Image-based methods to characterize morphological, biomechanical and poroelastic parameters of blood cells and skin tissue
Creators: name: Shrestha, Pranav
Publisher: name: University of British Columbia
Year: 2025

description: Biomedical imaging is a cornerstone of investigations into the state of health/disease in individuals and the mechanics of cells and tissue. In this thesis, we explore different imaging technologies to extract biomechanical properties of blood cells and skin tissue for detecting diseases and optimizing interactions with biomedical devices. Firstly, utilizing high-speed imaging, motion tracking and force measurements, we explore the mechanics of needle insertion into transparent soft solids. A double-insertion technique is applied to determine different force components (deformation, friction, spreading and cutting forces), and estimate toughness for different insertion velocities. The toughness increases with needle velocity (50 N/m to 800 N/m for velocities ≤ 2.5 m/s), and is within the range of toughness for biological and synthetic materials measured by others. The estimates of forces and toughness, and the methods to determine the same, can be used to optimize needle insertions. Secondly, utilizing optical coherence tomography and digital image correlation, we visualize fluid injections in skin tissue and quantify skin tissue deformation. The poroelastic behavior of skin tissue is modelled using a semi-empirical exponential relationship between permeability and strain, and parameters for the permeability-strain model are extracted for skin tissue. The fluid flow estimated by the permeability model with optimized macroscopic parameters matches closely the recorded flow rate, thus validating our semi-empirical model. The semi-empirical model and the model parameters can be used to optimize injection of fluid, such as drugs and vaccines, into skin. Lastly, utilizing low-cost automated microscopy and image analysis techniques, including neural-network based segmentation and machine learning classification, we classify individuals with/without sickle cell disease and β-thalassemia with an overall area under receiver operating characteristic curve, sensitivity and specificity of 0.940, 84.6%, and 92.3%, respectively. The image-based detection technique and 5 other low-cost point-of-care techniques are evaluated against the gold-standard test for 138 participants in Nepal and Canada, to determine the feasibility of using such low-cost point-of-care tests to screen for sickle cell disease β-thalassemia in low-resource and rural/remote settings. Most of the low-cost techniques are suitable for detecting severe disease cases, but only two are suitable for detecting β-thalassemia trait.

description: The idea of measuring distance between languages seems to have its roots in the work of the French explorer Dumont D'Urville \cite{Urv}. He collected comparative words lists of various languages during his voyages aboard the Astrolabe from 1826 to 1829 and, in his work about the geographical division of the Pacific, he proposed a method to measure the degree of relation among languages. The method used by modern glottochronology, developed by Morris Swadesh in the 1950s, measures distances from the percentage of shared cognates, which are words with a common historical origin. Recently, we proposed a new automated method which uses normalized Levenshtein distance among words with the same meaning and averages on the words contained in a list. Recently another group of scholars \cite{Bak, Hol} proposed a refined of our definition including a second normalization. In this paper we compare the information content of our definition with the refined version in order to decide which of the two can be applied with greater success to resolve relationships among languages.

description: A class of oscillating Lorentz covariant configurations for the evolution of the domain walls in diverse dimensions are analytically obtained. It is shown that the oscillating solutions in the case of domain walls are responsible for structures which are larger than the usual kink-like configurations and, in the Lorentz covariant evolution case, lead to long-standing configurations.

description: Studies of random close packing of spheres have advanced our knowledge about the structure of systems such as liquids, glasses, emulsions, granular media, and amorphous solids. When these systems are confined their structural properties change. To understand these changes we study random close packing in finite-sized confined systems, in both two and three dimensions. Each packing consists of a 50-50 binary mixture with particle size ratio 1.4. The presence of confining walls significantly lowers the overall maximum area fraction (or volume fraction in three dimensions). A simple model is presented which quantifies the reduction in packing due to wall-induced structure. This wall-induced structure decays rapidly away from the wall, with characteristic length scales comparable to the small particle diameter.

description: The compound lambda-(BETS)2FeCl4 provides an effective demonstration of the interaction of pi-conduction electron and d-electron localized moment systems in molecular crystalline materials where antiferromagnetic insulating and magnetic field induced superconducting states can be realized. The metal-insulator transition has been thought to be cooperative, involving both the itinerant pi- electron and localized d-electron spins where antiferromagnetic order appears in both systems simultaneously. However, recent specific heat data has indicated otherwise [Akiba et al., J. Phys. Soc. Japan 78,033601(2009)]: although the pi-electron system orders antiferromagnetically and produces a metal-insulator transition, a "mysterious" paramagnetic d-electron state remains. We report 57Fe Mossbauer measurements that support the paramagnetic model, provided the d-electron spins remain in a fast relaxation state below the transition. From the measured hyperfine fields, we also determine the temperature dependence of the pi-d electron exchange field.

