description: Long Period Variable stars are ubiquitous among the bright red giant branch stars in NGC 5128. Mostly they are found to be brighter than the tip of the first ascent giant branch with magnitudes ranging from about K=19 to K=21.5. They have periods between 155 and 1000 days and K-band amplitudes between 0.1 and 2 mag, characteristic of semi-regular and Mira variables. We compare the colors, periods and amplitudes of these variables with those found in old stellar populations like Galactic globular clusters and Galactic bulge as well as with intermediate-age Magellanic Cloud long period variables. The population of stars above the tip of the red giant branch (RGB) amounts to 2176 stars in the outer halo field (Field 1) and 6072 stars in the inner halo field (Field 2). The comparison of the luminosity functions of the Galactic bulge, M31 bulge and NGC 5128 halo fields shows an excess of bright AGB stars extending to M_K ~ -8.65. The large majority of these sources belong to the asymptotic giant branch (AGB) population in NGC 5128. Subtracting the foreground Galactic stars and probable blends, at least 26% and 70% of AGB stars are variable in Fields 1 and 2, respectively. The average period of NGC 5128 LPVs is 395 days and the average amplitude 0.77 mag. Many more short period Miras are present in Field 2 than in Field 1 indicating a difference in the stellar populations between the two fields. Period and amplitude distributions and near-IR colors of the majority of LPVs in NGC 5128 are similar to the Galactic bulge variables. However, some ~10% of LPVs have periods longer than 500 days and thus probably more massive, hence younger, progenitor stars. A few carbon star candidates are identified based on their red J-H and H-K colors.

Data sharing and citation practices: An application of the theory of planned behaviour to social science research practice
Creators: name: Mceachern, Steven

Publisher: name: Zenodo
Year: 2014

description: This paper will showcase the results of a recent project run by the Australian Data Archive that aims to better understand the data sharing and data citation behaviours and attitudes of Australian social science researchers both in Australia and internationally. We define these two behaviours as follows: a) data sharing: "the voluntary provision of information from one individual or institution to another for purposes of legitimate scientific research" (Boruch, 1985) b) data citation: "the practice of providing a reference to data in the same way as researchers routinely provide a bibliographic reference to outputs such as journal articles, reports and conference papers" (ANDS, 2011) Drawing on the theory of planned behaviour (Azjen, 1991), the study explores researchers' current and intended data sharing and data citation practices, attitudes towards each behaviour, and perceived social and institutional barriers and supports for data sharing and data citation within their organisation and discipline. The paper will present the results of the ADA survey, and compare with two recent US studies to explore cross-national similarities and differences in data sharing and citation behavior.
Importance of direct and indirect triggered seismicity

Year: 2003
Subjects: subject: Geophysics (physics.geo-ph)

description: Using the simple ETAS branching model of seismicity, which assumes that each earthquake can trigger other earthquakes, we quantify the role played by the cascade of triggered seismicity in controlling the rate of aftershock decay as well as the overall level of seismicity in the presence of a constant external seismicity source. We show that, in this model, the fraction of earthquakes in the population that are aftershocks is equal to the fraction of aftershocks that are indirectly triggered and is given by the average number of triggered events per earthquake. Previous observations that a significant fraction of earthquakes are triggered earthquakes therefore imply that most aftershocks are indirectly triggered by the mainshock.

