description: In this work, we explore finite-dimensional linear representations of nonlinear dynamical systems by restricting the Koopman operator to an invariant subspace. The Koopman operator is an infinite-dimensional linear operator that evolves observable functions of the state-space of a dynamical system [Koopman 1931, PNAS]. Dominant terms in the Koopman expansion are typically computed using dynamic mode decomposition (DMD). DMD uses linear measurements of the state variables, and it has recently been shown that this may be too restrictive for nonlinear systems [Williams et al. 2015, JNLS]. Choosing nonlinear observable functions to form an invariant subspace where it is possible to obtain linear models, especially those that are useful for control, is an open challenge. Here, we investigate the choice of observable functions for Koopman analysis that enable the use of optimal linear control techniques on nonlinear problems. First, to include a cost on the state of the system, as in linear quadratic regulator (LQR) control, it is helpful to include these states in the observable subspace, as in DMD. However, we find that this is only possible when there is a single isolated fixed point, as systems with multiple fixed points or more complicated attractors are not globally topologically conjugate to a finite-dimensional linear system, and cannot be represented by a finite-dimensional linear Koopman subspace that includes the state. We then present a data-driven strategy to identify relevant observable functions for Koopman analysis using a new algorithm to determine terms in a dynamical system by sparse regression of the data in a nonlinear function space [Brunton et al. 2015, arxiv]; we show how this algorithm is related to DMD. Finally, we demonstrate how to design optimal control laws for nonlinear systems using techniques from linear optimal control on Koopman invariant subspaces.

description: The nearby, middle-aged PSR B1055-52 has many properties in common with the Geminga pulsar. Motivated by the Geminga's enigmatic and prominent pulsar wind nebula (PWN), we searched for extended emission around PSR B1055-52 with Chandra ACIS. For an energy range 0.3-1 keV, we found a 4 sigma flux enhancement in a 4.9-20 arcsec annulus around the pulsar. There is a slight asymmetry in the emission close, 1.5-4 arcsec, to the pulsar. The excess emission has a luminosity of about 10^{29} erg s^{-1} in an energy range 0.3-8 keV for a distance of 350 pc. Overall, the faint extended emission around PSR B1055-52 is consistent with a PWN of an aligned rotator moving away from us along the line of sight with supersonic velocity, but a contribution from a dust scattering halo cannot be excluded. Comparing the properties of other nearby, middle-aged pulsars, we suggest that the geometry -- the orientations of rotation axis, magnetic field axis, and the sight-line -- is the deciding factor for a pulsar to show a prominent PWN. For PSR B1055-52, we also report on a flux decrease of at least 30% between the 2000 XMM-Newton and our 2012 Chandra observation. We tentatively attribute this flux decrease to a cross-calibration problem, but further investigations of the pulsar are required to exclude actual intrinsic flux changes.

description: The Pauli exclusion principle is one of the most fundamental manifestations of quantum statistics. Here, we report on its local observation in a spin-polarized degenerate gas of fermions in an optical lattice. We probe the gas with single-site resolution using a new generation quantum gas microscope avoiding the common problem of light induced losses. In the band insulating regime, we measure a strong local suppression of particle number fluctuations and a low local entropy per atom. Our work opens a new avenue for studying quantum correlations in fermionic quantum matter both in and out of equilibrium.

description: We investigate the inactive-active phase transition in an array of additive (exclusive-or) cellular automata under noise. The model is closely related with the Domany-Kinzel probabilistic cellular automaton, for which there are rigorous as well as numerical estimates on the transition probabilities. Here we characterize the critical behavior of the noisy additive cellular automaton by mean field analysis and finite-size scaling and show that its phase transition belongs to the directed percolation universality class of critical behavior. As a by-product of our analysis, we argue that the critical behavior of the noisy elementary CA 90 and 102 (in Wolfram's enumeration scheme) must be the same. We also perform an empirical investigation of the mean field equations to assess their quality and find that away from the critical point (but not necessarily very far away) the mean field approximations provide a reasonably good description of the dynamics of the PCA.

