description: Using the PIONIER visitor instrument that combines the light of the four Auxiliary Telescopes of ESO's Very Large Telescope Interferometer, we measure precisely the diameters of several symbiotic and related stars: HD 352, HD 190658, V1261 Ori, ER Del, FG Ser, and AG Peg. These diameters - in the range of 0.6 to 2.3 milli-arcseconds - are used to assess the filling factor of the Roche lobe of the mass-losing giants and provide indications on the nature of the ongoing mass transfer. We also provide the first spectroscopic orbit of ER Del, based on CORAVEL and HERMES/Mercator observations. The system is found to have an eccentric orbit with a period of 5.7 years. In the case of the symbiotic star FG Ser, we find that the diameter is changing by 13% over the course of 41 days, while the observations of HD 352 are indicative of an elongation. Both these stars are found to have a Roche filling factor close to 1, as is most likely the case for HD 190658 as well, while the three other stars have factors below 0.5-0.6. Our observations reveal the power of interferometry for the study of interacting binary stars - the main limitation in our conclusions being the poorly known distances of the objects.

Year: 2023

description: Deliverable 7 is the main outcome of WP6 (Repository Setup). It aimed to ensure the accessibility of the generated semantic research data as open data. Its purpose is to produce, as a minimal viable product, a space for accessing and downloading the semantic data within the context and the timeframe of the project in a way that will allow researchers to make use of the semantic output for their own research ends. For the context of the project itself, a triple store was set up for testing and manipulating the produced RDF collaboratively with the Census project team. We have established a SparQL endpoint employing Apache Jena Fuseki 4.5.0 on a remote server. The Census triple store can then be accessed and queried here. A list of basic SparQL queries has been created to help the researcher to develop more complex research agendas. The long-term triple store using the same repository will be installed locally by members of the HU to serve as a SparQL endpoint after the end of the project.

description: This paper is concerned with a certain aspect of the spectral theory of unitary operators in a Hilbert space and its aim is to give an explicit construction of continuous functions of unitary operators. Starting from a given unitary operator we give a family of sequences of trigonometric polynomials converging weakly to the complex measures which allow us to define functions of the operator.

description: Among highly irradiated exoplanets, some have been found to undergo significant hydrodynamic expansion traced by atmospheric escape. To better understand these processes in the context of planetary evolution, we propose NIGHT (the Near-Infrared Gatherer of Helium Transits). NIGHT is a high-resolution spectrograph dedicated to surveying and temporally monitoring He I triplet absorption at 1083nm in stellar and planetary atmospheres. In this paper, we outline our scientific objectives, requirements, and cost-efficient design. Our simulations, based on previous detections and modelling using the current exoplanet population, determine our requirements and survey targets. With a spectral resolution of 70,000 on a 2-meter telescope, NIGHT can accurately resolve the helium triplet and detect 1% peak absorption in 118 known exoplanets in a single transit. Additionally, it can search for three-sigma temporal variations of 0.4% in 66 exoplanets in-between two transits. These are conservative estimates considering the ongoing detections of transiting planets amenable to atmospheric characterisation. We find that instrumental stability at 40m/s, less stringent than for radial velocity monitoring, is sufficient for transmission spectroscopy in He I. As such, NIGHT can utilize mostly off-the-shelf components, ensuring cost-efficiency. A fibre-fed system allows for flexibility as a visitor instrument on a variety of telescopes, making it ideal for follow-up observations after JWST or ground-based detections. Over a few years of surveying, NIGHT could offer detailed insights into the mechanisms shaping the hot Neptune desert and close-in planet population by significantly expanding the statistical sample of planets with known evaporating atmospheres. First light is expected in 2024.

description: Single layer graphene foils produced by Chemical Vapor Deposition (CVD) are rolled with self-positioned layers of InGaAs/Cr forming compact multi-turn tubular structures that consist on successive graphene/metal/semiconductor heterojunctions on a radial superlattice. Using elasticity theory and Raman spectroscopy we show that it is possible to produce homogeneously curved graphene with curvature radius on the 600nm-1200nm range. Additionally, the study of tubular structures also allows the extraction of values for the elastic constants of graphene that are in excellent agreement with elastic constants found in the literature. However, our process has the advantage of leading to a well-defined and nonlocal curvature. Since our curvature radius lie in a range between the large radius studied using mechanical bending and the reduced radius induced by Atomic Force Microscopy experiments we can figure out whether bending effects can be a majoritary driving force for modifications in graphene electronic status. From the results described in this work one can assume that curvature effects solely do not modify the Raman signature of graphene and that strain phenomena observed previously can be ascribed to stretching due to the formation of local atomic bonds. This implies that the interactions of graphene with additional materials on heterostructures must be investigated in detail prior to the development of applications and devices.

