description: We apply the self-consistent renormalized perturbation theory to the Hubbard model on the square lattice, at finite temperatures in order to study the evolution of the Fermi-surface (FS) as a function of temperature and doping. Previously, a nematic phase for the same model has been reported to appear at weak coupling near a Lifshitz transition from closed to open FS at zero temperature where the self-consistent renormalized perturbation theory was shown to be sensitive to small deformations of the FS. We find that the competition with the superconducting order leads to a maximal nematic order appearing at non-zero temperature. We explicitly observe the two competing phases near the onset of nematic instability and, by comparing the grand canonical potentials, we find that the transitions are first-order. We explain the origin of the interaction-driven spontaneous symmetry breaking to a nematic phase in a system with several symmetry-related Van Hove points and discuss the required conditions.

description: The decay of scalar variance in isotropic turbulence in a bounded domain is investigated. Extending the study of Touil, Bertoglio and Shao (2002; Journal of Turbulence, 03, 49) to the case of a passive scalar, the effect of the finite size of the domain on the lengthscales of turbulent eddies and scalar structures is studied by truncating the infrared range of the wavenumber spectra. Analytical arguments based on a simple model for the spectral distributions show that the decay exponent for the variance of scalar fluctuations is proportional to the ratio of the Kolmogorov constant to the Corrsin-Obukhov constant. This result is verified by closure calculations in which the Corrsin-Obukhov constant is artificially varied. Large-eddy simulations provide support to the results and give an estimation of the value of the decay exponent and of the scalar to velocity time scale ratio.

description: Abstract Alexander von Humboldt repeatedly evaluated Leibniz’ scientifi c achievements and projects. He was especially interested in his contributions to the investigation of earth magnetism and in his writings on earth history and in his invention of the differential calculus. Hence the paper deals with these three subjects. It explains their historical background before it explains Humboldt’s comments and evaluations. To that end some historical documents or letters are published for the first time, in particular Theodor Wittstein’s letter to Humboldt dating from 1851. Zusammenfassung Alexander von Humboldt bewertete wiederholt Leibnizens wissenschaftliche Errungenschaften und Projekte. Insbesondere war er an dessen Beiträgen zur Erforschung des Erdmagnetismus, an dessen Schriften über die Erdgeschichte und an dessen Erfi ndung der Differentialrechnung interessiert. Der Aufsatz beschäftigt sich mit diesen drei Themen. Er erklärt deren historischen Hintergrund, bevor er Humboldts Kommentare und Bewertungen darlegt. Zu diesem Zweck werden einige historische Dokumente oder Briefe zum ersten Mal veröffentlicht, vor allem Theodor Wittsteins Brief an Humboldt aus dem Jahre 1851. Résumé Alexander von Humboldt a évalué à maintes reprises les accomplissements scientifi ques et projets de Leibniz. En particulier, il s’intéressait à ses contributions à la recherche du magnétisme terrestre, à ses écrits sur l’histoire de la terre et à son invention du calcul différentiel. L’article s’occupe de ces trois sujets. Il explique leur contexte historique avant qu’il décrive les commentaires et les évaluations de Humboldt. À cette fi n, quelques documents historiques ou lettres sont publiés pour la première fois, avant tout la lettre de Theodor Wittstein à Humboldt de l’année 1851.

description: We report new mid-infrared observations of the remarkable object IRAS 15099-5856 using the space telescopes AKARI and Spitzer, which demonstrate the presence of prominent crystalline silicate emission in this bright source. IRAS 15099-5856 has a complex morphology with a bright central compact source (IRS1) surrounded by knots, spurs, and several extended (~4') arc-like filaments. The source is seen only at >= 10 um. The Spitzer MIR spectrum of IRS1 shows prominent emission features from Mg-rich crystalline silicates, strong [Ne II] 12.81 um and several other faint ionic lines. We model the MIR spectrum as thermal emission from dust and compare with the Herbig Be star HD 100546 and the luminous blue variable R71, which show very similar MIR spectra. Molecular line observations reveal two molecular clouds around the source, but no associated dense molecular cores. We suggest that IRS1 is heated by UV radiation from the adjacent O star Muzzio 10 and that its crystalline silicates most likely originated in a mass outflow from the progenitor of the supernova remnant (SNR) MSH 15-52. IRS1, which is embedded in the SNR, could have been shielded from the SN blast wave if the progenitor was in a close binary system with Muzzio 10. If MSH15-52 is a remnant of Type Ib/c supernova (SN Ib/c), as has been previously proposed, this would confirm the binary model for SN Ib/c. IRS1 and the associated structures may be the relics of massive star death, as shaped by the supernova explosion, the pulsar wind and the intense ionizing radiation of the embedded O star.

