description: Orofacial clefts [cleft lip (CL), cleft palate (CP), and cleft lip and palate (CLP)] are the most common orofacial congenital malformations found among live births, accounting for 65% of all head and neck anomalies. Due to conflicting information on the epidemiology of cleft deformities in African populations, this study was conducted to describe the epidemiology and patterns of orofacial clefts in Tanzania. This thesis also identified and described aspects of facial shape that vary most among normal population of children and between different ethnicities. The established baseline data for normal facial shape variation that can serve as phenotypic basis in genetic association studies to identify genes for orofacial clefts. Lastly, we also compared facial shape between noncleft children and children with repaired/unrepaired orofacial cleft in order to identify aspects of facial shape that differ most. In order to describe the epidemiology of orofacial clefts, a hospital-based retrospective descriptive study was conducted to identify all children with the disease attended or treated from 2004 to 2009. Comparison of facial shape in the general population and in individuals with orofacial clefts was carried using three-dimensional imaging system in combination with geometric morphometric analysis techniques. Isolated cleft lip was found to be the most common cleft type, followed by clefts of both the lip and palate, a pattern broadly similar to other series in African countries, and different from the distribution of orofacial clefts in low and middle income countries in other parts of the world. We also found a significant face shape differences within the population of normal Tanzanian children that were localized to specific regions of the face. Some of these facial shape differences manifested in ethnic-specific manner. Facial shape in noncleft children was also found to be significantly different from both children with repaired and unrepaired orofacial clefts of the same sex, age and ethnic group. Facial phenotypes that have been identified both in the general population and in affected individuals in this study might be used in genetic association and linkage analyses to identify risk markers for orofacial clefting.
Géographie des confins : espace et littérature chez Pierre Morency, Pierre Nepveu et Louis Hamelin

description: Cette étude interroge les différentes relations que la littérature québécoise contemporaine noue avec l’espace, et particulièrement les lieux de confins que rien ne semble prédisposer à une entrée en littérature : la campagne, la forêt, la petite ville et le Nord. Peu de recherches ont été menées sur ce que représentent ces espaces dans l’imaginaire contemporain. Ce sujet est d’autant plus crucial en littérature québécoise que ces “provinces littéraires” sont associées à des idéologies passéistes héritées de l’histoire littéraire du Québec (la “littérature du terroir”). Comment le poète et naturaliste Pierre Morency (1942-), le romancier Louis Hamelin (1959-) et l’écrivain et essayiste Pierre Nepveu (1945-) prennent en compte cet héritage pour écrire ces confins qui, depuis le début du XXe siècle, subissent de profonds changements ? L’étude s’attache à montrer comment s’élabore une vie intellectuelle qui permet au sujet d’adopter une attitude réflexive propice à l’écriture. Le premier chapitre expose après Beaudoin et Morency en quoi la question de la représentation de l’espace est problématique dans l’histoire littéraire québécoise. Dans le sillage des travaux de Genette, le second chapitre envisage le livre et le texte comme des espaces matériels. Un troisième chapitre étudie la description (Hamon) de quelques paysages privilégiés (Roger). Le dernier chapitre montre comment l’écriture des confins interroge la subjectivité en adoptant une perspective qui combine les approches philosophique (Heidegger), psychanalytique (Anzieu) et esthétique (Simard-Laflamme). La réflexion s’ouvre sur une mise en relation de ces textes avec le discours écologique contemporain.

description: Large cross-section GaN waveguides are proposed as a suitable architecture to achieve integrated quantum photonic circuits. Directional couplers with this geometry have been designed with aid of the beam propagation method and fabricated using inductively coupled plasma etching. Scanning electron microscopy inspection shows high quality facets for end coupling and a well defined gap between rib pairs in the coupling region. Optical characterization at 800 nm shows single-mode operation and coupling-length-dependent splitting ratios. Two photon interference of degenerate photon pairs has been observed in the directional coupler by measurement of the Hong-Ou-Mandel dip with 96% visibility.

