Galaxy And Mass Assembly (GAMA): Mid-Infrared Properties and Empirical
  Relations from $WISE$

The Galaxy And Mass Assembly (GAMA) survey furnishes a deep redshift catalog
that, when combined with the Wide-field Infrared Explorer ($WISE$), allows us
to explore for the first time the mid-infrared properties of $> 110, 000$
galaxies over 120 deg$^2$ to $z\simeq 0.5$. In this paper we detail the
procedure for producing the matched GAMA-$WISE$ catalog for the G12 and G15
fields, in particular characterising and measuring resolved sources; the
complete catalogs for all three GAMA equatorial fields will be made available
through the GAMA public releases. The wealth of multiwavelength photometry and
optical spectroscopy allows us to explore empirical relations between optically
determined stellar mass (derived from synthetic stellar population models) and
3.4micron and 4.6micron WISE measurements. Similarly dust-corrected
Halpha-derived star formation rates can be compared to 12micron and 22micron
luminosities to quantify correlations that can be applied to large samples to
$z<0.5$. To illustrate the applications of these relations, we use the 12micron
star formation prescription to investigate the behavior of specific star
formation within the GAMA-WISE sample and underscore the ability of WISE to
detect star-forming systems at $z\sim0.5$. Within galaxy groups (determined by
a sophisticated friends-of-friends scheme), results suggest that galaxies with
a neighbor within 100$\,h^{-1} $kpc have, on average, lower specific star
formation rates than typical GAMA galaxies with the same stellar mass.Comment: 20 pages. Accepted to Ap
Dependence of the outer density profiles of halos on their mass
  accretion rate

We present a systematic study of the density profiles of LCDM halos, focusing
on the outer regions, 0.1 < r/Rvir < 9. We show that the median and mean
profiles of halo samples of a given peak height exhibit significant deviations
from the universal analytic profiles discussed previously in the literature,
such as the Navarro-Frenk-White and Einasto profiles, at radii r > 0.5 R200m.
In particular, at these radii the logarithmic slope of the median density
profiles of massive or rapidly accreting halos steepens more sharply than
predicted. The steepest slope of the profiles occurs at r ~ R200m, and its
absolute value increases with increasing peak height or mass accretion rate,
reaching slopes of -4 and steeper. Importantly, we find that the outermost
density profiles at r > R200m are remarkably self-similar when radii are
rescaled by R200m. This self-similarity indicates that radii defined with
respect to the mean density are preferred for describing the structure and
evolution of the outer profiles. However, the inner density profiles are most
self-similar when radii are rescaled by R200c. We propose a new fitting formula
that describes the median and mean profiles of halo samples selected by their
peak height or mass accretion rate with accuracy < 10% at all radii, redshifts
and masses we studied, r < 9 Rvir, 0 < z < 6 and Mvir > 1.7E10 Msun/h. We
discuss observational signatures of the profile features described above, and
show that the steepening of the outer profile should be detectable in future
weak-lensing analyses of massive clusters. Such observations could be used to
estimate the mass accretion rate of cluster halos.Comment: 18 pages, 18 figures. Published version, minor change
Mixed quantal-semiquantal dynamics with stochastic particles for
  backreaction

A mixed quantal-semiquantal theory is presented in which the semiquantal
squeezed-state wave packet describes the heavy degrees of freedom. We first
derive mean-field equations of motion from the time-dependent variational
principle. Then, in order to take into account the interparticle correlation,
in particular the 'quantum backreaction' beyond the mean-field approximation,
we introduce the stochastic particle description for both the quantal and
semiquantal parts. A numerical application on a model of O2 scattering from a
Pt surface demonstrates that the proposed scheme gives correct asymptotic
behavior of the scattering probability, with improvement over the mixed
quantum-classical scheme with Bohmian particles, which is comprehended by
comparing the Bohmian and the stochastic trajectories.Comment: 4 pages, 2 figure
Imprints of galaxy evolution on H ii regions Memory of the past
  uncovered by the CALIFA survey

