Resurrecting the N = 20 shell closure and upgrades to the TITAN measurement Penning trap
Creators: name: Lykiardopoulou, Eleni Marina
Publisher: name: University of British Columbia
Year: 2023

description: Experimental investigations of nuclear structure provide a probe to study the strong nuclear force, many properties of which still remain unknown. One powerful way to experimentally investigate nuclear structure is through the mass of the atomic nucleus, as it reveals the binding energy of the nucleus. In this work, mass measurements of Mg and Na isotopes are carried out and the results indicate, for the first time, a gradual re-emergence of magicity or closed shell behavior for Z ≤ 11 nuclei at the N = 20 island of inversion. The results also discover a previously unknown low-lying isomer, hence a long-lived excited state in ³²Na. In addition, complementary work at higher mass numbers which combines mass measurements and decay energies allows us to trace the two-proton dripline between iridium and lead, thus determining the limits of existence for elements with proton numbers Z = 77−82 on the proton-rich side of the Segrè chart. Comparisons with some theoretical calculations for this work show agreement while others, such as ab initio theory calculations, are currently unable to reproduce effects of the N = 20 island of inversion, and will require further developments. Yet the mass measurements serve as important benchmarks. Beyond studies of nuclear structure via direct mass measurements, this thesis describes the technical developments and improvements to the Measurement Penning Trap (MPET). The Penning trap, an experimental apparatus that uses electric and magnetic fields to determine the atomic mass through the ion’s cyclotron frequency, has been upgraded to operate at cryogenic temperatures with the goal to reach storage times on the order of seconds for highly-charged Ions. The aim for this upgrade is an improvement of the achievable precision by an order of magnitude. In addition, simulations and further technical upgrades towards the implementation of the Phase-Imaging Ion-Cyclotron measurement technique are carried out. With its new capabilities, the TITAN MPET is now able to perform mass measurements of short-lived radioactive isotopes in singly and highly charged states with an unprecedented precision.

description: The total infrared (TIR) luminosity from galaxies can be used to examine both star formation and dust physics. We provide here new relations to estimate the TIR luminosity from various Spitzer bands, in particular from the 8 micron and 24 micron bands. To do so, we use 45" subregions within a subsample of nearby face-on spiral galaxies from the Spitzer Infrared Nearby Galaxies Survey (SINGS) that have known oxygen abundances as well as integrated galaxy data from the SINGS, the Local Volume Legacy Survey (LVL) and Engelbracht et al. (2008) samples. Taking into account the oxygen abundances of the subregions, the star formation rate intensity, and the relative emission of the polycyclic aromatic hydrocarbons at 8 micron, the warm dust at 24 micron and the cold dust at 70 micron and 160 micron we derive new relations to estimate the TIR luminosity from just one or two of the Spitzer bands. We also show that the metallicity and the star formation intensity must be taken into account when estimating the TIR luminosity from two wave bands, especially when data longward of 24 micron are not available.

description: The accuracy and reliability of vehicle localization on roads are crucial for applications such as self-driving cars, toll systems, and digital tachographs. To achieve accurate positioning, vehicles typically use global navigation satellite system (GNSS) receivers to validate their absolute positions. However, GNSS-based positioning can be compromised by interference signals, necessitating the identification, classification, determination of purpose, and localization of such interference to mitigate or eliminate it. Recent approaches based on machine learning (ML) have shown superior performance in monitoring interference. However, their feasibility in real-world applications and environments has yet to be assessed. Effective implementation of ML techniques requires training datasets that incorporate realistic interference signals, including real-world noise and potential multipath effects that may occur between transmitter, receiver, and satellite in the operational area. Additionally, these datasets require reference labels. Creating such datasets is often challenging due to legal restrictions, as causing interference to GNSS sources is strictly prohibited. Consequently, the performance of ML-based methods in practical applications remains unclear. To address this gap, we describe a series of large-scale measurement campaigns conducted in real-world settings at two highway locations in Germany and the Seetal Alps in Austria, and in large-scale controlled indoor environments. We evaluate the latest supervised ML-based methods to report on their performance in real-world settings and present the applicability of pseudo-labeling for unsupervised learning. We demonstrate the challenges of combining datasets due to data discrepancies and evaluate outlier detection, domain adaptation, and data augmentation techniques to present the models' capabilities to adapt to changes in the datasets.

