description: Flocks of birds, schools of fish, insects swarms are examples of coordinated motion of a group that arises spontaneously from the action of many individuals. Here, we study flocking behavior from the viewpoint of multi-agent reinforcement learning. In this setting, a learning agent tries to keep contact with the group using as sensory input the velocity of its neighbors. This goal is pursued by each learning individual by exerting a limited control on its own direction of motion. By means of standard reinforcement learning algorithms we show that: i) a learning agent exposed to a group of teachers, i.e. hard-wired flocking agents, learns to follow them, and ii) that in the absence of teachers, a group of independently learning agents evolves towards a state where each agent knows how to flock. In both scenarios, i) and ii), the emergent policy (or navigation strategy) corresponds to the polar velocity alignment mechanism of the well-known Vicsek model. These results show that a) such a velocity alignment may have naturally evolved as an adaptive behavior that aims at minimizing the rate of neighbor loss, and b) prove that this alignment does not only favor (local) polar order, but it corresponds to best policy/strategy to keep group cohesion when the sensory input is limited to the velocity of neighboring agents. In short, to stay together, steer together.

Family activiy baggies : linking play and literacy at home
Creators: name: Hartley, L. D.
Publisher: name: The University of British Columbia
Year: 2014

description: Framed by socio-cultural theory and third space theory, this paper examines the role of play in the literacy lives of Kindergarten-aged children. First, the definitions of both play and literacy are examined. Next, a review of literature examines the role of play on young children's development of literacy at home and at school. Knowing that student success is impacted by the home environment, the literature review also examines the role of parents on the literacy development of their children. Finally, the paper suggests implementing a play-based literacy program at school as a means of supporting parents as they enhance their child's literacy development at home.

description: It is shown that the presence of multiple time scales at a quantum critical point can lead to a breakdown of the loop expansion for critical exponents, since coefficients in the expansion diverge. Consequently, results obtained from finite-order perturbative renormalization-group treatments may be not be an approximation in any sense to the true asymptotic critical behavior. This problem manifests itself as a non-renormalizable field theory, or, equivalently, as the presence of a dangerous irrelevant variable. The quantum ferromagnetic transition in disordered metals provides an example.

description: We evaluate theoretically the interaction of the open bottom and strange systems $\bar B\bar K$, $\bar B^* \bar K$, $\bar B\bar K^*$ and $\bar B^*\bar K^*$ to look for possible bound states which could correspond to exotic non--quark-antiquark mesons since they would contain at least one $b$ and one $s$ quarks. The s-wave scattering matrix is evaluated implementing unitarity by means of the Bethe-Salpeter equation, with the potential kernels obtained from contact and vector meson exchange mechanisms. The vertices needed are supplied from Lagrangians derived from suitable extensions of the hidden gauge symmetry approach to the bottom sector. We find poles below the respective thresholds for isospin 0 interaction and evaluate the widths of the different obtained states by including the main sources of imaginary part, which are the $B^*\to Bγ$ decay in the $\bar B^* \bar K$ channels, the $K^*\to K π$ in the channels involving a $K^*$, plus the box diagrams with $\bar B\bar K$ and $\bar B^*\bar K$ intermediate states for the $\bar B^*\bar K^*$ channels.

description: We construct a one-parameter family of generalized Mathieu functions, which are reduced quaternion-valued functions of a pair of real variables lying in an ellipse, and which we call $λ$-reduced quaternionic Mathieu functions. We prove that the $λ$-RQM functions, which are in the kernel of the Moisil-Teodorescu operator $D+λ$ ($D$ is the Dirac operator and $λ\in\mathbb{R}\setminus\{0\}$), form a complete orthogonal system in the Hilbert space of square-integrable $λ$-metamonogenic functions with respect to the $L^2$-norm over confocal ellipses. Further, we introduce the zero-boundary $λ$-RQM-functions, which are $λ$-RQM functions whose scalar part vanishes on the boundary of the ellipse. The limiting values of the $λ$-RQM functions as the eccentricity of the ellipse tends to zero are expressed in terms of Bessel functions of the first kind and form a complete orthogonal system for $λ$-metamonogenic functions with respect to the $L^2$-norm on the unit disk. A connection between the $λ$-RQM functions and the time-dependent solutions of the imaginary-time wave equation in the elliptical coordinate system is shown.

