Self-loops in evolutionary graph theory: Friends or foes?
PLOS Computational Biology, 2023 Evolutionary dynamics in spatially structured populations has been studied for a long time. More recently, the focus has been to construct structures that amplify selection by fixing beneficial mutations with higher probability than the well-mixed population and lower probability of fixation for deleterious mutations.

The H-graph with equal masses in terms of multiple polylogarithms
Physics Letters B, 2021 The initial phase of the inspiral process of a binary system producing gravitational waves can be described by perturbation theory. At the third post-Minkowskian order a two-loop double box graph, known as H-graph contributes.

Generating loop graphs via Hopf algebra in quantum field theory [PDF]
Journal of Mathematical Physics, 2006 We use the Hopf algebra structure of the time-ordered algebra of field operators to generate all connected weighted Feynman graphs in a recursive and efficient manner. The algebraic representation of the graphs is such that they can be evaluated directly as contributions to the connected n-point functions.
