description: The Managed Care system within Medicaid (US Healthcare) uses Request For Proposals (RFP) to award contracts for various healthcare and related services. RFP responses are very detailed documents (hundreds of pages) submitted by competing organisations to win contracts. Subject matter expertise and domain knowledge play an important role in preparing RFP responses along with analysis of historical submissions. Automated analysis of these responses through Natural Language Processing (NLP) systems can reduce time and effort needed to explore historical responses, and assisting in writing better responses. Our work draws parallels between scoring RFPs and essay scoring models, while highlighting new challenges and the need for interpretability. Typical scoring models focus on word level impacts to grade essays and other short write-ups. We propose a novel Bi-LSTM based regression model, and provide deeper insight into phrases which latently impact scoring of responses. We contend the merits of our proposed methodology using extensive quantitative experiments. We also qualitatively asses the impact of important phrases using human evaluators. Finally, we introduce a novel problem statement that can be used to further improve the state of the art in NLP based automatic scoring systems.

description: Nicknamed as the "Parrot of India" for his exceptional eloquence, Amīr Khusraw of Delhi (1253–1325) wrote elaborate prose introductions to all his dīvāns, but the one he wrote to his Ghurrat al-kamāl (The Full Moon of Perfection)—compiled around 1293–94, at the approximate age of 43—is particularly important because of his critique of Arabic and Persian poetry in general, and the critique of his own writing in particular. As a literary critique by an author of Turko-Indian background, who emulated the styles of various great Persian poets from Ghazni (in modern-day Afghanistan) to Shiraz and Isfahan (in modern-day Iran), to Ganja (in modern-day Azerbaijan), Amīr Khusraw's work would provide valuable insights into the literary sphere of the medieval Persianate world. The present paper summarizes the author's first part of the introduction to his third dīvān, Ghurrat al-kamāl (The Full Moon of Perfection), followed by an English translation of the section where he critiques his own poetry and prose.

description: Las redes sociales se han introducido de lleno en nuestra vida diaria con el propósito de facilitar el intercambio de información, la interacción y la colaboración entre sus usuarios. Pueden constituir, por lo tanto, una potente herramienta pedagógica, que hemos decidido utilizar para ayudar a nuestros alumnos, del departamento de Estudios Hispánicos de la Universidad Ibn Zohr de Agadir (Marruecos), a desarrollar su competencia lingüística y cultural en español. De hecho, hemos creado grupos de chats en las redes sociales que ellos usan mayoritariamente (Facebook y WhatsApp) para interactuar y compartir con ellos material de apoyo de índole lingüística, social y cultural sobre el mundo hispano. Dicha experiencia comenzó en 2016 y permanece hasta hoy en día. A finales de 2019, les propusimos a los alumnos participar en una encuesta sociolingüística para que valorasen la experiencia y para estratificar socialmente su grado de participación en español dentro de ese espacio virtual. En esta comunicación, presentaremos los resultados de dicha encuesta, como primera etapa de nuestra investigación. La segunda etapa se centrará en el análisis de los errores de español que cometen nuestros alumnos en dichas redes sociales desde una perspectiva sociolingüística.

description: Singularities in Newton's gravitation, in general relativity (GR), in Coulomb's law, and elsewhere in classical physics, stem from two ill conceived assumptions: a) there are point-like entities with finite masses, charges, etc., packed in zero volumes, and b) the non-quantum assumption that these point-likes can be assigned precise coordinates and momenta. In the case of GR, we argue that the classical energy-momentum tensor in Einstein's field equation is that of a collection of point particles and is prone to singularity. In compliance with Heisenberg's uncertainty principle, we suggest to replace each constituent of the gravitating matter with a suitable quantum mechanical equivalent, here a Klien-Gordon (KG) or a Yukawa-ameliorated version of it, YKG field. KG and YKG fields are spatially distributed entities. They do not end up in singular spacetime points nor predict singular blackholes.
 On the other hand, YKG waves reach infinity as $\frac{1}{r}e^{-(κ\pm i k)r}$. They create the Newtonian $r^{-2}$ term as well as a non-Newtonian $r^{-1}$ force. The latter is capable of explaining the observed flat rotation curves of spiral galaxies, and is interpretable as an alternative gravity, a dark matter scenario, etc. There are ample observational data on flat rotation curves of spiral galaxies, coded in the Tully-Fisher relation, to support our propositions.

