description: The stellar velocity distribution in the Solar Neighbourhood displays kinematic substructures, which are possibly signatures of the bar and spiral arms of the Milky Way and of previous accretion events. These kinematic substructures -- moving groups -- can be thought of as continuous manifolds in the 6D phase space, and the ridges in the $V_ϕ-R$ and arches in the $V_ϕ-V_R$ plane, discovered with the Gaia mission, as projections of these manifolds. We develop and apply a methodology to perform a blind search for substructure in the Gaia EDR3 6D data, and obtain a sampling of the manifolds. The method consists in the execution of the Wavelet Transform in small volumes of the Milky Way disc, and the grouping of these local solutions into global ones with a method based on the Breadth-first search algorithm from Graph Theory. We reveal the complex skeleton of the velocity distribution, sampling nine main moving groups in a large region of the disc ($6$ kpc, $60$ deg, and $2$ kpc in the radial, azimuthal, and vertical directions). In the radial direction, the groups deviate from lines of constant angular momentum that one would naively expect from first order effect of resonances. The azimuthal velocity of Acturus, Bobylev, and Hercules is non-axisymmetric. For Hercules, we measure an azimuthal gradient of $-0.50$ km/s/deg at $R=8$ kpc. We detect a vertical asymmetry in the azimuthal velocity for Coma Berenices, which is not expected in a resonance of the bar, supporting previous hypothesis of incomplete vertical phase-mixing. When we apply the same methodology to simulations of barred galaxies, we extract substructures corresponding to the Outer Linbdlad and the 1:1 Resonances and observe patterns consistent with the data. This data-driven characterization allows for a quantitative comparison with models, providing a key tool to comprehend the dynamics of the Milky Way. (Abridged)

description: We use a recently proposed luminosity distance measure for relatively nearby active galactic nuclei (AGNs) to test the predicted expansion of the Universe in the R_h=ct and LCDM cosmologies. This comparative study is particularly relevant to the question of whether or not the Universe underwent a transition from decelerated to accelerated expansion, which is believed to have occurred---on the basis of Type Ia SN studies---within the redshift range (0 < z < 1.3) that will eventually be sampled by these objects. We find that the AGN Hubble Diagram constructed from currently available sources does not support the existence of such a transition. While the scatter in the AGN data is still too large for any firm conclusions to be drawn, the results reported here nonetheless somewhat strengthen similar results of comparative analyses using other types of source. We show that the Akaike, Kullback, and Bayes Information Criteria all consistently yield a likelihood of ~84-96% that R_h=ct is closer to the "true" cosmology than LCDM is, though neither model adequately accounts for the data, suggesting an unnaccounted-for source of scatter.

description: Sentiment analysis has always been an important driver of political decisions and campaigns across all fields. Novel technologies allow automatizing analysis of sentiments on a big scale and hence provide allegedly more accurate outcomes. With user numbers in the billions and their increasingly important role in societal discussions, social media platforms become a glaring data source for these types of analysis. Due to its public availability, the relative ease of access and the sheer amount of available data, the Twitter API has become a particularly important source to researchers and data analysts alike. Despite the evident value of these data sources, the analysis of such data comes with legal, ethical and societal risks that should be taken into consideration when analysing data from Twitter. This paper describes these risks along the technical processing pipeline and proposes related mitigation measures.

