CMB Polarization towards Clusters as a Probe of the Integrated Sachs-Wolfe Effect

Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The scattering of temperature anisotropy quadrupole by free electrons in galaxy clusters leads to a now well-known polarization signal in the cosmic microwave background (CMB) fluctuations. Using multi-frequency polarization data, one can extract the temperature quadrupole and separate it from the contaminant polarization associated with the kinematic quadrupole due to transverse motion of clusters. At low redshifts, the temperature quadrupole contains a significant contribution from the integrated Sachs-Wolfe effect (ISW) associated with the growth of density fluctuations. Using polarization data from a sample of clusters over a wide range in redshift, one can statistically establish the presence of the ISW effect and determine the redshift dependence of the ISW contribution to the rms quadrupole. Given the strong dependence of the ISW effect on the background cosmology, the cluster polarization can eventually be used as a probe of the dark energy.

description: This study examines the role of the decision stage in the recognition of reduced pronunciation variants, specifically variants produced with nasal flaps (e.g. “counter” produced as “couner”). We investigate whether the previously reported disadvantage for nasally flapped variants is located at an early perceptual processing stage or at a post-perceptual decision stage. Experiment 1 replicates the variant effect with a lexical decision task. Experiment 2 uses the psychological refractory period paradigm, suggesting that the variant effect is located at a stage that requires central processing resources. Experiment 3 employed the shadowing task, indicating a significantly smaller variant effect compared to the lexical decision task. In concert, our results suggest that the disadvantage for nasally flapped variants has at least in part a decisional locus, which challenges representational and perceptual accounts of the effect. A mechanism is discussed that describes how decisional factors could cause the disadvantage for reduced variants.

description: With the observations of SDO/AIA 304 Å and NVST Hα bands, we present the formation process of an active-region filament in active region NOAA 11903 during the period from 02:00 UT to 10:00 UT on November 25, 2013. A series of jets occurring in the vicinity of the south-western footpoint of the filament directly ejected cool and hot plasma to filament height and supplied material for the filament. Some newly emerging flux is found in the vicinity of the filament south-western footpoint during these jets. In this paper, we mainly focus on the material supply of the filament. The plasma mass uploaded by the jets and the mass of the filament are estimated, which manifests the fact that the mass carried by jets can supply sufficient material for the formation of the filament. We found two types of jets. one is H-alpha jet, and the other is EUV jet. The significant finding is that some cool jets seen in the Hα band but not in the SDO/AIA bands also could eject the cool material for the filament. These results suggest that cool plasma in the low atmosphere can be directly injected into the upper atmosphere and become the filament material by two types of jets. Moreover, the newly emerging flux with non-potential field plays an important role in the appearances of the jets and the magnetic structure of the filament.

description: The proton and neutron electromagnetic form factors and the nucleon axial form factor have been calculated in the Goldstone-boson exchange constituent-quark model within the point-form approach to relativistic quantum mechanics. The results, obtained without any adjustable parameter nor quark form factors, are, due to the dramatic effects of the boost required by the covariant treatment, in striking agreement with the data.

description: The flavor $ud$ and $us$ pseudoscalar correlators are investigated using families of finite energy sum rules (FESR's) known to be very accurately satisfied in the isovector vector channel. It is shown that the combination of constraints provided by the full set of these sum rules is sufficiently strong to allow determination of both the light quark mass combinations $m_u+m_d$, $m_s+m_u$ and the decay constants of the first excited pseudoscalar mesons in these channels. The resulting masses and decay constants are also shown to produce well-satisfied Borel transformed sum rules, thus providing non-trivial constraints on the treatment of direct instanton effects in the FESR analysis. The values of $m_u+m_d$ and $m_s+m_u$ obtained are in good agreement with the values implied by recent hadronic $τ$ decay analyses and the ratios obtained from ChPT. New light quark mass bounds based on FESR's involving weight functions which strongly suppress spectral contributions from the excited resonance region are also presented.

