Azimuthal dependence of the density distribution in outer galactic discs accreting intergalactic flows

description: AIMS. The amplitude and scaleheight of the Galactic gas disc density are not axisymmetric against expectations in a self-gravity axisymmetric disc. However, this lopsidedness can be explained in terms of intergalactic accretion flows, which produce non-axisymmetric pressure on the disc. This mechanism could be also responsible for the formation of a warp. METHODS. We analytically derive the relationship between the disc density and the self-gravity and external pressure. RESULTS. The same scenario of accretion as we proposed years ago to explain the formation of the warp explains the azimuthal dependence of the density and its scaleheight, with minimum/maximum in the positions of maximum amplitude of the warp (phi=95 deg. and 275 deg.), as expected from its pressure distribution.

description: We report on the linear and nonlinear optical response of metamaterials evoked by first and second order multipoles. The analytical ground on which our approach bases permits for new insights into the functionality of metamaterials. For the sake of clarity we focus here on a key geometry, namely the split-ring resonator, although the introduced formalism can be applied to arbitrary structures. We derive the equations that describe linear and nonlinear light propagation where special emphasis is put on second harmonic generation. This contribution basically aims at stretching versatile and existing concepts to describe light propagation in nonlinear media towards the realm of metamaterials.

description: The aim of this work is the development of a method to operate elementary spin excitations (magnons) in a ferromagnetic metal by means of elementary vibrational excitations of the lattice (phonons). The utilized magnon-phonon coupling was confirmed more than 50 years ago, but only recently the experimental approaches of ultrafast acoustics have made available the excitation and time-resolved detection of coherent phonons in the sub-THz frequency range. The most intriguing regime of the magnon-phonon coupling is the strong coupling regime, which guarantees a conversion of phonons to magnons and vice versa at unity fidelity. This regime is extremely difficult to achieve in ferromagnetic metals due to a typically weak magnon-phonon coupling and fast relaxation processes. In this work, we demonstrate a way to overcome these limitations and to achieve the regime of strong magnon-phonon coupling. We have utilized a lateral nanoscale pattering (nanograting) of a Galfenol nanolayer, in order to introduce two additional localized high-Q phonon modes (~ 10 GHz). By means of an in-plane external magnetic field, we control the frequency detuning between the magnon and phonons modes, while their spatial overlap is determined by the lateral pattern. We observe two bright manifestations of the magnon-phonon coupling, i.e. resonant phonon driving and avoided crossing. The latter one clearly indicates the regime of strong magnon-phonon coupling with formation of a hybridized state known as magnon polaron. Theoretically, the magnon-phonon coupling is considered in the frame of coupled oscillators, whose coupling strength is determined by the spatial overlap of the interacting modes. The presented experimental and theoretical results may aid in the development of energy-efficient transducers between magnonic and phononic systems.
On the Dark Matter Solutions to the Cosmic Ray Lepton Puzzle
Creators: name: Brun, Pierre
Publisher: name: arXiv
Year: 2009
Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)
subject: FOS: Physical sciences

description: Recent measurements of cosmic ray leptons by PAMELA, ATIC, HESS and Fermi revealed interesting excesses. Many authors suggested particle Dark Matter (DM) annihilations could be at the origin of these effects. In this paper, we critically assess this interpretation by reviewing some results questioning the naturalness and robustness of such an interpretation. Natural values for the DM particle parameters lead to a poor leptons production so that models often require signal enhancement effects that we constrain here. Considering DM annihilations are likely to produce antiprotons as well, we use the PAMELA antiproton to proton ratio measurements to constrain a possible exotic contribution. We also consider the possibility of an enhancement due to a nearby clump of DM. This scenario appears unlikely when compared to the state-of-the-art cosmological N-body simulations. We conclude that the bulk of the observed signals most likely has no link with DM and is rather a new, yet unconsidered source of background for searches in these channels.

description: We report on recent results in the study of extremal black hole attractors in N=2, d=4 ungauged Maxwell-Einstein supergravities. For homogeneous symmetric scalar manifolds, the three general classes of attractor solutions with non-vanishing Bekenstein-Hawking entropy are discussed. They correspond to three (inequivalent) classes of orbits of the charge vector, which sits in the relevant symplectic representation R_{V} of the U-duality group. Other than the 1/2-BPS one, there are two other distinct non-BPS classes of charge orbits, one of which has vanishing central charge. The complete classification of the U-duality orbits, as well as of the moduli spaces of non-BPS attractors (spanned by the scalars which are not stabilized at the black hole event horizon), is also reviewed. Finally, we consider the analogous classification for N>2-extended, d=4 ungauged supergravities, in which also the 1/N-BPS attractors yield a related moduli space.