description: Gated variable resistors were manufactured by depositing epitaxial heterostructures of doped La_{2}CuO_{4} and SrTiO_{3} layers. Their conductance change as function of write current I and write time t followed a simple empirical law of the form ΔG/G = CI^A t^B. This behavior is in agreement with ionic transport that accelerates exponentially with electrical field strength.

description: The Energy and Momentum Conceptual Survey (EMCS) is a multiple-choice survey that contains conceptual problems involving a variety of energy and momentum concepts covered in a typical introductory physics course for science and engineering majors. Prior studies suggest that many concepts on the survey are challenging for introductory physics students and the average student scores after traditional lecture-based instruction are low. The research presented here investigates the progression in student understanding of the EMCS concepts including their evolution from the beginning to the end of their courses in introductory and advanced level undergraduate physics after traditional lecture-based instruction. We find that on all EMCS questions on which less than 50% of the introductory physics students answered a question correctly after traditional instruction, less than two-thirds of the upper-level undergraduate students provided the correct response after traditional lecture-based instruction. We discuss the EMCS questions that remain challenging and the common alternate conceptions among upper-level students. The findings presented here are consistent with prior research showing that traditional instruction in upper-level courses, which typically focuses primarily on quantitative problem solving and often incentivizes use of algorithmic approaches, is not effective for helping many students develop a functional understanding of underlying concepts.

description: This paper presents a simple, self-supervised method for magnifying subtle motions in video: given an input video and a magnification factor, we manipulate the video such that its new optical flow is scaled by the desired amount. To train our model, we propose a loss function that estimates the optical flow of the generated video and penalizes how far if deviates from the given magnification factor. Thus, training involves differentiating through a pretrained optical flow network. Since our model is self-supervised, we can further improve its performance through test-time adaptation, by finetuning it on the input video. It can also be easily extended to magnify the motions of only user-selected objects. Our approach avoids the need for synthetic magnification datasets that have been used to train prior learning-based approaches. Instead, it leverages the existing capabilities of off-the-shelf motion estimators. We demonstrate the effectiveness of our method through evaluations of both visual quality and quantitative metrics on a range of real-world and synthetic videos, and we show our method works for both supervised and unsupervised optical flow methods.

description: We study pre-equilibrium giant dipole resonance excitation and fusion in the neutron-rich system $^{132}$Sn+$^{48}$Ca at energies near the Coulomb barrier, and we compare photon yields and total fusion cross sections to those of the stable system $^{124}$Sn+$^{40}$Ca. The dynamic microscopic calculations are carried out on a three-dimensional lattice using both the Time-Dependent Hartree-Fock method and the Density Constrained TDHF method. We demonstrate that the peak of the GDR excitation spectrum occurs at a substantially lower energy than expected for an equilibrated system, thus reflecting the very large prolate elongation of the dinuclear complex during the early stages of fusion. Our theoretical fusion cross-sections for both systems agree reasonably well with recent data measured at HRIBF.

description: We consider axial torsion fields which appear in higher derivative quantum gravity. It is shown, in general, that the torsion field possesses states with two spins, one and zero, with different masses. The first-order formulation of torsion fields is performed. Projection operators extracting pure spin and mass states are given. We obtain the Lagrangian in the framework of the first order formalism and energy-momentum tensor. The effective interaction of torsion fields with electromagnetic fields is discussed. The Hamiltonian form of the first order torsion field equation is given.

