title: Berufsorientierende Elemente im literarischen Lernkontext
Creators: name: Orucevic, Elma
Year: 2021

description: Im Spannungsfeld von Rezeptionsästhetik, Literaturanalyse und Bildungsauftrag wird anhand der ausgewählten Romanreihe zur Figur Anastasia Krupnik, von Lois Lowry aus der Gattung Kinder- und Jugendliteratur der Leitfrage nachgegangen, ob literarische Lernprozesse mit berufsorientierendem Lernen einhergehen können. Kann durch entsprechende Lektüreauswahl berufsorientierender Literaturunterricht oder ein literaturbezogener Berufsorientierungsunterricht einen Beitrag zur späteren Berufswahlentscheidung von Schülerinnen und Schülern leisten? Dafür werden sechs Kategorien von berufsorientierenden Elementen im Text vorausbestimmt, um sie textimmanent hinsichtlich einer möglichen Wirkung auf die Leser und ihrer Funktion im Text zu analysieren. Das Ergebnis ist der Ansatz einer Definition zu berufsorientierenden Elementen in literarischen Lernkontexten.
description: In the area of tension between the aesthetics of reception, literature analysis, and the educational mission, the selected series of novels about the character Anastasia Krupnik, created by Lois Lowry from the genre of children's and young adult literature, will be used to pursue the key question of whether literary learning processes can go hand in hand with career-oriented learning. Can career-oriented literature lessons or literature-related career-oriented instruction contribute to the later career choice of schoolchildren through the appropriate choice of reading material? For this purpose, six categories of career-oriented elements in the text are pre-determined with the goal to analyze them text-immanently with regard to a possible effect on the readers and their function in the text. The result is a definition of career-oriented elements in literary learning contexts.

title: Räumlicher Verlauf der Polarisation in Domänenwänden von PbTiO3
Creators: name: Weselka, Clemens
Year: 2021

description: Das Material PbTiO3 zeigt bei Temperaturen unter TC = 765K (492°C) ferroische Eigenschaften (spontane Polarisation und elastische Verzerrung auf atomarer Ebene) in den Einheitszellen seines Kristallgitters. Bei der Unterschreitung dieser kritischen Temperatur TC findet ein struktureller Phasenübergang in diesem statt, welcher zu einer Struktur aus Domänen (z.B. Bereichen mit entgegengesetzter spontaner Polarisation) getrennt durch Domänenwände im mikroskopischen Aufbau führt (2). Diese Domänen entsprechen Bereichen im Kristallgitter mit verschiedener Orientierung. Eine Berechnung der räumlichen Verteilung ferroischer Eigenschaften wie der Polarisation an Grenzflächen zwischen Domänen (d.h. in Domänenwänden) in einem durch Anwendung der Dichtefunktionaltheorie simulierten PbTiO3 Kristallvolumen, existiert bereits in einer Publikation. Die Gruppentheorie liefert Anzahl und Arten von möglichen Domänenzuständen bei dem entsprechenden ferroischen Phasenübergang, da dieser mit einer Verringerung der Kristallsymmetrie einhergeht. Damit lassen sich Domänenpaare erstellen, welche durch eine Domänenwand getrennt sind und eine entgegengesetzte Polarisation aufweisen. Die Domänenwand erstreckt sich dabei über einige Atomlagen (bzw. hat die Dicke einiger Einheitszellen des Kristalls). In dieser Masterarbeit werden, aufbauend auf den oben zusammengefassten Erkenntnissen über die ferroischen Eigenschaften des Phasenübergangs von PbTiO3, die irreduziblen Darstellungen (in Matrixform) des Phasenübergangs bei T < TC aufgestellt. Die möglichen Symmetrieoperationen (Invarianten) dieses Symmetrieabstieges auf die Tieftemperaturphase erlauben eine (räumliche) Einschränkung der Ordnungsparameter (wie z.B. der spontanen Polarisation) in den entstehenden Domänenstrukturen und liefern eine Möglichkeit über Symmetrierelationen den räumlichen Verlauf des Ordnungsparameters in unterschiedlichen Kombinationen auftretende Domänenzwillinge im Material zu berechnen. Durch eine auf der Landau-Theorie basierenden Berechnung der Invarianten der freien Energie (diese bestimmen auch die Eigenschaften der Domänenwände und den möglichen Verlauf der Polarisation in diesen), wird eine theoretische Darstellung der Domänenwände für 180°-Domänenzwillinge ausgearbeitet und die Ergebnisse, wie mögliche räumliche Verläufe der Polarisation in den Wandstrukturen und die materialspezifischen Werte der freien Energie in den DW, mit bereits existierenden Literaturergebnissen verglichen.

