Weak lensing ellipticities in a strong lensing regime

Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: It is now routine to measure the weak gravitational lensing shear signal from the mean ellipticity of distant galaxies. However, conversion between ellipticity and shear assumes local linearity of the lensing potential (ie that the spatial derivatives of the shear are small), and this condition is not satisfied in some of the most interesting regions of the sky. We extend a derivation of lensing equations to include higher order terms, and assess the level of biases introduced by assuming that first-order weak lensing theory holds in a relatively strong shear regime. We find that, even in a worst-case scenario, a fully linear analysis is accurate to within 1% outside ~1.07 times the Einstein radius of a lens, by deriving an analytic function that can be used to estimate the applicability of any first-order analysis. The effect is too small to explain the discrepancy between weak- and strong-lensing estimates of the mass of the bullet cluster, and should not impact cluster surveys for the forseeable future. In fact, it means that arclets can be used to measure shears closer to a cluster core than has been generally appreciated. However, at the level of accuracy demanded by future lensing surveys, this bias ought to be considered in measurements of the inner slope of cluster mass distributions and the small-scale end of the mass power spectrum. Both of these are central in determining the relationship between baryonic and dark matter.

description: We have investigated the detailed torque-reversal behavior of 4U 1626--67 in the framework of the recently developed comprehensive model of the inner disk radius and torque calculations for neutron stars accreting from geometrically thin disks. The model can reproduce the torque -- X-ray luminosity relation across the torque reversals of 4U 1626--67. Our results imply that: (1) rotational equilibrium is reached when the inner disk radius equals the co-rotation radius, $r_\mathrm{co}$, while the conventional Alfven radius is greater than and close to $r_\mathrm{co}$, (2) both spin-up and spin-down torques are operating on either side of torque reversal, (3) with increasing accretion rate the spin-up torque associated with accretion onto the star gradually dominates the spin-down torque exerted by the disk. The torque reversals are the natural outcome of transitions between the well-defined weak-propeller and spin-up phases of the star with a stable geometrically thin accretion disk.

description: The Women's Health Initiative randomized clinical trial of hormone therapy found no benefit of hormones in preventive cardiovascular disease, a finding in striking contrast with a large body of observational research. Understanding whether better methodology and/or statistical adjustment might have prevented the erroneous conclusions of observational research is important. This is a re-analysis of data from a case-control study examining the relationship of postmenopausal hormone therapy and the risks of myocardial infarction (MI) and ischemic stroke in which we reported no overall increase or decrease in the risk of either event. Variables measuring health behavior/lifestyle that are not likely to be causally with the risks of MI and stroke (e.g., sunscreen use) were included in multivariate analysis along with traditional confounders (age, hypertension, diabetes, smoking, body mass index, ethnicity, education, prior coronary heart disease for MI and prior stroke/TIA for stroke) to determine whether adjustment for the health behavior/lifestyle variables could reproduce or bring the results closer to the findings in a large and definitive randomized clinical trial of hormone therapy, the Women's Health Initiative. For both MI and stroke, measures of health behavior/lifestyle were associated with odds ratios (ORs) less than 1.0. Adjustment for traditional cardiovascular disease confounders did not alter the magnitude of the ORs for MI or stroke. Addition of a subset of these variables selected using stepwise regression to the final MI or stroke models along with the traditional cardiovascular disease confounders moved the ORs for estrogen and estrogen/progestin use closer to values observed in the Women Health Initiative clinical trial, but did not reliably reproduce the clinical trial results for these two endpoints.