description: Reprocessed X-ray radiation carries important information about the structure and physical characteristics of the material surrounding the supermassive black hole (SMBH) in active galactic nuclei (AGN). We report here on a newly developed simulation platform, RefleX, which allows to reproduce absorption and reflection by quasi-arbitrary geometries. We show here the reliability of our approach by comparing the results of our simulations with existing spectral models such as pexrav, MYTorus and BNTorus. RefleX implements both Compton scattering on free electrons and Rayleigh scattering and Compton scattering on bound electrons. We show the effect of bound-electron corrections on a torus geometry simulated like in MYTorus. We release with this paper the RefleX executable, as well as RXTorus, a model that assumes absorption and reflection from a torus with a varying ratio of the minor to major axis of the torus. To allow major flexibility RXTorus is also distributed in three components: absorbed primary emission, scattered radiation and fluorescent lines. RXTorus is provided for different values of the abundance, and with (atomic configuration) or without (free-electron configuration) taking into account Rayleigh scattering and bound electrons. We apply the RXTorus model in both configurations on the XMM-Newton and NuSTAR spectrum of the Compton-thick AGN NGC 424 and find that the models are able to reproduce very well the observations, but that the assumption on the bound or free state of the electrons has significant consequences on the fit parameters.

description: Matching skills supply and demand is critical for economic growth, competitiveness and inclusiveness. Yet, measuring skills is difficult. This paper develops an approach for measuring the gap between demand and supply of skills at the local level in the UK West Midlands region. It uses qualifications as a proxy for skills. By comparing the projected supply of qualifications with the forecast demand for qualifications from occupational forecasts, the analysis reveals significant skill mismatches with potential to constrain regional growth potential. Policy implications for connecting skills, transport and housing policy as part of local industrial strategies are explored.

description: This paper argues that e-skills – capabilities associated with the use and development of digital technologies – enhance regions’ ability to draw on existing know-how and create new industrial paths. The empirical analysis focuses on the relationship between e-skills and technological diversification for a panel of European regions in the period 2000–12. It constructs novel indices of regional e-skill endowment distinguishing between basic users, professional users and expert developers of information and communication technologies. The econometric results show that e-skills foster technological diversification dynamics in European regions, and that this effect is particularly strong for less-developed regions, and for low levels of relatedness.

Neutrino Masses in Theories with Dynamical Electroweak Symmetry Breaking

Year: 2002
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We address the problem of accounting for light neutrino masses in theories with dynamical electroweak symmetry breaking. We discuss this in the context of a class of (extended) technicolor (ETC) models and analyze the full set of Dirac and Majorana masses that arise in such theories. As a possible solution, we propose a combination of suppressed Dirac masses and a seesaw involving dynamically generated $|ΔL|=2$ condensates of standard-model singlet, ETC-nonsinglet fermions. We show how this can be realized in an explicit ETC model. An important feature of this proposal is that, because of the suppression of Dirac neutrino mass terms, a seesaw yielding realistic neutrino masses does not require superheavy Majorana masses; indeed, these Majorana masses are typically much smaller than the largest ETC scale.

description: We study the fluctuations of the Gaussian model, with conservation of the order parameter, evolving in contact with a thermal bath quenched from inverse temperature $β_i$ to a final one $β_f$. At every time there exists a critical value $s_c(t)$ of the variance $s$ of the order parameter per degree of freedom such that the fluctuations with $s>s_c(t)$ are characterized by a macroscopic contribution of the zero wavevector mode, similarly to what occurs in an ordinary condensation transition. We show that the probability of fluctuations with $s\inf _t [s_c(t)]$, induces a slow non-equilibrium dynamics resembling that of systems quenched across a phase transition.

