description: Telehealth is needed urgently nationwide, given the COVID-19 pandemic. It isespecially urgent in rural and less populated areas where healthcare access is limited. Currently, because there are no pediatric handwriting assessments validated for telehealth use, the TeleWrite assessment would fill an unmet service need and expand the use of telehealth-based occupational therapy (OT) assessment in pediatric practice. This dissertation explored the preliminary psychometric properties of TeleWrite, a handwriting assessment tool designed to measure the legibility and fluency of handwriting for children in first through third grade administered via telehealth. A series of studies were completed to determine initial interrater reliability, content validity, and clinical utility using classical test theory. The Rasch model of measurement was used to determine the preliminary psychometric properties of TeleWrite using Winsteps® (v. 4.7.0). The quantitative Rasch analysis of TeleWrite included administration of the tool to 148 children from first to third grade. This study tested the initial construct validity (internal validity) and test reliability of TeleWrite using the Rasch model of measurement. The Partial Credit Model (PCM) was used for rating scale analysis because TeleWrite is composed of three distinct scales (handwriting rate, accuracy, and fluency) that differs per task (near point or far point) and per grade level. The Rasch analysis showed a generally good fit with the Rasch unidimensional model, indicating strong construct and internal validity and moderate ability to separate abilities of students reliably in terms of handwriting skills. However, following the Rasch model, a larger sample is necessary to obtain improved calibration, reliability, and validity measures. This study and supported by the literature described the need for a new handwriting evaluation tool validated for telehealth use. The findings of the current research contribute to the literature and OT practice as the first handwriting assessment specifically designed and validated for telehealth use that assesses all pertinent variables of handwriting associated with handwriting difficulties.

description: In Yang-Mills theories, variational calculations of the Rayleigh-Ritz type face the problem that on the one hand, calculability puts severe constraints on the space of test wave functionals; on the other hand, the test wave functionals have to be gauge invariant. The conflict between the two requirements can be resolved by introducing a projector. In this paper we present an approach to approximating the projector in a way known and successfully employed in nuclear physics: the Kamlah expansion. We discuss it both for electrodynamics and for Yang-Mills theories to leading order in a perturbative expansion, and demonstrate that the results are compatible with what one would expect from perturbation theory.

description: The recently published GWTC-1 - a journal article summarizing the search for gravitational waves (GWs) from coalescing compact binaries in data produced by the LIGO-Virgo network of ground-based detectors during their first and second observing runs - quoted estimates for the rates of binary neutron star, neutron star black hole binary, and binary black hole mergers, as well as assigned probabilities of astrophysical origin for various significant and marginal GW candidate events. In this paper, we delineate the formalism used to compute these rates and probabilities, which assumes that triggers above a low ranking statistic threshold, whether of terrestrial or astrophysical origin, occur as independent Poisson processes. In particular, we include an arbitrary number of astrophysical categories by redistributing, via mass-based template weighting, the foreground probabilities of candidate events, across source classes. We evaluate this formalism on synthetic GW data, and demonstrate that this method works well for the kind of GW signals observed during the first and second observing runs.

