description: A síndrome metabólica (SM) é uma doença cardiometabólica que está associada ao desenvolvimento de eventos cardiovasculares, cujo diagnóstico é realizado a partir da presença de pelo menos três fatores de risco, dentre eles podemos citar a obesidade visceral, hipertensão arterial, dislipidemia ou sedentarismo. Vários estudos afirmam a importância do exercício físico como coadjuvante na prevenção e tratamento de várias doenças crônico degenerativas, mas poucos relacionam seu impacto e eficiência no tratamento da SM. Mediante o exposto, este estudo teve como objetivo investigar, através de uma revisão da literatura, o impacto do exercício aeróbio e resistido no tratamento da síndrome metabólica, visando contribuir e propiciar aos profissionais da área da saúde uma importante discussão acerca dessa patologia, sugerindo como opção de profilaxia e tratamento a utilização do exercício físico. Para tanto, realizou-se uma busca, restrita aos últimos 10 anos (1999-2009), nas bases de dados Scielo, Google Acadêmico, Bireme, Pubmed e periódicos especializados. Foram selecionados 70 artigos pertinentes ao tema. Os termos utilizados para pesquisa foram: síndrome metabólica, exercício aeróbio, exercício resistido. A partir dos resultados levantados na literatura pesquisada, pôde-se concluir que, são inquestionáveis os benefícios e ação dos exercícios físicos aeróbios e resistidos na prevenção e tratamento da síndrome metabólica, uma vez que, estas modalidades de exercícios, aparentemente, têm grande impacto sobre os fatores que determinam a doença. Assim, vemos ser de grande relevância se considerar a implantação de programas de exercícios físicos orientados em ações de saúde pública no Brasil.

description: We study the smoothness of the density of a semilinear heat equation with multiplicative spacetime white noise. Using Malliavin calculus, we reduce the problem to a question of negative moments of solutions of a linear heat equation with multiplicative white noise. Then we settle this question by proving that solutions to the linear equation have negative moments of all orders.

Description: Sponge body tubular and repent with some anastomosis (Fig. 4A, B). The anastomosis is variable; it can be loose and sparse or dense, with tubes closely attached to each other. Tubes are mostly cylindrical, but commonly compressed in few parts, giving the body a folded appearance. Consistency harsh to the touch, relatively firm and friable. Colour white or pink in life and white, beige to light brown or pink after fixation (Fig. 4A, B). Outer surface smooth. Body wall thin (Fig. 4C). Atrial cavity wide and spacious. Atrial surface slightly hispid due to the apical actines of cortical and atrial tetractines. Oscula are few, simple circular apertures without ornamentation (Fig. 5A). The aquiferous system represents the new type, kladonoid, with choanocyte chambers mostly elongated and ramified, commonly these ramifications fuse with each other (Fig. 4C).
Skeleton: The oscular margin has a transitional skeleton comprised of large sagittal triactines and tetractines, gradually becoming regular as the body wall thickens. Cortical skeleton well developed, with several layers of tangential triactines and tetractines (Fig. 4D). Choanosomal skeleton reduced, with many regular triactines and tetractines sparse around the canals (Fig. 4E). Excurrent canals and atrial skeleton comprised of sagittal triactines and tetractines, lying tangentially, with the apical actines pointing into the atrial cavity (Fig. 4F).

description: Using an N=4, d=1 superfield approach, we construct an N=8 supersymmetric action of the self-interacting off-shell N=8 multiplet {\bf (1, 8, 7)}. This action is found to be invariant under the exceptional N=8, d=1 superconformal group F(4) with the R-symmetry subgroup SO(7). The general N=8 supersymmetric {\bf (1, 8, 7)} action is a sum of the superconformal action and the previously known free bilinear action. We show that the general action is also superconformal, but with respect to redefined superfield transformation laws. The scalar potential can be generated by two Fayet-Iliopoulos N=4 superfield terms which preserve N=8 supersymmetry but break the superconformal and SO(7) symmetries.

description: Spatially-smoothed sources are often utilized in the pseudospectral time-domain (PSTD) method to suppress the associated aliasing errors to levels as low as possible. In this work, the explicit conditions of the optimal source patterns for these spanning sources are presented based on the fact that the aliasing errors are mainly attributed to the high spatial-frequency parts of the time-stepped source items and subsequently demonstrated to be exactly corresponding to the normalized rows of Pascal's triangle. The outstanding performance of these optimal sources is verified by the practical 1-D, 2-D and 3-D PSTD simulations and compared with that of non-optimal sources.