Community ideology and the ideology of community : the Orokaiva case
Creators: name: Braun, Nickolai G.
Publisher: name: University of British Columbia
Year: 2010

description: "Community" is a word that suffuses Western discourse. Its use is widespread in both popular and in the more specialized languages of anthropology and sociology. Though rich in meaning, "community" is yet often employed to arbitrarily bind people together 'from the outside'. Thus 'a community', 'peasant communities', and so on, refer to bounded entities that are there. This thesis begins by taking community as a problem. For though we write easily .about, and easily apply, the concept of 'a community', the notion of being 'in community', taking community to refer, to a shared or common quality or state of being, is not so easily applied, let alone thought. What ivS therefore explored is a notion of community as a process, both generally and in relation to a particular Papua New Guinean people, the Orokaiva. As a process, community is taken to be 'emergent', rather than 'there'. "Community" is subsequently developed as an alternative paradigm of order to the descent-based models of Williams, Crocombe & Hogbin, Rimoldi and Schwimmer. The Orokaiva plant emblem, a central symbol of Orokaiva sociality, is focused on. Stemming from a notion of 'emergent community', the interrelated .problems of identification, affiliation, ideology, and context are selected and pursued in relation to the Orokaiva plant emblem. I follow McKellin's (1980) delineation of three ordering principles -- lineality, territoriality, and exchange/commen-sality -- from Managalase kinship ideology; these same three principles are shown to underlie some Orokaiva notions of plant emblem identification. Taking these ordering principles together with some Orokaiva notions of "substance", a complex of interrelated Orokaiva ideas is delineated. It is this ideational order which is hypothesized as constituting the ideational resources engaged in the indigenous rationalization of Orokaiva sociality. Some contexts generated by three events -- birth, marriage, and death -- are analysed in the light of that complex of ideas termed an 'ideology of community'. Referred to as 'contexts for community' , they suggest some of the possible ways in-which the ideational order is utilized to close the ambiguities of sociality and make the phenomenological dimension of "community" visible. Reliant upon the ethnographic work of others, this thesis is primarily forwarded as a problem-seeking, rather than a problem-solving study. Will "community" ever be found among the Orokaiva?

description: The aim of this work was to map and discuss the technical and tactical contents (offensive and defensive) of the handball under-12 teams, with speeches from expert coaches. The sample consisted of six coaches, whose interviews were tabulated and analyzed based on Collective Subject Discourse method. The results of defensive contents showed that is important the development of the individual system, the different technical and tactical elements and to teach some zonal systems. On the offensive content emphasizes argue the need of different tactical-strategic options facing the individual and zonal defensive systems, and also noted that some coaches value the efficient execution of technical movements and others that are more concerned with players game comprehension and the multiple experiences of them. Is evident, based on discussion of the results and the literature consulted, the concern with the development of the gaming skills (such as perception, attention, anticipation and decision making) from diversified experiences, allowing players to experience different playing positions without targeting early specialization.

description: The tidal perturbation of embedded protoplanets on their natal disks has been widely attributed to be the cause of gap-ring structures in sub-mm images of protoplanetary disks around T Tauri stars. Numerical simulations of this process have been used to propose scalings of characteristic dust gap width/gap-ring distance with respect to planet mass. Applying such scalings to analyze observed gap samples yields a continuous mass distribution for a rich population of hypothetical planets in the range of several Earth to Jupiter masses. In contrast, the conventional core-accretion scenario of planet formation predicts a bi-modal mass function due to 1) the onset of runaway gas accretion above \sim20 Earth masses and 2) suppression of accretion induced by gap opening. Here we examine the dust disk response to the tidal perturbation of eccentric planets as a possible resolution of this paradox. Based on simulated gas and dust distributions, we show the gap-ring separation of Neptune-mass planets with small eccentricities might become comparable to that induced by Saturn-mass planets on circular orbits. This degeneracy may obliterate the discrepancy between the theoretical bi-modal mass distribution and the observed continuous gap width distribution. Despite damping due to planet-disk interaction, modest eccentricity may be sustained either in the outer regions of relatively thick disks or through resonant excitation among multiple super Earths. Moreover, the ring-like dust distribution induced by planets with small eccentricities is axisymmetric even in low viscosity environments, consistent with the paucity of vortices in ALMA images.

