description: Singular limits of a class of evolutionary systems of partial differential equations having two small parameters and hence three time scales are considered. Under appropriate conditions solutions are shown to exist and remain uniformly bounded for a fixed time as the two parameters tend to zero at different rates. A simple example shows the necessity of those conditions in order for uniform bounds to hold. Under further conditions the solutions of the original system tend to solutions of a limit equation as the parameters tend to zero.

description: We report the discovery of a new bright quasar PHL 1811 as part of a followup program to identify bright quasars in the FIRST radio survey. With B=13.9, R=13.9, and z=0.192, this quasar is now the second brightest quasar (in apparent magnitude) known beyond z=0.1. Optically classified as a Narrow-line Seyfert 1 galaxy (NLS1), PHL 1811 is unusual for an object in this class in that it was not detected in X-rays in the ROSAT All Sky survey or in any previous X-ray survey. A follow-up BeppoSAX observation confirms that it is deficient in X-rays compared with other quasars, but poor signal to noise prevents a definitive characterization of the X-ray spectrum. We consider three alternative hypotheses to explain why PHL 1811 is a weak X-ray source: 1.) it is a BALQSO and suffers X-ray absorption; 2.) like several other luminous NLS1s, it exhibits high amplitude X-ray variability, and has been observed only when it is in an X-ray quiescent state; 3.) it is intrinsically weak because it simply lacks an X-ray emitting region.

description: This study explores a simple but strong baseline for person re-identification (ReID). Person ReID with deep neural networks has progressed and achieved high performance in recent years. However, many state-of-the-art methods design complex network structures and concatenate multi-branch features. In the literature, some effective training tricks briefly appear in several papers or source codes. The present study collects and evaluates these effective training tricks in person ReID. By combining these tricks, the model achieves 94.5% rank-1 and 85.9% mean average precision on Market1501 with only using the global features of ResNet50. The performance surpasses all existing global- and part-based baselines in person ReID. We propose a novel neck structure named as batch normalization neck (BNNeck). BNNeck adds a batch normalization layer after global pooling layer to separate metric and classification losses into two different feature spaces because we observe they are inconsistent in one embedding space. Extended experiments show that BNNeck can boost the baseline, and our baseline can improve the performance of existing state-of-the-art methods. Our codes and models are available at: https://github.com/michuanhaohao/reid-strong-baseline.

description: The outer giant planets, Uranus and Neptune, pose a challenge to theories of planet formation. They exist in a region of the Solar System where long dynamical timescales and a low primordial density of material would have conspired to make the formation of such large bodies ($\sim$ 15 and 17 times as massive as the Earth, respectively) very difficult. Previously, we proposed a model which addresses this problem: Instead of forming in the trans-Saturnian region, Uranus and Neptune underwent most of their growth among proto-Jupiter and -Saturn, were scattered outward when Jupiter acquired its massive gas envelope, and subsequently evolved toward their present orbits. We present the results of additional numerical simulations, which further demonstrate that the model readily produces analogues to our Solar System for a wide range of initial conditions. We also find that this mechanism may partly account for the high orbital inclinations observed in the Kuiper belt.

The Evolution of Adiabatic Supernova Remnants in a Turbulent, Magnetized Medium

description: (Abridged) We present the results of three dimensional calculations for the MHD evolution of an adiabatic supernova remnant in both a uniform and turbulent interstellar medium using the RIEMANN framework of Balsara. In the uniform case, which contains an initially uniform magnetic field, the density structure of the shell remains largely spherical, while the magnetic pressure and synchrotron emissivity are enhanced along the plane perpendicular to the field direction. This produces a bilateral or barrel-type morphology in synchrotron emission for certain viewing angles. We then consider a case with a turbulent external medium as in Balsara & Pouquet, characterized by $v_{A}(rms)/c_{s}=2$. Several important changes are found. First, despite the presence of a uniform field, the overall synchrotron emissivity becomes approximately spherically symmetric, on the whole, but is extremely patchy and time-variable, with flickering on the order of a few computational time steps. We suggest that the time and spatial variability of emission in early phase SNR evolution provides information on the turbulent medium surrounding the remnant. The shock-turbulence interaction is also shown to be a strong source of helicity-generation and, therefore, has important consequences for magnetic field generation. We compare our calculations to the Sedov-phase evolution, and discuss how the emission characteristics of SNR may provide a diagnostic on the nature of turbulence in the pre-supernova environment.

