description: It is generally accepted that the non-linear, dynamical evolution of magnetic fields in the interior of neutron stars plays a key role in the explanation of the observed phenomenology. Understanding the transfer of energy between toroidal and poloidal components, or between different scales, is of particular relevance. In this letter, we present the first 3D simulations of the Hall instability in a neutron star crust, confirming its existence for typical magnetar conditions. We confront our results to estimates obtained by a linear perturbation analysis, which discards any interpretation as numerical instabilities and confirms its physical origin. Interestingly, the Hall instability creates locally strong magnetic structures that occasionally can make the crust yield to the magnetic stresses and generates coronal loops, similarly as solar coronal loops find their way out through the photosphere. This supports the viability of the mechanism, which has been proposed to explain magnetar outbursts.

Real estate listings and their usefulness for hedonic regressions

description: Real estate platforms provide a new source of data which has already been used as a substitute for transaction data in hedonic regression applications. This paper asks whether it is valid to do so in the established research areas of (1) willingness to pay estimation, (2) automated valuations, and (3) price index construction. It therefore compares listings and transaction data and regression results derived from them. We find that ask prices stochastically dominate sale prices, mainly because the composition of characteristics differs between the two data sets. But estimates of implicit prices also differ. As a result, willingness to pay estimates from listings data can be widely off when compared with estimates from transaction data. Listings data are not very useful to predict market values of individual houses either, as these predictions suffer from upward bias and large error variance. We find, however, that an ask price index complements a sale price index, as it is useful for nowcasting.
From the Ashes of History: Trauma, National Identity and State-Building in India and Israel

description: Despite violence’s enormous role in international politics, mainstream International Relations (IR) scholarship tends to focus primarily on its immediate impacts on the balance of power, neglecting the lingering impact of trauma. In recent years, a vibrant (albeit inchoate) literature has developed on trauma’s legacy in international politics, but it has largely focused on trauma’s sociocultural impacts in Western contexts, neglecting how trauma’s material reification can exacerbate its effects in developing societies. This thesis theorizes collective trauma holistically as a vital force in international politics, embedded in the inequalities, injustices and institutions that define the international system. It begins by theorizing identity discourses as comprised of competing narrations of memory (including traumatic memory). The identity narratives that constitute these discourses weave together experience and knowledge, bridging the divide between the individual and the social to create the logics of policymaking. The second chapter explains how collective traumas complicate identity discourses due to the complexities inherent in their narration. The thesis then turns to two case studies of post-independence developing states that demonstrate this theorization’s utility in analysis. First, I argue that, in post-independence India, economic nationalist discourse interpreted the diverse suffering imperialism generated as a collective trauma. This trauma’s narration legitimated a consensus logic that autarky was vital to India’s security, influencing foreign economic policymaking for decades. Next, I examine the role of Holocaust memory in Israeli foreign policy discourse after independence. I argue that the 1961 trial of Adolf Eichmann augured a shift in this discourse from official repression to what I term ‘victimhood nationalism’, an identity that drew on collective trauma to legitimate the projection of grievances onto Israel’s enemies in the Arab world. The thesis concludes by reflecting on how deeper understanding of trauma studies’ diverse interdisciplinary insights can further existing debates in international politics and history, as well as how examination of trauma’s macro-political dimensions can further the field of trauma studies.

description: Models of magnetohydrodynamic (MHD) equilibia that for computational convenience assume the existence of a system of nested magnetic flux surfaces tend to exhibit singular current sheets. These sheets are located on resonant flux surfaces that are associated with rational values of the rotational transform. We study the possibility of eliminating these singularities by suitable modifications of the plasma boundary, which we prescribe in a fixed boundary setting. We find that relatively straightforward iterative procedures can be used to eliminate weak current sheets that are generated at resonant flux surfaces by the nonlinear interactions of resonating wall harmonics. These types of procedures may prove useful in the design of fusion devices with configurations that enjoy improved stability and transport properties.
Enhancing social dimensions in citizen science: SDGs and social tipping points