description: Gravitational radiation of binary systems can be studied by using the adiabatic approximation in General Relativity. In this approach a small astrophysical object follows a trajectory consisting of a chained series of bounded geodesics (orbits) in the outer region of a Kerr Black Hole, representing the space time created by a bigger object. In our paper we study the entire class of orbits, both of constant radius (spherical orbits), as well as non-null eccentricity orbits, showing a number of properties on the physical parameters and trajectories. The main result is the determination of the geometrical locus of all the orbits in the space of physical parameters in Kerr space-time. This becomes a powerful tool to know if different orbits can be connected by a continuous change of their physical parameters. A discussion on the influence of different values of the angular momentum of the hole is given. Main results have been obtained by analytical methods.

description: The overall aim of this article was to present a positive case study about how a sport club can foster both elite athlete development in parallel with offering a diverse range of sport activities to attract and maintain a greater number of children and youth for continued participation in a long term sport program.  To this end, an in-depth case study was conducted of a model Spanish Basketball Club, considered an example of success in achieving consistent level of performance and high rates of participation among their youth. Data were collected from in-depth interviews with administrators, setting observation, and analysis of current and archived club documents. The results show that the club has created changes over the years that have led to a clear organizational structure with a philosophy that connects its youth development teams and elite teams. An increase focus on youth development, the addition of recreational activities, and the implementation of a coach education program have been linked to enhanced participation rate and performance.

description: The present study aimed to study acute hematologic responses in individuals undergoing a  cardiopulmonary maximum incremental treadmill test without inclination. Were analyzed 23 individuals, 12 men and 11 women, with a mean age of 30.2 (± 8.4) years, mean weight of 68.1 (± 18.1) kg, mean height of 170.2 (± 9.8) cm, and mean BMI of 23.2 (±3.7) kg/m², physically active, with a minimum practice of 3.5 hours per week of exercise for at least 6 months. The subjects were submitted to a maximal incremental treadmill test, with venous blood collection for analysis before and immediately after completion of the test. Was used Wilcoxon test for analysis of pre and post test variables. Was adopted p < 0.05 as significance level. There was a significant increase in leukocyte count (69.23%; p = 0.005), lymphocytes (17.56%; p = 0.043), monocytes (85.41%; p = 0.012) and granulocytes (28.21%; p = 0.011). It was also observed a significant increase in erythrocytes (3,42%; p = 0,042), hematocrit (5.39%; p = 0.038) and hemoglobin (5.58%; p = 0.013). With this study, was concluded that performing a maximal test of treadmill running can significantly raise blood levels of leukocytes and respective sub-populations, as well as red blood cells and hemoglobin.

description: In this paper we study the geodesic structure of the Schwarzschild black hole in rainbow gravity analyzing the behavior of null and time-like geodesic. We find that the structure of the geodesics essentially does not change when the semi-classical effects are included. However, we can distinguish different scenarios if we take into account the effects of rainbow gravity. Depending on the type of rainbow functions under consideration, inertial and external observers see very different situations in radial and non radial motion of a test particles.

description: Neptune's moon Triton shares many similarities with Pluto, including volatile cycles of N2, CH4 and CO, and represents a benchmark case for the study of surface-atmosphere interactions on volatile-rich KBOs. Within the context of New Horizons observations of Pluto as well as recent Earth-based observations of Triton, we adapt a Plutonian VTM to Triton, and test its ability to simulate its volatile cycles, thereby aiding our understanding of its climate. We present VTM simulations exploring the volatile cycles on Triton over long-term and seasonal timescales for varying model parameters. We explore what scenarios and model parameters allow for a best match of the available observations. In particular, our set of observational constraints include Voyager 2 observations, ground-based NIR (0.8 to 2.4 μm) disk-integrated spectra and the evolution of surface pressure as retrieved from stellar occultations. Our results show that Triton's poles act as cold traps for volatile ices and favor the formation of polar caps extending to lower latitudes through glacial flow. As previously evidenced by other VTMs, North-South asymmetries in surface properties can favor the development of one cap over the other. Our best-case simulations are obtained for a global reservoir of N2 ice thicker than 200 m and a bedrock thermal inertia larger than 500 SI. The large N2 ice reservoir implies a permanent N2 southern cap extending to the equator. Our results also suggest that a small permanent polar cap exists in the northern (currently winter) hemisphere if the internal heat flux remains radiogenic (< 3 mW m-2). Finally, we provide predictions for the evolution of ice distribution, surface pressure, CO and CH4 atmospheric mixing ratios in the next decades. We also model the thermal lightcurves of Triton in 2022, which serve as predictions for future JWST observations.