Nonuniform but highly preferential stemflow routing along bark surfaces and actual smaller infiltration areas than previously assumed: A case study on European beech (Fagus sylvatica L.) and sycamore maple (Acer pseudoplatanus L.).

description: Canopy and tree morphology are assumed to play a significant role in modulating the amount of rainfall water during its routing throughout the vegetation and the near‐surface Critical Zone. One crucial point of research addresses the spatial extent of stemflow (SF) infiltration, because its concentration over small areas at the trunk base appears to affect the magnitude and timing of water and solutes input to the soil and hence amplify biogeochemical cycling. By a Brilliant Blue tracer experiment, we examined the flow patterns of SF water along the trunk surface of two broadleaved tree species (Fagus sylvatica and Acer pseudoplatanus) and the infiltration area at the trunk base and down to 0.12‐m soil depth following natural rainfall events. Our results point to highly preferential SF with smaller washed‐off stem areas for sycamore maple (≤15%) compared with European beech (≤39%). The infiltration area is remarkably smaller than the basal area (BA), accounting for only 17% of the BA for beech and for 30% for maple. Differences in decolourized stem areas between the trees do not relate to the magnitude of infiltration areas at the soil surface, suggesting a strong effect of coarse root abundance and run‐off properties on the funnelling of SF water. In essence, our investigation exhibited that SF routing along bark surfaces and infiltration at the trunk base were spatially more concentrated than commonly assumed. The outcome of this study might contribute to our understanding on hydrological and biogeochemical interlinkages between the plant cover and the near‐surface Critical Zone.

description: The vertical structure of debris disks provides clues about their dynamical evolution and the collision rate of the unseen planetesimals. Thanks to the ever-increasing angular resolution of contemporary instruments and facilities, we are beginning to constrain the scale height of a handful of debris disks, either at near-infrared or millimeter wavelengths. Nonetheless, this is often done for individual targets only. We present here the geometric modeling of eight disks close to edge-on, all observed with the same instrument (SPHERE) and using the same mode (dual-beam polarimetric imaging). Motivated by the presence of CO gas in two out of the eight disks, we then investigate the impact that gas can have on the scale height by performing N-body simulations including gas drag and collisions. We show that gas can quickly alter the dynamics of particles (both in the radial and vertical directions), otherwise governed by gravity and radiation pressure. We find that, in the presence of gas, particles smaller than a few tens of microns can efficiently settle toward the midplane at the same time as they migrate outward beyond the birth ring. For second generation gas ($M_\mathrm{gas} \leq 0.1$ $M_\oplus$), the vertical settling should be best observed in scattered light images compared to observations at millimeter wavelengths. But if the gas has a primordial origin ($M_\mathrm{gas} \geq 1$ $M_\oplus$), the disk will appear very flat both at near-infrared and sub-mm wavelengths. Finally, far beyond the birth ring, our results suggest that the surface brightness profile can be as shallow as $\sim -2.25$.

description: Organic amendments are important to sustain soil organic matter (SOM) and soil functions in agricultural soils. Information about the contribution of organic amendments to SOM can be derived from incubation experiments. In this study, data from 72 incubated organic amendments including plant residues, digestates and manure were analysed. The incubation data was compiled from three experimental setups with varying incubation times, soils and incubation temperatures, in which CO2 release was measured continuously. The analysis of the incubation data was performed with an approach relying on conceptual parts of C‐TOOL, CCB, Century, ICBM, RothC and Yasso which are all well‐approved first‐order carbon models that differ in structure and abstraction level. All models are an approximation of reality, whereby each model differs in understanding of the processes involved in soil carbon dynamics. To accumulate the advantages from each model a model ensemble was performed for each substrate. With the ability of each carbon model to compute the distribution of carbon into specific SOM pools a new approach for evaluating organic amendments in terms of humus building efficiency is presented that, depends on the weighted model fit of each ensemble member. Depending on the organic substrate added to the soil, the time course of CO2 release in the incubation studies was predicted with different accuracy by the individual model concepts. Averaging the output of the individual models leads to more robust prediction of SOM dynamics. The EHUM value is easy to interpret and the results are in accordance with the literature.

