description: Time-resolved measurements of quantum dynamics are based on the availability of controlled events (e.g. pump and probe pulses) that are shorter in duration than the typical evolution time scale of the dynamical processes to be observed. Here we introduce the concept of noise-enhanced pump-probe spectroscopy, allowing the measurement of dynamics significantly shorter than the average pulse duration by exploiting randomly varying, partially coherent light fields consisting of bunched colored noise. It is shown that statistically fluctuating fields can be superior by more than a factor of 10 to frequency-stabilized fields, with important implications for time-resolved pump-probe experiments at x-ray free-electron lasers (FELs) and, in general, for measurements at the frontiers of temporal resolution (e.g. attosecond spectroscopy). As an example application, the concept is used to explain the recent experimental observation of vibrational wave packet motion in a deuterium molecular ion on time scales shorter than the average pulse duration.

description: In this paper we present a novel strategy to discover the community structure of (possibly, large) networks. This approach is based on the well-know concept of network modularity optimization. To do so, our algorithm exploits a novel measure of edge centrality, based on the k-paths. This technique allows to efficiently compute a edge ranking in large networks in near linear time. Once the centrality ranking is calculated, the algorithm computes the pairwise proximity between nodes of the network. Finally, it discovers the community structure adopting a strategy inspired by the well-known state-of-the-art Louvain method (henceforth, LM), efficiently maximizing the network modularity. The experiments we carried out show that our algorithm outperforms other techniques and slightly improves results of the original LM, providing reliable results. Another advantage is that its adoption is naturally extended even to unweighted networks, differently with respect to the LM.

description: We study two superluminal neutrino scenarios where δv\equiv (v-c)/c is a constant. To be consistent with the OPERA, Borexino, and ICARUS experiments and with the SN1987a observations, we assume that δv_ν on the Earth is about three order larger than that on the interstellar scale. To explain the theoretical challenges from the Bremsstrahlung effects and pion decays, we consider the deformed Lorentz invariance, and show that the superluminal neutrino dispersion relations can be realized properly while the modifications to the dispersion relations of the other Standard Model particles can be negligible. In addition, we propose the deformed energy and momentum conservation laws for a generic physical process. In Scenario I the momentum conservation law is preserved while the energy conservation law is deformed. In Scenario II the energy conservation law is preserved while the momentum conservation law is deformed. We present the energy and momentum conservation laws in terms of neutrino momentum in Scenario I and in terms of neutrino energy in Scenario II. In such formats, the energy and momentum conservation laws are exactly the same as those in the traditional quantum field theory with Lorentz symmetry. Thus, all the above theoretical challenges can be automatically solved. We show explicitly that the Bremsstrahlung processes are forbidden and there is no problem for pion decays.

description: Background: Prenatal anxiety is a common maternal mental health condition that affects both maternal and infant health. There are established associations between depression and reduced breastfeeding duration; however, little is known about the relationship between prenatal anxiety and breastfeeding outcomes. The objective of this study was to examine the association between prenatal anxiety and breastfeeding outcomes in a large longitudinal pregnancy cohort.Methods: Data were obtained from the All Our Families prospective community cohort of mother-infant pairs recruited in early pregnancy from Calgary, Alberta (n = 1473). Anxiety was measured with the State-Trait Anxiety Inventory (STAI) during early and late pregnancy. The primary outcome of breastfeeding duration and secondary outcomes (breastfeeding initiation, exclusivity, difficulties, and cessation) were self-reported at 4 and 12 months postpartum. Multivariable regression analyses were conducted to examine the associations between prenatal anxiety and each breastfeeding outcome while controlling for potential confounding variables as appropriate. Results: Overall, 18% of mothers reported clinically significant anxiety during pregnancy. Mothers with high prenatal anxiety reported shorter duration for any breastfeeding compared to those without (? = -4.43 weeks, [95% CI: -6.51, -7.94, -0.93)] after controlling for confounders. Having high prenatal anxiety was associated with lower odds of any breastfeeding at 4 months (OR = 0.68, [95% CI: 0.48, 0.95]) and 6 months (OR = 0.65, [95% CI: 0.54, 0.88]). No significant associations were observed between prenatal anxiety and breastfeeding initiation (AOR = 0.93, [95% CI: 0.42, 2.08]), exclusive breastfeeding for at least 4 months (AOR = 0.92, [95% CI: 0.66, 1.28]) and 6 months (AOR = 0.74, [95% CI: 0.45, 1.21]), or breastfeeding difficulties (AOR = 0.86, [95% CI: 0.48, 1.56]), respectively.Conclusion: Prenatal anxiety was associated with shorter breastfeeding duration and may be a risk factor for premature breastfeeding cessation. Targeted interventions specific to needs of mothers with prenatal anxiety may be beneficial in supporting optimal breastfeeding goals.

