Some aspects of thyroid metabolism in the chicken
Creators: name: Poon, Raymond Wai-Man
Publisher: name: University of British Columbia
Year: 2010

description: The study of thyroid metabolism usually involves the employment of antithyroid compounds and exogenous thyroid hormones in order to elucidate the thyroid function through the understanding of the effects of these compounds. In this study, the effects of die thiouracil and rapeseed meal goitrogens were examined in chicks. The goitrogenic effects of the thiouracil were manifested rapidly by increased thyroid weight, thyroid epithelium and uptake of radioiodine. The goitrogenic effects of rapeseed meal were similar to the effect of thiouracil except that at the level of meal fed, the effects were less pronounced and evident only after prolonged feeding. When an iodine deficient diet was fed to growing chicks, the goitrogenic effect was less than when thiouracil or rapeseed meal was fed. Histological studies of the thyroid glands of adult birds fed an iodine deficient diet showed slight hyperplasia without thyroidal enlargement and with persistence of colloid,whereas growing chicks fed an iodine deficient diet displayed severe hyperplasia and loss of colloid. By contrast, the effects of thiouracil were independent of the age of chicks. A combination of thiouracil and rapeseed meal produced goitrogenic effects greater than those occurring when thiouracil or rapeseed meal was fed singly. Thiouracil fed in an iodine deficient diet, on the other hand, showed no goitrogenicity for chicks. High doses (4.0 μg) of thyroxine administered daily to thiouraci1-treated chicks alleviated the antithyroid effects of thiouracil as indicated by the decrease in thyroid weight, thyroid epithelium and radioiodine uptake. Low doses (1.0 ug or less) of thyroxine administration, however, produced the opposite effects. Nevertheless, high doses of thyroxine did not relieve the growth depressing effects of thiouracil completely. Autoradiographic studies on thyroids of thiouraci1-treated or rapeseed meal-fed chicks showed a uniform distribution of radioiodine in the colloid within five hours of administration of tracer. Differences in activity were observed among the individual follicles in each gland. The smaller follicles concentrated more iodine than the larger ones. Furthermore, very little iodine was observed in the epithelial cells. These findings, together with previous reports that inorganic iodine was present in the thyroid after its administration, suggested that iodination did not occur in the apical membrane of the follicular cells bordering the colloid. Different rapeseed cultivars contain different amounts of glucosinolates which are responsible for the goitrogenic effect of the rapeseed meal. Goitrogenicity of three different kinds of rapeseed meals was compared in growing chicks and the results indicated that Candle meal had the least goitrogenic activity than the Tower and Span meal.

description: La presente dissertazione si pone come oggetto di analisi la produzione poetica di Robert Kroetsch (1927-2011), scrittore e critico letterario canadese nativo dell’Alberta (Canada), che tra il 1960 e il 2010 ha pubblicato un numero notevole di opere (nove romanzi, più di venti opere poetiche tra componimenti singoli e in raccolta, due volumi di saggi e diverse interviste). In particolare si è scelto di focalizzare l’attenzione sulle ultime tre raccolte di poesia – rispettivamente The Hornbooks of Rita K (2001), The Snowbird Poems (2004) e Too Bad: Sketches Toward a Self-Portrait (2010) – che, se confrontate con la produzione precedente, forniscono prova di alcuni elementi di novità all’interno della prospettiva poetica di Kroetsch. L’ipotesi dalla quale trae origine il presente studio è infatti che, a partire dalla raccolta The Hornbooks of Rita K, Kroetsch abbia imboccato un percorso di evoluzione stilistica che corre in parallelo con la formulazione di una nuova poetica. Nello specifico, si osserva che, negli ultimi dieci anni, da un punto di vista formale i componimenti si frammentano progressivamente, passando da una forma lunga – quella del long poem – a una breve – lo sketch, che risulta più adatta a rappresentare sul piano espressivo una mutata percezione dell’Io poetico. A un simile aspetto si aggiunge poi il fatto che la raffigurazione della propria vicenda umana diventa, con sempre maggiore evidenza, motivo di riflessione su una condizione universale dell’umano e sulla dimensione etica del suo agire.
description: The core of my research concerns the poetic production of the english-canadian writer Robert Kroetsch, who has been defined “Mr Canadian Postmodern” (Linda Hutcheon) for having introduced the postmodern sensibility in his own country both with some fundamental critical essays and with a number of poetic and narrative masterpieces. The dissertation focuses on poetry, especially on three collections of poems (The Hornbooks of Rita K, The Snowbird Poems and Too Bad: Sketches Toward a Self-Portrait), which have been published in the last ten years, i.e. between 2001 and 2010. The most recent pieces of poetry,  formally fragmented into sketches, can be in fact described as an attempt to portray the real as well as the author’s fragmented and ineffable Self. The result is what Kroetsch’s friend and poet Fred Wah defined “a labyrinth of possibilities”, thus opening itself to a “poetics of process”, an ongoing approach to a description of life and of the Self. In the opening epigraph of the latest collection one reads: “A disclaimer: This book is not an autobiography. It is a gesture toward a self-portrait, which I take to be quite a different kettle of fish”. This is what my research also wishes to be, a gesture, not a fixing of an imagery or a poetics, but a reading proposal, one in the “labyrinth of possibilities”.

