description: The determination of $|V_{cb}|$ from exclusive semileptonic $B\to D^*\ellν$ decays is sensitive to the choice of form factor parametrization. Larger $|V_{cb}|$ values are obtained fitting the BGL versus the CLN parametrization to recent Belle measurements. For the BGL parametrization, published fits use different numbers of parameters. We propose a method based on nested hypothesis tests to determine the optimal number of BGL parameters to fit the data, and find that six parameters are optimal to fit the Belle tagged and unfolded measurement. We further explore the differences between fits that use different numbers of parameters. The fits which yield $|V_{cb}|$ values in better agreement with determinations from inclusive semileptonic decays, tend to exhibit tensions with heavy quark symmetry expectations. These have to be resolved before the determinations of $|V_{cb}|$ from exclusive and inclusive decays can be considered understood.

description: We study the magnetization plateau at a third of the saturation magnetization of the S=1/2 trimerized XXZ spin chain at T=0. The appearance of the plateau depends on the values of the XXZ anisotropy and the magnitude of the trimerization. This plateauful-plateauless transition is a quantum phase transition of the Berezinskii-Kosterlitz-Thouless type, which is difficult to precisely detect from the numerical data. To determine the phase boundary line of this transition precisely, we use the level crossing of low-lying excitations obtained from the numerical diagonalization. We also discuss the S=1/2 ferromagnetic-ferromagnetic-antiferromagnetic chain.

description: We analyze $D \to P V$, $D \to PP$ and $D \to VV$ decays within a model developed to describe the semileptonic decays $D \to V l ν_l$ and $D\to P l ν_l$. This model combines the heavy quark effective Lagrangian and chiral perturbation theory. We determine amplitudes for decays in which the direct weak annihilation of the initial $D$ meson is absent or negligible, and in which the final state interactions are small. This analysis reduces the arbitrariness in the choice of model parameters. The calculated decay widths are in good agreement with the experimental results.

description: Background Quinolones are important antibiotics and belong to a family of synthetic broad-spectrum drugs. Resistance to quinolones can be chromosomally encoded or plasmid-mediated (PMQR). One PMQR mechanism is mediated by Qnr proteins, which are encoded by different qnr-genes. To better understand the qnr PMQR pathway as well as the distribution of qnr genes, Escherichia (E.) coli isolates recovered in 2017 from bovine and swine origin were phenotypically and genotypically characterized. Methods E. coli isolates from the German National Reference Laboratory for Antimicrobial Resistance were investigated. The isolates were received in the German national monitoring program for antimicrobial resistance in zoonotic bacteria. Antimicrobial resistance was determined by broth microdilution according to CLSI guidelines. MIC values were evaluated using EUCAST epidemiological cut-off values. E. coli from bovine as well as from swine origin, resistant to quinolones were subjected to six different qnr-PCRs to identify the respective variants, XbaI-PFGE, S1-PFGE and whole genome sequencing (WGS). Results Of 3,425 E. coli tested, 351 isolates from bovine and swine origin were classified as quinolone-resistant (MICNAL ≥16 mg/L and/or MICCIP ≥0.06 mg/L). The most abundant qnr-variant in bovine as well as swine originated isolates was qnrS, followed by qnrA. PFGE profiling with XbaI-digestion demonstrated a rather high heterogeneity. The highly diverse PFGE pattern did not indicate an association to a predominant E. coli clone spreading via vertical transmission nor to the origin of the sample matrix-wise. Also, S1-PFGE plasmid profiling showed a variety of extrachromosomal elements of various sizes. Also, WGS of those isolates confirmed the high genetic diversity of the quinolone-resistant E. coli strains. Conclusions Quinolone-resistance could not be attributed to a specific lineage of E. coli nor to the matrix-origin of the isolate. Further analysis is needed for better understanding the plasmid diversity within qnr-harboring E. coli and the prerequisites of their spread.

