Analytical expressions for the deprojected Sérsic model

The Sersic model has become the standard for parametrizing the surface brightness distribution of early-type galaxies and bulges of spiral galaxies. A major problem is that the deprojection of the Sersic surface brightness profile to a luminosity density cannot be executed analytically for general values of the Sersic index. We use Mellin integral transforms to derive an analytical expressions for the luminosity density in terms of the Fox H function for all values of the Sersic index. We derive simplified expressions for the luminosity density, cumulative luminosity, and gravitational potential in terms of the Meijer G function for all rational values of the Sersic index, and we investigate their asymptotic behaviour at small and large radii. As implementations of the Meijer G function are currently available both in symbolic computer algebra packages and as high-performance computing code, our results open up the possibility to calculate the density of the Sersic models to arbitrary precision
Search for exotic resonances decaying into WZ/ZZ in pp collisions at √s=7 TeV

Journal of High Energy Physics 2013.2 (2013): 036 reproduced by permission of Scuola Internazionale Superiore di Studi Avanzati (SISSA)Artículo escrito por un elevado número de autores, solo se referencian el que aparece en primer lugar, el nombre del grupo de colaboración, si le hubiere, y los autores pertenecientes a la UAMA search for new exotic particles decaying to the VZ final state is performed, where V is either a W or a Z boson decaying into two overlapping jets and the Z decays into a pair of electrons, muons or neutrinos. The analysis uses a data sample of pp collisions corresponding to an integrated luminosity of 5 fb-1 collected by the CMS experiment at the LHC at √s=7 TeV in 2011. No significant excess is observed in the mass distribution of the VZ candidates compared with the background expectation from standard model processes. Model-dependent upper limits at the 95% confidence level are set on the product of the cross section times the branching fraction of hypothetical particles decaying to the VZ final state as a function of mass. Sequential standard model W′ bosons with masses between 700 and 940 GeV are excluded. In the Randall-Sundrum model for graviton resonances with a coupling parameter of 0.05, masses between 750 and 880 GeV are also exclude
Meson resonances at large N(C): Complex poles vs Breit-Wigner masses

The rigorous quantum mechanical definition of a resonance requires determining the pole position in the second Riemann sheet of the analytically continued partial wave scattering amplitude in the complex Mandelstam s variable plane. For meson resonances we investigate the alternative Breit-Wigner (BW) definition within the large N-C expansion. By assuming that the pole position is O(N-C(0)) and exploiting unitarity, we show that the BW determination of the resonance mass differs from the pole position by O(N-C(-2)) terms, which can be extracted from pi pi scattering data. For the case of the a (f(0)(600)) pole, the BW scalar mass is predicted to occur at similar to 700 MeV while the true value is located at similar to 800 MeV
Status of the MSW solutions of the solar neutrino problem

We present an updated global analysis of two-flavour MSW solutions to the solar neutrino problem. We perform a fit to the full data set corresponding to the 825-day Super-Kamiokande data sample as well as to chlorine, GALLEX and SAGE experiments. In our analysis we use all measured total event rates as well as all Super-Kamiokande data on the zenith angle dependence, energy spectrum and seasonal variation of the events. We compare the quality of the solutions of the solar neutrino anomaly in terms of conversions of v(e) into active or sterile neutrinos. For the case of conversions into active neutrinos we find that, although the data on the total event rates favours the Small Mixing Angle (SMA) solution, once the full data set is included both SMA and Large Mixing Angle (LMA) solutions give an equally good Fit to the data. We find that the best-fit points for the combined analysis are Delta m(2) = 3.6 X 10(-5) eV(2) and sin(2)2 theta = 0.79 with chi(min)(2) = 35.4/30 d.o.f. and Delta m(2) = 5.1 x 10(-6) eV(2) and sin(2)2 theta = 5.5 X 10(-3) with chi(min)(2) = 37.4/30 dof In contrast with the earlier 504-day study of Bahcall-Krastev-Smirnov our results indicate that the LMA solution is not only allowed, but slightly preferred. On the other hand, we show that seasonal effects, although small, may still leach 11% in the lower part of the LMA region, without conflict with the negative hints of a day-night variation (6% is due to the eccentricity of the Earth's orbit). In particular the best-fit LMA solution predicts a seasonal effect of 8.5%. For conversions into sterile neutrinos only the SMA solution is possible with best-fit point Delta m(2) = 5.0 X 10(-6) eV(2) and sin(2)2 theta = 3. X 10(-3) and chi(min)(2) = 40.2/30 d.o.f. We also consider departures of the Standard Solar Model (SSM) of Bahcall and Pinsonneault 1998 (BP98) by allowing arbitrary B-8 and hep fluxes. These modifications do not alter significantly the oscillation parameters. The best fit is obtained for B-8/B-8(SSM) = 0.61 and hep/hep(SSM) = 12 for the SMA solution both fur conversions into active or sterile neutrinos and B-8/B-8(SSM)=1.37 and hep/hep(SSM) = 38 for the LMA solution
Study of Mass Oxygen Transfer in a Biotrickling Filter for Air Pollution Control

