description: Because many of our X-ray telescopes are optimized towards observing faint sources, observations of bright sources like X-ray binaries in outburst are often affected by instrumental biases. These effects include dead time and photon pile-up, which can dramatically change the statistical inference of physical parameters from these observations. While dead time is difficult to take into account in a statistically consistent manner, simulating dead time-affected data is often straightforward. This structure makes the issue of inferring physical properties from dead time-affected observations fall into a class of problems common across many scientific disciplines. There is a growing number of methods to address them under the name of Simulation-Based Inference (SBI), aided by new developments in density estimation and statistical machine learning. In this paper, we introduce SBI as a principled way to infer variability properties from dead time-affected light curves. We use Sequential Neural Posterior Estimation to estimate the posterior probability for variability properties. We show that this method can recover variability parameters on simulated data even when dead time is variable, and present results of an application of this approach to NuSTAR observations of the galactic black hole X-ray binary GRS 1915+105.

description: We consider a particle undergoing Brownian motion in Euclidean space of any dimension, forced by a Gaussian random velocity field that is white in time and smooth in space. We show that conditional on the velocity field, the quenched density of the particle after a long time can be approximated pointwise by the product of a deterministic Gaussian density and a spacetime-stationary random field $U$. If the velocity field is additionally assumed to be incompressible, then $U\equiv 1$ almost surely and we obtain a local central limit theorem.

Improved Quantum Hypercontractivity Inequality for the Qubit Depolarizing Channel
Creators: name: Beigi, Salman
Publisher: name: arXiv
Year: 2021
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The hypercontractivity inequality for the qubit depolarizing channel $Ψ_t$ states that $\|Ψ_t^{\otimes n}(X)\|_p\leq \|X\|_q$ provided that $p\geq q> 1$ and $t\geq \ln \sqrt{\frac{p-1}{q-1}}$. In this paper we present an improvement of this inequality. We first prove an improved quantum logarithmic-Sobolev inequality and then use the well-known equivalence of logarithmic-Sobolev inequalities and hypercontractivity inequalities to obtain our main result. As applications of these results, we present an asymptotically tight quantum Faber-Krahn inequality on the hypercube, and a new quantum Schwartz-Zippel lemma.

description: We define the pion-photon Transition Distribution Amplitudes (TDA) in a field theoretic formalism from a covariant Bethe-Salpeter approach for the determination of the bound state. We apply our formalism to the Nambu - Jona Lasinio model, as a realistic theory of the pion. The obtained vector and axial TDAs satisfy all features required by general considerations. In particular, sum rules and polynomiality condition are explicitly verified. We have numerically proved that the odd coefficients in the polynomiality expansion of the vector TDA vanish in the chiral limit. The role of PCAC and the presence of a pion pole are explicitly shown.

Sensitivity of electromagnetically induced transparency to light-mediated interactions

description: Here we present a microscopic model that describes the Electromagnetically Induced Transparency (EIT) phenomenon in the multiple scattering regime. We consider an ensemble of cold three-level atoms, in a $Λ$ configuration, scattering a probe and a control field to the vacuum modes of the electromagnetic field. By first considering a scalar description of the scattering, we show that the light-mediated long-range interactions that emerge between the dipoles narrow the EIT transparency window for increasing densities and sample sizes. For a vectorial description, we demonstrate that near-field interacting terms can critically affect the atomic population transfer in the Stimulated Raman Adiabatic Passage (STIRAP). This result points out that standard STIRAP-based quantum memories in cold atomic ensembles would not reach high enough efficiencies for quantum information processing applications even in dilute regimes.

Territorial disputes : maps and mapping strategies in contemporary Canadian and Australian fiction
Creators: name: Huggan, Graham
Publisher: name: University of British Columbia
Year: 2010

