description: A novel high-resolution method for forecasting cloud motion from all-sky images using deep learning is presented. A convolutional neural network (CNN) was created and trained with more than two years of all-sky images, recorded by a hemispheric sky imager (HSI) at the Institute of Meteorology and Climatology (IMUK) of the Leibniz Universität Hannover, Hannover, Germany. Using the haze indexpostprocessing algorithm, cloud characteristics were found, and the deformation vector of each cloud was performed and used as ground truth. The CNN training process was built to predict cloud motion up to 10 min ahead, in a sequence of HSI images, tracking clouds frame by frame. The first two simulated minutes show a strong similarity between simulated and measured cloud motion, which allows photovoltaic (PV) companies to make accurate horizon time predictions and better marketing decisions for primary and secondary control reserves. This cloud motion algorithm principally targets global irradiance predictions as an application for electrical engineering and in PV output predictions. Comparisons between the results of the predicted region of interest of a cloud by the proposed method and real cloud position show a mean Sørensen–Dice similarity coefficient (SD) of 94 ± 2.6% (mean ± standard deviation) for the first minute, outperforming the persistence model (89 ± 3.8%). As the forecast time window increased the index decreased to 44.4 ± 12.3% for the CNN and 37.8 ± 16.4% for the persistence model for 10 min ahead forecast. In addition, up to 10 min global horizontal irradiance was also derived using a feed-forward artificial neural network technique for each CNN forecasted image. Therefore, the new algorithm presented here increases the SD approximately 15% compared to the reference persistence model.

description: In this work, we discuss the relativistic Landau-He-McKellar-Wilkens quantization and relativistic bound states solutions for a Dirac neutral particle under the influence of a Coulomb-like potential induced by the Lorentz symmetry breaking effects. We present new possible scenarios of studying Lorentz symmetry breaking effects by fixing the space-like vector field background in special configurations. It is worth mentioning that we use the criterion for studying the violation of Lorentz symmetry is that the gauge symmetry should be preserved.

description: Virtually all republican constitutions foresee mechanisms to ensure the continuous functioning of the presidency as the highest-ranking institution. While such rules have been most prominently discussed in the context of constitutional crises, they also apply to other instances, e.g. resignation or temporary unavailability due to illness or international travel. However, the rules governing temporary presidential succession still belong to the lesser researched topics in political science and comparative constitutional law. This paper provides an overview of the constitutional stipulations on acting presidents and their powers in 31 European republics. Thereby, it compares the formal-legal arrangements and defines different models of temporary succession. Furthermore, it discusses the practical applications of the rules by referring to illustrative examples from selected cases.

description: Neptune-sized extrasolar planets that orbit relatively close to their host stars -- often called "hot Neptunes" -- are common within the known population of exoplanets and planetary candidates. Similar to our own Uranus and Neptune, inefficient accretion of nebular gas is expected produce hot Neptunes whose masses are dominated by elements heavier than hydrogen and helium. At high atmospheric metallicities of 10-10,000x solar, hot Neptunes will exhibit an interesting continuum of atmospheric compositions, ranging from more Neptune-like, H2-dominated atmospheres to more Venus-like, CO2-dominated atmospheres. We explore the predicted equilibrium and disequilibrium chemistry of generic hot Neptunes and find that the atmospheric composition varies strongly as a function of temperature and bulk atmospheric properties such as metallicity and the C/O ratio. Relatively exotic H2O, CO, CO2, and even O2-dominated atmospheres are possible for hot Neptunes. We apply our models to the case of GJ 436b, where we find that a CO-rich, CH4-poor atmosphere can be a natural consequence of a very high atmospheric metallicity. From comparisons of our results with Spitzer eclipse data for GJ 436b, we conclude that although the spectral fit from the high-metallicity forward models is not quite as good as the fit obtained from pure retrieval methods, the atmospheric composition predicted by these forward models is more physically and chemically plausible. High-metallicity atmospheres (orders of magnitude in excess of solar) should therefore be considered as a possibility for GJ 436b and other hot Neptunes.

