description: We present analytic results for all planar two-loop Feynman integrals contributing to five-particle scattering amplitudes with one external massive leg. We express the integrals in terms of a basis of algebraically-independent transcendental functions, which we call one-mass pentagon functions. We construct them by using the properties of iterated integrals with logarithmic kernels. The pentagon functions are manifestly free of unphysical branch cuts, do not require analytic continuation, and can be readily evaluated over the whole physical phase space of the massive particle production channel. We develop an efficient algorithm for their numerical evaluation and present a public implementation suitable for direct phenomenological applications.

description: We report the experimental observation of superradiant emission emanating from an elongated dense ensemble of laser cooled two-level atoms, with a radial extent smaller than the transition wavelength. In the presence of a strong driving laser, we observe that the system is superradiant along its symmmetry axis. This occurs even though the driving laser is orthogonal to the superradiance direction. This superradiance modifies the spontaneous emission, and, resultantly, the Rabi oscillations. We also investigate Dicke superradiance in the emission of an almost fully-inverted system as a function of atom numnber. The experimental results are in qualitative agreement with ab-initio, beyond-mean-field calculations.

description: The ionization and thermal state of the intergalactic medium (IGM) during the epoch of reionization has been of interest in recent times because of their close connection to the first stars. We present in this paper a semi-numerical code which computes the large-scale temperature and ionized hydrogen fields in a cosmologically representative volume accounting for the patchiness in these quantities arising from reionization. The code is an extension to a previously developed version for studying the growth of ionized regions, namely, Semi Numerical Code for ReionIzation with PhoTon Conservation (SCRIPT). The main additions in the present version are the inhomogeneous recombinations which are essential for temperature calculations. This extended version of SCRIPT also implements physical consequences of photoheating during reionization, e.g., radiative feedback. These enhancements allow us to predict observables which were not viable with the earlier version. These include the faint-end of the ultra-violet luminosity function of galaxies (which can get affected by the radiative feedback) and the temperature-density relation of the low-density IGM at $z\sim 6$. We study the effect of varying the free parameters and prescriptions of our model on a variety of observables. The conclusion of our analysis is that it should be possible to put constraints on the evolution of thermal and ionization state of the IGM using available observations accounting for all possible variations in the free parameters. A detailed exploration of the parameter space will be taken up in the future.

description: Brain science and artificial intelligence have made great progress toward the understanding and engineering of the human mind. The progress has accelerated significantly since the turn of the century thanks to new methods for probing the brain (both structure and function), and rapid development in deep learning research. However, despite these new developments, there are still many open questions, such as how to understand the brain at the system level, and various robustness issues and limitations of deep learning. In this informal essay, I will talk about some of the concepts that are central to brain science and artificial intelligence, such as information and memory, and discuss how a different view on these concepts can help us move forward, beyond current limits of our understanding in these fields.

description: Closeness is a global measure of centrality in networks, and a proxy for how influential actors are in social networks. In most network models, and many empirical networks, closeness is strongly correlated with degree. However, in social networks there is a cost of maintaining social ties. This leads to a situation (that can occur in the professional social networks of executives, lobbyists, diplomats and so on) where agents have the conflicting objectives of aiming for centrality while simultaneously keeping the degree low. We investigate this situation in an adaptive network-evolution model where agents optimize their positions in the network following individual strategies, and using only local information. The strategies are also optimized, based on the success of the agent and its neighbors. We measure and describe the time evolution of the network and the agents' strategies.

