D4.2 Discussion paper on mechanisms that can ensure that EU policies are coherent with SDGs
Creators: name: Vlahos, George

name: Karytsas, Spyridon
Publisher: name: Zenodo
Year: 2023

description: This discussion paper examines the degree of policy coherence between the EU’s internal and external policies shaping agricultural trade and the alignment of EU agricultural trade policy and trade agreements in economic, social and environmental terms. Our analysis of all the agreements and political initiatives that make up the ‘core’ trade policy of the EU shows that a small number of trade agreements take into consideration in their provisions the environmental impact of agriculture, including issues such as the impact on soil and water quality, soil erosion and pollution by agricultural chemicals, the management of impacts through the use of antibiotics and decontaminants, conservation and sustainable use of biological diversity, and genetically modified organisms.

Three policy issues are examined from the multiplicity of policies enacted or initiated by the EU: organic farming certification, food safety regulations, and Green Deal and Biodiversity strategy targets. Three of the 15 MATS case studies (CS) have been selected to receive feedback on the region- or sector-specific impacts of the policies examined. A questionnaire was prepared and sent to project partners of the three CSs to get some feedback on the role the specific policy is playing in the CS and the sectors concerned. The first task of this exercise was to evaluate the specific policies within the framework of the specific CSs as far as their contribution to achieving the relevant Goals and Targets of the Sustainable Development Agenda 2030 were concerned. The Task leaders prepared a list of Goals and Targets and sent it to the CS partners for this purpose. Partners were asked to evaluate the policy according to the criteria provided by the International Council for Science (2017). Further, more policy-specific questions were posed to elicit the CS-relevant information necessary to analyse the results. Finally, policy proposals were provided by CS partners.

The conclusions of the analysis are divided into two parts: first, policy coherence and sustainability issues in EU trade-related policies, and second, policy proposals to increase coherence with sustainable trade; these policy proposals concern the EU organic farming certification scheme, the harmonised food safety regulations for EU imports, and agricultural extension and training.
Plastic deformation of gallium arsenide
Creators: name: Udevi-Aruevoru, Ikechukwu

Year: 2008

description: The present investigation was undertaken to determine the validity of Haasen's model of plastic deformation for GaAs over an extended range of temperatures and to observe the relation between the dislocation density in the deformed samples and the deformation variables. The experimental results show a discrepancy with the predictions of the model. This discrepancy and also the different values of the activation parameters reported in the literature was explained in terms of the contributions of temperature induced effects to the plastic strain rate . The dislocation densities in the deformed samples obtained by counting dislocation etch pits indicate that the density of dislocations in deformed GaAs is directly related to the applied stress, the plastic strain rate, the test temperature while being inversely related to the applied strain rate.
Review of Peter Szendy. 2008. Listen: A History of Our Ears. Translated by Charlotte Mandell. New York: Fordham University Press
Creators: name: Kane, Brian
Publisher: name: Current Musicology
Year: 2008

description: Peter Szendy’s first translation into English has appeared on the shelves not merely by chance. It arrives in the wake of two recent trends in the academic world: an intense interest in all things having to do with the history and culture of the senses, and the sudden accession of Jean-Luc Nancy as the Academy’s ‘philosophe du jour’. Of course, these two trends are not unrelated, for few philosophers have questioned the senses, especially the sense of touch, that Nancy has over the past two decades. However unlike the terse, Heideggerian-inflected prose of Nancy, Szendy’s work appears far more sober. At first glance, it is little more than a piecemeal work, centered around three topics: a sketchy history of musical copyright, a rehashing of the rise of the work concept, and another critique of “structural listening” in the name of the Benjamin distraction.

