description: We calculate, for the first time, differential distributions for double $ρ^0$ meson production in exclusive ultraperipheral, ultrarelativistic collisions via a double scattering mechanism. The calculations are done in impact parameter space. The cross section for $γA \to ρ^0 A$ is parametrized based on an existing calculation. Smearing of $ρ^0$ masses is taken into account. The results of our calculations are compared at the RHIC energy to the contribution of the two-photon mechanism discussed previously in the literature. The cross section for the double scattering mechanism is found to be an order of magnitude larger at $M_{ρρ} $ 3 GeV, than that for the photon-photon mechanism. Compared to the two-photon mechanism the double scattering mechanism populates somewhat larger $ρ^0 ρ^0$ invariant masses and larger rapidity distances between the two $ρ^0$ mesons and gives a significant contribution to the $A A \to A A π^+ π^- π^+ π^-$ reaction. Some observables related to charged pions are presented too. We compare the results of our calculation with the STAR collaboration results on four charged pion production. While the shape in invariant mass of the four-pion system is very similar to the measured one, the predicted cross section constitutes only 20% of the measured one. We discuss a possibility of identifying the double scattering mechanism at the LHC.

description: Media and popular culture have long played a significant role in forming perceptions of and social attitudes about race, including the differences between Black, Indigenous, Asian, Latinx, and White American family culture and structure. This has led to the historical portrayal of minority families, especially Black families, as poor and dysfunctional. Over time, the American media and entertainment industry has become more inclusive. Recent shifts in technology have accelerated the democratization of media production and cultural commentary, increasing the availability of opportunities for Black people within the entertainment industry. 

 In the status quo, major networks, independent media companies, and individual creators simultaneously contribute to the ever-expanding volume of Black American media, visual art, and popular culture. Black media and popular culture comprise a variety of genres and innovative multimedia formats including but not limited to web series, music videos, movies, television series, and short films. The increasing prevalence of Black media and cultural productions has led to a more diverse representation of Black family structures and social identities within the Black community. Black artists, critics, and creators are producing work that reflects a beautiful mosaic of perspectives on the Black living experience and the universal human condition.

Black American media has become (hyper)visible in American culture and across the world. This allows for unprecedented social discourse on identity politics and political discourse on Black social issues in government, academia, and beyond. Contemporary Black media engages in critical conversations about a range of intersectional issues of race, gender, class, and disability including sexuality, religiosity, addiction, mental health, and more. Despite the growing volume of Black media and improved media representation within the United States, certain Black characters, figures, films, and series maintain reliance on stereotypes and archetypes. This increases the importance of robust and nuanced engagement in terms of media commentary, analysis of the media production process, and consideration of additional other issues such as economic conditions or socio-political factors that influence media and popular culture.

description: In a context of widespread border checks and border closures, the circulation of workers was not totally abolished: some workers, whose mobility was considered necessary, continued to benefit from free movement. The selection of the types of work mobility to be preserved, in the crisis, is the starting point of this contribution. After considering the most obvious, a "restrictive selection", the Insight suggests that selection can also constitute a way to encourage mobility, in the Union interest, and examines why "selective mobility" can strengthen free movement.

description: Machine learning models that convert user-written text descriptions into images are now widely available online and used by millions of users to generate millions of images a day. We investigate the potential for these models to amplify dangerous and complex stereotypes. We find a broad range of ordinary prompts produce stereotypes, including prompts simply mentioning traits, descriptors, occupations, or objects. For example, we find cases of prompting for basic traits or social roles resulting in images reinforcing whiteness as ideal, prompting for occupations resulting in amplification of racial and gender disparities, and prompting for objects resulting in reification of American norms. Stereotypes are present regardless of whether prompts explicitly mention identity and demographic language or avoid such language. Moreover, stereotypes persist despite mitigation strategies; neither user attempts to counter stereotypes by requesting images with specific counter-stereotypes nor institutional attempts to add system ``guardrails'' have prevented the perpetuation of stereotypes. Our analysis justifies concerns regarding the impacts of today's models, presenting striking exemplars, and connecting these findings with deep insights into harms drawn from social scientific and humanist disciplines. This work contributes to the effort to shed light on the uniquely complex biases in language-vision models and demonstrates the ways that the mass deployment of text-to-image generation models results in mass dissemination of stereotypes and resulting harms.

