channel recharge

description: In the Thompson-Fraser Rail Corridor in Interior British Columbia, the Canadian National (CN) rail line traverses several alluvial fans, which are subject to occasional debris flows. Debris flows pose a significant geohazard due to the combination of high flow velocities, large impact forces, long runout distances and poor temporal predictability. When a debris flow occurs, the cost of repairs, maintenance, and construction along these single-track railway lines is compounded by the fact that these activities also impede the flow of rail traffic, which has financial repercussions for the operators. As a result, it is vital to be able to identify and prioritize the slopes that pose the greatest hazard to the rail lines. A thorough understanding of the geohazards present on site is an essential component of risk assessment. The Canadian Railway Ground Hazard Research Program (RGHRP) was established in 2003 with the aim of better understanding the natural hazards impacting railway operations across Canada. The present study is part of this initiative and focuses on an active site called the White Canyon, which is located 275 kilometers northeast of Vancouver, BC. In this study, we use terrestrial laser scanning (TLS) and panoramic imagery datasets to analyze the debris recharge patterns that develop between debris flows in a select channel in the White Canyon. TLS scans taken before and after the events provide insight into the volumes of material mobilized and how we can leverage this series of TLS data to give insight into the amount of debris accumulating in the channels prior to failure. The temporal data acquisition rate was found to have a significant influence on the amount of movement that can be interpreted from the TLS change detection analysis and panoramic images. Therefore, the temporal data acquisition rate is key consideration when using TLS to support the determination of accurate return periods on debris flows.

Controlled Undoing : Rethinking the death of a corner store
Creators: name: Law, Ho Yun
Publisher: name: The University of British Columbia
Year: 2023

description: This thesis calls for a critical and poetic way of looking at architectural death. This thesis will establish its underlying premises, indicate the failings of the utilitarian attitude of obsolescence that leads to total demolition, and the superficial idea of heritage building conservation as method of treating death in architecture. It urges stakeholders to rethink how architecture is valued and how buildings should die, proposing an alternative end-of-life process- a controlled undoing, a practice of lengthening and slowing the death of a building, while creating an alternative approach to preserving histories, memories and intangible heritage. More specifically, a controlled undoing shall be seen as a collection of funeral rituals facilitated by the architect, in which architectural operations are performed to reveal memories and intangible cultural heritage. This collection of rituals shall allow the community to commemorate an obsolete building, creating a continuous flow of inheritance of the building’s legacy. This thesis travels back in time to the moment of death of BK Grocery, one of the disappearing corner stores in Vancouver, and speculates an alternative death through a funeral. With the examination of mortuary rituals from three cultures, this thesis explores the different concepts of death as an aid to the speculation. Through controlled undoing, this thesis attempts to strategically arrange the death of BK Grocery so that the needs of the neighbourhood community is maintained, facilitating emotional, historical, social, and environmental continuity, while preserving intangible values such as authentic culture, traditions, identities, and place.

description: Conflicting transactions within blockchain networks not only pose performance challenges but also introduce security vulnerabilities, potentially facilitating malicious attacks. In this paper, we explore the impact of conflicting transactions on blockchain attack vectors. Through modeling and simulation, we delve into the dynamics of four pivotal attacks - block withholding, double spending, balance, and distributed denial of service (DDoS), all orchestrated using conflicting transactions. Our analysis not only focuses on the mechanisms through which these attacks exploit transaction conflicts but also underscores their potential impact on the integrity and reliability of blockchain networks. Additionally, we propose a set of countermeasures for mitigating these attacks. Through implementation and evaluation, we show their effectiveness in lowering attack rates and enhancing overall network performance seamlessly, without introducing additional overhead. Our findings emphasize the critical importance of actively managing conflicting transactions to reinforce blockchain security and performance.