H ii regions in galaxies are the sites of star formation and thus particular
places to understand the build-up of stellar mass in the universe. The line
ratios of this ionized gas are frequently used to characterize the ionization
conditions. We use the Hii regions catalogue from the CALIFA survey (~5000 H ii
regions), to explore their distribution across the classical [OIII]/Hbeta vs.
[NII]/Halpha diagnostic diagram, and how it depends on the oxygen abundance,
ionization parameter, electron density, and dust attenuation. We compared the
line ratios with predictions from photoionization models. Finally, we explore
the dependences on the properties of the host galaxies, the location within
those galaxies and the properties of the underlying stellar population. We
found that the location within the BPT diagrams is not totally predicted by
photoionization models. Indeed, it depends on the properties of the host
galaxies, their galactocentric distances and the properties of the underlying
stellar population. These results indicate that although H ii regions are short
lived events, they are affected by the total underlying stellar population. One
may say that H ii regions keep a memory of the stellar evolution and chemical
enrichment that have left an imprint on the both the ionizing stellar
population and the ionized gasComment: 18 pages, 8 figures, accepted for publishing in A&
Self-Dual Supergravity in Seven Dimensions with Reduced Holonomy G_2

We present self-dual N=2 supergravity in superspace for Euclidean seven
dimensions with the reduced holonomy G_2 \subset SO(7), including all
higher-order terms. As its foundation, we first establish N=2 supergravity
without self-duality in Euclidean seven dimensions. We next show how the
generalized self-duality in terms of octonion structure constants can be
consistently imposed on the superspace constraints. We found two self-dual N=2
supergravity theories possible in 7D, depending on the representations of the
two spinor charges of N=2. The first formulation has both of the two spinor
charges in the {\bf 7} of G_2 with 24 + 24 on-shell degrees of freedom. The
second formulation has both charges in the {\bf 1} of G_2 with 16 + 16 on-shell
degrees of freedom.Comment: 14 pages, no figure
Gravity on a parallelizable manifold: Exact solutions

The wave type field equation $\square \vt^a=\la \vt^a$, where $\vt^a$ is a coframe field on a space-time, was recently proposed to describe the gravity field. This equation has a unique static, spherical-symmetric, asymptotically-flat solution, which leads to the viable Yilmaz-Rosen metric. We show that the wave type field equation is satisfied by the pseudo-conformal frame if the conformal factor is determined by a scalar 3D-harmonic function. This function can be related to the Newtonian potential of classical gravity. So we obtain a direct relation between the non-relativistic gravity and the relativistic model: every classical exact solution leads to a solution of the field equation. With this result we obtain a wide class of exact, static metrics. We show that the theory of Yilmaz relates to the pseudo-conformal sector of our construction. We derive also a unique cosmological (time dependent) solution of the described type
Branes from Unstable Systems of Branes

We discuss various aspects of the description of branes as topological solitons in unstable brane systems of higher dimensions. We first describe a classification of all the possible realisations of branes of M and type II theories as topological solitons of a brane-antibrane system. We then present a description of type IIB NS-NS p-branes in terms of topological solitons in systems of spacetime-filling NS9, anti-NS9 pairs and discuss the implications of these constructions in the description of BPS and non-BPS states in the strongly coupled Heterotic SO(32) theory. We finally present briefly the construction of a conjectured spacetime-filling non-BPS M10-brane, starting point for a brane descent construction of the branes of M-theory
Inclusive $D*^{+-}$ Production in Two-Photon Collisions at LEP

Inclusive D^{*+-} production in two-photon collisions is studied with the L3 detector at LEP, using 683 pb^{-1} of data collected at centre-of-mass energies from 183 to 208 GeV. Differential cross sections are determined as functions of the transverse momentum and pseudorapidity of the D^{*+-} mesons in the kinematic region 1 GeV < P_T < 12 GeV and |eta| < 1.4. The cross sections sigma(e^+e^- ---> e^+e^-D^{*+-}X)$ in this kinematical region is measured and the sigma(e^+e^- ---> e^+e^- cc{bar}X) cross section is derived. The measurements are compared with next-to-leading order perturbative QCD calculations.Inclusive D^{*+-} production in two-photon collisions is studied with the L3 detector at LEP, using 683 pb^{-1} of data collected at centre-of-mass energies from 183 to 208 GeV.

