The experience of enabling aspects that facilitate help-seeking behaviours among British South Asian individual’s reporting depression and low mood: An IPA study.
Creators: name: Jaspal, Priya
Publisher: name: University of Surrey
Year: 2020

description: Help-seeking behaviours under a cultural context and the role of meaning-making in relation to the field of Counselling Psychology have been of academic interest over the last 30 years. This study explores British South Asian (BSA) individual’s experience of enabling help-seeking behaviours when living with depression and low mood. The aim of this study is to illuminate the meanings and values of contextualising help-seeking behaviours in relation to depression and low mood in a bi-cultural context. Semi-structured interviews were conducted with Six BSA individuals using Interpretative Phenomenological Analysis (IPA). Four super-ordinate themes emerged from the data. The findings highlight the tension between participant’s painful experiences of low mood/depression in their cultural context, and how some of their internalisation processes play a role in their help-seeking behaviours.
An Assessment of Women's Abortion Experiences in Istanbul, Turkey
Creators: name: MacFarlane, Katrina
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2016
Subjects: Turkey, abortion, reproductive health

description: Abortion upon request has been legal in Turkey since 1983. In 2012 the Prime Minister of Turkey announced his intent to restrict or ban abortion. The public protested in response and the Turkish government did not amend the abortion law. However, recent anecdotal evidence suggests that the provision of abortion in public hospitals has diminished significantly. The purpose of this qualitative study was to explore women’s experiences obtaining abortion care in Istanbul, Turkey. We also documented key informants’ perspectives about abortion and reproductive health service availability in Istanbul. According to women and key informants, abortion availability has decreased remarkably and is now only available in one public hospital in Istanbul. Abortion care remains available in the private sector but there are nonetheless barriers to obtaining timely abortion care in Turkey. To improve abortion services, future efforts should focus on re-integrating abortion services in the public sector and making medication abortion available to Turkish women.

description: The increasing demand for spectrum resources due to the rapid growth of broadband wireless services, commercialisation of 5G, and development of 6G communication techniques have highlighted the importance of addressing spectrum scarcity and underutilisation. Dynamic Spectrum Access and Cognitive Radio technology, supported by Compressed Sensing, offer promising approaches to improve radio spectrum utilisation and wireless communication efficiency.

description:

description: This PhD thesis investigates various aspects of Compressed Spectrum Sensing (CSS) systems to address existing challenges and enhance practical implementation. The research contributes to some of the key techniques that enhance the performance of CSS systems in a practical framework, including refining spectrum recovery accuracy, optimising sampling pattern design, and improving reconstruction algorithms.

description:

description: Key contributions include the development of a block Multiple Measurement Vectors (MMV) model to enhance spectrum support set reconstruction accuracy, addressing the limitations of traditional MMV models. The research also explores the design of sampling patterns for multicoset sampling in noisy environments and proposes two optimisation algorithms to minimise mutual coherence, improving spectrum recovery performance. Furthermore, a double-threshold matching pursuit algorithm is introduced to reduce high false-alarm rates in signal reconstruction.

description:

description: A significant aspect of this thesis is the emphasis on system implementation. The research presents a software-defined system for CSS on mmWave to accelerate prototype validation and hardware design parameter selection. This system achieves real-time spectrum sensing for a 3.072 GHz bandwidth signal at a 28.5 GHz centre frequency, utilising Bayesian sparsity estimation and data decimation algorithms for robust performance.

description:

description: Finally, the thesis includes the design and implementation of a multicoset sampler for wideband spectrum sensing, the first on-board realisation of a periodic nonuniform sampling structure. This achievement demonstrates the practical application of the proposed techniques and advancements in CSS system development.

