Authors: Zippel Claus , Sauer Sebastian , Bohnet-Joschko Sabine , Giesel Frederik L. , Kopka Klaus 
Published: October 2020

Zusammenfassung
Hintergrund In den letzten Jahren werden zunehmend klinische Bildgebungsstudien initiiert. Die zeitnahe Umsetzung der damit verbundenen administrativen Vorgänge wirkt sich positiv auf den Rekrutierungsstart und die Studienkosten aus. Ziel war es, wesentliche Aspekte zum administrativen Management von Bildgebungsstudien zu identifizieren und nutzbar zu machen.
Methodik Hierfür wurde beispielhaft das Setup der prospektiv-nuklearmedizinischen Prüfung „[68Ga]Ga-PSMA-11 bei Hochrisiko-Prostatakrebs“ fokussiert. Durch qualitativ-explorative Interviews mit Verwaltungsexperten und der Studienleitung konnten administrative Aspekte und Kriterien, die für den Studienstart wesentlich waren, retrospektiv erhoben und mittels gängiger Prozessmanagementmethoden aufbereitet werden.
Ergebnisse Für die Teilprozesse (i) Beschaffung von Studienmaterialien/-dienstleistungen, (ii) Probanden-/Strahlenhaftpflichtversicherung und (iii) Studienverträge werden Checkboxen vorgelegt. Diese können Experten in der Klinikadministration sowie Studienleiter und PIs zur operationalen Vorbereitung/Initiierung künftig weiterer (Bildgebungs-)Studien nutzen.
Schlussfolgerung Durch EDV-gestützte Verwaltungsworkflows und in der Studienkoordination versierte Mitarbeiter können der Rekrutierungsstart und nachfolgende Patienteneinschlüsse bei klinischen Studien beschleunigt und damit Kosten gesenkt werden. Für Bildgebungsstudien ist dies besonders wichtig, da diese wegen der Anwendung radioaktiver Stoffe bzw. Strahlung am Menschen besonders komplex und daher bei Verwaltungsvorgängen teils viele weitere Fachabteilungen in der Organisation wie Strahlenschutz, Medizinphysik/-technik oder Qualitätsmanagement zu involvieren sind.
Structural Insights into the TES/TFA Reduction of Differently Substituted Benzofurans: Dihydrobenzofurans or Bibenzyls?
Authors: Chiummiento Lucia , D’Orsi Rosarita , Caivano Ilaria , Funicello Maria , Lupattelli Paolo 
Published: October 2020

AbstractVarious polysubstituted benzofurans were reduced by using triethylsilane in trifluoracetic acid. 2,3-Dihydrobenzofurans or bibenzyl compounds were obtained in high yields, depending on the nature of the substituents at C2 and on the benzene ring of the core structure. A p-anisole substituent at C2 of benzofurans always led to the corresponding bibenzyls.
Change is not the only constant
Authors: Wright Patricia 
Published: October 2020

Abstract
Developments in information technology during the past 40 years have presented new opportunities for information designers and also posed new challenges. Computer controlled displays are now so ubiquitous that most people in everyday life need to interact with information shown on screens. Many of the characteristics of these readers have not changed: they forget things, get distracted, make assumptions, etc. Research has confirmed that designing an interaction style to reduce the demands made on people’s sensory and cognitive processes helps them accomplish tasks more easily. There has undoubtedly been progress, particularly with mobile devices. Graphical user interfaces and touch screens can make interactions feel intuitive, almost conversational, but interface glitches remain. These arise both from the tension inherent in designing for experienced and novice users, and from design decisions often involving people with differing priorities. The features of interfaces will continue to change but the challenge of finding ways to support people’s sensory, cognitive and conative characteristics will continue.
The legitimization of the use of sweat shops by H&M in the Swedish press
Authors: Cotal San Martin Vladimir , Machin David 
Published: October 2020

Abstract
In the Swedish news-media we find sporadic critical, or reflective, reporting on the production conditions of Swedish
‘sweat-shop’ factories in the Global South, used to supply Transnational Corporations (TNCs). In this paper we carry out a critical
discourse analysis, in particular using Van Leeuwen’s social actor and social action analysis, to look at examples from a larger corpus of
88 news reports and editorials from the Swedish press, between 2012–2017, which report and comment on activities of the Swedish company
H&M in relation to its production chains. Analysis reveals how these recontextualize events, processes and motives, to represent Sweden
and Swedish TNCs as characterized by a benevolent, democratic, humane, form of capitalism, drawing on discourses of a former social
democratic Sweden of the 1960s before it became highly neo-liberalized. This nationalism converges with other discourses promoting the
exploitation of the Global South.
Positively bitter and negatively sweet?
Authors: Yoon Suwon 
Published: October 2020