description: This dissertation represents an attempt to reflect and account for the diversity of maps and mapping strategies in contemporary Canadian and Australian fiction. Its methodology, outlined in the opening chapter, draws on a combination of geographical and literary theory, placing particular emphasis on semiotic and other post-structuralist procedures (reconstructing the map as model; deconstructing the map as structure). The map is first defined as a representational model, as an historical document, and as a geopolitical claim. Its status as model, document or claim brings into play a series of mapping strategies including appropriation, division and marginalization. Attention is paid to the ways in which feminist, regional and ethnic writers have questioned these definitions and resisted or adapted these strategies. Basic principles for a "literary cartography" are thus established deriving from conceptual definitions, social and political implications, and diverse fictional applications of the map. "Grounds for comparison" are then established between English and French writing in Canada, and between the literatures of Canada and Australia, by outlining a brief history of maps and mapping strategies in those areas. Three significant precursors of the contemporary period of literary cartography are discussed: Patrick White, Margaret Atwood, and Hubert Aquin, leading to an overview of patterns and implications of cartographic imagery in contemporary Canadian and Australian fiction from 1975 to the present. The layout for this overview is fourfold: "Maps and Men" discusses the map as a constrictive or coercive device which reinforces the privileges of a patriarchal literary/cultural tradition; "Maps and Myths" examines the map as a mythic paradigm for the revision or transformation of "New World" history; "Maps and Dreams" exposes the map as an oneiric construct allied to the exercise, but also to the potential critique, of colonial authority, and "Maps and Mazes" outlines the map as a self-parodic analogue for the labyrinthine structure and diversionary tactics of the contemporary (post-colonial) literary text. Generalizations inevitably made in this overview are offset by a more detailed analysis, from a comparative perspective, of a number of specific texts. Topics for discussion in this section include the deterritorialization of "cartographic space" in contemporary fictions by women in Canada and Australia, the de/reconstruction of "New World" history in Canadian and Australian historiographic metafiction, and the promulgation of alternative hypotheses of synthesis or hybridity in the spatially and culturally decentralized ("international "/"regional ") text. The dissertation concludes by considering the wider implications of these revisionist "cartographic" procedures for post-colonial literatures and for the future of post-colonial societies/cultures seeking to free themselves from the conceptual legacy of their colonial past.

description: The Cs2CO3-promoted P-N coupling reaction of H-phosphoryl compounds and N-tosylhydrazones is reported. Formally, this transformation represents an interesting example of exchanging the sulfur and phosphorus functionalities to convert N-tosylhydrazones to N-phosphorylhydrazones. The reaction may take place via the nucleophilic interception of the in-situ generated diazo intermediates by H-phosphoryl compounds at the terminal nitrogen atom.

description: Making use of recent techniques in the theory of selfadjoint extensions of symmetric operators, we characterize the class of point interaction Hamiltonians in a 3-D bounded domain with regular boundary. In the particular case of one point interaction acting in the center of a ball, we obtain an explicit representation of the point spectrum of the operator togheter with the corresponding related eigenfunctions. These operators are used to build up a model-system where the dynamics of a quantum particle depends on the state of a quantum bit.

The effect of television advertising on consumer price sensitivity : an investigation of frequently purchased products
Creators: name: Kanetkar, Vinay
Publisher: name: University of British Columbia
Year: 2010

description: The central question studied is whether household price sensitivity increases or decreases as the number of exposures to television advertising increases. As a means of answering this question, Salop's (1979) model of brand differentiation is generalized to incorporate advertising as a managerial decision variable. Salop's generalized model is linked to a random utility choice model to estimate the effects of advertising on consumer price sensitivity. The random utility choice models are then estimated using household level scanner panel data for two product categories (dry dog food and aluminum foil). The generalization of Salop's model shows that the direct effect of a firm's increased advertising is a lowering of price sensitivity. In addition, the model also shows that increased advertising may result in a higher or lower price sensitivity depending upon the advertising reaction of competitors. The empirical results for both product categories studied indicate that increased advertising is associated with higher price sensitivity. However, since the aluminum foil product category has only one major national advertiser, the results here cannot be fully explained by Salop's generalized model and thus show an important limitation of the model's applicability. Brand loyalty has proved to be the most important explanatory variable in random utility brand choice models for low cost brand identified consumer products (Guadagni and Little 1983). This dissertation develops a new measure of brand loyalty that is sensitive to the temporal pattern of household's previous brand purchases. For the product categories, studied, this new measure is superior to those proposed earlier. In addition, this work confirms the robust nature of Guadagni and Little's (1983) model of brand choice and shows that both television advertising and sales promotional variables have a significant impact on brand choice.

