description: We examine the problem tidally-induced mass loss from collisionless systems such as dark matter haloes. We develop a model for tidal mass loss, based upon the phase space distribution of particles, which accounts for how both tidal and Coriolis torques perturb the angular momentum of each particle in the system. This allows us to study how both the density profile and velocity anisotropy affect the degree of mass loss--we present basic results from such a study. Our model predicts that mass loss is a continuous process even in a static tidal field, a consequence of the fact that mass loss weakens the potential of the system making it easier for further mass loss to occur. We compare the predictions of our model with N-body simulations of idealized systems in order to check its validity. We find reasonable agreement with the N-body simulations except for in the case of very strong tidal fields, where our results suggest that a higher-order perturbation analysis may be required. The continuous tidally-induced mass loss predicted by our model can lead to substantial reduction in satellite mass in cases where the traditional treatment predicts no mass loss. As such, our results may have important consequences for the orbits and survival of low mass satellites in dark matter haloes.

Devenir Dame : Le livre de la cité des dames
Creators: name: Thibert, Christine
Publisher: name: University of British Columbia
Year: 2010

description: En faisant une analyse du féminisme du Livre de la Cité des Dames, ce travail tente d'élaborer un processus que j'appelle le devenir Dame. La construction de la Cité et l'écriture du Livre se font à travers l'édifIcation de ce processus à trois niveaux : intellectuel, corporel et spirituel. Le but du travail est de montrer comment la lectrice du Livre de la Cité des Dames fait l'expérience de ce processus et devient Dame elle-même en lisant le livre, comme "Christine" le devient en l'écrivant. Il s'agit d'examiner la mise en scène du processus de devenir Dame par l'auteure et de voir comment cela permet à la lectrice de le vivre. Cette approche nous permet d’analyser les aspects plus ou moins problématiques du féminisme pizanien soulevés par plusieurs critiques. Parmi d'autres, il y a la problématique du christianisme. Quoique cela se présente comme un obstacle et empêche plusieurs critiques d'accepter Christine de Pizan en tant que féministe, ce travail affirme que c'est précisément cela qui manifeste le génie (féministe) du Livre de la Cite des Dames. Christine de Pizan, écrivaine d'origine italienne, a écrit Le Livre de la Cite de Dames en 1404-5. En 1405 elle a écrit, comme suite à La Cite des Dames, Le Livre des Trois Vertus ou Le Trésor de la Cité des Dames. Le Livre de la Cité des Dames est une oeuvre allégorique qui s'inspire du fameux De Claris mulieribus (Des dames de renom, 1360) de Boccace et de La Cite de Dieu (413-424) de Saint Augustin. C'est aussi une réfutation de certains auteurs misogynes, comme Matheole et Jean de Meun. Les deux seules éditions critiques faites à partir des manuscrits originaux n'ont pas encore été publiées. Ce sont des thèses de doctorat (Lange, 1974, Hamburg; Curnow, 1975, Vanderbilt). Le livre a été traduit en plusieurs langues : en flamand (1475) et en anglais (1521). Plus récemment, il a été traduit et publié en anglais moderne (Richards, 1982), en allemand (Zimmerman, 1986) et en français moderne (Hicks et Moreau, 1986). Cette dernière traduction, basée sur les manuscrits originaux de Paris, sera utilisée dans ce travail, puisqu'elle est la plus accessible au niveau de la langue et de la publication.

description: We analyse the stellar populations of 75 red-sequence dwarf galaxies in the Coma cluster, based on high signal-to-noise spectroscopy from the 6.5m MMT. The sample covers a luminosity range 3-4 magnitudes below M*, in the cluster core and in a field centred 1 deg to the south-west. We find a strong dependence of the absorption line strengths with location in the cluster. Galaxies further from the cluster centre have stronger Balmer lines than inner-field galaxies of the same luminosity. The magnesium lines are weaker at large radius, while the iron lines are not correlated with radius. Converting the line strengths into estimates of stellar age, metallicity and abundance ratios, we find the gradients are driven by variations in age (>6 sigma significance) and in the iron abundance Fe/H (~2.7 sigma significance). The light element (Mg, C, N, Ca) abundances are almost independent of radius. At radius of 0.4-1.3 degree (~0.3-1.0x the virial radius), dwarf galaxies have ages ~3.8 Gyr on average, compared to ~6 Gyr near the cluster centre. The outer dwarfs are also ~50% more iron-enriched, at given luminosity. Our results confirm earlier indications that the ages of red-sequence galaxies depend on location within clusters, and in Coma in particular. The exceptionally strong trends found here suggest that dwarf galaxies are especially susceptible to environmental "quenching", and/or that the south-west part of Coma is a particularly clear example of recent quenching in an infalling subcluster.

