Enhancements in Electrical Impedance Tomography (EIT) image reconstruction for three-dimensional lung imaging
Creators: name: Graham, Bradley Michael
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2007
Subjects: subject: Engineering, Electronics and Electrical.

description: Electrical Impedance Tomography (EIT) is an imaging technique which calculates the electrical conductivity distribution within a medium from electrical measurements made at a series of electrodes on the medium surface. Reconstruction of conductivity or conductivity change images requires the solution of an ill-conditioned nonlinear inverse problem from noisy data. EIT is a hard problem as it is a particularly difficult example of attempting to recover a signal from noise. To date most EIT scanners and algorithms have been designed for 2D applications. This simplifying assumption was originally used due to the prohibitive computational complexity of solving the larger 3D problem. Contemporary PC's can now calculate 3D solutions, however at the start of this thesis the prevailing algorithms in clinical use remain 2D models that rely on ad hoc tweaking to produce useful reconstructions. The aim of this thesis is to develop enhancements in EIT image reconstruction for 3D lung imaging; to remove some of the limitations that continue to impede its routine use in the clinic. The aim is attained through the systematic achievement of the following four main objectives: (1) Improve the method of hyperparameter selection in order to eliminate case by case tweaking of parameters, provide repeatability of experiments, and reduce the number of reconstructions needed to find the best reconstruction for a given data set. (2) Increase the resolution of 3D models by increasing the number of elements in the Finite Element Model (FEM). This requires the development of an algorithm to solve the large inversion using readily available computers. (3) Determine the best way to collect 3D data from the chest given some equipment limitations and a specific set constraints concerning electrode placement. (4) Determine the viability of non-blurring regularization for 3D lung imaging. The bulk of this thesis describes how the four objectives were successfully addressed with the result that some of the major limitations discouraging and preventing the routine use of 3D models for lung imaging have been eliminated. This thesis concludes with a recommendation for how to collect and reconstruct 3D EIT images of the lungs.

description: Nitrogen is an essential nutrient for all living beings. However, many compounds containing nitrogen are harmful for the environment. Plant species adapted to nutrient-poor conditions are displaced from forests and heathland. Emissions of nitrous oxide from over-fertilized fields exacerbate climate change. In many places, manure is responsible for nitrate concentrations in groundwater climbing above the limit values. Excessive levels of nitrogen dioxide in ambient air from transport sources present a risk to human health. This analysis shows that nitrogen pollution can be markedly reduced. Since agriculture accounts for around two-thirds of nitrogen emissions in Germany, efforts should focus on this sector.

Student perceptions of a self-regulatory approach to second language listening comprehension development
Creators: name: Mareschal, Catherine
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2007
Subjects: subject: Education, Bilingual and Multicultural.

description: This study investigated: (1) the effects of a process-based, self-regulatory approach to second language (L2) listening instruction on language learners' (a) metacognitive awareness, (b) self-regulatory abilities, (c) listening comprehension strategy use, and (d) overall success in listening comprehension, (2) the interrelationships between language learners' metacognitive awareness, self-regulatory abilities, listening comprehension strategy use, and their overall success in listening comprehension, and (3) language learners' perceptions and attitudes towards a self-regulatory approach to L2 listening comprehension development. The participants came from two small groups of native anglophone Canadian federal government employees enrolled in a mandatory French as a L2 learning program. One group, at the beginner-intermediate level, had been assessed by the learning institution as low-achievers; the other group, at the intermediate-advanced level, had been assessed as high-achievers. Six data collection instruments---questionnaires, stimulated recalls, think-alouds, interviews, listening note-books, and observation---were cyclically used to complement, explain, and verify the findings elicited by each instrument in the investigation of the research questions. In addition, at the end of the study, the students and their instructors completed individual summative reports of evaluation of the pedagogical method investigated in this research. All sources of data concur in indicating that low- and high-proficiency students responded positively to the pedagogical approach examined, and that this method exerted beneficial effects on low- and high-proficiency students' metacognitive awareness, strategy use, and on their confidence and interest in L2 listening. The beneficial effects of this approach are most evident in the case of the low-proficiency students, whose think-aloud protocols reveal a considerable improvement in listening comprehension success over the course of the nine week listening training. This study provides detailed insights into the components of metacognitive, self-regulatory, and strategic knowledge---as well as individual listener characteristics---which influence L2 listeners' comprehension, and into the intricate interrelationships among these factors. The study also provides detailed insights into the advantages and drawbacks of the various instruments which can be utilized in L2 listening research. These methodological findings underscore the necessity for rigorous data triangulation in the investigation of the covert processes underlying listening comprehension.

