description: In this work the collapsing process of a spherically symmetric star, made of dust cloud, in the background of dark energy is studied for two different gravity theories separately, i.e., DGP Brane gravity and Loop Quantum gravity. Two types of dark energy fluids, namely, Modified Chaplygin gas and Generalised Cosmic Chaplygin gas are considered for each model. Graphs are drawn to characterize the nature and the probable outcome of gravitational collapse. A comparative study is done between the collapsing process in the two different gravity theories. It is found that in case of dark matter, there is a great possibility of collapse and consequent formation of Black hole. In case of dark energy possibility of collapse is far lesser compared to the other cases, due to the large negative pressure of dark energy component. There is an increase in mass of the cloud in case of dark matter collapse due to matter accumulation. The mass decreases considerably in case of dark energy due to dark energy accretion on the cloud. In case of collapse with a combination of dark energy and dark matter, it is found that in the absence of interaction there is a far better possibility of formation of black hole in DGP brane model compared to Loop quantum cosmology model.

description: Timing aspects in formalisms with explicit resources and parallelism are investigated, and it is presented a formal link between timed membrane systems and timed Petri nets with localities. For both formalisms, timing does not increase the expressive power; however both timed membrane systems and timed Petri nets are more flexible in describing molecular phenomena where time is a critical resource. We establish a link between timed membrane systems and timed Petri nets with localities, and prove an operational correspondence between them.

Asymptotic expansions of the solutions of the Cauchy problem for nonlinear parabolic equations

description: Let $u$ be a solution of the Cauchy problem for the nonlinear parabolic equation $$ \partial_t u=Δu+F(x,t,u,\nabla u) \quad in \quad{\bf R}^N\times(0,\infty), \quad u(x,0)=φ(x)\quad in \quad{\bf R}^N, $$ and assume that the solution $u$ behaves like the Gauss kernel as $t\to\infty$. In this paper, under suitable assumptions of the reaction term $F$ and the initial function $φ$, we establish the method of obtaining higher order asymptotic expansions of the solution $u$ as $t\to\infty$. This paper is a generalization of our previous paper, and our arguments are applicable to the large class of nonlinear parabolic equations.

description: We present a finite difference method to solve a new type of nonlocal hydrodynamic equations that arise in the theory of spatially inhomogeneous Bloch oscillations in semiconductor superlattices. The hydrodynamic equations describe the evolution of the electron density, electric field and the complex amplitude of the Bloch oscillations for the electron current density and the mean energy density. These equations contain averages over the Bloch phase which are integrals of the unknown electric field and are derived by singular perturbation methods. Among the solutions of the hydrodynamic equations, at a 70 K lattice temperature, there are spatially inhomogeneous Bloch oscillations coexisting with moving electric field domains and Gunn-type oscillations of the current. At higher temperature (300 K) only Bloch oscillations remain. These novel solutions are found for restitution coefficients in a narrow interval below their critical values and disappear for larger values. We use an efficient numerical method based on an implicit second-order finite difference scheme for both the electric field equation (of drift-diffusion type) and the parabolic equation for the complex amplitude. Double integrals appearing in the nonlocal hydrodynamic equations are calculated by means of expansions in modified Bessel functions. We use numerical simulations to ascertain the convergence of the method. If the complex amplitude equation is solved using a first order scheme for restitution coefficients near their critical values, a spurious convection arises that annihilates the complex amplitude in the part of the superlattice that is closer to the cathode. This numerical artifact disappears if the space step is appropriately reduced or we use the second-order numerical scheme.

description: Social media, such as blogs, are often seen as democratic entities that allow more voices to be heard than the conventional mass or elite media. Some also feel that social media exhibits a balancing force against the arguably slanted elite media. A systematic comparison between social and mainstream media is necessary but challenging due to the scale and dynamic nature of modern communication. Here we propose empirical measures to quantify the extent and dynamics of social (blog) and mainstream (news) media bias. We focus on a particular form of bias---coverage quantity---as applied to stories about the 111th US Congress. We compare observed coverage of Members of Congress against a null model of unbiased coverage, testing for biases with respect to political party, popular front runners, regions of the country, and more. Our measures suggest distinct characteristics in news and blog media. A simple generative model, in agreement with data, reveals differences in the process of coverage selection between the two media.

