description: The inner slope (gammadm) of the dark matter (DM) density profile of cosmological halos carries information about the properties of DM and/or baryonic processes affecting the halo gravitational potential. Cold DM cosmological simulations predict steep inner slopes, gammadm~1. We test this prediction on the MACS J1206.2-0847 cluster at redshift z=0.44, whose DM density profile was claimed to be cored at the center. We determine the cluster DM density profile from 2 kpc from the cluster center to the virial radius (~2 Mpc), using the velocity distribution of ~500 cluster galaxies and the internal velocity dispersion profile of the Brightest Cluster Galaxy (BCG), obtained from VIMOS@VLT and MUSE@VLT data. We solve the Jeans equation of dynamical equilibrium using an upgraded version of the MAMPOSSt method. The total mass profile is modeled as a sum of a generalized-NFW profile that describes the DM component, allowing for a free inner slope of the density profile, a Jaffe profile that describes the BCG stellar mass component, and a non-parametric baryonic profile that describes the sum of the remaining galaxy stellar mass and of the hot intra-cluster gas mass. Our total mass profile is in remarkable agreement with independent determinations based on X-ray observations and strong lensing. We find gammadm=0.7 (-0.1 +0.2) (68\% confidence levels), consistent with predictions from recent LambdaCDM cosmological numerical simulations.

description: The essay examines the influence of Guittone’s poetry on Petrarch’s Canzoniere. The ordering and historical-biographical contextualization of Guittone’s political songs in the Laurentian codex can be related to the choices that in Canzoniere allow the integration of the three political songs into the love story. The influence of Guittone’s poetry is also evident in other poems, especially in the so-called canzone-frottola.
Multi-TeV dark matter density in the inner Milky Way halo: spectral and dynamical constraints

description: We develop a comprehensive study of the gamma-ray flux observed by H.E.S.S. in 5 regions of the Galactic Center (GC). Motivated by previous works on a possible Dark Matter (DM) explanation for the TeV cut-off observed in the innermost $\sim 16$ pc of the Galaxy, we aim to constrain the DM density profile up to a radius $\sim 450$ pc from the GC. In this region, cosmological simulations and Galactic dynamics studies fail to produce a strong prediction of the DM profile. With our proof-of-concept analysis, we set upper limits on the density distribution of thermal multi-TeV WIMPs, compatible with the observed gamma-ray flux. The results agree with the hypothesis of a DM density enhancement in the GC with respect to the benchmark NFW profile ($γ=1$) and allow us to exclude profiles with a slope $γ\gtrsim 1.3$. We also investigate the possibility that such an enhancement could be related to the existence of a DM spike associated with the supermassive black hole Sgr A*. We find out that the existence of an adiabatic DM spike smoothed by the scattering off of WIMPs by the bulge stars may be consistent with the observed gamma-ray flux if the spike forms on an underlying generalized NFW profile with $γ\lesssim 0.8$, corresponding to a spike slope $γ_{sp-star}= 1.5$ and radius $R_\text{sp-stars} \sim 25$-$30$ pc. Instead, in the extreme case of the instantaneous growth of the black hole, the profile could have up to $γ\sim 1.2$, a corresponding $γ_{sp-inst}=1.4$ and $R_\text{sp-inst}\sim 15$-$25$ pc. Moreover, the results of our analysis of the total DM mass enclosed within the S2 orbit are less stringent than the spectral analysis. Our work aims to guide future studies of the GC region, with both current and next-generation telescopes, like the next Cherenkov Telescope Array, that will be able to scan the GC with improved flux sensitivity and angular resolution.