Rectification and nonlinear transport in chaotic dots and rings

description: We investigate the nonlinear current-voltage characteristic of mesoscopic conductors and the current generated through rectification of an alternating external bias. To leading order in applied voltages both the nonlinear and the rectified current are quadratic. This current response can be described in terms of second order conductance coefficients and for a generic mesoscopic conductor they fluctuate randomly from sample to sample. Due to Coulomb interactions the symmetry of transport under magnetic field inversion is broken in a two-terminal setup. Therefore, we consider both the symmetric and antisymmetric nonlinear conductances separately. We treat interactions self-consistently taking into account nearby gates. The nonlinear current is determined by different combinations of second order conductances depending on the way external voltages are varied away from an equilibrium reference point (bias mode). We discuss the role of the bias mode and circuit asymmetry in recent experiments. In a photovoltaic experiment the alternating perturbations are rectified, and the fluctuations of the nonlinear conductance are shown to decrease with frequency. Their asymptotical behavior strongly depends on the bias mode and in general the antisymmetric conductance is suppressed stronger then the symmetric conductance. We next investigate nonlinear transport and rectification in chaotic rings. To this extent we develop a model which combines a chaotic quantum dot and a ballistic arm to enclose an Aharonov-Bohm flux. In the linear two-probe conductance the phase of the Aharonov-Bohm oscillation is pinned while in nonlinear transport phase rigidity is lost. We discuss the shape of the mesoscopic distribution of the phase and determine the phase fluctuations.

description: A singular foliation on a complete riemannian manifold M is said to be riemannian if each geodesic that is perpendicular at one point to a leaf remains perpendicular to every leaf it meets. We prove that the regular leaves are equifocal, i.e., the end point map of a normal foliated vector field has constant rank. This implies that we can reconstruct the singular foliation by taking all parallel submanifolds of a regular leaf with trivial holonomy. In addition, the end point map of a normal foliated vector field on a leaf with trivial holonomy is a covering map. These results generalize previous results of the authors on singular riemannian foliations with sections.

description: Transverse-momentum-dependent parton distribution functions and wave functions (TMDPDFs/TMDWFs) can be extracted from lattice calculations of appropriate Euclidean matrix elements of staple-shaped Wilson line operators. We investigate the mixing pattern of such operators under lattice renormalization using symmetry considerations. We perform an analysis for operators with all Dirac structures, which reveals mixings that are not present in one-loop lattice perturbation theory calculations. We also present the relevant one-loop matching in a renormalization scheme that does not introduce extra non-perturbative effects at large distances, both for the TMDPDFs and for the TMDWFs. Our results have the potential to greatly facilitate numerical calculations of TMDPDFs and TMDWFs on the lattice.

The measurements are part of an ongoing programme to measure the spectral energy distributions of flat spectrum radio sources and to correlate them with the milliarcsecond structures from VLBI and other measured astrophysical properties. The 30-GHz data were obtained with a twin-beam differencing radiometer system mounted on the Torun 32-m telescope. The system has an angular resolution of 1.2 arcmin. Together with radio spectral data obtained from the literature, the 30-GHz data have enabled us to identify 42 of the CJF sources as Giga-hertz Peaked Spectrum (GPS) sources. Seventeen percent of the sources have rising spectra (alpha > 0) between 5 and 30 GHz.

description: We introduce dPV, an end-to-end differentiable photovoltaic (PV) cell simulator based on the drift-diffusion model and Beer-Lambert law for optical absorption. dPV is programmed in Python using JAX, an automatic differentiation (AD) library for scientific computing. Using AD coupled with the implicit function theorem, dPV computes the power conversion efficiency (PCE) of an input PV design as well as the derivative of the PCE with respect to any input parameters, all within comparable time of solving the forward problem. We show an example of perovskite solar-cell optimization and multi-parameter discovery, and compare results with random search and finite differences. The simulator can be integrated with optimization algorithms and neural networks, opening up possibilities for data-efficient optimization and parameter discovery.

