description: We have made the first detection of a near-infrared counterpart associated with the disk around Radio Source "I," a massive protostar in the Kleinmann-Low Nebula in Orion using imaging with laser guide star adaptive optics on the Keck II telescope. The infrared emission is evident in images acquired using L' (3.8 microns) and Ms (4.7 microns) filters and is not detectable at K' (2.1 microns). The observed morphology strongly suggests that we are seeing some combination of scattered and thermal light emanating from the disk. The disk is also manifest in the L'/Ms flux ratio image. We interpret the near-infrared emission as the illuminated surface of a nearly edge-on disk, oriented so that only the northern face is visible; the opposite surface remains hidden by the disk. We do not see infrared radiation associated directly with the star proposed to be associated with Source "I." The data also suggest that there is a cavity above and below the disk that is oriented perpendicular to the disk, and is sculpted by the known, strong outflow from the inner disk of Source I. We compare our data to models of a protostar with a surrounding disk, envelope, and wind-blown cavity in order to elucidate the nature of the disk around Radio Source I.

Amplitude death phenomena in delay--coupled Hamiltonian systems

description: Hamiltonian systems, when coupled {\it via} time--delayed interactions, do not remain conservative. In the uncoupled system, the motion can typically be periodic, quasiperiodic or chaotic. This changes drastically when delay coupling is introduced since now attractors can be created in the phase space. In particular for sufficiently strong coupling there can be amplitude death (AD), namely the stabilization of point attractors and the cessation of oscillatory motion. The approach to the state of AD or oscillation death is also accompanied by a phase--flip in the transient dynamics. A discussion and analysis of the phenomenology is made through an application to the specific cases of harmonic as well as anharmoniccoupled oscillators, in particular the Hénon-Heiles system.

Density-feedback control in traffic and transport far from equilibrium

Publisher: name: arXiv
Year: 2013
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: A bottleneck situation in one-lane traffic-flow is typically modelled with a constant demand of entering cars. However, in practice this demand may depend on the density of cars in the bottleneck. The present paper studies a simple bimodal realization of this mechanism to which we refer to as density-feedback control (DFC): If the actual density in the bottleneck is above a certain threshold, the reservoir density of possibly entering cars is reduced to a different constant value. By numerical solution of the discretized viscid Burgers equation a rich stationary phase diagram is found. In order to maximize the flow, which is the goal of typical traffic-management strategies, we find the optimal choice of the threshold. Analytical results are verified by computer simulations of the microscopic TASEP with DFC.

description: Accretion disks around very compact objects such as very massive Black hole can grow according to thick toroidal models. We face the problem of defining how does change the thickness of a toroidal accretion disk spinning around a Schwarzschild Black hole under the influence of a toroidal magnetic field and by varying the fluid angular momentum. We consider both an hydrodynamic and a magnetohydrodynamic disk based on the Polish doughnut thick model. We show that the torus thickness remains basically unaffected but tends to increase or decrease slightly depending on the balance of the magnetic, gravitational and centrifugal effects which the disk is subjected to.

Spectral monodromy of non selfadjoint operators
Creators: name: Phan, Quang Sang
Publisher: name: arXiv
Year: 2013
Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: We propose to build a combinatorial invariant, called the spectral monodromy, from the spectrum of a single non-selfadjoint h-pseudodifferential operator with two degrees of freedom in the semi-classical limit. Our inspiration comes from the quantum monodromy defined for the joint spectrum of an integrable system of n commuting selfadjoint h-pseudodifferential operators, given by S. Vu Ngoc. The first simple case that we treat in this work is a normal operator. In this case, the discrete spectrum can be identified with the joint spectrum of an integrable quantum system. The second more complex case we propose is a small perturbation of a selfadjoint operator with a classical integrability property. We show that the discrete spectrum (in a small band around the real axis) also has a combinatorial monodromy. The difficulty here is that we do not know the description of the spectrum everywhere, but only in a Cantor type set. In addition, we also show that the monodromy can be identified with the classical monodromy defined by J. Duistermaat.

description: On the basis of our general theoretical results developed previously in JETP 112, 246 (2011), we calculate the spatial distribution of atoms excited in a dense and cold atomic cloud by weak monochromatic light. We also study the atomic distribution over different Zeeman sublevels of the excited state in different parts of the cloud. The dependence of this distribution of atomic excitation on the density of the atomic ensemble and the frequency of external emission is investigated. We show that in the boundary regions of the cloud the orientation and alignment of atomic angular momentum takes place. Analysis of the spatial distribution of atomic excitation shows no noticeable signs of light localization effects even in those parameter regimes where the Ioffe-Regel criterium of strong localization is satisfied. However, comparative calculations performed in the framework of the scalar approximation to the dipole-dipole interaction reveals explicit manifestation of strong localization under some conditions.

