BACKGROUND There are concerns regarding the validity of combat exposure reports of veterans seeking treatment for combat-related post-traumatic stress disorder (PTSD) within US Veterans Affairs Medical Centers. AIMS To verify combat exposure history for a relevant sample through objective historical data. METHOD Archival records were reviewed from the US National Military Personnel Records ...

Migraine headache is a growing problem for U.S. servicemembers deployed to Iraq and Afghanistan and has been linked to substantial negative socioeconomic consequences. However, there has been no comprehensive examination of the relationship between combat exposure and migraine headache or its stress-related triggers. Analyzing data drawn from the National Longitudinal Study of Adolescent Health...

The combat veteran paradox proposes that most changes individuals experience resulting from combat exposure are normal, and not indicative of a mental health disorder. Yet, because of the number and complexities of these changes, the combat veteran paradox states that combat veterans who are healthy can benefit from counseling. Counseling should focus on helping the combat veteran understand ho...

Until relatively recently cluster studies have been confined to the region encompassing the line of beta stability. As clustering is expected to manifest itself most strongly near thresholds, exotic structures might be expected to form in the more weakly bound systems found in the vicinity of the driplines. Perhaps the most striking example of this are the halo nuclei. In the present paper two ...

This paper reviews the available information on the central density distribution and shape of the Milky Way’s halo. At present, there is no strong evidence that the Milky Way’s halo properties conflict with the predictions of cold dark matter (CDM): a primordial central power law cusp can be accommodated by the observations, and the current constraints on flattening are also consistent with the...

An ac dipole with horizontally oriented oscillating magnetic field (spin flipper) was installed in RHIC to reverse the spin direction in the presence of two full Siberian snakes, thereby reducing the systematic errors for the spin physics experiments in RHIC. With two full snakes, the spin vector completes one full precession around the vertical direction in two revolutions, and the spin depola...