description: The differential cross-section in squared momentum transfer of $ρ$, $ρ^0$, $ω$, $ϕ$, $f_{0}(980)$, $f_{1}(1285)$, $f_{0}(1370)$, $f_{1}(1420)$, $f_{0}(1500)$, and $J/ψ$ produced in high energy virtual photon-proton ($γ$$^{*} p$), photon-proton ($γp$), and proton-proton ($pp$) collisions measured by the H1, ZEUS, and WA102 Collaborations are analyzed by the Monte Carlo calculations. In the calculations, the Erlang distribution, Tsallis distribution, and Hagedorn function are separately used to describe the transverse momentum spectra of the emitted particles. Our results show that the initial- and final-state temperatures increase from lower squared photon virtuality to higher one, and decrease with increasing of center-of-mass energy.

The Fate of Discs around Massive Stars in Young Clusters

description: AIMS: The aim of this work is to understand whether there is a difference in the dispersion of discs around stars in high-density young stellar clusters like the Orion Nebula Cluster (ONC) according to the mass of the star. METHODS: Two types of simulations were combined -- N-body simulations of the dynamics of the stars in the ONC and mass loss results from simulations of star-disc encounters, where the disc mass loss of all stars is determined as a function of time. RESULTS: We find that in the Trapezium, the discs around high-mass stars are dispersed much more quickly and to a larger degree by their gravitational interaction than for intermediate-mass stars. This is consistent with the very recent observations of IC 348, where a higher disc frequency was found around solar mass stars than for more massive stars, suggesting that this might be a general trend in large young stellar clusters.

description: This research aims to explore the intersection between the digital economy and sustainability through a qualitative study that highlights the opportunities and challenges inherent in this convergence. The central issue of this study is to understand how the integration of digital technologies can be optimized to maximize social inclusion benefits while minimizing negative externalities, such as the production of e-waste.

Through semi-structured interviews with key players in the digital sector, non-profit organizations, and social enterprises engaged in digital inclusion and e-waste management, this research seeks to identify innovative practices, challenges encountered and potential solutions to strengthen a sustainable digital economy. The sample is made up of six participants selected by method of convenience, reflecting various profiles involved in the digital economy and sustainability. The expected results aim to provide theoretical and practical recommendations for the development of policies and practices that support a transition towards a more inclusive and environmentally-friendly digital economy. This study contributes to the understanding of the complex interactions between the digital economy, social inclusion and environmental challenges, and proposes avenues for a more sustainable management of digital resources.

description: We study the potential of gravitational wave astronomy to observe the quantum aspects of black holes. According to Bekenstein's quantization, we find that black hole area discretization can have observable imprints on the gravitational wave signal from an inspiraling binary black hole. We study the impact of quantization on tidal heating. We model the absorption lines and compute gravitational wave flux due to tidal heating in such a case. By including the quantization we find the dephasing of the gravitational wave, to our knowledge it has never been done before. We discuss the observability of the phenomena in different parameter ranges of the binary. We show that in the inspiral, it leads to vanishing tidal heating for the high spin values. Therefore measuring non-zero tidal heating can rule out area quantization. We also argue that if area quantization is present in nature then our current modeling with reflectivity can possibly probe the Hawking radiation which may bring important information regarding the quantum nature of gravity.

description: In two dimensions the non-interacting density of states displays a Van Hove singularity (VHS) which introduces an intrinsic electron-hole asymmetry, absent in three dimensions. We show that due to this VHS the strong-coupling analysis of tunneling spectra in high-$T_c$ superconductors must be reconsidered. Based on a microscopic model which reproduces the experimental data with great accuracy, we elucidate the peculiar role played by the VHS in shaping the tunneling spectra, and show that more conventional analyses of strong-coupling effects can lead to severe errors.