A flexible algorithm for calculating pair interactions on SIMD architectures

Year: 2013

description: Calculating interactions or correlations between pairs of particles is typically the most time-consuming task in particle simulation or correlation analysis. Straightforward implementations using a double loop over particle pairs have traditionally worked well, especially since compilers usually do a good job of unrolling the inner loop. In order to reach high performance on modern CPU and accelerator architectures, single-instruction multiple-data (SIMD) parallelization has become essential. Avoiding memory bottlenecks is also increasingly important and requires reducing the ratio of memory to arithmetic operations. Moreover, when pairs only interact within a certain cut-off distance, good SIMD utilization can only be achieved by reordering input and output data, which quickly becomes a limiting factor. Here we present an algorithm for SIMD parallelization based on grouping a fixed number of particles, e.g. 2, 4, or 8, into spatial clusters. Calculating all interactions between particles in a pair of such clusters improves data reuse compared to the traditional scheme and results in a more efficient SIMD parallelization. Adjusting the cluster size allows the algorithm to map to SIMD units of various widths. This flexibility not only enables fast and efficient implementation on current CPUs and accelerator architectures like GPUs or Intel MIC, but it also makes the algorithm future-proof. We present the algorithm with an application to molecular dynamics simulations, where we can also make use of the effective buffering the method introduces.

description: Galaxy redshift surveys are a major tool to address the most challenging cosmological problems facing cosmology, like the nature of dark energy and properties dark matter. The same observations are useful for a much larger variety of scientific applications, from the study of small bodies in the solar system, to properties of tidal streams in the Milky Way halo, to galaxy formation and evolution. Here I briefly discuss what is a redshift survey and how it can be used to attack astrophysical and cosmological problems. I finish with a brief description of a new survey, the Javalambre Physics of the Accelerating Universe Astrophysical Survey (JPAS), which will use an innovative system of 56 filters to map ~8000 square degrees on the sky. JPAS photometric system, besides providing accurate photometric redshifts useful for cosmological parameter estimation, will deliver a low-resolution spectrum at each pixel on the sky, allowing for the first time an almost all-sky IFU science.

description: Many recent models consider the structure of individual interstellar medium (ISM) clouds as a way to explain observations of large parts of galaxies. To compare such models to observations, one must understand how to translate between surface densities observed averaging over large (~kpc) scales and surface densities on the scale of individual clouds (~pc scale), which are treated by models. We define a "clumping factor" that captures this translation as the ratio of the mass-weighted surface density, which is often the quantity of physical interest, to the area-weighted surface density, which is observed. We use high spatial resolution (sub-kpc) maps of CO and HI emission from nearby galaxies to measure the clumping factor of both atomic and molecular gas. The molecular and atomic ISM exhibit dramatically different degrees of clumping. As a result, the ratio H2/HI measured at ~kpc resolution cannot be trivially interpreted as a cloud-scale ratio of surface densities. HI emission appears very smooth, with a clumping factor of only ~1.3. Based on the scarce and heterogeneous high resolution data available, CO emission is far more clumped with a widely variable clumping factor, median ~7 for our heterogeneous data. Our measurements do not provide evidence for a universal mass-weighted surface density of molecular gas, but also cannot conclusively rule out such a scenario. We suggest that a more sophisticated treatment of molecular ISM structure, one informed by high spatial resolution CO maps, is needed to link cloud-scale models to kpc-scale observations of galaxies.

Effective noise channels for encoded quantum systems

description: We investigate effective noise channels for encoded quantum systems with and without active error correction. Noise acting on physical qubits forming a logical qubit is thereby described as a logical noise channel acting on the logical qubits, which leads to a significant decrease of the effective system dimension. This provides us with a powerful tool to study entanglement features of encoded quantum systems. We demonstrate this framework by calculating lower bounds on the lifetime of distillable entanglement and the negativity for encoded multipartite qubit states with different encodings. At the same time, this approach leads to a simple understanding of the functioning of (concatenated) error correction codes.