description: Excerpts from the report Introduction: Reliable classification of cotton requires that samples be adequately representative of the bales from which they are drawn. The manner of drawing the sample and other factors affecting its representativeness deserve more consideration than they have received. The importance of a properly drawn sample is too little recognized either by the one who draws the sample or by those who handle it before it is used as the basis of classification. This report presents information assembled through a recent study of various methods of sampling cotton in the United States and of closely related practices insofar as they are associated with representativeness of the samples drawn. It is known that disparities can and do occur in the classification of samples from the same bales of cotton by different classers. As presumably such disparities may be due in part to differences in samples, this study was made by the Bureau of Agricultural Economics to obtain information concerning the influence of different methods of sampling cotton and of closely associated practices on the representativeness of samples drawn. Consideration was given not only to the different methods of drawing samples from cotton bales and the distinguishing characteristics of the different types of samples, but also to (a) ginning and baling practices that affect representativeness of samples, such as plating of bales at the gin, and (b) handling of samples after they are drawn, such as trimming, rolling, and packing. These factors have an important bearing upon the proper classification of cotton bales. It is possible that comparison of the different methods of sampling employed in the different parts of the country, and of handling and caring for them after they have been drawn, might lead to better and more uniform practices.

The Effects of Self-Shadowing by a Puffed up Inner Rim in Scattered Light Images of Protoplanetary Disks

description: We explore whether protoplanetary disks with self-shadowing from puffed up inner rims exhibit observable features in scattered light images. We use both self-consistent hydrostatic equilibrium calculations and parameterized models to produce the vertically puffed up inner rims. We find that, in general, the transition between the shadowed and flared regions occurs in a smooth manner over a broad radius range, and no sudden jump exists at the outer edge of the shadow in either the disk temperature or density structures. As a result, a puffed up rim cannot create sharp ring/arc/spiral-arm-like features in the outer disk as have been detected in recent direct NIR imaging of disks. On the other hand, if the puffed up rim has a sharp edge in the vertical direction, the shadowing effect can produce a distinct 3-stage broken power law in the radial intensity profile of the scattered light, with 2 steep surface brightness radial profiles in the inner and outer disk joined by a shallow transition region around the shadow edge. These types of scattered light profiles may have already been observed, such as in the recent Subaru direct imaging of the TW Hydrae system.

description: Jet substructure observables play a central role at the Large Hadron Collider for identifying the boosted hadronic decay products of electroweak scale resonances. The complete description of these observables requires understanding both the limit in which hard substructure is resolved, as well as the limit of a jet with a single hard core. In this paper we study in detail the perturbative structure of two prominent jet substructure observables, $N$-subjettiness and the energy correlation functions, as measured on background QCD jets. In particular, we focus on the distinction between the limits in which two-prong structure is resolved or unresolved. Depending on the choice of subjet axes, we demonstrate that at fixed order, $N$-subjettiness can manifest myriad behaviors in the unresolved region: smooth tails, end-point singularities, or singularities in the physical region. The energy correlation functions, by contrast, only have non-singular perturbative tails extending to the end point. We discuss the effect of hadronization on the various observables with Monte Carlo simulation and demonstrate that the modeling of these effects with non-perturbative shape functions is highly dependent on the $N$-subjettiness axes definitions. Our study illustrates those regions of phase space that must be controlled for high-precision jet substructure calculations, and emphasizes how such calculations can be facilitated by designing substructure observables with simple singular structures.

description: Despite their importance for precision QCD calculations, correlations between in- and out-of-jet regions of phase space have never directly been observed. These so-called non-global effects are present generically whenever a collider physics measurement is not explicitly dependent on radiation throughout the entire phase space. In this paper, we introduce a novel procedure based on mutual information, which allows us to isolate these non-global correlations between measurements made in different regions of phase space. We study this procedure both analytically and in Monte Carlo simulations in the context of observables measured on hadronic final states produced in $e^+e^-$ collisions, though it is more widely applicable. The procedure exploits the sensitivity of soft radiation at large angles to non-global correlations, and we calculate these correlations through next-to-leading logarithmic accuracy. The bulk of these non-global correlations are found to be described in Monte Carlo simulation. They increase by the inclusion of non-perturbative effects, which we show can be incorporated in our calculation through the use of a model shape function. This procedure illuminates the source of non-global correlations and has connections more broadly to fundamental quantities in quantum field theory.