description: Abstract
Background: Systemic lupus erythematosus (SLE) is an episodic, chronic, multisystem, autoimmune disease characterized by a widespread inflammation of blood vessels and connective tissues. There is no cure for lupus, but medical interventions and lifestyle modifications can help control it. The seriousness of SLE can range from mild to life-threatening. Patients with SLE who get proper medical care and education can significantly lower disease activity and improve quality of life. Aim of the study: The aim is to evaluate the effect of self-care instructional guide on disease activity among patients with SLE. Design: Non-Equivalent pretest-posttest time series control group design was used in the study. Setting: The study was conducted at the rheumatology and rehabilitation department in one of Cairo University affiliated hospitals. Sample: A convenient sample of 120 male and female adult conscious patients with SLE who fulfilled the eligibility criteria was recruited. Tools: socio-demographic and medical data questionnaire; the adopted systemic lupus erythematosus disease activity index (SLEDAI) and lupus patient's self-care knowledge assessment test were used to collect data. Results: 45.0% of the study group and 46.7% of the control group are within age range between 20 < 30 years, 86.7% of the study group and 91.7 % of the control group were females. As for disease activity index scores; there was a significant statistical difference in SLEDAI between the study and control groups after implementing nursing instructional guide (x2 = 17.0  P = (0.001), also, there were highly statistically significant differences in self-care knowledge scores between the study and control groups at 3rd day and  3rd month after implementing nursing instructional guide (x2 = 91.7  P = 0.0001), (x2= 91.7  P = 0.0001) respectively. Finally, there was a statistically significant negative relation between disease activity index and self-care knowledge (r = -0.12  p = 0.17). Conclusion: The self-care instructional guide had a significant effect on the improvement of patients with SLE self-care knowledge and lowering the disease activity state. Recommendation: regular implementation of instructional guidelines programs for patients with SLE to increase their knowledge and improve their quality of life.
A holographic bottom-up description of light nuclide spectroscopy and stability

description: This work explores a holographic proposal to describe light nuclide spectroscopy by considering extensions to the well-known bottom-up AdS/QCD proposals, the hardwall and softwall models. We also propose an alternative description inspired by the Woods-Saxon potential. We find the static dilaton associated with this potential in this Wood-Saxon-like model. We compute the nuclide spectra finding that, despite their pure AdS/QCD origin, hardwall and softwall, as monoparametric models, have good accuracy and precision since the RMS error is near 11 $\%$ and 4 $\%$ respectively. In the case of the Wood-Saxon model, the RMS was around 1 $\%$. We also discuss configurational entropy as a tool to categorize which model is suitable to describe nuclides in terms of stability. We found that configurational entropy resembles a stability line, independent from nuclear spin, for symmetric light nuclides when considering softwall and Wood-Saxon-like models. For the hardwall case, configurational entropy, despite increasing with the constituent number, depends on the nuclear spin. Thus, the Woods-Saxon-like model emerges as the best choice to describe light nuclide spectroscopy in the bottom-up scenario.

Laser-induced crystallization of copper oxide thin films: A comparison made between Gaussian and chevron-beam profiles provides a clue for the failure of Gaussian-beam profile

description: The use of laser with a Gaussian-beam profile is frequently adopted in attempts of crystallizing non-single-crystal thin films; however, it merely results in the formation of poly-crystal thin films. In this paper, selective area crystallization of non-single-crystal copper(II) oxide (CuO) is described. The crystallization is induced by laser, laser-induced crystallization, with a beam profile in the shape of chevron. The crystallization is verified by the exhibition of a transition from a non-single-crystal phase consisting of small 100 nm x 100 nm grains of CuO to a single-crystal phase of copper(I) oxide (Cu2O). The transition is identified by electron back scattering diffraction and Raman spectroscopy, which clearly suggests that a single-crystal domain of Cu2O with size as large as 5 μm x 1 mm develops. Provided these experimental findings, a theoretical assessment based on a cellular automaton model, with the behaviors of localized recrystallization and stochastic nucleation, is developed. The theoretical assessment can qualitatively describe the laser beam geometry-dependence of vital observable features (e.g., size and gross geometry of grains) in the laser-induced crystallization. The theoretical assessment predicts that differences in resulting crystallinity, either single-crystal or poly-crystal, primarily depend on a geometrical profile with which melting of non-single-crystal regions takes place along the laser scan direction; concave-trailing profiles yield larger grains which lead to single-crystal while convex-trailing profiles results in smaller grains which lead to poly-crystal, casting light on the fundamental question Why does a chevron-beam profile succeed in producing single-crystal while a Gaussian-beam profile fails?

