description: The two-loop electroweak corrections to the anomalous magnetic moment of the muon, generated by fermionic loops, are calculated. An interesting role of the top quark in the anomaly cancellation is observed. New corrections, including terms of order $G_μαm_t^2$, are computed and a class of diagrams previously thought to vanish are found to be important. The total fermionic correction is $-(23\pm 3) \times 10^{-11}$ which decreases the electroweak effects on $g-2$, predicted from one-loop calculations, by 12\%. We give an updated theoretical prediction for $g-2$ of the muon.

D1.3 REPORT FROM THE FOCUS GROUPS WITH CITIZENS

description: This deliverable report presents a thorough analysis of data collected from a series of 14 focus groups and 10 individual interviews conducted in the context of T1.3 ’Focus Groups with Citizens’. The task aimed to gain a multi-stakeholder perspective on what affects trust in science, and how it could be enhanced. To achieve this objective, focus groups and interviews were conducted across three different stakeholder groups: general public, journalists and researchers.

The analysis is guided by the following objectives:

To examine the perspectives of different stakeholders (general public, journalists, researchers) regarding the actors responsible for upholding trust in science.

To understand how different actors may hinder or facilitate trust.

To derive recommendations for actions that should be taken for enhancing trust in science, across different actors.

The main findings include the following:

Across the three stakeholder groups, participants mostly referred to policymakers (including government, politicians, and legislators at the national and international level), media actors, scientific actors and educational actors as the ones who bear the greatest responsibility for safeguarding trust in science.

Policymakers, media, scientific and technological actors were regarded as occupying a dual function: as facilitators of trust and as hinderers of trust.

In terms of who should take actions to enhance trust in science, and what those actions might be, there was variation across stakeholder groups.

Participants in the general public groups considered this to be the role of policymakers, as indicated by the number of actions suggested.

Participants in the journalists’ and researchers’ group were reflective of their own role in enhancing the public’s trust in science. In both these groups, participants underlined the institutional constraints that may influence how science is communicated and how the general public is engaged.

Our analysis expands our theoretical understanding of the Stewards of Trust by pointing to additional actors whose role was further explored in WP3 in Deliverable 3.2: educational actors and policymakers. This report will also contribute to the development of the VERITY recommendations for Stewards of Trust for tackling mistrust and strengthening the open science and science citizen co-creation of research and innovation (R&I).

DeDonder-Weyl theory and a hypercomplex extension of quantum mechanics to field theory

description: A quantization of field theory based on the DeDonder-Weyl covariant Hamiltonian formulation is discussed. A hypercomplex extension of quantum mechanics, in which the space-time Clifford algebra replaces that of the complex numbers, appears as a result of quantization of Poisson brackets of differential forms put forward for the DeDonder-Weyl formulation earlier. The proposed covariant hypercomplex Schrödinger equation is shown to lead in the classical limit to the DeDonder-Weyl Hamilton-Jacobi equation and to obey the Ehrenfest principle in the sense that the DeDonder-Weyl canonical field equations are satisfied for the expectation values of properly chosen operators.

description: Os indicadores de atenção online têm sido debatidos no contexto da altmetria, que se concentra na compreensão do impacto da pesquisa na web social. Mais do que analisar os aspectos quantitativos dos dados, a abordagem altmétrica deve usar dados semânticos ricos para investigar o público interagindo com artigos científicos e o contexto de interações. Propomos que os aspectos estruturais e conversacionais do Twitter sejam considerados nos estudos de altmetria por meio da análise dos perfis, seguidores, menções e retweets. A avaliação desses aspectos no microblog permite a caracterização dos usuários, a verificação do grau de exposição, recomendação e de reprodução que sustentam os valores altmétricos de um artigo, bem como o mapeamento e compreensão de sua "Rede de Comunidades de Atenção". A proposta é aplicada ao artigo 'Tratamento Farmacológico da Obesidade', uma extensa revisão dos critérios de avaliação da eficácia dos tratamentos anti-obesidade e dos agentes farmacológicos derivados, publicado nos Arquivos Bras Metab da Endocrinologia, com 736 tweets de 134 usuários. O artigo alcançou uma exposição combinada de mais de 459.018 seguidores e um alto nível de reprodução (67,26%) e recomendação (28,53%). Quanto aos usuários que compartilham o artigo verificou-se perfis individuais com auto apresentação centrada em questões pessoais e forte engajamento cívico e político. Perfis profissionais e institucionais da cena política nacional são frequentemente mencionados. Ao analisar o conteúdo dos tweets, notamos que a pontuação altmétrica do trabalho é resultado de seu uso estratégico como um recurso de ativismo online e instrumento de digital advocacy, usado para a mobilização de partes interessadas para atividades de conscientização e apoio. A rede de comunidade de atenção apresenta nós relativamente próximos e nela os usuários assumem papéis bem definidos. A perspectiva deste estudo pode ajudar a entender o impacto social da altmetria e mais pesquisas são necessárias para confirmar isso