description: The COVID-19 pandemic and related public health efforts limiting in-person social interactions present unique challenges to adolescents. Social media, which is widely used by adolescents, presents an opportunity to counteract these challenges and promote adolescent health and public health activism. However, public health organizations and officials underuse social media to communicate with adolescents. Using well-established risk communication strategies and insights from adolescent development and human-computer interaction literature, we identify current efforts and gaps, and propose recommendations to advance the use of social media risk communication for adolescents during the COVID-19 pandemic and future disasters.

description: The peri-coital contraceptive pill is a potential method for pregnancy prevention that could be taken in a period before or after unprotected sexual intercourse. However, uptake of a new contraceptive method relies on accessible terminology and frameworks with which to discuss it. I conducted seven focus group discussions across Canada to understand how women talk about different reproductive health technologies, explore the ways these discourses influence language and frameworks women use to talk about peri-coital contraceptives, and identify perceptions of and concerns about this potential method. Women thought the peri-coital contraceptive pill would be a valuable addition to current contraception. They disliked the name ”peri-coital”; although some participants created more resonant names related to unique aspects of this method, many found it challenging to clearly discuss the method with existing language for contraception. Concerted effort to develop terminology that is clearer may help facilitate the eventual introduction of this new contraceptive method in Canada and beyond.

description: La place de plus en plus prépondérante qui occupe la défense des droits humains dans les organisations paysannes en Colombie est sans doute une transformation très importante. La présente recherche analyse les dynamiques qui ont amenées les organisations paysannes à s’engager dans cette voie et étudie les conséquences qui en découlent. Deux dynamiques ont retenu notre attention dans le but de comprendre pourquoi la défense des droits humains devient si importante au sein des organisations paysannes depuis le milieu des années 1980. D’un côté, la recrudescence de la répression et, d’un autre côté, la reconnaissance croissante des droits. En effet, à partir des années 1980, les relations sociales d’appropriation et de domination se caractérisent par le contrôle paramilitaire imposé à sang et feu; alors que sous l’auspice international une série des politiques néolibérales favorables au discours des droits sont mises de l’avant. Pour les organisations paysannes, ces deux dynamiques paradoxales se transforment en opportunité politique propice au déclenchement de mobilisations et d’organisation. Cette opportunité politique s’articule autour de la défense des droits humains. Pour les organisations paysannes, la défense des droits humains entraîne des effets paradoxaux qui vont de la radicalisation à l’institutionnalisation, tout en reléguant d’autres revendications parce que moins urgentes que la défense de la vie. Par ses caractéristiques, la dynamique de la lutte paysanne depuis les années 1990 correspondent à une lutte de résistance. La résistance, qui est initialement pour la défense de la vie, prend des routes différentes selon les communautés parviennent à rester sur le territoire ou contrairement sont obligées au déplacement. Les communautés qui restent sur le territoire, lient la défense des droits humains à la défense du territoire et ce faisant imprègnent la défense des droits d’une interprétation nouvelle axée sur la justice sociale et judiciaire. Les communautés déplacées et leurs organisations, doublement fragilisées, sont cantonnées à une dynamique défensive qui est très peu en continuité avec les luttes pour la terre et pour la construction d’une économie paysanne qu’elles menaient avant la recrudescence de la répression et la consécutive défense des droits humains.

“We Educate, they Indoctrinate” Religion and the Politics of Togetherness in Ontario Public Education

description: Religion has had an ambiguous role in Ontario public education, having provided both the common language for social cohesion and for resistance by religious groups to what they have perceived to be a dominant, exclusive and coercive ethos. In similar ways, religious freedom and diversity have been highly prized and protected in Ontario while at the same time being sources of anxiety and social disruption. Using critical discourse analysis and critical genealogical analysis I examine the conflicted role of religion in Ontario public education through competing discourses in political rhetoric, selected government documents formulating ways of conceptualizing the role of religion in public education from 1950 to 2003 and case law between 1985 and 1997. More precisely, I examine ways in which educational, social and political goals of education have been intertwined throughout the history of Ontario public education. I show that the public school system has been a state instrument privileged to deliver public education as a way to resolve the tension between social cohesion and social diversity by delivering common civic values. One result is that challenges to the public school system are often interpreted as attacks on public education and on Ontario society, particularly when those challenges are launched by religious groups. This has meant that debates about the role of religion in public education tend to be volatile making serious dialogue about this important social issue difficult to achieve while restricting the space for religious diversity in public education.

