description: Contracting tensor networks is often computationally demanding. Well-designed contraction sequences can dramatically reduce the contraction cost. We explore the performance of simulated annealing and genetic algorithms, two common discrete optimization techniques, to this ordering problem. We benchmark their performance as well as that of the commonly-used greedy search on physically relevant tensor networks. Where computationally feasible, we also compare them with the optimal contraction sequence obtained by an exhaustive search. We find that the algorithms we consider consistently outperform a greedy search given equal computational resources, with an advantage that scales with tensor network size. We compare the obtained contraction sequences and identify signs of highly non-local optimization, with the more sophisticated algorithms sacrificing run-time early in the contraction for better overall performance.

description: Across Canada, ten universities (to date) have worked together to survey their research communities in order to better understand research data management practices and needs. This work builds on a previous collaborative effort designed to delve into RDM habits of researchers in engineering and science, by expanding to researchers in the humanities and social sciences. This session will discuss the survey results from participating universities, providing insight into the Canadian RDM landscape while highlighting disciplinary differences and notable results. Survey sections include working with research data, data sharing, funding mandates and research data management services. Information generated by this survey will help inform Canadian institutional services, infrastructure and policies. Participating universities at the time of writing include: Dalhousie University, McGill University, Queen's University, Ryerson University, University of Alberta, University of British Columbia, University of Ottawa, University of Toronto, University of Waterloo, and the University of Windsor. The session will also discuss the collaboration process, which resulted in the development of a clearinghouse of generic survey documents (questionnaires, ethics review documents) that will be housed by Portage, Canada's emerging national RDM infrastructure project. These documents can be used by other institutions to conduct similar studies. Future initiatives include a further survey of researchers in the health and medical sciences.Additional authors arenbsp;Marjorie Mitchell,nbsp;University of British Columbia andnbsp;Matthew Gertler,nbsp;University of Toronto.

description: The study of nuclei at finite temperature is of immense interest for many areas of nuclear astrophysics and nuclear-reaction science. A variety of ab initio methods are now available for computing the properties of nuclei from interactions rooted in Quantum Chromodynamics, but applications have largely been limited to zero temperature. In the present work, we extend one such method, the In-Medium Similarity Renormalization Group (IMSRG), to finite temperature. Using an exactly-solvable schematic model that captures essential features of nuclear interactions, we show that the FT-IMSRG can accurately determine the energetics of nuclei at finite temperature, and we explore the accuracy of the FT-IMSRG in different parameter regimes, e.g., strong and weak pairing. In anticipation of FT-IMSRG applications for finite nuclei and infinite matter, we discuss differences arising from the choice of working with the canonical and the grand canonical ensembles. In future work, we will apply the FT-IMSRG with realistic nuclear interactions to compute nuclear structure and reaction properties at finite temperature, which are important ingredients for understanding nucleosynthesis in stellar environments, or modeling reactions of hot compound nuclei.

description: Recent studies of the detectability of cosmic topology of nearly flat universes have often concentrated on the range of values of $Ω_{0}$ given by current observations. Here we study the consequences of taking the bounds on $Ω_{0}$ given by inflationary models, i.e. $|Ω_0 - 1| \ll 1$. We show that in this limit, a generic detectable non-flat manifold is locally indistinguishable from either a cylindrical ($R^2 \times S^1$) or toroidal ($R \times T^2$) manifold, irrespective of its global shape, with the former being more likely. Importantly this is compatible with some recent indications based on the analysis of high resolution CMB data. It also implies that in this limit an observer would not be able to distinguish topologically whether the universe is spherical, hyperbolic or flat. By severely restricting the expected topological signatures of detectable isometries, our results provide an effective theoretical framework for interpreting cosmological observations, and can be used to confine any parameter space which realistic search strategies, such as the `circles in the sky' method, need to concentrate on. This is particularly important in the inflationary limit, where the precise nature of cosmic topology becomes undecidable.

Horns of subaqueous barchan dunes: A study at the grain scale

description: Many complex aspects are involved in the morphodynamics of crescent-shaped dunes, known as barchans. One of them concerns the trajectories of individual grains over the dune, and how they affect its shape. In the case of subaqueous barchans, we proposed in Alvarez and Franklin [Phys. Rev. Lett. 121, 164503 (2018)] that their extremities, called horns, are formed mainly by grains migrating from upstream regions of the initial pile, and that they exhibit significant transverse displacements. Here, we extend our previous work to address the dynamics of grains migrating to horns after the dune has reached its crescentic shape, and present new aspects of the problem. In our experiments, single barchans evolve, under the action of a water turbulent flow, from heaps of conical shape formed from glass beads poured on the bottom wall of a rectangular channel. Both for evolving and developed barchans, the horns are fed up with grains coming from upstream regions of the bedform and traveling with significant transverse components, differently from the dynamics usually described for the aeolian case. For these grains, irrespective of their size and strength of water flow, the distributions of transverse and streamwise components of velocities are well described by exponential functions, with the probability density functions of their magnitudes being similar to results obtained from previous studies on flat beds. Focusing on moving grains whose initial positions were on the horns, we show that their residence time and traveled distance are related following a quasi-linear relation. Our results provide new insights into the physical mechanisms underlying the shape of barchan dunes.