description: We show that the electronic structure of the low-energy bands in the small angle-twisted bilayer graphene consists of a series of semi-metallic and topological phases. In particular we are able to prove, using an approximate low-energy particle-hole symmetry, that the gapped set of bands that exist around all magic angles has what we conjecture to be a stable topological index stabilized by a magnetic symmetry and reflected in the odd winding of the Wilson loop in the Moiré BZ. The approximate, emergent particle-hole symmetry is essential to the topology of graphene: when strongly broken, non-topological phases can appear. Our paper underpins topology as the crucial ingredient to the description of low-energy graphene. We provide a $4$-band short range tight-binding model whose $2$ lower bands have the same topology, symmetry, and flatness as those of the twisted graphene, and which can be used as an effective low-energy model. We then perform large-scale ($11000$ atoms per unit cell, 40 days per $\bf k$-point computing time) ab-initio calculations of a series of small angles, from $3^\circ$ to $1^\circ$, which show a more complex and somewhat qualitatively different evolution of the symmetry of the low-energy bands than that of the theoretical Moiré model, but which confirms the topological nature of the system. At certain angles, we find no insulating filling in graphene at $-4$ electrons per Moiré unit cell. The ab-initio evolution of gaps tends to differ from that of the continuum Moiré model.

description: Reducing energy dissipation is a central goal of classical and quantum technologies. Optics achieved great success in bringing down power consumption of long-distance communication links. With the rise of mobile, quantum and cloud technologies, it is essential to extend this success to shorter links. Electro-optic modulators are a crucial contributor of dissipation in such links. Numerous variations on important mechanisms such as free-carrier modulation and the Pockels effect are currently pursued, but there are few investigations of mechanical motion as an electro-optic mechanism in silicon. In this work, we demonstrate electrical driving and optical read-out of a 7.2 GHz mechanical mode of a silicon photonic waveguide. The electrical driving is capacitive and can be implemented in any material system. The measurements show that the mechanically-mediated optical phase modulation is two orders of magnitude more efficient than the background phase modulation in our system. Our demonstration is an important step towards efficient opto-electro-mechanical devices in a scalable photonic platform.

description: We present near-IR imaging polarimetry of five classical FU Ori-type objects (FU Ori, V1057 Cyg, V1515 Cyg, V1735 Cyg, Z CMa) with a $\sim$0\farcs1 resolution observed using HiCIAO+AO188 at Subaru Telescope. We observed scattered light associated with circumstellar dust around four of them (i.e., all but V1515 Cyg). Their polarized intensity distribution shows a variety of morphologies with arms, tails or streams, spikes and fragmented distributions, many of which were reported in our previous paper. The morphologies of these reflection nebulae significantly differ from many other normal young stellar objects (Class I-II objects). These structures are attributed to gravitationally unstable disks, trails of clump ejections, dust blown by a wind or a jet, and a stellar companion. We can consistently explain our results with the scenario that their accretion outbursts (FUor outbursts) are triggered by gravitationally fragmenting disks, and with the hypothesis that many low-mass young stellar objects experience such outbursts.

description: The Landau gauge quark propagator in momentum space is investigated using the O(a)-improved Sheikholeslami--Wohlert (SW) quark action with a tree-level mean-field improved coefficient c_sw. We have studied the unimproved definition of the quark propagator, as well as two different tree-level O(a)-improved propagators. The ultraviolet behavior of the free lattice propagator is studied for each of these in order to establish which of them provides the most reliable description of the quark propagator up to the medium momentum regime. A general method of tree-level correction is introduced. This exploits asymptotic freedom and removes much of the trivial lattice artifacts at medium to high momenta. We obtain results for the quark propagator which are qualitatively similar to those typically used in quark models. A simple extrapolation of the infrared quark mass M(p^2=0) to the chiral limit gives (298+/-8+/-30) MeV, which is consistent with phenomenological expectations.

