We report a brittle Mg-based bulk metallic glass which approaches the ideal brittle behavior. However, a dimple structure is observed at the fracture surface by high resolution scanning electron microscopy, indicating some type of "ductile" fracture mechanism in this very brittle glass. We also show, from the available data, a clear correlation between the fracture toughness and plastic process...

Incompatible goals among multiple agents working on domains involving finite constraints can be a source of conflict. This conflict, in the form of incompatible constraints established locally by the agents and imposed on the negotiated variables, may break the dialogue between these agents even though they could, in principle, reach an agreement. A common means of coordinating multi-agent syst...

The incorporation of priors [30] in the Optimal Uncertainty Quantification (OUQ) framework [31] reveals brittleness in Bayesian inference; a model may share an arbitrarily large number of finite-dimensional marginals with, or be arbitrarily close (in Prokhorov or total variation metrics) to, the data-generating distribution and still make the largest possible prediction error after conditioning...