description: We propose that the Higgs phase of a gauge Higgs theory is the phase of spontaneously broken custodial symmetry, and present a new gauge invariant order parameter for custodial symmetry breaking which is very closely analogous to the Edwards-Anderson order parameter for spin glasses. Custodial symmetry is a global symmetry acting on the Higgs field alone, and we show here that the spin glass transition in gauge Higgs theories, from a QCD-like phase to a Higgs phase of broken custodial symmetry, coincides with the transition between two distinct types of confinement. These are color confinement in the Higgs phase, and a stronger version of confinement, which we have termed "separation-of-charge" confinement, in the QCD-like phase.

description: This issue brief reviews the drivers (long term and short term), their impacts, and indicators of food and nutrition security (FNS). The FAO defined food and nutrition security as a situation “when all people, at all times, have physical and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life” (FAO 2006). This definition of FNS highlights four dimensions of food security: food availability, access to food, the utilization of food, and the stability of these three dimensions. FNS is clearly an individual-specific outcome, but many of its indicators and of its drivers (causes) are measured at macro level and can only serve as proxies for FNS (individual) outcomes. Availability, accessibility and stability reflect the issue of the adequacy of dietary intake and a number of existing indicators can be used to approximate it, like per capita net calories available in a given country, share of food in total household expenditures, or per capita food supply variability. Individual level indicators like stunting and over- and underweight can cover the utilization dimension of FNS.

description: We examine the influence of the edge electronic density profile and of dissipation on edge magnetoplasmons in the quantum Hall regime, in a semiclassical calculation. The equilibrium electron density on the edge, obtained using a Thomas-Fermi approach, has incompressible stripes produced by energy gaps responsible for the quantum Hall effect. We find that these stripes have an unobservably small effect on the edge magnetoplasmons. But dissipation, included phenomenologically in the local conductivity, proves to produce significant oscillations in the strength and speed of edge magnetoplasmons in the quantum Hall regime.

description: The authors examine the impact of retail promotions, specifically, store coupons, manufacturer coupons, and store features on the decision to purchase private label products. To identify these effects, a probit model is specified and estimated, which allows the calculation of the probability that the private label product is chosen conditional on a set of explanatory variables. Attention is centered on American processed cheese transactions. The source of the data is ACNielsen Homescan Panel of U.S. households for calendar years 2005 and 2006. Retail promotion using store coupons had a significant negative effect on the decision to purchase private label products. In our sample, store coupons were used to purchase both private label products and national brands. A strong negative relationship was found between national brand manufacturer couponing activity and the decision to purchase private label products. Therefore, national brand couponing appears to be an effective strategy for manufacturers to deter private label growth, at least in the processed cheese market. This analysis also shows that the decision of purchasing a private label cheese product is influenced by several sociodemographic characteristics of the household, namely household income and size, age and education of the household head, race, ethnicity, and location.

description: In this work, we carry out a suite of specially-designed numerical simulations to shed further light on dark matter (DM) subhalo survival at mass scales relevant for gamma-ray DM searches, a topic subject to intense debate nowadays. Specifically, we have developed and employed an improved version of DASH, a GPU $N$-body code, to study the evolution of low-mass subhaloes inside a Milky Way-like halo with unprecedented accuracy, reaching solar-mass and sub-parsec resolution in our simulations. We simulate subhaloes with varying mass, concentration, and orbital properties, and consider the effect of the gravitational potential of the Milky Way galaxy itself. More specifically, we analyze the evolution of both the bound mass fraction and annihilation luminosity of subhaloes, finding that most subhaloes survive until present time, even though in some cases they lose more than 99% of their mass at accretion. Baryons in the host induce a much more severe mass loss, especially when the subhalo orbit is more parallel to the galactic disk. Many of these subhaloes cross the solar galactocentric radius, thus making it easier to detect their annihilation fluxes from Earth. We find subhaloes orbiting a DM-only halo with a pericentre in the solar vicinity to lose 70-90% of their initial annihilation luminosity at redshift zero, which increases up to 99% when baryons are also included in the host. We find a strong relation between subhalo's mass loss and the effective tidal field at pericentre. Indeed, much of the dependence on concentration, orbital parameters, host potential and baryonic components can be explained through this single parameter. In addition to shedding light on the survival of low-mass galactic subhaloes, our results can provide detailed predictions that will aid current and future quests for the nature of DM.