description: This paper examines the role played by spatial spillovers in shaping the regional distribution of quality of government across the European Union. To do so, it constructs a hybrid spatial weights matrix combining geographical, technological and social distances between the European regions. The results reveal that the quality of government in neighbouring regions has a positive and statistically significant effect on one region’s quality of government, which highlights the relevance of spatial effects in this context. This finding is robust to the inclusion in the analysis of different variables that may affect regional governance. Likewise, the observed effect of neighbouring regions does not depend on the specific dimension of governance considered, the spatial weights matrix used to describe the spatial linkages between the European regions, or the econometric specification employed to capture the nature of spatial spillovers. The results also show that policy innovations related to governance spread from regions with high and intermediate levels of quality of government.
Correlations of Richness and Global Properties in Galaxy Clusters

description: We measure the optical richness of galaxy clusters from the CNOC1 cluster redshift survey using the galaxy-cluster center correlation amplitude B_gc. We show that the B_gc values measured using photometric catalogs are consistent with those derived from redshift catalogs, indicating that richness can be measured reliably from photometric data alone, even at moderate redshifts of \~0.6. We establish the correlations between optical richness and other important attributes of a galaxy cluster, such as velocity dispersion, mass, radius, and X-ray temperature and luminosity. We find that the scaling relations of these quantities with richness are entirely consistent with those derived by assuming a simple mass density profile at 0.5 Mpc of rho~r^{-1.8}. The excellent correlations between B_gc and velocity dispersion and X-ray temperature allow one to use richness, an easily measurable quantity using relatively shallow optical imaging data alone, as a predictor of these quantities at moderate redshifts. The B_gc parameter can be used to estimate the velocity dispersion of a cluster to a precision of approximately 15% (~+/-100 km/s), and X-ray temperature to about 20%. Similar correlations, but with larger scatter, are also obtained between richness and the characteristic radius and mass of the clusters. We compare the relative merits of B_gc, T_x, and L_x as predictors of the dynamical mass, and find that they are comparable, providing estimates at an accuracy of ~30%. We also perform similar analyses of correlations between richness and velocity dispersion, T_x and L_x with a sample of low-redshift Abell clusters and find consistent results, but with larger scatter, which may be the result of a less homogeneous database, or sample-dependent effects.

description: Due to low activity and poor wettability of carbon fiber (CF), the interaction between CF and polyphenylene sulfide (PPS) matrix is weak, which decreases the mechanical properties of CF reinforced PPS （CF/PPS） composites. In this article, the interfacial adhesion of CF/PPS composites was strengthened by using a water-soluble poly (amic acid) ammonium salt (PAAs) as sizing agent. This PAAs-based sizing agent had good compatibility with PPS and formed hydrogen bonds with CF activated by Meldrum’s acid. Significantly, the PAAs sizing agent can be soluble in water (up to 20 wt % high solid content) without organic solvents and surfactants, which shows huge potential in industrial applications. Experimental results demonstrated that the interlaminar shear strength (ILSS), flexural strengths, and moduli of modified CF/PPS composites increased by 19.5%, 24.9%, and 10.1%, respectively. According to the SEM images on fractured surfaces of composites, fiber and PPS resin were tightly packed, and the failure mechanism was interface deformation or resin breakage.

description: At a low resolution scale with $Q^2=μ^2$ corresponding to the nucleon bound state; deep inelastic unpolarized structure functions $F_1(x,μ^2)$ and $F_2(x,μ^2)$ are derived with correct support using the symmetric part of the hadronic tensor under some simplifying assumptions in the Bjorken limit. For doing this; the nucleon in its ground state has been represented by a suitably constructed momentum wave packet of its valence quarks in their appropriate SU(6) spin flavor configuration with the momentum probability amplitude taken phenomenologically in reference to the independent quark model of scalar-vector harmonic potential. The valence quark distribution functions $u_v(x,μ^2)$ and $d_v(x,μ^2)$, extracted from the structure function $F_1(x,μ^2)$ in a parton model interpretation, satisfy normalization constraints as well as the momentum sum-rule requirements at a bound state scale of $μ^2=0.1 GeV^2$. QCD evolution of these distribution functions taken as the inputs; yields at $Q_0^2=15 GeV^2; xu_v(x,Q_0^2)$ and $xd_v(x,Q_0^2)$ in good qualitative agreement with the experimental data. The gluon distribution $G(x,Q_0^2)$ and the sea-quark distribution $q_s(x,Q_0^2)$; which are dynamically generated using the leading order renormalization group equation; also match reasonably well with the available experimental data.