description: Context. The interaction between stellar winds and the interstellar medium (ISM) can create complex bow shocks. The photometers on board the Herschel Space Observatory are ideally suited to studying the morphologies of these bow shocks. Aims. We aim to study the circumstellar environment and wind-ISM interaction of the nearest red supergiant, Betelgeuse. Methods. Herschel PACS images at 70, 100, and 160 micron and SPIRE images at 250, 350, and 500 micron were obtained by scanning the region around Betelgeuse. These data were complemented with ultraviolet GALEX data, near-infrared WISE data, and radio 21 cm GALFA-HI data. The observational properties of the bow shock structure were deduced from the data and compared with hydrodynamical simulations. Results. The infrared Herschel images of the environment around Betelgeuse are spectacular, showing the occurrence of multiple arcs at 6-7 arcmin from the central target and the presence of a linear bar at 9 arcmin. Remarkably, no large-scale instabilities are seen in the outer arcs and linear bar. The dust temperature in the outer arcs varies between 40 and 140 K, with the linear bar having the same colour temperature as the arcs. The inner envelope shows clear evidence of a non-homogeneous clumpy structure (beyond 15 arcsec), probably related to the giant convection cells of the outer atmosphere. The non-homogeneous distribution of the material even persists until the collision with the ISM. A strong variation in brightness of the inner clumps at a radius of 2 arcmin suggests a drastic change in mean gas and dust density some 32 000 yr ago. Using hydrodynamical simulations, we try to explain the observed morphology of the bow shock around Betelgeuse. Conclusions: [abbreviated]

description: The avoidability of binary patterns by binary cube-free words is investigated and the exact bound between unavoidable and avoidable patterns is found. All avoidable patterns are shown to be D0L-avoidable. For avoidable patterns, the growth rates of the avoiding languages are studied. All such languages, except for the overlap-free language, are proved to have exponential growth. The exact growth rates of languages avoiding minimal avoidable patterns are approximated through computer-assisted upper bounds. Finally, a new example of a pattern-avoiding language of polynomial growth is given.

description: I consider the generic model independent predictions of the theory of quantum cosmological perturbations. To describe the stage of cosmic inflation, where these perturbations are amplified, the hydrodynamical approch is used. The inflationary stage is completely characterized by the deviation of the equation of state from cosmological constant which is a smooth function of the number of e-folds until the end of inflation. It is shown that in this case the spectral index should deviate from the flat one at least by 3 percent irrespective of any particular scenario. Given the value of the spectral index the lower bound on the amount of the gravitational waves produced is derived. Finally the relation between effective hydrodynamical description of inflation and inflationary scenarios is discussed.

description: Ditomina is a subtribe of ground beetles included in the large tribe Harpalini, with most species restricted to the Mediterranean basin. To date, affinities within Harpalini have mainly been derived from morphological data, and the placement of several genera within Ditomina has been subject to discussion. In this study we provide a regional molecular phylogeny for Ditomina with representatives from seven of the eight known genera from the West Mediterranean region, the Australian Phorticosomus Schaum, 1862, and selected Harpalini outgroup taxa. DNA sequences from two different markers, the mitochondrial protein coding gene cox1 and the nuclear gene ITS2, were sequenced and analysed from 19 taxa. Molecular phylogenetic analyses consistently support (i) the sister relationship of genera Carterus Dejean, 1830 and Eocarterus Stichel, 1923; (ii) a close relationship among Ditomus Bonelli, 1810, Tschitscherinellus Csiki, 1906 and Odontocarus Solier, 1835, which form a lineage well separated from Dixus Billberg, 1820; and (iii) the exclusion of Graniger Motschulsky, 1864 and the Australian Phorticosomus from the subtribe Ditomina. In addition, phylogenetic trees indicate a vicariance event for the brachypterous genus Eocarterus on both sides of the Strait of Gibraltar, followed by further geographical differentiation in southern Iberia and northern Morocco. This pattern contrasts with the distribution of various fully winged species of ground beetles on both sides of the same barrier, suggesting the role of dispersal limitation in speciation. Finally, a new key to supraspecific taxa of the Ditomina of the West Mediterranean region is provided.

