description: We measure the ellipticity of isolated clusters of galaxies in the Sloan Digital Sky Survey (SDSS) using gravitational lensing. We stack the clusters, rotating so that the major axes of the ellipses determined by the positions of cluster member galaxies are aligned. We exclude the signal from the central 0.5 h^-1 Mpc to avoid problems with stacking alignment and cluster member contamination. We fit an elliptical NFW profile and find an axis ratio for the dark matter of f = b/a = 0.48+0.14-0.09 (1 sigma), and rule out f=1 at 99.6 per cent confidence thus ruling out a spherical halo. We find that the ellipticity of the cluster galaxy distribution is consistent with being equal to the dark matter ellipticity. The results are similar if we change the isolation criterion by 50 per cent in either direction.

Does referential expectation guide both linguistic and social constraints on pronoun comprehension?
Creators: name: Langlois, Valerie J.

name: Arnold, Jennifer E.
Publisher: name: Elsevier
Year: 2023

description:
Current models suggest that pronoun comprehension is guided by expectations about who or what will be mentioned (Arnold, 1998; Kehler & Rohde, 2013; Hartshorne et al., 2015; Brocher et al., 2018), which we call referential predictability. Yet there is disagreement about whether these expectations explain all types of discourse biases, and in particular some scholars suggest that the subject bias is unrelated to referential predictability (Kehler & Rohde, 2013; Fukumura & van Gompel, 2015). Moreover, the role of expectation has not been broadly tested against the numerous constraints known to affect pronoun comprehension, and no study has tested whether expectation is related to social constraints like gaze and pointing. In eight experiments we systematically test how both pronoun comprehension and prediction judgments are influenced by four constraints: (1) the subject bias in joint-action predicates like Ana went hiking with Liz; (2) both the goal and subject biases in transfer predicates (Ana threw the ball to Liz or Ana got the ball from Liz); (3) pointing while gazing, and (4) gazing. We replicate and extend the known effects of these constraints on pronoun comprehension. Critically, we find that most of these constraints also affect prediction judgments, but the subject bias is inconsistent across verb types. Results support models in which referential expectation affects pronoun comprehension.
High mass-to-light ratios of UCDs - Evidence for dark matter ?

description: Ultra-compact dwarf galaxies (UCDs) are stellar systems with masses of around 10^7 to 10^8 Msun and half mass radii of 10-100 pc. They have some properties in common with massive globular clusters, however dynamical mass estimates have shown that UCDs have mass-to-light ratios which are on average about twice as large than those of globular clusters at comparable metallicity, and tend to be larger than what one would expect for old stellar systems with standard mass functions. One possible explanation for elevated high mass-to-light ratios in UCDs is the existence of a substantial amount of dark matter, which could have ended up in UCDs if they are the remnant nuclei of tidally stripped dwarf galaxies. Tidal stripping of dwarf galaxies has also been suggested has the origin of several massive globular clusters like Omega Cen, in which case globular clusters could have also formed with substantial amounts of dark matter. In this paper, we present collisional N-body simulations which study the co-evolution of a system composed out of stars and dark matter. We find that the dark matter gets removed from the central regions of such systems due to dynamical friction and mass segregation of stars. The friction timescale is significantly shorter than a Hubble time for typical globular clusters, while most UCDs have friction times much longer than a Hubble time. Therefore, a significant dark matter fraction remains within the half-mass radius of present-day UCDs, making dark matter a viable explanation for the elevated M/L ratios of UCDs. If at least some globular clusters formed in a way similar to UCDs, we predict a substantial amount of dark matter in their outer parts.

description: We study flavor violation in a supersymmetric SU(5) grand unification scenario in a model-independent way employing mass insertions. We examine how the quark and the lepton sector observables restrict sfermion mixings. With a low soft scalar mass, a lepton flavor violating process provides a stringent constraint on the flavor structure of right-handed down-type squarks. In particular, mu -> e gamma turns out to be highly susceptible to the 1-3 and 2-3 mixings thereof, due to the radiative correction from the top Yukawa coupling to the scalar mass terms of 10. With a higher scalar mass around the optimal value, in contrast, the quark sector inputs such as B-meson mixings and hadron electric dipole moment, essentially determine the room for sfermion mixing. We also discuss the recent deviation observed in B_s mixing phase, projected sensitivity of forthcoming experiments, and ways to maintain the power of leptonic restrictions even after incorporating a solution to fix the incorrect quark-lepton mass relations.