The decay $ρ^0 \to π^+ π^- γ$ and the chiral invariant interactions of vector mesons

description: Using the close relationship between the low--energy constants of chiral perturbation theory and the chiral invariant interactions of the vector meson resonances with the pseudoscalar mesons, we investigate the process $ρ^0 \ra π^+ π^- γ$. Compared with the contribution from the pure bremsstrahlung mechanism, we find an enhancement of the decay rate near the endpoint of the photon energy spectrum. Such a particular shape of the differential decay rate has indeed been observed experimentally and turns out to be an important confirmation of the theoretical concept of chiral vector meson dominance.

Search for heavy resonances decaying into two Higgs bosons or into a Higgs boson and a W or Z boson in proton-proton collisions at 13 TeV

Year: 2018
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: A search is presented for massive narrow resonances decaying either into two Higgs bosons, or into a Higgs boson and a W or Z boson. The decay channels considered are HH $\to \mathrm{b\overline{b}}τ^{+}τ^{-}$ and VH $\to \mathrm{q\overline{q}}τ^{+}τ^{-}$, where H denotes the Higgs boson, and V denotes the W or Z boson. This analysis is based on a data sample of proton-proton collisions collected at a center-of-mass energy of 13 TeV by the CMS Collaboration, corresponding to an integrated luminosity of 35.9 fb$^{-1}$. For the TeV-scale mass resonances considered, substructure techniques provide ways to differentiate among the hadronization products from vector boson decays to quarks, Higgs boson decays to bottom quarks, and quark- or gluon-induced jets. Reconstruction techniques are used that have been specifically optimized to select events in which the tau lepton pair is highly boosted. The observed data are consistent with standard model expectations and upper limits are set at 95% confidence level on the product of cross section and branching fraction for resonance masses between 0.9 and 4.0 TeV. Exclusion limits are set in the context of bulk radion and graviton models: spin-0 radion resonances are excluded below a mass of 2.7 TeV at 95% confidence level. In the spin-1 heavy vector triplet framework, mass-degenerate W' and Z' resonances with dominant couplings to the standard model gauge bosons are excluded below a mass of 2.8 TeV at 95% confidence level. There are the first limits for these decay channels at $\sqrt{s} =$ 13 TeV.

Generalized Hamiltonian Formalism of (2+1)-Dimensional Non-Linear $σ$-Model in Polynomial Formulation

Year: 1998
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We investigate the canonical structure of the (2+1)-dimensional non-linear $σ$ model in a $polynomial$ formulation. A current density defined in the non-linear $σ$ model is a vector field which satisfies a $formal$ flatness (or pure gauge) condition. It is the polynomial formulation in which the vector field is regarded as a dynamical variable on which the flatness condition is imposed as a constraint condition by introducing a Lagrange multiplier field. The model so formulated has gauge symmetry under a transformation of the Lagrange multiplier field. We construct the generalized Hamiltonian formalism of the model explicitly by using the Dirac method for constrained systems. We derive three types of the pre-gauge-fixing Hamiltonian systems: In the first system, the current algebra is realized as the fundamental Dirac Brackets. The second one manifests the similar canonical structure as the Chern-Simons or BF theories. In the last one, there appears an interesting interaction as the dynamical variables are coupled to their conjugate momenta via the covariant derivative.

