description: Genotoxic stress during DNA replication constitutes a serious threat to genome integrity and causes human diseases. Defects at different steps of DNA metabolism are known to induce replication stress, but the contribution of other aspects of cellular metabolism is less understood. We show that aminopeptidase P (APP1), a metalloprotease involved in the catabolism of peptides containing proline residues near their N-terminus, prevents replication-associated genome instability. Functional analysis of C. elegans mutants lacking APP-1 demonstrates that germ cells display replication defects including reduced proliferation, cell cycle arrest, and accumulation of mitotic DSBs. Despite these defects, app-1 mutants are competent in repairing DSBs induced by gamma irradiation, as well as SPO-11-dependent DSBs that initiate meiotic recombination. Moreover, in the absence of SPO-11, spontaneous DSBs arising in app-1 mutants are repaired as inter-homologue crossover events during meiosis, confirming that APP-1 is not required for homologous recombination. Thus, APP-1 prevents replication stress without having an apparent role in DSB repair. Depletion of APP1 (XPNPEP1) also causes DSB accumulation in mitotically-proliferating human cells, suggesting that APP1's role in genome stability is evolutionarily conserved. Our findings uncover an unexpected role for APP1 in genome stability, suggesting functional connections between aminopeptidase-mediated protein catabolism and DNA replication.

description: Methods of three-dimensional deconvolution with a point-spread function as frequently employed in optical microscopy to reconstruct true three-dimensional distribution of objects are extended to holographic reconstructions. Two such schemes have been developed and are discussed: an instant deconvolution using the Wiener filter as well as an iterative deconvolution routine. The instant 3d-deconvolution can be applied to restore the positions of volume-spread objects such as small particles. The iterative deconvolution can be applied to restore the distribution of complex and extended objects. Simulated and experimental examples are presented and demonstrate artifact and noise free three-dimensional reconstructions from a single two-dimensional holographic record.

description: This methodological article aims to elucidate the theoretical aspects of quantile regression, advocating for its broader recognition and utilization as a predictive tool. Despite its utility, quantile regression remains relatively obscure. To enhance comprehension and facilitate its application, we illustrate its implementation through an example in the domain of social and health psychology, specifically focusing on attitudes towards individuals living with HIV/AIDS. By providing a practical demonstration within this context, we aim to demystify quantile regression and highlight its relevance in various fields of research.
System integration, parametric study and temperature prediction using machine learning in direct energy deposition
Creators: name: Bayat, Erfan
Publisher: name: University of British Columbia
Year: 2023

description: In Direct Energy Deposition (DED), the melt pool temperature is a critical control parameter that affects deposition rate, porosity formation, residual stress, and microstructure in the final parts. In this thesis, a data-driven approach using Machine Learning (ML) models is used to predict the melt pool temperature using experimental data. This thesis presents the integration of the laser-based DED system using metal powder feedstock, the determination of the process parameter window for the setup, and the development of an ML pipeline to predict the melt pool temperature based on its history. In the system integration for the DED system, a laser generator, powder feeder, deposition head, and sensors (i.e., an IR camera and a 2-wavelength pyrometer) were integrated into an existing 3-axis motion stage. Python-based software was developed to control the laser generator and to read data from the sensors. The software calibrates the IR camera’s temperature, which is highly dependent on the emissivity, by leveraging the data from the 2-wavelength pyrometer. To determine the process parameter window, 150 single-layer clads were deposited; clads’ crosssections were polished and etched, and optical microscopy was used to measure the clad’s height, melt pool’s depth, and dilution ratio. Analysis was conducted on the correlation of the process parameters, laser power, scan speed, flow rate, and the measured properties of the clads. The process parameters with the minimal dilution of (5-25%) were selected to obtain clads with proper geometry and bonding to the substrate. Finally, the temperature data of a 6-layer thin wall with the obtained process parameters were used to train several ML models, including Dense Neural Networks (DNN), 1-Dimensional Convolutional Neural Networks (1D-CNN), Recurrent Neural Networks (RNN), Long Short-Term Memory (LSTM), and Gated Recurrent Unit (GRU). LSTM shows better performance among these models; therefore it was implemented in the ML pipeline for temperature prediction. The Model can predict the trend and fluctuations of the melt pool temperature with higher accuracy compared to the existing models for melt pool temperature prediction in the DED process.

