text: Data-driven models for nonlinear dynamical systems based on approximating
the underlying Koopman operator or generator have proven to be successful tools
for forecasting, feature learning, state estimation, and control. It has become
well known that the Koopman generators for control-affine systems also have affine
dependence on the input, leading to convenient finite-dimensional bilinear approximations
of the dynamics. Yet there are still two main obstacles that limit the scope of
current approaches for approximating the Koopman generators of systems with actuation.
First, the performance of existing methods depends heavily on the choice of basis
functions over which the Koopman generator is to be approximated; and there is
currently no universal way to choose them for systems that are not measure preserving.
Secondly, if we do not observe the full state, we may not gain access to a sufficiently
rich collection of such functions to describe the dynamics. This is because the
commonly used method of forming time-delayed observables fails when there is actuation.
To remedy these issues, we write the dynamics of observables governed by the Koopman
generator as a bilinear hidden Markov model, and determine the model parameters
using the expectation-maximization (EM) algorithm. The E-step involves a standard
Kalman filter and smoother, while the M-step resembles control-affine dynamic
mode decomposition for the generator. We demonstrate the performance of this method
on three examples, including recovery of a finite-dimensional Koopman-invariant
subspace for an actuated system with a slow manifold; estimation of Koopman eigenfunctions
for the unforced Duffing equation; and model-predictive control of a fluidic pinball
system based only on noisy observations of lift and drag.

text: Superconducting nanowire single-photon detectors (SNSPDs) have been
widely used to study the discrete nature of quantum states of light in the form
of photon-counting experiments. We show that SNSPDs can also be used to study
continuous variables of optical quantum states by performing homodyne detection
at a bandwidth of 400 kHz. By measuring the interference of a continuous-wave
field of a local oscillator with the field of the vacuum state using two SNSPDs,
we show that the variance of the difference in count rates is linearly proportional
to the photon flux of the local oscillator over almost five orders of magnitude.
The resulting shot-noise clearance of (46.0 ± 1.1) dB is the highest reported
clearance for a balanced optical homodyne detector, demonstrating their potential
for measuring highly squeezed states in the continuous-wave regime. In addition,
we measured a CMRR = 22.4 dB. From the joint click counting statistics, we also
measure the phase-dependent quadrature of a weak coherent state to demonstrate
our device’s functionality as a homodyne detector.

text: In order to standardize spray flame synthesis (SFS) studies, intensive work
has been done in recent years on the design of burner types. Thus, in 2019, the
so-called SpraySyn1 burner was introduced (SS1), which was subsequently characterized
in numerical and experimental studies. Based on this research, a modification
of the nozzle design was proposed, which has now been considered in the successor
model, SpraySyn2 (SS2). As little is known about the effect of the nozzle adaptation
on the particle formation, we operated both burners under identical operating
conditions to produce maghemite. The final powder comparison showed that SS2 yielded
considerable higher specific surface areas (associated with smaller primary particle
sizes), lower polydispersity, and higher phase purity. To obtain further information
on the size distributions of aggregates and agglomerates generated by SS2, aerosol
samples were extracted by hole in a tube (HIAT) sampling and characterized by
scanning mobility particle sizing (SMPS). Samples were extracted along the centerline
at different heights above the burner (HAB) above the visible flame tip (>7 cm),
and quenching experiments were performed to extract the aerosol samples at different
dilution rates. Thereby, it was demonstrated that performing detailed quenching
experiments is crucial for obtaining representative HIAT-SMPS data. In particular,
agglomerates/aggregate sizes were overestimated by up to ~70 % if samples were
not sufficiently diluted. If sufficient dilution was applied, distribution widths
and mean particle mobility diameters were determined with high accuracy (sample
standard derivation <5 %). Our data suggested the evolution of primary particle
sizes was mostly completed <7 cm HAB and it was shown aggregates/agglomerates
present above the visible flame were compact in structure (non- fractal). The
mean diameter of the particle ensemble grew along the centerline from 6.9 nm (7
cm) to 11.4 nm (15 cm), while distribution widths grew from 1.42 to 1.52.