description: We perform a unified systematic analysis of $d+1$ dimensional, spin $\ell$ representations of the isometry algebra of the maximally symmetric spacetimes AdS$_{d+1}$, $\mathbb{R}_{1,d}$ and dS$_{d+1}$. This allows us to explicitly construct the effective low-energy bulk equations of motion obeyed by linear fields, as the eigenvalue equation for the quadratic Casimir differential operator. We show that the bulk description of a conformal family is given by the Fierz-Pauli system of equations. For $\ell = 2$ this is a massive gravity theory, while for $\ell = 2$ conserved currents we obtain Einstein gravity and covariant gauge fixing conditions. This analysis provides a direct algebraic derivation of the familiar AdS holographic dictionary at low energies, with analogous results for Minkowski and de Sitter spacetimes.

description: The algebraic dichotomy conjecture for Constraint Satisfaction Problems (CSPs) of reducts of (infinite) finitely bounded homogeneous structures states that such CSPs are polynomial-time tractable when the model-complete core of the template has a pseudo-Siggers polymorphism, and NP-complete otherwise. One of the important questions related to this conjecture is whether, similarly to the case of finite structures, the condition of having a pseudo-Siggers polymorphism can be replaced by the condition of having polymorphisms satisfying a fixed set of identities of height 1, i.e., identities which do not contain any nesting of functional symbols. We provide a negative answer to this question by constructing for each non-trivial set of height 1 identities a structure whose polymorphisms do not satisfy these identities, but whose CSP is tractable nevertheless. An equivalent formulation of the dichotomy conjecture characterizes tractability of the CSP via the local satisfaction of non-trivial height 1 identities by polymorphisms of the structure. We show that local satisfaction and global satisfaction of non-trivial height 1 identities differ for $ω$-categorical structures with less than double exponential orbit growth, thereby resolving one of the main open problems in the algebraic theory of such structures.

description: We show that Renyi entropies of subregions can be used to distinguish when the entire system is in a microcanonical ensemble from when it is in a canonical ensemble, at least in theories holographically dual to gravity. Simple expressions are provided for these Renyi entropies in a particular thermodynamic limit with high energy density and fixed fractional size of the subregion. Holographically, the Renyi entropies are determined by the areas of cosmic branes inserted into the bulk spacetime. They differ between a microcanonical and a canonical ensemble because the two ensembles provide different boundary conditions for the gravitational theory under which cosmic branes lead to different backreacted geometries. This is in contrast to the von Neumann entropy which is more coarse-grained and does not differentiate microcanonical ensembles from canonical ensembles.

description: In this paper we use all available baryon acoustic oscillation, Hubble parameter, and quasar angular size data to constrain six dark energy cosmological models, both spatially flat and non-flat. Depending on the model and data combination considered, these data mildly favor closed spatial hypersurfaces (by as much as $1.7σ$) and dark energy dynamics (up to a little over $2σ$) over a cosmological constant $Λ$. The data also favor, at $1.8σ$ to $3.4σ$, depending on the model and data combination, a lower Hubble constant than what is measured from the local expansion rate.

description: The phase transition in a 3D array of classical anharmonic oscillators with harmonic nearest-neighbour coupling (discrete $ϕ^4$ model) is studied by Monte Carlo (MC) simulations and by analytical methods. The model allows to choose a single dimensionless parameter a determining completely the behaviour of the system. Changing a from 0 to $+\infty$ allows to go continuously from the displacive to the order-disorder limit. We calculate the transition temperature $T_c$ and the temperature dependence of the order parameter down to T=0 for a wide range of the parameter a. The $T_c$ from MC calculations shows an excellent agreement with the known asymptotic values for small and large a. The obtained MC results are further compared with predictions of the mean-field and independent-mode approximations as well as with predictions of our own approximation scheme. In this approximation, we introduce an auxiliary system, which yields approximately the same temperature behaviour of the order parameter, but allows the decoupling of the phonon modes. Our approximation gives the value of $T_c$ within an error of 5% and satisfactorily describes the temperature dependence of the order parameter for all values of a.