description: L'article présente une méthodologie pour établir une cartographie d'alarme de corrosion liée aux niveaux de corrosion des armatures de la première couche dans des structures en béton armé (RC). Les données d'inspection par contrôle non destructifs (CND) obtenues à partir de campagnes d'inspection sur différentes structures RC sont utilisées pour construire un modèle prédictif basé sur un réseau bayésien (RB). La méthodologie consiste en trois étapes principales : la construction de la base de données à partir des données d'inspection CND, l'apprentissage de la structure du RB et de ses paramètres à partir des données CND, et l'utilisation du RB pour avoir la cartographie des alarmes de corrosion. L'incertitude des mesures sur site est prise en compte dans ce modèle prédictif pour améliorer la précision des probabilités d'alarme de corrosion obtenues. Les paramètres de la structure RB physiquement optimale sont le potentiel de corrosion, le taux de corrosion, la résistivité électrique et l'alarme de corrosion. Les données d'inspection CND d'une face de pile de pont sont utilisées comme nouvelles informations pour mettre à jour le RB dans la dernière étape. La méthodologie permet d'estimer la probabilité d'alarme de corrosion lorsque les indicateurs ne sont pas disponibles simultanément (en raison des contraintes de mesures CND sur site). La cartographie obtenue à partir du modèle prédictif RB peut être utilisée comme un outil efficace pour la stratégie de maintenance en indiquant les zones les plus critiques de la structure inspectée vis-à-vis de la corrosion.

description: The chaotic dynamics of directly modulated semiconductor lasers with delayed optoelectronic feedback is studied numerically. The effects of positive and negative delayed optoelectronic feedback in producing chaotic outputs from such lasers with nonlinear gain reduction in its optimum value range is investigated using bifurcation diagrams. The results are confirmed by calculating the Lyapunov exponents. A negative delayed optoelectronic feedback configuration is found to be more effective in inducing chaotic dynamics to such systems with nonlinear gain reduction factor in the practical value range.

description: The up-down asymmetry in transversally polarized electron proton scattering is induced by the interference between one and two photon exchange amplitudes. Inelastic intermediate hadronic states (different from one-proton state) of the two photon exchange amplitude give rise to contributions containing the square of "large logarithm" (logarithm of the ratio of the transferred momentum to the electron mass). We investigate the presence of such contributions in higher orders of perturbation theory. The relation with the case of zero transfer momentum is explicitly given. The mechanism of cancellation of infrared singularities is discussed.

description: The two-dimensional organic superconductor $λ$-(BETS)$_2$GaCl$_4$ exhibits pronounced charge fluctuations below $T \approx 150$~K, in contrast to the sibling compound $κ$-(BETS)$_2$GaCl$_4$ that remains metallic down to milli-Kelvin. Infrared spectroscopy reveals only minor splitting in the vibrational features of the latter compound, common to other strongly dimerized $κ$-salts. When the organic molecules are arranged in the $λ$-pattern, however, a strong vibrational $ν_{27}(b_{1u})$ mode is present, that forms a narrow doublet. %indicating static charge imbalance of about 2\%. Most important, when cooling $λ$-(BETS)$_2$GaCl$_4$ below 150~K, two weak side modes appear due to charge disproportionation that amounts to $2δ=0.14e$. In analogy to the $β^{\prime\prime}$-type organic conductors, we propose that charge fluctuations play an important role in emerging of unconventional superconductivity in ł at $T_c=4.7$~K. We discuss the possibility of a charge-density-wave that coexists with the proposed spin-density-wave state.

description: As a generic example of a voltage-driven superconducting structure we study a short superconductor connected to normal leads by means of low transparency tunnel junctions, with a voltage bias $V$ between the leads. The superconducting order parameter $Δ$ is to be determined self-consistently. We study the stationary states of the system as well as the dynamics after a perturbation. We find a region in parameter space where there are two stable stationary states at a given voltage. These bi-stable states are distinguished by distinct values of the superconducting order parameter $Δ$ and of the current between the leads. We have evaluated (1) the multi-valued superconducting order parameter $Δ$ at given $V$; (2) the current between the leads at a given V; and (3) the critical voltage at which superconductivity in the island ceases. With regards to dynamics, we find numerical evidence that the stationary states are stable and that no complicated non-stationary regime can be induced by changing the voltage. This result is somewhat unexpected and by no means trivial, given the fact that the system is driven out of equilibrium. The response to a change in the voltage is always gradual, even in the regime where changing the interaction strength induces rapid anharmonic oscillations of the order parameter.