description: Applications of smart structures equipped with real time monitoring of structural integrity are expanding rapidly. In the present thesis, a non-destructive testing method was used to detect damage in a simple beam-like smart structure. In this study, two continuous beams perfectly connected, one of them equipped with a piezoceramic sensor and two piezoceramic actuators, were used to identify the changes in the boundary conditions. A non-destructive damage detection method for this simple smart structure was applied to two extreme cases. These cases were: two beams with a perfect connection and the original beams completely disconnected. Transient responses for the two cases were compared and the differences were analyzed for detecting the presence of damage. To illustrate the approach, the classic Euler-Bernoulli beam model for vibration analysis was used. Computer simulations based on the analytical modeling were performed. A quantitative measure of the safety of the beam and an index of safety were introduced. Experimental verification of the concept of the method was successfully carried out. The results confirm the feasibility of the proposed structural integrity monitoring method.

description: Metallothionein-II (MT-II) is an ubiquitously expressed small-molecular-weight protein and highly induced in various species and tissues upon stress, inflammation, and ischemia. MT-deficiency exacerbates ischemic injury in rodent stroke models in vitro and in vivo. However, there is conflicting data on the potential neuroprotective effect of exogenously applied metallothionein. Thus, we applied MT-II in an in vitro stroke model and intraperitoneally (i.p.) in two in vivo standard models of transient middle cerebral artery occlusion (MCAO) (a ‘stringent’ one [60min MCAO/48h reperfusion] and a ‘mild’ one [30min MCAO/72h reperfusion]), as well as i.v. together with recombinant tissue plasminogen activator (rtPA) to evaluate if exogenous MT-II-application protects against ischemic stroke. Whereas MT-II did not protect against 60min MCAO, there was a significant reduction of direct and indirect infarct volumes and neurological deficit in the MT-II (i.p.) treated animals in the ‘mild’ model at 3d after MCAO. Furthermore, MT- II also improved survival of the mice after MCAO, suppressed TNF-α mRNA induction in ischemic brain tissue, and protected primary neuronal cells against oxygen-glucose-deprivation in vitro. Thus, exogenous application of MT-II protects against ischemic injury in vitro and in vivo. However, long- term studies with different species and larger sampling sizes are required before a clinical use can be envisaged.

description: This dissertation investigates the placement of object pronouns in Middle French infinitival constructions. The working hypothesis of this thesis is that the evolution of the placement of object pronouns is due to changes in the lexical properties of AGR and INFL rather than to a new type of subcategorization of the main verb. The analysis of the placement of object pronouns is based on a study of two texts of the Middle French period, Les Cent Nouvelles Nouvelles de Vigneulles and Les Cent Nouvelles Nouvelles Anonymes.