Massive star evolution revealed in the Mass-Luminosity plane

Year: 2018
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: Massive star evolution is dominated by key physical processes such as mass loss, convection and rotation, yet these effects are poorly constrained, even on the main sequence. We utilise a detached, eclipsing binary HD166734 as a testbed for single star evolution to calibrate new MESA stellar evolution grids. We introduce a novel method of comparing theoretical models with observations in the 'Mass-Luminosity Plane', as an equivalent to the HRD (see Higgins & Vink, 2018). We reproduce stellar parameters and abundances of HD166734 with enhanced overshooting (alpha=0.5), mass loss and rotational mixing. When comparing the constraints of our testbed to the systematic grid of models we find that a higher value of alpha = 0.5 (rather than 0.1) results in a solution which is more likely to evolve to a neutron star than a black hole, due to a lower value of the compactness parameter.
SO(3) vortices as a mechanism for generating a mass gap in the 2d SU(2) principal chiral model

description: We propose a mechanism that can create a mass gap in the SU(2) chiral spin model at arbitrarily small temperatures. We give a sufficient condition for the mass gap to be non-zero in terms of the behaviour of an external Z(2) flux introduced by twisted boundary conditions. This condition in turn is transformed into an effective dual Ising model with an external magnetic field generated by SO(3) vortices. We show that having a nonzero magnetic field in the effective Ising model is sufficient for the SU(2) system to have a mass gap. We also show that certain vortex correlation inequalities, if satisfied, would imply a nonzero effective magnetic field. Finally we give some plausibility arguments and Monte Carlo evidence for the required correlation inequalities.

description: This PhD thesis is part of the project “Antibiotic Resistance Dynamic: the influence of geographic origin and management systems on resistance gene flows within humans, animals and the environment (ARDIG)”, which is part of the “One Health European Joint Programme”. My part is carried out at the German Federal Institute for Risk Assessment in the unit for Epidemiology, Zoonoses and Antimicrobial Resistance. ARDIG will investigate the epidemiology and ecology of antimicrobial resistance in a one health approach combining data from medical and veterinary research. The aim of the PhD thesis is the investigation of antibiotic resistance dynamics and the detailed characterization of antimicrobial resistances in commensal E. coli. Thereby, a focus is set on substances of the (fluoro)quinolone group and the last resort antibiotic colistin. These antimicrobial agents can be used in human and veterinary medicine to combat bacteria involved in a variety of infectious diseases. This also includes zoonotic bacteria, such as E. coli, which is found in animals and food. Resistance to (fluoro)quinolones and colistin can be based either on chromosomal mutations in specific target genes or on plasmid-mediated resistance genes. The occurrence and spread of microorganisms, resistant to these antimicrobial agents can hamper the treatment of some diseases and therefore poses a serious risk to public health. Research for a better understanding of the transmission and dissemination of resistance determinants, including the mobile genetic elements involved, in a one health approach is therefore an important area in zoonoses research.

description: We consider the entanglement Hamiltonian for an interval in a chain of free fermions in its ground state and show that the lattice expression goes over into the conformal one if one includes the hopping to distant neighbours in the continuum limit. For an infinite chain, this can be done analytically for arbitrary fillings and is shown to be the consequence of the particular structure of the entanglement Hamiltonian, while for finite rings or temperatures the result is based on numerical calculations.

