description: The quantum to classical transition maybe caused by decoherence or by dynamical collapse of the wave-function. We propose quantum discord as a tool, 1) for comparing and contrasting the role of a collapse model (Continuous Spontaneous Localization) and various sources of decoherence (environmental and fundamental), 2) for detecting collapse model and fundamental decoherence for an experimentally demonstrated macroscopic entanglement. We discuss the experimental times which will lead to the detection of either Continuous Spontaneous Localization or fundamental decoherence. We further put bounds on the collapse parameters from this experiment for quantum discord.

Measurement of the inclusive jet cross section in pp collisions at sqrt(s) = 2.76 TeV
Creators: name: CMS Collaboration
Publisher: name: arXiv
Year: 2015
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: The double-differential inclusive jet cross section is measured as a function of jet transverse momentum pT and absolute rapidity y, using proton-proton collision data collected with the CMS experiment at the LHC, at a center-of-mass energy of sqrt(s) = 2.76 TeV and corresponding to an integrated luminosity of 5.43 inverse picoboarns. Jets are reconstructed within the pT range of 74 to 592 GeV and the rapidity range |y| < 3.0. The reconstructed jet spectrum is corrected for detector resolution. The measurements are compared to the theoretical prediction at next-to-leading-order QCD using different sets of parton distribution functions. This inclusive cross section measurement explores a new kinematic region and is consistent with QCD predictions.

Fast formation of isogeometric Galerkin matrices by weighted quadrature

Publisher: name: arXiv
Year: 2016
Subjects: subject: Numerical Analysis (math.NA)
subject: FOS: Mathematics

description: In this paper we propose an algorithm for the formation of matrices of isogeometric Galerkin methods. The algorithm is based on three ideas. The first is that we perform the external loop over the rows of the matrix. The second is that we calculate the row entries by weighted quadrature. The third is that we exploit the (local) tensor product structure of the basis functions. While all ingredients have a fundamental role for computational efficiency, the major conceptual change of paradigm with respect to the standard implementation is the idea of using weighted quadrature: the test function is incorporated in the integration weight while the trial function, the geometry parametrization and the PDEs coefficients form the integrand function. This approach is very effective in reducing the computational cost, while maintaining the optimal order of approximation of the method. Analysis of the cost is confirmed by numerical testing, where we show that, for $p$ large enough, the time required by the floating point operations is less than the time spent in unavoidable memory operations (the sparse matrix allocation and memory write). The proposed algorithm allows significant time saving when assembling isogeometric Galerkin matrices for all the degrees of the test spline space and paves the way for a use of high-degree $k$-refinement in isogeometric analysis.

description: We establish a precise relation between mixed boundary conditions for scalar fields in asymptotically anti de Sitter spacetimes and the equation of state of the dual fluid. We provide a detailed derivation of the relation in the case of five bulk-dimensions for scalar fields saturating the Breitenlohner-Freedman bound. As a concrete example, we discuss the five dimensional scalar-tensor theories describing a constant speed of sound.

description: We detect the kinematic Sunyaev-Zel'dovich (kSZ) effect with a statistical significance of $4.2 σ$ by combining a cluster catalogue derived from the first year data of the Dark Energy Survey (DES) with CMB temperature maps from the South Pole Telescope Sunyaev-Zel'dovich (SPT-SZ) Survey. This measurement is performed with a differential statistic that isolates the pairwise kSZ signal, providing the first detection of the large-scale, pairwise motion of clusters using redshifts derived from photometric data. By fitting the pairwise kSZ signal to a theoretical template we measure the average central optical depth of the cluster sample, $\barτ_e = (3.75 \pm 0.89)\cdot 10^{-3}$. We compare the extracted signal to realistic simulations and find good agreement with respect to the signal-to-noise, the constraint on $\barτ_e$, and the corresponding gas fraction. High-precision measurements of the pairwise kSZ signal with future data will be able to place constraints on the baryonic physics of galaxy clusters, and could be used to probe gravity on scales $ \gtrsim 100$ Mpc.

description: Multidisciplinary design optimization methods aim at adapting numerical optimization techniques to the design of engineering systems involving multiple disciplines. In this context, a large number of mixed continuous, integer and categorical variables might arise during the optimization process and practical applications involve a large number of design variables. Recently, there has been a growing interest in mixed variables constrained Bayesian optimization but most existing approaches severely increase the number of the hyperparameters related to the surrogate model. In this paper, we address this issue by constructing surrogate models using less hyperparameters. The reduction process is based on the partial least squares method. An adaptive procedure for choosing the number of hyperparameters is proposed. The performance of the proposed approach is confirmed on analytical tests as well as two real applications related to aircraft design. A significant improvement is obtained compared to genetic algorithms.

