description: This paper is concerned with quantitative estimates for the Navier-Stokes equations. First we investigate the relation of quantitative bounds to the behaviour of critical norms near a potential singularity with Type I bound $\|u\|_{L^{\infty}_{t}L^{3,\infty}_{x}}\leq M$. Namely, we show that if $T^*$ is a first blow-up time and $(0,T^*)$ is a singular point then $$\|u(\cdot,t)\|_{L^{3}(B_{0}(R))}\geq C(M)\log\Big(\frac{1}{T^*-t}\Big),\,\,\,\,\,\,R=O((T^*-t)^{\frac{1}{2}-}).$$ We demonstrate that this potential blow-up rate is optimal for a certain class of potential non-zero backward discretely self-similar solutions. Second, we quantify the result of Seregin (2012), which says that if $u$ is a smooth finite-energy solution to the Navier-Stokes equations on $\mathbb{R}^3\times (0,1)$ with $$\sup_{n}\|u(\cdot,t_{(n)})\|_{L^{3}(\mathbb{R}^3)}

description: We present a planar spectro-polarimeter based on Fabry-P{é}rot cavities with embedded polarization-sensitive high-index nanostructures. A $7~μ$m-thick spectro-polarimetric system for 3 spectral bands and 2 linear polarization states is experimentally demonstrated. Furthermore, an optimal design is theoretically proposed, estimating that a system with a bandwidth of 127~nm and a spectral resolution of 1~nm is able to reconstruct the first three Stokes parameters \textcolor{black}{with a signal-to-noise ratio of -13.14~dB with respect to the the shot noise limited SNR}. The pixelated spectro-polarimetric system can be directly integrated on a sensor, thus enabling applicability in a variety of miniaturized optical devices, including but not limited to satellites for Earth observation.

description: Parametric amplification of attosecond coherent pulses around 100 eV at the single-atom level is demonstrated for the first time by using the 3D time-dependent Schr{ö}dinger equation in high-harmonic generation processes from excited states of He$^+$. We present the attosecond dynamics of the amplification process far from the ionization threshold and resolve the physics behind it. The amplification of a particular central photon energy requires the seed XUV pulses to be perfectly synchronized in time with the driving laser field for stimulated recombination to the He$^+$ ground state and is only produced in a few specific laser cycles in agreement with the experimental measurements. Our simulations show that the amplified photon energy region can be controlled by varying the peak intensity of the laser field. Our results pave the way to the realization of compact attosecond pulse intense XUV lasers with broad applications.
Analyse expérimentale du comportement d’arrachement des composites à matrice cimentaires

description: Cet article présente une étude expérimentale de la distribution de la contrainte de cisaillement à l'interface textile/matrice d'un essai d'arrachement (pull-out). Cette distribution est obtenue à l'aide de capteurs à fibre optique à résolution spatiale millimétrique. Ces fibres optiques ont été collées sur le fils permettant la mesure de sa déformation sur toute la longueur d'ancrage. Puis, par une analyse mécanique, l'évolution de la contrainte de cisaillement à l'interface textile/matrice est déduite. Les résultats obtenus montrent que cette contrainte de cisaillement n'est pas constante le long de la longueur d'ancrage. Cette contrainte de cisaillement présente une forme décroissante au fur et à mesure qu'elle se déplace sur la longueur d'ancrage à partir du point d'insertion du fil dans la matrice. Ce résultat a permis d'une part de corriger les hypothèses de calcul du comportement à l'arrachement dans la littérature qui suppose que cette contrainte de cisaillement est constante. D'autre part, cette étude permet une meilleure analyse du comportement en fissuration des composites à matrice cimentaire.