description: We present Northern Extended Millimeter Array (NOEMA) CO(2-1) maps of the z=0.4418 cluster-central QSO IRAS 09104+4109, which trace ~4.5x10^10 Msol of molecular gas in and around the galaxy. As in many low redshift cool core clusters, the molecular gas is located in a series of clumps extending along the old radio jets and lobes. It has a relatively low velocity dispersion (336 [+39,-35] km/s FWHM) and shows no velocity gradients indicative of outflow or infall. Roughly half the gas is located in a central clump on the northeast side of the galaxy, overlapping a bright ionized gas filament and a spur of excess X-ray emission, suggesting that this is a location of rapid cooling. The molecular gas is unusually extended, out to ~55 kpc radius, comparable to the scale of the filamentary nebula in the Perseus cluster, despite the much higher redshift of this system. The extent falls within the thermal instability radius of the intracluster medium (ICM), with t_cool/t_ff<25 and t_cool}/t_eddy~1 within ~70 kpc. Continuum measurements at 159.9 GHz from NOEMA and 850 micron from the JCMT SCUBA-2 show excess far infrared emission, which we interpret as free-free emission arising from the ongoing starburst. These observations suggest that ICM cooling is not strongly affected by the buried QSO, and that cooling from the ICM can build gas reservoirs sufficient to fuel quasar-mode activity and drive the reorientation of the central AGN.

Although two electroweak bidoublets are introduced to accommodate the observed fermion masses and mixings, a natural missing partner mechanism insures that a single pair of MSSM Higgs doublets survives below the left-right symmetry breaking scale. If this scale happens to lie in the TeV range, several new particles potentially much lighter than the SU(2)_R charged gauge bosons W_R^+- will be accessible at the LHC.

description: The purpose of this study was to examine the effectiveness of a physical education (PE) program focused on the affective domain for 6th to 8th grade students with respect to the acquisition and transfer of social skills and values. Further, the extent that general classroom teachers and parents perceived if the learned skills where transferred to other context outside the PE class was examined in a sample of 274 students (ages 11 to 13 years old). One hundred and forty-five males (53%) and 129 females (47%) from five urban schools in Albacete Spain were studied. Three questionnaires were used (pre and post rating scales) as data collection instruments for students, teachers and parents. Results demonstrated encouraging estimates of reliability for the subscales of PE teachers’ perceptions of students’ values and regular education teaches perceptions with very strong values of internal consistency .82 and .93 respectively. Posttest values were slightly higher. Further, findings demonstrated positive outcomes after the intervention in teacher perceptions about students values levels (t =-8,05; p < .01), enjoyment, (t =-7.10; p < .01), fair play (t = -8.09; p < .01), social relation (t = -6.48; p < .01), good habits (t = -7.43; p < .01) and emotional control (t = -6.03; p < .01) in favor of the intervention group. These results support previous studies evidencing that integrating social skills and values intervention in the PE class increase students’ development in the affective domain.

description: We develop for the first time a mathematical framework in which the class of projection algorithms can be applied to high numerical aperture (NA) phase retrieval. Within this framework, we first analyze the basic steps of solving the high-NA phase retrieval problem by projection algorithms and establish the closed forms of all the relevant prox-operators. We then study the geometry of the high-NA phase retrieval problem and the obtained results are subsequently used to establish convergence criteria of projection algorithms in the presence of noise. Making use of the vectorial point-spread-function (PSF) is, on the one hand, the key difference between this paper and the literature of phase retrieval mathematics which deals with the scalar PSF. The results of this paper, on the other hand, can be viewed as extensions of those concerning projection methods for low-NA phase retrieval. Importantly, the improved performance of projection methods over the other classes of phase retrieval algorithms in the low-NA setting now also becomes applicable to the high-NA case. This is demonstrated by the accompanying numerical results which show that available solution approaches for high-NA phase retrieval are outperformed by projection methods.