Vortex axis tracking by iterative propagation (VATIP): a method for analysing three-dimensional turbulent structures
Creators: name: Zhu, Lu
name: Xi, Li

Year: 2019
Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: Vortex is a central concept in the understanding of turbulent dynamics. Objective algorithms for the detection and extraction of vortex structures can facilitate the physical understanding of turbulence regeneration dynamics by enabling automated and quantitative analyses of these structures. Despite the wide availability of vortex identification criteria, they only label spatial regions belonging to vortices, without any information on the identity, topology and shape of individual vortices. This latter information is stored in the axis lines lining the contours of vortex tubes. In this study, a new tracking algorithm is proposed which propagates along the vortex axis lines and iteratively searches for new directions for growth. The method is validated in flow fields from transient simulations where vortices of different shapes are controllably generated. It is then applied to statistical turbulence for the analysis of vortex configurations and distributions. It is shown to reliably extract axis lines for complex three-dimensional vortices generated from the walls. A new procedure is also proposed that classifies vortices into commonly observed shapes, including quasi-streamwise vortices, hairpins, hooks and branches, based on their axis-line topology. Clustering analysis is performed on the extracted axis lines to reveal vortex organization patterns and their potential connection to large-scale motions in turbulence.

Exploring the role of corrective feedback in second language writing
Creators: name: Herrera, Sylvana Lucia
Publisher: name: The University of British Columbia
Year: 2014

description: The purpose of this paper is to explore what research says about the role of corrective feedback in second language writing. Error correction in writing has been a contentious issue as researchers debated the effectiveness in helping improve learner's linguistic accuracy in writing. This debate was the impetus for further research that attempted to address whether written CF facilitates L2 acquisition. This paper reviews the background of this debate and looks at some of the major research on this issue and its conclusions. In so doing, it looks at the different written corrective feedback (WCF) types, direct, indirect, metalinguistic and focused feedback and their role in helping students improve their accuracy of problematic linguistic features. Recent research is presented which suggests that focused WCF leads to gains in linguistic accuracy (Sheen, 2007). In the connections to practice section I propose to do a teacher information workshop to present these research findings and suggest some ways to implement WCF in the second language classroom. In this workshop teachers will be informed of the strengths and limitations of using each type of WCF to help make them aware of the range of feedback available in order to provide targeted feedback effectively. The paper concludes with future implications for the classroom.

description: Imports of food products are often seen primarily as a threat to domestic producers while the broader economic impacts are ignored. Research on rapidly growing U.S. avocado imports has focused on the consequences for the U.S. avocado industry. This study conducts an economic impact analysis to measure the level and industry distribution of any benefits of U.S. imports of avocados from Mexico that may accrue to the U.S. national economy. We find that the US$1.5 billion in U.S. imports of Mexican avocados in 2015 had a positive and statistically significant effect on the U.S. economy in that year. Every dollar of avocado imports from Mexico in 2015 generated US$2.31 in U.S. output, US$1.41 in U.S. GDP, and US$0.79 in U.S. labor income. About 12.3 jobs were generated per US$1 million of imports. A separate econometric analysis corroborates the result. We conclude that imports of Mexican avocados are pro-growth for the U.S. economy.

description: Phonons in nearly optimally doped HgBa$_2$CuO$_{4+δ}$ were studied by inelastic X-ray scattering. The dispersion of the low energy modes is well described by a shell model, while the Cu-O bond stretching mode at high energy shows strong softening towards the zone boundary, which deviates strongly from the model. This seems to be common in the hole-doped high-$T_\mathrm{c}$ superconducting cuprates, and, based on this work, not related to a lattice distortion specific to each material.

