Bad semidefinite programs: they all look the same [PDF]
, 2017 Conic linear programs, among them semidefinite programs, often behave pathologically: the optimal values of the primal and dual programs may differ, and may not be attained. We present a novel analysis of these pathological behaviors.

Exact duality in semidefinite programming based on elementary reformulations [PDF]
, 2015 In semidefinite programming (SDP), unlike in linear programming, Farkas' lemma may fail to prove infeasibility. Here we obtain an exact, short certificate of infeasibility in SDP by an elementary approach: we reformulate any semidefinite system of the ...

Polyhedral approximation in mixed-integer convex optimization
, 2017 Generalizing both mixed-integer linear optimization and convex optimization, mixed-integer convex optimization possesses broad modeling power but has seen relatively few advances in general-purpose solvers in recent years.

Rejuvenated Amorphous Alloys: Processing Methods, Microstructures and Mechanical Properties
Advanced Science, EarlyView.Three rejuvenation methods – mechanical and thermal rejuvenation, and other rejuvenation routes such as ultrasonic processing – can be used to modify structures of glassy alloys, especially atomic clusters, and therefore enhances plasticity and activates work‐hardening behaviors.
