Gamma-ray flares in the Crab Nebula: A case of relativistic reconnection?

description: The Crab Nebula was formed after the collapse of a massive star about a thousand years ago, leaving behind a pulsar that inflates a bubble of ultra-relativistic electron-positron pairs permeated with magnetic field. The observation of brief but bright flares of energetic gamma rays suggests that pairs are accelerated to PeV energies within a few days; such rapid acceleration cannot be driven by shocks. Here, it is argued that the flares may be the smoking gun of magnetic dissipation in the Nebula. Using 2D and 3D particle-in-cell simulations, it is shown that the observations are consistent with relativistic magnetic reconnection, where pairs are subject to strong radiative cooling. The Crab flares may highlight the importance of relativistic magnetic reconnection in astrophysical sources.

Global simulations of magnetorotational turbulence II: turbulent energetics
Creators: name: Parkin, E. R.
Publisher: name: arXiv
Year: 2013
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: Magnetorotational turbulence draws its energy from gravity and ultimately releases it via dissipation. However, the quantitative details of this energy flow have not been assessed for global disk models. In this work we examine the energetics of a well-resolved, three-dimensional, global magnetohydrodynamic accretion disk simulation by evaluating statistically-averaged mean-field equations for magnetic, kinetic, and internal energy using simulation data. The results reveal that turbulent magnetic (kinetic) energy is primarily injected by the correlation between Maxwell (Reynolds) stresses and shear in the (almost Keplerian) mean flow, and removed by dissipation. This finding differs from previous work using local (shearing-box) models, which indicated that turbulent kinetic energy was primarily sourced from the magnetic energy reservoir. Lorentz forces provide the bridge between the magnetic and kinetic energy reservoirs, converting ~ 1/5 of the total turbulent magnetic power input into turbulent kinetic energy. The turbulent energies (both magnetic and kinetic) are mainly driven by terms associated with the turbulent fields, with only a minor influence from mean magnetic fields. The interaction between mean and turbulent fields is most evident in the induction equation, with the mean radial magnetic field being strongly influenced by the turbulent electromotive force (EMF). During the quasi-steady turbulent state roughly 2/3 of the Poynting flux travels into the corona, with the remainder transporting magnetic energy in the radial direction. In contrast to previous studies, the stress-related part of the Poynting flux is found to dominate, which may have important implications for "reflection" models of Seyfert galaxy coronae that typically invoke a picture of buoyant rising of magnetic flux tubes via advection.

Identifiability of small rank tensors and related problems
Creators: name: Santarsiero, Pierpaola
Publisher: name: Universit� degli studi di Trento
Year: 2022

description: In this thesis we work on problems related to tensor decomposition from a geometrical perspective. In the first part of the thesis we focus on the identifiability problem, which amounts to understand in how many ways a tensor can be decomposed as a minimal sum of elementary tensors. In particular we completely classify the identifiability of any tensor up to rank 3. In the second part of the thesis we continue to work with specific elementsand we introduce the notion of r-thTerracini locus of a Segre variety. This is the locus containing all points for which the differential of the map between the r-th abstarct secant variety and the r-th secant variety of a Segre variety drops rank. We completely determine the r-th Terracini locus of any Segre variety in the case of r = 2, 3.

Counter Narrative Generation for Fighting Online Hate Speech
Creators: name: Chung, Yi-ling
Publisher: name: Universit� degli studi di Trento
Year: 2022

