Galaxy and research lifecycle management technologies for earth science communities and Copernicus users in EOSC
Creators: name: Fouilloux, Anne
name: Iaquinta, Jean
Publisher: name: F1000 Research Limited
Year: 2021

description: The main objective of RELIANCE (https://www.reliance-project.eu/) is to provide Earth Scientists and Copernicus user communities with an innovative and interoperable service portfolio offering for an open-by-default, efficient, and crossdisciplinary research management environment supporting FAIR data principles and Open Science.
 Copernicus is the European Union's Earth observation programme, providing information services that draw from satellite Earth Observation and in-situ (non-space) data. This wealth of information is aimed at being exploited by everyone, for the benefit of all citizens but accessing Copernicus data is difficult and often requires advanced programming skills. By offering access to Copernicus data in Galaxy and deploying Galaxy tools for analyzing and creating advanced workflows, we believe it will democratize the usage of such data and facilitate cross-disciplinary research. RELIANCE service ecosystem (Research Objects, Data Cubes and AI-based Text Mining) will be "connected" to Galaxy to facilitate the re-use of generated Research Objects from Galaxy.
 During GCC2021, we will present the current status and the roadmap.

description: Recently, Neubert has suggested that a certain class of nonperturbative corrections dominates the shape of the electron spectrum in the endpoint region of semileptonic $B$ decay. Perturbative QCD corrections are important in the endpoint region. We study the effects of these corrections on Neubert's proposal. The connection between the endpoint of the electron spectrum in semileptonic $B$ decay and the photon spectrum in $b\rightarrow sγ$ is outlined.

description: This article considers the realm of knowledge in early childhood education (ECE); what knowledge is valued, and how different types of knowledge position children and educators. To this end, two different examples of practice informed by different types of knowledge are provided: one from an educator working in a long day care service (Duncan) and a second, a national assessment of young children’s development, the Australian Early Development Census (AEDC). The two examples reflect practices that one might see in Australian ECE settings, and due to governance and regulations, both illustrations could be evident in the same context. Using a dialogic approach we provide an insight into the requirements of the everyday work of educators and the disparate and often irreconcilable understandings of knowledge that inform their everyday work. We conclude with some suggestions for more equitable approaches and identify some of the challenges of attempting to do this.
Ruijsenaars-Schneider three-body models with N=2 supersymmetry

description: The Ruijsenaars-Schneider models are conventionally regarded as relativistic generalizations of the Calogero integrable systems. Surprisingly enough, their supersymmetric generalizations escaped attention. In this work, N=2 supersymmetric extensions of the rational and hyperbolic Ruijsenaars-Schneider three-body models are constructed within the framework of the Hamiltonian formalism. It is also known that the rational model can be described by the geodesic equations associated with a metric connection. We demonstrate that the hyperbolic systems are linked to non-metric connections.

We find that the $k^2$-dependence of the multipole $L_{0+}^{(+)}$ at threshold is given by the nucleon scalar form factor, namely $σ(k^2-M_π^2 ) /(3 πM_πF_π)$. The relation to PCAC results for soft pions including electroweak form factors is also clarified.

description: We are interested in the consistency between the cutoff, chiral symmetry, and the power counting. For this purpose, we apply the Wilsonian renormalization group (RG) to an operator and then decrease the Wilsonian cutoff. As an example, we study the s-wave pion production operator for NN\to dπ, derived in chiral perturbation theory. We find that the renormalized part of the RG effective operator is accurately absorbed by chiral counter terms of higher order with natural coefficients. Thus, the use of the (sharp) cutoff regularization does not require us to introduce chiral-symmetry-breaking counter terms, at least in the case of the NN\to dπreaction.