description: Quasisymmetric stellarators are a type of optimized stellarators for which flows are undamped to lowest order in an expansion in the normalized Larmor radius. However, perfect quasisymmetry is impossible. Since large flows may be desirable as a means to reduce turbulent transport, it is important to know when a stellarator can be considered to be sufficiently close to quasisymmetry. The answer to this question depends strongly on the size of the spatial gradients of the deviation from quasisymmetry and on the collisionality regime. Recently, formal criteria for closeness to quasisymmetry have been derived in a variety of situations. In particular, the case of deviations with large gradients was solved in the $1/ν$ regime. Denoting by $α$ a parameter that gives the size of the deviation from quasisymmetry, it was proven that particle fluxes do not scale with $α^{3/2}$, as typically claimed, but with $α$. It was also shown that ripple wells are not necessarily the main cause of transport. This paper reviews those works and presents a new result in another collisionality regime, in which particles trapped in ripple wells are collisional and the rest are collisionless.

description: We have conducted a search for open clusters in the vicinity of classical Galactic Cepheids based on high-quality astrometry from the third data release (DR3) of the ESA mission Gaia to improve the calibration of the Leavitt law (LL). Our approach requires no prior knowledge of existing clusters, allowing us to both detect new host clusters and cross-check previously reported associations. Our Gold sample consists of 34 Cepheids residing in 28 open clusters, including 27 fundamental mode and 7 overtone Cepheids. Three new bona fide cluster Cepheids are reported (V0378 Cen, ST Tau, and GH Lup) and the host cluster identifications for three others (VW Cru, IQ Nor, and SX Vel) are corrected. The fraction of Cepheids occurring in open clusters within 2 kpc of the Sun is $f_{CC,2kpc} = 0.088^{+0.029}_{-0.019}$. By combining cluster and field Cepheids, we calibrate the LL for several individual photometric passbands, together with reddening-free Wesenheit magnitudes based on Gaia and HST photometry, while solving for the residual offset applicable to Cepheid parallaxes, $Δ\varpi_{\mathrm{Cep}}$. The most direct comparison of our results with the SH0ES distance ladder yields excellent ($0.3σ$) agreement for both the absolute magnitude of a 10d solar metallicity Cepheid in the near-IR HST Wesenheit magnitudes, $M_{H,1}^W=-5.914\pm 0.017$ mag, and the residual parallax offset, $Δ\varpi_{\mathrm{Cep}}=-13 \pm 5\,μ$as. Using the larger sample of 26 Gold cluster Cepheids and $225$ MW Cepheids with recent Gaia DR3 astrometry and photometry, we determine at solar metallicity $M_{G,1}^W = -6.004 \pm 0.019$\,mag and $Δ\varpi_{\mathrm{Cep}}=-19 \pm 3\,μ$as. These results mark the currently most accurate absolute calibrations of the Cepheid luminosity scale based purely on observations of MW Cepheids.