description: We investigate the ground state properties of a disordered superfluid Fermi gas across the BCS-BEC (Bose Einstein condensate) crossover. We show that, for weak disorder, both the depletion of the condensate fraction of pairs and the normal fluid density exhibit a nonmonotonic behavior as a function of the interaction parameter $1/k_Fa$, reaching their minimum value near unitarity. We find that, moving away from the weak coupling BCS regime, Anderson's theorem ceases to apply and the superfluid order parameter is more and more affected by the random potential.

description: A quantum theory representations of real (R) and complex (C) numbers is given that is based on states of single, finite strings of qukits for any base k > 1. Both unary representations and the possibility that qukits with k a prime number are elementary and the rest composite are discussed. Cauchy sequences of qukit string states are defined from the arithmetic properties. The representations of R and C, as equivalence classes of these sequences, differ from classical kit string state representations in two ways: the freedom of choice of basis states, and the fact that each quantum theory representation is part of a mathematical structure that is itself based on the real and complex numbers. These aspects enable the description of 3 dimensional frame fields labeled by different k values, different basis or gauge choices, and different iteration stages. The reference frames in the field are based on each R and C representation where each frame contains representations of all physical theories as mathematical structures based on the R and C representation. Approaches to integrating this with physics are described. It is observed that R and C values of physical quantities, matrix elements, etc. which are viewed in a frame as elementary and featureless, are seen in a parent frame as equivalence classes of Cauchy sequences of qukit string states.

description: It is well-known that the perturbations of Schwarzschild black holes are governed by a wave equation with some effective potential. We consider perturbations of a gas in a tube called Laval nozzle, which is narrow in the middle and has a sonic point in the throat. By equating the wave equation in a Laval nozzle of an arbitrary form with the wave equation of spin-s perturbations of Schwarzschild black holes, we find the exact expression for the form of the Laval nozzle, for which acoustic perturbations of the gas flow corresponds to the general form of perturbations of Schwarzschild black holes. This allows observation, in a laboratory, of the acoustic waves, which are analogue of damping quasinormal oscillations of Schwarzschild black holes. The found exact acoustic analog allows to observe also some other phenomena governed by the wave equation, such as the wave scattering and tunneling.

description: The antiferromagnetic ground state of copper oxide Mott insulators is achieved by localizing an electron at each copper atom in real space (r-space). Removing a small fraction of these electrons (hole doping) transforms this system into a superconducting fluid of delocalized Cooper pairs in momentum space (k-space). During this transformation, two distinctive classes of electronic excitations appear. At high energies, the enigmatic 'pseudogap' excitations are found, whereas, at lower energies, Bogoliubov quasi-particles -- the excitations resulting from the breaking of Cooper pairs -- should exist. To explore this transformation, and to identify the two excitation types, we have imaged the electronic structure of Bi2Sr2CaCu2O8+d in r-space and k-space simultaneously. We find that although the low energy excitations are indeed Bogoliubov quasi-particles, they occupy only a restricted region of k-space that shrinks rapidly with diminishing hole density. Concomitantly, spectral weight is transferred to higher energy r-space states that lack the characteristics of excitations from delocalized Cooper pairs. Instead, these states break translational and rotational symmetries locally at the atomic scale in an energy independent fashion. We demonstrate that these unusual r-space excitations are, in fact, the pseudogap states. Thus, as the Mott insulating state is approached by decreasing the hole density, the delocalized Cooper pairs vanish from k-space, to be replaced by locally translational- and rotational-symmetry-breaking pseudogap states in r-space.