description: The pursuit of sustainable goals entails substantial technological and scientific advancements. However, commitment and cooperation from vast segments of our societies is also required to turn the efforts into actions. Just a mention from a straightforward example: climate stabilization is not only a scientific and technological task, it also depends on activating processes of social change on several levels. An interesting concept to raise here is the social tipping point, which is a point where a group rapidly and dramatically changes its behavior by widely adopting a previously rare practice. The concept, taken from the field of behavioural sciences, has strongly emerged in climate literature but it is potentially of interest to face any other urgent societal challenge. Due to its participatory spirit, citizen science provides a framework to further reflect on the notion of social tipping point and integrate social dimensions into any specific SDG oriented research activities. Grounded on our current CoAct EU project, the presentation will discuss a general model for a citizen social science which offers communities, groups or individuals the possibility to directly intervene into scientific research and to then actively contribute to SDGs. Citizen social science engages citizen bodies concerned with specific social issues in co-research and imagines the possibility to support demands of the public with scientific evidence. The joint effort represents itself a way to reinterpret scientific practice, much closer to collective action and policy making and very much linked to public debate. The presentation will take experiences from contexts such as climate justice, mental health care provision, air pollution exposure, gender biased interactions in public spaces among others to encourage a further enhancement of social dimensions in citizen science practices if they want to more effectively support SDGs.
Milky Way Zero-Point Calibration of the JAGB Method: Using Thermally Pulsing AGB Stars in Galactic Open Clusters

description: We present a new calibration of the J-band absolute magnitude of the JAGB method based on thermally pulsing AGB stars that are members of Milky Way open clusters, having distances and reddenings, independently compiled and published by Marigo et al (2022). 17 of these photometrically-selected J-Branch AGB stars give M_J = -6.40 mag with a scatter of +/-0.40 mag, and a sigma on the mean of +/-0.10 mag. Combining the Milky Way field carbon star calibration of Lee et al. (2021) with this determination gives a weighted average of M_J(MW) = -6.19 +/- 0.04 mag (error on the mean). This value is statistically indistinguishable from the value determined for this population of distance indicators in the LMC and SMC, giving further evidence that JAGB stars are extremely reliable distance indicators of high luminosity and universal applicability. Combining the zero points for JAGB stars in these three systems, a value of M_J = -6.20 +/- 0.01 (stat) +/- 0.04 (sys) mag becomes our best current estimate of the JAGB zero point and its associated errors. Finally, we note that no evidence is found for any statistically significant dependence of this zero point on metallicity.

description: In this paper we construct star products on Marsden-Weinstein reduced spaces in case both the original phase space and the reduced phase space are (symplectomorphic to) cotangent bundles. Under the assumption that the original cotangent bundle $T^*Q$ carries a symplectique structure of form $ω_{B_0}=ω_0 + π^*B_0$ with $B_0$ a closed two-form on $Q$, is equipped by the cotangent lift of a proper and free Lie group action on $Q$ and by an invariant star product that admits a $G$-equivariant quantum momentum map, we show that the reduced phase space inherits from $T^*Q$ a star product. Moreover, we provide a concrete description of the resulting star product in terms of the initial star product on $T^*Q$ and prove that our reduction scheme is independent of the characteristic class of the initial star product. Unlike other existing reduction schemes we are thus able to reduce not only strongly invariant star products. Furthermore in this article, we establish a relation between the characteristic class of the original star product and the characteristic class of the reduced star product and provide a classification up to $G$-equivalence of those star products on $(T^*Q,ω_{B_0})$, which are invariant with respect to a lifted Lie group action. Finally, we investigate the question under which circumstances `quantization commutes with reduction' and show that in our examples non-trivial restrictions arise.