description: Psychological research often involves the collection and processing of personal data from human research participants. The European General Data Protection Regulation (GDPR) applies, as a rule, to psychological research conducted on personal data in the European Economic Area (EEA)—and even, in certain cases, to psychological research conducted on personal data outside the EEA. The GDPR elaborates requirements concerning the forms of information that should be communicated to research participants whenever personal data are collected directly from them. There is a general norm that informed consent should be obtained before psychological research involving the collection of personal data directly from research participants is conducted. The information required to be provided under the GDPR is normally communicated in the context of an informed consent procedure. There is reason to believe, however, that the information required by the GDPR may not always be provided. Our aim in this tutorial is thus to provide general practical guidance to psychological researchers allowing them to understand the forms of information that must be provided to research participants under the GDPR in informed consent procedures.

description: A well-established numerical approach to solve the Navier--Stokes equations for incompressible fluids is Chorin's projection method, whereby the fluid velocity is explicitly updated, and then an elliptic problem for the pressure is solved, which is used to orthogonally project the velocity field to maintain the incompressibility constraint. In this paper, we develop a mathematical correspondence between Newtonian fluids in the incompressible limit and hypo-elastoplastic solids in the slow, quasi-static limit. Using this correspondence, we formulate a new fixed-grid, Eulerian numerical method for simulating quasi-static hypo-elastoplastic solids, whereby the stress is explicitly updated, and then an elliptic problem for the velocity is solved, which is used to orthogonally project the stress to maintain the quasi-staticity constraint. We develop a finite-difference implementation of the method and apply it to an elasto-viscoplastic model of a bulk metallic glass based on the shear transformation zone theory. We show that in a two-dimensional plane strain simple shear simulation, the method is in quantitative agreement with an explicit method. Like the fluid projection method, it is efficient and numerically robust, making it practical for a wide variety of applications. We also demonstrate that the method can be extended to simulate objects with evolving boundaries. We highlight a number of correspondences between incompressible fluid mechanics and quasi-static elastoplasticity, creating possibilities for translating other numerical methods between the two classes of physical problems.

description: We solve robot trajectory planning problems at industry-relevant scales. Our end-to-end solution integrates highly versatile random-key algorithms with model stacking and ensemble techniques, as well as path relinking for solution refinement. The core optimization module consists of a biased random-key genetic algorithm. Through a distinct separation of problem-independent and problem-dependent modules, we achieve an efficient problem representation, with a native encoding of constraints. We show that generalizations to alternative algorithmic paradigms such as simulated annealing are straightforward. We provide numerical benchmark results for industry-scale data sets. Our approach is found to consistently outperform greedy baseline results. To assess the capabilities of today's quantum hardware, we complement the classical approach with results obtained on quantum annealing hardware, using qbsolv on Amazon Braket. Finally, we show how the latter can be integrated into our larger pipeline, providing a quantum-ready hybrid solution to the problem.

description: We revisit astrophysical constraints on models with an ultra-light gravitino, in particular extending the analysis to more general models and the case of R-parity breaking. These constraints allow to restrict the value of the gravitino mass depending on the masses of scalar moduli. We perform both a frequentist and bayesian analysis and we find comparable results, even if the bayesian analysis is in part affected by volume effects. Only a small window of gravitino masses can be excluded by the SN constraints in a model-independent way, while limits obtained with a definite assumption on the scalar masses result more stringent.

description: Our aim in this paper is to present sufficient conditions for error bounds in terms of Frechet and limiting Frechet subdifferentials outside of Asplund spaces. This allows us to develop sufficient conditions in terms of the approximate subdifferential for systems of the form (푥, 푦) ∈ 퐶 × 퐷, 푔(푥, 푦, 푢) = 0, where 푔 takes values in an infinite dimensional space and 푢 plays the role of a parameter. This symmetric structure offers us the choice to impose condtions either on 퐶 or 퐷. We use these results to prove nonemptyness and weak-star compactness of Fritz-John and Karuch-Kuhn-Tucker multiplier sets, to establish Lipschitz continuity of the value function and to compute its subdifferential and finally to obtain results on local controllability in control problems of nonconvex unbounded differential inclusions.