description: We present initial results from the Jubilee ISW project, which models the expected \LambdaCDM Integrated Sachs-Wolfe (ISW) effect in the Jubilee simulation. The simulation volume is (6 Gpc/h)^3, allowing power on very large-scales to be incorporated into the calculation. Haloes are resolved down to a mass of 1.5x10^12 M_sun/h, which allows us to derive a catalogue of mock Luminous Red Galaxies (LRGs) for cross-correlation analysis with the ISW signal. We find the ISW effect observed on a projected sky to grow stronger at late times with the evolution of the ISW power spectrum matching expectations from linear theory. Maps of the gravitational lensing effect, including the convergence and deflection fields, are calculated using the same potential as for the ISW. We calculate the redshift dependence of the ISW-LRG cross-correlation signal for a full sky survey with no noise considerations. For l < 30, the signal is strongest for lower redshift bins (z ~ 0.2 to 0.5), whereas for l > 30 the signal is best observed with surveys covering z ~ 0.6-1.0.

Three-dimensional interface modelling with two-dimensional seismic data: the Alpine crust–mantle boundary

description: We present a new approach to determine the 3-D topography and lateral continuity of seismic interfaces using 2-D-derived controlled-source seismic reflector data. The aim of the approach is to give the simplest possible structure consistent with all reflector data and error estimates. We define simplicity of seismic interfaces by the degree of interface continuity (i.e. shortest length of offsets) and by the degree of interface roughness (least surface roughness). The method is applied to structural information of the crust–mantle boundary (Moho) obtained from over 250 controlled-source seismic reflection and refraction profiles in the greater Alpine region. The reflected and refracted phases from the Moho interface and their interpretation regarding crustal thickness are reviewed and their reliability weighted. Weights assigned to each reflector element are transformed to depth errors considering Fresnel volumes. The 2-D-derived reflector elements are relocated in space (3-D migration) and interpolation is performed between the observed reflector elements to obtain continuity of model parameters. Interface offsets are introduced only where required according to the principle of simplicity. The resulting 3-D model of the Alpine crust–mantle boundary shows two offsets that divide the interface into a European, an Adriatic and a Ligurian Moho, with the European Moho subducting below the Adriatic Moho, and with the Adriatic Moho underthrusting the Ligurian Moho. Each sub-interface depicts the smoothest possible (i.e. simplest) surface, fitting the reflector data within their assigned errors. The results are consistent with previous studies for those regions with dense and reliable controlled-source seismic data. The newly derived Alpine Moho interface, however, surpasses earlier studies by its lateral extent over an area of about 600 km by 600 km, by quantifying reliability estimates along the interface, and by obeying the principle of being consistently as simple as possible.

description: Fluid jets are found in nature at all length scales, from microscopic to cosmological. Here we report on an electroosmotically driven jet from a single glass nanopore about 75 nm in radius with a maximum flow rate ~15 pL/s. A novel anemometry technique allows us to map out the vorticity and velocity fields that show excellent agreement with the classical Landau-Squire solution of the Navier Stokes equations for a point jet. We observe a phenomenon that we call flow rectification: an asymmetry in the flow rate with respect to voltage reversal. Such a nanojet could potentially find applications in micromanipulation, nanopatterning, and as a diode in microfluidic circuits.

description: La question « en quoi tel logiciel permet-il efficacement d’apprendre ? » se pose de plus en plus fréquemment avec l’offre croissante de logiciels éducatifs associés à des environnements informatiques pour l’apprentissage humain en évolution constante. Nous avons évalué un logiciel gratuit et disponible sur Internet nommé iconomix. Créé et actualisé en permanence par la Banque nationale suisse, il est destiné à l’enseignement de l’économie pour les élèves en formation postobligatoire de degré 2 (gymnases et écoles professionnelles). Dans ce mémoire, nous proposons une démarche débutant par la présentation du concept iconomix, de son propriétaire-éditeur, et de l’information qu’il fournit dans son module “Challenge en ligne sur la finance” aux enseignants. Nous comparons les contenus d’enseignements offerts avec les requis du plan d’études d’une classe d’élèves gestionnaires du commerce de détail de 1è année à l’école professionnelle, puis nous analysons le logiciel et ses dimensions (utilité, utilisabilité et acceptabilité) au moyen d’outils spécialisés pour l’évaluation d’environnements informatiques pour l’apprentissage humain. Nous relatons nos observations effectuées en classe sur l'utilisation du logiciel par les élèves, sur le niveau de leur engagement dans la tâche et leur motivation et comportement face à la machine. Enfin, nous émettons une recommandation positive pour l’utilisation d’iconomix avec les élèves, que ce soit en amont de l’enseignement pour faire émerger leurs représentations antérieures, durant les phases d’enseignement comme support de cours complémentaire, ou en guise de révisions avant une évaluation. Le contenu de ce mémoire professionnel fournit des éléments et une méthode qui sont utiles à l’évaluation de logiciels éducatifs destinés à l’enseignement.

