description: Rayleigh scattering is a result of an interaction of photons with bound electrons. Rayleigh scattering is mostly neglected in calculations of hot star model atmospheres because most of the hydrogen atoms are ionized and the heavier elements have a lower abundance than hydrogen. In atmospheres of some chemically peculiar stars, helium overabundant regions containing singly ionized helium are present and Rayleigh scattering can be a significant opacity source. We evaluate the contribution of Rayleigh scattering by neutral hydrogen and singly ionized helium in the atmospheres of hot stars with solar composition and in the atmospheres of helium overabundant stars. We computed several series of model atmospheres using the TLUSTY code and emergent fluxes using the SYNSPEC code. These models describe atmospheres of main sequence B-type stars with different helium abundance. We used an existing grid of models for atmospheres with solar chemical composition and we calculated an additional grid for helium-rich stars with $N$(He)/$N$(H)=10. Rayleigh scattering by neutral hydrogen can be neglected in atmospheres of hot stars, while Rayleigh scattering by singly ionized helium can be a non-negligible opacity source in some hot stars, especially in helium-rich stars.

description: Böden als endliche und nicht vermehrbare Ressource zählen zu den Lebensgrundlagen des Menschen. Auf Grundlage der gesetzgeberischen Vorgaben sind schädliche Einwirkungen auf das Schutzgut Boden so weit wie möglich zu vermeiden und die Bodenfunktionen nachhaltig zu sichern (BBodSchG 1999). Der nachhaltige Umgang mit der Ressource Boden dient somit der Grunddaseinsfürsorge für heutige und künftige Generationen. Der vorsorgende Bodenschutz ist als gesamtgesellschaftliche Aufgabe zu betrachten und sollten im Rahmen der Stadt- und Regionalplanung deshalb eine stärkere Berücksichtigung erfahren. In der Bundesrepublik Deutschland leben aktuell (2021) knapp mehr als drei Viertel der Bevölkerung in urbanen Räumen (The World Bank o.J.). Vor allem Metropolregionen und wirtschaftsstarken Großstädten mit ihren Umlandgemeinden wird für die Zukunft ein zunehmender Verstädterungsgrad prognostiziert. Geografisch sind die Hauptzentren der Besiedelung vorwiegend in naturräumlich günstigen Senken- und Beckenlandschaften konzentriert, die durch verbreitete Vorkommen von spätpleistozänen kaltzeitlichen Sedimenten (z. B. Löss, periglaziale Deckschichten) im oberflächennahen Untergrund gekennzeichnet sind. Im Holozän entwickelten sich auf den Flächen vielfach qualitativ hochwertige Böden, denen im Rahmen von Bodenfunktionsbewertungen ein überdurchschnittlich hoher Funktionserfüllungsgrad attestiert wird. Der Beitrag beleuchtet die Auswirkungen der raumgreifenden Siedlungsentwicklung in Agglomerationsräumen auf das Schutzgut Boden. Gestützt auf aktuelle Datenerhebungen wird am Beispiel von Frankfurt am Main exemplarisch aufgezeigt, dass die Umwandlung von bestehenden Freiflächen in Siedlungs- und Verkehrsflächen überwiegend zu Lasten von hochertragsfähigen Bodenstandorten ausfällt. Als Folge der Voll- oder Teilversiegelung gehen die vielfältigen Bodenfunktionen verloren und werden dem Landschaftshaushalt damit gänzlich oder teilweise entzogen.
 Darüber hinaus werden die aus dem Flächenverbrauch allgemein erwachsenden Problematiken (z. B. Stadtentwässerung, Stadtklima) in den Kontext einer nachhaltigen Stadtentwicklung gestellt, die darauf abzielt, im Rahmen des vorsorgenden Bodenschutzes kommunale Bodenschutzkonzeptionen zu entwickeln, um die leistungsstärksten Böden zukünftig besser zu schützen und damit auch einen Beitrag zur Klimaanpassung zu leisten.

