description: Novel magnetic phases are expected to occur in highly frustrated spin systems. Here we study the structurally perfect kagomé antiferromagnet CdCu$_3$(OH)$_6$(NO$_3$)$_2\cdot$H$_2$O by magnetization, magnetic torque, and heat capacity measurements using single crystals.An antiferromagnetic order accompanied by a small spontaneous magnetization that surprisingly is confined in the kagomé plane sets in at $T_\mathrm{N}\approx$4 K, well below the nearest-neighbor exchange interaction $J / k_B$ = 45 K.This suggests that a unique $\bf q = 0$ type 120$^\circ$ spin structure with "negative" (downward) vector chirality, which breaks the underlying threefold rotational symmetry of the kagomé lattice and thus allows a spin canting within the plane, is exceptionally realized in this compound rather than a common one with "positive" (upward) vector chirality. The origin is discussed in terms of the Dzyaloshinskii-Moriya interaction.

Harnessing Flexible and Reliable Demand Response Under Customer Uncertainties

description: Demand response (DR) is a cost-effective and environmentally friendly approach for mitigating the uncertainties in renewable energy integration by taking advantage of the flexibility of customers' demands. However, existing DR programs suffer from either low participation due to strict commitment requirements or not being reliable in voluntary programs. In addition, the capacity planning for energy storage/reserves is traditionally done separately from the demand response program design, which incurs inefficiencies. Moreover, customers often face high uncertainties in their costs in providing demand response, which is not well studied in literature. This paper first models the problem of joint capacity planning and demand response program design by a stochastic optimization problem, which incorporates the uncertainties from renewable energy generation, customer power demands, as well as the customers' costs in providing DR. We propose online DR control policies based on the optimal structures of the offline solution. A distributed algorithm is then developed for implementing the control policies without efficiency loss. We further offer enhanced policy design by allowing flexibilities into the commitment level. We perform real world trace based numerical simulations. Results demonstrate that the proposed algorithms can achieve near optimal social costs, and significant social cost savings compared to baseline methods.

description: LSI +61 303 is one of the few X-ray binaries with a Be star companion from which radio, X-rays and high-energy gamma-ray (GeV and TeV) emission have been observed. The nature of the high energy activity of the system is not yet fully understood, but it is widely believed that it is generated due to the interaction of the relativistic electrons leaving the compact object with the photons and non-relativistic wind of the Be star. The superorbital variability of the system has been observed in the radio, optical and X-ray domains and could be due to the cyclic change of the Be star disk size. In this paper we systematically review all publicly available data from Suzaku, XMM-Newton, Chandra and Swift observatories in order to measure the absorption profile of the circumstellar Be disk as a function of orbital and superorbital phases. We also discuss short-term variability of the system, found during the analysis and its implications for the understanding of the physical processes in this system.

description: We calculate the beam function for longitudinally-polarized quarks through next-to-next-to-leading order (NNLO) in QCD perturbation theory. This is the last missing ingredient needed to apply the factorization theorem for the $N$-jettiness event-shape variable in polarized collisions through the NNLO level. We present all technical details of our derivation. As a by-product of our calculation we provide the first independent check of the previously-obtained unpolarized quark beam function. We anticipate that our result will have phenomenological applications in describing data from polarized collisions.

Convergence of Stochastic Approximation Monte Carlo and modified Wang-Landau algorithms: Tests for the Ising model

description: We investigate the behavior of the deviation of the estimator for the density of states (DOS) with respect to the exact solution in the course of Wang-Landau and Stochastic Approximation Monte Carlo (SAMC) simulations of the two-dimensional Ising model. We find that the deviation saturates in the Wang-Landau case. This can be cured by adjusting the refinement scheme. To this end, the 1/t-modification of the Wang-Landau algorithm has been suggested. A similar choice of refinement scheme is employed in the SAMC algorithm. The convergence behavior of all three algorithms is examined. It turns out that the convergence of the SAMC algorithm is very sensitive to the onset of the refinement. Finally, the internal energy and specific heat of the Ising model are calculated from the SAMC DOS and compared to exact values.
FRB as Products of Accretion Disc Funnels