AbstractThe goal of this study is to propose a pragmatic analysis of what we callEmotive Taste Terms(ETTs) in Korean, compared to English. What makes Korean taste adjectives special is its multidimensional meaning: In descriptive dimension, (i) the literal meaning concerns the taste; or (ii) it can be extended toward the situation, yielding a figurative meaning. In expressive dimension, (iii) the choice of particular derivation form reflects the speaker’s positive or negative emotional attitude; and (iv) another potential expressive meaning concerns honorification, thought it is not part of the meaning of ETTs. We thus propose that ETTs are a novel subcase ofexpressiveelements, triggeringConventional Implicature. We show how the analysis of ETTs as a CI allows us to successfully derive subtle connotational differences amongst numerous variants. Finally, we show how the co-occurrence pattern of multiple expressives, ETTs and other expressives, within the sentence can be captured byCompatibility Condition Model.
Taboo vocatives in the language of London teenagers
Authors: Palacios Martínez Ignacio M. 
Published: October 2020

AbstractThis study focusses on the use and functions of so-called taboo vocatives (e.g.dickhead, you bastard, bitch) in the language of London teenagers, based on the analysis of over 500 examples extracted from COLT (The Bergen Corpus of London Teenage Language) and LEC (London English Corpus). Findings illustrate a wide variety of items in this category, and show that these cannot be regarded as mere insults, since they often serve to reinforce the bonds between young speakers as well, and indeed can even carry affectionate connotations. The majority of these items are nouns and denote some kind of sexual reference, an abnormal or strange human condition, or a pejorative, animal-related allusion. There does not seem to have been any major changes in the use of these forms from the 1990s to the first decades of the current century, although many of them have broadened their meaning and can now be used with either male or female speakers.
Everything is inside the home: the boundaries of home confinement during the Italian lockdown
Authors: Risi Elisabetta , Pronzato Riccardo , Di Fraia Guido 
Published: October 2020

ABSTRACT
This article investigates the ways in which social distancing and home confinement restrictions have been experienced and perceived in the Italian socio-cultural context, in order to assess how they reshaped everyday life, and which are their social implications. Drawing on 60 in-depth semi-structured interviews, this article sheds light on the sense-making processes and the construction of inter-subjective meaning around home confinement and social distancing that emerged during the lockdown. Results support that during the national quarantine individuals had to reframe everyday practices, thereby redefining the boundaries of their experience. Indeed, individuals had to deal with a lack of personal spaces, a following stress overload and a collapse of the typical boundaries between the professional and private sphere, which required a complex management of everyday activities. Implications of these preliminary findings are discussed, as well as suggestions for future research.
A class of conserved currents for linearized gravity in the Kerr spacetime
Authors: Grant Alexander M , Flanagan Éanna É 
Published: October 2020

Abstract
We construct a class of conserved currents for linearized gravity on a Kerr background. Our procedure, motivated by the current for scalar fields discovered by Carter (1977), is given by taking the symplectic product of solutions to the linearized Einstein equations that are defined by symmetry operators. We consider symmetry operators that are associated with separation of variables in the Teukolsky equation, as well as those arising due the self-adjoint nature of the Einstein equations. In the geometric optics limit, the charges associated with these currents reduce to sums over gravitons of positive powers of their Carter constants, much like the conserved current for scalar fields. We furthermore compute the fluxes of these conserved currents through null infinity and the horizon and identify which are finite.
Spin waves in skyrmionic structures with various topological charges
Authors: Rózsa Levente , Weißenhofer Markus , Nowak Ulrich 
Published: October 2020

Abstract
Equilibrium properties and localized magnon excitations are investigated in topologically distinct skyrmionic textures. The observed shape of the structures and their orientation on the lattice is explained based on their vorticities and the symmetry of the crystal. The transformation between different textures and their annihilation as a function of magnetic field is understood based on the energy differences between them. The angular momentum spin-wave eigenmodes characteristic of cylindrically symmetric structures are combined in the distorted spin configurations, leading to avoided crossings in the magnon spectrum. The susceptibility of the skyrmionic textures to homogeneous external fields is calculated, revealing that a high number of modes become detectable due to the hybridization between the angular momentum eigenmodes. These findings should contribute to the observation of spin waves in distorted skyrmionic structures via experiments and numerical simulations, widening the range of their possible applications in magnonic devices.
Improved band gaps and structural properties from Wannier–Fermi–Löwdin self-interaction corrections for periodic systems
Authors: Shinde Ravindra , Yamijala Sharma S R K C , Wong Bryan M 
Published: October 2020