description: The gamma-ray light curves and spectra are presented for a set of theoretical Type Ia supernova models including deflagration, detonation, delayed detonation, and pulsating delayed detonations of Chandrasekhar mass white dwarfs as well as merger scenarios that may involve more than the Chandrasekhar mass and helium detonations of sub-Chandrasekhar mass white dwarfs. The results have been obtained with a Monte Carlo radiation transport scheme which takes into account all relevant gamma-transitions and interaction processes. The result is a set of accurate line profiles which are characteristic of the initial Ni-mass distribution of the supernova models. The gamma-rays probe the isotopic rather than just the elemental distribution of the radioactive elements in the ejecta. Details of the line profiles including the line width, shift with respect to the rest frame, and line ratios are discussed. With sufficient energy and temporal resolution, different model scenarios can clearly be distinguished. Observational strategies are discussed for current and immediately upcoming generations of satellites (CGRO and INTEGRAL) as well as projected future missions including concepts such as Laue telescopes. With CGRO, it is currently possible with sufficiently early observations (near optical maximum) to distinguish helium detonations from explosions of Chandrasekhar mass progenitors and of those involving mergers up to a distance of about 15 Mpc. This translates into one target of opportunity every eight years. SNe Ia up to about 10 Mpc would allow detailed CGRO studies of line ratios of Co lines.

description: In order to draw in and compass gas (most usually air) into the gas turbines, compressor section is designed. Then, the compressed air will be combined with fuel to generate heat and extract power. Blades of the compressor section of the gas turbine can be produced by machining operations. Machining operations of turbine blades by using 4 and 5 Axis CNC machine tools are always with complexities and challenges which can be analyzed and optimized. So, research works which can increase efficiency of blades production are always in attention of manufacturing companies.
To optimize machining operations, finite element analysis of produced turbine blades is implemented by using the Abaqus software. So, stress, strain and deformation of blades in machining operations are obtained and analyzed. Also, the AdvantEdge software is used to predict generated heat as well as residual stress of produced blades by using machining operation.
The optimization technique based on the genetic algorithm is used in order to increase efficiency of part manufacturing. Minimizing the residual stress of produced blades is one of the important objective function of the project. Maximizing tool life is another important economy objective function of the optimization process which should be maximized. Surface roughness is also another objective function which should be minimized.
As a result, modified G-Codes of machining operations regarding optimized condition will be generated in order to increase efficiency of blade manufacturing process.

description: As a step towards clarifying the ionization mechanism of LINERs, we have used the Hubble Space Telescope Faint Object Spectrograph to obtain an ultraviolet spectrum of the nucleus of NGC 6500. Compared with more luminous Seyfert nuclei, the emission-line spectrum of NGC 6500 is remarkable for its low-excitation character: C III], C II], and Mg II are the strongest collisionally excited lines in the UV, and C IV is not detected. The fast shock models of Dopita & Sutherland (1995, 1996) are a poor match to the observed spectrum, as they predict much stronger emission than is observed for high-excitation lines such as C IV. Photoionization by an obscured nonstellar continuum source, or possibly ionization by slower (100 km/s) shocks, are more likely explanations for the emission-line ratios. The origin of the UV continuum is unclear; its overall spectral shape is reasonably well matched by spectral evolution models for single-burst populations with ages in the range 70-100 Myr, but no definite absorption features from young stars are present. Alternately, the UV continuum (or some fraction of it) may be scattered radiation from a hidden active nucleus. We tentatively detect a broad He II 4686 emission feature, which may be due to Wolf-Rayet stars, although the UV spectrum does not show any clear Wolf-Rayet signatures. We also find that NGC 6500 is weakly detected in an archival ROSAT HRI image with a luminosity of 5 x 10^40 erg/s in the 0.1-2.4 keV band, within the normal range for LINERs.

description: We study BPS states which arise in compactifications of M-theory on Calabi-Yau manifolds. In particular, we are interested in the spectrum of the particles obtained by wrapping M2-brane on a two-cycle in the CY manifold X. We compute the Euler characteristics of the moduli space of genus zero curves which land in a holomorphic four-cycle $S \subset X$. We use M. Kontsevich's method which reduces the problem to summing over trees and observe the discrepancy with the predictions of local mirror symmetry. We then turn this discrepancy into a supporting evidence in favor of existence of extra moduli of M2-branes which consists of the choice of a flat U(1) connection recently suggested by C. Vafa and partially confirm this by counting of the arbitrary genus curves of bi-degree (2,n) in $\IP^1 \times \IP^1$ (this part has been done together with Barak Kol). We also make a conjecture concerning the counting of higher genus curves using second quantized Penner model and discuss possible applications to the string theory of two-dimensional QCD.