description: Quasiparticle interference (QPI) is a powerful technique within Scanning Tunneling Microscopy (STM) that is used to probe the electronic bandstructure of materials. This thesis presents two examples using QPI to measure the bandstructure in materials with exotic electronic states that can be tuned via outside parameters (temperature and strain). In Part I of the thesis, we discuss the temperature dependence of Fermi Arcs in 1T’-MoTe2, and then in Part II, the strain dependent nematic state in NaFeAs. The recent discovery of Weyl semimetals has introduced a new family of materials with topologically protected electronic properties and potential applications due to their anomalous transport effects. Even more useful is a Weyl semimetal that can be turned “on” and “off,” switching between a topological and trivial state. One possible material is MoTe2, which undergoes a phase transition at 240K. This thesis consists of experiments using Scanning Tunneling Microscopy (STM) and Spectroscopy (STS) at different temperatures to visualize changes in the electronic bandstructure of MoTe2 across the topological phase transition. We show that a signature of topologically protected Fermi Arcs is present at low temperatures but disappears at room temperature, in the trivial phase. We include an in-depth discussion of how to account for thermal effects when comparing these two types of measurements. In Part II, we discuss strain induced nematicity in NaFeAs, an iron pnictide. Nematic fluctuations and spin correlations play an important role in the phase diagram of the iron pnictides, a family of unconventional superconductors. Illuminating the mechanism behind this symmetry breaking is key to understanding the superconducting state. Previous work has shown that nematicity in the iron pnictides responds strongly to applied strain [1, 2]. In this thesis, I present results from a new experimental technique, elasto-scanning tunneling microscopy (E-STM), which combines in situ strain and atomic resolution STM/STS. For the first time, we are able to observe the effects of strain on nematicity at the local level. We perform E-STM measurements in both the spin density wave phase and the tetragonal phase of NaFeAs and measure a distinct response in each. We successfully use strain to manipulate domain boundaries in the spin density wave state and we find the intensity of nematic fluctuations is coupled to strain in NaFeAs in the tetragonal phase.

description: We reviewed published research on natural hazards and community disaster resilience to identify how relationships between people and their experiences of disaster interact to shape possibilities for positive transformative change. Research commonly analyzes processes within and across individual and collective or structural spheres of a social system, but rarely investigates interactions across all three. We present a framework focused on ‘spheres of influence’ to address this. The Framework shows how positive relationships that prioritize restoring shared, meaningful and purposeful identities can lead to expansive and incremental capacity for transformative outcomes for sustainability: a process we liken to the butterfly effect.

description: Die Natur- und Technikwissenschaften prägen grundlegend die Lebenswelt der Menschen. Dabei bringen Technologien permanent neue Produkte und Werkzeuge hervor, die Arbeit und Kultur ebenso wie das Freizeitverhalten beeinflussen und Rückwirkungen auf Natur und Gesellschaft haben. Diese Innovationen entstehen zunehmend durch gemeinsame Entwicklungsarbeit unterschiedlicher Disziplinen (z.B. Medizintechnik). Interdisziplinarität wird somit zu einem Forschungs- und Arbeitsprinzip, ohne die hybride Problemstellungen der Gegenwart und Zukunft nicht gelöst werden können. Ein solch komplexes Zusammenspiel in der Lösung von Problemen erfordert mehr denn je eine ausreichende natur- und technikwissenschaftliche Bildung. In diesen Zusammenhängen muss es daher Ziel sein, Bildung grundzulegen, die zum interdisziplinären Denken und zum Nachvollziehen oder Lösen von Problemen befähigt. In dem Artikel wird zunächst die aktuelle Situation interdisziplinärer natur- und technikwissenschaftlicher Bi ldung in der Eingangstufe des Gymnasium analysiert. Daran anschließend wird ein didaktisches Modell entwickelt, das die Bereiche Natur und Technik interdisziplinär verknüpft. Dieses Modell baisiert auf Grundannahmen der konstruktivistischen Erkenntnistheorie und des Problemlösens, aus denen didaktische Grundprinzipien für ein interdisziplinäres didaktisches Modell abgeleitet werden.

description: We present ALMA maps of the starless molecular cloud core Ophiuchus/H-MM1 in the lines of deuterated ammonia (ortho-NH2D), methanol (CH3OH), and sulphur monoxide (SO). The dense core is seen in NH2D emission, whereas the CH3OH and SO distributions form a halo surrounding the core. Because methanol is formed on grain surfaces, its emission highlights regions where desorption from grains is particularly efficient. Methanol and sulphur monoxide are most abundant in a narrow zone that follows the eastern side of the core. This side is sheltered from the stronger external radiation field coming from the west. We show that photodissociation on the illuminated side can give rise to an asymmetric methanol distribution, but that the stark contrast observed in H-MM1 is hard to explain without assuming enhanced desorption on the shaded side. The region of the brightest emission has a wavy structure that rolls up at one end. This is the signature of Kelvin-Helmholtz instability occurring in sheared flows. We suggest that in this zone, methanol and sulphur are released as a result of grain-grain collisions induced by shear vorticity.