description: La larga presencia de los árabes en España (Al Ándalus) tuvo un enorme impacto en la lengua española. Una de las huellas indelebles que la civilización arábigo-musulmana dejó, es de índole lingüística, particularmente en la parcela léxica. El influjo árabe en las lenguas neolatinas ha sido el objeto de muchos estudios cuyo denominador común ha sido y sigue siendo resaltar, sobre todo, la contribución de la civilización árabe a la formación del léxico tanto español como él de las lenguas neolatinas, peculiarmente, el portugués y el italiano. El presente artículo tiene como propósito echar luz sobre cómo la lengua árabe repercutió positivamente en la lengua española. Lo iniciaremos con una introducción histórica poniendo de relieve las etapas de la estancia de los árabes en Al Ándalus, destacaremos luego el contexto lingüístico con la predominación de la lengua árabe para entrar en el meollo de nuestro artículo resaltando cómo contribuyó la lengua árabe a la formación del léxico español subrayando las épocas de mayor introducción de los arabismos.

description: As simulation is increasingly used in scenario-based approaches to test Automated Driving Systems, the credibility of simulation results is a major concern. Arguably, credibility depends on the validity of the simulation setup and simulation models. When selecting appropriate simulation models, a trade-off must be made between validity, often connected to the model's fidelity, and cost of computation. However, due to the large number of test cases, expert-based methods to create sufficiently valid simulation setups seem infeasible. We propose using design contracts in order to semi-automatically compose simulation setups for given test cases from simulation models and to derive requirements for the simulation models, supporting separation of concerns between simulation model developers and users. Simulation model contracts represent their validity domains by capturing a validity guarantee and the associated operating conditions in an assumption. We then require the composition of the simulation model contracts to refine a test case contract. The latter contract captures the operating conditions of the test case in its assumption and validity requirements in its guarantee. Based on this idea, we present a framework that supports the compositional configuration of simulation setups based on the contracts and a method to derive runtime monitors for these simulation setups.

description: This paper proposes model-free imitation learning named Entropy-Regularized Imitation Learning (ERIL) that minimizes the reverse Kullback-Leibler (KL) divergence. ERIL combines forward and inverse reinforcement learning (RL) under the framework of an entropy-regularized Markov decision process. An inverse RL step computes the log-ratio between two distributions by evaluating two binary discriminators. The first discriminator distinguishes the state generated by the forward RL step from the expert's state. The second discriminator, which is structured by the theory of entropy regularization, distinguishes the state-action-next-state tuples generated by the learner from the expert ones. One notable feature is that the second discriminator shares hyperparameters with the forward RL, which can be used to control the discriminator's ability. A forward RL step minimizes the reverse KL estimated by the inverse RL step. We show that minimizing the reverse KL divergence is equivalent to finding an optimal policy. Our experimental results on MuJoCo-simulated environments and vision-based reaching tasks with a robotic arm show that ERIL is more sample-efficient than the baseline methods. We apply the method to human behaviors that perform a pole-balancing task and describe how the estimated reward functions show how every subject achieves her goal.

description: Flat bands (FBs) in materials can enhance the correlation effects, resulting in exotic phenomena. Line graph (LG) lattices are well known for hosting FBs with isotropic hoppings in $s$-orbital models. Despite their prevalent application in the Kagome metals, there has been a lack of a general approach for incorporating higher-angular-momentum orbitals with spin-orbit couplings (SOCs) into LGs to achieve FBs. Here, we introduce a non-Abelian LG theory to construct FBs in realistic systems, which incorporates internal degrees of freedom and goes beyond $s$-orbital models. We modify the lattice edges and sites in the LG to be associated with arbitrary Hermitian matrices, referred to as the multiple LG. A fundamental aspect involves mapping the multiple LG Hamiltonian to a tight-binding (TB) model that respects the lattice symmetry through appropriate local non-Abelian transformations. We establish the general conditions to determine the local transformations. Based on this mechanism, we demonstrate the realization of $d$-orbital FBs in the Kagome lattice, which could serve as a minimal model for understanding the FBs in transition metal Kagome materials. Our approach bridges the gap between the known FBs in pure lattice models and their realization in multi-orbital systems.