description: Background: Pharmacotherapy is paramount to the management of systemic autoimmune rheumatic diseases (SARDs), yet there is sub-optimal adherence and limited adherence interventions. To understand how to better support patients’ medication use, our two-fold objectives were: 1) to conduct a systematic review of qualitative research studies of medication taking among SARD patients; and 2) to thematically synthesize qualitative research studies to obtain SARD patients’ perspectives and experiences with medication use. Methods: We conducted a search of MEDLINE, EMBASE, Cumulative Index to Nursing and Allied Health Literature, and Social Sciences Citation Index databases to identify qualitative research studies exploring views on medication use among patients with SARDs, their healthcare providers, or caregivers. We used thematic synthesis to combine data from selected studies, and identify analytical themes on SARD patients’ perspectives and experiences with medication use. Results: Our systematic review identified 18 studies. Thematic synthesis identified seven analytical themes: 1) effects of medications on emotional and social well-being, 2) impacts of healthcare provider relationships on treatment, 3) gaining control over treatment, 4) fear and concern with side effects of treatment, 5) understanding the importance of treatment, 6) practical barriers to taking medication, and 7) motivation towards adherence to treatment. Conclusion: This systematic review and thematic synthesis contributes to better understanding of SARDs patients’ perspectives on medication use. Given the paucity of existing adherence interventions targeting this patient population, our study has certain practical implications for care, namely the need to address emotional and social impacts of medication use and the necessity of establishing a meaningful and trusting professional relationship with patients.

description: Background: Clozapine is an effective treatment for a proportion of people with schizophrenia (SZ) who are resistant to the beneficial effects of other antipsychotic drugs. However, anything from 40–60 % of people on clozapine experience residual symptoms even on adequate doses of the medication, and thus could be considered 'clozapine resistant'. Agents that could work alongside clozapine to improve efficacy whilst not increasing the adverse effect burden are both desired and necessary to improve the lives of individuals with clozapine-resistant SZ. N-Acetylcysteine (NAC) is one such possible agent. Previous research from our research group provided promising pilot data suggesting the efficacy of NAC in this patient population. The aim of the study reported here is to expand this work by conducting a large scale clinical trial of NAC in the treatment of clozapine-resistant SZ. Methods: This study is an investigator initiated, multi-site, randomised, placebo-controlled trial. It aims to include 168 patients with clozapine-resistant SZ, divided into an intervention group (NAC) and a control group (placebo). Participants in the intervention group will receive 2 g daily of NAC. The primary outcome measures will be the negative symptom scores of the Positive and Negative Syndrome Scale (PANSS). Secondary outcome measures will include: changes in quality of life (QoL) as measured by the Lancashire Quality of Life Profile (LQoLP) and cognitive functioning as measured by the total score on the MATRICS. Additionally we will examine peripheral and cortical glutathione (GSH) concentrations as process outcomes. Discussion: This large scale clinical trial will investigate the efficacy of NAC as an adjunctive medication to clozapine. This trial, if successful, will establish a cheap, safe and easy-to-use agent (NAC) as a ‘go to’ adjunct in patients that are only partly responsive to clozapine.

description: As a promising field, Multi-Query Image Retrieval (MQIR) aims at searching for the semantically relevant image given multiple region-specific text queries. Existing works mainly focus on a single-level similarity between image regions and text queries, which neglects the hierarchical guidance of multi-level similarities and results in incomplete alignments. Besides, the high-level semantic correlations that intrinsically connect different region-query pairs are rarely considered. To address above limitations, we propose a novel Hierarchical Matching and Reasoning Network (HMRN) for MQIR. It disentangles MQIR into three hierarchical semantic representations, which is responsible to capture fine-grained local details, contextual global scopes, and high-level inherent correlations. HMRN comprises two modules: Scalar-based Matching (SM) module and Vector-based Reasoning (VR) module. Specifically, the SM module characterizes the multi-level alignment similarity, which consists of a fine-grained local-level similarity and a context-aware global-level similarity. Afterwards, the VR module is developed to excavate the potential semantic correlations among multiple region-query pairs, which further explores the high-level reasoning similarity. Finally, these three-level similarities are aggregated into a joint similarity space to form the ultimate similarity. Extensive experiments on the benchmark dataset demonstrate that our HMRN substantially surpasses the current state-of-the-art methods. For instance, compared with the existing best method Drill-down, the metric R@1 in the last round is improved by 23.4%. Our source codes will be released at https://github.com/LZH-053/HMRN.
La traduction de la Bible à l'époque de la Réforme.