Self-similar solutions for the dynamical condensation of a radiative gas layer

description: A new self-similar solution describing the dynamical condensation of a radiative gas is investigated under a plane-parallel geometry. The dynamical condensation is caused by thermal instability. The solution is applicable to generic flow with a net cooling rate per unit volume and time $\propto ρ^2 T^α$, where $ρ$, $T$ and $α$ are density, temperature and a free parameter, respectively. Given $α$, a family of self-similar solutions with one parameter $η$ is found in which the central density and pressure evolve as follows: $ρ(x=0,t)\propto (t_\mathrm{c}-t)^{-η/(2-α)}$ and $P(x=0,t)\propto (t_\mathrm{c}-t)^{(1-η)/(1-α)}$, where $t_\mathrm{c}$ is an epoch when the central density becomes infinite. For $η\sim 0$, the solution describes the isochoric mode, whereas for $η\sim1$, the solution describes the isobaric mode. The self-similar solutions exist in the range between the two limits; that is, for $01$. We compare the obtained self-similar solutions with the results of one-dimensional hydrodynamical simulations. In a converging flow, the results of the numerical simulations agree well with the self-similar solutions in the high-density limit. Our self-similar solutions are applicable to the formation of interstellar clouds (HI cloud and molecular cloud) by thermal instability.

description: We study formation and evolution of bar-disk systems in fully self-consistent cosmological simulations of galaxy formation in the LCDM WMAP3 Universe. In a representative model we find that the first generation of bars form in response to the asymmetric dark matter (DM) distribution (i.e., DM filament) and quickly decay. Subsequent bar generations form and are destroyed during the major merger epoch permeated by interactions with a DM substructure (subhalos). A long-lived bar is triggered by a tide from a subhalo and survives for ~10 Gyr. The evolution of this bar is followed during the subsequent numerous minor mergers and interactions with the substructure. Together with intrinsic factors, these interactions largely determine the stellar bar evolution. The bar strength and its pattern speed anticorrelate, except during interactions and when the secondary (nuclear) bar is present. For about 5 Gyr bar pattern speed increases substantially despite the loss of angular momentum to stars and cuspy DM halo. We analyze the evolution of stellar populations in the bar-disk and relate them to the underlying dynamics. While the bar is made mainly of an intermediate age, ~5-6 Gyr, disk stars at z=0, a secondary nuclear bar which surfaces at z~0.1 is made of younger, ~1-3 Gyr stars.

description: To combine the high power efficiency of Continuous Phase Modulation (CPM) with either high spectral efficiency or enhanced performance in low Signal to Noise conditions, some authors have proposed to introduce CPM in a MIMO frame, by using Space Time Codes (STC). In this paper, we address the code design problem of Space Time Block Codes combined with CPM and introduce a new design criterion based on L2 orthogonality. This L2 orthogonality condition, with the help of simplifying assumption, leads, in the 2x2 case, to a new family of codes. These codes generalize the Wang and Xia code, which was based on pointwise orthogonality. Simulations indicate that the new codes achieve full diversity and a slightly better coding gain. Moreover, one of the codes can be interpreted as two antennas fed by two conventional CPMs using the same data but with different alphabet sets. Inspection of these alphabet sets lead also to a simple explanation of the (small) spectrum broadening of Space Time Coded CPM.