Industrial and employee relations

description: Using a labour process lens, this research focuses on the structured antagonism that characterises the employment relationship. This article seeks to further our understanding of how news organisations employ control strategies to extract the labour power of journalists and achieve organisational objectives, and we pay particular attention to the role of editors in this regard. We also explore the responses of journalists as workers to managerial control which can include accommodation, resistance, compliance, or consent. The findings are based on an empirical case study of a local newspaper incorporating interviews with editors and journalists. The case study reveals how journalists’ work intensified with the turn to digital content, and because of reduced staffing since COVID-19, but editors ensured high levels of productivity through distribution of digital analytics and constant monitoring.

description: The operator $L_μ: f \mapsto \int \frac{f(x) - f(y)}{x - y} dμ(y)$ is, for a compactly supported measure $μ$ with an $L^3$ density, a closed, densely defined operator on $L^2(μ)$. We show that the operator $Q = p L_μ^2 - q L_μ$ has polynomial eigenfunctions if and only if $μ$ is a free Meixner distribution. The only time $Q$ has orthogonal polynomial eigenfunctions is if $μ$ is a semicircular distribution. More generally, the only time the operator $p (L_νL_μ) - q L_μ$ has orthogonal polynomial eigenfunctions is when $μ$ and $ν$ are related by a Jacobi shift.
Neutral interstellar hydrogen in the inner heliosphere under the influence of wavelength-dependent solar radiation pressure

Subjects: subject: Astrophysics (astro-ph)

description: With the plethora of detailed results from heliospheric missions and at the advent of the first mission dedicated IBEX, we have entered the era of precision heliospheric studies. Interpretation of these data require precision modeling, with second-order effects quantitatively taken into account. We study the influence of the non-flat shape of the solar Ly-alpha line on the distribution of neutral interstellar H in the inner heliosphere. Based on available data, we (i) construct a model of evolution for the solar Ly-alpha line profile with solar activity, (ii) modify an existing test-particle code used to calculate the distribution of neutral interstellar H in the inner heliosphere so that it takes the dependence of radiation pressure on radial velocity into account, and (iii) compare the results of the old and new version. Discrepancies between the classical and Doppler models appear between ~5 and ~3 AU and increase towards the Sun from a few percent to a factor of 1.5 at 1 AU. The classical model overestimates the density everywhere except for a ~60-degr cone around the downwind direction, where a density deficit appears. The magnitude of the discrepancies appreciably depends on the phase of the solar cycle, but only weakly on the parameters of the gas at the termination shock. For in situ measurements of neutral atoms performed at ~1 AU, the Doppler correction will need to be taken into account, because the modifications include both the magnitude and direction of the local flux by a few km/s and degrees, respectively, which, when unaccounted for, would introduce an error of a few km/s and degrees in determination of the magnitude and direction of the bulk velocity vector at the termination shock.

Coronary revascularization and timing of treatment : comparative effectiveness of PCI and CABG in British Columbia
Creators: name: Hardiman, Sean Christopher
Publisher: name: University of British Columbia
Year: 2024

