The most widely used technique for finding the largest or smallest values of a math function turns out to be a fundamentally difficult computational problem. Many aspects of modern applied research ...

We consider the class of continuous functions that map an open set Ω ⊆ ℝn to ℝ with an epigraph having (locally) positive reach with an additional property. This class contains all finite convex and ...

Wnt proteins function as morphogens that can form long-range concentration gradients to pattern developing tissues. Here, we show that the retromer, a multiprotein complex involved in intracellular ...

After growing heart tissue on a chip, researchers have explored how it responds to a simulated heart attack. Heart disease is one of the leading causes of death globally. Those who survive a heart ...