The calculations reveal that sub-mHz accuracy is required to detect such tiny effects in this class of compounds, and that parity violation effects are very sensitive to the choice of ligands.

description: We report the detections of planetary companions orbiting around three evolved intermediate-mass stars from precise radial velocity measurements at Okayama Astrophysical Observatory. HD 2952 (K0III, 2.5 M_sun) and omega Ser (G8III, 2.2 M_sun) host a relatively low mass planet with minimum mass of m_2sin i=1.6 M_J and 1.7 M_J in nearly circular orbits with period of P=312 and 277 d, respectively. HD 120084 (G7 III, 2.4 M_sun) hosts an eccentric planet with m_2sin i=4.5 M_J in an orbit with P=2082 d and eccentricity of e=0.66. The planet has one of the largest eccentricities among those ever discovered around evolved intermediate-mass stars, almost all of which have eccentricity smaller than 0.4. We also show that radial velocity variations of stellar oscillations for G giants can be averaged out below a level of a few m/s at least in timescale of a week by high cadence observations, which enables us to detect a super-Earth and a Neptune-mass planet in short-period orbits even around such giant stars.

description: In recent years, deep learning models have become very powerful – even outperforming humans on a variety of tasks. This enables more real-world applications, including also sensitive fields such as medical diagnoses or jurisdiction. Besides achieving sufficiently good performance, the requirement to justify and explain the models’ decisions is becoming increasingly important. This work aims to enable a broader application of a specific model class that is inherently interpretable, namely explain-then-predict models, by reducing the annotation cost of the explanations. We focus on the ExPred model as a representative of explain-then-predict models. We investigate its dependency on rationale annotations, a special kind of explanation, through training using gradually fewer rationale-labeled instances. Furthermore, we ex- plore different approaches that aim to reduce the number of human-labeled instances required during training, such as active learning and weak supervision. Our results show that even with only a fraction of instances annotated with rationales from the original dataset, ExPred still achieves good performance (within 95% of the performance when using 100% annotation). Depending on the dataset, only a few thousand annotated rationales are required. Using weak supervision, this can be further reduced, at least in specific settings. On the Movie Reviews dataset, we achieve good performance with only 5% of the original rational labels. The tested off-the-shelf active learning methods do not provide any benefit over randomly selecting instances to label. However, the extensive behavior analysis enables the future design of active learning methods that are tailored to explain-then-predict models. We start by proposing an active learning method that outperforms the random baseline on the Movie Reviews dataset.
Rotational constants of multi-phonon bands in an effective theory for deformed nuclei

Year: 2013

description: We consider deformed nuclei within an effective theory that exploits the small ratio between rotational and vibrational excitations. For even-even nuclei, the effective theory predicts small changes in the rotational constants of bands built on multi-phonon excitations that are linear in the number of excited phonons. In 166Er and 168Er, this explains the main variations of the rotational constants of the two-phonon gamma vibrational bands. In 232Th, the effective theory correctly explains the trend that the rotational constants decrease with increasing spin of the band head. We also study the effective theory for deformed odd nuclei. Here, time-odd terms enter the Lagrangian and generate effective magnetic forces that yield the high level densities observed in such nuclei.

The monophyly of Anisoedessa was supported by four synapomorphies: presence of dorsoposterior ridge on the proctiger; presence of ventroposterior margin, forming a lip on the proctiger, except in A. flavomaculata; proctiger excavated latero-posteriorly, except in A. flavomaculata; and ventral metallic sheen on abdominal intersegments. Forty-eight characters were selected from 28 taxa, 22 of which form the ingroup, including Anisoedessa (6 spp.), Ascra (1 sp.), Brachystethus (1 sp.), Doesburgedessa (2 spp.), Edessa (4 spp.), Grammedessa (2 spp.), Olbia (1 sp.), Paraedessa (2 spp.), Pantochlora (1 sp.), Peromatus (1 sp.), Plagaedessa (2 spp.), and Pygoda (1 sp.); and four outgroup taxa, Neotibilis sp., Serdia, and Lopadusa spp. (2 spp.). Phylogenetic analyses were conducted using TNT. Bootstrap and Bremer support in TNT showed statistical support for the monophyly of Edessinae and Anisoedessa; indicated Edessa as polyphyletic; and some support for natural groupings of Doesburgedessa, Grammedessa, and Paraedessa, although further analysis is needed in testing the monophyly of these genera. A key, diagnoses, descriptions as well as select images and illustrations of morphological features are provided for all species of Anisoedessa, as are geographical distributions on an illustrated map.