description: We present results for the large-$p_T$ inclusive $π^0$ production in p-p and A-A collisions at RHIC and LHC energies. We include the full next-to-leading order radiative corrections, $O(α_s^3)$, and nuclear effects such as parton energy loss and nuclear shadowing. We find the next-to-leading order corrections and the parton energy loss effect to be large and $p_T$ dependent, while the nuclear shadowing effects are small ($< 10%$). We calculate the ratio of prompt photons to neutral pions produced in heavy ion collisions and show that at RHIC energies this ratio increases with $p_T$ approaching one at $p_T \sim 8$ GeV, due to the large suppression of $π^0$ production. We show that at the LHC, this ratio has a steep $p_T$ dependence and approaches 25% effect at $p_T \sim 40$ GeV. We discuss theoretical uncertainties inherent in our calculation, such as choice of the renormalization, factorization and fragmentation scales and the K-factors which signify the size of higher-order corrections.

description: Telling technology explores how modernist literature makes sense of technological change by means of narration. The dissertation consists of three case studies focusing on narrative texts by Robert Walser, Paul Scheerbart, and Joseph Roth. These authors write at a time when a crisis of ‘progress,’ understood as a basic concept of history, coincides with a crisis of narration in the form of anthropocentric, action-based storytelling. Through close readings of their technographic writing, the case studies investigate how the three authors develop alternative forms of narration so as to tackle the questions posed by the sweeping technological change in their day. Along with a deeper understanding of the individual literary texts, the dissertation establishes a theoretical framework to discuss questions of modern technology and agency through the lens of narrative theory.

description: We introduce a supercooled liquid model and obtain parameter-free quantitative predictions that are in excellent agreement with numerical simulations, notably in the hard low-temperature region characterized by strong deviations from Mode-Coupling-Theory behavior. The model is the Fredrickson-Andersen Kinetically-Constrained-Model on the three-dimensional $M$-layer lattice. The agreement has implications beyond the specific model considered because the theory is potentially valid for many more systems, including realistic models and actual supercooled liquids.

Experimental Evaluation of Acid Mine Drainage Potential for Cemented Paste Backfill

Publisher: name: The University of British Columbia
Year: 2023

description: Safe environmental management of sulfide-bearing tailings material is a significant concern for mining operations. Iron sulfides (mostly pyrite and pyrrhotite) are common in sulfide-bearing mining waste materials. Surface disposal of these waste materials will lead to oxidation in the presence of air and water, eventually generating acid mine drainage (AMD). The utilization of tailings using the cemented paste backfilling method eliminates the necessity of storing most of the tailings on the surface, reducing the environmental footprint. In this study, static and kinetic testing were conducted on the tailings and cemented past backfill mixture to evaluate the potential of acid mine drainage. From the performed static test on the tailings sample through the Acid-Base Accounting (ABA) method, the results of the net neutralization potential and the ratio of neutralization potential to acid potential show that the tailings material will be acid-generating. An X-Ray diffraction (XRD) test was conducted on the tailings sample for composition analysis. Kinetic tests measure the dynamic performance or reactivity of excavated and exposed materials over time. The column leach testing setup in the laboratory is designed to observe the weekly wet-dry and leaching cycles of cemented paste backfill (CPB) mixtures. The 6-inch diameter by 12-inch long cylindrical PVC columns are filled with CPB materials. The mixture contains tailings, Portland cement, and water. The test set-up was designed following a components matrix, in which six columns contained CPB mixtures and two columns contained tailings only. The columns are wetted by applying deionized water from the surface, and the leachate water is collected for measurement in a container located at the base. To simulate the drying environment of natural weather, heat lamps at the top are used to ensure sample drying between test solution applications. Typically, the test solution was applied weekly and the leachates were collected every week. For over fifty weeks, the pH and electrical conductivity were measured and analysed weekly on the percolated water for potential AMD evaluation. In the control column, it was observed that the pH value transitioned towards acidic within the first few weeks of measurements. During the initial week of measurements on cemented columns, the compacted samples showed higher pH values than the uncompacted samples. In the first few weeks, the cemented columns showed pH values around 10 to 12. Then in later weeks, the pH values gradually started to stabilize around 6 to 8.

