A POLYNOMIAL ALGORITHM FOR ENUMERATING ALL VERTICES OF A BASE POLYHEDRON
Journal of the Operations Research Society of Japan, 1997 Summary: In general, it is difficult to enumerate all vertices of a polytope in polynomial time. Here we present a polynomial algorithm which enumerates all vertices of a submodular base polyhedron in \(O(n^3| V|)\) time and in \(O(n^2)\) space, where \(V\) is the vertex set of a base polyhedron and \(n\) the dimension of the underlying Euclidean space.

cis-β-Ru(II)heteroatom-stabilized-carbene complexes supported by tetradentate Schiff-base salen ligand [PDF]
, 2021 A panel of stable ruthenium carbene complexes bearing a tetradentate salen ligand, with their carbene-C atom adjacent to heteroatom, were synthesized from cis-β-Ru(II)-bis(CO) complex by reacting with the corresponding carbene precursors.

Model-predictive control in multi-contact based on stability polyhedrons [PDF]
2017 IEEE-RAS 17th International Conference on Humanoid Robotics (Humanoids), 2017 We propose a new linear model-predictive control scheme in multi-contact based on the center of mass reduced model. In order to linearize the dynamics of the CoM, we exploit the notion of stability polyhedrons associated to given contact stances, inside which the existence of contact forces is guaranteed. To compute stability polyhedrons, we have first

Discrete Wilson Lines in F-Theory
Advances in High Energy Physics, 2011 F-theory models are constructed where the 7 -brane has a nontrivial fundamental group. The base manifolds used are a toric Fano variety and a smooth toric threefold coming from a reflexive polyhedron.