description: We study the relationship between the H{\sc i} specific angular momentum (j$_{\rm g}$) and the H{\sc i} mass (M$_{\rm g}$) for a sample of galaxies with well measured H{\sc i} rotation curves. We find that the relation is well described by an unbroken power law \jg $\propto$ \mg$^α$ over the entire mass range (10$^{7}$-10$^{10.5}$ M$_{\odot}$), with $α= 0.89 \pm 0.05$ (scatter 0.18 dex). This is in reasonable agreement with models which assume that evolutionary processes maintain H{\sc i} disks in a marginally stable state. The slope we observe is also significantly different from both the $j \propto M^{2/3}$ relation expected for dark matter haloes from tidal torquing models and the observed slope of the specific angular momentum-mass relation for the stellar component of disk galaxies. Our sample includes two H{\sc i}-bearing ultra diffuse galaxies, and we find that their angular momentum follows the same relation as other galaxies. The only discrepant galaxies in our sample are early-type galaxies with large rotating H{\sc i} disks which are found to have significantly higher angular momentum than expected from the power law relation. The H{\sc i} disks of all these early-type galaxies are misaligned or counter-rotating with respect to the stellar disks, consistent with the gas being recently accreted. We speculate that late stage wet mergers, as well as cold flows play a dominant role in determining the kinematics of the baryonic component of galaxies as suggested by recent numerical simulations.

Position effect variegation in Drosophila melanogaster : chemical modification and mutational analysis
Creators: name: Mottus, Randall C.
Publisher: name: University of British Columbia
Year: 2010

description: Position effect variegation is an event in which the transcriptional fate of a gene is determined long before the product of that gene is required. Thus, it parallels the normal processes of determination and differentiation associated with development in higher organisms. Position effect variegation is thought to result from alterations in chromatin structure at the new heterochromatic-euchromatic boundary. I have found that when fruit flies (Drosophila melanoqaster), bearing a variegating gene, are reared on meduim containing low concentrations of either n-butyrate or n-propionate, the gene inactivation associated with position effect variegation is suppressed. This is true of both X-linked and autosomal variegating genes regardless of the type of heterochromatin with which they are associated. These chemicals are only effective as suppressors of variegation during the embryonic and larval stages suggesting they may only act to modify variegation in dividing cells. Removal of the Y chromosome in males completely abolishes the effects of n-butyrate and n-propionate. I examined the ability of these chemicals to. suppress variegation in flies haploid for the histone gene cluster and found that the combined effect was additive. These results are discussed with respect to current knowledge of chromatin structure and the known effects of n-butyrate and n-propionate. In addition a large scale screen was undertaken to isolate and recover dominant mutations which either suppress or enhance the variegated phenotype. In total, 54 mutations were recovered: 51 suppressors, and 3 enhancers. Preliminary characterization has revealed that the majority of the suppressor mutations are clustered at specific sites in the D. Melanogaster genome. A majority of the suppressors are sensitive to the heterochromatic constitution of the organism but most are insensitive to alterations in developmental temperature. The possibility that' some of these mutations represent lesions in genes coding for structural components of chromatin suggests further characterization, both at the genetic and molecular level, may provide insights not only into position effect variegation but also provide information regarding the basic structure of chromatin.

description: In 1960 Edward Lorenz (1917-2008) published a pioneering work on the `maximum simplification' of the barotropic vorticity equation. He derived a coupled three-mode system and interpreted it as the minimum core of large-scale fluid mechanics on a `finite but unbounded' domain. The model was obtained in a heuristic way, without giving a rigorous justification for the chosen selection of modes. In this paper, it is shown that one can legitimate Lorenz' choice by using symmetry transformations of the spectral form of the vorticity equation. The Lorenz three-mode model arises as the final step in a hierarchy of models constructed via the component reduction by means of symmetries. In this sense, the Lorenz model is indeed the `maximum simplification' of the vorticity equation.

description: Extrasolar planets observation and characterization by high contrast imaging instruments is set to be a very important subject in observational astronomy. Dedicated instruments are being developed to achieve this goal with very high efficiency. In particular, full spectroscopic characterization of low temperature planetary companions is an extremely important milestone. We present a new data analysis method for long slit spectroscopy (LSS) with coronagraphy, which allows characterization of planetary companions of low effective temperature. In a speckle-limited regime, this method allows an accurate estimation and subtraction of the scattered starlight, to extract a clean spectrum of the planetary companion. We performed intensive LSS simulations with IDL/CAOS to obtain realistic spectra of low (R=35) and medium (R=400) resolution in the J, H, and K bands. The simulated spectra were used to test our method and estimate its performance in terms of contrast reduction and extracted spectra quality. Our simulations are based on a software package dedicated to the development of SPHERE, a second generation instrument for the ESO-VLT. Our method allows a contrast reduction of 0.5 to 2.0 magnitudes compared to the coronagraphic observations. For M0 and G0 stars located at 10 pc, we show that it would lead to the characterization of companions with Teff of 600 K and 900 K respectively, at angular separations of 1.0 as. We also show that errors in the wavelength calibration can produce significant errors in the characterization, and must therefore be minimized as much as possible.

