description: We analyze the structure and evolution of ribbons from the M7.3 SOL2014-04-18T13 flare using ultraviolet (UV) images from IRIS and SDO/AIA, magnetic data from SDO/HMI, hard X-ray (HXR) images from RHESSI, and light curves from Fermi/GBM, in order to infer properties of coronal magnetic reconnection. As the event progresses, two flare ribbons spread away from the magnetic polarity inversion line. The width of the newly brightened front along the extension of the ribbon is highly intermittent in both space and time, presumably reflecting non-uniformities in the structure and/or dynamics of the flare current sheet. Furthermore, the ribbon width grows most rapidly in regions exhibiting concentrated non-thermal HXR emission, with sharp increases slightly preceding the HXR bursts. The light curve of the ultraviolet emission matches the HXR light curve at photon energies above 25 keV. In other regions the ribbon-width evolution and light curves do not temporally correlate with the HXR emission. This indicates that the production of non-thermal electrons is highly non-uniform within the flare current sheet. Our results suggest a strong connection between the production of non-thermal electrons and the locally enhanced perpendicular extent of flare ribbon fronts, which in turn reflects inhomogeneous structure and/or reconnection dynamics of the current sheet. Despite this variability, the ribbon fronts remain nearly continuous, quasi-one-dimensional features. Thus, although the reconnecting coronal current sheets are highly structured, they remain quasi-two-dimensional and the magnetic energy release occurs systematically, rather than stochastically, through the volume of reconnecting magnetic flux.

description: Public interest-oriented state control of research into climate engineering techniques - the Model London Protocol: Climate Engineering, including Carbon Dioxide Removal- and/or Solar Radiation Management-techniques, increasingly gets again into the public discussion on effective climate change policies. As most of these techniques are still in infancy, the question needs to be answered whether and how research and development should be controlled and governed by states. In this context, public funding may play an important role next to regulatory approaches.

description: As main-sequence stars with C$>$O, dwarf carbon (dC) stars are never born alone but inherit carbon-enriched material from a former asymptotic giant branch (AGB) companion. In contrast to M dwarfs in post-mass transfer binaries, C$_2$ and/or CN molecular bands allow dCs to be identified with modest-resolution optical spectroscopy, even after the AGB remnant has cooled beyond detectability. Accretion of substantial material from the AGB stars should spin up the dCs, potentially causing a rejuvenation of activity detectable in X-rays. Indeed, a few dozen dCs have recently been found to have photometric variability with periods under a day. However, most of those are likely post-common-envelope binaries (PCEBs), spin-orbit locked by tidal forces, rather than solely spun-up by accretion. Here, we study the X-ray properties of a sample of the five nearest known dCs with $Chandra$. Two are detected in X-rays, the only two for which we also detected short-period photometric variability. We suggest that the coronal activity detected so far in dCs is attributable to rapid rotation due to tidal locking in short binary orbits after a common-envelope phase, late in the thermally pulsing (TP) phase of the former C-AGB primary (TP-AGB).

description: We present a comparison of the nitrogen-to-oxygen ratio (N/O) in 37 high-redshift galaxies at $z\sim$2 taken from the KMOS Lensed Emission Lines and VElocity Review (KLEVER) Survey with a comparison sample of local galaxies, taken from the Sloan Digital Sky Survey (SDSS). The KLEVER sample shows only a mild enrichment in N/O of $+$0.1 dex when compared to local galaxies at a given gas-phase metallicity (O/H), but shows a depletion in N/O of $-$0.36 dex when compared at a fixed stellar mass (M$_*$). We find a strong anti-correlation in local galaxies between N/O and SFR in the M$_*$-N/O plane, similar to the anti-correlation between O/H and SFR found in the mass-metallicity relation (MZR). We use this anti-correlation to construct a fundamental nitrogen relation (FNR), analogous to the fundamental metallicity relation (FMR). We find that KLEVER galaxies are consistent with both the FMR and the FNR. This suggests that the depletion of N/O in high-$z$ galaxies when considered at a fixed M$_*$ is driven by the redshift-evolution of the mass-metallicity relation in combination with a near redshift-invariant N/O-O/H relation. Furthermore, the existence of an fundamental nitrogen relation suggests that the mechanisms governing the fundamental metallicity relation must be probed by not only O/H, but also N/O, suggesting pure-pristine gas inflows are not the primary driver of the FMR, and other properties such as variations in galaxy age and star formation efficiency must be important.

