Lessons from the 3d U(1) Gross-Neveu Model

The effectiveness of the Glasgow algorithm is explored via implementation in the 3d U(1) Gross-Neveu model and the realisation of the Goldstone mechanism in this model is compared and contrasted with its realisation in QCD.Comment: 6 pages, 5 eps figs, To appear in Proceedings of "QCD at Finite Baryon Density" workshop, Bielefeld, 27-30 April 199

Creatress: A Woman\u27s Hand

Using stylized and abstracted sculptural interpretations of She—Great Mother, Mother Nature, Earth Goddess, Creatress, Gaia, female sexuality, and the feminine aspects of nature; a wide range of differing chemicals and temperatures for the development of various clay bodies; and a vivid color palette to reflect ideas, feelings, and moods, I present a story of woman as metaphor for Earth and nature, an immense organic, ecological, and conscious whole. Incorporating found objects (natural and manmade) and fibers (organic and synthetic) with my clay imagery, I offer an awareness of the roles ofwomen from around the world in the spiritual and psychological development of cultures and the impact of those roles on our global society. From a scientific and ecological perspective as well as from an inner, spiritual perspective, I present an often neglected story that spans 30,000 years

Access to breast prostheses via a government-funded service in Victoria, Australia

For many women, the only alternative to breast reconstruction following a mastectomy is to use external prostheses, which need replacing regularly at a cost of up to $395 per prosthesis. Commonwealth and state governments across Australia have responded to this need by providing subsidies to assist in the purchase of breast prostheses. However, current arrangements have been highly variable and sometimes difficult to access. As part of a larger review of breast pros-thesis services in Victoria, Australia, the aim of this research was to evaluate client satisfaction among Victorian women who accessed funds through the State Government\u27s Aids and Equipment Program, compare the responses of the program service providers with the experiences of clients accessing funding, and identify opportunities to improve service provision. <br /

Chiral Symmetry Restoration and Realisation of the Goldstone Mechanism in the U(1) Gross-Neveu Model at Non-Zero Chemical Potential

We simulate the Gross-Neveu model in 2+1 dimensions at nonzero baryon density (chemical potential mu =/= 0). It is possible to formulate this model with a real action and therefore to perform standard hybrid Monte Carlo simulations with mu =/= 0 in the functional measure. We compare the physical observables from these simulations with simulations using the Glasgow method where the value of mu in the functional measure is fixed at a value mu_upd. We find that the observables are sensitive to the choice of mu_upd. We consider the implications of our findings for Glasgow method QCD simulations at mu =/= 0. We demonstrate that the realisation of the Goldstone mechanism in the Gross-Neveu model is fundamentally different from that in QCD. We find that this difference explains why there is an unphysical transition in QCD simulations at mu =/= 0 associated with the pion mass scale whereas the transition in the Gross-Neveu model occurs at a larger mass scale and is therefore consistent with theoretical predictions. We note classes of theories which are exceptions to the Vafa-Witten theorem which permit the possibility of formation of baryon number violating diquark condensates.Comment: 28 pages RevTe

The Human Microbiome and Recurrent Abdominal Pain in Children

This project explores the nature of the human intestinal microbiome in healthy children and children with recurrent abdominal pain. The overall goal is to obtain a robust knowledge base of the intestinal microbiome in children without evidence of pain or gastrointestinal disease and in those with recurrent abdominal pain (functional abdominal pain (FAP) and FAP associated with changes in bowel habits, i.e., irritable bowel syndrome or IBS). Specific aims include: 1. Characterize the composition of the gut microbiome in healthy children by DNA sequencing. 2. Determine the presence of disease-specific organism signatures of variable gut microbiomes in children with recurrent abdominal pain. 3. Perform functional gut metagenomics by evaluation of whole community gene expression profiles and discovery of disease-specific pathway signatures. Multiple strategies have been deployed to navigate and understand the nature of the intestinal microbiome in childhood. These strategies included 454 pyrosequencing-based strategies to sequence 16S rRNA genes and understand the detailed composition of microbes in healthy and disease groups. Microarray-based hybridization with the PhyloChip and quantitative real-time PCR (qPCR) probes were applied as complementary strategies to gain an understanding of the intestinal microbiome from various perspectives. Data collected and analyzed during the HMP UH2 Demo project, from a set of healthy and IBS children (7-12 yo) may enable the identification of core microbiomes in children, in addition to variable components that may distinguish healthy from diseased pediatric states. Twenty-two children with IBS and twenty-two healthy children were enrolled and analyzed in the UH2 phase of this study. The planned enrollment targets for the UH2/3 phases include 50 healthy children, 50 children with FAP and 50 children with IBS (minimum of 3 time points per child). We are currently analyzing the dataset for the presence of disease-specific signatures in the human microbiome, and correlating these microbial signatures with pediatric health or IBS disease status in addition to IBS subtype (e.g., diarrhea-vs constipation-predominant). In the next phase, whole genome shotgun sequencing and metatranscriptomics will be performed with a subset of children in each group. This study explores the nature of core and variable human microbiome in pre-adolescent healthy children and children with IBS. &#xd;&#xa

