description: Cathartes aura (Linnaeus, 1758) Records. Table 3. Turkey vulture individuals were identified by size, shape, and color pattern (Fig. 12). The body feathers were mostly brownish-black, but the flight feathers on the wings were silvery-gray underneath, contrasting with the darker wing linings. The head was small in proportion to the body and red in color with no feathers. This species also has a relatively short, hooked, ivory-colored beak. Its legs and feet are pink-skinned with white marks.

description: The properties of non-interacting $σ$ and $π^{0}$ mesons are studied at finite temperature, chemical potential and in the presence of a constant magnetic field. To do this, the energy dispersion relations of these particles, including nontrivial form factors, are derived using a derivative expansion of the effective action of a two-flavor, hot and magnetized Nambu--Jona-Lasinio (NJL) model up to second order. The temperature dependence of the pole and screening masses as well as the directional refraction indices of magnetized neutral mesons are explored for fixed magnetic fields and chemical potentials. It is shown that, because of the explicit breaking of the Lorentz invariance by the magnetic field, the refraction index and the screening mass of neutral mesons exhibit a certain anisotropy in the transverse and longitudinal directions with respect to the direction of the external magnetic field. In contrast to their longitudinal refraction indices, the transverse indices of the neutral mesons are larger than unity.

description: Observational studies of magnetic fields are vital as magnetic fields play a crucial role in various astrophysical processes, including star formation, accretion of matter, transport processes (e.g., transport of heat), and cosmic rays. We identified a process "ground state alignment" as a new way to determine the magnetic field direction in diffuse medium. The alignment is due to anisotropic radiation impinging on the atom/ion, while the magnetic field induces precession and realign the atom/ion and therefore the polarization of the emitted or absorbed radiation reflects the direction of the magnetic field. The atoms get aligned at their low levels and, as the life-time of the atoms/ions we deal with is long, the alignment induced by anisotropic radiation is susceptible to weak magnetic fields ($1{\rm G}\gtrsim B\gtrsim 10^{-15}$G). Compared to the upper level Hanle effect, atomic realignment is most suitable for the studies of magnetic field in the diffuse medium, where magnetic field is relatively weak. In fact, the effects of atomic/ionic alignment, including the realignment in magnetic field, were studied in the laboratory decades ago, mostly in relation to the maser research. Recently, the atomic effect has been already detected in observations from circumstellar medium and this is a harbinger of future extensive magnetic field studies. A unique feature of the atomic realignment is that they can reveal the 3D orientation of magnetic field. In this article, we shall review the basic physical processes involved in atomic realignment and its applications to interplanetary, circumstellar and interstellar magnetic fields. In addition, our research reveals that the polarization of the radiation arising from the transitions between fine and hyperfine states of the ground level can provide a unique diagnostics of magnetic fields, including those in the Early Universe.

description: We investigate the Majority-Vote Model with two states ($-1,+1$) and a noise $q$ on Apollonian networks. The main result found here is the presence of the phase transition as a function of the noise parameter $q$. We also studies de effect of redirecting a fraction $p$ of the links of the network. By means of Monte Carlo simulations, we obtained the exponent ratio $γ/ν$, $β/ν$, and $1/ν$ for several values of rewiring probability $p$. The critical noise was determined $q_{c}$ and $U^{*}$ also was calculated. The effective dimensionality of the system was observed to be independent on $p$, and the value $D_{eff} \approx1.0$ is observed for these networks. Previous results on the Ising model in Apollonian Networks have reported no presence of a phase transition. Therefore, the results present here demonstrate that the Majority-Vote Model belongs to a different universality class as the equilibrium Ising Model on Apollonian Network.

Smoking--Health aspects

description: Smoking was examined in relation to Parkinson's disease (PD) in a population-based study in northern Manhattan (New York City) because of its putative “protective effect.” Using a case-control design, information on smoking and associated behaviors was obtained in structured interviews after standard diagnostic evaluations in both cases and controls. The overall prevalence of smoking in the population was 43.7%, decreasing to 37% after age 85. Smoking was most frequent in men, Blacks, and in both cases and controls using alcohol once per week or more. Cases had quit smoking more often than controls (87 vs. 64%), and had smoked for significantly fewer years (31 vs. 41 yrs; p < 0.05 for both). The age-at-onset for smokers with PD was similar to age-at-onset for nonsmokers with PD. The odds ratio (OR) for a history of smoking associated with PD was 1.1 (95% CI 0.7–1.8). No protective gradient was associated with heavier smoking patterns. However, the odds that patients with PD were still smoking at the time of the interview were significantly less than those for controls (OR = 0.2; 95% CI 0.1–0.5). These results do not support the hypothesis that smoking protects against PD; rather they strongly imply the converse, that PD reduces smoking.