Subjects: subject: Religion, Biblical Studies.

description: This thesis undertakes to examine the translation of the Bible during the Reformation, i.e. in the 15th and 16th Centuries. The sudden and dramatic increase in Biblical translation during that era was such that the influence of this activity on the development of translation theory cannot be ignored. Bible translation has been the subject of numerous studies throughout the ages. The Reformation, however, stands out in this regard because of the special political, religious and cultural context of that time. In Part I of this paper, we provide an historical overview of the Reformation era. Part II is devoted to the proliferation of versions of the Bible published between 1450 and 1599 throughout Europe. In the third and final part, we observe translators at work, starting with a study of the profile of Reformation-era translators; we then examine their working conditions and take a brief look at the European vernaculars that were in existence during the Reformation. This is followed by our analysis of the main elements of theology and dogma that were at the centre of the controversies between the Catholic clergy and Reformation translators. Finally, via three case studies, we will examine the various work methods and principles applied by translators of that period.
Perspectives on popular music analysis: Towards a standarized approach.
Creators: name: Chaly, Maya Ann.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1999
Subjects: subject: Music.

description: This thesis investigates the potential for a standardized methodology for the study of popular music. It examines recent applications of voice-leading analysis and harmonic analysis to pop/rock songs and highlights common ground among them---commonalities that could contribute to a standardized methodology. In particular, the thesis focuses on the analytical approaches of Allan Moore, Walter Everett, and Lori Burns---leading scholars in the field. The underlying principles of each approach are illuminated through case studies of pop/rock songs by 1990s North American female singer-songwriters. After examining how scholars analyse the musical structure of pop/rock songs, the thesis considers the analysis of musical structure in association with text and vocality.
The ‘digital dividend’ as a case study in spectrum re-farming
Creators: name: Tanner, Giles
Publisher: name: Swinburne
Year: 2024

description: The re-farming of spectrum (i.e. its reassignment to services with a higher value), triggered by free-to-air television digitisation and the switch-off of analogue TV, represents a significant microeconomic reform. Digitisation has already transformed the television industry, and analogue TV switch-off will yield a ‘digital dividend’ for wireless broadband as well as further benefits to television itself. With soaring growth projections for mobile data traffic creating pressure for further spectrum allocations for wireless broadband, lessons learned from the digital dividend process are liable to influence government approaches to spectrum re-farming in future. This article considers the development, over two decades, of an original policy ‘blueprint’ for TV digitisation in Australia as a case-study in spectrum re-farming. While it is too early to judge its full effects, some preliminary lessons are drawn from the various approaches that have been considered and adopted or discarded along the way.
An evaluation of minimal clinically important differences for the initiation of antihypertensive therapy from the perspective of Canadian patients and physicians.

description: Background. Traditional hypertension guidelines from different countries or organizations often specified different treatment thresholds. These discrepancies have enormous public health implication. As the choice of treatment threshold is a utility-sensitive decision, determination of the preferences of practicing physicians and hypertensive patients is important for future policy making. Methods. A survey to determine the minimal clinically important differences (MCIDs) of patients and physicians for the initiation of antihypertensive therapy in the primary prevention of cardiovascular disease. Physicians were randomly selected from the population of all family physicians in the Ottawa-Carleton region and hypertensive patients without symptomatic cardiovascular disease were recruited from a convenience sample of five family physicians and four general internists. Both groups were presented with six hypothetical scenarios which described the same blood pressure (150/95 mm Hg) but different baseline cardiovascular risks (2%, 5%, and 10% in five years, and 15%, 30%, and 50% in twenty years). For each scenario, subjects were asked whether they would prescribe/accept treatment and, if they would, a probability trade-off technique was used to determine their MCID for antihypertensive therapy.

description: Quantum metrology has emerged as a promising avenue for surpassing the limitations of classical mechanics in high-precision measurements. However, the practical implementation of quantum metrology is hindered by the challenges of manipulating exotic quantum states in large systems. Here, we propose and demonstrate a hardware-efficient approach to achieve Heisenberg-limited quantum metrology using large photon-number Fock states. We have developed a programmable photon number filter that efficiently generates Fock states with up to 100 photons in a high-quality superconducting microwave cavity. Using these highly nontrivial states in displacement and phase measurements, we demonstrate a precision scaling close to the Heisenberg limit and achieve a maximum metrological gain of up to 14.8 dB. Our hardware-efficient quantum metrology can be extended to mechanical and optical systems and provides a practical solution for high metrological gain in bosonic quantum systems, promising potential applications in radiometry and the search for new particles.