Studies on the Role of Solar Ultraviolet Radiation in "Natural" Water Purification by Aquatic Ecosystems

description: Abstract:
The possibility that pollution might deplete the stratospheric ozone layer and intensify solar UV at the earth's surface focuses attention on the role of solar UV in the various ecosystems at the earth's surface. Previous studies suggested that solar UV might contribute to bacterial die off in wastewater and the studies reported here were directed toward elucidating the action of solar UV in "natural" waters.
It has been assumed that solar UV action on aquatic ecosystems can be evaluated (using proper models) on the basis of the following four independently measurable quantities: I) the intensity of solar UV at the water surface, 2) the attenuation of the UV in the water column, 3) the position of the critical organisms in the water, and 4) the sensitivity of the individual organisms to solar UV exposure. These four factors have been investigated on a continuing basis and the results of measurements have been utilized along with special field and laboratory experiments to assess UV-B actions.
Field work has focused on the succession of organisms, their locations in the water column, a,d under more controlled conditions, the killing of E. coli by natural sunlight. Laboratory work has included studies of UV-B lethality, its ability to stimulate positioning responses, and its depression of the photosynthetic activity of algae. Laboratory and field observations have been interpreted through models and our results are consistent with the hypothesis that solar UV is a significant agent for the aquatic microorganisms we have tested.

description: Abstract:
This is a case study of a group organized to resist the construction of an Army Corps of Engineers reservoir project located in Eastern Kentucky, More specifically the account describes how a group of landowners organized themselves and enacted an increasingly complex strategy of resistance. Within this framework perceived costs, leadership and authority and group organization are considered.
The primary method employed in this research was that of repeated interviews with members of the resistance organization who were identified as key informants. These interviews were carried out on both structured and unstructured bases.
The formal analysis of the voluntary association data emphasizes the process of resistance, That is, the report depicts the evolution of persisting resistance organization. The conclusions include recommendations to both project resisters and project planners.

description: We have investigated the structural and electronic properties of phosphorescent planar platinum(II) complexes at the interface of Au(111) with submolecular resolution using combined scanning tunneling microscopy and spectroscopy as well as density functional theory. Our analysis shows that molecule-substrate coupling and lateral intermolecular interactions are weak. While the ligand orbitals remain essentially unchanged upon contact to the substrate, we found modified electronic behavior at the Pt atom due to local hybridization and charge transfer to the substrate. Thus, this novel class of phosphorescent molecules exhibits well-defined and tunable interaction with its local environment.

description: This volume is the result of the international workshop “Affects and Community-Formation in the Petrarchan World”, which was hosted online by the Italienzentrum della Freie Universität Berlin on March 11-12, 2021. The workshop was held by the generous support of the Cluster of Excellence Temporal Communities: Doing Literature in a Global Perspective (Deutsche Forschungsgemeinschaft, EXC 2020 – Project ID 3900608380) as well as that of the Italienzentrum della Freie Universität Berlin. The workshop and the articles presented here all form part of the project “Petrarchan Worlds”, directed by Bernhard Huss in Research Area 1, “Competing Communities”, of the above-mentioned Cluster of Excellence. The workshop focused on the study of Petrarchan “affects”. These “affects”, passions”, or “emotions” are omnipresent in Petrarch’s writings. In addition to feelings of love so frequently expressed in his work, other emotions – sorrow, compassion, anger, envy, for example – are also represented and these too play a crucial role in his interactions with friends, patrons, favorite authors, and readers. Analyzing Petrarch's complex engagements with those "affects" in both his Latin and vernacular works, the essays in this volume explore the different types of emotional, intellectual, and political communities that his writings helped forge.

description: The large phase shift of strongly nonlocal spatial optical soliton(SNSOS) in the (1+1)-dimensional [(1+1)D] lead glass is investigated using the perturbation method. The fundamental soliton solution of the nonlocal nonlinear Schodinger equation(NNLSE) under the second approximation in strongly nonlocal case is obtained. It is found that the phase shift rate along the propagation direction of such soliton is proportional to the degree of nonlocality, which indicates that one can realize Pi-phase-shift within one Rayleigh distance in (1+1)D lead glass. A full comprehension of the nonlocality-enhancement to the phase shift rate of SNSOS is reached via quantitative comparisons of phase shift rates in different nonlocal systems.