description: We present exact results on a novel kind of emergent random matrix universality that quantum many-body systems at infinite temperature can exhibit. Specifically, we consider an ensemble of pure states supported on a small subsystem, generated from projective measurements of the remainder of the system in a local basis. We rigorously show that the ensemble, derived for a class of quantum chaotic systems undergoing quench dynamics, approaches a universal form completely independent of system details: it becomes uniformly distributed in Hilbert space. This goes beyond the standard paradigm of quantum thermalization, which dictates that the subsystem relaxes to an ensemble of quantum states that reproduces the expectation values of local observables in a thermal mixed state. Our results imply more generally that the distribution of quantum states themselves becomes indistinguishable from those of uniformly random ones, i.e. the ensemble forms a quantum state-design in the parlance of quantum information theory. Our work establishes bridges between quantum many-body physics, quantum information and random matrix theory, by showing that pseudo-random states can arise from isolated quantum dynamics, opening up new ways to design applications for quantum state tomography and benchmarking.

description: Pour assurer les conditions convenables de pression dans les réseaux de distribution d'eau potable, les réservoirs en béton armé sont souvent réalisés sur les sommets de collines ou des monticules. C’est la raison pour laquelle, ces structures sont soumises à des actions climatiques extrêmement agressives. En Algérie, la plupart de ces réservoirs ont été construits à partir des années 1970, et plusieurs dégradations dues à la corrosion de leurs armatures ont été observées. Par ailleurs, l’action sismique provoque la fissuration des éléments de structure en béton armé, ce qui accélère la pénétration des ions chlorure et donc la corrosion des armatures, ce qui affecte la durée de vie et la sécurité de ces structures. Dans le cadre de cette recherche, nous présentons une analyse fiabiliste en fonction du temps d'un réservoir surélevé soumis à la corrosion par piqûres induite par la pénétration des ions de chlorure et à l’action sismique. Pour l'estimation de l’étendue de la corrosion des armatures dans les environnements contaminés par les chlorures, le modèle de Liu and Weyers est adopté.  La probabilité de défaillance de l’ouvrage est évaluée à l'aide des simulations de Monte Carlo. Les courbes de fragilité du réservoir en fonction du temps sont réalisées pour plusieurs accélérations sismiques, et pour différents taux d’agressivité de la corrosion.

A popular exposition in prose and verse of the Vimalakīrti Sūtra : an annotated translation of Stein manuscript number 4571
Creators: name: Salzberg, Stephan Marcus
Publisher: name: University of British Columbia
Year: 2010

description: This thesis consists of an annotated translation, with introduction, of a text recovered from Tun-huang, Stein manuscript number 4571. The text, dating from about 945 A.D., is of the genre called chianq-chinq-wen, texts used at religious gatherings, held twice yearly and lasting at least a week, at which lectures on a given Buddhist sutra were delivered for the benefit of a lay congregation. The text translated herein is one such lecture, covering the opening passages of the Vimalakirti Nirdesa Sutra (Wei-mo-chieh so-shuo ching), one of the more influential sutras in the history of Chinese Buddhism. The text partakes of the tripartate cyclical form characteristic of the genre: a chanted sutra portion, followed by a prose explanation or exposition, then by a relatively lengthy sung verse recapitulation which, in its final line, introduces the next sutra portion. The aim of the lecture lies less in scholarly explanation than in the fostering and reinforcement of certain religious attitudes through the narration and embellishment of the sutra passages. The translation, the first into any language, to the writer's knowledge, of a text in this genre, is accompanied by notes detailing, inter alia, discrepancies between the manuscript and the only printed edition of the text. The introduction describes the development and social context of the genre as well as the ceremonial setting of the lectures and their mode of performance. Various special features of the translated text are also discussed including the sources used and methods of adaptation.

