Bioimpedance measurements are useful for determining a variety of biological conditions. By accounting for small impedance variations due to the arterial pulse, the effect of the blood can be studied more closely. The quasi-circulator system presented enables monitoring of pulsatile impedance changes with input frequencies above 1 MHz. The adjustable Rmatch allows for dynamic tuning of the system to increase sensitivity. By tuning Rmatch to be near the match point, the pulsatile signal in the output magnitude can be amplified, and tuning Rmatch to be at the match point causes the pulsatile signal in the output phase to be amplified. The system is tested on discrete circuit elements as well as human subjects, and results are analyzed. Pulsatile variations in the output voltage signal of up to 7 mV and 2.3° are demonstrated on human subjects. Tuning Rmatch allows for the pulsatile signal to be increased by more than 4 times.

Traditionally, juvenile sex offenders have been ignored in the literature. More recently the research has expanded particularly in the area of assessment and treatment. This study focused on the assessment of sexual arousal to deviant stimuli using the penile plethysmography (PPG) since it likely plays a significant role in juvenile sex offending behaviors. The goal of this study assessed its validity and reliability using Becker et al.'s set of PPG scenarios with a population of juvenile sex offenders. Significant differences were found between groups of (a) admitters versus partial admitters and (b) offenders with and without male victims. This study also examined the latent structure of the PPG results and found three dimensions: arousal to male stimuli, arousal to females and paraphilias, and arousal to non-sexual acts. These findings provide important implications for assessment of juvenile sex offenders and add to the clinical utility of PPG assessments.