description: Immer mehr Branchen und Regionen sind vom Fachkräftemangel betroffen. Doch es gibt eine vielversprechende Lösung: Teilqualifikationen (TQs). Die Auswertung von 4,3 Millionen Online-Jobanzeigen für Hilfskräfte und Fachkräfte aus dem Jahr 2022 durch den Jobmonitor der Bertelsmann Stiftung zeigt: oft reichen schon zwei bis vier von maximal sieben Teilqualifikationen eines Berufs aus, um den Großteil der freien Stellen zu besetzen. Diese Teile können in mehrwöchigen Teilqualifizierungen erlernt werden. Welche TQs besonders häufig nachgefragt werden unterscheidet sich dabei von Region zu Region. Der Jobmonitor macht diese Unterschiede transparent und gibt wichtige Hinweise auf lokale Weiterbildungsbedarfe, die die lokale Qualifizierungspolitik im Blick haben sollte. Die Studie zeigt damit das große Potenzial von Teilqualifikationen, um dafür zu sorgen, dass vor Ort der jeweilige regionale Fachkräftebedarf schneller gedeckt werden kann.
Probing system size dependence at high baryon density by systematic comparison of Ag+Ag and Au+Au reactions at 1.23$A$ GeV

description: We present UrQMD predictions for the comparison of the recently measured Ag+Ag and Au+Au runs at a beam energy of $E_\mathrm{lab}$ = 1.23~$A$GeV explored by the HADES experiment. To this aim, different centrality definitions are investigated: We suggest that in the case of particle production, both systems should be compared at the same number of participating nucleons, while for a comparison of the (elliptic) flow, a selection on the initial state eccentricity - as in high energy reaction - is better suited. Generally, we find good agreement between both system, if these centrality criteria are used. Specifically, the deuteron yields per participant and the pion to proton ratios are shown to scale with $A_\mathrm{part}$ except for very central Ag+Ag reactions due to stronger stopping in such reactions. The elliptic flow in both systems follows inital state eccentricity scaling, albeit with the opposite sign as compared to high energies, suggesting a strong relation between final flows and the initial state also at the low energies explored here. The observation of this scaling might then allow to obtain further information on the expansion properties (and the EoS) of matter at high baryon densities.

description: We study AC electric($σ$), thermoelectric($α$), and thermal($\barκ$) conductivities in a holographic model, which is based on 3+1 dimensional Einstein-Maxwell-scalar action. There is momentum relaxation due to massless scalar fields linear to spatial coordinate. The model has three field theory parameters: temperature($T$), chemical potential($μ$), and effective impurity($β$). At low frequencies, if $β< μ$, all three AC conductivities($σ, α, \barκ$) exhibit a Drude peak modified by pair creation contribution(coherent metal). The parameters of this modified Drude peak are obtained analytically. In particular, if $β\ll μ$ the relaxation time of electric conductivity approaches to $2\sqrt{3} μ/β^2$ and the modified Drude peak becomes a standard Drude peak. If $β> μ$ the shape of peak deviates from the Drude form(incoherent metal). At intermediate frequencies($T

description: Multi-view representation learning is essential for many multi-view tasks, such as clustering and classification. However, there are two challenging problems plaguing the community: i)how to learn robust multi-view representation from mass unlabeled data and ii) how to balance the view consistency and the view specificity. To this end, in this paper, we proposed a hybrid contrastive fusion algorithm to extract robust view-common representation from unlabeled data. Specifically, we found that introducing an additional representation space and aligning representations on this space enables the model to learn robust view-common representations. At the same time, we designed an asymmetric contrastive strategy to ensure that the model does not obtain trivial solutions. Experimental results demonstrated that the proposed method outperforms 12 competitive multi-view methods on four real-world datasets in terms of clustering and classification.

description: We use the virial expansion to investigate the behavior of the two-component, attractive Fermi gas in the high-temperature limit, where the system smoothly evolves from weakly attractive fermions to weakly repulsive bosonic dimers as the short-range attraction is increased. We present a new formalism for computing the virial coefficients that employs a diagrammatic approach to the grand potential and allows one to easily include an effective range $R^*$ in the interaction. In the limit where the thermal wavelength $λ\ll R^*$, the calculation of the virial coefficients is perturbative even at unitarity and the system resembles a weakly interacting Bose-Fermi mixture for all scattering lengths $a$. By interpolating from the perturbative limits $λ/|a| \gg 1$ and $R^*/λ\gg 1$, we estimate the value of the fourth virial coefficient at unitarity for $R^*=0$ and we find that it is close to the value obtained in recent experiments. We also derive the equations of state for the pressure, density and entropy, as well as the spectral function at high temperatures.

