In this report, we use the complex-step derivative approximation technique to compute sensitivities for delay differential equations (DDEs) with non-smooth (discontinuous and even distributional) ...

Separating different versions of elements—isotopes—is an excruciatingly difficult task: They differ by just one or two extra neutrons, an infinitesimal difference in mass. But University of Chicago ...