description: Depressive symptoms in midlife and older adulthood are common, persistent, and associated with cardiovascular diseases, cognitive impairment, and earlier mortality. Previous research has identified risk factors for depressive symptoms in middle and older adulthood, such as increasing age, female sex, race and ethnicity, major life stressors, lack of social connectedness, neuroticism, lower life satisfaction, physical inactivity, alcohol use, and polygenic risk scores, to name a few. However, these multi-factorial predictors have not been included in the same study to determine their relative contribution to depressive symptoms in middle and older adulthood. Furthermore, previous research has only assessed depressive symptoms and their predictors cross-sectionally or prospectively (i.e., 2 time points), which misconstrues the dynamic temporal nature of depressive symptoms. Therefore, using data from the Health and Retirement Study (N = 13,994), the aims of this study were threefold: 1) estimate trajectories of depressive symptoms in middle-aged and older adults using growth mixture modelling (GMM), 2) identify predictors of trajectory groups in order of importance using random forest (RF) analysis, and 3) compare how trajectory groups differ in relation to the most important predictors using multinomial logistic regression (MLR). GMM indicated that there were five latent classes following distinct trajectories of depressive symptoms over 10 years: “consistently low”, “increasing”, “consistently moderate”, “decreasing”, and “consistently high”. Out of a total of 72 predictors ranging from demographic to genetic factors, the top five predictors of depressive symptoms trajectories were trait anxiety, lower life satisfaction, neuroticism, perceived constraints, and hopelessness. MLR demonstrated that trajectory groups differed significantly in relation to psychological, health, and social factors, which highlights potential avenues for intervention.

description: Anthelmintic resistance is widespread in gastrointestinal nematode populations, such that there is a consistent need to search for new anthelmintics. However, the cost of screening for new compounds is high and has a very low success rate. Using the knowledge of traditional healers from Borneo Rainforests (Sarawak, Malaysia), we have previously shown that some traditional medicinal plants are a rich source of potential new anthelmintic drug candidates. In this study, Picria fel-terrae Lour. plant extract, which has previously shown promising anthelmintic activities, was fractionated via the use of a solid phase extraction cartridge and each isolated fraction was then tested on free-living nematode Caenorhabditis elegans and the parasitic nematode Haemonchus contortus. We found that a single fraction was enriched for nematocidal activity, killing ≥90% of C. elegans adults and inhibiting the motility of exsheathed L3 of H. contortus, while having minimal cytotoxic activity in mammalian cell culture. Metabolic profiling and chemometric analysis of the effective fraction indicated medium chained fatty acids and phenolic acids were highly represented.

description: Education as a journey of human becoming involves commitment to one’s ethical life project as well as learning to live well and actively participate with others in an ever-changing socio-cultural, political and material world. This paradoxical journey is at the heart of our philosophical criticism of contemporary policy impulses to formulate risk averse pedagogies which centre on a product model of outcomes. We draw from philosophical perspectives of liminality and the Productive Pedagogy study from Australia to inform our position by indicating how students make sense of pedagogical experiences in unique, deeply personal, corporeal and limitlessness ways. We use Aquatics Education as a useful symbolic representation for the immersive, embodied and relational practices involved in human becoming; practices that we aver need to be acknowledged, while never fully defined. These practices require teachers’ localised autonomous judgements in evaluating risk for dilemmas encountered. Holistic experiences, provided by games with gravity, are consistent with such ‘aesthetic experiences’ for primacy of the subject/subjective. Our affirmative critique reveals how immersive experiences occupy a defensible position for our concept of a Productive Pedagogy of Liminality, which aims to open affordances for each student’s ethical life project by heightening subjective awareness between body and spirit