Plasma medicine
FAIR Data
Knowledge Graph
Blockchain

description: We propose a management infrastructure for research data specially designed for plasma medicine and adjacent fields (low temperature plasma science). Systematically archiving and publishing data has become an increasingly important part of research. This often follows the idea of FAIR (Findable, Accessible, Interoperable, and Reusable) data [1]. We currently build a system that accompanies the researcher from planning the experiment through its execution to saving, publishing, and reusing of the originating data with meaningful metadata. The goal is to use a knowledge graph that the community of plasma scientists continuously augments and maintains. This knowledge graph is used to help researchers in finding the metadata that is necessary for each individual experiment. It will also be linked to knowledge graphs of other fields to increase interoperability across different fields of research and therefore the visibility of plasma research. This gives credit to the multitude of research methods used in this field. The knowledge graph provides options to define quality criteria, which ensure the findability and reusability of published data.
 As a first step towards this goal, we developed the data platform INPTDAT (https://www.inptdat.de/) to upload research data in a structure that is adapted to plasma research data. This structure follows the general plasma metadata schema, Plasma-MDS, which has been published recently [2] (see Fig. 1). Data published on INPTDAT and described by using Plasma-MDS can easily be found and cited by the owner as well as other researchers using its unique DOI (digital object identifier).
 The use of blockchain technology is another part of the intended infrastructure to make the publishing and citing of data safer and traceable. In the future, this system can also allow reputation monitoring.
 Together, these systems will support data exchange and thus enhance data-driven science in plasma medicine and beyond.

ancient heritage

description: If transdisciplinary databases can still be considered a novelty in many corners of the Humanities overall, they can especially be seen as such for most fields focused on the study of the ancient world. With digital research products increasingly becoming the norm, we are well-advised to consider early on just how we are preserving ancient cultural heritage and in what ways we are making it accessible to both specialist researchers and the wider public. Research groups setting out to compile and establish datasets with the intention of providing them open access are quickly confronted with a reality that they can at least partially anticipate, more often than not finding themselves insufficiently equipped, both in terms of funding long-term (especially beyond the deadline of their project) and of digital humanities knowhow or experience. In particular, while moving away from internal, isolated repositories to highly interconnected resources crossing traditional boundaries, new issues of standardization, metadata philosophies, linking and attribution are meshed together with familiar problems of provenance, citation and authorship. This brief overview takes a look at the current state of the art in antiquity-focused online resources for textual material, and some approaches already being taken that show potential in the long term, such as embracing educational aspects and increasing the autonomy of users by harnessing their curiosity. Asking the central questions of what kinds of data we are collecting, and how we are choosing to preserve and present it, this talk will place the spotlight on transdisciplinary platforms (e.g. papyri.info, Trismegistos) and promising project-based, often topic-focused endeavors (e.g. Kyprianos, 4CARE, Grammateus) harnessing the digital in a public-facing fashion.

description: The Fermi observations of GRB 110721A (Axelsson et al. 2012) have revealed an unusually high peak energy ~ 15 MeV in the first time bin of the prompt emission. We find that an interpretation is unlikely in terms of internal shock models, and confirm that a standard black-body photospheric model also falls short. We show that dissipative photospheric synchrotron models ranging from extreme magnetically dominated to baryon dominated dynamics, on the other hand, are able to accommodate such high peak values.

description: Antiferromagnetic $\mathrm{L1_2}$-$\mathrm{Mn_3Ir}$ combines outstanding spin-transport properties with magnons in the terahertz (THz) frequency range. However, the THz radiation emitted by ultrafast spin-to-charge conversion via the inverse spin Hall effect remains unexplored. In this study, we measured the THz emission and transmission of a permalloy/(111)-oriented $\mathrm{L1_2}$-$\mathrm{Mn_3Ir}$ multilayer by THz time-domain spectroscopy. The spin Hall angle was determined to be approximately constant at 0.035 within a frequency range of 0.3-2.2 THz, in comparison with the THz spectroscopy of a permalloy/Pt multilayer. Our results not only demonstrate the potential of $\mathrm{L1_2}$-$\mathrm{Mn_3Ir}$ as a spintronic THz emitter but also provide insights into the THz spin transport properties of $\mathrm{L1_2}$-$\mathrm{Mn_3Ir}$.