description: The inclusive reactions $pp \rightarrow e^+ e^- X$ and $np \rightarrow e^+ e^- X$ at the laboratory kinetic energy of 1.25 GeV are investigated in a model of dominance of nucleon and $Δ$ resonances. Experimental data for these reactions have recently been reported by the HADES Collaboration. In the original model, the dileptons are produced either from the decays of nucleon and $Δ$ resonances $R \rightarrow N e^+ e^-$ or from the Dalitz decays of $π^0$- and $η$-mesons created in the $R \to Nπ^0$ and $R \to Nη$ decays. We found that the distribution of dilepton invariant masses in the $pp \rightarrow e^+ e^- X$ reaction is well reproduced by the contributions of $R \rightarrow N e^+ e^-$ decays and $R \rightarrow N π^0$, $π^0 \to γe^+e^-$ decays. Among the resonances, the predominant contribution comes from the $Δ(1232)$, which determines both the direct decay channel $R \rightarrow N e^+ e^-$ and the pion decay channel. In the collisions $np \rightarrow e^+ e^- X$, additional significant contributions arise from the $η$-meson Dalitz decays, produced in the $np \rightarrow npη$ and $np \rightarrow dη$ reactions, the radiative capture $np \rightarrow d e^+ e^-$, and the $np \rightarrow np e^+ e^-$ bremsstrahlung. These mechanisms may partly explain the strong excess of dileptons in the cross section for collisions of $np$ versus $pp$, which ranges from 7 to 100 times for the dilepton invariant masses of 0.2 to 0.5 GeV.

description: The elastic scattering of an atomic nucleus plays a central role in dark matter direct detection experiments. In those experiments, it is usually assumed that the atomic electrons around the nucleus of the target material immediately follow the motion of the recoil nucleus. In reality, however, it takes some time for the electrons to catch up, which results in ionization and excitation of the atoms. In previous studies, those effects are taken into account by using the so-called Migdal's approach, in which the final state ionization/excitation are treated separately from the nuclear recoil. In this paper, we reformulate the Migdal's approach so that the "atomic recoil" cross section is obtained coherently, where we make transparent the energy-momentum conservation and the probability conservation. We show that the final state ionization/excitation can enhance the detectability of rather light dark matter in the GeV mass range via the {\it nuclear} scattering. We also discuss the coherent neutrino-nucleus scattering, where the same effects are expected.

description: We have used deep GALEX observations at the infall region of the Coma cluster to measure the faintest UV luminosity functions (LFs) presented for a rich galaxy cluster thus far. The Coma UV LFs are measured to M_UV = -10.5 in the GALEX FUV and NUV bands, or 3.5 mag fainter than previous studies, and reach the dwarf early-type galaxy population in Coma for the first time. The Schechter faint-end slopes (alpha = -1.39 in both GALEX bands) are shallower than reported in previous Coma UV LF studies owing to a flatter LF at faint magnitudes. A Gaussian-plus-Schechter model provides a slightly better parametrization of the UV LFs resulting in a faint-end slope of ~ -1.15 in both GALEX bands. The two-component model gives faint-end slopes shallower than -1 (a turnover) for the LFs constructed separately for passive and star forming galaxies. The UV LFs for star forming galaxies show a turnover at M_UV ~ -14 owing to a deficit of dwarf star forming galaxies in Coma with stellar masses below M*=10^8 Msun. A similar turnover is identified in recent UV LFs measured for the Virgo cluster suggesting this may be a common feature of local galaxy clusters, whereas the field UV LFs continue to rise at faint magnitudes. We did not identify an excess of passive galaxies as would be expected if the missing dwarf star forming galaxies were quenched inside the cluster. In fact, the LFs for both dwarf passive and star forming galaxies show the same turnover at faint magnitudes. We discuss the possible origin of the missing dwarf star forming galaxies in Coma and their expected properties based on comparisons to local field galaxies.

description: The covariant canonical transformation theory applied to the relativistic Hamiltonian theory of classical matter fields in dynamical space-time yields a novel (first order) gauge field theory of gravitation. The emerging field equations necessarily embrace a quadratic Riemann term added to Einstein's linear equation. The quadratic term endows space-time with inertia generating a dynamic response of the space-time geometry to deformations relative to (Anti) de Sitter geometry. A "deformation parameter" is identified, the inverse dimensionless coupling constant governing the relative strength of the quadratic invariant in the Hamiltonian, and directly observable via the deceleration parameter $q_0$. The quadratic invariant makes the system inconsistent with Einstein's constant cosmological term, $Λ= \mathrm{const}$. In the Friedman model this inconsistency is resolved with the scaling ansatz of a "cosmological function", $Λ(a)$, where $a$ is the scale parameter of the FLRW metric. %Moreover, the strain generated by the quadratic term turns out to act as a geometrical stress. The cosmological function can be normalized such that with the $Λ$ CDM parameter set the present-day observables, the Hubble constant and the deceleration parameter, can be reproduced. %We analyze the asymptotics of the such normalized Friedman equations with respect to both, the fundamental parameters (coupling constants) and the scale $a$. With this parameter set we recover the dark energy scenario in the late epoch. The proof that inflation in the early phase is caused by the "geometrical fluid" representing the inertia of space-time is yet pending, though.