description: Introductions of non-native species (NNS) are major drivers of biodiversity loss. Gammarids (Crustacea, Gammaroidea) have been particularly successful in establishing and spreading in their non-native range, especially in Europe. While their impacts are wide-ranging, interference competition with native species has received limited study to date. Here, we assessed the competitive abilities of the successful North American NNS Gammarus tigrinus relative to the European native Gammarus duebeni, over a chironomid larva as a single food resource. We staged four types of dyadic contest encounters, with individuals of the native or NNS added to the experimental arena containing the food resource, and inter- or intraspecific competitor individuals added upon the first individual taking possession of the resource, or after 20 minutes. Gammarus tigrinus were more likely to take hold of the bloodworm in the opening 20 minutes, and did so more quickly than G. duebeni. During this period, they were also less thigmotactic than the native, being more explorative and spending a smaller proportion of time in the outer zone of the arena. They exhibited more aggressive interactions and activity with increasing size and mass, whereas larger G. duebeni were shown to be less aggressive and less active. Gammarus tigrinus were found to be significantly less likely to lose possession to G. duebeni than they were to conspecifics, whereas G. duebeni were similarly likely to lose possession to G. tigrinus as to conspecifics. Overall, our findings indicate that the behaviour and competitive ability of G. tigrinus demonstrated here add to a list of traits that facilitate its invasion success. In addition, our method offers potential as an effective, standardisable means of assessing the competitive abilities of gammarid NNS. We encourage future studies to develop it further, incorporating alternative resources, such as habitat, and to assess the role of ecologically relevant abiotic stressors in determining contest outcomes.

description: An assignment map is a mathematical operator that describes initial system-environment states for open quantum systems. We reexamine the notion of assignments, introduced by Pechukas, and show the conditions assignments can account for correlations between the system and the environment, concluding that assignment maps can be made linear at the expense of positivity or consistency is more reasonable. We study the role of other conditions, such as consistency and positivity of the map, and show the effects of relaxing these. Finally, we establish a connection between the violation of positivity of linear assignments and the no-broadcasting theorem.

description: Here, we report a numerical implementation of the nonlocal homogenization approach recently proposed in [M. Silveirinha, Phys. Rev. B 75, 115104 (2007)], using the finite difference frequency-domain method to discretize the Maxwell-Equations. We apply the developed formalism to characterize the nonlocal dielectric function of several structured materials formed by dielectric and metallic particles, and in particular, we extract the local permittivity, permeability and magnetoelectric coupling parameters when these are meaningful. It is shown that the finite differences frequency domain implementation of the homogenization method is stable and robust, yielding very accurate results.