description: We define for any 4-tetrahedron (4-simplex) the simplest finite closed piecewise flat manifold consisting of this 4-tetrahedron and of the one else 4-tetrahedron identical up to reflection to the present one (call it bisimplex built on the given 4-simplex, or two-sided 4-simplex). We consider arbitrary piecewise flat manifold. Gravity action for it can be expressed in terms of sum of the actions for the bisimplices built on the 4-simplices constituting this manifold. We use representation of each bisimplex action in terms of rotation matrices (connections) and area tensors. This gives some representation of any piecewise flat gravity action in terms of connections. The action is a sum of terms each depending on the connection variables referring to a single 4-tetrahedron. Application of this representation to the path integral formalism is considered. Integrations over connections in the path integral reduce to independent integrations over finite sets of connections on separate 4-simplices. One of the consequences is exponential suppression of the result at large areas or lengths (compared to Plank scale). It is important for the consistency of the simplicial description of spacetime.

description: The physical and human capital stock of a country determines its economic development and functioning. Despite the Federal Government of Nigeria's initiatives and policies aimed at ensuring the country's long-term viability. Citizens' nutritional status is still a widespread issue that undermines productivity. For a period of 41 years, the impact of government expenditures and food importation on overweight and stunting was studied using dynamic ordinary least squares and simulation (1980-2020). Stunting and overweight are reduced as a result of food production and importation, according to the findings. Stunting and overweight will be reduced by 2.12 percent and 1.22 percent, respectively, if public spending increases and food imports are reduced by 30%. To complement public initiatives, the best alternative policy for improving Nigeria's nutrition status should focus on increasing government agriculture and health spending, as well as increasing food imports with a lower comparative advantage.
Exploring brain activation patterns during a buttoning task in healthy young adults and individuals with traumatic brain injury : a functional near infrared spectroscopy investigation
Creators: name: Benam, Niloufar
Publisher: name: University of British Columbia
Year: 2023

description: Background: Activities of daily living (ADLs), such as dressing, and toileting, are an important part of everyday life. The ability to complete ADLs can promote feelings of well-being and is important for having a sense of independence. Dressing is an ADL that is completed on a daily basis. However, there is currently limited knowledge on brain activity during dressing tasks. Previous studies explored brain activity during dressing using fMRI. However, there are limitations with fMRI in that participants have to retain a supine position during neuroimaging which is not a natural position when a person is dressing. A promising technology, functional near-infra red spectroscopy (fNIRS), can investigate brain activity during a dressing task of buttoning in a more natural state. Purpose: The studies involved in this thesis aim to use fNIRS to: (1) investigate brain activity during buttoning in healthy adults; and (2) explore brain activation patterns in individuals who have sustained a moderate to severe traumatic brain injury (TBI) while completing a buttoning task. Methods: Participants in both studies completed a task of buttoning in three 20 second repetitions with 15 seconds rest in between each activity time block. Brain activation patterns were recorded using fNIRS over the prefrontal cortex, premotor cortex, supplementary motor area, sensorimotor cortex, and posterior parietal cortex. Results: There were twenty healthy participants recruited from the community for study 1. Study 2 involved two participants with severe TBI. Significantly higher activation in the prefrontal cortex, premotor cortex, supplementary motor area, and sensorimotor cortex was observed for healthy control participants during the activity block when compared to the resting state. In study 2, brain activity in both TBI participants showed decreased activity within the premotor cortex and supplementary motor area and increased brain activity within the posterior parietal cortex during task performance compared to rest condition. Conclusions: Understanding brain activity during performance of activities of daily living in healthy adults is a critical first-step for investigating brain activation in different clinical populations such as TBI.
Microscopic models of nuclear reactions near the Coulomb barrier