Biotrickling filtration is a potential and cost effective alternative for the treatment of volatile organic compound\ud
(VOC) emissions in air, so it is necessary to deepen into the key aspects of design and operation for the optimization\ud
of this technology. One of these factors is the oxygen mass transfer of the process. This study would facilitate the\ud
selection of the packing material and the mathematical modelling and simulation of bioreactors. Four plastic packing\ud
materials with a different specific surface area have been evaluated in terms of oxygen mass transfer. For the tested\ud
range of superficial liquid velocities, data show a relationship between the kLa and the superficial liquid velocity in\ud
all packing materials used, except for the biggest plastic rings. No significant differences in mass transfer coefficients\ud
at low liquid velocities were observed, however dependency between oxygen transfer and specific surface area\ud
increased considerably for high liquid velocities. No significant influences of the superficial air velocity were\ud
observed
Exploring the critical dependence of adsorption of various dyes on the degradation rate using Ln3+-​TiO2 surface under UV​/solar light

The degrdn. of structurally different anionic dyes like Alizarin Red S (ARS) Amaranth (AR)​, Brilliant Yellow (BY)​, Congo Red (CR)​, Fast Red (FR)​, Methyl orange (MO)​, and Methyl red (MR) were carried out using Ln3+ (Ln3+ = La3+, Ce3+ and Gd3+) doped TiO2 at different pH conditions under UV​/solar light.  All the anionic dyes underwent rapid degrdn. at acidic pH, while resisted at alk. conditions due to the adsorptive tendency of these dyes on the catalyst surface at different pH conditions.  Gd3+ (0.15 mol​%)​-​TiO2 exhibited better activity compared to other photocatalyst ascribed to half filled electronic configuration of Gd3+ ions.  It is proposed that Ln3+ serves only as charge carrier traps under UV light, while it also act as visible light sensitizers under solar light.  Irresp. of the catalyst and excitation source, the dye degrdn. followed the order: AR > FR > MO > MR > ARS > BY > CR.  The results suggest that pre-​adsorption of the pollutant is vital for efficient photocatalysis which is dependent on the nature of the substituent's group attached to the dye mol
Enhanced photoluminescence of Gd2O3:Eu3+ nanophosphors with alkali (M = Li+, Na+, K+) metal ion co-​doping

Gd1.95Eu0.04M0.01O3 (M = Li+, Na+, K+) nanophosphors were synthesized by a low temp. soln. combustion (LSC) method.  Powder x-​ray diffraction pattern (PXRD)​, SEM, UV-​visible and photoluminescence (PL) measurements were carried out to characterize their structural and luminescent properties.  The excitation and emission spectra indicated that the phosphor could be well excited by UV light (243 nm) and emit red light ∼612 nm.  The effect of alkali co-​dopant on PL properties was examd.  Incorporation of Li+, Na+ and K+ in to Gd2O3:Eu3+ phosphor would lead to a remarkable increase of photoluminescence.  The PL intensity of Gd2O3:Eu3+ phosphor was improved evidently by co-​doping with Li+ ions whose radius is less than that of Gd3+ and hardly with Na+, K+ whose radius is larger than that of Gd3+.  The effect of co-​dopants on enhanced luminescence was mainly regarded as the result of a suitable local distortion of crystal field surrounding the Eu3+ activator.  These results will play an important role in seeking some more effective co-​dopants
Detecting functional decline from normal ageing to dementia: development
  and validation of a short version of the Amsterdam IADL Questionnaire