Dynamics of helical vortices and helical-vortex rings

Subjects: subject: Other Condensed Matter (cond-mat.other)

description: The Letter considers dynamics of helical vortices and helical-vortex rings either solving directly the equations of motions of a vortex line or using canonical relations following from the Hamiltonian equations of motion. An analytical solution in elliptical integrals was found for helical-vortex rings in the local-induction approximation. The analysis based on the canonical Hamilton relation provides a clear physical explanation for anomalous velocities of helical-vortex rings, i.e., for suppression of the velocity and even inversion of its direction at sufficiently large amplitude of the helical distortion. The extended local-induction approximation is suggested, which provides an exact solution for the equations of motion of helical vortices and helical-vortex rings in the limit when the small-pitch helical vortex reduces to a cylindric sheet of uniform vorticity.

Согласно исследованию, клинические проявления тазового пролапса значительно снижают качество жизни (в среднем на 55,0 ± 10,8%). При этом симптомы нарушения мочеиспускания имеют наиболее выраженное отрицательное влияние на качество жизни данной категории больных. Хирургическая коррекция тазового пролапса осуществлялась с помощью сетчатых имплантов «Пелвикс» и «Урослинг-1» («Линтекс», Россия), Prolift™ (Johnson & Johnson Company, США). Оценка результатов лечения проведена в срок от 3 до 12 месяцев после операции. Для сравнительной оценки качества жизни был использован валидизированный специфический опросник в отношении дисфункции тазовых органов (Pelvic Floor Distress Inventory-20). Проведённый анализ достоверно показал улучшение качества жизни больных с пролапсом тазовых органов после протезирующей реконструкции интравагинальным доступом с использованием сетчатых имплантов на 43,1%.

B(E2) transition rates have been calculated and compared to experimental data. Overall good agreement is obtained for transitions within the ground state band, while some interband transitions appear to be systematically underpredicted in gamma-unstable nuclei and overpredicted in rotational nuclei.

description: Es wurden beta-annealed Zustände mit großer und kleiner Korngröße sowie bi-modale Zustände mit kleiner Korngröße der hochfesten metastabilen beta-Titanlegierung Ti-5Al-5V-5Mo-3Cr mit je mindestens drei Festigkeitsniveaus hergestellt. Es wurden mechanische Kennwerte (u.a. sigma(0.2), A_5, sigma(HCF) und K(IC)), deren Mikrostruktur und Bruchflächen dieser Zustände bis zu sehr hohen Dehngrenzen von bis zu 1900 MPa miteinander verglichen. Durch Variation von Umformung und Glühtemperatur der Rekristallisation kann einerseits die Korngröße und dadurch die Brucheigenschaften beeinflusst werden. Andererseits ist es davon unabhängig möglich Anteil und Größe der alpha-Titanausscheidungen durch die Auslagerung zu definieren, was die Festigkeit bestimmt. Die Relationen der mechanischen Eigenschaften ändern sich bei Dehngrenzen über ca. 1400 MPa, da hier der Festigkeitsunterschied von dem Korninneren zu den ausscheidungsfreien Zonen der Korngrenzen einen großen Einfluss hat.
description: beta-annealed conditions with small and big grainsizes and bi-modal conditions with a small grainsize were made of the metastable beta-titanium alloy Ti-5Al-5V-5Mo-3Cr, each with three or more strengthlevels. Mechanical properties (like sigma(0.2), A_5, sigma(HCF) and K(IC)), microstructures and fractured surfaces of conditions with yield strength up to 1900 MPa were compared. Grainsize and fracture properties could be affected by a variation of deformation and annealing temperatures. Independently from that, volume and size of alpha-titanium-precipitates are defined by aging, which sets the strength. The relations between mechanical properties are changing at strengthlevels above 1350 - 1400 MPa, caused by a great influence of the difference in strength between grain and precipitation-free-zone.

description: Колоректальный рак характеризуется наиболее частой локализацией среди всех онкологических заболеваний как в России, так и во всем мире. В последние годы наблюдается стабильная динамика большого количества выявленных случаев заболеваний злокачественными новообразованиями толстого кишечника. В данной статье рассмотрены основные вопросы канцерогенеза злокачественных новообразований толстого кишечника, их морфологии и эпидемиологии на примере Новгородской области. Было установлено, что большое количество случаев в общей структуре заболеваемости приходится на аденокарциному БДУ, а чаще всего новые случаи развития опухолей обнаруживаются в возрасте 60–70 лет, что говорит об особом риске для взрослого населения. Принимая во внимание зависимость заболеваемости от внешних факторов окружающей среды и образа жизни человека, данная тема актуальна с точки зрения возможности осуществления эффективной профилактики и скрининга колоректального рака с целью диагностики и лечения предраковых заболеваний толстой кишки.