Publisher: name: The Australian National University

description: A complete understanding of dynamic behaviour of a strongly interacting quantum many-body system like the atomic nucleus remains elusive. Nuclear reactions at energies near the Coulomb barrier are uniquely sensitive to quantum effects. In particular, collective tunnelling and nuclear shell effects are important to the dynamics of these reactions. Mean-field techniques allow for effective microscopic models of the nucleus but there are still remaining challenges. How should a mean-field based approach be generalised to describe collective tunnelling of strongly interacting systems? Can mean-field simulations replicate the shell effects seen in formation of fission fragments, and would they depend on the history of the system? One way to address this question is to compare mean-field simulations of quasifission (damped heavy-ion collisions with significant mass equilibration) and fission of a compound nucleus. An imaginary time extension to mean-field theory was tested, which reproduced collective tunnelling behaviours and their probabilities. Fission was studied through the production of potential energy surfaces via a constrained Hartree-Fock calculation. Quasifission of heavy and superheavy systems was studied via time-dependent Hartree-Fock calculations. The imaginary time theory was shown to have potential but encounters some difficult numerical challenges. The potential energy surfaces revealed features identified with shell effects driving fission in both actinide thorium and superheavy oganesson nuclides. Mapping the quasifission trajectories onto the calculated potential energy surfaces provided useful information about how the shell effects in fission relate to quasifission. An approach to analyse quasifission dynamics using the topology of the underlying compound nuclear potential energy surface was proposed. The strength of mean-field models for testing and understanding nuclear near-barrier dynamics was confirmed. The correspondence between microscopic and collective degrees of freedom in different reactions is of importance, and resulting models can be tested with experiment.
A Reinvestigation of Moving Punctured Black Holes with a New Code

description: We report on our code, in which the moving puncture method is applied and an adaptive/fixed mesh refinement is implemented, and on its preliminary performance on black hole simulations. Based on the BSSN formulation, up-to-date gauge conditions and the modifications of the formulation are also implemented and tested. In this work we present our primary results about the simulation of a single static black hole, of a moving single black hole, and of the head-on collision of a binary black hole system. For the static punctured black hole simulations, different modifications of the BSSN formulation are applied. It is demonstrated that both the currently used sets of modifications lead to a stable evolution. For cases of a moving punctured black hole with or without spin, we search for viable gauge conditions and study the effect of spin on the black hole evolution. Our results confirm previous results obtained by other research groups. In addition, we find a new gauge condition, which has not yet been adopted by any other researchers, which can also give stable and accurate black hole evolution calculations. We examine the performance of the code for the head-on collision of a binary black hole system, and the agreement of the gravitational waveform it produces with that obtained in other works. In order to understand qualitatively the influence of matter on the binary black hole collisions, we also investigate the same head-on collision scenarios but perturbed by a scalar field. The numerical simulations performed with this code not only give stable and accurate results that are consistent with the works by other numerical relativity groups, but also lead to the discovery of a new viable gauge condition, as well as clarify some ambiguities in the modification of the BSSN formulation.

While typical gauge mediation predictions of either a neutralino or stau next-to-lightest supersymmetric particle (NLSP) are easily reproducible with the GGM parameters, chargino and sneutrino NLSPs are generic for many reasonable choices of GGM parameters.

description: Benzophenone (BP) is an emerging contaminant that is widely distributed in soil, groundwater, sediment and surface water. In this study, the degradation kinetics, mechanisms, and influence of anions on thermally activated persulphate (TAP) oxidation of BP were systematically investigated. BP degradation was promoted by elevated temperature. The BP degradation data fitted well to the Arrhenius equation with calculated activation energy of 122.8 kJ/mol. BP degradation was also promoted by alkaline pH and high persulphate concentrations. Radical scavenging experiments suggested that both SO4•− and HO• were involved in BP oxidation. Ultra-high-performance liquid chromatography coupled to Orbitrap mass spectrometry (UHPLC-Orbitrap-MS) identified six degradation intermediates. Based on these results, two possible reaction pathways were proposed. Water matrix anions had complex impacts on BP degradation by TAP. Cl− had dual effects on the reaction: low concentration promoted it while high concentration inhibited it. Br− strongly suppressed the reaction. SO42− and NO3− did not affect the reaction. Overall, this study shows that thermally activated persulphate can effectively remove BP and water matrix anions greatly influence the reaction.