Its quantum correlations are analyzed using recent results on quantum information theory, looking for the final state which has the maximal amount of GHZ-like correlations. This state allows for a statistical dismissal of local realism stronger than the one obtained using any entangled state of two spin one-half particles.

description: There are many ways to account for the return on investment (ROI) in healthcare: improved communication, teamwork, culture, patient satisfaction, staff satisfaction, and clinical outcomes are but a few. Some of these are easier to quantify and associate to an intervention than others. What if the outcomes listed were not just independent results, but beget one another? In 2001, the Society of Obstetricians and Gynaecologists of Canada created the Managing Obstetrical Risk Efficiently (MOREOB) programme, to improve healthcare culture and patient outcomes in obstetrics by leveraging front-line ownership. Our study provides evidence that MOREOB lowers the frequency and cost of reportable events in maternity units. We sought to review the impact of this intervention on the frequency and cost of reportable events at the insurer level of a clinically focused, three-year interprofessional culture change intervention applied to the maternity unit. We compared the impact of reportable events both in the obstetrical and in the non-obstetrical areas of the same hospitals during the same time periods. We analysed these data using an interrupted time series (ITS) design, among 34 Ontario Canada hospitals. The ITS design assessed changes in the frequency and cost of reportable events before and after the implementation of the intervention. The method was ideally suited as the various maternity units had differing programme commencement and completion dates. The frequency of reportable events showed little change during the three-year intervention. As culture change grew, the changes in behaviour and processes that impact patient outcomes took longer to accrue. A large reduction in the frequency of reportable events occurred in the following three-year (14% reduction) and six-year (25% reduction) tranches. Our results show statistically significant reductions in the frequency and costs associated with reportable events at the level of an insurer. The results also give insight as to the investment of time required to achieve a level of sustainability.

description: A study of the radiative neutrino counting reaction $e^+ e^- \to ν{\bar ν} γ$ at LEP1 and LEP2 energies is presented. An approximate expression for the spectrum of the observed photon is derived within the framework of the $p_t$-dependent structure function approach. This is compared with an exact expression and found in agreement within the foreseen experimental accuracy. This model describing single-photon radiation can be applied to the more general case of initial-state single-photon emission accompanying invisible final-state events. Higher-order QED corrections due to undetected initial-state radiation are also included. The implementation in a Monte Carlo event generator is briefly described.

description: In the CA3ViAR (Composite fan Aerodynamic, Aeroelastic, and Aeroacoustic Validation Rig) project, a composite lowtransonic fan is designed and tested. The aim is a scaled ultrahigh bypass ratio (UHBR) fan with state-of-the-art aerodynamic performance and composite rotor blades, which features aeroelastic phenomena, e.g. forced response by inlet distortions and flutter, under certain operating points within the wind tunnel. In this paper, the aerodynamic and aeroelastic design process starting from the overall performance specifications to a threedimensional numerical model is described. A target of eigenfrequency and twist-to-plunge ratio is specified such that flutter occurs at desired operating conditions with a sufficient margin with respect to the working line. Different materials and layups of the composite blade are analyzed to reach the structural target. The fan should serve as an open test case to advance the future research on aerodynamic, aeroelastic, and aeroacoustic performance investigations in a wide range of operating conditions. A preliminary fan stage design is presented in this paper.
Singular Localised Boundary-Domain Integral Equations of Acoustic Scattering by Inhomogeneous Anisotropic Obstacle

description: We consider the time-harmonic acoustic wave scattering by a bounded {\it anisotropic inhomogeneity} embedded in an unbounded {\it anisotropic} homogeneous medium. The material parameters may have discontinuities across the interface between the inhomogeneous interior and homogeneous exterior regions. The corresponding mathematical problem is formulated as a transmission problems for a second order elliptic partial differential equation of Helmholtz type with discontinuous variable coefficients. Using a localised quasi-parametrix based on the harmonic fundamental solution, the transmission problem for arbitrary values of the frequency parameter is reduced equivalently to a system of {\it singular localised boundary-domain integral equations}. Fredholm properties of the corresponding {\it localised boundary-domain integral operator} are studied and its invertibility is established in appropriate Sobolev-Slobodetskii and Bessel potential spaces, which implies existence and uniqueness results for the localised boundary-domain integral equations system and the corresponding acoustic scattering transmission problem.

