A semiconductor device in one embodiment includes a depletion junction, a peripheral region adjacent the depletion junction, and a buffer layer. The carrier may be mixed with white phosphorus above its melting point, so that liquid phosphorus is pulled into the pores of the carrier by capillary action. According to the present disclosure, the prediction accuracy may be increased when encoding or decoding videos so that video encoding efficiency can be improved. The information relates to an instrument corresponding to each track available in the synthetic audio file. Move-out notifications are provided to allow removal of changed items from replicas when the change in the item takes that item outside of the interest set of the replicas.