description: Defects in single-walled carbon nanotubes (SWCNTs) degrade their mechanical,electrical, and thermal properties, limiting their potential applications. To realize the diverse applications of SWCNTs, it is essential to enhance their crystallinity through effective defect healing. However, traditional thermal treatments typically require temperatures above 1800°C, which can alter the nanotube structure. Previously, defect healing of SWCNTs was achieved at a relatively low temperature of 1100°C, using C$_{2}$H$_{2}$ assistance, but the efficiency was limited. In this study, we developed a C$_{2}$H$_{2}$-assisted multiple-cycle process at an even lower temperature of 1000°C combined with air exposure, achieving highly efficient defect healing while preserving the nanotube structure. The combination of multiple-cycle treatment and air exposure between cycles was found to promote defect activation, suppress the formation of amorphous carbon, and enhance the effectiveness of defect healing. Additionally, we successfully healed commercially available bulk-scale SWCNTs (super-growth SWCNTs), noting that their healing behavior differed from lab-grown SWCNTs with smaller diameters synthesized from nanodiamond. The efficient and structure-preserved healing process developed in this study broadens the potential applications of high-quality SWCNTs, including flexible electronics, high-performance composites, and energy storage devices.

description: Critical opalescence is a characteristic experimental signature of a second order phase transition in solid state physics. A new, experimentally accessible measure of opacity and of attenuation length in heavy ion reactions is suggested, as a combination of HBT radii and nuclear modification factors. This opacity is maximal when $\sqrt{s_{NN}}$, the system size and centrality correspond to the critical point of QCD. To characterize the phase transition at this critical point, the critical exponent of the correlation function can be determined by measuring the Lévy index of stability of the Bose-Einstein or HBT correlations. The exponent of the correlation length can be determined from fits to the multiplicity distribution in various pseudorapidity intervals, also as a function of colliding energy, system size, centrality and (chemical) freeze-out temperature. These two critical exponents determine the remaining four critical exponents and the universality class of this second order phase transition. As a control experiment, the determination of the critical exponent of the specific heat capacity is proposed, from event-by-event fluctuation measurements. To measure opacity precisely, well calibrated high transverse momentum probes are needed, such as given by the excitation function of $γ$ + jet correlation functions.

Mind the collaborative gap : learning through the construction of boundaries, boundary objects, and assemblages
Creators: name: Walsh, Monique
Publisher: name: University of British Columbia
Year: 2023

description: Recent policy changes in primary care are asking healthcare professionals to work collaboratively. Although it may be counterintuitive, such collaboration can be understood according to the practice of constructing boundaries. This dissertation is formulated as three distinct interdisciplinary papers that apply a performative ontological lens to exploring how the practice of collaboration changes in primary care workplaces. The first paper contributes to an ongoing dialogue within the field of knowledge management that traces the ways that boundaries and boundary objects are enacted. This paper argues that the construction of these boundaries and boundary objects make the process of collaboration observable and therefore changeable. Comparatively, the second paper draws from the sociology of science and contributes to the field of adult education by investigating the social and material as ontologically entangled. This paper argues that applying multiple sociomaterial concepts helps us to better understand the process of learning and collaboration in the workplace. The third paper is intended as a contribution to practice, specifically to the field of primary care. In this paper, I offer a practical resource that combines theoretical concepts from the first two papers. This paper explores how an awareness of the collaborative process can present practitioners with new ways of approaching collaboration. Across the papers, multiple methods were used to compare primary care collaborations in three distinct time periods during the onset of COVID-19 in Interior British Columbia. First, 15 virtual semi-structured interviews with clinical, administrative, and executive participants were held. Second, a discourse analysis was conducted of Public Health Orders and provincial modelling. Third, dialogic member-checking with the participants was completed. Data were presented in three distinct phases: (1) pre-Wave 1 COVID-19 (January-March 2020); (2) Wave 1 (March-May 2020); and (3) post-Wave 1 (June-August 2020). Data analysis revealed the continually-changing nature of the collaborative process as the construction of boundaries, boundary objects, and assemblages. By better understanding how collaboration and learning is enacted in sociomaterial contexts, this research could potentially improve collaborative outcomes for team members as they strive to enact collaborative policy that is more reflective and efficient.

