text: The lithium niobate–lithium tantalate solid solution’s phase diagram was investigated
using experimental data from differential thermal analysis (DTA) and crystal growth.
We used XRF analysis to determine the elemental composition of the crystals. The
Neumann–Kopp rule provided essential data for the end members lithium niobate
(LN) and lithium tantalate (LT). The heats of fusion of the end members, given
by DTA measurements, are 103 kJ/mol at 1531 K for LN and 289 kJ/mol at 1913 K
for LT. These values were used as input parameters to generate the data. This
data served as the basis for calculating a phase diagram for LN-LT solid solutions.
Finally, based on the experimental data and a thermodynamic solution model, the
Calphad Factsage module optimized the phase diagram. We also generated thermodynamic
parameters for Gibbs’ excess energy of the solid solution. A plot of the segregation
coefficient as a function of Ta concentration was derived from the phase diagram.

text: Augmented (AR) and Virtual Reality (VR) technologies have been applied very
broadly in the recent past. While prior work emphasizes the potential of these
technologies in various application domains, the process of visual attention in
and across the contexts of AR/VR environments is not exhaustively explored yet.
By now, visual attention in AR/VR environments has majorly been studied by means
of overt attention (i.e. saccadic eye movements), self-report, and process-related
visual attention proxies (like reaction time). In this work, we analyze covert
visual attention based on the (psychological) Theory of Visual Attention (TVA),
which allows us to quantify theory-based interpretable properties of the visual
attention process. For example, the TVA allows us to measure the overall processing
speed. We instantiate this TVA-based framework with a 30-participant explorative
within-subjects study. The results show a decisive difference in visual attention
between Reality (i.e. the neutral condition) and Virtual Reality and a weak difference
between Reality and Augmented Reality. We discuss the consequences of our findings
and provide ideas for future studies.

text: Die soziale Ungleichheit im Hochschulsystem nimmt nur sehr langsam ab. Als
eine Begründung gilt die Ausrichtung von Hochschulen an einem akademischen Habitus,
der andere Habitus ausgrenzt und zu Passungsproblematiken führt. Wie diese Passungsproblematiken
aufseiten der Studierenden entstehen ist ein mittlerweile unter suchtes Phänomen.
Die Lehrenden und ihre Praktiken als zentraler Part der Lehr-Lern-Interaktion
werden kaum betrachtet. Dieser Beitrag zeigt anhand einer Sekundärauswertung von
zehn qualitativen Studien Praktiken des Lehrhandelns und der Interaktion zwischen
Lehrenden und Studierenden auf. Analysiert wurden die Studien im Hinblick auf
die Frage wie doing difference stattfindet, also wie durch Lehrpraktiken Studierende
kategorisiert werden und welche Selektions- und Ausgrenzungsprozesse dadurch stattfinden.
Dabei stütze ich mich auf die abgedruckten Interviewpassagen ebenso wie auf die
von den Autorinnen und Autoren gemachten Analysen. Die Lehrpraktiken zeichnen
sich durch eine geringe Diversitätssensibilität mit wenig Hilfsangeboten und eine
starke Befürwortung von Leistungsorientierung und Selektion aus.

text: "We apply principal component analysis (PCA) to a set of electrical
output signals from a commercially available superconducting nanowire single-photon
detector (SNSPD) to investigate their photon-number-resolving capability. We find
that the rising edge as well as the amplitude of the electrical signal have the
most dependence on photon number. Accurately measuring the rising edge while simultaneously
measuring the voltage of the pulse amplitude maximizes the photon-number resolution
of SNSPDs. Using an optimal basis of principal components, we show unambiguous
discrimination between one- and two-photon events, as well as partial resolution
up to five photons. This expands the use case of SNSPDs to photon-counting experiments,
without the need of detector multiplexing architectures.\r\n \r\n