On the correspondence between Koopman mode decomposition, resolvent mode decomposition, and invariant solutions of the Navier-Stokes equations

description: The relationship between Koopman mode decomposition, resolvent mode decomposition and exact invariant solutions of the Navier-Stokes equations is clarified. The correspondence rests upon the invariance of the system operators under symmetry operations such as spatial translation. The usual interpretation of the Koopman operator is generalised to permit combinations of such operations, in addition to translation in time. This invariance is related to the spectrum of a spatio-temporal Koopman operator, which has a travelling wave interpretation. The relationship leads to a generalisation of dynamic mode decomposition, in which symmetry operations are applied to restrict the dynamic modes to span a subspace subject to those symmetries. The resolvent is interpreted as the mapping between the Koopman modes of the Reynolds stress divergence and the velocity field. It is shown that the singular vectors of the resolvent (the resolvent modes) are the optimal basis in which to express the velocity field Koopman modes where the latter are not a priori known.

Anterior and posterior gonopods of Caprobolus are unique for Spirobolida. Anterior gonopods with a conspicuously enlarged, slender sternite (Fig. 41A), but sternite still much wider than in Spiromimus (Wesener and Enghof, 2009). Telopodite of anterior gonopods prominently enlarged into unique, long, slender, sabre-like processes (Fig. 41B). Basis of telopodite process projecting into a slender, well-rounded retrorse process (Fig. 41B), which is present in numerous genera of Spirobolida. Telopodite of posterior gonopod longer than, but as wide as, coxite (Fig. 41C). Telopodite basally deeply divided into two branches of almost similar width and length (Figs 41 C–E). Sperm canal is free, starting at basis of telopodite, only slightly attached to shorter, lateral main branch (Fig. 41E). Sperm canal projecting as a flagellum above telopodite branches (Fig. 41D). Shares a reddish colour pattern and a yellowish dorsal stripe with Spiromimus de Saussure & Zehntner, 1901, Alluviobolus gen. n. and Ostinobolus gen. n. Gnathochilarium with a subdivided mentum and a single sclerotized ledge on each stipites (Fig. 39E), like in Flagellobolus, Riotintobolus, Pseudocentrobolus, Granitobolus, Alluviobolus gen. n., Ostinobolus gen. n. Distribution and ecology : only known from the rainforests of Andringitra, close by Ivohibe and Vevembe, located at the edge of the high plateau towards the east coast in the southern half of Madagascar (Fig. 30). The only known species of Caprobolus was collected in Andringitra together with a Spiromimus species. Etymology: Caprobolus, masculine, composed of Capro -, formed after capricornus, which refers to the tropic of Capricorn where this genus was first collected, and -bolus.

description: In diesem Beitrag werden detaillierte urbane Oberflächenmodelle und -inventare als wichtige Instrumente für die Planung und Umsetzung von Klimaanpassungsmaßnahmen in urbanen Gebieten vorgestellt. Die nachhaltige und ressourceneffiziente Quartiersentwicklung erfordert eine Analyse des Ausgangszustands, die Formulierung von Zielen sowie die Entwicklung, Auswahl und Umsetzung von Maßnahmen. Der Beitrag zeigt, wie Grundlagen, Hilfsmittel und verallgemeinerungsfähige Beispiele dazu beitragen können, Kommunen bei diesem Prozess zu unterstützen.
 Eine besondere Herausforderung stellt die Erhebung oder Ableitung von Befestigungs- und Versiegelungsarten für urbane Gebiete dar. Amtliche und kommunale Datenbestände erfassen hauptsächlich die Nutzung von Flächen auf Flurstücks- oder Gebäudeebene, wobei die Nutzung zwar auf die Befestigung- oder Oberflächenart hinweist, aber keine eindeutige Klassifizierung zulässt.
 In dem Beitrag werden verschiedene datengetriebene Methoden der Identifizierung von Befestigungs-/Oberflächenarten miteinander verglichen. Unter anderem werden dafür frei verfügbare Laserscanning-, RGBI- und amtliche Katasterdaten genutzt. Die Vorgehensweise wird anhand einer Fallstudie in Köln vorgestellt. Die Vergleiche erfassen die Güte, Stärken, Schwächen, und Kombinationsmöglichkeiten der Methoden und tragen so nützliche Erkenntnisse zur Anwendung bei. Ergebnisse einer Felderhebung in Form einer Biotoptypenkartierung im Fallstudiengebiet werden zur Validierung und Bewertung herangezogen, womit die Vergleiche auf eine objektive Basis gestellt werden.
 Insgesamt zeigt der Beitrag, wie Daten für urbane Oberflächenmodelle und -inventare bei fehlenden Felderhebungen möglichst automatisiert erstellt, aktualisiert oder angereichert werden können. Der Methodenvergleich soll eine objektive Beurteilung der Datenlage und der Möglichkeiten der Datengenerierung darstellen, um kommunale Akteure bei der Analyse der nachhaltigen und ressourceneffizienten Quartiersentwicklung und Klimaanpassungsmaßnahmen zu unterstützen.