We demonstrate that at one-loop level the masses for particle and antiparticle remain equal due to Lorentz symmetry only. An inequality of masses implies breaking of the Lorentz invariance and non-conservation of the usually conserved charges.

description: This thesis examines the Women Writers' Club and the significant contribution of women writers to Irish literary and print culture during the period 1930-1960. It reveals a network of female writers and publishers who influenced the production and reception of texts and the affiliations which shaped contemporary cultural practices. As illustrated in my ‘Web of Women Writers’, these associative networks connected diverse female authors and facilitated their engagement with important social and political issues. The women authors who formed the membership of the Women Writers’ Club established a ‘Book of the Year’ award. This literary prize generated a corpus of women’s writing, a compilation of a rich body of work which reflected the ethos of this women-centred club. Furthermore, my thesis examines the leading role which women writers played in mainstream and periodical publishing. Using a case history approach, I offer the first full account of the feminist private printing press, The Gayfield Press, assessing critically the aesthetic vision of its owners. I also consider the social and political coding within the texts it produced. In addition to discussing publishing practices, my thesis also considers the reading practices of a dissident cultural elite through a case history study of an intellectual woman of the period. Finally, this thesis contextualizes the Women Writers’ Club within a broader artistic milieu which includes the United Arts Club, Irish P.E.N and the Irish Academy of Letters. It also offers the first account of Irish P.E.N and the role of women writers within this club. In conclusion, this thesis challenges the notion of a hegemonic male?dominated literary scene, opens up new avenues for investigation into the role of cultural clubs in Irish history and offers a fresh perspective on women writers in Ireland in the mid-twentieth century.

description: The localization of one-electron states in the large (but finite) disorder limit is investigated. The inverse participation number shows a non--monotonic behavior as a function of energy owing to anomalous behavior of few-site localization. The two-site approximation is solved analytically and shown to capture the essential features found in numerical simulations on one-, two- and three-dimensional systems. Further improvement has been obtained by solving a three-site model.

description: We provide the notion of entropy for a classical Klein-Gordon real wave, that we derive as particular case of a notion entropy for a vector in a Hilbert space with respect to a real linear subspace. We then consider a localised automorphism on the Rindler spacetime, in the context of a free neutral Quantum Field Theory, that is associated with a second quantised wave, and we explicitly compute its entropy $S$, that turns out to be given by the entropy of the associated classical wave. Here $S$ is defined as the relative entropy between the Rindler vacuum state and the corresponding sector state (coherent state). By $λ$-translating the Rindler spacetime into itself along the upper null horizon, we study the behaviour of the corresponding entropy $S(λ)$. In particular, we show that the QNEC inequality in the form $\frac{d^2}{dλ^2}S(λ)\geq 0$ holds true for coherent states, because $\frac{d^2}{dλ^2}S(λ)$ is the integral along the space horizon of a manifestly non-negative quantity, the component of the stress-energy tensor in the null upper horizon direction.

description: 153Eu3+:Y2SiO5 is a very attractive candidate for a long lived, multimode quantum memory due to the long spin coherence time (~15 ms), the relatively large hyperfine splitting (100 MHz) and the narrow optical homogeneous linewidth (~100 Hz). Here we show an atomic frequency comb memory with spin wave storage in a promising material 153Eu3+:Y2SiO5, reaching storage times slightly beyond 10 μs. We analyze the efficiency of the storage process and discuss ways of improving it. We also measure the inhomogeneous spin linewidth of 153Eu3+:Y2SiO5, which we find to be 69 \pm 3 kHz. These results represent a further step towards realising a long lived multi mode solid state quantum memory.