INTRODUCTION: Detecting functional decline from normal ageing to dementia is
relevant for diagnostic and prognostic purposes. Therefore, the Amsterdam IADL
Questionnaire (A-IADL-Q) was developed: a 70-item proxy-based tool with good
psychometric properties. We aimed to design a short version whilst preserving
its psychometric quality. METHODS: Study partners of subjects (n=1355), ranging
from cognitively normal to dementia subjects, completed the original A-IADL-Q.
We selected the short version items using a stepwise procedure combining
missing data, Item Response Theory and input from respondents and experts. We
investigated internal consistency of the short version as well as concordance
with the original version. To assess its construct validity, we additionally
investigated concordance between the short version and the Mini-Mental State
Examination (MMSE) and Disability Assessment for Dementia (DAD). Lastly, we
investigated differences in IADL scores between diagnostic groups across the
dementia spectrum. RESULTS: We selected 30 items covering the entire spectrum
of IADL functioning. Internal consistency (.98) and concordance with the
original version (.97) were very high. Concordance with the MMSE (.72) and DAD
(.87) scores was high. IADL impairment scores increased across the spectrum
from normal cognition to dementia. DISCUSSION: The A-IADL-Q Short Version
(A-IADL-Q-SV) consists of 30 items. The A-IADL-Q-SV has maintained the
psychometric quality of the original A-IADL-Q. As such, it is a concise measure
of functional decline.Comment: 14 pages, 3 tables, 4 figure
Search for quark contact interactions and extra spatial dimensions using dijet angular distributions in proton-proton collisions at √s = 8 TeV

A search is presented for quark contact interactions and extra spatial dimensions in proton-proton collisions at √s=8 TeV using dijet angular distributions. The search is based on a data set corresponding to an integrated luminosity of 19.7 fb-1 collected by the CMS detector at the CERN LHC. Dijet angular distributions are found to be in agreement with the perturbative QCD predictions that include electroweak corrections. Limits on the contact interaction scale from a variety of models at next-to-leading order in QCD corrections are obtained. A benchmark model in which only left-handed quarks participate is excluded up to a scale of 9.0 (11.7) TeV for destructive (constructive) interference at 95% confidence level. Lower limits between 5.9 and 8.4 TeV on the scale of virtual graviton exchange are extracted for the Arkani-Hamed-Dimopoulos-Dvali model of extra spatial dimensionsWe acknowledge the enduring support for the construction and operation of the LHC and the CMS detector provided by the following funding agencies: BMWFW and FWF (Austria); FNRS and FWO (Belgium); CNPq, CAPES, FAPERJ, and FAPESP (Brazil); MES (Bulgaria); CERN; CAS, MoST, and NSFC (China); COLCIENCIAS (Colombia); MSES and CSF (Croatia); RPF (Cyprus); MoER, ERC IUT and ERDF (Estonia); Academy of Finland, MEC, and HIP (Finland); CEA and CNRS/IN2P3 (France); BMBF, DFG, and HGF (Germany); GSRT (Greece); OTKA and NIH (Hungary); DAE and DST (India); IPM (Iran); SFI (Ireland); INFN (Italy); MSIP and NRF (Republic of Korea); LAS (Lithuania); MOE and UM (Malaysia); CINVESTAV, CONACYT, SEP, and UASLPFAI (Mexico); MBIE (New Zealand); PAEC (Pakistan); MSHE and NSC (Poland); FCT (Portugal); JINR (Dubna); MON, RosAtom, RAS and RFBR (Russia); MESTD (Serbia); SEIDI and CPAN (Spain); Swiss Funding Agencies (Switzerland); MST (Taipei); ThEPCenter, IPST, STAR and NSTDA (Thailand); TUBITAK and TAEK (Turkey); NASU and SFFR (Ukraine); STFC (United Kingdom); DOE and NSF (USA
Displays of authority in the clinical consultation: a linguistic ethnographic study of the electronic patient record.