Interaction and gas outflows in radio-loud AGN - Disruptive and constructive effects of radio jets

description: In the last years, Active Galactic Nuclei (AGN) have become more popular than ever. The possibility of using them to produce feedback effects that would help solving some of the still open questions connected to the hierarchical scenario of galaxy formation and evolution, has made them particularly popular among theorists. AGN-driven outflows can have different origin. Here, I will concentrate on the role that the radio-loud phase of nuclear activity (and the presence of radio plasma jets) can play in the evolution of a galaxy. I will focus on two aspects in which radio activity could be important. The first is exploring whether relativistic plasma jet associated with radio-loud galaxies could provide an effective way to produce gas outflows with characteristics that can be relevant in the evolution of the host galaxy. The second, is to investigate whether they can provide a mechanism for the triggering of star formation.

The evolution of German social democracy
Creators: name: Kopsch, Hartmut
Publisher: name: University of British Columbia
Year: 2011

description: It is the purpose of this thesis to study the evolution of German Social Democracy from its early origin as a "social-movement party" to its development as a "modern pragmatic party" in the post-1945 period. This investigation of the Social Democratic Party of Germany (SPD) utilized both party documents and a wide selection of secondary material. The study was divided into three periods, each of which represented a fairly distinctive stage in the evolution of the SPD. In the early period (1890-1913) it was suggested that the SPD evolved from a "social-movement party" to an "aspiring Volkspartei" (people's party). The transition was indicated by a gradual shift in the emphasis placed on Social Democratic goals. Increasing concentration on electoral victory and a decreasing emphasis on Social Democratic ideology characterized the SPD's evolution in the early period. In the second period (1914-1933) party leaders sought to extend the influence of Social Democracy in the state, and attempted to escape from the electoral consequences of sn exclusively working-class orientation. An examination of the goals pursued by the SPD leadership indicated that efforts were made to convert the SPD into a genuine Volkspartei. An attempt was made to discover why SPD leaders failed to secure this objective. Party leaders failed to transform the SPD into a genuine VoIkspartei primarily because the intensity of ideological cleavages in German society prevented any political party from gaining substantial support from all electorally significant social groups. An examination of the goals pursued by Social Democratic leaders in the third period (post-1945) suggested that the SPD developed as a "categorical opposition party" under the leadership of Kurt Schumacher. By 1960, however, the SPD was no longer recognizable as "Schumacher's party" and had adopted a programme and a strategy which were based on one overriding goal — political power. The SPD's emergence as a pragmatic political party was indicated by the willingness of party leaders to subject considerations of principle or ideology to the goal of attaining responsibility for the over-all conduct of government.

description: We study the final architecture of planetary systems that evolve under the combined effects of planet-planet and planetesimal scattering. Using N-body simulations we investigate the dynamics of marginally unstable systems of gas and ice giants both in isolation and when the planets form interior to a planetesimal belt. The unstable isolated systems evolve under planet-planet scattering to yield an eccentricity distribution that matches that observed for extrasolar planets. When planetesimals are included the outcome depends upon the total mass of the planets. For system masses exceeding about one Jupiter mass the final eccentricity distribution remains broad, whereas for lower mass planetary systems a combination of divergent orbital evolution and recircularization of scattered planets results in a preponderance of nearly circular final orbits. We also study the fate of marginally stable multiple planet systems in the presence of planetesimal disks, and find that for high planet masses the majority of such systems evolve into resonance. A significant fraction lead to resonant chains that are planetary analogs of Jupiter's Galilean satellites. We predict that a transition from eccentric to near-circular orbits will be observed once extrasolar planet surveys detect sub-Jovian mass planets at orbital radii of 5-10 AU.

As a consequence, we obtain that the fundamental group of M cannot be isomorphic to the fundamental group of any Riemannian manifold of nonpositive sectional curvature. In particular, M is a locally CAT(0)-manifold which does not support any Riemannian metric of nonpositive sectional curvature.