Type:— INDONESIA. Sulawesi, Sulawesi Selatan, Latimojong, Palopo, Rantebala (cultivated at Bali Botanic Garden from living material collected in the wild), 16 May 2008, D.C. Thomas & W.H. Ardi 08-77 (holotype E!, isotype BO!).
Distribution:— Indonesia, endemic to Sulawesi, South Sulawesi: Latimojong Mountains (Fig. 1A).
Habitat:— Primary and disturbed hill rainforest, on rocky ground, between 1000 and 1500 m elevation.
Provisional IUCN conservation assessment:— Critically Endangered (CR) B1ab(iii), B2ab(iii). This species is known from only a few collections from the periphery of the Latimojong Forest Reserve. The collection localities are in forest patches close to human habitation and surrounded by land used for agricultural purposes (e.g. coffee plantations) and other severely disturbed forest vegetation. Exploration of various hill forest localities on the southern arm of Sulawesi have not resulted in any additional collections, and hence we must assume, until more extensive collection efforts reveal otherwise, that this species has a very restricted range. Because of the extremely small EOO and AOO in combination with observed disturbance and loss of forest habitat at the border of the Latimojong Forest Reserve we assess this species as Critically Endangered.
Additional specimens examined:— INDONESIA. Sulawesi. South Sulawesi: Todjamboe, 9 Feb. 1929, G.

Harmonic analysis of isotropic fields on the sphere with arbitrary masks

description: Obtaining constraints from the largest scales of a galaxy survey is challenging due to the survey mask allowing only partial measurement of large angular modes. This scatters information from the harmonic-space 2-point function away from the diagonal and introduces coupling between modes. In this paper, we derive a custom eigenbasis adapted to any particular survey geometry so that all information is retained on the diagonal. At the expense of a somewhat complex pixel- and selection-function-window, the result is a diagonal 2-point function with a simple shot noise, and a diagonal covariance matrix in the case of a Gaussian random field. We derive the basis on the surface of a sphere, and we use it to construct a 3D spherical Fourier-Bessel power spectrum estimator assuming a survey geometry that is separable in the angular and radial directions.

description: Linear, irreversible thermodynamics predicts that the entropy production rate can become negative. We demonstrate this prediction for metals under AC-driving whose conductivity is well-described by the Drude-Sommerfeld model. We then show that these negative rates are fully compatible with stochastic thermodynamics, namely, that the entropy production does fulfill a fluctuation theorem. The analysis is concluded with the observation that the stochastic entropy production as defined by the surprisal or ignorance of the Shannon information does not agree with the phenomenological approach.

description: Starting from the Mott insulator picture for cubic vanadates, we derive and investigate the model of superexchange interactions between V$^{3+}$ ions, with nearly degenerate $t_{2g}$ orbitals occupied by two electrons each. The superexchange interactions are strongly frustrated and demonstrate a strong interrelation between possible types of magnetic and orbital order. We elucidate the prominent role played by fluctuations of $yz$ and $xz$ orbitals which generate ferromagnetic superexchange interactions even in the absence of Hund's exchange. In this limit we find orbital valence bond state which is replaced either by $C$-type antiferromagnetic order with weak $G$-type orbital order at increasing Hund's exchange, or instead by $G$-type antiferromagnetic order when the lattice distortions stabilize $C$-type orbital order. Both phases are observed in YVO$_3$ and we argue that a dimerized $C$-type antiferromagnetic phase with stronger and weaker FM bonds alternating along the c axis may be stabilized by large spin-orbital entropy at finite temperature. This suggests a scenario which explains the origin of the exotic $C$-AF order observed in YVO$_3$ in the regime of intermediate temperatures and allows one to specify the necessary ingredients of a more complete future theory.