description: One of the simplest examples of a robust heteroclinic cycle involves three saddle equilibria: each one is unstable to the next in turn, and connections from one to the next occur within invariant subspaces. Such a situation can be described by a third-order ordinary differential equation (ODE), and typical trajectories approach each equilibrium point in turn, spending progressively longer to cycle around the three points but never stopping. This cycle has been invoked as a model of cyclic competition between populations adopting three strategies, characterised as Rock, Paper and Scissors. When spatial distribution and mobility of the populations is taken into account, waves of Rock can invade regions of Scissors, only to be invaded by Paper in turn. The dynamics is described by a set of partial differential equations (PDEs) that has travelling wave (in one dimension) and spiral (in two dimensions) solutions. In this paper, we explore how the robust heteroclinic cycle in the ODE manifests itself in the PDEs. Taking the wavespeed as a parameter, and moving into a travelling frame, the PDEs reduce to a sixth-order set of ODEs, in which travelling waves are created in a Hopf bifurcation and are destroyed in three different heteroclinic bifurcations, depending on parameters, as the travelling wave approaches the heteroclinic cycle. We explore the three different heteroclinic bifurcations, none of which have been observed in the context of robust heteroclinic cycles previously. These results are an important step towards a full understanding of the spiral patterns found in two dimensions, with possible application to travelling waves and spirals in other population dynamics models.

description: We consider the contribution of a two-loop Barr-Zee type diagram to $(g-2)_μ$ in the minimal supersymmetric standard model (MSSM). At relatively large $\tanβ$, we show that the contribution of light third generation scalar fermions and neutral CP-even Higgs, $h^0(H^0)$, can easily explain the very recent BNL experimental data. In our analysis $(g-2)_μ$ prefers negative $A_{f}$ and positive $μ$. It is more sensitive to the chirality flipping $h^0(H^0)\wt{f}_R^*\wt{f}_L$ rather than chirality conserving couplings.

description: Airports are an important factor of regional connectivity. Following the literature, a sufficiently dense airport network is an important determinant for growth. However, regional airports in Germany exhibit financial losses and depend on subsidies. This paper analyses the potential spillover effects of airports on the surrounding economies that may justify those subsidies by exploiting the deregulation of the European aviation market as a quasi-natural experiment. Subsequent airport expansions are evaluated in a difference-in-differences framework, making use of the exogenous shift in airport demand for regional airports due to the deregulation. Results show no evidence for spillover effects of Germany's regional airports.
Missing Mass and the Acceleration of the Universe. Is Quintessence the only Explanation?

description: Detailed observations of the temperature fluctuations in the microwave background radiation indicate that we live in an open universe. From the size of these fluctuations it is concluded that the geometry of the universe is quite close to Euclidean. In terms Friedmann models, this implies a mass density within 10% of the critical density required for a flat universe. Observed mass can only account for 30% of this mass density. Recently, an outstanding observation revealed that cosmos is accelerating. This motivated some astronomers to explain the missing 70% as some exotic dark energy called quintessence. In this essay, we present an alternative explanation to these cosmological issues in terms of the Friedmann Thermodynamics. This model has the capability of making definite predictions about the geometry of the universe, the missing mass problem, and the acceleration of the universe in-line with the recent observations. For future observations, we also predict where this model will start differing from the quintessence models.