description: Transient withdrawal of therapy has been advocated as a method of dealing with the complications of long-term use of levodopa in the treatment of Parkinson's disease. We retrospectively examined the effect of a 10-day period of levodopa withdrawal, or "drug holiday," in 28 patients. We then compared the subsequent clinical course of these patients over one year with that of 30 other randomly selected, similar patients with Parkinson's disease. In both groups the disease progressed; there was no difference in disease severity, capacity for daily living activities, or total amounts of dopamine agonists eventually used. For some patients, it was possible to reduce dopamine agonists used immediately after the drug holiday without causing deterioration, but a pulmonary embolus and other complications occurred. Subsequent complications related to long-term dopamine-agonist therapy during the follow-up period were similar in the two groups. This investigation indicates that a drug holiday carries some risk and does not improve the efficacy of levodopa therapy or prevent the problems that occur with long-term administration.

description: Alternating between completing two simple tasks, as opposed to completing only one task, has been shown to produce costs to performance and changes to neural patterns of activity, effects which are augmented in old age. Cognitive conflict may arise from factors other than switching tasks, however. Sensorimotor congruency (whether stimulus-response mappings are the same or different for the two tasks) has been shown to behaviorally moderate switch costs in older, but not younger adults. In the current study, we used fMRI to investigate the neurobiological mechanisms of response-conflict congruency effects within a task switching paradigm in older (N=75) and younger (N=62) adults. Behaviorally, incongruency moderated age-related differences in switch costs. Neurally, switch costs were associated with greater activation in the dorsal attention network for older relative to younger adults. We also found that older adults recruited an additional set of brain areas in the ventral attention network to a greater extent than did younger adults to resolve congruency-related response-conflict. These results suggest both a network and an age-based dissociation between congruency and switch costs in task switching.

description: We consider the possibility that the cosmological dark matter consists of particles very close in mass to new colored particles below the TeV scale. While such a scenario is inherently difficult to directly confirm at colliders, we find that indirect dark matter searches may be a powerful alternative. In particular, we show that in this case dark matter annihilation to quark-quark-gluon final states can give rise to significant antiproton (but also gamma-ray) fluxes, and compare the resulting constraints to bounds from direct searches at LEP, the Tevatron and the LHC. For supersymmetric neutralinos degenerate with squarks, e.g., antiprotons can give rise to more stringent constraints for masses below around 45-80 GeV.

description: We investigate the phase structure of QCD at finite temperature and chemical potential by solving a coupled set of truncated Dyson-Schwinger equations for the quark and gluon propagator. In contrast to previous calculations we take into account the full back-reaction of the quarks onto the Yang-Mills sector and we include the effects of strange quarks. We discuss the resulting thermal mass of the unquenched gluon propagator and extract order parameters for the chiral and deconfinement transition from the quarks. Our result for the temperature dependence of the quark condensate at zero chemical potential agrees well with corresponding lattice calculations. We determine the phase diagram at finite chemical potential and find a potential critical endpoint at (mu_q,T) = (190,100) MeV.

description: Some recent results concerning the Sherrington-Kirkpatrick model are reported. For $T$ near the critical temperature $T_c$, the replica free energy of the Sherrington-Kirkpatrick model is taken as the starting point of an expansion in powers of $δQ_{ab} = (Q_{ab} - Q_{ab}^{\rm RS})$ about the Replica Symmetric solution $Q_{ab}^{\rm RS}$. The expansion is kept up to 4-th order in $δ{\bm Q}$ where a Parisi solution $Q_{ab} = Q(x)$ emerges, but only if one remains close enough to $T_c$. For $T$ near zero we show how to separate contributions from $x\ll T\ll 1$ where the Hessian maintains the standard structure of Parisi Replica Symmetry Breaking with bands of eigenvalues bounded below by zero modes. For $T\ll x \leq 1$ the bands collapse and only two eigenvalues, a null one and a positive one, are found. In this region the solution stands in what can be called a {\sl droplet-like} regime.

