description: Giant enhancement of the nonlinear response of a single crystal Nb sample, placed in {\it a pumping ac magnetic field}, has been observed experimentally. The experimentally observed amplitude of the output signal is about three orders of magnitude higher than that seen without parametric pumping. The theoretical analysis based on the extended double well potential model provides a qualitative explanation of the experimental results as well as new predictions of two bifurcations for specific values of the pumping signal.

description: We show that the Dirac equation in 3+1 dimensions gives rise to supersymmetric patterns when the scalar and vector potentials are (i) Coulombic with arbitrary strengths or (ii) when their sum or difference is a constant, leading to relativistic pseudospin and spin symmetries. The conserved quantities and the common intertwining relation responsible for such patterns are discussed.

description: Existing theoretical works differ on whether three-dimensional Dirac and Weyl semimetals are stable to a short-range-correlated random potential. Numerical evidence suggests the semimetal to be unstable, while some field-theoretic instanton calculations have found it to be stable. The differences go beyond method: the continuum field-theoretic works use a single, perfectly linear Weyl cone, while numerical works use tight-binding lattice models which inherently have band curvature and multiple Weyl cones. In this work, we bridge this gap by performing exact numerics on the same model used in analytic treatments, and we find that all phenomena associated with rare regions near the Weyl node energy found in lattice models persist in the continuum theory: The density of states is non-zero and exhibits an avoided transition. In addition to characterizing this transition, we find rare states and show that they have the expected behavior. The simulations utilize sparse matrix techniques with formally dense matrices; doing so allows us to reach Hilbert space sizes upwards of $10^7$ states, substantially larger than anything achieved before.

description: A search for heavy neutral Higgs bosons is performed using the LHC Run 2 data, corresponding to an integrated luminosity of 139 fb$^{-1}$ of proton-proton collisions at $\sqrt{s}=13$ TeV recorded with the ATLAS detector. The search for heavy resonances is performed over the mass range 0.2-2.5 TeV for the $τ^+τ^-$ decay with at least one $τ$-lepton decaying into final states with hadrons. The data are in good agreement with the background prediction of the Standard Model. In the $M_{h}^{125}$ scenario of the Minimal Supersymmetric Standard Model, values of $\tanβ>8$ and $\tanβ>21$ are excluded at the 95% confidence level for neutral Higgs boson masses of 1.0 TeV and 1.5 TeV, respectively, where $\tanβ$ is the ratio of the vacuum expectation values of the two Higgs doublets.

The perspectical cloud: A critical reconsideration of Paolo Uccello's St. George and the dragon

description: In this paper, I will examine how Renaissance painter Paolo Uccello's two versions of St. George and the Dragon demonstrate a radical conception of spatial perspective, one that drastically differed from traditional models of linear perspective advanced by Fillippo Brunelleschi and Leon Battista Alberti. I argue that Uccello's sophisticated weaving of character drama and spatial reality in the second work promotes a new type of humanist painting by allowing an innovative viewer participation without promoting viewer preeminence. It therefore represents a perspectival manifesto for the artist which engages with the narrative as a way of situating the painting in both space and time. Although a legitimate alternative to linear perspective, the latter's historical and cultural significance has obscured our understanding of perspectivally nontraditional works made during the Renaissance.

description: The long-time dynamics of the 1D contact process suddenly brought out of an uncorrelated initial state is studied through a light-cone transfer-matrix renormalisation group approach. At criticality, the system undergoes ageing which is characterised through the dynamical scaling of the two-times autocorrelation and autoresponse functions. The observed non-equality of the ageing exponents a and b excludes the possibility of a finite fluctuation-dissipation ratio in the ageing regime. The scaling form of the critical autoresponse function is in agreement with the prediction of local scale-invariance.

