description: The fast transitions between different types of quasi-periodic oscillations (QPOs) are generally observed in black hole transient sources (BHTs). We present a detailed study on the timing and spectral properties of the transitions of type-B QPOs in MAXI~J1348--630, observed by \emph{Insight}-HXMT. The fractional rms variability--energy relationship and energy spectra reveal that type-B QPOs probably originate from jet precession. Compared to weak power-law dominated power spectrum, when type-B QPO is present, the corresponding energy spectrum shows an increase in Comptonization component and the need for {\tt\string xillverCp} component, and a slight increase of height of the corona when using {\tt\string relxilllp} model. Therefore, we suggest that a coupled inner disk-jet region is responsible for the observed type-B QPOs transitions. The time scale for the appearance/disappearance of type-B QPOs is either long or short (seconds), which may indicate an instability of disk-jet structure. For these phenomena, we give the hypothesis that the Bardeen-Petterson effect causes disk-jet structure to align with BH spin axis, or that the disappearance of small-scale jets bound by the magnetic flux tubes lead to the disappearance of type-B QPOs. We observed three events regarding the B/C transitions, one of which occurred in a short time from $\sim 9.2$ Hz (C) to $\sim 4.8$ Hz (B). The energy spectral analysis for the other two transitions shows that when type-C QPO is present, the Comptonization flux is higher, the spectrum is harder and the inner radius of disk changes insignificantly. We suggest that type-C QPOs probably originate from relatively stronger jets or corona.

description: This document provides an operational status of FAIR-EASE prototype data lake testbed. The definition, architecture and specifications of FAIR-EASE data lake have been described in D4.1, D4.2 and D4.3 deliverables [3-5]. They come out of intense brainstorming activities that took place during the first two years of the project between the pilot use cases (WP5) and the technical work packages (WP2, WP3 and WP4).The first deployment of FAIR-EASE data lake testbed coincides with the first release of the FAIR-EASE Earth Analytics Lab (EAL) documented in deliverable D3.2, also due at Project Month 24 [2]. The two deliverables have been edited in a closely coordinated way to reflect the thorough exchanges between the two technical WPs.This document only provides a status of the deployment of FAIR-EASE innovative services on the different infrastructures and in the different environments that have been selected for hosting them. A more detailed description of these services is to be found in deliverable D3.2 [2]. The deployment status will be updated in Deliverable 4.5 that will describe the operational version of the data lake.

description: This dissertation aims at analyzing the effects of various assumptions that may affect the upstream transmission of the benefits of commodity checkoff programs. Despite the amount of econometric research on evaluation of the effects of checkoff programs for producer benefits, little empirical research has focused on the various simplifying assumptions often made in those analyses that may influence the rate and extent of the retail-to-farm transmission of generic advertising and promotion effects. The first part of this study is a qualitative analysis of the world soybean and soybean products markets. Then the conceptual model is proposed and discussed. A model of world soybean and soybean markets has been developed which relaxes all of the simplifying assumptions often made in analyses of commodity checkoff programs. The model is used to analyze the implications of those assumptions for the upstream transmission of the returns of the soybean checkoff program to producers. After estimating the econometric parameters of the model, the model has been simulated over history as a means of model validation. Then the model has been simulated again assuming that the U.S. soybean checkoff program had not existed over history. The differences from the simulation results by the baseline simulation are considered as the base case against which all other simulation results are compared. The base case results indicate that the soybean checkoff program has been highly effective over the study period returning $6.9 in revenue to soybean producers for every checkoff dollar spent. This upstream transmission of the benefits of the soybean checkoff program is analyzed through a series of simulations with the world soybean model in which the simplifying assumptions made by other checkoff program analyses. These are imposed on the model including the assumptions of no supply response, no price response, no government intervention, no free riders, no domestic supply chain linkages, no global supply chain linkages, no checkoff investments in production research and no promotion programs at multiple levels of the supply chain. The results of the scenario simulations provide the evidence that simplifying assumptions made in checkoff program analyses can seriously bias the calculation of the benefit-cost ratios (BCRs) for checkoff programs. Some assumptions have a tendency of overestimating the BCR for checkoff programs while others have a tendency of underestimating the BCR calculation. The implication of these findings is that analyses of checkoff programs must consider carefully the simplifying assumptions made to avoid seriously under- or over-estimating the returns of those programs to producers.