text: "Die Extrusion stellt das mengenmäßig dominante Verarbeitungsverfahren für
thermoplastische Kunststoffe dar. Daher gibt es starke Bestrebungen in diesem
Bereich hin zu einer höheren Wirtschaftlichkeit, welche beispielsweise durch höheren
Massedurchsatz bei gleichbleibender Maschinengröße erreicht werden kann, oder
aber auch im Hinblick auf eine Kreislaufwirtschaft die Bestrebung hin zu einer
materialschonenden Verarbeitung. Beide Bestrebungen erfordern spezielle Schneckenkonzepte.
Hierunter fallenWave- Schnecken, welche in beiden Bereichen ein vorteilhaftes
Prozessverhalten aufzeigen sollen. Die Auslegung von Wave-Schnecken erfordert
jedoch ein stärkeres Verständnis über das geometrieabhängige Prozessverhalten
in der Extrusion. \r\nIm Rahmen der Dissertation werden zwei Themengebiete angegangen.
Das erste Thema ist die Herleitung einer Methode zur Charakterisierung des Abbauverhaltens
von Thermoplasten sowie die Nutzung der Charakterisierung als Vorhersagemodell.
Das zweite Thema behandelt die Auslegung von Wave-Schnecken basierend auf numerischen
Simulationen samt Validierung anhand von sieben Energy-Transfer-Schnecken im Vergleich
zu drei konventionellen Schnecken. Hierbei werden unter anderem der Materialabbau,
die thermische und die stoffliche Homogenität betrachtet, um ein umfassendes Bild
über das Prozessverhalten der Schnecken zu schaffen. Die vorgestellten Untersuchungen
dienen schlussendlich zu einer Bestätigung des vorteilhaften Prozessverhaltens
von Wave-Schnecken."

text: "The extrusion process is the dominant processing method for thermoplastics
in terms of quantity. For this reason, there are strong efforts in this area towards
greater economic efficiency, which can be achieved, for example, through higher
mass throughput with the same machine size, or, with regard to a circular economy,
towards material-preserving processing. Both endeavours require special screw
concepts. These include wave screws, which should demonstrate advantageous process
behaviour in both areas. However, the design of wave screws requires a better
understanding of the geometry-dependent process behaviour in extrusion. \r\nTwo
topics are addressed in the dissertation. The first topic is the derivation of
a method to characterise the degradation behaviour of thermoplastics and the use
of the characterisation as a predictive model. The second topic deals with the
design of wave screws based on numerical simulations including validation using
seven energy transfer screws in comparison to three conventional screws. Among
other things, the material degradation, the thermal and the material homogeneity
are considered in order to create a comprehensive picture of the process behaviour
of the screws. The presented investigations ultimately serve to confirm the advantageous
process behaviour of wave screws."

text: This study investigates the teaching methods that future teachers of German
as a foreign language use in cultural mediation. Utilizing a qualitative and hermeneutic
approach, it analyzes data from a teacher-training module of the International
Master's in German as a Foreign/Second Language that Friedrich Schiller University
Jena in Germany offers. Participants taught an online course to students from
a Japanese university, which focused on cultural learning. Within the teacher
training module, the participants discussed their lesson plans, conducted classes,
and subsequently reflected on their teaching practices by exploring and critiquing
the practical application of their teaching skills. The analysis, which was conducted
using qualitative evaluative content analysis following Kuckartz's (2018) approach,
revealed a preference for distributive/instructive methods, with some recognition
of interactive and collaborative methods. A tendency towards both repetitive and
reflective practices was evident, with a predominant focus on content that was
specific to a supposed target culture rather than intercultural or transcultural
content. The study highlights the need to balance knowledge transmission with
the development of critical and reflective skills in cultural mediation. It emphasizes
the importance of incorporating collaborative and interactive methods, which promote
a critical attitude that is necessary in language teachers and learners. In conclusion,
this study advocates adaptive and reflective teaching as an essential component
in the training of future language teachers in globalized contexts.

