We demonstrate a novel algorithm for removing adverse effects of motion in distributed strain measurements via Optical Frequency Domain Reflectometry (OFDR), using Rayleigh backscatter from low-bend loss fiber as the transducer. Vibration amplitudes

The impact of “moral injury” (MI) among deployed veterans, defined as actions in combat that violate a veteran's moral beliefs and result in psychological distress, has increasingly become a significant clinical concern separate from other trauma

This study explored attitudes toward hypothetical genetic testing for posttraumatic stress disorder (PTSD) and addiction among veterans. We surveyed a random sample of community-based veterans (n = 700) by telephone. One year later, we asked the vete