Year: 2017
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: The repeating FRB 121102, the only FRB with an accurately determined position, is associated with a variable persistent radio source consistent with a low luminosity active galactic nucleus. I suggest that FRB originate in the accretion disc funnels of intermediate mass black holes. Narrowly collimated radiation is emitted along the wandering instantaneous angular momentum axis of accreted matter. We observe this emission as a fast radio burst when it sweeps across the direction to the observer. This model constrains the mass of the black hole to values below those of galactic nuclei. It predicts, in contrast to neutron star (pulsar or SGR) models, that repeating FRB will not be periodic and will be co-located with persistent but variable radio sources resulting from the off-axis emission. The model is analogous, on smaller spatial, lower mass and accretion rate and shorter temporal scales, to AGN making double radio sources, with FRB corresponding to blazars in which the jets point toward us.

Numerical simulation of artificial microswimmers driven by Marangoni flow

Year: 2017
Subjects: subject: Computational Physics (physics.comp-ph)
subject: FOS: Physical sciences

description: In the present paper the behavior of a single artificial microswimmer is addressed, namely an active droplet moving by Marangoni flow. The non-uniform surface tension distribution underlying the propulsion mechanism of the droplet, is generated by a non-uniform distribution of surfactant on its surface. We provide a numerical treatment for the main factors playing a role in real systems, such as advection, diffusion and the presence of chemical species with different behaviors. The flow field inside and outside the droplet is derived, thus accounting for the two-way coupling between the surrounding fluid and the motion of the swimmer. Mass diffusion is also taken into account. In particular, we consider two concentration fields: the surfactant concentration in the bulk, i.e. in the liquid surrounding the droplet, and the surfactant concentration on the surface. The latter is related to the local surface tension, through an equation of state (Langmuir equation). We examine different interaction mechanisms between the bulk and the surface concentration fields, namely the case of insoluble surfactants attached to the surface (no exchange between the bulk and the surface) and soluble surfactants with adsorption/desorption at the surface. We also consider the case where the bulk concentration field is in equilibrium with the content of the droplet. The numerical results are validated through comparison with analytical calculations. We show that our model can reproduce the typical pusher/puller behavior presented by squirmers. It is also able to capture the self-propulsion mechanism of droplets driven by Belousov-Zhabotinsky (BZ) reactions, as well as a typical chemotactic behavior.

description: During the work, model of a stationary axial seven-stage compressor of the K -50 type was gradually developed: a rotor with transverse and longitudinal grooves, impeller blades with different types of shanks, guide devices of various types of attachment to the housing, a casing including suction and discharge chambers, as well as bearing mounting covers. Then the parts were printed on a 3D printer for further assembly and operation in the educational process. During the development process, the problems of interfacing parts, correct selection of gaps, installation of parts on a 3D printer machine for high-quality printing, as well as the logic of the design from the point of view of technological manufacturing were solved.

Magnetars in Ultra-Long Gamma-Ray Bursts

description: Supernova 2011kl, associated with the ultra-long gamma-ray burst (ULGRB) 111209A, exhibited a higher-than-normal peak luminosity, placing it in the parameter space between regular supernovae and super-luminous supernovae. Its light curve can only be matched by an abnormally high fraction of $^{56}$Ni that appears inconsistent with the observed spectrum, and as a result it has been suggested that the supernova, and by extension the gamma-ray burst, are powered by the spin-down of a highly magnetised millisecond pulsar, known as a magnetar. We investigate the broadband observations of ULGRB 111209A, and find two independent measures that suggest a high density circumburst environment. However, the light curve of the GRB afterglow shows no evidence of a jet break (the steep decline that would be expected as the jet slows due to the resistance of the external medium) out to three weeks after trigger, implying a wide jet. Combined with the high isotropic energy of the burst, this implies that only a magnetar with a spin period of ~ 1 ms or faster can provide enough energy to power both ULGRB 111209A and Supernova 2011kl.

description: This paper introduces Surgical Data Science as an emerging scientific discipline. Key perspectives are based on discussions during an intensive two-day international interactive workshop that brought together leading researchers working in the related field of computer and robot assisted interventions. Our consensus opinion is that increasing access to large amounts of complex data, at scale, throughout the patient care process, complemented by advances in data science and machine learning techniques, has set the stage for a new generation of analytics that will support decision-making and quality improvement in interventional medicine. In this article, we provide a consensus definition for Surgical Data Science, identify associated challenges and opportunities and provide a roadmap for advancing the field.