description: Luminous red galaxies (LRGs) are much rarer and more massive than L* galaxies. Coupled with their extreme colours, LRGs therefore provide a demanding testing ground for the physics of massive galaxy formation. We present the first self-consistent predictions for the abundance and properties of LRGs in hierarchical structure formation models. We test two published models which use quite different mechanisms to suppress the formation of massive galaxies: the Bower et al. (2006) model, which invokes ``AGN-feedback'' to prevent gas from cooling in massive haloes, and the Baugh et al. (2005) model which relies upon a ``superwind'' to eject gas before it is turned into stars. Without adjusting any parameters, the Bower et al. model gives an excellent match to the observed luminosity function of LRGs in the SDSS (with a median redshift of z=0.24) and to their clustering; the Baugh et al. model is less successful in these respects. Both models fail to match the observed abundance of LRGs at z=0.5 to better than a factor of ~2. In the models, LRGs are typically bulge dominated systems with M* of ~2x10^11 h^{-1} M_sun and velocity dispersions of ~250 km s^{-1}. Around half of the stellar mass in the model LRGs is already formed by z~2.2 and is assembled into one main progenitor by z~1.5; on average, only 25% of the mass of the main progenitor is added after z~1. LRGs are predicted to be found in a wide range of halo masses, a conclusion which relies on properly taking into account the scatter in the formation histories of haloes. Remarkably, we find that the correlation function of LRGs is predicted to be a power law down to small pair separations, in excellent agreement with observational estimates. Neither the Bower et al. nor the Baugh et al. model is able to reproduce the observed radii of LRGs.

description: The excitation of an autoionizing resonance by intense radiation requires a theoretical description beyond the transition probability per unit time. This implies a time-dependent formulation incorporating all features of the radiation source, such as pulse temporal shape and duration, as well as stochastic properties, for pulses other than Fourier limited. The radiation from short wavelength free electron lasers is a case in point, as it is the only source that can provide the necessary intensity. In view of ongoing experiments with such sources, we present a systematic study for an isolated autoionizing resonance. We find that intensity, pulse duration and field fluctuations conspire in producing unexpected excitation profiles, not amenable to a description in terms of the usual Fano profile. In particular, the role of intensity fluctuations turns out to pose challenging theoretical problems part of which have been addressed herein.

Abstract This article takes the upcoming 65th birthday of Ottmar Ette as an occasion for a contrastive reading of central lines of research in Ette’s work in relation to Humboldt’s research program. In doing so, it becomes apparent that Ette’s examination of the life and work of the “nomadic” (Ette) explorer Alexander von Humboldt, which began in 1988 and has meanwhile spanned fi ve decades, has not only had a groundbreaking infl uence on the fi eld of international Humboldt research, but that, conversely, there are also clear traces of Humboldtian thought in Ette’s work. Resumen Este artículo aprovecha el próximo 65º aniversario de Ottmar Ette para realizar una lectura contrastada de las líneas centrales de la obra de Ette en relación con el programa de investigación de Humboldt. Al hacerlo, se pone de manifi esto que el examen de Ette de la vida y la obra del explorador “nómada” (Ette) Alexander von Humboldt, que se inició en 1988 y que entretanto ha abarcado cinco décadas, no sólo ha tenido una infl uencia innovadora en el campo de la investigación humboldtiana internacional, sino que, a la inversa, también hay claras huellas del pensamiento humboldtiano en la obra de Ette.