description: This poster presents the results of a student research project (Master in Information Science of HEG, HES-SO) performed in the frame of the consulting, training and teaching activities of the Swiss DLCM project. This work is dedicated to designing one or several e-learning models for the DLCM context. We first make an inventory of the e-learning resources in RDM already made available by Swiss and foreign institutions. This review allows us to set up a typology of e-learning resources in GDR and to identify some reusable and adaptable material for the DLCM e-learning course. The creation and the development of an e-learning course should follow a step-by-step process: analyse, design, test, produce, follow-up, which we adapt to the project environment and describe in detail. E-learning courses may take a whole variety of configurations, according to choices made among (to give only a few examples): hybrid course or full distant learning, free access or not, delivery of a certificate or not, tutored course or not; and to related questions such as: how much tutoring? By which means? etc. We discuss each element of configuration and make recommendations for the project specific context. Basing on typical profiles of the DLCM course audience and on an assessment of their needs, we suggest three options of training configurations: SPOC, MOOC and free training course.

description: Two-photon exchange contributions to elastic electron-proton scattering cross sections are evaluated in a simple hadronic model including the finite size of the proton. The corrections are found to be small in magnitude, but with a strong angular dependence at fixed $Q^2$. This is significant for the Rosenbluth technique for determining the ratio of the electric and magnetic form factors of the proton at high $Q^2$, and partly reconciles the apparent discrepancy with the results of the polarization transfer technique.

description: It is commonly accepted that clinicians are ethically obligated to disclose their use of medical machine learning systems to patients, and that failure to do so would amount to a moral fault for which clinicians ought to be held accountable. Call this "the disclosure thesis." Four main arguments have been, or could be, given to support the disclosure thesis in the ethics literature: the risk-based argument, the rights-based argument, the materiality argument, and the autonomy argument. In this article, I argue that each of these four arguments are unconvincing, and therefore, that the disclosure thesis ought to be rejected. I suggest that mandating disclosure may also even risk harming patients by providing stakeholders with a way to avoid accountability for harm that results from improper applications or uses of these systems.

description: Tensor reduction is important for multi-loop amplitude calculation. And the projection method is one of the most popular approaches for tensor reduction. However, projection method could be problematic for amplitude with massive fermions due to the inconsistency between helicity and chirality. We propose an approach to extend the projection method to reduce the loop amplitude containing fermion chain with two massive spinors. The extension is achieved by decomposing one of the massive spinors into two specific massless spinors, "null spinor" and "reference spinor". Then the extended projection method can be safely implemented for all the processes including the production of massive fermions. Finally we present the tensor reduction for the virtual Z boson decaying to top-quark pair to demonstrate our approach.

description: In June 2016 the Tri-Council Agencies, a major source of research funding for post-secondary institutions in Canada, released a Statement of Principles on Digital Data Management which identifies research data management (RDM) as being an essential and shared responsibility between researchers, research communities, research institutions, and research funders. As a major international research library, University of Alberta Libraries (UAL) offers expertise, resources, and services for supporting sound RDM throughout the research lifecycle. In alignment with the Tri-Council statement, UAL has adopted a holistic approach to education and delivering of RDM knowledge and resources across campus, focusing upon a variety of stakeholders. Examples of this include a running series of applied RDM training sessions for liaison librarians, customized information sessions both for Research Services Office and Research Ethics Office staff, and collaborative RDM events and training sessions delivered to researchers and students across campus. Some specific services and platforms offered by UAL include the Portage Data Management Planning (DMP) Assistant, Dataverse, and an open access Education and Research Archive for promoting research discovery, archival, and preservation. This session will provide a brief overview of UAL's RDM services, methods employed for their delivery and uptake, and both current and emerging RDM initiatives.

