We study a method for proportional representation that was proposed at the
turn from the nineteenth to the twentieth century by Gustav Enestr\"om and
Edvard Phragm\'en. Like Phragm\'en's better-known iterative minimax method, it
is assumed ...

Since the original work on Bose-Einstein condensation, quantum degenerate
gases of atoms have allowed the quantum emulation of important systems from
condensed matter and nuclear physics, as well as the study of novel many-body
states with ...

We study the thermodynamics of a crystalline solid by applying intermediate
statistics obtained by deforming known solid state models using the mathematics
of q-analogs. We apply the resulting q-deformation to both the Einstein and
Deby...

The discrete orthogonality relations hold for all the orthogonal polynomials
obeying three term recurrence relations. We show that they also hold for
multi-indexed Laguerre and Jacobi polynomials, which are new orthogonal
polynomials obtain...

We construct self-gravitating razor-thin disks of counterrotating dust around
Schwarzschild black holes (BHs) by applying the "displace, cut, and reflect"
method to known seed solutions representing multi-holes. All but one of the
sources o...

In this paper, we present a neural network-enabled data distribution aware
sorting method, coined as NN-sort. Our approach explores the potential of
developing deep learning techniques to speed up large-scale sort operations,
enabling data ...
Moduli Spaces of Pentagonal Subdivision Tilings

Pentagonal subdivision gives three families of edge-to-edge tilings of the
sphere by congruent pentagons. Each family forms a two dimensional moduli. We
describe the moduli in detail....

We propose a non-volatile memory element based on a lateral ferromagnetic
Josephson junction with spin-orbit coupling and out-of-plane magnetization. The
interplay between the latter and the intrinsic exchange field of the
ferromagnet leads...

We study a supply chain ordering problem faced by a wholesale supplier
serving unpredictable demand. In this problem, the supplier has an initial
stock, and faces a stream of orders for different amounts that are unknown a
priori. Each orde...

This paper presents the scenario that gravitational waves, generated in
core-collapse of a pre-supernova star, can produce both electromagnetic
radiation and sound radiation as gravitational waves propagate outward from the
collapsing core....