Design: Twenty HIV-positive subjects (12 without cognitive impairment and eight with mild cognitive impairment) and 10 HIV-negative subjects underwent neurological, neuropsychological, magnetic resonance imaging, and technetium Tc 99m exametazime SPECT examinations. Setting: Subjects were recruited from a natural history study of gay men with HIV infection. Patients: Subjects from the cohort who had previously participated in a magnetic resonance imaging study were selected for the SPECT study. Main Outcome Measures: The SPECT scans were rated as abnormal if focal defects, confirmed by a horizontal profile analysis, were seen. Results: Sixty-seven percent of HIV-positive subjects without cognitive impairment, 88% of HIV-positive subjects with mild cognitive impairment, and 20% of HIV-negative subjects had abnormal SPECT scans (P
Insights into human dynamic balance control : postural response initiation explored through classical conditioning and startle
Creators: name: Campbell, Adam Donald
Publisher: name: University of British Columbia
Year: 2012

description: As a scientific discipline, dynamic posturography aims to understand the neurological and biomechanical mechanisms that contribute to postural stability and corrective postural responses (PRs). The main focus of this thesis was to better understand the neurophysiology of corrective PRs that prevent falls that emerge from external forces applied to the body by balance perturbations. In a sequence of 4 studies, this thesis utilized novel applications of established techniques (classical conditioning and startle paradigms) to address questions regarding the role of sensory feedback in PRs initiation and the nature of PRs that are evoked by balance perturbations. The first of 4 experiments tested the link between sensory feedback derived by balance perturbations and PR initiation by attempting to trigger PRs using auditory cues that, prior to classical conditioning provided no relevant information pertaining to balance perturbations or postural stability. The second study examined the extent to which conditioned PRs may exist as prepared motor behaviours that could be initiated by startling acoustic stimuli in the absence of balance perturbations. The third study attempted to extend the previous findings of PR motor preparation into a more ecologically valid scenario involving unexpected balance perturbations. The fourth and final study in this thesis examined whether startle responses could contribute to first-trial effects observed on PRs evoked by the first in a repeated sequence of balance perturbations. Individually, each study provided highly novel contributions to the field of dynamic posturography. However, when taken together, they provide novel insight into both the mechanisms involved in PR initiation and the understanding of reactions evoked by balance perturbations.

description: In the context of the lattice regularization of the four-dimensional $\mathcal{N}=1$ supersymmetric Yang--Mills theory (4D $\mathcal{N}=1$ SYM), we formulate a generalized BRS transformation that treats the gauge, supersymmetry (SUSY), translation and axial U(1) ($U(1)_A$) transformations in a unified way. A resultant Slavnov--Taylor identity or the Zinn-Justin equation gives rise to a strong constraint on the quantum continuum limit of symmetry breaking terms with the lattice regularization. By analyzing the implications of the constraint on operator-mixing coefficients in the SUSY and the $U(1)_A$ Ward-Takahashi (WT) identities, we prove to all orders of perturbation theory in the continuum limit that, (i) the chiral symmetric limit implies the supersymmetric limit and, (ii) a three-fermion operator that might potentially give rise to an exotic breaking of the SUSY WT identity does not emerge. In previous literature, only a naive or incomplete treatment on these points can be found. Our results provide a solid theoretical basis for lattice formulations of the 4D $\mathcal{N}=1$ SYM.

description: We consider a multi-field open inflation model, in which one of the fields dominates quantum tunneling from a false vacuum while the other field governs slow-roll inflation within the bubble nucleated from false vacuum decay. We call the former the tunneling field and the latter the inflaton field. In the limit of a negligible interaction between the two fields, the false vacuum decay is described by a Coleman-De Luccia instanton. Here we take into account the coupling between the two fields and construct explicitly a multi-field instanton for a simple quartic potential model. We also solve the evolution of the scalar fields within the bubble. We find our model realizes open inflation successfully. This is the first concrete, viable model of open inflation realized with a simple potential. We then study the effect of the multi-field dynamics on the false vacuum decay, specifically on the tunneling rate. We find the tunneling rate increases in general in comparison with the single field case, though the increase is small unless the inflaton affects the instanton solution substantially.