description: Several recent works have proposed that electron-electron interactions in bilayer graphene can be tuned with the help of external parameters, making it possible to stabilize different fractional quantum Hall states. In these prior works, phase diagrams were calculated based on a single Landau level approximation. We go beyond this approximation and investigate the influence of polarization effects and virtual interband transitions on the stability of fractional quantum Hall states in bilayer graphene. We find that for realistic values of the dielectric constant, the phase diagram is strongly modified by these effects. We illustrate this by evaluating the region of stability of the Pfaffian state.

The Trojan Horse Neutrophil: Mechanisms of Leishmania-Induced Neutrophil Cell Death

description: Recruited neutrophils are typically the first phagocytic cell to interact with the intraphagosomal pathogen Leishmania following vector-mediated inoculation into the mammalian dermis. Comparison of infected and uninfected neutrophils from the same site of infection has revealed that Leishmania modulates neutrophil cell death. However, the mechanism(s) by which Leishmania are internalized by neutrophils and how this modulates subsequent cell-viability have not been well characterized. In this study, we demonstrate that entry of Leishmania major (L. major) into neutrophils is dependent upon engagement of the neutrophil surface receptor, CD11b (CR3/Mac-1), and is enhanced by parasite opsonization with the third component of complement (C3), though extended periods of co-culture reveled that time-dependent, C3-independent, L. major uptake can occur. In each case, parasite internalization was not ‘silent’, as infected neutrophils accumulated intracellular reactive oxygen species (ROS) and maintained elevated expression of CD11b, though these neutrophils largely failed to eliminate internalized parasites. Infected neutrophils initiated an apoptotic phenotype as defined by increased phosphatidylserine externalization and NADPH phagocyte oxidase isoform 2 (NOX2)-influenced increase in transcription of Caspase 8 mRNA. However, neutrophils co-cultured with L. major also displayed an extended lifespan, Leishmania-surface-lipophosphoglycan (LPG)-mediated reduction in the levels of pro-caspase 3, reduced cleavage of executioner caspase 3 from pro-caspase 3, and upregulation of the anti-apoptosis genes Bcl-2 and Mcl-1. Together, our data suggest that Leishmania initiates a phagocytosis-induced cell death (PICD)-like program which is then arrested by parasite-dependant reduction in the cleavage of executioner caspase 3 from pro-caspase 3 – resulting in “stalled apoptosis” that may facilitate subsequent transition of the parasite from the neutrophil to a long term host cell via efferocytosis.

