SO(3) Monopoles, Level-One Seiberg-Witten Moduli Spaces, and Witten's
  Conjecture in Low Degrees

We prove Witten's formula relating the Donaldson and Seiberg-Witten series
modulo powers of degree $c+2$, with $c=-{1/4}(7\chi+11\sigma)$, for
four-manifolds obeying some mild conditions, where $\chi$ and $\sigma$ are
their Euler characteristic and signature. We use the moduli space of SO(3)
monopoles as a cobordism between a link of the Donaldson moduli space of
anti-self-dual SO(3) connections and links of the moduli spaces of
Seiberg-Witten monopoles. Gluing techniques allow us to compute contributions
from Seiberg-Witten moduli spaces lying in the first (or `one-bubble') level of
the Uhlenbeck compactification of the moduli space of SO(3) monopoles.Comment: Minor corrections; details added. Topology and its Applications, 91

Electromagnetic Radiation from Hot and Dense Hadronic Matter

The modifications of hadronic masses and decay widths at finite temperature
and baryon density are investigated using a phenomenological model of hadronic
interactions in the Relativistic Hartree Approximation. We consider an
exhaustive set of hadronic reactions and vector meson decays to estimate the
photon emission from hot and dense hadronic matter. The reduction in the vector
meson masses and decay widths is seen to cause an enhancement in the photon
production. It is observed that the effect of $\rho$-decay width on photon
spectra is negligible. The effects on dilepton production from pion
annihilation are also indicated.Comment: To appear in Nucl. Phys.
Commentary on the WHO Classification of Tumors of Lymphoid Tissues (2008): “Gray Zone” Lymphomas Overlapping with Burkitt Lymphoma or Classical Hodgkin Lymphoma

The 2008 WHO Classification of Tumors of Haematopoietic and Lymphoid Tissues has introduced two new categories of high-grade B-cell lymphomas: entities in which features of diffuse large B-cell lymphoma (DLBCL) overlap with Burkitt lymphoma (DLBCL/BL) or classical Hodgkin lymphoma (DLBCL/HL). The DLBCL/BL category encompasses cases that resemble Burkitt lymphoma morphologically, but have one or more immunophenotypic or molecular genetic deviations that would exclude it from the BL category; conversely, some cases have immunophenotypic and/or genetic features of BL, but display cytologic variability unacceptable for BL. Many of the cases in the DLBCL/BL category contain a translocation of MYC as well as either BCL2 or BCL6 (so-called double-hit lymphomas) and have a very aggressive clinical behavior. The DLBCL/HL category encompasses lymphomas that exhibit the morphology of classical Hodgkin lymphoma but the immunophenotype of DLBCL, or vice versa. Most DLBCL/HL cases described present as mediastinal masses, but this category is not limited to mediastinal lymphomas. These new categories acknowledge the increasing recognition of cases that display mixed features of two well-established diseases. Whether the existence of such cases reflects shortcomings of our current diagnostic armamentarium or a true disease continuum in which such hybrid or intermediate neoplasms actually exist remains to be determined
A Dirac-Dunkl equation on $S^2$ and the Bannai-Ito algebra

The Dirac-Dunkl operator on the 2-sphere associated to the $\mathbb{Z}_2^3$
reflection group is considered. Its symmetries are found and are shown to
generate the Bannai-Ito algebra. Representations of the Bannai-Ito algebra are
constructed using ladder operators. Eigenfunctions of the spherical Dirac-Dunkl
operator are obtained using a Cauchy-Kovalevskaia extension theorem. These
eigenfunctions, which correspond to Dunkl monogenics, are seen to support
finite-dimensional irreducible representations of the Bannai-Ito algebra.Comment: 17 pages, 1 diagra
Magnetothermoelectric Response from Holography

In this note we study the effects of a magnetic field on transport using
holographic models with broken translational invariance. We show that, after
carefully subtracting off non-trivial magnetisation currents, it is possible to
express the DC transport currents of the boundary theory in terms of properties
of a black hole horizon. This allows us to obtain simple analytic expressions
for the electrical, thermoelectric and heat conductivity tensors. Our results
apply to both isotropic and anisotropic models, including holographic
Q-lattices and to certain theories where translational invariance is broken by
linear sources for axions.Comment: 12 pages + appendices, v2: version published in JHE
Differential top-antitop cross-section measurements as a function of
  observables constructed from final-state particles using pp collisions at
  $\sqrt{s}=7$ TeV in the ATLAS detector