Duality Transformations in Supersymmetric Yang-Mills Theories coupled to
  Supergravity,

We consider duality transformations in N=2, d=4 Yang--Mills theory coupled to
N=2 supergravity. A symplectic and coordinate covariant framework is
established, which allows one to discuss stringy `classical and quantum duality
symmetries' (monodromies), incorporating T and S dualities. In particular, we
shall be able to study theories (like N=2 heterotic strings) which are
formulated in symplectic basis where a `holomorphic prepotential' F does not
exist, and yet give general expressions for all relevant physical quantities.
Duality transformations and symmetries for the N=1 matter coupled Yang--Mills
supergravity system are also exhibited. The implications of duality symmetry on
all N>2 extended supergravities are briefly mentioned. We finally give the
general form of the central charge and the N=2 semiclassical spectrum of the
dyonic BPS saturated states (as it comes by truncation of the N=4 spectrum).Comment: 41 pages, harvmac, no figures. References added, and minor printing

Unraveling the pattern of the $XYZ$ mesons

We present a plausible mechanism for the origin of the $XYZ$ mesons in the
heavy meson spectra within a standard quark-model picture. We discuss the
conditions required for the existence of four--quark bound states or resonances
contributing to the heavy meson spectra, being either compact or molecular. We
concentrate on charmonium and bottomonium spectra, where several new states,
difficult to understand as simple quark-antiquark pairs, have been reported by
different experimental collaborations. The pivotal role played by entangled
meson-meson thresholds is emphasized.Comment: 8 pages, 2 figure
When what we get is not what we want - The role of implemented versus desired merger patterns in support for mergers and perceived fairness

By integrating an intergroup perspective on mergers with discrepancy theories, we argue that merger partners aim for merger patterns that best benefit their group’s standing. Importantly, we hypothesize and show that the discrepancy between what merger partners want and what they actually get affects outcomes essential to merger success. Specifically, we demonstrate that perceived fit between the implemented and the desired merger pattern predicts support for the merger. We further show that this effect is mediated by perceived fairness (Study 1) and emotional reactions to the merger (Study 2). Our findings are generalized across a field study that investigate a real merger between two institutions of higher education (Study 1) and an experiment (Study 2).

A mathematical analysis of rebound in a target-mediated drug disposition model: I.Without feedback

We consider the possibility of free receptor (antigen/cytokine) levels rebounding to higher than the baseline level after one or more applications of an antibody drug using a target-mediated drug disposition model. Using geometry and dynamical systems analysis, we show that rebound will occur if and only if the elimination rate of the drug-receptor product is slower than the elimination rates of the drug and of the receptor. We also analyse the magnitude of rebound through approximations and simulations and demonstrate that it increases if the drug dose increases or if the difference between the elimination rate of the drug-receptor product and the minimum of the elimination rates of the drug and of the receptor increases. © 2013 Springer-Verlag Berlin Heidelberg
Evolution of the dust emission of massive galaxies up to z = 4 and constraints on their dominant mode of star formation

