AB - Despite the fundamental role the Quantum Satisfiability (QSAT) problem has
played in quantum complexity theory, a central question remains open: At which
local dimension does the complexity of QSAT transition from "easy" to "hard"?
Here, we study QSAT with each constraint acting on a $k$-dimensional and
$l$-dimensional qudit pair, denoted $(k,l)$-QSAT. Our first main result shows
that, surprisingly, QSAT on qubits can remain $\mathsf{QMA}_1$-hard, in that
$(2,5)$-QSAT is $\mathsf{QMA}_1$-complete. In contrast, $2$-SAT on qubits is
well-known to be poly-time solvable [Bravyi, 2006]. Our second main result
proves that $(3,d)$-QSAT on the 1D line with $d\in O(1)$ is also
$\mathsf{QMA}_1$-hard. Finally, we initiate the study of 1D $(2,d)$-QSAT by
giving a frustration-free 1D Hamiltonian with a unique, entangled ground state.
Our first result uses a direct embedding, combining a novel clock
construction with the 2D circuit-to-Hamiltonian construction of [Gosset, Nagaj,
2013]. Of note is a new simplified and analytic proof for the latter (as
opposed to a partially numeric proof in [GN13]). This exploits Unitary Labelled
Graphs [Bausch, Cubitt, Ozols, 2017] together with a new "Nullspace Connection
Lemma", allowing us to break low energy analyses into small patches of
projectors, and to improve the soundness analysis of [GN13] from
$\Omega(1/T^6)$ to $\Omega(1/T^2)$, for $T$ the number of gates. Our second
result goes via black-box reduction: Given an arbitrary 1D Hamiltonian $H$ on
$d'$-dimensional qudits, we show how to embed it into an effective null-space
of a 1D $(3,d)$-QSAT instance, for $d\in O(1)$. Our approach may be viewed as a
weaker notion of "simulation" (\`a la [Bravyi, Hastings 2017], [Cubitt,
Montanaro, Piddock 2018]). As far as we are aware, this gives the first
"black-box simulation"-based $\mathsf{QMA}_1$-hardness result, i.e. for
frustration-free Hamiltonians.

AB - When it comes to NP, its natural definition, its wide applicability across scientific disciplines, and its timeless relevance, the writing is on the wall: There can be only one. Quantum NP, on the other hand, is clearly the apple that fell far from the tree of NP. Two decades since the first definitions of quantum NP started rolling in, quantum complexity theorists face a stark reality: There's QMA, QCMA, QMA1, QMA(2), StoqMA, and NQP. In this article aimed at a general theoretical computer science audience, I survey these various definitions of quantum NP, their strengths and weaknesses, and why most of them, for better or worse, actually appear to fit naturally into the complexity zoo.

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

AB - We show how to learn discrete field theories from observational data of fields on a space-time lattice. For this, we train a neural network model of a discrete Lagrangian density such that the discrete Euler--Lagrange equations are consistent with the given training data. We, thus, obtain a structure-preserving machine learning architecture. Lagrangian densities are not uniquely defined by the solutions of a field theory. We introduce a technique to derive regularisers for the training process which optimise numerical regularity of the discrete field theory. Minimisation of the regularisers guarantees that close to the training data the discrete field theory behaves robust and efficient when used in numerical simulations. Further, we show how to identify structurally simple solutions of the underlying continuous field theory such as travelling waves. This is possible even when travelling waves are not present in the training data. This is compared to data-driven model order reduction based approaches, which struggle to identify suitable latent spaces containing structurally simple solutions when these are not present in the training data. Ideas are demonstrated on examples based on the wave equation and the Schrödinger equation.

AB - Broadband coherent anti-Stokes Raman scattering (BCARS) is a powerful spectroscopy method combining high signal intensity with spectral sensitivity, enabling rapid imaging of heterogeneous samples in biomedical research and, more recently, in crystalline materials. However, BCARS encounters spectral distortion due to a setup-dependent non-resonant background (NRB). This study assesses BCARS reproducibility through a round robin experiment using two distinct BCARS setups and crystalline materials with varying structural complexity, including diamond, 6H-SiC, KDP, and KTP. The analysis compares setup-specific NRB correction procedures, detected and NRB-removed spectra, and mode assignment. We determine the influence of BCARS setup parameters like pump wavelength, pulse width, and detection geometry and provide a practical guide for optimizing BCARS setups for solid-state applications.

AB - 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.