Index coding with erroneous side information

Publisher: name: arXiv
Year: 2017
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: In this paper, new index coding problems are studied, where each receiver has erroneous side information. Although side information is a crucial part of index coding, the existence of erroneous side information has not yet been considered. We study an index code with receivers that have erroneous side information symbols in the error-free broadcast channel, which is called an index code with side information errors (ICSIE). The encoding and decoding procedures of the ICSIE are proposed, based on the syndrome decoding. Then, we derive the bounds on the optimal codelength of the proposed index code with erroneous side information. Furthermore, we introduce a special graph for the proposed index coding problem, called a $δ_s$-cycle whose properties are similar to those of the cycle in the conventional index coding problem. Properties of the ICSIE are also discussed in the $δ_s$-cycle and clique. Finally, the proposed ICSIE is generalized to an index code for the scenario having both additive channel errors and side information errors, called a generalized error correcting index code (GECIC).

description: For the measurement of the electric dipole moment of protons and deuterons, a novel waveguide RF Wien filter has been designed and will soon be integrated at the COoler SYnchrotron at Jülich. The device operates at the harmonic frequencies of the spin motion. It is based on a waveguide structure that is capable of fulfilling the Wien filter condition ($\vec{E} \perp \vec{B}$) \textit{by design}. The full-wave calculations demonstrated that the waveguide RF Wien filter is able to generate high-quality RF electric and magnetic fields. In reality, mechanical tolerances and misalignments decrease the simulated field quality, and it is therefore important to consider them in the simulations. In particular, for the electric dipole moment measurement, it is important to quantify the field errors systematically. Since Monte-Carlo simulations are computationally very expensive, we discuss here an efficient surrogate modeling scheme based on the Polynomial Chaos Expansion method to compute the field quality in the presence of tolerances and misalignments and subsequently to perform the sensitivity analysis at zero additional computational cost.

description: Les accidents de la route font partie des principales causes de mortalité chez les jeunes dans le monde. En France, la motorisation des déplacements se répercute sur la mobilité des enfants et retarde le développement d’une expérience approfondie de la marche et des déplacements à vélo. Les connaissances des règles de sécurité liées aux déplacements piétons, cyclistes ou en voiture sont assimilées tôt chez les enfants. Pourtant ils ne respectent pas les règles apprises et ont des difficultés à généraliser leurs connaissances en matière de sécurité. Les comportements s’améliorent avec l’âge mais restent insuffisants. Le premier objectif de l’article est donc de fournir une revue de la littérature internationale sur les compétences de sécurité et les prises de risque des enfants selon une approche psycho-socio-développementale. Le second objectif est de faire un état des lieux des actions éducatives qui visent à améliorer les comportements des enfants en vue de baisser l’accidentalité des enfants sur la route. Après avoir présenté, dans une première partie le développement des compétences de mobilité chez l’enfant avec l’âge, le rôle des caractéristiques individuelles sur les conduites à risque sera abordé dans une deuxième partie. La troisième partie expose le poids des pratiques parentales sur les comportements des enfants. Enfin, une dernière partie propose une analyse des pistes éducatives qui cherchent à développer les connaissances des enfants, leur compréhension des règles et des situations, ainsi qu’à améliorer leurs compétences sur la route.