We also treat the triviality of them. The basic phenomenon is similar to the complex case but more complicated here.

description: Das vorliegende Working Paper ist der ‚Aktualitätsepik‘ im Frankreich der Religionskriege gewidmet. Dabei handelt es sich um Epen in französischer und lateinischer Sprache, die eine aus ihrer Sicht zeithistorische Thematik verarbeiten. Die Forschungsliteratur betrachtete die Aktualitätsepik gemeinhin als ein ästhetisch minderwertiges und literarhistorisch unbedeutendes Phänomen, das grundlegenden Konventionen der Gattung zuwiderlaufen würde. Das Working Paper zeigt demgegenüber die Virulenz und Persistenz dieses Phänomens auf, indem erstens der Forschungsdiskurs auf seine modernistischen Grundannahmen (Epos ≠ Aktualität/Moderne) hin überprüft und kritisch hinterfragt wird, zweitens auf die seit der Antike wirkmächtige Tradition von Epen mit (zeit-)historischer Thematik eingegangen wird und drittens die Aktualitätsepik im Frankreich der Religionskriege konkret in den Blick genommen wird. In diesem Zusammenhang interessieren besonders Strategien der Episierung vor dem Hintergrund diverser Modelltexte der Gattungstradition sowie die multitemporale Vielschichtigkeit und die ideologische Funktionalisierung des epischen Formulariums bei den französischen Epikern.

In particular, we prove that their Julia sets can never be a Sierpiński carpet if the parameter is real. We show that the Julia set is a quasicircle if and only if the parameter lies in the unbounded capture domain of these models. Moreover, the asymptotic formula of the Hausdorff dimension of the Julia set is calculated as the parameter tends to infinity.

description: Among the distance based algorithms in phylogenetic tree reconstruction, the neighbor-joining algorithm has been a widely used and effective method. We propose a new algorithm which counts the number of consistent quartets for cherry picking with tie breaking. We show that the success rate of the new algorithm is almost equal to that of neighbor-joining. This gives an explanation of the qualitative nature of neighbor-joining and that of dissimilarity maps from DNA sequence data. Moreover, the new algorithm always reconstructs correct trees from quartet consistent dissimilarity maps.

description: This article offers a reappraisal of Fung's method for quasilinear viscoelasticity. It is shown that a number of negative features exhibited in other works, commonly attributed to the Fung approach, are merely a consequence of the way it has been applied. The approach outlined herein is shown to yield improved behaviour, and offers a straightforward scheme for solving a wide range of models. Results from the new model are contrasted with those in the literature for the case of uniaxial elongation of a bar: for an imposed stretch of an incompressible bar, and for an imposed load. In the last case, a numerical solution to a Volterra integral equation is required to obtain the results. This is achieved by a high order discretisation scheme. Finally, the stretch of a compressible viscoelastic bar is determined for two distinct materials: Horgan-Murphy and Gent.

description: The Mitchell Spectrograph (a.k.a. VIRUS-P) on the 2.7m Harlan J. Smith telescope at McDonald Observatory is currently the largest field of view (FOV) integral field unit (IFU) spectrograph in the world (1.7'x1.7'). It was designed as a prototype for the highly replicable VIRUS spectrograph which consists of a mosaic of IFUs spread over a 16' diameter FOV feeding 150 spectrographs similar to the Mitchell. VIRUS will be deployed on the 9.2 meter Hobby-Eberly Telescope (HET) and will be used to conduct the HET Dark Energy Experiment (HETDEX). Since seeing first light in 2007 the Mitchell Spectrograph has been widely used, among other things, to study nearby galaxies in the local universe where their internal structure and the spatial distribution of different physical parameters can be studied in great detail. These observations have provided important insight into many aspects of the physics behind the formation and evolution of galaxies and have boosted the scientific impact of the 2.7 meter telescope enormously. Here I review the contributions of the Mitchell Spectrograph to the study of nearby galaxies, from the investigation of the spatial distribution of dark matter and the properties of supermassive black holes, to the studies of the process of star formation and the chemical composition of stars and gas in the ISM, which provide important information regarding the formation and evolution of these systems. I highlight the fact that wide field integral field spectrographs on small and medium size telescopes can be powerful cost effective tools to study the astrophysics of galaxies. Finally I briefly discuss the potential of HETDEX for conducting studies on nearby galaxies. The survey parameters make it complimentary and competitive to ongoing and future surveys like SAMI and MANGA.

