text: 'We introduce the concept of a k-token signed graph and study some of its
combinatorial and algebraic properties. We prove that two switching isomorphic
signed graphs have switching isomorphic token graphs. Moreover, we show that the
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: "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 $\\mathsf{QCPH}\\subseteq\r\n\\mathsf{pureQPH} \\subseteq \\mathsf{EXP}^{\\mathsf{PP}}$."
