Distributions of neuronal activity within cortical circuits are often found
to display highly skewed shapes with many neurons emitting action potentials at
low or vanishing rates, while some are active at high rates. Theoretical

We investigate the effect of repulsive interaction between hadrons on the
susceptibilities of conserved charges, namely baryon number (B), electric
charge (Q) and strangeness (S). We estimate second fourth and sixth-order
susceptibilities o...

In this note we state a conjecture that characterizes unital C*-algebras for
which the unitary group is amenable as a topological group in the norm
topology. We prove the conjecture for simple, separable, stably finite, unital,

We introduce the first random matrix model of a complex β-ensemble. The
matrices are tridiagonal and can be thought of as the non-Hermitian analogue of
the Hermite β-ensembles discovered by Dumitriu and Edelman (J. Math.

Even though neural networks have been long deployed in applications involving
tabular data, still existing neural architectures are not explainable by

Learning with reduced labeling standards, such as noisy label, partial label,
and multiple label candidates, which we generically refer to as
\textit{imprecise} labels, is a commonplace challenge in machine learning
tasks. Previous methods ...

We address the key question of representation of chiral topological quantum
states in (2+1) dimensions (i.e., with non-zero chiral central charge) by
Projected Entangled Pair States (PEPS). A noted result (due to Wahl, Tu,
Schuch, and Cirac...
