Finite-size-induced transitions to synchrony in oscillator ensembles with nonlinear global coupling

description: We report on finite-sized-induced transitions to synchrony in a population of phase oscillators coupled via a nonlinear mean field, which microscopically is equivalent to a hypernetwork organization of interactions. Using a self-consistent approach and direct numerical simulations, we argue that a transition to synchrony occurs only for finite-size ensembles, and disappears in the thermodynamic limit. For all considered setups, that include purely deterministic oscillators with or without heterogeneity in natural oscillatory frequencies, and an ensemble of noise-driven identical oscillators, we establish scaling relations describing the order parameter as a function of the coupling constant and the system size.

description: Emotional arousal increases activation and performance but may also lead to burnout in software development. We present the first version of a Software Engineering Arousal lexicon (SEA) that is specifically designed to address the problem of emotional arousal in the software developer ecosystem. SEA is built using a bootstrapping approach that combines word embedding model trained on issue-tracking data and manual scoring of items in the lexicon. We show that our lexicon is able to differentiate between issue priorities, which are a source of emotional activation and then act as a proxy for arousal. The best performance is obtained by combining SEA (428 words) with a previously created general purpose lexicon by Warriner et al. (13,915 words) and it achieves Cohen's d effect sizes up to 0.5.

description: Iᚑᚌᚆᚐᚋ (Ogham) stones are monoliths with the early medieval Primitive Irish Ogham script, placed on the island of Ireland and in the western part of Britain between the 4th and 9th centuries. They are an essential source for Archaic or Proto-Irish language and society. The letters of the Ogham alphabet consist of strokes written at different lengths and angles along (often natural) edges of the stones from the bottom left to the top and back down to the right. Names on the stones appear to be dedicated to a person. It remains unclear, however, whether the stones were grave markers, for example, or denoted land ownership. The stones are mostly no longer at the original site, which is, on the one hand, essential for cartographic recording (do you link the original site if known?) and, on the other hand, makes it more difficult to deduce their original function. Documentation on Ogham stones is available in many analogue sources and partly open online databases or repositories. However, as there is no common identification standard (e.g. stones, sites), these data cannot be analysed together; they need to be interoperable. The ogham.link project of the Research Squirrel Engineers Network creates a semantically modelled data basis as Linked Open Data (LOD) using community hubs such as Open Street Map and Wikidata. A Fellowship from Wikimedia Deutschland has already funded it in the Free Knowledge Fellow Programme as 'Irish ᚑᚌᚆᚐᚋ Stones in the Wikimedia Universe'. The data and geodata are extracted through a workflow, modelled and made available via various hubs. In the Fellow project, this was done primarily as native RDF data and as Quick Statements for integration into Wikidata. In Wikidata, sites can be linked to Irish townlands, for which there is a platform townlands.ie based on OSM data if these cannot be determined more precisely on site. Various archaeological items have been tagged in OpenStreetMap by "b-unicycling", including historic=ogham_stone. This makes Ogham data available in OSM with the tag ogham_stone and lends itself to linking the data mentioned in Wikidata, along with images on Wikimedia Commons and Flickr, to create an Ogham Knowledge Graph. This talk gives insights into the documentation, modelling and publication of selected Ogham stones from Ireland in OSM (user: b-unicycling, fthierygeo) and Wikidata (user: fthierygeo, Sophie_C._Schmidt). It shows how to create a Knowledge Graph with meta- and paradata and images. On top of that, the talks show how to integrate OSM data and Wikidata in QGIS using several Plugins, such as the "SPARQLing Unicon QGIS Plugin" or "QuickOSM" to perform further analysis. It also gives an overview of townland modelling and the publication of heritage sites using Web GIS systems and open geodata.