subject: imbalanced learning

description: Type 1 diabetes (T1D) is a chronic disease that requires those who live with it to regularly administer exogenous insulin to maintain blood glucose (BG) within a safe range. Insufficient insulin dosing can cause high glucose, leading to complications such as diabetic retinopathy, neuropathy, and cardiomyopathy. Too much insulin can cause low glucose, and when untreated, lead to coma or death. T1D-related complications can be reduced with proper diet, exercise, and adherence to an insulin dosing regimen. Decision support systems (DSS) can also help optimize glucose management by utilizing artificial intelligence (AI) and physician expertise to suggest adjustments to therapy parameters and behavior. However, a lack of explainability in a DSS’s suggested changes may deter participants from understanding and following AI-generated recommendations. In addition, manual calculation of meal insulin is still required by the participant. Incorrect dosing of meal insulin is common due to human error in estimating carbohydrate amounts in foods which can lead to poor postprandial glucose outcomes. Fats and proteins have also been observed to affect postprandial glucose response (PPGR) and these are typically not considered when estimating mealtime insulin.
This work begins with background on diabetes management and a discussion of the complexity of nutritional influences on PPGR, extending beyond carbohydrates to include fats and proteins. In the second chapter, an 8-week randomized controlled study of a real-world DSS is discussed. Mixed effects models revealed that time-in range was improved by an average of 6.3% (P=0.001, CI 2.5%-10.1%) when participants accepted and followed system recommendations. In the third chapter, machine learning (ML) algorithms are trained to predict three components of PPGR: net area under the curve (netAUC), minimum BG (minBG), and maximum BG (maxBG).
Predictions of balanced random forest (RF) algorithms are combined with those of standard RF via regression models to reduce bias. While systemic bias remains, final predictions are highly
viii
correlated with observations for netAUC, minBG, and maxBG (R=0.62, R=0.61, R=0.7). Feature importance reveals that past BG measurements, BG trend, and insulin on board primarily influence the PPGR and macronutrient contents were less relevant. Finally, in the fourth chapter, future DSS integrations with PPGR models are discussed. Future PPGR modeling may help DSS users calculate the appropriate amount of meal insulin, provide explainability to bolus calculations, and help guide individuals towards dietary choices that optimize PPGR.

Subjects: subject: Astrophysics (astro-ph)

description: In low-mass Red Giant Branch (RGB) and Asymptotic Giant Branch (AGB) stars, anomalous mixing must transport material near the hydrogen-burning shell to the convective envelope. Recently, it was suggested that buoyant magnetic flux tubes could supply the necessary transport rate (Busso et al. 2007). The fields are assumed to originate from a dynamo operating in the stellar interior. Here, we show what is required of an $α-Ω$ dynamo in the envelope of an AGB star to maintain these fields. Differential rotation and rotation drain via turbulent dissipation and Poynting flux, so if shear can be resupplied by convection, then large-scale toroidal field strengths of $\left\simeq3\times10^4$ G can be sustained at the base of the convection zone.

Embedding A4 into left-right flavor symmetry: Tribimaximal neutrino mixing and fermion hierarchy

Year: 2007

description: We address two fundamental aspects of flavor physics: the mass hierarchy and the large lepton mixing angles. On one side, left-right flavor symmetry realizes the democratic mass matrix patterns and explains why one family is much heavier than the others. On the other side, discrete flavor symmetry such as A4 leads to the observed tribimaximal mixing for the leptons. We show that, by explicitly breaking the left-right flavor symmetry into the diagonal A4, it is possible to explain both the observed charged fermion mass hierarchies and quark and lepton mixing angles. In particular we predict a heavy 3rd family, the tribimaximal mixing for the leptons, and we suggest a possible origin of the Cabibbo and other mixing angles for the quarks.

The limits imposed by this process on deviations from the standard model of electro-weak interaction, are competitive with those inferred from other high energy experiments. Furthermore, the allowed domain in the parameter space is quite different, and hence such an experiment would more than complement the other direct searches.

description: In this paper, we consider the dynamics of solutions to complex-valued evolutionary partial differential equations (PDEs) and show existence of heteroclinic orbits from nontrivial equilibria to zero via computer-assisted proofs. We also show that the existence of unbounded solutions along unstable manifolds at the equilibrium follows from the existence of heteroclinic orbits. Our computer-assisted proof consists of three separate techniques of rigorous numerics: an enclosure of a local unstable manifold at the equilibria, a rigorous integration of PDEs, and a constructive validation of a trapping region around the zero equilibrium.

For the resolved conifold this function turns out to be the quantum Barnes function, a natural $q$-deformation of the classical one that in its turn generalizes Euler's gamma function. Our reasoning is based on a new formula for this function that expresses it as a graded product of $q$-shifted multifactorials.