description: High-resolution observations provide evidence about the existence of small-amplitude transverse oscillations in solar filament fine structures. These oscillations are believed to represent fast magnetohydrodynamic (MHD) waves and the disturbances are seen to be damped in short timescales of the order of 1 to 4 periods. In this Letter we propose that, due to the highly inhomogeneous nature of the filament plasma at the fine structure spatial scale, the phenomenon of resonant absorption is likely to operate in the temporal attenuation of fast MHD oscillations. By considering transverse inhomogeneity in a straight flux tube model we find that, for density inhomogeneities typical of filament threads, the decay times are of a few oscillatory periods only.

description: We study Wilson loops in the three-dimensional N=6 supersymmetric Chern-Simons theory recently constructed by Aharony, Bergman, Jafferis and Maldacena, that is conjectured to be dual to type IIA string theory on AdS_4 x CP^3. We construct loop operators in the Chern-Simons theory which preserve 1/6 of the supercharges and calculate their expectation value up to 2-loop order at weak coupling. The expectation value at strong coupling is found by constructing the string theory duals of these operators. For low dimensional representations these are fundamental strings, for high dimensional representations these are D2-branes and D6-branes. In support of this identification we demonstrate that these string theory solutions match the symmetries, charges and the preserved supersymmetries of their Chern-Simons theory counterparts.

Type Systems for Distributed Programs:
Components and Sessions

Publisher: name: Alma Mater Studiorum - Università di Bologna

description: Modern software systems, in particular distributed ones, are everywhere around us and are at the basis of our everyday activities. Hence, guaranteeing their cor- rectness, consistency and safety is of paramount importance. Their complexity makes the verification of such properties a very challenging task. It is natural to expect that these systems are reliable and above all usable.
i) In order to be reliable, compositional models of software systems need to account for consistent dynamic reconfiguration, i.e., changing at runtime the communication patterns of a program.
ii) In order to be useful, compositional models of software systems need to account for interaction, which can be seen as communication patterns among components which collaborate together to achieve a common task.
The aim of the Ph.D. was to develop powerful techniques based on formal methods for the verification of correctness, consistency and safety properties related to dynamic reconfiguration and communication in complex distributed systems. In particular, static analysis techniques based on types and type systems appeared to be an adequate methodology, considering their success in guaranteeing not only basic safety properties, but also more sophisticated ones like, deadlock or livelock freedom in a concurrent setting.
The main contributions of this dissertation are twofold.
i) On the components side: we design types and a type system for a concurrent object-oriented calculus to statically ensure consistency of dynamic reconfigurations related to modifications of communication patterns in a program during execution time.
ii) On the communication side: we study advanced safety properties related to communication in complex distributed systems like deadlock-freedom, livelock- freedom and progress.
Most importantly, we exploit an encoding of types and terms of a typical distributed language, session π-calculus, into the standard typed π- calculus, in order to understand their expressive power.

description: We consider the solution of the subset sum problem based on a parallel computer consisting of self-propelled biological agents moving in a nanostructured network that encodes the NP-complete task in its geometry. We develop an approximate analytical method to analyze the effects of small errors in the nonideal junctions composing the computing network by using a Gaussian confidence interval approximation of the multinomial distribution. We concretely evaluate the probability distribution for error-induced paths and determine the minimal number of agents required to obtain a proper solution. We finally validate our theoretical results with exact numerical simulations of the subset sum problem for different set sizes and error probabilities.