description: Angular distribution and correlation measurements are an essential part in nuclear structure experiments, especially when spectroscopic information of a specific nucleus is unknown. In most cases, the experimental determination of the spins, parities of the studied nuclear states, as well as the possible mixing between two electric/magnetic multipoles of a transition are determined using angular correlation measurements. In this work, the full effect of directional γ-correlations is simulated, by using the formal theory of angular distributions. The density matrix formalism along with its multipole expansions called statistical tensors is employed, enabling to perform a full simulation of the angular correlation effects in a cascade of an arbitrary number of γ transitions. A triple γ angular correlation simulation is demonstrated for the first time. The present approach was coupled with the Monte Carlo code FIFRELIN, which can simulate the de-excitation of fission fragments or of excited nuclei after neutron capture. It provides a complete description of the spatial distributions of all the γ rays in the cascade, that can be used for simulation purposes in various applications both in nuclear and particle physics. The potential for a novel approach in data analysis of angular correlation measurements is discussed thoroughly.

description: In spherical symmetry, solutions of the semiclassical Einstein equations belong to one of two possible classes. Both classes contain solutions that -- depending on the dynamic behavior of the horizon -- describe evaporating physical black holes or expanding white holes (trapped/anti-trapped regions that form in finite time of a distant observer). These solutions are real-valued only if the null energy condition (NEC) is violated in the vicinity of the Schwarzschild sphere. We review their properties and describe the only consistent black hole formation scenario. While the curvature scalars are finite on the outer apparent/anti-trapping horizon, it is still a weakly singular surface. This singularity manifests itself in a mild firewall. Near the inner apparent horizon, the NEC is satisfied. Models of static regular black holes are known to be unstable, but since dynamic models of regular black holes are severely constrained by self-consistency requirements, their stability requires further investigation.

description: Gravitational-wave (GW) signals from coalescing compact binaries carry enormous information about the source dynamics and are an excellent tool to probe unknown astrophysics and fundamental physics. Though the updated catalog of compact binary signals reports evidence for slowly spinning systems and unequal mass binaries, the data so far cannot provide convincing proof of strongly precessing binaries. Here, we use the GW inference library parallel Bilby to compare the performance of two waveform models for measuring spin-induced orbital precession. One of the waveform models incorporates both spin-precession effects and sub-dominant harmonics. The other model accounts for precession but only includes the leading harmonic. By simulating signals with varying mass ratios and spins, we find that the waveform model with sub-dominant harmonics enables us to infer the presence of precession in most cases accurately. In contrast, the dominant model often fails to extract enough information to measure precession. In particular, it cannot distinguish a face-on highly precessing binary from a slowly precessing binary system irrespective of the binary's mass ratio. As expected, we see a significant improvement in measuring precession for edge-on binaries. Other intrinsic parameters also become better constrained, indicating that precession effects help break the correlations between mass and spin parameters. However, the precession measurements are prior dominated for equal-mass binaries with face-on orientation, even if we employ waveform model including subdominant harmonics. In this case, doubling the signal-to-noise ratio does not help to reduce these prior induced biases. As we expect detections of highly spinning binary signals with misaligned spin orientations in the future, simulation studies like ours are crucial for understanding the prospects and limitations of GW parameter inferences.

description: In this work we propose a novel method to calculate mean first-passage times (MFPTs) for random walks on graphs, based on a dimensionality reduction technique for Markov State Models, known as local-equilibrium (LE). We show that for a broad class of graphs, which includes trees, LE coarse-graining preserves the MFPTs between certain nodes, upon making a suitable choice of the coarse-grained states (or clusters). We prove that this relation is exact for graphs that can be coarse-grained into a one-dimensional lattice where each cluster connects to the lattice only through a single node of the original graph. A side result of the proof generalises the well-known essential edge lemma (EEL), which is valid for reversible random walks, to irreversible walkers. Such a generalised EEL leads to explicit formulae for the MFPTs between certain nodes in this class of graphs. For graphs that do not fall in this class, the generalised EEL provides useful approximations if the graph allows a one-dimensional coarse-grained representation and the clusters are sparsely interconnected. We first demonstrate our method for the simple random walk on the $c$-ary tree, then we consider other graph structures and more general random walks, including irreversible random walks.