description: Improving the capabilities of detecting faint X-ray sources is fundamental to increase the statistics on faint high-z AGN and star-forming galaxies. We performed a simultaneous Maximum Likelihood PSF fit in the [0.5-2] keV and [2-7] keV energy bands of the 4 Ms{\em Chandra} Deep Field South (CDFS) data at the position of the 34930 CANDELS H-band selected galaxies. For each detected source we provide X-ray photometry and optical counterpart validation. We validated this technique by means of a raytracing simulation. We detected a total of 698 X-ray point-sources with a likelihood $\mathcal{L}$$>$4.98 (i.e. $>$2.7$σ$). We show that the prior knowledge of a deep sample of Optical-NIR galaxies leads to a significant increase of the detection of faint (i.e. $\sim$10$^{-17}$ cgs in the [0.5-2] keV band) sources with respect to "blind" X-ray detections. By including previous X-ray catalogs, this work increases the total number of X-ray sources detected in the 4 Ms CDFS, CANDELS area to 793, which represents the largest sample of extremely faint X-ray sources assembled to date. Our results suggest that a large fraction of the optical counterparts of our X-ray sources determined by likelihood ratio actually coincides with the priors used for the source detection. Most of the new detected sources are likely star-forming galaxies or faint absorbed AGN. We identified a few sources sources with putative photometric redshift z$>$4. Despite the low number statistics and the uncertainties on the photo-z, this sample significantly increases the number of X--ray selected candidate high-z AGN.

description: The geodesics prescription in holographic approach in Lorentzian signature is valid only for geodesics which connect spacelike-separated points at the boundary, since there are no timelike geodesics which reach the boundary. There is also no straightforward analytic Euclidean continuation for a general background, such as e. g. moving particle in AdS. We propose an improved geodesic image method for two-point Lorentzian correlators which is valid for arbitrary time intervals in case of the bulk spacetime deformed by point particles. We illustrate that our prescription is consistent with the case when the analytic continuation exists and with the quasigeodesics prescription used in previous work. We also discuss some other applications of the improved image method, such as holographic entanglement entropy and multiple particles in AdS3.

description: (1) Part I deals with flow of perfect fluid past the Grid for d/2c = 1/2 and for d/2c=2/3-, ie, with the solution of ▿ψ=0. Electrical analogy is applied to check the approximate solution obtained. Increase of electrical resistance of a plate of uniform thickness due to the presence of circular hole is obtained from theory and experiment. A method of estimating the increased velocity of flow past cylinder due to interference is given based on perfect fluid motion. (2) Part II deals with the arithmetical solution of viscous flow past the Grid d/2c =1/2 at Reynold's Number 20 There does not seem to exist a stationary eddy pair at this Reynold's Number. This is confirmed by photographing the wake of the cylinder of the Grid. (cf, case of Single Cylinder) Values of Kp, Kv and K"D are obtained from the above solution and are found to be higher than those for a single cylinder in infinite field at the same Reynold's Number. (3) Part III deals with the solution of Boundary Layer equation for the Grid d/2c = 1/2 at R = 85I The viscous drag coefficient Kv for a cylinder of the Grid d/2c = I/2 is found to be 2,4I/?R (4) Part IV gives an approximate estimate of the front generator pressure of a Cylinder of the Grid d/2c =I/2 based on Boundary Layer Theory. This is found to be greater than that for a single cylinder. Approximate estimate of this for the Grid d/2c = I/2 is also given from the experimental pressure curves. (5) Part VI deals with experiments. Pressure drag is calculated from pressure measurements round a Cylinder of the Grid d/2c = I/2. Total drags of a Cylinder of the Grid d/2c = I/2 and d/2c =3/I0 are obtained from direct force measurements. Total drag of Cylinder od the Grid d/2c = I/2 is also obtained by measuring the loss in total head. The drag coefficients are found to be greater than those for a single cylinder in infinite field. The viscous drag coefficient Kv for a cylinder of the Grid d/2c = I/2 as obtained from the experiments is found to be 3/√R as compared to 2/√R for single cylinder. (6) Part VII deals with the Karman Vortex Street behind the Grid. It is found to be unstable. (7) In Part VIII, the writer uses Rosenhead and Scwabe's particulars of Karman street behind a cylinder between channel walls to estimate the total drag coefficients for a clinder of Grid for different values of d/2c. (8) In Part IX an approximate expression for the total drag the ratio of the total drag coefficients of a cylinder of the Grid or for a cylinder between parallel walls to that of a cylinder in infinite field is given. (9) In Part X an alternative expression for the increased velocity of flow past cylinder due to interference, is given based on the increased drag coefficients. (10) In Part XI an approximate estimate of the Increased drag of a cylinder between channel walls, when the velocity distribution is parabolic is given.