Publisher: name: F1000 Research Limited

description: Background:

UCL Medical School is dedicated to delivering world class education and producing doctors ready to thrive in modern healthcare. Understanding and responding to the evolving needs of the population it serves is fundamental to this.



A module was developed for first year medical students to help them navigate the complexities of clinical reasoning and the more political and ethical aspects of healthcare



Summary of Work

An eight-week module was delivered weekly to the entire cohort of first year medical students. The first five lecture-based sessions centred around clinical cases, integrating important issues such as race equality, LGBTQI issues, social inequality, microaggressions, wellbeing, and professionalism. The remaining sessions focussed on developing essential presentation, feedback, and reflective writing skills, with the final two sessions run in small groups.



Sessions were co-designed with students, patients, and subject experts. Students considered how to ensure equitable access to healthcare for all, whilst exploring the impact of healthcare’s colonial past, and looking at the initiatives and progress the healthcare community has already made, future challenges for the NHS and potential solutions. 



Summary of Results

Toolkit Sessions:

 Sexual and Reproductive Health  
 Mental Health
 Everyday-isms and Microaggressions
 Emergency Care and Dilemmas
 Healthcare Racism
 Innovation, sustainability, presentation skills, constructive feedback and reflective writing skills
 Microteach (half the cohort))
 Microteach (half the cohort)

Students submitted a mandatory reflective essay three weeks after the final session.



Discussion and Conclusion



The sessions were well received by students but several challenges were encountered during design and delivery:

 Small group discussions may have been a better format for all content delivery.
 Delays in room booking confirmation meant short notice about whether sessions would be remote or in person.
 Remote access to lectures resulted in declining attendance as the weeks progressed.
 Recruiting facilitators for the microteaches and assignment markers might have been easier with funding.

This toolkit delivered challenging topics and case studies to new medical students in an interactive and engaging format. Formal feedback is currently underway. Discussions with students and their questions indicated they had understood key points and were reflecting on what they had learnt.



Take home message

Designing a module where politics, ethics and social responsibility are effectively integrated with clinical cases requires significant planning, involvement from multiple stakeholders, and careful evaluation to ensure students maximally benefit from the content of the sessions.

description: Controlling the decoherence induced by the interaction of quantum system with its environment is a fundamental challenge in quantum technology. Utilizing Floquet theory, we explore the constructive role of temporal periodic driving in suppressing decoherence of a spin-1/2 particle coupled to a spin bath. It is revealed that, accompanying the formation of a Floquet bound state in the quasienergy spectrum of the whole system including the system and its environment, the dissipation of the spin system can be inhibited and the system tends to coherently synchronize with the driving. It can be seen as an analog to the decoherence suppression induced by the structured environment in spatially periodic photonic crystal setting. Comparing with other decoherence control schemes, our protocol is robust against the fluctuation of control parameters and easy to realize in practice. It suggests a promising perspective of periodic driving in decoherence control.