Various differential cross-sections are measured in top-quark pair
($t\bar{t}$) events produced in proton-proton collisions at a centre-of-mass
energy of $\sqrt{s} = 7$ TeV at the LHC with the ATLAS detector. These
differential cross-sections are presented in a data set corresponding to an
integrated luminosity of $4.6$ fb$^{-1}$. The differential cross-sections are
presented in terms of kinematic variables, such as momentum, rapidity and
invariant mass, of a top-quark proxyreferred to as the pseudo-top-quark as well
as the pseudo-top-quark pair system. The dependence of the measurement on
theoretical models is minimal.
  The measurements are performed on $t\bar{t}$ events in the lepton+jets
channel, requiring exactly one charged lepton and at least four jets with at
least two of them tagged as originating from a $b$-quark. The hadronic and
leptonic pseudo-top-quarks are defined via the leptonic or hadronic decay mode
of the $W$ boson produced by the top-quark decay in events with a single
charged lepton. Differential cross-section measurements of the pseudo-top-quark
variables are compared with several Monte Carlo models that implement
next-to-leading order or leading-order multi-leg matrix-element calculations.Comment: Published version, 43 pages plus author list + cover pages (65 pages

Poisson Lie symmetry and D-branes in WZW model on the Heisenberg Lie
  group $H_4$

We show that the WZW model on the Heisenberg Lie group $H_4$ has Poisson-Lie
symmetry only when the dual Lie group is ${ A}_2 \oplus 2{ A}_1$. In this way,
we construct the mutual T-dual sigma models on Drinfel'd double generated by
the Heisenberg Lie group $H_4$ and its dual pair, ${ A}_2 \oplus 2{ A}_1$, as
the target space in such a way that the original model is the same as the $H_4$
WZW model. Furthermore, we show that the dual model is conformal up to two
loops order. Finally, we discuss $D$-branes and the worldsheet boundary
conditions defined by a gluing matrix on the $H_4$ WZW model. Using the duality
map obtained from the canonical transformation description of the Poisson-Lie
T-duality transformations for the gluing matrix which locally defines the
properties of the $D$-brane, we find two different cases of the gluing matrices
for the WZW model based on the Heisenberg Lie group $H_4$ and its dual model.Comment: 17 page
On-shell Diagrams, Gra{\ss}mannians and Integrability for Form Factors

We apply on-shell and integrability methods that have been developed in the
context of scattering amplitudes in N=4 SYM theory to tree-level form factors
of this theory. Focussing on the colour-ordered super form factors of the
chiral part of the stress-tensor multiplet as an example, we show how to
systematically construct on-shell diagrams for these form factors with the
minimal form factor as further building block in addition to the three-point
amplitudes. Moreover, we obtain analytic representations in terms of
Gra{\ss}mannian integrals in spinor helicity, twistor and momentum twistor
variables. While Yangian invariance is broken by the operator insertion, we
find that the form factors are eigenstates of the integrable spin-chain
transfer matrix built from the monodromy matrix that yields the Yangian
generators. Constructing them via the method of R operators allows to introduce
deformations that preserve the integrable structure. We finally show that the
integrable properties extend to minimal tree-level form factors of generic
composite operators as well as certain leading singularities of their n-point
loop-level form factors.Comment: 44 pages, several figures; v2: References added, typos corrected,

Resonant Absorption of Transverse Oscillations and Associated Heating in
  a Solar Prominence. I- Observational aspects

Transverse magnetohydrodynamic (MHD) waves have been shown to be ubiquitous
in the solar atmosphere and can in principle carry sufficient energy to
generate and maintain the Sun's million-degree outer atmosphere or corona.
However, direct evidence of the dissipation process of these waves and
subsequent heating has not yet been directly observed. Here we report on high
spatial, temporal, and spectral resolution observations of a solar prominence
that show a compelling signature of so-called resonant absorption, a long
hypothesized mechanism to efficiently convert and dissipate transverse wave
energy into heat. Aside from coherence in the transverse direction, our
observations show telltale phase differences around 180 degrees between
transverse motions in the plane-of-sky and line-of-sight velocities of the
oscillating fine structures or threads, and also suggest significant heating
from chromospheric to higher temperatures. Comparison with advanced numerical
simulations support a scenario in which transverse oscillations trigger a
Kelvin-Helmholtz instability (KHI) at the boundaries of oscillating threads via
resonant absorption. This instability leads to numerous thin current sheets in
which wave energy is dissipated and plasma is heated. Our results provide
direct evidence for wave-related heating in action, one of the candidate
coronal heating mechanisms.Comment: 28 pages, 9 figures, accepted for publication in ApJ. Part II by