description: Visual emotion analysis (VEA) has attracted great attention recently, due to the increasing tendency of expressing and understanding emotions through images on social networks. Different from traditional vision tasks, VEA is inherently more challenging since it involves a much higher level of complexity and ambiguity in human cognitive process. Most of the existing methods adopt deep learning techniques to extract general features from the whole image, disregarding the specific features evoked by various emotional stimuli. Inspired by the \textit{Stimuli-Organism-Response (S-O-R)} emotion model in psychological theory, we proposed a stimuli-aware VEA method consisting of three stages, namely stimuli selection (S), feature extraction (O) and emotion prediction (R). First, specific emotional stimuli (i.e., color, object, face) are selected from images by employing the off-the-shelf tools. To the best of our knowledge, it is the first time to introduce stimuli selection process into VEA in an end-to-end network. Then, we design three specific networks, i.e., Global-Net, Semantic-Net and Expression-Net, to extract distinct emotional features from different stimuli simultaneously. Finally, benefiting from the inherent structure of Mikel's wheel, we design a novel hierarchical cross-entropy loss to distinguish hard false examples from easy ones in an emotion-specific manner. Experiments demonstrate that the proposed method consistently outperforms the state-of-the-art approaches on four public visual emotion datasets. Ablation study and visualizations further prove the validity and interpretability of our method.

Previously known examples are the "hyperkagome" and "kagome staircase". I give criteria in terms of loops for whether a given depleted lattice can order analogous to the kagome \sqrt{3} \times \sqrt{three} state, and also show how the pseudo-dipolar correlations (due to local constraints) generalize to even the random depleted case.

Subject-specific musculoskeletal models of the lower limbs for the prediction of skeletal loads during motion

Year: 2013
Subjects: ING-IND/34 Bioingegneria industriale

description: The determination of skeletal loading conditions in vivo and their relationship to the health of bone tissues, remain an open question. Computational modeling of the musculoskeletal system is the only practicable method providing a valuable approach to muscle and joint loading analyses, although crucial shortcomings limit the translation process of computational methods into the orthopedic and neurological practice. A growing attention focused on subject-specific modeling, particularly when pathological musculoskeletal conditions need to be studied. Nevertheless, subject-specific data cannot be always collected in the research and clinical practice, and there is a lack of efficient methods and frameworks for building models and incorporating them in simulations of motion.
The overall aim of the present PhD thesis was to introduce improvements to the state-of-the-art musculoskeletal modeling for the prediction of physiological muscle and joint loads during motion. A threefold goal was articulated as follows: (i) develop state-of-the art subject-specific models and analyze skeletal load predictions; (ii) analyze the sensitivity of model predictions to relevant musculotendon model parameters and kinematic uncertainties; (iii) design an efficient software framework simplifying the effort-intensive phases of subject-specific modeling pre-processing. 
The first goal underlined the relevance of subject-specific musculoskeletal modeling to determine physiological skeletal loads during gait, corroborating the choice of full subject-specific modeling for the analyses of pathological conditions. The second goal characterized the sensitivity of skeletal load predictions to major musculotendon parameters and kinematic uncertainties, and robust probabilistic methods were applied for methodological and clinical purposes. The last goal created an efficient software framework for subject-specific modeling and simulation, which is practical, user friendly and effort effective.
Future research development aims at the implementation of more accurate models describing lower-limb joint mechanics and musculotendon paths, and the assessment of an overall scenario of the crucial model parameters affecting the skeletal load predictions through probabilistic modeling.

description: The production of prompt photons is measured in the photoproduction regime of electron-proton scattering at HERA. The analysis is based on a data sample corresponding to a total integrated luminosity of 340 pb^-1 collected by the H1 experiment. Cross sections are measured for photons with transverse momentum and pseudorapidity in the range 6 < Et < 15 GeV and -1.0 < eta < 2.4, respectively. Cross sections for events with an additional jet are measured as a function of the transverse energy and pseudorapidity of the jet, and as a function of the fractional momenta x_gamma and x_p carried by the partons entering the hard scattering process. The correlation between the photon and the jet is also studied. The results are compared with QCD predictions based on the collinear and on the k_T factorisation approaches.

