Measurements have shown that the sound-induced motion of free-standing stereocilia of hair cells in the alligator lizard cochlea exhibits tonotopically organized frequency selectivity that is correlated with the geometry of the stereociliary tuft. We propose a model in which basilar-membrane motion causes vibration of the receptor organ which drags the(More)

Results Student nurses’ vaccination rates were 15.7% for Seasonal Influenza vaccine and 5.4% for Influenza A (H1N1) vaccine. Findings revealed a relationship between vaccination uptake rates and knowledge and risk perception and student nurses’ perceived health locus of control (p<0.05). The results also described the different level of student nurses’(More)
A model of the signal-processing properties of the macromechanical system of the alligator-lizard middle and inner ear is developed. The model is based on measurements (as a function of tone frequency) of ossicular and basilar-membrane motion and of acoustic input-admittance at the tympanic membrane before and after alterations of middle-ear and inner-ear(More)
A model is described for mechanoelectric transduction in hair cells with free-standing stereocilia in the alligator lizard cochlea. The model relates the angular displacement of the stereocilia to the receptor potential in the absence of the hair cell's membrane capacitance whose effect is considered elsewhere (Leong and Weiss, 1985, in preparation). The(More)
Protein tertiary structures exhibit an observable degeneracy in nature. This paper examines the connection between a protein motif’s abundance in nature and its designability as measured by in silico methods. After generating a set of protein structures, we evaluated each structure’s abundance in nature, ratio of possible contacts (contact degree) and in(More)