description: In this work, we present multiple new optimizations and heuristics for the determinization of Büchi automata that exploit a number of semantic and structural properties, most of which may be applied together with any determinization procedure. We built a prototype implementation where all the presented heuristics can be freely combined and evaluated them, comparing our implementation with the state-of-the-art tool spot on multiple data sets with different characteristics. Our results show that the proposed optimizations and heuristics can in some cases significantly decrease the size of the resulting deterministic automaton.

description: We discuss the options of the fall-back disk model of Anomalous X-Ray Pulsars (AXPs). We argue that the power-law index of the mass inflow rate during the propeller stage can be lower than those employed in earlier models. We take into account the effect of the super-critical mass inflow at the earliest stages on the inner radius of the disk and argue that the system starts as a propeller. Our results show that, assuming a fraction of the mass inflow is accreted onto the neutron star, the fall-back disk scenario can produce AXPs for acceptable parameters.

description: It was shown recently that the heart of a twin cotorsion pair ((S,T),(U,V)) on an extriangulated category is semi-abelian. We provide a sufficient condition for the heart to be integral and another for the heart to be quasi-abelian. This unifies and improves the corresponding results for exact and triangulated categories. Furthermore, if T=U, then we show that the Gabriel-Zisman localisation of the heart at the class of its regular morphisms is equivalent to the heart of the single twin cotorsion pair (S,T). This generalises and improves the known result for triangulated categories, thereby providing new insights in the exact setting.

description: We investigate a possible asymmetry in the statistical properties of the cosmic microwave background temperature field and to do so we construct an estimator aiming at detecting a dipolar modulation. Such a modulation is found to induce correlations between multipoles with $Δ\ell=1$. Applying this estimator, to the V and W bands of the WMAP data, we found a significant detection in the V band. We argue however that foregrounds and in particular point sources are the origin of this signal.

Une réduction de la taille des classes peut produire un effet bénéfique sur les performances scolaires des élèves, si cette réduction est importante et si elle s’applique à des classes de moins de 20 élèves. Selon le ministère de l’Éducation, l’effet de telles mesures de réduction demeure faible. Une expérimentation à grande échelle a alors été lancée pour tester l’effet d’une réduction importante de la taille des classes au niveau de Cours Préparatoire (CP) , pour les élèves défavorisés, notamment ceux évoluant en zone 2 d’éducation prioritaire.

description: We study the rare decay $Z_H \rightarrow H^0 γ$ at $\mathcal{O}(α_{\rm ew}^{3}α_s)$ accuracy including two-loop QCD corrections in the context of the littlest Higgs model (LHM) without $T$-parity. We revisit analytically and numerically the leading-order (LO) contributions of the one-loop diagrams induced by massive fermions, scalars and charged gauge bosons in the LHM, and further study the NLO QCD correction to this decay process. We perform the numerical calculation by taking the LHM input parameters $f=3,~4~\text{TeV}$ and $0.1< c <0.6$, and discuss the numerical results of the decay width up to the QCD NLO within the recent experimentally constrained LHM parameter space region. Our results show that the two-loop QCD correction always reduces the LO decay width and the top-induced QCD correction is the dominant contribution at the QCD NLO. For $f=4~\text{TeV}$ and $c=0.3$, the NLO QCD corrected decay width reaches $75.099~\text{keV}$ and the NLO QCD relative correction is about $-11.0\%$.