description: We study the moduli space ${\cal M}$ of N=(4,4) superconformal field theories with central charge c=6. After a slight emendation of its global description we find the locations of various known models in the component of ${\cal M}$ associated to K3 surfaces. Among them are the Z_2 and Z_4 orbifold theories obtained from the torus component of ${\cal M}$. Here, SO(4,4) triality is found to play a dominant role. We obtain the B-field values in direction of the exceptional divisors which arise from orbifolding. We prove T-duality for the Z_2 orbifolds and use it to derive the form of ${\cal M}$ purely within conformal field theory. For the Gepner model (2)^4 and some of its orbifolds we find the locations in ${\cal M}$ and prove isomorphisms to nonlinear sigma models. In particular we prove that the Gepner model (2)^4 has a geometric interpretation with Fermat quartic target space.

description: The complex interplay between climate change, demographics and socioeconomic conditions is transforming the global environmental health landscape. In the aftermath of recent heat waves around the world, especially the 2003 heat wave in Europe, heat is being recognized as an emerging public health issue worldwide, particularly in urban areas.
This work explores the historical and future heat-related mortality in New York City, from the beginning of the 20th until the end of the 21st century. New York City is among the largest cities in the world and has been a thriving metropolis over the entire period covered by this study. The unique makeup of the city makes it particularly suitable for studying the impacts of heat over an extended period of time. The presented work encompasses multiple domains of knowledge and illustrates the necessity for applying highly interdisciplinary approaches in addressing the emerging challenges of our time.
The background chapter provides an overview of methodological approaches and findings from previous studies with direct relevance to the specific aims of this work. Chapter I is focused on characterizing the impacts of heat on daily mortality since 1900. Here, heat effects are presented in a historical context and changes over time are analyzed and discussed. Chapter II provides a comparative assessment of recent historical and heat impacts until 2100 in New York City, Boston and Philadelphia. This analysis illustrates the differences and similarities between heat impacts in New York City and the other two major urban areas in the U.S. Northeast. Chapter III provides a more comprehensive assessment of future heat-related mortality in New York City under a number of adaptation, climate change and demographic scenarios. The concluding chapter presents a summary of findings and recommendations for future research.

description: Quantum entanglement plays a pivotal role in many communication protocols, like secret sharing and quantum cryptography. We consider a scenario where more than two parties are involved in a protocol and share a multipartite entangled state. In particular, we considered the protocol of Controlled Quantum Key Distribution (CoQKD), introduced in the Ref. Chin. Phys. Lett. 20, 183-185 (2003), where, two parties, Alice and Bob establish a key with the cooperation of other parties. Other parties control/supervise whether Alice and Bob can establish the key, its security and key rate. We discuss the case of three parties in detail and find suitable resource states. We discuss the controlling power of the third party, Charlie. We also examine the usefulness of the new resource states for generating conference key and for cooperative teleportation. We find that recently introduced Bell inequalities can be useful to establish the security of the conference key. We also generalize the scenario to more than three parties.

description: This dissertation presents a series of five papers to better understand how to measure discounting, how and why discounting of losses differs from discounting of gains, and how to apply research on discounting to public policy. Paper 1 compares two common methods of measuring discounting - titration and matching - with a dynamic "multiple staircase" method adapted from psychophysics. Paper 2 examines the robustness of the sign effect across financial, environmental, and health domains. Paper 3 explores the interaction of sign and magnitude, and offers an explanation for why losses reverse or eliminate the magnitude effect. Paper 4 investigates an explanation for the sign effect: that dread looms larger than pleasurable anticipation, and Paper 5 offers an integrative approach to intertemporal choice, with recommendations for environmental policy. Taken together, these investigations suggest that discounting of losses is both quantitatively and qualitatively different from discounting of gains. Across domains and methods losses are discounted much less than gains and losses eliminate (or reverse) the magnitude effect. These behavioral differences occur because "dread" of losses is more pronounced than pleasurable anticipation of gains. In other words, people dislike having losses hanging over their heads more than they enjoy looking forward to positive events. For this reason, while people almost universally want to have gains immediately (due to impatience and other reasons), people are divided about losses - sometimes preferring to realize them immediately, and sometimes preferring to postpone them. Theories and policies involving intertemporal choice must distinguish between losses and gains if they hope to accurately describe and predict people's choices.