Scaling Relations for Turbulence in the Multiphase Interstellar Medium

Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We employ a generalization of the She & Leveque model to study velocity scaling relations based on our simulations of thermal instability--induced turbulence. Being a by-product of the interstellar phase transition, such multiphase turbulence tends to be more intermittent than compressible isothermal turbulence. Due to radiative cooling, which promotes nonlinear instabilities in supersonic flows, the Hausdorff dimension of the most singular dissipative structures, D, can be as high as 2.3, while in supersonic isothermal turbulence D is limited by shock dissipation to D < 2. We also show that single-phase velocity statistics carry only incomplete information on the turbulent cascade in a multiphase medium. We briefly discuss the possible implications of these results on the hierarchical structure of molecular clouds and on star formation.

description: We investigate the appearance of closed timelike curves in quotients of plane waves along spacelike isometries. First we formulate a necessary and sufficient condition for a quotient of a general spacetime to preserve stable causality. We explicitly show that the plane waves are stably causal; in passing, we observe that some pp-waves are not even distinguishing. We then consider the classification of all quotients of the maximally supersymmetric ten-dimensional plane wave under a spacelike isometry, and show that the quotient will lead to closed timelike curves iff the isometry involves a translation along the u direction. The appearance of these closed timelike curves is thus connected to the special properties of the light cones in plane wave spacetimes. We show that all other quotients preserve stable causality.

description: During the 2000s a common view in government circles in Australia was that governments were over-investing in primary industry research and innovation. In agreement with this view, the Western Australian government lessened its support for primary industry research and innovation over the last decade. However, so great has been the erosion of funding and capability in research that the pressing problem is now perceived to be government’s underinvestment in primary industry research and innovation. Nonetheless, the government’s adverse current fiscal environment still constrains departmental budgets, so the case for government expenditure on primary industry research and innovation needs to be made and soundly argued. This report outlines the case for government expenditure on primary industry research and innovation.

description: In the recent development discourse, much emphasis has been placed on making agriculture more nutrition-sensitive as an important component in combating hunger and malnutrition among rural households in developing countries. In order to achieve this at scale, nutrition information could be diffused to farm households organized in community-based organizations (CBOs) through the existing agricultural extension systems. However, to date little is known about how information flows within CBOs and how extension interventions could be designed to deliver combined information on agriculture and nutrition. This study uses unique network data from 815 farm households in Kenya to investigate the structure and characteristics of agricultural and nutrition information networks within CBOs. Dyadic regressions are used to analyze the factors influencing link formation for the exchange of agricultural and nutrition information. In addition, we apply fixed-effects models to identify the characteristics of central persons driving information exchange in the two networks, as well as potentially isolated persons, who are excluded from information networks within their CBOs. Our results show that nutrition information is exchanged within CBOs, although to a limited extent, and mostly flows through the existing agricultural information links. Thus, diffusing nutrition information through agricultural extension systems may indeed be a viable approach. Our findings further suggest that group leaders and persons living in central locations are important drivers in the diffusion of information in both networks and may thus serve as suitable entry points for nutrition-sensitive extension programs. However, we also identify important heterogeneities in network characteristics. In particular, nutrition information is less often exchanged between men and women, and some group members are completely isolated from nutrition information exchange within their CBOs. We derive recommendations on taking these differences in network structure and characteristics into account when designing nutrition-sensitive extension programs.
title: CH₄ and N₂O from waste composting

Publisher: name: The Open University
Year: 2007

description: This research programme aimed to investigate methane (CH4) and nitrous oxide (N20) emissions from large-scale composting facilities, with particular emphasis on advanced and newly emerging composting technologies. The atmospheric concentrations of CH4 and N20 are increasing, and they are respectively the second and third largest contributors to the global greenhouse effect after carbon dioxide. During field trials at large-scale composting facilities and in laboratory studies, the generation of CH4 and N20 was detected from a range of composting processes. Gaseous emissions from composting result from the interaction of a complex combination of controlling factors influencing the microbial production of CH4 and N20. Waste biodegradability in particular was shown to have significant influence on emission of CH4 and N20. Compliance with the EU landfill directive will result in the composting of wastes of varying biodegradability, the effect of this compliance on emission of CH4 and N20 from composting requires further investigation. Emissions of CH4 and N20 during composting have not been adequately quantified in the UK. A future projection of the contribution of composting to the UK greenhouse gas inventory was an estimated 24.6 Kt CH4 year-1 and 2.5 Kt N20 year-1 from open windrows, which currently account for 80% of the composting systems employed. There is urgent need for further study into the emission of CH4 and N20 from the UK composting sector as the Kyoto protocol requires emissions from all sources to be accounted for. While significant emission of CH4 and N20 was recorded for open air mechanically turned windrow systems, the level of emissions from in-vessel composting facilities was more difficult to determine. The combination of in-vessel composting and open air windrow composting would appear to greatly mitigate emissions compared to windrow systems alone, but more research into the environmental benefits of combining composting systems is required.