Current advanced computation calculators lack an efficient human-machine interface, with its unchanged traditional design traced back to the early 1960’s electro-mechanical commercialized solutions. The present article highlights how the perceived safety of “designing by tradition” can actually prevent evolution, and proposes - in a logical and argumentative way - a new layout based on the circular group approach, which derives from various already successful and working systems operating in society. Numerical comparison of the time spent in computing between the classical matrix calculator layout and the new circular group approach have shown that substantial time-saving can be achieved, in addition to the calculation acceleration effect imparted by aligning the highly organized calculator design with the intuitive nature of the mind of the user. Ultimately, the importance of such an advancement is appreciated when considering the compounding time-saving effect on the millions of users that will spend hours operating calculators in the years to come.

Dimensionally Induced Phase Transition of the Weakly Interacting Ultracold Bose Gas
Creators: name: Irsigler, Bernhard
name: Pelster, Axel
Publisher: name: arXiv
Year: 2016
Subjects: subject: Quantum Gases (cond-mat.quant-gas)
subject: FOS: Physical sciences

description: We investigate the dimensionally induced phase transition from the normal to the Bose-Einstein-condensed phase for a weakly interacting Bose gas in an optical lattice. To this end we make use of the Hartree-Fock-Bogoliubov-Popov theory, where we include numerically exact hopping energies and effective interaction strengths. At first we determine the critical chemical potential, where we find a much better agreement with recent experimental data than a pure Hartree-Fock treatment. This finding is in agreement with the dominant role of quantum fluctuations in lower dimensions, as they are explicitly included in our theory. Furthermore, we determine for the 1D-3D-transition the power-law exponent of the critical temperature for two different non-interacting Bose gas models yielding the same value of 1/2, which indicates that they belong to the same universality class. For the weakly interacting Bose gas we find for both models that this exponent is robust with respect to finite interaction strengths.
Influence of heat treatment excursion on critical current and residual resistivity ratio of ITER Nb3Sn strands

description: Heat treatment is critically important to the performance of Nb3Sn superconducting strands. For very large Nb3Sn magnet coils, such as the International Thermonuclear Experimental Reactor (ITER) Central Solenoid (CS) coils, heat treatment carries risk of temperature and time excursion, which may result in performance degradation. Therefore, it is prudent to study the effect of possible excursion on Nb3Sn performance. In this study, Nb3Sn strands used for ITER CS coils are heat treated at different temperatures for different times. Their critical current, residual resistance ratio and hysteresis losses are measured. It is found that in the range we studied, critical current and hysteresis losses do not change significantly. Residual resistance ratio, however, decreases with increasing heat treatment temperature and time. This is attributed to the diffusion of metallic elements from the plated Cr layer to the copper stabilizer. Based on a model of metallic elements diffusion, a numerical code is developed to predict residual resistance ratio as a function of heat treatment temperature and time.

description: We introduce two novel time-dependent figures of merit for both online and offline optimizations of advanced gravitational-wave (GW) detector network operations with respect to (i) detecting continuous signals from known source locations and (ii) detecting GWs of neutron star binary coalescences from known local galaxies, which thereby have the highest potential for electromagnetic counterpart detection. For each of these scientific goals, we characterize an $N$-detector network, and all its $(N-1)$-detector subnetworks, to identify subnetworks and individual detectors (key contributors) that contribute the most to achieving the scientific goal. Our results show that aLIGO-Hanford is expected to be the key contributor in 2017 to the goal of detecting GWs from the Crab pulsar within the network of LIGO and Virgo detectors. For the same time period and for the same network, both LIGO detectors are key contributors to the goal of detecting GWs from the Vela pulsar, as well as to detecting signals from 10 high interest pulsars. Key contributors to detecting continuous GWs from the Galactic Center can only be identified for finite time intervals within each sidereal day with either the 3-detector network of the LIGO and Virgo detectors in 2017, or the 4-detector network of the LIGO, Virgo, and KAGRA detectors in 2019-2020. Characterization of the LIGO-Virgo detectors with respect to goal (ii) identified the two LIGO detectors as key contributors. Additionally, for all analyses, we identify time periods within a day when lock losses or scheduled service operations could result with the least amount of signal-to-noise or transient detection probability loss for a detector network.

