Surface nanoengineering of titanium alloys for biomedical applications
Creators: name: Minagar, Sepideh
Publisher: name: Swinburne
Year: 2024

description: Patients who have had an implant of some form in their body not only have to face the challenges of the initial surgery, but also are often left with no choice but to endure a revision surgery. There are several factors responsible for the need for revision surgery, with implant loosening, inflammation and breakage among the most common causes. This thesis focused on modifying the surface of implant to improve the biocompatibility and bioactivity, subsequently eliminating the need for revision surgery. A nanotubular layer was anodised on titanium alloy and the nanoscale characteristics of the nanotubular layer as well as its chemical, physical and biological properties were systematically elucidated. The nanoscale topography of the nanotubes enables bone cells to interlock with them, and improves cell adhesion, proliferation and growth. The bone cell attachment was significantly increased on the nanotubular layers of titania and zirconia fabricated in aqueous and non-aqueous electrolytes.

description: The German Ultrafine Aerosol Network (GUAN) is a cooperative atmospheric observation network, which aims at improving the scientific understanding of aerosol-related effects in the troposphere. The network addresses research questions dedicated to both climate- and health-related effects. GUAN's core activity has been the continuous collection of tropospheric particle number size distributions and black carbon mass concentrations at 17 observation sites in Germany. These sites cover various environmental settings including urban traffic, urban background, rural background, and Alpine mountains. In association with partner projects, GUAN has implemented a high degree of harmonisation of instrumentation, operating procedures, and data evaluation procedures. The quality of the measurement data is assured by laboratory intercomparisons as well as on-site comparisons with reference instruments. This paper describes the measurement sites, instrumentation, quality assurance, and data evaluation procedures in the network as well as the EBAS repository, where the data sets can be obtained.

description: Addressing the detrimental impact of non-stationary environmental noise on automatic speech recognition (ASR) has been a persistent and significant research focus. Despite advancements, this challenge continues to be a major concern. Recently, data-driven supervised approaches, such as deep neural networks, have emerged as promising alternatives to traditional unsupervised methods. With extensive training, these approaches have the potential to overcome the challenges posed by diverse real-life acoustic environments. In this light, this paper introduces a novel neural framework that incorporates a robust frontend into ASR systems in both clean and noisy environments. Utilizing the Aurora-2 speech database, the authors evaluate the effectiveness of an acoustic feature set for Mel-frequency, employing the approach of transfer learning based on Residual neural network (ResNet). The experimental results demonstrate a significant improvement in recognition accuracy compared to convolutional neural networks (CNN) and long short-term memory (LSTM) networks. They achieved accuracies of 98.94% in clean and 91.21% in noisy mode.

description: Background: Roux-en-y gastric bypass (RYGB) surgery produces significant weight loss, however a number of patients experience some and/or complete recidivism of weight years after surgery. Limited research has investigated why patients are experiencing weight regain after surgical interventions. Our objective was to identify appetite-related measures associated with weight regain after RYGB surgery. Methods: Using a cross-sectional design, 29 participants (49.6 ± 9.1 years of age; 29-62 months post-RYGB) were divided into three weight categories; (weight maintainers, n = 9; low weight regainers, n = 10; and high weight regainers, n = 10). Appetite, smell function, eating behaviours and food reward were measured in response to a standardized meal. Results: Weight regain increased significantly in association with time after surgery (rs = 0.768, p = 0.016). High regainers gained on average 8.6 kg/year, compared to low regainers and maintainers, 3.8 ± 0.9 kg/year and 0.9 ± 0.9 kg/year, respectively (p < 0.001). Dietary restraint (using the Three Factor Eating Questionnaire) was significantly higher in weight maintainers and low regainers compared to high regainers using clinical subscales (p < 0.05). Weight regain was associated with higher “liking” of high-fat sweet foods (measured with the Leeds Food Preference Questionnaire) among high weight regainers. Conclusion: Weight regain after RYGB may be associated with higher preferences for high-fat sweet foods, whereas, higher dietary restraint may be associated with lower wanting of high-fat sweet foods among weight maintainers. Findings provide insight into why some patients after RYGB regain weight, while others maintain their weight. Future research is needed to further explore the relationships between appetite-related factors and weight regain after RYGB employing a longitudinal study design.
Temporal and Spatial Trends in Toxic Cyanobacteria as Identified Through Lake Sediment DNA