description: Studies on online hate speech have mostly focused on the automated detection of harmful messages. Still, tackling hate speech in the standard way of content moderation may be charged with censorship and overblocking. One alternate strategy, that has received little attention so far, is to directly intervene in the discussion with counter narratives (i.e., textual responses meant to withstand hatred and prevent its spreading). While recent advances in NLP can help in automatizing counter narrative generation by using pre-trained language models, challenges such as lack of high-quality data, generic generation, hallucination and multilinguality must be addressed. This dissertation focuses on automatic and effective hate mitigation targeting Islamophobia by data collection and counter narrative generation. Firstly, we tackle the problem of data scarcity. We present CONAN, the first large-scale and expert-based hate countering dataset for English, Italian and French. Then, we present an author-reviewer approach that can create automatically high-quality data while reducing human effort. Secondly, we develop models to generate counter narratives focusing on informative and multilingual responses. We introduce a knowledge-driven pipeline that can produce suitable and informative English counter narratives while avoiding hallucination phenomena. We address multilinguality by presenting approaches to counter narrative generation for Italian, and characterizing the effect of data size and of data quality on model performance. Thirdly, we present an extensive evaluation of automatic counter narrative generation embedded in a platform that NGO operators can use to monitor social media data and counter hate speech. Results show an increased efficiency and effectiveness of operators' activities. We conclude by discussing our contributions and future research directions on building models for hate countering.

description: Topological phases in frustrated quantum spin systems have fascinated researchers for decades. One of the earliest proposals for such a phase was the chiral spin liquid put forward by Kalmeyer and Laughlin in 1987 as the bosonic analogue of the fractional quantum Hall effect. Elusive for many years, recent times have finally seen a number of models that realize this phase. However, these models are somewhat artificial and unlikely to be found in realistic materials. Here, we take an important step towards the goal of finding a chiral spin liquid in nature by examining a physically motivated model for a Mott insulator on the Kagome lattice with broken time-reversal symmetry. We first provide a theoretical justification for the emergent chiral spin liquid phase in terms of a network model perspective. We then present an unambiguous numerical identification and characterization of the universal topological properties of the phase, including ground state degeneracy, edge physics, and anyonic bulk excitations, by using a variety of powerful numerical probes, including the entanglement spectrum and modular transformations.

description: INTRODUCTION: In South Africa, evidence shows high HIV prevalence in older populations, with sexual behavior consistent with high HIV acquisition and transmission risk. However, there is a dearth of evidence on older people's HIV incidence. METHODS: We used a 2010-2011 cohort of HIV-negative adults in rural South Africa who were 40 years or older at retest in 2015-2016 to estimate HIV incidence over a 5-year period. We used Poisson regression to measure the association of HIV seroconversion with demographic and behavioral covariates. We used inverse probability sampling weights to adjust for nonresponse in 2015, based on a logistic regression with predictors of sex and age group at August 2010. RESULTS: HIV prevalence increased from 21% at baseline to 23% in the follow-up survey. From a cohort of 1360 individuals, 33 seroconverted from HIV negative at baseline, giving an overall HIV incidence rate of 0.39 per 100 person-years [95% confidence interval (CI): 0.28 to 0.57]. The rate for women was 0.44 (95% CI: 0.30 to 0.67), double than that for men, 0.21 (95% CI: 0.10 to 0.51). Incidence rate ratios (IRRs) again show women's risk of seroconverting double than that of men (IRR = 2.04, P value = 0.098). In past age 60, the IRR of seroconversion was significantly lower than that for those in their 40s (60-69, IRR = 0.09, P value = 0.002; 70-79, IRR = 0.14, P value = 0.010). CONCLUSIONS: The risk of acquiring HIV is not zero for people older than 50 years, especially women. Our findings highlight the importance of acknowledging that older people are at high risk of HIV infection and that HIV prevention and treatment campaigns must take them into consideration.