We aim to measure the average dust and molecular gas content of massive star-forming galaxies (>3 × 1010M⊙) up to z = 4 in the COSMOS field to determine if the intense star formation observed at high redshift is induced by major mergers or is caused by large gas reservoirs. Firstly, we measured the evolution of the average spectral energy distributions as a function of redshift using a stacking analysis of Spitzer, Herschel, LABOCA, and AzTEC data for two samples of galaxies: normal star-forming objects and strong starbursts, as defined by their distance to the main sequence. We found that the mean intensity of the radiation field ⟨ U ⟩ heating the dust (strongly correlated with dust temperature) increases with increasing redshift up to z = 4 in main-sequence galaxies. We can reproduce this evolution with simple models that account for the decrease in the gas metallicity with redshift. No evolution of ⟨ U ⟩ with redshift is found in strong starbursts. We then deduced the evolution of the molecular gas fraction (defined here as Mmol/ (Mmol + M⋆)) with redshift and found a similar, steeply increasing trend for both samples. At z ~ 4, this fraction reaches ~60%. The average position of the main-sequence galaxies is on the locus of the local, normal star-forming disks in the integrated Schmidt-Kennicutt diagram (star formation rate versus mass of molecular gas), suggesting that the bulk of the star formation up to z = 4 is dominated by secular processes
Rapid adherence to collagen IV enriches for tumour initiating cells in oral cancer.

<p>Background: Although several approaches for identification and isolation of carcinoma cells with tumour initiating properties have been established, enrichment of a population of pure and viable tumour-initiating cells (TICs) is still problematic. This study investigated possibilities to isolate a population of cancer cells with tumour initiating properties based on their adherence properties, rather than expression of defined markers or clonogenicity.</p>
<p>Methods: Several human cell lines derived from oral dysplasia and oral squamous cell carcinoma (OSCC), as well as primary cells derived from patients with OSCC were allowed to adhere to collagen IV-coated dishes sequentially. Rapid adherent cells (RAC), middle adherent cells (MAC) and late adherent cells (LAC) were then harvested and further investigated for their morphology, stem cell-like properties and molecular profile while grown in vitro and tongue xenotransplantation in NOD-SCID mice at serial dilutions.</p>
<p>Results: RAC showed significantly higher colony forming efficiency (p &lt; 0.05), sphere forming ability, greater migration ability (p &lt; 0.05), exhibited longer G2 phase and displayed higher expression of integrin b1 and other stem-cell related molecules as compared to MAC and LAC. RAC induced tongue tumours in NOD-SCID mice with the highest incidence. These tumours were also bigger and metastasised more frequently in loco-regional lymph nodes than MAC and LAC.</p>
<p>Conclusions: These findings prove for the first time that OSCC cells with tumour initiating properties can be enriched based on their rapid adhesiveness to collagen IV. This separation procedure provides a potentially useful tool for isolating TICs in OSCC for further studies on understanding their characteristics and drug-resistant behaviour.</p
Shards: a global view of the star formation activity at z ~ 0.84 and z ~ 1.23

In this paper, we present a comprehensive analysis of star-forming galaxies (SFGs) at intermediate redshifts (z ~ 1). We combine the ultra-deep optical spectro-photometric data from the Survey for High-z Absorption Red and Dead Sources (SHARDS) with deep UV-to-FIR observations in the GOODS-N field. Exploiting two of the 25 SHARDS medium-band filters, F687W17 and F823W17, we select [O II] emission line galaxies at z ~ 0.84 and z ~ 1.23 and characterize their physical properties. Their rest-frame equivalent widths (EWrf([O ii])), line fluxes, luminosities, star formation rates (SFRs), and dust attenuation properties are investigated. The evolution of EW_rf([O II]) closely follows the SFR density evolution of the universe, with a trend of EW_rf([O II]) ∞ (1 + z)^3 up to redshift z ≃1, followed by a possible flattening. The SF properties of the galaxies selected on the basis of their [O II] emission are compared with complementary samples of SFGs selected by their MIR and FIR emission, and also with a general mass-selected sample of galaxies at the same redshifts. We demonstrate observationally that the UVJ diagram (or, similarly, a cut in the specific SFR) is only partially able to distinguish the quiescent galaxies from the SFGs. The SFR–M_* relation is investigated for the different samples, yielding a logarithmic slope ~1, in good agreement with previous results. The dust attenuations derived from different SFR indicators (UV(1600), UV(2800), [O II], IR) are compared and show clear trends with respect to both the stellar mass and total SFR, with more massive and highly star-forming galaxies being affected by stronger dust attenuation
Low post-glacial rebound rates in the Weddell Sea due to Late Holocene ice-sheet re-advance

