Possible Effects of the Fractal Distribution of Relic Wormholes
Universe, 2021 We discuss the possibility that the distribution of relic wormholes may possess fractal properties. Relic wormholes and their fractal distributions are predicted in a natural way by lattice quantum gravity models.

Perturbations of Superintegrable Systems [PDF]
, 2015 A superintegrable system has more integrals of motion than degrees d of freedom. The quasi-periodic motions then spin around tori of dimension n < d. Already under integrable perturbations almost all n-tori will break up; in the non-degenerate case the ...

Mathematical modeling of tumor-immune cell interactions.
Journal of Theoretical Biology, 2019 The anti-tumor activity of the immune system is increasingly recognized as critical for the mounting of a prolonged and effective response to cancer growth and invasion, and for preventing recurrence following resection or treatment.

Mathematical model of sarcoidosis [PDF]
Proceedings of the National Academy of Sciences, 2014 SignificanceSarcoidosis is a disease involving abnormal collection of granulomas that develop in the lung and other organs. The origin of the disease is unknown, clinical data are very limited, and there is no current effective treatment. This paper develops a mathematical model with simulations that are validated by the available clinical data.

The acquaintance time of (percolated) random geometric graphs [PDF]
, 2015 In this paper, we study the acquaintance time AC(G) defined for a connected graph G. We focus on G(n,r,p), a random subgraph of a random geometric graph in which n vertices are chosen uniformly at random and independently from [0,1]2, and two vertices ...

Vertical Transmission in a Two-Strain Model of Dengue Fever
Letters in Biomathematics, 2014 The role of vertical transmission in vectors has rarely been addressed in the study of dengue dynamics and control, in part because it was not considered a critical population-level factor.
