PMO as a Key Ingredient of Public Sector Projects’ Success – Position Paper

AbstractThe requirements of public administration institutions are increasing and projects becoming progressively challenging. Managing a project is a complex activity, in particular when it involves many people working over long periods of time and many different stakeholders. This increasing complexity requires management practices and tools that assure an efficient use of resources. In this context, a Project Management Office (PMO) can be of great value. In this position paper we discuss several scenarios for PMO implementation in the public administration sector, as a promoter of project success and a key ingredient for a better resources usage
Long-range angular correlations on the near and away side in p–Pb collisions at sNN=5.02 TeV

AbstractAngular correlations between charged trigger and associated particles are measured by the ALICE detector in p–Pb collisions at a nucleon–nucleon centre-of-mass energy of 5.02 TeV for transverse momentum ranges within 0.5<pT,assoc<pT,trig<4 GeV/c. The correlations are measured over two units of pseudorapidity and full azimuthal angle in different intervals of event multiplicity, and expressed as associated yield per trigger particle. Two long-range ridge-like structures, one on the near side and one on the away side, are observed when the per-trigger yield obtained in low-multiplicity events is subtracted from the one in high-multiplicity events. The excess on the near-side is qualitatively similar to that recently reported by the CMS Collaboration, while the excess on the away-side is reported for the first time. The two-ridge structure projected onto azimuthal angle is quantified with the second and third Fourier coefficients as well as by near-side and away-side yields and widths. The yields on the near side and on the away side are equal within the uncertainties for all studied event multiplicity and pT bins, and the widths show no significant evolution with event multiplicity or pT. These findings suggest that the near-side ridge is accompanied by an essentially identical away-side ridge
Yang–Baxter invariance of the Nappi–Witten model

AbstractWe study Yang–Baxter deformations of the Nappi–Witten model with a prescription invented by Delduc, Magro and Vicedo. The deformations are specified by skew-symmetric classical r-matrices satisfying (modified) classical Yang–Baxter equations. We show that the sigma-model metric is invariant under arbitrary deformations (while the coefficient of B-field is changed) by utilizing the most general classical r-matrix. Furthermore, the coefficient of B-field is determined to be the original value from the requirement that the one-loop β-function should vanish. After all, the Nappi–Witten model is the unique conformal theory within the class of the Yang–Baxter deformations preserving the conformal invariance
On energy functionals, Kähler–Einstein metrics, and the Moser–Trudinger–Onofri neighborhood

AbstractWe prove that the existence of a Kähler–Einstein metric on a Fano manifold is equivalent to the properness of the energy functionals defined by Bando, Chen, Ding, Mabuchi and Tian on the set of Kähler metrics with positive Ricci curvature. We also prove that these energy functionals are bounded from below on this set if and only if one of them is. This answers two questions raised by X.-X. Chen. As an application, we obtain a new proof of the classical Moser–Trudinger–Onofri inequality on the two-sphere, as well as describe a canonical enlargement of the space of Kähler potentials on which this inequality holds on higher-dimensional Fano Kähler–Einstein manifolds
Quasi-supersymmetric G3 unification from intersecting D6-branes on Type IIA orientifolds

AbstractWe construct three quasi-supersymmetric G3 GUT models with S3 symmetry and gauge coupling unification from intersecting D6-branes on Type IIA orientifolds. The Standard Model fermions and Higgs doublets can be embedded into the bifundamental representations in these models, and there is no any other unnecessary massless representation. Especially in Model I with gauge group U(4)3, we just have three-family SM fermions and three pairs of Higgs particles. The G3 gauge symmetry in these models can be broken down to the Standard Model gauge symmetry by introducing light open string states. And 1 TeV scale supersymmetry breaking soft masses imply the reasonable intermediate string scale
Conformal symmetry of the Lange–Neubert evolution equation

AbstractThe Lange–Neubert evolution equation describes the scale dependence of the wave function of a meson built of an infinitely heavy quark and light antiquark at light-like separations, which is the hydrogen atom problem of QCD. It has numerous applications to the studies of B-meson decays. We show that the kernel of this equation can be written in a remarkably compact form, as a logarithm of the generator of special conformal transformation in the light-ray direction. This representation allows one to study solutions of this equation in a very simple and mathematically consistent manner. Generalizing this result, we show that all heavy–light evolution kernels that appear in the renormalization of higher-twist B-meson distribution amplitudes can be written in the same form
Search for physics beyond the standard model in events with a Z boson, jets, and missing transverse energy in pp collisions at s=7 TeV