Many ice-sheet reconstructions assume monotonic Holocene retreat for the West Antarctic Ice Sheet, but an increasing number of glaciological observations infer that some portions of the ice sheet may be readvancing, following retreat behind the present-day margin. A readvance in the Weddell Sea region can reconcile two outstanding problems: (i) the present-day widespread occurrence of seemingly stable ice streams grounded on beds that deepen inland; and (ii) the inability of models of glacial isostatic adjustment to match present-day uplift rates. By combining a suite of ice loading histories that include a readvance with a model of glacial isostatic adjustment we report substantial improvements to predictions of present-day uplift rates, including reconciling one problematic observation of land sinking. We suggest retreat behind present grounding lines occurred when the bed was lower, and isostatic recovery has since led to shallowing, ice sheet re-grounding and readvance. The paradoxical existence of grounding lines in apparently unstable configurations on reverse bed slopes may be resolved by invoking the process of unstable advance, in accordance with our load modelling
Management based on exhaled nitric oxidelevels adjusted for atopy reduces asthma exacerbations in children : A dual centre randomised controlled trial

While several randomised control trials (RCTs) have evaluated the use of fractional exhaled nitric oxide (FeNO) to improve asthma outcomes, none used FeNO cut-offs adjusted for atopy, a determinant of FeNO levels. In a dual centre RCT, we assessed whether a treatment strategy based on FeNO levels, adjusted for atopy, reduces asthma exacerbations compared with the symptoms-based management (controls).\ud
\ud
Children with asthma from hospital clinics of two hospitals were randomly allocated to receive an a-priori determined treatment hierarchy based on symptoms or FeNO levels. There was a 2-week run-in period and they were then reviewed ten times over 12-months. The primary outcome was the number of children with exacerbations over 12-months. \ud
\ud
Sixty-three children were randomised (FeNO=31, controls=32); 55 (86%) completed the study. Although we did achieve our planned sample size, significantly fewer children in the FeNO group (6 of 27) had an asthma exacerbation compared to controls (15 of 28), p=0.021; number to treat for benefit=4 (95%CI 3-24). There was no difference between groups for any secondary outcomes (quality of life, symptoms, FEV1). The final daily inhaled corticosteroids (ICS) dose was significantly (p=0.037) higher in the FeNO group (median 400µg, IQR 250-600) compared to the controls (200, IQR100-400). \ud
\ud
Taking atopy into account when using FeNO to tailor asthma medications is likely beneficial in reducing the number of children with severe exacerbations at the expense of increased ICS use. However, the strategy is unlikely beneficial for improving asthma control. A larger study is required to confirm or refute our findings
Production of the 1S0 diproton in the pp->pp pi0 reaction at 0.8 GeV

The pp -> pp pi(0) differential cross section has been measured with the ANKE spectrometer at COSY-Julich for pion cms angles between 0 degrees and 15.4 degrees at a proton beam energy of 0.8 GeV. The selection of diproton pairs with an excitation energy E-pp < 3 MeV ensures that the final pp system is dominantly in the spin-singlet S-1(0) state. The kinematics are therefore very similar to those of pp -> d pi(+) but with different spin and isospin transitions. The cross sections are over two orders of magnitude smaller than those of pp -> d pi(+) and show a forward dip that is even stronger than that seen at lower energies. The results should provide a crucial extra test of pion production models in nucleon-nucleon collisions. (c) 2006 Elsevier B.V. All rights reserved
Isospin-breaking corrections in the pion--deuteron scattering length

It is shown that isospin-breaking corrections to the pion-deuteron scattering length can be very large, because of the vanishing of the isospin-symmetric contribution to this scattering length at leading order in chiral perturbation theory. We further demonstrate that these corrections can explain the bulk of the discrepancy between the recent experimental data on pionic hydrogen and picnic deuterium. We also give the first determination of the electromagnetic low-energy constant f(1). (c) 2006 Elsevier B.V. All rights reserved
