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.
The way that inverse ETFs work. Inverse ETFs offer investors a chance to match the opposite of the return of an underlying index each day. For instance, if the S&P 500 falls 1%, then the way that the Short S&P 500 ETF is set up, its price should rise by 1%. The same concept applies to leveraged inverse ETFs, except that the returns are multiplied. For the UltraShort S&P 500 ETF, a 1% decline in the index should produce a 2% rise for the fund shares. Inverse ETFs use different methods to produce these results.