Hindu women devotees and menstrual taboos: gender, agency and religion in the case of the Sabarimala temple
Creators: name: Joseph, Phebyn
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: Sabarimala temple, located in the south Indian state of Kerala, banned menstruating women from entering its premises from the onset of their menarche until the time they reached menopause. While the majority of Hindu temples across India restrict women’s entry while they are menstruating, the Sabarimala temple prohibits women’s entry during their entire menstruating lifecycle, i.e., between the ages of ten and fifty years. The temple authorities and devotees justify this restriction as part of the diverse Hindu customs and traditional religious beliefs. Liberal media and secular feminists however, argue that the age-old custom of banning women from the temple is a violation of women’s rights and freedom of religious expressions. Many Hindu women devotees insist on supporting the religious injunction despite the lifting of the Sabarimala temple ban by the Indian Supreme Court in 2018. My thesis discusses the response of the Hindu women devotees who uphold the customs of the temple and support the prohibition on the entry of menstruating women. I first discuss the menstrual taboo discourse as a patriarchal construct, as analysed by Western feminist theorists. I argue that the complex notion of religious women’s agency can be understood in a more nuanced manner by being critical of the Western knowledge system, and examining how knowledge is produced and transmitted in its specific cultural context. Located in the intersection between decolonisation theories and feminist theories, my research is grounded on ethnographic interviews and Saba Mahmood’s notion of ‘agency’ to deconstruct the attitude of the Hindu women devotees, especially towards a ritual that prohibits them from expressing their religiosity.
Fermi-Pasta-Ulam model with long-range interactions: Dynamics and thermostatistics

description: We introduce and numerically study a long-range-interaction generalization of the one-dimensional Fermi-Pasta-Ulam (FPU) $β-$ model. The standard quartic interaction is generalized through a coupling constant that decays as $1/r^α$ ($α\ge 0$)(with strength characterized by $b>0$). In the $α\to\infty$ limit we recover the original FPU model. Through classical molecular dynamics computations we show that (i) For $α\geq 1$ the maximal Lyapunov exponent remains finite and positive for increasing number of oscillators $N$ (thus yielding ergodicity), whereas, for $0 \le α<1$, it asymptotically decreases as $N^{- κ(α)}$ (consistent with violation of ergodicity); (ii) The distribution of time-averaged velocities is Maxwellian for $α$ large enough, whereas it is well approached by a $q$-Gaussian, with the index $q(α)$ monotonically decreasing from about 1.5 to 1 (Gaussian) when $α$ increases from zero to close to one. For $α$ small enough, the whole picture is consistent with a crossover at time $t_c$ from $q$-statistics to Boltzmann-Gibbs (BG) thermostatistics. More precisely, we construct a "phase diagram" for the system in which this crossover occurs through a frontier of the form $1/N \propto b^δ/t_c^γ$ with $γ>0$ and $δ>0$, in such a way that the $q=1$ ($q>1$) behavior dominates in the $\lim_{N \to\infty} \lim_{t \to\infty}$ ordering ($\lim_{t \to\infty} \lim_{N \to\infty}$ ordering).

description: We calculate the increase in the number of modes (the Kac number) per unit length and the change in the zero-point energy (the Casimir energy) of the electromagnetic field resulting from the introduction of a thin perfectly conducting cylindrical shell of elliptical cross-section. Along the way we give a novel route to the calculation of these physical quantities. The Casimir energy is found to be attractive with the circular case corresponding to the energy maximum and the large eccentricity limit being the divergent energy minimum. As a result, with only Casimir stresses present, a fixed area shell is unstable with respect to collapse onto itself. This instability is argued to persist at arbitrary temperature.

Mapping the psychedelic bubble

Subjects: subject: Medicine and Health Sciences

description: Hallucinogens are heavily promoted as “game changers” for the treatment of various psychiatric diseases. However, those psychedelics have known safety issues that are linked with effects such as hallucinations, paranoia, and mood changes. Therefore, these drugs should be carefully evaluated in studies. In a series of 12 news stories by Nature, an article on psilocybin for pain relief notes that researchers are trying to avoid repeating the mistakes that contributed to the opioid crisis. There are strong parallels: prescription of psychedelics and of opioids is rising as a result of aggressive marketing, whereas the evidence for effectiveness comes mostly from small, short-term trials involving highly selected patients in secure settings, without adequate comparators. And attention to safety issues such as tolerance and drug dependence is crucial, particularly over the long term. The US Food and Drug Administration has designated many psychedelics as a “breakthrough therapy”, thus lowering the bar for approval. Esketamine, for example, was controversially approved for treatment-resistant depression without adequate monitoring to assess its long-term harm-to-benefit ratio.