description: (Abridged) We explore the role of X-ray photoevaporation in the evolution and dispersal of viscously evolving T-Tauri discs. We show that the X-ray photoevaporation wind rates scale linearly with X-ray luminosity, such that the observed range of X-ray luminosities for solar-type T-Tauri stars (10e28-10e31 erg\s) gives rise to vigorous disc winds with rates of order 10e-10-10e-7 M_sun/yr. We use the wind solutions from radiation-hydrodynamic models, coupled to a viscous evolution model to construct a population synthesis model so that we may study the physical properties of evolving discs and so-called `transition discs'. Current observations of disc lifetimes and accretion rates can be matched by our model assuming a viscosity parameter alpha = 2.5e-3. Our models confirm that X-rays play a dominant role in the evolution and dispersal of protoplanetary discs giving rise to the observed diverse population of inner hole `transition' sources which include those with massive outer discs, those with gas in their inner holes and those with detectable accretion signatures. To help understand the nature of observed transition discs we present a diagnostic diagram based on accretion rates versus inner hole sizes that demonstrate that, contrary to recent claims, many of the observed accreting and non accreting transition discs can easily be explained by X-ray photoevaporation. Finally, we confirm the conjecture of Drake et al. (2009), that accretion is suppressed by the X-rays through `photoevaporation starved accretion' and predict this effect can give rise to a negative correlation between X-ray luminosity and accretion rate, as reported in the Orion data.

description: Designing an m-bar linkage with a maximal number of assembly modes is important in robot kinematics, and has further applications in structural biology and computational geometry. A related question concerns the number of assembly modes of rigid mechanisms as a function of their nodes n, which is uniquely defined given m. Rigid 11-bar linkages, where n=7, are the simplest planar linkages for which these questions were still open. It will be proven that the maximal number of assembly modes of such linkages is exactly 56. The rigidity of a linkage is captured by a polynomial system derived from distance, or Cayley-Menger, matrices. The upper bound on the number of assembly modes is obtained as the mixed volume of a 5x5 system. An 11-bar linkage admitting 56 configurations is constructed using stochastic optimisation methods. This yields a general lower bound of $Ω(2.3^n)$ on the number of assembly modes, slightly improving the current record of $Ω(2.289^n)$, while the best known upper bound is roughly $4^n$. Our methods are straightforward and have been implemented in Maple. They are described in general terms illustrating the fact that they can be readily extended to other planar or spatial linkages. The main results have been reported in conference publication [EM11]. This version (2017) typesets correctly the last Figure 5 so as to include all 28 configurations modulo reflection.

description: This paper is about the family of smooth quartic surfaces $X \subset \mathbb{P}^3$ that are invariant under the Heisenberg group $H_{2,2}$. For a very general such surface $X$, we show that the Picard number of $X$ is 16 and determine its Picard group. It turns out that the general Heisenberg invariant quartic contains 320 smooth conics and that in the very general case, this collection of conics generates the Picard group.

description: The DARPA program ‘Systematizing Confidence in Open Research and Evidence' (SCORE) aims to generate confidence scores for a large number of research claims from empirical studies in the social and behavioural sciences. The confidence scores will provide a quantitative assessment of how likely a claim will hold up in an independent replication. To create the scores, we follow earlier approaches and use prediction markets and surveys to forecast replication outcomes. Based on an initial set of forecasts for the overall replication rate in SCORE and its dependence on the academic discipline and the time of publication, we show that participants expect replication rates to increase over time. Moreover, they expect replication rates to differ between fields, with the highest replication rate in economics (average survey response 58%), and the lowest in Psychology and in Education (average survey response of 42% for both fields). These results reveal insights into the academic community's views of the replication crisis, including for research fields for which no large-scale replication studies have been undertaken yet.