description: We present a new lossy compression algorithm for statistical floating-point data through a representation learning with binary variables. The algorithm finds a set of basis vectors and their binary coefficients that precisely reconstruct the original data. The optimization for the basis vectors is performed classically, while binary coefficients are retrieved through both simulated and quantum annealing for comparison. A bias correction procedure is also presented to estimate and eliminate the error and bias introduced from the inexact reconstruction of the lossy compression for statistical data analyses. The compression algorithm is demonstrated on two different datasets of lattice quantum chromodynamics simulations. The results obtained using simulated annealing show 3.5 times better compression performance than the algorithms based on a neural-network autoencoder and principal component analysis. Calculations using quantum annealing also show promising results, but performance is limited by the integrated control error of the quantum processing unit, which yields large uncertainties in the biases and coupling parameters. Hardware comparison is further studied between the previous generation D-Wave 2000Q and the current D-Wave Advantage system. Our study shows that the Advantage system is more likely to obtain low-energy solutions for the problems than the 2000Q.

Finite-size scaling functions of the phase transition in the ferromagnetic Ising model on random regular graphs

Publisher: name: arXiv
Year: 2021
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We discuss the finite-size scaling of the ferromagnetic Ising model on random regular graphs. These graphs are locally tree-like, and in the limit of large graphs, the Bethe approximation gives the exact free energy per site. In the thermodynamic limit, the Ising model on these graphs show a phase transition. This transition is rounded off for finite graphs. We verify the scaling theory prediction that this rounding off is described in terms of the scaling variable $[T/T_c -1] S^{1/2}$ (where $T$ and $T_c$ are the temperature and the critical temperature respectively, and $S$ is the number of sites in the graph), and $\textit{not}$ in terms of a power of the diameter of the graph, which varies as $\log S$. We determine the theoretical scaling functions for the specific heat capacity and the magnetic susceptibility of the absolute value of the magnetization in closed form and compare them to Monte Carlo simulations.

description: The aim of this scoping review is to systematically map and synthesize the existing empirical research regarding auditory-motor synchronization abilities in children with developmental coordination disorder by focusing on three timing modalities that underpin this process: auditory perceptual timing (perceptual judgment without movement), motor timing (self-paced actions), and auditory–motor timing (the timing of motor action is based on the auditory cue). We examine whether the unstable auditory-motor coupling shown by children with DCD is task-specific and whether their performance is associated with difficulties in auditory perceptual timing.

description: We present results on a multi-wavelength analysis of SDSS J025214.67-002813.7, a system which has been previously classified as a binary AGN candidate based on periodic signals detected in the optical light curves. We use available radio-X-ray observations of the system to investigate the true accretion nature. Analyzing new observations from XMM-Newton and NuSTAR, we characterize the X-ray emission and search for evidence of circumbinary accretion. Although the 0.5-10 keV spectrum shows evidence of an additional soft emission component, possibly due to extended emission from hot nuclear gas, we find the spectral shape consistent with a single AGN. Compiling a full multi-wavelength SED, we also search for signs of circumbinary accretion, such as a "notch" in the continuum due to the presence of minidisks. We find that the radio-optical emission agrees with the SED of a standard, radio-quiet, AGN, however there is a large deficit in emission blueward of ~1400 A. Although this deficit in emission can plausibly be attributed to a binary AGN system, we find that the SED of SDSS J0252-0028 is better explained by emission from a reddened, single AGN. However, future studies on the expected hard X-ray emission associated with binary AGN (especially in the unequal-mass regime), will allow for more rigorous analyses of the binary AGN hypothesis.

description: We discuss the dark gauge boson emission from neutron stars via nucleon-nucleon bremsstrahlung. Through the rigorous treatment of the effective field theory prescription and the thermal effect, we derive the relevant couplings of dark gauge bosons to hadrons in medium. As a specific example, the $U(1)_{\rm B-L}$ gauge boson scenario is chosen to investigate dark gauge boson emissivities during supernovae and cooling of young neutron stars. From the stellar cooling argument, we obtain the constraints on the $\rm B-L$ gauge coupling for given gauge boson masses in two observations: the duration of the supernova neutrino signal of SN1987A, and the inferred x-ray luminosity of the compact object in the remnant of SN1987A (NS1987A). In particular, the constraint from SN1987A on the $U(1)_{\rm B-L}$ gauge boson scenario is revisited. The excluded gauge coupling due to the emission of transverse polarizations is an order of magnitude enhanced compared to the previous derivation. There is also a newly excluded parameter space due to the emission of longitudinal polarizations.