description: Die vorliegende Masterarbeit versteht sich als Studie des Phänomens der Politisierung der Literatur im Dritten Reich. Das Ziel der Arbeit ist es, die möglichst ausführliche Schilderung der NS-Romane zu liefern, die zum Instrument der nationalsozialistischen Propaganda wurden. Die Primärliteratur bilden ein Frauenroman und ein historischer Roman, die zwischen 1933 und 1937 in Deutschland veröffentlicht wurden und Bestsellerstatus erreicht haben. Die Zielsetzung der vorliegenden Arbeit lässt sich in Form von vier Teilzeilen formulieren. Das erste Kapitel thematisiert die politischen, ideologischen und sozialhistorischen Wurzeln des Nationalsozialismus und dient gleichzeitig als geschichtliche Einführung zum Thema der Arbeit. Das zweite Kapitel beschäftigt sich mit der Literaturpolitik und dem Aufbau des Literaturbetriebes im Dritten Reich. Das dritte Kapitel liefert einen Einblick in das Thema der literarischen Produktion im Dritten Reich mit Rücksicht auf den Begriff „NS-Literatur“, die nationalsozialistische Ästhetik und die Stellungnahme zum NS-Regime von den wichtigsten deutschsprachigen Literaten. Zum Schwerpunkt des vierten Kapitels wurde das eigentliche Thema der Arbeit – „Literatur im Dienst der Propaganda: Propagandaromane im Dritten Reich“. Das Kapitel enthält eine Interpretation der zwei ausgewählten nationalsozialistische Bestseller-Romane. In diesem Teil werden unter anderen die Rolle und die Funktion der Frau in der NS-Literatur sowie der literarische Antisemitismus und Führerkult geschildert, die in den ausgewählten Romanen geschildert wurden. Die Darstellung der Literatur als Propagandainstrument des NS-Regimes wurde zum Fokus der Analyse.

description: A colorless c-cbar dipole emerging from a heavy ion collision and developing the charmonium wave function can be broken-up by final state interactions (FSI) propagating through the hot medium created in the collision. We single out two mechanisms of charmonium attenuation: (i) Debye color screening, called melting; and (ii) color-exchange interaction with the medium, called absorption. The former problem has been treated so far only for charmonia at rest embedded in the medium, while in practice their transverse momenta at the LHC are quite high, =7-10 GeV^2. We demonstrate that a c-cbar dipole may have a large survival probability even at infinitely high temperature. We develop a procedure of Lorentz boosting of the Schroedinger equation to a moving reference frame and perform the first realistic calculations of the charmonium survival probability employing the path-integral technique, incorporating both melting and absorption. These effects are found to have comparable magnitudes. We also calculated the FSI suppression factor for the radial excitation psi(2S) and found it to be stronger than for J/psi, except large p_T, where psi(2S) is relatively enhanced. The azimuthal asymmetry parameter v_2 is also calculated.

description: Starting from exact analytical results on singular values and complex eigenvalues of products of independent Gaussian complex random $N\times N$ matrices also called Ginibre ensemble we rederive the Lyapunov exponents for an infinite product. We show that for a large number $t$ of product matrices the distribution of each Lyapunov exponent is normal and compute its $t$-dependent variance as well as corrections in a $1/t$ expansion. Originally Lyapunov exponents are defined for singular values of the product matrix that represents a linear time evolution. Surprisingly a similar construction for the moduli of the complex eigenvalues yields the very same exponents and normal distributions to leading order. We discuss a general mechanism for $2\times 2$ matrices why the singular values and the radii of complex eigenvalues collapse onto the same value in the large-$t$ limit. Thereby we rederive Newman's triangular law which has a simple interpretation as the radial density of complex eigenvalues in the circular law and study the commutativity of the two limits $t\to\infty$ and $N\to\infty$ on the global and the local scale. As a mathematical byproduct we show that a particular asymptotic expansion of a Meijer G-function with large index leads to a Gaussian.

description: Supersymmetric models with R-parity violation (RPV) have become more popular following the lack of any excess of missing energy events at the 8 TeV LHC. To identify such models, the suggested searches generally rely on the decay products of the (effectively) lightest supersymmetric particle (LSP), with signals that depend on the identity of the LSP and the relevant RPV operators. Here we look at the prospects for detecting RPV chargino decays at the LHC and find substantial patches of parameter space in the Minimal Supersymmetric Standard Model with possibly spectacular signatures, such as three charged-lepton resonances.