title: A Comparison of Text-Driven and Coursebook Materials: Investigating their Potential Learning Effects on EFL Learners’ Perceptions and Communicative Performance Using Multiple Research Methods
Creators: name: Aldhahri, Eman Saleh
Publisher: name: University of Liverpool Repository
Year: 2024

description: This study compared the potential effects of Text-Driven (TD) and Coursebook (CB) materials
on learners' perceptions and interactions in EFL classrooms. It also explored which teaching
materials are more likely to facilitate learners’ communicative competence through theoretical
and empirical evaluations.
82 EFL female students at A2 (CEFR) level were selected in this study from the English
Language Institute (ELI) at the University of Jeddah in KSA and divided into two comparable
intact classes taught by the researcher. The first group was taught the developed Text-Driven
materials, whereas the second group was taught the Coursebook materials. The study adopted
a multiple-method research design. Data were collected through six methods: questionnaires,
individual interviews, classroom interaction analysis, teachers’ observations, virtual forums,
and pre-post communicative tests.
The data revealed that while both TD and CB materials were viewed positively by the
participants, Text-Driven showed a number of advantages over coursebook materials in
developing learners’ engagement and classroom interactions. The findings demonstrated that
the frequencies of learners' turns using L1 or L2 are higher in the TD group than in CB and that
the observed interactional patterns differ considerably among the groups. The TD interactional
patterns involved more open than closed responses, and their interaction was meaningful,
personally engaging, and focused on both content and forms compared to their counterpart.
Similarly, the two ELI instructors who observed the researcher’s TD and CB video-recoded
classes commented that TD materials seemed more effective than the CB in developing
classroom interaction, resulting in meaningful interactional patterns among TD learners. The
pre-post communicative test results supported the previous data and showed that the TD
materials are more likely to accelerate the learners’ overall English “communicative
competence” than the CB materials. The theoretical content analysis of the coursebook unit
provided further evidence that most of the tasks are controlled and aimed at practising language
points and thus may not facilitate L2 communicative competence.
The findings of this study would benefit TESOL/Applied linguistics stakeholders as a flexible
communicative teaching model was proposed. It reflects the findings of language learning
studies that explore how second language competence can be developed. Furthermore, these
iii
results may assist the ELI and other contexts in considering the significance of L2 materials
development and its potential impact on learners’ engagement and communicative
performance. In light of these findings, several recommendations are proposed.
Dimensionality effects in the LDOS of ferromagnetic hosts probed via STM: spin-polarized quantum beats and spin filtering

description: We theoretically investigate the local density of states (LDOS) probed by a STM tip of ferromagnetic metals hosting a single adatom and a subsurface impurity. We model the system via the two-impurity Anderson Hamiltonian. By using the equation of motion with the relevant Green functions, we derive analytical expressions for the LDOS of two host types: a surface and a quantum wire. The LDOS reveals Friedel-like oscillations and Fano interference as a function of the STM tip position. These oscillations strongly depend on the host dimension. Interestingly, we find that the spin-dependent Fermi wave numbers of the hosts give rise to spin-polarized quantum beats in the LDOS. While the LDOS for the metallic surface shows a damped beating pattern, it exhibits an opposite behavior in the quantum wire. Due to this absence of damping, the wire operates as a spatially resolved spin filter with a high efficiency.

title: Narrative-Driven Fluctuations in Sentiment: Evidence Linking Traditional and Social Media
Creators: name: Macaulay, Alistair
name: Song, Wenting
Publisher: name: Bank of Canada
Year: 2023

description: This paper studies the role of narratives for macroeconomic fluctuations. We micro-found narratives as directed acyclic graphs and show how exposure to different narratives can affect expectations in an otherwise standard macroeconomic model. We capture such competing narratives in news media’s reports on a US yield curve inversion by using techniques in natural language processing. Linking these media narratives to social media data, we show that exposure to a recessionary narrative is associated with a more pessimistic sentiment, while exposure to a nonrecessionary narrative implies no such change in sentiment. In a model with financial frictions, narrative-driven beliefs create a trade-off for quantitative easing: extended periods of quantitative easing make narrative-driven waves of pessimism more frequent, but smaller in magnitude.
description: Cette étude s’intéresse au rôle des récits médiatiques dans les fluctuations macroéconomiques. Nous micro-fondons les récits sous la forme de graphes acycliques dirigés et montrons comment l’exposition à différents discours peut influer sur les attentes dans un modèle macroéconomique par ailleurs standard. Nous documentons, à l’aide de techniques de traitement du langage naturel, de tels récits divergents publiés par les médias qui portent sur une inversion de la courbe de rendement aux États-Unis. En reliant ces récits à des données tirées des médias sociaux, nous montrons que l’exposition à un discours récessionniste est associée à davantage de pessimisme, alors que l’exposition à un discours non récessionniste n’a pas d’effet sur l’opinion. Dans un modèle incorporant des frictions financières, les croyances influencées par un récit créent un arbitrage pour ce qui est de l’assouplissement quantitatif. En effet, des périodes prolongées d’assouplissement accroissent la fréquence des vagues de pessimisme générées par le narratif, mais réduisent leur ampleur.