Prenant appui sur l’exemple de la mathématique et de l’anthropologie, il s’agit tout particulièrement de mettre en exergue le dialogue interculturel, les relations interdisciplinaires qui ont uni le mathématicien bourbakiste André Weil et l’ethno-anthropologue Claude Lévi-Strauss lors de leur exil américain dans les années 1940. Dans un premier temps, nous essaierons de montrer les conditions de production dans lesquelles a été inaugurée cette relation, puis, nous analyserons la fécondité de cette interculturalité quasi-inédite en son temps qui a conduit les deux universitaires à établir concrètement des ponts durables entre leurs disciplines aux niveaux conceptuel et méthodologique. Notre objectif est de montrer comment se crée le croisement, la circulation et l’interpénétration entre des disciplines dont le rapprochement peut sembler au départ insoupçonné comme c’est le cas entre les sciences exactes et les sciences humaines et sociales.

Faraday law, oxidation numbers, and ionic conductivity: The role of topology
Creators: name: Resta, Raffaele
Publisher: name: arXiv
Year: 2021
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: Faraday's experiment measures -- within a modern view -- the charge adiabatically transported over a macroscopic distance by a given nuclear species in insulating liquids: the reason why it is integer is deeply rooted in topology. Whole numbers enter chemistry in a different form: atomic oxidation states. They are not directly measurable, and are determined instead from an agreed set of rules. Insulating liquids are a remarkable exception: Faraday's experiment indeed measures the oxidation numbers of each dissociated component in the liquid phase, whose topological values are unambiguous. Ionic conductivity in insulating liquids is expressed in terms of the autocorrelation function of the fluctuating charge current at a given temperature in zero electric field; topology plays a major role in this important observable as well. The existing literature deals with the above issues by adopting the independent-electron framework; here I provide the many-body generalization of all the above findings, which furthermore allows for compact and very transparent notations and formulas.

Mathematical models and solution algorithms for the vehicle routing
      problem with environmental considerations
Creators: name: Raeesi, Ramin
Publisher: name: Lancaster University
Year: 2019

description: Urban freight distribution is essential for the functioning of urban
      economies. However, it is contributing significantly to problems such as
      traffic congestion and environmental pollution. The main goal of this
      research is to contribute to greening urban freight distribution by
      developing new mathematical models and solution algorithms pertaining to
      the two major steams in Vehicle Routing Problems (VRPs) with environmental
      considerations: (i) VRPs with an explicit fuel consumption estimation
      component as a proxy for emissions, and (ii) VRPs with vehicles in the
      fleet that run on a cleaner alternative fuel such as electricity.

      In the first stream, this thesis develops and solves a new realistic
      multi-objective variant of the pollution-routing problem, referred to as
      the Steiner Pollution-Routing Problem (SPRP), that is studied directly on
      the original urban roadway network. The proposed variant is capable of
      incorporating the real operating conditions of urban freight distribution,
      and striking a balance between traditional business and environmental
      objectives, while integrating all factors that have a major impact on fuel
      consumption, including the time-varying congestion speed, vehicle load,
      vehicle’s physical and mechanical characteristics, and acceleration and
      deceleration rates. The thesis develops new combinatorial results that
      facilitate problem solution on the original roadway network and also
      introduces new mathematical models for synthesizing the expected
      second-by-second driving cycle of a vehicle over a given road-link at a
      given time of the day. New efficient multi-objective optimisation
      heuristics are also developed for addressing realistic instances of the
      SPRP.

      On the other hand, in the latter stream discussed above, to tackle the
      significantly impeding problem of range anxiety in the face of goods
      distribution using Electric Commercial Vehicles (ECVs), a paradigm shift
      in the routing of ECVs is proposed by introducing the Electric Vehicle
      Routing Problem with Synchronised Ambulant Battery Swapping/Recharging
      (EVRP-SABS). The proposed problem exploits new technological developments
      corresponding to the possibility of mobile battery swapping (or
      recharging) of ECVs using a Battery Swapping Van (BSV). In the EVRP-SABS,
      routing takes place in two levels for the ECVs that carry out delivery
      tasks, and for the BSVs that provide the running ECVs with fully charged
      batteries on their route. There is, therefore, a need to establish
      temporal and spatial synchronisations between the vehicles in the two
      levels and to do so new combinatorial results and a new solution algorithm
      is proposed.

description: We present a detailed study of the electronic and magnetic interactions of Ba2CoO4, structurally very uncommon because of the isolated CoO4 distorted tetrahedral coordination. We show the presence of Co(d)-O(p) hybridized states characterized by spin polarized oxygen atoms, with their magnetic moments parallel to that on Co. The calculated isotropic exchange interaction parameters, which include the contributions from ligand spins, demonstrate the presence of a 3D network of magnetic couplings, that are partially frustrated in the identified magnetic ground state. Our results indicate that the dominant indirect exchange mechanism responsible for this ground state is mediated by O atoms along the Co-O...O-Co path.