Mass Spectra of $0^{+-}$, $1^{-+}$, and $2^{+-}$ Exotic Glueballs

With appropriate interpolating currents the mass spectra of $0^{+-}$,
$1^{-+}$, and $2^{+-}$ oddballs are studied in the framework of QCD sum rules
(QCDSR). We find there exits one stable $0^{+-}$ oddball with mass of $4.57 \pm
0.13 \, \text{GeV}$, and one stable $2^{+-}$ oddball with mass of $6.06 \pm
0.13 \, \text{GeV}$, whereas, no stable $1^{-+}$ oddball shows up. The possible
production and decay modes of these glueballs with unconventional quantum
numbers are analyzed, which are hopefully measurable in either BELLEII, PANDA,
Super-B or LHCb experiments.Comment: 10 pages, 12 figures, 4 tables, to appear in NPB. arXiv admin note:

Response of seagrass indicators to shifts in environmental stressors: A global review and management synthesis

Although seagrass-based indicators are widely used to assess coastal ecosystem status, there is little universality in their application. Matching the plethora of available indicators to specific management objectives requires a detailed knowledge of their species-specific sensitivities and their response time
to environmental stressors. We conducted an extensive survey of experimental studies to determine the sensitivity and response time of seagrass indicators to ecosystem degradation and recovery. We identified seagrass size and indicator type (i.e. level of biological organization of the measure) as the main factors affecting indicator sensitivity and response time to degradation and recovery. While structural and demographic parameters (e.g. shoot density, biomass) show a high and unspecific sensitivity, biochemical/physiological indicators present more stressor-specific responses and are the most sensitive detecting early phases of environmental improvement. Based on these results we present a simple decision tree to assist ecosystem managers to match adequate and reliable indicators to specific management goals
Measurement of the charge asymmetry in dileptonic decays of top quark pairs in pp collisions at √s = 7 TeV using the ATLAS detector

A measurement of the top-antitop (tt¯) charge asymmetry is presented using data corresponding to an integrated luminosity of 4.6 fb−1 of LHC pp collisions at a centreof-mass energy of 7 TeV collected by the ATLAS detector. Events with two charged leptons, at least two jets and large missing transverse momentum are selected. Two observables are studied: A C ℓℓ based on the identified charged leptons, and Att¯C, based on the reconstructed tt final state. The asymmetries are measured to be
AℓℓC=0.024±0.015(stat.)±0.009(syst.),
Att¯C=0.021±0.025(stat.)±0.017(syst.).
The measured values are in agreement with the Standard Model predictions
International Conference on Greenhouse Gas Technologies (GHGT-12) Models for CO2 injection with coupled thermal proce

Large-scale models of carbon dioxide (CO2) storage in geological formations must capture the relevant physical, chemical and thermodynamic processes that affect the migration and ultimate fate of injected CO2. These processes should be modeled over the appropriate length and time scales. Some important mechanisms include convection- driven dissolution, caprock roughness, and local capillary effects, all of which can impact the direction and speed of the plume as well as long-term trapping efficiency. In addition, CO2 can be injected at a different temperature than reservoir conditions, leading to significant density variation within the plume over space and time. This impacts buoyancy and migration patterns, which becomes particularly important for injection sites with temperature and pressure conditions near the critical point. Therefore, coupling thermal processes with fluid flow should be considered in order to correctly capture plume migration and trapping within the reservoir. This study focuses on compositional non- isothermal flow using 3D and vertically upscaled models. The model concept is demonstrated on simple systems. In addition, we explore CO2 thermodynamic models for reliable prediction of density under different injection pressures, temperatures and composition
Star formation in the local Universe from the CALIFA sample. I. Calibrating the SFR using IFS data

