description: Fetal overgrowth is associated with adverse outcomes for offspring and with maternal obesity. Results from a systematic review and meta-analysis showed that maternal obesity is associated with fetal overgrowth, defined as birthweight ≥4000g (OR 2.17, 95% CI 1.92, 2.45), birthweight ≥4500g (OR 2.77, 95% CI 2.22, 3.45) and birthweight ≥90%ile for gestational age (OR 2.42, 95% CI 2.16, 2.72). A retrospective cohort study revealed that mothers whose infants are macrosomic are more likely to require induction of labour (OR 1.42, 95% CI 1.10-1.98) and delivery by Cesarean section (OR 1.45, 95% CI 1.04-2.01), particularly for maternal indications (OR 3.7, 95% CI 1.47-9.34), if they are obese. Infants from these pregnancies are significantly more likely to require neonatal resuscitation in the form of free flow oxygen (OR 1.57, 95% CI 1.03, 2.42) than macrosomic infants of non-obese mothers. Thus, co-existing maternal obesity and macrosomia increases the risk of adverse pregnancy outcomes.

description: In order to simulate realistic traffic scenarios, a radar target simulator must be able to generate multiple radar targets with different directions of arrival. The presented concept is able to generate an arbitrary amount of targets with individual directions of arrival for the radar under test. By measuring the radar channel, the novel approach enables target simulators to simulate arbitrary directions of arrival, while minimizing the required hardware. The optimum setup is derived for radars with a uniform linear receive antenna array. The compensation of placement errors for automotive chirp-sequence frequency modulated continuous wave radars is demonstrated. Finally, the calibration for the setup is provided, and the performance of the presented approach is validated.
The detection and fate of bromine atoms and beta-bromo radicals generated via the photochemical debromination of vicinal dibromides in acetonitrile.

description: The photolysis of vicinal dibromoalkanes in acetonitrile produces bromine atoms and $\beta$-bromoalkyl radicals. Bromine atoms react with halide ions to produce easily detectable and long-lived radical anions $\rm (BrX\sp{\sbsp{\!-}{\bullet}}).$ The reaction of photolytically produced bromine atoms with iodide, bromide, chloride, and fluoride occurs with rate constants of (1.4 $\pm$ 0.8) $\times$ 10$\sp $ M$\sp{-1}$ s$\sp{-1}$, (1.6 $\pm$ 0.3) $\times$ 10$\sp $ M$\sp{-1}$ s$\sp{-1}$, (1.4 $\pm$ 0.1) $\times$ 10$\sp $ M$\sp{-1}$ s$\sp{-1},$ and (1.0 $\pm$ 0.1) $\times$ 10$\sp $ M$\sp{-1}$ s$\sp{-1}$, respectively in acetonitrile. The formation of the Br$\sb2\sp{\sbsp{\!-}{\bullet}}$ radical anion was found to have an activation energy of $1.9\pm 0.4$ kcal/mol and a logA factor of $11.6\pm 0.3.$ These radical anions have extinction coefficients of $\rm (13\pm 1)\times 10\sp3\ M\sp{-1}\ cm\sp{-1}$ (BrI$\rm\sp{\sbsp{\!-}{\bullet}}),\ (9\ \pm\ 1)\ \times\ 10\sp3\ M\sp{-1}\ cm\sp{-1}\ (BrCl\sp{\sbsp{\!-}{\bullet}}),$ and $\rm (6.9\pm 0.7)\times 10\sp3\ M\sp{-1}\ cm\sp{-1}\ (BrF\sp{\sbsp{\!-}{\bullet}})$ at 360 nm in MeCN. The formation of the $\rm BrX\sp{\sbsp{\!-}{\bullet}}$ radical anions can be used to probe the dynamics of the decays of $\beta$-bromoalkyl radicals. For example, the lifetimes of the $\beta$-bromoethyl and $\beta$-bromocyclopentyl radicals were determined to be 145 ns and 100 ns, respectively. The halides were found to reduce the $\beta$-bromoalkyl radicals with rate constants in the $\rm 10\sp9\ M\sp{-1}\ s\sp{-1}$ regime. For example, the bromide, chloride, and fluoride reduction rate constants were determined for the reaction with the $\beta$-bromocyclopentyl radical to be $\rm (3.2\pm 0.3)\times 10\sp9\ M\sp{-1}\ s\sp{-1},\ (2.0\pm 0.2)\times 10\sp9\ M\sp{-1}\ s\sp{-1},$ and $\rm (1.3\pm 0.1)\times 10\sp9\ M\sp{-1}\ s\sp{-1},$ respectively. The activation energies and log(A) factors were determined for the temperature dependence of the bromide reduction of the $\beta$-bromocyclopentyl radical to be $3.3\pm 0.5$ kcal/mol and $11.8\pm 0.5$ and for the fluoride reduction of the $\beta$-bromoethyl radical to be $4.0\pm 0.5$ kcal/mol and $12.2\pm 0.5.$