description: In this paper, we develop a fully discrete entropy preserving ADER-Discontinuous Galerkin (ADER-DG) method. To obtain this desired result, we equip the space part of the method with entropy correction terms that balance the entropy production in space, inspired by the work of Abgrall. Whereas for the time-discretization we apply the relaxation approach introduced by Ketcheson that allows to modify the timestep to preserve the entropy to machine precision. Up to our knowledge, it is the first time that a provable fully discrete entropy preserving ADER-DG scheme is constructed. We verify our theoretical results with various numerical simulations.

description: Shelley's biographers have usually made little attempt to give a connected interpretation of the facts they exhibit; and other writers on Shelley have, for the most part, either restricted themselves to the minute examination of particular problems or else pronounced broad judgments without setting forth in detail the data on which those judgments are based. A new study was needed, it seemed to me, uniting with a connected interpretation such biographical and other data as may be necessary to support it. The present work is intended in part to supply that need. My primary aim has been to present a consecutive account of Shelley's development, as a thinker, a poet, and a responsible member of society, from the attitude of revolt, through conflict and suffering, to the attitude of compromise in his relations with the world and with his own soul. In addition, I have sought to correlate more completely than has been done before the several interests that occupied his thought -- politics, religion, benevolence, poetry, love -- and to portray him, not merely as a dreamer and a romantic poet of idealism, but as an earnest and perplexed citizen of the actual world, struggling to adjust himself to his environment, to secure his own happiness, and to achieve success in the work that he conceived to be his particular contribution to human welfare. My work has been facilitated by the recent publication of the volumes of the new Julian Edition of Shelley's Works which contain the letters, some of which had not before been published. I have found Dowden's Life of Shelley indispensable as a biographical guide. Other biographical works, those written by Shelley's friends and companions above all, I have, of course, found very valuable. For the text of the poetry I have used Forman's edition; for the prose writings, Forman's edition not being available, I have had recourse to the recent reprint of Shepherd's edition. I have read substantially all the important criticism relating to Shelley, and have taken account of it wherever it bears upon my own opinions, making due acknowledgment in such cases

description: This paper proves existence and stability results of solitary-wave solutions to coupled nonlinear Schrödinger equations with power-type nonlinearities arising in several models of modern physics. The existence of solitary waves is obtained by solving a variational problem subject to two independent constraints and using the concentration-compactness method. The set of minimizers is shown to be stable and further information about the structures of this set are given. The paper extends the results previously obtained by Cipolatti and Zumpichiatti, Nguyen and Wang, and Ohta.

description: Using the gauge/gravity duality, we calculate the electromagnetic contributions to hadron masses, where mass generates dynamically by strong QCD interactions. Based on the Sakai-Sugimoto model of holographic QCD we find that the electromagnetic mass of proton is $0.48~{\rm MeV}$ larger than that of neutron, which is in agreement with recent lattice results. Similarly for pions we obtain $m_{π^{\pm}}-m_{π^0}=1.8~{\rm MeV}$, roughly half of the experimental value. The electromagnetic mass of pions is found to be independent of $N_c$ and 't Hooft coupling and its scale is set only by the Kaluza-Klein scale of the model, $M_{\rm KK}=949~{\rm MeV}$.

description: Liquid water is one of the most studied substances, yet many of its properties are difficult to rationalize. The uniqueness of water is rooted in the dynamic network of hydrogen-bonded molecules with relaxation time constants of about one picosecond. Terahertz fields oscillate on a picosecond timescale and are inherently suited to study water. Recent advances in non-linear terahertz spectroscopy have revealed large signals from water, which have been interpreted with different, sometimes competing, theoretical models. Here we show that the non-linear transmission of liquid water at ~1 THz is equal at 21 °C and 4 °C, thus suggesting that the most appropriate microscopic models should depend weakly on temperature. Among the different mechanisms proposed to date, the resonant reorientation of hydrogen-bonded water molecules might be the most appropriate to describe all of the currently available experimental results.