Abstract
The accurate prediction of band gaps and structural properties in periodic systems continues to be one of the central goals of electronic structure theory. However, band gaps obtained from popular exchange–correlation (XC) functionals (such as LDA and PBE) are severely underestimated partly due to the spurious self-interaction error (SIE) inherent to these functionals. In this work, we present a new formulation and implementation of Wannier function-derived Fermi–Löwdin (WFL) orbitals for correcting the SIE in periodic systems. Since our approach utilizes a variational minimization of the self-interaction energy with respect to the Wannier charge centers (WCC), it is computationally more efficient than the HSE hybrid functional and other self-interaction corrections that require a large number of transformation matrix elements. Calculations on several (17 in total) prototypical molecular solids, semiconductors, and wide-bandgap materials show that our WFL self-interaction correction approach gives better band gaps and bulk moduli compared to semilocal functionals, largely due to the partial removal of self-interaction errors.
Surface crack characterization using laser nonlinear ultrasonics based on the bispectrum
Authors: Liu Hui , Wang Zhaoba , Zheng Bin 
Published: October 2020

Abstract
Laser nonlinear wave modulation spectroscopy (LNWMS) has been used to detect nonlinear ultrasonic signatures caused by fatigue cracks in materials. The nonlinear feature extraction from the spectral plot plays a significant role in LNWMS. This paper uses the bispectrum to distinguish harmonically related signals which result from nonlinear interactions and to remove those which do not. A feature called bispectrum damage factor (BDF), which is defined as the ratio of the bispectrum peak difference value of the damage and intact signals to the bispectrum peak value of intact signals at frequencies F
1, F
2, is extracted from the bispectral plot to characterize the crack features. The basic premise of the proposed laser nonlinear wave modulation bispectrum (LNWMBS) is that this BDF value will vary regularly as the level of crack-induced nonlinearity increases. A finite element model and a noncontact laser ultrasonic system have been built for LNWMBS measurement. The simulation results show that the BDF value is sensitive to crack depth and angle, and is insensitive to crack length and detecting position. BDF values of reflected Rayleigh waves are positive and approximately linearly increase with an increase of the crack depths in the range of 0.1 λ ∼ 0.6 λ (λ is the corresponding wavelength of adopted frequency); meanwhile, the values of the transmitted waves are negative and decreasing. The BDF values are larger than the crack angle at 90° when they are less than 90°, which is beneficial for crack detection. The proposed LNWMBS technique has been successfully tested for detecting artificial sub-millimeter surface-breaking cracks in aluminum alloy plates and closed fatigue cracks of torque load simulator connection blocks.
Numerical computations of geometric ergodicity for stochastic dynamics
Authors: Li Yao , Wang Shirou 
Published: October 2020

Abstract
A probabilistic approach to compute the geometric convergence rate of a stochastic process is introduced in this paper. The goal is to quantitatively compute both the upper and lower bounds for rate of the exponential convergence to the stationary distribution of a stochastic dynamical system. By applying the coupling method, we derive an algorithm which does not rely on the discretization of the infinitesimal generator. In this way, our approach works well for many high-dimensional examples. We apply this algorithm to the random perturbations of both iterative maps and differential equations. We show that the rate of geometric ergodicity of a random perturbed system can, to some extent, reveal the degree of chaoticity of the underlying deterministic dynamics. Various SDE models including the ones with degenerate noise or living on the high-dimensional state space are also explored.
Determination of plasma parameters by spectral line broadening in an electrosurgical argon plasma
Authors: Hillebrand Bastian , Iglesias Enrique , Gibson Andrew R , Bibinov Nikita , Neugebauer Alexander , Enderle Markus , Awakowicz Peter 
Published: October 2020

Abstract
An electrosurgical argon plasma with a 5% admixture of molecular hydrogen is studied in order to investigate time averaged plasma parameters by optical emission spectroscopy (OES). Electron densities in the range of 1015–1016 cm−3 are determined from the Stark broadening of the time averaged line profiles of the Balmer-α and -β emission lines of hydrogen. A two-profile fit corresponding to regions of different electron densities is found to provide a better representation of the line broadening than a single profile fit. This is consistent with time resolved ICCD imaging, acquired with 150 ns time resolution, that shows strong radial gradients in the plasma emission and the asymmetry produced by the discharge arrangement. Gas temperatures are determined using two different methods. Firstly, simulated spectra for different rotational temperatures are fitted to the measured N2(C-B, 0-1) emission band originating from ambient air diffusion into the argon/hydrogen gas flow. From the best fit, rotational temperatures between 1500 K and 1800 K are inferred. These measurements are in good agreement with those inferred by the second method, which is based on the collisional broadening of the emission lines of neutral argon at 750 nm and 751 nm. This latter method may be useful for the measurement of gas temperatures when the device is used inside hollow organs during endoscopic or laparoscopic interventions, where air mixing will be limited. Therefore, the results of this study are highly relevant to applications of these devices, e.g. for controlling tissue effects and the avoidance of excessive heating.

