  text: <jats:title>Abstract</jats:title><jats:p>Previous research indicates that
    performing passes with a head fake in basketball leads to increased response initiation
    times and errors as compared to performing a pass without a head fake. These so-called
    fake production costs only occurred when not given the time to mentally prepare
    the deceptive movement. In the current study, we investigated if extensive practice
    could reduce the cognitive costs of producing a pass with head fake. Twenty-four
    basketball novices participated in an experiment on five consecutive days. A visual
    cue prompted participants to play a pass with or without a head fake either to
    the left or right side. The cued action had to be executed after an interstimulus
    interval (ISI) of either 0 ms, 400 ms, 800 ms or 1200 ms, allowing for different
    movement preparation times. Results indicated higher response initiation times
    (ITs) and error rates (ERs) for passes with head fakes for the short preparation
    intervals (ISI 0 ms and 400 ms) on the first day but no difference for the longer
    preparation intervals (ISI 800 ms and 1200 ms). After only one day of practice,
    participants showed reduced fake production costs (for ISI 0 ms) and were even
    able to eliminate these cognitive costs when given time to mentally prepare the
    movement (for ISI 400 ms). Accordingly, physical practice can reduce the cognitive
    costs associated with head-fake generation. This finding is discussed against
    the background of the strengthening of stimulus response associations.</jats:p>

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