description: A Hamiltonian and action principle formalism for deriving three-dimensional gyroviscous magnetohydrodynamic models is presented. The uniqueness of the approach in constructing the gyroviscous tensor from first principles and its ability to explain the origin of the gyromap and the gyroviscous terms are highlighted. The procedure allows for the specification of free functions, which can be used to generate a wide range of gyroviscous models. Through the process of reduction, the noncanonical Hamiltonian bracket is obtained and briefly analysed.

description: Research Data Management (RDM) platforms play an important role in todays research ecosystem to disseminate and archive, enable reproducibility, and empower reuse. RDM platforms allow researchers to share and preserve scientific results and support the sharing of a wide variety of resources, from publications and presentations to datasets, software, policy documents, and workflows. Research funding agencies around the world have also recognized the huge potential economic and social benefits of RDMs and support their use in research preservation and dissemination. CERN has partnered with 10 international multidisciplinary institutions and companies to build a turn-key open source research data management platform called Invenio RDM, and grow a diverse community to sustain the platform. We seek to make Invenio RDM a world-leading extensible research data management platform used by research institutions all around the world and with businesses providing services, support and customizations on top of Invenio RDM. Invenio RDM includes existing Zenodo features, such as DOI minting capabilities, versioning support, and COUNTER compliant usage statistics, to name a few. Transforming Zenodo into a general purpose RDM-platform will focus on improvements to the core repository (especially to support next-generation repository standards), packaging and distribution to support easy implementation, and customization and extendability. This presentation will provide an update to the community about this work, describe our development roadmap, share interdisciplinary key use cases for this work, and gather real-time audience input.This work is supported by the CERN Knowledge Transfer Fund; participating partners (to date) include: Brookhaven National Laboratory, Caltech Library, Data Futures, Helmholtz Zentrum Dresden-Rossendorf, Northwestern University, OpenAIRE, TIND, Tubitak, Universitat Hamburg, and the University of Munster; and the NIH National Center for Advancing Translational Sciences, Grant Number U24TR002306, to the US Center for Data to Health (CD2H).

description: Purpose: The importance of routine, physical activity on healthy development during the early years is widely acknowledged. The purpose of this pilot study was to conduct a process evaluation exploring Early Childhood Educators’ (ECEs’) perspectives of the feasibility and appropriateness of an evidence-informed, 8-item institutional-level policy document targeting children’s physical activity, outdoor play, and sedentary behavior. Methods: A cluster, randomized controlled trial with 9 childcare centres in London, Ontario was conducted. Centres in the intervention condition (n = 5) implemented the evidence-based policy for 8 weeks. Intervention group ECEs (n= 22) recorded their daily compliance with the written policy in implementation logs for the duration of the intervention. Additionally, program evaluation surveys (n = 21) and interviews (n = 10) were completed post-intervention to assess barriers/facilitators, feasibility, enjoyment, and likelihood of future implementation. Descriptive statistics and thematic analysis were conducted. Results: ECEs perceived the PLAY intervention to be both enjoyable and effective at increasing preschoolers' physical activity. Adherence to policy items ranged from 16.5% (for delivery of shorter, more frequent outdoor periods) to 85.9% (for delivery of unstructured/child-directed play). ECEs reported their likelihood to continue implementing policy components, excluding frequent outdoor periods (0 = not at all likely to 5 = extremely likely; M = 2.19; SD = 1.21). Results from the program evaluation survey showed ECEs found the policy to be appropriate for implementation in childcare settings. Barriers to implementing the policy included extreme weather, difficulty with transitions, and lack of physical activity-related training. Providing verbal prompts and engaging in activity alongside children were noteworthy solutions. Conclusion: The results of this study demonstrate the feasibility of a physical activity and sedentary time policy from an ECE lens. Findings from this process evaluation indicate that ECE’s found the policy feasible for implementing in centre-based childcare. Additional investigation is needed to explore how such a policy can be modified for future use.

description: Data from the HERA collider experiments, H1 and ZEUS, have been fundamental to the rapid recent development of our understanding of the partonic composition of the proton and of QCD. This report focuses on inclusive measurements of neutral and charged current cross sections at HERA, using the full available data taken to date. The present precision on the proton parton densities and the further requirements for future measurements at the Tevatron and LHC are explored. Emphasis is also placed on the region of very low Bjorken-x and Q^2. In this region, the `confinement' transition takes place from partons to hadrons as the relevant degrees of freedom and novel or exotic QCD effects associated with large parton densities are most likely to be observed. Finally, prospects for the second phase of HERA running are discussed.

description: This paper reports on study which employed the travel cost method of estimating economic values from low streamflow augmentation for whitewater angling and boating. In addition, we constructed a dynamic programming (DP) model which allows a water management agency to optimally time instream flow augmentations of a seasonally fixed water supply in the face of uncertain future natural streamflows. The model was applied to a case study of the wild river stretch of New Mexico's Rio Chama. Results indicate that properly timed streamflow augmentation can yield benefits of up to $1100 per consumptive acre foot, as compared to agricultural values of $50 per acre foot. Hence, results strongly suggest the economic feasibility of public acquisition of water rights for instream flow augmentation.