description: Despite the high durability level associated with reinforced concrete bridges, they are nonetheless susceptible to natural hazards and extreme events can impair their performance and serviceability throughout their lifespan. For that reason, maintenance, rehabilitation, and repair actions on existing structures are projected to rise and currently account for about 50% of the construction sector spending in most developed nations. To establish long-term maintenance schedules, it is vital to know the state of a structure and its degradation over time. Therefore, the monitoring of structures has become a necessary task to guarantee their use throughout their lifespan. Maintenance and inspection schemes depend on these systems that periodically or continuously collect information using chemical, optical, sound sensors, among others. However, the reliability of these sensors depends on environmental factors, durability, and even power outages. When any of these factors affect the sensors, their acquisition of information can be interrupted temporarily or permanently. This paper focuses on the competition of this missing data. The study uses one year of data from sensors monitoring a reinforced concrete structure that suffered interruptions in the acquisition processes. To reduce possible uncertainties that affect the analysis of the degradation of the materials and the reliability of the structures, the database of concrete electrical resistivity and concrete temperature of the sensors were analyzed, and time-series analysis method, artificial neural network models and generalized linear and non-linear models were used specifically to fill in the missing database values and perform predictions. Finally, the results are discussed, and recommendations are established for the application of this methodology for the analysis of the sensors used.

description: Weak entangled magnetic fields with mixed polarity occupy the main part of the quiet Sun. The Zeeman effect diagnostics fails to measure such fields because of cancellation in circular polarization. However, the Hanle effect diagnostics, accessible through the second solar spectrum, provides us with a very sensitive tool for studying the distribution of weak magnetic fields on the Sun. Molecular lines are very strong and even dominate in some regions of the second solar spectrum. The CN $B {}^{2} Σ- X {}^{2} Σ$ system is one of the richest and most promising systems for molecular diagnostics and well suited for the application of the differential Hanle effect method. The aim is to interpret observations of the CN $B {}^{2} Σ- X {}^{2} Σ$ system using the Hanle effect and to obtain an estimation of the magnetic field strength. We assume that the CN molecular layer is situated above the region where the continuum radiation is formed and employ the single-scattering approximation. Together with the Hanle effect theory this provides us with a model that can diagnose turbulent magnetic fields. We have succeeded in fitting modeled CN lines in several regions of the second solar spectrum to observations and obtained a magnetic field strength in the range from 10--30 G in the upper solar photosphere depending on the considered lines.

description: Road transport infrastructures have high strategic importance for nations’ economic and social development. Bridges are considered as critical assets for road network functionality i.e., any damage can have disastrous social repercussions. However, bridges are one of the most exposed assets; their deterioration can be attributed to material properties, load, and climatic factors, or catastrophic events. As a result, maintenance, rehabilitation, and repairs of existing structures account for about 50% of construction sector spending in most developed nations, and this percentage is projected to rise. Establishing a network-level budget and maintenance schedule is particularly complex due to the heterogeneity of bridge configurations and functions. Deterioration models are established in this sense to determine asset performance and cost-effective and efficient planned maintenance solutions to ensure continuous and correct operation. Markov chains are one of the most used models in this sense, i.e., to assess structure deterioration. The stochastic nature of Markov chains allows for taking into account the uncertainty of complex phenomena as well as their ease of application and compatibility. This study analyzed box beam and girder prestressed concrete bridges in the state of Indiana, U.S. Markov chains degradation models were implemented using National Bridge Inventory data of the last thirty-one years. Annual maintenance costs and budgets were established, and a genetic optimization algorithm was applied to determine the minimum annual maintenance cost for a period of eleven years. The results of the study demonstrate the contribution of the proposed methodology to ensure proper infrastructure maintenance and reduce costs.

description: Le gestionnaire du quai Hermann du Pasquier du port du Havre souhaite ausculter son ouvrage : en effet, cet ouvrage précontraint a subi des pertes de précontrainte et la résistance à la compression du béton est inconnue. Par ailleurs, les charges attendues sont en augmentation. Cette auscultation a été réalisée par inspection du béton et des aciers, ainsi que des essais destructifs sur prélèvements (fils d’acier et carottes de béton).