Testing anisotropic Hubble expansion

description: The cosmological principle asserting the large-scale uniformity of the Universe is a testable assumption of the standard cosmological model. We explore the constraints on anisotropic expansion provided by measuring directional variation in the Hubble constant, $H_0$, derived from differential zeropoint measurements of the Tully-Fisher distance estimator. We fit various models for directional variation in $H_0$ using the Tully-Fisher dataset from the all-sky Cosmicflows-4 catalog. The best-fit dipole variation has an amplitude of 0.063 $\pm$ 0.016 mag in the direction ($\ell,b$) = (142 $\pm$ 30$^{\circ}$, 52 $\pm$ 10$^{\circ}$). If this were due to anisotropic expansion it would imply a 3% variation in $H_0$, corresponding to $ΔH_0$ = 2.10 $\pm$ 0.53 km/s/Mpc if $H_0$ = 70 km/s/Mpc, with a significance of 3.9$σ$. A model that includes this $H_0$ dipole is only weakly favored relative to a model with a constant $H_0$ and a bulk motion of the volume sampled by Cosmicflows-4 that is consistent with the standard $Λ$CDM cosmology. However, we show that with the expected Tully-Fisher data from the WALLABY and DESI surveys it should be possible to detect a 1% $H_0$ dipole anisotropy at 5.8$σ$ confidence and to distinguish it from the typical bulk flow predicted by $Λ$CDM over the volume of these surveys.
Local Properties of the Potential Energy Landscape of a Model Glass: Understanding the Low Temperature Anomalies

description: Though the existence of two-level systems (TLS) is widely accepted to explain low temperature anomalies in the sound absorption, heat capacity, thermal conductivity and other quantities, an exact description of their microscopic nature is still lacking. We performed computer simulations for a binary Lennard-Jones system, using a newly developed algorithm to locate double-well potentials (DWP) and thus two-level systems on a systematic basis. We show that the intrinsic limitations of computer simulations like finite time and finite size problems do not hamper this analysis. We discuss how the DWP are embedded in the total potential energy landscape. It turns out that most DWP are connected to the dynamics of the smaller particles and that these DWP are rather localized. However, DWP related to the larger particles are more collective.
Cultural humility and therapeutic relationships (Scott, 2024)

description: Purpose: There is a significant racial, ethnic, and linguistic gap in professional representation in the field of speech-language pathology as compared to the rapidly diversifying special education student population, and this incongruence could have implications for the therapeutic relationship. The purpose of this article is to explore how school-based speech-language pathologists (SLPs) describe and define facilitating and impeding factors for establishing therapeutic relationships with culturally and linguistically diverse (CLD) students.Method: In this qualitative descriptive study, 17 school-based SLPs completed individual semistructured interviews. To enhance the trustworthiness of the study, six interview participants engaged in two member-checking focus groups, voting on the extent to which they agreed with the themes, and expanded on those themes with examples. A hybrid inductive–deductive thematic analysis was used to analyze the interview and focus group data.Results: Sixteen of the 17 school-based speech-language pathology participants represent racially/ethnically marginalized backgrounds; therefore, results are influenced by their lived experiences. Three themes emerged describing the nature of therapeutic relationships: critical components of therapeutic relationships, the strength of therapeutic relationships, and the therapeutic relationship as empowerment for CLD students. Four themes emerged to describe the factors facilitating and impeding therapeutic relationships: most valuable personality traits for SLPs, critical demand for speech-language pathology education, lacking cultural humility and rapport, and fostering relationships with cultural humility and rapport.Conclusions: School-based SLPs build and maintain therapeutic relationships with CLD students with cultural humility and rapport.

description: An e-graph efficiently represents a congruence relation over many expressions. Although they were originally developed in the late 1970s for use in automated theorem provers, a more recent technique known as equality saturation repurposes e-graphs to implement state-of-the-art, rewrite-driven compiler optimizations and program synthesizers. However, e-graphs remain unspecialized for this newer use case. Equality saturation workloads exhibit distinct characteristics and often require ad-hoc e-graph extensions to incorporate transformations beyond purely syntactic rewrites. This work contributes two techniques that make e-graphs fast and extensible, specializing them to equality saturation. A new amortized invariant restoration technique called rebuilding takes advantage of equality saturation's distinct workload, providing asymptotic speedups over current techniques in practice. A general mechanism called e-class analyses integrates domain-specific analyses into the e-graph, reducing the need for ad hoc manipulation. We implemented these techniques in a new open-source library called egg. Our case studies on three previously published applications of equality saturation highlight how egg's performance and flexibility enable state-of-the-art results across diverse domains.