description: Grid-based modelling is widely used for estimating stellar parameters. However, stellar model grid is sparse because of the computational cost. This paper demonstrates an application of a machine-learning algorithm using the Gaussian Process (GP) Regression that turns a sparse model grid onto a continuous function. We train GP models to map five fundamental inputs (mass, equivalent evolutionary phase, initial metallicity, initial helium fraction, and the mixing-length parameter) to observable outputs (effective temperature, surface gravity, radius, surface metallicity, and stellar age). We test the GP predictions for the five outputs using off-grid stellar models and find no obvious systematic offsets, indicating good accuracy in predictions.As a further validation, we apply these GP models to characterise 1,000 fake stars. Inferred masses and ages determined with GP models well recover true values within one standard deviation. An important consequence of using GP-based interpolation is that stellar ages are more precise than those estimated with the original sparse grid because of the full sampling of fundamental inputs.

Magnetic fields and the dynamics of spiral galaxies

Year: 2007
Subjects: subject: Astrophysics (astro-ph)

description: We investigate the dynamics of magnetic fields in spiral galaxies by performing 3D MHD simulations of galactic discs subject to a spiral potential. Recent hydrodynamic simulations have demonstrated the formation of inter-arm spurs as well as spiral arm molecular clouds provided the ISM model includes a cold HI phase. We find that the main effect of adding a magnetic field to these calculations is to inhibit the formation of structure in the disc. However, provided a cold phase is included, spurs and spiral arm clumps are still present if $β\gtrsim 0.1$ in the cold gas. A caveat to two phase calculations though is that by assuming a uniform initial distribution, $β\gtrsim 10$ in the warm gas, emphasizing that models with more consistent initial conditions and thermodynamics are required. Our simulations with only warm gas do not show such structure, irrespective of the magnetic field strength. Furthermore, we find that the introduction of a cold HI phase naturally produces the observed degree of disorder in the magnetic field, which is again absent from simulations using only warm gas. Whilst the global magnetic field follows the large scale gas flow, the magnetic field also contains a substantial random component that is produced by the velocity dispersion induced in the cold gas during the passage through a spiral shock. Without any cold gas, the magnetic field in the warm phase remains relatively well ordered apart from becoming compressed in the spiral shocks. Our results provide a natural explanation for the observed high proportions of disordered magnetic field in spiral galaxies and we thus predict that the relative strengths of the random and ordered components of the magnetic field observed in spiral galaxies will depend on the dynamics of spiral shocks.

description: We study the attractor equations for a quantum corrected prepotential F=t^3+iλ, with λ\in R,which is the only correction which preserves the axion shift symmetry and modifies the geometry. By performing computations in the ``magnetic'' charge configuration, we find evidence for interesting phenomena (absent in the classical limit of vanishing λ). For a certain range of the quantum parameter λwe find a ``separation'' of attractors, i.e. the existence of multiple solutions to the Attractor Equations for fixed supporting charge configuration. Furthermore, we find that, away from the classical limit, a ``transmutation'' of the supersymmetry-preserving features of the attractors takes place when λreaches a particular critical value.

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: Using a three-component, multi-scale diffusion model, we show that the cosmic-ray (CR) proton and helium spectra and the dipole anisotropy can be explained with reasonable parameters. The model includes a nearby source associated with the supernova remnant (SNR) that gave rise to the Geminga pulsar, a source at the Galactic center, and a component associated with the Galactic disk. The CR flux below TeV is dominated by the disk component. The center source with a continuous injection of CRs starting about 18 Myr ago is needed to explain the anisotropy above 100 TeV. With the assumption of universal CR spectra injected by all SNRs, the nearby source can produce a TeV spectral bump observed at Earth via slow diffusion across the interstellar magnetic field, which needs to have an angle $ θ\approx 5^{\circ} $ between the field line and the line of sight toward the source, and have weak magnetic turbulence with the Alfvén Mach number $ M_{\text{A}}\approx 0.1 $. Considering the modulation of the Galactic-scale anisotropy by this magnetic field, in a quasi-local approach the field may be directed at a right ascension about $ -90^{\circ} $ and a declination about $ -7.4^{\circ} $ in the equatorial coordinate system.