On the Einstein relation in a heated granular gas

description: Recent computer simulation results [Barrat {\em et al.}, Physica A 334 (2004) 513] for granular mixtures subject to stochastic driving have shown the validity of the Einstein relation $ε\equiv D/(T_0λ)=1$ between the diffusion $D$ and mobility $λ$ coefficients when the temperature of the gas $T$ is replaced by the temperature of the impurity $T_0$ in the usual Einstein relation. This problem is analyzed in this paper by solving analytically the Boltzmann-Lorentz equation from the Chapman-Enskog method. The gas is heated by the action of an external driving force (thermostat) which does work to compensate for the collisional loss of energy. Two types of thermostats are considered: (a) a deterministic force proportional to the particle velocity (Gaussian thermostat), and (b) a white noise external force (stochastic thermostat). The diffusion and mobility coefficients are given in terms of the solutions of two linear integral equations, which are approximately solved up to the second order in a Sonine polynomial expansion. The results show that the violation of the Einstein relation ($ε\neq 1$) is only due to the non-Maxwellian behavior of the impurity velocity distribution function (absence of the Gibbs state). At a quantitative level, the kinetic theory results also show that the deviation of $ε$ from 1 is more significant in the case of the Gaussian thermostat than in the case of the stochastic one, in which case the deviation of the Einstein relation is in general smaller than 1%. This conclusion agrees quite well with the results found in computer simulations.

description: Innovations in annotation methodology have been a catalyst for Reading Comprehension (RC) datasets and models. One recent trend to challenge current RC models is to involve a model in the annotation process: humans create questions adversarially, such that the model fails to answer them correctly. In this work we investigate this annotation methodology and apply it in three different settings, collecting a total of 36,000 samples with progressively stronger models in the annotation loop. This allows us to explore questions such as the reproducibility of the adversarial effect, transfer from data collected with varying model-in-the-loop strengths, and generalisation to data collected without a model. We find that training on adversarially collected samples leads to strong generalisation to non-adversarially collected datasets, yet with progressive performance deterioration with increasingly stronger models-in-the-loop. Furthermore, we find that stronger models can still learn from datasets collected with substantially weaker models-in-the-loop. When trained on data collected with a BiDAF model in the loop, RoBERTa achieves 39.9F1 on questions that it cannot answer when trained on SQuAD - only marginally lower than when trained on data collected using RoBERTa itself (41.0F1).

description: A geometric formalism is developed which allows to describe the non-linear regime of higher-spin gravity emerging on a cosmological quantum space-time in the IKKT matrix model. The vacuum solutions are Ricci-flat up to an effective vacuum energy-momentum tensor quadratic in the torsion, which arises from a Weitzenböck-type higher spin connection. Torsion is expected to be significant only at cosmic scales and around very massive objects, and could behave like dark matter. A non-linear equation for the torsion tensor is found, which encodes the Yang-Mills equations of the matrix model. The metric and torsion transform covariantly under a higher-spin generalization of volume-preserving diffeomorphisms, which arises from the gauge invariance of the matrix model.

description: UBC Food Services play a role in mitigating food insecurity while promoting social, economic, and environmental sustainability through their newly established Food Vision and Values. However, they currently have no way of tracking how well their operations align with their vision and values. Our research goals were to 1) help develop a dynamic auditing tool in the form of a spreadsheet to measure how well operations align with the Food Vision and Values and 2)conduct 2 in-person audits to provide baseline data for populating the spreadsheet. We choseto do the audits on the Vegan & Vegetarian Options at UBC’s Open Kitchen dining hall and Free Drinking Water values at 33 UBC Food Services locations based on stakeholder priority and group availability. The forms used in both audits derived from their respective sheets as part of our auditing spreadsheet. The Free Drinking Water audit was conducted by dividing the UBCFS locations according to geographical distribution and having each group member audit all the locations in one section. The Vegan & Vegetarian Options were audited as a group by going to each station at Open Kitchen to note the available menu offerings at the time. Less than half of the audited UBCFS locations had a water station and the ratio of stations with signage, compared to without signage, is 7:8. Our audit results show that there were 4 food locations that did not meet the UBCFS standard to provide access to free drinking water. Out of the 42 entrées at Open Kitchen, 43% were categorized as vegetarian, while 17% were vegan, and 14% incorporated plant based proteins. Main recommendations to UBC Food Services to help improve their operations include: 1) inform the presence of FDW either through increased signage, menu display or directions to water stations, 2) increase the number of Vegan/Vegetarian entrée offerings and 3) inform the presence of such offerings using appropriate signage.

