description: We study the fermion pair production from a strong electric field in boost-invariant coordinates in (3+1) dimensions and exploit the cylindrical symmetry of the problem. This problem has been used previously as a toy model for populating the central-rapidity region of a heavy-ion collision (when we can replace the electric by a chromoelectric field). We derive and solve the renormalized equations for the dynamics of the mean electric field and current of the produced particles, when the field is taken to be a function only of the fluid proper time $τ= \sqrt{t^2-z^2}$. We determine the proper-time evolution of the comoving energy density and pressure of the ensuing plasma and the time evolution of suitable interpolating number operators. We find that unlike in (1+1) dimensions, the energy density closely follows the longitudinal pressure. The transverse momentum distribution of fermion pairs at large momentum is quite different and larger than that expected from the constant field result.

Yet another surprise in the problem of classical diamagnetism

description: The well known Bohr-van Leeuwen Theorem states that the orbital diamagnetism of classical charged particles is identically zero in equilibrium. However, results based on real space-time approach using the classical Langevin equation predicts non-zero diamagnetism for classical unbounded (finite or infinite) systems. Here we show that the recently discovered Fluctuation Theorems, namely, the Jarzynski Equality or the Crooks Fluctuation Theorem surprisingly predict a free energy that depends on magnetic field as well as on the friction coefficient, in outright contradiction to the canonical equilibrium results. However, in the cases where the Langevin approach is consistent with the equilibrium results, the Fluctuation Theorems lead to results in conformity with equilibrium statistical mechanics. The latter is demonstrated analytically through a simple example that has been discussed recently.

description: We describe an astrometric and spectroscopic campaign to confirm the youth and association of a complete sample of candidate wide companions in Taurus and Upper Sco. Our survey found fifteen new binary systems (3 in Taurus and 12 in Upper Sco) with separations of 3-30" (500-5000 AU) among all of the known members with masses of 2.5-0.012 Msun. The total sample of 49 wide systems in these two regions conforms to only some expectations from field multiplicity surveys. Higher-mass stars have a higher frequency of wide binary companions, and there is a marked paucity of wide binary systems near the substellar regime. However, the separation distribution appears to be log-flat, rather than declining as in the field, and the mass ratio distribution is more biased toward similar-mass companions than the IMF or the field G dwarf distribution. The maximum separation also shows no evidence of a limit at <5000 AU until the abrupt cessation of any wide binary formation at system masses of ~0.3 Msun. We attribute this result to the post-natal dynamical sculpting that occurs for most field systems; our binary systems will escape to the field intact, but most field stars are formed in denser clusters and do not. In summary, only wide binary systems with total masses <0.3 Msun appear to be "unusually wide".

description: BackgroundDespite the accumulation of research papers on aspirin and cancer, there is doubt as to whether or not aspirin is an acceptable and effective adjunct treatment of cancer. The results of several randomised trials are awaited, and these should give clear evidence on three common cancers: colon, breast and prostate. The biological effects of aspirin appear likely however to be of relevance to cancer generally, and to metastatic spread, rather than just to one or a few cancers, and there is already a lot of evidence, mainly from observational studies, on the association between aspirin and survival in a wide range of cancers.AimsIn order to test the hypothesis that aspirin taking is associated with an increase in the survival of patients with cancer, we conducted a series of systematic literature searches to identify clinical studies of patients with cancer, some of whom took aspirin after having received a diagnosis of cancer.ResultsThree literature searches identified 118 published observational studies in patients with 18 different cancers. Eighty-one studies report on aspirin and cancer mortality and 63 studies report on all-cause mortality. Within a total of about a quarter of a million patients with cancer who reported taking aspirin, representing 20%-25% of the total cohort, we found aspirin to be associated with a reduction of about 20% in cancer deaths (pooled hazard ratio (HR): 0.79; 95% confidence intervals: 0.73, 0.84 in 70 reports and a pooled odds ratio (OR): 0.67; 0.45, 1.00 in 11 reports) with similar reductions in all-cause mortality (HR: 0.80; 0.74, 0.86 in 56 studies and OR: 0.57; 0.36, 0.89 in seven studies). The relative safety of aspirin taking was examined in the studies and the corresponding author of every paper was written to asking for additional information on bleeding. As expected, the frequency of bleeding increased in the patients taking aspirin, but fatal bleeding was rare and no author reported a significant excess in fatal bleeds associated with aspirin. No author mentioned cerebral bleeding in the patients they had followed.ConclusionsThere is a considerable body of evidence suggestive of about a 20% reduction in mortality in patients with cancer who take aspirin, and the benefit appears not to be restricted to one or a few cancers. Aspirin, therefore, appears to deserve serious consideration as an adjuvant treatment of cancer, and patients with cancer, and their carers, have a right to be informed of the available evidence.