description: We present a holographic analysis of diffractive photoproducton of charmonium $J/ψ$ and upsilonium $Υ$ on a proton, considered as a bulk Dirac fermion, for all ranges of $\sqrt{s}$, i.e., from near threshold to very high energy. Using the bulk wave functions of the proton and vector mesons, within holographic QCD, and employing Witten diagrams in the bulk, we compute the diffractive photoproduction amplitude of $J/ψ$ and $Υ$. The holographic amplitude shows elements of the strictures of vector meson dominance (VMD). It is dominated by the exchange of a massive graviton or $2^{++}$ glueball resonances near threshold, and its higher spin-j counterparts that reggeize at higher energies. Both the differential and total cross sections are controlled by the gravitational form factor $A(t)$, and compare well to the recent results reported by the GlueX collaboration near threshold and the world data at large $\sqrt{s}$. The holographic gravitational form factors, including the D-term, which is due to the exchange of massive spin-0 glueballs, are in good agreement with lattice simulations. We use it to extract the holographic pressure and shear forces inside the proton. Finally, using a pertinent integral representation of the holographic gravitational form factor $A(t)$ near threshold, and its Pomeron counterpart way above threshold, we extract the generalized parton distribution (GPD) of gluons inside the proton at different resolutions.

This is the first attempt to observe a sample of head-tail sources at low frequencies. We find weak spectral steepening as we go away from the head along the jet. The Crosspiece has a spectral index of 0.9 (S$_ν \propto ν^{-α}$) and is flatter than the spectral index estimated by Lane et al. (2002). We also see a low surface brightness, diffuse feature at 240 MHz and could be a possible radio relic candidate (see Figure).

Boundary States for Supertubes in Flat Spacetime and Godel Universe
Creators: name: Takayanagi, Hiromitsu
Publisher: name: arXiv
Year: 2003
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We construct boundary states for supertubes in the flat spacetime. The T-dual objects of supertubes are moving spiral D1-branes (D-helices). Since we can obtain these D-helices from the usual D1-branes via null deformation, we can construct the boundary states for these moving D-helices in the covariant formalism. Using these boundary states, we calculate the vacuum amplitude between two supertubes in the closed string channel and read the open string spectrum via the open closed duality. We find there are critical values of the energy for on-shell open strings on the supertubes due to the non-trivial stringy correction. We also consider supertubes in the type IIA Godel universe in order to use them as probes of closed timelike curves. This universe is the T-dual of the maximally supersymmetric type IIB PP-wave background. Since the null deformations of D-branes are also allowed in this PP-wave, we can construct the boundary states for supertubes in the type IIA Godel universe in the same way. We obtain the open string spectrum on the supertube from the vacuum amplitude between supertubes. As a consequence, we find that the tachyonic instability of open strings on the supertube, which is the signal of closed time like curves, disappears due to the stringy correction.

We show that the lineup of the nanotube band structure relative to the metal Fermi-level depends strongly on the metal work function but weakly on the details of the interface. We analyze the length-dependent transport characteristics, which predicts a transition from tunneling to thermally-activated transport with increasing nanotube channel length.

Density Estimators in Particle Hydrodynamics: DTFE versus regular SPH

description: We present the results of a study confronting density maps reconstructed by the Delaunay Tessellation Field Estimator (DTFE) and by regular SPH kernel-based techniques. The comparison between the two methods clearly demonstrates the superior performance of the DTFE with respect to conventional SPH methods, in particular at locations where SPH appears to fail. The DTFE is a fully self-adaptive technique for reconstructing continuous density fields from discrete particle distributions, and is based upon the corresponding Delaunay tessellation. Its principal asset is its complete independence of arbitrary smoothing functions and parameters specifying the properties of these. As a result it manages to faithfully reproduce the anisotropies of the local particle distribution and through its adaptive and local nature proves to be optimally suited for uncovering the full structural richness in the density distribution. Through the improvement in local density estimates, calculations invoking the DTFE will yield a much better representation of physical processes which depend on density. The presented results form an encouraging step towards the application and insertion of the DTFE in astrophysical hydrocodes. We describe an outline for the construction of a particle hydrodynamics code in which the DTFE replaces kernel-based methods. Further discussion addresses the issue and possibilities for a moving grid based hydrocode invoking the DTFE, and Delaunay tessellations, in an attempt to combine the virtues of the Eulerian and Lagrangian approaches.

