description: Diltiazem (DZ) is widely prescribed in transplant recipients because of its drug-drug interactions with calcineurin inhibitors (CNI). However, these interactions have been primarily investigated in renal transplantation, and data regarding the long-term efficacy and safety of DZ in orthotopic heart transplantation (OHT) are still sparse. Our study aimed to elucidate the extent to which the co-prescription of DZ reduces the dose required to maintain adequate blood levels of cyclosporine A (CsA) and the resulting effect on morbidity and mortality in OHT recipients. We performed a retrospective single-center analysis of OHT recipients on a long-term immunosuppressive regimen based on CsA and mycophenolate mofetil (MMF). The study population consisted of 95 adult OHT recipients with a mean follow-up of 15.8 ± 6.7 years. DZ was co-prescribed in 39 subjects (41.1%) and was associated with a 28.6% reduction of the mean CsA daily dose (P < .001). Patients on DZ had less frequent rejection episodes (P = .002), better renal function (P = .009) and a lower rate of end-stage renal disease (P = .008). Additionally, they developed later cardiac allograft vasculopathy (CAV). We observed no prognostic relevance of DZ co-prescription in univariate and multivariate Cox-regression analyses. In addition to reducing the CsA dose required to maintain adequate blood through levels, DZ may have nephroprotective properties in OHT. The co-administration of DZ may decelerate the development of CAV and reduce the frequency of the rejection episodes. However, the beneficial influence on morbidity has no impact on mortality.

description: Im Rahmen dieser Bachelorarbeit wird ein dreidimensionales sogenanntes ”Makro-Element“ mit linearen Ansatzfunktionen entwickelt und verifiziert, das für die Lösung statischer Probleme für nichtlinear elastisches und inelastisches Materialverhalten geeignet ist, fokussierend auf Situationen, die unerwünschte Nebeneffekte wie Locking oder Hourglassing hervorrufen können. Das Makro-Element basiert auf dem in (I) entwickelte 3D Cosserat Brick Element, das sich in der Behebung von Locking und Hourglassing bewährt hat. Das Makro-Element wird in kleine Elemente, sogenannte Mikro- oder Subelemente unterteilt, in denen erstmal die Spannungen wie in einem rein homogenen 3D Cosserat Brick Element berechnet und dann auf das ursprüngliche Element abgebildet werden. Aus diesem Grund wurde das Element ”Makro-Element“ getauft. Ein schöner Nebeneffekt bei der Verwendung dieses Elementes ist der Verzicht auf die numerische Integration über das Gebiet aufgrund einer speziell entwickelten Kinematik. In dem ersten Teil dieser Arbeit wird die Theorie des Makro-Elementes für das nichtlineare, elastische Materialverhalten vorgestellt. Das implementierte Element wird einem Patch-Test und anderen Tests unterzogen, um es auf seine Richtigkeit zu überprüfen, und um sein Verhalten in heiklen Situationen im Vergleich zu anderen Elementen zu evaluieren. Im zweiten Teil wird die Theorie um das inelastische, insbesondere um das nichtlineare, plastische Materialverhalten erweitert. Es wird die Von-Mises-Plastizität verwendet mit Beschränkung auf isotrope Verfestigung. Das plastische Modell wird mit Hilfe des Radial-Return-Mapping-Algorithmus numerisch umgesetzt. Diese Erweiterung im Element wird implementiert und für einen speziellen Fall untersucht.

description: Quantum entanglement in 3 spatial dimensions is studied in systems with physical boundaries when an entangling surface intersects the boundary. We show that there are universal logarithmic boundary terms in the entanglement Rényi entropy and derive them for different conformal field theories and geometrical configurations. The paper covers such topics as spectral geometry on manifolds with conical singularities crossing the boundaries, the dependence of the entanglement entropy on mutual position of the boundary and the entangling surface, effects of acceleration and rotation of the boundary, relations of coefficients in the trace anomaly to coefficients in the boundary logarithmic terms in the entropy. The computations are done for scalar, spinor and gauge fields.