Hard Synchrotron Spectra from Magnetically Dominated Plasma Turbulence

description: Synchrotron emission from astrophysical nonthermal sources usually assumes that the emitting particles are isotropic. By means of large-scale two- and three-dimensional particle-in-cell simulations, we demonstrate that the dissipation of magnetically-dominated ($σ_0\gg1$) turbulence in pair plasmas leads to strongly anisotropic particle distributions. At Lorentz factors $\sim σ_0 γ_{th0}$ (here, $γ_{th0}$ is the initial Lorentz factor), the particle velocity is preferentially aligned with the local magnetic field; instead, the highest energy particles are roughly isotropic. This energy-dependent anisotropy leads to a synchrotron spectral flux $νF_ν\propto ν^s$ that is much harder than for isotropic particles. Remarkably, for $σ_0\gg1$ we find that the solid-angle-averaged spectral slope in the slow cooling regime is $s\sim 0.5-0.7$ for a wide range of turbulence fluctuations, $0.25\lesssim δB_{\rm rms0}^2/B_0^2\lesssim 4$, despite significant variations in the power-law energy spectrum of nonthermal particles. This is because weaker turbulence levels imprint a stronger degree of anisotropy, thereby counteracting the effect of the steeper particle spectrum. The synchrotron spectral slope may be even harder, $s\gtrsim 0.7$, if the observer is in the plane perpendicular to the mean magnetic field. Our results are independent of domain size and dimensionality. Our findings may help explaining the origin of hard synchrotron spectra of astrophysical nonthermal sources, most notably the radio spectrum of Pulsar Wind Nebulae.

description: We carry out a search for tidal tails in a sample of open clusters with known relatively elongated morphology. We identify the member stars of these clusters from the precise astrometric and deep photometric data from $Gaia$ Early Data Release 3 using the robust membership determination algorithm, ML-MOC. We identify 46 open clusters having a stellar corona beyond the tidal radius, 20 of which exhibit extended tails aligned with the cluster orbit direction in galactocentric coordinates. Notably we find NGC 6940 (at a distance of $\sim1$ kpc) is the furthest open cluster exhibiting tidal tails that are $\sim50$ pc from its center, while also identifying $\sim40$ pc long tidal tails for the nearby Pleiades. Using the minimum spanning tree length for the most massive stars relative to all cluster members, we obtain the mass segregation ratio ($\rmλ_{MSR}$) profiles as a function of the number of massive stars in each cluster. From these profiles, we can classify the open clusters into four classes based on the degree of mass segregation experienced by the clusters. We find that clusters in the most mass segregated classes are the oldest on average and have the flattest mass function slope. Of the 46 open clusters studied in this work, 41 exhibit some degree of mass segregation. Furthermore, we estimate the initial masses (M$\rm_{i}$) of these open clusters finding that some of them, having M$\rm_{i}\gtrsim 10^{4} M_{\odot}$, could be the dissolving remnants of Young Massive Clusters.

description: The inner-most region of the Seyfert galaxy NGC 2992 has long been suspected to be the location of intense AGN-host galaxy interaction, but photon pile-up in previous high-resolution observations hampered the study of soft X-ray excess and the interaction near its nucleus. We present an X-ray imaging spectroscopic analysis of the circumnuclear ($1^{\prime\prime}$--$3^{\prime\prime}$) region of NGC 2992 using the zeroth-order image of a 135 ks grating observation obtained with Chandra, which captured the nucleus in a historically low flux state. Extended soft X-ray emission is detected in the circumnuclear region with observed luminosity $L_{\rm X} \sim 7 \times 10^{39}\rm\ erg\ s^{-1}$. The majority of previously puzzling detection of soft excess could be associated with the outflow, indicated by the morphological correspondences between soft X-ray emission and figure-eight-shaped radio bubbles. An anomalous narrow emission line with the centroid energy $\sim4.97$ keV is found. If attributed to redshifted highly ionized iron emission (e.g., Fe xxv), the required outflow velocity is $\sim0.23\,c$. An alternative explanation is that this line emission could be produced by the nuclear spallation of iron. We also find asymmetric extended Fe K$α$ emission along the galactic disk, which could originate from reflection by cold gas on $\sim 200$ pc scale.

Giant dispersion of critical currents in superconductor with fractal clusters of a normal phase

description: The influence of fractal clusters of a normal phase on the dynamics of a magnetic flux trapped in a percolative superconductor is considered. The critical current distribution and the current-voltage characteristics of fractal superconducting structures in the resistive state are obtained for an arbitrary fractal dimension of the cluster boundaries. The range of fractal dimensions, where the dispersion of critical currents becomes infinite, is found. It is revealed that the fractality of clusters depresses of the electric field caused by the magnetic flux motion thus increasing the critical current value. It is expected that the maximum current-carrying capability of a superconductor can be achieved in the region of giant dispersion of critical currents.