Moreover, going over to a modified star-product on $C^{n+1} \setminus \{ 0 \}$, obtained by an equivalence transformation, this description can be even further simplified, allowing the explicit computation of a closed formula for the star-product on $\CP^n$ which can easily transferred to the domain $SU(n+1)/S(U(1)\times U(n))$.

description: Cold clouds in hot media are quickly crushed, shredded, and then accelerated as a result of their interaction with the background gas. The persistence of cold clouds moving at substantial velocities in harsh environments is a common yet puzzling feature of many astrophysical systems, from quasar absorption lines probing galactic halos to clouds of dust passing near Sgr $A^*$. Here we run a set of idealized numerical experiments, subjecting a line of cold clouds at a series of mutual separations to a hot background wind. We find that this stream of clouds is able to shield itself from hydrodynamic destruction by accelerating the hot background material, creating a protective layer of co-moving gas. We write down a simple diffusion equation that reproduces the behavior of the simulations, and we discuss the implications for cosmological gas accretion and G2.

description: We show how, upon heating the spin degrees of freedom of the Hubbard model to infinite temperature, the symmetries of the system allow the creation of steady-states with long-range correlations between $η$-pairs. With induce this heating with either dissipation or periodic driving and evolve the system towards a nonequilibrium steady state, a process which melts all spin order in the system. The steady state is identical in both cases and displays distance-invariant off-diagonal $η$-correlations. These correlations were first recognised in the superconducting eigenstates in Yang's seminal paper [Phys. Rev. Lett 63, 2144 (1989)], which are a subset of our steady states. We show that our results are a consequence of symmetry properties and entirely independent of the microscopic details of the model and the heating mechanism.

The possibility of using the dependence of the tunneling conductance on voltage and temperature to determine the temperature-dependent electron-electron scattering rate at the Fermi energy is discussed. The finite electronic lifetime produced by electron-electron interactions is calculated as a function of temperature for quasiparticles near the Fermi circle. Vertex corrections to the random phase approximation substantially increase the electronic scattering rate. Our results are in an excellent quantitative agreement with experiment.

description: Questions: Quinolones are important antibiotics that can be chromosomally encoded or plasmid-mediated (PMQR). One PMQR mechanism is mediated by Qnr proteins. The horizontal gene transfer of this plasmid-mediated quinolone resistance increases the threat of fallible treatment with some antibiotics. To better understand the qnr PMQR pathway as well as the distribution of qnr genes, Escherichia (E.) coli isolates recovered in 2016 and 2017 from livestock and food were phenotypically and genotypically characterized. Materials & Methods: 6,817 E. coli isolates from the German National Reference Laboratory for Antimicrobial Resistance were investigated. The isolates were received in the German national monitoring program for antimicrobial resistance in zoonotic bacteria, recovered from livestock and food. Antimicrobial resistance was determined by broth microdilution according to CLSI guidelines. MIC values were evaluated using EUCAST epidemiological cut-off values. E. coli resistant to quinolones were subjected to qnr-PCR, XbaI-PFGE, S1-PFGE, WGS and bioinformatic analysis. Six different qnr-PCRs were conducted to identify the respective qnr-variants. Results: Of 6,817 E. coli tested, more than 800 isolates were classified as quinolone-resistant (MICNAL ≥16 mg/L and/or MICCIP ≥0.06 mg/L). The most abundant qnr-variant was qnrS. With the exception of qnrD, other qnr-variants were found evenly distributed within the investigated matrices. In general, E. coli isolates with qnr-genes were found more frequently in the feces of animals than in the meat of the same animal species. PFGE with XbaI-digestion was performed to examine genetic relatedness of isolates. PFGE profiling demonstrated a rather high heterogeneity. The highly diverse PFGE pattern indicates that the screened isolates are not associated to a predominant E. coli clone spreading via vertical transmission. S1-PFGE plasmid profiling showed a variety of extrachromosomal elements of various sizes. Isolates, selected according their XbaI- and S1-PFGE pattern were further screened for their genetic setting through short read whole genome sequencing (WGS). Sequencing of those isolates confirmed the high genetic diversity of the quinolone-resistant E. coli strains. Conclusion: Quinolone-resistance could not be attributed to a specific lineage of E. coli. Further analysis is needed for better understanding of the plasmid diversity within qnr-harboring E. coli and the prerequisites of their spread.

