description: In this paper we present the analytic form of the heavy-quark coefficient functions for deep-inelastic lepton-hadron scattering in the kinematical regime $Q^2 \gg m^2$ . Here $Q^2$ and $m^2$ stand for the masses squared of the virtual photon and heavy quark respectively. The calculations have been performed up to next-to-leading order in the strong coupling constant $α_s$ using operator product expansion techniques. Apart from a check on earlier calculations, which however are only accessible via large computer programs, the asymptotic forms of the coefficient functions are useful for charm production at HERA when the condition $Q^2 \gg m_c^2$ is satisfied. Furthermore the analytical expressions can also be used when one applies the variable heavy flavour scheme up to next-to-leading order in $α_s$.

description: Vacuum polarization and particle production effects in classical electromagnetic and gravitational backgrounds can be studied by the effective lagrangian method. Background field configurations for which the effective lagrangian is zero are special in the sense that the lowest order quantum corrections vanishes for such configurations. We propose here the conjecture that there will be neither particle production nor vacuum polarization in classical field configurations for which all the scalar invariants are zero. We verify this conjecture, by explicitly evaluating the effective lagrangian, for non-trivial electromagnetic and gravitational backgrounds with vanishing scalar invariants. The implications of this result are discussed.

description: Experimental results on amorphous ZrAlCu thin film growth and the dynamics of the surface morphology as predicted from a minimal nonlinear stochastic deposition equation are analysed and compared. Key points of this study are (i) an estimation procedure for coefficients entering into the growth equation and (ii) a detailed analysis and interpretation of the time evolution of the correlation length and the surface roughness. The results corroborate the usefulness of the deposition equation as a tool for studying amorphous growth processes.

description: We consider the effective field theory generated by a heavy mediator that connects Standard Model particles to a Dark Sector, considering explicitly the flavor structure of the operators. In particular, we study the model independent running and mixing between operators, as well as their matching at the electroweak scale. In addition to the explicit expression of the Renormalization Group Equations, we show the numerical solutions as well as some approximate analytical expressions that help understanding these solutions. At low energy, our results are particularly important in the case of light dark sectors communicating to the b quark, and can be immediately applied to flavored Dark Matter.

description: In this paper, we examine a new updated solar model taking advantage of recent reexamination of the nuclear reactions rates and of the microscopic diffusion of helium and heavy elements. Our best model fits the helioseismic data reasonably well: the base of the convective zone is at r=0.715 Ro, the photospheric helium in mass fraction is 0.243 and the sound speed square difference between the Sun and the model is < 1%. This model leads to a reestimate of the neutrinos fluxes : 7.18 SNU for the chlorine experiment, 127.2 SNU for the gallium detector and 4.82 10^6/cm2/s for the B8 neutrino flux. Acoustic and gravity mode predictions are also estimated. We present 3 models which respect the helioseismic constraints and fit the seismic observations better by taking advantage of the known physical uncertainties: nuclear reaction rates, CNO abundances and microscopic diffusion. We conclude that the standard model in side its inherent uncertainties, is robust in the light of the present acoustic mode detection and that the neutrino fluxes prediction is not well constrained.

description: Um Steifigkeitsanpassungen durch Einstiche an Druckkämmen vornehmen zu können, ist es notwendig, eine andere Welle Nabe Verbindung vorzusehen, als den meist genutzten Pressverband. Viel Spielraum bietet hierbei eine Schweißnahtverbindung. Durch die umlaufende Axialkraft auf den Druckkamm, liegt eine hohe Spannungsamplitude im Bereich der Schweißnaht vor. Die metallurgische Kerbe der Schweißnaht und die geometrische Kerbe, die sich aus der Geometrie des Druckkamms ergibt, müssen örtlich getrennt werden. Dieswurde im Verbundvorhaben „TurboGetEff“ mit der PILLER Blowers & Compressors GmbH untersucht.
description: In order to be able to make stiffness adjustments through recesses to thrust cones, it is necessary to provide a shaft-hub connection other than the most commonly used press fit. A welded joint offers many options. Due to the rotating axial force on the thrust cone, there is a high stress amplitude in the area of the welded joint. The metallurgical notch of the weld seam and the geometric notch resulting from the geometry of the thrust cone must be separated locally. This was investigated in the project "TurboGetEff" with PILLER Blowers & Compressors GmbH.

However, the Committee for Spermatophyta (in Taxon 43: 277. 1994) voted heavily against the proposal under the Berlin Code but agreed that the case should be reconsidered under the Tokyo Code. The Committee subsequently (in Taxon 54: 1093. 2005) did not recommend the name for rejection.