description: Adhesive wear in dry contacts is often described using the Archard or Fleischer model. Both provide equations for the determination of a wear volume, taking the load, the sliding path and a set of material parameters into account. While the Fleischer model is based on energetic approaches, the Archard formulation uses an empirical factor-the wear coefficient-describing the intensity of wear. Today, a numerical determination of the wear coefficient is already possible and both approaches can be deduced to a local accumulation of friction energy. The aim of this work is to enhance existing energy-based wear models into the mixed lubrication regime. Therefore, the pressure distribution within the contact area will be determined numerically taking real surface topographies into account. The emerging contact area will be divided into one part of solid and a second part of elastohydrodynamically lubricated (EHL) contacts. Based on the resulting pressure and shear stress distribution, the formation of micro cracks within the loaded volume will be described. Determining a critical number of load cycles for each asperity, a locally resolved wear coefficient will be derived and the local wear depth calculated.

Moreover, we prove that, for a C2-generic Hamiltonian H, the union of the partially hyperbolic regular energy hypersurfaces and the closed elliptic orbits, forms a dense subset of M. As a consequence, any robustly transitive regular energy hypersurface of a C2-Hamiltonian is partially hyperbolic. Finally, we prove that stably weakly shadowable regular energy hypersurfaces are partially hyperbolic.

description: In this paper we present a paradigmatic tight-binding model for single-layer as well as for multi-layered semiconducting MoS$_2$ and similar transition metal dichalcogenides. We show that the electronic properties of multilayer systems can be reproduced in terms of a tight-binding modelling of the single-layer hopping terms by simply adding the proper interlayer hoppings ruled by the chalcogenide atoms. We show that such tight-binding model permits to understand and control in a natural way the transition between a direct-gap band structure, in single-layer systems, to an indirect gap in multilayer compounds in terms of a momentum/orbital selective interlayer splitting of the relevant valence and conduction bands. The model represents also a suitable playground to investigate in an analytical way strain and finite-size effects.

Here we demonstrate that multiple stacks patterned on the same Bi2Sr2CaCu2O8+delta crystal can - under optimized conditions - be synchronized to emit high-power THz-radiation. For three synchronized stacks we achieved 610 microwatts of continuous-wave coherent radiation power at 0.51 THz. We suggest that synchronization is promoted by THz-waves in the base crystal. We note though that synchronization cannot be achieved in all samples. However, even in these cases powers on the 100-microwatt scale can be generated.

description: Nowadays, scientific articles are mostly published as PDF files containing unstructured and semi-structured text. This way of scholarly communication severely limits the possibilities to automatically process and reuse scholarly knowledge. As a consequence, applying data analysis methods to scientific literature is a non-trivial process. FAIR scholarly knowledge graphs (SKGs) is one approach to represent scholarly knowledge in a structured, machineactionable, and semantic manner. In this thesis, we exploit SKGs, specifically the Open Research Knowledge Graph (ORKG), in data science. We introduce a generic architecture for applying data science to scholarly data. We then implement the architecture using the ORKG as the main data source and test it in two use cases in different domains. We demonstrate approaches that reuse the ORKG content to draw new insights and build applications and visualizations on top of SKGs data.

Depuis une décennie, l’engagement des patients et de leurs familles est reconnu pour contribuer à l’amélioration de la qualité et de la sécurité des soins. En matière de sécurité, les patients peuvent jouer un rôle décisif pour prévenir et réduire les situations à risque pour leur santé. Au Canada, de nombreuses initiatives d’engagement des patients ont vu le jour à différents niveaux (politique, organisation des soins, soins directs). Grâce aux travaux et aux efforts d’institutions et d’acteurs, cet engagement des patients dans la sécurité a pris de l’ampleur dans les établissements de santé et dans les milieux de soins. Le présent article propose une synthèse du Guide de l’engagement des patients en matière de sécurité, publié par l’Institut canadien pour la sécurité des patients. Ce guide donne un aperçu des initiatives prometteuses mises en place au Canada pour impliquer les patients et leurs familles dans la sécurité des soins. Il met aussi à disposition un ensemble de ressources et d’outils, élaborés au Canada et ailleurs, pour faciliter l’engagement des patients dans la sécurité. Ce guide est une ressource utile pour aider les patients et leurs familles, les professionnels de la santé, les gestionnaires et l’ensemble des acteurs du système de santé à collaborer pour améliorer la sécurité des patients.