description: We present an XMM observation of the distant galaxy cluster CL 0939+4713. The X-ray image shows pronounced substructure, with two main subclusters forming the cluster core. This is an indication that the cluster is a dynamically young system. This conclusion is supported by the temperature distribution: a hot region is found between the two main subclusters indicating that they are at the beginning of a major merger, and that they will collide in a few hundreds of Myr. The intra-cluster gas of CL 0939+4713 shows inhomogeneities in the metal distribution, with the optically richer subcluster having a higher metallicity.

description: We study the spectral properties of ergodic Schrödinger operators that are associated to a certain family of non-primitive substitutions on a binary alphabet. The corresponding subshifts provide examples of dynamical systems that go beyond minimality, unique ergodicity and linear complexity. In some parameter region, we are naturally in the setting of an infinite ergodic measure. The almost sure spectrum is singular and contains an interval. Some criteria for the exclusion of eigenvalues are fully characterized, including the existence of strongly palindromic sequences. Many of our structural insights rely on return word decompositions in the context of non-uniformly recurrent sequences. We introduce an associated induced system that is conjugate to an odometer.

description: Background: Excessive screen time may impede cognitive development in early childhood. Purpose: To examine the cross-sectional associations between screen time and expressive language, as well as working memory, in preschoolers. Methods: Participants were 97 preschoolers (36-60 months) in Alberta and Ontario, Canada in the supporting Healthy physical AcTive Childcare setting (HATCH) study. The time that children spent on watching television, videos or DVDs (television time) or playing video or computer games (video game time) on a television, computer, or potable device were assessed using a parental questionnaire. Total screen time and adherence to the screen time recommendation (≤1h/d) of the Canadian 24-Hour Movement Guidelines were calculated. Expressive vocabulary and working memory were assessed using the Early Years Toolbox. Due to the distribution, working memory was categorized as a binary variable based on the median score. The associations between screen time and cognitive development were examined using mixed models (expressive vocabulary) or generalized mixed models (working memory). Results: Pre-schoolers who had higher total screen time were less likely to have better working memory (OR=0.53;95%CI:0.31,0.89). Adherence to the screen time recommendation tended to be associated with better working memory (OR=3.35;95%CI:1.05,11.36), compared to non-adherence. Screen time was not associated with expressive vocabulary. Conclusion: Limiting total screen time to no more than one hour per day may facilitate executive function development in preschoolers. Screen time may be unrelated to expressive language development in this age group. Funding: The Canadian Institutes of Health Research (CIHR).

title: Predicting Function and Structure using Bioinformatics Protocols:Study of the Intracellular Regions of the Jagged and Delta Protein Families
Creators: name: Ivanova, Neli
Publisher: name: The Open University
Year: 2007