Here we show that only an AGN model predicting the formation of the broad Hb line emission in the wind of an accretion disk matches the observed 2-D variability pattern. Furthermore, we derive an improved mass of the central supermassive black hole of M = 1.0(+1.0,-0.5)E7 M_sun from the Hb velocity-delay map.

description: Coherent circulation rolls and their relevance for the turbulent heat transfer in a two-dimensional Rayleigh--Bénard convection model are analyzed. The flow is in a closed cell of aspect ratio four at a Rayleigh number ${\rm Ra}=10^6$ and at a Prandtl number ${\rm Pr}=10$. Three different Lagrangian analysis techniques based on graph Laplacians -- distance spectral trajectory clustering, time-averaged diffusion maps and finite-element based dynamic Laplacian discretization -- are used to monitor the turbulent fields along trajectories of massless Lagrangian particles in the evolving turbulent convection flow. The three methods are compared to each other and the obtained coherent sets are related to results from an analysis in the Eulerian frame of reference. We show that the results of these methods agree with each other and that Lagrangian and Eulerian coherent sets form basically a disjoint union of the flow domain. Additionally, a windowed time-averaging of variable interval length is performed to study the degree of coherence as a function of this additional coarse graining which removes small-scale fluctuations that cause trajectories to disperse quickly. Finally, the coherent set framework is extended to study heat transport.

title: The Development and Validation of the CAPS Model in a Reckless Behaviour Context: Identifying the Predictors of Unsafe Driving Behaviours
Creators: name: McNally, Brenton
Publisher: name: Griffith University
Year: 2014
Subjects: subject: Cognitive-Affective Personality System (CAPS)
subject: Young drivers
subject: Reckless behaviour

description: Young drivers have markedly higher motor vehicle crash-risk and crash involvement rates than do older drivers, and are severely over-represented in both morbidity and mortality rates related to vehicle crashes. Underpinning these findings is the tendency for young drivers to engage in more risk-taking whilst driving than older drivers. The current research focuses on unsafe driving behaviours. Unsafe driving behaviours satisfy Arnett’s (1992) three criteria of recklessness: they lack mainstream social approval and may even involve violations of the law; they carry strong connotations of negative consequences by placing drivers and/or their passengers at risk of morbidity, mortality, and other negative outcomes; and, by definition, they involve deliberate deviations from safe driving. Examples of these behaviours include speeding, tailgating, driving whilst using a mobile phone, driving whilst under the influence of alcohol and other psychoactive substances, and driving whilst tired or fatigued, all of which compromise both driving performance and driving safety. These are also more common amongst younger than older drivers. The current dissertation describes an application of Mischel and Shoda’s (1995) Cognitive-Affective Personality System (CAPS) to unsafe driving behaviours. CAPS is a meta-theoretical framework that fuses research from cognitive-social theory, as well as research on connectionism and activation. CAPS posits that personality consists of a mental representation comprised of a stable system of processes or dispositions, called Cognitive-Affective Units (CAUs), which mediate the relationship between features of the situation and subsequent behaviours. The CAPS model is distinctive in that it allows researchers to evaluate multiple, relevant predictors within a comprehensive, general framework and allows for the assessment of their inter-relations.

description: We have discovered an X-ray jet due to material ejected from the black hole X-ray transient XTE J1550-564. The discovery was first reported by Corbel et al. (Science, 298, 196 and astro-ph/0210224), and here, we present an analysis of the three Chandra observations made between 2000 June and 2000 September. For these observations, a source is present that moves in an eastward direction away from the point source associated with the compact object. The separation between the new source and the compact object changes from 21.3 arcseconds in June to 23.4 arcseconds in September, implying a proper motion of 21.2 +/- 7.2 mas/day, a projected separation of 0.31-0.85 pc and an apparent jet velocity between 0.34 +/- 0.12 and 0.93 +/- 0.32 times the speed of light for a source distance range of d = 2.8-7.6 kpc. These observations represent the first time that an X-ray jet proper motion measurement has been obtained for any accretion powered Galactic or extra-galactic source. While this work deals with the jet to the east of the compact object, the western jet has also been detected in the X-ray and radio bands. The most likely scenario is that the eastern jet is the approaching jet and that the jet material was ejected from the black hole in 1998. Along with a 1998 VLBI proper motion measurement, the Chandra proper motion indicates that the eastern jet decelerated between 1998 and 2000. We present results on the morphology and energy spectrum of the jet. We cannot definitively determine the X-ray emission mechanism, but a synchrotron origin is viable and may provide the simplest explanation for the observations.