AbstractA search is presented for physics beyond the standard model (BSM) in events with a Z boson, jets, and missing transverse energy (ETmiss). This signature is motivated by BSM physics scenarios, including supersymmetry. The study is performed using a sample of proton–proton collision data collected at s=7 TeV with the CMS experiment at the LHC, corresponding to an integrated luminosity of 4.98 fb−1. The contributions from the dominant standard model backgrounds are estimated from data using two complementary strategies, the jet-Z balance technique and a method based on modeling ETmiss with data control samples. In the absence of evidence for BSM physics, we set limits on the non-standard-model contributions to event yields in the signal regions and interpret the results in the context of simplified model spectra. Additional information is provided to facilitate tests of other BSM physics models
CSOc superpotentials

AbstractMotivated by their applications to holographic RG flows and hairy black holes in Einstein-scalar systems, we present a collection of superpotentials driving the dynamics of N=2 and N=1 four-dimensional supergravities. These theories arise as consistent truncations of the electric/magnetic families of CSO(p,q,r)c maximal supergravities, with p+q+r=8, discovered by Dall'Agata et al. The N=2 and N=1 truncations describe SU(3) and Z2×SO(3) invariant sectors, respectively, and contain AdS4 solutions preserving N=1,2,3,4 supersymmetry within the full theories, as well as various gauge symmetries. Realisations in terms of non-geometric type IIB as well as geometric massive type IIA backgrounds are also discussed. The aim of this note is to provide easy to handle superpotentials that facilitate the study of gravitational and gauge aspects of the CSO(p,q,r)c maximal supergravities avoiding the technicalities required in their construction
Nonlinear supersymmetry, brane–bulk interactions and super-Higgs without gravity

AbstractWe derive the coupling of a hypermultiplet of N=2 global supersymmetry to the Dirac–Born–Infeld Maxwell theory with linear N=1 and a second nonlinear supersymmetry. At the level of global supersymmetry, this construction corresponds to the interaction with Maxwell brane fields of bulk hypermultiplets, such as the universal dilaton of type IIB strings compactified on a Calabi–Yau manifold. It displays in particular the active role of a four-form field. Constrained N=1 and N=2 superfields and the formulation of the hypermultiplet in its single-tensor version are used to derive the nonlinear realization, allowing a fully off-shell description. Exact results with explicit symmetries and supersymmetries are then obtained. The electric–magnetic dual version of the theory is also derived and the gauge structure of the interaction is exemplified with N=2 nonlinear QED of a charged hypermultiplet. Its Higgs phase describes a novel super-Higgs mechanism without gravity, where the goldstino is combined with half of the hypermultiplet into an N=1 massive vector multiplet
Charge symmetry breaking in dd→He4π0 with WASA-at-COSY

AbstractCharge symmetry breaking (CSB) observables are a suitable experimental tool to examine effects induced by quark masses on the nuclear level. Previous high precision data from TRIUMF and IUCF are currently used to develop a consistent description of CSB within the framework of chiral perturbation theory. In this work the experimental studies on the reaction dd→He4π0 have been extended towards higher excess energies in order to provide information on the contribution of p-waves in the final state. For this, an exclusive measurement has been carried out at a beam momentum of pd=1.2 GeV/c using the WASA-at-COSY facility. The total cross section amounts to σtot=(118±18stat±13sys±8ext) pb and first data on the differential cross section are consistent with s-wave pion production
Identities in transit: the (re)connections and (re)brandings of Berlin's municipal railway infrastructure after 1989

AbstractThis article analyses urban railway infrastructures as landscapes in order to reveal their role as constructions and constructors of collective and individual identities. It does this by introducing the notion of 'identities in transit', a rhetorical category that problematises the tendency to consider the nexus of urban infrastructure and identity formation only during discrete moments and in relation to abstract subjectivities. Specifically, it explores the (re)connections and (re)brandings that Berlin's municipal railway infrastructure, the Stadtschnellbahn (S-Bahn) and Untergrundbahn (U-Bahn), experienced in the years surrounding the fall of the Berlin Wall, and considers their contribution to the formation of post-unification municipal identities. These discussions are historicised and contextualised by an account of the consequences of Berlin's Cold War division on its transport infrastructure. The article then considers the subsequent impact of the city's reunification and how the S- and U-Bahn became a means of constructing more unified municipal identities. It considers the process by which Berlin's municipal railway networks were reconnected after November 1989 and frames this process as a metaphor for both the different durations and protracted process of the city's reunification and the identities these gave rise to. Thereafter, the article argues that the rebranding strategy pursued by one of the city's municipal transport authorities provides one of the earliest examples of an attempt to manufacture a unified identity for the New Berlin. The article highlights that while processes at the municipal level emphasised the unification of collective identities, experiences of the infrastructures themselves often involved persisting divides and forms of subversion and social conflict that highlighted the meeting of more diverse individual identities
Sexual Problems among Japanese Women: Data from an Online Helpline