Subjects: subject: Health Sciences, Nursing.

description: This descriptive correlational study explored the relationship between perceived social support and perceptions of illness for individuals living with New York Heart Association Class Two or Class Three congestive heart failure. A total of 34 participants were interviewed at the University of Ottawa Heart Institute, Ambulatory Heart Failure Clinic. Participants completed three questionnaires, which included a demographic questionnaire, a social support questionnaire (PRQ-85/Part Two), and the Meaning of Illness Questionnaire (MOIQ). Results indicated that subjects perceived their social support to be high. Perceived social support was seen to account for 24% of the variance in MOIQ Factor 3 (degree of stress, change in commitments, and secondary coping resources to deal with it), and 11% of the variance in MOIQ Factor 2 (type of stress, negative attitude of harm, loss or threat, and viewing the illness as disabling, disfiguring and deteriorating). Content analysis revealed six major themes which described the subjects' feelings about how heart failure had affected their lives. The themes that were elicited were: physical limitations, surprise and disbelief, a need for knowledge, adjustment, support from significant others, and getting in touch with one's spirituality.

Strategic issues for facility provision: a re-examination of the NIMBY phenomenon

Publisher: name: Swinburne

description: The conflict between the provision of facilities that provide public service and the community responses to those facilities is of crucial concern to those planning and managing such facilities. The NIMBY (Not In My Back Yard) phenomenon exemplifies a community response to the provision of facilities intended to provide public service. The facilities may be provided either by government or the private sector. This paper uses content analysis to examine the language used in the public domain from a recent NIMBY case in Melbourne, Victoria and the NIMBY literature. The NIMBY literature contains approaches that treat the responses to facilities as reasoned and rational, the result of ignorance, or are irrational and selfish. A re-examination of the language used shows that this is a limited interpretation of the responses. The public domain language from the local newspaper provides a case study of the, particularly, community responses to the issue of facility provision. A number of response modes are possible, however, the language used in both instances suggests that affective responses are a dominant response mode. An understanding of affective responses to facility provision is important to providers of such facilities and the strategic management of their processes in planning for and providing service facilities.

L'essai proposé ici--car il s'agit bien d'un essai--se voudra donc un examen de quelques-unes de leurs vues et visions, et partira à la recherche d'une cohérence possible dans les manières dont le Vieux continent a pris conscience, par la voix des intellectuels, de ce qu'on nomme ordinairement les Temps modernes .

A new search technique for mining relationship rules.
Creators: name: Elazmeh, William Wasim.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2001
Subjects: subject: Information Science.