description: This thesis is devoted to the study of a nonlinear functional integral equation. First, two sufficient conditions for the existence and some properties of solutions are proved. By using Banach’s fixed point theorem, we have the first sufficient condition yielding existence, uniqueness and stability of the solution. By applying Schauder’s fixed point theorem, we have the second sufficient condition for the existence and compactness of the solution set. Some examples are also given in order to illustrate the results obtained here. Finally, we investigate the quadratic convergence for the solution.

AdS and Lifshitz Scalar Hairy Black Holes in Gauss-Bonnet Gravity

description: We consider Gauss-Bonnet (GB) gravity in general dimensions, which is non-minimally coupled to a scalar field. By choosing the scalar potential of the type $V(ϕ)=2Λ_0+\fft 12m^2ϕ^2+γ_4ϕ^4$, we first obtain large classes of scalar hairy black holes with spherical/hyperbolic/planar topologies that are asymptotic to locally anti-de Sitter (AdS) space-times. We derive the first law of black hole thermodynamics using Wald formalism. In particular, for one class of the solutions, the scalar hair forms a thermodynamic conjugate with the graviton and nontrivially contributes to the thermodynamical first law. We observe that except for one class of the planar black holes, all these solutions are constructed at the critical point of GB gravity where there exists an unique AdS vacua. In fact, Lifshitz vacuum is also allowed at the critical point. We then construct many new classes of neutral and charged Lifshitz black hole solutions for a either minimally or non-minimally coupled scalar and derive the thermodynamical first laws. We also obtain new classes of exact dynamical AdS and Lifshitz solutions which describe radiating white holes. The solutions eventually become an AdS or Lifshitz vacua at late retarded times. However, for one class of the solutions the final state is an AdS space-time with a globally naked singularity.

description: We announce the discovery of the Aquarius~2 dwarf galaxy, a new distant satellite of the Milky Way, detected on the fringes of the VST ATLAS and the SDSS surveys. The object was originally identified as an overdensity of Red Giant Branch stars, but chosen for subsequent follow-up based on the presence of a strong Blue Horizontal Branch, which was also used to measure its distance of $\sim 110$ kpc. Using deeper imaging from the IMACS camera on the 6.5m Baade and spectroscopy with DEIMOS on Keck, we measured the satellite's half-light radius $5.1\pm 0.8$ arcmin, or $\sim 160$ pc at this distance, and its stellar velocity dispersion of $5.4^{+3.4}_{-0.9}$ km s$^{-1}$. With $μ=30.2$ mag arcsec$^{-2}$ and $M_V=-4.36$, the new satellite lies close to two important detection limits: one in surface brightness; and one in luminosity at a given distance, thereby making Aquarius~2 one of the hardest dwarfs to find.