description: We searched for a sidereal modulation in the rate of neutrinos produced by the NuMI beam and observed by the MINOS far detector. The detection of such harmonic signals could be a signature of neutrino-antineutrino mixing due to Lorentz and CPT violation as described by the Standard Model Extension framework. We found no evidence for these sidereal signals and we placed limits on the coefficients in this theory describing the effect. This is the first report of limits on these neutrino-antineutrino mixing coefficients.

description: The boron isotopic composition (δ11B) of benthic foraminifera provides a valuable tool to reconstruct past deep-water pH. As the abundance of monospecific species might be limited in sediments, microanalytical techniques can help to overcome this problem, but such studies on benthic foraminiferal δ11B are sparse. In addition, microanalytics provide information on the distribution of δ11B at high spatial resolution to increase the knowledge of biomineralization processes, for example. For this study, we investigated the intra- and inter-shell δ11B variability of the epibenthic species Cibicidoides wuellerstorfi, which is widely used in paleoceanography, by secondary ion mass spectrometry (SIMS) and femtosecond laser ablation multicollector inductively coupled plasma mass spectrometry (LA-MC-ICPMS). While the average δ11B values obtained from these different techniques agree remarkably well with bulk solution values to within -0:1 %, a relatively large intra-shell variability was observed. Based on multiple measurements within single shells, the SIMS and LA data suggest median variations of 4.8% and 1.3% (2s), respectively, while the larger spread for SIMS is attributed to the smaller volume of calcite being analyzed in each run. When analytical uncertainties and volume-dependent differences in δ11B variations are taken into account for these methods, the intra-shell variability is estimated to be on the order of ~ 3% and ~ 0:4% (2s) on a ~ 20 and 100 µm scale, respectively. In comparison, the δ11B variability between shells exhibits a total range of ~ 3% for both techniques, suggesting that several shells need to be analyzed for accurate mean δ11B values. Based on a simple resampling method, we conclude that ~ 12 shells of C. wuellerstorfi must be analyzed using LA-MC-ICPMS to obtain an accurate average value within -0:5% (2s) to resolve pH variations of ~ 0:1. Based on our findings, we suggest preferring the conventional bulk solution MC-ICPMS over the in situ methods for paleo-pH studies, for example. However, SIMS and LA provide powerful tools for highresolution paleoreconstructions, or for investigating ontogenetic trends in δ11B. © Author(s) 2020.

description: Dense matter as it can be found in core-collapse supernovae and neutron stars is expected to exhibit different phase transitions which impact the matter composition and the equation of state, with important consequences on the dynamics of core-collapse supernova explosion and on the structure of neutron stars. In this paper we will address the specific phenomenology of two of such transitions, namely the crust-core solid-liquid transition at sub-saturation density, and the possible strange transition at super-saturation density in the presence of hyperonic degrees of freedom. Concerning the neutron star crust-core phase transition at zero and finite temperature, it will be shown that, as a consequence of the presence of long-range Coulomb interactions, a clusterized phase is expected which is not accessible in the grand-canonical ensemble. A specific quasi-particle model will be introduced and some quantitative results relevant for the supernova dynamics will be shown. The opening of hyperonic degrees of freedom at higher densities corresponding to the neutron stars core also modifies the equation of state. The general characteristics and order of phase transitions in this regime will be analyzed in the framework of a self-consistent mean-field approach.

