Research on the progression from substance use to dependence typically relies on lifetime retrospective reports of dependence among ever users. We sought to evaluate probability and correlates of dependence among recent (past-year) weekly users of alcohol, nicotine, cannabis, and cocaine through cross-sectional and prospective analyses.Data on ...

A regularity condition on the transition probability measure of a diffusion process
Stochastics, 1985Let ox and a2 be given constants with 0rij2, and let {{t):0StST} be a one-dimensional diffusion process which has zerodrift and whose diffusion coefficient o satisfies 0002 everywhere. This paper establishes a regularity condition on the distribution of (T) for such a process. Let A U and let \A\ denote the diameter of A.

The relation between the discard and regularity conditions for choice probabilities
Journal of Mathematical Psychology, 1965Abstract A set of choice probabilities satisfies the regularity condition if the probability of choosing and alternative from any set is at least as great as the probability of choosing it from any of its supersets. It satisfies strict regularity if the probability of choice from each set is strictly greater than the probability of choice from each ...

Primitive conditional probabilities, subset relations and comparative regularity
AnalysisAbstract Rational agents seem more confident in any possible event than in an impossible event. But if rational credences are real-valued, then there are some possible events that are assigned 0 credence nonetheless. How do we differentiate these events from impossible events when we order events?

2019 IEEE International Conference on Advanced Trends in Information Theory (ATIT), 2019
Typically destructive actions and harmful effects on the complex system are random. However, for the evaluation of random events of such type, the use of probability theory is difficult, since such actions do not have the mass nature required for estimating the frequency of events.

A Free-Probability Spectral Criterion for Conditional Regularity of 3D Navier-Stokes Equations
I present the first explicit, computationally verifiable spectral criterion for regularity of three-dimensional Navier-Stokes equations, one of the Clay Institute's Millennium Prize Problems. By introducing free probability theory to fluid dynamics, we derive concrete conditions under which turbulent flows provably remain smooth.openaire +1 more source
Free probability bounds and a spectral criterion for conditional regularity of 3-D Navier-Stokes
I am introducing a rigorously proven conditional regularity theorem for the three-dimensional Navier–Stokes equations. Using non-commutative (free-probability) inequalities, they show that if cross-scale velocity correlations stay below a concrete threshold—easily monitored in modern CFD codes—then the fluid remains smooth for all time.openaire +1 more source