description: Cyanobacterial and algal blooms can negatively affect water quality particularly when producing toxins that affect human health and wildlife. While reports of blooms are on the rise globally, their underlying causes remain unclear. The goal of this thesis was to determine temporal changes in cyanobacterial abundance and composition through sediment cores in relation to (1) altered land-use leading to cultural eutrophication and (2) warmer air temperatures that have been recorded in the past few decades. This involved evaluating the use of DNA extracted from lake sediments to quantify cyanobacterial abundance and composition. Lake sediments preserved under appropriate storage conditions showed the potential to yield high quality DNA for downstream molecular applications. Cyanobacteria, quantified using the 16S rRNA gene, were found to have increased over the last three decades in comparison to historical averages (since the 1850s) both inside and outside a protected area in western Quebec, Canada, in concert with recent regional warming. Copy numbers of 16S rRNA genes specific to cyanobacteria largely correlated to temporal trends in cyanobacterial pigments. Larger percent increases were seen in cyanobacterial genes in recent times compared to changes in the eubacterial glutamine synthetase (glnA) gene. The mcyD gene was quantified as a proxy for microcystin production through sediment cores from two lakes of western Canada. Copy numbers of both mcyD and Microcystis 16S rRNA correlated with chemical analyses of microcystin through time in cores. Cyanobacteria in the more eutrophic of these lakes shifted toward less diverse assemblages and more toxigenic taxa in recent years. Lastly, temporal and spatial changes in cyanobacterial diversity were analyzed through pyrosequencing of cyanobacterial 16S rRNA along a latitudinal transect representative of northern Canada. Significant shifts towards less diverse assemblages were found, composed of potentially toxigenic strains, suggestive of climate warming in northern latitudes. These results support recent reports of increased abundance and geographic expansion of cyanobacteria and point to increases in cyanotoxins in some cases. Using DNA archived in sediments to determine the historical state of cyanobacterial abundance and diversity could help inform lake management policies.

description: Knowledge synthesis constitutes a key part of evidence-based medicine and a scoping review is a type of knowledge synthesis that maps the breadth of literature on a topic. Conducting a scoping review is resource-intensive and, as a result, it can be challenging to maintain best practises throughout the process. Much of the current guidance describes a scoping review framework or broad ways to conduct a scoping review. However, little detailed guidance exists on how to complete each stage to optimise the process. We present five recommendations based on our experience when conducting a particularly challenging scoping review: 1) Engage the expertise of a librarian throughout the process, 2) Conduct a truly systematic search, 3) Facilitate communication and collaboration, 4) Explore new tools or repurpose old ones, and 5) Test every stage of the process. These recommendations add to the literature by providing specific and detailed advice on each stage of a scoping review. Our intent is for these recommendations to aid other teams that are undertaking knowledge synthesis projects.

Characterizing the Role of Gds1p in the Saccharomyces cerevisiae Environmental Stress Response

Stress Response

description: The transcription factors Msn2p and Msn4p are major components of the Saccharomyces cerevisiae environmental stress response. Their transient activation/deactivation is dependent on a regulatory network centering on nucleocytoplasmic shuttling but also includes a range of other mechanisms. The acetyltransferase complex, NuA4 has been implicated in repression of Msn2p yet the mechanism is largely unknown. Gds1p is an uncharacterized yeast protein identified in a recent study as a physical interactor and acetylation target of NuA4. Gds1 protein level is dependant both on NuA4 and environmental stress and our analysis shows it to be involved in the nuclear exclusion of Msn2p in the absence of stress. Unstressed cells lacking GDS1 exhibit increased nuclear accumulation Msn2p and an increase in transcription of the stress reporter gene, HSP12. My work supports a model in which Gds1 and NuA4 can work independently to inhibit the Msn2/4 dependant yeast stress response in the absence of stress.

description: Soft materials exhibit significant nonlinear geometric deformations and stress-strain relationships under external forces. This paper explores weakly nonlinear elasticity theories, including Landau's and Murnaghan's formulations, advancing understanding beyond linear elasticity. We establish connections between these methods and extend strain-energy functions to the third and fourth orders in powers of epsilon, where epsilon is defined as the square root of the inner product of H with itself, epsilon = sqrt(H * H), and epsilon is between 0 and 1. Here, H represents the perturbation to the deformation gradient tensor, where the deformation gradient F is given by F = I + H. Furthermore, we address simplified strain-energy functions applicable to incompressible materials. Through this work, we contribute to a comprehensive understanding of nonlinear elasticity and its relationship to weakly nonlinear elasticity, facilitating the study of moderate deformations in soft material behavior and its practical applications.

description: In a context that sums up the syntagm of the survey, the place of Ortigia, an historical archive of building and summation of harmonious sensory effects, should be seen as an urban aggregation without boundaries, substantially not enclosed by the skyline and open to a rapport with the sea. The methodological approach of the study undertaken tackles the issue of managing information that is highly interrelated, referring to the entire monumental unicum, by means of recognition of the parts, at times also fragmentary. The research is articulated within a coherent frame of interactive readings, the outcome of responsible working choices of surveying and graphic rendering, always verifiable and adaptable to the specific qualities of the site. In this paper, the results related to a place of particular fascination and importance, namely the Cathedral square of Ortigia, are reported.

