THE SOUND OF A GUITAR

"What can a guitar player do to change the sound of his/her guitar? What parameters or playing techniques does he/she have at his/her disposal to make special sound effects? How is performance technique related to changes in sound while playing the guitar? This paper presents a review of the literature regarding how different ways of plucking the string result in a different sound."

IMAGING SYSTEM FOR ULTRASOUND DRUG DELIVERY

"Although ultrasound imaging is probably best known for its diagnostic capabilities in echocardiography and prenatal care, ultrasonic waves can also be used for therapy by focusing an acoustic beam through the skin and into the body. An exciting application for focused ultrasound is localized delivery of drugs within the body. [Our] tracked imaging system can determine the ultrasound properties required for treatment so the ultrasound beam can be controlled to successfully activate drugs for tumor therapy."

BUGS COMMUNICATE THROUGH PLANTS

"Nezara viridula and other until now investigated species of the stink bug family Pentatomidae represent the model for optimizing long-range communication through green plants. They communicate with vibratory signals of the dominant frequency around 100 Hz, which travel through plants with low attenuation, creating standing wave conditions in the plants rod-like structures. Green plants act as low-pass filter, and their resonant peaks fit well