description: Human organoid systems recapitulate key features of organs offering platforms for modelling developmental biology and disease. Tissue-derived organoids have been widely used to study the impact of extrinsic niche factors on stem cells. However, they are rarely used to study endogenous gene function due to the lack of efficient gene manipulation tools. Previously, we established a human foetal lung organoid system (Nikolić et al., 2017). Here, using this organoid system as an example, we have systematically developed and optimised a complete genetic toolbox for use in tissue-derived organoids. This includes ‘Organoid Easytag’, our efficient workflow for targeting all types of gene loci through CRISPR-mediated homologous recombination followed by flow cytometry for enriching correctly targeted cells. Our toolbox also incorporates conditional gene knockdown or overexpression using tightly inducible CRISPR interference and CRISPR activation which is the first efficient application of these techniques to tissue-derived organoids. These tools will facilitate gene perturbation studies in tissue-derived organoids facilitating human disease modelling and providing a functional counterpart to many ongoing descriptive studies, such as the Human Cell Atlas Project.

description: Phosphorus is a crucial element in agriculture to feed the fast-growing global population. Its sustainable supply has ecological, social and human dimensions and it is classified as critical to European industries. On the other side, phosphate can also be critical for the producing countries as phosphate mining contributes to their national economies. This work investigates implications of environmental and social impacts and the resource governance to mitigate global phosphate criticality.

description: Noncommunicable diseases contribute the greatest to global mortality. Unhealthy diet—a prominent risk factor—is intricately linked to urban built and food environments and requires intersectoral efforts to address. Framings of the noncommunicable disease problem and proposed solutions within global and African regional diet-related policy documents can reveal how amenable the policy landscape is for supporting intersectoral action for health in low-income to middle-income countries. This study applied a document analysis approach to undertake policy analysis on global and African regional policies related to noncommunicable disease and diet. A total of 62 global and 29 African regional policy documents were analysed. Three problem frames relating to noncommunicable disease and diet were identified at the global and regional level, namely evidence-based, development, and socioeconomic frames. Health promotion, intersectoral and multisectoral action, and evidence-based monitoring and assessment underpinned proposed interventions to improve education and awareness, support structural changes, and improve disease surveillance and monitoring. African policies insufficiently considered associations between food security and noncommunicable disease. In order to effectively address the noncommunicable disease burden, a paradigm shift from ‘health for development’ to ‘development for health’ is required across non-health sectors. Noncommunicable disease considerations should be included within African food security agendas, using malnutrition as a possible intermediary concept to motivate intersectoral action to improve access to nutritious food in African low-income to middle-income countries.

description: Access to quality internet has become increasingly important since the spread of the novel coronavirus (COVID-19). During 2020 and 2021, people have needed to transition various services such as education and meetings to online platforms to comply with social distancing measures aimed at reducing the spread of the virus. However, not all people have access to affordable, fast and reliable internet, making their ability to access these alternatives limited. This In Brief analyses a survey of device ownership levels and internet access strategies of undergraduate students enrolled at the University of Papua New Guinea (UPNG) in Port Moresby. The findings can inform policymakers and educators who are considering the possibilities and challenges of digital education and internet accessibility in the Pacific.