description: Objectif : L’exposition aux nuisances liées au trafic routier telles que le bruit, la pollution de l’air, les accidents de la route peut conduire à une gêne ou à un sentiment d’insécurité routière. La gêne est définie comme un sentiment de déplaisir associé à un agent ou une condition connu ou reconnu par un individu ou un groupe comme les affectant négativement, diminuant leur qualité de vie à long terme. L’insécurité routière est, quant à elle, reconnue comme affectant le bien-être. L’objectif de cette étude était d’identifier les déterminants (sociodémographiques, socioéconomiques, relatifs à la mobilité quotidienne) de la gêne liée au bruit, à la pollution de l’air, et du sentiment d’insécurité routière. Méthodes : 720 sujets, âgés de 18 ans et plus, vivant dans le département du Rhône (France) en 2013 ont été interrogés via un questionnaire soumis par téléphone. La gêne et le sentiment d’insécurité routière ont été estimés via une échelle en 10 points allant de 1 (pas gêné(e)) à 10 (fortement gêné(e)) pour chacune des nuisances, avec un seuil à 8. Résultats : Notre étude a révélé principalement que les usagers des modes doux sont ceux qui déclarés ressentir la plus forte gêne, et ce, quelle que soit la nuisance, comparé aux usagers des modes motorisés. Conclusions : Les moins polluants sont les plus gênés. Ces résultats sont vraiment intéressants. Les usagers des modes doux contribuent à une amélioration de la qualité de l’air, une réduction de la congestion du trafic et du risque d’accidents de la route, tout en améliorant la santé des populations. Dans un contexte de promotion des modes doux, ces usagers devraient être protégés contre une telle gêne, susceptible d’entraver le développement d’une telle pratique.

description: Individual, luminescent point defects in solids so called color centers are atomic-sized quantum systems enabling sensing and imaging with nanoscale spatial resolution. In this overview, we introduce nanoscale sensing based on individual nitrogen vacancy (NV) centers in diamond. We discuss two central challenges of the field: First, the creation of highly-coherent, shallow NV centers less than 10 nm below the surface of single-crystal diamond. Second, the fabrication of tip-like photonic nanostructures that enable efficient fluorescence collection and can be used for scanning probe imaging based on color centers with nanoscale resolution.

description: In the new era of large-scale astronomical surveys, automated methods of analysis and classification of bulk data are a fundamental tool for fast and efficient production of deliverables. This becomes ever more imminent as we enter the Gaia era. We investigate the potential detectability of eclipsing binaries with Gaia using a data set of all Kepler eclipsing binaries sampled with Gaia cadence and folded with the Kepler period. The performance of fitting methods is evaluated with comparison to real Kepler data parameters and a classification scheme is proposed for the potentially detectable sources based on the geometry of the light curve fits. The polynomial chain (polyfit) and two-Gaussian models are used for light curve fitting of the data set. Classification is performed with a combination of the t-SNE (t-distrubuted Stochastic Neighbor Embedding) and DBSCAN (Density-Based Spatial Clustering of Applications with Noise) algorithms. We find that approximately 68% of Kepler Eclipsing Binary sources are potentially detectable by Gaia when folded with the Kepler period and propose a classification scheme of the detectable sources based on the morphological type indicative of the light curve, with subclasses that reflect the properties of the fitted model (presence and visibility of eclipses, their width, depth, etc.).

description: Entanglement is a unique quantum mechanical attribute and a fundamental resource of quantum technologies. Entanglement can be achieved in various individual degrees of freedom, nonetheless some systems are able to create simultaneous entanglement in multiple degrees of freedom - hyper-entanglement. A hyper-entangled state of light represents a valuable tool capable of reducing the experimental requirements and resource overheads and it can improve the success rate of quantum information protocols. Here, we report on demonstration of polarization and time-bin hyper-entangled photons emitted from a single quantum dot. We achieved this result by applying resonant and coherent excitation on a quantum dot system with marginal fine structure splitting. Our results yield fidelities to the maximally entangled state of 0.81(6) and 0.87(4) in polarization and time-bin, respectively.

title: When feeling matter: Power increases reliance on subjective experiences
Creators: name: Weick, Mario
Publisher: name: University of Kent