Probing isovector scalar mesons in the charmless three-body $B$ decays

description: We propose to study the multiparticle configurations of isovector scalar mesons, saying $a_0(980)$ and $a_0(1450)$, in the charmless three-body $B$ decays by considering the width effects. Two scenarios of $a_0$ configurations are assumed, in which the first one take $a_0(980)$ as the lowest-lying $q{\bar q}$ state and $a_0(1450)$ as the first radial excited state, the second one take $a_0(1450)$ as the lowest-lying $q{\bar q}$ state and $a_0(1950)$ as the first radial excited state while $a_0(980)$ is not a $q{\bar q}$ state. Within these two scenarios, we do the PQCD calculation for the quasi-two-body $B \to a_0 \left[\to K{\bar K}/πη\right] h$ decays and extract the corresponding branching fractions of two-body $B \to a_0 h$ decays under the narrow width approximation. Our predictions show that the first scenario of $a_0(980)$ configuration can not be excluded by the available measurements in $B$ decays, the contributions from $a_0(1450)$ to the branching fractions in most channels are comparable in the first and second scenarios. Several channels are suggested for the forthcoming experimental measurements to reveal the multiparticle configurations of $a_0$, such as the channel $B^0 \to a_0^-(980) \left[\to π^-η\right] π^+$ with the largest predicted branching fraction, the channels $B^0 \to a_0^{\pm}(1450) \left[\to K^\pm{\bar K}^0, π^\pmη\right] π^\mp$ whose branching fractions obtained in the second scenario is about three times larger in magnitude than that obtained in the first scenario, and also the channels $B^+ \to a_0^+(1950) \left[ K^+{\bar K}^0/π^+η\right] K^0$ whose branching fractions are linear dependent on the partial width $Γ_{a_0(1950) \to KK/πη}$.

Exchange biasing of single-domain Ni nanoparticles spontaneously grown in an antiferromagnetic MnO matrix

description: Exchange biased composites of ferromagnetic single-domain Ni nanoparticles embedded within large grains of MnO have been prepared by reduction of Ni$_x$Mn$_{1-x}$O$_4$ phases in flowing hydrogen. The Ni precipitates are 15-30 nm in extent, and the majority are completely encased within the MnO matrix. The manner in which the Ni nanoparticles are spontaneously formed imparts a high ferromagnetic- antiferromagnetic interface/volume ratio, which results in substantial exchange bias effects. Exchange bias fields of up to 100 Oe are observed, in cases where the starting Ni content $x$ in the precursor Ni$_x$Mn$_{1-x}$O$_4$ phase is small. For particles of approximately the same size, the exchange bias leads to significant hardening of the magnetization, with the coercive field scaling nearly linearly with the exchange bias field.

description: This is the pre-published version harvested from ArXiv. The published version is located at http://iopscience.iop.org/1538-4357/561/1/L107/
description: We report on the first detection of presupernova evolution in the X-ray regime. The results are based on ROSAT observations of SN 1993J ranging from 6 days to 5 years after the outburst. The X-ray observations are used to probe the SN shell interaction with the ambient circumstellar matter (CSM). After exploring various scenarios that might explain the observed X-ray light curve with a t-0.27 rate of decline, we present a coherent picture in terms of the interaction of the SN shock front with the CSM deposited by the progenitor's stellar wind. During the observed period, the SN shell reaches a radius of 3 × 1017 cm from the site of the explosion, corresponding to ~104 yr in the progenitor's stellar wind history. Our analysis shows that the mass-loss rate of the progenitor has decreased constantly from = 4 × 10-4 to 4 × 10-5 M yr-1 (vw/10 km s-1) during the late stage of the evolution. Assuming a spherically symmetric expansion, the circumstellar matter density profile is found to be significantly flatter (ρcsm r-1.63) than expected for a constant mass-loss rate and constant wind velocity profile (r-2). The observed evolution reflects a decrease in the mass-loss rate, an increase in the wind speed, or a combination of both, indicating that the progenitor likely was making a transition from the red to the blue supergiant phase during the late stage of its evolution.
Analysis of the Photon Spectrum in Inclusive $B\to X_s\,γ$ Decays
Creators: name: Neubert, Matthias
Publisher: name: arXiv
Year: 1993
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Using a combination of the operator product and heavy quark expansions, we resum the leading nonperturbative contributions to the inclusive photon spectrum in $B\to X_s\,γ$ decays. The shape of the spectrum is determined by a universal structure function, which describes the distribution of the light-cone momentum of the $b$-quark inside the $B$-meson. The moments of this function are proportional to forward matrix elements of higher-dimension operators. As a by-product, we obtain the bound $λ_1<0$ for one of the parameters of the heavy quark effective theory. The integral over the $B\to X_s\,γ$ structure function is related to the shape function that governs the fall-off of the lepton spectrum close to the endpoint in $B\to X_u\,\ell\,\barν$ decays. A measurement of the photon spectrum in rare $B$-decays can therefore help to obtain a model-independent determination of $V_{ub}$.