Among the 241 recovered clusters, we identify more than 50 known associations, 32 new candidate stellar streams aged 100 Myr-3 Gyr, 9 extensions of known Theia groups uncovered by Kounkel & Covey (2019), and 8 newly recognized coronae around nearby open clusters. Three confirmed exoplanet-hosting stars and three more TESS transiting exoplanet candidates are part of the new groups discovered here, including TOI-1807 and TOI-2076 from Hedges et al. (2021) that were suspected to belong to a yet unidentified moving group. The new groups presented here were not previously recognized because of their older ages, low spatial density, and projection effects that spread out the tangential velocities of their nearby co-moving members. Several newly identified structures reach distances within 60 pc of the Sun, providing new grounds for the identification of isolated planetary-mass objects. The nearest member of the newly recognized corona of Volans-Carina is V419 Hya, a known young debris disk star at a distance of 22 pc. This study outlines the importance of further characterization of young associations in the immediate Solar neighborhood, which will provide new laboratories for the precise age calibration of nearby stars, exoplanets and substellar objects.

description: We show that charge fluctuation processes are crucial for the nonlinear heat conductance through an interacting nanostructure, even far from a resonance. We illustrate this for an Anderson quantum dot accounting for the first two leading orders of the tunneling in a master equation. The often made assumption that off-resonant transport proceeds entirely by virtual occupation of charge states, underlying exchange-scattering models, can fail dramatically for heat transport. The identified energy-transport resonances in the Coulomb blockade regime provide new qualitative information about relaxation processes, for instance by strong negative differential heat conductance relative to the heat current. These can go unnoticed in the charge current, making nonlinear heat-transport spectroscopy with energy-level control a promising experimental tool.

description: Human-elephant conflict (HEC) is a global conservation issue that undermines the conservation of an endangered species. HEC and the factors influencing crop-raiding behaviour were studied in the tropical forests of south India from Nov 2006 to Mar 2008. Crop depredation, protection methods, and land use changes were studied at Mudumalai Tiger Reserve (TR). A total of 297 incidents of crop damage were recorded, with peaks in the raiding during the monsoon season. Spatial analysis of HEC showed peripheral farms are more vulnerable (1.51%) than village centers (0.18%). Temporally, cropping patterns have changed from food crops to commercial crops. The elephant-damaged area was positively correlated with the effective perimeter (perimeter with crops), total cultivated area, and area of degradation around the village. Logistic regression of crop raiding incidence with independent predictors showed that the incidence of raiding was 95% greater in moist deciduous forests than in thorny forests. Palatable crops were likely to be raided more frequently (391 times). Crops with protection methods were 22 times less likely to be targets of raids. In the areas adjacent to the Mudumalai TR, crop species, improvements in protection, and land use change reduced the HEC. Relocating villages from the core reserve and existing corridors in the eastern region is essential for conserving elephants in the Nilgiris, Western Ghats landscape.

description: We measure the local correlation between radio emission and Compton-$y$ signal across two galaxy clusters, Abell~399 and Abell~401, using maps from the Low-Frequency Array (LOFAR) and the Atacama Cosmology Telescope (ACT) + \Planck. These datasets allow us to make the first measurement of this kind at $\sim$arcminute resolution. We find that the radio brightness scales as $F_{\mathrm{radio}} \propto y^{1.5}$ for Abell~401 and $F_{\mathrm{radio}} \propto y^{2.8}$ for Abell~399. Furthermore, using \XMM data, we derive a sublinear correlation between radio and X-ray brightness for both the clusters ($F_{\mathrm{radio}} \propto F_{\rm X}^{0.7}$). Finally, we correlate the Compton-$y$ and X-ray data, finding that an isothermal model is consistent with the cluster profiles, $y \propto F_{\rm X}^{0.5}$. By adopting an isothermal--$β$ model, we are able, for the first time, to jointly use radio, X-ray, and Compton-$y$ data to estimate the scaling index for the magnetic field profile, $B(r) \propto n_{\mathrm{e}}(r)^η$ in the injection and re-acceleration scenarios. Applying this model, we find that the combined radio and Compton-$y$ signal exhibits a significantly tighter correlation with the X-ray across the clusters than when the datasets are independently correlated. We find $η\sim 0.6{-}0.8$. These results are consistent with the upper limit we derive for the scaling index of the magnetic field using rotation measure values for two radio galaxies in Abell~401. We also measure the radio, Compton-$y$, and X-ray correlations in the filament between the clusters but conclude that deeper data are required for a convincing determination of the correlations in the filament.