This lays the foundation for classification results of more general classes of Newton maps. A fundamental ingredient is the proof that for every Newton map (postcritically finite or not) every connected component of the basin of an attracting fixed point can be connected to $\infty$ through a finite chain of such components.

description: The velocity auto-correlation spectra of simple liquids obtained by the NMR method of modulated gradient spin echo show features in the low frequency range up to a few kHz, which can be explained reasonably well by a $t^{-3/2}$ long time tail decay only for non-polar liquid toluene, while the spectra of polar liquids, such as ethanol, water and glycerol, are more congruent with the model of diffusion of particles temporarily trapped in potential wells created by their neighbors. As the method provides the spectrum averaged over ensemble of particle trajectories, the initial non-exponential decay of spin echoes is attributed to a spatial heterogeneity of molecular motion in a bulk of liquid, reflected in distribution of the echo decays for short trajectories. While at longer time intervals, and thus with longer trajectories, heterogeneity is averaged out, giving rise to a spectrum which is explained as a combination of molecular self-diffusion and eddy diffusion within the vortexes of hydrodynamic fluctuations.

description: How to optimize the allocation of enzymes in metabolic pathways has been a topic of study for many decades. Although the general problem is complex and nonlinear, we have previously shown that it can be solved by convex optimization. In this paper, we focus on unbranched metabolic pathways with simplified enzymatic rate laws and derive analytic solutions to the optimization problem. We revisit existing solutions based on the limit of mass-action rate laws and present new solutions for other rate laws. Furthermore, we revisit a known relationship between flux control coefficients and enzyme abundances in optimal metabolic states. We generalize this relationship to models with density constraints on enzymes and metabolites, and present a new local relationship between optimal reaction elasticities and enzyme amounts. Finally, we apply our theory to derive simple kinetics-based formulae for protein allocation during bacterial growth.
Antibacterial properties of a novel dental adhesive loaded with gold nanoshells for photothermal therapy applications
Creators: name: Darvish, Shayan
Publisher: name: University of British Columbia
Year: 2023

description: Introduction: Dental caries is a common chronic oral disease, posing an important health impact and economic burden on the society. Photothermal therapy (PTT) is an innovative approach being used in cancer therapy, and gold nanoparticles (AuNPs) may be used as a photothermal agent (PTTA). This work explored the antibacterial potential of an experimental methacrylate-based dental resin loaded with AuNPs via PTT. Methods: A hydrophobic dental resin consisting of 70wt% Bisphenol-A-Dimethacrylate (BisEMA), 26wt% Tetraethylene-glycol-dimethacrylate (TEEGDMA), 2wt% photo-initiators, and 2wt% ethanol was prepared. Then, 120 nm gold nanoshells were added to the blend at loading concentrations: 0%, 1×10¹⁰ particles/mL (i.e., 0.01wt%) and 2×10¹⁰ particles/mL (i.e., 0.02wt%). Fourier-transform infrared (FTIR) spectroscopy was first used to assess the degree of conversion of the experimental blends following photopolymerization (740-760mW/cm²). A 20-hr Minimum Inhibitory Concentration (MIC) test was performed on irradiated solutions of AuNPs (200 to 0µg /mL) with planktonic Streptococcus mutans (S. mutans) in brain heart infusion media. Light treatments were: 1) Dark; 2) 15minute LED (660 nm, 11.1 J/cm²); 3) 30minute LED (660 nm, 22.2 J/cm²); and 4) 30second laser+2mm distance (95.5 J/cm²). Colony Forming Unit (CFU) count assay was then performed on 6mm-diameter resin disks following 24hr growth of a S. mutans biofilm. Light treatment for the CFU assay were: 1) Dark; 2) 30minute LED (22.2 J/cm²); 3) 60minute LED (44.4 J/cm²); 4) 30second laser+2mm distance (95.5 J/cm²); and 5) 30second laser+4mm distance (23.9 J/cm²). Data was analyzed by ANOVA (SPSS, α=0.05) followed by a post-hoc Tukey comparison. Results: The MIC results showed a reduction in planktonic S. mutans at 0.78µg/mL (P=0.009), 1.56 µg/mL (P<0.001), and 3.12 µg/mL (P<0.001) AuNPs under the laser illumination compared to the dark condition. However, this was not observed with LED light treatment. The MIC was observed at 100µg/mL for all treatments. Meanwhile, the CFU assay showed no significant dependence on AuNP concentration following any observed light treatment. Conclusion: The AuNPs expressed antibacterial effects following PPT against planktonic S. mutans at low concentrations but not in a polymerized dental adhesive resin. Future studies should focus on different shapes, structure, and concentrations of AuNPs loaded in a resin blend.