Fate of the extended states in a vanishing magnetic field: the role of spins in strongly-interacting 2D electron systems

subject: FOS: Physical sciences

description: In non-interacting or weakly-interacting 2D electron systems, the energy of the extended states increases as the perpendicular magnetic field approaches zero: the extended states "float up" in energy, giving rise to an insulator. However, in those 2D systems where metallic conductivity has been recently observed in zero magnetic field, the energy of the extended states remains constant or even decreases as B -> 0, thus allowing conduction in the limit of zero temperature. Here we show that aligning the electrons' spins causes the extended states to once more "float up" in energy in the vanishing perpendicular magnetic field, as they do for non- or weakly-interacting electrons. The difference between extended states that float up (an insulator) or remain finite (a metal) is thus tied to the existence of the spins.

description: Halo merger trees are constructed from ELUCID, a constrained $N$-body simulation in the Sloan Digital Sky Survey (SDSS) volume. These merger trees are used to populate dark matter halos with galaxies according to an empirical model of galaxy formation. Mock catalogs in the SDSS sky coverage are constructed, which can be used to study the spatial distribution of galaxies in the low-$z$ Universe. These mock catalogs are used to quantify the cosmic variance in the galaxy stellar mass function (GSMF) measured from the SDSS survey. The GSMF estimated from the SDSS magnitude-limited sample can be affected significantly by the presence of the under-dense region at $z<0.03$, so that the low-mass end of the function can be underestimated significantly. Several existing methods designed to deal with the effects of the cosmic variance in the estimate of GSMF are tested, and none is found to be able to fully account for the cosmic variance. We propose a method based on the conditional stellar mass functions in dark matter halos, which can provide an unbiased estimate of the global GSMF. The application of the method to the SDSS data shows that the GSMF has a significant upturn at $M_*< 10^{9.5} h^{-1}{\rm M}_\odot$, which has been missed in many earlier measurements of the local GSMF.

description: We introduce microscopic polarization and magnetization fields at each site of an extended system, as well as free charge and current density fields associated with charge movement from site to site, by employing a lattice gauge approach based on a set of orthogonal orbitals associated with each site. These microscopic fields are defined using a single-particle electron Green function, and the equations governing its evolution under excitation by an electromagnetic field at arbitrary frequency involve the electric and magnetic fields rather than the scalar and vector potentials. If the sites are taken to be far from each other, we recover the limit of isolated atoms. For an infinite crystal we choose the orbitals to be maximally-localized Wannier functions, and in the long wavelength limit we recover the expected linear response of an insulator, including the zero frequency transverse conductivity of a topologically nontrivial insulator. For a topologically trivial insulator we recover the expected expressions for the macroscopic polarization and magnetization in the ground state, and find that the linear response to excitation at arbitrary frequency is described solely by the microscopic polarization and magnetization fields. For very general optical response calculations the microscopic fields necessarily satisfy charge conservation, even under basis truncation, and do not suffer from the false divergences at zero frequency that can plague response calculations using other approaches.

description: Insecticide use and insufficient forage are two of the leading stressors to pollinators in agroecosystems. While these factors have been well studied individually, the experimental designs do not reflect real-world conditions where insecticide exposure and lack of forage occur simultaneously and could interactively suppress pollinator health. Using outdoor enclosures, we tested the effects of insecticides (imidacloprid + lambda-cyhalothrin) and non-crop forage (clover) in a factorial design, measuring the survival, behaviour and performance of bumblebees (Bombus impatiens), as well as pollination of the focal crop, watermelon. Colony survival was synergistically reduced to 17% in watermelon alone + insecticides (survival was 100% in all other treatments). However, behavioural shifts in foraging were mainly due to insecticides (e.g. 95% reduced visitation rate to watermelon flowers), while impacts on hive performance were primarily driven by clover presence (e.g. 374% increase in the number of live eggs). Insecticide-mediated reductions in foraging decreased crop pollination (fruit set) by 32%. Altogether, these data indicate that both insecticides and non-crop forage play integral roles in shaping pollinator health in agricultural landscapes, but the relative importance and interaction of these two factors depend on which aspect of ‘health’ is being considered.

description: We show that one loop GUT scale threshold corrections to gauge couplings are a significant constraint on the GUT symmetry breaking sector of the theory. The one loop threshold corrections relate the prediction for $α_s(M_Z)$ to the proton lifetime. We have calculated these corrections in a new complete SO(10) SUSY GUT. The results are consistent with the low energy measurement of $α_s(M_Z)$. We have also calculated the proton lifetime and branching ratios in this model. We show that proton decay rates provide a powerful test for theories of fermion masses.

