The battle of Kursk between Soviet and German is known to be the biggest tank
battle in the history. The present paper uses the tank and artillery data from
the Kursk database for fitting both forms of homogeneous and heterogeneous

We present a novel framework for estimation and inference for the broad class
of universal approximators. Estimation is based on the decomposition of model
predictions into Shapley values. Inference relies on analyzing the bias and
variance...

In this paper, we aim to develop a hybridizable discontinuous Galerkin (HDG)
method for the indefinite time-harmonic Maxwell equations with the perfectly
conducting boundary in the three-dimensional space. First, we derive the
wavenumber ex...

Let S be a certain affine algebraic surface over Q such that it
admits a regular map to A2/Q. We show that any non-trivial

History and Overview
A polyhedral product is a natural subspace of a Cartesian product that is
specified by a simplicial complex. The modern formalism arose as a
generalization of the spaces known as moment-angle complexes which were
developed within the nascen...

We consider an atomic congestion game in which each player i participates
in the game with an exogenous and known probability pi∈(0,1],
independently of everybody else, or stays out and incurs no cost. We compute

For time projection chambers (TPCs) the accuracy in measurement of track
coordinates along the pad row direction deteriorates with the drift distance

Persistent Betti numbers are a major tool in persistent homology, a subfield

It was conjectured by Gupta et al. [Combinatorica04] that every planar graph
can be embedded into ℓ1 with constant distortion. However, given an
n-vertex weighted planar graph, the best upper bound on the distortion is
only $O(\sqrt...