title: Design of a PV system including its SCADA for a house in Iran
Creators: name: Zare, Atefeh
Publisher: name: Memorial University of Newfoundland
Year: 2021

description: Solar Radiation in the Middle East is relatively high and is one of the most sustainable renewable sources. However, Iran has not utilized it as one of the most significant sources of energy yet. Considering the mentioned concern, in this Thesis, a PV system is designed using BEopt and Homer software for a house in Golpayegan, Iran. Thermal modeling of the house is done using BEopt software to determine the hourly load consumption profile. The meteorological data and the generated hourly load data are used by Homer software to size the system based on the optimum net present cost. The cost analysis results demonstrate that the PV/grid is the most optimal solution for the under-consideration house. Then a control strategy is proposed to connect the suggested PV system to the electric distribution grid. The proposed control strategy aims to design the Maximum Power Point Tracking (MPPT) algorithm and control the injected active and reactive PV arrays power. The reactive power control provides the PV system with Power Factor Correction (PFC) capability, improving the system's overall performance. Finally, in the last phase of research, a secure, reliable, low-cost, and open-source SCADA system is developed using the most recent SCADA architecture, the Internet of Things. The proposed SCADA system prototype is implemented and tested to measure the temperature, humidity, pressure, and light intensity of a house and control smart home appliances. The results show that the developed open-source SCADA system performs optimally and accurately and could serve as a viable control and monitoring system for PV applications by minor changes.

description: This paper proposes a new approach to multi-sensor data fusion. It suggests that aggregation of data from multiple sensors can be done more efficiently when we consider information about sensors' different characteristics. Similar to most research on effective sensors' characteristics, especially in control systems, our focus is on sensors' accuracy and frequency response. A rule-based fuzzy system is presented for fusion of raw data obtained from the sensors that have complement characteristics in accuracy and bandwidth. Furthermore, a fuzzy predictor system is suggested aiming for extreme accuracy which is a common need in highly sensitive applications. Advantages of our proposed sensor fusion system are shown by simulation of a control system utilizing the fusion system for output estimation.

A virtual parent-mediated intervention to teach robotics coding to autistic youth and their siblings
Creators: name: Marco, Daniela
Publisher: name: University of British Columbia
Year: 2023

description: Many parents find computer science and engineering education valuable and beneficial for their children’s future careers (English, 2015). However, autistic students are underrepresented in science, technology, engineering, and math fields, despite those areas being of strong interest for many autistic individuals (Wei et al., 2013). This study evaluated the effects of a virtual parent-mediated intervention package on the acquisition of robotics coding skills by four elementary-aged autistic youth in home settings. The following additional variables were also explored: (a) the degree to which the parents could implement the intervention package with integrity with autistic youth; (b) the generalization of taught and novel coding skills within sibling play sessions; (c) the parent’s generalization of implementing the intervention package to teach non-autistic siblings the same coding skills; and (d) social validity of parents, children on the autism spectrum, and non-autistic siblings. Results of the multiple baseline across participants design demonstrated all autistic youth were able to acquire the coding skills and generalize taught skills and generate novel tracks and codes during sibling play sessions. Parents were able to implement the intervention package with high treatment integrity and generalize the intervention package to teach non-autistic siblings. Social validity measures indicate families were highly satisfied with the intervention and results. Implications for practitioners, limitations, and future directions are discussed.
Partial Replacement of Cement with Marble Dust Powder