title: Repeated observations of abrupt and persistent recruitment collapses in gadoids - a potential scenario in relation to climate change?

description: No abstracts are to be cited without prior reference to the author.Management, surveillance and studies of ecosystems and their constituent species are generally based on the assumption of simple dose-response relationships. Gradual environmental changes or perturbations are expected to cause corresponding changes in the abundance of affected species. However, a unique time series (since 1919) of 0-group gadoid abundance data from the Norwegian Skagerrak coast shows repeated incidents of abrupt and persistent recruitment collapses in gadoid fishes. It is proposed that the recruitment collapses are caused by gradually increasing nutrient loads, which result in abrupt changes in the planktonic community and thereby reduced food variability for the 0-group gadoids. The results suggest that: 1. There are alternative stable states with different environmental optima in marine ecosystems. 2. The change from one stable state to another appears as a catastrophic shift. 3. Different stable states may persist under overlapping environmental conditions, suggesting that marine ecosystems are highly resilient. 4. The eutrophication-induced shifts are linked to increasing turnover rates in the algal community with increasing primary productivity. This favours small, fast-growing algal species, which are then grazed by smaller herbivorous zooplankton. The fact that marine ecosystems may not respond in a gradual dose-response manner, but shift abruptly between alternative stable states seriously challenges our present approach of managing ecosystems and their constituent species, and the way we monitor potential impact of environmental changes. This is of particular concern at the prospect of global warming

description: Mirror dark matter interacting with ordinary matter via photon-mirror photon kinetic mixing can explain the DAMA, CoGeNT and CRESSTII direct detection experiments. This explanation requires kinetic mixing of strength $ε\sim 10^{-9}$. Such kinetic mixing will have important implications for early Universe cosmology. We calculate the additional relativistic energy density at recombination, $δN_{eff} [CMB]$. We also calculate the effects for big bang nucleosynthesis, $δN_{eff} [BBN]$. Current hints that both $δN_{eff} [CMB]$ and $δN_{eff} [BBN]$ are non-zero and positive can be accommodated within this framework if $ε\approx few \times 10^{-9}$. In the near future, measurements from the Planck mission will either confirm these hints or constrain $ε\stackrel{

description: The default-mode network (DMN) has become a well accepted concept in cognitive and clinical neuroscience over the last decade, and perusal of the recent literature attests to a stimulating research field of cognitive and diagnostic applications (for example, (Andrews-Hanna et al., 2010; Koch et al., 2010; Sheline et al., 2009a; Sheline et al., 2009b; Uddin et al., 2008; Uddin et al., 2009; Weng et al., 2009; Yan et al., 2009)). However, a formal definition of what exactly constitutes a functional brain network is difficult to come by. In recent contributions, some researchers argue that the DMN is best understood as multiple interacting subsystems (Buckner et al., 2008) and have explored modular components of the DMN that have different functional specialization and could to some extent be identified separately (Fox et al., 2005; Uddin et al., 2009). Such conception of modularity seems to imply an opposite construct of a 'unified whole', but it is difficult to locate proponents of the idea of a DMN who are supplying constraints that can be brought to bear on data in rigorous tests. Our aim in this paper is to present a principled way of deriving a single covariance pattern as the neural substrate of the DMN, test to what extent its behavior tracks the coupling strength between critical seed regions, and investigate to what extent our stricter concept of a network is consistent with the already established findings about the DMN in the literature. We show that our approach leads to a functional covariance pattern whose pattern scores are a good proxy for the integrity of the connections between a medioprefrontal, posterior cingulate and parietal seed regions. Our derived DMN network thus has potential for diagnostic applications that are simpler to perform than computation of pairwise correlational strengths or seed maps.
Strongly modulated transmissions in gapped armchair graphene nanoribbons with sidearm or on-site gate voltage

description: We propose two schemes of field-effect transistor based on gapped armchair graphene nanoribbons connected to metal leads, by introducing sidearms or on-site gate voltages. We make use of the band gap to reach excellent switch-off character. By introducing one sidearm or on-site gate to the graphene nanoribbon, conduction peaks appear inside the gap regime. By further applying two sidearms or on-site gates, these peaks are broadened to conduction plateaus with a wide energy window, thanks to the resonance from the dual structure. The position of the conduction windows inside the gap can be fully controlled by the length of the sidearms or the on-site gate voltages, which allows "on" and "off" operations for a specific energy window inside the gap regime. The high robustness of both the switch-off character and the conduction windows is demonstrated and shows the feasibility of the proposed dual structures for real applications.

