Clinical Psychology Review, 2010 Optimism is an individual difference variable that reflects the extent to which people hold generalized favorable expectancies for their future. Higher levels of optimism have been related prospectively to better subjective well-being in times of adversity or difficulty (i.e., controlling for previous well-being).

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

Optimising the laser-welded butt-joints of medium carbon steel using RSM [PDF]
, 2005 The optimization capabilities in design-expert software were used to optimise the keyhole parameters (i.e. maximize penetration (P) and minimise the heat input, width of welded zone, (W) and width of heat affected zone (WHAZ)) in CW CO2 laser butt ...

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

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.

Two-stage hybrid algorithm for recognition of industrial slab numbers with data quality improvement
Complex & Intelligent Systems, 2022 As the unique recognition of each slab, the accurate recognition of slab number is especially critical for the hot rolling production process. However, the collected data are often of low quality due to poor production environment conditions, making ...