Dynamical behaviour of an aqueous foam in a liquid-filled Hele-Shaw cell

description: Foam, that is, a dispersion of gas bubbles in a liquid, is found in many of our products and processes, e.g., medical applications to cleaning agents to enhanced oil production. In contrast to a single-phase gas, foam exhibits a viscosity higher than the gas phase viscosity. In the research documented here, the miscible displacement of an aqueous foam with a dispersity of 30% and an average bubble radius of 68±2 ?m in a liquid-saturated Hele-Shaw cell is examined. The main goal of this experimental study is to investigate the influence of the dynamical surfactant dilution of foam on the interfacial flows in which the viscous force is favourable. Foam bubbles are categorized based on the gap thickness of the Hele-Shaw cell (b) into two groups: (i) small bubbles with a dimensionless average radius of 0.45?R ?/b?0.54, (ii) and large bubbles with 0.81?R ?/b?7.72. Movement of foam with various qualities (gas fractions) is monitored when the Hele-Shaw cell is initially filled with (i) DI-water and (ii) SOS at 17 times critical micelle concentration (CMC) that has the same surfactant concentration as the injected foam. Outcomes show that the displacement process remains stable in the surfactant-saturated Hele-Shaw cell whereas fingers of foam evolve in the water case. The growth of the ramifications, however, is retarded when the foam quality reduces. Since the total flow rate of the injected foam changes with the foam quality, another experiment is performed to decouple the impact of the flow rate from the surfactant dilution on the pattern formation. The injection of foam with a constant quality of 80% into (i) DI-water, (ii) 0.5CMC, and (iii) 17CMC elucidates that the uniform distribution of foam into 17CMC replaces with small interfacial perturbations when the Hele-Shaw cell is filled with 0.5CMC. The phase diagram of the pattern formation illustrating the effect of foam quality and surfactant concentration of defending fluid confirms that the highest interfacial deviation occurs when the foam with high quality is injected into a DI water-filled Hele-Shaw cell. The results suggest that water diffusion into the foam enhances the capillary force, which in turn promotes the ‘pinning’ of large foam bubbles separated from the solid surface by fragile thin films. The break-up of the lubricated thin films leads to a failure in the continuous movement of the large bubbles, thereby leading to a disturbance of the spatial distribution of foam flow and side branching patterns. This interfacial deformation can be aggravated through a local jamming structure when the number of small bubbles in a unit volume at the interface is higher than 50%.

description: We consider quantum dynamical systems specified by a unitary operator U and an initial state vector ϕ. In each step the unitary is followed by a projective measurement checking whether the system has returned to the initial state. We call the system recurrent if this eventually happens with probability one. We show that recurrence is equivalent to the absence of an absolutely continuous part from the spectral measure of U with respect to ϕ. We also show that in the recurrent case the expected first return time is an integer or infinite, for which we give a topological interpretation. A key role in our theory is played by the first arrival amplitudes, which turn out to be the (complex conjugated) Taylor coefficients of the Schur function of the spectral measure. On the one hand, this provides a direct dynamical interpretation of these coefficients; on the other hand it links our definition of first return times to a large body of mathematical literature.

description: This dissertation explores how changes in the microstructure of colloidal systems affect their microscopic behavior. Colloidal gels are well understood when they contain single type of particles, having either attractive or repulsive interactions, but this picture is significantly different when multi-component systems contain particles with heterogeneous surface charge in which repulsive and attractive interactions compete, at different length and time scales. I studied two different colloidal systems, namely mature fine oil sands tailings and binary cellulose-graphene oxide gel, the later serving as precursors for unidirectionally freeze-dried cryogels. My research quantitatively investigates these systems by linking their microstructure to their bulk rheological properties. By utilizing laser scanning confocal microscopy, flocculation process of mature fine tailings was, for the first time, monitored in real-time and demonstrated the evolution of floc structure. By 3D analysis of the flocculated sludge with polymers that differ in structure, charge and hydrophobicity, I demonstrated the effect of polymer structure on the flocculation efficiency and the subsequent dewatering. The flocculated sludge structure is characterized by the fractal dimension, characteristic length and volume occupied by the flocs. The approach has become a platform for understanding flocculation mechanism and subsequent screening of flocculants for treatment of MFT, but can be extended to other mineral slurries. In the case of binary cellulose nanofiber-graphene oxyde colloidal gels, the proposed approach allowed me to gain mechanistic understanding of the governing interactions that dictate the binary gel's and subsequent cryogel's properties and, as a result, achieve a precise control of the cryogel's morphology by pH sweep at the unprecedented loading of graphene oxide. The results show a very narrow region where the desirable honeycomb structure is attainable, directly related to the optimal balance between hydrogen bonding and electrostatic repulsion, evident through microstructure and rheological signature.