Abstract
The γ-decays of 12C excited levels (the Hoyle state 0+ at 7.65 MeV and the 9.64 MeV 3) are essential for its production in the universe. We present here a new attempt to precisely measure such γ-decay probabilities. The measurement was performed at INFN-LNS in Catania using the 4π CHIMERA multidetector. In order to measure these low probability decay-channels we performed 4-fold coincidence measurements. The 12C target nuclei were excited by using a beam of 64 MeV α-particles produced by the Superconducting Cyclotron (CS) of INFN-LNS. The scattered α-particles and the 12C recoils were detected and identified by? E-E and ToF methods using CHIMERA telescopes. The two emitted γ-rays in the decay chain were detected and identified by using the second stage of the telescopes, CsI(Tl) scintillators, by means of fast-slow and rise time techniques. Kinematics and energy-momentum conservation laws were used to constrain the data analysis. Also the 3-α decay channel probability was measured. Such a simultaneous measurement of all known decay channels was useful to reduce the systematic errors. Preliminary results of the data analysis are reported.
Nucleosynthesis in early rotating massive stars and chemical composition of CEMP stars
Authors: Choplin A , Hirschi R 
Published: October 2020

Abstract
The first massive stars triggered the onset of chemical evolution by releasing the first metals (elements heavier than helium) in the Universe. The nature of these stars and how the early chemical enrichment took place is still largely unknown. Rotational-induced mixing in the stellar interior can impact the nucleosynthesis during the stellar life of massive stars and lead to stellar ejecta having various chemical compositions. We present low and zero-metallicity 20, 25 and 40 M⊙ stellar models with various initial rotation rates and assumptions for the nuclear reactions rates. With increasing initial rotation, the yields of light (from ∼ C to Al) and trans-iron elements are boosted. The trans-iron elements (especially elements heavier than Ba) are significantly affected by the nuclear reaction uncertainties. The chemical composition of the observed CEMP (carbon-enhanced metal-poor) stars CS29528-028 and HE0336+0113 are consistent with the chemical composition of the material ejected by a fast rotating 40 M⊙ model.

Published: October 2020

Abstract
Resonant Schottky cavity pickups have applications in the measurements of beam parameters in a storage ring. Apart from that they can be used in nondestructive in-ring decay studies of radioactive ion beams. In order to obtain the results of an experiment suitable Data Acquisition System (DAQ) is necessary. Several DAQs were used at Experimental Storage Ring (ESR) at GSI based on the different hardware and software solutions such as TCAP or NTCAP. The goal of this work is to design a prototype of a DAQ using open hardware and open source software defined radio (SDR) and conduct the test measurements at ESR.

Abstract
Heavy nuclei are mainly synthesised by a sequence of neutron captures and β-decays. The corresponding neutron energies in the different astrophysical sites range from 1keV to 1MeV. By using the activation technique, small neutron capture cross sections can be studied. A sample is irradiated by a quasi-stellar neutron spectrum in order to produce radioactive isotopes. The decay of the radioactive nuclei can be detected by their characteristic gamma rays. For this purpose, sensitive experimental detector equipment is needed.
Two Broad Energy Germanium Detectors (BEGe) were recently built up at the Goethe University Frankfurt. The first measurement of the partial neutron capture cross sections for the reaction 181Ta(n,γ) has been performed by using the activation technique.

Abstract
A new detector setup (NICE-detector) based on an organic plastic scintillator is presented. It will be used during experiments measuring neutron-induced reactions with a charged particle in the exit channel. The proposed design was tested at the Goethe University Frankfurt. One of the test cases was the capture cross-section of 209Bi at different astrophysically important energies, including thermal capture cross-section and resonance integral. This research presents the performance of the detector setup, as well as preliminary results for the calculated cross-sections. The preliminary results demonstrate that the newly developed NICE-detector can be used to determine capture cross-sections with sufficient accuracy, and might be adopted in the future as an alternative for charged particle measurements in different nuclear and astrophysical applications.