description: Data Mining is extracting knowledge from data. Knowledge may be presented using rules which express relationships between sets of items involved in the rule. The nature and strength of the relationship is determined by an evaluation measure used to evaluate the rules. A relationship may correspond to an association, an implication, a correlation, a causality, a dependency, etc. This thesis considers the problem of finding the strongest N rules from transaction data. Existing algorithms (e.g. Apriori) employ search techniques based on Best-First Search methods which impose high demands on memory. Searching Depth-First solves this memory problem but can demand long execution time. This drawback can be avoided by using iterative deepening search where the Depth-First Search is run with a progressively relaxed search bound on each successive iteration. Relaxing the search bound can be based on various characteristics of the search space, such as a change in the tree depth (MSDD algorithm), or a change in the quality of states being explored. The key issue is the strategy by which the search bound is relaxed for subsequent iterations. We propose an iterative deepening search algorithm IDGmax using a search bound strategy based on the quality of states explored. We explore different methods for relaxing the search bound to improve the performance. We present experimental results to evaluate the performance of these search bound relaxation strategies and compare them to the MSDD algorithm. We also show that the choice of the search bound relaxation method can significantly influence the performance of the rule mining algorithm in both memory and time.

description: À l'heure de l'hyperconsommation, de l'hypersexualité et de l'individualisme ou les grandes vérités s'effondrent, le couple, en tant que modèle unissant deux personnes dans l'exclusivité amoureuse et sexuelle, éclate. Adoptant la forme d'un roman épistolaire, la première partie de la thèse en création littéraire, Sarcophages mon amour, nous aurons vécu nous non plus, témoigne du vide suscité par une certaine désubstantialisation du couple et de l'apparition d'une nouvelle réalite amoureuse. La deuxième partie, L'analyse du vide postmoderne, approfondit la définition de ce mal-être contemporain lié à la perte de sens des modèles amoureux. Dans un premier temps, certaines notions théoriques ont permis de mieux saisir les enjeux philosophiques, sociologiques et littéraires du vide postmoderne. Dans un deuxième temps, j'ai mis l'accent sur trois romans québécois qui ont fait du vide postmoderne leur trame de fond: Le principe du geyser de Stéphane Bourgignon, Marie-Hélène au mois de mars de Maxime-Olivier Moutier et Unless d'Hélène Monette. J'ai effectué enfin un retour sur Sarcophages mon amour, nous aurons vécu nous non plus, tout en explicitant le lien qui unit le vide au genre épistolaire. En somme, ma thèse offre une perspective à la fois créatrice et critique du vide postmoderne.

description: The objective of this study is to estimate the real time travel times on urban networks that are partially covered by moving sensors. The study proposes two machine learning approaches; the random forest (RF) model and the multi-layer feed forward neural network (MFFN) to estimate travel times on urban networks which are partially covered by moving sensors. A MFFN network with three hidden layers was developed and trained using the back-propagation learning algorithm, and the neural weights were optimized using the Levenberg–Marquardt optimization technique. A case study of an urban network with 100 links is considered in this study. The performance of the proposed models was compared to a statistical model, which uses the empirical Bayes (EB) method and the spatial correlation between travel times. The models’ performances were evaluated using data generated from VISSIM microsimulation model. Results show that the machine learning algorithms, e.g., RF and ANN, achieve average improvements of about 4.1% and 2.9% compared with the statistical approach. The RF, MFFN, and the statistical approach models correctly predict real time travel times with estimation accuracies reaching 90.7%, 89.5%, and 86.6% respectively. Moreover, results show that at low moving sensor penetration rate, the RF and MFFN achieve higher estimation accuracy compared with the statistical approach. At probe penetration rate of 1%, the RF, MFFN, and the statistical approach models correctly predict real time travel times with estimation accuracy of 85.6%, 84.4%, and 80.9% respectively. Furthermore, the study investigated the impact of the probe penetration rate on real time neighbor links coverage. Results show that at probe penetration rates of 1%, 3%, and 5%, the models cover the estimation of real time travel times on 73.8%, 94.8%, and 97.2% of the estimation intervals.