Des essais à l’arbalète ont permis d’estimer la tension résiduelle dans les câbles, qui a pu être analysée en termes de pertes : d’un côté, les pertes de précontrainte mesurées ont été comparées aux formules de l’Eurocode 2. De l’autre, leur caractère gaussien -proposé par le JCSS- a été testé. De plus, des essais de compression réalisés sur carottes ont permis de déterminer la résistance caractéristique à la compression telle qu’utilisée dans les calculs Eurocodes, tout en étudiant la variabilité de ses valeurs.


Cette évaluation d’un ouvrage existant aux Eurocodes a nécessité le recueil de données sur ouvrage. Les données recueillies ont été analysées statistiquement, et des valeurs ont dû être proposées pour les calculs déterministes (voire semi-probabilistes) réalisés par les bureaux d’étude.

description: We consider three-dimensional lattice SU(Nc) gauge theories with degenerate multicomponent (Nf>1) complex scalar fields that transform under the fundamental representation of the gauge SU(Nc) group and of the global U(Nf) invariance group, interacting with the most general quartic potential compatible with the global (flavor) and gauge (color) symmetries. We investigate the phase diagrams, identifying the low-temperature Higgs phases and their global and gauge symmetries, and the critical behaviors along the different transition lines. In particular, we address the role of the quartic scalar potential, which determines the Higgs phases and the corresponding symmetry-breaking patterns. Our study is based on the analysis of the minimum-energy configurations and on numerical Monte Carlo simulations. Moreover, we investigate whether some of the transitions observed in the lattice model can be related to the behavior of the renormalization-group flow of the continuum field theory with the same symmetries and field content around its stable charged fixed points. For Nc=2, numerical results are consistent with the existence of charged critical behaviors for Nf > Nf*, with 20 < Nf* < 40.

description: Cet article propose une approche innovante pour l'identification des désordres structuraux au sein des infrastructures de de génie civil, soumises aux excitations ambiantes stochastiques. L’ouvrage est modélisé par éléments finis, afin de permettre la création de la base de données, comprenant les rigidités aléatoires des éléments, d’une part, et les matrices de covariance correspondantes, d’autre part. Ces matrices de covariance sont calculées à partir de la réponse temporelle de la structure sous les conditions normales de trafic.


L’ensemble d’apprentissage permet l’entrainement du réseau de neurones, qui est composé de six couches convolutives suivies de deux couches totalement connectées. Etant entrainé et validé, ce réseau de neurones permet l’identification, la localisation et la quantification des désordres dans l’ouvrage.


La capacité prédictive du modèle est démontrée au moyen de l’analyse du pont de Longues au département du Puy-de-Dôme, sous différentes conditions de trafic et d’ampleur des désordres. Les résultats montrent le grand potentiel du modèle élaboré dans la surveillance de la santé structurale.

description: Civil engineering structures are essential to the infrastructure and directly impact people's lives and safety. Notably, many structures are in worrisome working conditions, with damage deterioration and occasionally collapse. Combining deep learning with structural health monitoring can provide unprecedented tools for structural damage detection and identification. This paper explores the use of acceleration features to predict the damage state of a structure using time-series acceleration data collected from the Phase I ASCE Structural Health Monitoring (SHM) benchmark model, where the primary identified damage is the removal of diagonal braces and beam connections. In this study, to overcome the limitations of using neural networks hampered by the small amount of data collected in shaker tests, three methods were used to encode time-series acceleration data as images, i.e., two-dimensional numerical matrix (2D Matrix), Short-Time Fourier Transform (STFT), and Wavelet Transform (WT). The encoded images were then used as input to the Convolutional Neural Networks (CNN) model. Two training/test scenarios are used to show the efficiency of the proposed method of structural damage recognition. The results show that the proposed method can predict structural damage and the WT combined with the CNN is the best approach regarding accuracy and efficiency.