Publisher: name: Griffith University

Subjects: subject: Leadership in teaching
subject: Subject teams in teaching

description: Over the last decade, it has become increasingly recognised that school leadership is critical for improved student outcomes. Hence, the spotlight is on leadership of teaching and learning, not only the learning of students, but also of professionals. Traditionally, leadership in schools has been associated with positional authority; the province of the principal. In recent years, it has been acknowledged that the capabilities of a single individual are inadequate for the many leadership roles and tasks in schools, including the challenge of preparing a diverse group of students for success in a post-industrial, knowledge-based world. Rather than associating leadership solely with the school principal, leadership is now also thought of as being distributed throughout the organisation across many talented actors (Gronn, 2002; Spillane, 2001; 2004). In addition to leading as individuals with responsibility and accountability for improving student outcomes, collaborating in subject teams is seen as a progressive way to lead teaching and learning. Subject teams are perceived to serve the function of learning communities where professionals collaborate and engage in dialogue about improving teaching and learning. One form of dialogue is advice and information – the building blocks of knowledge (Spillane, Healey, & Kim, 2010). Such knowledge is shared, not only in formal contexts, but also through informal networks; and is provided not only by formal leaders, but also by informal teacher leaders, as this study found.

We derive via perturbative expansions simple and accurate results for the case of an elliptical Gaussian window. Our results are applied to investigate the effect of beam ellipticity in the estimation of full-sky polarization correlation functions and the covariance matrix of power spectra. The relevance of this effect is also discussed by forecasting errors including beam asymmetry for current and future CMB experiments.

description: We demonstrate a compact all-fiber polarization-independent up-conversion single-photon detector based on integrated reverse proton exchanged periodically poled lithium niobate waveguides. The horizontally and vertically polarized components of randomly polarized signals are separated with a fiber-coupled polarization beam splitter, launched into two orthogonally polarized polarization maintaining fibers and fetched into two adjacent independent waveguides on the same device. The up-converted outputs from both waveguide channels are then combined with a multi-mode fiber combiner and detected by a silicon detector. With this configuration, the polarization-independent single-photon counting at 1.55 um is achieved with a system detection efficiency of 29.3%, a dark count rate of 1600 counts per second, and a polarization dependent loss of 0.1dB. This compact all-fiber system is robust and has great application potential in practical quantum key distribution systems.

description: Using a simplified model of cascade pair creation over pulsar polar caps presented in two previous papers, we investigate the expected gamma-ray output from pulsars' low altitude particle acceleration and pair creation regions. We divide pulsars into several categories, based on which mechanism truncates the particle acceleration off the polar cap, and give estimates for the expected luminosity of each category. We find that inverse Compton scattering above the pulsar polar cap provides the primary gamma rays which initiate the pair cascades in most pulsars. This reduces the expected $γ$-ray luminosity below previous estimates which assumed curvature gamma ray emission was the dominant initiator of pair creation in all pulsars.

description: This work shows the results of a research carried out in secondary school and university developing a co-disciplinary Research and Study Course (RSC) on questions connected to Physics and Mathematics in different groups. We present preliminary results of the RSC developed in three different groups: science education researchers, N=25 Mathematics teacher students (training teachers of Mathematics) at University, and N= 68 secondary school students. The development and scope of the RSC in each group is described by using the RSC components as defined by Chevallard’s Anthropological Theory of Didactics (ATD). Furthermore, a short description of the Praxeological Model of Reference is presented. This model was built by the researchers group in order to reply to the generative question, unknown in the beginning, and to anticipate and to conceive the evolution of the possible SRC in each institution. Some general results in each group are discussed and some conclusions concerning the ecology of the pedagogy of research and questioning the world at university and secondary schools are drawn.

description: This paper focuses on the theme of professional knowledge mobilized by teachers at elementary school in teaching sciences. This study was conducted in the context of the teaching of electricity in grade 5 and in grade 4 in France. It comes to analyzing teachers' knowledge acquisition mechanisms. The theoretical approach articulates science didactics and professional didactics as well as on a methodology that we developed specifically for this research. Unexpected events lead to a short regulation loop which allows the teacher to adjust his preparation. During this regulation, new professional knowledge is acquired. This study identifies some elements concerning the acquisition of professional experience.

description: We present new Hubble Space Telescope (HST) WFPC2 images of the post-starburst quasar UN J1025-0040, which contains both an active galactic nucleus (AGN) and a 400-Myr-old nuclear starburst of similar bolometric luminosity (10^{11.6} solar luminosities). The F450W and F814W images resolve the AGN from the starburst and show that the bulk of the star light (6 x 10^{10} solar masses) is contained within a central radius of about 600 parsecs, and lacks clear morphological structures at this scale. Equating the point-source light in each image with the AGN contribution, we determined the ratio of AGN-to-starburst light. This ratio is 69% in the red F814W image, consistent with our previous spectral analysis, but about 50% in the blue F450W image whereas we had predicted 76%. The HST images are consistent with previous photometry, ruling out variability (a fading AGN) as a cause for this result. We can explain the new data if there is a previously unknown young stellar population present, 40 Myr or younger, with as much as 10% of the mass of the dominant 400-Myr-old population. This younger starburst may represent the trigger for the current nuclear activity. The multiple starburst ages seen in UN J1025-0040 and its companion galaxy indicate a complex interaction and star-formation history.