description: In X (judgment of 3 March 2020, case C-717/18, X (Mandat d'arrêt européen - Double incrimination), the Court of Justice has clarified the implications of a reform determining the increase of the penalty scales on the lifting the double criminality check pursuant to Art. 2, para. 2, of Framework Decision 2002/584/JHA, where an European Arrest Warrant is pending. While analysing the interpretative approach underpinning the reasoning of both the Court of Justice and the AG, the present Insight focuses on two key issues: the relationship between the EAW system and the nullum crimen, nulla poena sine lege principle, and the renewed importance of the EAW form for purposes of contextual interpretation of the Framework Decision. The concluding remarks provide some reflections on the principle of effectiveness in EAW matters.
Unintended cation crossover influences CO2 reduction selectivity in Cu-based zero-gap electrolysers

description: Membrane electrode assemblies enable CO2 electrolysis at industrially relevant rates, yet their operational stability is often limited by formation of solid precipitates in the cathode pores, triggered by cation crossover from the anolyte due to imperfect ion exclusion by anion exchange membranes. Here we show that anolyte concentration affects the degree of cation movement through the membranes, and this substantially influences the behaviors of copper catalysts in catholyte-free CO2 electrolysers. Systematic variation of the anolyte (KOH or KHCO3) ionic strength produced a distinct switch in selectivity between either predominantly CO or C2+ products (mainly C2H4) which closely correlated with the quantity of alkali metal cation (K+) crossover, suggesting cations play a key role in C-C coupling reaction pathways even in cells without discrete liquid catholytes. Operando X-ray absorption and quasi in situ X-ray photoelectron spectroscopy revealed that the Cu surface speciation showed a strong dependence on the anolyte concentration, wherein dilute anolytes resulted in a mixture of Cu+ and Cu0 surface species, while concentrated anolytes led to exclusively Cu0 under similar testing conditions. These results show that even in catholyte-free cells, cation effects (including unintentional ones) significantly influence reaction pathways, important to consider in future development of catalysts and devices.

description: The Moore-Greitzer partial differential equation (PDE) is a commonly used mathematical model for capturing flow and pressure changes in axial-flow jet engine compressors. Determined by compressor geometry, the deterministic model is characterized by three types of Hopf bifurcations as the throttle coefficient decreases, namely surge (mean flow oscillations), stall (inlet flow disturbances) or a combination of both. Instabilities place fundamental limits on jet-engine operating range and thus limit the design space. In contrast to the deterministic PDEs, the Hopf bifurcation in stochastic PDEs is not well understood. The goal of this particular work is to rigorously develop low-dimensional approximations using a multiscale analysis approach near the deterministic stall bifurcation points in the presence of additive noise acting on the fast modes. We also show that the reduced-dimensional approximations (SDEs) contain multiplicative noise. Instability margins in the presence of uncertainties can be thus approximated, which will eventually lead to lighter and more efficient jet engine design.

description: Entangled photons can be used to make measurements with an accuracy beyond that possible with classical light. While most implementations of quantum metrology have used states made up of a single colour of photons, we show that entangled states of two colours can show supersensitivity to optical phase and path-length by using a photonic crystal fibre source of photon pairs inside an interferometer. This setup is relatively simple and robust to experimental imperfections. We demonstrate sensitivity beyond the standard quantum limit and show super-resolved interference fringes using entangled states of two, four, and six photons.