description: Upon consulting the dictionary we find that a hobby is "something in which one takes absorbing interest." A survey of the literature of hobbies and hobbyists leads one to deduce a rough categorization of the hobbyists into the following types: the collectors, the doers, and the scholars. The types are overlapping, but each has its special characteristics. The "collectors" seem to be born with an instinctive passion for assembling things, and in the progressive stages of their hobbying, the passion becomes organizational. The "doers" seem possessed of a creative, manipulative impulse which impells them to activity. Their hobbies progress artistically towards the idealization of beauty and form. The "scholars" seek truth and understanding. Their interests are computative, intellectual, and abstract. The purpose of this thesis is to review the relationships and interrelationships of curricular and administrative problems to the objective of furthering and improving these hobby types.

description: We use the halo model of clustering to compute two- and three-point correlation functions for weak lensing, and apply them in a new statistical technique to measure properties of massive halos. We present analytical results on the eight shear three-point correlation functions constructed using combination of the two shear components at each vertex of a triangle. We compare the amplitude and configuration dependence of the functions with ray-tracing simulations and find excellent agreement for different scales and models. These results are promising, since shear statistics are easier to measure than the convergence. In addition, the symmetry properties of the shear three-point functions provide a new and precise way of disentangling the lensing E-mode from the B-mode due to possible systematic errors. We develop an approach based on correlation functions to measure the properties of galaxy-group and cluster halos from lensing surveys. Shear correlations on small scales arise from the lensing matter within halos of mass M > 10^13 solar masses. Thus the measurement of two- and three-point correlations can be used to extract information on halo density profiles, primarily the inner slope and halo concentration. We demonstrate the feasibility of such an analysis for forthcoming surveys. We include covariances in the correlation functions due to sample variance and intrinsic ellipticity noise to show that 10% accuracy on profile parameters is achievable with surveys like the CFHT Legacy survey, and significantly better with future surveys. Our statistical approach is complementary to the standard approach of identifying individual objects in survey data and measuring their properties.

The Uncertainty in Newton's Constant and Precision Predictions of the Primordial Helium Abundance
Creators: name: Scherrer, Robert J.
Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The current uncertainty in Newton's constant, G_N, is of the order of 0.15%. For values of the baryon to photon ratio consistent with both cosmic microwave background observations and the primordial deuterium abundance, this uncertainty in G_N corresponds to an uncertainty in the primordial 4He mass fraction, Y_P, of +-1.3 x 10^{-4}. This uncertainty in Y_P is comparable to the effect from the current uncertainty in the neutron lifetime, which is often treated as the dominant uncertainty in calculations of Y_P. Recent measurements of G_N seem to be converging within a smaller range; a reduction in the estimated error on G_N by a factor of 10 would essentially eliminate it as a source of uncertainty in the calculation of the primordial 4He abundance.

description: Diamond quantum processors consisting of a nitrogen-vacancy (NV) centre and surrounding nuclear spins have been the key to significant advancements in room-temperature quantum computing, quantum sensing and microscopy. The optimisation of these processors is crucial for the development of large-scale diamond quantum computers and the next generation of enhanced quantum sensors and microscopes. Here, we present a full model of multi-qubit diamond quantum processors and develop a semi-analytical method for designing gate pulses. This method optimises gate speed and fidelity in the presence of random control errors and is readily compatible with feedback optimisation routines. We theoretically demonstrate infidelities approaching $\sim 10^{-5}$ for single-qubit gates and established evidence that this can also be achieved for a two-qubit CZ gate. Consequently, our method reduces the effects of control errors below the errors introduced by hyperfine field misalignment and the unavoidable decoherence that is intrinsic to the processors. Having developed this optimal control, we simulated the performance of a diamond quantum processor by computing quantum Fourier transforms. We find that the simulated diamond quantum processor is able to achieve fast operations with low error probability.
description: Published version. Updated references, additional analysis for the infidelities of CZ gate. Two new appendices on discussing the effects of time-ordering in the quantum evolution and examining the effects of the secular approximation and hyperfine field misalignments on gate fidelities.