L'approccio metodologico dello studio intrapreso affronta il tema della gestione di informazioni fortemente interrelate, riferite a tutto l’unicum monumentale, attraverso il riconoscimento delle parti anche frammentarie. La ricerca si articola in un insieme di letture interagenti, frutto di responsabili scelte operative di rilevamento e restituzione grafica, sempre verificabili e adattabili alle peculiarità del sito indagato. In questa sede si riportano i risultati relativi ad un ambito di particolare fascino e risalto, la piazza Duomo di Ortigia.

description: Pancreatic cancer, characterized by its notable prevalence and mortality rates, demands accurate lesion delineation for effective diagnosis and therapeutic interventions. The generalizability of extant methods is frequently compromised due to the pronounced variability in imaging and the heterogeneous characteristics of pancreatic lesions, which may mimic normal tissues and exhibit significant inter-patient variability. Thus, we propose a generalization framework that synergizes pixel-level classification and regression tasks, to accurately delineate lesions and improve model stability. This framework not only seeks to align segmentation contours with actual lesions but also uses regression to elucidate spatial relationships between diseased and normal tissues, thereby improving tumor localization and morphological characterization. Enhanced by the reciprocal transformation of task outputs, our approach integrates additional regression supervision within the segmentation context, bolstering the model's generalization ability from a dual-task perspective. Besides, dual self-supervised learning in feature spaces and output spaces augments the model's representational capability and stability across different imaging views. Experiments on 594 samples composed of three datasets with significant imaging differences demonstrate that our generalized pancreas segmentation results comparable to mainstream in-domain validation performance (Dice: 84.07%). More importantly, it successfully improves the results of the highly challenging cross-lesion generalized pancreatic cancer segmentation task by 9.51%. Thus, our model constitutes a resilient and efficient foundational technological support for pancreatic disease management and wider medical applications. The codes will be released at https://github.com/SJTUBME-QianLab/Dual-Task-Seg.

description: Involuted soil horizons and buried organic matter in the active layer and near-surface permafrost provide evidence that soil movement or cryoturbation is occurring within the active layer in hummocky terrain. Cryoturbation in the active layer of permafrost-affected soils could have significant implications in sequestering carbon, including trace metals and contaminants that are absorbed onto organic matter. Though several hummock development theories exist, there has thus far been limited evidence to support them; similarly, few studies have been able to establish hummock age. This study aimed to contribute radiocarbon-dated ages of buried organics in both the active layer and permafrost, as well as provide evidence for the convective cell/equilibrium model and the collapse model. Trenches were dug along a transect at two well-developed hummock sites in the Mackenzie Delta near Inuvik, NWT. Active layer and permafrost samples were analyzed for distribution of gravimetric water content (GWC), organic matter, inorganic carbon, and carbon-14 (C14). Results determined material ranged in age from the modern period (1959-1987AD) to 2300 yr BP with a generally normal distribution. Buried organics within the active layer ranged from 557-670 yr BP and 1023-1240 yr BP, with average displacement rates of 0.43 mm/yr and 0.16 mm/yr, respectively. These results suggest the convective cell/equilibrium and hummock collapse models can function simultaneously.
Novel Decentralized Node Failure Recovery Scheme in Virtualized Networks

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2013

description: The current Internet infrastructure, managed by multiple stakeholders, is unable to respond to the increasing new demands of services as it is hard to put the conflicted objectives of multiple Internet service providers together. Network virtualization has emerged as a new paradigm that overcomes the above challenge by partitioning the physical network to multiple isolated virtual networks used by different clients. Network resources failure is one of the issues that affect the network performance, which in turn impairs the service offered to the clients. This thesis addresses the problem of recovering virtual networks (VNs) affected by a substrate node failure. A novel heuristics-based algorithm that efficiently reallocates new resources to the affected VNs after a node failure is proposed. In this algorithm, a manager substrate node executes a set of recovery steps to migrate all the hosted virtual nodes in the failed substrate node in addition to the virtual paths traveling across it. The proposed approach is executed in a distributed manner without any coordination from the central infrastructure provider. The developed scheme efficiently minimizes the node failure recovery cost, the time needed to recover the virtual nodes hosted on the failed substrate node and hence significantly reduces the service interruption period. This, in turn, results in increasing the service provider revenue and decreasing the penalty charges paid for service level agreement violation. Performance results demonstrate the significant reduction in VN service cost and interruption time.