description: We present novel continuous supersymmetric transitions which take place among different chiral configurations of D3/D7 branes at singularities in the context of type IIB Calabi-Yau compactifications. We find that distinct local models which admit a consistent global embedding can actually be connected to each other along flat directions by means of transitions of bulk-to-flavour branes. This has interesting interpretations in terms of brane recombination/splitting and brane/anti-brane creation/annihilation. These transitions give rise to a large web of quiver gauge theories parametrised by splitting/recombination modes of bulk branes which are not present in the non-compact case. We illustrate our results in concrete global embeddings of chiral models at a dP_0 singularity.

description: The next generation of galaxy surveys, aiming to observe millions of galaxies, are expensive both in time and cost. This raises questions regarding the optimal investment of this time and money for future surveys. In a previous work, it was shown that a sparse sampling strategy could be a powerful substitute for the contiguous observations. However, in this previous paper a regular sparse sampling was investigated, where the sparse observed patches were regularly distributed on the sky. The regularity of the mask introduces a periodic pattern in the window function, which induces periodic correlations at specific scales. In this paper, we use the Bayesian experimental design to investigate a random sparse sampling, where the observed patches are randomly distributed over the total sparsely sampled area. We find that, as there is no preferred scale in the window function, the induced correlation is evenly distributed amongst all scales. This could be desirable if we are interested in specific scales in the galaxy power spectrum, such as the Baryonic Acoustic Oscillation (BAO) scales. However, for constraining the overall galaxy power spectrum and the cosmological parameters, there is no preference over regular or random sampling. Hence any approach that is practically more suitable can be chosen and we can relax the regular-grid condition for the distribution of the observed patches.

description: Recent Hubble Space Telescope (HST) observations have revealed that a majority of active galactic nuclei (AGN) at z ~ 1-3 are resident in isolated disk galaxies, contrary to the usual expectation that AGN are triggered by mergers. Here we develop a new test of the cosmic evolution of supermassive black holes (SMBHs) in disk galaxies by considering the local population of SMBHs. We show that substantial SMBH growth in spiral galaxies is required as disks assemble. SMBHs exhibit a tight relation between their mass and the velocity dispersion of the spheroid within which they reside, the M_BH-sigma relation. In disk galaxies the bulge is the spheroid of interest. We explore the evolution of the M_BH-sigma relation when bulges form together with SMBHs on the M_BH-sigma relation and then slowly reform a disk around them. The formation of the disk compresses the bulge raising its sigma. We present evidence for such compression in the form of larger velocity dispersion of classical bulges compared with elliptical galaxies at the same mass. This compression leads to an offset in the M_BH-sigma relation if it is not accompanied by an increased M_BH. We quantify the expected offset based on photometric data and show that, on average, SMBHs must grow by ~ 50-65% just to remain on the M_BH-sigma relation. We find no significant offset in the M_BH-sigma relations of classical bulges and of ellipticals, implying that SMBHs have been growing along with disks. Our simulations demonstrate that SMBH growth is necessary for the local population of disk galaxies to have remained on the M_BH-sigma relation.

Hyperons are found to produce bound nuclei beyond the normal nuclear driplines. Radii are found to decrease in hypernuclei near the driplines, in line with observations in light $Λ$ hypernuclei near the stability valley, The inclusion of a $Ξ^{-}$ introduces a much larger change in radii than one or more $Λ$'s.

description: Using asteroseismic data and stellar evolution models we make the first detection of a convective core in a Kepler field main-sequence star, putting a stringent constraint on the total size of the mixed zone and showing that extra mixing beyond the formal convective boundary exists. In a slightly less massive target the presence of a convective core cannot be conclusively discarded, and thus its remaining main-sequence life time is uncertain. Our results reveal that best-fit models found solely by matching individual frequencies of oscillations corrected for surface effects do not always properly reproduce frequency combinations. Moreover, slightly different criteria to define what the best-fit model is can lead to solutions with similar global properties but very different interior structures. We argue that the use of frequency ratios is a more reliable way to obtain accurate stellar parameters, and show that our analysis in field main-sequence stars can yield an overall precision of 1.5%, 4%, and 10% in radius, mass and age, respectively. We compare our results with those obtained from global oscillation properties, and discuss the possible sources of uncertainties in asteroseismic stellar modeling where further studies are still needed.