The introduction of computers into general practice settings has profoundly changed the dynamics of the clinical consultation. Previous research exploring the impact of the computer (in what has been termed the 'triadic' consultation) has shown that computer use and communication between doctor and patient are intricately coordinated and inseparable. Swinglehurst etÂ al. have recently been critical of the ongoing tendency within health communication research to focus on 'the computer' as a relatively simple 'black box', or as a material presence in the consultation. By re-focussing on the electronic patient record (EPR) and conceptualising this as a complex collection of silent but consequential voices, they have opened up new and more nuanced possibilities for analysis. This orientation makes visible a tension between the immediate contingencies of the interaction as it unfolds moment-by-moment and the more standardised, institutional demands which are embedded in the EPR ('dilemma of attention'). In this paper I extend this work, presenting an in-depth examination of how participants in the consultation manage this tension. I used linguistic ethnographic methods to study 54 video recorded consultations from a dataset collected between 2007 and 2008 in two UK general practices, combining microanalysis of the consultation with ethnographic attention to the wider organisational and institutional context. My analysis draws on the theoretical work of Erving Goffman and Mikhail Bakhtin, incorporating attention to the 'here and now' of the interaction as well as an appreciation of the 'distributed' nature of the EPR, its role in hosting and circulating new voices, and in mediating participants' talk and social practices. It reveals - in apparently fleeting moments of negotiation and contestation - the extent to which the EPR shapes the dynamic construction, display and circulation of authority in the contemporary consultation

Search for new particles decaying to ZZ using final states with leptons and jets with the ATLAS detector in √s = 7 TeV proton–proton collisions

A search is presented for a narrow resonance decaying to a pair of Z   bosons using data corresponding to 1.02 fb[superscript −1] of integrated luminosity collected by the ATLAS experiment from pp collisions at √s = 7 TeV. Events containing either four charged leptons (ℓℓℓℓ) or two charged leptons and two jets (ℓℓjj) are analyzed and found to be consistent with the Standard Model background expectation. Lower limits on a resonance mass are set using the Randall–Sundrum (RS1) graviton model as a benchmark. Using both ℓℓℓℓ and ℓℓjj events, an RS1 graviton with k/[bar over m][subscript pl] = 0.1 and mass between 325 and 845 GeV is excluded at 95% confidence level. In addition, the ℓℓℓℓ events are used to set a model-independent fiducial cross section limit of σ[subscript fid](pp→X→ZZ) < 0.92 pb at 95% confidence level for any new sources of ZZ production with m[subscript ZZ] greater than 300 GeV.European Organization for Nuclear ResearchNational Science Foundation (U.S.)United States.

THE COMPLEX ACCRETION GEOMETRY OF GX 339–4 AS SEEN BY NuSTAR AND SWIFT

We present spectral analyses of five Nuclear Spectroscopic Telescope Array and Swift observations of GX 339–4 taken during a failed outburst during the summer of 2013. These observations cover Eddington luminosity fractions in the range ≈0.9%–6%. Throughout this outburst GX 339–4 stayed in the hard state and all five observations show similar X-ray spectra, with a hard power law with a photon index near 1.6, and significant contribution from reflection. Using simple reflection models we find unrealistically high iron abundances. Allowing for different photon indices for the continuum incident on the reflector relative to the underlying observed continuum results in a statistically better fit and reduced iron abundances. With a photon index around 1.3, the input power law on the reflector is significantly harder than that which is directly observed. We study the influence of different emissivity profiles and geometries and consistently find an improvement when using separate photon indices. The inferred inner accretion disk radius is strongly model dependent, but we do not find evidence for a truncation radius larger than 100 r[subscript g] in any model. The data do not allow independent spin constraints, but the results are consistent with the literature (i.e., a > 0). Our best-fit models indicate an inclination angle in the range 40°–60°, consistent with limits on the orbital inclination but higher than reported in the literature using standard reflection models. The iron line around 6.4 keV is clearly broadened, and we detect a superimposed narrow core as well. This core originates from a fluorescent region outside the influence of the strong gravity of the black hole. Additionally, we discuss possible geometries
Discovery of directional and nondirectional pioneer transcription factors by modeling DNase profile magnitude and shape

We describe protein interaction quantitation (PIQ), a computational method for modeling the magnitude and shape of genome-wide DNase I hypersensitivity profiles to identify transcription factor (TF) binding sites. Through the use of machine-learning techniques, PIQ identified binding sites for >700 TFs from one DNase I hypersensitivity analysis followed by sequencing (DNase-seq) experiment with accuracy comparable to that of chromatin immunoprecipitation followed by sequencing (ChIP-seq). We applied PIQ to analyze DNase-seq data from mouse embryonic stem cells differentiating into prepancreatic and intestinal endoderm. We identified 120 and experimentally validated eight 'pioneer' TF families that dynamically open chromatin. Four pioneer TF families only opened chromatin in one direction from their motifs. Furthermore, we identified 'settler' TFs whose genomic binding is principally governed by proximity to open chromatin. Our results support a model of hierarchical TF binding in which directional and nondirectional pioneer activity shapes the chromatin landscape for population by settler TFs.National Institutes of Health (U.S.) (Common Fund 5UL1DE019581)National Institutes of Health (U.S.) (Common Fund RL1DE019021)National Institutes of Health (U.S.) (Common Fund 5TL1EB008540)National Institutes of Health (U.S.) (Grant 1U01HG007037)National Institutes of Health (U.S.) (Grant 5P01NS055923
Measurement of the CP-violating weak phase $ϕ_s$ and the decay width difference $ΔΓ_s$ using the $B^{0}_{s}→J/ψϕ(1020)$ decay channel in pp collisions at $\sqrt{s} = 8$ TeV