description: Ein Tröpferlbad dient als Inspiration für die Frage nach den räumlichen Möglichkeiten eines einfachen Volksbades im innerstädtischen Bestand. Die Gedanken sich mit Menschen im Wasser zu umgeben, reduziert auf das Baden führen über die Geschichte und Kulturen des Badens und der Hygiene hin zu den heutigen Thermen und Erlebnisbädern und der eigentlichen Notwendigkeit eines Volksbades und der Bedeutung dessen im öffentlichen Raum. Ein Wasser für Alle, dass man unkompliziert und auf kurzer Distanz im Stadtgebiet erreichen kann, ist fast nicht mehr auffindbar. Warum nicht auch Bäder die wieder, wie auch die Tröpferlbäder, einfach und unkompliziert genutzt werden können? Keine große Halle, aber doch genug für ein paar Leute, die ein wenig schwimmen wollen, die das Wasser kennenlernen müssen, um die Ecke und nicht weit von daheim, um sich treffen und plaudern, um das Wasser zu fühlen. So wird in der Arbeit anhand eines Bestandshauses in einem der inneren Bezirke Wiens die Möglichkeit zur Schaffung eines öffentlichen Volksbades aufgezeigt, welches sich ganz natürlich in ein bestehendes spätes Jahrhundertwendehaus einfügt. Im Fokus der Arbeit steht die Reduziertheit auf das Wesentliche, der Wertschätzung der Konstruktion und der Möglichkeit einer Transformation. Gewählt wurde ein Gebäude im 8. Bezirk, welches durch die Architekten Karl und Wilhelm Schön im Jahr 1913 geplant und errichtet worden ist. Das alltägliche, gemeinsame im Wasser Sein steht mit der Präsenz der Öffentlichkeit und mit der Intimität des Badens in einem Spannungsverhältnis.

The idea of surrounding oneself with people in water, reduced to bathing, leads via the history and cultures of bathing and hygiene to today`s thermal baths and adventure pools and the actual necessity of a public bath and its importance in public space. It is almost impossible to find water for everyone that can be reached easily and within a short distance in urban areas. Why not also have pools that can be used simply and easily, just like the „Tröpferlbäder”? Not a large hall, but still enough for a few people who want to swim a little, who need to get to know the water, around the corner and not far from home, to meet up and chat, to feel the water. The design utilises an existing building in one of Vienna`s inner districts to demonstrate the possibility of creating a public swimming pool that fits naturally into an existing late turn-of-the-century building. The work focusses on the reduction to the essentials, the appreciation of the construction and the possibility of transformation. A building in the 8th district was chosen, which was planned and built by the architects Karl and Wilhelm Schön in 1913. The everyday, shared experience of being in the water is in tension with the presence of the public and the intimacy of bathing.

description: We present first-principles approaches based on density functional theory for calculating positron states and annihilation characteristics in condensed matter. The treatment of the electron-positron correlation effects (the enhancement of the electron density at the positron with respect to mean-field density) is shown to play a crucial role when calculating the annihilation rates. A generalized gradient approximation (GGA) takes the strong inhomogeneities of the electron density in the ion core region into account and reproduces well the experimental total annihilation rates (inverses of the positron lifetimes) by suppressing the rates given by a local density approximation (LDA). The GGA combined with an electron-state-dependent enhancement scheme gives a good description for the momentum distributions of the annihilating positron-electron pairs reproducing accurately the trends observed in the angular correlation (ACAR) or Doppler broadening measurements of the annihilation radiation. The combination of the present positron lifetime and momentum density calculations with the corresponding measurements yields a unique tool for defect identification. Especially, the investigation of various vacancy-type defects in semiconductors able to trap positrons will be an important field for these methods. We will show that the identification of vacancy-impurity complexes in highly n-Type Si and the study of the SiO$_2$/Si interface are particularly interesting applications.

description: We study the dynamics and timescales of a periodically driven Fermi-Hubbard model in a three-dimensional hexagonal lattice. The evolution of the Floquet many-body state is analyzed by comparing it to an equivalent implementation in undriven systems. The dynamics of double occupancies for the near- and off-resonant driving regime indicate that the effective Hamiltonian picture is valid for several orders of magnitude in modulation time. Furthermore, we show that driving a hexagonal lattice compared to a simple cubic lattice allows to modulate the system up to 1~s, corresponding to hundreds of tunneling times, with only minor atom loss. Here, driving at a frequency close to the interaction energy does not introduce resonant features to the atom loss.

description: While environmental DNA (eDNA) metabarcoding holds promise as a holistic approach to assess vegetation changes and community composition across diverse spatial and temporal scales, systematic investigations of its efficacy compared to conventional field surveys remain scarce in the literature. The present study explores the differences in plant diversity recovered from field surveys and captured with a multi-marker eDNA metabarcoding approach (two nrDNA ITS1 and ITS2, and two cpDNA rbcL and trnL) from river water samples. The eDNA metabarcoding approach retrieved 46 aquatic plants (hydrophytes and helophytes) and 245 terrestrial plants, compared to 24 and 127 species identified from field surveys. On average, eDNA samples collected immediately downstream of the survey sites recovered 43% and 39% of the aquatic and terrestrial species observed, respectively. Discrepancies were explained by differences in taxonomic resolution, the stochasticity of the retrieval of rare and elusive species, and the presence of reference sequences. We found a significant positive correlation between spatial and community distances at scales ranging from 2-9 km and identified turnover as the driving force of these differences. Metabarcoding demonstrated sensitivity to community changes and both approaches converge on a similar community structure. Interestingly, eDNA samples collected immediately upstream of the survey sites exhibited significant species overlap with the downstream samples (c. 100 m apart). Overall our results demonstrate that, with adequate sampling and a multi-marker metabarcoding approach, eDNA has the potential to approximate catchment gamma diversity while still being informative of the local flora.