Leptonic final states from di-boson production at the LHC in the 4-Dimensional Composite Higgs Model

description: We study di-boson production via both neutral and charged current at the Large Hadron Collider, i.e. subprocesses $q\bar q\to e^+ν_e μ^-\barν_μ$ + ${\rm{c.c.}}$ and $q\bar q'\to l^+ν_l l^{'+}l^{'-}$ + ${\rm{c.c.}}$, respectively, where $q,q'$ are quarks and $l,l'=e,μ$, in all possible combinations, in the context of the 4-Dimensional Composite Higgs Model. These modes enable the production in the intermediate steps of several additional -- with respect to the Standard Model -- neutral and charged gauge bosons belonging to the spectrum of this scenario, all of which in resonant topologies. We not only find these channels to be accessible over the background but also show that, after a dedicated cut-based analysis, kinematic reconstruction of most such resonances is always possible. However, since the Electro-Weak precision data generally disfavor neutral and charged gauge boson masses below the TeV range and also their large couplings to light-fermions, these modes turn out to be relevant only for the 14 TeV option with high integrated luminosity.
Fluid phonons, protoinflationary dynamics and large-scale gravitational fluctuations

description: We explore what can be said on the effective temperature and sound speed of a statistical ensemble of fluid phonons present at the onset of a conventional inflationary phase. The phonons are the actual normal modes of the gravitating and irrotational fluid that dominates the protoinflationary dynamics. The bounds on the tensor to scalar ratio result in a class of novel constraints involving the slow roll parameter, the sound speed of the phonons and the temperature of the plasma prior to the onset of inflation. If the current size of the Hubble radius coincides with the inflationary event horizon redshifted down to the present epoch, the sound speed of the phonons can be assessed from independent measurements of the tensor to scalar ratio and of the tensor spectral index.

description: The Drosophila buzzatii cluster is a South American clade that encompasses seven closely related cactophilic species and constitutes a valuable model system for evolutionary research. Though the monophyly of the cluster is strongly supported by molecular, cytological and morphological evidence, phylogenetic relationships within it are still controversial. The phylogeny of the D. buzzatii cluster has been addressed using limited sets of molecular markers, namely a few nuclear and mitochondrial genes, and the sharing of fixed chromosomal inversions. However, analyses based on these data revealed inconsistencies across markers and resulted in poorly resolved basal branches. Here, we revise the phylogeny of the D. buzzatii cluster based on a large transcriptomic dataset of 813 kb obtained from four members of this cluster: D. antonietae, D. borborema, D. buzzatii and D. koepferae, using the close relative D. mojavensis (also a member of the repleta group) as outgroup. Our phylogenomic analyses confirm that D. buzzatii is sister to the other six members of the cluster and, though incomplete lineage sorting likely obstructs phylogenetic resolution among these six species, allowed us to recover a novel topology. Divergence time estimates date the radiation of the cluster to the recent upper Pleistocene with most speciation events compressed to the last 500,000 years.
title: Morphology and evolution of spider book lungs (Araneae)

description: Book lungs are an iconic character for arachnids, yet previous accounts of their morphology in spiders (Arachnida: Araneae) are based on sporadic reports from a few species using a diverse suite of terminologies. Here, we focus on the fine structure of spider book lungs using standardized terminology and a wider taxon sampling of seven species studied as histological sections and forty species studied with scanning electron microscopy. All spider lungs share a similar basic morphology, which also matches the ground pattern for arachnids in general. This includes a spiracle opening into an atrium with a folded wall from which stacked lamellae containing pillar cells project into a haemolymph sinus. The air spaces are separated by proximal trabeculae, which span the space completely, and distal trabeculae which originate from the lamellar dorsal surface. Within this framework, several differences amongst spider lungs could be identified. Distal trabeculae can be pilate or reticulate. Lamellar margins pointing into the atrium can be echinate, arbuscular-reticulate or arbuscular-reticulate-echinate. The atrium wall can be psilate, verrucate or arbuscular-reticulate. The character states identified here offer new perspectives for apomorphies of major spider clades. Reticulate distal trabeculae are only seen in the Mygalomorphae investigated here. The arbuscular-reticulate condition on the lamellar margin is only seen in representatives of Opisthothelae; with a further modification to arbuscular-reticulate-echinate in the Ctenidae. With one notable exception, an arbuscular-reticulate atrium wall is seen in the Araneomorphae sampled. These data are further compared to other pulmonate arachnids. Book lung fine structure in the earliest branching spider clade – the Mesothelae – matches the condition observed for the closely related Amblypygi (whip spiders).
