This paper describes the results of an investigation which examined the efficacy of a feedback equalization algorithm incorporated into the Central Institute for the Deaf Wearable Digital Hearing Aid. The study examined whether the feedback equalization would allow for greater usable gains when subjects listened to soft speech signals, and if so, whether or not this would improve speech intelligibility.

This paper is a review of a study to determine the sensation level at which the best discrimination and recognition occurs for severely and profoundly deaf children and the effect of distortion (peak clipping) has on the child's ability to recognize speech.

This paper reviews a study to determine if deaf children can discriminate fine durational changes in acoustic signals or whether the impairment of the peripheral auditory system interferes with the temporal precision necessary for such tasks.

Three separate theories of inhibiting cisplatin-induced apoptosis were investigated utilizing different cellular mechanisms. Specifically, the copper transport cycle, TRPV1, and the JNK pathway were inhibited and immunohistochemistry was performed to determine levels of apoptosis. All three resulted in statistically significant effects; increasing CuSO4 levels resulted in increased apoptosis, and inhibiting TRPV1