description: The arching phenomenon is an emergent pattern formed by a $c$-sized crowd of intelligent, goal-oriented, autonomous, heterogeneous individuals moving towards a $w$-wide exit along a long $W$-wide corridor, where $W>w$. We collected empirical data from microsimulations to identify the combination effects of~$c$ and~$w$ to the time~$T$ of the onset of and the size~$S$ of the formation of the arch. The arch takes on the form of the perimeter of a half ellipse halved along the minor axis. We measured the~$S$ with respect to the lengths of the major~$M$ and minor~$m$ axes of the ellipse, respectively. The mathematical description of the formation of this phenomenon will be an important information in the design of walkways to control and easily direct the flow of large crowds, especially during panic egress conditions.

In the making: globally refiguring critique through a transformative aesthetics
Creators: name: Martin, Brigid

Subjects: Other education not elsewhere classified

description: Many areas of philosophy have yet to fully digest the impact of emerging inter-cultural and crosscultural dialogues. While fields such as political philosophy are coming to terms with how decolonial thought poses fundamental challenges to the way philosophy is practiced, aesthetics - particularly in its more theoretical and general guises - is only beginning to explore the consequences of philosophies of art and sensibility beyond the European tradition. In the spirit of what philosophers such as Brian Schroeder (2017) have called "transcontinental philosophy," and using resources from Indian, Japanese, and European philosophical traditions, this dissertation pursues a critical and dialectical approach to cross-cultural philosophical aesthetics. I have two primary goals: one methodological, and one substantive. The methodological goal is to explore how critical aesthetics is impacted at the most fundamental levels by decolonial and cross-cultural interventions. Cross-cultural philosophy poses problems and introduces innovations for the critical paradigm that are not merely extrinsic, complementary, or corrective, but have systematic consequences. The substantive goal is to explore how and to what extent aesthetic experience - particularly encounters with works of art - can be transformative in a strong sense. Using Nishida Kitarō's critical engagement with transcendentalism and Buddhist philosophy to orient my interpretation, I argue that aesthetic experience in general is a composition of expression and affect, and that artistic experience in particular involves a complex synthesis of perception and production. This means that means works of art can potentially transform our affective and expressive relations to the world, ourselves, and history, at both the individual and collective level. Consequently, art bears a unique therapeutic, ethical, and political significance. I begin with a close reading of how Immanuel Kant understands the role of the "aesthetic" within the critical project, and the significance of expression and affect in defining this role. From this point, I use conceptual interventions from Abhinavagupta to demonstrate the ways in which critical aesthetics can be broken open and structurally rethought. Following this I provide a reading of Nishida's philosophical aesthetics centred on his concepts of "active intuition" and "historically formative activity." Through the work of Maurice Merleau-Ponty I then explore how art is involved in the "institution" of perceptual perspective. Finally, through the work of Gilles Deleuze I will explore how art communicates "aesthetic Ideas" of the world and draws us into the ongoing invention of a new "sensus communis." To conclude, I offer some speculative thoughts as to the normative implications of this critical approach to transformative aesthetics.

description: [abridged] We explore the diversity of internal galaxy structures in the Coma cluster across a wide range of luminosities ($-17$\,$>$\,$M_g$\,$>$\,$-22$) and cluster-centric radii ($0$\,$ 10$ kpc). 11\% of galaxies ($N=52$) feature a break in their outer profiles, indicating `truncated' or `anti-truncated' discs. Beyond the break radius, truncated galaxies are structurally consistent with exponential discs, disfavouring physical truncation as their formation mechanism. Bulge luminosity in anti-truncated galaxies correlates strongly with galaxy luminosity, indicating a bulge-enhancing origin for these systems. Both types of broken disc are found overwhelmingly ($>70\%$) in `barred' galaxies, despite a low measured bar fraction for Coma ($20\pm2\%$). Thus, galaxy bars play an important role in formation of broken disc structures. No strong variation in galaxy structure is detected with projected cluster-centric radius.