(Less) naked and (less) afraid: Giving graduate students the clothes and confidence for data success

Publisher: name: Zenodo
Year: 2018

description: The premise of the reality television show Naked and Afraid -- two people released into the wilderness, with no clothing and minimal supplies, tasked with surviving for 21 days -- is an apt analogy for the experience of greenhorn graduate students: dropped into an unfamiliar academic wilderness with little to no survival skills, in a fleeting two-to-five years they are expected to emerge holding a graduate degree. This presentation offers (1) an overview of the services Georgia State University Library's Research Data Services team provides to help social science graduate students with their data needs and (2) an examination of one year of data services consultations with graduate students that further elucidates their pressing data needs and how Georgia State University Library is endeavoring to meet those needs. This close look at one library's experience demonstrates the potential for academic librarians to focus data services efforts on this vulnerable student population, helping them gain the survival skills to feel less naked and less afraid so they may emerge from the graduate-school wilderness clothed and confident in their data-related abilities

description: Probably the most dramatic historical challenge to scientific realism concerns Arnold Sommerfeld's 1916 derivation of the fine structure energy levels of hydrogen. Not only were his predictions good, he derived exactly the same formula that would later drop out of Dirac's 1928 treatment, something not possible using 1925 Schroedinger-Heisenberg quantum mechanics. And yet the most central elements of Sommerfeld's theory were not even approximately true: his derivation leans heavily on a classical approach to elliptical orbits, including the necessary adjustments to these orbits demanded by relativity. Even physicists call Sommerfeld's success a 'miracle', which rather makes a joke of the so-called 'no miracles argument'. However, this can all be turned around. Here I argue that the realist has a story to tell vis-a-vis the discontinuities between the old and the new theory, leading to a realist defence based on sufficient continuity of relevant structure.

description: Here we discuss two many-particle quantum systems, which are obtained by adding some nonhermitian but PT (i.e. combined parity and time reversal) invariant interaction to the Calogero model with and without confining potential. It is shown that the energy eigenvalues are real for both of these quantum systems. For the case of extended Calogero model with confining potential, we obtain discrete bound states satisfying generalised exclusion statistics. On the other hand, the extended Calogero model without confining term gives rise to scattering states with continuous spectrum. The scattering phase shift for this case is determined through the exchange statistics parameter. We find that, unlike the case of usual Calogero model, the exclusion and exchange statistics parameter differ from each other in the presence of PT invariant interaction.

description: With the rise of digital scholarship, the way students interact and produce information has changed, reframing the meaning of storytelling. In the context of a humanities course, two librarians were tasked with finding and teaching tools and resources that would allow students to produce multimedia storytelling projects using spatial and temporal data. While the process was challenging and learning curves were steep, students learned to discover data, create metadata, and combine multimedia information to create a compelling narrative. And they learned to code too! This presentation will discuss the process of introducing humanities students into the world of data. It will explore balancing learning curves with project needs, and opportunities to integrate data into the humanities curriculum. The presenters will also discuss instruction challenges and best practices for librarians and instructors wanting to participate in similar projects.
Bilayer Membrane in Confined Geometry: Interlayer Slide and Steric Repulsion

description: We derived free energy functional of a bilayer lipid membrane from the first principles of elasticity theory. The model explicitly includes position-dependent mutual slide of monolayers and bending deformation. Our free energy functional of liquid-crystalline membrane allows for incompressibility of the membrane and vanishing of the in-plane shear modulus and obeys reflectional and rotational symmetries of the flat bilayer. Interlayer slide at the mid-plane of the membrane results in local difference of surface densities of the monolayers. The slide amplitude directly enters free energy via the strain tensor. For small bending deformations the ratio between bending modulus and area compression coefficient, Kb/KA, is proportional to the square of monolayer thickness, h. Using the functional we performed self-consistent calculation of steric potential acting on bilayer between parallel confining walls separated by distance 2d. We found that temperature-dependent curvature at the minimum of confining potential is enhanced four times for a bilayer with slide as compared with a unit bilayer. We also calculate viscous modes of bilayer membrane between confining walls. Pure bending of the membrane is investigated, which is decoupled from area dilation at small amplitudes. Three sources of viscous dissipation are considered: water and membrane viscosities and interlayer drag. Dispersion has two branches. Confinement between the walls modifies the bending mode with respect to membrane in bulk solution. Simultaneously, inter-layer slipping mode, damped by viscous drag, remains unchanged by confinement.