description: The mission of the 1+MG initiative, declared in 2018 by 26 signatory countries, is to make >1 million whole genome sequences (WGS) accessible for use in research, health care, and prevention. A 1+MG working group, Genome of Europe (GoE), started in 2019 to establish a European Reference Genome Database of >500k WGS. The rationale for creating GoE is to have a large, Europe-wide collection of subgroup-specific reference genomes (with minimal phenotype data). These can be used: a) to analyze genetic diversity across European populations, b) to interpret potentially clinical/pathogenic genetic variants in comparison to disease-specific genomes, c) to recalibrate genetic risk profiles to ancestral backgrounds, d) as a reference panel for imputations in lower resolution but larger scale array genotyping efforts.We here present the preparatory steps to start creating such a database.
Temperature dependence of the electron spin $\textbf{g}$ factor in CdTe and InP

description: Temperature dependence of the electron spin $g$ factors in bulk CdTe and InP are calculated and compared with experiment. It is assumed that the only modification of the band structure related to temperature is a dilatation change in the fundamental energy gap. The dilatation changes of fundamental gaps are calculated for both materials using available experimental data. Computations of the band structures in the presence of a magnetic field are carried out employing five-level {\Pp} model appropriate for medium-gap semiconductors. In particular, the model takes into account spin splitting due to bulk inversion asymmetry (BIA) of the materials. The resulting theoretical effective masses and $g$ factors increase with electron energy due to band nonparabolicity. Average $g$ values are calculated summing over populated Landau and spin levels properly accounting for the thermal distribution of electrons in the band. It is shown that the spin splitting due to BIA in the presence of magnetic field gives observable contributions to $g$ values. Our calculations are in good agreement with experiment in the temperature range of 0 K to 300 K for CdTe and 0 K to 180 K for InP. The temperature dependence of $g$ is stronger in CdTe than in InP due to different signs of the band-edge $g$ values in the two materials. Good agreement between the theory and experiment strongly indicates that the temperature dependence of spin $g$ factors is correctly explained. In addition, we discuss formulas for the energy dependence of spin $g$ factor due to band nonparabolicity, which are liable to misinterpretation.

description: Single surface plasmon polaritons are excited using photons generated via spontaneous parametric down-conversion. The mean excitation rates, intensity correlations and Fock state populations are studied. The observed dependence of the second order coherence in our experiment is consistent with a linear uncorrelated Markovian environment in the quantum regime. Our results provide important information about the effect of loss for assessing the potential of plasmonic waveguides for future nanophotonic circuitry in the quantum regime.

description: We introduce a notion of real-valued reward testing for probabilistic processes by extending the traditional nonnegative-reward testing with negative rewards. In this richer testing framework, the may and must preorders turn out to be inverses. We show that for convergent processes with finitely many states and transitions, but not in the presence of divergence, the real-reward must-testing preorder coincides with the nonnegative-reward must-testing preorder. To prove this coincidence we characterise the usual resolution-based testing in terms of the weak transitions of processes, without having to involve policies, adversaries, schedulers, resolutions, or similar structures that are external to the process under investigation. This requires establishing the continuity of our function for calculating testing outcomes.

The effect of annealing time and different dopants on the transport properties of the BaxK1-xFe2As2 tapes were systematically studied. By co-doping with Ag and Pb, the transport critical current density Jc of BaxK1-xFe2As2 tapes was significantly improved in whole field region and the highest transport Jc was up to 1.4x10^4 A/cm^2 (Ic=100 A) at 4.2K in self field. It is proposed that the superior Jc in the co-doped samples are due to the combine effect of Pb doping at low fields and Ag doping at high fields.

description: Extensions of the Standard Model that contain leptophobic Z' gauge bosons are theoretically interesting but difficult to probe directly in high-energy hadron colliders. However, precision measurements of Standard Model neutral current processes can provide powerful indirect tests. We demonstrate that parity-violating deep inelastic scattering of polarized electrons off of deuterium offer a unique probe leptophobic Z' bosons with axial quark couplings and masses above 100 GeV. In addition to covering a wide range of previously uncharted parameter space, planned measurements of the deep inelastic parity-violating eD asymmetry would be capable of testing leptophobic Z' scenarios proposed to explain the CDF W plus di-jet anomaly.