text: "Ultraschallsysteme für das Herstellen für Bond- und Schweißverbindungen in
der Halbleiterfertigung zeigen auf Grund des Betriebes unter hohen Anregungsniveaus
nichtlineare Materialeigenschaften. Dabei wirken unterschiedliche Einflussfaktoren
auf die elektrischen Eigenschaften und die mechanischen Übertragungscharakteristiken
der Ultraschallsysteme ein. Die Herausforderungen ein solches geprägtes System
auszulegen oder effizient und zuverlässig zu betreiben, sind aufgrund der Nichtlinearitäten
relativ groß.\r\nDa für die Beschreibung der nichtlinearen Materialbeziehungen
nur wenige Modelle und kaum quantitative Angaben vorliegen, werden die komplexen
Wechselwirkungen von Materialparametern, Geometrie und Vorspannung des Schwingers,
Betriebsgrößen (Strom, Spannung), Temperatur und Prozesslasten durch systematische
Untersuchungen von Keramiken und Langevin-Schwingern messtechnisch erfasst. Aus
den Messergebnissen werden einerseits eindimensionale Modelle für Voruntersuchungen
als auch vollständige Materialparametersätze für die Simulation mittels dreidimensionaler
FE-Modelle hergeleitet.\r\nEine Methodik zur Ermittlung der Materialparameter
und ein auf iterativen Simulationen von FE-Modellen basierendes Werkzeug zur Simulation
der komplexen Wechselwirkungen werden vorgestellt. Anhand eines exemplarischen
Ultraschallsystems wird gezeigt, dass die Wirkungen temperaturbedingter Vorspannungsverluste,
Änderungen des elektrischen Klemmenverhaltens und Amplituden- und Frequenzänderungen
während des Betriebes bei großen Amplituden und Prozesslasten durch die Variationen
des Keramikvolumens und der Keramikposition positiv beeinflusst werden können."

combinatorial and algebraic properties. We prove that two switching isomorphic

Laplacian spectrum of a balanced signed graph is contained in the Laplacian spectra
of its k-token signed graph. Besides, we introduce and study the unbalance level
of a signed graph, which is a new parameter that measures how far a signed graph
is from being balanced. Moreover, we study the relation between the frustration
index and the unbalance level of signed graphs and their token signed graphs. '

text: AbstractBackgroundReal‐world
problems are important in math instruction, but they do not necessarily trigger
students' task motivation. Personalizing real‐world problems by (1) matching problems
to students' shared living environment (context personalization) and (2) asking
students to pose their own problems (active personalization) might be two interventions
to increase students' task motivation.AimIn
the current study, we investigated the effects of context personalization and
active personalization on students' self‐efficacy expectations, intrinsic value,
attainment value, utility value, and cost.SampleThe
participants were 28 fifth‐ and sixth‐grade students who voluntarily took part
in a six‐month afterschool program in which they posed problems with the aim of
creating a math walk in their hometown.MethodUsing
a within‐subjects design, at the end of the afterschool program, the students
rated their self‐efficacy expectations and task values for four self‐developed
problems associated with their hometown, four peer‐developed problems associated
with their hometown, and four instructor‐provided problems associated with unfamiliar
locations.ResultsStudents
reported higher self‐efficacy expectations, intrinsic value, attainment value,
and utility value for active‐personalized than non‐personalized problems. To a
lesser extent, context personalization promoted intrinsic value and attainment
value. No effect was found for cost.ConclusionsActive
personalization (i.e. asking students to pose their own real‐world problems) is
suited to enhance students' task motivation, specifically their self‐efficacy
expectations, intrinsic value, attainment value, and utility value. Context personalization
still boosts students' intrinsic value and attainment value. Implementation in
classroom instruction is discussed.

text: "Given a real semisimple connected Lie group $G$ and a discrete torsion-free\r\nsubgroup
$\\Gamma < G$ we prove a precise connection between growth rates of the\r\ngroup
$\\Gamma$, polyhedral bounds on the joint spectrum of the ring of\r\ninvariant
differential operators, and the decay of matrix coefficients. In\r\nparticular,
this allows us to completely characterize temperedness of\r\n$L^2(\\Gamma\\backslash
G)$ in this general setting."

text: "Abstract\r\n Lithium niobate
has emerged as a promising platform for integrated quantum optics, enabling efficient
generation, manipulation, and detection of quantum states of light. However, integrating
single-photon detectors requires cryogenic operating temperatures, since the best
performing detectors are based on narrow superconducting wires. While previous
studies have demonstrated the operation of quantum light sources and electro-optic
modulators in LiNbO3 at cryogenic temperatures, the thermal
transition between room temperature and cryogenic conditions introduces additional
effects that can significantly influence device performance. In this paper, we
investigate the generation of pyroelectric charges and their impact on the optical
properties of lithium niobate waveguides when changing from room temperature to
25 K, and vice versa. We measure the generated pyroelectric charge flow and correlate
this with fast changes in the birefringence acquired through the Sénarmont-method.
Both electrical and optical influence of the pyroelectric effect occur predominantly
at temperatures above 100 K."