Context. The star formation rate (SFR) is one of the main parameters used to analyze the evolution of galaxies through time. The need for recovering the light reprocessed by dust commonly requires the use of low spatial resolution far-infrared data. Recombination line luminosities provide an alternative, although uncertain dust-extinction corrections based on narrowband imaging or long-slit spectroscopy have traditionally posed a limit to their applicability. Integral field spectroscopy (IFS) is clearly the way to overcome this kind of limitation.\ud
Aims. We obtain integrated Hα, ultraviolet (UV) and infrared (IR)-based SFR measurements for 272 galaxies from the CALIFA survey at 0.005 <z< 0.03 using single-band and hybrid tracers. We aim to determine whether the extinction-corrected Hα luminosities provide a good measure of the SFR and to shed light on the origin of the discrepancies between tracers. Updated calibrations referred to Hα are provided. The well-defined selection criteria and large statistics allow us to carry out this analysis globally and split by properties, including stellar mass and morphological type.\ud
Methods. We derive integrated, extinction-corrected Hα fluxes from CALIFA, UV surface and asymptotic photometry from GALEX and integrated WISE 22 μm and IRAS fluxes.\ud
Results. We find that the extinction-corrected Hα luminosity agrees with the hybrid updated SFR estimators based on either UV or Hα plus IR luminosity over the full range of SFRs (0.03−20 M_⊙ yr^-1). The coefficient that weights the amount of energy produced by newly-born stars that is reprocessed by dust on the hybrid tracers, a_IR, shows a large dispersion. However, this coefficient does not became increasingly small at high attenuations, as expected if significant highly-obscured Hα emission were missed, i.e., after a Balmer decrement-based attenuation correction is applied. Lenticulars, early-type spirals, and type-2 AGN host galaxies show smaller coefficients because of the contribution of optical photons and AGN to dust heating.\ud
Conclusions. In the local Universe, the Hα luminosity derived from IFS observations can be used to measure SFR, at least in statistically-significant, optically-selected galaxy samples, once stellar continuum absorption and dust attenuation effects are accounted for. The analysis of the SFR calibrations by galaxies properties could potentially be used by other works to study the impact of different selection criteria in the SFR values derived, and to disentangle selection effects from other physically motivated differences, such as environmental or evolutionary effects
The GEOTRACES Intermediate Data Product 2014

The GEOTRACES Intermediate Data Product 2014 (IDP2014) is the first publicly available data product of the international GEOTRACES programme, and contains data measured and quality controlled before the end of 2013. It consists of two parts: (1) a compilation of digital data for more than 200 trace elements and isotopes (TEIs) as well as classical hydrographic parameters, and (2) the eGEOTRACES Electronic Atlas providing a strongly inter-linked on-line atlas including more than 300 section plots and 90 animated 3D scenes. The IDP2014 covers the Atlantic, Arctic, and Indian oceans, exhibiting highest data density in the Atlantic. The TEI data in the IDP2014 are quality controlled by careful assessment of intercalibration results and multi-laboratory data comparisons at cross-over stations. The digital data are provided in several formats, including ASCII spreadsheet, Excel spreadsheet, netCDF, and Ocean Data View collection. In addition to the actual data values the IDP2014 also contains data quality flags and 1-σ data error values where available. Quality flags and error values are useful for data filtering. Metadata about data originators, analytical methods and original publications related to the data are linked to the data in an easily accessible way. The eGEOTRACES Electronic Atlas is the visual representation of the IDP2014 data providing section plots and a new kind of animated 3D scenes. The basin-wide 3D scenes allow for viewing of data from many cruises at the same time, thereby providing quick overviews of large-scale tracer distributions. In addition, the 3D scenes provide geographical and bathymetric context that is crucial for the interpretation and assessment of observed tracer plumes, as well as for making inferences about controlling processes
Theory of mind and the brain in anorexia nervosa: relation to treatment outcome.