description: Huntington’s disease is a dominantly inherited neurodegenerative disorder caused by the expansion of a CAG repeat, encoding for the amino acid glutamine (Q), present in the first exon of the protein huntingtin. Over the threshold of Q39 HTT exon 1 (HTTEx1) tends to misfold and aggregate into large intracellular structures, but whether these end-stage aggregates or their on-pathway intermediates are responsible for cytotoxicity is still debated. HTTEx1 can be separated into three domains: an N-terminal 17 amino acid region, the polyglutamine (polyQ) expansion and a C-terminal proline rich domain (PRD). Alongside the expanded polyQ, these flanking domains influence the aggregation propensity of HTTEx1: with the N17 initiating and promoting aggregation, and the PRD modulating it. In this study we focus on the first 11 amino acids of the PRD, a stretch of pure prolines, which are an evolutionary recent addition to the expanding polyQ region. We hypothesize that this proline region is expanding alongside the polyQ to counteract its ability to misfold and cause toxicity, and that expanding this proline region would be overall beneficial. We generated HTTEx1 mutants lacking both flanking domains singularly, missing the first 11 prolines of the PRD, or with this stretch of prolines expanded. We then followed their aggregation landscape in vitro with a battery of biochemical assays, and in vivo in novel models of C. elegans expressing the HTTEx1 mutants pan-neuronally. Employing fluorescence lifetime imaging we could observe the aggregation propensity of all HTTEx1 mutants during aging and correlate this with toxicity via various phenotypic assays. We found that the presence of an expanded proline stretch is beneficial in maintaining HTTEx1 soluble over time, regardless of polyQ length. However, the expanded prolines were only advantageous in promoting the survival and fitness of an organism carrying a pathogenic stretch of Q48 but were extremely deleterious to the nematode expressing a physiological stretch of Q23. Our results reveal the unique importance of the prolines which have and still are evolving alongside expanding glutamines to promote the function of HTTEx1 and avoid pathology.

Applied epidemiology in communicable diseases, immunisation, and environmental health in Tasmania

Publisher: name: The Australian National University

description: This thesis describes four major projects and other course requirements completed for the degree of Master of Philosophy in Applied Epidemiology (MAE) during field placements in 2021 and 2022. In 2021 I was placed in the Communicable Diseases Prevention Unit (CDPU) in the Tasmanian Department of Health, and completed three major projects. I was closely involved in the development, design, and implementation of a local passive surveillance system for adverse events following immunisation (AEFI), launched in the context of the beginning of the SARS-CoV-2 (COVID-19) mass vaccination campaign in Tasmania in March 2021. I then evaluated the performance of this AEFI surveillance system in November 2021, and made recommendations to improve the surveillance system for its continued use beyond the COVID-19 pandemic. I analysed gonococcal infection notification data received by the CDPU between 2010 and 2021, as in-depth analysis and reporting had not been performed for some time as regular business had been interrupted by the COVID-19 pandemic. I made some recommendations for improved gonococcal infection surveillance in Tasmania, and for consideration of future targeted public health messaging. Finally, I led an outbreak investigation for a cluster of cases of foodborne gastroenteritis at a catered workshop in a hotel venue in the north-east of Tasmania. I performed a cohort study, and while a pathogen and vehicle were not determined with certainty, a number of important public health actions occurred as a result of the investigation. In 2022 I was placed in the Environmental Health team at the Menzies Institute for Medical Research, University of Tasmania. The focus of this team is predominantly on air quality, and this experience provided an interesting insight into environmental epidemiology. I completed my epidemiological study during this placement. This was an evaluation of the association between key air pollutants, particulate matter less than 2.5 micrometres in diameter (PM2.5) and nitrogen dioxide (NO2), and educational outcomes in school-aged children in Australia. I used school-level National Assessment Program - Literacy and Numeracy (NAPLAN) scores as the outcome, and performed multivariable linear regressions to evaluate associations. We found that PM2.5 was associated with poorer scores, which supports emerging evidence that air quality negatively impacts on educational outcomes. Educational attainment is an important social determinant of health, and we have planned further studies to be conducted as a result of these findings. Teaching, epidemiological, and other public health activities undertaken during my field placements are described in the final chapter.

description: Following its launch in June 2008, the Fermi Gamma-ray Space Telescope (Fermi) began a sky survey in August. The Large Area Telescope (LAT) on Fermi in 3 months produced a deeper and better-resolved map of the gamma-ray sky than any previous space mission. We present here initial results for energies above 100 MeV for the 205 most significant (statistical significance greater than ~10-sigma) gamma-ray sources in these data. These are the best-characterized and best-localized point-like (i.e., spatially unresolved) gamma-ray sources in the early-mission data.

