Exocomets: Now you see them, now you don'tMinor bodies such as Kuiper Belt objects, comets, and asteroids constitute the rocky and icy debris left over from the planet building phase of our solar system. The existence of reservoirs of small rocky bodies (i.e., asteroids/planetesimals) in orbits around young stellar systems is now well established, with their presence ...

Addressing methane emissions: technology limits to mitigation policyMethane, a short-lived and potent greenhouse gas, presents a unique challenge: unlike carbon dioxide, it is emitted from a large number of highly distributed sources. In this regard, timely and cost-effective leak detection across large-scale facilities becomes a priority. As part of a federal push to reduce methane emissions from ...

Do Brains Compute, and How Can We Tell?Brains are paradigmatically information-processing systems, and this is often taken to mean that brains perform computation, and furthermore, that we can both explain and reproduce the brain's capabilities by elucidating the computations involved. But is there really some distinctive activity "computing" that all and only brains and computers perform? Are ...

Stochastic Hybrid Approximation Algorithms and Applications to Power Generation DispatchIn many important applications, including power system operations planning, optimization problems arise where decisions need to be made in the presence of uncertainty. Solving these problems is in general a challenging task due to the computational complexity of evaluating the functions that account for the uncertainty. Typical approaches for solving ...