Este estudo exploratório-descritivo, utilizando-se da pesquisa bibliográfica e documental para caracterizar o surgimento e a expansão da oferta de ensino superior e das universidades no Brasil, contextualizando a origem dessas instituições na Europa e nas Américas, bemcomo o surgimento e a expansão de universidades e outras instituições de ensino superior no Estado da Bahia. Os resultados evidenciam uma inserção extremamente tardia das universidades no país, apesar do histórico de ensino superior datado do Brasil Colônia, em um cenário de resistências à criação dessas instituições até o ano de 1920, com a criação da Universidade do Rio de Janeiro. Os resultados evidenciam também um atraso histórico na oferta federal no Estado da Bahia, que se limitou a capital, entre os anos de 1946 a 2002, com a presença da Universidade Federal da Bahia (UFBA). Além disso, demonstram a iniciativa estratégica de interiorização com criação do sistema estadual baiano de educação superior, formado por quatro universidades estaduais, a partir da década de 1970 (com surgimento da Universidade Estadual de Feira de Santana, a primeira). Demonstram ainda que, nos últimos anos, houve significativa expansão da oferta pela iniciativa privada no país, a partir do período de ditadura militar, sendo bem mais lenta no setor público, que apesar disso, implantou novas universidades federais no interior do Estado baiano.

description: Microresonator-based platforms with $χ^{(2)}$ nonlinearities have the potential to perform frequency conversion at high efficiencies and ultralow powers with small footprints. The standard doctrine for achieving high conversion efficiency in cavity-based devices requires "perfect matching", that is, zero phase mismatch while all relevant frequencies are precisely at a cavity resonance, which is difficult to achieve in integrated platforms due to fabrication errors and limited tunabilities. In this Letter, we show that the violation of perfect matching does not necessitate a reduction in conversion efficiency. On the contrary, in many cases, mismatches should be intentionally introduced to improve the efficiency or tunability of conversion. We identify the universal conditions for maximizing the efficiency of cavity-based frequency conversion and show a straightforward approach to fully compensate for parasitic processes such as thermorefractive and photorefractive effects that, typically, can limit the conversion efficiency. We also show rigorously that these high-efficiency states are stable.

description: We report on temporal and spectral study of a flat spectrum radio quasar, PKS B1222+216, in flare state to get insight into acceleration and emission mechanisms inside the jet. This is one of the brightest and highly active blazar in the MeV-GeV regime. Long term multi-waveband light curves of this object showed a flaring activity in 2014 with two distinct flares. Work presented here includes the study of flux-index variation, flare fitting, hardness ratio and spectral modelling of both X-ray and $γ-$ray data. The flux-index correlation we have found in MeV-GeV regime indicates a 'softer when brighter' feature. Modelling of $γ-$ray light curves suggests that low energy particles initiate both the flares followed by the injection of high energy particles. The short rise time indicates the presence of Fermi first order acceleration. Multi-waveband spectral energy distributions (SEDs) generated for flares are fitted with a single-zone leptonic model. This SED modelling shows the inverse Compton scattering of photon field reprocessed from Broad Line Region (BLR) primarily accounts for GeV emission. We have also report a shift in break-energy in the soft X-ray regime during the flaring activity which is the consequence of a rapid change in injection spectra.

description: In this paper, we try to reveal the structure of the $Y(4660)$ from the light-quark perspective. We study the dipion invariant mass spectrum and the helicity angular distributions of the $e^+ e^- \to Y(4660) \to ψ(2S) π^+π^-$ process. In particular, we consider the effects of different light-quark SU(3) eigenstates inside the $Y(4660)$. The strong pion-pion final-state interactions as well as the $K\bar{K}$ coupled channel in the $S$-wave are taken into account model independently by using dispersion theory. We find that the light-quark SU(3) octet state plays a significant role in this transition, implying that the $Y(4660)$ contains a large light-quark component and thus might not be a pure conventional charmonium state. In the fit scheme considering both the SU(3) singlet and SU(3) octet states, two solutions are found, and both solutions reproduce the $ππ$ invariant mass spectra well. New measurement data with higher statistics in the future will be helpful to better distinguish these two solutions.