description: Background: In Canada, clinical need, resource allocation, and variation in demand determine how soon diagnosed ischemic heart disease are treated. Therefore, patients who require non-emergency revascularization by coronary artery bypass graft (CABG) surgery or percutaneous coronary intervention (PCI) may find their procedures are delayed during periods of higher demand for cardiac care or reduced supply of hospital services. Research has shown that some patients who undergo CABG have health outcome benefits compared to those who have PCI and that some delays increase mortality. However, these studies did not account for PCI as an alternative treatment in the event of delay, nor did they consider disease progression or repeat revascularization as outcomes. Using health services research methods, I sought to establish if patients who had delayed CABG would have been better off instead undergoing timely PCI. Methods: I constructed a retrospective cohort consisting of 25,520 BC residents 60 years or older who underwent first-time non-emergency revascularization for angiographically-proven, stable left main or multi-vessel ischemic heart disease in British Columbia between January 1, 2001, and December 31, 2016. In three separate analyses, I compared patients who had delayed CABG with those who had timely PCI on the outcomes of 1) mortality, 2) cardiovascular disease progression, and 3) repeat revascularization. To adjust for between-group differences, I used inverse probability of treatment weights calculated from a propensity score model containing information on patient, structure, and process factors. Results: At three years follow-up, I found that patients who underwent delayed CABG had statistically better outcomes than timely PCI patients: lower mortality, slower cardiovascular disease progression, and fewer repeat revascularizations. Differences favouring delayed CABG were established early across all analyses and maintained throughout the study period. Conclusion: This work suggests that non-emergency patients who wish to receive CABG as their revascularization treatment will not see its benefits attenuated by delay and that PCI may not be suitable as an alternative treatment strategy. This dissertation adds to the knowledge of patients who receive revascularization care, physicians who deliver that care, and policymakers who plan for that care.

description: We present a model example of a quantum critical behavior of renormalized single-particle Wannier function composed of Slater s-orbitals and represented in an adjustable Gaussian STO-7G basis, which is calculated for cubic lattices in the Gutzwiller correlated state near the metal-insulator transition (MIT). The discussion is carried out within the extended Hubbard model and the method of approach proposed earlier [cf. Eur. Phys. J. B {\bf 66}, 385 (2008)]. The component atomic-wave-function size, the Wannier function maximum, as well as the system energy, all scale with the increasing lattice parameter $R$ as $[(R-R_{c})/R_{c}]^{s}$ with $s$ in the interval $[0.9,1.0]$. Such scaling law is interpreted as evidence of a dominant role of the interparticle Coulomb repulsion, which for $R>R_c$ is of intersite character. Relation of the insulator-metal transition lattice-parameter value $R=R_{c}$ to the original {\em Mott criterion} is also obtained. The method feasibility is tested by comparing our results with the exact approach for the Hubbard chain, for which the Mott-Hubbard transition is absent. In view of unique features of our results, an extensive discussion in qualitative terms is also provided.

The characterization of stream and riparian features of importance for fish habitat using laser scanning
Creators: name: Dakin Kuiper, Spencer
Publisher: name: University of British Columbia
Year: 2024

description: Understanding changes in salmonid populations and their habitat is a critical issue given changing climate, their importance as a keystone species, and their cultural significance. Further, there is an increasing need to provide up to date, accurate, and spatially explicit information to forest managers to make informed decisions within a sustainable forest management context. The increasing availability of Airborne Laser Scanning (ALS) data for forest applications offers an opportunity to utilize these data for assessing the quality and quantity of habitat, which is often costly and difficult to characterize at broad scales. ALS data provides detailed and accurate Digital Elevation Models (DEMs) under forest canopies, which in turn enable the characterization of detailed stream networks, as well as stream and terrain attributes important to salmonids. The primary objective of this thesis is to examine the potential of ALS to characterize stream habitat features important for salmonids. To accomplish this a systematic review examining how remote sensing technologies have been used to characterize stream habitat features was completed. Next, workflows and models were developed to extract stream width and individual morphological features classified as pools, riffles, runs, and cascades using ALS data. Additionally, the ability of ALS to extract instream wood features was assessed, examining which ALS and environment attributes influenced the detection rate. Lastly, a broader perspective was used and a framework was developed to integrate ALS derived indicators of watershed condition and pressure into existing watershed status evaluation procedures. Ultimately, the research presented in this thesis describes a series of value-added approaches to better understand how ALS data can be used to characterize stream and riparian vegetation features important to salmonids in a forested environment.