description: Motivated by the formal argument that a non-zero shear modulus is the result of averaging over a constrained configurations space, we demonstrate that the shear modulus calculated over a range of temperatures and averaging times can be expressed (relative to its infinite frequency value) as a single function of the mean squared displacement. This result is shown to hold for both a glass-liquid and a crystal-liquid system.

description: Since high microbiological loads in water pipes of medical facilities and dental units pose a risk for human health, the establishment of bactericide agents should be advanced to minimize the contamination level. We focused on the efficacy of plasma-activated water (PAW) as a novel disinfectant against waterborne microorganisms being present in medical in-house and dental unit water-lines (DUWL), considering a dilution effect of PAW when flushing the water bearing systems. The efficiency of PAW, activated under defined conditions (90 W for 30 min) in a lab unit, was studied towards eight different waterborne species focusing on 'Pseudomonas aeruginosa, Acinetobacter' spp. and 'Legionella' spp. present in water-lines. PAW, presenting low pH at < 3.2 and high oxidation-reduction potential (763 mV) and conductivity (963 μS/cm) values, was applied in defined units to determine the minimum volume amount added to water for bacterial reduction. Six species failed in growth when exposed to the double PAW volume unit after 30 min incubation. A fivefold volume excess provided sufficient activity to inactivate the waterborne microorganisms while only 'Acinetobacter baumannii' required a tenfold PAW surplus substantially reduction. Microorganisms show a species-specific susceptibility to PAW and cell count reduction strikingly correlates with added PAW volumes. PAW needs to be used in excess to achieve adequate cell reduction in aqueous environments, considering that dilution effects always accompany the disinfection. Our results indicate that PAW is a suitable disinfecting agent in a watery environment applicable for microbiological reduction in DUWLs.

description: We find that the purifications of several Gaussian maximally mixed states (GMMSs) correspond to some Gaussian maximally entangled states (GMESs) in the continuous-variable regime. Here, we consider a two-mode squeezed vacuum (TMSV) state as a purification of the thermal state and construct a general formalism of the Gaussian purification process. Moreover, we introduce other kind of GMESs via the process. All of our purified states of the GMMSs exhibit Gaussian profiles; thus, the states show maximal quantum entanglement in the Gaussian regime.

description: Micro/Nano Electro Mechanical Systems (MEMS/NEMS) provide the engineer with a powerful set of solutions to a wide variety of technical challenges. However, because they are mechanical systems, response times can be a limitation. In some situations, advanced engineered drive techniques can improve response times by as much as a thousand, significantly opening up the application space for MEMS/NEMS solutions.

description: We review recent developments in nonlinear quantum transport through nanostructures and mesoscopic systems driven by thermal gradients or in combination with voltage biases. Low-dimensional conductors are excellent platforms to analyze both the thermoelectric and heat dynamics beyond linear response because due to their small size a small temperature difference applied across regions gives rise to large thermal biases. We offer a theoretical discussion based on the scattering approach to highlight the differences between the linear and the nonlinear regimes of transport. We discuss recent experiments on quantum dots and molecular junctions subjected to strong temperature differences. Theoretical predictions concerning the Kondo effect and heat rectification proposals are briefly examined. An important issue is the calculation of thermoelectric efficiencies including nonlinearities. Cross Seebeck effects and nonlinear spin filtering arise in superconductors and topological insulators while mixed noises between charge and heat currents are also considered. Finally, we provide an outlook on the possible future directions of the field.

description: Modern large-scale scientific discovery requires multidisciplinary collaboration across diverse computing facilities, including High Performance Computing (HPC) machines and the Edge-to-Cloud continuum. Integrated data analysis plays a crucial role in scientific discovery, especially in the current AI era, by enabling Responsible AI development, FAIR, Reproducibility, and User Steering. However, the heterogeneous nature of science poses challenges such as dealing with multiple supporting tools, cross-facility environments, and efficient HPC execution. Building on data observability, adapter system design, and provenance, we propose MIDA: an approach for lightweight runtime Multi-workflow Integrated Data Analysis. MIDA defines data observability strategies and adaptability methods for various parallel systems and machine learning tools. With observability, it intercepts the dataflows in the background without requiring instrumentation while integrating domain, provenance, and telemetry data at runtime into a unified database ready for user steering queries. We conduct experiments showing end-to-end multi-workflow analysis integrating data from Dask and MLFlow in a real distributed deep learning use case for materials science that runs on multiple environments with up to 276 GPUs in parallel. We show near-zero overhead running up to 100,000 tasks on 1,680 CPU cores on the Summit supercomputer.