description: The steady state properties of an interface in a stationary Couette flow are addressed within the framework of fluctuating hydrodynamics. Our study reveals that thermal fluctuations are driven out of equilibrium by an effective shear rate that differs from the applied one. In agreement with experiments, we find that the mean square displacement of the interface is strongly reduced by the flow. We also show that nonequilibrium fluctuations present a certain degree of universality in the sense that all features of the fluids can be factorized into a single control parameter. Finally, the results are discussed in the light of recent experimental and numerical studies.

description: We consider a system of trapped spinless bosons interacting with a repulsive potential and subject to rotation. In the limit of rapid rotation and small scattering length, we rigorously show that the ground state energy converges to that of a simplified model Hamiltonian with contact interaction projected onto the Lowest Landau Level. This effective Hamiltonian models the bosonic analogue of the Fractional Quantum Hall Effect (FQHE). For a fixed number of particles, we also prove convergence of states; in particular, in a certain regime we show convergence towards the bosonic Laughlin wavefunction. This is the first rigorous justification of the effective FQHE Hamiltonian for rapidly rotating Bose gases. We review previous results on this effective Hamiltonian and outline open problems.

description: Previous theoretical studies have shown that measuring the transverse current across DNA strands while they translocate through a nanopore or channel may provide a statistically distinguishable signature of the DNA bases, and may thus allow for rapid DNA sequencing. However, fluctuations of the environment, such as ionic and DNA motion, introduce important scattering processes that may affect the viability of this approach to sequencing. To understand this issue, we have analyzed a simple model that captures the role of this complex environment in electronic dephasing and its ability to remove charge carriers from current-carrying states. We find that these effects do not strongly influence the current distributions due to the off-resonant nature of tunneling through the nucleotides - a result we expect to be a common feature of transport in molecular junctions. In particular, only large scattering strengths, as compared to the energetic gap between the molecular states and the Fermi level, significantly alter the form of the current distributions. Since this gap itself is quite large, the current distributions remain protected from this type of noise, further supporting the possibility of using transverse electronic transport measurements for DNA sequencing.

description: Bibliometric and usage-based analyses and tools highlight the value of information about scholarship contained within the network of authors, articles and usage data. Less progress has been made on populating and using the author side of this network than the article side, in part because of the difficulty of unambiguously identifying authors. I briefly review a sample of author identifier schemes, and consider use in scholarly repositories. I then describe preliminary work at arXiv to implement public author identifiers, services based on them, and plans to make this information useful beyond the boundaries of arXiv.

description: Chorea Huntington (HD) ist eine letal verlaufende erbliche neurodegenerative Erkrankung. Trotz der Identifikation des verantwortlichen Gens im Jahr 1993 sind die genauen molekularen Pathomechanismen bis heute ungeklärt. Bei der Erkrankung kommt es zu typischen unlöslichen Aggregaten des Proteins Huntingtin. Diese Arbeit untersucht die Bildung von Huntingtin Aggregaten in Rattenhirnen der transgenen Rattenline BACHD TG 22. Die Rattenlinie erwies sich als erstes transgenes HD-Tiermodell, in dem sich trotz typischen altersabhängigen Bewegungsstörungen keine Huntingtin-Aggregate nachweisen ließen.
In vivo analysis of blood progenitor differentiation and hematopoietic niche maintenance in Drosophila melanogaster

description: Hematopoiesis is a process where blood cells with distinct functions are produced from hematopoietic stem cells. This process is regulated, both biochemically and biophysically, by a specialized microenvironment called the hematopoietic niche. The niche facilitates blood cell development and maintains blood cell homeostasis. To achieve hematopoietic homeostasis, two critical components are required: 1) a coordinated cell fate decision among hematopoietic stem and progenitor cells and 2) a functional hematopoietic niche that shapes an appropriate signaling environment for the resident stem cells. To gain a fundamental understanding of how the two components are regulated, I use Drosophila hematopoiesis as a genetically tractable model system for studying hematopoiesis. Specifically, I study the behavior of hematopoietic progenitor cells in their endogenous environment (Chapter 2). Next, I build upon these findings to investigate the direct cell-cell communication between hematopoietic progenitor cells (Chapter 3), and the development, regulation, and maintenance of the hematopoietic niche (Chapter 4). In Chapter 2, I develop a long-term whole organ culture system for the Drosophila hematopoietic organ, the lymph gland. Using this approach, I track the location and real-time kinetics of blood cell differentiation and proliferation, both in homeostatic and pathogenic conditions. In Chapter 3, I describe the molecular and cellular mechanism that coordinates the behaviors of hematopoietic progenitors. Specifically, I identify that the hematopoietic progenitors are incorporated in a signaling network that functions to equilibrate information across a large population of progenitors to guide their collective cell fate decision. In Chapter 4, I describe the molecular and cellular mechanism that facilitates the coordination of the activity of hematopoietic niche cells. My findings suggest that the hematopoietic niche is organized in a signaling network established by gap junctions. The network maintains proper niche architecture, allows bi-directional communication between niche cells, and creates a healthy niche microenvironment for developing hematopoietic progenitors. Together, my research provides mechanistic and fundamental insights into how hematopoietic activities are regulated to meet developmental and immunological needs.