description: In this manuscript, we study the nearly flat approximation of a conformally invariant gravitational theory in metric measure space (MMS). In addition, we investigate the transformation of the energy-momentum tensor in this context and obtain the vacuum solution of MMS and its weak field limit in the spherically symmetric coordinates. We show that while it is already a vacuum solution, it can simulate dark matter when restricted to the framework of general relativity, i.e., a symmetry-broken conformal frame. This is done by employing a density function which is an essential part of MMS. We derive an equation for the density function for a general profile of a rotation curve obtained from observations. Specifically, the density function corresponding to two well-known profiles PSS and NFW are provided.

title: Drei Hochzeiten und ein Todesfall
Creators: name: Rubner, Jasmin
Year: 2021

description: Der Aufstieg der Ottonen kann auch anhand ihrer Eheprojekte verfolgt werden. Vor allem herrschaftliche Erhöhungen wurden durch Hochzeiten markiert: Auf diesen Umstand wurde von der Forschung bisher zwar verwiesen, aber eine vergleichende, auf diese Perspektive fokussierte Betrachtung ist bislang ausgeblieben. Die vorliegende Arbeit untersucht die frühottonische Heiratspolitik des 10. Jahrhunderts und führt dabei aus, dass Ehen, wie auch Ehefeiern und -verhandlungen ein Mittel außenpolitischer Vernetzung waren. Sie betrafen aber auch innerdynastische Fragen wie etwa Nachfolgeregelungen. Die Eheschließungen Edgiths, Adelheids und Theophanus in das ottonische Haus werden unter Berücksichtigung ihrer Intentionen, Ausführungen und Folgen miteinander verglichen. Als Quellen für diese Untersuchung dienen in erster Hinsicht die historiographischen Berichte Widukinds von Korvei, Hrotsvits von Gandersheim, Liudprands von Cremona und Thietmars von Merseburg, die als Chronisten auf die Geschichte des ottonischen Königs- und später Kaiserhauses ausgerichtet waren. Ihre Berichte werden auf Gemeinsamkeiten, Widersprüche und Wertungen der Vermählung hin untersucht. Im Verlauf der Arbeit werden die Wichtigkeit verwandtschaftlicher Verbindungen, der herrschaftliche Rang der Ehepartner, die diplomatischen Beziehungen der beteiligten Dynastien sowie die von den Darstelllungen der Eheschließungen ausgehende narrative Wirkmacht expliziert.
description: The Ottonian family’s ascent to prominence can, amongst other factors, be traced back to their marriage projects. Weddings were especially used to denote the achievement of a higher rank: So far, several researchers have pointed this fact out, but a comparison focused on the marital aspect has failed to materialise. The paper at hand investigates the early Ottonians’ marriage policy and shows that marriages, as well as marriage negotiations and celebrations, were a means of networking in foreign policy. But marriages also concerned dynastic interests, such as succession plans. The marriages of Edgith, Adelheid, and Theophanu to the Ottonian dynasty are compared with each other, keeping the planners’ intentions, as well as the marriage’s executions and consequences in mind. The historiographical accounts of Widukind of Corvey, Hrotsvitha of Gandersheim, Liudprand of Cremona, and Thietmar of Merseburg are the primary sources used in this investigation, who were focused on the Ottonian dynasty’s royal, and later even imperial history in their function as chroniclers. The accounts of each wedding are compared regarding similarities, contradictions, and biases of their respective authors. In due course, this paper explains the importance of familial relations, the spouse’s noble rank, the diplomatic relations between the dynasties involved and the narrative power exerted by portrayals of marriage.

description: Emotions and affects are an omnipresent aspect of all interaction, but they are rarely explicated in words. In conversation analysis the terms ‘emotion’ and ‘affect’ are used often interchangeably to refer to observable aspects of sentiments emerging in and through interaction (Ruusuvuori 2013: 332).