Chasing the research question with data: The development of a data assignment for undergraduates
Creators: name: Katharin Peter
Publisher: name: Zenodo
Year: 2014

description: For many students, the Library's contribution to the research process begins and ends with the literature review. In these cases, librarians might assist students with pre-defined research questions or broad research topics to locate existing literature, primary sources, and data. However, as studies have shown, students often struggle with the first step of research: developing a viable question. This presents a unique opportunity for librarians and, especially, data librarians to provide guidance while at the same time supporting campus-wide initiatives to improve critical thinking, quantitative reasoning, and information literacy skills. Specifically, a small, data-based assignment for undergraduates could be employed to help students identify a research question. This paper will present the results of a series of pilot projects in which undergraduate international relations students were tasked with developing research proposals based on exploratory analyses of statistical databases from international and non-governmental organizations. The paper will discuss the development, outcomes, and assessment of data assignments piloted over the past two years and including traditional lectures, hands-on data labs, and online modules.

description: We re-analyse meson sector data from the CP-PACS collaboration's dynamical simulations. Our analysis uses several different approaches, and compares the standard naive linear fit with the Adelaide Anzatz. We find that setting the scale using the J parameter gives remarkable agreement among data sets. Our predictions for the rho and phi masses have very small statistical errors, ~ 3 MeV, but the discrepancy between the different fitting approaches is ~ 40 MeV.

description: In this session I will demonstrate the restricted access research computing infrastructure (CRADC- Cornell Restricted Access Data Center) that CISER (Cornell Institute of Social and Economic Research) has built to serve Cornell social science researchers and their collaborators worldwide. Based upon a local private-cloud service running on state-of-the-art computing systems that provides researchers (individual or teams) an environment where they can perform basic-to-complex highly secure computing tasks. The private-cloud service is accessible via remote access according to the researcher's data provider agreement. In this presentation I will show how and why CRADC's clientele continues to grow exponentially; discuss compliancy, regulations and standards based upon a specific data provider agreement; and review the need for continuous monitoring. Topics will additionally provide a description of the infrastructure, the value of shared economies of scale, the straightforward access to restricted data, and the administration/support services required to keep CRADC known as "the gateway to restricted data" at Cornell University.
On rare core collapse supernovae inside planetary nebulae

description: We conduct simulations using MESA of the reverse formation of a white dwarf (WD)-neutron star (NS) binary system in which the WD forms before the NS. We conclude that a core collapse supernova (CCSN) explosion might occur inside a planetary nebula (PN) only if a third star forms the PN. In this WD-NS reverse binary evolution, the primary star evolves and transfers mass to the secondary star, forms a PN, and leaves a WD remnant. If the mass-transfer brings the secondary star to have a mass of >8Mo before it develops a helium core, and if the secondary does not suffer an enhanced mass-loss before it develops a massive helium core, e.g., by mass-transfer, it explodes as a CCSN and leaves a NS remnant. The time period from the formation of the PN by the primary to the explosion of the secondary is >10^6 year. By that time the PN has long dispersed into the interstellar medium. In a binary system with nearly equal mass components, the first mass-transfer episode takes place after the secondary star has developed a helium core and it ends its life forming a PN and a WD. The formation of a CCSN inside a PN (CCSNIP) requires the presence of a third star. The third star should be less massive than the secondary star but by no more than few times 0.01Mo. We estimate that the rate of CCSNIP is ~10^{-4} times the rate of all CCSNe.

description: In this paper, we develop the James–Stein improved method for the estimation problem of a nonparametric periodic function observed with Lévy noises in continuous time. An adaptive model selection procedure based on the weighted improved least squares estimates is constructed. The improvement effect for nonparametric models is studied. It turns out that in non-asymptotic setting the accuracy improvement for nonparametric models is more important than for parametric ones. Moreover, sharp oracle inequalities for the robust risks have been shown and the adaptive efficiency property for the proposed procedures has been established. The numerical simulations are given.