description: We investigate the ringdown waveform and reflectivity of a Lifshitz scalar field around a fixed Schwarzschild black hole. The radial wave equation is modified due to the Lorentz breaking terms, which leads to a diversity of ringdown waveforms. Also, it turns out that Lifshitz waves scattered by the Schwarzschild black hole exhibits superradiance. The Lorentz breaking terms lead to superluminal propagation and high-frequency modes can enter and leave the interior of the Killing horizon where negativity of energy is not prohibited. This allows the Lifshitz waves to carry out additional positive energy to infinity while leaving negative energy inside the Killing horizon, similar to the Penrose process in the ergosphere of a Kerr spacetime. Another interesting phenomenon is emergence of long-lived quasinormal modes, associated with roton-type dispersion relations. These effects drastically modify the greybody factor of a microscopic black hole, whose Hawking temperature is comparable with or higher than the Lifshitz energy scale.

description: We study 2D fronts propagating up a co-moving reaction rate gradient in finite number reaction-diffusion systems. We show that in a 2D rectangular channel, planar solutions to the deterministic mean-field equation are stable with respect to deviations from planarity. We argue that planar fronts in the corresponding stochastic system, on the other hand, are unstable if the channel width exceeds a critical value. Furthermore, the velocity of the stochastic fronts is shown to depend on the channel width in a simple and interesting way, in contrast to fronts in the deterministic MFE. Thus, fluctuations alter the behavior of these fronts in an essential way. These affects are shown to be partially captured by introducing a density cutoff in the reaction rate. Some of the predictions of the cutoff mean-field approach are shown to be in quantitative accord with the stochastic results.
Solid solubility of silver in the superconducting YBa₂Cu₃O compound
Creators: name: Zhang, Chongmin
Publisher: name: University of British Columbia
Year: 2008

description: The solubility of silver in the YBa₂Cu₃Ox compound has been studied. Ceramic YBa₂Cu₃Ox pellets with added silver ranging from 0 to 10 wt% were prepared and characterized by X-ray diffraction (XRD), optical microscopy, scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), wavelength dispersive X-ray spectroscopy (WDX), and secondary ion mass spectrometry (SIMS). The lattice parameters were precisely determined by a rigorous X-ray diffraction method and by using a USGS computer program which uses an iterative least square solution to calculate the lattice parameters and the standard deviations. The final precisions are±0.0005Å for lattice parameters a and b, and ±0.001Å for the lattice parameter c. Silver appears to be present within the YBa2Cu3Ox grains. More intragranular silver was found inside quenched samples than slowly cooled samples. In both cases the silver solubility increased with the nominal silver concentration, which reached a constant level as the nominal silver concentration exceeded 2.5 wt%. The maximum silver solubilities are 0.41 and 0.37 wt% for samples quenched from 950°C and slowly cooled to room temperature, respectively. The intragranular silver concentrations were found to be much lower than the nominal silver concentrations added to the system. . . . [more text]

description: This paper presents the preliminary results of the characterization of pattern evolution in the process of cosmic structure formation. We are applying on N-body cosmological simulations data the technique proposed by Rosa, Sharma & Valdivia (1999) and Ramos et al. (2000) to estimate the time behavior of asymmetries in the gradient field. The gradient pattern analysis is a well tested tool, used to build asymmetrical fragmentation parameters estimated over a gradient field of an image matrix able to quantify a complexity measure of nonlinear extended systems. In this investigation we work with the high resolution cosmological data simulated by the Virgo consortium, in different time steps, in order to obtain a diagnostic of the spatio-temporal disorder in the matter density field. We perform the calculations of the gradient vectors statistics, such as mean, variance, skewness, kurtosis, and correlations on the gradient field. Our main goal is to determine different dynamical regimes through the analysis of complex patterns arising from the evolutionary process of structure formation. The results show that the gradient pattern technique, specially the statistical analysis of second and third gradient moment, may represent a very useful tool to describe the matter clustering in the Universe.