description: We analyze the quantum process tomography (QPT) in the presence of decoherence, focusing on distinguishing local and non-local decoherence mechanisms for a two-partite system from experimental QPT data. In particular, we consider the $\sqrt{\rm iSWAP}$ gate realized with superconducting phase qubits and calculate the QPT matrix $χ$ in the presence of several local and non-local decoherence processes. We determine specific patterns of these decoherence processes, which can be used for a fast identification of the main decoherence mechanisms from an experimental $χ$-matrix.

description: The current volume, the third of four, acts as a final report for the excavations that were conducted at Los Pozos, AZ AA:12:91 (ASM) in the fall of 1998. Hoping to build on earlier work conducted by Desert Archaeology at other Early Agricultural period sites along the Santa Cruz, these volumes combine data with those from both seasons at Los Pozos and those garnered from Las Capas to explore the implications of this total body of work for current understanding of this important and lengthy interval in Southwest prehistory. This volume places Los Pozos in the context of what is presently known about the Early Agricultural period in a more general discussion that draws on specific analyses and interpretations contributed by many others.
On the definition, stationary distribution and second order structure of positive semidefinite Ornstein--Uhlenbeck type processes

description: Several important properties of positive semidefinite processes of Ornstein--Uhlenbeck type are analysed. It is shown that linear operators of the form $X\mapsto AX+XA^{\mathrm{T}}$ with $A\in M_d(\mathbb{R})$ are the only ones that can be used in the definition provided one demands a natural non-degeneracy condition. Furthermore, we analyse the absolute continuity properties of the stationary distribution (especially when the driving matrix subordinator is the quadratic variation of a $d$-dimensional Lévy process) and study the question of how to choose the driving matrix subordinator in order to obtain a given stationary distribution. Finally, we present results on the first and second order moment structure of matrix subordinators, which is closely related to the moment structure of positive semidefinite Ornstein--Uhlenbeck type processes. The latter results are important for method of moments based estimation.

description: Actualmente hay 400.000 casos en España de trastornos de la conducta alimentaria, de estos el 90% son mujeres, cada vez siendo más temprana la edad de desarrollo. Son trastornos mentales, donde se cursa sintomatología alimentaria, urgiendo la necesidad de un equipo multidisciplinar para su tratamiento. La sociedad actual sitúa el ideal de belleza en un cuerpo delgado, promocionando utilizar el método que sea necesario para conseguirlo, por eso es importante trabajar la educación nutricional para evitar que esto sea un factor de riesgo en el desarrollo de los trastornos de la conducta alimentaria. Una buena manera de orientar a esta tipología de pacientes sería utilizar como base de alimentación la Dieta Mediterránea, por sus beneficios para la salud y la inclusión de todo tipo de alimentos, trabajando también la flexibilidad alimentaria y rompiendo mitos y creencias que envuelven la nutrición. El objetivo principal del trabajo es la creación de un plan nutricional basado en el diseño de un menú mensual en base a la Dieta Mediterránea y enfocado para los pacientes con trastornos de la conducta alimentaria, diseñando unos algoritmos de apoyo al plan para la creación de un programa informático. Como conclusión, se ha podido observar la falta de consenso y estandarización en el tratamiento dietético-nutricional de los pacientes con este tipo de trastorno y la importancia de incorporar dichos planes.