description: The CDEX (China Dark matter Experiment) is currently in the stage to upgrade to approximately 10 kg HPGe (High Purity Germanium) detectors (CDEX-10) in CJPL (China Jinping Underground Laboratory) and aims to detect the WIMP (Weakly Interacting Massive Particles). Six analog signals and one inhibited signal are outputted from preamplifier by one HPGe detector (~1 kg) of CDEX-10. The analog signals are conditioned with two 6-us and one 12-us shaping amplifiers, and three timing amplifiers respectively. The inhibited signal is used for trigger. The analog signals from shaping and timing amplifiers are digitized to obtain energy spectrum and rise-time distribution. The rise-time distribution is used to discriminate surface, bulk, and very bulk events, which can help to supress the background level in dark matter detection. Composed of commercial modules, the previous DAQ (Data Acquisition Systems) is insufficient in discriminating between bulk and very bulk events due to the limited sampling rate (100 MSPS). Besides, as number of channel increases, the system will be simplified by integrating the trigger logic in FPGA (Field Programmable Gate Array). In this paper, a prototype named RAIN4HPGe is designed with pulse digitizer and readout electronics, integrating 14-Bit 100 MSPS ADCs (Analog-to-Digital Converters), 12-Bit 1 GSPS ADCs, FPGA etc.. The RAIN1000Z1 readout module based on ZYNQ SoC (System on Chip) is used for readout over Gigabit Ethernet. Better energy resolution, e.g. improving from 558 eV to 474 eV @122 keV, can be achieved by RAIN4HPGe compared to previous DAQ (Data Acquisition Systems) with commercial solution. Moreover, the discrimination performance of bulk, and very bulk events has been improved by RAIN4HPGe with 1 GSPS ADC.

description: The absorption features of optically generated, short-lived small bound electron polarons are inspected in congruent lithium tantalate, ${\rm LiTaO}_3$ (LT), in order to address the question whether it is possible to localize electrons at interstitial ${\rm Ta_V}$:${\rm V_{Li}}$ defect pairs by strong, short-range electron-phonon coupling. Solid-state photoabsorption spectroscopy under light exposure and density functional theory are used for an experimental and theoretical access to the spectral features of small bound polaron states and to calculate the binding energies of the small bound ${\rm Ta}_{\rm Li}^{4+}$ (antisite) and ${\rm Ta}_{\rm V}^{4+}$:${\rm V_{Li}}$ (interstitial site) electron polarons. As a result, two energetically well separated ($ΔE \approx 0.5\,{\rm eV}$) absorption features with a distinct dependence on the probe light polarization and peaking at $1.6\,{\rm eV}$ and $2.1\,{\rm eV}$ are discovered. We contrast our results to the interpretation of a single small bound ${\rm Ta}_{\rm Li}^{4+}$ electron state with strong anisotropy of the lattice distortion and discuss the optical generation of interstitial ${\rm Ta}_{\rm V}^{4+}$:${\rm V_{Li}}$ small polarons in the framework of optical gating of ${\rm Ta}_{\rm V}^{4+}$:${\rm Ta}_{\rm Ta}^{4+}$ bipolarons. We can conclude that the appearance of carrier localization at $\mathrm{Ta_V}$:${\rm V_{Li}}$ must be considered as additional intermediate state for the 3D hopping transport mechanisms at room temperature in addition to ${\rm Ta_{Li}}$, as well, and, thus, impacts a variety of optical, photoelectrical and electrical applications of LT in nonlinear photonics. Furthermore, it is envisaged that LT represents a promising model system for the further examination of the small-polaron based photogalvanic effect in polar oxides with the unique feature of two, energetically well separated small polaron states.
Observational Constraints on the Common Envelope Phase

description: The common envelope phase was first proposed more than forty years ago to explain the origins of evolved, close binaries like cataclysmic variables. It is now believed that the phase plays a critical role in the formation of a wide variety of other phenomena ranging from type Ia supernovae through to binary black holes, while common envelope mergers are likely responsible for a range of enigmatic transients and supernova imposters. Yet, despite its clear importance, the common envelope phase is still rather poorly understood. Here, we outline some of the basic principles involved, the remaining questions as well as some of the recent observational hints from common envelope phenomena - namely planetary nebulae and luminous red novae - which may lead to answering these open questions.