Discrepancies with the older data are discussed. Comparison to different mass models is presented. Details of nuclear structure, shell and subshell closures are investigated by studying the two-neutron separation energy and the shell gap energy.

description: In a collaborative-filtering recommendation scenario, biases in the data will likely propagate in the learned recommendations. In this paper we focus on the so-called mainstream bias: the tendency of a recommender system to provide better recommendations to users who have a mainstream taste, as opposed to non-mainstream users. We propose NAECF, a conceptually simple but effective idea to address this bias. The idea consists of adding an autoencoder (AE) layer when learning user and item representations with text-based Convolutional Neural Networks. The AEs, one for the users and one for the items, serve as adversaries to the process of minimizing the rating prediction error when learning how to recommend. They enforce that the specific unique properties of all users and items are sufficiently well incorporated and preserved in the learned representations. These representations, extracted as the bottlenecks of the corresponding AEs, are expected to be less biased towards mainstream users, and to provide more balanced recommendation utility across all users. Our experimental results confirm these expectations, significantly improving the recommendations for non-mainstream users while maintaining the recommendation quality for mainstream users. Our results emphasize the importance of deploying extensive content-based features, such as online reviews, in order to better represent users and items to maximize the de-biasing effect.

description: We consider the scattering of $n$ classical particles interacting via pair potentials, under the assumption that each pair potential is "long-range", i.e. being of order ${\cal O}(r^{-α})$ for some $α>0$. We define and focus on the "free region", the set of states leading to well-defined and well-separated final states at infinity. As a first step, we prove the existence of an explicit, global surface of section for the free region. This surface of section is key to proving the smoothness of the map sending a point to its final state and to establishing a forward conjugacy between the $n$-body dynamics and free dynamics.

description: Materials where localized magnetic moments are coupled to itinerant electrons, the so-called Kondo lattice materials, provide a very rich backdrop for strong electron correlations. They are known to realize many exotic phenomena, including unconventional superconductivity, strange metals, and correlated topological phases of matter. Here, we report what appears to be electron fractionalization in insulating Kondo lattice material YbIr$_3$Si$_7$, with emergent neutral excitations that carry heat but not electric current and contribute to metal-like specific heat. We show that these neutral particles change their properties as the material undergoes a transformation between two antiferromagnetic phases in an applied magnetic field. In the low-field AF-I phase, we find that the low temperature linear specific heat coefficient $γ$ and the residual linear term in the thermal conductivity $κ/T(T\rightarrow 0)$ are finite, demonstrating itinerant gapless excitations. These results, along with a spectacular violation of the Wiedemann-Franz law, directly indicate that YbIr$_3$Si$_7$ is a charge insulator but a thermal metal. Nuclear magnetic resonance spectrum reveals a spin-flop transition to a high field AF-II phase. Near the transition field, $γ$ is significantly enhanced. Most surprisingly, inside the AF-II phase, $κ/T$ exhibits a sharp drop below $\sim300$ mK, indicating either opening of a tiny gap or a linearly vanishing density of states. This finding demonstrates a transition from a thermal metal into an insulator/semimetal driven by the spin-flop magnetic transition. These results suggest that spin degrees of freedom directly couple to the neutral fermions, whose emergent Fermi surface undergoes a field-driven instability at low temperatures.

description: We theoretically study a cavity filled with atoms, which provides the optical-mechanical interaction between the modified cavity photonic field and a movable mirror at one end. We show that the cavity field ``dresses'' these atoms, producing two types of polaritons, effectively enhancing the radiation pressure of the cavity field upon the end mirror, as well as establishing an additional squeezing mode of the end mirror. This squeezing produces an adiabatic entanglement, which is absent in usual vacuum cavities, between the oscillating mirror and the rest of the system. We analyze the entanglement and quantify it using the Loschmidt echo and fidelity.