description: The present study refers to second year (16-17 years old) upper secondary school students’ conceptions on elementary thermodynamics and especially the First Law of Thermodynamics (FLT). This paper focuses on students’ explanations of a real situation representing an adiabatic compression and their forms of reasoning in providing explanations. We used descriptive statistics and hierarchical cluster analysis in order to process students’ answers. The main results were that (a) the vast majority of the responses consisted of alternative frameworks, namely FLT is highly disregarded among the students, (b) the students provided confused explanations that entangle diverse physics models and/or referred to the phenomenology of the situation and (c) linear causal reasoning was the prevailing way for providing explanations, although it was inadequate for this physics level.

description: We report on an observing campaign in March 2001 to monitor the brightness of the later arriving Q0957+561 B image in order to compare with the previously published brightness observations of the (first arriving) A image. The 12 participating observatories provided 3543 image frames which we have analyzed for brightness fluctuations. From our classical methods for time delay determination, we find a 417.09 +/- 0.07 day time delay which should be free of effects due to incomplete sampling. During the campaign period, the quasar brightness was relatively constant and only small fluctuations were found; we compare the structure function for the new data with structure function estimates for the 1995--6 epoch, and show that the structure function is statistically non-stationary. We also examine the data for any evidence of correlated fluctuations at zero lag. We discuss the limits to our ability to measure the cosmological time delay if the quasar's emitting surface is time resolved, as seems likely.

description: Τhis paper aims at exploring children’s ideas concerning shadow formation as they are expressed through their drawings. A qualitative research approach was adopted using two sets of data (89 drawings in total) collected over a period of 6 months in two kindergartens, one in France and a second in Greece. The drawings in each group were realised using similar instructions defined jointly by the team of researchers. The indicators that were used to analyze the drawings can be aggregated in four categories: presence of the three entities needed to represent the phenomenon of shadow formation, shadow characteristics, alignment, and nature of light. Results are presented not with the intention of comparison of the two groups, but with the disposition of highlighting the diversity of categories that emerged. Findings and educational implications for science at kindergartens are thoroughly discussed.

Subjects: Avalanche, joint action theory for didactics (JATD), physics, resources, science communication

description: This paper presents a case study of a researcher in physics of granular matters who is explaining to a visitor the experimental research conducted in his lab. We consider the situation as a didactic transaction. We refer to the theoretical framework of the Joint Action Theory in Didactics, and of resources systems of teachers. The central data we analyze are videos shot during the visit. We collect data such as scientific productions of the researcher (posters, papers and thesis). We analyze how the researcher organizes resources, how he introduces knowledge in the ‘milieu’ to communicate his scientific activity and his results, to a public of non-science specialists. We show the relationship between didactic contract and didactic “milieu”, and we show their evolution in a very short episode.

Evidence For and Against Collimation of Gamma Ray Bursts
Creators: name: Rhoads, James E.
Publisher: name: arXiv
Year: 2001
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The degree to which gamma ray bursts are collimated is now the dominant uncertainty in their energy requirements and event rates. In this review I begin with the reasons for studying GRB collimation, then discuss existing tests for collimation and their applications to date, and finally outline some possible future tests. The most important conclusions are that (1) mean collimation angles much tighter than 1 degree appear ruled out; (2) the collimation angle appears to vary from burst to burst (like most other GRB properties). Some alternative explanations of apparent collimation signatures remain, but it should be possible to distinguish them from true collimation with future data sets and may be possible already. New satellites, improved followup observations, and new tests for collimation all promise continued rapid progress in coming years.

Long-distance entanglement in Motzkin and Fredkin spin chains

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We derive some entanglement properties of the ground states of two classes of quantum spin chains described by the Fredkin model, for half-integer spins, and the Motzkin model, for integer ones. Since the ground states of the two models are known analytically, we can calculate the entanglement entropy, the negativity and the quantum mutual information exactly. We show, in particular, that these systems exhibit long-distance entanglement, namely two disjoint regions of the chains remain entangled even when the separation is sent to infinity, i.e. these systems are not affected by decoherence. This strongly entangled behavior, occurring both for colorful versions of the models (with spin larger than 1/2 or 1, respectively) and for colorless cases (spin 1/2 and 1), is consistent with the violation of the cluster decomposition property. Moreover we show that this behavior involves disjoint segments located both at the edges and in the bulk of the chains.