description: The one-step replica symmetry breaking (RSB) is used to study a two-sublattice fermionic infinite-range Ising spin glass (SG) model in a transverse field $Γ$. The problem is formulated in a Grassmann path integral formalism within the static approximation. In this model, a parallel magnetic field $H$ breaks the symmetry of the sublattices. It destroys the antiferromagnetic (AF) order, but it can favor the nonergodic mixed phase (SG+AF) characterizing an asymmetric RSB region. In this region, intra-sublattice disordered interactions $V$ increase the difference between the RSB solutions of each sublattice. The freezing temperature shows a higher increase with $H$ when $V$ enhances. A discontinue phase transition from the replica symmetry (RS) solution to the RSB solution can appear with the presence of an intra-sublattice ferromagnetic average coupling. The $Γ$ field introduces a quantum spin flip mechanism that suppresses the magnetic orders leading them to quantum critical points. Results suggest that the quantum effects are not able to restore the RS solution. However, in the asymmetric RSB region, $Γ$ can produce a stable RS solution at any finite temperature for a particular sublattice while the other sublattice still presents RSB solution for the special case in which only the intra-sublattice spins couple with disordered interactions.

description: We study the cosmological implications of including angular motion in the DBI brane inflation scenario. The non-canonical kinetic terms of the Dirac-Born-Infeld action give an interesting alternative to slow roll inflation, and cycling branes can drive periods of accelerated expansion in the Universe. We present explicit numerical solutions demonstrating brane inflation in the Klebanov-Strassler throat. We find that demanding sufficient inflation takes place in the throat is in conflict with keeping the brane's total energy low enough so that local gravitational backreaction on the Calabi-Yau manifold can be safely ignored. We deduce that spinflation (brane inflation with angular momentum) can ease this tension by providing extra e-foldings at the start of inflation. Cosmological expansion rapidly damps the angular momentum causing an exit to a more conventional brane inflation scenario. Finally, we set up a general framework for cosmological perturbation theory in this scenario, where we have multi-field non-standard kinetic term inflation.

description: We derive a general formula of the reduced fidelity susceptibility when the reduced density matrix is $2\times2$ block-diagonal. By using this result and the continuous unitary transformations, we study finite-size scaling of the reduced fidelity susceptibility in the Lipkin-Meshkov-Glick Model. It is found that it can be used to characterize quantum phase transitions, implying that we can extract information of quantum phase transitions only from the fidelity of a subsystem, which is of practical meaning in experiments.

description: We study Fermi edge singularities in photo-absorption spectra of generic mesoscopic systems such as quantum dots or nanoparticles. We predict deviations from macroscopic-metallic behavior and propose experimental setups for the observation of these effects. The theory is based on the model of a localized, or rank one, perturbation caused by the (core) hole left behind after the photo-excitation of an electron into the conduction band. The photo-absorption spectra result from the competition between two many-body responses, Anderson's orthogonality catastrophe and the Mahan-Nozieres-DeDominicis contribution. Both mechanisms depend on the system size through the number of particles and, more importantly, fluctuations produced by the coherence characteristic of mesoscopic samples. The latter lead to a modification of the dipole matrix element and trigger one of our key results: a rounded K-edge typically found in metals will turn into a (slightly) peaked edge on average in the mesoscopic regime. We consider in detail the effect of the "bound state" produced by the core hole.