description: We present spatially resolved Chandra narrow-band imaging and imaging spectroscopy of NGC 3393. This galaxy hosts a Compton-thick Seyfert 2 AGN with sub-kpc bipolar outflows that are strongly interacting with the circumnuclear gas. We identify narrow-band excess emission associated with the Ne IX 0.905 keV transition (with likely contributions due to intermediate-state iron emission) that points to strong shocks driven by AGN feedback. Imaging spectroscopy resolves outflow-ISM interaction sites and the surrounding ISM at ~100 pc scales, and suggests the presence of a hot AGN wind above the plane at radii beyond the shock sites. The cross-cone shows evidence for reprocessing of photoionization which has passed through gaps in the torus, and also for collisionally excited plasma which may be powered by a shock-confined equatorial outflow. Deep X-ray observations at sub-arcsecond resolution (such as may be performed very efficiently by Lynx, which would also energetically resolve the complex line emission) are necessary to eliminate model degeneracies and reduce uncertainties in local feedback properties.

description: LSQR and its mathematically equivalent CGLS have been popularly used over the decades for large-scale linear discrete ill-posed problems, where the iteration number $k$ plays the role of the regularization parameter. It has been long known that if the Ritz values in LSQR converge to the large singular values of $A$ in natural order until its semi-convergence then LSQR must have the same the regularization ability as the truncated singular value decomposition (TSVD) method and can compute a 2-norm filtering best possible regularized solution. However, hitherto there has been no definitive rigorous result on the approximation behavior of the Ritz values in the context of ill-posed problems. In this paper, for severely, moderately and mildly ill-posed problems, we give accurate solutions of the two closely related fundamental and highly challenging problems on the regularization of LSQR: (i) How accurate are the low rank approximations generated by Lanczos bidiagonalization? (ii) Whether or not the Ritz values involved in LSQR approximate the large singular values of $A$ in natural order? We also show how to judge the accuracy of low rank approximations reliably during computation without extra cost. Numerical experiments confirm our results.

description: We calculate the local density of states (LDOS) of a superconductor-normal metal sandwich at arbitrary impurity concentration. The presence of the superconductor induces a gap in the normal metal spectrum that is proportional to the inverse of the elastic mean free path $l$ for rather clean systems. For a mean free path much shorter than the thickness of the normal metal, we find a gap size proportional to $l$ that approaches the behavior predicted by the Usadel equation (diffusive limit).

description: We explore charged-Higgs CP-violating effects in an intriguing two-Higgs doublet model which accords special status to the top quark. In this model the heaviness of the top quark originates naturally from the much larger VEV of the second Higgs doublet compared to that of the first. The phenomenology of this model is quite distinct from that of the usual formulations of the two-Higgs doublet model. In particular, the model can easily account for the observed CP violation in the kaon sector even if the CKM matrix is real. The associated non-standard CP phase can be monitored through measurements of the time-dependent CP asymmetry in B to psi K_S in experiments at the upcoming B-factories.

Comparison of Plasmid-Mediated Quinolone Resistance in Escherichia coli Isolates from Livestock and Food in Germany

