The Estrada index of a graph/network is defined as the trace of the adjacency matrix
exponential. It has been extended to other graph-theoretic matrices, such as the Laplacian …

We introduce a compartment model with memory for the dynamics of epidemic spreading in
a constant population of individuals. Each individual is in one of the states S= susceptible, I …

This study investigated the allosteric action within the receptor-binding domain (RBD) of the
SARS-CoV-2 spike protein caused by class 3 monoclonal antibody (mAb) binding. As the …

When analyzing complex networks, an important task is the identification of those nodes
which play a leading role for the overall communicability of the network. In the context of …

The modified Bessel function (MBF) of the first kind is a fundamental special function in
mathematics with applications in a large number of areas. When the order of this function is …

We propose a novel stochastic algorithm that randomly samples entire rows and columns of
the matrix as a way to approximate an arbitrary matrix function using the power series …

Structural balance is an important characteristic of graphs/networks where edges can be
positive or negative, with direct impact on the study of real-world complex systems. When a …

Complex networks are made up of vertices and edges. The latter connect the vertices. There
are several ways to measure the importance of the vertices, eg, by counting the number of …

We present a stochastic method for efficiently computing the solution of time-fractional partial
differential equations (fPDEs) that model anomalous diffusion problems of the subdiffusive …