Children, Mutts, Tributes : Reading Trauma in Fan Art of "The Hunger Games"
Creators: name: Bond, Chloe
Publisher: name: The University of British Columbia
Year: 2024

description: Against a backdrop of hyperconnectivity and myriad geopolitical crises, young people are consistently being exposed to increasingly violent images. YA trauma narratives can serve as learning spaces and sociocultural models to help them respond to such materials in productive, healthy ways. An increasing body of research has also highlighted that fan art, which engages in "remixing" and "restorying" practices, can function as a meaningful form of activism and offer us a window into young people's lives. Using responses to Suzanne Collins' The Hunger Games trilogy as a case study, this project aims to answer the following research question: what can 'reading' fan art tell us about how young people conceptualise trauma, specifically PTSD?
Seyfert galaxies: Nuclear Radio Structure and Unification

Subjects: subject: Astrophysics (astro-ph)

description: We have observed a sample of Seyfert (Sy) galaxies with the global Very Long Baseline Interferometry (VLBI) to test the predictions of the unification scheme for the Sy galaxies which hypothesises that Sys of Type 1 and of Type 2 constitute a single population of objects. If Sy 1 and Sy 2 galaxies differ only in the orientation of the axisymmmetric active nucleus with respect to the observer, then, the parsec scale radio structures of the two types should be similar. The overall goal of the thesis is to rigorously test the predictions of the unified scheme hypothesis for the Sy galaxies. We chose a sample of 10 Sy 1s and 10 Sy 2s such that the two subsamples were intrinsically similar within the framework of the unified scheme. This was done by matching them as far as possible in the orientation-independent parameters {\it viz.}, host galaxy properties and measures of intrinsic Active Galactic Nuclei (AGN) power. We here present the results obtained from these observations and their implications on the unification scheme. We also discuss the results obtained from the measurements at all IRAS and 2-10 keV X-ray wavebands for our Sy galaxy sample using data from the literature.

Differential Rotation in Convective Envelopes: Constraints from Eclipsing Binaries

description: Over time, tides synchronize the rotation periods of stars in a binary system to the orbital period. However, if the star exhibits differential rotation then only a portion of it can rotate at the orbital period, so the rotation period at the surface may not match the orbital period. The difference between the rotation and orbital periods can therefore be used to infer the extent of the differential rotation. We use a simple parameterization of differential rotation in stars with convective envelopes in circular orbits to predict the difference between the surface rotation period and the orbital period. Comparing this parameterization to observed eclipsing binary systems, we find that in the surface convection zones of stars in short-period binaries there is very little radial differential rotation, with $|r\partial_r \ln Ω| < 0.02$. This holds even for longer orbital periods, though it is harder to say which systems are synchronized at long periods, and larger differential rotation is degenerate with asynchronous rotation.

An Object-Oriented Minimization Package for HEP

description: A portion of the HEP community has perceived the need for a minimization package written in C++ and taking advantage of the Object-Oriented nature of that langauge. To be acceptable for HEP, such a package must at least encompass all the capabilities of Minuit. Aside from the slight plus of not relying on outside Fortran compilation, the advantages that a C++ package based on O-O design would confer over the multitude of available C++ Minuit-wrappers include: Easier extensibility to different algorithms and forms opf constraints; and usage modes which would not be available in the global-common-based Minuit design. An example of the latter is a job persuing two ongoing minimization problems simultaneously. We discuss the design and implementation of such a package, which extends Minuit only in minor ways but which greatly diminishes the programming effort (if not the algorithm thought) needed to make more significant extensions.

