A modification of Young's total perineal prostatectomy technique is described to prevent damage to the apical branches of the cavernous nerves. Based on anatomic relationships between investing prostatic fascial layers and the neurovascular bundle, emphasis is placed on division of the apical prostatic urethra between the anterolateral endopelvic fascia and(More)
In this paper we present a novel architecture for phase-locked loop (PLL) based high-speed demodulation of frequency-modulated (FM) atomic force microscopy (AFM) signals. In our approach, we use single-sideband (SSB) frequency upconversion to translate the AFM signal from the position sensitive detector to a fixed intermediate frequency (IF) of 10 MHz. In(More)
In this paper we present a novel system architecture for high-speed FM-AFM electronics. The proposed system consists of a PLL-based FM demodulator preceded by a SSB modulator and driving electronics ensuring a stable self-oscillation of the cantilever. Thanks to the SSB upconverion preceding the FM-demodulator, the system allows for demodulation bandwidths(More)
To determine the incidence of penile condyloma in a group of high risk males, we have performed magnified penile surface scanning and biopsy of suspicious lesions in 51 men. All men were partners of women with proven condyloma. Of these men, 45 were found to have histologic evidence of condyloma, only 8 of which were grossly visible.

In this way, we fully benefit from the excellent noise performance(More)