An alternative approach to the Finger of God in large scale structures

description: It is generally accepted that linear theory of growth of structure under gravity produces a squashed structure in the two-point correlation function (2PCF) along the line of sight (LoS). On the other hand, the observed radial spread out structure known as Finger of God (FoG) is attributed to non-linear effects, like virial relaxation or random motions in the inner regions of galaxy clusters, or non-linear terms in collapse theory. In this paper we argue that the squashed structure associated with the redshift-space ($s-$) linear theory 2PCF is obtained only when this function is displayed in real-space ($r-$), or when the mapping from $r-$ to $s-$space is trivialized by one of a series of approximations: the "wide separation" sometimes mistaken by the "distant observer", the $μ(r) \sim μ(s)$ in the cosine of the position vector with the LoS, or plainly by approximating $s \sim r$. To display the $s-$space 2PCF properly in a grid in $s-$space requires one to solve for the mapping function $\bm s(\bm r)$ and its inverse, which exists in the small gravitational disturbance case. We find this mapping by using plane of the sky projections of the $r-$ and $s-$ 2PCFs in the simplest case of the linear Kaiser spectrum with a conservative power-law $r-$space 2PCF. We show that even in this simple case, a structure quite similar to the FoG is observed in the small scale region, while in the large scale the expected squashed structure is obtained. We show that the observed structure is a function of three parameters: the dimensionless growth rate for visible matter ($β$), the power-law exponent ($γ$) and the cosmological distortion given by the Alcock-Paczy{ń}ski parameter ($AP$). We conclude that there appears to be the way of discerning between cosmological and gravitational redshift distortions avoiding known degeneracies.

Alpha Surfaces for Complex Space-Times with Torsion

description: This paper studies necessary conditions for the existence of alpha-surfaces in complex space-time manifolds with nonvanishing torsion. For these manifolds, Lie brackets of vector fields and spinor Ricci identities contain explicitly the effects of torsion. This leads to an integrability condition for alpha-surfaces which does not involve just the self-dual Weyl spinor, as in complex general relativity, but also the torsion spinor, in a nonlinear way, and its covariant derivative. Interestingly, a particular solution of the integrability condition is given by conformally right-flat and right-torsion-free space-times.

description: Insecticide use and insufficient forage are two of the leading stressors to pollinators in agroecosystems. While these factors have been well studied individually, the experimental designs do not reflect real-world conditions where insecticide exposure and lack of forage occur simultaneously and could interactively suppress pollinator health. Using outdoor enclosures, we tested the effects of insecticides (imidacloprid + lambda-cyhalothrin) and non-crop forage (clover) in a factorial design, measuring the survival, behaviour and performance of bumblebees (Bombus impatiens), as well as pollination of the focal crop, watermelon. Colony survival was synergistically reduced to 17% in watermelon alone + insecticides (survival was 100% in all other treatments). However, behavioural shifts in foraging were mainly due to insecticides (e.g. 95% reduced visitation rate to watermelon flowers), while impacts on hive performance were primarily driven by clover presence (e.g. 374% increase in the number of live eggs). Insecticide-mediated reductions in foraging decreased crop pollination (fruit set) by 32%. Altogether, these data indicate that both insecticides and non-crop forage play integral roles in shaping pollinator health in agricultural landscapes, but the relative importance and interaction of these two factors depend on which aspect of ‘health’ is being considered.

description: The precise reconstruction of jet transverse momenta in heavy-ion collisions is a challenging task. A major obstacle is the large number of (mainly) low-$p_{\rm T}$ particles overlaying the jets. Strong region-to-region fluctuations of this background complicate the jet measurement and lead to significant uncertainties. In this paper, a novel approach to correct jet momenta (or energies) for the underlying background in heavy-ion collisions is introduced. The proposed method makes use of common Machine Learning techniques to estimate the jet transverse momentum based on several parameters, including properties of the jet constituents. Using a toy model and HIJING simulations, the performance of the new method is shown to be superior to the established standard area-based background estimator. The application of the new method to data promises the measurement of jets down to extremely low transverse momenta, unprecedented thus far in data on heavy-ion collisions.