description: In reality, the role of surveyors and cartographers throughout history was often far from peaceful. It was their initial explorations that paved the way for destructive waves of colonising armies and civilians. At each stage of mapping an area, clues are preserved about the priorities and prejudices of the person wielding the pencil, and those instructing them. Today, researchers can spot these clues and draw out the contextual history of the time.

description: Berry curvature, a momentum space property, can manifest itself in current responses. The well-known anomalous Hall effect in time-reversal-breaking systems arises from a Berry curvature monopole. In time-reversal-invariant materials, a second-order Hall conductivity emerges from a Berry curvature dipole. Recently, it has been shown that a Berry curvature quadrupole induces a third-order ac Hall response in systems that break time reversal ($K$) and a fourfold rotational ($C_{4}$) symmetry, while remaining invariant under the combination of the two ($C_{4}K$). In this letter, we demonstrate that incident light can induce a $\rm dc$ Hall current in such systems, driven by the Berry curvature quadrupole. We consider a combination of a static $\rm dc$ electric field and an ac light-induced electric field. We calculate the current perpendicular to both the static electric field and the fourfold axis. Remarkably, the induced current is generically spin-polarized. A net charge current appears for light that is linearly or elliptically polarized, but not for circular polarization. In contrast, the spin current remains unchanged when the polarization of light is varied. This allows for rich possibilities such as generating a spin current by shining circularly polarized light on an altermagnetic material. We demonstrate this physics using a two-dimensional toy model for altermagnets.

description: Recent progress in deep learning has led to the development of Optical Character Recognition (OCR) systems which perform remarkably well. Most research has been around recurrent networks as well as complex gated layers which make the overall solution complex and difficult to scale. In this paper, we present an Efficient And Scalable TExt Recognizer (EASTER) to perform optical character recognition on both machine printed and handwritten text. Our model utilises 1-D convolutional layers without any recurrence which enables parallel training with considerably less volume of data. We experimented with multiple variations of our architecture and one of the smallest variant (depth and number of parameter wise) performs comparably to RNN based complex choices. Our 20-layered deepest variant outperforms RNN architectures with a good margin on benchmarking datasets like IIIT-5k and SVT. We also showcase improvements over the current best results on offline handwritten text recognition task. We also present data generation pipelines with augmentation setup to generate synthetic datasets for both handwritten and machine printed text.

description: La didáctica de las lenguas extranjeras con fines específicos es una tendencia definida por Hutchinson y Waters (1987) como el “enfoque de la enseñanza de lenguas que tiene como meta satisfacer las necesidades de comunicación de un grupo específico de aprendices. En este marco se inscribe el debate relacionado con la denominación “Español con Fines Específicos” -surgida a partir de los años ochenta y extendida a comienzos de la década de los 90- que “ha pasado a constituir una de las ramas más relevantes de la enseñanza del español como lengua extranjera” (Diccionario de términos clave de ELE, 2008)”. Asimismo, Marrueco es uno de los países en el que cada vez se está mostrando un gran interés por la enseñanza-aprendizaje del Español con Fines Específicos. En el presente trabajo, recorremos el panorama actual de la enseñanza superior reglada marroquí y presentamos al mismo tiempo cómo se organiza el Español con Fines Generales y el Español con Fines Específicos en este sector; empezamos por la presentación de la enseñanza superior pública marroquí, del estado de la cuestión del Español con Fines Generales, así como del Español con Fines Específicos en los establecimientos superiores públicos, especialmente, en las Escuelas Nacionales de Comercio y Gestión. Basándonos en los resultados de este estudio, presentamos también nuestra reflexión que incita a un cambio de óptica con respecto al lugar del español en Marruecos, marcado por una pérdida de protagonismo en el ámbito educativo marroquí, asociando la importancia de esta lengua con su valor económico. Por tanto, podemos valernos del Español con Fines Específicos, especialmente, del Español de los Negocios como palanca para revalorizar la presencia del español en el sistema educativo marroquí.