description: To study the nuclear ($\lesssim1\,$kpc) dust of nearby ($z<0.1$) type 1 Quasi Stellar Objects (QSOs) we obtained new near-infrared (NIR) high angular resolution ($\sim0.3$ arcsec) photometry in the H and Ks bands, for 13 QSOs with available mid-infrared (MIR) high angular resolution spectroscopy ($\sim7.5-13.5\,μ$m). We find that in most QSOs the NIR emission is unresolved. We subtract the contribution from the accretion disk, which decreases from NIR ($\sim35\%$) to MIR ($\sim2.4\%$). We also estimate these percentages assuming a bluer accretion disk and find that the contibution in the MIR is nearly seven time larger. We find that the majority of objects ($64\%$, 9/13) are better fitted by the Disk+Wind H17 model \citep[][]{Hoenig17}, while others can be fitted by the Smooth F06 \citep[$14\%$, 2/13,][]{Fritz06}, Clumpy N08 \citep[$7\%$, 1/13,][]{Nenkova08a,Nenkova08b}, Clumpy H10 \citep[$7\%$, 1/13,][]{Hoenig10b}, and Two-Phase media S16 \citep[$7\%$, 1/13,][]{Stalev16} models. However, if we assume the bluer accretion disk, the models fit only 2/13 objects. We measured two NIR to MIR spectral indexes, $α_{NIR-MIR(1.6,8.7\,μ\text{m})}$ and $α_{NIR-MIR(2.2,8.7\,μ\text{m})}$, and two MIR spectral indexes, $α_{MIR(7.8, 9.8\,μ\text{m})}$ and $α_{MIR(9.8, 11.7\,μ\text{m})}$, from models and observations. From observations, we find that the NIR to MIR spectral indexes are $\sim-1.1$ and the MIR spectral indexes are $\sim-0.3$. Comparing the synthetic and observed values, we find that none of the models simultaneously match the measured NIR to MIR and $7.8-9.8\,μ$m slopes. However, we note that measuring the $α_{MIR(7.8, 9.8\,μ\text{m})}$ on the starburst-subtracted {\it Spitzer}/IRS spectrum, gives values of the slopes ($\sim-2$) that are similar to the synthetic values obtained from the models.

description:
Extreme weather events are occurring more frequently and with increased intensity owing to the changing climate. Climate change has both direct and indirect impacts on human health that are unevenly distributed among the global population and compounded by negative social determinants of health, such as economic instability and limited health care access. Vulnerable groups are disproportionately exposed to extreme heat and severe storms as a result of climate change. Ethnic and racial minorities, indigenous groups, low-income populations, the elderly, pregnant women, children, and those with unstable housing or lack of access to utilities such as air-conditioning are especially vulnerable. Neighborhood- and community-level characteristics that increase susceptibility to the adverse health effects of climate change are also associated with higher allergic disease prevalence and severity.

The effect of reproductive condition on sexual behaviour and the olfactory bulb electroencephalogram in male goldfish
Creators: name: Goff, Robert
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study was to investigate the mechanism(s) of the preference of sexually mature male goldfish for sexually mature female goldfish. First, the effect of reproductive condition on the sexual behaviour of male goldfish was examined to determine the mechanism(s) of the behavioural preference of mature males for mature females. Second, the effect of reproductive condition of the male on the response of the olfactory bulb electroencephalogram (EEG) to biological olfactory stimuli was examined for the electrophysiological correlates of the behavioural mechanism(s). The sexual behaviour of male goldfish is affected by reproductive condition. Regressed male goldfish do not demonstrate sexual behaviour. The sexual behaviour of mature male goldfish appears to be regulated by two mechanisms. A general tendency of the mature male to chase female goldfish seems to be regulated by an all-or-none mechanism which is activated when spermiation (release of sperm into the sperm duct) occurs in the male. A second mechanism appears to regulate the preference of mature male goldfish for sexually mature female goldfish. The preference for mature females is not directly dependent on spermiation since mature (spermiated) males with gonadosomatic indices (GSI) below 3.5 do not chase mature females preferentially. Mature males with a GSI above 3.5 chase mature females significantly more than regressed females, and a marked peak in the preference for mature females is observed for males with GSIs of 3.5-4.0. An earlier behavioural study suggested that the preference of mature males is a response to a pheromone from the mature females. Therefore, it might be expected that the neural activity of the olfactory system of mature male goldfish would respond differentially to an olfactory stimulus derived from mature female goldfish. The electrophysiological studies of this thesis indicate that a selective response to the stimulus derived from mature females is not evident in the olfactory bulb EEG of mature males. However, the amplitudes of the spontaneous EEG and the responses of the EEG to olfactory stimuli are significantly greater in the olfactory bulb of mature male goldfish than in that of regressed male goldfish. The EEG amplitude is correlated with the maturation of the testes, and gonadal hormones and/or other hormones may affect the EEG. The significance of the increase in EEG amplitude with reproductive condition is discussed in relation to the mechanisms of sexual behaviour.