Die Feldstudie untersucht die Aufnahme von Stickstoff bei Mais auf sorptionsstarker Schwarzerde bei steigender N-Gabe über 100 kg N/ha bis extrem hoher N-Zufuhr von 1300 kg N/ha Kalkammonsalpeter sowie deren Auswirkungen im Boden und auf den N-Stoffwechsel in der Pflanze. Im Einzelnen wurde hierbei die N-Aufnahme aus dem zugeführten Dünger unter Einbeziehung der N-Gehalte und der natürlichen N-Isotopenzusammensetzung im Spross von Silomais bestimmt. Zur Bewertung der N-Verwertung wurden in Maisblättern die Gehalte von zellulärem Ammonium und Nitrat sowie die Gehalte von N-Metaboliten (Amide) bestimmt und auch die Makronährstoffe N, P, K, Ca, Mg und S. Die hier in einer Vegetationsperiode durchgeführten Untersuchungen lassen sich zu folgenden Aussagen zusammenfassen: (1) Bei ausschließlich mineralischer Düngung von Mais auf sorptionsstarker Schwarzerde nimmt die Feldfrucht zur Produktion von Biomasse scheinbar mehr Stickstoff aus der Mineralisation organischer Substanz auf als aus dem zugeführten Dünger. (2) Überhöhte Düngung von Ammonium und Nitrat zu Silomais auf Schwarzerde führte zu Störungen im N-Stoffwechsel der Pflanze mit Ertragsdepressionen. (3) Zur Validierung der Aussagen sind mehrjährige Untersuchungen mit unterschiedlichen Maissorten auf verschiedenen Schwarzerden und variierenden Humusgehalten erforderlich.

F. 54/2 (2021): 145 – 156. This field study investigated the N uptake from inorganic fertilizer, e.g. calcium ammonium nitrate (CAN) in silage maize and effects of over-fertilization in the soil and in the plant metabolism. Ammonium and nitrate in soil, natural isotope ratios of total nitrogen in shoots as well as amino acids and macro nutrients were analysed. The results, which was obtained here in one growing season, can be summarized to the following statements: (I) In the case of exclusively mineral fertilisation of maize on sorptive black soil (Chernozem), the field crop apparently takes up more nitrogen from the mineralisation of organic matter for biomass formation than from the fertilizer supplied. (II) Over-fertilization of silage maize on black soil with ammonium and nitrate led to disturbances in the N metabolism of the plant with yield reductions. (II) To confirm the statements, multi-year studies with different maize varieties on various black earth and varying humus contents are necessary.

description: Modifying MoS2 thin films by additional elements shows great potential in order to adjust the property profile and to meet the increasing requirements regarding high wear resistance and low friction properties of industrial components. Within that context, MoSx:N:Mo thin films were deposited by a reactive hybrid dcMS/HiPIMS process. By systematically increasing the Mo target cathode power, an investigation of the structural and the mechanical properties was conducted to understand the evolution of the tribological behavior. A low Mo target cathode power of 1 kW is related to the formation of the preferential (002) MoS2 basal-plane and thus a low friction with µ = 0.2. With an increasing amount of Mo, the film loses its solid lubricant MoS2 properties and a nitride constitution of the thin film is developing due to the formation of crystalline Mo and MoN phases. Related to this transformation, the hardness and elastic modulus are increased, but the adhesion and the tribological properties are impaired. The film loses its plasticity and the generated film material is directly removed from the contact area during the sliding contact.

Subjects: Theses on morality of CE, climate engineering, ethics of climate engineering, ethical aspects, a moral point of view.

description: Nine theses on the morality of climate engineering: Should we engineer the climate? What speaks in favour of doing it and what against? Answers to these questions must be based in empirical science. But they must also engage with moral questions - those about duties, norms and values - if they want to do more than simply name what is feasible. In this contribution we defend 9 theses on the ethics of climate engineering (CE). We discuss which ethical aspects are of particular importance, what opportunities and risk matter most from a moral point of view, and how the debate on CE reflects upon us.

State-preserving container orchestration in failover scenarios
Creators: name: Schmidt, Henri
Publisher: name: TU Dortmund

description: Containers have been widely adopted for deployment of high availability applications and services. This adoption is in part due to the native support of fault tolerance mechanisms in container orchestration frameworks such as Kubernetes. While Kubernetes provides service replication as a fault tolerance mechanism for stateless applications, service replication does not satisfy requirements for stateful applications. Currently this shortcoming is addressed by data replication in databases. This requires a tight coupling and modification of the stateful application to support high availability. Thus, this thesis proposes a new Checkpoint/Restore (C/R) Kubernetes operator to achieve fault tolerance for stateful applications without any modification of the application. The operator takes a checkpoint in a configurable interval. In case of a fault a new application container is created automatically from the most recent checkpoint. We compare the proposed approach with a more conventional approach in which we pull and restore the application state from the application through an API. We measure the overhead of both methods, the service interruption and the recovery time in case of faults. We find the C/R Operator has similar performance in recovery time as the traditional approach, but does not need any application modification. The results signify C/R as a promising technology for a fault tolerance mechanism for stateful applications.
The smearing scale in Laguerre reconstructions of the correlation function