description: The problem of distributed synthesis is to automatically generate a distributed algorithm, given a target communication network and a specification of the algorithm's correct behavior. Previous work has focused on static networks with an a priori fixed message size. This approach has two shortcomings: Recent work in distributed computing is shifting towards dynamically changing communication networks rather than static ones, and an important class of distributed algorithms are so-called full-information protocols, where nodes piggy-pack previously received messages onto current messages. In this work, we consider the synthesis problem for a system of two nodes communicating in rounds over a dynamic link whose message size is not bounded. Given a network model, i.e., a set of link directions, in each round of the execution, the adversary choses a link from the network model, restricted only by the specification, and delivers messages according to the current link's directions. Motivated by communication buses with direct acknowledge mechanisms, we further assume that nodes are aware of which messages have been delivered. We show that the synthesis problem is decidable for a network model if and only if it does not contain the empty link that dismisses both nodes' messages.

description: We obtain solutions of the three dimensional Dirac equation for radial power-law potentials at rest mass energy as an infinite series of square integrable functions. These are written in terms of the confluent hypergeometric function and chosen such that the matrix representation of the Dirac operator is tridiagonal. The "wave equation" results in a three-term recursion relation for the expansion coefficients of the spinor wavefunction which is solved in terms of orthogonal polynomials. These are modified versions of the Meixner-Pollaczek polynomials and of the continuous dual Hahn polynomials. The choice depends on the values of the angular momentum and the power of the potential.

Efforts are underway to standardize the structure and content of DMPs and DAS at both technical and policy levels. In this session you will hear from four key stakeholder groups regarding their approaches towards addressing challenges and opportunities in DMPs and DAS: Dutch Research Council (NWO) - Champions research data management policy alignment with research funders in Europe. One of the first organizations to implement Science Europe core requirements for DMPs, NWO actively promotes these requirements to other stakeholders. American Geophysical Union (AGU) - Advances data/software sharing policies and approaches in publishing through a broad coalition of partners and stakeholders. Beginning with its position statement on data (1997), AGU continues to improve its guidance and move towards machine-actionable DAS and research articles. Research Data Alliance (RDA) DMP Common Standards Working Group (WG) – Develops a community-wide information model, as well as specifications and access mechanisms for machine-actionable DMPs (maDMPs). The WG recently released its maDMP recommendations for fostering greater collaboration, integration, and automation of maDMPs across research workflows. Argos - An open extensible service through OpenAire that simplifies the management, validation, monitoring and maintenance of DMPs. Argos constructs DMPs as machine-actionable outputs that are also shared through Zenodo according to Open and FAIR practices. Furthermore, the Argos paradigm inspires discussions and solutions towards the automation, linking, and machine-actionability of DAS and DMPs.

Some administrative aspects of a hobby program for an American elementary school
Creators: name: Yoder, Dorothy Grey
Publisher: name: American University
Year: 2023

description: Upon consulting the dictionary we find that a hobby is "something in which one takes absorbing interest." A survey of the literature of hobbies and hobbyists leads one to deduce a rough categorization of the hobbyists into the following types: the collectors, the doers, and the scholars. The types are overlapping, but each has its special characteristics. The "collectors" seem to be born with an instinctive passion for assembling things, and in the progressive stages of their hobbying, the passion becomes organizational. The "doers" seem possessed of a creative, manipulative impulse which impells them to activity. Their hobbies progress artistically towards the idealization of beauty and form. The "scholars" seek truth and understanding. Their interests are computative, intellectual, and abstract. The purpose of this thesis is to review the relationships and interrelationships of curricular and administrative problems to the objective of furthering and improving these hobby types.
Mode Softening near the critical point within effective approaches to QCD

description: We study the soft mode along the critical line in the phase diagram with the tricritical point, using the Nambu--Jona-Lasinio model. At the critical point with finite quark mass, the ordering density becomes a linear combination of the scalar, quark number and energy densities, and their susceptibilities diverge with the same exponent. Based on the conservation law, it is argued that the divergent susuceptibility of a conserved density must be accompanied by a critically--slowing hydrodynamic mode. The shift of the soft mode from the sigma meson to the hydrodynamic mode occurs at the tricritical point on the critical line.

description: Concolic execution and fuzzing are two complementary coverage-based testing techniques. How to achieve the best of both remains an open challenge. To address this research problem, we propose and evaluate Legion. Legion re-engineers the Monte Carlo tree search (MCTS) framework from the AI literature to treat automated test generation as a problem of sequential decision-making under uncertainty. Its best-first search strategy provides a principled way to learn the most promising program states to investigate at each search iteration, based on observed rewards from previous iterations. Legion incorporates a form of directed fuzzing that we call approximate path-preserving fuzzing (APPFuzzing) to investigate program states selected by MCTS. APPFuzzing serves as the Monte Carlo simulation technique and is implemented by extending prior work on constrained sampling. We evaluate Legion against competitors on 2531 benchmarks from the coverage category of Test-Comp 2020, as well as measuring its sensitivity to hyperparameters, demonstrating its effectiveness on a wide variety of input programs.