description: Bisectors of the HARPS cross-correlation function (CCF) can discern between planetary radial-velocity (RV) signals and spurious RV signals from stellar magnetic activity variations. However, little is known about the effects of the stellar atmosphere on CCF bisectors or how these effects vary with spectral type and luminosity class. Here we investigate the variations in the shapes of HARPS CCF bisectors across the HR diagram in order to relate these to the basic stellar parameters, surface gravity and temperature. We use archive spectra of 67 well studied stars observed with HARPS and extract mean CCF bisectors. We derive previously defined bisector measures (BIS, v_bot, c_b) and we define and derive a new measure called the CCF Bisector Span (CBS) from the minimum radius of curvature on direct fits to the CCF bisector. We show that the bisector measures correlate differently, and non-linearly with log g and T_eff. The resulting correlations allow for the estimation of log g and T_eff from the bisector measures. We compare our results with 3D stellar atmosphere models and show that we can reproduce the shape of the CCF bisector for the Sun.

description: A new scheme for computing dynamical evolutions and gravitational radiations for intermediate-mass-ratio inspirals (IMRIs) based on an effective one-body (EOB) dynamics plus Teukolsky perturbation theory is built in this paper. In the EOB framework, the dynamics essentially affects the resulted gravitational waveform for binary compact star system. This dynamics includes two parts. One is the conservative part which comes from effective one-body reduction. The other part is the gravitational back reaction which contributes to the shrinking process of the inspiral of binary compact star system. Previous works used analytical waveform to construct this back reaction term. Since the analytical form is based on post-Newtonian expansion, the consistency of this term is always checked by numerical energy flux. Here we directly use numerical energy flux by solving the Teukolsky equation via the frequency-domain method to construct this back reaction term. And the conservative correction to the leading order terms in mass-ratio is included in the deformed-Kerr metric and the EOB Hamiltonian. We try to use this method to simulate not only quasi-circular adiabatic inspiral but also the nonadiabatic plunge phase. For several different spinning black holes, we demonstrate and compare the resulted dynamical evolutions and gravitational waveforms.

description: In these lectures we introduce the functional renormalization group out of equilibrium. While in thermal equilibrium typically a Euclidean formulation is adequate, nonequilibrium properties require real-time descriptions. For quantum systems specified by a given density matrix at initial time, a generating functional for real-time correlation functions can be written down using the Schwinger-Keldysh closed time path. This can be used to construct a nonequilibrium functional renormalization group along similar lines as for Euclidean field theories in thermal equilibrium. Important differences include the absence of a fluctuation-dissipation relation for general out-of-equilibrium situations. The nonequilibrium renormalization group takes on a particularly simple form at a fixed point, where the corresponding scale-invariant system becomes independent of the details of the initial density matrix. We discuss some basic examples, for which we derive a hierarchy of fixed point solutions with increasing complexity from vacuum and thermal equilibrium to nonequilibrium. The latter solutions are then associated to the phenomenon of turbulence in quantum field theory.

A Stochastic Broadcast Pi-Calculus

description: In this paper we propose a stochastic broadcast PI-calculus which can be used to model server-client based systems where synchronization is always governed by only one participant. Therefore, there is no need to determine the joint synchronization rates. We also take immediate transitions into account which is useful to model behaviors with no impact on the temporal properties of a system. Since immediate transitions may introduce non-determinism, we will show how these non-determinism can be resolved, and as result a valid CTMC will be obtained finally. Also some practical examples are given to show the application of this calculus.

description: Angle-resolved photoelectron spectroscopy is used for a detailed study of the electronic structure of the topological insulator Bi2Se3. Nominally stoichiometric and calcium-doped samples were investigated. The pristine surface shows the topological surface state in the bulk band gap. As time passes, the Dirac point moves to higher binding energies, indicating an increasingly strong downward bending of the bands near the surface. This time-dependent band bending is related to a contamination of the surface and can be accelerated by intentionally exposing the surface to carbon monoxide and other species. For a sufficiently strong band bending, additional states appear at the Fermi level. These are interpreted as quantised conduction band states. For large band bendings, these states are found to undergo a strong Rashba splitting. The formation of quantum well states is also observed for the valence band states. Different interpretations of similar data are also discussed.