description: In order to realistically simulate the interaction of a femtosecond laser pulse with a nanometre-thick target it is necessary to consider a target preplasma formation due to the nanosecond long amplified-spontaneous-emission pedestal and/or prepulse. The relatively long interaction time dictated that hydrodynamic simulations should be employed to predict the target particles' number density distributions prior the arrival of the main laser pulse. By using the output of the hydrodynamic simulations as input into particle-in-cell simulations, a detailed understanding of the complete laser-foil interaction is achieved. Once the laser pulse interacts with the preplasma it deposits a fraction of its energy on the target, before it is either reflected from the critical density surface or transmitted through an underdense plasma channel. A fraction of hot electrons is ejected from the target leaving the foil in a net positive potential, which in turn results in proton and heavy ion ejection. In this work protons reaching ~25 MeV are predicted for a laser of ~40 TW peak power and ~600 MeV are expected from a ~4 PW laser system.

description: We present the results of several multi-station Very Long Baseline Interferometry (VLBI) experiments conducted with the ESA spacecraft Venus Express as a target. To determine the true capabilities of VLBI tracking for future planetary missions in the solar system, it is necessary to demonstrate the accuracy of the method for existing operational spacecraft. We describe the software pipeline for the processing of phase referencing near-field VLBI observations and present results of the ESA Venus Express spacecraft observing campaign conducted in 2010-2011. We show that a highly accurate determination of spacecraft state-vectors is achievable with our method. The consistency of the positions indicates that an internal rms accuracy of 0.1 mas has been achieved. However, systematic effects produce offsets up to 1 mas, but can be reduced by better modelling of the troposphere and ionosphere and closer target-calibrator configurations.

description: Quaternion-valued solutions to the non-commutative KdV equation are produced using determinants. The solutions produced in this way are (breather) soliton solutions, rational solutions, spatially periodic solutions and hybrids of these three basic types. A complete characterization of the parameters that lead to non-singular 1-soliton and periodic solutions is given. Surprisingly, it is shown that such solutions are never singular when the solution is essentially non-commutative. When a 1-soliton solution is combined with another solution through an iterated Darboux transformation, the result behaves asymptotically like a combination of different solutions. This ``non-linear superposition principle'' is used to find a formula for the phase shift in the general 2-soliton interaction. A concluding section compares these results with other research on non-commutative soliton equations and lists some open questions.

description: The growing importance of microfluidic and nanofluidic devices to the study of biological processes has highlighted the need to better understand how confinement affects the behavior of polymers in flow. In this paper we explore one aspect of this question by calculating the steady-state extension of a long polymer chain in a narrow capillary tube in the presence of simple shear. The calculation is carried out within the framework of the Rouse-Zimm approach to chain dynamics, using a variant of a nonlinear elastic model to enforce finite extensibility. Under the assumption that the sole effect of the confining surface is to modify the pre-averaged hydrodynamic interaction, we find that the calculated fractional chain extension x is considerably smaller than its value in the bulk. Furthermore, the variation of x with a dimensionless shear rate (the Weissenberg number, Wi) is in good qualitative agreement with data from experiments on the flow-induced stretching of lambda- phage DNA near a non-adsorbing glass surface.

description: The Numerical INJection Analysis (NINJA) project is a collaborative effort between members of the numerical relativity and gravitational wave data analysis communities. The purpose of NINJA is to study the sensitivity of existing gravitational-wave search and parameter-estimation algorithms using numerically generated waveforms, and to foster closer collaboration between the numerical relativity and data analysis communities. The first NINJA project used only a small number of injections of short numerical-relativity waveforms, which limited its ability to draw quantitative conclusions. The goal of the NINJA-2 project is to overcome these limitations with long post-Newtonian - numerical relativity hybrid waveforms, large numbers of injections, and the use of real detector data. We report on the submission requirements for the NINJA-2 project and the construction of the waveform catalog. Eight numerical relativity groups have contributed 63 hybrid waveforms consisting of a numerical portion modelling the late inspiral, merger, and ringdown stitched to a post-Newtonian portion modelling the early inspiral. We summarize the techniques used by each group in constructing their submissions. We also report on the procedures used to validate these submissions, including examination in the time and frequency domains and comparisons of waveforms from different groups against each other. These procedures have so far considered only the $(\ell,m)=(2,2)$ mode. Based on these studies we judge that the hybrid waveforms are suitable for NINJA-2 studies. We note some of the plans for these investigations.