description: Instead of directly utilizing an observed image including some outliers, noise or intensity inhomogeneity, the use of its ideal value (e.g. noise-free image) has a favorable impact on clustering. Hence, the accurate estimation of the residual (e.g. unknown noise) between the observed image and its ideal value is an important task. To do so, we propose an $\ell_0$ regularization-based Fuzzy $C$-Means (FCM) algorithm incorporating a morphological reconstruction operation and a tight wavelet frame transform. To achieve a sound trade-off between detail preservation and noise suppression, morphological reconstruction is used to filter an observed image. By combining the observed and filtered images, a weighted sum image is generated. Since a tight wavelet frame system has sparse representations of an image, it is employed to decompose the weighted sum image, thus forming its corresponding feature set. Taking it as data for clustering, we present an improved FCM algorithm by imposing an $\ell_0$ regularization term on the residual between the feature set and its ideal value, which implies that the favorable estimation of the residual is obtained and the ideal value participates in clustering. Spatial information is also introduced into clustering since it is naturally encountered in image segmentation. Furthermore, it makes the estimation of the residual more reliable. To further enhance the segmentation effects of the improved FCM algorithm, we also employ the morphological reconstruction to smoothen the labels generated by clustering. Finally, based on the prototypes and smoothed labels, the segmented image is reconstructed by using a tight wavelet frame reconstruction operation. Experimental results reported for synthetic, medical, and color images show that the proposed algorithm is effective and efficient, and outperforms other algorithms.

description: The purpose of gamification is to foster the interest of the players/users and increase their involvement or direct certain behaviors. Specifically, it is a set of activities and processes to solve problems using or applying elements related to the game. This paper aims to explore the use of gamification to improve the customer experience in the retail field. This study is based on a qualitative approach with a literature review of the highly-influential articles on Web of Science and Scopus in Business and Management areas, referencing marketing experts. It also contains a case study on gamification. In Italy and in the Republic of San Marino, the company UCI Cinemas has implemented a promotional strategy for the sale of tickets for the film Fantastic Beats: The Crimes of Grindelwald. This promotional strategy is based on the combination of omnichannel retail and gamification.

description: Wannier functions of the one dimensional Schroedinger equation with elliptic one gap potentials are explicitly constructed. Properties of these functions are analytically and numerically investigated. In particular we derive an expression for the amplitude of the Wannier function in the origin, a power series expansion valid in the vicinity of the origin and an asymptotic expansion characterizing the decay of the Wannier function at large distances. Using these results we construct an approximate analytical expression of the Wannier function which is valid in the whole spatial domain and is in good agreement with numerical results.

The prediction of a car price has become a high-interest research area of great importance, as it requires significant initiative and knowledge of the field expert. I have applied to a highly comprehensive analysis with all data cleaning, exploration, visualization, feature selection and model building. The data used for the prediction was collected from the web portal fred.stlouisfed.org using a web scraper that was written in Python/Jupyter programming language. According to problem-solving, I have split it into 5 parts (Data understanding and exploration, Data cleaning, Data preparation: Feature Engineering and Scaling, Feature Selection using RFE and Model Building and Linear Regression Assumptions Validation and Outlier Removal).

Multipartite Purification, Multiboundary Wormholes and Islands in AdS$_{3}$/CFT$_{2}$

description: The holographic duals of Entanglement of Purification through the Entanglement Wedge Cross Section has been a well-discussed topic in the literature recently. More general entanglement measures involving multipartite information and their holographic duals have also been proposed. On the other hand, the recent intriguing program reproducing the Page Curve in Black hole entropy using the notion of islands has also been an obvious issue of attraction. A toy model involving Multiboundary wormholes in AdS$_{3}$ was able to capture many interesting facts about such calculations. In such a toy model, the notion of islands was intuitively connected to quantum error correction. We try to bridge the ideas of the two programs especially in AdS$_{3}$/CFT$_{2}$ and give a description of the islands in terms of multipartite entanglement of purification. This clarifies a few simplified assumptions made while describing the toy model and also enables us to understand the familiar information paradox within the framework of the same model.

description: A minimal model for multipole orders in CeB$_6$ shows that degeneracy of the quadrupole order parameters and strong spin-orbit coupling lead to peculiar temperature and magnetic-field dependences of the X-ray reflection intensity at superlattice Bragg points. Furthermore, the intensity depends sensitively on the surface direction. These theoretical results explain naturally recent X-ray experiments in phases II and III of CeB$_6$. It is predicted that under weak magnetic field perpendicular to the (111) surface, the reflection intensity should change non-monotonically as a function of temperature.