description: We establish a duality between massive fermions coupled to topologically massive gravity (TGM) in $d=3$ space-time dimensions and a purely gravity theory which also will turn out to be a TGM theory but with different parameters: the original graviton mass in the TGM theory coupled to fermions picks-up a contribution from fermion bosonization. We obtain explicit bosonization rules for the fermionic currents and for the energy-momentum-tensor showing that the identifications do not depend explicitly on the parameters of the theory. These results are the gravitational analog of the results for $2+1$ Abelian and non-Abelian bosonization in flat space-time.

description: The correlation between the invisible Higgs branching ratio ($B_h^{\rm inv} $) vs. dark matter (DM) direct detection ($σ_p^{\rm SI}$) in Higgs portal DM models is usually presented in the effective field theory (EFT) framework. This is fine for singlet scalar DM, but not in the singlet fermion DM (SFDM) or vector DM (VDM) models. In this paper, we derive the explicit expressions for this correlation within UV completions of SFDM and VDM models with Higgs portals, and discuss the limitation of the EFT approach. We show that there are at least two additional hidden parameter in $σ_p^{\rm SI}$ in the UV completions: the singlet-like scalar mass $m_2$ and its mixing angle $α$ with the SM Higgs boson ($h$). In particular, if the singlet-like scalar is lighter than the SM Higgs boson ($m_2 < m_h \cos α/ \sqrt{1 + \cos^2 α}$), the collider bound becomes weaker than the one based on EFT.

description: Background: More than 80,000 dengue cases including 215 deaths were reported nationally in less than 7 months between 2016 and 2017, a fourfold increase in the number of reported cases compared to the average number over 2010–2016. The region of Negombo, located in the Western province, experienced the greatest number of dengue cases in the country and is the focus area of our study, where we aim to capture the spatial-temporal dynamics of dengue transmission. Methods: We present a statistical modeling framework to evaluate the spatial-temporal dynamics of the 2016–2017 dengue outbreak in the Negombo region of Sri Lanka as a function of human mobility, land-use, and climate patterns. The analysis was conducted at a 1 km × 1 km spatial resolution and a weekly temporal resolution. Results: Our results indicate human mobility to be a stronger indicator for local outbreak clusters than land-use or climate variables. The minimum daily temperature was identified as the most influential climate variable on dengue cases in the region; while among the set of land-use patterns considered, urban areas were found to be most prone to dengue outbreak, followed by areas with stagnant water and then coastal areas. The results are shown to be robust across spatial resolutions. Conclusions: Our study highlights the potential value of using travel data to target vector control within a region. In addition to illustrating the relative relationship between various potential risk factors for dengue outbreaks, the results of our study can be used to inform where and when new cases of dengue are likely to occur within a region, and thus help more effectively and innovatively, plan for disease surveillance and vector control.

description: The equivariant version of semiprojectivity was recently introduced by the first author. We study properties of this notion, in particular its relation to ordinary semiprojectivity of the crossed product and of the algebra itself. We show that equivariant semiprojectivity is preserved when the action is restricted to a cocompact subgroup. Thus, if a second countable compact group acts semiprojectively on a C*-algebra $A$, then $A$ must be semiprojective. This fails for noncompact groups: we construct a semiprojective action of the integers on a nonsemiprojective C*-algebra. We also study equivariant projectivity and obtain analogous results, however with fewer restrictions on the subgroup. For example, if a discrete group acts projectively on a C*-algebra $A$, then $A$ must be projective. This is in contrast to the semiprojective case. We show that the crossed product by a semiprojective action of a finite group on a unital C*-algebra is a semiprojective C*-algebra. We give examples to show that this does not generalize to all compact groups.

