title: The phytoglobin-nitric oxide cycle: a transgenic approach to studying hypoxic stress in plants
Creators: name: Cochrane, Devin W.
Publisher: name: Memorial University of Newfoundland
Year: 2021

description: Hypoxic stress is one of the most common abiotic stresses plants face. Without sufficient oxygen to drive mitochondrial respiration, plants undergo an energy crisis. To combat this, a form of nitrite driven respiration called the phytoglobin-nitric oxide cycle is induced to maintain minimal ATP production. I studied the effects of overexpression and knockdown of the class-1 phytoglobin (Pgb) gene in barley (Hordeum vulgare L.) and the alternative oxidase (AOX) gene in tobacco (Nicotiana tabacum) in low-oxygen conditions to gain a better understanding of their roles in the hypoxic stress response. NO production was significantly lower in AOX knockdown plants compared to wild type and AOX overexpressing plants. The knockdown of AOX resulted in the increased level of protein S-nitrosylation under normoxia and the decreased S-nitrosylation under hypoxia. Under both conditions, there were complex differences in the pool size of amino and organic acids, depending upon AOX amount. Specifically under hypoxia, AOX amount strongly influenced the mitochondrial, but not cytosolic, activity of aconitase, which is known to be inactivated by NO and superoxide. Under normoxia and during reoxygenation after hypoxia, the knockdown of AOX increased the amount of superoxide, lipid peroxidation (malondialdehyde content) and total antioxidant reducing power. Hence, AOX has pervasive and oxygen concentration-dependent effects on NO production and protein S-nitrosylation, respiratory carbon and nitrogen flow, as well as on the metabolism of reactive oxygen species. The overexpression of phytoglobin lowered the amount of NO released, while knockdown significantly stimulated NO emission. The overexpression of phytoglobin corresponded to higher ATP/ADP ratios, pyrophosphate levels and aconitase activity under anoxia, while knockdown of phytoglobin resulted in the increased level of protein nitrosylation, elevation of alcohol dehydrogenase and nitrosoglutathione reductase activities. The overexpressing plants showed various signs of stunted growth under normoxia, but were the only type to germinate and survive under hypoxia. These results show that overexpression of phytoglobin protects plant cells via NO scavenging and improves their low-oxygen stress survival. However, it may not be useful for cereal crop improvement since it comes with a significant interference with normoxic NO signalling pathways.

description: This paper presents a novel alternative to the classical real number continuum. Based on a cyclic and fractally quantized number space defined over the interval [0,11], the proposed model replaces uncountable cardinality with a countable, resonance-based structure. It eliminates the need for the Continuum Hypothesis and provides a coherent, information-preserving framework that may serve as a foundation for both mathematical and physical theories. The approach is fully deterministic, computable, and structured through prime-based difference sequences.

 

The work is conceptually connected to the author’s earlier work on number space quantization through prime-difference sequences

(“A New Perspective on Infinite Number Spaces through Prime Number Distances and Quantization” – DOI: 10.5281/zenodo.14853309),

title: Inclusions and exclusions in the Irish literary canon in the mid-twentieth century
Creators: name: Kao, Wei-Hung
Publisher: name: University of Kent
Year: 2004

description: This thesis explores how a variety of political, religious and social determinants counterbalanced each other to legitimise a new canon, or canons, in post-Treaty Ireland. 'Participants' to be discussed in the making of the Irish canon included members of the Educational Board, university faculties, clerics, textbook editors and anthologists, historians, creative writers, literary critics, politicians, censors, and so on. The different traditions and perspectives they represent complicate the formulation of the canon through which many antagonistic ideologies give shape to the various versions of Irishness. The thesis also examines how and why some writers did not attract critical attention in mid-twentieth century Ireland, and what kinds of writing were deemed most 'canonical', when political and religious ideologies were more influential than other factors. To demonstrate how the formation of the Irish nation had impacts on the making of an Irish canon, this thesis will discuss relevant issues at institutional and textual levels. The institutional, as the first three chapters will elaborate, will focus on Irish education from primary to tertiary levels. These three chapters will reveal how the teaching of Irish literature might have significantly de-Anglicised Irish pupils, and how it sought to secure an Irish national identity. The latter four chapters, following the demonstration of the success and failure, of educational de-Anglicisation, will draw attention to literary works per se, to see why certain choices of themes would be admitted to, or left out of, the canon, and under what circumstances. Although both anthologists and many creative writers were interested in the topics of Irish history, the latter seemed to be more capable of introducing historical subjects from non-nationalistic or sometimes comic or feminist perspectives -- which caused some of their works to be dismissed from the nationalistic canon. The writers to be discussed in this thesis include Daniel Corkery, J. Q Farrell, Denis Johnston, Mary Lavin, Iris Murdoch, Kate O'Brien, Frank O'Connor, Liam O'Flaherty, and James Plunkett.

