Summary: The aim of this study was to compare the infection risk between the AUA-recommended prophylaxis (vancomycin and gentamicin alone) and nonstandard regimens for primary inflatable penile prosthesis surgery.

Summary: MEMS/NEMS resonant sensors show potential in sensing minute masses and forces, but intrinsic noise limits their performance. Researchers propose a paradigm shift to use intrinsic thermal noise as the driving force, developing noise-driven sensors. These sensors detect stimuli by exploiting the dynamic amplified response to thermal noise at resonances and are suitable for nano-structures with low damping and high compliance. To overcome the phase incoherence of the driving force, three quantitative sensing mechanisms are developed. Experimental demonstrations of noise-driven pressure and temperature sensors validate the sensor paradigm, providing a new opportunity for the development of practical NEMS sensors.
