Light sensitivity is caused by a number of conditions that affect the eye (such as iritis, uveitis, and keratitis), as well as conditions that affect the entire body. Migraine headache is a common cause of photophobia, with a majority of migraine sufferers reporting sensitivity to light.
bNewQmatrix. Indicates which new inverse-quantization matrices are present in an inverse-quantization matrix buffer. Each element in this array corresponds to an inverse-quantization matrix type and indicates whether a new inverse-quantization matrix of that type is present in the buffer.he DXVA_QmatrixData structure is sent by the host decoder to the accelerator to load inverse-quantization matrix data for off-host bitstream compressed video picture decoding.
Definition. An inverse agonist is a molecule that binds to the same site as an agonist and is considered to be a full agonist. However, it elicits the opposite effect to that of a normal agonist, i.e.: demonstrates negative efficacy.n antagonist reduces the effect of an agonist by preventing it from binding to receptors. Both antagonists and inverse agonists reduce the activity if a receptor and, in the presence of an agonist, reduce its activity.