description: To evaluate the epidemiology, healthcare resource utilization, and direct healthcare costs associated with Huntington’s disease in a Canadian setting with a universal healthcare system. Using Albertan administrative health data, a retrospective cohort was identified applying an algorithm requiring two HD diagnostic codes within two years, using the first record as the index date (i.e. proxy for diagnosis date), from 1 April 2010 to 31 March 2019 for patients ≥21 years old. Incidence/prevalence measures were evaluated from 1 April 2010 to 31 March 2019, while healthcare resource utilization and healthcare costs per person-year (inflated to 2020 Canadian dollars) were evaluated from index to the end of follow-up (death, moved out of province, or 31 March 2020). Mean [standard deviation] age at index (n = 395) was 53.9 [13.8] years and 53.7% were female. From 2010 to 2019, annual HD incidence varied between 0.47 and 1.21/100,000 person-years and HD prevalence increased from 7.25 to 9.33/100,000 persons. The mean number of visits per person-year for general and specialist practitioners was 19.2 [18.8] and 12.2 [25.5], respectively. The mean total all-cause direct healthcare costs were $23,211 [$38,599] per person-year, with hospitalizations accounting for 57.8% of all-cause costs. Costs were higher among individuals with a long-term care stay, a proxy for disease severity. This study utilizes administrative health data to describe the epidemiology of HD and utilization of publicly funded care by individuals with HD. While administrative data presents limitations since it is not collected for research purposes, it provides a population-level examination of the burden of HD. There was a substantial economic burden associated with HD in a Canadian setting.
Rheology and flow dynamics of wormlike micellar gels

description: Long-chained zwitterionic surfactants form wormlike micellar (WLM) gels in solution at room temperature and revert back to a Maxwell viscoelasticity at higher temperatures. We study the rheology and flow dynamics of such WLM gels using a combination of rheometry and flow experiments. First, we rheologically characterize the material and reveal details of its microstructure along with signatures of shear-induced fracture and banding. Then we pump these WLM gels in a capillary pipe and measure the development of velocity profiles in time. Our experiments capture flow features like strong slip, plug and shear layers along with flow-induced heterogeneity. In the third part of the thesis we study droplet detachment and filament thinning of our WLM gels. We show the existence of elastocapillary thinning regimes, power-law failure and discuss dependencies of said dynamics on surfactant concentration. Our experiments reveal hitherto unknown complex dynamics even in simple flows of WLM gels and is likely to inform research on flows where rheology and transient fluid dynamics of similar soft matter systems play a crucial role.

Reconstructing Vancouver's black community from the history of invisibility : analysis of the role of black entrepreneurship in British Columbia, Canada
Creators: name: Mohamed, Majda
Publisher: name: University of British Columbia
Year: 2023

description: This thesis examines the lived experience of Black-owned businesses in Vancouver, identifying and analyzing the practices and processes of being an African diaspora at the local level. The discussion is on how the discourses of community, nation, and race have impacted the economic prosperity within the Black community as a collective. The study will travel back in time and unravel the complex racial history of Canada and determine how racial beliefs, attitudes, and discrimination continue to be directed at people of African descent, particularly here in British Columbia. Understanding the relationship between race and colonial history will, therefore, determine the barriers that hinder the growth of black entrepreneurship in Vancouver and prove the necessity to facilitate future Black entrepreneurs to overcome economic, social, political, and psychological adversity. The city of Vancouver is undergoing a series of reconciliations for marginalized communities. In the plan, the city is committed to facilitating for the African diaspora community after urban racial policies caused the displacement of a historic black neighborhood, formally known as Hogans Alley. Therefore, the findings will frame attempts to envision and support black businesses in the future development of Hogans Alley and encourage scholars, policymakers, and practitioners to build a healthier and more inclusive city.