description: This thesis presents an experimental study of the phase equilibria of hexane/water and hexane/water/bitumen mixtures applicable to solvent-assisted thermal recovery processes. The solvent selection for solvent-aided thermal recovery processes is often chosen based on the proximity of solvent saturation properties to steam. In this thesis, such a premise is examined by evaluating the phase equilibria of hexane/water and hexane/water/bitumen mixtures to fill the existing knowledge gap and draw a conclusion on the validity of such a hypothesis.First, a PVT setup was used to measure the vapor-liquid equilibria (VLE) of hexane/water binary mixtures at temperatures ranging from 183-215 °C and a constant pressure of 2.5 MPa. The results indicate an azeotropic behavior with a co-condensation temperature of 183.7 °C at a hexane mole-fraction of 0.6029. The Cubic Plus Association Equation of State (CPA-EoS) and activity coefficient-based Non-Random Two Liquid (NRTL) models were used to model the measured experimental data, and the predicted results are in good agreement with the measured data. Next, the condensation properties of a solvent/water mixture in the presence of Mackay River Bitumen (ternary system) were performed. The phase behavior, viscosity, and density measurements were taken at two typical mole fractions of solvent (1 and 5%) in the steam/solvent mixture while keeping the hexane/bitumen ratio constant at temperatures ranging from 183-215 °C and a constant pressure of 2.5 MPa. The results revealed a vapor-liquid-liquid equilibrium (VLLE). The phases in equilibrium include a vapor phase consisting of hexane and water, a liquid phase comprising hexane/water bitumen, and a second liquid phase containing hexane/water. The condensation trends of the binary hexane/water and ternary hexane/water/bitumen systems were compared. The results revealed that the hexane concentration in the ternary systems is close to those of the binary mixture at any given temperature, suggesting that the binary system of solvent/water may be used for condensation studies. In addition, the results revealed that the solubility of hexane in bitumen dominates viscosity reduction at the temperature range of interest. The cubic-plus-association equation of state (CPA EoS) was used to model the phase equilibria of hexane/water and hexane/water/bitumen mixtures. The findings provide insight into steam/solvent condensation behavior with applications to the solvent-aided thermal recovery of bitumen from oil sands.

description: The field-angular dependence and anisotropy of the critical current density in iron-based superconductors is evaluated using a phenomenological approach featuring distinct anisotropy factors for the penetration depth and the coherence length. Both the weak collective pinning limit, and the strong pinning limit relevant for iron-based superconductors at low magnetic fields are considered. It is found that in the more anisotropic materials, such as SmFeAsO and NdFeAsO, the field-angular dependence is completely dominated by the coherence-length (upper-critical field) anisotropy, thereby explaining recent results on the critical current in these materials. In less anisotropic superconductors, strong pinning can lead to an apparent inversion of the anisotropy. Finally, it is shown that, under all circumstances, the ratio of c-axis and ab-plane critical current densities for magnetic field along the ab-plane directly yields the coherence length anisotropy factor εξ.

description: Climate change and our increasing population threatens the availability of sustainable food sources, creating greater pressure to find solutions. Increasing crop yield can mitigate these problems. Given that seeds are the most important agronomic trait, a key component of this reproductive success is pollination. The pollination pathway, both compatible and self-incompatible (SI), is comprised of complex signalling mechanisms which govern pollen-pistil communications. Even with significant contributions to our understanding of the pollination response through the identification of key players and its signalling mechanism, there remains a gap in our understanding of the SI pathway.Although kinase-associated protein phosphatase (KAPP) can interact in vitro with various receptor kinases, for decades, its specific role in SI remained unknown. In this study, biochemical approaches determined that KAPP was highly expressed in mature stigmas with poor expression in pollen. While compatible pollen did not affect KAPP levels, following SI pollination, KAPP levels were significantly increased. Through transgenic approaches, overexpressing only the phosphatase type 2C (PP2C) domain of KAPP sufficiently reduced pollen acceptance, leading to shorter pods and reduced seed production. These observations indicate that KAPP could be a positive regulator in the incompatibility response where it acts through its PP2C domain.When a PP2C domain mutated in the mitogen-activated protein kinase (MAPK) docking site (KAPP?290M) was overexpressed, a more compatible phenotype relative to PP2C overexpression was observed in the KAPP?290M transgenic lines. However, biochemical analysis revealed that this phenotype was not due to the inability of the KAPP?290M to dephosphorylate MPK4 as the mutated version KAPP?290M was able to effectively dephosphorylate MPK4 in vitro. Confocal imaging of KAPP?290M-RFP expression indicated that, lack of these key MAPK docking residues resulted in localization of KAPP?290M-RFP from the cytosol to the plasma membrane. Collectively, in this study, I have identified KAPP as a positive regulator of SI acting through its PP2C domain and provided evidence for the requirement of the MAPK docking site for precise intracellular localization. Therefore, this study bridges the knowledge gap in SI and provides another protein which can be manipulated to create novel hybrids to improve crop yield.