description: Nel volume qui recensito George Steiner si interroga sulla legittimità della trasmissione della tradizione filosofica e letteraria occidentale. L’indagine si concentra sul ruolo che la cultura ha svolto nell’evoluzione umana dalla Rivoluzione francese ai giorni nostri, esaminando tanto l’insopprimibile tendenza alla barbarie dell’uomo occidentale quanto la sua costante volontà di ricerca e di sviluppo intellettuale. Gli interrogativi posti sul compito che la cultura dovrebbe assolvere dopo le tragedie della prima metà del novecento – in particolare quella dell’Olocausto – sono, in questo senso, quanto mai attuali e pressanti.

description: To arrive at some viable product design, product development processes frequently use numerical simulations and mathematical programming techniques. Topology optimization, in particular, is one of the most promising techniques for generating insightful design choices. Topology optimization problems reduce to an NP-hard combinatorial optimization problem, where the combination of the existence or absence of the material at some positions is optimized. In this study, we examine the usage of quantum computers as a potential solution to topology optimization problems. The proposed method consists of two variational quantum algorithms (VQAs): the first solves the state equilibrium equation for all conceivable material configurations, while the second amplifies the likelihood of an optimal configuration in quantum superposition using the first VQA's quantum state. Several experiments, including a real device experiment, show that the proposed method successfully obtained the optimal configurations. These findings suggest that quantum computers could be a potential tool for solving topology optimization problems and they open the window to the near-future product designs.

Effects of (raised intracellular Ca2+ by) ATXII on circadian rhythmicity of BMAL1 expression, phosphorylation and cellular localisation: role of calcineurin
Creators: name: Siakalli, Andria
Publisher: name: University of Surrey
Year: 2020

description: Atrial fibrillation (AF) cardiac arrhythmia is associated with [Ca2+]i overload contributing in disturbed action potential prolongation, and in alteration of gap junctional connexin protein expression and phosphorylation status. Episodes of AF are more frequent during daytime, suggesting a possible involvement of circadian rhythms (and the clock genes driving it, in particular Bmal1) contributing to its occurrence. Also, Bmal1 reported to directly regulate Ca2+ and Na+ ionic currents, as well as, Ca2+-related release channels, however, the relationship between AF-mediated pathways, Bmal1 clock gene expression and circadian rhythmicity is far from clear. This study aimed to explore the involvement of Bmal1 in driving the AF occurrence via changes in Ca2+ homeostasis through sustained activation of NaP channels and/or alteration in connexin expression and phosphorylation status by Ca2+-dependent protein phosphatase calcineurin (CaN). HL-1 clone 6 (HL1-6) cells were used as an in vitro model and synchronised with 50 % fetal bovine serum for the interpretation of circadian characteristics. HL1-6 cells were treated with anemonia sulcata toxin II (ATXII; 1 nM) in presence and/or absence of Ranolazine (10 µM), BAPTA-AM (5 µM) or CAIP (25 µM). Bmal1 gene circadian rhythmicity was observed under control conditions (26.09±0.78 hrs). Such pattern was highly disturbed under raised [Ca2+]i by ATXII (17.05±1.07 hrs) and was restored in presence of Ranolazine (25.32±0.97 hrs) and BAPTA-AM (25.91±0.54 hrs). This suggests that Ca2+ mediated changes in the cellular circadian clock are an integral part of the aetiology of atrial arrhythmia’s, and that the NaP/raised Ca2+ arrhythmogenic pathway directly affects Bmal1 circadian expression in atria; hence strengthens its association with AF occurrence. BMAL1 oscillatory protein expression observed under ATXII treatment was similarly reversed in presence of Ranolazine, proposing the involvement of Nav1.5. channel subtype driving such mechanisms. BMAL1 protein expression was also affected by CAIP (in presence of ATXII), suggesting a possible action of CaN on Ser42 residue. Interestingly, the pCx43-Ser368 show a similar protein expression pattern as BMAL1, proposing an immediate association of circadian mechanisms driving Cx43 (but not Cx40) expression in AF occurrence. Finally, the phosphorylated Cx43-Ser368 protein expression levels and oscillatory pattern were restored in presence of CAIP, proposing CaN involvement in mediating the ATXII-effects under AF occurrence. This further implies that the Ca2+/CaN signalling pathway is driving BMAL1 protein expression and localisation in atria.