Artificial Immune Systems (AISs) are a biologically-inspired approach which take inspiration from the biological immune system. Interestingly, recent research has show how AISs which use multi-level information sources as input data can be used to build effective algorithms for real time computer intrusion detection. This research is based on biological information fusion mechanisms used by the human immune system and as such might be of interest to the information fusion community. The aim of this paper is to present a summary of some of the biological information fusion mechanisms seen in the human immune system, and of how these mechanisms have been implemented as AISs

description: We analyse the continuum-state and bound-state beta^-decay rates of the neutron. For the calculation of theoretical values of the decay rates we use the new value for the axial coupling constant g_A = 1.2750(9), obtained recently by H. Abele (Progr. Part. Nucl. Phys., 60, 1 (2008)) from the fit of the experimental data on the neutron spin-electron correlation coefficient of the electron energy spectrum of the continuum-state beta^- decay of the neutron. We take into account the contribution of radiative corrections and the scalar and tensor weak couplings. We define correlation coefficients of the electron energy spectrum in terms of axial, scalar and tensor coupling constants. Using recent precise experimental data for the lifetime of the neutron and correlation coefficients we estimate the scalar and tensor weak coupling constants. The bound-state beta^- decay rates of the neutron we calculate as functions of axial, scalar and tensor weak coupling constants. We show that dominantly the neutron decays into hydrogen in the hyperfine states with total angular momentum F = 0. The calculated angular distributions of the probabilities of the bound-state beta^- decays of the polarised neutron can be used for the experimental measurements of the bound-state beta^- decays into the hyperfine states with a total angular momentum F = 1.

To produce these perturbations they used a regime in which the equation of state exponentially rapidly changed during a short time interval. Leaving aside the singularity problem and the difficult question about the possibility to transmit these perturbations from a contracting Universe to the expanding phase, we will show that the methods used in arXiv:0910.2230 are inapplicable for the description of the cosmological evolution and of the process of generation of perturbations in this scenario.

Mapping anomalous subiculum excitatory neurons across circuits and behavior
Creators: name: Erwin, Sarah Rae
Publisher: name: University of British Columbia
Year: 2024

description: Subiculum pyramidal neurons form the main output of the hippocampus and are studied as the cellular basis of various aspects of memory and spatial navigation. Increasing evidence has demonstrated a great deal of heterogeneity within the subiculum, from intrinsic cell properties to connectivity and function. Recent single-cell RNA sequencing analysis has identified a sparse, transcriptomically distinct population of subiculum excitatory neurons, marked by high expression of the gene Ly6g6e. Utilizing a transgenic mouse line that allows cre-mediated cell-type-specific access of these cells, this research investigates the morphology, connectivity, and activity correlates of this unique subpopulation. Leveraging this transgenic line with cell-type-specific viral tracing tools and whole brain clearing, we discovered that this neuronal population occupies the deepest layer of the subiculum, displays unique morphological properties, and forms dedicated axonal projections to the anterior thalamic nuclei. Publicly available neuron reconstructions also recapitulate these results. To interrogate potential functional correlates of this population, chemogenetic activity silencing was used during encoding of a novel object recognition (NOR) task. DREADDs-based inhibition of this subpopulation did not produce a behavioral deficit, and histological analysis of activity inhibited cells via fluorescent in situ hybridization (FISH) did not result in decreased immediate early gene (IEG) expression after novel object interaction compared to controls. Considering these results alongside other data from our lab suggests that other methods of manipulating cellular activity may be more suitable for this subpopulation. Motivated by the unique local and long-range structure of this excitatory population and the sustained activity responses seen in vivo, FISH was used to assess potential preferential recruitment of deep subiculum cells via IEG expression following a NOR task. No significant difference in IEG expression was seen between object types; however, this population exhibited a high baseline of activity relative to population abundance. In sum, this data provides evidence for a previously unknown excitatory cell subtype within the subiculum that exhibits unique structural characteristics and sustained activity, and that could play a potentially specialized role in recognition memory.

