Magnetic Resonance in Medicine, EarlyView.Abstract Purpose To enable contactless cardiac gating at 0.55T using pilot tone (PT). Current PT methods are unable to extract weak motions, including cardiac motion, at lower B0 field strengths (<1.5T). Methods We utilize high‐amplitude pilot tone with interference cancellation, termed HAPTIC.

Evaluation of a new air displacement plethysmograph for measuring human body composition.
Medicine & Science in Sports & Exercise, 1995 A new air displacement plethysmograph, the BOD POD (BP), was evaluated in comparison to hydrostatic weighing (HW). Sixty-eight adult subjects (26 F, 42 M) varying widely in age (range 20-56 yr), ethnicity, and fatness participated in this study. Same-day

Epilepsia, EarlyView.Abstract Objective Patients with uncontrolled epilepsy are at high risk for sudden unexpected death in epilepsy (SUDEP), which likely results from a pathological, seizure‐induced disruption of vital physiological systems. The objective of this study was to characterize seizure‐induced physiological dysfunction leading to death in SSKcnj16−/− rats and ...

Supervised Release, Sex-Offender Treatment Programs, and Substantive Due Process [PDF]
, 2016 This Note argues that mandated PPG testing should be eliminated as a condition of federal supervised release. The test infringes on a constitutionally protected liberty interest against unwanted bodily intrusions and, as only the Second Circuit has held,

Longitudinal Changes in Aerodigestive Responses to Varying Nipple Properties in Infant Pigs
Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 343, Issue 5, Page 608-616, June 2025.ABSTRACT Coordination of respiration and swallowing is critical for survival in infant mammals and changes throughout infant maturation. Infants show sensorimotor feeding responses to changes in physical properties of nipples. Commercial nipples are promoted as improving aerodigestive coordination. However, it is unknown how nipple properties influence