The In-tel QX3 Computer Microscope contains no eyepieces, and images must be viewed through the accompanying software on the host computer that controls the mi-croscope. Construction materials used in the assembly of the microscope are typi-cal of those found in many modern toys. The ease of use in lighting and recording images is its main strengths and the time lapse photography is an especially desir-able feature. The microscope has excellent potential as an educational toy.

description: Toxoplasma gondii (T. gondii) is a parasite infecting animals and humans. In intermediate hosts, such as humans or rodents, rapidly replicating tachyzoites drive vigorous innate and adaptive immune responses resulting in bradyzoites that survive within tissue cysts. Activation of the innate immune system is critical during the early phase of infection to limit pathogen growth and to instruct parasite-specific adaptive immunity. In rodents, dendritic cells (DCs) sense T. gondii through TLR11/12, leading to IL-12 production, which activates NK cells to produce IFN-γ as an essential mechanism for early parasite control. Further, C3 can bind to T. gondii resulting in limited complement activation. Here, we determined the role of C5a/C5aR1 axis activation for the early innate immune response in a mouse model of peritoneal T. gondii infection. We found that C5ar1−/− animals suffered from significantly higher weight loss, disease severity, mortality, and parasite burden in the brain than wild type control animals. Severe infection in C5ar1−/− mice was associated with diminished serum concentrations of IL-12, IL-27, and IFN-γ. Importantly, the serum levels of pro-inflammatory cytokines, including IL-1α, IL-6, and TNF-α, as well as several CXC and CC chemokines, were decreased in comparison to wt animals, whereas anti-inflammatory IL-10 was elevated. The defect in IFN-γ production was associated with diminished Ifng mRNA expression in the spleen and the brain, reduced frequency of IFN-γ+ NK cells in the spleen, and decreased Nos2 expression in the brain of C5ar1−/− mice. Mechanistically, DCs from the spleen of C5ar1−/− mice produced significantly less IL-12 in response to soluble tachyzoite antigen (STAg) stimulation in vivo and in vitro. Our findings suggest a model in which the C5a/C5aR1 axis promotes IL-12 induction in splenic DCs that is critical for IFN-γ production from NK cells and subsequent iNOS expression in the brain as a critical mechanism to control acute T. gondii infection.

description: The goal of the Gemini Deep Deep Survey (GDDS) is to study an unbiased sample of K < 20.6 galaxies in the redshift range 0.8 < z < 2.0. Here we determine the statistical properties of the heavy-element enrichment in the interstellar medium (ISM) of a subsample of 13 galaxies with 1.34 < z < 1.97 and UV absolute magnitude M2000 < -19.65. The sample contains 38% of the total number of identified galaxies in the first two fields of the survey with z > 1.3. The selected objects have colors typical of irregular and Sbc galaxies. Strong [O II] emission indicates high star formation activity in the H II regions (star formation rate ∼13-106 M⊙ yr -1). The high signal-to-noise ratio composite spectrum shows strong ISM Mg II and Fe II absorption, together with weak Mn II and Mg I lines. The Fe II column density, derived using the curve of growth analysis, is log N Fe II = 15.540.13+0.23. This is considerably larger than typical values found in damped Lyα systems (DLAs) along QSO sight lines, where only 10 of 87 (∼11%) have log NFe II ≥ 15.2. High Fe II column densities are observed in the z = 2.72 Lyman break galaxy cB58 (log NFe II ≃ 15.25) and in gamma-ray burst host galaxies (log NFe II ∼ 14.8 - 15.9). Given our measured Fe II column density and assuming a moderate iron dust depletion (δFe ∼ 1 dex), we derive an optical dust extinction of AV ∼ 0.6. If the H I column density is log NHI < 21.7 (as in 98% of DLAs), then the mean metallicity is Z/Z⊙ > 0.2. The high completeness of the GDDS sample implies that these results are typical of star-forming galaxies in the 1 < z < 2 redshift range, an epoch that has heretofore been particularly challenging for observational programs.
Engaging the dragon: the need for cultural intelligence
Creators: name: Lye, William
Publisher: name: Swinburne
Year: 2024

