The well-known Galvin-Prikry Theorem states that Borel subsets of the Baire
space are Ramsey: Given any Borel subset X⊆[ω]ω, where [ω]ω is endowed with the metric
topology, each infinite subs...

The research on aerial manipulation systems has been increased rapidly in
recent years. These systems are very attractive for a wide range of
applications due to their unique features. However, dynamics, control and
manipulation tasks of su...

We propose a formal expansion of multiple relaxation times lattice Boltzmann
schemes in terms of a single infinitesimal numerical variable. The result is a
system of partial differential equations for the conserved moments of the
lattice Bo...
Simple subvector inference on sharp identified set in affine models

This paper studies a regularized support function estimator for bounds on
components of the parameter vector in the case in which the identified set is a
polygon. The proposed regularized estimator has three important properties: (i)
it has...
Estimating spillovers using imprecisely measured networks

In many experimental contexts, whether and how network interactions impact
the outcome of interest for both treated and untreated individuals are key
concerns. Networks data is often assumed to perfectly represent these possible
interaction...
Hierarchies for Relatively Hyperbolic Virtually Special Groups

Wise's Quasiconvex Hierarchy Theorem classifying hyperbolic virtually compact
special groups in terms of quasiconvex hierarchies played an essential role in
Agol's proof of the Virtual Haken Conjecture. Answering a question of Wise, we

High Energy Physics - Experiment
The correlations of identical charged kaons were measured in p-Pb collisions
at sNN=5.02 TeV by the ALICE experiment at the LHC. The
femtoscopic invariant radii and correlation strengths were extracted from
one-dimensional k...
A general mathematical framework for understanding the behavior of
heterogeneous stem cell regeneration

Stem cell heterogeneity is essential for the homeostasis in tissue
development. This paper established a general formulation for understanding the
dynamics of stem cell regeneration with cell heterogeneity and random
transitions of epigenet...

In this paper we establish necessary and sufficient conditions for the limit
set of a projective Anosov representation to be a differentiable submanifold of
projective space with Holder continuous derivatives. We also calculate the
optimal ...

This paper studies the measurement of advertising effects on online platforms
when parallel experimentation occurs, that is, when multiple advertisers
experiment concurrently. It provides a framework that makes precise how
