  text: 'A face in a curve arrangement is called popular if it is bounded by the same
    curve multiple times. Motivated by the automatic generation of curved nonogram
    puzzles, we investigate possibilities to eliminate the popular faces in an arrangement
    by inserting a single additional curve. This turns out to be NP-hard; however,
    it becomes tractable when the number of popular faces is small: We present a probabilistic
    FPT-approach in the number of popular faces.'

  text: Precision sensing and manipulation of milligram-scale mechanical oscillators
    has attracted growing interest in the fields of table-top explorations of gravity
    and tests of quantum mechanics at macroscopic scales. Torsional oscillators present
    an opportunity in this regard due to their remarked isolation from environmental
    noise. For torsional motion, an effective employment of optical cavities to enhance
    optomechanical interactions—as already established for linear oscillators—so far
    faced certain challenges. Here, we propose a concept for sensing and manipulating
    torsional motion, where exclusively the torsional rotations of a pendulum are
    mapped onto the path length of a single two-mirror optical cavity. The concept
    inherently alleviates many limitations of previous approaches. A proof-of-principle
    experiment is conducted with a rigidly controlled pendulum to explore the sensing
    aspects of the concept and to identify practical limitations in a potential state-of-the
    art setup. Based on this study, we anticipate development of precision torque
    sensors utilizing torsional pendulums that can support sensitivities below 10−19Nm/√Hz,
    while the motion of the pendulums are dominated by quantum radiation pressure
    noise at sub-microwatts of incoming laser power. These developments will provide
    horizons for experiments at the interface of quantum mechanics and gravity.