description: We study the structure of the galaxy cluster Abell 523 (A523) at z=0.104 using new spectroscopic data for 132 galaxies acquired at the Telescopio Nazionale Galileo, new photometric data from the Isaac Newton Telescope, and X-ray and radio data from the Chandra and Very Large Array archives. We estimate the velocity dispersion of the galaxy population, sigmaV=949 km/s, and the X-ray temperature of the hot intracluster medium, kT=5.3 keV. We infer that A523 is a massive system: M200 about 7-9 x10E14 Msun. The analysis of the optical data confirms the presence of two subclusters, 0.75 Mpc apart, tracing the SSW-NNE direction and dominated by the two brightest cluster galaxies (BCG1 and BCG2). The X-ray surface brightness is strongly elongated towards the NNE direction, and its peak is clearly offset from both the BCGs. We confirm the presence of a 1.3 Mpc large radio halo, elongated in the ESE-WNW direction and perpendicular to the optical/X-ray elongation. We detect a significant radio/X-ray offset and radio polarization, two features which might be the result of a magnetic field energy spread on large spatial scales. A523 is found consistent with most scaling relations followed by clusters hosting radio haloes, but quite peculiar in the Pradio-LX relation: it is underluminous in the X-rays or overluminous in radio. A523 can be described as a binary head--on merger caught after a collision along the SSW-NNE direction. However, minor optical and radio features suggest a more complex cluster structure, with A523 forming at the crossing of two filaments along the SSW-NNE and ESE-WNW directions.

description: INTRODUCTION: Hearing loss and tinnitus are common in most populations, although few data have addressed hearing-related health among tribal members and the need for public health interventions.

METHODS: This cross-sectional study examined prevalence and risk factors for hearing loss and tinnitus among 217 adults in a Pacific Northwest tribe. Frequency measures were conducted for difficulty hearing certain sounds and hearing aid use. In 2006, risk factors were examined for two outcomes-hearing loss and tinnitus-with analysis conducted in the same year.

RESULTS: Although self-reported hearing loss was more common in men (24%) than women (13%), a larger percentage of women compared with men reported difficulty hearing certain sounds. Only 8% of study participants reported hearing aid use. After age adjustment, significant noise exposure was associated with hearing loss (OR=8.30, 95% CI=1.84, 37.52). The overall prevalence of tinnitus was 33% (similar in men and women). After adjusting for age, the odds of tinnitus in individuals with more than four ear infections was 4.77 (95% CI=1.89, 12.02) times the odds in those who never had an ear infection. Tinnitus was also associated with significant noise exposure (OR=2.24, 95% CI=1.28, 6.73) even after age adjustment.

CONCLUSIONS: Increasing age and significant noise exposure were associated with hearing loss in this tribe. Tinnitus was associated with significant noise exposure and history of otitis media, even after age adjustment. Public health efforts are needed to improve hearing-related health in this tribe through messages about noise exposure and use of hearing protection.

description: It is known that the Fresnel wave surfaces of transparent biaxial media have 4 singular points, located on two special directions. We show that, in more general media, the number of singularities can exceed 4. In fact, a highly symmetric linear material is proposed whose Fresnel surface exhibits 16 singular points. Because, for every linear material, the dispersion equation is quartic, we conclude that 16 is the maximum number of isolated singularities. The identity of Fresnel and Kummer surfaces, which holds true for media with a certain symmetry (zero skewon piece), provides an elegant interpretation of the results. We describe a metamaterial realization for our linear medium with 16 singular points. It is found that an appropriate combination of metal bars, split-ring resonators, and magnetized particles can generate the correct permittivity, permeability, and magnetoelectric moduli. Lastly, we discuss the arrangement of the singularities in terms of Kummer's (16,6)-configuration of points and planes. An investigation parallel to ours, but in linear elasticity, is suggested for future research.

description: This article examines the changing concepts of racialised citizenship in two intertwined nations: the Independent State of Papua New Guinea (‘PNG’) and the Commonwealth of Australia (‘Australia’), PNG’s former colonial ruler, as the latter sought to shake off the legacies of its recently abandoned ‘White Australia’ policy. It examines the historical intersection between PNG’s developing citizenship criteria, with its racialised articulation of who was ‘in’ and who was ‘out’, and Australia’s efforts to recast its image on the international stage as a multi-racial, non-racist and anti-imperial nation. Specifically, it demonstrates how the intersection of these policy choices impacted on a particular cohort of so-called ‘Australian Protected Persons’ (‘APPs’). APPs who happened also to fall outside PNG’s citizenship criteria were left stateless at PNG’s independence. Drawing on newly released Australian archival material, this article casts light on the particular historical moment that allowed for this outcome.

