The number of maximal matchings in polygon rings
A matching of graph $G$ is maximal if it cannot be expanded by adding any edge to create a larger matching. In this paper, for a hexagonal ring $H$ with $n$ hexagons, we show that the number of maximal matchings of $H$ equals to the trace of the product of $n$ matrices, each of which is $S$, $L$, or $R$ according to the type of the connection mode of $H$. Finally, we extend this conclusion to arbitrary polygon rings and provide an algorithm to determine the transition matrices of polygon chains…

Constraining Ongoing Volcanic Outgassing Rates and Interior Compositions of Extrasolar Planets with Mass Measurements of Plasma Tori
We present a novel method of constraining volcanic activity on extrasolar terrestrial worlds via characterization of circumstellar plasma tori. Our work generalizes the physics of the Io plasma torus to propose a hypothetical circumstellar plasma torus generated by exoplanetary volcanism. The quasi-steady torus mass is determined by a balance between material injection and ejection rates from volcanic activity and corotating magnetospheric convection, respectively. By estimating the Alfvén sur…

Thermal Radiation Exchange between Nanoparticles Heated by Arc Discharge
The heating of particles by plasma radiation plays a critical role in space science involving dusty plasma as well as in industrial processes such as plasma vapor deposition, microchip production, etching and plasma fusion. Numerical modeling of radiation heat transfer from plasma to nano-scale particles includes exchange of scattered thermal radiation between particles-an effect that was neglected in prior studies in which temperature of particles was estimated. Thermal modeling of gas loaded …

A unified fluid model for nonthermal plasmas and reacting flows
This work presents a unified fluid modeling framework for reacting flows coupled with nonthermal plasmas (NTPs). Building upon the gas-plasma kinetics solver, ChemPlasKin, and the CFD library, OpenFOAM, the integrated solver, reactPlasFOAM, allows simulation of fully coupled plasma-combustion systems with versatility and high performance. By simplifying the governing equations according to the dominant physical phenomena at each stage, the solver seamlessly switches between four operating modes…

Morse theory and moduli spaces of self-avoiding polygonal linkages
We show that a smooth manifold is diffeomorphic to a Euclidean space if it admits a Lyapunov-Reeb function. Here a Lyapunov-Reeb function means a smooth function that is proper, bounded from below and possesses only one critical point. As applications, we determine the topology of moduli spaces of self-avoiding polygonal linkages by constructing Lyapunov-Reeb functions, and we prove a conjecture of González and Sedano-Mendoza on moduli spaces of simple polygons. We further describe foliation s…
