  text: The relative motion of three impenetrable particles on a ring, in our case
    two identical fermions and one impurity, is isomorphic to a triangular quantum
    billiard. Depending on the ratio κ of the impurity and fermion masses, the billiards
    can be integrable or non-integrable (also referred to in the main text as chaotic).
    To set the stage, we first investigate the energy level distributions of the billiards
    as a function of 1/κ ∈ [0, 1] and find no evidence of integrable cases beyond
    the limiting values 1/κ = 1 and 1/κ = 0. Then, we use machine learning tools to
    analyze properties of probability distributions of individual quantum states.
    We find that convolutional neural networks can correctly classify integrable and
    non-integrable states. The decisive features of the wave functions are the normalization
    and a large number of zero elements, corresponding to the existence of a nodal
    line. The network achieves typical accuracies of 97%, suggesting that machine
    learning tools can be used to analyze and classify the morphology of probability
    densities obtained in theory or experiment.

  text: In dense biological tissues, cell types performing different roles remain
    segregated by maintaining sharp interfaces. To better understand the mechanisms
    for such sharp compartmentalization, we study the effect of an imposed heterotypic
    tension at the interface between two distinct cell types in a fully 3D Voronoi
    model for confluent tissues. We find that cells rapidly sort and self-organize
    to generate a tissue-scale interface between cell types, and cells adjacent to
    this interface exhibit signature geometric features including nematic-like ordering,
    bimodal facet areas, and registration, or alignment, of cell centers on either
    side of the two-tissue interface. The magnitude of these features scales directly
    with the magnitude of the imposed tension, suggesting that biologists can estimate
    the magnitude of tissue surface tension between two tissue types simply by segmenting
    a 3D tissue. To uncover the underlying physical mechanisms driving these geometric
    features, we develop two minimal, ordered models using two different underlying
    lattices that identify an energetic competition between bulk cell shapes and tissue
    interface area. When the interface area dominates, changes to neighbor topology
    are costly and occur less frequently, which generates the observed geometric features.