description: In this work, we have performed Monte Carlo simulations to study phase transitions in a mixed spin-1 and spin-3/2 Ising ferrimagnetic system on the square and cubic lattices and with two different single-ion anisotropies. This lattice is divided in two interpenetrating sublattices with spins $S^A = 1$ (states $\pm1$ and 0) on the sublattice $A$ and $S^B = 3/2$ (states $\pm 3/2$, $\pm 1/2$) on the sublattice $B$. We have used single-ion anisotropies $D_{A}$ and $D_{B}$ acting on the sites of the sublattice $A$ and $B$, receptively. We have determined the phase diagrams of the model in the temperature $T$ versus the single-ion anisotropies strength $D_A$ and $D_B$ plane and shown that the system exhibits both second- and first-order phase transitions. We also have shown that this system displays compensation points for some values of the anisotropies.
title: Assembling The Future: The Role Of Transactive Planning Theory In Generating Alternative Urban Strategies
Creators: name: Pascolo, Elena
Publisher: name: The Open University
Year: 2002

description: Conditions of uncertainty, rapid change and heightened social, economic and spatial inequalities are symptomatic of an Increasingly Internationalised and urbanised world system. These issues correspond to the emergence of an urban problematic that requires the requalification of planning’s tools and techniques. Within this context: How does planning go about assembling the future?

The Mont Fleur civic scenarios undertaken in South Africa (1991-1992), the Toekomstverkenningen Amsterdam (1998-1999), and the Bishopsgate Methodology Statement proposed for an inner-city development site in London (2002), are presented as illustrative examples of how, planning connects knowledge to action in the public domain, translates complexity, deals with the future; Do the tools and processes used in the examples, extend or limit the possibility of alternative urban strategies?

These questions, are a starting point from which to explore John Friedmann’s theory on Transactive Planning (1973). This theory is defined as a normative response to improving the practice of plannirig through a dialogical process that combines various forms of technical and experiential knowledge, through which a deeper understanding of issues surrounding a particular problem, is achieved. Within the present research framework. Transactive Planning is used to formulate the principles, tools and techniques of an approach corresponding to the conditions of an urban problematic.

The final question: ‘What kind of future do we want to assemble?” opens the discussion towards considering the role, not only of Transactive Planning, but of an urban imaginary as a way of rephrasing the urban problematic. The endgame is to refunction the notion of the future, not as “uncertainty” that has to be resolved, but as a creative process that generates innovative urban strategies.
Modélisation du comportement dynamique des plaques composites par une simple Théorie de Déformation en Cisaillement
Creators: name: Ibrahim, Klouche
Publisher: name: Academic Journal of Civil Engineering
Year: 2020

description: Dans le présent document, une simple théorie raffinée de déformation du cisaillement d’ordre n est appliquée pour l'analyse de vibration libre des plaques composites stratifiées. Le champ de déplacement proposé est basé sur une nouvelle cinématique utilisant des termes intégrales indéterminés et ne contient que quatre inconnues, contre cinq ou plus dans le cas d'autres théories d'ordre supérieur. La théorie actuelle explique une distribution adéquate des déformations de cisaillement transversales à travers l'épaisseur de la plaque et satisfait la nullité des contraintes de cisaillement aux surfaces supérieure et inférieure de la plaque, par conséquent, il n'exige pas de facteur de correction de cisaillement. Les équations de mouvement sont dérivées du principe d’Hamilton et résolues par l'approche de Navier pour obtenir des solutions. Les résultats numériques des fréquences naturelles adimensionnelles obtenues en utilisant la présente théorie sont comparés à ceux disponibles dans la littérature pour vérifier la validité des solutions actuelles. On peut conclure que la théorie raffinée actuelle est précise et efficace dans la prévision des fréquences naturelles des plaques composites isotropes.

Here we use nitrogen-vacancy centers in diamonds to detect electron spin resonance spectra of individual, tethered DNA duplexes labeled with a nitroxide spin label in aqueous buffer solutions at ambient temperatures. This paves the way for magnetic resonance studies on single biomolecules and their inter-molecular interactions in a native-like environment.

description: We examine the evolution of the sizes and number densities of disk galaxies using the high resolution images obtained by the Great Observatories Origins Deep Survey (GOODS) with the Advanced Camera for Surveys (ACS) on the Hubble Space Telescope (HST). The multiwavelength (B,V,i,z) images allow us to classify galaxies based on their rest-frame B-band morphologies out to redshift z = 1.25. In order to minimize the effect of selection biases, we confine our analysis to galaxies which occupy the region of magnitude-size plane where the survey is almost 90% complete at all redshifts. The observed size distribution is consistent with a log-normal distribution as seen for the disk galaxies in the local Universe and does not show any significant evolution over the redshift range 0.25 < z < 1.25. We find that the number densities of disk galaxies remains fairly constant over this redshift range, although a modest evolution by a factor of four may be possible within the 2-sigma uncertainties.