description: In analysis of binary outcomes, the receiver operator characteristic (ROC) curve is heavily used to show the performance of a model or algorithm. The ROC curve is informative about the performance over a series of thresholds and can be summarized by the area under the curve (AUC), a single number. When a predictor is categorical, the ROC curve has one less than number of categories as potential thresholds; when the predictor is binary there is only one threshold. As the AUC may be used in decision-making processes on determining the best model, it important to discuss how it agrees with the intuition from the ROC curve. We discuss how the interpolation of the curve between thresholds with binary predictors can largely change the AUC. Overall, we show using a linear interpolation from the ROC curve with binary predictors corresponds to the estimated AUC, which is most commonly done in software, which we believe can lead to misleading results. We compare R, Python, Stata, and SAS software implementations. We recommend using reporting the interpolation used and discuss the merit of using the step function interpolator, also referred to as the "pessimistic" approach by Fawcett (2006).

description: Finding a good regularization parameter for Tikhonov regularization problems is a though yet often asked question. One approach is to use leave-one-out cross-validation scores to indicate the goodness of fit. This utilizes only the noisy function values but, on the downside, comes with a high computational cost. In this paper we present a general approach to shift the main computations from the function in question to the node distribution and, making use of FFT and FFT-like algorithms, even reduce this cost tremendously to the cost of the Tikhonov regularization problem itself. We apply this technique in different settings on the torus, the unit interval, and the two-dimensional sphere. Given that the sampling points satisfy a quadrature rule our algorithm computes the cross-validations scores in floating-point precision. In the cases of arbitrarily scattered nodes we propose an approximating algorithm with the same complexity. Numerical experiments indicate the applicability of our algorithms.
Multiple imaging by gravitational waves

description: Gravitational waves act like lenses for the light propagating through them. This phenomenon is described using the vector formalism employed for ordinary gravitational lenses, which was proved to be applicable also to a non-stationary spacetime, with the appropriate modifications. In order to have multiple imaging, an approximate condition analogous to that for ordinary gravitational lenses must be satisfied. Certain astrophysical sources of gravitational waves satisfy this condition, while the gravitational wave background, on average, does not. Multiple imaging by gravitational waves is, in principle, possible, but the probability of observing such a phenomenon is extremely low.

description: Caenorhabditis elegans is a promising organism for trying to understand how nervous systems generate real-time behavior. Its low neuron count suggests that we may be able to observe all of the constituents of the computation of sophisticated sensorimotor behavior. However, its appropriateness as a system for quantitative dynamical study has yet to be established. We show that C. elegans chemosensory neurons can operate in a highly deterministic and low-noise mode, and they act as reliable linear filters of their input. We then use dynamical systems analysis in combination with classical genetic perturbation to uncover cellular and circuit mechanisms of temporal processing. This work should firmly establish C. elegans as a viable platform for applying quantitative dynamical systems methods to understanding how a nervous system processes sensory information, integrates it with an evolving internal state, and produces goal-directed, coordinated behavior.