These large terrestrial birds (Wc = 36.0 cm ± 1.1; n = 6) were very distinct due to several features, including the long and bright-red legs and brushy crest extending from the base of the upper red bill. Their body feathers were gray with shades of brown, and white on the abdomen; around the neck and underparts the plumage was loose; skin surrounding the eyes was blue; eyelash-like feathers around their eyes; wing and tail feathers with black and white bands.

description: Advancing age results in altered cognitive and neuroimaging-derived markers of neural integrity. Whether cognitive changes are the result of variations in brain measures remains unclear and relating the two across the lifespan poses a unique set of problems. It must be determined whether statistical associations between cognitive and brain measures truly exist and are not epiphenomenal due solely to their shared relationships with age. The purpose of this study was to determine whether cerebral blood flow (CBF) and gray matter volume (GMV) measures make unique and better predictions of cognition than age alone. Multivariate analyses identified brain-wide covariance patterns from 35 healthy young and 23 healthy older adults using MRI-derived measures of CBF and GMV related to three cognitive composite scores (i.e., memory, fluid ability, and speed/attention). These brain-cognitive relationships were consistent across the age range, and not the result of epiphenomenal associations with age and each imaging modality provided its own unique information. The CBF and GMV patterns each accounted for unique aspects of cognition and accounted for nearly all the age-related variance in the cognitive composite scores. The findings suggest that measures derived from multiple imaging modalities explain larger amounts of variance in cognition providing a more complete understanding of the aging brain.

description: The muon anomalous magnetic moment exhibits a 3.6 σdiscrepancy between experiment and theory. One explanation requires the existence of a light vector boson, Z_d (the dark Z), with mass 10 - 500 MeV that couples weakly to the electromagnetic current through kinetic mixing. Support for such a solution also comes from astrophysics conjectures regarding the utility of a U(1)_d gauge symmetry in the dark matter sector. In that scenario, we show that mass mixing between the Z_d and ordinary Z boson introduces a new source of "dark" parity violation which is potentially observable in atomic and polarized electron scattering experiments. Restrictive bounds on the mixing (m_{Z_d} / m_Z) δare found from existing atomic parity violation results, δ^2 < 2 x 10^{-5}. Combined with future planned and proposed polarized electron scattering experiments, a sensitivity of δ^2 ~ 10^{-6} is expected to be reached, thereby complementing direct searches for the Z_d boson.

Whose body? Nicholas and Sheila Pye's 'The Coronation'
Creators: name: Lawrence, Toby Katrine
Publisher: name: University of British Columbia
Year: 2012

description: In 2008, Canadian artists Nicholas and Sheila Pye travelled from Toronto, Ontario to Graz, Austria for a six-month artist residency. Working within the Austrian landscape and drawing from an influence of Northern European Medieval and Renaissance art the Pyes produced The Coronation, a twelve-minute, three-channel video installation enmeshed with art historical references. Their deliberate appropriation of the triptych format and the Adam and Eve imagery of the fifteenth-century Ghent Altarpiece by Jan van Eyck place the Edenic narrative of the side panels in The Coronation in conversation with the shifting seasons and ecological processes in the centre panel, providing numerous entry points for contemplation. While this video installation suggests an exploration of the iconographic body, it is also indicative of the Pyes’ complication of the notion of the autonomous human body, its engagement with the environment and, furthermore, an emphasis on the instability of identity. Previous writing on the collaborative practice of the Pyes has taken the form of exhibition reviews and curatorial essays, concentrating on a sustained narrative that prioritizes the Pyes’ relationship. Shifting away from the specificities of a biographical framework, my research focuses on The Coronation’s attention to the interrelationality of life. Furthermore, the Pyes push their artistic practice beyond one that assumes the specificity and autonomy of an individual human body, reconstituted in the intersecting body and earth. This informs our understanding of corporeal signification as comprised of embodied social and ideological performativity. Framed by a broad ecological lens and with Judith Butler’s notion of performativity in mind, I demonstrate the capacity of the Pyes’ work to problematize the stability of physical and enunciated boundaries that demarcate the human body.
