Triploid oysters are widely used in off-bottom aquaculture of eastern oysters, Crassostrea virginica. However, farmers the Gulf Mexico (GoM) and Atlantic coast estuaries have observed unresolved, late-spring die-offs triploid threatening sustainability aquaculture. To investigate this, physiological processes underlying oyster growth (e.g., feeding, respiration) mortality one-year-old diploid w...

We analyze general model selection procedures using penalized empirical loss minimization under computational constraints. While classical model selection approaches do not consider computational aspects of performing model selection, we argue that any practical model selection procedure must not only trade off estimation and approximation error, but also the computational effort required to co...

The Off-plane Grating Rocket Experiment (OGRE) is a soft x-ray grating spectrometer to be flown on suborbital rocket. payload designed obtain the highest-resolution spectrum of Capella date with resolution goal R ( λ / Δλ ) > 2000 at select wavelengths in its 10 55 Å bandpass interest. optical design realizes theoretical maximum ≈ 5000, but this performance does not consider finite individual c...

We study the problem of maximizing the amount of stochastic diffusion in a network by acquiring nodes within a certain limited budget. We use a Sample Average Approximation (SAA) scheme to translate this stochastic problem into a simulation-based deterministic optimization problem, and present a detailed empirical study of three variants of the problem: where all purchases are made upfront, whe...

We study fiscal spending by supranational unions, where participation is voluntary and countries bargain over contributions to and the allocation of a central budget. We establish and explore the link between the budget’s allocation and nations’ contributions that occurs since bargaining power is endogenous, and a country’s outside option during budget negotiations is to withdraw its contributi...

introduction: coronary artery disease (cad) is the most common type of heart disease, with a mortality rate of 385,000 person per year in the united states. there are two main methods for cad treatments: angioplasty and bypass surgery. coronary artery bypass grafting (cabg) is one of the greatest surgical operations of the 20th century and it is presented as most effective and long-term therapi...