description: After the various recent crisis - financial, migration, Brexit, to name but a few - the mantra "the end of the EU is nigh" has somewhat become a common place. It is hardly surprising to see this repeated over and over again, while Europe got caught in the COVID-19 whirlwind - or the "eye of the storm" if you prefer more established quotes. Albeit initially a tad bit slow in mobilizing, the EU is producing measures at a competing speed. This short contribution aims at reflecting on the instruments used to achieve all these goals. And, in this regard, the conclusion is foretold, while Europe does indeed what it does best: governing through soft law. A look at selected COVID-19 emergency instruments shows that the salience of both the advantages and the drawbacks of soft law are brought to the fore by this pandemic. The current crisis should be turned into an opportunity for reform.

description: We study correlation functions of two AdS giant gravitons in AdS$_5\times S^5$ and a BPS supergravity mode using holography. In the gauge theory these are described by BPS correlators of Schur polynomials of fully-symmetric representations and a single trace operator. We find full agreement between the semiclassical gravity and gauge theory computations at large $N$, for both diagonal and off-diagonal structure constants. Our analysis in $\mathcal{N}=4$ SYM provides a simpler derivation to the results in the literature, and it can be readily generalized to operators describing bound states of AdS giant gravitons as well as bubbling geometries.

description: Recently, unconventional materials (or obstructed atomic insulators) have attracted much attention owing to the unconventional feature of mismatch between Wannier centers and atomic positions. In this paper, we demonstrate that the trigonal selenium and tellurium host an unconventional nature in both electronic and phonon spectra. In electronic band structures, the band representation (BR) decomposition for occupied bands has to contain the essential BR of $A@3b$, and the real-space invariant is $δ_1@3b=-1$. The $π$ Zak phase suggests that the one-dimensional Se/Te chain is a chiral Su-Schrieffer-Heeger chain. The effective magnetism can be induced by $p$ states at ends. More importantly, a large shift current is obtained in Se quantum well. In addtion, in phonon spectra, three sets of phonon bands are well separated and assigned to $B@3b$, $B@3a$, and $A@3b$ BRs, respectively. Thus, the obstructed phonon states are predicted on the (0001) surface. As the prototypes of unconventional materials in both electronic and phonon spectra, our findings could create much interest in the study of obstructed surface electronic and phonon states in these novel materials.

description: In a recent Article published in this Journal, Gareth Davies draws a parallel between European citizens as fashioned by EU law and pre-war Europe's Jews (G. Davies, How Citizenship Divides: The New Legal Class of Transnational Europeans, in European Papers, Vol. 4, 2019, No 3, www.europeanpapers.eu, p. 675 et seq.). This parallel raises two serious issues. One is the complete lack of contextualisation of such a dubious comparison. The other is the lack of careful methodological engagement with the ways in which EU law operates in actual practice. This note cautions against the use of such parallels and calls for the development of renewed categories to analyse and critically assess the European Union and its law.

description: When Gaussian null coordinates are adapted to a Killing horizon, the near-horizon limit is defined by a coordinate rescaling and then by taking the regulator parameter $\varepsilon$ to be small, as a way of zooming into the horizon hypersurface. In this coordinate setting, it is known that the metric of a non-extremal Killing horizon in the near-horizon limit is divergent, and it has been a common practice to impose extremality in order to set the divergent term to zero. Although the metric is divergent, we show for a class of Killing horizons that the vacuum Einstein's equations can be separated into a divergent and a finite part, leading to a well-defined minimal set of Einstein's equations one needs to solve. We extend the result to Einstein gravity minimally coupled to a massless scalar field. We also discuss the case of Einstein gravity coupled to a Maxwell field, in which case the separability holds if the Maxwell potential has non-vanishing components only in the directions of the horizon spatial cross section.
description: v2: 14 pages, comment added regarding the validity of the result to a class of near-horizon geometries where higher order corrections to equation (1.4) are set to zero. Section 1.3.1 added on applications of the result. Version accepted for publication in Classical and Quantum Gravity

description: Following the experimental realization of Dicke superradiance in Bose gases coupled to cavity light fields, we investigate the behavior of ultra cold fermions in a transversely pumped cavity. We focus on the equilibrium phase diagram of spinless fermions coupled to a single cavity mode and establish a zero temperature transition to a superradiant state. In contrast to the bosonic case, Pauli blocking leads to lattice commensuration effects that influence self-organization in the cavity light field. This includes a sequence of discontinuous transitions with increasing atomic density and tricritical superradiance. We discuss the implications for experiment.