The Liberating Potential of Social Media in the Philippine Context

Social Media

description: Abstract This qualitative study on the liberating potential of social media in the Philippines used the Grounded Theory design which utilized information from the ground to come up with a developing theory that describes an evolving phenomenon involving the Filipino's way of navigating the sphere of virtual communication. The findings in this study were anchored on a well-represented cross section of the population in terms of generation, gender, social status and experiences. It utilized the linear snowball sampling which resulted in 10 participants who contributed in the making of meaning. The research questions revolved around social media and the shape of this phenomenon in the Philippine context and whether it indeed enabled individuals and communities to overcome their sense of powerlessness and lack of influence, take advantage of the blurring of borders and thus achieve personal and social liberation. The resulting theory is the Theory of Virtual Deliverance which posits that social media has become a contemporary liberating tool that is potentially effective in addressing social ills in acceptable ways that somehow manage to circumvent existing structures, specifically in a community like the Philippines where they tend to be perceived as unequal, discriminatory and oppressive. Participant accounts support that the Filipino's notion of liberation is the very definition of deliverance mentioned as 'kaluwasan', which is the action of being rescued and set free in a way that involves faith and an effort to overcome fate. The virtual space that social media offers has somehow provided a redefined leverage not only to those with means but especially to those who have very little leverage in their actual physical space.

description: We propose time-varying coefficient mixed-effects models for continuous multiple time series data and longitudinal data. The challenge is how to simultaneously display serial, clustering, and multivariate attributes of the data set, to which the routinely assumed two-level hierarchical model and univariate response models are not able to apply. Asymptotic properties of the proposed methods are established. We also conduct the model comparison, and find that the proposed methods outperform the traditional univariate response models, nonparametric models, and linear mixed effects models in both predicting the response and estimating the coefficient surface based on simulation studies. Finally, we have applied our methods to a real-world study on the price–volume relationship of NASDAQ stock market data.

description: For a nonsingular integer matrix A, we study the growth of the order of A modulo N. We say that a matrix is exceptional if it is diagonalizable, and a power of the matrix has all eigenvalues equal to powers of a single rational integer, or all eigenvalues are powers of a single unit in a real quadratic field. For exceptional matrices, it is easily seen that there are arbitrarily large values of N for which the order of A modulo N is logarithmically small. In contrast, we show that if the matrix is not exceptional, then the order of A modulo N goes to infinity faster than any constant multiple of log N.

description: Using the results from the 2012 DLI (Data Liberation Initiative) Contacts Survey, I will paint a picture of someone who is a data dude, aka data librarian or data specialist, in a Canadian university or college. A background of the survey will be reviewed briefly, followed by a description of what the data profession in 2012 entailed, including: the amount of time spent offering data services; the frequency of data-related questions; the type of instruction-related activities; what other job duties are performed; the level of confidence in helping others with data; where do data dudes go to get help with data; and whether or not they receive regular professional development. Suggestions for a picture of a Canadian data dude in the future will be given.

description: In this note, we consider the situation where we have a functional predictor as well as some more traditional scalar predictors, which we call the partially functional problem. We propose a semiparametric model based on sufficient dimension reduction, and thus our main interest is in dimension reduction although prediction can be carried out at a second stage. We establish root-n consistency of the linear part of the estimator. Some Monte Carlo studies are carried out as proof of concept.

description: Recent observations of neutron stars with gravitational waves and X-ray timing provide unprecedented access to the equation of state (EoS) of cold dense matter at densities difficult to realize in terrestrial experiments. At the same time, predictions for the EoS with reliable uncertainty estimates from chiral effective field theory ($χ$EFT) bound our theoretical ignorance. In this work, we analyze astrophysical data using a nonparametric representation of the neutron-star EoS conditioned on $χ$EFT to directly constrain the underlying physical properties of the compact objects. We discuss how the data alone constrain the EoS at high densities when we condition on $χ$EFT at low densities. We also demonstrate how to exploit astrophysical data to directly test the predictions of $χ$EFT for the EoS up to twice nuclear saturation density, and estimate the density at which these predictions might break down. We find that the existence of massive pulsars, gravitational waves from GW170817, and NICER observations of PSR J0030+0451 favor $χ$EFT predictions for the EoS up to nuclear saturation density over a more agnostic analysis by as much as a factor of 7 for the quantum Monte Carlo (QMC) calculations used in this work. While $χ$EFT predictions using QMC are fully consistent with gravitational-wave data up to twice nuclear saturation density, NICER observations suggest that the EoS stiffens relative to these predictions at nuclear saturation density. Additionally, we marginalize over the uncertainty in the density at which $χ$EFT begins to break down, constraining the radius of a $1.4\,M_\odot$ neutron star to $R_{1.4}=11.40^{+1.38}_{-1.04}$ ($12.54^{+0.71}_{-0.63}$) km and the pressure at twice nuclear saturation density to $p(2n_\mathrm{sat})=14.2^{+18.1}_{-8.4}$ ($28.7^{+15.3}_{-15.0}$) MeV/fm$^3$ with massive pulsar and gravitational-wave (and NICER) data.

