High Energy Physics - Phenomenology
The CMS collaboration has recently reported the results of a low-mass
Higgs-boson search in the di-photon final state based on the full Run 2 data
set with refined analysis techniques. The new results show an excess of events
at a mass of a...
Notions of enriched purity

Mathematics
Category Theory
We introduce the enriched notions of purity depending on the left class
E of a factorization system on the base V of enrichment.
The ordinary purity is given by the class of surjective mappings in the
category of sets....

We provide theoretical convergence bounds for the variational Monte Carlo
(VMC) method as applied to optimize neural network wave functions for the
electronic structure problem. We study both the energy minimization phase and
the supervised...
Semiparametric logistic regression for inference on relative vaccine

Methodology
We develop semiparametric methods for estimating subgroup-specific relative
vaccine efficacy against multiple viral strains in a partially vaccinated
population. Focusing on observational case-only studies, we address informative

The problem of deriving a gradient flow structure for the porous medium
equation which is {\em thermodynamic}, in that it arises from the large
deviations of some microscopic particle system, is studied. To this end, a
rescaled zero-range p...

We show that for any permutation ω, the increasing flip graph on
acyclic pipe dreams with exiting permutation ω is a lattice quotient of
the interval [e,ω] of the weak order. We then discuss conjectural
generalizations ...

The goal of data-free meta-learning is to learn useful prior knowledge from a
collection of pre-trained models without accessing their training data.
However, existing works only solve the problem in parameter space, which (i)
ignore the fr...