description: This paper mainly focuses on the problem of lossy compression storage from the perspective of message importance when the reconstructed data pursues the least distortion within limited total storage size. For this purpose, we transform this problem to an optimization by means of the importance-weighted reconstruction error in data reconstruction. Based on it, this paper puts forward an optimal allocation strategy in the storage of digital data by a kind of restrictive water-filling. That is, it is a high efficient adaptive compression strategy since it can make rational use of all the storage space. It also characterizes the trade-off between the relative weighted reconstruction error and the available storage size. Furthermore, this paper also presents that both the users' preferences and the special characteristic of data distribution can trigger the small-probability event scenarios where only a fraction of data can cover the vast majority of users' interests. Whether it is for one of the reasons above, the data with highly clustered message importance is beneficial to compression storage. In contrast, the data with uniform information distribution is incompressible, which is consistent with that in information theory.

Creators: name: Pouyanne, Aliénor
Publisher: name: Academic Journal of Civil Engineering
Year: 2020

description: Les environnements chimiquement agressifs, y compris certaines eaux minéralisées, peuvent conduire à une dégradation rapide des structures. Le béton est un milieu réactionnel complexe en constante évolution. La connaissance approfondie des mécanismes physico-chimiques mis en jeu par l’environnement agressif est indispensable au bon dimensionnement des structures. Comment rendre compte de phénomènes chimiques microscopiques à l’aide de paramètres accessibles par des essais de laboratoire ? A l’aide d’une simulation numérique, ce travail développe une stratégie performantielle de découplage des phénomènes microscopiques. Cette dernière est appliquée à l’étude de la lixiviation par deux eaux minérales et s’attache à montrer qu’une conception d’ouvrage adaptée à son environnement doit reposer sur une étude complète des caractéristiques de l’eau agressive.

description: We report on the methodology and first results from the Deep Lens Survey transient search. We utilize image subtraction on survey data to yield all sources of optical variability down to 24th magnitude. Images are analyzed immediately after acquisition, at the telescope and in near-real time, to allow for followup in the case of time-critical events. All classes of transients are posted to the web upon detection. Our observing strategy allows sensitivity to variability over several decades in timescale. The DLS is the first survey to classify and report all types of photometric and astrometric variability detected, including solar system objects, variable stars, supernovae, and short timescale phenomena. Three unusual optical transient events were detected, flaring on thousand-second timescales. All three events were seen in the B passband, suggesting blue color indices for the phenomena. One event (OT 20020115) is determined to be from a flaring Galactic dwarf star of spectral type dM4. From the remaining two events, we find an overall rate of η= 1.4 events deg-2 day-1 on thousand-second timescales, with a 95% confidence limit of η< 4.3. One of these events (OT 20010326) originated from a compact precursor in the field of galaxy cluster Abell 1836, and its nature is uncertain. For the second (OT 20030305) we find strong evidence for an extended extragalactic host. A dearth of such events in the R passband yields an upper 95% confidence limit on short timescale astronomical variability between 19.5 < R < 23.4 of η_R < 5.2. We report also on our ensemble of astrometrically variable objects, as well as an example of photometric variability with an undetected precursor.

description: We study the interaction of laser pulses carrying orbital angular momentum (OAM) with structural asymmetry quantum dot molecules characterized by four energy levels. We demonstrate how the inter-dot tunneling endows exchange of optical vortices between different frequencies. We consider a case where a weak probe beam has an optical vortex and thus has a zero intensity at the center. The presence of tunneling coupling generates an additional weak laser beam with the same vorticity as that of the incident vortex beam. We analyze conditions for the vortex of the initial beam to be transferred efficiently to the generated beam. The propagation of Laguerre-Gaussian (LG) beams possessing OAM states characterized by both azimuthal and radial indices is then investigated for the case where the strong control beam is also an OAM mode. It is shown that the conservation of OAM states is always satisfied over the OAM exchange process. Yet, an abnormal case is observed in which the radial index induces some intensity patterns of the generated beam which differs from a pure LG beam of incident beams. Analytical solutions are provided to elucidate such effects induced by radial indices on propagation characteristics of OAM beams. When superimposing two initially present weak OAM modes, it is observed that the resulting optical vortices move about the beam axis as the light propagates, forming a sort of "constellation" around the center. The shift in axis of such a composite pulses is due to the effect of inter-dot tunneling which is controlled by an external electric voltage. The optical angular momenta may add a new degree of freedom in the study of solid systems suitable for quantum technologies.