description: Subjective experiences importantly contribute to the situated nature of human cognition and play a central role in guiding behaviour and judgments. However, past research on power focused exclusively on declarative knowledge, while the role of subjective experiences has been neglected. Focusing on the informational function of subjective experiences, nine experimental studies tested the assumption that power increases reliance on subjective experiences as a source of information in judgments and decision making. Study 1 was correlational and found a link between power and self-reported reliance on experiences. Studies 2 to 5 used the ease-of-retrieval paradigm (Schwarz et ak, 1991) to separate the contributions of declarative knowledge and subjective experiences to individuals’ judgments. Across a variety of targets such as attitudes, self-perception, and stereotyping, and using different operationalizations of power including priming, trait-dominance, and actual power in managerial contexts, these studies showed that power consistently increased reliance on subjective experiences. Moreover, one study was longitudinal and showed that subjective experiences can have long-term effects and thereby contribute to judgmental stability. A sixth study confirmed the hypothesis that reliance on subjective experiences only provide powerful, but not for powerless individuals with a sense of certainty in their judgments. Finally, Studies 7 to 9 explored boundary conditions, showing that power does not necessarily always strengthen the impact of subjective experiences. Taken together, the present research confirmed the hypothesis that power increases reliance on subjective experiences, and it highlights implications for judgmental stability and the ways individuals derive a sense of certainty in their judgments. The results also showed that powerful individuals are flexible perceivers and do not necessarily always draw on subjective experiences. These findings contrast with previous research that has focused on declarative information and the expression of core attitudes and prior knowledge. The present research supports an emerging perspective whereby power leads to greater flexibility in judgments and decisions.
Discriminating Cascading Processes in Nonlinear Optics; A QED Analysis Based on Their Molecular and Geometric Origin

description: The nonlinear optical response of a system of molecules often contains contributions whereby the products of lower-order processes in two separate molecules give signals that appear on top of a genuine direct higher-order process with a single molecule. These many-body contributions are known as cascading and complicate the interpretation of multidimensional stimulated Raman and other nonlinear signals. In a quantum electrodynamic (QED) treatment, these cascading processes arise from second-order expansion in the molecular coupling to vacuum modes of the radiation field, i.e., single-photon exchange between molecules, which also gives rise to other collective effects. We predict the relative phase of the direct and cascading nonlinear signals and its dependence on the microscopic dynamics as well as the sample geometry. This phase may be used to identify experimental conditions for distinguishing the direct and cascading signals by their phase. Higher-order cascading processes involving the exchange of several photons between more than two molecules are discussed as well.

description: We have expanded upon earlier work that investigates the relative importance of coronal loops with isothermal $versus$ multithermal cross-field temperature distributions. These results are important for determining if loops have substructure in the form of unresolved magnetic strands. We have increased the number of loops targeted for temperature analysis from 19 to 207 with the addition of 188 new loops from multiple regions. We selected all loop segments visible in the 171-Å images of the Atmospheric Imaging Assembly (AIA) that had a clean background. 86 of the new loops were rejected because they could not be reliably separated from the background in other AIA filters. 61 loops required multithermal models to reproduce the observations. 28 loops were effectively isothermal, that is, the plasma emission to which AIA is sensitive could not be distinguished from isothermal emission, within uncertainties. 10 loops were isothermal. Also part of our inventory were one small flaring loop, one very cool loop whose temperature distribution could not be constrained by the AIA data, and one loop with inconclusive results. Our survey can confirm an unexpected result from the pilot study: we found no isothermal loop segments where we could properly use the 171-to-193 ratio method, which would be similar to the analysis done for many loops observed with TRACE and EIT. We recommend caution to observers who assume the loop plasma is isothermal, and hope that these results will influence the direction of coronal heating models and the efforts modelers spend on various heating scenarios.

description: Acoustic glitches are regions inside a star where the sound speed or its derivatives change abruptly. These leave a small characteristic oscillatory signature in the stellar oscillation frequencies. With the precision achieved by {\it Kepler} seismic data, it is now possible to extract these small amplitude oscillatory signatures, and infer the locations of the glitches. We perform glitch analysis for all the 66 stars in the {\it Kepler} seismic LEGACY sample to derive the locations of the base of the envelope convection zone and the helium ionization zone. The signature from helium ionization zone is found to be robust for all stars in the sample, whereas the convection zone signature is found to be weak and problematic, particularly for relatively massive stars with large errorbars on the oscillation frequencies. We demonstrate that the helium glitch signature can be used to constrain the properties of the helium ionization layers and the helium abundance.