Contested knowing : narratological readings of Daphne Marlatt's How hug a stone and Nicole Brossard's Picture theory
Creators: name: Knutson, Susan Lynne
Publisher: name: University of British Columbia
Year: 2010

description: This study begins with a question: what are the formal attributes of narrative in the feminine? Structural analysis of narrative posits a universal narrative grammar based on the quest: a subject seeks an object. At its most abstract, a subject crosses a boundary. Within this teleological framework, the subject's progress is complicated by helpers and opponents. Teresa de Lauretis argues that this narrative grammar implicates binary, patriarchal gender. How is such a grammar transformed by feminist writing? Narratological analysis of Daphne Marlatt's How Hug a Stone and Nicole Brossard's Picture Theory permits systematic description at the three interpretive levels of fabula, story and text, and thus enables comparison with hypothetical universal narrative grammar. Narratological analysis illuminates the ways that both Marlatt and Brossard transform the quest into more open-ended, gender-neutral and female-positive forms. In How Hug a Stoner the narrator's quest for her mother becomes a journey into the mothertongue and the realm of the arche-mother. The quest structure is displaced from the structuring level of fabula to the level of story, where it is a function of the powerful focalization by a paradigmatic female subject-in-formation. In Picture Theory, Nicole Brossard develops a dialogic narrative grammar involving a multiple lesbian actant who separates, reassembles and generates energy. This energy guides the actant in a spiralling movement out of the circle of "f6minit6," towards the Utopia signified by a hologram of "la femme integrale." Both authors generate a fabula structure which thwarts the generically masculine and single questing hero. At the story level, Marlatt pushes focalization to the limits of language, and in so doing, provides formal criteria for "writing the body." Brossard refuses single focus, engaging multiple perspectives which "metamorphose mental space" and "open the mind." At the textual level, both authors construct meaning intertextually, thus acknowledging the collectivity of meaning. Both face the consequences of writing as a woman, and in so doing, contribute to a new epistemology which validates the experience of women.

description: We describe the outcome of a data challenge conducted as part of the Dark Machines Initiative and the Les Houches 2019 workshop on Physics at TeV colliders. The challenged aims at detecting signals of new physics at the LHC using unsupervised machine learning algorithms. First, we propose how an anomaly score could be implemented to define model-independent signal regions in LHC searches. We define and describe a large benchmark dataset, consisting of >1 Billion simulated LHC events corresponding to $10~\rm{fb}^{-1}$ of proton-proton collisions at a center-of-mass energy of 13 TeV. We then review a wide range of anomaly detection and density estimation algorithms, developed in the context of the data challenge, and we measure their performance in a set of realistic analysis environments. We draw a number of useful conclusions that will aid the development of unsupervised new physics searches during the third run of the LHC, and provide our benchmark dataset for future studies at https://www.phenoMLdata.org. Code to reproduce the analysis is provided at https://github.com/bostdiek/DarkMachines-UnsupervisedChallenge.

An analysis of celestial pole offset observations in the free core nutation frequency band

description: In this study, three empirical Free Core Nutation (FCN) models developed to the present time, MHB2000, Malkin's and Lambert's ones, are compared on the basis of representation of variations of the FCN amplitude and phase predicted by these models. It is possible to conclude, that the model of the author provides the most realistic representation of the FCN variations. However, the specified models are based on representation about single FCN rotational mode. At the same time, some results of processing of the VLBI observations made during last years, specify possible presence of two close FCN periods. A theoretical explanation to presence of a second FCN frequency FCN has been given by G. Krasinsky in his theory of rotation of the Earth with two-layer liquid core, ERA2005. In the present work, for more detailed studying this phenomenon, the IVS time series of celestial pole offset, and also those predicted by the ERA2005 theory, have been investigated by means of several statistical methods which confidently show presence of two fluctuations in nutational movement of an Earth's rotation axis with the periods about -452 and -410 solar days.