description: Preferential attachment drives the evolution of many complex networks. Its analytical studies mostly consider the simplest case of a network that grows uniformly in time despite the accelerating growth of many real networks. Motivated by the observation that the average degree growth of nodes is time-invariant in empirical network data, we study the degree dynamics in the relevant class of network models where preferential attachment is combined with heterogeneous node fitness and aging. We propose a novel analytical framework based on the time-invariance of the studied systems and show that it is self-consistent only for two special network growth forms: the uniform and exponential network growth. Conversely, the breaking of such time-invariance explains the winner-takes-all effect in some model settings, revealing the connection between the Bose-Einstein condensation in the Bianconi-Barabási model and similar gelation in superlinear preferential attachment. Aging is necessary to reproduce realistic node degree growth curves and can prevent the winner-takes-all effect under weak conditions. Our results are verified by extensive numerical simulations.

description: To date, various optimization algorithms have been employed to design and improve the performance of nanophotonic structures. Here, we propose to utilize a machine-learning algorithm viz. binary-Additive Reinforcement Learning Algorithm (b-ARLA) coupled with finite-difference time-domain (FDTD) simulations to design ultra-compact and efficient on-chip integrated nanophotonic 50:50 beam splitters (T-junctions). Here we present the design of two T-junction splitters each with a footprint of only 1.2 $μ$m x 1.2 $μ$m. To the best of our knowledge, these designs are amongst the smallest ever reported till date across either simulations or experiments. The simulated net power transmission efficiency for the first T-junction design is ~ 82% and the second design is ~ 80% $at 4λ= 1.55 μ$m. We envision that the design methodology, as reported herein, would be useful in general for designing any efficient integrated-photonic device for optical communications systems.

description: By encouraging and requiring that authors share their data in order to publish articles, scholarly journals have become an important actor in the movement to improve the openness of data and the reproducibility of research. But how many social science journals encourage or mandate that authors share the data supporting their research findings? What influences these journals' decisions to adopt such policies and instructions? And what do those policies and instructions look like? We will discuss the results of our analysis of the instructions and policies of 291 highly ranked journals publishing social science research, where we looked for and measured the quality of journal data policies and instructions across 14 variables, such as when and how authors are asked to share their data, and what role journal ranking and age play in the existence and quality of data policies and instructions

description: Proof of Stake (PoS) blockchains offer promising alternatives to traditional Proof of Work (PoW) systems, providing scalability and energy efficiency. However, blockchains operate in a decentralized manner and the network is composed of diverse users. This openness creates the potential for malicious nodes to disrupt the network in various ways. Therefore, it is crucial to embed a mechanism within the blockchain network to constantly monitor, identify, and eliminate these malicious nodes without involving any central authority. In this paper, we propose MRL-PoS+, a novel consensus algorithm to enhance the security of PoS blockchains by leveraging Multi-agent Reinforcement Learning (MRL) techniques. Our proposed consensus algorithm introduces a penalty-reward scheme for detecting and eliminating malicious nodes. This approach involves the detection of behaviors that can lead to potential attacks in a blockchain network and hence penalizes the malicious nodes, restricting them from performing certain actions. Our developed Proof of Concept demonstrates effectiveness in eliminating malicious nodes for six types of major attacks. Experimental results demonstrate that MRL-PoS+ significantly improves the attack resilience of PoS blockchains compared to the traditional schemes without incurring additional computation overhead.