description: We show that the complicated *-structure characterizing for positive q the U_qso(N)-covariant differential calculus on the non-commutative manifold R_q^N boils down to similarity transformations involving the ribbon element of a central extension of U_qso(N) and its formal square root v. Subspaces of the spaces of functions and of p-forms on R_q^N are made into Hilbert spaces by introducing non-conventional ``weights'' in the integrals defining the corresponding scalar products, namely suitable positive-definite q-pseudodifferential operators realizing the action of v^{\pm 1}; this serves to make the partial q-derivatives antihermitean and the exterior coderivative equal to the hermitean conjugate of the exterior derivative, as usual. There is a residual freedom in the choice of the weight m(r) along the `radial coordinate' r. Unless we choose a constant m, then the square-integrables functions/forms must fulfill an additional condition, namely their analytic continuations to the complex r plane can have poles only on the sites of some special lattice. Among the functions naturally selected by this condition there are q-special functions with `quantized' free parameters.

description: The local current flow through three small aromatic carbon molecules, namely benzene, naphthalene and anthracene, is studied. Applying density functional theory and the non-equilibrium Green's function method for transport, we demonstrate that pronounced current vortices exist at certain electron energies for these molecules. The intensity of these circular currents, which appear not only at the anti-resonances of the transmission but also in vicinity of its maxima, can exceed the total current flowing through the molecular junction and generate considerable magnetic fields. The $π$ electron system of the molecular junctions is emulated experimentally by a network of macroscopic microwave resonators. The local current flows in these experiments confirm the existence of current vortices as a robust property of ring structures. The circular currents can be understood in terms of a simple nearest-neighbor tight-binding Hückel model. Current vortices are caused by the interplay of the complex eigenstates of the open system which have energies close-by the considered electron energy. Degeneracies, as observed in benzene and anthracene, can thus generate strong circular currents, but also non-degenerate systems like naphthalene exhibit current vortices. Small imperfections and perturbations can couple otherwise uncoupled states and induce circular currents.

description: We investigate localization properties in a two-coupled uniform chains with quasiperiodic modulation on interchain coupling strength. We demonstrate that this ladder is equivalent to a Aubry-Andre (AA) chain when two legs are symmetric. Analytical and numerical results indicate the appearance of mobility edges for asymmetric ladder. We also propose an easily engineered quasiperiodic ladder system which is a moiré superlattice system consisting of two-coupled uniform chains. An irrational lattice constant difference results in quasiperiodic structure. Numerical simulations show that such a system supports mobility edge. Additionally, we find that the mobility edge can be detected by a dynamic method, which bases on the measurement of surviving probability in the presence of a single imaginary negative potential as a leakage. The result provides insightful information about the localization transitions and mobility edge in experiment.
Global parametrizations of $ππ$ scattering with dispersive constraints: Beyond the S0 wave

description: We provide new global parametrizations of $ππ\to ππ$ scattering for the S2, P, D, F, and G partial waves up to at least 1.8 GeV, easy to implement for phenomenological use. With earlier S0-wave parametrizations, slightly updated here, they reproduce previous partial wave dispersion analyses up to the $πω$ threshold. In addition, these new parametrizations have improved their description of recent P-wave data, the inelasticity in various waves, and their fulfillment of Roy-like and forward dispersion relations. The latter now test very high partial waves and have an improved matching with the Regge regime, extending those with P-wave contributions up to 1.6 GeV. Above 1.6 GeV and up to 1.8 GeV, or sometimes somewhat beyond, the parametrizations are simple unconstrained fits to data.