description: We present new proper motions from the 10 m Keck telescopes for a puzzling population of massive, young stars located within 3.5" (0.14 pc) of the supermassive black hole at the Galactic Center. Our proper motion measurements have uncertainties of only 0.07 mas/yr (3 km/s), which is ~7 times better than previous proper motion measurements for these stars, and enables us to measure accelerations as low as 0.2 mas/yr^2 (7 km/s/yr). Using these measurements, line-of-sight velocities from the literature, and 3D velocities for additional young stars in the central parsec, we constrain the true orbit of each individual star and directly test the hypothesis that the massive stars reside in two stellar disks as has been previously proposed. Analysis of the stellar orbits reveals only one of the previously proposed disks of young stars using a method that is capable of detecting disks containing at least 7 stars. The detected disk contains 50% of the young stars, is inclined by ~115 deg from the plane of the sky, and is oriented at a position angle of ~100 deg East of North. Additionally, the on-disk and off-disk populations have similar K-band luminosity functions and radial distributions that decrease at larger projected radii as \propto r^-2. The disk has an out-of-the-disk velocity dispersion of 28 +/- 6 km/s, which corresponds to a half-opening angle of 7 +/- 2 deg, and several candidate disk members have eccentricities greater than 0.2. Our findings suggest that the young stars may have formed in situ but in a more complex geometry than a simple, thin circular disk.

description: We consider continuous $SL(2,\mathbb{R})$-cocycles over a strictly ergodic homeomorphism which fibers over an almost periodic dynamical system (generalized skew-shifts). We prove that any cocycle which is not uniformly hyperbolic can be approximated by one which is conjugate to an $SO(2,\mathbb{R})$-cocycle. Using this, we show that if a cocycle's homotopy class does not display a certain obstruction to uniform hyperbolicity, then it can be $C^0$-perturbed to become uniformly hyperbolic. For cocycles arising from Schrödinger operators, the obstruction vanishes and we conclude that uniform hyperbolicity is dense, which implies that for a generic continuous potential, the spectrum of the corresponding Schrödinger operator is a Cantor set.

description: We investigate the axial-vector transition constants of the baryon antidecuplet to the octet and decuplet within the framework of the self-consistent SU(3) chiral quark-soliton model. Taking into account rotational 1/N_c and linear m_s corrections and using the symmetry-conserving quantization, we calculate the axial-vector transition constants. It is found that the leading-order contributions are generally almost canceled by the rotational 1/N_c corrections. Thus, the m_s corrections turn out to be essential contributions to the axial-vector constants. The decay width of the Theta^+ to NK transition is determined to be Gamma(Theta -> NK)=0.71, MeV, based on the result of the axial-vector transition constant g_A^* (Theta -> NK)=0.05. In addition, other strong decays of the baryon antidecuplet are investigated.

description: We present a study of spinning black hole binaries focusing on the spin dynamics of the individual black holes as well as on the gravitational recoil acquired by the black hole produced by the merger. We consider two series of initial spin orientations away from the binary orbital plane. In one of the series, the spins are anti-aligned; for the second series, one of the spins points away from the binary along the line separating the black holes. We find a remarkable agreement between the spin dynamics predicted at 2nd post-Newtonian order and those from numerical relativity. For each configuration, we compute the kick of the final black hole. We use the kick estimates from the series with anti-aligned spins to fit the parameters in the \KKF{,} and verify that the recoil along the direction of the orbital angular momentum is $\propto \sinθ$ and on the orbital plane $\propto \cosθ$, with $θ$ the angle between the spin directions and the orbital angular momentum. We also find that the black hole spins can be well estimated by evaluating the isolated horizon spin on spheres of constant coordinate radius.

Type specimen: Holotype (BMNH 1884.4.22.60).
Type locality: Off Kerguelen Island, South Indian Ocean (49°30ʹ S, 70°30ʹ E). Kerguelen Islands MEOW ecoregion.
Description: The holotype is only a small fragment (Fig. 28A, B). Colour light beige (surface) and brown (mesohyl) in ethanol. Compressible and soft to the touch. Outer surface smooth. Atrial surface hispid due to the apical actines of tetractines. Osculum could not be seen. Body wall thick. Atrial cavity spacious with conspicuous excurrent canals. Aquiferous system peculiar: near the cortex (one-third of the body wall) the choanocyte chambers are elongated and cylindrical (syconoid), while near the atrial surface (other twothirds) they are subspherical (leuconoid) (Fig. 28C). Large granular cells found surrounding the canals. Few young oocytes present in the holotype.
Skeleton: Oscular margin with sagittal triactines that gradually become regular as the body wall thickens. Cortical skeleton well developed, although not as thick as the choanosome. It is comprised of several layers of tangential triactines and tetractines (Fig. 28C). The apical actine of the cortical tetractines crosses the choanosome, sometimes penetrating the atrium. The choanosomal skeleton is comprised of pygmy triactines and tetractines, mostly present around canals. These spicules are also present in the atrium, laying tangentially, with pygmy tetractines being more abundant and projecting their apical actine into the atrial cavity.