description: We answer in the affirmative a question posed by Ivanov and Vassilev on the existence of a seven dimensional quaternionic contact manifold with closed fundamental 4-form and non-vanishing torsion endomorphism. Moreover, we show an approach to the classification of seven dimensional solvable Lie groups having an integrable left invariant quaternionic contact structure. In particular, we prove that the unique seven dimensional nilpotent Lie group admitting such a structure is the quaternionic Heisenberg group.

Recurrent miscarriage : unraveling the complex etiology
Creators: name: Hanna, Courtney Wood
Publisher: name: University of British Columbia

description: Recurrent miscarriage (RM), defined as 3 or more consecutive spontaneous losses of pregnancy before 20 weeks gestation, affects 1-2% of couples and has a complex etiology. Half of miscarriages from RM cases are caused by chromosomal abnormalities in the embryo and while there are several associated maternal factors, underlying causes and clinically relevant biomarkers have been elusive. I hypothesized that genetic and/or epigenetic factors associated with maternal meiotic non-disjunction, reproductive aging and endocrinological profile, or placental functioning will contribute to the etiology of RM. In these case-control studies, I investigated the association between RM and 1) maternal mutations in synaptonemal complex protein 3 (SYCP3), 2) maternal telomere lengths, 3) maternal polymorphisms in genes in the hypothalamus-pituitary-ovarian (HPO) axis and 4) placental DNA methylation patterns. The findings suggest that maternal mutations in SYCP3 and polymorphisms in HPO axis genes may not contribute significantly to risk for RM. No mutations in SYCP3 were identified in women with RM with at least one trisomic conception. While associations between polymorphisms within the estrogen receptor β, activin receptor 1, prolactin receptor and glucocorticoid receptor genes and RM were identified, these were not significant after correction for multiple comparisons. Aspects of chromosomal biology may be important factors in the etiology of RM. Women with RM had significantly shorter telomeres compared to controls, suggesting altered rates of biological aging. In the placental villi of RM samples, there were few differences in DNA methylation at targeted sites when compared to isolated miscarriages and elective terminations. However, gene ontology analysis showed that imprinted genes and immune response pathways were overrepresented among those sites differentially methylated between RM and elective termination placentas. The RM group additionally had an increase in the number of outlier cases at a select number of imprinted loci. Furthermore, several placental samples from both cases and controls showed aberrant DNA methylation profiles at many loci investigated, suggesting these samples may have global dysregulation of DNA methylation and/or differences in placental composition/functioning. These studies have improved our understanding of mechanisms involved in RM and will contribute to the direction of future research.
Curvature-direction measures of self-similar sets

description: We obtain fractal Lipschitz-Killing curvature-direction measures for a large class of self-similar sets F in R^d. Such measures jointly describe the distribution of normal vectors and localize curvature by analogues of the higher order mean curvatures of differentiable submanifolds. They decouple as independent products of the unit Hausdorff measure on F and a self-similar fibre measure on the sphere, which can be computed by an integral formula. The corresponding local density approach uses an ergodic dynamical system formed by extending the code space shift by a subgroup of the orthogonal group. We then give a remarkably simple proof for the resulting measure version under minimal assumptions.

