Estimating Heterogeneous and Hierarchical Peer Effects on Body Weight Using Roommate Assignments as a Natural Experiment
Heterogeneous Hierarchical Peer Body Weight Roommate Assignments Natural Experiment
2016/3/3
We investigate peer effects in weight gain by exploiting a natural experiment, roommate assignments of 751 male and 845 female first-year college students. Results indicate that females are subject to...
Wave patterns generated by a supersonic moving body in a binary Bose-Einstein condensate
Generation of wave structure two-dimensional bose-einstein condensate sound mixing speed coupling
2014/12/24
Generation of wave structures by a two-dimensional (2D) object (laser beam) moving in a 2D two-component Bose-Einstein condensate with a velocity greater than the two sound velocities of the mixture i...
Motion of a Rigid Body under Random Perturbation
rigid body stochastic dierential equation rotation group compact Lie group
2009/4/27
We use stochastic analysis to study the random motion of a rigid body under a white noise perturbation. We obtain a formula for the angular velocity in an average sense and discuss the stability near ...