description: The high-velocity, neutral hydrogen feature known as MI may be the result of a supernova that took place about 100,000 years ago at a distance of 163 pc. Low-velocity HI data show a clear cavity, a structure indicative of regions evacuated by old exploding stars, centered on the spatial coordinates of MI, (l,b) = (165o, 65.o5). The invisible companion of the yellow giant star, 56 Ursae Majoris, may be the remains of the supernova that evacuated the cavity and blasted MI itself outward at 120 km/s. The mass and energy of MI are easily in line with what is expected from a supernova. The X-rays seen by ROSAT are consistent with an origin in the resulting bow shock. Ironically, this scenario for MI only came together because we were exploring low-velocity gas in the direction of high-velocity clouds.

description: Reversible data hiding in encrypted images (RDHEI) receives growing attention because it protects the content of the original image while the embedded data can be accurately extracted and the original image can be reconstructed lossless. To make full use of the correlation of the adjacent pixels, this paper proposes an RDHEI scheme based on pixel prediction and bit-plane compression. Firstly, to vacate room for data embedding, the prediction error of the original image is calculated and used for bit-plane rearrangement and compression. Then, the image after vacating room is encrypted by a stream cipher. Finally, the additional data is embedded in the vacated room by multi-LSB substitution. Experimental results show that the embedding capacity of the proposed method outperforms the state-of-the-art methods.
A new approach to the Fourier extension problem for the paraboloid

Year: 2021
Subjects: subject: Classical Analysis and ODEs (math.CA)

description: We propose a new approach to the Fourier restriction conjectures. It is based on a discretization of the Fourier extension operators in terms of quadratically modulated wave packets. Using this new point of view, and by combining natural scalar and mixed norm quantities from appropriate level sets, we prove that all the $L^{2}$-based $k$-linear extension conjectures are true up to the endpoint for every $1 \leq k \leq d+1$ if one of the functions involved is a full tensor. We also introduce the concept of \textit{weak transversality}, under which we show that all conjectured $L^{2}$-based multilinear extension estimates are still true up to the endpoint provided that one of the functions involved has a weaker tensor structure, and we prove that this result is sharp. Under additional tensor hypotheses, we show that one can improve the conjectured threshold of these problems in some cases. In general, the largely unknown multilinear extension theory beyond $L^{2}$ inputs remains open even in the bilinear case; with this new point of view, and still under the previous tensor hypothesis, we obtain the near-restriction target for the $k$-linear extension operator if the inputs are in a certain $L^{p}$ space for $p$ sufficiently large. The proof of this result is adapted to show that the $k$-fold product of linear extension operators (no transversality assumed) also ``maps near restriction" if one input is a tensor. Finally, we exploit the connection between the geometric features behind the results of this paper and the theory of Brascamp-Lieb inequalities, which allows us to verify a special case of a conjecture by Bennett, Bez, Flock and Lee.

description: The microscopic and the macroscopic properties of A-superstatistics, related to the class A(0,n-1)\equiv sl(1|n) of simple Lie superalgebras are investigated. The algebra sl(1|n) is described in terms of generators f_1^\pm, >..., f_n^\pm, which satisfy certain triple relations and are called Jacobson generators. The Fock spaces of A-superstatistics are investigated and the Pauli principle of the corresponding statistics is formulated. Some thermal properties of A-superstatistics are constructed under the assumption that the particles interact only via statistical interaction imposed by the Pauli principle. The grand partition function and the average number of particles are written down explicitly in the general case and in two particular examples: 1) the particles have one and the same energy and chemical potential; 2) the energy spectrum of the orbitals is equidistant.

description: We study the closed string emission from an unstable D$p$-brane with constant background electric field in bosonic string theory. The average total number density and the average total energy density of emitted closed strings are explicitly calculated in the presence of electric field. It is explicitly shown that the energy density in the UV region becomes finite whenever the background electric field is switched on. The energy density converted into closed strings in the presence of electric field is negligibly small compared with the D-brane tension in the weak string coupling limit.

description: We performed Monte Carlo calculations of the statistical distribution of the $χ^2$ test statistic used in the analysis of the data of the NEOS, DANSS, Bugey-3, and PROSPECT short-baseline reactor experiments. We show that the statistical significance of the NEOS and DANSS indications in favor of active-sterile neutrino oscillations is smaller than that obtained with the usual method based on the $χ^2$ distribution. In the combined analysis of the data of the four experiments we find that the statistical significance of active-sterile neutrino oscillations is reduced from $2.4σ$ to $1.8σ$.