Gender, Reception and 'The Drover's Wife' Phenomenon
Creators: name: Li, Xiang
Publisher: name: The Australian National University
Year: 2023

description: This thesis investigates the literary and cultural phenomenon of 'The Drover's Wife'. Since Henry Lawson published the short story 'The Drover's Wife' in 1892, it has inspired many reworkings. Australian artists have moulded the iconic story into various shapes and given the archetypal bushwoman one identity after another. From the 1890s to the 2020s, the thesis examines more than 25 versions and variations across different genres and forms, including Louisa Lawson's essay 'The Australian Bush-Woman' (1889), Russell Drysdale's painting The Drover's Wife (1945), Murray Bail's short story 'The Drover's Wife' (1975), Anne Gambling's story 'The Drover's De Facto' (1986), Chris Eipper's story 'The Wife's Drover' (1996), Luke O'Shea's 2011 country song, Frank Moorhouse's 2017 anthology The Drover's Wife: A Collection, Ryan O'Neill's book The Drover's Wives: 99 Reinterpretations of Henry Lawson's Australian Classic (2018) as well as Leah Purcell's 'Moll Johnson' adaptations from 2016 to 2021, a play, a novel and a film. By drawing from reception, rewriting, adaptation and genre studies, this thesis considers 'The Drover's Wife' as a phenomenon of rewriting. It focuses on the intricate intertextual relations between each version and contemplates the acts of reception and reproduction. More importantly, the thesis concerns the gendered nature of Australian cultural discourse and the relationship between gender, race and the so-called 'national identity'. Through 'The Drover's Wife', writers, readers and critics negotiate their understanding of gender roles, relations and identities. Rewriting becomes a means to rethink existing conceptions of gender. And 'The Drover's Wife' phenomenon enables the exploration of the changing conceptualisation of gender roles and relations in Australian culture.
Studies on the nitrogen metabolism of Verticillium Albo-Atrum Reinke & Berth.
Creators: name: Woodbury, William
Publisher: name: University of British Columbia
Year: 2011

description: Studies on the ability of Verticillium albo-atrum Reinke & Berth, to grow on a synthetic basal medium incorporating various organic and inorganic sources of nitrogen indicate that nitrate serves as the best single source of nitrogen. V. albo-atrum is able to utilize the known inorganic intermediates of nitrate reduction with the exception of hydroxylamine which was toxic at the concentration used. Enzymatic studies, using homogenates of mycelium grown on the synthetic medium with nitrate or peptone as the source of nitrogen, indicate the adaptive nature of the enzymes responsible for nitrate reduction since only the nitrate-grown mycelium was found to reduce nitrate. On the basis of evidence presented, it is concluded that the adaptive nature of nitrate reductase and the preferential utilization of nitrate by V. albo-atrum may be factors in the effects of nitrogen nutrition of the host on the incidence and severity of Verticillium wilt.

title: Artificial Immune Systems for Web Content Mining: Focusing on the Discovery of Interesting Information
Creators: name: Secker, Andrew D.
Publisher: name: University of Kent
Year: 2023

description: This thesis explores the way in which biological metaphors can be applied to web content mining and, more specifically, the identification of interesting information in web documents. Web content mining is the use of content found on the web, most usually the text found on web pages, for data mining tasks such as classification. Due to the nature of the search domain, i.e. the web content is noisy and undergoing constant change, an adaptive system is required. The discovery of interesting information is an advance on basic text mining in that it aims to identify text that is novel, unexpected or surprising to a user, whilst still being relevant. This thesis investigates the use of Artificial Immune Systems (AIS) applied to discovery of interesting information as AIS are thought to confer the adaptability and learning required for this task. Two novel Artificial Immune Systems are described and tested. AISEC (Artificial Immune System for Interesting E-mail Classification) is a novel, immune inspired system for the classification of e-mail. It is shown that AISEC performs with a predictive accuracy comparable to a naïve Bayesian algorithm when continually classifying e-mail collected from a real user. This section contributes to the understanding of how AIS react in a continuous learning scenario. Following from the knowledge gained by testing AISEC, AISIID (Artificial Immune system for Interesting Information Discovery) is then described. A study involving the subjective evaluation of the results by users is undertaken and AISIID is seen to discover pages rated more interesting by users than a comparative system. The results of this study also reveal AISIID performs with subjective quality similar to the well known search engine, Google. This leads to a contribution regarding a better understanding of the user's perception of interestingness and possible inadequacies in the current understanding of interestingness regarding text documents.