description: Preparing for the expected wealth of Gaia detections, we consider here a simple algorithm for classifying unresolved astrometric binaries with main-sequence (MS) primary into three classes: binaries with a probable MS secondary, with two possible values for the mass ratio; probable hierarchical triple MS systems with an astrometric secondary as a close binary, with a limited range of mass-ratio values; and binaries with a compact-object secondary, with a minimal value of the mass ratio. This is done by defining a unit-less observational parameter 'Astrometric Mass-Ratio Function' (AMRF), $\mathcal{A}$, of a binary, based on primary-mass estimation, in addition to the astrometric parameters - the angular semi-major axis, the period and the parallax. We derive the $\mathcal{A}$ value that differentiates the three classes by forward modeling representative binaries of each class, assuming some mass-luminosity relation.To demonstrate the potential of the algorithm, we consider the orbits of 98 Hipparcos astrometric binaries with main-sequence primaries, using the Hipparcos parallaxes and the primary-mass estimates. For systems with known spectroscopic orbital solution, our results are consistent with the spectroscopic elements, validating the suggested approach. The algorithm will be able to identify hierarchical triple systems and dormant neutron-star and black-hole companions in the Gaia astrometric binaries.

description: Triple-negative breast cancer (TNBC) is a heterogeneous and clinically aggressive disease with no approved targeted therapy. Curcumin has shown therapeutic potential against TNBC, but it shows low bioavailability and low efficacy when administered as a free drug. Here we describe a novel vehicle for in vivo delivery of curcumin based on the phosphorylated calixarene POCA4C6. Curcumin-loaded POCA4C6 micelles (CPM) were prepared using the thin-film method and they showed a unilamellar structure with an average particle size of 3.86 nm. The micelles showed high curcumin encapsulation efficiency and loading was based on liquid chromatography-tandem mass spectrometry. Studies with cell cultures suggest that CPM can sustainably release curcumin in a pH-dependent manner. The micelles efficiently inhibited proliferation, invasion, migration and tumor spheroid formation by BT-549 human breast cancer cells. These effects involved increased apoptosis and reduced levels of nuclear β-catenin and androgen receptor. After injection into tumor xenografts, CPM persisted in the tumor tissue and efficiently inhibited tumor growth without causing obvious systemic toxicity. CPM also significantly reduced levels of CD44+/CD133+ breast cancer stem cells. Our results highlight the potential of CPM as an effective therapy against TNBC.

Fine Structure Constant Variation from a Late Phase Transition

description: Recent experimental data indicates that the fine structure constant alpha may be varying on cosmological time scales. We consider the possibility that such a variation could be induced by a second order phase transition which occurs at late times (z ~ 1 - 3) and involves a change in the vacuum expectation value (vev) of a scalar with milli-eV mass. Such light scalars are natural in supersymmetric theories with low SUSY breaking scale. If the vev of this scalar contributes to masses of electrically charged fields, the low-energy value of alpha changes during the phase transition. The observational predictions of this scenario include isotope-dependent deviations from Newtonian gravity at sub-millimeter distances, and (if the phase transition is a sharp event on cosmological time scales) the presence of a well-defined step-like feature in the alpha(z) plot. The relation between the fractional changes in alpha and the QCD confinement scale is highly model dependent, and even in grand unified theories the change in alpha does not need to be accompanied by a large shift in nucleon masses.

description: Cluster policies pervade all regions of the world to promote employment growth, innovation and entrepreneurship. Yet, research mostly focuses on cluster economic performance, but less on regional social cohesion, which is important when economic growth coexists with deprivation, poverty and inequality. The paper’s aim is to understand both the economic and the social dynamics of clusters by developing a theoretical model based on system dynamics. It shows that clusters with positive economic performance do not necessarily lead to regional social cohesion. Multiple positive economic-related feedback processes can be mitigated by negative social-related feedback processes. Implications for academics and policy-makers are proposed.