description: Der Einsatz von digitalen Medien im Mathematikunterricht eröffnet neue Möglichkeiten, Lernprozesse zu unterstützen. Insbesondere das Angebot und die Nutzung digitaler Assessment Tools rückt dabei vermehrt in den Fokus. Fachdidaktische Analysen ausgewählter, deutschsprachiger Angebote zeigen jedoch, dass überwiegend prozedurale Aufgaben bereitgestellt werden, Diagnosen nur auf Grundlage von Lösungsquoten (richtig/falsch) erfolgen und metakognitive Kompetenzen (z.B. durch Selbst-Assessments) nicht adressiert werden (Thurm & Graewert, 2022). Chancen, die digitales formatives Assessment an dieser Stelle bereithält (z.B. verstehensorientierte, interaktive Aufgabenformate zur Diagnose), werden kaum genutzt. Das Projekt BASE hat daher das Ziel, im Rahmen eines Design-Based-Research Ansatzes ein verstehensorientiertes digitales Selbst-Assessment-Tool (BASETool) zum arithmetischen Basiswissen zu entwickeln und zu beforschen. Im Fokus steht dabei die Frage, wie automatisiertes Feedback zum Selbst-Assessment das konzeptuelle Wissen und die Selbst Assessmentkompetenzen von Lernenden beeinflusst. In dem vorliegenden Beitrag sollen die Konzeption des BASE-Tools sowie Ergebnisse aus einer ersten Erprobung vorgestellt werden. Die Erprobung wurde durch die folgende Forschungsfrage geleitet:  Welche Potenziale und welche Hindernisse ergeben sich für Lernende beim Arbeiten mit dem BASE-Tool?

description: Our research focus on gravitational collapse of electrically charged scalar field in dilaton gravity and in the presence of phantom coupling. We examine dynamical behaviour of the scalar field coupled to Maxwell field when gravitational interactions have form consistent with the low-energy limit of the string theory. Moreover, we allow the evolving fields to have negative sign in front of the respective kinetic term of the Lagrangian. The main aim of our studies is to investigate in what manner does the phantom nature of either Maxwell or dilaton fields (or both of them) affect the outcomes of the collapse. It turns out that the influence is crucial to the obtained spacetime structures. Negative kinetic energy of one (or both) of the fields delays, changes the course or even prevents the collapse.

description: To systematically review the available randomized controlled trials in the literature concerning the application of virtual reality (VR) rehabilitation interventions compared to conventional physical therapy, in regaining the upper limb motor function among patients with chronic stroke. A systematic electronic database search was conducted for related studies published from inauguration and until June 25, 2020 in nine databases. Another new search was done on February 1, 2021 and no new studies were identified. Six studies were included in the analysis. Significant improvement was seen following the VR therapy in patients with chronic stroke, compared to their scores prior to it (SMD = 0.28; 95% CI = 0.03–0.53; p = .03). There was neither heterogeneity (I2 = 0% and P = .5) nor a risk of bias (P = .8) among the included studies. VR interventions produced a comparable effectiveness to that of the conventional rehabilitation, with no statistically significant difference (SMD = 0.15; 95% CI = −0.14–0.44; P = .3). There was neither heterogeneity (I2 = 40% and P = .1) nor a risk of bias (P = .5) among the included studies. The upper limb motor function of patients with chronic stroke who underwent VR-based rehabilitative intervention showed significant improvement as compared to the pre-treatment state. Our analysis also revealed no superiority of VR interventions over conservative therapies; however, the difference observed did not accomplish statistical significance.

The Asymptotics of Multiple Optimal Stopping Times
Creators: name: Entwistle, Hugh
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: We consider optimal stopping problems, in which a sequence of independent random variables is drawn from a known continuous density and are sequentially observed, with no recall of previous observations. The objective of such problems is to find a procedure which maximizes the expected reward. We first present a methodology for obtaining asymptotic expressions for the expectation and variance of the single optimal stopping time as the number of drawn variables becomes large. We then extend these results to the multiple stopping problem where the objective is now to maximize the expected reward, which is the sum of all variables stopped on. For a family of distributions with exponential tails and for the uniform distribution, we provide the complete generalisation of the multiple stopping problem by computing the inductive behaviour of the stopping time. Explicit calculations are provided for several common probability density functions as well as numerical simulations to support our asymptotic predictions.
Bipartite bound entanglement in continuous variables through deGaussification

description: We introduce a class of bipartite entangled continuous variable states that are positive under partial transposition operation, i.e., PPT bound entangled. These states are based on realistic preparation procedures in optical systems, being thus a feasible option to generate and observe genuinely bipartite bound entanglement in high precision experiments. One fundamental step in our scheme is to perform a non-Gaussian operation over a single-mode Gaussian state; this deGaussification procedure is achieved through a modified single-photon addition, which is a procedure that has currently being investigated in diverse optical setups. Although dependent on a single-photon detection in a idler channel, the preparation can be made unconditional after a calibration of the apparatus. The detection and proof of bound entanglement is made by means of the Range Criterion, theory of Hankel operators and Gerschgorin Disk s perturbation theorems.

