The celestial chiral algebra of self-dual gravity on Eguchi-Hanson space [PDF]
We consider the twistor description of classical self-dual Einstein gravity in the presence of a defect operator wrapping a certain ℂℙ1. The backreaction of this defect deforms the flat twistor space to that of Eguchi-Hanson space.

A new construction of compact torsion-free $G_2$-manifolds by gluing families of Eguchi-Hanson spaces [PDF]
We give a new construction of compact Riemannian 7-manifolds with holonomy $G_2$. Let $M$ be a torsion-free $G_2$-manifold (which can have holonomy a proper subgroup of $G_2$) such that $M$ admits an involution $\iota$ preserving the $G_2$-structure ...

The Blum-Hanson Property [PDF]
Given a (real or complex, separable) Banach space, and a contraction T on X, we say that T has the Blum-Hanson property if whenever x, y ∈ X are such that Tnx tends weakly to y in X as n tends to infinity, the ...

A note on the Hanson-Wright inequality for random vectors with dependencies [PDF]
We prove that quadratic forms in isotropic random vectors $X$ in $\mathbb{R}^n$, possessing the convex concentration property with constant $K$, satisfy the Hanson-Wright inequality with constant $CK$, where $C$ is an absolute constant, thus eliminating ...

The Lawson‐Hanson algorithm with deviation maximization: Finite convergence and sparse recovery [PDF]
The Lawson‐Hanson with Deviation Maximization (LHDM) method is a block algorithm for the solution of NonNegative Least Squares (NNLS) problems. In this work we devise an improved version of LHDM and we show that it terminates in a finite number of steps,

Description of a Neotropical gall inducer on Araceae: Arastichus, gen. nov. (Hymenoptera, Eulophidae) and two new species [PDF]
A new genus of a Neotropical gall inducing tetrastichine eulophid on Araceae is described and confirmed using Ultraconserved Elements (UCE) phylogenomic data. Arastichus Gates, Hanson, Jansen-González & Zhang, gen.

Decoding Physical and Cognitive Impacts of Particulate Matter Concentrations at Ultra-Fine Scales
The human body is an incredible and complex sensing system. Environmental factors trigger a wide range of automatic neurophysiological responses. Biometric sensors can capture these responses in real time, providing clues about the underlying biophysical

The self-dual classical double copy, and the Eguchi-Hanson instanton [PDF]
A bstractThe double copy is a map from non-abelian gauge theories to gravity, that has been demonstrated both for scattering amplitudes and exact classical solutions.