description: Thermal-diffusional pulsation behaviors in planar as well as outwardly and inwardly propagating white dwarf carbon flames are systematically studied. In the 1D numerical simulation, the asymptotic degenerate equation of state and simplified one-step reaction rates for nuclear reactions are used to study the flame propagation and pulsation in white dwarfs. The numerical critical Zel'dovich numbers of planar flames at different densities ($ρ=2$, 3 and 4$\times 10^7$~g/cm$^3$) and of spherical flames (with curvature $c=$-0.01, 0, 0.01 and 0.05) at a particular density ($ρ=2\times 10^7$~g/cm$^3$) are presented. Flame front pulsation in different environmental densities and temperatures are obtained to form the regime diagram of pulsation, showing that carbon flames pulsate in the typical density of $2\times10^7~{\rm g/cm^3}$ and temperature of $0.6\times 10^9~{\rm K}$. While being stable at higher temperatures, at relatively lower temperatures the amplitude of the flame pulsation becomes larger. In outwardly propagating spherical flames the pulsation instability is enhanced and flames are also easier to quench due to pulsation at small radius, while the inwardly propagating flames are more stable.

Ultrafast Energy Transfer with Competing Channels: Non-equilibrium Foerster and Modified Redfield Theories
Creators: name: Seibt, Joachim
name: Mancal, Tomas
Publisher: name: arXiv
Year: 2017
Subjects: subject: Chemical Physics (physics.chem-ph)
subject: FOS: Physical sciences

description: We derive equations of motion for the reduced density matrix of a molecular system which undergoes energy transfer dynamics competing with fast internal conversion channels. Environmental degrees of freedom of such a system have no time to relax to quasi-equilibrium in the electronic excited state of the donor molecule, and thus the conditions of validity of Foerster and Modified Redfield theories in their standard formulations do not apply. We derive non-equilibrium versions of the two well-known rate theories and apply them to the case of carotenoid-chlorophyll energy transfer. Although our reduced density matrix approach does not account for the formation of vibronic excitons, it still confirms the important role of the donor ground-state vibrational states in establishing the resonance energy transfer conditions. We show that it is essential to work with a theory valid in strong system-bath interaction regime to obtain correct dependence of the rates on donor-acceptor energy gap.

description: This study presents a Bayesian maximum \textit{a~posteriori} (MAP) framework for dynamical system identification from time-series data. This is shown to be equivalent to a generalized Tikhonov regularization, providing a rational justification for the choice of the residual and regularization terms, respectively, from the negative logarithms of the likelihood and prior distributions. In addition to the estimation of model coefficients, the Bayesian interpretation gives access to the full apparatus for Bayesian inference, including the ranking of models, the quantification of model uncertainties and the estimation of unknown (nuisance) hyperparameters. Two Bayesian algorithms, joint maximum \textit{a~posteriori} (JMAP) and variational Bayesian approximation (VBA), are compared to the {LASSO, ridge regression and SINDy algorithms for sparse} regression, by application to several dynamical systems with added {Gaussian or Laplace} noise. For multivariate Gaussian likelihood and prior distributions, the Bayesian formulation gives Gaussian posterior and evidence distributions, in which the numerator terms can be expressed in terms of the Mahalanobis distance or ``Gaussian norm'' $||\vec{y}-\hat{\vec{y}}||^2_{M^{-1}} = (\vec{y}-\hat{\vec{y}})^\top {M^{-1}} (\vec{y}-\hat{\vec{y}})$, where $\vec{y}$ is a vector variable, $\hat{\vec{y}}$ is its estimator and $M$ is the covariance matrix. The posterior Gaussian norm is shown to provide a robust metric for quantitative model selection {for the different systems and noise models examined.}