description: Hand gestures recognition (HGR) is one of the main areas of research for the engineers, scientists and bioinformatics. HGR is the natural way of Human Machine interaction and today many researchers in the academia and industry are working on different application to make interactions more easy, natural and convenient without wearing any extra device. HGR can be applied from games control to vision enabled robot control, from virtual reality to smart home systems. In this paper we are discussing work done in the area of hand gesture recognition where focus is on the intelligent approaches including soft computing based methods like artificial neural network, fuzzy logic, genetic algorithms etc. The methods in the preprocessing of image for segmentation and hand image construction also taken into study. Most researchers used fingertips for hand detection in appearance based modeling. Finally the comparison of results given by different researchers is also presented.

A part of the traces can be grouped to 8 tracks, one of which was named Rotundichnus muenchehagensis by Hendricks 1981. Additionally, a track composed of bird-like footprints of a biped dinosaur is present. The dinosaurs lived within the semiaquatic, densely wooded estuary System, which was protected by sand bars against the open sea of the Lower Saxonian Basin.

Ein Teil davon läßt sich zu;8 Fährten gruppieren, darunter die von Hendricks 1981 als Rotundiclmus muenchehagensis beschriebene. Eine weitere Fährte stammt von einem biped laufenden Saurier mit vogelartig gebautem Fuß. Die Saurier lebten in kleinen Gruppen im semiaquatischen, vegetationsreichen Milieu eines Flußmündungssystems, das gegen das offene Niedersächsische Becken durch Sandbarren abgeschlossen war.

description: The joints at the site of the dinosaur tracks in Muenchehagen form a conspicuous rhomboid pattern in a widely exposed bedding surface of the local quarry. An approximately west-trending set of joints is radially orientated with regard to the shape of the Rehburg salt pillow indicating a genetic relation to salt flow. The second set of joints trends approximately NW and is associated with arrays of dextral shear joints. Its formation is attributed to salt pillow formation and/or a regional deformation plan. This deformation plan presumably existed during the Alpine orogeny. The preservation potential of the dinosaur tracks is considerably decreased by the joint System.
description: Die Klüfte im Bereich des Naturdenkmals „Saurierfährten Münchehagen" bilden auf der örtlichen Steinbruchsohle ein auffälliges, rautenförmiges Muster. Eine etwa westlich streichende Kluftschar ist radial um den durch Salzkissenbildung entstandenen Rehburger Sattel angeordnet, so daß ihre Genese in Zusammenhang mit der Salzwanderung gesehen wird. Die Entstehung der zweiten Kluftschar, die etwa nordwestlich streicht und von dextralen Scherkluftstaffeln begleitet wird, läßt sich auf die Salzkissenbildung beziehungsweise einen regionalen Beanspruchungsplan zurückführen, der vermutlich während der Alpenorogenese bestand. Das Erhaltungspotential der im Naturdenkmal aufgeschlossenen Fährtenplatte wird durch das Kluftsystem erheblich verringert.

description: Over the last few decades, observational surveys have revealed that high-order multiple-star systems (e.g. triples, quadruples, etc.), and triples in particular, are common in our Galaxy. In this paper, we consider the dynamical significance of this transformation in our understanding of stellar multiplicity. Using empirically constrained binary and triple fractions in those star clusters for which these values are available in the literature, we compare analytic rates for encounters involving single, binary, and triple stars. Our results show that, \textit{even for relatively low triple fractions, dynamical interactions involving triples occur roughly as often as encounters involving either single or binary stars alone, particularly in low-mass star clusters}. More generally, using empirically-derived multiple star catalogues for the young star-forming association Taurus-Auriga and the Galactic field, we show that the data are consistent with the gravitationally-focused cross section for encounters increasing with increasing multiplicity. Consequently, triple stars, and even higher-order multiples, could be more important than previously realized for a number of astrophysical phenomena, including the formation and destruction of compact binaries and various types of stellar exotica, and the dynamical evolution of star clusters.