description: The type I membrane-spanning proteins Jagged (Jagged-i and -2) and Delta (Delta-l, - 3 and -4) are the human ligands of Notch receptors, which mediate key signaling events in cell differentiation and morphogenesis. The Jagged and Delta proteins are composed of a relatively large extracellular region and of a 100-150 residue, yet uncharacterized cytoplasmic tail, which has been recently found to be important in Notch bi-directional signaling. We applied bioinformatics methods to analyze the intracellular region of human Notch ligands, and to predict their structural and functional properties. We searched databases for orthologues, and found that while the intracellular region is evolutionaiy well conserved within the same ligand type, a wide variability is observed in different ligands. No significant similarity was found between the intracellular region of Jagged and Delta and proteins of known 3D structure. Globularity and disorder predictions indeed suggest that these regions are largely unstructured. However, secondary structure predictions show that these regions have some propensity to form local secondary structure elements. Functional predictions based on pattern recognition imply that the specificity in the Notch machinery response might be related to specific post-translational modifications and binding motifs in the ligand cytoplasmic tail, rather than to specific interactions between the receptors and the extracellular region of the ligands. We also speculate that, given the unusual amino acid composition, the cytoplasmic tail of Jagged and Delta might be involved in zinc binding.
title: An analysis of gender practice of Tamil Christian women with particular reference to women of Kodambakkam Church of South India Risen Redeemer's Church in Chennai.
Creators: name: Herbert, Beulah
Publisher: name: The Open University
Year: 2006

description: This study looks at the gender practice of Tamil Christian women in Chennai. The self perceptions and self-constructions of the women of the sample from the Church of South India in Kodambakkam, Chennai, provide material to answer the research question, ‘Who is a Tamil Christian woman at the turn of the millennium?’ Focus groups and interview methods are used to collect the data. A feminist narrative methodology is adopted. For the narrative analysis, categories from relevant Indian family studies and those emerging from the fieldwork are used. This use of the narrative method enables the researcher to elicit the self- perceptions and self-constructions of the women, unlike some studies employing methods which produce perceptions and definitions about women by others and not perceptions by and of the women about themselves.

The analysis of the narratives reveals that the women neither perceive themselves nor construct their self-identities according to the usual rhetoric found in secular and theological gender studies. Religion plays an important role in shaping their self-perception and selfconstruction but according to their own understanding and interpretation, not as an oppressive doctrinal machine. Further the various narratives show that the perception and identity construction of these women are complex and multifarious. However it also emerges that the identity construction is a performance within the context of the narration adopted by the narrators to fit their common sense understanding of a ‘tellable story’ by the use of various strategies, tools and mechanisms of storytelling. Thus the answer to the question who a Tamil Christian woman is at the turn of the millennium is achieved through the collective, complex, multifaceted stories of the narrators emplotting their lived experiences of gender practice.

description: Background: Imprecise measurement of PA might distort estimates of the effects of regular PA on musculoskeletal health. Purpose: To explore the relationship between physical activity [PA] and chronic back disorders [CBD] in Canadian adults using either accelerometer-based or self-reported PA measures. Methods: Using cross-sectional data from Canadian adults [18-75 years] from the 2014/15 and 2016/17 Canadian Health Measures Survey [CHMS], we compared the relationship between CBD and meeting the Canadian PA guidelines of ‘150 min/week or more of moderate-to-vigorous PA’ using both accelerometer-based and self-reported PA measures. Two models were fitted: one containing self-reported PA, and another containing accelerometer-based PA, each model adjusted for several covariates. The beta coefficients obtained were evaluated using the Z test for equality of coefficient and a newly developed bias attributable to PA measurement [BAPAM] indicator. Results: The percentage of participants meeting the Canadian PA guidelines was 57.3% using the self-reported and 17.0% using the accelerometer-based PA measures, respectively. Meeting the Canadian PA guidelines was not associated with CBD, whether PA was measured by an accelerometer or by self-report. The Z test [ p=0.962], and the BAPAM indicator = 0.038 [95% CI -2.42, 2.49; p=0.443] showed that the coefficients of the association under study were not significantly different. Conclusions: A BAPAM indicator between 0 and 1 suggested a potential bias to the null hypothesis of no association; however, this bias was not statistically significant.

description: On March 25, 1957, assembled in Rome's festively decorated Capitol, the representatives of six European nations --to the accompaniment of the triumphant ringing of the Eternal City's bells--signed the treaty for the atomic integration of their countries under the supranational authority as a step toward a United States of Europe.The Atomic Community's basic objective is a contribution toward a higher standard of living in the Member States through pooling of their resources for the development of cheap atomic power to meet ever-increasing energy needs while at the same time providing greater independence of oil from the politically unstable areas of the Middle East.