description: The combination of data from multiple sensors, also known as sensor fusion or data fusion, is a key aspect in the design of autonomous robots. In particular, algorithms able to accommodate sensor fusion techniques enable increased accuracy, and are more resilient against the malfunction of individual sensors. The development of algorithms for autonomous navigation, mapping and localization have seen big advancements over the past two decades. Nonetheless, challenges remain in developing robust solutions for accurate localization in dense urban environments, where the so called last-mile delivery occurs. In these scenarios, local motion estimation is combined with the matching of real-time data with a detailed pre-built map. In this paper, we utilize data gathered with an autonomous delivery robot to compare different sensor fusion techniques and evaluate which are the algorithms providing the highest accuracy depending on the environment. The techniques we analyze and propose in this paper utilize 3D lidar data, inertial data, GNSS data and wheel encoder readings. We show how lidar scan matching combined with other sensor data can be used to increase the accuracy of the robot localization and, in consequence, its navigation. Moreover, we propose a strategy to reduce the impact on navigation performance when a change in the environment renders map data invalid or part of the available map is corrupted.

description: After years and years of debate, has music studies come to a consensus on how to relate culturalist and historicist claims about music to formal claims? Or are most analytical approaches still to external to musical experience? In Charlotte Mandell’s splendid translation of Jean-Luc Nancy’s brief but passionate À l’écoute, the French philosopher gives us a glimpse of a completely different philosophy of music. Uninterested in wresting out the dialectic between immaterial structure and the materiality of a self-evident cultural practice, Nancy’s notion of music in Listening (as Mandell has translated in À l’écoute) respects no proper distinction between subject (listeners, participants, composers, musicians, or otherwise) and object (say, a thing or phenomenon of organized sound). Nancy prefers to think of music as the becoming-sound of sense; this means his book is not so much a “philosophy of music” in the regular sense of the phrase as it is a philosophy of listening.

Speaking and Sighing: Bellini’s canto declamato and the Poetics of Restraint
Creators: name: Esse, Melina
Publisher: name: Current Musicology
Year: 2009

description: Vincenzo Bellini’s two successes of the late 1820’s- Il Pirata in 1827 and La straniera in 1829- had attracted a great deal of attention in the Italian press, and what drew the most comment was his novel approach to melody. Stripping away ornament to tie melody closely to the rhythms of the spoken word seemed a radical move to audiences who had been taking pleasure in Rossini’s florid and showy style for the last two decades. Despite the mixed response from Bellini’s contemporaries, modern scholars have tended to understand these melodic reforms in wholly positive terms. Ninteenth-century critics also tended to understand Beliini’s canto declamato as a renunciation of excess. Detactors and supporters alike labeled the new style “filosofico”, linking it to the burgeoning Romantic movement in the literary arts.

description: The evolution of large-scale density perturbations is studied in a stably stratified, two-dimensional flow governed by the Boussinesq equations. As is known, intially smooth density (or temperature) profiles develop into fronts in the very early stages of evolution. This results in a frontally dominated $k^{-1}$ potential energy spectrum. The fronts, initially characterized by a relatively simple geometry, spontaneously develop into severely distorted sheets that possess structure at very fine scales, and thus there is a transfer of energy from large to small scales. It is shown here that this process culminates in the establishment of a $k^{-5/3}$ kinetic energy spectrum, although its scaling extends over a shorter range as compared to the $k^{-1}$ scaling of the potential energy spectrum. The establishment of the kinetic energy scaling signals the onset of enstrophy decay which proceeds in a mildly modulated exponential manner and possesses a novel self-similarity. Specifically, the self-similarity is seen in the time invariant nature of the probability density function (\pdf{}) associated with the normalized vorticity field. Given the rapid decay of energy at this stage, the spectral scaling is transient and fades with the emergence of a smooth, large-scale, very slowly decaying, (almost) vertically sheared horizontal mode with most of its energy in the potential component -- i.e. the Pearson-Linden regime.