description: We study acoustic vortex in media with screw dislocation using the Katanaev-Volovich theory of defects. It is shown that the screw dislocation affects the beam's orbital angular momentum and changes the acoustic vortex strength. This change is a manifestation of topological Dirac phase and is robust against fluctuations in the system.

description: Covalent organic frameworks (COFs) are promising materials for advanced molecular-separation membranes, but their wide nanometer-sized pores prevent selective gas separation through molecular sieving. Herein, we propose a MOF-in-COF concept for the confined growth of metal-organic framework (MOFs) inside a supported COF layer to prepare MOF-in-COF membranes. These membranes feature a unique MOF-in-COF micro/nanopore network, presumably due to the formation of MOFs as a pearl string-like chain of unit cells in the 1D channel of 2D COFs. The MOF-in-COF membranes exhibit an excellent hydrogen permeance (>3000 GPU) together with a significant enhancement of separation selectivity of hydrogen over other gases. The superior separation performance for H2/CO2 and H2/CH4 surpasses the Robeson upper bounds, benefiting from the synergy combining precise size sieving and fast molecular transport through the MOF-in-COF channels. The synthesis of different combinations of MOFs and COFs in robust MOF-in-COF membranes demonstrates the versatility of our design strategy.

description: Based on its broad-band spectral energy distribution, and the X-ray spectrum in particular, the radio-loud active galactic nucleus (AGN) SDSS J102623.61+254259.5 (J1026+2542) has recently been classified as a blazar. The extremely high redshift of the source, z=5.3, makes it one of the most distant and most luminous radio-loud AGN known to date. From published 5-GHz very long baseline interferometry (VLBI) imaging data obtained in 2006, the source has a typical blazar appearance on mas scales, with a prominent one-sided jet extending to ~20 mas. We estimate the brightness temperature of J1026+2542 and find no strong evidence for Doppler boosting. The jet viewing angle is possibly at least ~20 deg. The bulk Lorentz factor and the viewing angle of the jet could reliably be determined in the near future from multi-epoch VLBI observations.

description: Heavy quarks are commonly produced in current accelerator experiments. Hence it is natural to think that they should be likewise created in collisions with larger center of mass energies like the ones involving ultra-high energy cosmic rays and atmospheric nuclei. Despite this fact, a detailed treatment of heavy hadrons is missing in Monte Carlo generators of Extensive Air Showers (EAS). It is a must to improve the description of how heavy flavours appear and evolve in atmospheric showers. With this goal in mind, we study two different models for heavy quark production in proton-air collisions. We also analyze a dedicated treatment of heavy hadrons interactions with atmospheric nuclei. This paper shows how those models have been implemented as new options available in CORSIKA, one of the most used EAS simulators. This new computational tool allows us to analyze the effects that the propagation of heavy hadrons has in the EAS development

description: Microcystin-LR (MC-LR), a potent hepatotoxin produced by the cyanobacteria, is of increasing concern worldwide because of severe and persistent impacts on humans and animals by inhalation and consumption of contaminated waters and food. In this work, MC-LR was removed completely from aqueous solution using visible-light-active C/N-co-modified mesoporous anatase/brookite TiO 2 photocatalyst. The co-modified TiO 2 nanoparticles were synthesized by a one-pot hydrothermal process, and then calcined at different temperatures (300, 400, and 500 °C). All the obtained TiO 2 powders were analyzed by X-ray diffraction (XRD), Raman spectroscopy, transmission electron microscope (TEM), specific surface area (SSA) measurements, ultraviolet-visible diffuse reflectance spectra (UV-vis DRS), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FTIR) spectroscopy, and photoluminescence (PL) analysis. It was found that all samples contained mixed-phase TiO 2 (anatase and brookite), and the content of brookite decreased with an increase in calcination temperature, as well as the specific surface area and the content of non-metal elements. The effects of initial pH value, the TiO 2 content, and MC-LR concentration on the photocatalytic activity were also studied. It was found that the photocatalytic activity of the obtained TiO 2 photocatalysts declined with increasing temperature. The complete degradation (100%) of MC-LR (10 mg L -1 ) was observed within 3 h, using as-synthesized co-modified TiO 2 (0.4 g L -1 ) at pH 4 under visible light. Based on the obtained results, the mechanism of MC-LR degradation has been proposed. © 2019 by the authors.