description: Despite tremendous theoretical efforts to understand subtleties of the many-body localization (MBL) transition, many questions remain open, in particular concerning its critical properties. Here we make the key observation that MBL in one dimension is accompanied by a spin freezing mechanism which causes chain breakings in the thermodynamic limit. Using analytical and numerical approaches, we show that such chain breakings directly probe the typical localization length, and that their scaling properties at the MBL transition agree with the Kosterlitz-Thouless scenario predicted by phenomenological renormalization group approaches.

description: Manual examination of invertebrate species diversity and abundance in Malaise trap samples is a time-consuming and costly task that requires expert knowledge. Automated solutions based on robotics and artificial intelligence can assist experts in evaluating the large number of samples collected, especially when the phenotype of individual species in a sample needs to be assessed and classified. Therefore, we have developed the DiversityScanner, a robotic solution that provides the ability to automatically image, measure, classify, and sort invertebrates (< 3 mm) into 96-well microplates for barcoding. Because it is necessary to document even the smallest details, such as tiny bristles, on a specimen, we have significantly improved the image quality of the detailed images in the DiversityScanner 4k. This is achieved by using an extended focus system and a 12-megapixel camera. By using an electrically focus tunable lens from Optotune, extended focus images can be created from multiple z-stack images with different focus planes. An algorithm then automatically aligns the images, detecting sharp areas in each image, and produces high-resolution extended-focus images. Finally, the object can be classified by a convolutional neural network and the biomass of the insect can be estimated from the image.
Persistent Currents in Helical Structures

description: Recent discovery of mesoscopic electronic structures, in particular the carbon nanotubes, made necessary an investigation of what effect may helical symmetry of the conductor (metal or semiconductor) have on the persistent current oscillations. We investigate persistent currents in helical structures which are non-decaying in time, not requiring a voltage bias, dissipationless stationary flow of electrons in a normal-metallic or semiconducting cylinder or circular wire of mesoscopic dimension. In the presence of magnetic flux along the toroidal structure, helical symmetry couples circular and longitudinal currents to each other. Our calculations suggest that circular persistent currents in these structures have two components with periods $Φ_0$ and $Φ_0/s$ ($s$ is an integer specific to any geometry). However, resultant circular persistent current oscillations have $Φ_0$ period. \pacs{PACS:}PACS:73.23.-b

description: In this work we investigate dynamical systems designed to approach the solution sets of inclusion problems involving the sum of two maximally monotone operators. Our aim is to design methods which guarantee strong convergence of trajectories towards the minimum norm solution of the underlying monotone inclusion problem. To that end, we investigate in detail the asymptotic behavior of dynamical systems perturbed by a Tikhonov regularization where either the maximally monotone operators themselves, or the vector field of the dynamical system is regularized. In both cases we prove strong convergence of the trajectories towards minimum norm solutions to an underlying monotone inclusion problem, and we illustrate numerically qualitative differences between these two complementary regularization strategies. The so-constructed dynamical systems are either of Krasnoselskii-Mann, of forward-backward type or of forward-backward-forward type, and with the help of injected regularization we demonstrate seminal results on the strong convergence of Hilbert space valued evolutions designed to solve monotone inclusion and equilibrium problems.

description: Scholarly research is only as strong as its underlying data and code. Increasing access to scholarly research through open access efforts in the scholarly community aids in dissemination of research; however, limited access to the data behind the research is still a hurdle that publishers and journals are attempting to address. In the social, medical, and life sciences, journal editors are beginning the process of administering data policies. These policies can require authors to submit their data and analysis code alongside their manuscripts -- sometimes to be shared in a repository and sometimes to also be verified before publication. As part of a grant-funded project, the Odum Institute for Research in Social Science and Dryad administered a survey and conducted interviews with journal editors and authors to better understand data policy workflows, identify pain points, and highlight streamlined processes. In this presentation, we will discuss the results of this research which contributed to the development of an implementation model for journals interested in enhancing their current policies or developing new data policies.
