Beta encoders are an alternative to traditional approaches to pulse code modulation.Eagle syndrome: Eagle syndrome (also termed stylohyoid syndrome styloid syndrome, styloid-stylohyoid syndrome, or styloid–carotid artery syndrome) is a rare condition caused by an elongated or deviated styloid process and/or calcification of the stylohyoid ligament, which interferes with adjacent anatomical structures giving rise to pain.Intravascular ultrasoundPrelingual deafness: A prelingual deaf individual is someone who was born with a hearing loss, or whose hearing loss occurred before they began to speak. Infants usually start saying their first words around one year.Frequency following response: Frequency following response (FFR), also referred to as Frequency Following Potential (FFP), is an evoked potential generated by periodic or nearly-periodic auditory stimuli.Burkard, R.Temporal analysis of products: Temporal Analysis of Products (TAP), (TAP-2), (TAP-3) is an experimental technique for studyingThumbprint sign: In radiology, the thumbprint sign, or thumbprinting, is a radiologic sign found on a lateral C-spine radiograph that suggests the diagnosis of epiglottitis. The sign is caused by a thickened free edge of the epiglottis, which causes it to appear more radiopaque than normal, resembling the distal thumb.Rotational angiography: Rotational angiography is a medical imaging technique based on x-ray, that allows to acquire CT-like 3D volumes during hybrid surgery or during a catheter intervention using a fixed C-Arm. The fixed C-Arm thereby rotates around the patient and acquires a series of x-ray images that are then reconstructed through software algorithms into a 3D image.Trophoblast: Trophoblasts (from Greek trephein: to feed, and blastos: germinator) are cells forming the outer layer of a blastocyst, which provide nutrients to the embryo and develop into a large part of the placenta. They are formed during the first stage of pregnancy and are the first cells to differentiate from the fertilized egg.CADgene: CADgene is a database of genes involved in coronary artery disease (CAD) .Countercurrent chromatographyStereocilia (inner ear): In the inner ear, stereocilia are the mechanosensing organelles of hair cells, which respond to fluid motion in numerous types of animals for various functions, including hearing and balance.

Like other types of [[incidental findings, it is found during the course of examination and imaging for other reasons.Champion INH Flat RaceGlossmeter: A glossmeter (also gloss meter) is an instrument which is used to measure specular reflection gloss of a surface. Gloss is determined by projecting a beam of light at a fixed intensity and angle onto a surface and measuring the amount of reflected light at an equal but opposite angle.Equivalent rectangular bandwidth: The equivalent rectangular bandwidth or ERB is a measure used in psychoacoustics, which gives an approximation to the bandwidths of the filters in human hearing, using the unrealistic but convenient simplification of modeling the filters as rectangular band-pass filters.Hearing (person): The term hearing or hearing person, from the perspective of mainstream English-language culture, refers to someone whose sense of hearing is at the medical norm. From this point of view, someone who is not fully hearing has a hearing loss or is said to be hard of hearing or deaf.