description: Purpose: Autonomous systems in mechanical thrombectomy (MT) hold promise for reducing procedure times, minimizing radiation exposure, and enhancing patient safety. However, current reinforcement learning (RL) methods only reach the carotid arteries, are not generalizable to other patient vasculatures, and do not consider safety. We propose a safe dual-device RL algorithm that can navigate beyond the carotid arteries to cerebral vessels.
 Methods: We used the Simulation Open Framework Architecture to represent the intricacies of cerebral vessels, and a modified Soft Actor-Critic RL algorithm to learn, for the first time, the navigation of micro-catheters and micro-guidewires. We incorporate patient safety metrics into our reward function by integrating guidewire tip forces. Inverse RL is used with demonstrator data on 12 patient-specific vascular cases.
 Results: Our simulation demonstrates successful autonomous navigation within unseen cerebral vessels, achieving a 96% success rate, 7.0s procedure time, and 0.24 N mean forces, well below the proposed 1.5 N vessel rupture threshold.
 Conclusion: To the best of our knowledge, our proposed autonomous system for MT two-device navigation reaches cerebral vessels, considers safety, and is generalizable to unseen patient-specific cases for the first time. We envisage future work will extend the validation to vasculatures of different complexity and on in vitro models. While our contributions pave the way towards deploying agents in clinical settings, safety and trustworthiness will be crucial elements to consider when proposing new methodology.

description: The discovery that the cosmic expansion is accelerating has been followed by an intense theoretical and experimental response in physics and astronomy. The discovery implies that our most basic notions about how gravity work are violated on cosmological distance scales. One simple fix is the introduction of a cosmological constant into the field equations for general relativity. However, the extremely small value of the cosmological constant, relative to theoretical expectations, has led theorists to explore a wide variety of alternative explanations that involve the introduction of an exotic negative-pressure fluid or a modification of general relativity. Here we briefly review the evidence for cosmic acceleration. We then survey some of the theoretical attempts to account for it, including the cosmological constant, quintessence and its variants, mass-varying neutrinos, and modifications of general relativity, such as scalar-tensor and $f(R)$ theories and braneworld scenarios. We discuss experimental and observational tests that may allow us to distinguish between some of the theoretical ideas that have been put forward.

description: The high specific surface area graphene sheets with good crystallization could readily be obtained from graphite through weak oxidation, intercalation and exfoliation in alkaline solution. The influence factors of the ratio of C to KMnO4 and the water bath temperature for synthesis of few-layers graphene (FLG) have been systematically investigated. The graphene with high specific surface area of 2013 m2·g−1 and layer numbers of 4–6 were obtained under the ratio of C to KMnO4 of 1:1 and the water bath temperature of 15 °C. In addition, the synthesis mechanism of FLG was analyzed in details. The oxidation occurred in interface locations while sulfate radicals were simultaneously intercalated into the graphite flake, and finally FLG was formed in alkaline condition with the aid of ultrasound. Meanwhile, the electrochemical properties of FLG were investigated as FeC2O4/graphene composite (FGC) for the anode of lithium ion battery. Graphene with a few layers, large specific surface area, and high electrical conductivity was beneficial to improve the cycling performance of FeC2O4 anode. Therefore, the FGC displayed a large reversible capacity of 903 mAh·g−1 in the initial cycle at a current density of 500 mA·g−1 and an excellent cyclic performance of 737 mAh·g−1 after 200 cycles.

description: The hydrological characteristics of water basins in Pernik region, Bulgaria have been badly worsened since the summer of 2019. This study was performed in the low-flow period of December 2019 and covered eight sampling stations along the Struma River between Studena dam and Pchelina dam, region of the town of Pernik. The analytical data obtained and the calculated threshold pollution indices of the single nutrients PO4 3-, NO2 – , NO3 – and NH4 + and their integrated threshold pollution indices showed water pollution in respect of PO4 3- and NH4 + . The concentrations of PO4 3- at all stations, of NH4 + ions in the waters after Pernik city, and of NO3 – and NO2 – before Pchelina dam exceeded the respective maximum allowed concentrations (MAC) according to the Bulgarian legislation. The waters were pure in respect of the trace metals Al, Fe, Co, Ni, Cu, Zn, Cd, and Pb; only Mn exceeded its MAC. The chemical species of the trace metals were calculated by thermodynamic modeling and discussed on the base of the “Hard and Soft Acids and Bases” (HSAB) principle.

description: Let $k$ be an algebraically closed field of characteristic 2, and let $G$ be a finite group. Suppose $B$ is a block of $kG$ with dihedral defect groups such that there are precisely two isomorphism classes of simple $B$-modules. The description by Erdmann of the quiver and relations of the basic algebra of $B$ is usually only given up to a certain parameter $c$ which is either 0 or 1. In this article, we show that $c=0$ if there exists a central extension $\hat{G}$ of $G$ by a group of order 2 together with a block $\hat{B}$ of $k\hat{G}$ with generalized quaternion defect groups such that $B$ is contained in the image of $\hat{B}$ under the natural surjection from $k\hat{G}$ onto $kG$. As a special case, we obtain that $c=0$ if $G=\mathrm{PGL}_2(\mathbb{F}_q)$ for some odd prime power $q$ and $B$ is the principal block of $k \mathrm{PGL}_2(\mathbb{F}_q)$.

