STUDY ON THE PROSTHESIS STRUCTURAL DESIGN AND VIBRATION CHARACTERISTICS BASED ON THE CONDUCTION EFFECT OF HUMAN MIDDLE EAR

Study on the Prosthesis Structural Design and Vibration Characteristics Based on the Conduction Effect of Human Middle Ear

As a bridge from the sound signal in the air to the sound perception of the inner ear auditory receptor, the tympanic membrane and ossicular chain of the middle ear transform the sound signal in the outer ear through two gas-solid and solid-liquid conversions.In addition, through the lever principle formed by three auditory ossicle structure, the s

Genetic analysis reveals hidden threats and new motivation for conservation translocation of black-tailed prairie dogs at the northern limit of their range

Biodiversity loss continues at unprecedented rates; to slow loss, conservation practitioners are working to remove species from risk of extinction.But, even when species are no longer at risk of extinction, they likely exist in small, isolated populations, especially at range edges, and their long-term persistence is uncertain.The northernmost popu