Model-Dependence of Shapiro Time Delay and the "Speed of Gravity/Speed of Light" Controversy

description: Fomalont and Kopeikin have recently succeeded in measuring the velocity-dependent component of the Shapiro time delay of light from a quasar passing behind Jupiter. While there is general agreement that this observation tests the gravitomagnetic properties of the gravitational field, a controversy has emerged over the question of whether the results depend on the speed of light, $c$, or the speed of gravity, $c_g$. By analyzing the Shapiro time delay in a set of ``preferred frame'' models, I demonstrate that this question is ill-posed: the distinction can only be made in the context of a class of theories in which $c\ne c_g$, and the answer then depends on the specific class of theories one chooses. It remains true, however, that for a large class of theories ``close enough'' to general relativity, the leading contribution to the time delay depends on $c$ and not $c_g$; within this class, observations are thus not yet accurate enough to measure the speed of gravity.

description: Context. Despite being a prominent subset of the exoplanet population discovered in the past three decades, the nature and provenance of sub-Neptune-sized planets are still one of the open questions in exoplanet science. Aims. For planets orbiting bright stars, precisely measuring the orbital and planet parameters of the system is the best approach to distinguish between competing theories regarding their formation and evolution. Methods. We obtained 69 new radial velocity observations of the mid-M dwarf G 9-40 with the CARMENES instrument to measure for the first time the mass of its transiting sub-Neptune planet, G 9-40 b, discovered in data from the K2 mission. Results. Combined with new observations from the TESS mission during Sectors 44, 45, and 46, we are able to measure the radius of the planet to an uncertainty of 3.4% (Rb = 1.900 +- 0.065 Re) and determine its mass with a precision of 16% (Mb = 4.00 +- 0.63 Me). The resulting bulk density of the planet is inconsistent with a terrestrial composition and suggests the presence of either a water-rich core or a significant hydrogen-rich envelope. Conclusions. G 9-40 b is referred to as a keystone planet due to its location in period-radius space within the radius valley. Several theories offer explanations for the origin and properties of this population and this planet is a valuable target for testing the dependence of those models on stellar host mass. By virtue of its brightness and small size of the host, it joins L 98-59 d as one of the two best warm (Teq ~ 400 K) sub-Neptunes for atmospheric characterization with JWST, which will probe cloud formation in sub-Neptune-sized planets and break the degeneracies of internal composition models.

description: This paper develops an innovative approach for calculating household nutrition indicators in a Computable General Equilibrium framework, using the flow of primary agri-food commodities through the global economy from farm to fork. It has been incorporated as a nutrition module in MAGNET. The method of tracing nutrients through the food system allows for making agriculture, the food supply chain and the economy as a whole nutrition-sensitive in scenario analyses. The validation of the nutrition outcomes in the base year with global data on nutrient consumption from the FAO reveals important differences which stem from differences in data and assumptions. Various solutions are identified to improve the calculations in the future. In the short run, correction factors are applied in the calculation of indicators in the nutrition module to capture and adjust the methodology for the remaining differences.

description: Security protocols stipulate how the remote principals of a computer network should interact in order to obtain specific security goals. The crucial goals of confidentiality and authentication may be achieved in various forms, each of different strength. Using soft (rather than crisp) constraints, we develop a uniform formal notion for the two goals. They are no longer formalised as mere yes/no properties as in the existing literature, but gain an extra parameter, the security level. For example, different messages can enjoy different levels of confidentiality, or a principal can achieve different levels of authentication with different principals. The goals are formalised within a general framework for protocol analysis that is amenable to mechanisation by model checking. Following the application of the framework to analysing the asymmetric Needham-Schroeder protocol, we have recently discovered a new attack on that protocol as a form of retaliation by principals who have been attacked previously. Having commented on that attack, we then demonstrate the framework on a bigger, largely deployed protocol consisting of three phases, Kerberos.

description: Abridged. We observed the 40 Myr old star DS Tuc A with XMM-Newton and recorded two X-ray bright flares, with the second event occurring about 12 ks after the first one. Their duration from the rise to the end of the decay was of about 8-10 ks in soft X-rays (0.3-10 keV). The flares were also recorded in the band 200-300 nm with the UVM2 filter of the Optical Monitor. The duration of the flares in UV was about 3 ks. The observed delay between the peak in the UV band and in X-rays is a probe of the heating phase followed by the evaporation and increase of density and emission measure of the flaring loop. The coronal plasma temperature at the two flare peaks reached 54-55 MK. The diagnostics based on temperatures and time scales of the flares applied to these two events allow us to infer a loop length of 5-7 x 10^10 cm, which is about the size of the stellar radius. We also infer values of electron density at the flare peaks of 2.3-6.5 x 10^11 cm^-3 , and a minimum magnetic field strength of order of 300-500 G needed to confine the plasma. The energy released during the flares was of order of 5-8 x 10^34 erg in the band 0.3-10 keV and 0.9-2.7 x 10^33 erg in the UV band (200-300 nm). We speculate that the flares were associated with Coronal Mass Ejections (CMEs) that hit the planet about 3.3 hr after the flares and dramatically increasing the rate of evaporation of the planet. From the RGS spectra we retrieved the emission measure distribution and the abundances of coronal metals during the quiescent and the flaring states. In agreement with what inferred from time resolved spectroscopy and EPIC spectra, also from the analysis of RGS spectra during the flares we infer a high electron density.