description: Consider a system of \(n\) players in which each initially starts on a different team. At each time step, we select an individual winner and an individual loser randomly and the loser joins the winner's team. The resulting Markov chain and stochastic matrix clearly have one absorbing state, in which all players are on the same team, but the combinatorics along the way are surprisingly elegant. The expected number of time steps until each team is eliminated is a ratio of binomial coefficients. When a team is eliminated, the probabilities that the players are configured in various partitions of \(n\) into \(t\) teams are given by multinomial coefficients. The expected value of the time to absorbtion is \((n-1)^2\) steps. The results depend on elementary combinatorics, linear algebra, and the theory of Markov chains.

description: Nuclear collective motion provides valuable constraint on the size of neutron-skin thickness and the properties of nuclear matter symmetry energy. By employing relativistic nuclear energy density functional (RNEDF) and covariance analysis related to $χ^2$ fitting of the model parameters, relevant observables are identified for dipole excitations, which strongly correlate with the neutron-skin thickness $(r_{np})$, symmetry energy at saturation density $(J)$ and slope of the symmetry energy $(L)$. Using the RNEDF framework and experimental data on pygmy dipole strength ($^{68}$Ni, $^{132}$Sn, $^{208}$Pb) and dipole polarizability ($^{208}$Pb), it is shown how the values of $J$, and $L$, and $r_{np}$ are constrained. The isotopic dependence of moments associated to dipole excitations in $^{116-136}$Sn shows that the low-energy dipole strength and polarizability in neutron-rich nuclei display strong sensitivity to the symmetry energy parameter $J$, more pronounced than in isotopes with moderate neutron-to-proton number ratios.

Spinach-derived porous carbon nanosheets as high-performance catalysts for oxygen reduction reaction

description: Biomass-derived porous carbon materials are effective electrocatalysts for oxygen reduction reaction (ORR), with promising applications in low-temperature fuel cells and metal–air batteries. Herein, we developed a synthesis procedure that used spinach as a source of carbon, iron, and nitrogen for preparing porous carbon nanosheets and studied their ORR catalytic performance. These carbon sheets showed a very high ORR activity with a half-wave potential of +0.88 V in 0.1 M KOH, which is 20 mV more positive than that of commercial Pt/C catalysts. In addition, they showed a much better long-term stability than Pt/C and were insensitive to methanol. The remarkable ORR performance was attributed to the accessible high-density active sites that are primarily from Fe–Nx moieties. This work paves the way toward the use of metal-enriching plants as a source for preparing porous carbon materials for electrochemical energy conversion and storage applications.
RIFLESSIONI PER UNA EVENTUALE RICERCA SULLA GENERALIZZABILITA' DEL CONCETTO DI COSTO TOTALE

description: Riprendendo il modello classico di costo totale, come pure la relativa analisi del punto di pareggio, si esamina la possibilità di generalizzare un tale concetto anche al fine della pianificazione del business. L'esame di casi con diversi valori di costi fissi e variabili, attraverso la presa in considerazione di variazioni della produzione, mette in evidenza concetti utili a valutare la flessibilità produttiva, in parte anche ai fini di maggior resilienza per variazioni indotte dal mercato. La tentata analisi dei "Costi come Vettori del Valore posti in una Matrice", appare foriera di aprire nuovi tipi di relazioni in una matrice di business planning, la cui pratica validità è tutta da indagare. Il tentativo di generalizzazione, per diverse ragioni, ma sostanzialmente per la "volatilità" che affligge sempre in misura più ampia, imprevedibile ed inaspettata le metodologie di valutazione, pianificazione e controllo del costo totale, indica necessaria una ben più ampia riflessione e investigazione sugli approcci tradizionali. Ciò può aprire una possibile e ben più strutturata ricerca di concreti sistemi generali, utili agli obiettivi del Total Cost Management, tenendo in conto l'opportunità di affrontare la "volatilità" ben oltre le logiche di contingecies, coperture assicurative o finanza derivata.