description: Difficult it is to formulate achievable sensitivity bounds for quantum multiparameter estimation. Consider a special case, one parameter from many: many parameters of a process are unknown; estimate a specific linear combination of these parameters without having the ability to control any of the parameters. Superficially similar to single-parameter estimation, the problem retains genuinely multiparameter aspects. Geometric reasoning demonstrates the conditions, necessary and sufficient, for saturating the fundamental and attainable quantum-process bound in this context.

description: We study the long time behavior of an Ornstein-Uhlenbeck process under the influence of a periodic drift. We prove that, under the standard diffusive rescaling, the law of the particle position converges weakly to the law of a Brownian motion whose covariance can be expressed in terms of the solution of a Poisson equation. We also derive upper bounds on the convergence rate.

description: Using event-by-event fluctuations, we study the diffusion parameters of net-charge, net-pion, net-kaon, and net-proton in the heavy-ion jet interaction generator (HIJING), and ultra-relativistic quantum molecular dynamics (UrQMD) models at different collision energies \sqsn available at BNL Relativistic Heavy Ion Collider (RHIC). The diffusion parameter ($σ$) of net-charge and identified particles are estimated in rapidity space at various \sqsn. It is observed that, the $σ$ values are independent of collision energies but emphasises the particle-species dependence of diffusion coefficient in the QGP medium. The present work on particle-species dependence of diffusion coefficient provides a baseline for comparison with the experimental data.

title: Targeting cancer through tumor-selective mRNA stabilization
Creators: name: Ahmed, Atique U.
Publisher: name: The Open University

description: The success of cancer gene therapy is hindered by various physiological barriers to therapeutic vector transport from the site of injection to the nucleus of all the tumor cells. The application of replicating viruses for the treatment of cancers can overcome this problem. But this approach is limited by normal tissue tolerance of toxicity determined by local concentration of transgene products and viral proteins. Major improvements in vector targeting technology are required before any clinical success. On this basis, this thesis tests the hypothesis to target transformed tumor cells by using a novel posttranslational mRNA stabilizing mechanism, which is occasionally deregulated in cancer. The overexpression of various proteins associated with rapid responses to inflammation and/or proliferation can be controlled at the level of mRNA stability. Since tumor cells continually recapitulate intracellular programs of proliferation, we hypothesize that we can use the tumor cell selective stabilization of mRNA as a novel means to target different malignant diseases. Cyclooxygenase (COX) is the key enzyme in the conversion of arachidonic acid to prostaglandin during inflammation and many studies have linked elevated expression of COX-2 to the pathology of breast, colorectal, head and neck and other types of cancer. It has been shown that the up-regulation of COX-2 is a downstream effect of RAS-mediated transformation. Although the COX-2 over-expression in cancer is associated with increased transcription of the COX-2 gene, a large component of RAS-induced upregulation is also mediated by a selective stabilization of the mRNA of the COX-2 gene in RAS-transformed cells. In this project, we show tumor selective mRNA stability via COX-2 3’ UTR by fusing it with the adenovirus early essential gene E1A, thereby obtaining a conditionally replicating adenovirus vector which will preferentially replicate in the RAS transformed cells. There are wide range of genes reported in the literature with 3'UTR, which confers destabilized activity on their cognate mRNA, but whose actions are reversed under certain physiological conditions. These include hypoxia responsive 3'UTR, radiation responsive elements and 3' UTR, which mediate increased mRNA stability in proliferating cells. Therefore, the linkage to 3’UTRs is a general strategy that could be used to confer tumor cell specificity to expression of therapeutic and/or replicative genes in a wide variety of vectors and to target specific physiological situations within tumors.
Spurious Point Source Signals in the Galactic Center Excess

description: We re-examine evidence that the Galactic Center Excess (GCE) originates primarily from point sources (PSs). We show that in our region of interest, non-Poissonian template fitting (NPTF) evidence for GCE PSs is an artifact of unmodeled north-south asymmetry of the GCE. This asymmetry is strongly favored by the fit (although it is unclear if this is physical), and when it is allowed, the preference for PSs becomes insignificant. We reproduce this behavior in simulations, including detailed properties of the spurious PS population. We conclude that NTPF evidence for GCE PSs is highly susceptible to certain systematic errors, and should not at present be taken to robustly disfavor a dominantly smooth GCE.