Hydrodynamics of the stream-disk impact in interacting binaries

Publisher: name: arXiv
Year: 1997
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We use hydrodynamic simulations to provide quantitative estimates of the effects of the impact of the accretion stream on disks in interacting binaries. For low accretion rates, efficient radiative cooling of the hotspot region can occur, and the primary consequence of the stream impact is stream overflow toward smaller disk radii. The stream is well described by a ballistic trajectory, but larger masses of gas are swept up and overflow at smaller, but still highly supersonic, velocities. If cooling is inefficient, overflow still occurs, but there is no coherent stream inward of the disk rim. Qualitatively, the resulting structure appears as a bulge extending downstream along the disk rim. We calculate the mass fraction and velocity of the overflowing component as a function of the important system parameters, and discuss the implications of the results for X-ray observations and doppler tomography of cataclysmic variables, low-mass X-ray binaries and supersoft X-ray sources.

The variable quality of metadata about biological samples used in biomedical experiments

description: We present an analytical study of the quality of metadata about samples used in biomedical experiments. The metadata under analysis are stored in two well-known databases: BioSample---a repository managed by the National Center for Biotechnology Information (NCBI), and BioSamples---a repository managed by the European Bioinformatics Institute (EBI). We tested whether 11.4M sample metadata records in the two repositories are populated with values that fulfill the stated requirements for such values. Our study revealed multiple anomalies in the metadata. Most metadata field names and their values are not standardized or controlled. Even simple binary or numeric fields are often populated with inadequate values of different data types. By clustering metadata field names, we discovered there are often many distinct ways to represent the same aspect of a sample. Overall, the metadata we analyzed reveal that there is a lack of principled mechanisms to enforce and validate metadata requirements. The significant aberrancies that we found in the metadata are likely to impede search and secondary use of the associated datasets.

description: Forging tools are exposed to cyclically changing thermo-mechanical stress conditions leading to its failure. Damage phenomena on the tool engraving cannot be entirely avoided by hardening the surface, as this leads to a more brittle behaviour and thus to lower ductility of the material, which can intensify the occurring damage effects. The forming of steel below the recrystallisation temperature in the metastable austenite area, known as ausforming, offers the possibility to increase strength and hardness without affecting ductile properties, due to simultaneous grain refinement. In this study, ausforming was used to produce forging dies with increased wear resistance from tool steel X37CrMoV5-1 (AISI H11) by achieving higher hardness in the surface area while maintaining a ductile base material. Suitable forming and tempering parameters were derived from previous studies in which ausformed cups from tool steel X37CrMoV5-1 (AISI H11) with a downscaled geometry have been investigated in mechanical pulsation tests. To achieve comparable properties, a process route with adapted surface-cooling conditions, a global true plastic strain of φ = 0.25 and a tempering temperature of 300 °C were applied. Further, the ausformed dies were compared with conventionally forged dies. The metallographic analysis and hardness measurements show that an increased hardness in the surface area can also be obtained for the actual formed dies. In order to see the influence of the thermomechanical alternating load on the die engraving under forging conditions, the performance of the ausformed tool will be investigated in service-life-time tests and compared to warm-formed and machined reference tools.

Continuum limit of fishnet graphs and AdS sigma model

description: We consider the continuum limit of 4d planar fishnet diagrams using integrable spin chain methods borrowed from the $\mathcal{N}=4$ Super-Yang-Mills theory. These techniques give us control on the scaling dimensions of single-trace operators for all values of the coupling constant in the fishnet theory. We use them to study the thermodynamical limit of the BMN operator corresponding to the spin chain ferromagnetic vacuum. We find that its scaling dimension exhibits a critical behaviour when the coupling constant approaches Zamolodchikov's critical coupling. Analysis close to that point suggests that the continuum limit of the fishnet graphs is controlled by the two-dimensional $AdS_{5}$ non-linear sigma model. More generally, we present evidence that the fishnet diagrams define an integrable lattice regularization of the $AdS_{5}$ model. A system of massless TBA equations is derived for the tachyon energy by dualizing the TBA equations of the weakly coupled planar $\mathcal{N}=4$ SYM theory.
