Bubble nucleation in a cold spin 1 gas
New Journal of Physics, 2023 Cold atomic gases offer the prospect of simulating the physics of the very early Universe in the laboratory. In the condensate phase, the gas is described by a field theory with key features of high energy particle theory.

Almost Periodic Solutions for Impulsive Fractional Stochastic Evolution Equations
International Journal of Analysis and Applications, 2014 In this paper, we consider the existence of square-mean piecewise almost periodic solutions for impulsive fractional stochastic evolution equations involving Caputo fractional derivative.

Journal of Business & Economic Statistics, 2018 This study develops and implements methods for analyzing whether introducing new securities or relaxing investment constraints improves the investment opportunity set for risk averse investors. We develop a statistical test procedure for ‘stochastic spanning’ for two nested polyhedral portfolio sets based on subsampling and Linear Programming. The test

A hybrid method for optimizing a complex system reliability [PDF]
International Journal for Simulation and Multidisciplinary Design Optimization, 2010 In this paper we present a new hybrid method for maximizing a complex system reliability. The hybridization of two methods, namely the Penalty Simultaneous Perturbation Stochastic Approximation (PSPSA) and the heuristic method Sharma-Venkateswaran ...

Proceedings of the National Academy of Sciences, 2015 In 1953, Lloyd Shapley contributed his paper “Stochastic games” to PNAS. In this paper, he defined the model of stochastic games, which were the first general dynamic model of a game to be defined, and proved that it admits a stationary equilibrium. In this Perspective, we summarize the historical context and the impact of Shapley’s contribution.