Year: 2023

description: This study demonstrated a method that can characterize the development of FLASH and conventional radiotherapy-induced pulmonary complications with in vivo respiratory-gated micro-CT imaging methods in free-breathing mice. Thirty C57BL/6 mice were selected for this research project. Baseline respiratory-gated micro-CT images of individuals were collected a week before receiving treatments. During each imaging session, we collected two images for the end-expiration and peak-inspiration phases. Mice were equally distributed into five groups after baseline respiratory-gated micro-CT imaging sessions to receive different radiation treatments. Treatments administered included no irradiated, 10 MV photon ultra-high dose-rate radiotherapy (FLASH-RT) and conventional radiotherapy at two dose levels 15 Gy and 30 Gy targeting on lungs. Mice received repeated respiratory-gated micro-CT scans up to 24 weeks post treatment. For data analysis, regions of interest were drawn starting 2 mm above the carina and covering the entire lung. After selecting threshold numbers, we did semi-manual lung segmentation. The lung's morphological, structural, and functional information was measured to evaluate injuries in pulmonary tissues. Statistics analysis were performed using ANOVA repeated measurement. We monitored the development of lung inflammation, radiation pneumonitis, and fibrosis through respiratory-gated micro-CT images at different timelines, which were also confirmed with histogram analysis. We found significant differences between high-dose conventional and the control groups. Our study showed that the respiratory-gated imaging method can identify the development of pulmonary inflammation and radiation. The murine model suggested that conventional radiation treatment had more severe complications than the FLASH group. This experimental work is the first study using the in vivo respiratory-gated imaging method to monitor the progression of 10 MV photon FLASH-RT-induced pulmonary complications in free-breathing mice.

description: Statistical process control (SPC) charts are widely used in the manufacturing industry for monitoring the performance of sequential production processes over time. A common practice in using a control chart is to first collect samples and take measurements of certain quality variables from them at equally-spaced sampling times, and then make decisions about the process status by the chart based on the observed data. In some applications, however, the quality variables are associated with certain covariates, and it should improve the performance of an SPC chart if the covariate information can be used properly. Intuitively, if the covariate information indicates that the process under monitoring is likely to have a distributional shift soon based on the established relationship between the quality variables and the covariates, then it should benefit the process monitoring by collecting the next process observation sooner than usual. Motivated by this idea, we propose a general framework to design a variable-sampling control chart by using covariate information. Our proposed chart is self-starting and can well accommodate stationary short-range serial data correlation. It should be the first variable-sampling control chart in the literature that the sampling intervals are determined by the covariate information. Numerical studies show that the proposed method performs well in different cases considered.

Svelato il mistero di ‘Oumuamua

Publisher: name: Media Inaf

Secondo un modello pubblicato oggi su Nature, la forza di tipo non-gravitazionale che ha agito su 'Oumuamua durante la fase di allontanamento dal Sole può essere spiegata per mezzo del degassamento dell'idrogeno molecolare creato dall'interazione dei raggi cosmici sul ghiaccio d'acqua che, probabilmente, si trova sotto la superficie del corpo celeste. Si spiega così l'accelerazione anomala di 'Oumuamua, senza bisogno di invocare ipotesi esotiche come iceberg di idrogeno o sonde aliene. Molto probabilmente 'Oumuamua è una cometa oscura

Out-of-domain few-shot learning for image classification
Creators: name: Walsh, Reece
Publisher: name: University of British Columbia
Year: 2023

description: Deep learning models have consistently produced state-of-the-art results on large, labelled datasets for image classification. Although these models are highly accurate when trained on significant amounts of labeled data, generalization notably suffers when using relatively small datasets or testing on out-of-domain classes. Acquiring new, labelled samples, however, can be an expensive or impractical affair in some situations. In an attempt to address the issue of small dataset sizes, few-shot learning has risen as one prominent area of study that enables models to learn a new task from a very small amount of labelled data. Although techniques in this area have generally succeeded in improving in-domain few-shot capabilities, generalization towards out-of-domain classes remains an open research area. In this work, we address out-of-domain performance in a few-shot setting. To this end, we initially evaluate and experiment with nine state-of-the-art few-shot learning techniques on human cell classification, an out-of-domain task. We subsequently use our findings to formulate three novel techniques for improved out-of-domain few-shot learning. The first technique, Embedding Mixup for Meta-Training, leverages a modified off-line or on-line meta-training phase for improved image classification performance. Our second proposed technique, Fully Self-Supervised Few-Shot Learning, enhances the performance of label efficiency by performing self-supervised, on-line finetuning for label-less in-domain or out-of-domain few-shot learning. Finally, the third proposed technique, Masked Autoencoders for Few-Shot Learning, generates new embeddings that reinforce few-shot accuracy on in-domain and out-of-domain settings. The aforementioned techniques are extensively evaluated on standard in-domain and out-of-domain datasets to illustrate the achieved improvement in generalization and robustness towards unseen data. Overall, we show that our proposed work is capable of improving performance by up to 16% on both out-of-domain and in-domain datasets.

description: Nancy Grace Roman Space Telescope would discover a large number of transients which exhibits a wide variety of diversity in light curves. It is important for us to model photometric light curves with a small number of parameters through PCA (Principal Component Analysis). PCA can be used for simulations, and it works well with machine learning techniques. For Roman Space Telescope data, we can apply PCA for classifications and light curve fitting. We demonstrate PCA application on both time series and diversity / classifications, and show only a few parameters are needed to describe the time series and diversity.