description: We obtain stability criteria for diffusive inviscid multicomponent Israel-Stewart hydrodynamics with and without background or dynamic electromagnetic fields. Our analysis is grounded on the maximum entropy principle, and it provides stability conditions that are valid around all thermodynamic equilibria, including rotating equilibria, charged equilibria, and equilibria in a background gravitational field. We prove that the electromagnetic part of the information current is stable and causal by construction and, therefore, the stability criteria found for Israel-Stewart theories of hydrodynamics automatically extend to similar formulations of magnetohydrodynamics.

description: Context. Phase-mask coronagraphy is advantageous in terms of inner working angle and discovery space. It is however still plagued by drawbacks such as sensitivity to tip-tilt errors and chromatism. A nulling stellar coronagraph based on the adaptive phase-mask concept using polarization interferometry is presented in this paper. Aims. Our concept aims at dynamically and achromatically optimizing the nulling efficiency of the coronagraph, making it more immune to fast low-order aberrations (tip-tilt errors, focus, ...). Methods. We performed numerical simulations to demonstrate the value of the proposed method. The active control system will correct for the detrimental effects of image instabilities on the destructive interference. The mask adaptability both in size, phase and amplitude also compensates for manufacturing errors of the mask itself, and potentially for chromatic effects. Liquid-crystal properties are used to provide variable transmission of an annulus around the phase mask, but also to achieve the achromatic π phase shift in the core of the PSF by rotating the polarization by 180 degrees. Results. We developed a new concept and showed its practical advantages using numerical simulations. This new adaptive implementation of the phase-mask coronagraph could advantageously be used on current and next-generation adaptive optics systems, enabling small inner working angles without compromising contrast.

In this note we discuss how hypercontractive inequalities, in various settings, can be used to obtain (fairly) concise proofs of several results in quantum information theory: a recent lower bound of Lancien and Winter on the bias achievable by local measurements which are 4-designs; spectral concentration bounds for k-local Hamiltonians; and a recent result of Pellegrino and Seoane-Sepulveda giving general lower bounds on the classical bias obtainable in multiplayer XOR games.

description: Surface gravity plays a pivotal role in the characterization of black holes and also in formulating the laws of black hole thermodynamics. Despite its significance, defining surface gravity in general spacetimes is a nontrivial task and thus has multiple definitions that lack equivalence in dynamical scenarios. This paper reviews different notions of dynamical surface gravity and then proposes a new definition based on tidal acceleration, which is an alternative way of characterizing spacetime curvature. By integrating tidal acceleration from the horizon to infinity, we could retrieve surface gravity in familiar situations of Schwarzschild and Kerr spacetimes. We outline a generic procedure for calculating surface gravity and substantiate our proposal by investigating the surface gravity of stationary spacetimes and reproducing the results from the literature. Furthermore, we examine surface gravity in nonstationary spacetimes, with a focus on Vaidya spacetime as a model of evaporating black holes.

description: The flexibility of common generalized gradient approximation for the exchange-correlation energy is investigated by monitoring the equilibrium volume of transition metals. It is shown that no universal gradient-level approximation yielding consistent errors for all metals exists. Based on an element-specific optimization, the concept of quasi-non-local gradient-level approximation is introduced. The strength of the scheme is demonstrated on several transition metal alloys.