description: Background: Moderate-to-vigorous physical activity (MVPA) provides preschoolers (2.5-5y) with many health benefits, and at childcare time spent this behaviour is primarily accrued outdoors. Purpose: The purpose of this cross-sectional analysis of the Supporting Physical Activity in the Childcare Environment (SPACE) study was to examine the influence of varying outdoor play schedules (2 x 60-minute versus 4 x 30-minute sessions) on preschoolers’ activity levels outdoors. Methods: Preschoolers wore an Actical accelerometer for 5 days during childcare for the final week of the SPACE intervention; outdoor times were logged by staff. Separate linear mixed effects models were performed to assess the effect of the SPACE intervention on preschoolers’ outdoor physical activity (total, MVPA) and sedentary time, with sex entered as an interaction effect. Results: Preschoolers (n = 292) were significantly more active within the first 10 minutes of outdoor play compared with remaining time (p < .0083). Across total outdoor time, preschoolers in the experimental group were significantly less sedentary than those in the control group (p < .017), and boys and girls in the experimental group engaged in greater MVPA than their counterparts in the control group (p < .017). Conclusions: Findings provide support for scheduling shorter, more frequent outdoor play periods to increase physical activity and decrease sedentary time among preschoolers.

description: We study the action of the mapping class group of an oriented genus g surface with n punctures and a disc removed on a Poisson algebra which arises in the combinatorial description of Chern-Simons gauge theory when the gauge group is a semidirect product $G\ltimes\mathfrak{g}^*$. We prove that the mapping class group acts on this algebra via Poisson isomorphisms and express the action of Dehn twists in terms of an infinitesimally generated G-action. We construct a mapping class group representation on the representation spaces of the associated quantum algebra and show that Dehn twists can be implemented via the ribbon element of the quantum double D(G) and the exchange of punctures via its universal R-matrix.

description: The postwar period has been a period of drastic changes for the Asian and African countries. For them it has become the dawn of a new era, the beginning of the end of foreign domination and control and the start of a new life. However, after centuries of foreign rule and colonial exploitation, these countries are economically and technologically underdeveloped. Consequently, many problems must be faced such as the undertaking of economic improvements and establishment of educational standards.

description: This workshop will be co-organised by LIBER and Open Research Europe (ORE). Open Research Europe is an open access publication platform for the publication of research resulting from Horizon 2020 and Horizon Europe funding in all subject areas. The workshop will explain the peer review model behind the platform which is fully open and transparent as well as invite expert speakers to talk about innovative peer review. Recently, increasing attention has been paid to ways of streamlining the peer review process and applying alternative peer review methods using new technologies and open access models. There are several developments that the world of scientific communication is currently facing in relation to these new processes and methods such as finding a balance between speeding up the process without compromising quality, integration with research evaluation and understanding the role of citizens and machines in peer review. The new developments in the field of Innovative Peer Review can lead to great opportunities for research libraries, especially in the areas of service development, engagement, and training. During the workshop best practices will be shared about new open peer review approaches, with the opportunity to discuss these new developments in a group discussion. The workshop is addressed at research librarians and researchers with and without experience with the ORE platform with an interest in open and innovative peer review. Specifically, research libraries professionals in publishing and editorial units, or managers of advanced repositories and library staff who work on Open Science software, or who are responsible for promoting Open Science in their institutions are invited to join.

description: Random Feature (RF) models are used as efficient parametric approximations of kernel methods. We investigate, by means of random matrix theory, the connection between Gaussian RF models and Kernel Ridge Regression (KRR). For a Gaussian RF model with $P$ features, $N$ data points, and a ridge $λ$, we show that the average (i.e. expected) RF predictor is close to a KRR predictor with an effective ridge $\tildeλ$. We show that $\tildeλ > λ$ and $\tildeλ \searrow λ$ monotonically as $P$ grows, thus revealing the implicit regularization effect of finite RF sampling. We then compare the risk (i.e. test error) of the $\tildeλ$-KRR predictor with the average risk of the $λ$-RF predictor and obtain a precise and explicit bound on their difference. Finally, we empirically find an extremely good agreement between the test errors of the average $λ$-RF predictor and $\tildeλ$-KRR predictor.