description: We obtain detailed analytic formulas for the density and probability distribution of the waiting time in a time-division multiple-access (TDMA) model with a finite buffer and state-dependent service. On successive intervals of length equal to the duration of a slot, the density is expressed as a linear combination of beta densities with positive coefficients. A recursive scheme, obtained by a matrix-analytic derivation, allows for the highly efficient computations of the coefficient sequences. An expression for the mean waiting time is derived using the classical queueing formula L=λW. We also demonstrate that our methodology provides a concise treatment of various special cases that have been studied over the past half century.

description: Advancement in mid-infrared (MIR) technology has led to promising biomedical applications of MIR spectroscopy, such as liquid biopsy or breath diagnosis. On the contrary, MIR microscopy has been rarely used for live biological samples in an aqueous environment due to the lack of spatial resolution and the large water absorption background. Recently, mid-infrared photothermal (MIP) imaging has proven to be applicable to 2D and 3D single-cell imaging with high spatial resolution inherited from visible light. However, the maximum measurement rate has been limited to several frames/s, limiting its range of use. Here, we develop a significantly-improved wide-field MIP quantitative phase microscope with two orders-of-magnitude higher signal-to-noise ratio than previous MIP imaging techniques and demonstrate single-live-cell imaging beyond video rate. We first derive optimal system design by numerically simulating thermal conduction following the photothermal effect. Then, we develop the designed system with a homemade nanosecond MIR optical parametric oscillator and a high full-well-capacity image sensor. Our high-speed and high-spatial-resolution MIR microscope has great potential to become a new tool for life science, in particular for single-live-cell analysis.
The role of depressive symptoms and cardiometabolic risk factors in the prediction of dementia: a cross-country comparison in England, the United States and China
Creators: name: Kontari, Panagiota
Publisher: name: University of Surrey
Year: 2024

description: Background: Dementia is a significant public health concern, with up to 40% of cases potentially preventable through risk factor modification. Depression and cardiometabolic conditions are suggested as modifiable risk factors for dementia, but their relationship to dementia risk remains unclear.

description: Aim: This thesis investigated the role of depressive symptoms and cardiometabolic risk factors, including central obesity, low HDL cholesterol, systolic and diastolic blood pressure (BP), hyperglycaemia, diabetes, and increased inflammation, in the risk of dementia among older individuals in England, the US, and China.

description: Methods: Data were drawn from the English Longitudinal Study of Ageing, the Health and Retirement Study, and the China Health and Retirement Longitudinal Study. The analyses included 7,666 participants from ELSA (waves 2–9, 2004/05–2018/19), 6,735 from HRS (waves 8–14, 2006/07–2018/19), and 11,847 from CHARLS (waves 1–4, 2011/12–2018/19), aged 50 years or older at baseline.