description: A new scheme for enantiomer differentiation of chiral molecules using a pair of linearly polarized intense ultrashort laser pulses with skewed mutual polarization is presented. The technique relies on the fact that the off-diagonal anisotropic contributions to the electric polarizability tensor for two enantiomers have different signs. Exploiting this property, we are able to excite a coherent unidirectional rotation of two enantiomers with a π phase difference in the molecular electric dipole moment. The approach is robust and suitable for relatively high temperatures of molecular samples, making it applicable for selective chiral analysis of mixtures, and to chiral molecules with low barriers between enantiomers. As an illustration, we present nanosecond laser-driven dynamics of a tetratomic non-rigid chiral molecule with short-lived chirality. The ultrafast time scale of the proposed technique is well suited to study parity violation in molecular systems in short-lived chiral states.

description: Achieving a high level of immersion and adaptation in virtual reality (VR) requires precise measurement and representation of user state. While extrinsic physical characteristics such as locomotion and pose can be accurately tracked in real-time, reliably capturing mental states is more challenging. Quantitative psychology allows considering more intrinsic features like emotion, attention, or cognitive load. Time perception, in particular, is strongly tied to users' mental states, including stress, focus, and boredom. However, research on objectively measuring the pace at which we perceive the passage of time is scarce. In this work, we investigate the potential of electroencephalography (EEG) as an objective measure of time perception in VR, exploring neural correlates with oscillatory responses and time-frequency analysis. To this end, we implemented a variety of time perception modulators in VR, collected EEG recordings, and labeled them with overestimation, correct estimation, and underestimation time perception states. We found clear EEG spectral signatures for these three states, that are persistent across individuals, modulators, and modulation duration. These signatures can be integrated and applied to monitor and actively influence time perception in VR, allowing the virtual environment to be purposefully adapted to the individual to increase immersion further and improve user experience.

description: We study the half-filled Hubbard model on the triangular lattice with spin-dependent Kitaev-like hopping. Using the variational cluster approach, we identify five phases: a metallic phase, a non-coplanar chiral magnetic order, a $120^\circ$ magnetic order, a nonmagnetic insulator (NMI), and an interacting Chern insulator (CI) with a nonzero Chern number. The transition from CI to NMI is characterized by the change of the charge gap from an indirect band gap to a direct Mott gap. Based on the slave-rotor mean-field theory, the NMI phase is further suggested to be a gapless Mott insulator with a spinon Fermi surface or a fractionalized CI with nontrivial spinon topology, depending on the strength of Kitaev-like hopping. Our work highlights the rising field that interesting phases emerge from the interplay of band topology and Mott physics.

description: Most existing studies of the angular momentum evolution of young stellar populations have focused on the youngest (1-3 Myr) T Tauri stars. In contrast, the angular momentum distributions of older T Tauri stars (4-10 Myr) have been less studied, even though they hold key insight to understanding stellar angular momentum evolution at a time when protoplanetary disks have largely dissipated and when models therefore predict changes in the rotational evolution that can in principle be tested. We present a study of photometric variability among 1,974 confirmed T Tauri members of various sub-regions of the Orion OB1 association, and with ages spanning 4-10 Myr, using optical time-series from three different surveys. For 564 of the stars (~32% of the weak-lined T Tauri stars and ~13% of the classical T Tauri stars in our sample) we detect statistically significant periodic variations which we attribute to the stellar rotation periods, making this one of the largest samples of T Tauri star rotation periods yet published. We observe a clear change in the overall rotation period distributions over the age range 4-10 Myr, with the progressively older sub-populations exhibiting systematically faster rotation. This result is consistent with angular momentum evolution model predictions of an important qualitative change in the stellar rotation periods starting at ~5 Myr, an age range for which very few observational constraints were previously available.