description: The waste generated from the industries cause environmental problems. Hence the reuse of this waste material can be emphasized. Marble Dust Powder (MDP) is a developing composite material that will allow the concrète industry to optimise materiel use, generate economic benefits and build structures that will strong, durable and sensitive to environnement. MDP is by-product obtained during the quarrying process from the parent marble rock; which contains high calcium oxide content of more than 50%. The potential use of MDP can be an ideal choice for substituting in a cementitious binder as the reactivity efficiency increases due to the presence of lime. In this research work, the waste MDP passing through 90 microns, has used for investigating of hardened concrete properties. Furthermore, the effect of different percentage replacement of MDP on the compressive strength, splitting tensile strength (Indirect tensile strength) & flexural strength has been observed. In this experimental study, the effect of MDP in concrete on strength is presented. Five concrete mixtures containing 0%, 5%, 10%, and 20% MDP as cement replacement by weight basis has been prepared. Water/cement ratio (0.43) was kept constant, in all the concrete mixes. Compressive strength, split tensile strength & flexural strength of the concrete mixtures has been obtained at 7 and 28 days. The results of the laboratory work showed that replacement of cement with MDP increase, up to 10% for compressive strength, & up to 15% for split tensile strength & flexural strength of concrete.

description: The Gill Oxygen Limitation Theory (GOLT) is a single unifying theory which uses the geometric constraints of fish gills to explain their growth, reproduction, and ecology. A major aspect of the GOLT describes that with growth, relative oxygen supply declines, leading to a critical hypercapnic/acidic threshold. This threshold is assumed to trigger maturation and explains why the relationship between maximum length (Lmaxᴰ) and length at maturity (Lmᴰ) is conserved across evolutionary distinct fishes (‘D’ represents the growth of the gills). While well documented in bony fishes, this relationship has only been minimally explored in cartilaginous species. This research addresses this knowledge gap through investigation of chimaera, ray, and shark species in which at least one Lmax/Lm data pair could be obtained from the literature. Using multivariate regression modeling, it was shown that Lmaxᴰ/Lmᴰ is similarly conserved across marine Chondrichthyes (Lmaxᴰ/Lmᴰ≈1.14). However, this relationship is lower than seen in bony fish (Lmaxᴰ/Lmᴰ≈1.35), suggesting that cartilaginous species mature at a greater fraction of their maximum size. Following up on this anomaly, it was hypothesized that the high concentrations of urea retained by marine Chondrichthyes (used for osmoregulation) is the likely reason for this delay. This hypothesis was tested through comparison of marine, euryhaline, and freshwater rays which all retain differing concentrations of urea. Modeling among these groups indicated that decreasing urea retention is correlated to an increase in Lmaxᴰ/Lmᴰ. Notably, freshwater rays (no retention of urea) display an Lmaxᴰ/Lmᴰ ratio (≈1.30) almost identical to bony fishes. It is suggested that the carbon dioxide required for urea production allows ureotelic species to offset the critical maturation threshold, through prolonged maintenance of a neutral internal pH, compared to non-ureotelic species. Furthermore, the increased oxygen demands associated with viviparity (live-bearing) is also correlated to a higher Lmaxᴰ/Lmᴰ ratio, independent of phylogeny or habitat. However, analogous to non-viviparous species is a similar relationship between Lmaxᴰ/Lmᴰ and urea retention, implicating the role of the gills and urea in maturation of these species. Overall, this thesis lends strong support to the existence of a critical maturation threshold while also suggesting a role for urea that was previously unknown.

description: Optical coherence tomography (OCT) is a non-invasive optical imaging technique to capture in-vivo, three-dimensional (3D) image data with micrometer resolution. OCT has become a valuable tool for ophthalmologists in detecting and monitoring eye diseases like age-related macular degeneration (AMD), glaucoma, and diabetic retinopathy (DR) by providing valuable information for diagnosis and determining the best course of treatment. OCT angiography (OCTA) is a functional extension of OCT which allows for non-invasive visualization of blood flow in the retina and choroid. OCTA provides detailed information about microvasculature, which is not possible with traditional angiography techniques. However, OCT and OCTA images are susceptible to degradation from motion artifacts induced by the involuntary human subjects’ head and eye movement. Multi-volume acquisition and averaging is a software-based approach to correct the motion artifacts by registering several motion-corrupted images to a single reference image or multiple reference images in a post-processing step. Nonetheless, most software-based algorithms have been more specifically designed for a specific system with a limited field-of-view (FOV) range. In this study, we implemented a robust 3D algorithm for the precise registration of multiple volumes to the coordinates of one volume chosen as the reference volume. Tests were carried out on various datasets obtained from different types of custom-built and commercially available systems to determine the reliability of the proposed algorithm. A two-dimensional (2D) version of this method is then applied to investigate retinal perfusion heterogeneity, which may enhance our understanding of retinal diseases such as glaucoma.