[dis]placed : a humanitarian design approach to refugee crisis
Creators: name: Gorgulicten, Begum
Publisher: name: The University of British Columbia
Year: 2023

description: Refugees are among the most marginalized populations in Canada, whose living conditions are worsened by the fact that they scatter throughout the country to access housing that they can afford, pursue economic opportunities to sustain their families, and preserve their cultural integrity in the face of social isolation. This project contemplates how architecture can help instigate a systemic change in refugees’ transition from their lives in their home countries to their new lives in Vancouver. Taking a radical incrementalist approach to humanitarian architecture, this project aims to utilize architecture to set a model that acts as a facilitator for cultural interactions and opportunities both on urban and building scales.
Towards Transferable Adversarial Attack against Deep Face Recognition

Year: 2020
Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)

description: Face recognition has achieved great success in the last five years due to the development of deep learning methods. However, deep convolutional neural networks (DCNNs) have been found to be vulnerable to adversarial examples. In particular, the existence of transferable adversarial examples can severely hinder the robustness of DCNNs since this type of attacks can be applied in a fully black-box manner without queries on the target system. In this work, we first investigate the characteristics of transferable adversarial attacks in face recognition by showing the superiority of feature-level methods over label-level methods. Then, to further improve transferability of feature-level adversarial examples, we propose DFANet, a dropout-based method used in convolutional layers, which can increase the diversity of surrogate models and obtain ensemble-like effects. Extensive experiments on state-of-the-art face models with various training databases, loss functions and network architectures show that the proposed method can significantly enhance the transferability of existing attack methods. Finally, by applying DFANet to the LFW database, we generate a new set of adversarial face pairs that can successfully attack four commercial APIs without any queries. This TALFW database is available to facilitate research on the robustness and defense of deep face recognition.

description: We reassess the applicability of the Toomre criterion in galactic disks and we study the local star formation law in 16 disk galaxies for which abundance gradients are published. The data we use consists of stellar light profiles, atomic and molecular gas (deduced from CO with a metallicity-dependent conversion factor), star formation rates (from H-alpha emissivities), metallicities, dispersion velocities and rotation curves. We show that the Toomre criterion applies successfully to the case of the Milky Way disk, but it has limited success with the data of our sample; depending on whether the stellar component is included or not in the stability analysis, we find average values for the threshold ratio of the gas surface density to the critical surface density in the range 0.5 to 0.7. We also test various star formation laws proposed in the literature, i.e. either the simple Schmidt law or modifications of it, that take into account dynamical factors. We find only small differences among them as far as the overall fit to our data is concerned; in particular, we find that all three SF laws (with parameters derived from the fits to our data) match particularly well observations in the Milky Way disk. In all cases we find that the exponent n of our best fit SFR has slightly higher values than in other recent works and we suggest several reasons that may cause that discrepancy.

description: The task of experimentally investigating the inherently dual properties of a supersolid, a simultaneous superfluid and solid, has become more critical following the recent experimental exploration of supersolid regimes in dipolar Bose-Einstein condensates (BECs) of $^{164}\text{Dy}$. We introduce a supersolid order parameter that uses vortex-vortex trajectory correlations to simultaneously reveal the periodic density of the underlying solid and superfluidity in a single measure. We propose experiments using existing technology to optically create and image trajectories of vortex dipoles in dipolar BECs that is applicable to large system sizes. We numerically test our observable and find that vortex-vortex correlations reveal the supersolid lattice structure while distinguishing it from superfluidity even in the presence of dissipation. Our method sets the stage for experiments to use vortex trajectory correlations to investigate fundamental properties of supersolids arising from their dynamics and phase transitions as experimental system sizes are increased.

description: The presentation draws on a use case from political science to demonstrate integrated scholarly processes for curating and publishing data. Curation activities are distributed across institutional and national repositories, archives, registries and websites. In workflows which prioritise existing research practice and disciplinary standards, researchers provide structured metadata to the Australian Data Archive (ADA) using a template based on the Data Documentation Initiative (DDI). These metadata are mapped to RDF and RIF-CS standards and sent to the institutional repository at UNSW Australia, for publication and further dissemination. The primary role of the institutional repository is to move the data around – to apply standards and protocols that enable the data to be widely and openly accessible.The implementation supports researchers in comprehensively describing their research methods and data according to a widely-adopted disciplinary standard, and reduces their workload relating to institutional reporting and dissemination. The integrity of the institutional data repository is increased by its direct integration with the rich descriptions of data in the disciplinary archive. Added value for the institution is derived from the reporting capabilities of the repository, which links to enterprise systems to generate statistics about the University's research assets.