The velocity interval of associated metal lines extends for 700 km/s. In addition, saturated H I absorption is detected in the blue damping wing of the main component. The column density ratios of associated Al II, Al III, and Fe II lines indicate that the absorbing material is ionized. 19 of in total 31 detected metal line components are formed within peripheral H II regions, while only 12 components are associated with the predominantly neutral main absorber. For the main absorber the observed abundance ratios of refractory elements to Zn range from Galactic warm disk [Si/Zn] = - 0.40, [Fe/Zn] = -1.10 to halo-like and essentially undepleted patterns. The dust-corrected metal abundances indicate a nucleosynthetic odd-even effect and might imply an anomalous depletion of Si relative to Fe for two components, but otherwise do correspond to solar ratios. The intrinsic average metallicity is almost solar [Fe/H] = -0.08, whereas the uncorrected average is [Zn/H] = -0.38. The ion abundances in the periphery conform with solar element composition. The detection of H II as well as the large variation in dust depletion for this sight line raises the question whether in future studies of damped Ly alpha systems ionization and depletion effects have to be considered in further detail. Ionization effects, for instance, may pretend an enrichment of alpha elements. An empirical recipe for detecting H II regions is provided.

description: Serpentinization environments are key locations that support microbial communities by the abiogenic formation of reduced species associated with peridotite alteration. Here we studied partially serpentinized peridotites from the Chimaera seeps (Turkey), an active continental serpentinization system that vents highly methane‐rich fluids, to investigate the impact of water‐rock interaction on the sulfide and metal mineralogy and its implications on supporting microbial communities. Using high‐resolution scanning electron microscopy, electron microprobe analysis, and transmission electron microscopy we found diverse pentlandite decomposition features with precipitation of secondary sulfides including millerite, heazlewoodite, as well as Cu‐bearing sulfides, native Cu, and awaruite (Ni3Fe). Awaruite forms dense veinlets to single crystal platelets tens of nanometers in size, which is formed by desulphurization of pentlandite. In addition, the nanometer‐sized awaruite platelets are intimately intergrown with serpentine suggesting its growth during peridotite alteration by a dissolution‐precipitation process, likely associated with the interaction of methane‐ and H2‐rich but highly sulfur‐undersaturated fluids. Based on sulfur isotope signatures we infer a mantle and mid‐ocean ridge origin of the sulfide minerals associated with the first stage of partial serpentinization and awaruite formation. Subsequent and ongoing continental fluid‐rock interaction causes significant sulfide decomposition resulting in the formation of porosity and the release of, amongst others, H2S and Fe. These species may likely provide a source of nutrients for active microbial communities in these comparatively nutrient‐starved, low‐temperature continental serpentinization environments.
description: Key Points: High disequilibrium conditions induce skeletal awaruite growth during continental serpentinization. Pentlandite dissolution creates fluid pathways and nutrients for microbial life. Sulfur isotope compositions document ocean floor and subsequent continental serpentinization processes.

description: Statistical shape models (SSMs) are a popular tool to conduct morphological analysis of anatomical structures which is a crucial step in clinical practices. However, shape representations through SSMs are based on shape coefficients and lack an explicit one-to-one relationship with anatomical measures of clinical relevance. While a shape coefficient embeds a combination of anatomical measures, a formalized approach to find the relationship between them remains elusive in the literature. This limits the use of SSMs to subjective evaluations in clinical practices. We propose a novel SSM controlled by anatomical parameters derived from morphometric analysis. The proposed anatomically parameterized SSM (ANAT-SSM) is based on learning a linear mapping between shape coefficients and selected anatomical parameters. This mapping is learned from a synthetic population generated by the standard SSM. Determining the pseudo-inverse of the mapping allows us to build the ANAT-SSM. We further impose orthogonality constraints to the anatomical parameterization to obtain independent shape variation patterns. The proposed contribution was evaluated on two skeletal databases of femoral and scapular bone shapes using clinically relevant anatomical parameters. Anatomical measures of the synthetically generated shapes exhibited realistic statistics. The learned matrices corroborated well with the obtained statistical relationship, while the two SSMs achieved moderate to excellent performance in predicting anatomical parameters on unseen shapes. This study demonstrates the use of anatomical representation for creating anatomically parameterized SSM and as a result, removes the limited clinical interpretability of standard SSMs. The proposed models could help analyze differences in relevant bone morphometry between populations, and be integrated in patient-specific pre-surgery planning or in-surgery assessment.