Mechanisms affecting metal retention by surface-flow wetlands in cold temperate climates.
Creators: name: Goulet, Richard Roger.

description: The mechanisms affecting metal retention by surface-flow wetlands were investigated by relating variations in metal retention to variables such as hydraulic residence time, temperature (i.e. seasonal effects), phytoplankton biomass, photosynthesis and the presence of emergent vegetation. The importance of hydraulic residence time was investigated at the Monahan surface-flow wetland in Kanata, Ontario. This wetland retained metals best during summer and fall whereas during winter, the metal retention was significantly lower. The first-order removal model predicted Fe and Mn retention in the spring and Zn retention from spring to fall in both years of the study. Hydraulic residence times, greater than 7 days, provided the maximum retention of Fe, Mn, and Zn. However, first-order removal models failed to fit summer, fall and winter data for almost every metal under investigation (Fe, Mn, Cu, As) suggesting that hydraulic residence time (<1--25 days) do not regulate metal retention during these seasons. The Monahan wetland also affected the partitioning of metals between particulate and dissolved phases thus potentially affecting the bioavailability of metals to downstream systems. On a yearly basis, the wetland showed significant retention of the dissolved phase, but the retention of total Fe and Mn was poor. The wetland transformed dissolved into particulate metals from spring to fall whereas during the winter, dissolved metals were released. Changes in pH, alkalinity and temperature could explain 11% and 40% of the variation in the ratio of dissolved to total Fe and Mn respectively. Furthermore, from spring to late summer, planktonic algal biomass was negatively related to the ratio of dissolved to total Fe and Mn, which suggests the importance of phytoplankton in affecting the partitioning of metal in young plankton-dominated wetlands. In the Monahan wetland and in an acid mine drainage wetland (Falconbridge) near Sudbury, Ontario, diel changes in metal concentrations followed diel changes in pH and oxygen induced by photosynthesis. During the day, metal concentrations in the water column were low because high pH and oxygen favored the precipitation of Fe and Mn oxides at the sediment-water interface. At night, Fe and Mn oxides were reduced and released to the water column because intense biological respiration decreased oxygen and pH. Diel changes in metal concentrations have to be considered when evaluating the retention performance by surface-flow wetlands. Finally, the effect of emergent vegetation on the concentration and partitioning of metals in surface sediments of four wetlands was investigated. (Abstract shortened by UMI.)

description: Background and aims. In the past, wobble-boards have been used to help rehabilitate patients with ankle injuries. Balance-boards have also been used to improve strength and balance in athletes. For the elderly population, wobble-boards have been shown to improve measures related to ankle proprioception but have never been used specifically to improve balance with the goal of fall prevention. The objective of this study is to compare the effectiveness of two types of balance-boards (wobble-board and rocker-board) to improve balance in elderly. The focus of the study is to measure any changes to functional balance, attentional demand while performing two tasks (dual task), postural sway during quiet standing and ankle joint dorsiflexion discrimination. Twenty-eight healthy elderly, 12 in the wobble-board group (age = 72.9 +/- 4.62), 11 in the rocker-board group (age = 73.5 +/- 4.08) participated in an 8-week intervention consisting of three sessions per week, 20 minutes each session. There were 5 elderly in the control group (age = 76.2 +/- 5.49). Baseline, post-training and retention measures of functional balance (CB&M), attentional demand, static balance (sway) and dorsiflexion discrimination were collected. Following the intervention, experimental groups had significantly improved their dynamic functional balance scores (p < 0.001). Attentional demand and postural sway remained unchanged in all groups (p > 0.05). The wobble-board group significantly improved ankle dorsiflexion discrimination (p < 0.001); however, the control group also improved (p < 0.05). In conclusion, balance-boards were effective for improving functional balance needed for daily activities. Lastly, more investigation is needed to assess the effect of a balance-board intervention on static balance and ankle dorsiflexion discrimination.
Studies on the molecular and functional analysis of tail-anchored membrane associated protein (SLMAP) in Drosophila melanogaster