description: Romaine lettuce is a vegetable crop that is frequently contaminated with and often implicated in mass outbreaks of human-pathogenic Escherichia coli. To date, research has focused on the specific pathogens responsible for those outbreaks and consumer- and retail-level interventions to eliminate those pathogens or to mitigate their spread. However, in many cases, no singular food source can be identified. Food microbiomes, particularly those associated phylloplanes, are a growing interest area and may be key in identifying the conditions that allow for proliferation of pathogenic organisms like E. coli O157:H7. Further, examination of dominant components of the lettuce microbiome may reveal suitable candidates that can be encouraged or engineered to outcompete or indicate the presence of pathogens. Until recently, most microbiome studies focused on bacteria; less understood are the fungi of these microbiomes. Many fungi have myriad applications in the prevention and mitigation of both human and plant diseases. Thus, to effectively prevent pathogenic E. coli outbreaks, a fundamental understanding about the fungi that cohabit the lettuce microbiome is paramount. The most frequently isolated yeast in the romaine lettuce microbiome is an undescribed yeast, revealing the dearth of information regarding nonpathogenic fungi in food systems. First, the novel yeast Sporobolomyces lactucae is described using a multi-locus phylogeny through genealogical gene concordance, with a discussion on the potential ecological range. Second, the genome of S. lactucae strain HU9244 is assembled and annotated with transcriptomic information to help guide target gene selection for biotechnology, particularly in identifying candidates for reporter genes that may assist in the detection of E. coli O157:H7 via olfactory or visual cues. Third, the distribution of the yeast S. lactucae is determined, finding the organism in various climate types and potentially on other leafy greens as well, indicating its suitability for in situ detection of foodborne pathogens such as E. coli O157:H7 commonly found on romaine lettuce and other leafy greens.

description: This is empirical research on corporate governance mechanisms. Specifically, this study addresses the potential impact ofthe corporate social responsibility committee (CSRc) on the social pillar score (SP). Based on a sample of 457 listed European companies from the Refinitiv Thomson-Eikon database over a one-year period (2021), this paper examines the effect of the existence of a corporate social responsibility (CSR) committee and the moderating effect of gender diversity on the social pillar score. From our analysis, we show that the more firms have CSR committees, the more likely they are to adopt “socially responsible policies and practices”. In addition, the presence of female directors on the board positively moderates the previous relationship. Therefore, this research stresses that gender diversity in conjunction with CSR committees is a significant predictor of a firm's social initiatives. Thus, our findings show that CSR committees and gender diversity are socially sensitive variables. Finally, the analysis also demonstrates that there is a positive relation between the variables of firm size, board size, role duality and board independence and the social pillar score.

description: We are in the midst of the fourth industrial revolution, and manufacturers are looking
to digitally transform their processes in order to leverage new technologies such as adap-
tive automation, virtual reality and digital twin driven simulation. A key aspect of this
revolution compared to previous is the increased availability of data and accessibility of
machines throughout the production process enabled by cyber-physical systems (CPS) and
IoT. However, the integration of many devices is challenging, requiring significant capital
and expertise. This can limit smaller players from benefiting from technological gains as
well as stymie research, particularly advanced human-computer-interaction (HCI) investiga-
tions which are becoming increasingly relevant.
Thus in this thesis we develop a framework for CPS creation and communication that
is amenable to the needs of HCI and convergence research. We develop several middleware
components to bridge the communication gap of many common fabrication machines and
other devices. The middleware translates device specific protocols into a shared language to
alleviate the user interface (UI) programs of this responsibility and promote reuse. Addi-
tionally, we develop an extension to the glTF model format to leverage this shared protocol
to enable the UI to load and interact with an arbitrary number of devices in an intuitive
manner at runtime. Finally, we discuss several applications to demonstrate the system’s
utility for research.