description: Some recently discovered short-period Earth to Neptune sized exoplanets (super Earths) have low observed mean densities which can only be explained by voluminous gaseous atmospheres. Here, we study the conditions allowing the accretion and retention of such atmospheres. We self-consistently couple the nebular gas accretion onto rocky cores and the subsequent evolution of gas envelopes following the dispersal of the protoplanetary disk. Specifically, we address mass-loss due to both photo-evaporation and cooling of the planet. We find that planets shed their outer layers (dozens of percents in mass) following the disk's dispersal (even without photo-evaporation), and their atmospheres shrink in a few Myr to a thickness comparable to the radius of the underlying rocky core. At this stage, atmospheres containing less particles than the core (equivalently, lighter than a few % of the planet's mass) can be blown away by heat coming from the cooling core, while heavier atmospheres cool and contract on a timescale of Gyr at most. By relating the mass-loss timescale to the accretion time, we analytically identify a Goldilocks region in the mass-temperature plane in which low-density super Earths can be found: planets have to be massive and cold enough to accrete and retain their atmospheres, while not too massive or cold, such that they do not enter runaway accretion and become gas giants (Jupiters). We compare our results to the observed super-Earth population and find that low-density planets are indeed concentrated in the theoretically allowed region. Our analytical and intuitive model can be used to investigate possible super-Earth formation scenarios.

description: Deuterium is created during Big Bang Nucleosynthesis, and, in contrast to the other light stable nuclei, can only be destroyed thereafter by fusion in stellar interiors. In this paper we study the cosmic evolution of the deuterium abundance in the interstellar medium and its dispersion using realistic galaxy evolution models. We find that models that reproduce the observed metal abundance are compatible with observations of the deuterium abundance in the local ISM and z ~ 3 absorption line systems. In particular, we reproduce the low astration factor which we attribute to a low global star formation efficiency. We calculate the dispersion in deuterium abundance arising from different structure formation histories in different parts of the Universe. Our model also predicts an extremely tight correlation between deuterium and metal abundances which could be used to measure the primordial deuterium abundance.

Impacts of a Flaring Star-forming Disc and Stellar Radial Mixing on the Vertical Metallicity Gradient

description: Using idealised N-body simulations of a Milky Way-sized disc galaxy, we qualitatively study how the metallicity distributions of the thin disc star particles are modified by the formation of the bar and spiral arm structures. The thin disc in our numerical experiments initially has a tight negative radial metallicity gradient and a constant vertical scale-height. We show that the radial mixing of stars drives a positive vertical metallicity gradient in the thin disc. On the other hand, if the initial thin disc is flared, with vertical scale-height increasing with galactocentric radius, the metal poor stars originally in the outer disc become dominant in regions above the disc plane at every radii. This process can drive a negative vertical metallicity gradient, which is consistent with the current observed trend. This model mimics a scenario where the star-forming thin disc was flared in the outer region at earlier epochs. Our numerical experiment with an initial flared disc predicts that the negative vertical metallicity gradient of the mono-age relatively young thin disc population should be steeper in the inner disc, and the radial metallicity gradient of the mono-age population should be shallower at greater heights above the disc plane. We also predict that the metallicity distribution function of mono-age young thin disc populations above the disc plane would be more positively skewed in the inner disc compared to the outer disc.

Coulomb and electron-phonon interactions in metals

description: An accurate and consistent theory of phonons in metals requires that all long-range Coulomb interactions between charged particles (electrons and ions) be treated on equal footing. So far, all attempts to deal with this non-perturbative system were relying on uncontrolled approximations in the absence of small parameters. In this work, we develop the Diagrammatic Monte Carlo approach for a two-component Coulomb system that obtains the solution to this fundamental problem in an approximation free way by computing vertex corrections from higher-order skeleton graphs. The feasibility of the method is demonstrated by calculating the spectrum of longitudinal acoustic phonons in a simple cubic lattice, determining their sound velocity, and obtaining the phonon spectral densities by analytic continuation of the Matsubara Green's functions. Final results are checked against the lowest-order fully self-consistent GW-approximation in both adiabatic and non-adiabatic regimes.

description: The particle creation by the so-called peak electric field is considered. The latter field is a combination of two exponential parts, one exponentially increasing and another exponentially decreasing. We find exact solutions of the Dirac equation with the field under consideration with appropriate asymptotic conditions and calculate all the characteristics of particle creation effect, in particular, differential mean numbers of created particle, total number of created particles, and the probability for a vacuum to remain a vacuum. Characteristic asymptotic regimes are discussed in detail and a comparison with the pure asymptotically decaying field is considered.