description: Abstract

The antioxidant effect and influence of a composition consisting of monoammonium salt of glycyrrhizic acid (MASGA) and amino acids - cysteine, methionine, and tryptophan on the bioenergetics of rat liver mitochondria in paracetamol-induced liver damage in rats were studied. It has been established that paracetamol causes a significant increase in the liver homogenate of diene conjugates and conjugated trienes, as well as a secondary product of lipid peroxidation (LPO) - malondialdehyde (MDA). In the liver mitochondria, under the influence of paracetamol, there is a decrease in respiration and oxidative phosphorylation processes. The introduction of the studied composition to hepatitis animals reduced the content of primary and secondary LPO products and partially restored the functional state of the mitochondria.

description: This article explains incentives that individuals face when deciding whether to support legislation on farm-animal treatment. We analyze precinct- and town-level voting patterns in two successful referendum votes (California’s Prop 2 and Massachusetts’s Question 3) that restricted animal-housing practices. In both cases, support for the referendum was positively correlated with support for the Democratic candidate for president and negatively correlated with employment in agriculture; support for Question 3 increased with income. We use our regression results to predict how voters in other U.S. states would have voted had they faced similar referendums in 2008 and 2016.

description: Using HST narrow-band Hα images of supernova remnant 0509-67.5 taken {\sim}10 years apart, we measure the forward shock (FS) proper motions (PMs) at 231 rim locations. The average shock radius and velocity are 3.66 {\pm} 0.036 pc and 6315 {\pm} 310 km s{^{-1}}. Hydrodynamic simulations, recast as similarity solutions, provide models for the remnant's expansion into a uniform ambient medium. These are coupled to a Markov chain Monte Carlo (MCMC) analysis to determine explosion parameters, constrained by the FS measurements. For specific global parameters, the MCMC posterior distributions yield an age of 315.5 {\pm} 1.8 yr, a dynamical explosion center at 5h09m31s.16s -67{^\circ}31{^\prime}17.1{^{\prime\prime}} and ambient medium densities at each azimuth ranging from 3.7-8.0 {\times} 10{^{-25}} g cm{^{-3}}. We can detect stellar PMs corresponding to speeds in the LMC of 770 km s{^{-1}} or more using the H$α$ images. Five stars in the remnant show measurable PMs but none appear to be moving radially from the center, including a prominent red star 4.6{^{\prime\prime}} from the center. Using coronal [Fe XIV] λ5303 emission as a proxy for the reverse shock location, we constrain the explosion energy (for a compression factor of 4) to a value of E = (1.30 {\pm} 0.41) {\times} 10{^{51}} erg for the first time from shock kinematics alone. Higher compression factors (7 or more) are strongly disfavored based on multiple criteria, arguing for inefficient particle acceleration in the Balmer shocks of 0509-67.5.

Dans le cadre de cette recherche, nous avons conduit des entretiens semi-dirigés avec 35 professionnels encadrant les élèves dans huit instituts de Lyon et de Paris. Ce sont les deux volets – objectifs et pratiques pédagogiques – que nous cherchons à montrer à travers l’évocation concrète des pratiques mises en oeuvre dans ces établissements peu connus. L’analyse des propos des éducateurs concernant les apprentissages professionnels permet de montrer comment apparaissent, à travers des pratiques et des réalisations présentées comme très modestes, des objectifs déclarés d’une professionnalisation authentique dont les ambitions font penser aux exigences requises pour les professions à pratiques prudentielles.