description: The millisecond pulsar MAXI J1816-195 was recently discovered in an outburst by MAXI in 2022 May. We study different properties of the pulsar using data from NuSTAR and NICER observations. The unstable burning of accreted material on the surface of neutron stars induces thermonuclear (Type-I) bursts. Several such thermonuclear bursts have been detected by MAXI J1816-195 during its outburst. We investigate the evolution of the burst profile with flux and energy using NuSTAR and NICER observations. During the NuSTAR observation, a total of four bursts were detected from the source. The duration of each burst is around $\sim$ 30 s and the ratio of peak to persistent count rate is $\sim$ 26 as seen from the NuSTAR data. The burst profiles are modelled using a sharp linear rise and exponential decay function to determine the burst timing parameters. The burst profiles show a relatively long tail at lower energies. The broadband time-resolved spectra during the burst periods are successfully modelled with a combination of an absorbed blackbody along with a non-thermal component to account for the persistent emission. From our modelling results, we are able to estimate the maximum apparent emitting area of the blackbody of the neutron star to be $\sim$12.5 km during the peak of the outburst and the maximum distance to the object to be 8.7 kpc. Our findings for the mass accretion rate and the alpha factor indicate the stable burning of hydrogen via a hot CNO cycle during the bursts.

description: We study $\mathcal{N} = 2$ supersymmetric gauge theories on $\mathbb{RP}^2 \times \mathbb{S}^1$ and compute the superconformal index by using the localization technique. We consider not only the round real projective plane $\mathbb{RP}^2$ but also the squashed real projective plane $\mathbb{RP}^2_b$ which turns back to $\mathbb{RP}^2$ by taking a squashing parameter $b$ as $1$. In addition, we found that the result is independent of the squashing parameter $b$. We apply our new superconformal index to the check of the simplest 3d mirror symmetry, i.e. the equivalence between the $\mathcal{N}=2$ SQED and the XYZ model on $\mathbb{RP}^2 \times \mathbb{S}^1$. We prove it by using a mathematical formula called the $q$-binomial theorem. We comment on the $\mathcal{N}=4$ version of mirror symmetry, mirror symmetry via generalized indices, and possibilities of generalizations from mathematical viewpoints.

description: We investigate the purely spatial Lagrangian coordinate transformation from the Lagrangian to the basic Eulerian frame. We demonstrate three techniques for extracting the relativistic displacement field from a given solution in the Lagrangian frame. These techniques are (a) from defining a local set of Eulerian coordinates embedded into the Lagrangian frame; (b) from performing a specific gauge transformation; and (c) from a fully non-perturbative approach based on the ADM split. The latter approach shows that this decomposition is not tied to a specific perturbative formulation for the solution of the Einstein equations. Rather, it can be defined at the level of the non-perturbative coordinate change from the Lagrangian to the Eulerian description. Studying such different techniques is useful because it allows us to compare and develop further the various approximation techniques available in the Lagrangian formulation. We find that one has to solve the gravitational wave equation in the relativistic analysis, otherwise the corresponding Newtonian limit will necessarily contain spurious non-propagating tensor artefacts at second order in the Eulerian frame. We also derive the magnetic part of the Weyl tensor in the Lagrangian frame, and find that it is not only excited by gravitational waves but also by tensor perturbations which are induced through the non-linear frame-dragging. We apply our findings to calculate for the first time the relativistic displacement field, up to second order, for a $Λ$CDM Universe in the presence of a local primordial non-Gaussian component. Finally, we also comment on recent claims about whether mass conservation in the Lagrangian frame is violated.

title: Sag etwas, das sich von selbst versteht, zum erstenmal und du bist unsterblich