description: The Galactic Center GeV excess (GCE) has garnered great interest as a possible signal of either dark matter annihilation or some novel astrophysical phenomenon, such as a new population of gamma-ray emitting pulsars. In a companion paper, we showed that in a $10^\circ$ radius region of interest (ROI) surrounding the Galactic Center, apparent evidence for GCE point sources (PSs) from non-Poissonian template fitting (NPTF) is actually an artifact of unmodeled north-south asymmetry of the GCE. In this work, we develop a simplified analytic description of how signal mismodeling can drive an apparent preference for a PS population, and demonstrate how the behavior pointed out in the companion paper also appears in simpler simulated datasets that contain no PS signals at all. We explore the generality of this behavior in the real gamma-ray data, and discuss the implications for past and future studies using NPTF techniques. While the drop in PS preference once north-south asymmetry is included is not ubiquitous in larger ROIs, we show that any overly-rigid signal model is expected to yield a spurious PS signal that can appear very convincing: as well as apparent significance comparable to what one would expect from a true PS population, the signal can exhibit stability against a range of variations in the analysis, and a source count function that is very consistent with previous apparent NPTF-based detections of a GCE PS population. This contrasts with previously-studied forms of systematic mismodeling which are unlikely to mimic a PS population in the same way. In the light of this observation, and its explicit realization in the region where the GCE is brightest, we argue that a dominantly smooth origin for the GCE is not in tension with existing NPTF analyses.

description: This workshop has been organised by the Community of Practice for Training Coordinators. RDM training and support has been identified as a major challenge in many organisations. Increasingly resources are invested in data steward teams to take up the task of training researchers. Naturally data stewards must also be trained to take up the job at hand. Many materials are produced to support professional development and train-the-trainer activities for researchers, data stewards and others involved in enabling FAIR and Open research. Many European funded projects have developed catalogues or intend to do so, sometimes with a particular discipline or profile in mind. They each have their peculiarities but encounter similar challenges and decisions to make. In the EOSC context a catalogue of catalogues has been proposed by the Training and Skills WG, to improve FAIRness of training materials. Building on two previous events organised by INFRAEOSC-5 projects, and ongoing collaboration with the Research Data Alliance (RDA) interest group on Education and Training in Handling Research Data (IG ETHRD), this workshop will help consolidate further steps to improve sustainability of catalogues, and their technical and semantic interoperability. In this workshop we aim to describe and compare several catalogues developed. We will investigate solutions to interact and we will formulate advice on how to proceed in the future to sustainably catalogue the training resources needed for researchers and data stewards to make digital research objects that are FAIR and open. The Workshop recording is available here and the blog is published as part of the OpenAIRE website

description: We present a new method for nonlinear prediction of discrete random sequences under minimal structural assumptions. We give a mathematical construction for optimal predictors of such processes, in the form of hidden Markov models. We then describe an algorithm, CSSR (Causal-State Splitting Reconstruction), which approximates the ideal predictor from data. We discuss the reliability of CSSR, its data requirements, and its performance in simulations. Finally, we compare our approach to existing methods using variable-length Markov models and cross-validated hidden Markov models, and show theoretically and experimentally that our method delivers results superior to the former and at least comparable to the latter.

In the Beautiful Waters
Creators: name: Scanlan, Margaret
Publisher: name: American University
Year: 2023

description: In the Beautiful Waters is about a journey. The journey begins, as journeys do, with a leaving and ends with a coming home; it encompasses new places and experiences, but primarily involves putting old places and experiences into a new perspective. The poems are about love and hate, the ties that bind; life, pain, death, and memory, which is the stuff of poetry; and about art and old stories. The dominant images throughout the collection are water and night, and the poems show a combination, which some call Celtic, of dark wit and lyric sensibility in tension with one another. The poems often have a formal structure, but most are in free verse.