description: Element abundances in high-redshift quasar absorbers offer excellent probes of the chemical enrichment of distant galaxies, and can constrain models for population III and early population II stars. Recent observations indicate that the sub-damped Lyman-alpha (sub-DLA) absorbers are more metal-rich than DLA absorbers at redshifts 0$$4.7. However, only 3 DLAs at $z$$>$4.5 and none at $z$$>$3.5 have "dust-free" metallicity measurements of undepleted elements. We report the first quasar sub-DLA metallicity measurement at $z$$>$3.5, from detections of undepleted elements in high-resolution data for a sub-DLA at $z$=5.0. We obtain fairly robust abundances of C, O, Si, and Fe, using lines outside the Lyman-alpha forest. This absorber is metal-poor, with O/H]=-2.00$\pm$0.12, which is $\gtrsim$4$σ$ below the level expected from extrapolation of the trend for $z$$

description: Simulation studies of the atomic shear stress in the local potential energy minima (inherent structures) are reported for binary liquid mixtures in 2D and 3D. These inherent structure stresses are fundamental to slow stress relaxation and high viscosity in supercooled liquids. We find that the atomic shear stress in the inherent structures (IS) of both liquids at rest exhibits slowly decaying anisotropic correlations. We show that the stress correlations contributes significantly to the variance of the total shear stress of the IS configurations and consider the origins of the anisotropy and spatial extent of the stress correlations.

description: Materials with a perfect kagome lattice structure of magnetic ions are intensively sought for, because they may exhibit exotic ground states like the a quantum spin liquid phase. Barlowite is a natural mineral that features perfect kagome layers of copper ions. However, in barlowite there are also copper ions between the kagome layers, which mediate strong interkagome couplings and lead to an ordered ground state. Using {\it ab initio} density functional theory calculations we investigate whether selective isoelectronic substitution of the interlayer copper ions is feasible. After identifying several promising candidates for substitution we calculate the magnetic exchange couplings based on crystal structures predicted from first-principles calculations. We find that isoelectronic substitution with nonmagnetic ions significantly reduces the interkagome exchange coupling. As a consequence, interlayer-substituted barlowite can be described by a simple two-parameter Heisenberg Hamiltonian, for which a quantum spin liquid ground state has been predicted.

Το σύνδρομο Sjogren, η IgG4 σχετιζόμενη σιαλαδενίτιδα και οι ANCA σχετιζόμενες αγγειίτιδες αντιπροσωπεύουν τις σημαντικότερες αυτοάνοσες καταστάσεις των σιελογόνων αδένων. Ταυτόχρονα θα αναφερθεί και η σαρκοείδωση, καθώς , αν και επίσημα αποτελεί χρόνια φλεγμονώδη-κοκκιωματώδη νόσο άγνωστης αιτιολογίας, υπάρχουν αρκετά δεδομένα που να υποστηρίζουν την αυτοάνοση αιτιολογία της νόσου. Εξαιτίας έλλειψης ειδικών συμπτωμάτων, η διάγνωση αυτών των καταστάσεων παραμένει πρόκληση για τον κλινικό ιατρό.
description: Salivary glands are frequent sites of manifestations of autoimmune disorders in the head and neck. Sjogren’s syndrome, IgG4 related disease and ΑΝCA related vasculitides represent the most important autoimmune salivary gland disorders. Sarcoidosis, although officially considered a chronic inflammatory-granulomatous condition of unknown etiology, will also be briefly examined in this paper, because there is enough data to support the hypothesis that it is an immune mediated disease. Due to the lack of specific symptoms, diagnosis of these conditions remains a challenge.

description: We provide several Tauberian theorems for Laplace transforms with local pseudofunction boundary behavior. Our results generalize and improve various known versions of the Ingham-Fatou-Riesz theorem and the Wiener-Ikehara theorem. Using local pseudofunction boundary behavior enables us to relax boundary requirements to a minimum. Furthermore, we allow possible null sets of boundary singularities and remove unnecessary uniformity conditions occurring in earlier works; to this end, we obtain a useful characterization of local pseudofunctions. Most of our results are proved under one-sided Tauberian hypotheses; in this context, we also establish new boundedness theorems for Laplace transforms with pseudomeasure boundary behavior. As an application, we refine various results related to the Katznelson-Tzafriri theorem for power series.

description: In this paper we present the results of numerical simulations intended to study the behavior of non-Abelian cosmic strings networks. In particular we are interested in discussing the variations in the asymptotic behavior of the system as we variate the number of generators for the topological defects. A simple model which should generate cosmic strings is presented and its lattice discretization is discussed. The evolution of the generated cosmic string networks is then studied for different values for the number of generators for the topological defects. Scaling solution appears to be approached in most cases and we present an argument to justify the lack of scaling for the residual cases.