description: Convolutional dictionary learning (CDL), the problem of estimating shift-invariant templates from data, is typically conducted in the absence of a prior/structure on the templates. In data-scarce or low signal-to-noise ratio (SNR) regimes, learned templates overfit the data and lack smoothness, which can affect the predictive performance of downstream tasks. To address this limitation, we propose GPCDL, a convolutional dictionary learning framework that enforces priors on templates using Gaussian Processes (GPs). With the focus on smoothness, we show theoretically that imposing a GP prior is equivalent to Wiener filtering the learned templates, thereby suppressing high-frequency components and promoting smoothness. We show that the algorithm is a simple extension of the classical iteratively reweighted least squares algorithm, independent of the choice of GP kernels. This property allows one to experiment flexibly with different smoothness assumptions. Through simulation, we show that GPCDL learns smooth dictionaries with better accuracy than the unregularized alternative across a range of SNRs. Through an application to neural spiking data, we show that GPCDL learns a more accurate and visually-interpretable smooth dictionary, leading to superior predictive performance compared to non-regularized CDL, as well as parametric alternatives.

description: Fewer but larger stores than a decade ago characterize the U.S. supermarket industry. The conventional store size of 10,000 to 30,000 square feet (ft2 ) is being succeeded by superstores of 30,000 to 50,000 ft2. Format, size, sales volume, location, operating hours, and services are changing to meet the needs of the consumer. According to a 1982 survey, coupon redemption was the most popular service offered by supermarkets. Utility bill payments were the least popular. Twenty-nine percent of the stores surveyed were open longer than 15 hours per day, with 42 percent of these open 24 hours.

description: Tradução de leaflet do Projeto AGFORWARD - Em sistemas silvopastoris, a interceção da luz afeta a produtividade da flora debaixo das copas de várias formas. Em geral, a produção herbácea diminui com a redução da intensidade da luz. Assim, o uso de cultivares tolerantes à sombra de espécies selecionadas pode ter um papel importante numa gestão silvopastoril bem-sucedida. Devido à sua capacidade de fixação do azoto, a incorporação de espécies de leguminosas tolerantes à sombra pode desempenhar um papel especial no aumento da qualidade e da produtividade dos sistemas silvopastoris e na melhoria da fertilidade do solo.
Competition, Trait Variance Dynamics, and the Evolution of a Species' Range

description: Geographic ranges of communities of species evolve in response to environmental, ecological, and evolutionary forces. Understanding the effects of these forces on species' range dynamics is a major goal of spatial ecology. Previous mathematical models have jointly captured the dynamic changes in species' population distributions and the selective evolution of fitness-related phenotypic traits in the presence of an environmental gradient. These models inevitably include some unrealistic assumptions, and biologically reasonable ranges of values for their parameters are not easy to specify. As a result, simulations of the seminal models of this type can lead to markedly different conclusions about the behavior of such populations, including the possibility of maladaptation setting stable range boundaries. Here, we harmonize such results by developing and simulating a continuum model of range evolution in a community of species that interact competitively while diffusing over an environmental gradient. Our model extends existing models by incorporating both competition and freely changing intraspecific trait variance. Simulations of this model predict a spatial profile of species' trait variance that is consistent with experimental measurements available in the literature. Moreover, they reaffirm interspecific competition as an effective factor in limiting species' ranges, even when trait variance is not artificially constrained. These theoretical results can inform the design of, as yet rare, empirical studies to clarify the evolutionary causes of range stabilization.
Collisional Velocities and Rates in Resonant Planetesimal Belts

description: We consider a belt of small bodies around a star, captured in one of the external or 1:1 mean-motion resonances with a massive perturber. The objects in the belt collide with each other. Combining methods of celestial mechanics and statistical physics, we calculate mean collisional velocities and collisional rates, averaged over the belt. The results are compared to collisional velocities and rates in a similar, but non-resonant belt, as predicted by the particle-in-a-box method. It is found that the effect of the resonant lock on the velocities is rather small, while on the rates more substantial. The collisional rates between objects in an external resonance are by about a factor of two higher than those in a similar belt of objects not locked in a resonance. For Trojans under the same conditions, the collisional rates may be enhanced by up to an order of magnitude. Our results imply, in particular, shorter collisional lifetimes of resonant Kuiper belt objects in the solar system and higher efficiency of dust production by resonant planetesimals in debris disks around other stars.