description: Australia's proximate geographical location to South East Asia gives it a unique advantage over other Western countries. For example, China was Australia's largest two-way trading partner in 2007 for imports and exports of both goods and services. More recently, the Australia-New Zealand free trade agreement was signed with ASEAN. While China has dominated the media and India is a close second, it is now considered that ASEAN is Australia's largest trading partner. Without a doubt, the rise of the South East Asian and Chinese economies is transforming the way in which the West and East engage in trade and commerce. Yet, there are remarkable differences in attitudes, behaviours, gestures, and philosophy which are often misunderstood. There is also much trepidation in doing business in certain Asian economies including a lack of confidence in the legal system to resolve disputes. Rightly or wrongly, such perceptions do not help if Australia is to take the relationship with our Asian neighbours to another level. In order to develop and maintain effective ties in South East Asia, having 'cultural intelligence' is essential in sustaining a longer term relationship with the 'Asian dragon'. The challenge, however, of mutual understanding is vast but unless it is embraced, we will lose ground.

description: Background. Recurrent glomerulonephritis is third most common cause of kidney transplant failure. Methods. We used the United States Renal Data System to determine the association of routine post-transplantation immunosuppressant use with time to renal allograft failure due to recurrent glomerulonephritis. Immunosuppressants were treated as time-varying covariates. The study-cohort included patients with kidney failure due to glomerulonephritis who received first kidney transplant between 1990 and 2003. Important confounders were identified through a systematic review of literature and missing values in the dataset were handled by multiple imputation. Results. The study cohort included 41,272 patients with a median follow-up of 51 (22--90) months. Ten-year overall graft survival (including death as graft loss) and death-censored graft survival was 56.2% (55.5%--56.9%) and 70.5% (69.8%--71.1%) respectively. Ten-year incidence of graft loss due to recurrent glomerulonephritis was 2.6% (2.3--2.8%). Use of cyclosporine, tacrolimus, azathioprine or mycophenolate mofetil was not associated with risk of graft failure due to recurrent glomerulonephritis alter adjusting for important covariates. There was no difference of recurrent glomerulonephritis causing graft failure between cyclosporine and tacrolimus or between azathioprine and mycophenolate mofetil. Change in any immunosuppressant during follow-up was independently associated with graft loss due to recurrence (HR 1.31, 95%CI 1.07--1.60, p=0.01). Conclusion. Routinely used post-transplantation immunosuppressants have no impact on the risk of graft loss due to recurrent glomerulonephritis.

description: This thesis analyses the effect of encrypting data on the bit error rate at the receiver. Block and stream cipher modes based on the Data Encryption Standard (DES) are examined. More specifically, Electronic Code Book (ECB), Cipher Block Chaining (CBC), Output FeedBack (OFB) and Cipher FeedBack (CFB) modes are considered. The ability of binary BCH codes and of bit interleaving to reduce the error rate over fading channels is examined in detail. Experimental results are derived from computer simulations where the digital mobile communication channel is represented by the Gilbert and Fritchman models. Simulations are also carried out over memoryless binary symmetric channels (BSC) to illustrate the difference on the error rate at the receiver (after decryption) as a result of the presence or absence of channel memory.

description: A bright future? Ammonia is of utmost importance for fertilizer production and recently gained interest as a future hydrogen storage material. However, photocatalytic production of ammonia suffers from stagnating materials development and unstandardized reaction conditions. This Review reports on recent materials and reaction engineering results, emphasizing the need to connect the activity of reported materials together with detailed reaction conditions and efficiencies. Research will strongly benefit from joint efforts between chemists, physicists and chemical engineers already at a fundamental level. Ammonia is not only the most important chemical for fertilizer production, it has also gained much interest as a future hydrogen storage material. Besides the well‐known Haber–Bosch process to generate ammonia from elemental sources, new ways to convert nitrogen into ammonia have been investigated in the last decade for a decentralized production, including electrocatalytic and photocatalytic approaches. However, photocatalysis in particular suffers from stagnating materials development and unstandardized reaction conditions. In this Review, we shine light on recent materials and reaction engineering results for photocatalytic nitrogen reduction, putting an emphasis on the need to connect the activity of reported materials together with detailed reaction conditions and efficiencies. Photocatalytic nitrogen reduction is an emerging field that will certainly gain significant interest in the future as a sustainable pathway to generate green hydrogen and ammonia. The field will certainly strongly benefit from joint efforts with strong interactions between chemists, physicists and chemical engineers at a fundamental level.