AB - What is the power of polynomial-time quantum computation with access to an NP
oracle? In this work, we focus on two fundamental tasks from the study of
Boolean satisfiability (SAT) problems: search-to-decision reductions, and
approximate counting. We first show that, in strong contrast to the classical
setting where a poly-time Turing machine requires $\Theta(n)$ queries to an NP
oracle to compute a witness to a given SAT formula, quantumly $\Theta(\log n)$
queries suffice. We then show this is tight in the black-box model - any
quantum algorithm with "NP-like" query access to a formula requires
$\Omega(\log n)$ queries to extract a solution with constant probability.
Moving to approximate counting of SAT solutions, by exploiting a quantum link
between search-to-decision reductions and approximate counting, we show that
existing classical approximate counting algorithms are likely optimal. First,
we give a lower bound in the "NP-like" black-box query setting: Approximate
counting requires $\Omega(\log n)$ queries, even on a quantum computer. We then
give a "white-box" lower bound (i.e. where the input formula is not hidden in
the oracle) - if there exists a randomized poly-time classical or quantum
algorithm for approximate counting making $o(log n)$ NP queries, then
$\text{BPP}^{\text{NP}[o(n)]}$ contains a $\text{P}^{\text{NP}}$-complete
problem if the algorithm is classical and $\text{FBQP}^{\text{NP}[o(n)]}$
contains an $\text{FP}^{\text{NP}}$-complete problem if the algorithm is
quantum.

AB - 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.
Im 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.

AB - We propose an indicator for detecting anomalous stock market valuation in real time such that market participants receive timely signals so as to be able to take stabilizing action. Unlike existing approaches, our anomaly indicator introduces three methodological novelties. First, we use an endogenous, purely data-driven, nonparametric trend identification method to separate long-term market movements from more short-term ones. Second, we apply SETAR models that allow for asymmetric expansions and contractions around the long-term trend and find systematic stock price cycles. Third, we implement these findings in our indicator and conduct real-time market forecasts, which have so far been neglected in the literature. Applications of our indicator using monthly S&P 500 stock data from 1970 to the end of 2022 show that short-term anomalous market movements can be identified in real time up to one year ahead. We predict all major anomalies, including the 1987 Bubble and the initial phase of the Financial Crisis that began in 2007. In total, our anomaly indicator identifies more than 80% of all – even minor – anomalous episodes. Thus, smoothing market exaggerations through early signaling seems possible.

AB - Abstract
Background
An infection with SARS-CoV-2 can lead to a variety of symptoms and complications, which can impair athletic activity.
Objective
We aimed to assess the clinical symptom patterns, diagnostic findings, and the extent of impairment in sport practice in a large cohort of athletes infected with SARS-CoV-2, both initially after infection and at follow-up. Additionally, we investigated whether baseline factors that may contribute to reduced exercise tolerance at follow-up can be identified.
Methods
In this prospective, observational, multicenter study, we recruited German COVID elite-athletes (cEAs, n = 444) and COVID non-elite athletes (cNEAs, n = 481) who tested positive for SARS-CoV-2 by PCR (polymerase chain reaction test). Athletes from the federal squad with no evidence of SARS-CoV-2 infection served as healthy controls (EAcon, n = 501). Questionnaires were used to assess load and duration of infectious symptoms, other complaints, exercise tolerance, and duration of training interruption at baseline and at follow-up 6 months after baseline. Diagnostic tests conducted at baseline included resting and exercise electrocardiogram (ECG), echocardiography, spirometry, and blood analyses.
Results
Most acute and infection-related symptoms and other complaints were more prevalent in cNEA than in cEAs. Compared to cEAs, EAcon had a low symptom load. In cNEAs, female athletes had a higher prevalence of complaints such as palpitations, dizziness, chest pain, myalgia, sleeping disturbances, mood swings, and concentration problems compared to male athletes (p < 0.05). Until follow-up, leading symptoms were drop in performance, concentration problems, and dyspnea on exertion. Female athletes had significantly higher prevalence for symptoms until follow-up compared to male. Pathological findings in ECG, echocardiography, and spirometry, attributed to SARS-CoV-2 infection, were rare in infected athletes. Most athletes reported a training interruption between 2 and 4 weeks (cNEAs: 52.9%, cEAs: 52.4%), while more cNEAs (27.1%) compared to cEAs (5.1%) had a training interruption lasting more than 4 weeks (p < 0.001). At follow-up, 13.8% of cNEAs and 9.9% of cEAs (p = 0.24) reported their current exercise tolerance to be under 70% compared to pre-infection state. A persistent loss of exercise tolerance at follow-up was associated with persistent complaints at baseline, female sex, a longer break in training, and age > 38 years. Periodical dichotomization of the data set showed a higher prevalence of infectious symptoms such as cough, sore throat, and coryza in the second phase of the pandemic, while a number of neuropsychiatric symptoms as well as dyspnea on exertion were less frequent in this period.
Conclusions
Compared to recreational athletes, elite athletes seem to be at lower risk of being or remaining symptomatic after SARS-CoV-2 infection. It remains to be determined whether persistent complaints after SARS-CoV-2 infection without evidence of accompanying organ damage may have a negative impact on further health and career in athletes. Identifying risk factors for an extended recovery period such as female sex and ongoing neuropsychological symptoms could help to identify athletes, who may require a more cautious approach to rebuilding their training regimen.

AB - 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.