description: This article reports on the influence of laser irradiation onto the electrical conductance of gold nanocontacts established with the mechanically controllable breakjunction technique (MCB). We concentrate here on the study of reversible conductance changes which can be as high as 200%. We investigate the dependence on the initial conductance of the contacts, the wavelength, the intensity and position of the laser spot with respect to the sample. Under most conditions an enhancement of the conductance is observed. We discuss several physical mechanisms which might contribute to the observed effect including thermal expansion, rectification and photon-assisted transport. We conclude that thermal expansion is not the dominating one.

description: The quantum vacuum fluctuations of a neutral scalar field induced by background zero-range potentials concentrated on a flat hyperplane of co-dimension $1$ in $(d+1)$-dimensional Minkowski spacetime are investigated. Perfectly reflecting and semitransparent surfaces are both taken into account, making reference to the most general local, homogeneous and isotropic boundary conditions compatible with the unitarity of the quantum field theory. The renormalized vacuum polarization is computed for both zero and non-zero mass of the field, implementing a local version of the zeta regularization technique. The asymptotic behaviours of the vacuum polarization for small and large distances from the hyperplane are determined to leading order. It is shown that boundary divergences are soften in the specific case of a pure Dirac delta potential.

We find that the ground state is a charge density wave state with a long range order. The ground state is completely incompressible since all the excitations are gapful. The charge gap which is the same as the four-particle excitation gap is a non-monotonic function of U, while the spin gap and others increase with increasing |U| and have linear asymptotic behaviors.

description: Thermal-infrared measurements of asteroids are crucial for deriving the objects' sizes, albedos, and also the thermophysical properties of the surface material. Depending on the available data, a range of simple to complex thermal models are applied to achieve specific science goals. However, testing these models is often a difficult process and the uncertainties of the derived parameters are not easy to estimate. Here, we make an attempt to verify a widely accepted thermophysical model (TPM) against unique thermal infrared (IR), full-disk, and well-calibrated measurements of the Moon. The data were obtained by the High-resolution InfraRed Sounder (HIRS) instruments on board a fleet of Earth weather satellites that serendipitously scan over the Moon. We found 22 Moon intrusions, taken in 19 channels between 3.75 micron and 15.0 micron, and over a wide phase angle range from -73.1 deg to +73.8 deg. The similarity between these Moon data and typical asteroid spectral-IR energy distributions allows us to benchmark the TPM concepts and to point out problematic aspects. The TPM predictions match the HIRS measurements within 5% (10% at the shortest wavelengths below 5 micron when using the Moon's known properties (size, shape, spin, albedo, thermal inertia, roughness) in combination with a newly established wavelength-dependent hemispherical emissivity. In the 5-7.5 micron and in the 9.5 to 11 micron ranges, the global emissivity model deviates considerably from the known lunar sample spectra. Our findings will influence radiometric studies of near-Earth and main-belt asteroids in cases where only short-wavelength data (from e.g., NEOWISE, the warm Spitzer mission, or ground-based M-band measurements) are available. The new, full-disk IR Moon model will also be used for the calibration of IR instrumentation on interplanetary missions (e.g., for Hayabusa-2) and weather satellites.

description: Studies of music and childhood have a long, if irregular, history, but childhood nonetheless remains a marginal topic in musicology. In the last decade, a number of books, articles and dissertations have begun to argue that music and aesthetics are key elements in children’s social practices, in the articulation of childhood identity , and in adult frameworks for understanding their own and others’ childhoods, and that children and childhood deserve prominent attention from musicologists. In this environment, Musical Childhoods and the Cultures of Youth represents an important achievement, appearing at an opportune moment to consolidate this emerging literature and lay the foundations of a developing field of study.