description: A wave turbulence theory is developed for inertial electron magnetohydrodynamics (IEMHD) in the presence of a relatively strong and uniform external magnetic field $\boldsymbol{B_0} = B_0 \hat{\boldsymbol{e}}_\|$. This regime is relevant for scales smaller than the electron inertial length $d_e$. We derive the kinetic equations that describe the three-wave interactions between inertial whistler or kinetic Alfvén waves. We show that for both invariants, energy and momentum, the transfer is anisotropic (axisymmetric) with a direct cascade mainly in the direction perpendicular ($\perp$) to $\boldsymbol{B_0}$. The exact stationary solutions (Kolmogorov-Zakharov spectra) are obtained for which we prove the locality. We also found the Kolmogorov constant $C_K \simeq 8.474$. In the simplest case, the study reveals an energy spectrum in $k_\perp^{-5/2} k_\|^{-1/2}$ and a momentum spectrum enslaved to the energy dynamics in $k_\perp^{-3/2} k_\|^{-1/2}$. These solutions correspond to a magnetic energy spectrum $\sim k_\perp^{-9/2}$, which is steeper than the EMHD prediction made for scales larger than $d_e$. We conclude with a discussion on the application of the theory to space plasmas.

description: Background: The Rapid Syllable Transition (ReST) treatment is an effective intervention designed to address the planning and programming disorder found in childhood apraxia of speech. To date, no study has considered its use with children who speak languages other than English.Aim: This pilot study aimed to examine the use of ReST treatment with Italian children. We hypothesized that the ReST approach would improve the overall accuracy of the targeted behaviors of lexical stress, smoothness, and phonemic accuracy, whereas phonemic and phonetic accuracy of untreated items would remain stable.Method: Two monolingual Italian-speaking children with childhood apraxia of speech received therapy in 12 one-hour sessions, 2–3 times per week, using a single-case experimental design. The treatment procedures used in English were replicated in Italian with one change: In English, two stress patterns are treated. Italian commonly uses three stress patterns; therefore, the stimuli were modified accordingly. Accuracy of articulation, lexical stress, and smoothness were assessed at pretreatment and 1 day, 1 week, and 4 months posttreatment in treated and untreated pseudowords and in real words and sentences.Results: Both children improved on treated pseudowords and real words with moderate effect sizes, but only one child generalized to untreated pseudowords. Maintenance of treatment results was observed in both participants. Articulation of control phonemes did not change.Conclusions: ReST treatment in Italian is feasible, and a treatment effect was found, showing that its use may be valid in languages other than English. Further research is required.

An Observational Diagnostic for Ultraluminous X-Ray Sources

description: We consider observational tests for the nature of Ultraluminous X-ray sources (ULXs). These must distinguish between thermal-timescale mass transfer on to stellar-mass black holes leading to anisotropic X-ray emission, and accretion on to intermediate-mass black holes. We suggest that long-term transient behavior via the thermal-viscous disk instability could discriminate between these two possibilities for ULXs in regions of young stellar populations. Thermal-timescale mass transfer generally produces stable disks and persistent X-ray emission. In contrast, mass transfer from massive stars to black holes produces unstable disks and thus transient behavior, provided that the black hole mass exceeds some minimum value. This minimum mass depends primarily on the donor mass and evolutionary state. We show that it exceeds 50 solar masses for a large fraction (greater than 90%) of the mass-transfer lifetime for the most likely donors in young clusters. Thus if long-term monitoring reveals a large transient fraction among ULXs in a young stellar population, these systems would be good candidates for intermediate-mass black holes in a statistical sense; information about the donor star is needed to make this identification secure in any individual case. A transient ULX population would imply a much larger population of quiescent systems of the same type.