description: drugs. Resistance to quinolones can be chromosomally encoded or plasmid-mediated (PMQR). One PMQR mechanism is mediated by Qnr proteins. The horizontal gene transfer of this plasmid-mediated quinolone resistance increases the threat of fallible treatment with some antibiotics. To better understand the qnr PMQR pathway as well as the distribution of qnr genes, Escherichia (E.) coli isolates recovered in 2016 and 2017 from livestock and food were phenotypically and genotypically characterized. Materials/methods: 6,817 E. coli isolates from the German National Reference Laboratory for Antimicrobial Resistance were investigated. The isolates were received in the German national monitoring program for antimicrobial resistance in zoonotic bacteria, recovered from livestock and food. Antimicrobial resistance was determined by broth microdilution according to CLSI guidelines. MIC values were evaluated using EUCAST epidemiological cut-off values. E. coli resistant to quinolones were subjected to qnr-PCR, XbaI-PFGE, S1-PFGE, WGS and bioinformatic analysis. Six different qnr-PCRs were conducted to identify the respective qnr-variants. Results: Of 6,817 E. coli tested, more than 800 isolates were classified as quinolone-resistant (MICNAL ≥16 mg/L and/or MICCIP ≥0.06 mg/L). The most abundant qnr-variant was qnrS. With the exception of qnrD, other qnr-variants were found evenly distributed. In general, E. coli isolates with qnr-genes were found more frequently in the feces of animals than in the meat of the same animal species. PFGE with XbaI-digestion was performed to examine genetic relatedness of isolates. PFGE profiling demonstrated a rather high heterogeneity. The highly diverse PFGE pattern indicates that the screened isolates are not associated to a predominant E. coli clone spreading via vertical transmission. S1-PFGE plasmid profiling showed a variety of extrachromosomal elements of various sizes. Isolates, selected according their PFGE pattern were further screened for their genetic setting through short read whole genome sequencing (WGS). Sequencing of those isolates confirmed the high genetic diversity of the quinolone-resistant E. coli strains. Conclusions: Quinolone-resistance could not be attributed to a specific lineage of E. coli. Further analysis is needed for better understanding of the plasmid diversity within qnr-harboring E. coli and the prerequisites of their spread.

description: The cross section of $e^+e^- \to b \bar{b} u \bar{d} μ^- \barν_μ$ process with a complete set of tree diagrams, 232 diagrams in the unitary gauge, was calculated at the energy range of $\sqrt{s}$ = 340 - 500 GeV by using GRACE system. A main contribution to the cross section comes from $t\bar{t}$ production, where $t$ and $\bar{t}$ decay into $bu\bar{d}$ and $\bar{b} μ^- \barν_μ$, respectively. It was found that the interference between the diagrams with $t\bar{t}$ production and those with single-$t$ through $ WW $ pair production amounts to 10% at the $t \bar{t}$ threshold energy region. In the energy region above twice of the top quark mass, more than 95% of the cross section comes from the $t\bar{t}$ diagrams.

description: We present new 0.6-10 GHz observations of the binary neutron star merger GW170817 covering the period up to 300 days post-merger, taken with the Karl G. Jansky Very Large Array, the Australia Telescope Compact Array, the Giant Metrewave Radio Telescope and the MeerKAT telescope. We use these data to precisely characterize the decay phase of the late-time radio light curve. We find that the temporal decay is consistent with a power-law slope of t^-2.2, and that the transition between the power-law rise and decay is relatively sharp. Such a slope cannot be produced by a quasi-isotropic (cocoon-dominated) outflow, but is instead the classic signature of a relativistic jet. This provides strong observational evidence that GW170817 produced a successful jet, and directly demonstrates the link between binary neutron star mergers and short-hard GRBs. Using simple analytical arguments, we derive constraints on the geometry and the jet opening angle of GW170817. These results are consistent with those from our companion Very Long Baseline Interferometry (VLBI) paper, reporting superluminal motion in GW170817.

description: A regularization scheme that explicitly separates vacuum contributions from medium effects is applied to a Nambu--Jona-Lasinio model with diquark interactions and in $β-$equilibrium. We perform a comparison of this proposed scheme with the more traditional one, where no separation of vacuum and medium effects is done. Our results point to both qualitative and quantitative important differences between these two methods, in special regarding the phase structure of the model in the cold and dense nuclear matter case.

description: In the quantum Hall regime, electronic correlations in double-layer two-dimensional electron systems are strong because the kinetic energy is quenched by Landau quantization. In this article we point out that these correlations are reflected in the way the partitioning of charge between the two-layers responds to a bias potential. We report on illustrative calculations based on an unrestricted Hartree-Fock approximation which allows for spontaneous inter-layer phase coherence. The possibility of studying inter-layer correlations by capacitive coupling to separately contacted two-dimensional layers is discussed in detail.