description: Auch weil George A. Kelly (1986) die im klinischen Anwendungskontext entwickelte Methode der Repertory Grid Technik bereits bei seiner ersten Vorstellung 1955 detailliert und instruktiv beschrieben hat, hat es seitdem eine große Verbreitung gefunden. Hauptanwendungsgebiet ist immer noch der klinische Bereich, wo es auch Eingang in die medizinische Forschung gefunden hat. Ein weiterer Teil der Publikationen ist methodischer oder methodologischer Natur.Der Transfer in andere Bereiche der Psychologie, etwa Arbeitspsychologie, Umweltpsychologie oder auch Management und Organisation erfolgt bisher hingegen nur zögernd. Das mag zum einen daran liegen, dass bisher noch keine breit geteilten Standards für Verfahren der elektronischen Datenaufbereitung und –auswertung vorliegen und man sich weiterhin eher „handgemachter“ Prozeduren und Programme bedient, zum anderen aber auch daran, dass es sich um eine aufwendige Verfahrensweise handelt, die einen dialogischen und interpretativen Forschungsstil in einer überschaubaren und partnerschaftlich organisierten Stichprobe erfordert. Wir können daher annehmen, dass das Verfahren in der Praxis häufig angewendet wird, ohne allerdings Eingang in den wissenschaftlichen Diskurs zu finden. So liegt am Fachbereich Psychologie der Universität Hamburg eine große Anzahl an Diplomarbeiten vor, und es existieren kommerzielle Software-Anwendungen für den Bereich der Organisationsberatung. In dieser Arbeit wird ein Weg vorgestellt, das Verfahren aus der Forschung in die Praxis zu transferieren, ohne dabei Transparenz aufgeben zu müssen. Nicht nur im Bereich der Unternehmenskultur, sondern überall dort, wo es um eine Vermittlung zwischen strategischer Planung und Expertise einerseits und alltäglicher, operativer Anwendung andererseits geht, könnte das Repertory Grid Verfahren als methodische Brücke wichtige Vermittlungsfunktionen übernehmen.
Nucleation and growth of the γ' (AlAg2) precipitate in Al-Ag(-Cu) alloys

description: Precipitation of the γ' (AlAg2) phase was investigated in Al-Ag(-Cu) alloys using high resolution transmission electron microscopy and scanning transmission electron microscopy. Precipitation commenced with segregation of silver to stacking faults, followed by thickening in steps corresponding to single unit cell ledges. In conjunction with gradual segregation of silver and aluminium into ordered layers this yielded γ' phase platelets with a thickness of either 2 or 3x the AlAg2 c-lattice parameter. Plates with a thickness of 2 c(AlAg2) would not achieve self-accommodation of the shape strain for transformation. Further thickening of the precipitates was slow, despite considerable silver segregation around the precipitates. Growth by the addition of single unit cell height ledges is expected to lead to an additional shear strain energy barrier to ledge nucleation and this may contribute to a process of nucleation-limited growth.

description: The nuclear matrix element for the two neutrino double beta decay (DBD) of 136Xe was evaluated by FSQP (Fermi Surface Quasi Particle model), where experimental GT strengths measured by the charge exchange reaction and those by the beta decay rates were used. The 2 neutrino DBD matrix element is given by the sum of products of the single beta matrix elements via low-lying (Fermi Surface) quasi-particle states in the intermediate nucleus. 136Xe is the semi-magic nucleus with the closed neutron-shell, and the beta + transitions are almost blocked. Thus the 2 neutrino DBD is much suppressed. The evaluated 2 neutrino DBD matrix element is consistent with the observed value.

description: Markowitz's celebrated mean--variance portfolio optimization theory assumes that the means and covariances of the underlying asset returns are known. In practice, they are unknown and have to be estimated from historical data. Plugging the estimates into the efficient frontier that assumes known parameters has led to portfolios that may perform poorly and have counter-intuitive asset allocation weights; this has been referred to as the "Markowitz optimization enigma." After reviewing different approaches in the literature to address these difficulties, we explain the root cause of the enigma and propose a new approach to resolve it. Not only is the new approach shown to provide substantial improvements over previous methods, but it also allows flexible modeling to incorporate dynamic features and fundamental analysis of the training sample of historical data, as illustrated in simulation and empirical studies.