description: Consider $N$ stations interconnected with links, each of capacity $K$, forming a complete graph. Calls arrive to each link at rate $λ$ and depart at rate $1$. If a call arrives to a link $x y$, connecting stations $x$ and $y$, which is at capacity, then a third station $z$ is chosen uniformly at random and the call is attempted to be routed via $z$: if both links $x z$ and $z y$ have spare capacity, then the call is held simultaneously on these two; otherwise the call is lost. We analyse an approximation of this model. We show rigorously that there are three phases according to the traffic intensity $α:= λ/K$: for $α\in (0,α_c) \cup (1,\infty)$, the system has mixing time logarithmic in the number of links $n := \binom N2$; for $α\in (α_c,1)$ the system has mixing time exponential in $n$, the number of links. Here $α_c := \tfrac13 (5 \sqrt{10} - 13) \approx 0.937$ is an explicit critical threshold with a simple interpretation. We also consider allowing multiple rerouting attempts. This has little effect on the overall behaviour; it does not remove the metastability phase. Finally, we add trunk reservation: in this, some number $σ$ of circuits are reserved; a rerouting attempt is only accepted if at least $σ+1$ circuits are available. We show that if $σ$ is chosen sufficiently large, depending only on $α$, not $K$ or $n$, then the metastability phase is removed.

description: We present a robust shadow estimation protocol for wide classes of low-depth measurement circuits that mitigates noise as long as the effective measurement map including noise is locally unitarily invariant. This is in practice an excellent approximation, encompassing for instance the case of ideal single-qubit Clifford gates composing the first circuit layer of an otherwise arbitrary circuit architecture and even non-Markovian, gate-dependent noise in the rest of the circuit. We argue that for weakly-correlated local noise, the measurement channel has an efficient matrix-product representation, and show how to estimate this directly from experimental data using tensor-network tools, eliminating the need for analytical or numeric calculations. We illustrate the relevance of our method with both numerics and proof-of-principle experiments on an IBM Quantum device. Numerically, we show that unmitigated shallow shadows with noisy circuits become more biased as the depth increases. In contrast, using the same number of samples, robust ultra-shallow shadows become more precise with increasing depth for relevant parameter regimes. The gain in sample efficiency is still limited by the noise per gate, resulting in an optimal circuit depth per noise level. Experimentally, we observe improved precision in two simple fidelity estimation tasks using five-qubit circuits with up to two layers of entangling gates, by about an order of magnitude. Under the practical constraints of current and near-term noisy quantum devices, our method maximally realizes the potential of shadow estimation with global rotations and identifies its fundamental limitations in the presence of noise.

Pour une approche sociodidactique de l’hétérogénéité du profil socio-culturel des apprenants Le cas de l’enseignement-apprentissage du FLE

Subjects: analyse sociolinguistique ; contexte familial; facteurs extrascolaires; hétérogénéité

description: L’objectif de ce travail est de mettre en avant le rôle majeur que peut jouer la sociolinguistique dans l’explication des difficultés d’enseignement-apprentissage du français rencontrées par les élèves marocains et de les réduire. Ces difficultés ne s’expliquent pas exclusivement par les aspects scolaires, techniques, formels et systémiques mais également par des facteurs extrascolaires tels que le contexte socio-économique et culturels des apprenants. Pour le montrer, nous avons mené une recherche de terrain auprès de 147 élèves de la sixième année du cycle primaire issus de deux milieux contrastés. Après leur avoir passé un test de français, nous avons collecté, à l’aide d’un questionnaire, leurs caractéristiques socio-économiques et culturelles afin de les croiser avec leurs résultats, les analyser et les interpréter. Cette analyse montre une forte corrélation entre les conditions extrascolaires de l’élève et ses résultats. De là, nous constatons que plus les apprenants sont issus de milieu favorisé plus leurs notes au test sont relativement meilleures aux élèves issus de milieux défavorisés et inversement.

description: The nature of the zero-temperature phase diagram of the spin-$1/2$ $J_1$-$J_2$ Heisenberg model on a square lattice has been debated in the past three decades, which may hold the key to understand high temperature superconductivity. By using the state-of-the-art tensor network method, specifically, the finite projected entangled pair state (PEPS) algorithm, to simulate the global phase diagram the $J_1$-$J_2$ Heisenberg model up to $24\times 24$ sites, we provide very solid evidences to show that the nature of the intermediate nonmagnetic phase is a gapless quantum spin liquid (QSL), whose spin-spin and dimer-dimer correlations both decay with a power law behavior. There also exists a valence-bond solid (VBS) phase in a very narrow region $0.56\lesssim J_2/J_1\leq0.61$ before the system enters the well known collinear antiferromagnetic phase. The physical nature of the discovered gapless QSL and potential experimental implications are also addressed. We stress that we make the first detailed comparison between the results of PEPS and the well-established density matrix renormalization group (DMRG) method through one-to-one direct benchmark for small system sizes, and thus give rise to a very solid PEPS calculation beyond DMRG. Our numerical evidences explicitly demonstrate the huge power of PEPS for precisely capturing long-range physcis for highly frustrated systems, and also demonstrate the finite PEPS method is a very powerful approach to study strongly corrleated quantum many-body problems.