description: Results: Depressive symptoms emerged as an independent risk factor for dementia, regardless of the presence of cardiometabolic factors, with individuals exhibiting increasing and chronically high depressive symptoms facing the highest risk across all three populations. Elevated systolic BP consistently demonstrated a significant association with dementia in all three countries. However, diabetes, hyperglycaemia, low HDL cholesterol, and increased inflammation showed country-specific associations with dementia risk. Through latent class analysis, distinct patterns of combined cardiometabolic risk factors, including a complex cardiometabolic cluster in Western countries and an obesity-hypertension cluster in China, showed an increased dementia risk. Cardiometabolic risk appeared to precede depressive symptoms and dementia development, with depression serving as a potential pathway linking cardiometabolic health to dementia.

description: Conclusion: This research provides evidence concerning the causal and temporal associations between depressive symptoms, cardiometabolic risk factors and dementia development. Culturally-sensitive interventions for the early identification and treatment of depressive symptoms and cardiometabolic comorbidities suggest a promising approach to addressing the growing burden of dementia in Western and non-Western countries.

description: This thesis deals with the design of cost-effective large-scale RFID networks from both software and hardware aspects. To start with, different computer-aided tools were developed to maximize performance. The first set of algorithms focused on the elimination of redundant readers to minimize the cost and interference in large-scale RFID networks. For validation, uniform reader coverage was assumed, as widely used in most available publications. Then, both omni-directional and directional commercial reader antenna data were included for more reliability. Besides redundancy, an efficient physical placement of readers was also investigated by considering both uniform and random distribution over space. For this purpose, genetic-based algorithms have been proposed to increase reader coverage using commercial reader antenna beams. Energy consumption is also a critical design parameter for dense RFID networks. Therefore, a third set of algorithms was developed to efficiently minimize the energy consumption of large-scale RFID systems. Note that all above optimization techniques were achieved without compromising the whole RFID network performance. To further optimize cost and performance of large-scale RFID networks, a hardware approach through reader antenna design has been considered. In fact, since different RFID frequency bands have been assigned worldwide, large-scale RFID networks implemented in industrial parks, airports, or international trade zones, may deal with imported merchandise using tags operating at different frequencies. Therefore, in-house single and dual-band microstrip and CPW fed monopole antennas were successfully designed and tested to improve system adaptability to various RFID standards. These antennas were designed using both electromagnetic commercial simulators (HFSS) and in-house FDTD-based techniques. Finally, to further extend dense RFID network capabilities, one may implement a substantial number of readers and antennas with small reading ranges to cover a large monitoring area, or use high gain phased array antenna system for an extended reading range of an RFID reader for a smaller number of total reader deployments. Therefore, a phased antenna array system can be an efficient alternative for dense RFID networks. Thus, a switched beam network to control the phase of the radiating elements of the array has been successfully designed and tested.

description: Due to its appearance in a remarkably wide field of applications, such as audio processing and coherent diffraction imaging, the short-time Fourier transform (STFT) phase retrieval problem has seen a great deal of attention in recent years. A central problem in STFT phase retrieval concerns the question for which window functions $g \in L^2(\mathbb{R}^d)$ and which sampling sets $Λ\subseteq \mathbb{R}^{2d}$ is every $f \in L^2(\mathbb{R}^d)$ uniquely determined (up to a global phase factor) by phaseless samples of the form $$ |V_gf(Λ)| = \left \{ |V_gf(λ)| : λ\in Λ\right \}, $$ where $V_gf$ denotes the short-time Fourier transform (STFT) of $f$ with respect to $g$. The investigation of this question constitutes a key step towards making the problem computationally tractable. However, it deviates from ordinary sampling tasks in a fundamental and subtle manner: recent results demonstrate that uniqueness is unachievable if $Λ$ is a lattice, i.e $Λ= A\mathbb{Z}^{2d}, A \in \mathrm{GL}(2d,\mathbb{R})$. Driven by this discretization barrier, the present article centers around the initiation of a novel sampling scheme which allows for unique recovery of any square-integrable function via phaseless STFT-sampling. Specifically, we show that square-root lattices, i.e., sets of the form $$ Λ= A \left ( \sqrt{\mathbb{Z}} \right )^{2d}, \ \sqrt{\mathbb{Z}} = \{ \pm \sqrt{n} : n \in \mathbb{N}_0 \}, $$ guarantee uniqueness of the STFT phase retrieval problem. The result holds for a large class of window functions, including Gaussians.