description: Direct detection of dark matter with directional sensitivity offers not only measurement of both recoil energy and direction of dark matter, but also a way to understand dark matter distribution in the Galaxy. Maxwell distribution is usually supposed as the distribution near the Earth, however, deviation from that, caused by tidal streams in the Galaxy, has been suggested. We explore the possibility of distinguishing the distribution by direct detection using nuclear emulsions.

description: We present an overview of the GW SAID group effort to analyze on new pion photoproduction on both proton- and neutron-targets. The main database contribution came from the recent CLAS and MAMI unpolarized and polarized measurements. The differential cross section for the processes gamma n --> pi- p was extracted from new measurements accounting for Fermi motion effects in the impulse approximation (IA) as well as NN and piN effects beyond the IA. The EM coupling results are compared to other recent studies.

description: In many recommendation applications such as news recommendation, the items that can be rec- ommended come and go at a very fast pace. This is a challenge for recommender systems (RS) to face this setting. Online learning algorithms seem to be the most straight forward solution. The contextual bandit framework was introduced for that very purpose. In general the evaluation of a RS is a critical issue. Live evaluation is of- ten avoided due to the potential loss of revenue, hence the need for offline evaluation methods. Two options are available. Model based meth- ods are biased by nature and are thus difficult to trust when used alone. Data driven methods are therefore what we consider here. Evaluat- ing online learning algorithms with past data is not simple but some methods exist in the litera- ture. Nonetheless their accuracy is not satisfac- tory mainly due to their mechanism of data re- jection that only allow the exploitation of a small fraction of the data. We precisely address this issue in this paper. After highlighting the limita- tions of the previous methods, we present a new method, based on bootstrapping techniques. This new method comes with two important improve- ments: it is much more accurate and it provides a measure of quality of its estimation. The latter is a highly desirable property in order to minimize the risks entailed by putting online a RS for the first time. We provide both theoretical and ex- perimental proofs of its superiority compared to state-of-the-art methods, as well as an analysis of the convergence of the measure of quality.
An open framework for infinite walking with saccadic redirection

description: In this project we created an expandable framework for allowing infinite walking in virtual reality in a closed play area. A saccade is a rapid eye movement with a unique property: the eye temporarily gathers reduced information - saccadic suppression. We leverage the suppression to redirect the user's walking towards the center of the play area by rotating the virtual world around the camera's location. With the VR environment and corresponding pre and post experience questions we could already show an improvement in understanding on a set of participants. Modern VR hardware such as the Vive Eye Pro allows a reasonable sample rate of eye movement measurements. A self-developed VR testing environment was used and with corresponding pre and post experience questions we tested a group of participants regarding general motion and VR- sickness parameters. We found a certain angle for the maximum saccade rotation which was base of further testing. We found, that our framework and the default settings successfully allow saccadic redirection with only marginal discomfort for the users.

Hyperfine structure in $^{229g}$Th$^{3+}$ as a probe of the $^{229g}$Th $\rightarrow$ $^{229m}$Th nuclear excitation energy

description: We identify a potential means to extract the $^{229g}$Th $\rightarrow$ $^{229m}$Th nuclear excitation energy from precision microwave spectroscopy of the $5F_{5/2,7/2}$ hyperfine manifolds in the ion $^{229g}$Th$^{3+}$. The hyperfine interaction mixes this ground fine structure doublet with states of the nuclear isomer, introducing small but observable shifts to the hyperfine sub-levels. We demonstrate how accurate atomic structure calculations may be combined with measurement of the hyperfine intervals to quantify the effects of this mixing. Further knowledge of the magnetic dipole decay rate of the isomer, as recently reported, allows an indirect determination of the nuclear excitation energy.