description: We have computed the deflection angles caused by 195 objects in the solar system, including 177 satellites and eight asteroids. Twenty-one satellites and six asteroids can bend light from distant compact extragalactic sources by more than 0.1 $μ$as, and fourteen satellites and the asteroid Ceres can deflect light by more than 1.0 $μ$as. We calculated the zones and durations of perturbations posed by the gravitational fields of five planets (excluding Earth, Jupiter, and Saturn), Pluto, and Ceres, where the perturbations would affect astrometry measured with the Squared Kilometre Array (SKA). Perturbed zones with deflection angles larger than 0.1 and 1.0 $μ$as appear as ribbons. Their widths range from dozens of degrees for Uranus, Neptune, and Venus to several degrees or less for other objects at 0.1 $μ$as, and from $\sim$ 16$^{\circ}$ for Venus to several degrees or less for other objects at 1.0 $μ$as. From the calculated perturbation durations, the influence of the gravitational fields of selected objects can be divided into four levels: hardly affect SKA astrometry (I), may have little effect (II), may have a great effect (III) on single-epoch astrometry, and may greatly affect both single- and multi-epoch astrometry (IV). The objects corresponding to these levels are Ceres (I), Pluto (II), Mercury and Mars (III), and other objects (IV).

description: This document presents the strategic goals and operational communication objectives for the period 2024-2028. It is intended as a 5-year rolling plan, to be revised each year by the Communication unit in concert with the EPOS ERIC Executive Director and the EPOS ERIC Executive Coordination Office, and provides an operational guidance to all communication activities carried out by EPOS. Because of the networked and distributed nature of EPOS, the engagement and participation of the EPOS community, and in particular of people in charge of communication and training in the Thematic Core Services and National Research Infrastructures are paramount for the success of the plan: for this reason, the Communication unit will take care of carrying out periodic consultations to improve and update the specific actions envisaged in the plan.
The normal-to-planar superfluid transition in Helium 3

description: We study the nature of the Helium-3 superfluid transition from the normal to the planar phase, which is expected to be stabilized by the dipolar interactions. We determine the RG flow of the corresponding Landau-Ginzburg-Wilson theory by exploiting two fixed-dimension perturbative schemes: the massive zero-momentum scheme and the minimal-subtraction scheme without $ε$ expansion. The analysis of the corresponding six-loop and five-loop series shows the presence of a stable fixed point in the relevant coupling region. Therefore, we predict the transition to be continuous. We also compute critical exponents. The specific-heat exponent $α$ is estimated as $α= 0.20(15)$, while the magnetic susceptibility and magnetization exponents $γ_H$ and $β_H$ for Helium 3 are $γ_H = -0.34(5)$, $β_H = 1.07(9)$.

description: A measurement of strange baryon and antibaryon production in Pb-Pb collisions has been carried out by the NA57 experiment at the CERN SPS, with 40 and 158 A GeV/c beam momentum. Results on $Λ$, $Ξ$ and $Ω$ hyperon yields at mid-rapidity in the most central 53% of Pb-Pb collisions at 40 A GeV/c are presented and compared with those obtained at higher energy, in the same collision centrality range. The $Λ$ and $Ξ^-$ yields per unit rapidity stay roughly constant while those of $Ω^-$, $\barΛ$, $\barΞ^+$ and $\barΩ^+$ increase when going to the higher SPS energy. Hyperon yields at the SPS are compared with those from the STAR experiment in $\sqrt{s_{NN}}$ = 130 GeV Au-Au collisions at RHIC.

Seeing the trees for the carbon: agroforestry for development and carbon mitigation
Creators: name: Anderson, Emily K.
name: Zerriffi, Hisham
Publisher: name: SpringerLink
Year: 2012

description: Land-use, land-use change and forestry (LULUCF) activities will play an important role in global climate change mitigation. Many carbon schemes require the delivery of both climate and rural development benefits by mitigation activities conducted in developing countries. Agroforestry is a LULUCF activity that is gaining attention because of its potential to deliver climate benefits as well as rural development benefits to smallholders. There is hope that agroforestry can deliver co-benefits for climate and development; however experience with early projects suggests co-benefits are difficult to achieve in practice. We review the literature on agroforestry, participatory rural development, tree-based carbon projects and co-benefit carbon projects to look at how recommended project characteristics align when trying to generate different types of benefits. We conclude that there is considerable tension inherent in designing co-benefit smallholder agroforestry projects. We suggest that designing projects to seek ancillary benefits rather than co-benefits may help to reduce this tension.