description: The Earth is constantly hit by energetic particles originating from galactic sources. The flux of these particles is altered by the magnetized solar wind in the heliosphere and the Earth's magnetic field. For this reason, the ability of a particle to approach a spacecraft in low Earth orbit depends on its energy and the position of the spacecraft within the Earth's magnetosphere. Moreover, there are some areas (radiation belts) where the particles are trapped for a long time and, therefore, the flux of energetic particles is particularly high. Occasionally, solar energetic particles contribute to the energetic particle flux too. DOSimetry TELescope (DOSTEL) is one of the instruments aboard the International Space Station (ISS) that monitors the radiation field within the European module Columbus. Because being installed inside the ISS, particles produced by the interaction between the “primary” radiation and the ISS materials are also measured. To describe the observations in such a complex radiation field, we follow the method by Caballero‐Lopez and Moraal (2012, Journal of Geophysical Research, 117[A12], A12103. doi:10.1029/2012JA017794) to compute the so‐called yield function using precise measurements of the proton and helium energy spectra obtained by alpha magnet spectrometer and the systematic variation of the DOSTEL measurements within the Earth's magnetosphere.

description: Zusammenfassung Während seines Aufenthalts 1803 in Mexiko machte von Humboldt die Bekanntschaft von Dupaix, einem spanischen Soldaten luxemburgischer Herkunft und Liebhaber präkolumbischer Altertümer. Die Entdeckung verschiedener Manuskripte Dupaix’ sowie die Untersuchung diverser Archive und persönlicher Aufzeichnungen des Freiherrn und von Dokumenten unterschiedlicher Institutionen beiderseits des Atlantiks erlauben es, den außergewöhnlichen Weg eines berühmten mexikanischen Objekts, der Chalchiuhtlicue, nachzuvollziehen, die der preußische Forschungsreisende 1810 als „aztekische Priesterin“ in seinem Buch Vues des cordillères … beschrieben hatte. Der vorliegende Beitrag versucht, die verschiedenen Besitzer und die Umstände nachzuzeichnen, welche die Wanderung dieser emblematischen prähispanischen Statuette von Mexiko-Stadt nach London fast ein halbes Jahrhundert lang begleitet haben. Abstract In 1803, during his sojourn in Mexico, von Humboldt made the acquaintance of Dupaix, a Spanish soldier of Luxemburgish origin with a keen interest in pre-Columbian art. The discovery of several manuscripts belonging to Dupaix, together with a study of various archives and personal notes left by Humboldt, not to mention the documents held in different institutions on both sides of the Atlantic, have made it possible to recreate the remarkable itinerary of a famous Mexica work of art, that of Chalchiuhtlicue. In his ground-breaking work Vues des cordillères … published in 1810, the Prussian explorer had referred to her as an “Aztec Priestess”. In this article we attempt to trace the various successive owners of this emblematic pre-Hispanic statuette and the circumstances surrounding the period of almost 50 years it spent wandering between Mexico and London. Resumen El descubrimiento de diferentes manuscritos de Dupaix, militar español de origen luxemburgués afi cionado a las antigüedades precolombinas que se entrevistó en 1803 con von Humboldt con motivo de su estancia en México, unido al examen de diversos archivos y notas personales del barón, así como de documentos conservados en diversas instituciones de uno y otro lado del Atlántico, permite seguir el recorrido singular de una célebre antigüedad mexicana, a saber la Chalchiuhtlicue, que el explorador prusiano identifi có en 1810 como una “sacerdotisa azteca” en su obra Vues des cordillères … La presente contribución intenta rastrear a los sucesivos diferentes propietarios y las circunstancias que han acompañado durante más de medio siglo a la peregrinación de esta emblemática estatuilla prehispánica de México a Londres.

description: A method for the construction of approximate analytical expressions for the stationary marginal densities of general stochastic search processes is proposed. By the marginal densities, regions of the search space that with high probability contain the global optima can be readily defined. The density estimation procedure involves a controlled number of linear operations, with a computational cost per iteration that grows linearly with problem size.