Subjects: Firefighters, Musculoskeletal Disorders, Ergonomic Risk Factors, Qec (Quick Exposure Check), Nordic Musculoskeletal Questionnaire.

description: Abstract

Background: Musculoskeletal disorder is defined as damage to the musculoskeletal system, which includes the muscles, tendons, ligaments, nerves, discs, blood vessels, and other components that allow the human body to move. Firefighting is an unsafe and arduous physically. Firefighters work in emergencies to prevent and cease fire and respond to disaster. Therefore they are at increased risk for developing musculoskeletal disorder. Objective: To investigate the prevalence of musculoskeletal disorders and ergonomic risk factors among firefighters. Methodology: Nordic musculoskeletal questionnaire was used to report musculoskeletal disorders in 106 firefighters and quick exposure check (QEC) questionnaire was used in 20 firefighters for 3 different tasks to evaluated the ergonomic risk factors. Results: 37% of firefighters experienced low back pain as major pain in last 12 months. Followed by shoulder and neck pain. Low back pain (28%) along with knee pain(22%) caused trouble in working in last 12 months. Task of lifting ladders on shoulder was the major ergonomic risk factor for developing musculoskeletal disorders as compared to holding up hose and folding the hose task. Conclusion: High prevalence was shown in low back, knees, neck and shoulder. Lifting up ladders on shoulder task leads to ergonomic risk for development of musculoskeletal disorders.

description: In this work, the structural and magnetic properties of the gold-coated FePt nanoparticles synthesized from high-temperature solution phase are presented. The amount of gold was optimized to obtain most of the FePt particles coated. The particle diameter increases from 4 to 10 nm as observed by TEM. The magnetic properties are largely affected by the coating. At low temperature, the coercive field Hc of the coated nanoparticles decreases about three times respect to the uncoated and the blocking temperature reduces to the half. The changes of the magnetic behavior are discussed in terms of the effect of the gold atoms at the FePt core surface.

Importance of coincidence in entomophagous insects with particular reference to certain parasites of Neodiprion serfifer (Geoff.).
Creators: name: Griffiths, Kenneth John
Publisher: name: University of British Columbia
Year: 2011

description: This study represents the first of its kind to evaluate the importance of spatial and temporal co= incidence between parasitic insects and their insect hosts. Extensive and intensive field observations here demonstrate that lack of coincidence is possible between the European pine sawfly, Neodiprion sertifer Geoff. and its three most important parasites. In the ichneumonids, Exenterus canadensis Prov., spatial coincidence is nearly perfect, while temporal coincidence may be poor. The bombyliid, Villa sinuosa (Wd.) shows imperfect spatial coincidence, but good temporal coincidence. In the ichneumonid Pleolophus basizonus (Grav.) both spatial and temporal coincidence may be imperfect. The degress of coincidence are related to the physiology of development and the behaviour of the parasites and their host in their variable environmental contexts. The interrelations of host density, parasite density, time of contacts, number of eggs laid, and number of hosts attacked, were studied experimentally with P. basizonus. The results were more closely described by the predictions of the Holling than of the Watt equation. The distribution of eggs in hosts was more often adequately described by the negative binomial than the Poisson equation for probabilities. The effect of asynchrony in the species studied cannot be considered without reference to superparasitisms. At low host densities superparasitism largely buffers effects of decreased synchrony, but its buffering diminishes to an asymptote as host density increases. In any given generation, imperfect spatial coincidence has little effect where attack is asymptotic. Simulations of host-parasite interactions over 25 to 35 host generations showed that for P. basizonus and E. Canadensis, host and parasite populations would become stable after passing through one or more oscillations even when, temporal and spatial coincidence are reduced. Predictions for V. sinuosa indicate its inability to restrain host populations even at perfect coincidence.
Compassionate Care in a Crisis Resolution and Home Treatment Setting: A Thematic Analysis