description: The recently announced results on the 21-cm absorption spectrum by the EDGES experiment can place very stringent limits on dark matter annihilation cross-sections. We properly take into account the heating energy released from dark matter annihilation from the radiation epoch to the 21-cm observation redshifts in the radiative transfer to compute the evolution of the gas temperature. Our results show that the global 21-cm absorption profile is a powerful cosmological probe of the dark matter interactions. For dark matter annihilating into electron-positron pairs, the EDGES results give a more stringent upper limit than the PLANCK result on the annihilation cross section at the lower dark matter mass region.

description: We study a coupled dynamics of a network and a particle system. Particles of density $ρ$ diffuse freely along edges, each of which is rewired at a rate given by a decreasing function of particle flux. We find that the coupled dynamics leads to an instability toward the formation of hubs and that there is a dynamic phase transition at a threshold particle density $ρ_c$. In the low density phase, the network evolves into a star-shaped one with the maximum degree growing linearly in time. In the high density phase, the network exhibits a fat-tailed degree distribution and an interesting dynamic scaling behavior. We present an analytic theory explaining mechanism for the instability and a scaling theory for the dynamic scaling behavior.

description: The 331 model, an extension of the standard electroweak theory to $SU(3)_L\times U(1)_X$, naturally predicts three families of quarks and leptons via the requirement of anomaly cancellation. This is accomplished by making one of the quark families transform differently from the other two, thus leading to flavor changing neutral currents. Using experimental input on neutral meson mixing, we show that the third family must be the one that is singled out, at least up to small family mixing. We additionally describe a convenient way to parametrize the new mixing matrix that plays a role in the gauge interactions of the ordinary quarks with the new 331 quarks.

description: Beginning with a straightforward formulation of electromagnetic cloaking that reduces to a boundary value problem involving a single Maxwell first-order differential equation, explicit formulae for the relative permittivity-permeability dyadic and fields of spherical and circular cylindrical annular cloaks are derived in terms of general compressed radial coordinate functions. The general formulation is based on the requirements that the cloaking occurs for all possible incident fields and that the cloaks with frequency w > 0 have continuous tangential E and H fields across their outer surfaces, and zero normal D and B fields at their inner material surfaces. The tangential-field boundary conditions at the outer surface of the cloak ensure zero scattered fields, and the normal-field boundary conditions at the inner surface of the cloak are compatible with zero total fields inside the interior cavity of the cloak. For spherical cloaks, unlike cylindrical cloaks, these boundary conditions lead to all the tangential components of the E and H fields being continuously zero across their inner surfaces -- cylindrical cloaks having delta functions in polarization densities at their inner surfaces. For bodies with no interior free-space cavities, the formulation is used to derive nonscattering spherical and cylindrical concentrators that magnify the incident fields near their centers. For static fields (w = 0), the boundary value formulation is appropriately modified to obtain a permeability dyadic that will cloak magnetostatic fields. Causality conditions imply that, unlike magnetostatic cloaking, electrostatic cloaking as well as low-frequency cloaking for w > 0 is not realizable.

Missing Baryons and the Warm-Hot Intergalactic Medium

description: Stars and gas in galaxies, hot intracluster medium, and intergalactic photo-ionized gas make up at most half of the baryons that are expected to be present in the universe. The majority of baryons are still missing and are expected to be hidden in a web of warm-hot intergalactic medium. This matter was shock-heated during the collapse of density perturbations that led to the formation of the relaxed structures that we see today. Finding the missing baryons and thereby producing a complete inventory of possibly the only detectable component of the energy-mass budget of the universe is crucial to validate or invalidate our standard cosmological model.

description: We use high-resolution observations of the Sun in Ca II H 3968 A from the Solar Optical Telescope on Hinode to show that there are at least two types of spicules that dominate the structure of the magnetic solar chromosphere. Both types are tied to the relentless magnetoconvective driving in the photosphere, but have very different dynamic properties. ``Type-I'' spicules are driven by shock waves that form when global oscillations and convective flows leak into the upper atmosphere along magnetic field lines on 3-7 minute timescales. ``Type-II'' spicules are much more dynamic: they form rapidly (in ~10s), are very thin (<200km wide), have lifetimes of 10-150s (at any one height) and seem to be rapidly heated to (at least) transition region temperatures, sending material through the chromosphere at speeds of order 50-150 km/s. The properties of Type II spicules suggest a formation process that is a consequence of magnetic reconnection, typically in the vicinity of magnetic flux concentrations in plage and network. Both types of spicules are observed to carry Alfven waves with significant amplitudes of order 20 km/s.