Representation reduction and solution space contraction in quasi-exactly solvable systems
Creators: name: Alhaidari, A. D.
Publisher: name: arXiv
Year: 2006
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: In quasi-exactly solvable problems partial analytic solution (energy spectrum and associated wavefunctions) are obtained if some potential parameters are assigned specific values. We introduce a new class in which exact solutions are obtained at a given energy for a special set of values of the potential parameters. To obtain a larger solution space one varies the energy over a discrete set (the spectrum). A unified treatment that includes the standard as well as the new class of quasi-exactly solvable problems is presented and few examples (some of which are new) are given. The solution space is spanned by discrete square integrable basis functions in which the matrix representation of the Hamiltonian is tridiagonal. Imposing quasi-exact solvability constraints result in a complete reduction of the representation into the direct sum of a finite and infinite component. The finite is real and exactly solvable, whereas the infinite is complex and associated with zero norm states. Consequently, the whole physical space contracts to a finite dimensional subspace with normalizable states.

description: This presentation stems from a 2-hour workshop given at the Winter Institute in Digital Humanities at NYC Digital Humanities Week 2021 (February 8–12, 2021). The aim of this workshop was to familiarize novice Google Sheets users, particularly those with qualitative Humanities backgrounds, with various tools to organize and explore their data during the data collection process. Full presentation description: Google Sheets is a web-based spreadsheet program, equivalent in some ways to Microsoft Excel, with a wide array of features and uses. For people who would like to embark on a digital humanities project, it is one of many options for organizing data. This workshop is aimed at total beginners and will introduce a few ways to facilitate automatic data entry, organization, and visualization on Google Sheets. The skills presented in this workshop are suitable for anyone working with spreadsheets, and apply for any project in which there is repeated information (names, places, objects, dates). We will learn to sort and filter data, auto-populate cells, and organize sheets visually. The workshop is in three parts: first, an overview of Google Sheets and potential use cases (e.g., art exhibitions over time, books authored by a publishing house); second, a detailed explanation of some of Google Sheets’ features (Code Tables, Data Validation, Conditional Formatting, VLookup, Column Stats and Filters, and Pivot Tables); and third, a walk-through of these tools using a sample data set. Participants can follow along with the walk-through by using their own data or the sample set provided. Skill level: Total Beginner
 Prerequisites/requirements: Basic familiarity with Google Sheets or Excel. The course will be carried out using Google Sheets. You will be added to a shared sheet using the email address that you provide for the registration, so a Google account is required. Participants can also observe the process without using the Sheets and can use their own data set to practice the skills learned.

description: Frequency-angular distributions for THz emission in the range of 0.1 - 3 THz generated in a single-color laser filament plasma situated both under and without electrostatic field are for the first time experimentally studied. The angular distribution for various spectral components of this THz emission is demonstrated to differ significantly. The maximal propagation angles for these components grow up under the electric field, the angular distribution for the low-frequency THz emission depending significantly on the laser pulse energy in contrast to the case of no electric field. An increase in the laser pulse energy leads to a decrease of the propagation angles for low-frequency THz emission and to disappearance of the local minimum in the angular distribution on the propagation axis.
Electrochemical behaviour of gallium arsenide
Creators: name: Liu, Gordon Gang
Publisher: name: University of British Columbia
Year: 2010

description: Polarization behaviours of copper diffused p-type GaAs was studied in 1. 0M NaCl and 1. 0M NaNO₃ by means of pitting scan and linear sweep potentiodynamic polarization techniques. The thermodynamic potential-pH diagram of the GaAs-H₂O system was constructed. The observed electrode behaviours of GaAs were compared and correlated to the potential-pH diagram. Freely corroding potential, passivation behaviour and pitting potential were examined as a function of a number of factors. These included the effects of different annealing and polishing pretreatments, the bulk solution pH and polarization methods. The corrosion potential (Ecorr) , pitting potential (Epit) and passivation behaviour were affected by the different pretreatments which changed the surface condition of GaAs. For mechanically polished samples, pitting corrosion was found in pH 7.0 solution only. The Ecorr and Eplt were independent of NO₃⁻ and Cl⁻ at pH 7.0. Initial polarization behaviour of p-GaAs at pH 2.0 and 12.0 followed the Tafel Law for semiconductors quite well. There was a reasonable correlation between the experimental observations and the potential-pH diagram of GaAs-H₂O system. SEM images of polarized samples showed that pits formed in NaCl and NaNO₃ had a different shape, being more elongated in NaCl. However, the walls of all pits appeared to be composed of {111} planes. In general, the pit distribution appeared to be similar to the dislocation distribution. A model of pitting corrosion of GaAs was proposed based on strain induced breakdown of the oxide film, localized changes in solution chemistry and the structure of the compound semiconductor.

