摘要： An embodiment is directed to a method for selecting a predictive macroblock partition from a plurality of candidate macroblock partitions in motion estimation and compensation in a video encoder including determining a bit rate signal for each of the candidate macroblock partitions, generating a distortion signal for each of the candidate macroblock partitions, calculating a cost for each of the candidate macroblock partitions based on respective bit rate and distortion signals to produce a plurality of costs, and determining a motion vector from the costs. The motion vector designates the predictive macroblock partition.

摘要： The motion estimation techniques and video encoding device(s) described use a two dimensional pipeline to generate accurate motion estimation parameters for a current video block. The two dimensional pipeline uses previously calculated motion estimation parameters of relevant neighboring video blocks, including a preceding video block on a same row as the current video block, prior to the generation of the accurate motion vectors, motion vector predictors, and mode decision of the current video block The use of the two dimensional pipeline allows accurate motion vector prediction from neighboring video blocks previously not available, in the computation of motion vectors. Three engines may be used in the two dimensional pipeline, a fetch engine, an integer search engine and a fractional and spatial search engine. While the fetch engine and fraction and spatial search engine operate on one row, the integer search engine operates on another row.

摘要： The present invention relates to a modified perovskite comprising a polymer that co-crystalizes with perovskite. In particular instances, the polymer is chosen from poly(ethylene oxide) (PEO) or polyethylenimine (PEI). A modified perovskite film includes an ionic salt; and a perovskite having the formula ABX3, wherein counter anions of the ionic salt interact with A and counter cations interact with X, such that ion migration is suppressed.

摘要： Improved methods to quantitate RNA in biological or other analytical samples employ extended RNAs containing adaptors at the 5′ end and polyA sequences coupled to a tag at the 3′ end. The invention method is particularly useful in quantitating microRNAs as primers can be used that need not complement the non-conserved 3′ ends of these molecules.

摘要： A photodetector includes an active layer formed of an inorganic/organic hybrid perovskite material, such as organometal halide perovskites. The perovskite hybrid photodetector provides low dark-current densities and high external-quantum efficiencies, resulting in a photodetector with enhanced photoresponsivity and detectivity. Advantageously, the perovskite hybrid photodetector may be prepared by solution processing, and is compatible with large-scale manufacturing techniques.