description: Gravitational microlensing has become a mature technique for discovering small gravitational lenses in the Universe which are otherwise beyond our detection limits. Similarly, plasma microlensing can help us explore cosmic plasma lenses. Both pulsar scintillation and extreme scattering events of compact radio sources suggest the existence of $\sim$ AU scale plasma lenses in the ionized interstellar medium (IISM), whose astrophysical correspondence remains a mystery. We demonstrate that plasma microlensing events by these plasma lenses recorded in the form of wide-band dynamic spectra are a powerful probe of their nature. Using the recently developed Picard-Lefschetz integrator for the Kirchhoff-Fresnel integral, we simulate such dynamic spectra for a well-motivated family of single-variable plasma lenses. We demonstrate that the size, strength, and shape of the plasma lens can be measured from the location of the cusp point and the shape of spectral caustics respectively, with a combination of distances and the effective velocity known a priori or measured from the widths of the interference pattern. Future wide-band observations of pulsars, whose plasma microlensing events may be predictable from parabolic arc monitoring, are the most promising ground to apply our results for a deeper insight into the fine structures in the IISM.

description: Results of forward modelling of acoustic wave propagation in a realistic solar sub-photosphere with two cases of steady horizontal flows are presented and analysed by the means of local helioseismology. The simulations are based on fully compressible ideal hydrodynamical modelling in a Cartesian grid. The initial model is characterised by solar density and pressure stratifications taken from the standard Model S and is adjusted in order to suppress convective instability. Acoustic waves are excited by a non-harmonic source located below the depth corresponding to the visible surface of the Sun. Numerical experiments with coherent horizontal flows of linear and Gaussian dependences of flow speed on depth are carried out. These flow fields may mimic horizontal motions of plasma surrounding a sunspot, differential rotation or meridional circulation. An inversion of the velocity profiles from the simulated travel time differences is carried out. The inversion is based on the ray approximation. The results of inversion are then compared with the original velocity profiles. The influence of steady flow on the propagation of sound waves through the solar interior is analysed. Further, we propose a method of obtaining the travel-time differences for the waves propagating in sub-photospheric solar regions with horizontal flows. The method employs directly the difference between travel-time diagrams of waves propagating with and against the background flow. The analysis shows that the flow speed profiles obtained from inversion based on the ray approximation differ from the original ones. The difference between them is caused by the fact that the wave packets propagate along the ray bundle, which has a finite extent, and thus reach deeper regions of the sub-photosphere in comparison with ray theory.

description: Quantum sensors offer the capability to reach unprecedented precision by operating at the standard quantum limit (SQL) or beyond by using quantum entanglement. But an emerging class of quantum sensors that use Rydberg electromagnetically-induced transparency (EIT) to detect rf electric fields have yet to reach the SQL. In this work we prove that this discrepancy is due to fundamental limitations in the EIT probing mechanism. We derive the optimum sensitivity of a three-level quantum sensor based on EIT, or more generally coherent spectroscopy, and compare this to the SQL. We apply a minimal set of assumptions, while allowing strong probing fields, thermal broadening, and large optical depth. We derive the optimal laser intensities and optical depth, providing specific guidelines for sensitive operation under common experimental conditions. Clear boundaries of performance are established, revealing that ladder-EIT can not achieve the SQL due to unavoidable absorption loss. The results may be applied to any EIT-based quantum sensor, but we particularly emphasize our results' importance to the growing field of Rydberg quantum sensing.

description: Manual fits to spectral times series of Type Ia supernovae have provided a method of reconstructing the explosion from a parametric model but due to lack of information about model uncertainties or parameter degeneracies direct comparison between theory and observation is difficult. In order to mitigate this important problem we present a new way to probabilistically reconstruct the outer ejecta of the normal Type Ia supernova SN 2002bo. A single epoch spectrum, taken 10 days before maximum light, is fit by a 13-parameter model describing the elemental composition of the ejecta and the explosion physics (density, temperature, velocity, and explosion epoch). Model evaluation is performed through the application of a novel rapid spectral synthesis technique in which the radiative transfer code, TARDIS, is accelerated by a machine-learning framework. Analysis of the posterior distribution reveals a complex and degenerate parameter space and allows direct comparison to various hydrodynamic models. Our analysis favors detonation over deflagration scenarios and we find that our technique offers a novel way to compare simulation to observation.