description: We investigate the impacts of Comprehensive Economic and Trade Agreement (CETA) liberalizations of trade and investment barriers on processed food markets. Using a four-region monopolistic competition model with heterogeneous food-processing firms that incorporates domestically operating, exporting, and multinational enterprise (MNE) firms, we quantify the effects of tariff elimination, fixed trade cost reduction, and foreign direct investment (FDI) cost reduction under CETA on prices, domestic sales, bilateral trade flows, affiliate sales, productivity, number of firms, and aggregate output. Our results highlight that trade liberalization promotes bilateral exports but reduces foreign affiliate sales, and, in contrast, lower FDI costs expand MNE affiliate sales but curtail bilateral exports.

description: We examine the bound-state and free-state contributions to the density of states in a three-dimensional electron gas with a two-dimensional interface with Rashba spin-orbit coupling. Confinement of electrons to the interface is achieved through the inclusion of an attractive potential in the interface. Motivation for our research comes from interest in heterostructure materials that exhibit the Edelstein and inverse Edelstein effects on surfaces or interfaces due to large Rashba spin-orbit coupling. By modifying the Hamiltonian of a three-dimensional free electron gas to include an interface with Rashba spin-orbit coupling and an attractive potential, we are able to calculate the bound-state and free-state wavefunctions and corresponding density of states analytically. We find that one of the spin-split energy bands in the interface has an upper bound, resulting in an enhancement of the Edelstein and inverse Edelstein effect.

description: Recently reported measurements of specific heat on the compound Mn-formate di-Urea (Mn-f-2U) by Takeda et al. [Phys. Rev. B 63, 024425 (2001)] are considered. As a model to describe the overall thermodynamic behavior of such compound, the easy-axis two-dimensional Heisenberg antiferromagnet is proposed and studied by means of the 'pure quantum self-consistent harmonic approximation' (PQSCHA). In particular it is shown that, when the temperature decreases, the compound exhibits a crossover from 2D-Heisenberg to 2D-Ising behavior, followed by a 2D-Ising-like phase transition, whose location allows to get a reliable estimate of the easy-axis anisotropy driving the transition itself. Below the critical temperature T_N=3.77 K, the specific heat is well described by the two-dimensional easy-axis model down to a temperature T*=1.47 K where a T^3-law sets in, possibly marking a low-temperature crossover of magnetic fluctuations from two to three dimensions.

description: La rentrée à la maternelle constitue la première transition scolaire des enfants. Les défis de cette première rentrée sont augmentés lorsque les enfants ont des besoins particuliers. À la complexité des réponses à apporter à leurs besoins sur le plan intellectuel, moteur, social, langagier, etc. s’ajoute la coordination d’intervenants variés. Dans le cadre d’une recherche-action, des acteurs intersectoriels ont été regroupés en trois réseaux distincts afin de planifier la transition vers le préscolaire de trois enfants ayant des besoins spécifiques Le travail en réseau a fait l’objet d’une analyse spécifique en utilisant la sociologie de la traduction comme cadre d’analyse. Les réseaux étaient constitués des parents et des acteurs provenant des milieux scolaire, de la santé et des services sociaux et des services de garde. La planification de la transition a été l’occasion d’observer une évolution des pratiques entre les acteurs des trois réseaux étudiés. Ces acteurs se sont unis autour d’une cause commune, avec la visée de faire vivre une transition de qualité aux enfants ciblés selon les diverses situations.

description: Short time approximation is developed for system-environmental bath mode interactions involving a general non-Hermitian system operator $Λ$, and its conjugate, $Λ^\dagger$, in order to evaluate onset of decoherence at low temperatures in quantum systems interacting with environment. The developed approach is complementary to Markovian approximations and appropriate for evaluation of quantum computing schemes. Example of a spin system coupled to a bosonic heat bath via $Λ\propto σ_-$ is worked out in detail.