AbstractIntroductionSexual problems have been more prevalent among East Asian women than those from other areas of the world. However, Japanese women seldom tend to consult their treating physicians as such intimate problems are socially awkward topics to share and may be considered shameful. Presently, there is little data in the literature regarding women's sexual problems in Japan.AimsWe aimed (i) to investigate the types of sexual problems that were reported among Japanese women who had sought online consultations; and (ii) to examine whether factors such as age and family structure (marital status and presence of children) increased the likelihood of sexual problems.MethodsAn online helpline received a total of 316 messages from Japanese women related to sexual problems over a 3‐year period. We evaluated 276 respondents, who provided demographic information such as age and family structure as well as their response to an open‐ended question regarding their sexual problems.Main Outcome MeasuresMain outcome measures were the types of sexual problems reported by Japanese women.ResultsThe majority of respondents were in their 30s (53.6%). Sexual aversion accounted for 42.4% of the complaints, partners' sexual issues for 18.5%, and pain during sex for 16.7%. Family structure significantly correlated with sexual problems (P < 0.001). Women with sexual aversion were more likely to be younger (P = 0.003) and have children (P < 0.001). Women whose partners had sexual issues were more likely to be married (P < 0.001) and have no children (P < 0.001). Women who reported pain during sex were more likely to have no children (P = 0.006).ConclusionSexual aversion was the most common sexual problem among Japanese women who sought help via the online helpline. Family structure was related to sexual problems. More detailed assessments of family structure may be important in better identifying the triggering causes of the reported sexual problems.

Dynamic mineral clouds on HD 189733b. II. Monte Carlo radiative transfer for 3D cloudy exoplanet atmospheres : combining scattering and emission spectra

G.L. and Ch.H. highlight the financial support of the European community under the FP7 ERC starting grant 257431.Context. As the 3D spatial properties of exoplanet atmospheres are being observed in increasing detail by current and new generations of telescopes, the modelling of the 3D scattering effects of cloud forming atmospheres with inhomogeneous opacity structures becomes increasingly important to interpret observational data. Aims. We model the scattering and emission properties of a simulated cloud forming, inhomogeneous opacity, hot Jupiter atmosphere of HD 189733b. We compare our results to available Hubble Space Telescope (HST) and Spitzer data and quantify the effects of 3D multiple scattering on observable properties of the atmosphere. We discuss potential observational properties of HD 189733b for the upcoming Transiting Exoplanet Survey Satellite (TESS) and CHaracterising ExOPlanet Satellite (CHEOPS) missions. Methods. We developed a Monte Carlo radiative transfer code and applied it to post-process output of our 3D radiative-hydrodynamic, cloud formation simulation of HD 189733b. We employed three variance reduction techniques, i.e. next event estimation, survival biasing, and composite emission biasing, to improve signal to noise of the output. For cloud particle scattering events, we constructed a log-normal area distribution from the 3D cloud formation radiative-hydrodynamic results, which is stochastically sampled in order to model the Rayleigh and Mie scattering behaviour of a mixture of grain sizes. Results. Stellar photon packets incident on the eastern dayside hemisphere show predominantly Rayleigh, single-scattering behaviour, while multiple scattering occurs on the western hemisphere. Combined scattered and thermal emitted light predictions are consistent with published HST and Spitzer secondary transit observations. Our model predictions are also consistent with geometric albedo constraints from optical wavelength ground-based polarimetry and HST B band measurements. We predict an apparent geometric albedo for HD 189733b of 0.205 and 0.229, in the TESS and CHEOPS photometric bands respectively. Conclusions. Modelling the 3D geometric scattering effects of clouds on observables of exoplanet atmospheres provides an important contribution to the attempt to determine the cloud properties of these objects. Comparisons between TESS and CHEOPS photometry may provide qualitative information on the cloud properties of nearby hot Jupiter exoplanets.Publisher PDFPeer reviewe

Hetero-oligomerization between the TNF receptor superfamily members CD40, Fas and TRAILR2 modulate CD40 signalling.

