Studies of neutron stars are extremely timely given the recent detection of
gravitational waves from a binary neutron star merger GW170817, and an
International Space Station payload NICER currently in operation that aims to
determine radii...

We present an accurate, robust and fast method for registration of 3D scans.
Our motion estimation optimizes a robust cost function on the intrinsic
representation of rigid motions, i.e., the Special Euclidean group
SE(3). We exp...

This paper gives a new perspective on the theory of principal Galois orders,
as developed by Futorny, Ovsienko, Hartwig, and others. Every principal Galois
order can be written as eFe for any idempotent e in an algebra F, which
we cal...
A Fast and Efficient algorithm for Many-To-Many Matching of Points with
Demands in One Dimension

Given two point sets S and T, the minimum-cost many-to-many matching with
demands (MMD) problem is the problem of finding a minimum-cost many-to-many
matching between S and T such that each point of S (respectively T) is matched
to at least...
Meta-analysis of Bayesian analyses

Meta-analysis aims to generalize results from multiple related statistical
analyses through a combined analysis. While the natural outcome of a Bayesian
study is a posterior distribution, traditional Bayesian meta-analyses proceed
by combin...

Rings and Algebras
Given a subdirectly irreducible *-regular ring R, we show that R is a
homomorphic image of a regular *-subring of an ultraproduct of the (simple)
eRe, e in the minimal ideal of R; moreover, R (with unit) is directly finite if
all eRe are un...

This paper suggests a statistical framework for describing the relations
between the physical and conceptual entities of a brain-like model. Features
and concept instances are put into context, where the paper suggests that
features may be ...

In the present paper we study a type of generic singularity of mean curvature

derive an asymptotic profile for a neighborhood of singularity....