description: Background: Compassion has been positioned as an integral element of healthcare delivery (Care Quality Commission, 2011) and service users have highlighted the need for increased compassion in crisis resolution and home treatment team (CRT) settings. Despite this, it remains unclear how the term ‘compassionate care’ is understood by CRT stakeholders, and how it can be consistently actualised at individual and service levels. Aims: This study aims to elucidate CRT staff conceptualisations of compassionate care, as well as the perceived barriers to, and facilitators of compassionate care within a CRT setting. Methodology: This qualitative study used individual, semi-structured interviews to explore staff conceptualisations of compassionate crisis care, and the facilitators and barriers to this in a crisis team setting. Twelve CRT staff members took part in the study. The resultant data were analysed using reflexive thematic analysis. Results: Four main themes and several related subthemes were generated from the study data. The main themes were: Going the Extra Mile; The Operation of Social Power; Centrality of Team Processes; and The Balancing Act. Conclusions: The findings provide an insight into CRT staff members’ understanding and experience of compassionate care in crisis teams. Compassionate crisis care was characterised as involving an ethos of ‘going the extra mile’ in various ways, such as through efforts at creating consistency in CRT care. The findings also highlight the importance of attending to compassionate crisis care as a complex, relational phenomenon, involving dynamics of social power. Further, processes within the team, and the tension caused by several dilemmas, such as the risk of perpetuating CRT dependence, were highlighted as central to understanding the generation and sustenance of compassionate crisis care. Overall, participants highlighted the need to understand and facilitate compassionate crisis care provision from organisational, service and policy levels, as well as at individual and relational levels.

description: [Abridged] To simulate the kinds of observations that will eventually be obtained for exoplanets, the Deep Impact spacecraft obtained light curves of Earth at seven wavebands spanning 300-1000 nm as part of the EPOXI mission of opportunity. In this paper we analyze disc-integrated light curves, treating Earth as if it were an exoplanet, to determine if we can detect the presence of oceans and continents. We present two observations each spanning one day, taken at gibbous phases. The rotation of the planet leads to diurnal albedo variations of 15-30%, with the largest relative changes occuring at the reddest wavelengths. To characterize these variations in an unbiased manner we carry out a principal component analysis of the multi-band light curves; this analysis reveals that 98% of the diurnal color changes of Earth are due to only 2 dominant eigencolors. We use the time-variations of these two eigencolors to construct longitudinal maps of the Earth, treating it as a non-uniform Lambert sphere. We find that the spectral and spatial distributions of the eigencolors correspond to cloud-free continents and oceans; this despite the fact that our observations were taken on days with typical cloud cover. We also find that the near-infrared wavebands are particularly useful in distinguishing between land and water. Based on this experiment we conclude that it should be possible to infer the existence of water oceans on exoplanets with time-resolved broadband observations taken by a large space-based coronagraphic telescope.

description: Kaasaegsete aju-uurijate huviorbiidis on olnud domineerivalt negatiivsed ilmingud nagu raev, ärevus, hirm. See on ka loomulik, sest hirmu aluseks olevad närvivõrgustikud tagasid loomariigis ellujäämise ja on evolutsiooni käigus tugevalt kinnistunud. Õnneks on viimasel  ajal hakatud rohkem tähelepanu pöörama ka positiivsetele tunnetele (1). Üheks enam ihaldatud tundeks on ilmselgelt armastus. Kuni praeguseni ei peeta küll terminit „armastus“ teaduslikuks mõisteks, kuid seda deﬁ  neeritakse  osavalt teaduslike terminite abil. Levinud väljendiks selle seisundi kirjeldamisel on näiteks „nende keemia sobib“. Tõsi see on, et ühe osa eest selle tunde arengus vastutavad tõesti organismi nanopeptiidid oksütotsiin ja vasopressiin. Mõlemad peptiidid sünteesitakse paraventrikulaarses ja supraoptilises tuumas hüpotalamuses ja projektsiooniteed lõpevad neurohüpofüüsis. Nanopeptiidid reguleerivad reproduktiivset käitumist, olles  orgastilise elamuse saamise oluliseks teguriks (2). Heaolutunde ootust ja selle saabumist vahendab dopamiin. Romantilise armastuse mõistet ei saa samastada seksuaalse kirega. Viimase puhul on keemilised muutused organismis seotud pigem suguhormoonidega ning selle tunde olemus ja eesmärk on teine.