Non-linear spin wave theory results for the frustrated S = 1/2 Heisenberg antiferromagnet on a body-centered cubic lattice

description: At zero temperature the sublattice magnetization of the quantum spin-1/2 Heisenberg antiferromagnet on a body-centered cubic lattice with competing first and second neighbor exchange (J1 and J2) is investigated using the non-linear spin wave theory. The zero temperature phases of the model consist of a two sublattice Néel phase for small J_2 (AF_1) and a collinear phase at large J_2 (AF_2). We show that quartic corrections due to spin-wave interactions enhance the sublattice magnetization in both the AF_1 and the AF_2 phase. The magnetization corrections are prominent near the classical transition point of the model and in the J_2> J_1 regime. The ground state energy with quartic interactions is also calculated. It is found that up to quartic corrections the first order phase transition (previously observed in this model) between the AF_1 and the AF_2 phase survives.

description: We investigate the microscopic mechanisms giving rise to plastic depinning and irreversible flow in vortex matter. The topology of the vortex array crucially determines the flow response of this system. To illustrate this claim, two limiting cases are considered: weak and strong pinning interactions. In the first case disorder is strong enough to introduce plastic effects in the vortex lattice. Diffraction patterns unveil polycrystalline lattice topology with dislocations and grain boundaries determining the electromagnetic response of the system. Filamentary flow is found to arise as a consequence of dislocation dynamics. We analize the stability of vortex lattices against the formation of grain boundaries, as well as the steady state dynamics for currents approaching the depinning critical current from above, when vortex motion is mainly localized at the grain boundaries. On the contrary, a dislocation description proves no longer adequate in the second limiting case examined. For strong pinning interactions, the vortex array appears completely amorphous and no remnant of the Abrikosov lattice order is left. Here we obtain the critical current as a function of impurity density, its scaling properties, and characterize the steady state dynamics above depinning. The plastic depinning observed in the amorphous phase is tightly connected with the emergence of channel-like flow. Our results suggest the possibility of establishing a clear distinction between two topologically disordered vortex phases: the vortex polycrystal and the amorphous vortex matter.

description: Preclinical studies provide valuable insights into disease mechanisms, potential treatments, and therapeutic strategies before clinical trials in the studies of retinal diseases. Mouse, one of the most widely used small animals for preclinical studies, possess great advantages as experimental animals based on their easy accessibility and availability which make them an ideal animal with a broad range of pathological models. Optical coherence tomography (OCT) allows non-invasive in vivo imaging that generates high-resolution 3D images and has been successfully applied in ophthalmology. Also, the recent progress in the development of functional extensions of OCT allowed the generation of multiple contrasts providing information-rich images. This thesis focuses on the development and verification of a polarization-diversity OCT (PD-OCT) system tailored for the mouse retina to acquire high-resolution multi-contrast images. The implementation of a sensorless adaptive optics technique and a multiple spectrometer calibration method ensures the capture of retinal images with an advanced resolution while precisely detecting melanin contrast. Preclinical application of PD-OCT demonstrated its efficacy in visualizing fine retinal features in multiple contrasts with the help of the 3D image registration technique.

description: In this letter we study the observed distributions of rotational velocity in a sample of more than 16,000 nearby F and G dwarf stars, magnitude complete and presenting high precision $Vsin i$ measurements. We show that the velocity distributions cannot be fitted by a maxwellian. On the other hand, an analysis based on both Tsallis and Kaniadakis power-law statistics is by far the most appropriate statistics and give a very good fit. It is also shown that single and binary stars have similar rotational distributions. This is the first time, to our knowledge, that these two new statistics are tested for the rotation of such a large sample of stars, pointing solidly to a solution of the puzzling problem on the function governing the distribution of stellar rotational velocity