Analysis of viscoelastic flow with a generalized memory and its exponential convergence to steady state

description: We investigate a viscoelastic flow model with a generalized memory, in which a weak-singular component is introduced in the exponential convolution kernel of classical viscoelastic flow equations that remains untreated in the literature. We prove the well-posedness and regularity of the solutions, based on which we prove the exponential convergence of the solutions to the steady state. The proposed model serves as an extension of classical viscoelastic flow equations by adding a dimension characterized by the power of the weak-singular kernel, and the derived results provide theoretical supports for designing numerical methods for both the considered equation and its steady state.

description: Xylella fastidiosa (Xf) is classified as a mesophilic bacterium particularly well adapted to areas with mild winters. The effects of temperature on Xf development have been addressed only for Xf subsp. fastidiosa strains. In this work, we have explored the effects of temperature on growth and biofilm formation in vitro for Xf strains representative of Xf subspecies prevalent in the European outbreaks. Growth, biofilm formation and cell viability of Xf strains from subsp. fastidiosa (7 strains), multiplex (18 strains), pauca (3 strains) and sandyi (2 strains) of different geographic and host origin have been determined in microplates with PD3 medium incubated at a constant temperature range of 6–32 °C at 4 °C intervals. Growth was determined daily by optical density at 600 nm, and biofilm was assessed at the end of the experiments by a crystal violet assay. Both parameters were modelled using a beta function to estimate the cardinal and optimal temperature values for each strain. Our results indicate that both growth and biofilm formation is determined by temperature and Xf strain. Overall, minimum vales for both parameters were observed at the extreme temperatures of 6 and 32 °C. However, the range with optimal values largely depends on the Xf strain. Although no distinct range was associated with subspecies, the widest temperature range for optimal growth was estimated for Xf subsp. multiplex strains at 20–32 °C. Optimal growth was estimated at 24–32 °C for Xf subsp. fastidiosa strains. No clear pattern was found for Xf subsp. pauca, with optimal values between 16 and 24 °C or 20 and 28 °C, depending on the strains. Similarly, for Xf subsp. sandyi, optimal growth occurred at 16–28 °C or 20–28 °C. With a few exceptions, similar response to temperature was observed for biofilm formation.These results would allow the development of region-specific epidemiological models to predict the risk associated with the establishment and spread of Xf strains in Europe.

Constraints on left-right symmetric models from the process $b \rightarrow s γ$

description: In left-right symmetric models, large contributions to the decay amplitude $b \rightarrow s+ γ$ can arise from the mixing of the $W_L$ and $W_R$ gauge bosons as well as from the charged Higgs boson. These amplitudes are enhanced by the factor $\mt/\mb$ compared to the contributions in the standard model. We use the recent CLEO results on the radiative $B$ decay to place constraints on the $W_L-W_R$ mixing angle $ζ$ and the mass of the charged Higgs boson $m_{H^\pm}$. Significant departures from the standard model predictions occur when $|ζ| > 0.003$ and/or when $m_{H^\pm} < $ a few TeV.

description: We study an agent-based model of evolution of wealth distribution in a macro-economic system. The evolution is driven by multiplicative stochastic fluctuations governed by the law of proportionate growth and interactions between agents. We are mainly interested in interactions increasing wealth inequality that is in a local implementation of the accumulated advantage principle. Such interactions destabilise the system. They are confronted in the model with a global regulatory mechanism which reduces wealth inequality. There are different scenarios emerging as a net effect of these two competing mechanisms. When the effect of the global regulation (economic interventionism) is too weak the system is unstable and it never reaches equilibrium. When the effect is sufficiently strong the system evolves towards a limiting stationary distribution with a Pareto tail. In between there is a critical phase. In this phase the system may evolve towards a steady state with a multimodal wealth distribution. The corresponding cumulative density function has a characteristic stairway pattern which reflects the effect of economic stratification. The stairs represent wealth levels of economic classes separated by wealth gaps. As we show, the pattern is typical for macro-economic systems with a limited economic freedom. One can find such a multimodal pattern in empirical data, for instance, in the highest percentile of wealth distribution for the population in urban areas of China.