description: Group classification of a class of Benjamin-Bona-Mahony (BBM) equations with time dependent coefficients is carried out. Two equivalent lists of equations possessing Lie symmetry extensions are presented: up to point equivalence within the class of BBM equations and without the simplification by equivalence transformations. It is shown that the complete results can be achieved using either the gauging of arbitrary elements of the class by the equivalence transformations or the method of mapping between classes. As by-product of the second approach the complete group classification of a class of variable-coefficient BBM equations with forcing term is derived.

description: The Cancer Prevention and Control Research Network (CPCRN) is a thematic network dedicated to accelerating the adoption of evidence-based cancer prevention and control practices in communities by advancing dissemination and implementation science. Funded by the Centers for Disease Control and Prevention and National Cancer Institute, CPCRN has operated at two levels: Each participating Network Center conducts research projects with primarily local partners as well as multicenter collaborative research projects with state and national partners. Through multicenter collaboration, thematic networks leverage the expertise, resources, and partnerships of participating centers to conduct research projects collectively that might not be feasible individually. Although multicenter collaboration often is advocated, it is challenging to promote and assess. Using bibliometric network analysis and other graphical methods, this paper describes CPCRN’s multicenter publication progression from 2004 to 2014. Searching PubMed, Scopus, and Web of Science in 2014 identified 249 peer-reviewed CPCRN publications involving two or more centers out of 6,534 total. The research and public health impact of these multicenter collaborative projects initiated by CPCRN during that 10-year period were then examined. CPCRN established numerous workgroups around topics such as: 2-1-1, training and technical assistance, colorectal cancer control, federally qualified health centers, cancer survivorship, and human papillomavirus. The paper discusses the challenges that arise in promoting multicenter collaboration and the strategies that CPCRN uses to address those challenges. The lessons learned should broadly interest those seeking to promote multisite collaboration to address public health problems, such as cancer prevention and control.
Curveballs in protoplanetary disks - the effect of the Magnus force on planet formation
Creators: name: Forbes, John C.

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: Spinning planetesimals in a gaseous protoplanetary disk may experience a hydrodynamical force perpendicular to their relative velocities. We examine the effect this force has on the dynamics of these objects using analytical arguments based on a simple laminar disk model and numerical integrations of the equations of motion for individual grains. We focus in particular on meter-sized boulders traditionally expected to spiral in to the central star in as little as 100 years from 1 A.U. We find that there are plausible scenarios in which this force extends the lifetime of these solids in the disk by a factor of several. More importantly the velocities induced by the Magnus force can prevent the formation of planetesimals via gravitational instability in the inner disk if the size of the dust particles is larger than of order 10 cm. We find that the fastest growing linear modes of the streaming instability may still grow despite the diffusive effect of the Magnus force, but it remains to be seen how the Magnus force will alter the non-linear evolution of these instabilities.

On the discontinuity of the specific heat of the Ising model on a scale-free network

description: We consider the Ising model on an annealed scale-free network with node-degree distribution characterized by a power-law decay $P(K)\sim K^{-λ}$. It is well established that the model is characterized by classical mean-field exponents for $λ>5$. In this note we show that the specific-heat discontinuity $δc_h$ at the critical point remains $λ$-dependent even for $λ>5$: $δc_h=3(λ-5)(λ-1)/[2(λ-3)^2]$ and attains its mean-field value $δc_h=3/2$ only in the limit $λ\to \infty$. We compare this behaviour with recent measurements of the $d$ dependency of $δc_h$ made for the Ising model on lattices with $d>4$ [Lundow P.H., Markström K., Nucl. Phys. B, 2015, Vol. 895, 305].

description: We derive the joint probability distribution of the first two spectral moments for the G$β$E random matrix ensembles in N dimensions for any N. This is achieved by making use of two complementary invariants of the domain in $\mathbb{R}^N$ where the spectral moments are defined. Our approach is significantly different from those employed previously to answer related questions and potentially offers new insights. We also discuss the problems faced when attempting to include higher spectral moments.