description: We identify two ultra-cool ($T_\mathrm{eff} < 4000$ K) metal-polluted (DZ) white dwarfs WDJ2147$-$4035 and WDJ1922$+$0233 as the coolest and second coolest DZ stars known to date with $T_\mathrm{eff} \approx 3050$ K and $T_\mathrm{eff} \approx 3340$ K, respectively. Strong atmospheric collision-induced absorption (CIA) causes the suppression of red optical and infra-red flux in WDJ1922$+$0233, resulting in an unusually blue colour given its low temperature. WDJ2147$-$4035 has moderate infra-red CIA yet has the reddest optical colours known for a DZ white dwarf. Microphysics improvements to the non-ideal effects and CIA opacities in our model atmosphere code yields reasonable solutions to observations of these ultra-cool stars. WDJ2147$-$4035 has a cooling age of over 10 Gyr which is the largest known for a DZ white dwarf, whereas WDJ1922$+$0233 is slightly younger with a cooling age of 9 Gyr. Galactic kinematics calculations from precise Gaia EDR3 astrometry reveal these ultra-cool DZ stars as likely members of the Galactic disc thus they could be pivotal objects in future studies constraining an upper age limit for the disc of the Milky Way. We present intermediate-resolution spectroscopy for both objects, which provides the first spectroscopic observations of WDJ2147$-$4035. Detections of sodium and potassium are made in both white dwarfs, in addition to calcium in WDJ1922$+$0233 and lithium in WDJ2147$-$4035. We identify the magnetic nature of WDJ2147$-$4035 from Zeeman splitting in the lithium line and also make a tentative detection of carbon, so we classify this star as DZQH. WDJ1922$+$0233 likely accreted planetary crust debris, while the debris composition that polluted WDJ2147$-$4035 remains unconstrained.

When quantum corrections alter the predictions of classical field theory for scalar field dark matter

description: We investigate the timescale on which quantum corrections alter the predictions of classical field theory for scalar field dark matter. This is accomplished by including second order terms in the evolution proportional to the covariance of the field operators. When this covariance is no longer small compared to the mean field value, we say that the system has reached the ``quantum breaktime" and the predictions of classical field theory will begin to differ from those of the full quantum theory. While holding the classical field theory evolution fixed, we determine the change of the quantum breaktime as total occupation number is increased. This provides a novel numerical estimation of the breaktime based at high occupations $n_{tot}$ and mode number $N=256$. We study the collapse of a sinusoidal overdensity in a single spatial dimension. We find that the breaktime scales as $\log(n_{tot})$ prior to shell crossing and then then as a powerlaw following the collapse. If we assume that the collapsing phase is representative of halos undergoing nonlinear growth, this implies that the quantum breaktime of typical systems may be as large as $\sim 30$ of dynamical times even at occupations of $n_{tot}\sim 10^{100}$.

description: Die hier beschriebene Feldstudie untersucht die Wirkung didaktischer Prinzipien des Gameplays im Rahmen einer Blended Learning-Veranstaltung auf deren Beurteilung. Mittels Fragebogen wird der Zusammenhang zwischen der Bewertung der Lehrveranstaltung und Merkmalen der Studierenden (Vorwissen, aktuelle Motivation, epistemologische Überzeugungen, Hilfenutzungseinstellungen, Zielorientierung und Technologieakzeptanz) erfasst. Teilnehmende waren 34 Lehramtsstudierende, die vielfältige, in einem Moodle-Kurs implementierte, multimediale Lerninhalte bearbeiteten. Ergebnisse zeigen, dass das Veranstaltungsformat insbesondere bei Studierenden mit den epistemologischen Überzeugungen, dass Wissen sozial konstruiert und Lernen erlernbar ist, sowie bei hoher Technologieakzeptanz und hoher aktueller Motivation positiv evaluiert wird. Epistemologische Überzeugungen wirken unmittelbar und mittelbar über die Technologieakzeptanz und die aktuelle Motivation auf die Bewertung der Veranstaltung.