Subjects: Borges ; traduction ; histoire littéraire ; texte définitif ; infini.

description: Pour Borges, traduire c’est dépasser les sens isolés des mots qui ne résident pas dans le texte, mais qui se constituent et se forment grâce au lecteur. La lecture n’est pas uniquement un acte qui permet de déchiffrer les phrases du texte. Elle peut prendre la forme d’une traduction qui alimente et enrichit le texte source. Si grâce à la réception du texte on peut lui attribuer différents sens, la traduction se présente comme une des lectures multiples et plurielles du texte assurée par sa réception. Le traducteur en tant que récepteur du texte original inscrit son travail dans le cadre d’une lecture plurielle. La traduction comme l’une des formes de la réception fait de l’art de la traductologie une représentation de l’infidélité créative du traducteur.

Absolute clock synchronization with a single time-correlated photon pair source over 10km

description: We demonstrate a point-to-point clock synchronization protocol based on bidirectionally propagating photons generated in a single spontaneous parametric down-conversion (SPDC) source. Tight timing correlations between photon pairs are used to determine the single and round-trip times measured by two separate clocks, providing sufficient information for distance-independent absolute synchronization secure against symmetric delay attacks. We show that the coincidence signature useful for determining the round-trip time of a synchronization channel, established using a 10\,km telecommunications fiber, can be derived from photons reflected off the end face of the fiber without additional optics. Our technique allows the synchronization of multiple clocks with a single reference clock co-located with the source, without requiring additional pair sources, in a client-server configuration suitable for synchronizing a network of clocks.

Is the panel fair? Evaluating panel compositions through network analysis. The case of research assessments in Italy

description: Research evaluation is usually governed by panels of peers. Procedural fairness refers to the principles that ensures decisions are made through a fair and transparent process. It requires that the composition of panels is fair. A fair panel is usually defined in terms of observable characteristics of scholars such as gender or affiliations. The formal adherence to these criteria is not sufficient to guarantee a fair composition in terms of scholarly thinking, background, or policy orientation. An empirical strategy for exploring the fairness in the intellectual composition of panels is proposed, based on the observation of links between panellists. The case study regards the three panels selected to evaluate research in economics, statistics and business during the Italian research assessment exercises. The first two panels were appointed directly by the governmental agency responsible for the evaluation, while the third was randomly selected. Hence the third panel can be considered as a control for evaluating about the fairness of the others. The fair representation is explored by comparing the networks of panellists based on their co-authorship relations, the networks based on journals in which they published and the networks based on their affiliated institutions (universities, research centres and newspapers). The results show that the members of the first two panels had connections much higher than the members of the control group. Hence the composition of the first two panels should be considered as unfair, as the results of the research assessments.

Quelques modalités combinatoires du discours mixte au Maroc : la morphologie du verbe français inséré dans le syntagme verbal de l’arabe marocain.

description: Ce propos examine les différentes modalités d’intégration morphologique des verbes français insérés dans le syntagme verbal de la matrice de l’arabe marocain dans le cadre de la pratique langagière d’alternance de codes. Il s’agit plus précisément d’analyser qualitativement les modalités d’accommodation morphologique développées par les verbes français lorsqu’ils sont enchâssés dans des énoncés mixtes à base d’arabe marocain. Pour ce faire, l’étude analysera un corpus composé d’énoncés mixtes enregistrés sur les ondes de quatre radios privées marocaines où les intervenant se livrent à des démonstrations d’avis en l’absence de toute pression ou du cadre formel à respecter, ce qui fait surgir le discours mixte où l’arabe marocain et le français sont massivement alternés. L’analyse mettra en exergue six paramètres mobilisés par la flexion verbale de l’arabe marocain pour contenir les radicaux verbaux français qui s’y insèrent. Cet insertion entraîne un conflit d’ordre au sein du syntagme verbal de la langue accueillante entre la flexion de la langue matrice et la langue enchâssée qui développe des comportements morphologiques pour qu’elle se rattache aux structures de la flexion qui les entourent.
