Finite Subdivision Rules from Matings of Quadratic Functions: Existence and Constructions
… as tools to model the dynamic behavior of mated quadratic functions. Several methods of construction of invariant structures on modified degenerate matings are detailed, and examples of parameter-based families of matings for which these methods succeed (and fail) are given.

Greed, hedging, and acceleration in convex optimization
… second main message is a universality result for quadratic optimization. We show that, roughly speaking, "most" Krylov-subspace algorithms are asymptotically optimal (in the worst-case) and "most" quadratic functions are asymptotically worst-case functions (for all algorithms). From an algorithmic …

An Aerodynamic Model for Use in the High Angle of Attack Regime
… derivative approach, are not constant but rather quadratic functions of the new state variable. Finally, the concept of the model was expanded to allow for the addition of longitudinal motions. Thus, pitching moments will be identified at the same time as rolling moments. The results show that the …