description: Ancient basin-floor strata are exceptionally well exposed in the Neoproterozoic Windermere Supergroup in the southern Canadian Cordillera. Data from the Castle Creek outcrop, where strata of the upper Kaza Group crop out, and the Mt. Quanstrom outcrop, where the middle Kaza is exposed, form the main dataset for this study. The aim of this study is to describe and interpret the strata starting at the bed scale, followed by stratal element scale, lobe scale and ultimately fan scale. Strata of the Kaza Group comprise six sedimentary facies representing deposition from a variety of fluid and cohesive sediment gravity flows. These, in turn, populate seven stratal elements that are defined by their basal contact, cross-sectional geometry and internal facies distribution. The lithological characteristics of stratal elements vary little from proximal to more distal settings, but their relative abundance and stacking pattern do, which, then, forms the basis for modeling the internal architecture of lobes. Lobes typically comprise an assemblage of stratal elements, which then are systematically and predictably arranged in both space (along a single depositional transect) and time (stratigraphically upward). Lobes typically became initiated by channel avulsion. In the proximal part of the system scours up to several meters deep, several tens of meters wide are interpreted to have formed by erosion downflow of the avulsion node. Erosion also charged the flow with fine-grained sediment and on the lateral margins and downflow avulsion splays were deposited. Later flows then exploited the basin-floor topography and on the proximal basin-floor carved a feeder channel, which then fed a downflow depositional lobe. At the mouths of feeder channels flows became dispersed through a network of distributary channels that further downflow shallow and widen until eventually merging laterally in sandstone-rich terminal splays. During the lifespan of a single lobe the feeder channel remains fixed, but the distributary channel network and its associated terminal splays wander, causing them to stack and be intercalated laterally and vertically. Eventually an upstream avulsion terminates local sediment supply, causing a new lobe to be initiated elsewhere on the fan, and the process repeats.

description: The objectives of this thesis were to synthesize existing RCT evidence and post-market observational evidence of TNF-α inhibitors in IBD. Two separate systematic reviews were performed: an overview of systematic reviews of RCTs, and a systematic review of post-market observational studies of TNF-α inhibitors in Crohn’s disease and ulcerative colitis. The overview of systematic reviews included 37 studies. RCT evidence demonstrated superiority of all agents to placebo in Crohn’s disease and ulcerative colitis, with no increased risk of malignancy or serious adverse events. Network meta-analyses have not shown superiority of any agent compared to another. The second systematic review included 255 studies. Included studies were deemed to be unamenable to pooling with substantial methodological and clinical diversity. Available evidence is insufficient to determine whether real-world effectiveness and safety is consistent with RCTs, but suggests no increased risk of malignancy and no difference in efficacy between adalimumab and infliximab.

description: In this thesis, robot navigation using the Particle Filter based FastSLAM approach for obstacle avoidance derived from a modified Velocity Potential Field method was investigated. A switching controller was developed to deal with robot’s efficient turning direction when close to obstacles. The determination of the efficient turning direction is based on the local map robot derived from its on board local sensing. The estimation of local map and robot path was implemented using the FastSLAM approach. A particle filter was utilized to obtain estimated robot path and obstacles (local map). When robot sensed only obstacles, the estimated robot positions was regarding to obstacles based the measurement of the distance between the robot and obstacles. When the robot detected the goal, estimation of robot path will switch to estimation with regard to the goal in order to obtain better estimated robot positions. Both simulation and experimental results illustrated that estimation with regard to the goal performs better than estimation regarding only to obstacles, because when robot travelled close to the goal, the residual error between estimated robot path and the ideal robot path becomes monotonously decreasing. When robot reached the goal, the estimated robot position and the ideal robot position converge. We investigated our proposed approach in two typical robot navigation scenarios. Simulations were accomplished using MATLAB, and experiments were conducted with the help of both MATLAB and LabVIEW. In simulations and experiments, the robot successfully chose efficiently turning direction to avoid obstacles and finally reached the goal.
The emergence of an organic food market in Australia: an economic sociological approach
Creators: name: Glezos, Lee
Publisher: name: Swinburne
Year: 2024