description: In this paper, we present HoloBoard, an interactive large-format pseudo-holographic display system for lecture-based classes. With its unique properties of immersive visual display and transparent screen, we designed and implemented a rich set of novel interaction techniques like immersive presentation, role-play, and lecturing behind the scene that is potentially valuable for lecturing in class. We conducted a controlled experimental study to compare a HoloBoard class with a normal class by measuring students' learning outcomes and three dimensions of engagement (i.e., behavioral, emotional, and cognitive engagement). We used pre-/post- knowledge tests and multimodal learning analytics to measure students' learning outcomes and learning experiences. Results indicated that the lecture-based class utilizing HoloBoard lead to slightly better learning outcomes and a significantly higher level of student engagement. Given the results, we discussed the impact of HoloBoard as an immersive media in the classroom setting and suggest several design implications for deploying HoloBoard in immersive teaching practices.

description: The self-interactions of gluons determine all the unique features of QCD and lead to a dominant abundance of gluons inside matter already at moderate $x$. Despite their dominant role, the properties of gluons remain largely unexplored. Tantalizing hints of saturated gluon densities have been found in $e$+p collisions at HERA, and in d+Au and Au+Au collisions at RHIC. Saturation physics will have a profound influence on heavy-ion collisions at the LHC. But unveiling the collective behavior of dense assemblies of gluons under conditions where their self-interactions dominate will require an Electron-Ion Collider (EIC): a new facility with capabilities well beyond those In this paper I outline the compelling physics case for $e$+A collisions at an EIC and discuss briefly the status of machine design concepts. of any existing accelerator.

description: Micro-bending is a well-known source of loss in optical waveguides. By treating the micro-bending as a stochastic process, the problem of loss mitigation can be modeled in terms of a Fokker-Planck equation. Given an initial refractive index profile, and taking micro-bending into account, we develop a formalism to derive a new refractive index profile which potentially results in less loss. Our formalism is based on applying the techniques of Supersymmetric Quantum Mechanics to a Fokker-Planck equation that is associated with a particular refractive index profile. We derive a non-linear differential equation, whose solutions determine whether an index profile can undergo a supersymmetric transformation that results in less loss. As an explicit example, we consider a monomial index profile. We show that there exists a range of values for the monomial exponent which results in the new index profile having less loss.

The scalar field has no self-interaction potential but a cosmological constant is included. Non-trivial solutions exist only when the cosmological constant is negative and the constant governing the coupling of the scalar field to the Ricci scalar curvature is positive. At least some of these solutions are stable when this coupling constant is not too large.

description: We have studied the correlation effects in Cs and Fr arising from the interplay of the residual Coulomb interaction to all orders and the neutral weak interaction which gives rise to the parity violating electric dipole transition to first order, within the framework of the relativistic coupled-cluster theory which circumvents the constrain of explicitly summing over the intermediate states. We observe that, the contributions arising from the perturbed doubly excited states are quite significant and hence, any calculation should not be considered accurate unless it includes the perturbed double excitations comprehensively. In this article, we have reported a comparative study of various results related to the parity violation in Cs and Fr.

description: The boundary energy - momentum tensors for a static observer in the conformally flat Rindler geometry are considered. We found the surface energy is positive far form the Planck world but the transversal pressures are negative. The kinematical parameters associated to a nongeodesic congruence of static observers are computed. The entropy $S$ corresponding to the degrees of freedom on the two surface of constant $ρ$ and $t$ equals the horizon entropy of a black hole with a time dependent mass and the Padmanabhan expression $E = 2 S T$ is obeyed. The two surface shear tensor is vanishing but the coefficient of the bulk viscosity $ζ$ is $1/16 π$ and therefore the negative pressure due to it acts as a surface tension.

description: Let X be the moduli space of SL(n,C), SU(n), GL(n,C), or U(n)-valued representations of a rank r free group. We classify the algebraic singular stratification of X. This comes down to showing that the singular locus corresponds exactly to reducible representations if there exist singularities at all. Then by relating algebraic singularities to topological singularities, we show the moduli spaces X generally are not topological manifolds, except for a few examples we explicitly describe.