description: Internal diffusion-limited aggregation is a growth model based on random walk in Z^d. We study how the shape of the aggregate depends on the law of the underlying walk, focusing on a family of walks in Z^2 for which the limiting shape is a diamond. Certain of these walks -- those with a directional bias toward the origin -- have at most logarithmic fluctuations around the limiting shape. This contrasts with the simple random walk, where the limiting shape is a disk and the best known bound on the fluctuations, due to Lawler, is a power law. Our walks enjoy a uniform layering property which simplifies many of the proofs.

description: We study the asymptotic properties of eigenfunctions of the Laplacian in the case of a compact Riemannian surface of nonpositive sectional curvature. We show that the Kolmogorov-Sinai entropy of a semiclassical measure for the geodesic flow is bounded from below by half of the Ruelle upper bound. We follow the same main strategy as in the Anosov case (arXiv:0809.0230). We focus on the main differences and refer the reader to (arXiv:0809.0230) for the details of analogous lemmas.

Se i cicli climatici sono direttamente correlati all’orbita descritta dalla Terra attorno al Sole, cosa succede se, ogni 405mila anni, l’influenza gravitazionale di Giove e Venere allunga seppur di poco l’orbita terrestre? Ne parla uno studio uscito su Pnas

title: Incorporation of LEO GNSS observations into global network solutions

description: This research focuses on specific aspects of geodesy with the aim of deepening the understanding of Earth's dynamic geodetic parameters and refining the precision and completeness of global network solutions. The work comprises various investigations, each addressing key aspects of geodetic research and contributing to a broader understanding. The central approach involves the integration of observations from Global Navigation Satellite Systems (GNSS) collected by satellite-based receivers aboard Low Earth Orbiters (LEOs) into the determination of a global GNSS network solution. The focus is on the influence of integrating LEO-GNSS observations on resulting parameters such as GNSS and LEO orbits, geodetic parameters, such as Earth's center-of-mass coordinates and Earth rotation parameters, and ground station coordinates.
Fundamental to this is the current state of realizing terrestrial reference frames (TRFs). The incorporation of LEO-GNSS observations addresses conceptual deficiencies in TRFs by considering the gravity field. Satellites in low Earth orbits play a crucial role, acting in the role of "Space Ties", and being highly sensitive to the gravitational field. These satellites become integral components for various satellite geodetic techniques, promising a comprehensive and improved representation of Earth's geodetic reference frame.
One aspect of the work involves an examination of traditional methods for precise orbit determination (POD) of LEOs using observations from the Global Positioning System (GPS). Traditionally relying on fixed GPS orbits and clock corrections derived from ground-based receivers, this work highlights the potential of integrating LEO-GNSS observations into global network solutions.
A comprehensive analysis, including data from LEOs, equipped with dual-frequency GNSS receivers, is methodically scrutinized through a joint least-squares adjustment process, resulting in a combined GNSS-LEO solution. The analysis shows a significant improvement in the observability of the estimated geodetic parameters.
Acknowledging the observational advantages of LEO satellites due to their proximity to the Earth's surface, this work emphasizes their complementary role alongside established systems like GPS. The investigation carefully analyzes the potential for further qualitative enhancements in the framework of network solutions when LEOs are seamlessly integrated, particularly in conjunction with multiple GNSS systems.

Spectral synthesis including massive binaries

description: We have constructed a new code to produce synthetic spectra of stellar populations that includes massive binaries. We have tested this code against the broadband colours of unresolved young massive stellar clusters in nearby galaxies, the equivalent widths of the Red and Blue Wolf-Rayet bumps in star-forming SDSS galaxies and the UV and optical spectra of the star forming regions Tol-A and B in NGC5398. In each case we find a good agreement between our models and observations. We find that in general binary populations are bluer and have fewer red supergiants, and thus significantly less flux in the I-band and at longer wavelengths, than single star populations. Also we find that Wolf-Rayet stars occur over a wider range of ages up to 10^7 years in a stellar population including binaries, increasing the UV flux and Wolf-Rayet spectral features at later times. In addition we find that nebula emission contributes significantly to these observed properties and must be considered when comparing stellar models with observations of unresolved stellar populations. We conclude that incorporation of massive stellar binaries can improve the agreement between observations and synthetic spectral synthesis codes, particularly for systems with young stellar populations.