 Xylosandrus abruptulus (Schedl): Schedl, 1964, Reichenbachia 2: 213.
 This endemic species was described from specimens collected in Queensland (Wongabel) from a species of mistletoe (Loranthus sp.) (Schedl 1953). Zimmerman (1992) has photographs of dorsal and lateral views. (It may be noted that the references under this species in Wood and Bright (1992) to ‘‘ Browne 1968 b:720’’ refer in fact to Xylosandrus abruptoides (Schedl), a species which is now considered to be a synonym of Xylosandrus morigerus (Blandford).) We have examined paralectotypes in NHML, and more than 80 specimens in QMB and RAB. All were collected in North and Northeast Queensland between 15 ° 43 9 S and 19 ° 07 9 S, and 145 ° 17E and 146 ° 23 9 E, at altitudes from 650 m – 1,360 m, the majority at 1,000 m or above. The species seems to be confined to the remnants of the montane rainforest. No further host records are available, but, like most other ambrosia beetles, the species probably normally breeds in a wide variety of dead and dying trees, and is unlikely to be confined to Loranthus.

description: A latent class model is applied to allow entrepreneurial ecosystems (EEs) to influence the effect of entrepreneurial activity on growth in European Union regions. Using this methodology, clusters of regions that differ significantly in their relationship between entrepreneurial activity and growth are identified. This is consistent with the hypothesis that EEs affect this relationship. Subsequently, cluster membership is related to regional characteristics representing a range of components of EEs and marked differences in a variety of these regional characteristics are found. Taken together, the results support the notion that EEs help shape the impact of entrepreneurial activity on growth.

 Diagnosis
Eye absent; rostrum short, acute; antenna 1 elongate, about 1.5×length of body, peduncle 3 very short, accessory flagellum very long, about 0.3×length of primary flagellum; antenna 2 about 0.3×length of antenna 1, flagellum short; upper lip, weakly incised, symmetric; mandible, incisors slightly asymmetric, palp strong, threearticulate; maxilliped, inner plate not reaching base of palp, outer plate nearly reaching base of article 2 of palp, palp four-articulate, powerful; gnathopods dissimilar, gnathopod 1 large, propodus strongly tapering, stout, weakly subchelate; gnathopod 2, propodus small, subchelate; peraeopods 3–4 gracile, ischium extremely elongated, almost as long as basis; peraeopods 5–6 subequal; peraeopod 7 dissimilar to peraeopods 5–6, very long, slender, about as long as body; epimeron 2–3 with a posteroventral tooth; urosomite 1, with a posterodorsal, bidentate tooth; urosomite 2, with a slender, posterodorsal tooth; uropods 1–2, lanceolate, very long, more than 2×length of the urosome and strongly spinose; uropod 3, rami elongate, subequal, outer ramus two-articulate, article 2 minute; telson short, slightly longer than wide, lateral margins parallel, cleft v-shaped about 55%, lobes acute.
 Type species Macroarthrus victoriae sp. nov. by monotypy.
 Etymology
 The genus name is from the Greek makros (long) and arthrus (joint), referring to the immensely elongated ischium of peraeopods 3 and 4.
 Remarks
 Macroarthrus has a wealth of unique characters. The extreme elongation of the ischium of peraeopods 3 and 4 is remarkable and highly distinctive, a character previously unknown in the Gammaridea. The Lysianassoidea possess an elongated ischium of gnathopod 2, but not of peraeopods 3 and 4. Hyperiopsidae have an elongated merus of peraeopods 3 and 4, but the ischium is very short.
 Macroarthrus differs from all pardaliscids in the following combination of characters: maxilla 1, inner plate with four apical setae; dissimilar, stout gnathopods with gnathopod 1 the larger; antenna 1 very long, about 3×antenna 2, accessory flagellum extremely long, about 0.25×the length of antenna 1, 18-articulate; peraeopod 7, strongly dissimilar and elongated relative to peraeopods 5 and 6 and the elongated, strongly spinose uropods.