description: Vitamin D is a fat-soluble organic molecule considered as a pro-hormone, playing a key role in phosphocalcic homeostasis. Its normal and pathological values are based on expert consensus. Hypovitaminosis D has been defined as a vitamin D level less than 30 ng/mL. It is a very common situation around the world, and in Morocco in particular. In practice, the dosage of vitamin D suffers from an over-prescription, generating considerable costs in public health. This has led to the development of national recommendations to promote health economy. In this sense, the prevention of hypovitaminosis D is fundamental, and requires the recognition of its risk factors and clinical manifestations. Management can be done at different levels. Primary prevention is based on the management of risk factors. Secondary prevention aims to detect asymptomatic cases to treat them before the stage of complications. Finally, tertiary prevention aims to act on complications and the risk of recurrence, and is based on drug treatment constituted of attack and maintenance phases
description: La vitamine D est une substance organique liposoluble considérée comme une prohormone, ouant un rôle clé dans l’homéostasie phosphocalcique. Ses valeurs normales et pathologiques sont basées sur un consensus d’experts. L’hypovitaminose D a été définie par un taux de vitamine D inférieur à 30 ng/ mL. C’est une situation très fréquente de par le monde, et au Maroc en particulier. En pratique, le dosage de la vitamine D est victime d’une prescription abusive, engendrant des coûts considérables en santé publique. Ceci a conduit à l’élaboration de recommandations nationales pour favoriser l’économie de la santé. Dans ce sens, la prévention de l’hypovitaminose D est fondamentale, et passe par la reconnaissance de ses facteurs de risque et de ses manifestations cliniques. La prise en charge peut se faire à différents niveaux. La prévention primaire repose sur la gestion des facteurs de risque. La prévention secondaire a pour but de dépister les cas asymptomatiques et les traiter avant le stade de complications. Enfin, la prévention tertiaire vise à agir sur les complications et les risques de récidive, et repose sur le traitement médicamenteux avec une phase d’attaque et d’entretien
A comment on "Lense-Thirring frame dragging induced by a fast-rotating white dwarf in a binary pulsar system" by V. Venkatraman Krishnan et al

description: We comment on a recent study reporting evidence for the general relativistic Lense-Thirring secular precession of the inclination $I$ of the orbital plane to the plane of the sky of the tight binary system PSR J1141-6545 made of a white dwarf and an emitting radiopulsar of comparable masses. The quadrupole mass moment $Q_2^\mathrm{c}$ and the angular momentum ${\boldsymbol S}^\mathrm{c}$ of the white dwarf cause the detectable effects on $I$ with respect to the present-day accuracy in the pulsar's timing. The history-dependent and model-dependent assumptions to be made on $Q_2^\mathrm{c}$ and ${\boldsymbol S}^\mathrm{c}$, required even just to calculate the analytical expressions for the resulting post-Keplerian precessions, may be deemed as too wide in order to claim a successful test of the Einsteinian gravitomagnetic effect. Moreover, depending on how $Q_2^\mathrm{c}$ is calculated, the competing quadrupole-induced rate of change, which is a major source of systematic uncertainty, may be up to $\lesssim 30-50\%$ of the Lense-Thirring effect for most of the allowed values in the 3D parameter space spanned by the white dwarf's spin period $P_\mathrm{s}$, and the polar angles $i_\mathrm{c},\,ζ_\mathrm{c}$ of its spin axis. The possible use of the longitude of periastron $\dot\varpi$ is investigated as well. It turns out that a measurement of its secular precession, caused, among other things, also by $Q_2^\mathrm{c},\,{\boldsymbol{S}}^\mathrm{c}$, could help in further restricting the permitted regions in the white dwarf's parameter space.