Attending to the Needs of Newcomer Youth: A Collective Case Study of School Integration

description: In recent years, scholars have been calling for more innovative research in the area of immigration. Specifically, they are challenging the common acculturation strategies often used to describe the experiences of newcomer youth. Newcomer youth themselves have described school as a primary arena influencing their post-migration experiences. However, comprehensive reports continue to reveal unjust educational practices that place newcomer youth at risk of school disengagement. In response, this body of work focuses on the phenomenon of school integration. School integration represents a new point of entry to explore the adjustment of newcomer youth across all aspects of student life. This includes language acquisition, academic performance, classroom behaviour, social networking, identity negotiation, emotional and familial well-being, involvement in school life, and understanding of the academic system.A social constructionist epistemology, incorporating an integrated social justice lens, guided a collective case study within a single high school in Alberta. This inquiry was guided by the following overarching research question: How do participants perceive and describe newcomer youths’ experiences integrating into high school? Consisting of three manuscripts, this dissertation critically explores the experiences of three stakeholder groups (i.e., newcomer students, teachers, and service providers), with the aim of systematically weaving together a more holistic narrative of the factors impacting school integration.Manuscript 1 highlights the voices and experiences of 13 newcomer youth who entered high school in Alberta and offers insight into the triumphs and perils they face within a singular high school setting. Manuscript 2 explores the perspectives of eight teachers who support newcomer students in their daily practices, three of whom teach English as an Additional Language (EAL) courses. Finally, Manuscript 3 centres on the perspectives of six services providers, including a vice principal, school guidance counsellors, settlement workers, and an at-risk youth coordinator.Taken together, the findings from the case study complement traditional immigration frameworks and offer systemic solutions to help improve the social, emotional, and academic transitions of newcomer youth as they enter a new school system. It pushes beyond multicultural initiatives and strives towards more socially just research, training, policies, and practices.
Forward-backward correlations and charged-particle azimuthal distributions in pp interactions using the ATLAS detector

description: Using inelastic proton-proton interactions at sqrt(s) = 900 GeV and 7 TeV, recorded by the ATLAS detector at the LHC, measurements have been made of the correlations between forward and backward charged-particle multiplicities and, for the first time, between forward and backward charged-particle summed transverse momentum. In addition, jet-like structure in the events is studied by means of azimuthal distributions of charged particles relative to the charged particle with highest transverse momentum in a selected kinematic region of the event. The results are compared with predictions from tunes of the PYTHIA and HERWIG++ Monte Carlo generators, which in most cases are found to provide a reasonable description of the data.

“L’écomusée n’est pas musée”. Gli ecomusei come laboratori produttori di cultura, territorio e relazione

description: In presenting a current project for the implementation of a Landscape Ecomuseum in the Palestinian village of Battir, in West bank, the article explores some aspects of the history and of the theoretical and methodological framework of ecomuseums as emerged within the French movement of the Nouvelle Muséographie from the 1960s, together with other forms of alternative museographical strategies. At the core of the movement – moved by the ambition of starting a process of democratisation of the museal institutions and functions – there were three main ideas: a new conception of heritage, enlarged to encompass all the expressions of human culture and the notions of territory, community and local identity; the need of dispersing the walls of the majority museum to diffuse it on the territory and in the community; a perspective on museums as active engines in the productive process of cultural and social capital, rather than displays of representative projects generated by extra-local hegemonic powers. In rapport to other forms of alternative museums, the ecomuseum, despite representing an intrinsically polymorphous and evolutive reality encompassing a variety of different experiences, is characterised for its central reference and attention to the local dimension, at the environmental, socio-cultural and anthropological level. Rooted in a given territory and designed and animated with the participation of its inhabitants, each ecomuseum is unique since based on the safeguarding and valorisation of a specific social and geographical milieu. In the context of Battir village, characterised by many outstanding traits at the historical, anthropological and landscape level but threatened by the disruptive effects of the Israeli occupation and an ongoing conflict, an ecomuseum of landscape constitutes an important virtuous opportunity for resisting to the destruction of the territory and of the community by promoting and protecting what can be considered a world heritage and a set of shared universal values.