description: Density-functional theory within a Berry-phase formulation of the dynamical polarization is used to determine the second-order susceptibility $χ^{(2)}$ of lithium niobate (LiNbO$_3$). Defect trapped polarons and bipolarons are found to strongly enhance the nonlinear susceptibility of the material, in particular if localized at Nb$_\mathrm{V}$-V$_{\mathrm{Li}}$ defect pairs. This is essentially a consequence of the polaronic excitation resulting in relaxation-induced gap states. The occupation of these levels leads to strongly enhanced $χ^{(2)}$ coefficients and allows for the spatial and transient modification of the second-harmonic generation of macroscopic samples.

description: Stereoscopic projection mapping (PM) allows a user to see a three-dimensional (3D) computer-generated (CG) object floating over physical surfaces of arbitrary shapes around us using projected imagery. However, the current stereoscopic PM technology only satisfies binocular cues and is not capable of providing correct focus cues, which causes a vergence--accommodation conflict (VAC). Therefore, we propose a multifocal approach to mitigate VAC in stereoscopic PM. Our primary technical contribution is to attach electrically focus-tunable lenses (ETLs) to active shutter glasses to control both vergence and accommodation. Specifically, we apply fast and periodical focal sweeps to the ETLs, which causes the "virtual image'" (as an optical term) of a scene observed through the ETLs to move back and forth during each sweep period. A 3D CG object is projected from a synchronized high-speed projector only when the virtual image of the projected imagery is located at a desired distance. This provides an observer with the correct focus cues required. In this study, we solve three technical issues that are unique to stereoscopic PM: (1) The 3D CG object is displayed on non-planar and even moving surfaces; (2) the physical surfaces need to be shown without the focus modulation; (3) the shutter glasses additionally need to be synchronized with the ETLs and the projector. We also develop a novel compensation technique to deal with the "lens breathing" artifact that varies the retinal size of the virtual image through focal length modulation. Further, using a proof-of-concept prototype, we demonstrate that our technique can present the virtual image of a target 3D CG object at the correct depth. Finally, we validate the advantage provided by our technique by comparing it with conventional stereoscopic PM using a user study on a depth-matching task.

3d gravity in Bondi-Weyl gauge: charges, corners, and integrability

description: We introduce a new gauge and solution space for three-dimensional gravity. As its name Bondi-Weyl suggests, it leads to non-trivial Weyl charges, and uses Bondi-like coordinates to allow for an arbitrary cosmological constant and therefore spacetimes which are asymptotically locally (A)dS or flat. We explain how integrability requires a choice of integrable slicing and also the introduction of a corner term. After discussing the holographic renormalization of the action and of the symplectic potential, we show that the charges are finite, symplectic and integrable, yet not conserved. We find four towers of charges forming an algebroid given by $\mathfrak{vir}\oplus\mathfrak{vir}\oplus\text{Heisenberg}$ with three central extensions, where the base space is parametrized by the retarded time. These four charges generate diffeomorphisms of the boundary cylinder, Weyl rescalings of the boundary metric, and radial translations. We perform this study both in metric and triad variables, and use the triad to explain the covariant origin of the corner terms needed for renormalization and integrability.

description: We consider the Higgs sector of multi-Higgs-doublet models in the presence of simple symmetries relating the various fields. We construct basis invariant observables which may in principle be used to detect these symmetries for any number of doublets. A categorization of the symmetries into classes is required, which we perform in detail for the case of two and three Higgs doublets.