description: We report the discovery of two transiting exoplanets from the WASP survey, WASP-150b and WASP-176b. WASP-150b is an eccentric ($e$ = 0.38) hot Jupiter on a 5.6 day orbit around a $V$ = 12.03, F8 main-sequence host. The host star has a mass and radius of 1.4 $\rm M_{\odot}$ and 1.7 $\rm R_{\odot}$ respectively. WASP-150b has a mass and radius of 8.5 $\rm M_J$ and 1.1 $\rm R_J$, leading to a large planetary bulk density of 6.4 $\rm ρ_J$. WASP-150b is found to be $\sim3$ Gyr old, well below its circularisation timescale, supporting the eccentric nature of the planet. WASP-176b is a hot Jupiter planet on a 3.9 day orbit around a $V$ = 12.01, F9 sub-giant host. The host star has a mass and radius of 1.3 $\rm M_{\odot}$ and 1.9 $\rm R_{\odot}$. WASP-176b has a mass and radius of 0.86 $\rm M_J$ and 1.5 $\rm R_J$ respectively, leading to a planetary bulk density of 0.23 $\rm ρ_J$.

description: Active asteroids show (typically transient) cometary activity, driven by a range of processes. A sub-set, sometimes called main-belt comets, may be driven by sublimation and so could be useful for tracing the present-day distribution of asteroid ice. Object P/2018 P3 has a Tisserand parameter 3.096 but a high eccentricity 0.415, placing it within the dynamical boundary between asteroids and comets. We aim to determine the cause of activity (sublimation or something else) and assess the dynamical stability of P3, in order to better constrain the intrinsic ice content in the main belt. We obtained Hubble Space Telescope images of P3 at the highest angular resolution. We compared the observations with a Monte Carlo model of dust dynamics. We identified and analyzed archival CFHT (2013) and NEOWISE (2018) data. In addition, we numerically integrated the orbits of P3 clones for 100 Myr. P3 has been recurrently active near two successive perihelia (at 1.76 AU), indicative of a sublimation origin. The absence of 4.6 um band excess indicates zero or negligible CO or CO2 gas production from P3. The properties of the ejected dust are remarkably consistent with those found in other main-belt comets (continuous emission of ~0.05-5 mm particles at 0.3-3 m/s speeds), with mass-loss rates of >~2 kg/s. The orbit of P3 is unstable on timescales ~10 Myr. We speculate that P3 has recently arrived from a more stable source (either the Kuiper Belt or elsewhere in the main belt) and has been physically aged at its current location, finally becoming indistinguishable from a weakly sublimating asteroid in terms of its dust properties. Whatever the source of P3, given the dynamical instability of its current orbit, P3 should not be used to trace the native distribution of asteroid ice.

description: We demonstrate the first step of a complete program, which consists in establishing an x-ray energy standard scale with the use of few-body atoms, in the few keV range. Light pionic and muonic atoms as well as one and two-electron ions from electron-cyclotron ion sources are used. The transition energies are calculable from quantum-electrodynamics, meaning that only a very limited subset need be measured and compared with theory, while providing a large number of standard lines. Here we show that circular transitions in pionic neon atoms, completely stripped from their electrons, reveal spectral lines which are narrow, symmetric, and well reproducible. We use these lines for the energy determination of transition energies in complex electronic systems, like the K1,2 transitions in metallic Ti, which may serve as secondary standard.

description: The Micro Solar-Flare Apparatus (MiSolFA) is a compact X-ray imaging spectrometer designed for a small 6U micro-satellite. As a relatively inexpensive yet capable Earth-orbiting instrument, MiSolFA is designed to image the high-energy regions of solar flares from a different perspective than that of Solar Orbiter's STIX, operating from a highly elliptical heliocentric orbit. Two instruments working together in this way would provide a 3-dimensional view of X-ray emitting regions and can bypass the dynamic range limitation preventing simultaneous coronal and chromospheric imaging. Stereoscopic X-ray observations would also contain valuable information about the anisotropy of the flare-accelerated electron distribution. To perform these types of observations, MiSolFA must be capable of imaging sources with energies between 10 and 100 keV, with 10 arcsec angular resolution. MiSolFA's Imager will be the most compact X-ray imaging spectrometer in space. Scaling down the volume by a factor of ten from previous instrument designs requires special considerations. Here we present the design principles of the MiSolFA X-ray optics, discuss the necessary compromises, and evaluate the performance of the Engineering Model.
