Emerging Topics in Life Sciences, 2023 The young field of gastruloids brings promise to modeling and understanding early embryonic development. However, being a complex model, gastruloids are prone to variability at different levels. In this perspective, we define the different levels of gastruloid variability, and parameters over which it can be measured.

Asymptotic optimality in stochastic optimization [PDF]
The Annals of Statistics, 2021 We study local complexity measures for stochastic convex optimization problems, providing a local minimax theory analogous to that of Hájek and Le Cam for classical statistical problems. We give complementary optimality results, developing fully online methods that adaptively achieve optimal convergence guarantees. Our results provide function-specific

In addition, they show overoptimism toward people or social groups they identify with compared with those they do not identify with (social

PLoS ONE, 2008 Semelparous organisms have a simple life cycle characterized by immediate death after reproduction. We assume that semelparous life histories can be separated into a juvenile non-reproductive period followed by an adult period during which reproduction is possible. We derive formulae for the optimal age and size at reproduction and for the optimal size

A Cross-Country Study of Comparative Optimism About Privacy Risks on Social Media
International Journal of Communication, 2023 People exhibit comparative optimism about privacy risks, believing that they are personally less vulnerable to privacy threats than their average peers, and yet comparative optimism about privacy threats can lead to reckless online behaviors.

Econometrica, 1985 This paper presents a general model of search in which the searcher maximizes the expected utility of search by choosing not only the number of periods of search but also the size of sample to be taken each period. Both no-recall and full-recall cases are allowed and the cost of search includes not only financial but also psychic cost.

Current Biology, 2022 Before visiting your local supermarket, do you write your food shopping list in the order you expect to encounter the items as you walk around, aisle by aisle? This way, you minimise your travel distance, saving time and effort. Many other animals do the same.