The CP-violating weak phase $ϕ_s$ of the $B^{0}_{s}$ meson and the decay width difference $ΔΓ_s$ of the Bs0 light and heavy mass eigenstates are measured with the CMS detector at the LHC using a data sample of  $B^{0}_{s}→J/ψϕ(1020)→μ^{+}μ^{−}K^{+}K^{−}$ decays. The analysed data set corresponds to an integrated luminosity of 19.7fb$^{−1}$ collected in pp collisions at a centre-of-mass energy of 8TeV . A total of 49 200 reconstructed $B^{0}_{s}$ decays are used to extract the values of $ϕ_s$ and $ΔΓ_s$ by performing a time-dependent and flavour-tagged angular analysis of the $μ^{+}μ^{−}K^{+}K^{−}$ final state. The weak phase is measured to be $ϕ_s$=−0.075±0.097(stat)±0.031(syst) rad , and the decay width difference is $ΔΓ_s$=0.095±0.013(stat)±0.007(syst) ps$^{−1}$
On the Zarankiewicz problem for intersection hypergraphs

Let d and t be fixed positive integers, and let Kd t,...,t denote the complete d-partite hypergraph with t vertices in each of its parts, whose hyperedges are the d-tuples of the vertex set with precisely one element from each part. According to a fundamental theorem of extremal hypergraph theory, due to Erdos [6], the number of hyperedges of a d-uniform hypergraph on n vertices that does not contain Kd t,...,t as a subhypergraph, is nd-1td-1. This bound is not far from being optimal. We address the same problem restricted to intersection hypergraphs of (d-1)-dimensional simplices in Rd. Given an n-element set S of such simplices, let Hd(S) denote the d-uniform hypergraph whose vertices are the elements of S, and a d-tuple is a hyperedge if and only if the corresponding simplices have a point in common. We prove that if Hd(S) does not contain Ktd....t as a subhypergraph, then its number of edges is O(n) if d = 2, and O(nd-1+ε) for any ε>0 if d≥3. This is almost a factor of n better than Erdos's above bound. Our result is tight, apart from the error term ε in the exponent. In particular, for d = 2, we obtain a theorem of Fox and Pach [7], which states that every Kt,t-free intersection graph of n segments in the plane has O(n) edges. The original proof was based on a separator theorem that does not generalize to higher dimensions. The new proof works in any dimension and is simpler: it uses size-sensitive cuttings, a variant of random sampling. © 2016 Elsevier Inc
Measurement of the pseudorapidity and transverse momentum dependence of the elliptic flow of charged particles in lead-lead collisions at root sNN = 2.76 TeV with the ATLAS detector

This Letter describes the measurement of elliptic flow of charged particles in lead–lead collisions at √sNN = 2.76 TeV using the ATLAS detector at the Large Hadron Collider (LHC). The results are based on an integrated luminosity of approximately 7 μb⁻¹. Elliptic flow is measured over a wide region in pseudorapidity, |η| < 2.5, and over a broad range in transverse momentum, 0.5 < pτ < 20 GeV. The elliptic flow parameter v₂ is obtained by correlating individual tracks with the event plane measured using energy deposited in the forward calorimeters. As a function of transverse momentum, v₂(pτ) reaches a maximum at pτ of about 3 GeV, then decreases and becomes weakly dependent on pτ above 7–8 GeV. Over the measured pseudorapidity region, v₂ is found to be only weakly dependent on η, with less variation than observed at lower beam energies. The results are discussed in the context of previous measurements at lower collision energies, as well as recent results from the LHC.G. Aad ... P. Jackson ... L. Lee ... A. Petridis ... N. Soni ...
