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 $\\mathsf{QCPH}\\subseteq\r\n\\mathsf{pureQPH} \\subseteq \\mathsf{EXP}^{\\mathsf{PP}}$."

text: 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.

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