description: The basal bed of the Natural Monument Münchehagen, called "Sohlbank", is composed of a quartzitic sandstone. The bed is characterized by wave ripple bedding, which is altered by biotrubation. Ist surface cuts erosively older, thin sandstone layers typically covered by riplle marks on their upper bedding plane. All ripple marks are oscillation ripples which are partially modified by retreating water. Sedimentary channel fillings cut into the “Sohlbank“. A highly diverse ichnofauna is described. It comprises elements of a Cruziana ichnocenosis in addition to some traces of a Skolithos ichnocenosis. The sedimentary and biogenic structures suggest a low energy, shallow-water depositional environment.
description: Die Sohlbank des Naturdenkmals ist von kleindimensionaler Wellen-rippelschichtung dominiert, die bioturbat modifiziert ist. Ihre Oberfläche schneidet tieferliegende Flächen erosiv an, die jeweils charakteristische Muster von Oszillationsrippeln unterschiedlicher Richtung und z.T. durch ablaufendes Wasser überprägt, aufweisen. Reste von Füllungen prielartiger Entwässerungsrinnen sind in die Sohlbank eingeschnitten. Die Sohlbank weist eine diverse Ichnofauna auf. Sie wird dominiert von Formen einer Cruz/ana-lchnozönose; Elemente der Skolithos-Ichnozönose sind ihr beigemischt. Alle Sedimenttexturen zeigen ein niedrigenergetisches Flachwassermilieu an.

description: We investigate the structure and phase behavior of the Stockmayer fluid in the presence of nonuniform electric fields using molecular simulation. We find that an initially homogeneous vapor phase undergoes a local phase separation in a nonuniform field due to the combined effect of the field gradient and the fluid vapor--liquid equilibrium. This results in a high density fluid condensing in the strong field region. The system polarization exhibits a strong field dependence due to the fluid condensation.

description: This scoping review aims to map what is known about non-take-up of the Government of India's social protection schemes delivered through direct benefit transfer and to synthesize the available knowledge. Globally and in India, social protection programmes are vital mechanisms to protect people from poverty, vulnerability and social exclusion throughout life, thus contributing to key social determinants of health. However, social protection benefits often do not reach target beneficiaries, a phenomenon known as "non-take-up." This scoping review will provide information to researchers, policymakers, and implementers on how social protection programs have been implemented in India and on implementation challenges encountered.
Die Zunahme intraanueller Zuwachsstreifen bei Muscheln im Laufe der Erdgeschichte

description: Die Deutung der stärkeren Wachstumsunterbrechungen auf den Schalen von Muscheln als "Jahresringe" wird weiter unterbaut. Bei langlebigen Arten wird daraus ein Rhythmus nachgewiesen, der an den 11-jährigen Sonnenfleckenrhythmus erinnert. Die kleineren intraannuellen Wachstumsstörungen ("Monatsringe?") werden in ihrer durchschnittlichen jährlichen Häufigkeit vom Silur bis zur Gegenwart verfolgt. Es wird eine allmähliche Zunahme im Verlauf der Erdgeschichte festgestellt. Dabei ergeben sich kleinere Sprünge zwischen Karbon und Perm sowie zwischen Trias und Jura. Ein größerer Sprung ist zwischen Jura und Kreide erkennbar. Im Palaeozän gleichen die Zahlen noch sehr denen der Kreide, während vom Eozän ab wieder eine dann gleichbleibende Zunahme sichtbar ist. Die intraannuellen Zuwachsunterbrechungen ("Monatsringe") dürften in der Mehrzahl nicht durch Milieueinflüsse entstanden sein. Zu ihren Ursachen könnten vielleicht Beziehungen zur Kurve der Beschleunigung des erdgeschichtlichen Ablaufes oder jener der Erdexpansion hinführen. Auch die "Monatsringe" lassen unter der Lupe noch kleinere Wachstumsunterbrechungen erkennen, bei denen am ehesten noch örtliche Milieubedingungen mitgewirkt haben könnten.