description: To a good approximation, on large cosmological scales the evolved two-point correlation function of biased tracers is related to the initial one by a convolution. For Gaussian initial conditions, the smearing kernel is Gaussian, so if the initial correlation function is parametrized using simple polynomials then the evolved correlation function is a sum of generalized Laguerre functions of half-integer order. This motivates an analytic Laguerre reconstruction algorithm which previous work has shown is fast and accurate. This reconstruction requires as input the width of the smearing kernel. We show that the method can be extended to estimate the width of the smearing kernel from the same dataset. This estimate, and associated uncertainties, can then be used to marginalize over the distribution of reconstructed shapes, and hence provide error estimates on the value of the distance scale which are not tied to a particular cosmological model. We also show that if, instead, we parametrize the evolved correlation function using simple polynomials, then the initial one is a sum of Hermite polynomials, again enabling fast and accurate deconvolution. If one is willing to use constraints on the smearing scale from other datasets, then marginalizing over its value is simpler for Hermite reconstruction, potentially providing further speed-up in cosmological analyses.

description: Borders have become a kind of meta-issue, capable of condensing a whole complex of fears and political concerns, including globalisation, loss of sovereignty, terrorism and irregular immigration. And Europe represents the paradigm of government policies exercised in and across borders, a government based on the exclusion and otherness of the migrants, in which subjects are framed according to their recognised capacity to move and live, to be and to enter into EUrope. After the long summer of migration of 2015, a new way of governing migration emerged, the humanitarian governance, in which care and control, protection and securitisation are both two sides of the same logic. In this thesis, we look at the military-humanitarian nature deployed at the Spanish-Moroccan border in Ceuta and Melilla and the birth of a “humanitarian border” to show the complex relationship of forces and contestation between control strategies and technologies and care and assistance practices. Thus, paradoxically, through the provision of humanitarianism, the systemic violence at the border is being perpetuated.

description: We present an experimental systematics study of the polarimetric method for measuring the vacuum magnetic birefringence based on a pair of rotating half-wave plates. The presence of a systematic effect at the same frequency as the sought for magneto-optical effect inhibits the use of strictly constant magnetic fields. We characterise this systematic, discuss its origin and propose a viable workaround.

Fighting to belong: diaspora soldiers, immigration, and national identity in Israel
Creators: name: Yohanani, Lior
Publisher: name: No Publisher Supplied

description: Over 30,000 Jewish foreign nationals have served in the Israel Defense Forces (IDF) since the new millennium. They come from over eighty countries, take Israeli citizenship, and become soldiers. What makes such people leave everything behind and participate in high-risk and high-cost military service? What makes some stay and settle in Israel and others leave? And what roles do diaspora organizations and state-sponsored actors play in convincing, facilitating, and supporting diaspora recruitment and wellbeing before, during, and after their service? Drawing on an original survey with over 1,100 soldiers and more than 100 in-depth interviews, this study examines the pathways of diaspora Jews to the IDF, the work of state and diaspora actors, and the interconnections between immigration and military service. I study these issues in three articles. The first article explores how diaspora people from different origins make decisions about military service in Israel. It shows that military service constitutes a crucial site for immigration and integration; that people from different origins are driven by very different reasons, but in all cases, diaspora military service is inextricably connected to immigration concerns. The second article explores how diaspora organizations construct national identity and meanings of belonging that are conducive to high-risk homeland military service. Using a three-case comparison, the article shows how homeland military service is being normalized and legitimized as a crucial element of belonging to Israeli nationhood. The third article explores the long-term effects of diaspora military service on identity and migration plans. Drawing on the theory of ethnic return migration, it develops the concept of military return migration. The article shows that military return migration operates differently than the standard ethnic return migration in the civilian sphere and labor market. Altogether, this research project contributes to our understanding of immigration and integration; meanings of citizenship, nationalism, and belonging; diaspora organizations and state-diaspora relations; and transnational high-risk activism. It shows that military service is an important site within which these topics and processes unfold and materialize in totalistic and extreme ways.