description: Die vorliegende Arbeit beschäftigt sich mit der Frage nach Marie von Ebner-Eschenbachs Rolle als Aphoristikerin sowie der Auseinandersetzung mit ihrer Bedeutung als solche in der Literaturgeschichte im deutschsprachigen Raum. Dabei wird anhand des zeitlichen Rahmens von 1880, der ersten selbstständigen Veröffentlichung ihrer Aphorismen, bis heute untersucht, ob und inwiefern sich die Rezeptionsgeschichte verändert hat. Einleitend wird die aphoristische Tradition rekonstruiert, da der Aphorismus als Gattung schwierig zu fassen und in der literaturwissenschaftlichen Forschung umstritten ist. Eine Gegenüberstellung der wichtigsten Definitionskonzepte, das Einbetten des Begriffes selbst in einen historischen Kontext sowie die Entwicklungslinien der Gattung in der deutschsprachigen Literatur bilden die theoretische Grundlage. In einem weiteren Schritt wird ihr aphoristisches Werk analysiert, die französischen Moralisten als ihre Vorbilder behandelt und die formalen, sprachlichen und inhaltlichen Merkmale beleuchtet, die sie als Aphoristikerin von anderen maßgeblich unterscheidet. Der Hauptteil der Arbeit widmet sich der These, dass Marie von Ebner-Eschenbach im 19. Jahrhundert noch zu einer der bedeutendsten Aporistikerinnen zählte, bevor ihre Aphorismen nach ihrem Tod zunehmend in Vergessenheit gerieten, bis sie nicht zuletzt durch die digitalen Medien wieder mehr rezipiert wurden. Anhand der Analyse in der vorliegenden Arbeit hat sich gezeigt, dass bereits zu Lebzeiten ihre Aphorismen sehr wohlwollend rezipiert wurden. Die Literaturgeschichte vernachlässigte ihre Bedeutung für die Gattung zunächst, gestand ihr aber zunehmend eine wichtigere Rolle im Bereich der männerdominierten Aphoristik zu. Heute erfreuen sich aufgrund der Verbreitung in den digitalen Medien eine Vielzahl ihrer Aphorismen einer größeren Rezeption.

description: To gain a more accurate depiction of the lived experience of families, recent studies have explored how parenting and adolescent affect are related in daily life by using daily ecological momentary assessments. Past work reveals that on days when adolescents report more warmth or support of parents, they also report having higher positive and lower negative affect (Bai et al., 2017; Flook, 2011; Janssen, Elzinga et al., 2021; Robles et al., 2016). Given the finding that parents’ perception of own parenting behavior can differ from adolescents’ perception (Hou et al., 2018, 2019; Korelitz & Garber, 2016), multi-informant studies have examined the impact of perceptions of both parents and adolescents as well as differences between them on adolescent affect. Although family systems theories state that family members and their behavior are interrelated and reviews have shown that affect of parents and parenting are related (Dix, 1991; Rueger, 2011), it remains unclear whether and how both adolescent and parent perceptions of parenting and differences relate to parents’ affect. The current study therefore aims to examine whether affective states of both parents and adolescents are related to adolescents’ and parents’ perceptions of parenting and differences between them by using daily reports. Moreover, possible differences between mothers and fathers are assessed.

description: Weak connections between superconductors or superfluids can differ from classical links due to quantum coherence, which allows flow without resistance. Transport properties through such weak links can be described with a single function, the current-phase relationship, which serves as the quantum analog of the current-voltage relationship. Here, we present a technique for inteferometrically measuring the current-phase relationship of superfluid weak links. We interferometrically measure the phase gradient around a ring-shaped superfluid Bose-Einstein condensate (BEC) containing a rotating weak link, allowing us to identify the current flowing around the ring. While our BEC weak link operates in the hydrodynamic regime, this technique can be extended to all types of weak links (including tunnel junctions) in any phase-coherent quantum gas. Moreover, it can also measure the current-phase relationships of excitations. Such measurements may open new avenues of research in quantum transport.

description: We present sharp magnetization jumps and field induced irreversibility in magnetization in multiferroic Y2CoMnO6. Appearance of magnetic relaxation and field sweep rate dependence of magnetization jumps resemble the martensite like scenario and suggests the coexistence of E*-type antiferromagnetic and ferromagnetic phases at low temperatures. In Y2CoMnO6, the critical field required for the sharp jump can be increased or decreased depening on the magnitude and direction of the cooling field; this is remarkably different from manganites or other metamagnetic materials where the critical field increases irrespective of the direction of the field cooling. The cooling field dependence on the sharp magnetization jumps has been described by considering exchange pinning mechanism at the interface, like in exchange bias model.