description: Magnetic skyrmions are topologically-protected spin textures with attractive properties suitable for high-density and low-power spintronic device applications. Much effort has been dedicated to understanding the dynamical behaviours of the magnetic skyrmions. However, experimental observation of the ultrafast dynamics of this chiral magnetic texture in real space, which is the hallmark of its quasiparticle nature, has so far remained elusive. Here, we report nanosecond-dynamics of a 100 nm-size magnetic skyrmion during a current pulse application, using a time-resolved pump-probe soft X-ray imaging technique. We demonstrate that distinct dynamic excitation states of magnetic skyrmions, triggered by current-induced spin-orbit torques, can be reliably tuned by changing the magnitude of spin-orbit torques. Our findings show that the dynamics of magnetic skyrmions can be controlled by the spin-orbit torque on the nanosecond time scale, which points to exciting opportunities for ultrafast and novel skyrmionic applications in the future.

This makes Ogham data available in OSM with the tag ogham_stone and lends itself to linking the data mentioned in Wikidata, along with images on Wikimedia Commons and Flickr, to create an Ogham Knowledge Graph. This talk gives insights into the documentation, modelling and publication of selected Ogham stones from Ireland in OSM (user: b-unicycling, fthierygeo) and Wikidata (user: fthierygeo, Sophie_C._Schmidt). It shows how to create a Knowledge Graph with meta- and paradata and images. On top of that, the talks show how to integrate OSM data and Wikidata in QGIS using several Plugins, such as the "SPARQLing Unicon QGIS Plugin" or "QuickOSM" to perform further analysis. It also gives an overview of townland modelling and the publication of heritage sites using Web GIS systems and open geodata. Version 2023/07/01: modified slide 19

description: A lattice computation of the leading-order hadronic contribution to the muon anomalous magnetic moment can potentially help reduce the error on the Standard Model prediction for this quantity, if sufficient control of all systematic errors affecting such a computation can be achieved. One of these systematic errors is that associated with the extrapolation to the physical pion mass from values on the lattice larger than the physical pion mass. We investigate this extrapolation assuming lattice pion masses in the range of 200 to 400MeV with the help of two-loop chiral perturbation theory, and find that such an extrapolation is unlikely to lead to control of this systematic error at the 1% level. This remains true even if various tricks to improve the reliability of the chiral extrapolation employed in the literature are taken into account. In addition, while chiral perturbation theory also predicts the dependence on the pion mass of the leading-order hadronic contribution to the muon anomalous magnetic moment as the chiral limit is approached, this prediction turns out to be of no practical use, because the physical pion mass is larger than the muon mass that sets the scale for the onset of this behavior.

description: We present a detailed study of the hydrogen density distribution in the local interstellar medium (ISM) using the X-ray absorption technique. Hydrogen column densities were precisely measured by fitting X-ray spectra from coronal sources observed during the initial {\it eROSITA} all-sky survey (eRASS1). Accurate distance measurements were obtained through cross-matching Galactic sources with the {\it Gaia} third data release (DR3). Despite the absence of a discernible correlation between column densities and distances or Galactic longitude, a robust correlation with Galactic latitude was identified. This suggests a decrease in ISM material density along the vertical direction away from the Galactic plane. To further investigate, we employed multiple density laws to fit the measured column densities, revealing constraints on height scale values ($8 < h_{z} < 30$~pc). Unfortunately, radial scales and central density remain unconstrained due to the scarcity of sources near the Galactic center. Subsequently, a 3D density map of the ISM was computed using a Gaussian processing approach, inferring hydrogen density distribution from hydrogen column densities. The results unveiled the presence of multiple beams and clouds of various sizes, indicative of small-scale structures. Large density regions were identified at approximately 100~pc, consistent with findings in dust reddening studies, potentially associated with the Galactic Perseus arm. Moreover, high-density regions were pinpointed in proximity to the Orion star-forming region and the Chamaeleon molecular complex, enriching our understanding of the intricate structure of the local interstellar medium.