description: We present the first SkyMapper stellar population analysis of the Large Magellanic Cloud (hereafter LMC),including the identification of 3578 candidate Carbon Stars through their extremely red $g-r$ colours. Coupled with Gaia astrometry, we analyse the distribution and kinematics of this Carbon Star population, finding the LMC to be centred at $(R.A., Dec.) = (80.90^{\circ}\pm{0.29}, -68.74^{\circ}\pm{0.12})$, with a bulk proper motion of $(μ_α,μ_δ) = (1.878\pm0.007,0.293\pm0.018) \mathrm{mas\ yr^{-1}}$ and a disk inclination of $i = 25.6^{\circ}\pm1.1$ at position angle $θ= 135.6^{\circ}\pm 3.3^{\circ}$. We complement this study with the identification and analysis of additional stellar populations, finding that the dynamical centre for Red Giant Branch (RGB) stars is similar to that seen for the Carbon Stars, whereas for young stars the dynamical centre is significantly offset from the older populations. This potentially indicates that the young stars were formed as a consequence of a strong tidal interaction, probably with the Small Magellanic Cloud (SMC). In terms of internal dynamics, the tangential velocity profile increases linearly within $\sim3\ \mathrm{kpc}$, after which it maintains an approximately constant value of $V_{rot} = 83.6\pm 1.7 \mathrm{km\ s^{-1}}$ until $\sim7 \mathrm{kpc}$. With an asymmetric drift correction, we estimate the mass within $7 \mathrm{kpc}$ to be $M_{\rm LMC}(<7\mathrm{kpc}) = (2.5\pm0.1)\times10^{10}\ \mathrm{M}_{\odot}$ and within the tidal radius ($\sim 30\ \mathrm{kpc}$) to be $M_{\rm LMC}(<30\mathrm{kpc}) = (1.06 \pm 0.32)\times10^{11}\ \mathrm{M}_{\odot}$, consistent with other recent measurements.

description: We present a simple and reliable method for making electrical contacts to small organic molecules with thiol endgroups. Nanometer-scale gaps between metallic electrodes have been fabricated by passing a large current through a lithographically-patterned Au-line with appropriate thickness. Under appropriate conditions, the passage of current breaks the Au-line, creating two opposite facing electrodes separated by a gap comparable to the length of small organic molecules. Current-voltage characteristics have been measured both before and after deposition of short organic molecules. The resistance of single 1,4-benzenedithiol and 1,4-bezenedimethanedithiol molecules were found to be 9M$Ω$ and 26M$Ω$, respectively. The experimental results indicate strong electronic copuling to the contacts and are discussed using a relatively simple model of mesoscopic transport. The use of electrodes formed on an insulating surface by lithography and electromigration provides a stable structure suitable for integrated circuit applications.

description: We used Monte Carlo simulations to assess the performance of three bootstrap procedures for use with multilevel data (the parametric bootstrap, the residuals bootstrap, and the nonparametric bootstrap) for estimating the sampling variation of three measures of cluster variation and heterogeneity when using a multilevel logistic regression model: the variance of the distribution of the random effects, the variance partition coefficient (equivalent here to the intraclass correlation coefficient), and the median odds ratio. We also described a novel parametric bootstrap procedure to estimate the standard errors of the predicted cluster-specific random effects. Our results suggest that the parametric and residuals bootstrap should, in general, be used to estimate the sampling variation of key measures of cluster variation and heterogeneity. The performance of the novel parametric bootstrap procedure for estimating the standard errors of predicted cluster-specific random effects tended to exceed that of the model-based estimates.

description: Fluctuations of the color superconducting order parameter in dense quark matter at finite temperatures are investigated in terms of the phenomenological Ginzburg - Landau approach. Our estimates show that fluctuations of the di-quark gap may strongly affect some of thermodynamic quantities even far below and above the critical temperature. If the critical temperature of the di-quark phase transition were rather high one could expect a manifestation of fluctuations of the di-quark gap in the course of heavy ion collisions.

Consequently, many funders have implemented formal data management plans as part of the proposal process, while data repositories and libraries have developed services, guidelines and trainings to help researchers fulfill funders' requirements and apply good data management practices so that data can be shared. However, these same parties sometimes neglect the fact that many researchers do not take data management seriously, and perceive it and treat it at best as a form of administrative burden, and at worst as an obstacle to doing research. We will call for the repositioning of data management to the heart of the research process, irrespective of data sharing. Researchers should first and foremost see the value of good data management for their own research, as a way to achieve research excellence. We will share some reflections as to how this could be achieved by reconsidering the roles of funding agencies, data repositories, and librarians in encouraging and supporting good data management practices, beyond the goal of data sharing.