description: High-speed measurement confronts the extreme speed limit when the signal becomes comparable to the noise level. In the context of broadband mid-infrared spectroscopy, state-of-the-art ultrafast Fourier-transform infrared spectrometers, in particular dual-comb spectrometers, have improved the measurement rate up to a few Mspectra/s, which is limited by the signal-to-noise ratio. Time-stretch infrared spectroscopy, an emerging ultrafast frequency-swept mid-infrared spectroscopy technique, has shown a record-high rate of 80 Mspectra/s with an intrinsically higher signal-to-noise ratio than Fourier-transform spectroscopy by more than the square-root of the number of spectral elements. However, it can measure no more than ~30 spectral elements with a low resolution of several cm-1. Here, we significantly increase the measurable number of spectral elements to more than 1,000 by incorporating a nonlinear upconversion process. The one-to-one mapping of a broadband spectrum from the mid-infrared to the near-infrared telecommunication region enables low-loss time-stretching with a single-mode optical fiber and low-noise signal detection with a high-bandwidth photoreceiver. We demonstrate high-resolution mid-infrared spectroscopy of gas-phase methane molecules with a high resolution of 0.017 cm-1. This unprecedentedly high-speed vibrational spectroscopy technique would satisfy various unmet needs in experimental molecular science, e.g., measuring ultrafast dynamics of irreversible phenomena, statistically analyzing a large amount of heterogeneous spectral data, or taking broadband hyperspectral images at a high frame rate.

description: For a connected graph $G$, we present the concept of a new graph matrix related to its distance and Seidel matrix, called distance Seidel matrix $\mathcal{D}^S(G)$. Suppose that the eigenvalues of $\mathcal{D}^S(G)$ be $\partial_{1}^{S}(G) \geq \cdots \geq \partial_{n}^{S}(G).$ In this article, we establish a relationship between distance Seidel eigenvalues of a graph with its distance and adjacency eigenvalues. We characterize all the connected graphs with $\partial_{1}^{S}(G)= 3.$ Also, we determine different bounds for the distance Seidel spectral radius and distance Seidel energy. We study the distance Seidel energy change of the complete bipartite graph due to the deletion of an edge. Moreover, we obtain the distance Seidel spectra of different graph operations such as join, cartesian product, lexicographic product, and unary operations like the double graph and extended double cover graph. We give various families of distance Seidel cospectral and distance Seidel integral graphs as an application.
Mentalizing in first-episode psychosis : correlates with symptomatology and traits of borderline personality disorder.

Publisher: name: University of Surrey
Year: 2020

description: Background: Comorbid borderline personality disorder (BPD) in psychosis is poorly understood, despite research suggesting that it contributes to poorer outcomes at 5 and 10-year follow-up. Mentalizing (the ability to attribute thoughts and feelings to self and others) is thought to be a transdiagnostic factor that contributes to core impairments in BPD and symptoms of psychosis. This study aimed to explore the relationship between mentalizing, positive and negative symptoms of psychosis, and traits of borderline personality disorder, in a sample of patients with first-episode psychosis, and in a non-clinical sample. Method: 32 adults with first-episode psychosis (FEP) and 149 non-clinical participants were assessed using the reflective functioning questionnaire (RFQ). The RFQ measures two dimensions of mentalizing, certainty (RFQc) and uncertainty (RFQu) about mental states. Traits of BPD and symptoms of psychosis were measured using the self-report version of the Zanarini rating scale for BPD, the Community Assessment of Psychic Experiences (CAPE), and the Green et al, paranoid thought scale. Results: Patients with FEP were significantly more impaired on the RFQ compared to the non-clinical sample, showing significantly lower certainty, and higher uncertainty about mental states. Regression analysis showed significant associations between higher scores on the RFQu and negative symptoms of psychosis in both groups. Significant associations were also found between higher RFQu and increasing BPD traits in the non-clinical sample. Conclusions: The present research provides evidence that impairments in mentalizing may be a core component of the process underlying negative symptoms of psychosis across both clinical and non-clinical samples. Mentalizing impairments may also be associated with BPD traits, but this finding was only confirmed in the non-clinical sample. Mentalizing should therefore be considered in the early assessment and treatment of patients experiencing these difficulties.