description: We propose a simple method of combined synchronous modulations to generate the analytically exact solutions for a parity-time symmetric two-level system. Such exact solutions are expressible in terms of simple elementary functions and helpful for illuminating some generalizations of appealing concepts originating in the Hermitian system. Some intriguing physical phenomena, such as stabilization of a non-Hermitian system by periodic driving, non-Hermitian analogs of coherent destruction of tunneling (CDT) and complete population inversion (CPI), are demonstrated analytically and confirmed numerically. In addition, by using these exact solutions we derive a pulse area theorem for such non-Hermitian CPI in the parity-time symmetric two-level system. Our results may provide an additional possibility for pulse manipulation and coherent control of the parity-time symmetric two-level system.

description: We use state-of-the-art, three-dimensional non-local thermodynamic equilibrium (non-LTE) radiative magnetohydrodynamic simulations of the quiet solar atmosphere to carry out detailed tests of chromospheric magnetic field diagnostics from free-free radiation at millimeter and submillimeter wavelengths (mm/submm). The vertical component of the magnetic field was deduced from the mm/submm brightness spectra and the degree of circular polarization synthesized at millimeter frequencies. We used the frequency bands observed by the Atacama Large Millimeter/Submillimeter Array (ALMA) as a convenient reference. The magnetic field maps obtained describe the longitudinal magnetic field at the effective formation heights of the relevant wavelengths in the solar chromosphere. The comparison of the deduced and model chromospheric magnetic fields at the spatial resolution of both the model and current observations demonstrates a good correlation, but has a tendency to underestimate the model field. The systematic discrepancy of about 10 percent is probably due to averaging of the restored field over the heights contributing to the radiation, weighted by the strength of the contribution. On the whole, the method of probing the longitudinal component of the magnetic field with free-free emission at mm/submm wavelengths is found to be applicable to measurements of the weak quiet-Sun magnetic fields. However, successful exploitation of this technique requires very accurate measurements of the polarization properties (primary beam and receiver polarization response) of the antennas, which will be the principal factor that determines the level to which chromospheric magnetic fields can be measured. Consequently, high-resolution and high-precision observations of circularly polarized radiation at millimeter wavelengths can be a powerful tool for producing chromospheric longitudinal magnetograms.

description: Cet article présente des résultats issus du projet de recherche RETMIF (Réduction des émissions du transport de marchandises, scénarios pour l’Île-de-France, 2013-2015) financé par l’ADEME/AACT-AIR, dont l’objectif était de comprendre l’évolution des zones à émissions réduites européennes, et plus particulièrement leur impact sur le transport de marchandises, afin d’en tirer des enseignements qui pourraient servir à la mise en place d’une ZER en région parisienne. Les « zones à émissions réduites » (ZER) sont des parties d’une ville dont l’accès est réservé aux véhicules les moins polluants. Elles sont connues en Europe sous le vocable Low Emission Zones et ont désormais en France le nom de « zones à circulation restreinte » (ZCR) depuis l’adoption de la loi pour la transition énergétique de 2015. Avec plus de 200 d’entre elles déjà opérationnelles, les ZER font désormais partie des principales solutions mises en œuvre par les villes européennes pour améliorer la qualité de l’air. La question de leurs impacts sur la qualité de l’air est traitée par la littérature mais celle de leurs impacts socio-économiques sur le secteur professionnel du transport de marchandises l’est peu. C’est pourquoi nous avons entrepris, par une méthodologie originale, quantitative et qualitative, d’identifier les conséquences pour les activités des entreprises de transport de la mise en place de ZER déjà établies depuis plusieurs années. Nous avons choisi les exemples de Londres, Berlin et Göteborg. Deux approches ont été développées : d’une part, la collecte de données quantitatives sur le secteur du transport de marchandises ; et des entretiens auprès de différents acteurs (autorités locales, fédérations de transporteurs et entreprises de transport) d’autre part. L’analyse de ces données permet de conclure de la façon suivante : la mise en place d’une ZER semble réduire le nombre d’entreprises de transport livrant en ville ; et cette réduction permet aux acteurs – publics et privés – à agir pour sa modernisation. Celle-ci est nécessaire car ce secteur connaît aujourd’hui beaucoup de dysfonctionnements, tant environnementaux du fait de l’utilisation encore importante de véhicules anciens, que sociaux, du fait d’un grand nombre de très petites entreprises ayant des difficultés à maintenir une rentabilité minimale. Les ZER représentent une réponse structurelle favorisant la réorganisation du secteur du transport de marchandises en ville.