description: Key Messages •The total value of food imports in Malawi has more than doubled over the last two decades. •Cereals, animal and vegetable fats, and oils dominate Malawi’s food imports. •Much of the food import portfolio is for direct consumption as opposed to producing value-added products. •The increase in food imports is driven by low agricultural productivity, rising demand for processed foods, and low domestic industrial sector competitiveness. •Unregulated food imports from the neighboring countries present unfair competition to formally imported food products and negatively impact growth of domestic food industries. •Policy reforms to minimize reliance on food imports could focus on increasing agricultural productivity; improving competitiveness of local agri-food industries; investing in agri-food processing; promoting locally produced products; and curbing unregulated food importation.
Integrable vortex-type equations on the two-sphere

description: We consider the Yang-Mills instanton equations on the four-dimensional manifold S^2xSigma, where Sigma is a compact Riemann surface of genus g>1 or its covering space H^2=SU(1,1)/U(1). Introducing a natural ansatz for the gauge potential, we reduce the instanton equations on S^2xSigma to vortex-type equations on the sphere S^2. It is shown that when the scalar curvature of the manifold S^2xSigma vanishes, the vortex-type equations are integrable, i.e. can be obtained as compatibility conditions of two linear equations (Lax pair) which are written down explicitly. Thus, the standard methods of integrable systems can be applied for constructing their solutions. However, even if the scalar curvature of S^2xSigma does not vanish, the vortex equations are well defined and have solutions for any values of the topological charge N. We show that any solution to the vortex equations on S^2 with a fixed topological charge N corresponds to a Yang-Mills instanton on S^2xSigma of charge (g-1)N.

description: We study the meson spectrum of the ${\cal{N}}=4$ supersymmetric Yang-Mills theory with ${\cal{N}}=2$ fundamental hypermultiplets for a finite electric field by using the D3/D7 model. The spectrum for scalar and vector mesons is computed by analyzing the (quasi-)normal modes for the fluctuations of the D7-brane embedding and gauge fields. In the presence of an electric field, two different phases in the background are realized: the meson and dissociation phases. In this paper, we analyze the meson spectrum of scalar and vector mesons for all ranges of the electric field and explore the effect of the electric field on the meson spectrum, that is, the Stark effect. In the meson spectrum, we observe the avoided crossing between different levels due to the coupling of fluctuations via the electric field.

description: Distributed estimation of the average value over a Wireless Sensor Network has recently received a lot of attention. Most papers consider single variable sensors and communications with feedback (e.g. peer-to-peer communications). However, in order to use efficiently the broadcast nature of the wireless channel, communications without feedback are advocated. To ensure the convergence in this feedback-free case, the recently-introduced Sum-Weight-like algorithms which rely on two variables at each sensor are a promising solution. In this paper, the convergence towards the consensus over the average of the initial values is analyzed in depth. Furthermore, it is shown that the squared error decreases exponentially with the time. In addition, a powerful algorithm relying on the Sum-Weight structure and taking into account the broadcast nature of the channel is proposed.

description: We introduce CartiMorph, a framework for automated knee articular cartilage morphometrics. It takes an image as input and generates quantitative metrics for cartilage subregions, including the percentage of full-thickness cartilage loss (FCL), mean thickness, surface area, and volume. CartiMorph leverages the power of deep learning models for hierarchical image feature representation. Deep learning models were trained and validated for tissue segmentation, template construction, and template-to-image registration. We established methods for surface-normal-based cartilage thickness mapping, FCL estimation, and rule-based cartilage parcellation. Our cartilage thickness map showed less error in thin and peripheral regions. We evaluated the effectiveness of the adopted segmentation model by comparing the quantitative metrics obtained from model segmentation and those from manual segmentation. The root-mean-squared deviation of the FCL measurements was less than 8%, and strong correlations were observed for the mean thickness (Pearson's correlation coefficient $ρ\in [0.82,0.97]$), surface area ($ρ\in [0.82,0.98]$) and volume ($ρ\in [0.89,0.98]$) measurements. We compared our FCL measurements with those from a previous study and found that our measurements deviated less from the ground truths. We observed superior performance of the proposed rule-based cartilage parcellation method compared with the atlas-based approach. CartiMorph has the potential to promote imaging biomarkers discovery for knee osteoarthritis.