Generalized Gauge Field Approach To Lightlike Branes

description: We propose a general action describing the dynamics of lightlike (LL) p-branes in any odd (p+1) world-volume dimensions. Next, we consider self-consistent coupling of \textsl{LL}-membranes (p=2) to D=4 Einstein-Maxwell system plus a D=4 three-index antisymmetric tensor gauge field. The LL-brane serves as a material and charge source for gravity and electromagnetism and, furthermore, it produces a dynamical space-varying cosmological constant. We present static spherically-symmetric solutions where the space-time consists of two regions with different black-hole-type geometries and different values for dynamically generated cosmological constant, separated by the LL-brane which "straddles" their common event horizon.

Kundry and the Jewish Voice: Anti-antisemitism and Musical Transcendence in Wagner’s Parsifal
Creators: name: Binder, Benjamin
Publisher: name: Current Musicology
Year: 2009

description: Kundry, the only female character in Richard Wagner’s last opera, Parsifal (1882), is also the only character to make an overwhelming impression with the raw power and extreme versatility of her singing voice. Binder explores some pertinent aspects of Wagner’s anti-Semitic ideology in order to set up a close reading of what happens to Kundry’s voice in Acts II and III- how even beyond her last vocal utterance, Kundry’s “voice” remains, although its potency is subjugated and channeled into the work of transfigurative redemption whose blinding musical sublimity moves us at the same time that it requires complicity with its deep-seated anti-Semetic agenda. Finally, in an epilogue, Binder will suggest another view of Kundry’s voice, inspired by a different facet of Wagner’s thought, that may help with understanding more fully why antisemitism and transcendence are so inextricably and uncomfortably linked in Parsifal, both musically and dramaturgically: the voice of an animal.

A Variety of Nontopological Solitons in a Spontaneously Broken U(1) Gauge Theory -- Dust Balls, Shell Balls, and Potential Balls

description: We show, by numerical calculations, that there exist three-types of stationary and spherically symmetric nontopological soliton solutions (NTS-balls) with large sizes in the coupled system consisting of a complex matter scalar field, a U(1) gauge field, and a complex Higgs scalar field that causes spontaneously symmetry breaking. Under the assumption of symmetries, the coupled system reduces to a dynamical system with three degrees of freedoms governed by an effective action. The effective potential in the action has stationary points. The NTS-balls with large sizes are described by bounce solutions that start off an initial stationary point, and traverse to the final stationary point, vacuum stationary point. According to the choice of the initial stationary point, there appear three types of NTS-balls: dust balls, shell balls, and potential balls with respect to their internal structures.

Computing nonlinear force-free fields in spherical geometry

description: We describe a newly developed code for the extrapolation of nonlinear force-free coronal magnetic fields in spherical coordinates. The program uses measured vector magnetograms on the solar photosphere as input and solves the force-free equations in the solar corona. The method is based on an optimization principle and the heritage of the newly developed code is a corresponding method in Cartesian geometry. We test the newly developed code with the help of a semi-analytic solution and rate the quality of our reconstruction qualitatively by magnetic field line plots and quantitatively with a number of comparison metrics. We find that we can reconstruct the original test field with high accuracy. The method is fast if the computation is limited to low co-latitudes (say $30^\circ \leq θ\leq 150^\circ$), but becomes significantly slower if the polar regions are included.