description: Using high-resolution collisionless N-body simulations we study the properties of tidal tails formed in the immediate vicinity of a two-component dwarf galaxy evolving in a static potential of the Milky Way (MW). The stellar component of the dwarf is initially in the form of a disk and the galaxy is placed on an eccentric orbit motivated by CDM-based cosmological simulations. We measure the orientation, density and velocity distribution of the stars in the tails. Due to the geometry of the orbit, in the vicinity of the dwarf, where the tails are densest and therefore most likely to be detectable, they are typically oriented towards the MW and not along the orbit. We report on an interesting phenomenon of `tidal tail flipping': on the way from the pericentre to the apocentre the old tails following the orbit are dissolved and new ones pointing towards the MW are formed over a short timescale. We also find a tight linear relation between the velocity of stars in the tidal tails and their distance from the dwarf. Using mock data sets we demonstrate that if dwarf spheroidal (dSph) galaxies in the vicinity of the MW are tidally affected their kinematic samples are very likely contaminated by tidally stripped stars which tend to artificially inflate the measured velocity dispersion. The effect is stronger for dwarfs on their way from the peri- to the apocentre due to the formation of new tidal tails after pericentre. Realistic mass estimates of dSph galaxies thus require removal of these stars from kinematic samples.

description: Tänapäeval teostatakse maailmas üle 2000 kopsutransplantatsiooni aastas. Peamisteks näidustusteks on lõppstaadiumis krooniline obstruktiivne kopsuhaigus, α1-antitrüpsiini puudulikkus, idiopaatiline kopsufibroos ja tsüstiline fibroos. Esmaseks kopsutransplantatsiooni eesmärgiks on haigete eluea pikendamine, teisel olulisel kohal on elukvaliteedi parandamine. Tulenevalt haigusest, patsiendi vanusest jm teguritest kasutatakse nii ühe kui ka kahe kopsu transplantatsiooni. Doonorelundid kopsutransplantatsiooniks saadakse peamiselt ajusurmas doonoritelt. Tüsistusteta kulu korral on transplantatsioonijärgse haiglaravi kestuseks 3–4 nädalat. Järgneb elukestev ambulatoorne jälgimine eesmärgiga korraldada immunosupressiivset ravi ja diagnoosida ning ravida võimalikke tüsistusi. Keskmine 5 aasta elulemus pärast kopsutransplantatsiooni on tänapäeval üle 50%.

description: The major obstacle in applying peptides to intracellular targets is their low inherent cell permeability. Standard approaches to attach a fluorophore (e.g. FITC, TAMRA) can change the physicochemical properties of the parent peptide and influence their ability to penetrate and localize in cells. We report a label-free strategy for evaluating the cell permeability of cyclic peptide leads. Fluorescent tryptophan analogues 4-cyanotryptophan (4CNW) and beta-(1-azulenyl)-L-alanine (AzAla) were incorporated into in vitro translated macrocyclic peptides by initiator reprogramming. We then demonstrate these efficient blue fluorescent emitters are good tools for monitoring peptide penetration into cells.

description: We perform an extensive test of theoretical stellar models for main-sequence stars in ugriz, using cluster fiducial sequences obtained in the previous paper of this series. We generate a set of isochrones using the Yale Rotating Evolutionary Code (YREC) with updated input physics, and derive magnitudes and colors in ugriz from MARCS model atmospheres. These models match cluster main sequences over a wide range of metallicity within the errors of the adopted cluster parameters. However, we find a large discrepancy of model colors at the lower main sequence (Teff < ~4500 K) for clusters at and above solar metallicity. We also reach similar conclusions using the theoretical isochrones of Girardi et al. and Dotter et al., but our new models are generally in better agreement with the data. Using our theoretical isochrones, we also derive main-sequence fitting distances and turn-off ages for five key globular clusters, and demonstrate the ability to derive these quantities from photometric data in the Sloan Digital Sky Survey. In particular, we exploit multiple color indices (g - r, g - i, and g - z) in the parameter estimation, which allows us to evaluate internal systematic errors. Our distance estimates, with an error of sigma(m - M) = 0.03-0.11 mag for individual clusters, are consistent with Hipparcos-based subdwarf fitting distances derived in the Johnson-Cousins or Stromgren photometric systems.

description: We perform a quark model calculation of the quarkonia $b\overline{b}$ and $c\overline{c}$ spectra using smooth and sudden string breaking potentials. The screening parameter is scale dependent and can be related to an effective running gluon mass that has a finite infrared fixed point. A temperature dependence for the screening mass is motivated by lattice QCD simulations at finite temperature. Qualitatively different results are obtained for quarkonia properties close to a critical value of the deconfining temperature when a smooth or a sudden string breaking potential is used. In particular, with a sudden string breaking potential quarkonia radii remain almost independent of the temperature up to the critical point, only well above the critical point the radii increase significantly. Such a behavior will impact the phenomenology of quarkonia interactions in medium, in particular for scattering dissociation processes.