description: It is shown that correlation function of the mean wind velocity generated by a turbulent thermal convection (Rayleigh number $Ra \sim 10^{11}$) exhibits exponential decay with a very long correlation time, while corresponding largest Lyapunov exponent is certainly positive. These results together with the reconstructed phase portrait indicate presence of chaotic component in the examined mean wind. Telegraph approximation is also used to study relative contribution of the chaotic and stochastic components to the mean wind fluctuations and an equilibrium between these components has been studied in detail.
Discriminating MSSM families in (free-field) Gepner Orientifolds

description: A complete analysis of orientifold compactifications involving Gepner models that are free fields (k=1,2) is performed. A set of tadpole solutions is found that are variants of a single chiral spectrum. The vacua found have the property that different families have different U(1) charges so that one family cannot obtain masses in perturbation theory. Its masses must come from instantons, allowing for a hierarchy of masses. The phenomenological aspects of such vacua are analyzed.

Multicomponent and Variable Velocity Galactic Outflow in Cosmological Hydrodynamic Simulations

Publisher: name: arXiv
Year: 2010
Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: We develop a new ``Multicomponent and Variable Velocity'' (MVV) galactic outflow model for cosmological smoothed particle hydrodynamic (SPH) simulations. The MVV wind model reflects the fact that the wind material can arise from different phases in the interstellar medium (ISM), and the mass-loading factor in the MVV model is a function of galaxy stellar mass. We find that the simulation with the MVV outflow has the following characteristics: (i) the intergalactic medium (IGM) is hardly heated up, and the mean IGM temperature is almost the same as in the no-wind run; (ii) it has lower cosmic star formation rates (SFRs) compared to the no-wind run, but higher SFRs than the constant velocity wind run; (iii) it roughly agrees with the observed IGM metallicity, and roughly follows the observed evolution of Omega(Civ); (iv) the lower mass galaxies have larger mass-loading factors, and the low-mass end of galaxy stellar mass function is flatter than in the previous simulations. Therefore, the MVV outflow model mildly alleviates the problem of too steep galaxy stellar mass function seen in the previous SPH simulations. In summary, the new MVV outflow model shows reasonable agreement with observations, and gives better results than the constant velocity wind model.

Discontinuous nonequilibrium phase transitions in a nonlinearly pulse-coupled excitable lattice model

description: We study a modified version of the stochastic susceptible-infected-refractory-susceptible (SIRS) model by employing a nonlinear (exponential) reinforcement in the contagion rate and no diffusion. We run simulations for complete and random graphs as well as d-dimensional hypercubic lattices (for d=3,2,1). For weak nonlinearity, a continuous nonequilibrium phase transition between an absorbing and an active phase is obtained, such as in the usual stochastic SIRS model [Joo and Lebowitz, Phys. Rev. E 70, 036114 (2004)]. However, for strong nonlinearity, the nonequilibrium transition between the two phases can be discontinuous for d>=2, which is confirmed by well-characterized hysteresis cycles and bistability. Analytical mean-field results correctly predict the overall structure of the phase diagram. Furthermore, contrary to what was observed in a model of phase-coupled stochastic oscillators with a similar nonlinearity in the coupling [Wood et al., Phys. Rev. Lett. 96, 145701 (2006)], we did not find a transition to a stable (partially) synchronized state in our nonlinearly pulse-coupled excitable elements. For long enough refractory times and high enough nonlinearity, however, the system can exhibit collective excitability and unstable stochastic oscillations.