description: Blazars are a subclass of radio-loud active galactic nuclei (AGNs), where the jet is aligned close to the line of sight. Blazars emission is dominated by non-thermal processes, where Doppler boosted radiation originates from a relativistic population of charged particles within the jet. From radio to TeV energies, blazars are highly variable on timescales from minutes to several months. There are several mechanisms proposed to explain variability, including changes in the viewing angle of the jet, propagating along the rotation axis of the accretion disc. The misalignment of a supermassive black hole (SMBH) spin and the angular momentum of the accretion disc yields to Lense-Thirring precession of such tilted disc, which leads to the variation of Doppler beaming. Such scenario is supported by radio observations of jet precession observed in some AGNs. The radio-emitting regions, however, are located far from the central engine, and thus the observed time scales in this band can be affected by e.g. a variation of the bulk Lorentz factor along the jet. In this contribution, we derive expected time scales of the jet wobbling using SMBH masses and compare them with the time intervals between flares in long-term (over 15 years) X-ray light curves of bright blazars observed by Swift-XRT. We found that for Mrk 421, Mrk 501 and 3C 273, the derived time scales are consistent with the observational constraints, while for 1ES 1959+650 we are mostly limited by uncertainty in the Doppler beaming factor.

description:
BACKGROUND: Informal caregivers (e.g., partners, other family members, friends) often provide social support to Black women with breast cancer, and caregivers find both benefits and challenges in their caregiving role. METHODS: In this qualitative study, twenty-four caregivers for Black women with breast cancer participated in focus groups and interviews. Participants responded to a brief close-ended questionnaire as well as semi-structured questions about their experiences as cancer caregivers. Demographic information was collected, and relationship satisfaction was measured by the Relationship Assessment Scale-General scale (RAS-G). Focus groups and interviews were recorded, transcribed verbatim, and coded by two independent coders. Using an iterative, discussion-based process, the study team developed and refined themes. RESULTS: All caregivers described themselves as Black/African American, and the majority identified as female (79%). The mean RAS-G score was 4.5 (SD = 0.5), indicating high levels of relationship satisfaction. Qualitative themes included using a range of strategies to provide emotional support; shifting between roles; needing time and space; and trying to stay strong. Several female caregivers described how the cumulative experiences of providing care for multiple family members and friends could be draining, as could their own experiences in the patient role. CONCLUSIONS: These findings show a complex, multilayered social context that affects both the patient-caregiver relationship and the health and wellbeing of caregivers. Clinicians providing treatment and support for Black women with breast cancer should be mindful of how the health context of the family may affect patient and caregiver outcomes.

description: The late evolutionary stages of low- and intermediate-mass stars are characterised by mass loss through a dust-driven stellar wind. Recent observations reveal complex structures within these winds, that are believed to be formed primarily via interaction with a companion. How these complexities arise, and which structures are formed in which type of systems, is still poorly understood. Particularly, there is a lack of studies investigating the structure formation in eccentric systems. We aim to improve our understanding of the wind morphology of eccentric AGB binary systems by investigating the mechanism responsible for the different small-scale structures and global morphologies that arise in a polytropic wind with different velocities. Using the smoothed particle hydrodynamics (SPH) code Phantom, we generate nine different high-resolution, 3D simulations of an AGB star with a solar-mass companion with various wind velocity and eccentricity combinations. The models assume a polytropic gas, with no additional cooling. We conclude that for models with a high wind velocity, the short interaction with the companion results in a regular spiral morphology, that is flattened. In the case of a lower wind velocity, the stronger interaction results in the formation of a high-energy region and bow-shock structure that can shape the wind into an irregular morphology if instabilities arise. High-eccentricity models show a complex, phase-dependent interaction leading to wind structures that are irregular in three dimensions. However, the significant interaction with the companion compresses matter into an equatorial density enhancement, irrespective of eccentricity.