description: Now a days, a new family of web applications open applications, are emerging (e.g., Social Networking, News and Blogging). Generally, these open applications are non-confidential. The security needs of these applications are only client/server authentication and data integrity. For securing these open applications, effectively and efficiently, HTTPI, a new transport protocol is proposed, which ensures the entire security requirements of open applications. Benefit of using the HTTPI is that it is economical in use, well-suited for cache proxies, like HTTP is, and provides security against many Internet attacks (Server Impersonation and Message Modification) like HTTPS does. In terms of performance HTTPI is very close to the HTTP, but much better than HTTPS. A Web service is a method of communication between two ends over the Internet. These web services are developed over XML and HTTP. Today, most of the open applications use web services for most of their operations. For securing these web services, security design based on HTTPI is proposed. Our work involves securing the web services over SOAP, based on the HTTPI. This secure web service might be applicable for open applications, where authentication and integrity is needed, but no confidentiality required. In our paper, we introduce a web service security model based on HTTPI protocol over SOAP and develop a preliminary implementation of this model. We also analyze the performance of our approach through an experiment and show that our proposed approach provides higher throughput, lower average response time and lower response size than HTTPS based web service security approach.

description: This work investigates the diffusion of cooperative behavior over time in a decentralized cognitive radio network with selfish spectrum-sensing users. The users can individually choose whether or not to participate in cooperative spectrum sensing, in order to maximize their individual payoff defined in terms of the sensing false-alarm rate and transmit energy expenditure. The system is modeled as a partially connected network with a statistical distribution of the degree of the users, who play their myopic best responses to the actions of their neighbors at each iteration. Based on this model, we investigate the existence and characterization of Bayesian Nash Equilibria for the diffusion game. The impacts of network topology, channel fading statistics, sensing protocol, and multiple antennas on the outcome of the diffusion process are analyzed next. Simulation results that demonstrate how conducive different network scenarios are to the diffusion of cooperation are presented for further insight, and we conclude with a discussion on additional refinements and issues worth pursuing.

description: Studying the scattering of excitations around a dynamical background has a long history in the context of integrable models. The Gubser-Klebanov-Polyakov string solution provides such a background for the string/gauge correspondence. Taking the conjectured all-loop asymptotic equations for the AdS_4/CFT_3 correspondence as the starting point, we derive the S-matrix and a set of spectral equations for the lowest-lying excitations. We find that these equations resemble closely the analogous equations for AdS_5/CFT_4, which are also discussed in this paper. At large values of the coupling constant we show that they reproduce the Bethe equations proposed to describe the spectrum of the low-energy limit of the AdS_4xCP^3 sigma model.

description: Polarization de-multiplexing and multiplexing by means of conical refraction is proposed to increase the channel capacity for free space optical communication applications. The proposed technique is based on the forward-backward optical transform occurring when a light beam propagates consecutively along the optic axes of two identical biaxial crystals with opposite orientations of their conical refraction characteristic vectors. We present experimental proof of usefulness of the conical refraction de-multiplexing and multiplexing technique by increasing in one order of magnitude the channel capacity at optical frequencies in a propagation distance of 4m.

description: Nickel islands are grown on W(110) at elevated temperatures. Islands with a thickness of two layers are investigated with scanning tunneling microscopy. Spectroscopic measurements reveal that nanometer sized areas of the islands exhibit distinctly different apparent heights and dI/dV spectra. Spin polarized and paramagnetic band structure calculations indicate that the spectral features are due to fcc(111) and bcc(110) orientations of the Ni film, respectively.

Supplementary file - When the News Report Women: Media and Gender Gap in Political Interest
Creators: name: Sanchez Vitores, Irene
Publisher: name: figshare
Year: 2023
Subjects: Gender and politics

description: Media plays a prominent role in shaping individuals' declared levels of political interest, but its role regarding gender differences remains largely unexplored. To what extent are media contents and their reflection of gender roles related to declared levels of political interest in men and women? This article argues that more egalitarian media environments, where a larger share of women are represented, should associate with smaller gender differences in political interest. Data from the European Social Survey and the Global Media Monitoring Programme have been merged to test this argument. Results suggest that more women being reported show some association with more minor differences between men's and women’s declared levels of political interest. This difference is particularly present when the increase occurs in more hard-news-oriented media like the printed press, in topics such as economic affairs or when being quoted as experts, which are traditionally identified as more masculinized.
On estimation of mean squared errors of benchmarked empirical Bayes estimators