Quasiparticle bands in cuprates by quantum chemical methods: towards an ab initio description of strong electron correlations

description: Realistic electronic-structure calculations for correlated Mott insulators are notoriously hard. Here we present an ab initio multiconfiguration scheme that adequately describes strong correlation effects involving Cu 3d and O 2p electrons in layered cuprates. In particular, the O 2p states giving rise to the Zhang-Rice band are explicitly considered. Renormalization effects due to nonlocal spin interactions are also treated consistently. We show that the dispersion of the lowest band observed in photoemission is reproduced with quantitative accuracy. Additionally, the evolution of the Fermi surface with doping follows directly from our ab initio data. Our results thus open a new avenue for the first-principles investigation of the electronic structure of correlated Mott insulators.
Prompt production of the hidden charm pentaquarks in the LHC

description: Motivated by the observation of the first hidden charm pentaquarks by the LHCb collaboration in 2015 and the updated analysis with an order-of-magnitude larger data set in 2019, we estimate their cross sections for the prompt production as well as their heavy quark spin partners, in the $Σ_c^{(*)}\bar{D}^{(*)}$ hadronic molecular picture, at the center-of-mass energy $7~\mathrm{TeV}$ in the $pp$ collision. Their cross sections are several $\mathrm{nb}$ and we would expect several tens hidden charm pentaquark events in the LHC based on its current integrated luminosity. The cross sections show a sizable deviation of the cross sections for hidden charm pentaquarks with the third isospin component $I_z=+\frac{1}{2}$ ($P_c^+$) from those with $I_z=-\frac{1}{2}$ ($P_c^0$). The cross sections decrease dramatically with the increasing transverse momentum. Our study can also tell where to search for the missing hidden charm pentaquarks. The confirmation of the complete hidden charm pentaquarks in the heavy quark symmetry would further verify their $Σ_c^{(*)}\bar{D}^{(*)}$ molecular interpretation. In addition, the relative strength among these cross sections for pentaquarks can help us to identify the quantum numbers of the $P_c(4440)$ and $P_c(4457)$.

description: The motion of submerged magnetic microspheres rolling at a glass-water interface has been studied using magnetic rotation and optical tweezers combined with bright-field microscopy particle tracking techniques. Individual microspheres of varying surface roughness were magnetically rotated both in and out of an optical trap to induce rolling, along either plain glass cover slides or glass cover slides functionalized with polyethylene glycol. It has been observed that the manipulated microspheres exhibited nonlinear dynamic rolling-while-slipping motion characterized by two motional regimes: At low rotational frequencies, the speed of microspheres free-rolling along the surface increased proportionately with magnetic rotation rate; however, a further increase in the rotation frequency beyond a certain threshold revealed a sharp transition to a motion in which the microspheres slipped with respect to the external magnetic field resulting in decreased rolling speeds. The effects of surface-microsphere interactions on the position of this threshold frequency are posed and investigated. Similar experiments with microspheres rolling while slipping in an optical trap showed congruent results.

description: We study the quantum-classical correspondence of an experimentally accessible system of interacting bosons in a tilted triple-well potential. With the semiclassical analysis, we get a better understanding of the different phases of the quantum system and how they could be used for quantum information science. In the integrable limits, our analysis of the stationary points of the semiclassical Hamiltonian reveals critical points associated with second-order quantum phase transitions. In the nonintegrable domain, the system exhibits crossovers. Depending on the parameters and quantities, the quantum-classical correspondence holds for very few bosons. In some parameter regions, the ground state is robust (highly sensitive) to changes in the interaction strength (tilt amplitude), which may be of use for quantum information protocols (quantum sensing).