text: "Despite the fundamental role the Quantum Satisfiability (QSAT) problem has\r\nplayed
in quantum complexity theory, a central question remains open: At which\r\nlocal
dimension does the complexity of QSAT transition from \"easy\" to \"hard\"?\r\nHere,
we study QSAT with each constraint acting on a $k$-dimensional and\r\n$l$-dimensional
qudit pair, denoted $(k,l)$-QSAT. Our first main result shows\r\nthat, surprisingly,
QSAT on qubits can remain $\\mathsf{QMA}_1$-hard, in that\r\n$(2,5)$-QSAT is $\\mathsf{QMA}_1$-complete.
In contrast, $2$-SAT on qubits is\r\nwell-known to be poly-time solvable [Bravyi,
2006]. Our second main result\r\nproves that $(3,d)$-QSAT on the 1D line with
$d\\in O(1)$ is also\r\n$\\mathsf{QMA}_1$-hard. Finally, we initiate the study
of 1D $(2,d)$-QSAT by\r\ngiving a frustration-free 1D Hamiltonian with a unique,
entangled ground state.\r\n Our first result uses a direct embedding, combining
a novel clock\r\nconstruction with the 2D circuit-to-Hamiltonian construction
of [Gosset, Nagaj,\r\n2013]. Of note is a new simplified and analytic proof for
the latter (as\r\nopposed to a partially numeric proof in [GN13]). This exploits
Unitary Labelled\r\nGraphs [Bausch, Cubitt, Ozols, 2017] together with a new \"Nullspace
Connection\r\nLemma\", allowing us to break low energy analyses into small patches
of\r\nprojectors, and to improve the soundness analysis of [GN13] from\r\n$\\Omega(1/T^6)$
to $\\Omega(1/T^2)$, for $T$ the number of gates. Our second\r\nresult goes via
black-box reduction: Given an arbitrary 1D Hamiltonian $H$ on\r\n$d'$-dimensional
qudits, we show how to embed it into an effective null-space\r\nof a 1D $(3,d)$-QSAT
instance, for $d\\in O(1)$. Our approach may be viewed as a\r\nweaker notion of
\"simulation\" (\\`a la [Bravyi, Hastings 2017], [Cubitt,\r\nMontanaro, Piddock
2018]). As far as we are aware, this gives the first\r\n\"black-box simulation\"-based
$\\mathsf{QMA}_1$-hardness result, i.e. for\r\nfrustration-free Hamiltonians."

text: "The Polynomial-Time Hierarchy ($\\mathsf{PH}$) is a staple of classical\r\ncomplexity
theory, with applications spanning randomized computation to circuit\r\nlower
bounds to ''quantum advantage'' analyses for near-term quantum computers.\r\nQuantumly,
however, despite the fact that at least \\emph{four} definitions of\r\nquantum
$\\mathsf{PH}$ exist, it has been challenging to prove analogues for\r\nthese
of even basic facts from $\\mathsf{PH}$. This work studies three\r\nquantum-verifier
based generalizations of $\\mathsf{PH}$, two of which are from\r\n[Gharibian,
Santha, Sikora, Sundaram, Yirka, 2022] and use classical strings\r\n($\\mathsf{QCPH}$)
and quantum mixed states ($\\mathsf{QPH}$) as proofs, and one\r\nof which is new
to this work, utilizing quantum pure states\r\n($\\mathsf{pureQPH}$) as proofs.
We first resolve several open problems from\r\n[GSSSY22], including a collapse
theorem and a Karp-Lipton theorem for\r\n$\\mathsf{QCPH}$. Then, for our new class
$\\mathsf{pureQPH}$, we show one-sided\r\nerror reduction for $\\mathsf{pureQPH}$,
as well as the first bounds relating\r\nthese quantum variants of $\\mathsf{PH}$,
namely $\\mathsf{QCPH}\\subseteq\r\n\\mathsf{pureQPH} \\subseteq \\mathsf{EXP}^{\\mathsf{PP}}$."