description: Previous work in our lab identified a novel gene encoding a unique family of tail-anchored alpha-helical coiled-coil proteins termed SLMAPs (sarcolemmal membrane associated proteins) that were highly conserved in rodents and humans. Alternative splicing yields three SLMAP isoforms: a ubiquitously expressed isoform (SLMAP3), and two tissue-specific variants (SLMAP1 and SLMAP2). The salient features of SLMAP are a hydrophobic C-terminal sequence, which targets membranes, a central coiled-coil structure and N-terminal fork head associated domain (FHA). A sequence in fruit flies (corresponding to CG17494 in flybase) was identified that shares 28.6% identity with the full-length mammalian SLMAP3 amino acid sequence. However, a 55.9% identity was identified at the fork head associated domain of Drosophila and SLMAP3 isoform, whereas a 25% identity was shared at the C-terminal transmembrane domain. The rest of the protein was predicted to form a coiled-coil structure. In view of these similarities with the mammalian SLMAP3 isoform, this Drosophila gene was designated Dslmap. In situ hybridization on whole mount embryos revealed a ubiquitous expression of Dslmap mRNA throughout various stages of embryonic development. To study the function of Dslmap during embryonic development, a GAL4-driven hairpin-induced RNA interference (RNAi), as well as overexpression experiments were performed. The Gal4/UAS binary system was used to allow hairpin RNA to conditionally silence Dslmap expression in Drosophila. A pan-neuronal driver (Elav-Gal4) that expresses GAL4 in every cell of the nervous system from embryogenesis onward was mated to transgenic flies carrying the activatable Dslmap RNAi vectors. The resulting phenotypes revealed dramatic defects in the development of axon scaffold in the fly central nervous system (CNS) with particular structural defects within the longitudinal connectives and commissures. An overexpression construct was also made using pUAST vector carrying the full length Dslmap cDNA in frame with a yeast upstream activator sequence (UAS) to generate transgenic lines. Overexpression in the transgenic lines was activated by mating with the CNS Gal4 lines, which resulted in phenotypes that revealed similar defects in the CNS to those observed in the RNAi lines. These data revealed that the Drosophila genome contains a SLMAP homologue, which is ubiquitously expressed and plays a critical role in developing neurons and glia.

description: This research applies quantitative approach to estimate the cost of protecting the domestic car maker in Malaysia. The approach taken involves investigating factors that influence the demand for domestic and foreign cars in Malaysian, and measuring car buyers' sensitiveness to price changes. Results of this research contribute to manufacturing sector in that product characteristics influence the demand for differentiated goods. Results also suggest that trade barriers may not be effective to reduce imports if foreign product characteristics are attractive and income level in the domestic economy is sufficiently high. The research concludes that trade barriers impose costs on society.

description: Williamson's theorem states that for any $2n \times 2n$ real positive definite matrix $A$, there exists a $2n \times 2n$ real symplectic matrix $S$ such that $S^TAS=D \oplus D$, where $D$ is an $n\times n$ diagonal matrix with positive diagonal entries which are known as the symplectic eigenvalues of $A$. Let $H$ be any $2n \times 2n$ real symmetric matrix such that the perturbed matrix $A+H$ is also positive definite. In this paper, we show that any symplectic matrix $\tilde{S}$ diagonalizing $A+H$ in Williamson's theorem is of the form $\tilde{S}=S Q+\mathcal{O}(\|H\|)$, where $Q$ is a $2n \times 2n$ real symplectic as well as orthogonal matrix. Moreover, $Q$ is in $\textit{symplectic block diagonal}$ form with the block sizes given by twice the multiplicities of the symplectic eigenvalues of $A$. Consequently, we show that $\tilde{S}$ and $S$ can be chosen so that $\|\tilde{S}-S\|=\mathcal{O}(\|H\|)$. Our results hold even if $A$ has repeated symplectic eigenvalues. This generalizes the stability result of symplectic matrices for non-repeated symplectic eigenvalues given by Idel, Gaona, and Wolf [$\textit{Linear Algebra Appl., 525:45-58, 2017}$].