description: One of the critical aspects of the safety management of tailings dams is the definition and implementation of systematic and integrated operational processes for the observation of their structural and geotechnical behaviour, do as to act preventively in risk assessment and to be able to implement mitigation measures when and if they prove necessary. In this work we present the tools and the methodologies used in the deterministic and statistical analysis of monitoring data from piezometers and water level indicators to define the criteria for the activation of Trigger Action Response Plans (TARPs) and to assess their level, which are essential for the safe operation of tailings dams. The TARPs define, at different levels, the actions to be taken in case of observed deviation from the normal safety operation conditions of the structures, and thus mitigate the associated risks and restore normal operating conditions. The readings of the different types of instruments installed in a tailings dam (piezometers and water level indicators) are compared with reference values defined in accordance with deterministic analyses and statistical analyses of the historical data. This helps in the evaluation of the global risk level of the structure at a specific point in time. The deterministic analyses, based on the stability analysis of the structure, allow us to determine the Control Levels of each sensor and to establish their level of risk. In the implemented methodology, the criterion for the activation of the TARPs was based on a weighted average of the level of risk of each sensor, taking into consideration its location and its relative importance in the global behaviour of the dam. The statistical analysis evaluates over time the historical readings of each sensor and identifies statistically abnormal behaviours, establishing zones of coherent and incoherent readings. In the methodology implemented, different classes of Tendency Alerts were defined.

description: Vorab sei erinnert: Vernunft wird immer nur von dem geweckt, was an ihm selbst vernünftig ist. In der Sprache der Mittleren Epoche: ein intellectus hat eine ratio zur Vorgabe, der concipierende intellectus das Rationale einer sapientia. Die christliche erscheint in dem Christus, der sie wissen läßt, "lehrt" als "Sohn" des göttlichen Wissens; er "ist", indem er die Wahrheit "tut"; daher: non est aliud filius, aliud doctrina eius, sed ipsa doctrina filius est (Augustinus, de trinitate II c.2, § 4,12). Nur als solcher ruft er den ihm entsprechenden intellectus hervor - in einer "Erneuerung der Vernunft" (Paulus, Römerbrief 12,2). Sie ist die des "neuen" Menschen, der sich der "Lehre" gemäß von sich unterschieden hat. Das Concipieren der Lehre in einer ihr angemessenen philo-sophischen Logik erfordert aber eine Unterscheidung der Vernunft von sich selbst, von ihrer natürlichen wie auch weltlichen Prägung (s. Einführung in die Vernünftigkeit des Neuen Testaments, BWG Jahrbuch 1988).

description: Internal erosion is a common cause of dam failures and is a key consideration when designing tailing storage facilities (TSFs) and water retaining structures. Initiation of internal erosion is a complex phenomenon and can be difficult to characterize. Filters are often employed to prevent particle migration and can greatly reduce the risk of internal erosion. However, defects can occur in filter layers due to differential settlement, improper construction practices, seismic shaking, or other unforeseen factors. When a filter defect is present, initiation of internal erosion of base materials becomes more likely as concentrated seepage flow paths will force particle migration through the open defect. The ability of a soil medium to arch can be advantageous as arching can resist the effect of seepage drag forces by redistributing the stresses to the zones adjacent to the defect, providing resistance to initiation of internal erosion. However, if superior tractive seepage forces exist, arching can be overcome, the soil will lose its self-supporting ability, and internal erosion will be initiated. To explore this limiting stability condition, a series of finite-element stress-deformation simulations were performed. Varying material shear strengths, defect aperture sizes, and seepage gradients and their corresponding effects on the triggering of internal erosion were evaluated. This paper summarizes the methods and results of these analyses, including applicability to tailing dam design, with the aim of providing a screening tool for practitioners to use to quickly evaluate internal erosion resistance in the presence of a filter defect.

description: We present a nucleon resonance analysis by simultaneously considering all pion- and photon-induced experimental data on the final states gamma N, pi N, 2 pi N, eta N, K Lambda, K Sigma, and omega N for energies from the nucleon mass up to sqrt(s) = 2 GeV. In this analysis we find strong evidence for the resonances P_{31}(1750), P_{13}(1900), P_{33}(1920), and D_{13}(1950). The omega N production mechanism is dominated by large P_{11}(1710) and P_{13}(1900) contributions. In this first part, we present the results of the pion-induced reactions and the extracted resonance and background properties with emphasis on the difference between global and purely hadronic fits.