Converging evidence suggests deficits in theory-of-mind (ToM) processing in patients with anorexia nervosa (AN). The present study aimed at elucidating the neural mechanisms underlying ToM-deficits in AN.A total of 19 adolescent patients with AN and 21 age-matched controls were investigated using functional magnetic resonance imaging during performance of a ToM-task at two time points (in-patients: admission to hospital and discharge after weight recovery). Clinical outcomes in patients were determined 1 year after admission.Irrespective of the time point, AN patients showed reduced activation in middle and anterior temporal cortex and in the medial prefrontal cortex. Hypoactivation in the medial prefrontal cortex at admission to hospital (T1) was correlated with clinical outcome at follow-up.Hypoactivation in the brain network supporting theory of mind may be associated with a social-cognitive endophenotype reflecting impairments of social functioning in anorexia nervosa which is predictive for a poor outcome at 1-year follow-up
3-cocycles, non-associative star-products and the magnetic paradigm of R -flux string vacua

We consider the geometric and non-geometric faces of closed string vacua arising by T-duality from principal torus bundles with constant H -flux and pay attention to their double phase space description encompassing all toroidal coordinates, momenta and their dual on equal footing. We construct a star-product algebra on functions in phase space that is manifestly duality invariant and substitutes for canonical quantization. The 3-cocycles of the Abelian group of translations in double phase space are seen to account for non-associativity of the star-product. We also provide alternative cohomological descriptions of non-associativity and draw analogies with the quantization of point-particles in the field of a Dirac monopole or other distributions of magnetic charge. The magnetic field analogue of the R -flux string model is provided by a constant uniform distribution of magnetic charge in space and non-associativity manifests as breaking of angular symmetry. The Poincaré vector comes to rescue angular symmetry as well as associativity and also allow for quantization in terms of operators and Hilbert space only in the case of charged particles moving in the field of a single magnetic monopole
Improved Epstein–Glaser renormalization in x -space versus differential renormalization

Renormalization of massless Feynman amplitudes in x -space is reexamined here, using almost exclusively real-variable methods. We compute a wealth of concrete examples by means of recursive extension of distributions. This allows us to show perturbative expansions for the four-point and two-point functions at several loop order. To deal with internal vertices, we expound and expand on convolution theory for log-homogeneous distributions. The approach has much in common with differential renormalization as given by Freedman, Johnson and Latorre; but differs in important details
Excitation of giant monopole resonance in 208 Pb and 116 Sn using inelastic deuteron scattering

The excitation of the isoscalar giant monopole resonance (ISGMR) in 208 Pb and 116 Sn has been investigated using small-angle (including 0°) inelastic scattering of 100 MeV/u deuteron and multipole-decomposition analysis (MDA). The extracted strength distributions agree well with those from inelastic scattering of 100 MeV/u α particles. These measurements establish deuteron inelastic scattering at <math altimg="si1.gif" xmlns="http://www.w3.org/1998/Math/MathML"><msub><mrow><mi>E</mi></mrow><mrow><mi>d</mi></mrow></msub><mo>∼</mo><mn>100</mn><mtext> </mtext><mtext>MeV</mtext><mo stretchy="false">/</mo><mtext>u</mtext></math> as a suitable probe for extraction of the ISGMR strength with MDA, making feasible the investigation of this resonance in radioactive isotopes in inverse kinematics
Excitation energy dependence of fragment-mass distributions from fission of 180,190 Hg formed in fusion reactions of 36 Ar + 144,154 Sm

Mass distributions of fission fragments from the compound nuclei 180 Hg and 190 Hg formed in fusion reactions 36 Ar + 144 Sm and 36 Ar + 154 Sm, respectively, were measured at initial excitation energies of E⁎(Hg180)=33–66 MeV and E⁎(Hg190)=48–71 MeV . In the fission of 180 Hg, the mass spectra were well reproduced by assuming only an asymmetric-mass division, with most probable light and heavy fragment masses A¯L/A¯H=79/101 . The mass asymmetry for 180 Hg agrees well with that obtained in the low-energy β+/EC -delayed fission of 180 Tl, from our earlier ISOLDE(CERN) experiment. Fission of 190 Hg is found to proceed in a similar way, delivering the mass asymmetry of A¯L/A¯H=83/107 , throughout the measured excitation energy range. The persistence as a function of excitation energy of the mass-asymmetric fission for both proton-rich Hg isotopes gives strong evidence for the survival of microscopic effects up to effective excitation energies of compound nuclei as high as 40 MeV. This behavior is different from fission of actinide nuclei and heavier mercury isotope 198 Hg
