Lay Abstract Identify causal biological mechanisms of PTSD using a novel gene x environment mouse model of stress vulnerability, and characterize the interaction between PTSD-like symptoms and nicotine/alcohol consumption Identify SNPs associated with PTSD, or PTSD and comorbid substance use disorders, informed by our mouse model. Examine the genetics and epidemiology of substance abuse among m...

On irreversible investment

This paper develops a general theory of sequential irreversible investments in capital where a firm has the option to expand its current capacity or just wait for better time. Facing economic uncertainty, the firm has an operating function of the current capacity and an exogenous stochastic factor modelled by semimartingale. This general model encompasses all previously studied models, includin...

On Irreversible Deposition on Disordered Substrates

A number of processes in physics, chemistry and biology may be modelled by random sequential adsorption (RSA) on a lattice [1]. In this model, particles arrive randomly and adsorb irreversibly unless they are in the exclusion zone of previously adsorbed particles. In an arbitrary dimension, RSA processes reach a jamming configuration, where further adsorption events are impossible. The final co...

Physical nature of irreversible deformation of plant cells.

Etiolated mung bean hypocotyl segments were incubated in 0.25 m mannitol solutions with indoleacetic acid. They were then deformed mechanically with a longitudinal tensile force at a constant strain rate. The magnitudes of the mechanical forces were comparable to those of the hydrostatic forces existing in normally growing tissues. Each segment was repeatedly deformed and returned to zero force...