description: Finding the ground state of a fermionic Hamiltonian using quantum Monte Carlo is a very difficult problem, due to the Fermi sign problem. While still scaling exponentially, full configuration-interaction Monte Carlo (FCI-QMC) mitigates some of the exponential variance by allowing annihilation of noise -- whenever two walkers arrive at the same configuration with opposite signs, they are removed from the simulation. While FCI-QMC has been quite successful for quantum chemistry problems, its application to problems in condensed systems has been limited. In this paper, we apply FCI-QMC to the Fermi polaron problem, which provides an ideal test-bed for improving the algorithm. In its simplest form, FCI-QMC is unstable for even a fairly small system sizes. However, with a series of algorithmic improvements, we are able to significantly increase its effectiveness. We modify fixed node QMC to work in these systems, introduce a well chosen importance sampled trial wave function, a partial node approximation, and a variant of released node. Finally, we develop a way to perform FCI-QMC directly in the thermodynamic limit.

Klischee im Bild: Bibliothekare und ihre Darstellung in der Kunst
Creators: name: Keilholz, Constanze
Publisher: name: Perspektive Bibliothek
Year: 2019

description: Die Auseinandersetzung mit gängigen gesellschaftlichen Vorstellungen des Bibliothekars/der Bibliothekarin ist vor allem in Fachkreisen ein beliebtes Thema. Verschiedene Stereotype und Klischees wurden von der Forschung erkannt und ihr Vorkommen in Comic, Literatur und Film hinreichend dokumentiert. Allein eine Übersicht der Bibliothekarsdarstellungen in der bildenden Kunst wurde bisher nicht in dem hier vorgelegten Umfang realisiert. Acht Porträts aus sieben Jahrhunderten werden mit Blick auf die in ihnen transportierten Berufsklischees vorgestellt. Dabei liegt der Schwerpunkt auf der Kontextualisierung der Werke. Sowohl die Entwicklung des Berufsstands zur jeweiligen Zeit als auch stilistische Eigenheiten der Künstler haben entscheidenden Einfluss auf die Darstellung der Bibliothekare im Bild genommen. Die Relevanz des Themas liegt in der Persistenz der Motive. Diese zeigt sich etwa darin, dass noch der rezente Wikipedia-Artikel zum Bibliothekar mit Giuseppe Arcimboldos fast 450 Jahre altem Gemälde eines Bücherkopfes illustriert wird. Der Einfluss der vorgestellten Werke auf landläufige Vorstellungen diesen Beruf betreffend kann folglich nicht überschätzt werden. Anstatt die vorgestellten Bibliothekarsbilder erschöpfend zu besprechen, möchte dieser Beitrag einen grundlegenden Impuls für die Auseinandersetzung mit dem Thema geben.

description: "Theorems for Free!" (Wadler, FPCA 1989) is a slogan for a technique that allows to derive statements about functions just from their types. So far, the statements considered have always had a purely extensional flavor: statements relating the value semantics of program expressions, but not statements relating their runtime (or other) cost. Here we study an extension of the technique that allows precisely statements of the latter flavor, by deriving quantitative theorems for free. After developing the theory, we walk through a number of example derivations. Probably none of the statements derived in those simple examples will be particularly surprising to most readers, but what is maybe surprising, and at the very least novel, is that there is a general technique for obtaining such results on a quantitative level in a principled way. Moreover, there is good potential to bring that technique to bear on more complex examples as well. We turn our attention to short-cut fusion (Gill et al., FPCA 1993) in particular.

description: The adsorption of 1,4-benzenediamine (BDA) on the Au(111) surface and azobenzene on the Ag(111) surface is investigated using density functional theory (DFT) with a non-local density functional (vdW-DF) and a semi-local Perdew-Burke-Ernzerhof (PBE) functional. For BDA on Au(111), the inclusion of London dispersion interactions not only dramatically enhances the molecule-substrate binding, resulting in adsorption energies consistent with experimental results, but also significantly alters the BDA binding geometry. For azobenzene on Ag(111), the vdW-DF produces superior adsorption energies compared to those obtained with other dispersion corrected DFT approaches. These results provide evidence for the applicability of the vdW-DF method and serves as a practical benchmark for the investigation of molecules adsorbed on noble metal surfaces.
