OBJECTIVE Information about the psychiatric histories of adults with anxiety disorders was examined to further inform nosology and etiological/ preventive efforts. METHOD The authors used data from a prospective longitudinal study of a representative birth cohort (N=1,037) from ages 11 to 32 years, making psychiatric diagnoses according to DSM criteria. For adults with anxiety disorders at 32...

To examine risk and resilience factors that affect health, lifetime stress exposure histories, dispositional forgiveness levels, and mental and physical health were assessed in 148 young adults. Greater lifetime stress severity and lower levels of forgiveness each uniquely predicted worse mental and physical health. Analyses also revealed a graded Stress × Forgiveness interaction effect, wherei...

The concept of trade-offs is central to our understanding of life-history evolution. The underlying mechanisms, however, have been little studied. Oxidative stress results from a mismatch between the production of damaging reactive oxygen species (ROS) and the organism's capacity to mitigate their damaging effects. Managing oxidative stress is likely to be a major determinant of life histories,...

Quantum trajectory theory, developed largely in the quantum optics community to describe open quantum systems subjected to continuous monitoring, has applications in many areas of quantum physics. In this paper I present a simple model, using two-level quantum systems (q-bits), to illustrate the essential physics of quantum trajectories and how different monitoring schemes correspond to differe...

This paper focuses on the finite element based fatigue life prediction of lower suspension arm, subjected to variable amplitude loading. The objectives of this study are to predict fatigue life of the lower suspension arm using stress-life and strain-life methods, to investigate the effect of the mean stress. The lower suspension arm was developed using computer aided design software. The finit...

Methamphetamine was detected in a 77-year-old male who had a history of congestive heart failure. Using a modification of a previously reported method, trifluoroacetyl-l-prolyl chloride was used to derivatize sympathomimetic amines to allow separation and identification of individual enantiomers. The l-enantiomer of methamphetamine and a trace amount of l-amphetamine were found in blood and uri...