Identification of metastasis-associated genes in prostate cancer

description: Metastasis is thought to be based on genetic and epigenetic alterations. The mechanisms underlying prostate cancer metastasis are not clear. Studies aimed at identifying genes with key roles in this process have been impeded by lack of clinically relevant models. The heterogeneity of primary prostate cancer specimens from patients, consisting of non-metastatic and metastatic subpopulations, hampers identification of metastasis-associated genes by direct comparison of primary and secondary cancers. To overcome such hurdles, metastatic and non-metastatic tumor sublines have been developed from one patient’s primary prostate cancer specimen using subrenal capsule grafting into NOD-SCID mice. Chromosomal alterations present in the metastatic subline, but not in non-metastatic counterparts, were identified in a small percentage of cells in the parental tissue, suggesting that metastatic potential of primary cancers can be associated with a small cancer cell subpopulation. Sublines with different metastatic potential derived from same patient’s multifocal primary cancer provide valuable materials for identifying metastasis-associated genes and predictive markers. To identify metastasis-associated genes, differential gene expression analysis of metastatic PCa1-met and non-metastatic PCa2 prostate cancer sublines was carried out. Among various differentially expressed genes identified, ASAP1, a gene not previously associated with prostate cancer, was upregulated in the metastatic subline as confirmed by qRT-PCR and immunohistochemical staining. In clinical specimens, ASAP1 protein staining was elevated in 80% of primary prostate cancers and substantially higher in metastatic lesions compared to benign prostate tissue. Extra ASAP1 gene copies were detected in 58% of primary prostate cancer specimens. Increased ASAP1 protein expression was correlated with prostate cancer metastasis and PSA recurrence. siRNA- and shRNA-induced reduction of levels of ASAP1 protein markedly suppressed in vitro PC-3 cell migration, matrigel invasion and metastasis in vivo. These results indicate that ASAP1 plays an important role in prostate cancer invasion and metastasis and suggest that it provides a potential predictive marker and therapeutic target for the disease. Furthermore, the approach used to identify metastasis-associated genes by comparison of gene profiles of paired metastatic and non-metastatic sublines was validated. The subrenal capsule xenograft system provides a valuable platform for studying various aspects of prostate cancer metastasis.

description: We have analyzed Spitzer and NASA/IRTF 2 - 35 \mum spectra of the warm, ~350 K circumstellar dust around the nearby MS star η Corvi (F2V, 1.4 \pm 0.3 Gyr). The spectra show clear evidence for warm, water- and carbon-rich dust at ~3 AU from the central star, in the system's Terrestrial Habitability Zone. Spectral features due to ultra-primitive cometary material were found, in addition to features due to impact produced silica and high temperature carbonaceous phases. At least 9 x 10^18 kg of 0.1 - 100 \mum warm dust is present in a collisional equilibrium distribution with dn/da ~ a^-3.5, the equivalent of a 130 km radius KBO of 1.0 g/cm^3 density and similar to recent estimates of the mass delivered to the Earth at 0.6 - 0.8 Gyr during the Late Heavy Bombardment. We conclude that the parent body was a Kuiper-Belt body or bodies which captured a large amount of early primitive material in the first Myrs of the system's lifetime and preserved it in deep freeze at ~150 AU. At ~1.4 Gyr they were prompted by dynamical stirring of their parent Kuiper Belt into spiraling into the inner system, eventually colliding at 5-10 km/sec with a rocky planetary body of mass \leq MEarth at ~3 AU, delivering large amounts of water (>0.1% of MEarth's Oceans) and carbon-rich material. The Spitzer spectrum also closely matches spectra reported for the Ureilite meteorites of the Sudan Almahata Sitta fall in 2008, suggesting that one of the Ureilite parent bodies was a KBO.