description: Auns. The aim of our paper is to investigate the low-amplitude and long-period variations in evolved stars with a precise radial velocity (RV) survey. Methods. The high-resolution, the fiber-fed Bohyunsan Observatory Echelle Spectrograph (BOES) was used from 2003 to 2013 for a radial velocity survey of giant stars as part of the exoplanet search program at Bohyunsan Optical Astronomy Observatory (BOAO). Results. We report the detection of three new planetary companions orbiting the K giants beta Cnc, mu Leo, and beta UMi. The planetary nature of the radial velocity variations is supported by analyzes of ancillary data. The HIPPARCOS photometry shows no variations with periods close to those in RV variations and there is no strong correlation between the bisector velocity span (BVS) and the radial velocities for each star. Furthermore, the stars show weak or no core reversal in Ca II H lines indicating that they are inactive stars. The companion to beta Cnc has a minimum mass of 7.8 M_Jup in a 605-day orbit with an eccentricity of 0.08. The giant mu Leo is orbited by a companion of minimum mass of 2.4 M_Jup having a period of 357 days and an eccentricity of 0.09. The giant beta UMi is a known barium star and is suspected of harboring a white dwarf or substellar mass companion. Its companion has a minimum mass of 6.1 M_Jup, a period of 522 days, and an eccentricity e = 0.19.

A Refinement of the Schrödinger Equation Involving Dissipation of Waves in the Phase Space

description: We give an example of a mathematical model describing quantum mechanical processes interacting with medium. As a model, we consider the process of heat scattering of a wave function defined on the phase space. We consider the case when the heat diffusion takes place only with respect to momenta. We state and study the corresponding modified Kramers equation for this process. We consider the consequent approximations to this equation in powers of the quantity inverse to the medium resistance per unit of mass of the particle in the process. The approximations are constructed similarly to statistical physics, where from the usual Kramers equation for the evolution of probability density of the Brownian motion of a particle in the phase space, one deduces an approximate description of this process by the Fokker--Planck equation for the density of probability distribution in the configuration space. We prove that the zero (invertible) approximation to our model with respect to the large parameter of the medium resistance, yields the usual quantum mechanical description by the Schrödinger equation with the standard Hamilton operator. We deduce the next approximation to the model with respect to the negative power of the medium resistance coefficient. As a result we obtain the modified Schrödinger equation taking into account dissipation of the process in the initial model.

Exactly solvable model of stochastic heat engine: Optimization of power, its fluctuations and efficiency
Creators: name: Holubec, Viktor
Publisher: name: arXiv
Year: 2014
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: We investigate a stochastic heat engine based on an over-damped particle diffusing on the positive real axis in an externally driven time-periodic log-harmonic potential. The periodic driving is composed of two isothermal and two adiabatic branches. Within our specific setting we verify the recent universal results regarding efficiency at maximum power and discuss properties of the optimal protocol. Namely, we show that for certain fixed parameters the optimal protocol maximizes not only the output power but also the efficiency. Moreover, we calculate the variance of the output work and discuss the possibility to minimize fluctuations of the output power.

Effects of Li doping on H-diffusion in MgH$_2$: a first-principles study

description: The effects of Li doping in MgH$_2$ on H-diffusion process are investigated, using first-principles calculations. We have identified two key effects: (1) The concentration of H vacancy in the $+1$ charge state (V$_H^{+1}$) can increase by several orders of magnitude upon Li doping, which significantly increases the vacancy mediated H diffusion rate. It is caused by the preferred charge states of substitutional Li in the $-1$ state (Li$_{Mg}^{-1}$) and of interstitial Li in the $+1$ state (Li$_i^{+1}$), which indirectly reduce the formation energy of V$_H^{+1}$ by up to 0.39 eV depending on the position of Fermi energy. (2) The interaction between V$_H^{+1}$ and Li$_{Mg}^{-1}$ is found to be attractive with a binding energy of 0.55 eV, which immobilizes the V$_H^{+1}$ next to Li$_{Mg}^{-1}$ at high Li doping concentration. As a result, the competition between these two effects leads to large enhancement of H diffusion at low Li doping concentration due to the increased H-vacancy concentration, but only limited enhancement at high Li concentration due to the immobilization of H vacancies by too many Li.
Deliverable 2 - Documented Semantic Data Model
Creators: name: Nenova, Denitsa

