text: 'Computer vision systems for automatic image categorization have become accurate
and reliable enough that they can run continuously for days or even years as components
of real-world commercial applications. A major open problem in this context, however,
is quality control. Good classification performance can only be expected if systems
run under the specific conditions, in particular data distributions, that they
were trained for. Surprisingly, none of the currently used deep network architectures
have a built-in functionality that could detect if a network operates on data
from a distribution it was not trained for, such that potentially a warning to
the human users could be triggered. In this work, we describe KS(conf), a procedure
for detecting such outside of specifications (out-of-specs) operation, based on
statistical testing of the network outputs. We show by extensive experiments using
the ImageNet, AwA2 and DAVIS datasets on a variety of ConvNets architectures that
KS(conf) reliably detects out-of-specs situations. It furthermore has a number
of properties that make it a promising candidate for practical deployment: it
is easy to implement, adds almost no overhead to the system, works with all networks,
including pretrained ones, and requires no a priori knowledge of how the data
distribution could change. '

text: We present a thermodynamically based approach to the design of models for
viscoelastic fluids with stress diffusion effect. In particular, we show how to
add a stress diffusion term to some standard viscoelastic rate-type models (Giesekus,
FENE-P, Johnson–Segalman, Phan-Thien–Tanner and Bautista–Manero–Puig) so that
the resulting models with the added stress diffusion term are thermodynamically
consistent in the sense that they obey the first and the second law of thermodynamics.
We point out the potential applications of the provided thermodynamical background
in the study of flows of fluids described by the proposed models.

text: We investigate the ground-state energy of a one-dimensional Fermi gas with
two bosonic impurities. We consider spinless fermions with no fermion-fermion
interactions. The fermion-impurity and impurity-impurity interactions are modeled
with Dirac delta functions. First, we study the case where impurity and fermion
have equal masses, and the impurity-impurity two-body interaction is identical
to the fermion-impurity interaction, such that the system is solvable with the
Bethe ansatz. For attractive interactions, we find that the energy of the impurity-impurity
subsystem is below the energy of the bound state that exists without the Fermi
gas. We interpret this as a manifestation of attractive boson-boson interactions
induced by the fermionic medium, and refer to the impurity-impurity subsystem
as an in-medium bound state. For repulsive interactions, we find no in-medium
bound states. Second, we construct an effective model to describe these interactions,
and compare its predictions to the exact solution. We use this effective model
to study nonintegrable systems with unequal masses and/or potentials. We discuss
parameter regimes for which impurity-impurity attraction induced by the Fermi
gas can lead to the formation of in-medium bound states made of bosons that repel
each other in the absence of the Fermi gas.

text: Motivated by recent experimental observations of coherent many-body revivals
in a constrained Rydbergatom chain, we construct a weak quasilocal deformation
of the Rydberg-blockaded Hamiltonian, whichmakes the revivals virtually perfect.
Our analysis suggests the existence of an underlying nonintegrableHamiltonian
which supports an emergent SU(2)-spin dynamics within a small subspace of the
many-bodyHilbert space. We show that such perfect dynamics necessitates the existence
of atypical, nonergodicenergy eigenstates—quantum many-body scars. Furthermore,
using these insights, we construct a toymodel that hosts exact quantum many-body
scars, providing an intuitive explanation of their origin. Ourresults offer specific
routes to enhancing coherent many-body revivals and provide a step towardestablishing
the stability of quantum many-body scars in the thermodynamic limit.