Exploring a British Columbia cultural centre : a focus for the secondary art curriculum
Creators: name: Carmichael, Lynne Alison
Publisher: name: University of British Columbia
Year: 2010

description: This study describes and explains an approach to the implementation of the Art Foundations component of the Secondary Art curriculum. The project covered an intensive five month period of preparation and a five week period of implementation. Particular emphasis has been placed on the use of local cultural centres as practical sources for materials in satisfying the Art Foundations learning outcomes. The program attempts to identify and suggest possible solutions to problems experienced by both local cultural centres and school art educators. In particular, it suggests possible types of materials needed by art educators to make the most effective use of their local arts centre. A teacher manual "More Than Meets the Eye" was devised to assist the teachers in the preparation of their classes for their visit to the local cultural centre. Individual student kits were also developed containing materials to focus pupil viewing at specific exhibits in the Richmond Arts Centre. The proposed learning outcomes suggested in the Secondary Art curriculum have served as signposts in the development of these materials. The value and potential for using this approach to implementation of the Art Foundations component of the Secondary Art curriculum was then explored with special emphasis on the statistical data, and personal interviews conducted by the researcher. Results of the data collection indicated that this approach has potential to facilitate integrating the Art Foundations component with exhibits at the Richmond Arts Centre. The majority of the teachers and students as well as the various Co-ordinators expressed highly positive reactions to the project. Future consideration of this approach to the Art Foundations component of the Secondary Art curriculum is recommended.
Does the accreting millisecond pulsar XTE J1814-338 precess?

description: Precession in an accretion-powered pulsar is expected to produce characteristic variations in the pulse properties. Assuming surface intensity maps with one and two hotspots, we compute theoretically the periodic modulation of the mean flux, pulse-phase residuals and fractional amplitudes of the first and second harmonic of the pulse profiles. These quantities are characterised in terms of their relative precession phase offsets. We then search for these signatures in 37 days of X-ray timing data from the accreting millisecond pulsar XTE J1814-338. We analyse a 12.2-d modulation observed previously and show that it is consistent with a freely precessing neutron star only if the inclination angle is < 0.1 degrees, an a priori unlikely orientation. We conclude that if the observed flux variations are due to precession, our model incompletely describes the relative precession phase offsets (e.g. the surface intensity map is over-simplified). We are still able to place an upper limit on εof 3.0 x 10^{-9} independently of our model, and estimate the phase-independent tilt angle θ; to lie roughly between 5 and 10 degrees. On the other hand, if the observed flux variations are not due to precession, the detected signal serves as a firm upper limit for any underlying precession signal. We then place an upper limit on the product εcos(θ) of \leq 9.9 x 10^{-10}. The first scenario translates into a maximum gravitational wave strain of 10^{-27} from XTE J1814-338 (assuming a distance of 8 kpc), and a corresponding signal-to-noise ratio of \leq 10^{-3} (for a 120 day integration time) for the advanced LIGO ground-based gravitational wave detector.

description: The gluon-gluon induced terms for Higgs production through weak-boson fusion are calculated. They form a finite and gauge-invariant subset of the NNLO corrections in the strong coupling constant. This is also the lowest order with sizeable t-channel colour exchange contributions, leading to additional hadronic activity between the outgoing jets.

description: We report on a dramatic improvement of the performance of the classical time-delayed autosynchronization method (TDAS) to control unstable steady states, by applying a time-varying delay in the TDAS control scheme in a form of a deterministic or stochastic delay-modulation in a fixed interval around a nominal value $T_0$. The successfulness of this variable delay feedback control (VDFC) is illustrated by a numerical control simulation of the Lorenz and Rössler systems using three different types of time-delay modulations: a sawtooth wave, a sine wave, and a uniform random distribution. We perform a comparative analysis between the VDFC method and the standard TDAS method for a sawtooth-wave modulation by analytically determining the domains of control for the generic case of an unstable fixed point of focus type.