Year: 2013
Subjects: subject: Methodology (stat.ME)

description: We consider benchmarked empirical Bayes (EB) estimators under the basic area-level model of Fay and Herriot while requiring the standard benchmarking constraint. In this paper we determine the excess mean squared error (MSE) from constraining the estimates through benchmarking. We show that the increase due to benchmarking is O(m^{-1}), where m is the number of small areas. Furthermore, we find an asymptotically unbiased estimator of this MSE and compare it to the second-order approximation of the MSE of the EB estimator or, equivalently, of the MSE of the empirical best linear unbiased predictor (EBLUP), that was derived by Prasad and Rao (1990). Morever, using methods similar to those of Butar and Lahiri (2003), we compute a parametric bootstrap estimator of the MSE of the benchmarked EB estimator under the Fay-Herriot model and compare it to the MSE of the benchmarked EB estimator found by a second-order approximation. Finally, we illustrate our methods using SAIPE data from the U.S. Census Bureau, and in a simulation study.
Mechanical and electrical properties of CNT/Cu composites fabricated by spark plasma sintering

Subjects: Other education not elsewhere classified

description: Spark plasma sintering was used to fabricate CNT/Cu MMCs, with increasing CNT content (0.05, 0.25, 0.5 and 1 wt%) in each sample. A novel dispersion method was utilised to coat milled Cu particles with SiO2 nanoparticles and CNTs ready for sintering. SiO2 nanoparticles increased surface area for enhanced CNT dispersion and attachment. CNT clustering was evident with increased CNT content amongst Cu particles. Sintered samples showed larger CNT filled pores with increasing CNT concentrations. Microhardness peaked at 0.5 wt% CNTs (61.19 HV), increasing 12% in contrast to pure Cu. The peak electrical conductivity was measured at pure Cu (49.8 MS/m) and drops significantly with the addition of increasing CNT content (41.2, 39.8, 33, 30.2 MS/m), respectively. The drop in electrical conductivity is mostly attributed to increased CNT agglomeration and enlarged pore size which cause electron and phonon scattering. Relative densities greater than 90% were measured, indicating less than 10% porosity was achieved. Successful dispersion of CNTs was possible up to 0.5 wt% CNT through the novel dispersion technique. Pure Cu is best chosen for maximum electrical conductivity while 0.5 wt% CNT is best for increased surface hardness.
A comparative analysis of transcription factor expression during metazoan embryonic development

description: During embryonic development, a complex organism is formed from a single starting cell. These processes of growth and differentiation are driven by large transcriptional changes, which are following the expression and activity of transcription factors (TFs). This study sought to compare TF expression during embryonic development in a diverse group of metazoan animals: representatives of vertebrates (Danio rerio, Xenopus tropicalis), a chordate (Ciona intestinalis) and invertebrate phyla such as insects (Drosophila melanogaster, Anopheles gambiae) and nematodes (Caenorhabditis elegans) were sampled, The different species showed overall very similar TF expression patterns, with TF expression increasing during the initial stages of development. C2H2 zinc finger TFs were over-represented and Homeobox TFs were under-represented in the early stages in all species. We further clustered TFs for each species based on their quantitative temporal expression profiles. This showed very similar TF expression trends in development in vertebrate and insect species. However, analysis of the expression of orthologous pairs between more closely related species showed that expression of most individual TFs is not conserved, following the general model of duplication and diversification. The degree of similarity between TF expression between Xenopus tropicalis and Danio rerio followed the hourglass model, with the greatest similarity occuring during the early tailbud stage in Xenopus tropicalis and the late segmentation stage in Danio rerio. However, for Drosophila melanogaster and Anopheles gambiae there were two periods of high TF transcriptome similarity, one during the Arthropod phylotypic stage at 8-10 hours into Drosophila development and the other later at 16-18 hours into Drosophila development.

description: We begin by giving a description of the radio-frequency generator-cavity-beam coupled system in terms of basic quantities. Taking beam loading and cavity detuning into account, expressions for the cavity impedance as seen by the generator and as seen by the beam are derived. Subsequently methods of beam-loading compensation by cavity detuning, radio-frequency feedback and feedforward are described. Examples of digital radio-frequency phase and amplitude control for the special case of superconducting cavities are also given. Finally, a dedicated phase loop for damping synchrotron oscillations is discussed.