description: We have determined high-resolution hypocenters for 45,000+ earthquakes that occurred between 1980 and 2000 in the Long Valley caldera area using a double-difference earthquake location algorithm and routinely determined arrival times. The locations reveal numerous discrete fault planes in the southern caldera and adjacent Sierra Nevada block (SNB). Intracaldera faults include a series of east/west-striking right-lateral strike-slip faults beneath the caldera's south moat and a series of more northerly striking strike-slip/normal faults beneath the caldera's resurgent dome. Seismicity in the SNB south of the caldera is confined to a crustal block bounded on the west by an east-dipping oblique normal fault and on the east by the Hilton Creek fault. Two NE-striking left-lateral strike-slip faults are responsible for most seismicity within this block. To understand better the stresses driving seismicity, we performed stress inversions using focal mechanisms with 50 or more first motions. This analysis reveals that the least principal stress direction systematically rotates across the studied region, from NE to SW in the caldera's south moat to WNW–ESE in Round Valley, 25 km to the SE. Because WNW–ESE extension is characteristic of the western boundary of the Basin and Range province, caldera area stresses appear to be locally perturbed. This stress perturbation does not seem to result from magma chamber inflation but may be related to the significant (∼20 km) left step in the locus of extension along the Sierra Nevada/Basin and Range province boundary. This implies that regional-scale tectonic processes are driving seismic deformation in the Long Valley caldera.

description: We confirm the planetary nature of Kepler-412b, listed as planet candidate KOI-202 in the Kepler catalog, thanks to our radial velocity follow-up program of Kepler-released planet candidates, which is on going with the SOPHIE spectrograph. We performed a complete analysis of the system by combining the Kepler observations from Q1 to Q15, to ground-based spectroscopic observations that allowed us to derive radial velocity measurements, together with the host star parameters and properties. We also analyzed the light curve to derive the star's rotation period and the phase function of the planet, including the secondary eclipse. We found the planet has a mass of 0.939 $\pm$ 0.085 M$_{Jup}$ and a radius of 1.325 $\pm$ 0.043 R$_{Jup}$ which makes it a member of the bloated giant subgroup. It orbits its G3 V host star in 1.72 days. The system has an isochronal age of 5.1 Gyr, consistent with its moderate stellar activity as observed in the Kepler light curve and the rotation of the star of 17.2 $\pm$ 1.6 days. From the detected secondary, we derived the day side temperature as a function of the geometric albedo and estimated the geometrical albedo, Ag, is in the range 0.094 to 0.013. The measured night side flux corresponds to a night side brightness temperature of 2154 $\pm$ 83 K, much greater than what is expected for a planet with homogeneous heat redistribution. From the comparison to star and planet evolution models, we found that dissipation should operate in the deep interior of the planet. This modeling also shows that despite its inflated radius, the planet presents a noticeable amount of heavy elements, which accounts for a mass fraction of 0.11 $\pm$ 0.04.

description: The identification of tumor-specific biomarkers is one of the bottlenecks in the development of cancer therapies. Previous work revealed altered surface levels of reduced/oxidized cysteines in many cancers due to overexpression of redox-controlling proteins such as protein disulfide isomerases on the cell surface. Alterations in surface thiols can promote cell adhesion and metastasis, making thiols attractive targets for treatment. Few tools are available to study surface thiols on cancer cells and exploit them for theranostics. Here, we describe a nanobody (CB2) that specifically recognizes B cell lymphoma and breast cancer in a thiol-dependent manner. CB2 binding strictly requires the presence of a nonconserved cysteine in the antigen-binding region and correlates with elevated surface levels of free thiols on B cell lymphoma compared to healthy lymphocytes. Nanobody CB2 can induce complement-dependent cytotoxicity against lymphoma cells when functionalized with synthetic rhamnose trimers. Lymphoma cells internalize CB2 via thiol-mediated endocytosis which can be exploited to deliver cytotoxic agents. CB2 internalization combined with functionalization forms the basis for a wide range of diagnostic and therapeutic applications, rendering thiol-reactive nanobodies promising tools for targeting cancer.
Necessary condition for local quantum operations and classical communication with extensive violation by separable operations

description: We give a conceptually simple necessary condition such that a separable quantum operation can be implemented by local operations on subsystems and classical communication between parties (LOCC), a condition which follows from a novel approach to understanding LOCC. This necessary condition holds for any number of parties and any finite number of rounds of communication and as such, also provides a completely general sufficient condition that a given separable operation cannot be exactly implemented by LOCC. Furthermore, it demonstrates an extremely strong difference between separable operations and LOCC, in that there exist examples of the former for which the condition is extensively violated. More precisely, the violation by separable operations of our necessary condition for LOCC grows without limit as the number of parties increases.