description: Die Bedeutung der Technologievorausschau hat in den vergangenen Jahren bei allen Unternehmen zugenommen, die dem schnelldrehenden technologischen Wandel, schrumpfenden Entwicklungs­zyklen und insgesamt steigenden Wettbewerbsdruck stark oder weniger stark ausgeliefert sind. Der Blick in die Zukunft ist für eine erfolgreiche Gestaltung der technologischen Diversifikation unabding­bar. Wenn in der strategischen Planung das zukünftig notwendige Technologie-Portfolio abgeleitet werden soll, wünschen sich Entscheidungsträger eine solide Entscheidungsgrundlage und die „richti­gen“ Prognosen. Die Organisation dieser Prognosen bzw. der Blick in die Zukunft soll dabei möglichst zielgerichtet und systematisch durchgeführt werden. Das ITOP berücksichtigt in seiner Studie die Unterschiedlichkeit der Unternehmen und hat einen Ansatz entwickelt, der es ermöglicht, die Umsetzung der Technologievorausschau situativ in der Aufbau- und Ablauf-organisation des Unternehmens an dessen Charakteristika und die seines spezifischen Umfelds anzupassen.

description: Background: Adenoid cystic carcinoma (ACC) is a slow growing salivary gland malignancy that is molecularly characterized by t(6:9)(q22–23;p23–24) translocations which predominantly result in MYB-NFIB gene fusions in nearly half of tumours. Detection of MYB-NFIB transcripts is typically performed with fresh ACC tissue using conventional RT-PCR fragment analysis or FISH techniques, which are prone to failure when only archival formalin fixed paraffin embedded (FFPE) tissue is available. The purpose of this pilot study was to evaluate the utility of NanoString probe technology for the detection of MYB-NFIB transcripts in archival ACC tissue. Methods: A NanoString probeset panel was designed targeting the junctions of three currently annotated MYB-NFIB fusion genes as well as 5′/3′ MYB probesets designed to detect MYB gene expression imbalance. RNA isolated from twenty-five archival ACC specimens was profiled and analyzed. RT-qPCR and sequencing were performed to confirm NanoString results. MYB protein expression was analyzed by immunohistochemistry. Results: Of the 25 samples analyzed, 11/25 (44%) expressed a high degree of MYB 5′/3′ imbalance and five of these samples were positive for at least one specific MYB-NFIB variant in our panel. MYB-NFIB variant detection on NanoString analysis was confirmed by direct cDNA sequencing. No clinical correlations were found to be associated with MYB fusion status. Conclusion: We conclude that the application of NanoString digital probe counting technology is well suited for the detection and quantification of MYB-NFIB fusion transcripts in archival ACC specimens.

description: La nostra Costituzione, nell’ambito e nel rispetto dell’ordinamento giuridico, ha sancito l’Autonomia Universitaria, intesa come libertà delle istituzioni culturali di darsi propri ordinamenti, pur nei limiti della Legge dello Stato. La Carta Costituzionale si è preoccupata quindi di stabilire che ogni istanza innovativa passasse attraverso la libertà di pensiero, non solo degli insegnanti e dei loro interlocutori, ma anche degli stessi apparati istituzionali e del sistema delle fonti che ne governa il funzionamento. Nel contesto della formazione innovata, Scuole e Università sono andate così assumendo un ruolo sempre più attivo nella capacità di progettare, di prendere decisioni, di realizzare e gestire il sistema formativo e di cooperare costruttivamente al processo di rinnovamento del Paese. Tuttavia le Università italiane di oggi necessitano, pur nel contesto di una valida Legge ordinaria di riferimento (la legge 168/1989), che il concetto di Autonomia assuma significati più chiari e che, al tempo stesso, ogni processo riformatore sia accompagnato da risorse economiche precise che sappiano incentivare un sistema fortemente statale e pubblico con controlli che rendano conto dei rapporti tra costi e benefici.