description: We study cluster synchronization of networks and propose a canonical transformation for simultaneous block diagonalization of matrices that we use to analyze stability of the cluster synchronous solution. Our approach has several advantages as it allows us to: (1) decouple the stability problem into subproblems of minimal dimensionality while preserving physically meaningful information; (2) study stability of both orbital and equitable partitions of the network nodes and (3) obtain a parametrization of the problem in a small number of parameters. For the last point, we show how the canonical transformation decouples the problem into blocks that preserve key physical properties of the original system. We also apply our proposed algorithm to analyze several real networks of interest, and we find that it runs faster than alternative algorithms from the literature.

It intended to analyse the bone mineral density (BMD) of menopausal women through the bone densitometry test (DO) in the lumbar region (L1 to L4), femoral neck and total femur, and also use Bouchard’s self-recall of daily activities; employing the food record from Buker and Stuart to dose and quantify the daily intake of calcium and vitamin D. The data were analysed via Kolmogorov-Smirnov’s test, and default value of α = 0.05 was set to compare the BMD averages. It was observed that one hundred percent of the assessed individuals had a BMD level below the average fixed by WHO: 14.4% with osteopenia and 85.6% with osteoporosis; a lower BMD in the femoral area (0.721g) and the biggest loss among the sedentary ones (0.698g). It was noticed that there was a correlation between the physical activities and the BMD only when associated with anthropometric standards and the daily ingestion of vitamin D.

description: We study a system of $N_c$ $D3$-branes intersecting $D7$-branes and $O7$-planes in 1+1-dimensions. We use anomaly cancellation and string dualities to argue that there must be chiral fermion zero-modes on the $D3$-branes which are localized near the $O7$-planes. Away from the orientifold limit we verify this by using index theory as well as explicit construction of the zero-modes. This system is related to F-theory on K3 and heterotic matrix string theory, and the heterotic strings are related to Alice string defects in $\mathcal{N}=4$ Super-Yang-Mills. In the limit of large $N_c$ we find an $AdS_3$ dual of the heterotic matrix string CFT.

description: Vast sources of information, such as the Internet are difficult to browse and/or search through. Existing tools can be sometimes frustrating for many people. So far a number of techniques have been proposed to deliver user-oriented solutions. The problem re-surfaces however within a ubiquitous computing paradigm. Aside from a possible delay in response time, there are additional drawbacks with respect to mobile devices such as: Bandwidth size, storage(what type of costs do you mean) and performance costs and client UI size. In this paper we introduce three search and browsing features: fulltext search, collaborative filtering and multifaceted browsing, all of which can be enriched with se- mantic and community information. We present two of the aforementioned techniques implemented in our interface for digital libraries - DigiMe.
Reconstruction method in the kinetic gravity braiding theory with shift-symmetric

description: We present a reconstruction method for flat Friedman-Robertson-Walker (FRW) spacetime in a subclass of Horndeski theory -- specifically shiftsymmetric, the kinetic gravity braiding (KGB) theory with a non-vanishing conserved current. Choosing the form of the Hubble parameter and kinetic density $X$, we restore the functions $G_2$, $G_3$ of the KGB model. In order to determine whether the model is free of ghosts and Laplacian instabilities and thus cosmologically viable, two conditions related to scalar perturbations are checked. Initially, the Lagrangian does not include the term that describes, for example, the perfect fluid with the EoS parameter $w\neq -1$. This fluid can provide a dynamic solution $H(t)$, $X(t)$. In the presented method, dynamic solutions are provided by a nonzero scalar charge associated with the shift symmetry $ϕ\rightarrowϕ+ϕ_0$. Reconstruction examples are given for models: an perfect fluid, a unified description dark energy-dark matter, a post-inflationary transition to the radiation-dominated phase.