description: The geospace environment is volatile and highly driven. Space weather has effects on Earth's magnetosphere that cause a dynamic and enigmatic response in the thermosphere, particularly on the evolution of neutral mass density. Many models exist that use space weather drivers to produce a density response, but these models are typically computationally expensive or inaccurate for certain space weather conditions. In response, this work aims to employ a probabilistic machine learning (ML) method to create an efficient surrogate for the Thermosphere Ionosphere Electrodynamics General Circulation Model (TIE-GCM), a physics-based thermosphere model. Our method leverages principal component analysis to reduce the dimensionality of TIE-GCM and recurrent neural networks to model the dynamic behavior of the thermosphere much quicker than the numerical model. The newly developed reduced order probabilistic emulator (ROPE) uses Long-Short Term Memory neural networks to perform time-series forecasting in the reduced state and provide distributions for future density. We show that across the available data, TIE-GCM ROPE has similar error to previous linear approaches while improving storm-time modeling. We also conduct a satellite propagation study for the significant November 2003 storm which shows that TIE-GCM ROPE can capture the position resulting from TIE-GCM density with < 5 km bias. Simultaneously, linear approaches provide point estimates that can result in biases of 7 - 18 km.

description: This note is a brief response to Professor Azoulai's reaction (On Dubious Parallels: The Transnational Europeans and the Jews. A Note on Gareth Davies' Article, in European Papers, Vol. 5, 2020, No 1, forthcoming, www.europeanpapers.eu) to my Article, How Citizenship Divides (How Citizenship Divides: The New Legal Class of Transnational Europeans, in European Papers, Vol. 4, 2019, No 3, www.europeanpapers.eu, p. 675 et seq.). He takes exception to my suggestion that Jews in early 20th century Europe, like mobile Union Citizens, were in a sense outsiders within the states that were their homes, and as members of a pan-European persecuted minority, also in a sense transnational. He seems to think that to suggest a minority may have a different sense of place and belonging in their state is to insult them. I think that to deny it is to deny them a voice and identity, as well as to reinforce the nationalist idea that the only good citizen is an uncomplicated one.

description: Ce mémoire vise à décrire les enjeux liés à l’enseignement de la littérature extrêmement contemporaine aux classes de secondaire II en envisageant un dispositif didactique précis élaboré au sein d’un prix littéraire. Dans un premier temps, il envisage la problématique de l’enseignement de ce type de littérature au sein de ce degré d’enseignement. Puis, il explicite les opportunités et les défis qu’offrent le Roman des Romands, prix littéraire suisse qui vise à mettre en lumière l’espace littéraire romand. Enfin, il décrit en détail un dispositif didactique centré autour du compte-rendu critique afin d’illustrer la façon dont on peut profiter du prix littéraire pour employer des méthodes d’expression originales. Le compte-rendu critique donne aux étudiants un cadre suffisamment rigide pour qu’ils puissent s’appuyer dessus lors de la pratique tout en offrant de la souplesse pour leur permettre de s’investir personnellement dans l’écrit. Ce dernier point s’inscrit dans une nouvelle manière de considérer l’étude des textes littéraires, s’appuyant sur les émotions que provoquent le texte.

description: Creating interdisciplinary dialog in the field of socio-economics cannot be separated from the social diversity among scholarly voices within its community. In marking the 20th anniversary year of Socio-Economic Review (SER), this article examines the role of gender among authors and reviewers in SER. Our findings show that women remain underrepresented in terms of authorship and reviewing. While no gender differences exist in overall acceptance rates for submitted papers, a substantial gender gap exists in the number of submissions. Our analysis also highlights how the persistence of gender segregation is related to the predominance of male-only author teams and male-dominated research topics. The article concludes with suggestions for further research and a discussion on gender disparities in socio-economics and other social science fields.