text: "Wir beschreiben den Versuch, »Verständigungskompetenzen« im\r\nSinne von
Ludwig Huber in der Graduiertenförderung zu entwickeln. Verständigung\r\nist für
Huber integraler Bestandteil wissenschaftlicher Erkenntnis. Wissenschaftler:in-\r\nnen
werden aber in die Praktiken ihrer Disziplin hineinsozialisiert; die dabei entstehen-\r\nde
disziplinäre Identität und ihre Selbstverständlichkeiten sind zentral für Teilhabe
am\r\nWissenschaftssystem. Das erschwert Verständigung prinzipiell, insbesondere
das Nach-\r\nvollziehen der Wahrnehmungen und Sinnkonstruktionen der Adressat:innen
des eige-\r\nnen Wissenschaftshandelns. Ausgehend von der Beobachtung, dass Doktorand:innen\r\nihre
Disziplin als selbstverständlichen Zugang zum Gegenstand betrachten, stellen wir\r\ndas
Konzept einer Sommerschule vor, das darauf zielt, die Abstraktion von der eigenen\r\ndisziplinären
Perspektive zu ermöglichen, Systemwissen fördert und Verständigungs-\r\nprozesse
anstößt."

text: Samples of dielectric optical waveguides of rib or strip type in thin-film
lithium niobate (TFLN) technology are characterized with respect to their optical
loss using the Fabry-Pérot method. Attributing the losses mainly to sidewall roughness,
we employ a simple perturbational procedure, based on rigorously computed mode
profiles of idealized channels, to estimate the attenuation for waveguides with
different cross sections. A single fit parameter suffices for an adequate modelling
of the effect of the waveguide geometry on the loss levels.

text: 'We explore the polarization hysteretic behaviour and field-dependent permittivity
of ferroelectric-dielectric 2D materials formed by random dispersions of low permittivity
inclusions in a ferroelectric matrix, using finite element simulations. We show
how the degree of impenetrability of dielectric inclusions plays a substantial
role in controlling the coercive field, remnant and saturation polarizations of
the homogenized materials. The results highlight the significance of the degree
of impenetrability of inclusion in tuning the effective polarization properties
of such ferroelectric composites: coercive field drops significantly as percolation
threshold is attained and remnant polarization decreases faster than a linear
decay.'

text: AbstractA comprehensive investigation of
the potential of aqueous glucosamine solutions as an eco‐friendly solvent for
CO2 capture was performed. It includes an experimental study
in a pilot plant setup and a theoretical analysis with a rate‐based model. The
model was validated against the measured column profiles of temperature and CO2
concentration in both liquid and gas phases. Model‐based parameter sensitivity
studies revealed inherent challenges for an effective absorption process. A slow
reaction rate and suboptimal chemical equilibrium conditions were identified as
key limitations, restricting the absorption efficiency and CO2
loading capacity of the glucosamine solution. Furthermore, an analysis of the
dissociation constant of this novel absorbent was performed and its significance
with respect to the (limited) performance, capability, and efficiency evaluation
was highlighted.

text: "Dieser Beitrag stellt zwei Seminarkonzeptionen vor, in welchen technisch-didaktische\r\nVorüberlegungen,
Lehr-/Lernaktivitäten und Prüfmodalitäten unter der Bedingung\r\nvon Digitalität
skizziert werden. Es wird das digitale wissenschaftliche Lesen und\r\nSchreiben
ins Zentrum der Interaktion mit digitalen Technologien gestellt. In den Se\r\nminaren
wurden von Studierenden selbstständig Daten (Text) gesammelt, ausgewertet\r\nund
geclustert. Die kollaborative cloudbasierte Speicherung der Seminardaten, der\r\nEinbezug
einer geteilten Literaturdatenbank sowie der Einsatz der Notizsoftware Obsi\r\ndian.md
beim gemeinschaftlichen wissenschaftlichen Lesen und Schreiben wurden er\r\nprobt.
Zentrale Herausforderung war die Doppelrolle der Dozierenden (Verantwor\r\ntung
für Lehr-/Lernsetting vs. Techniksupport). Herausragend war die Partizipation\r\nund
Verantwortungsübernahme der Studierenden in den Seminarsitzungen und beim\r\nPeersupport."