Publisher: name: Zenodo
Year: 2023

description: This deliverable entailed creating an explicit semantic reference data model for the Census data and relevant art historical data more generally. Using CIDOC CRM and its extensions as well as the SARI Semantic Reference Data Model modeling strategy, this deliverable created a robust documentation of a full semantic reference data model for the Census project. The result is the Semantic Census Data Models. The Census Semantic Data Models (CSDM) represent a coherent set of semantically-encoded data models for the use of art historians in the (re-)representation of art historical data related to the history of monuments, the documents that respond to or bear witness to them, the people or places that relate to these objects of study through historical events, and the images and bibliography which reference them.

Ab initio quasiparticle bandstructure of ABA and ABC-stacked graphene trilayers

description: We obtain the quasiparticle band structure of ABA and ABC-stacked graphene trilayers through ab initio density functional theory (DFT) and many-body quasiparticle calculations within the GW approximation. To interpret our results, we fit the DFT and GW $π$ bands to a low energy tight-binding model, which is found to reproduce very well the observed features near the K point. The values of the extracted hopping parameters are reported and compared with available theoretical and experimental data. For both stackings, the self energy corrections lead to a renormalization of the Fermi velocity, an effect also observed in previous calculations on monolayer graphene. They also increase the separation between the higher energy bands, which is proportional to the nearest neighbor interlayer hopping parameter $γ_1$. Both features are brought to closer agreement with experiment through the self energy corrections. Finally, other effects, such as trigonal warping, electron-hole asymmetry and energy gaps are discussed in terms of the associated parameters.

description: We construct general anisotropic cosmological scenarios governed by an $f(R)=R^n$ gravitational sector. Focusing then on some specific geometries, and modelling the matter content as a perfect fluid, we perform a phase-space analysis. We analyze the possibility of accelerating expansion at late times, and additionally, we determine conditions for the parameter $n$ for the existence of phantom behavior, contracting solutions as well as of cyclic cosmology. Furthermore, we analyze if the universe evolves towards the future isotropization without relying on a cosmic no-hair theorem. Our results indicate that anisotropic geometries in modified gravitational frameworks present radically different cosmological behaviors compared to the simple isotropic scenarios.

The various field and data recipes have been regularly discussed and eventually submitted to Programmfabrik for implementation. The completion of this stage was essential for the full development, implementation, and testing of the ETL pipeline in the following WP4 (ETL Pipeline Development).
Nondecaying linear and nonlinear modes in a periodic array of spatially localized dissipations

description: We demonstrate the existence of extremely weakly decaying linear and nonlinear modes (i.e. modes immune to dissipation) in the one-dimensional periodic array of identical spatially localized dissipations, where the dissipation width is much smaller than the period of the array. We consider wave propagation governed by the one-dimensional Schrödinger equation in the array of identical Gaussian-shaped dissipations with three parameters, the integral dissipation strength $Γ_0$, the width $σ$ and the array period $d$. In the linear case, setting $σ\to0$, while keeping $Γ_0$ fixed, we get an array of zero-width dissipations given by the Dirac delta-functions, i.e. the complex Kroning-Penney model, where an infinite number of nondecaying modes appear with the Bloch index being either at the center, $k= 0$, or at the boundary, $k= π/d $, of an analog of the Brillouin zone. By using numerical simulations we confirm that the weakly decaying modes persist for $σ$ such that $σ/d\ll1$ and have the same Bloch index. The nondecaying modes persist also if a real-valued periodic potential is added to the spatially periodic array of dissipations, with the period of the dissipative array being multiple of that of the periodic potential. We also consider evolution of the soliton-shaped pulses in the nonlinear Schrödinger equation with the spatially periodic dissipative lattice and find that when the pulse width is much larger than the lattice period and its wave number $k$ is either at the center, $k= 2π/d$, or at the boundary, $k= π/d $, a significant fraction of the pulse escapes the dissipation forming a stationary nonlinear mode with the soliton shaped envelope and the Fourier spectrum consisting of two peaks centered at $k $ and $-k$.
