $\rho^0$ spin-density matrix elements is determined from the extracted 25 parameters, in contrast to only 53 elements as directly determined in earlier analyses.This presentation is complemented by a discussion of earlier HERMES results on exclusive electroproduction of $\rho^0$ and $\omega$-mesons.
Medium-induced modification of kaons spectra measured in SIDIS at HERMES

description: The predicted high sensitivity of the nuclear modification factor for $K^-$ in SIDIS in respect to the medium-induced flavour conversion is studied at HERMES experiment. Unlike $\pi^+$, $\pi^-$ and $K^+$ nuclear modification factor for $K^-$ is assumed to increase at high value of Bjorken variable x and a hadron fraction energy z. The experimental signature of this phenomenon is an enhanced $K^-$ yields compared with those of $K^+$ for high Bjorken-x and z range. This is consequence of parton energy loss of the leading quarks. The Bjorken-x spectra of nuclear attenuation ratios for charged pions and kaons will be presented in different slices of z extracted on Ne, Kr and Xe targets.

description: The issue of the quantitative analysis of time-resolved photoluminescence experiments is addressed by developing and describing two approaches for determination of unimolecular lifetime, bimolecular recombination coefficient, and equilibrium free-carrier concentration, based on a quite general second-order expression of the electron-hole recombination rate. Application to the case of band-edge emission of ZnO single crystals is reported, evidencing the signature of sub-nanosecond second-order recombination dynamics for optical transitions close to the interband excitation edge. The resulting findings are in good agreement with the model prediction and further confirm the presence, formerly evidenced in literature by non-optical methods, of near-surface conductive layers in ZnO crystals with sheet charge densities of about 3÷5*10^13 cm^-2

description: High school is a critical period for science identity development. Teacher influences are important but under-researched. Teachers’ growth-mindset practices may help students meet the growing challenges to their ability, achievement, and identity in science and have long-term influences, especially for underrepresented students. We explored U.S. high school students’ perceptions of science teachers’ growth-mindset practices at ninth grade and the effect on the mean development trajectory of their science identity over six years. Three waves of data from a nationally representative sample of 15,648 students were analysed through longitudinal multilevel models. Data from underrepresented ethnic minorities (n = 4,485), students with low socioeconomic status (low-SES) (n = 2,219), and female students (n = 7,823) were analysed separately from the overall sample. Perceived teachers’ growth-mindset practices significantly predicted initial science identity at ninth grade for the overall sample, ethnic minorities, and female students, as well as science identity development over time for all four samples, before controlling student competence beliefs, gender, race, and SES. The long-term effect was more salient for the ethnic minority and low-SES students. We extended prior work by examining the effect of perceived teachers’ mindset practices in the science discipline, particularly the long-term effect, while most research on STEM motivation and identity from a growth mindset perspective focused on student mindset, the math discipline, and the short-term effect of mindset. Results suggest continued teacher training on growth mindset for helping students develop science identity, especially for ethnic minority and low-SES students.