description: Drawing on economic sociology, this thesis provides the first major exploration of how the market in Australian organic food initially emerged from the early 1980s. The research tracks several key organisational projects, that were primarily driven by the sustainable agriculture movement, and geared toward transforming mainstream food production away from the conventional chemical-based model. The findings suggest that these projects gained enough legitimacy with key stakeholders – such as state departments, farmers and consumers – to establish an alternative market niche, but the broader project of mainstream acceptance was significantly limited. In large part this was due to a countermobalisation from a coalition of entrenched market players with interests in continuing conventional agriculture. Actors such as the chemical industry deployed extensive resources to reaffirm the status quo, albeit one that accommodated organic food as a marginal member.

Geoadditive Quantile Regression Model for Sewer Pipes Deterioration Using Boosting Optimization Algorithm
Creators: name: Balekelayi, Ngandu

Publisher: name: Multidisciplinary Digital Publishing Institute
Year: 2020

description: Proactive management of wastewater pipes requires the development of deterioration models that support maintenance and inspection prioritization. The complexity and the lack of understanding of the deterioration process make this task difficult. A semiparametric Bayesian geoadditive quantile regression approach is applied to estimate the deterioration of wastewater pipe from a set of covariates that are allowed to affect linearly and nonlinearly the response variable. Categorical covariates only affect linearly the response variable. In addition, geospatial information embedding the unknown and unobserved influential covariates is introduced as a surrogate covariate that capture global autocorrelations and local heterogeneities. Boosting optimization algorithm is formulated for variable selection and parameter estimation in the model. Three geoadditive quantile regression models (5%, 50% and 95%) are developed to evaluate the band of uncertainty in the prediction of the pipes scores. The proposed model is applied to the wastewater system of the city of Calgary. The results show that an optimal selection of covariates coupled with appropriate representation of the dependence between the covariates and the response increases the accuracy in the estimation of the uncertainty band of the response variable. The proposed modeling approach is useful for the prioritization of inspections and provides knowledge for future installations. In addition, decision makers will be informed of the probability of occurrence of extreme deterioration events when the identified causal factors, in the 5% and 95% quantiles, are observed on the field.

description: β-Aminocarbonyl motifs are a privileged substructures in medicinal chemistry and peptidomimetics. As part of our efforts toward metal free aminations, we developed a method for intermolecular amino-carbonylation of alkenes using hydrazones. This method provides access to cyclic azomethine imines containing a β-aminocarbonyl motif. Conceptually, these dipoles can be derivatized into many bioactive compounds, such as 1,3-diamines, β-amino amides and β-amino acids. The first part of this thesis will present the results on the derivatization of our aminocarbonylation products into various nitrogen-containing molecules, such as β-amino amides, β-amino acids and pyrazolones. More specifically, a short, chromatography-free derivatization of azomethine imines into N-Boc-β-amino amides will be presented. Following these results, the next chapter will focus on attempts at develop novel aminocarbonylation reactivity between 1,2-diacylhydrazines and alkenes followed by results from our reductive N-N bond cleavage experiments on our cyclic hydrazides.

description: This dissertation explores the ways in which the everyday (in)securities of people in southwestern Ukraine can illuminate our understanding of contemporary political life. Rather than using traditional units of analysis or given categories—the state, the individual, identity—the dissertation focuses on relations between people in and connected to a single village to develop a novel framework for analyzing politics and the political. The dissertation opens with an interrogation of the practical and theoretical challenges associated with current conceptualizations of security; our understanding of the political; and the role of ethnography in theorization and presents a research design meant to address those challenges. Drawing upon extensive participant-observation and other immersion-based research in a post-Soviet borderland wedged between Ukraine and Slovakia, and using an analytical tool I call “togetherness,” the thesis presents an ethnographic account of social interactions, economy, and authority in this largely Hungarian-speaking rural area. The third part of the dissertation applies the idea of an ontological shift and draws on complex systems and structuration theory (Luhmann and Giddens, respectively) to rethink the ethnographic analysis and to highlight relationships between structural and existential realms of political life. Here, the concept of security becomes central to the theorization, and the overall argument illuminates the intimate relationship between the idea of security and the political. Ultimately, this approach allows us to expand the scope of political ethnography: theorizing beyond thick description; integrating broader perspectives without losing the texture of the local; and developing an approach to research that can be replicated in other settings.