Angular profile of emission of non-zero spin fields from a higher-dimensional black hole

description: Recent works have included the effect of rotation on simulations of black hole events at the LHC, showing that the angular momentum of the black hole cannot be ignored and it makes a non-trivial contribution for most of the lifetime of the black hole. A key consequence of the rotation of the black hole is that the Hawking radiation is no longer isotropic, making it more difficult to infer space-time parameters from measurements of the emitted particles. In this letter we study the angular distribution of the Hawking emission of non-zero spin particles with specific helicity on the brane. We argue that the shape of the distribution could be used as a measure of the angular momentum of the black hole.

description: We report on a new computer study into the existence of d^2 equiangular lines in d complex dimensions. Such maximal complex projective codes are conjectured to exist in all finite dimensions and are the underlying mathematical objects defining symmetric informationally complete measurements in quantum theory. We provide numerical solutions in all dimensions d <= 67 and, moreover, a putatively complete list of Weyl-Heisenberg covariant solutions for d <= 50. A symmetry analysis of this list leads to new algebraic solutions in dimensions d = 24, 35 and 48, which are given together with algebraic solutions for d = 4,..., 15 and 19.

Studies of pure rotational spectra of isolated molecules and molecular adducts using pulsed jet Fourier transform microwave (PJ-FTM) spectroscopy
Creators: name: Feng, Gang <1984>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2013
Subjects: CHIM/02 Chimica fisica

description: This thesis focuses on studying molecular structure and internal dynamics by using pulsed jet Fourier transform microwave (PJ-FTMW) spectroscopy combined with theoretical calculations. Several kinds of interesting chemical problems are investigated by analyzing the MW spectra of the corresponding molecular systems.
First, the general aspects of rotational spectroscopy are summarized, and then the basic theory on molecular rotation and experimental method are described briefly. ab initio and density function theory (DFT) calculations that used in this thesis to assist the assignment of rotational spectrum are also included.
From chapter 3 to chapter 8, several molecular systems concerning different kind of general chemical problems are presented. In chapter 3, the conformation and internal motions of dimethyl sulfate are reported. The internal rotations of the two methyl groups split each rotational transition into several components line, allowing for the determination of accurate values of the V3 barrier height to internal rotation and of the orientation of the methyl groups with respect to the principal axis system.
In chapter 4 and 5, the results concerning two kinds of carboxylic acid bi-molecules, formed via two strong hydrogen bonds, are presented. This kind of adduct is interesting also because a double proton transfer can easily take place, connecting either two equivalent or two non-equivalent molecular conformations. 
Chapter 6 concerns a medium strong hydrogen bonded molecular complex of alcohol with ether. The dimer of ethanol-dimethylether was chosen as the model system for this purpose.
Chapter 7 focuses on weak halogen…H hydrogen bond interaction. The nature of O-H…F and C-H…Cl interaction has been discussed through analyzing the rotational spectra of CH3CHClF/H2O. In chapter 8, two molecular complexes concerning the halogen bond interaction are presented.
Health care of health : the development of the elements of a plan to address the health needs of the elderly in British Columbia
Creators: name: McPhee, Margaret E.
Publisher: name: University of British Columbia
Year: 2010

description: This is an attempt at the development of the elements of a plan to address the health needs of the elderly in British Columbia, which could be directed to the minister of health of the Province. It begins with a review of provisions and legislation affecting this age group at the federal and Provincial level, and concludes that as services other than medical ones contribute to health, there is an undue emphasis on acute medical and institutional care, and a comparative inadequacy of those preventive and supportive community and social services which might meet many needs more appropriately and more economically. Most of the problems seem to stem from lack of any coherent policy with regard to the elderly - perhaps because it is only recently that they have been identified as a category, and partly because society's attitude to them is so ambivalent. It is suggested that the elderly do not require separate services but they do require a special policy. Most of the inappropriate aspects of the present delivery of health services affect all age groups and the elderly will only be able to benefit from recommended changes if they are made to the system as a whole. However, because of the increasing numbers of elderly in the population and their disproportionate consumption of medical services, and because of the evidence that many of their needs are being met inappropriately and uneconomically, it seems particularly desirable to make alternative services available to this age group. And because of their disadvantaged position with regard to income, family, friends and other social contacts, and energy compared with other age groups, it is recommended that a policy of positive discrimination be adopted towards this age group in the provision of preventive, community and social services. Various recommendations are made for elements which should be considered for inclusion in a plan, the main one being that it must be made in very close co-operation with the Department of Human Resources and with input to and/or from other relevant departments.