description: Gamma-ray bursts (GRBs) are powerful probes of early stars and galaxies, during and potentially even before the era of reionization. Although the number of GRBs identified at z>6 remains small, they provide a unique window on typical star-forming galaxies at that time, and thus are complementary to deep field observations. We report the identification of the optical drop-out afterglow of Swift GRB 120923A in near-infrared Gemini-North imaging, and derive a redshift of z=7.84_{-0.12}^{+0.06} from VLT/X-shooter spectroscopy. At this redshift the peak 15-150 keV luminosity of the burst was 3.2x10^52 erg/s, and in fact the burst was close to the Swift/BAT detection threshold. The X-ray and near-infrared afterglow were also faint, and in this sense it was a rather typical long-duration GRB in terms of rest-frame luminosity. We present ground- and space-based follow-up observations spanning from X-ray to radio, and find that a standard external shock model with a constant-density circumburst environment with density, n~4x10^-2 cm^-3 gives a good fit to the data. The near-infrared light curve exhibits a sharp break at t~3.4 days in the observer frame, which if interpreted as being due to a jet corresponds to an opening angle of ~5 degrees. The beaming corrected gamma-ray energy is then E_gamma~2x10^50 erg, while the beaming-corrected kinetic energy is lower, E_K~10^49 erg, suggesting that GRB 120923A was a comparatively low kinetic energy event. We discuss the implications of this event for our understanding of the high-redshift population of GRBs and their identification.

description: How the solar corona is heated to high temperatures remains an unsolved mystery in solar physics. In the present study we analyse observations of 50 whole active-region loops taken with the Extreme-ultraviolet Imaging Spectrometer (EIS) on board the Hinode satellite. Eleven loops were classified as cool (<1 MK) and 39 as warm (1-2 MK) loops. We study their plasma parameters such as densities, temperatures, filling factors, non-thermal velocities and Doppler velocities. We combine spectroscopic analysis with linear force-free magnetic-field extrapolation to derive the three-dimensional structure and positioning of the loops, their lengths and heights as well as the magnetic field strength along the loops. We use density-sensitive line pairs from Fe XII, Fe XIII, Si X and Mg VII ions to obtain electron densities by taking special care of intensity background-subtraction. The emission-measure loci method is used to obtain the loop temperatures. We find that the loops are nearly isothermal along the line-of-sight. Their filling factors are between 8% and 89%. We also compare the observed parameters with the theoretical RTV scaling law. We find that most of the loops are in an overpressure state relative to the RTV predictions. In a followup study, we will report a heating model of a parallel-cascade-based mechanism and will compare the model parameters with the loop plasma and structural parameters derived here.

A Physics-Informed Indirect Method for Trajectory Optimization

description: This work presents a Physics-Informed Indirect Method (PIIM) that propagates the dynamics of both states and co-states backward in time for trajectory optimization problems. In the case of a Time-Optimal Soft Landing Problem (TOSLP), based on the initial co-state vector normalization technique, we show that the initial guess of the mass co-state and the numerical factor can be eliminated from the shooting procedure. As a result, the initial guess of the unknown co-states can be constrained to lie on a unit 3-D hypersphere. Then, using the PIIM allows one to exploit the physical significance of the optimal control law, which further narrows down the solution space to a unit 3-D octant sphere. Meanwhile, the analytical estimations of the fuel consumption and final time are provided. Additionally, a usually overlooked issue that results in an infeasible solution with a negative final time, is fixed by a simple remedy strategy. Consequently, the reduced solution space becomes sufficiently small to ensure fast, robust, and guaranteed convergence for the TOSLP. Then, we extend the PIIM to solve the Fuel-Optimal Soft Landing Problem (FOSLP) with a homotopy approach. The numerical simulations show that compared with the conventional indirect method with a success rate of 89.35%, it takes a shorter time for the proposed method to find the feasible solution to the FOSLP with a success rate of 100%.