TNF receptor superfamily members (TNFRSF) such as CD40, Fas and TRAIL receptor 2 (TRAILR2) participate to the adaptive immune response by eliciting survival, proliferation, differentiation and/or cell death signals. The balance between these signals determines the fate of the immune response. It was previously reported that these receptors are able to self-assemble in the absence of ligand through their extracellular regions. However, the role of this oligomerization is not well understood, and none of the proposed hypotheses take into account potential hetero-association of receptors. Using CD40 as bait in a flow cytometry Förster resonance energy transfer assay, TNFRSF members with known functions in B cells were probed for interactions. Both Fas and TRAILR2 associated with CD40. Immunoprecipitation experiments confirmed the interaction of CD40 with Fas at the endogenous levels in a BJAB B-cell lymphoma cell line deficient for TRAILR2. TRAILR2-expressing BJAB cells displayed a robust CD40-TRAILR2 interaction at the expense of the CD40-Fas interaction. The same results were obtained by proximity ligation assay, using TRAILR2-positive and -negative BJAB cells and primary human B cells. Expression of the extracellular domains of Fas or TRAILR2 with a glycolipid membrane anchor specifically reduced the intrinsic signalling pathway of CD40 in 293T cells. Conversely, BJAB cells lacking endogenous Fas or TRAILR2 showed an increased NF-κB response to CD40L. Finally, upregulation of TRAILR2 in primary human B cells correlated with reduced NF-κB activation and reduced proliferation in response to CD40L. Altogether, these data reveal that selective interactions between different TNFRSF members may modulate ligand-induced responses upstream signalling events
Measurements of differential production cross sections for a Z boson in association with jets in pp collisions at sqrt(s) = 8 TeV

Cross sections for the production of a Z boson in association with jets in proton-proton collisions at a centre-of-mass energy of s√=8 TeV are measured using a data sample collected by the CMS experiment at the LHC corresponding to 19.6 fb−1. Differential cross sections are presented as functions of up to three observables that describe the jet kinematics and the jet activity. Correlations between the azimuthal directions and the rapidities of the jets and the Z boson are studied in detail. The predictions of a number of multileg generators with leading or next-to-leading order accuracy are compared with the measurements. The comparison shows the importance of including multi-parton contributions in the matrix elements and the improvement in the predictions when next-to-leading order terms are included
Final COMPASS results on the deuteron spin-dependent structure function g1dand the Bjorken sum rule

Final results are presented from the inclusive measurement of deep-inelastic polarised-muon scattering on longitudinally polarised deuterons using a 6LiD target. The data were taken at 160 GeV beam energy and the results are shown for the kinematic range View the MathML source in photon virtuality, 0.004<x<0.7 in the Bjorken scaling variable and View the MathML source in the mass of the hadronic final state. The deuteron double-spin asymmetry View the MathML source and the deuteron longitudinal-spin structure function View the MathML source are presented in bins of x   and Q2. Towards lowest accessible values of x  , View the MathML source decreases and becomes consistent with zero within uncertainties. The presented final View the MathML source values together with the recently published final View the MathML source values of COMPASS are used to again evaluate the Bjorken sum rule and perform the QCD fit to the g1 world data at next-to-leading order of the strong coupling constant. In both cases, changes in central values of the resulting numbers are well within statistical uncertainties. The flavour-singlet axial charge a0, which is identified in the View the MathML source renormalisation scheme with the total contribution of quark helicities to the nucleon spin, is extracted at next-to-leading order accuracy from only the COMPASS deuteron data: View the MathML source. Together with the recent results on the proton spin structure function View the MathML source, the results on View the MathML source constitute the COMPASS legacy on the measurements of g1 through inclusive spin-dependent deep inelastic scattering
Tunable Light–Matter Interaction and the Role of Hyperbolicity in Graphene–hBN System

Hexagonal boron nitride (hBN) is a natural hyperbolic material, which can also accommodate highly dispersive surface phonon-polariton modes. In this paper, we examine theoretically the mid-infrared optical properties of graphene–hBN heterostructures derived from their coupled plasmon–phonon modes. We find that the graphene plasmon couples differently with the phonons of the two Reststrahlen bands, owing to their different hyperbolicity. This also leads to distinctively different interaction between an external quantum emitter and the plasmon–phonon modes in the two bands, leading to substantial modification of its spectrum. The coupling to graphene plasmons allows for additional gate tunability in the Purcell factor and narrow dips in its emission spectra.National Science Foundation (U.S.) (CMMI-1120724)United States.

Search for new physics in the multijet and missing transverse momentum final state in proton-proton collisions at √s = 8 TeV

A search for new physics is performed in multijet events with large missing transverse momentum produced in proton-proton collisions at √s = 8 TeV using a data sample corresponding to an integrated luminosity of 19.5 fb -1 collected with the CMS detector at the LHC. The data sample is divided into three jet multiplicity categories (3-5, 6-7, and ≥8 jets), and studied further in bins of two variables: the scalar sum of jet transverse momenta and the missing transverse momentum. The observed numbers of events in various categories are consistent with backgrounds expected from standard model processes. Exclusion limits are presented for several simplified supersymmetric models of squark or gluino pair production.The Scientific and Technical Research Council of Turkey, and Turkish Atomic Energy Authorit