description: Campylobacter jejuni is one of the most frequent causes of gastroenteritis in both the developing and the developed world. Understanding C. jejuni biology is paramount to reducing the amount of Campylobacter jejuni in the food chain, however our understanding of the regulatory networks that enable Campylobacter jejuni to successfully colonize various hosts remains incomplete. Campylobacter jejuni has an absolute requirement for iron in order to grow as iron catalyzes a wide range of essential biochemical reactions. In contrast to many Gram negative bacteria, the genome of Campylobacter jejuni contains two iron activated Fur-family transcriptional regulators, Fur and PerR, which are primarily responsible for regulating iron homeostasis and oxidative stress respectively. We have used an integrated approach that combines genome wide technologies (ChIP-chip, RNA-seq) and structural studies to define the role of iron, Fur and PerR in Campylobacter jejuni. These studies have demonstrated that apo-Fur directly regulates gene transcription in Campylobacter jejuni, identified novel ncRNAs that are Fur and/or iron responsive, and revealed that the Fur and PerR regulons are more extensive than previously characterized. These results provide further insight into the surprisingly complex regulatory networks that allow Campylobacter jejuni to be a successful gut pathogen.

description: Background: Ginkgo (Ginkgo biloba L.) is an excellent landscape species. Its yellow-green leaf mutants are ideal materials for research on pigment synthesis, but the regulatory mechanism of leaf coloration in these ginkgo mutants remains unclear. Results: We compared the metabolomes and transcriptomes of green and mutant yellow leaves of ginkgo over the same period in this study. The results showed that the chlorophyll content of normal green leaves was significantly higher than that of mutant yellow leaves of ginkgo. We obtained 931.52M clean reads from different color leaves of ginkgo. A total of 283 substances in the metabolic profiles were finally detected, including 50 significantly differentially expressed metabolites (DEMs). We identified these DEMs and 1361 differentially expressed genes (DEGs), with 37, 4, 3 and 13 DEGs involved in the photosynthesis, chlorophyll, carotenoid, and flavonoid biosynthesis pathways, respectively. Moreover, integrative analysis of the metabolomes and transcriptomes revealed that the flavonoid pathway contained the upregulated DEM (−)-epicatechin. Fourteen DEGs from the photosynthesis pathway were positively or negatively correlated with the DEMs. Conclusions: Our findings suggest a complex metabolic network in mutant yellow leaves. This study will provide a basis for studies of leaf color variation and regulation.

description: Long wait times are a global issue in the healthcare sector, particularly in Canada. Despite numerous research findings on wait time management, the issue persists. This is partly because for a given hospital, the data required to conduct wait times analysis is currently scattered across various information systems. Moreover, such data is usually not accurate (because of possible human errors), imprecise and late. The whole situation contributes to the current state of wait times. This thesis proposes a location-aware business process management system for real-time care process monitoring. More precisely, the system enables an improved visibility of process execution by gathering, as processes execute, accurate and granular process information including wait time measurements. The major contributions of this thesis include an architecture for the system, a prototype taking advantages of commercial real-time location system combined with a business process management system to accurately measure wait times, as well as a case study based on a real cardiology process from an Ontario hospital.