description: Single-molecule force spectroscopy experiments, as well as a number of other physical systems, are governed by thermally activated transitions out of a metastable state under the action of a steadily increasing external force. The main observable in such experiments is the distribution of the forces, at which the escape events occur. The challenge in interpreting the experimental data is to relate them to the microscopic system properties. We work out a maximum likelihood approach and show that it is the optimal method to tackle this problem. When fitting actual experimental data it is unavoidable to assume some functional form for the force-dependent escape rate. We consider a quite general and common such functional form and demonstrate by means of data from a realistic computer experiment that the maximum number of fit parameters that can be determined reliably is three. They are related to the force-free escape rate and the position and height of the activation barrier. Furthermore, the results for the first two of these fit parameters show little dependence on the assumption about the manner in which the barrier decreases with the applied force, while the last one, the barrier height in the absence of force, depends strongly on this assumption.

description: ``Geometric scaling'', i.e. the dependence of DIS cross-sections on the ratio Q/Q_S, where Q_S(Y) is the rapidity-dependent \saturation scale, can be theoretically obtained from universal ``traveling wave'' solutions of the nonlinear Balitsky-Kovchegov (BK) QCD evolution equation at fixed coupling. We examine the similar mean-field predictions beyond leading-logarithmic order, including running QCD coupling.

description: We analyze archived Chandra and XMM-Newton X-ray observations of 536 Sloan Digital Sky Survey (SDSS) Data Release 5 (DR5) quasars (QSOs) at 1.7 <= z <= 2.7 in order to characterize the relative UV and X-ray spectral properties of QSOs that do not have broad UV absorption lines (BALs). We constrain the fraction of X-ray weak, non-BAL QSOs and find that such objects are rare; for example, sources underluminous by a factor of 10 comprise $\la$2% of optically-selected SDSS QSOs. X-ray luminosities vary with respect to UV emission by a factor of $\la$2 over several years for most sources. UV continuum reddening and the presence of narrow-line absorbing systems are not strongly associated with X-ray weakness in our sample. X-ray brightness is significantly correlated with UV emission line properties, so that relatively X-ray weak, non-BAL QSOs generally have weaker, blueshifted CIV$λ$1549 emission and broader CIII]$λ$1909 lines. The CIV emission line strength depends on both UV and X-ray luminosity, suggesting that the physical mechanism driving the global Baldwin effect is also associated with X-ray emission.

description: We intended to determine the concurrent validity of a taekwondo specific anaerobic test (TSAT) to assess anaerobic fitness in taekwondo athletes. Seventeen elite male subjects (17.59 ± 4.34 years of age; 1.72 m ± .07 m in height; 61.3 kg ± 8.7 kg in weight and 15.6% ± 8.5% in body fat) performed a TSAT, which consisted of kicking a punching bag for 30 seconds. The standard test was the Wingate Anaerobic Test. Two trials were made for both tests and the agreement between both was tested. The variables analysed and compared were: peak power; relative peak power; mean anaerobic power; relative mean anaerobic power; fatigue index and anaerobic capacity. The number of kicks performed in the TSAT protocol and the maximum height of the counter movement jump (CMJ) were also registered. Trial I and II had significant ICC results in all variables (P = .000) ranged between 0.56 and 0.97. Both protocols were significantly correlated (r = 0.55 to 0.88; P = .000 to .05). CMJ strongly correlated with the number of techniques (r=0.59; P = .013) and the mean power (r = 0.56; P = .019) of the TSAT. The variables between the two methods correlate and are consistent, except for the anaerobic capacity that although correlated, is not consistent with constant bias, P = 0.001; CI]-705.1;-370.2[. TSAT has a level of agreement with the Wingate, and assigns specificity in the evaluation of these variables.

description: It is well known that in Lorentz invariant quantum field theories in flat space the commutator of space-like separated local operators vanishes (microcausality). We provide two different arguments showing that this is a consequence of the causal structure of the classical theory, rather than of Lorentz invariance. In particular, microcausality holds in arbitrary curved space-times, where Lorentz invariance is explicitly broken by the background metric. As illustrated by an explicit calculation on a cylinder this property is rather non trivial at the level of Feynman diagrams.