description: Recently, the Hamilton Monte Carlo (HMC) has become widespread as one of the more reliable approaches to efficient sample generation processes. However, HMC is difficult to sample in a multimodal posterior distribution because the HMC chain cannot cross energy barrier between modes due to the energy conservation property. In this paper, we propose a Stochastic Approximate Hamilton Monte Carlo (SAHMC) algorithm for generating samples from multimodal density under the Hamiltonian Monte Carlo (HMC) framework. SAHMC can adaptively lower the energy barrier to move the Hamiltonian trajectory more frequently and more easily between modes. Our simulation studies show that the potential for SAHMC to explore a multimodal target distribution is more efficient than HMC-based implementations.
Putting Metadata on the Map - Producing Enhanced Geospatial Visualisations from Open-source Tools to Encourage Metadata Creation Earlier in the Data Lifecycle

description: Librarians and archivists have long known the benefits of metadata in for improving discoverability and understanding of datasets. However, with some open-data portals when depositing guidelines are based on policy or legislative requirements metadata quality may be an additional burden for data depositors with lower concern for long-term archival strategies. What is needed is a way to demonstrate short-term benefits for depositors that improve metadata quality while reducing the perceived burden of metadata production.nbsp;To improve the quality of data and metadata records for data.gov.au, we explored methods to improve production of rich geospatial visualisations to show users the immediate benefit of structural metadata, while also showing how metadata improved the quality of deposited data records. Additionally, we offered minimal machine-readable metadata profiles that could be created in common office-suite tools to maximise utility while minimising authoring time.This talk covers the challenges of producing structural metadata from records available in the data.gov.au CKAN data repository, methods for importing this into an open-source Aristotle Metadata Registry and how we connected these to produce metadata-driven interactive maps on NationalMap using Terria.io. Lastly, we look at how this data-visualisation focus engagement strategy has improved the quality of open government data.
A Particle number conserving shell-correction method

Publisher: name: arXiv
Year: 2004
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: The shell correction method is revisited. Contrary to the traditional Strutinsky method, the shell energy is evaluated by an averaging over the number of particles and not over the single-particle energies, which is more consistent with the definition of the macroscopic energy. In addition, the smooth background is subtracted before averaging the sum of single-particle energies, which significantly improves the plateau condition and allows to apply the method also for nuclei close to the proton or neutron drip lines. A significant difference between the shell correction energy obtained with the traditional and the new method is found in particular for highly degenerated single-particle spectra (as i.e. in magic nuclei) while for deformed nuclei (where the degeneracy is lifted to a large extent) both estimates are close, except in the region of super or hyper-deformed states.

description: Vehicles are increasingly becoming connected and short-range wireless communications promise to introduce a radical change in the drivers' behaviors. Among the main use cases, the intersection management is surely one of those that could mostly impact on both traffic safety and efficiency. In this work, we consider an intersection collision warning application and exploit an hardware-in-the-loop (HIL) platform to verify the impact on the risk of accidents as well as the average time to travel a given distance. Besides including real ITS-G5 compliant message exchanges, the platform also includes a channel emulator with real signals. Results show that the risk of collisions can be drastically reduced, with an overall trade-off between safety and traffic efficiency. At the same time, it is shown that the presence of real channel conditions cannot guarantee the same condition of zero-risk as with ideal channel propagation, remarking the importance of channel conditions and signal processing.

Cosmic Acceleration Caused by the Extra-Dimensional Evolution in a Generalized Randall-Sundrum Model

description: We investigate a $(n+1)$-dimensional generalized Randall-Sundrum model with an anisotropic metric which has three different scale factors. One obtain a positive effective cosmological constant $Ω_{eff}\sim10^{-124}$ (in Planck unit) which only need a solution $kr\simeq50-80$ without fine tuning, and both the visible and hidden brane tensions are positive which results in the two branes to be stable. Then, we find that the Hubble parameter is seem to be a constant in a large region near its minimum, thus causing the acceleration of the universe. Therefore, the fine tuning problem also can be solved in this model. Meanwhile, the scale of extra dimensions is smaller than the observed scale but greater than the Planck length. This demonstrates that the observed present acceleration of the universe is caused by the extra-dimensional evolution rather than dark energy.

description: The interferometric data processing methods that we describe in this paper use a number of innovative techniques. In particular, the implementation of the wavelet transform allows us to obtain a good immunity of the fringe processing to false detections and large amplitude perturbations by the atmospheric piston effect, through a careful, automated selection of the interferograms. To demonstrate the data reduction procedure, we describe the processing and calibration of a sample of stellar data from the VINCI beam combiner. Starting from the raw data, we derive the angular diameter of the dwarf star Alpha Cen A. Although these methods have been developed specifically for VINCI, they are easily applicable to other single-mode beam combiners, and to spectrally dispersed fringes.
