Improvement in survivorship: The key for population recovery? [PDF]
, 2016 In northern Patagonia, commercial harvesting of South American sea lions, Otaria flavescens, from 1920 to 1960, decimated its population abundance. Population recovery was not immediate after hunting ceased in 1962.

A Generic Sample Splitting Approach for Refined Community Recovery in Stochastic Block Models [PDF]
, 2014 We propose and analyze a generic method for community recovery in stochastic block models and degree corrected block models. This approach can exactly recover the hidden communities with high probability when the expected node degrees are of order $\log ...