Do echinoderm genomes measure up?

Echinoderm genome sequences are a corpus of useful information about a clade of animals that serve as research models in fields ranging from marine ecology to cell and developmental biology. Genomic information from echinoids has contributed to insights into the gene interactions that drive the developmental process at the molecular level. Such insights often rely heavily on genomic information and the kinds of questions that can be asked thus depend on the quality of the sequence information. Here we describe the history of echinoderm genomic sequence assembly and present details about the quality of the data obtained. All of the sequence information discussed here is posted on the echinoderm information web system, Echinobase.org

Intergenerational learning and place-making in a deindustrialized locality: “Tracks of the Past” in Lanarkshire, Scotland

Previously deposited in Glasgow University repository on 20 May 2022 at: https://eprints.gla.ac.uk/271365/This paper contributes to scholarship on the long experience of deindustrialization. It emphasizes contemporary place-making in navigating the much-changed socioeconomic landscapes that the closure of mills, mines, shipyards and factories have left behind. The ‘half-life of deindustrialization' suggests these experiences have been received through understandings of labour and community with origins in the industrial era. ‘Tracks of the Past' was a school-based education project themed around workers' occupation of Caterpillar's earth-moving machinery plant in Lanarkshire, Scotland. The occupation was a response to Caterpillar's shock closure announcement and the loss of 1,200 jobs. It lasted 103 days between January and April 1987 when closure was reluctantly conceded. A Caterpillar Workers Legacy Group (CWLG) commemorated the occupation's thirtieth anniversary. During 2018, academics collaborated with the CWLG to develop a curriculum for a local high school class. ‘Tracks' produced lessons where students engaged with archival sources and physical objects, interviewed members of the CWLG and conducted online research. The ‘learning journey' montages that the students produced combined conversations in 2018 with sources from three decades earlier, often reflecting on the occupation as a historical episode in a highly localised context. Others implicated the closure within an international pattern, linking Caterpillar’s divestment to the actions of multinationals in the contemporary global economy. In neither case did the invocation of the occupation lead to a straightforward translation of the occupation into contemporary workplace justice issues as the CWLG had hoped. However, these results did suggest a creative deployment of the past that rationalised the occupation with reference to contemporary deindustrialized contexts. These findings demonstrate the utility of the half-life through a lingering industrial past, but also demonstrate the need to conceptualise agents or custodians of labour history and challenge the linearity of passing time that an incrementally receding industrial era implicates.https://doi.org/10.1017/S0147547922000011inpressinpres

Engaging Experts and Patients to Refine the Nutrition Literacy Assessment Instrument

Background An objective measure of nutrition literacy is unavailable for use in the primary care population. The Nutrition Literacy Assessment instrument (NLit) is a tool designed to measure nutrition literacy across six domains and has been previously piloted in breast cancer and parent populations. The purpose of this research was to engage nutrition experts and patients to guide revisions of the NLit for use in adult primary care. Methods Experts (n=5) reviewed each item in the NLit using a survey to assign rankings of their agreement according to relevance, clarity, and reading difficulty. Relevance rankings were used to calculate Scale Content Validity Index. After suggested revisions were made, patients (n=12) were recruited from urban primary care clinics of a University Medical Center located in the Midwestern United States and were interviewed by trained researchers using the cognitive interview approach to generate thoughts, feelings, and ideas regarding NLit items. Data analysis involved qualitative and quantitative methods. Results Content validity from expert review was confirmed with a total Scale Content Validity Index of 0.90. Themes emerging from the cognitive interviews resulted in changes in the NLit to improve instrument clarity. Conclusion These data suggest the NLit achieves its target constructs, is understood by the target audience, and is ready to undergo validity and reliability testing within the primary care population