text: In dieser Arbeit werden Untersuchungen zur sauerstoffabhängigen Photolumineszenz
von Zink-Zinn-Oxid-Partikeln präsentiert, welche perspektivisch für die optische
Sauerstoffdetektion eingesetzt werden sollen. Zink-Zinn-Oxid zeigt eine sauerstoffabhängige
Photolumineszenz im sichtbaren Spektralbereich und wird hier als eine photostabile
Alternative zu den kommerziell verfügbaren metallorganischen Verbindungen vorgestellt.
Der Fokus liegt dabei auf dem Einfluss der Temperatur auf die Sauerstoffsensitivität
der Photolumineszenz. Wir zeigen, dass bereits leichte Temperaturerhöhungen zu
einer signifikanten Verbesserung der Sauerstoffsensitivität der Photolumineszenz
führen und gleichzeitig die Signalqualität erhöhen.

text: 'Diese Studie widmet sich der Frage, inwiefern die schriftbildliche Gestaltung
(Zeichengestaltung, Anordnung, Hervorhebung etc.) grammatisch bedeutsam sein kann.
Zur Beantwortung wird ein erweiterter kognitiv-grammatischer Ansatz gewählt und
ein selbsterstelltes Korpus aus 1.317 Fotos von Lebensmittelverpackungen mithilfe
der Software MAXQDA analysiert. Das Analyseverfahren basiert auf einer innovativen
Kombination aus musterorientierter Kollektionsanalyse und der Adaption grammatischer
Proben. Die Untersuchung offenbart erstens, dass Markennamen wie ''Coca-Cola'',
''nutella'' etc. multimodale Konstruktionen mit konstitutiver Schriftbildlichkeit
sein können, sofern deren Gestaltung kognitiv verankert und interindividuell konventionell
ist. Zweitens wird für Warennamen wie ''GUT & GÜNSTIG Knäckebrot Sesam'' etc.
die Wirkung diagrammatischer Ikonizität erarbeitet, wonach die musterhafte schriftbildliche
Gestaltung die Komposition der einzelnen Komponenten eines Warennamens vereindeutigt.
Drittens werden Zusammensetzungen mit nicht-verbalen Prädikaten wie ''mit 11%
Sesam'', ''ohne Rosinen'' etc. als multimodale Konstruktionen herausgearbeitet,
bei denen die musterhafte gestalterische Verknüpfung das Verständnis ebenfalls
maßgeblich beeinflusst. '

text: "We introduce a method based on Gaussian process regression to identify discrete
variational principles from observed solutions of a field theory. The method is
based on the data-based identification of a discrete Lagrangian density. It is
a geometric machine learning technique in the sense that the variational structure
of the true field theory is reflected in the data-driven model by design. We provide
a rigorous convergence statement of the method. The proof circumvents challenges
posed by the ambiguity of discrete Lagrangian densities in the inverse problem
of variational calculus.\r\nMoreover, our method can be used to quantify model
uncertainty in the equations of motions and any linear observable of the discrete
field theory. This is illustrated on the example of the discrete wave equation
and Schrödinger equation.\r\nThe article constitutes an extension of our previous
article arXiv:2404.19626 for the data-driven identification of (discrete) Lagrangians
for variational dynamics from an ode setting to the setting of discrete pdes."

We introduce a method based on Gaussian process regression to identify discrete
variational principles from observed solutions of a field theory. The method is based on the data-based identification of a discrete Lagrangian density. It is a geometric machine learning technique in the sense that the variational structure of the true field theory is reflected in the data-driven model by design.
We provide a rigorous convergence statement of the method.
The proof circumvents challenges posed by the ambiguity of discrete Lagrangian densities in the inverse problem of variational calculus.
Moreover, our method can be used to quantify model uncertainty in the equations of motions and any linear observable of the discrete field theory.
This is illustrated on the example of the discrete wave equation and Schrödinger equation.
The article constitutes an extension of our previous article for the data-driven identification of (discrete) Lagrangians for variational dynamics from an ode setting to the setting of discrete pdes.