description: Die Bewertung des ökologischen Zustands von Oberflächengewässern ist heute europaweit akzeptiert und in nationalen und internationalen Gesetzen festgeschrieben. Für Grundwässer und Aquifere gibt es einen derartigen Ansatz bis dato nicht. Ziel dieses Forschungsprojekts war es, ein erstes Konzept eines ökologisch orientierten Bewertungssystems für Grundwasserökosysteme zu entwerfen. Als wesentliche Schritte wurden (1) die Auswahl geeigneter Messgrößen, (2) die Inventur an ausgewählten Standorten, (3) die Suche nach einer ökologisch sinnvollen räumlichen Gliederung, (4) die Ableitung von natürlichen Hintergrundwerten und Referenzbedingungen, (5) die Identifizierung von ökologischen Kriterien und Indikatoren, und (6) ein erstes Bewertungsschema vorgeschlagen und durchgeführt. Im Rahmen des Projekts wurden Grundwässer aus über 100 Messstellen mehrfach untersucht.
La metafora e i neuroni: stato dell’arte

description: La metafora costituisce un dispositivo cognitivamente complesso, basato sulla mappatura di due domini in conflitto, che si impone in tutte le dimensioni della vita quotidiana. La prospettiva neuroscientifica consente oggi di riconoscere nel pensiero metaforico non solo un attivatore della plasticità del cervello, e in quanto tale partecipe attivo della storia evolutiva della mente umana, ma un grado successivo di elaborazione cognitiva rispetto alle mappature implicite nella metonimia.

description: We consider the problem of testing whether a single coefficient is equal to zero in linear models when the dimension of covariates $p$ can be up to a constant fraction of sample size $n$. In this regime, an important topic is to propose tests with finite-sample valid size control without requiring the noise to follow strong distributional assumptions. In this paper, we propose a new method, called residual permutation test (RPT), which is constructed by projecting the regression residuals onto the space orthogonal to the union of the column spaces of the original and permuted design matrices. RPT can be proved to achieve finite-population size validity under fixed design with just exchangeable noises, whenever $p < n / 2$. Moreover, RPT is shown to be asymptotically powerful for heavy tailed noises with bounded $(1+t)$-th order moment when the true coefficient is at least of order $n^{-t/(1+t)}$ for $t \in [0,1]$. We further proved that this signal size requirement is essentially rate-optimal in the minimax sense. Numerical studies confirm that RPT performs well in a wide range of simulation settings with normal and heavy-tailed noise distributions.
Optimization of CT images for breast cancer screening using spectral imaging.

description: About 1.7 million new cases of breast cancer were estimated by the World Health Organization (WHO) in 2012, accounting for 23 percent of all female cancers. In the UK 33 percent of women aged 50 and above were diagnosed in the same year, thus positioning the UK as the 6th highest in breast cancer amongst the European countries. The national Screening programme in the UK has been focused on the procedure of early detection and to improve prognosis by timely intervention to extend the life span of patients. To this end, the National Health Service Breast Screening Programme (NHSBSP) employs 2-D planar mammography because it is considered to be the gold standard technique for early breast cancer detection worldwide. Breast tomosynthesis has shown great promise as an alternative method for removing the intrinsic overlying clutter seen in conventional 2D imaging. However, preliminary work in breast CT has provided a number of compelling aspects that motivates the work featured in this thesis. These advantages include removal of the need to mechanically compress the breast which is a source of screening non-attendances, and that it provides unique cross sectional images that removes almost all the overlying clutter seen in 2D. This renders lesions more visible and hence aids in early detection of malignancy. However work in Breast CT to date has been focused on using scaled down versions of standard clinical CT systems. By contrast, this thesis proposes using a photon counting approach. The work of this thesis focuses on investigating photoncounting detector technology and comparing it to conventional CT in terms of contrast visualization. Results presented from simulation work developed in this thesis has demonstrated the ability of photoncounting detector technology to utilize data in polychromatic beam where contrast are seen to decrease with increasing photon energy and compared to the conventional CT approach which is the standard clinical CT system.