description: Considering cold, dense quark matter with two massless quark flavors, we demonstrate how, in a self-consistent calculation in the framework of QCD, the condensation of Cooper pairs induces a non-vanishing background color field. This background color field has precisely the right magnitude to cancel tadpole contributions and thus ensures overall color neutrality of the two-flavor color superconductor.

description: Elias 2-27 is a young star that hosts an extended, bright and inclined disk of dust and gas. The inclination and extreme flaring of the disk make Elias 2-27 an ideal target to study the vertical distribution of molecules, particularly CN. We directly trace the emission of CN in Elias 2-27 and compare it to previously published CO isotopologue data. CN $N = 3-2$ emission is analyzed in two different transitions $J = 7/2 - 5/2$ and $J = 5/2 - 3/2$, for which we detect two hyperfine group transitions. The vertical location of CN emission is traced directly from the channel maps, following geometrical methods that have been previously used to analyze the CO emission of Elias 2-27. Analytical models are used to parametrize the vertical profile of each molecule and study the extent of each tracer, additionally we compute radial profiles of column density and optical depth. We show that the vertical location of CN and CO isotopologues in Elias 2-27 is layered and consistent with predictions from thermochemical models. A north/south asymmetry in the radial extent of CN is detected and we find that the CN emission is mostly optically thin and constrained vertically to a thin slab at $z/r \sim$0.5. A column density of 10$^{14}$\,cm$^{-2}$ is measured in the inner disk which for the north side decreases to 10$^{12}$\,cm$^{-2}$ and for the south side to 10$^{13}$\,cm$^{-2}$ in the outer regions. In Elias 2-27, CN traces a vertically elevated region above the midplane, very similar to that traced by $^{12}$CO. The inferred CN properties are consistent with thermo-chemical disk models, in which CN formation is initiated by the reaction of N with UV-pumped H$_2$. The observed north/south asymmetry may be caused by either ongoing infall or by a warped inner disk. This study highlights the importance of tracing the vertical location of various molecules to constrain the disk physical conditions.

description: This paper analyzes the price impact of long-only index funds in commodity futures markets for the January 2004 through July 2008 period. Daily positions of index traders in 12 markets are drawn from the internal large trader reporting system used by the CFTC. Granger causality test results provide negligible evidence that index traders impact commodity future returns regardless of the measure of market participation considered. The signs of the relatively few significant coefficients are as likely to be negative as positive and the magnitudes of the economic effects are very small. Some evidence is found that volatility has been influenced by the presence of index traders in several markets, but only using one of the measures of index position changes. These effects appear to be small in economic magnitude, except in several traditionally less liquid markets. While the overall balance between significant positive and negative signs is nearly equal, index positions appear to have had a dampening effect on volatility during 2004-2005 particularly in the soft commodity contracts, followed by a heightening effect during 2006-2008 in deferred contracts.

description: Coupling isotope values of feathers and satellite tracking of individuals have the potential to reveal multi-season linkages between wintering habitat, diet and carry-over effects on reproductive parameters in migrating birds. Snowy owls Bubo scandiacus have multiple wintering tactics as they can use both terrestrial and marine resources during the non-breeding season, but their nomadic behaviour complicates their study. We assessed if inter-individual variability in the diet inferred by feather isotopes could be explained by habitat use in winter as determined by satellite telemetry and examined possible carry-over effects on reproduction. Seventeen breeding female snowy owls were equipped with satellite transmitters and sampled for stable isotopes (δ13C and δ15N) in feathers. We found a positive relationship between the use of the coastal and marine environments in winter and the contribution of marine resources to the diet of snowy owls in the previous year based on feather analysis. The proportion of marine contribution to the winter diet was variable among individuals and showed a weak negative relationship to summer body mass but not with laying date or clutch size. Our integrated approach shows the usefulness of isotope analyses to infer habitat use and expand the temporal coverage of radio-tracking studies.
