    摘要： A hashing data storage and retrieval arrangement whose storage capacity is unaffected by collisions. A first memory serves as a hash index table, for storing pointers at each address location corresponding to a hash value generated by hashing a key data word. Each pointer is the address of a location in a second memory, which has a separate storage location for each key data word, its associated data, and a further pointer which is the address of the next key data word resulting from a collision during hashing. Preferably a pipeline register between the two memories permits hashing of a subsequent key data word while accessing of the second memory is still in progress.

    摘要： Methods for the measurement and prediction of response to hepatotoxicants and carcinogens through the detection of metabolites in a mammal are provided. The metabolites can be used as biomarkers, including efficacy biomarkers, surrogate biomarkers, and toxicity biomarkers. The methods find use for early prediction of toxicity, target identification/validation, and monitoring of drug efficacy.

    摘要： Device for splitting a digital interlaced television signal into components in which interlaced frames are applied to a vertical low-pass filter (6). To prevent motion artefacts in the spatial signal thus obtained, the interlaced frame is also applied to a vertical high-pass filter (8). This vertical high-pass filter supplies a motion auxiliary signal which may have a small vertical bandwidth. When combining the spatial signal and the motion auxiliary signal, noticeable motion artefacts do not occur in the interlaced frame. The device may be used for deriving a standard television signal from a high-definition television (HDTV) signal and for compatible transmission of HDTV signals.

    摘要： A decoder for data encoded in a form combining a prefix which is a previously coded sub-string and a next data element in the data stream. The decoder includes memories for storing code words and data separately. Upon receipt of a code word the decoder stores the previously received code word, applies the newly received word to the code word memory to obtain the location of the last data element which is part of the data represented by the newly received code word, and another code word associated with the prefix. Upon completion of decoding the latest code word, the first data element of the decoded word is appended to the next previously received code word, and the combination is stored as the equivalent of a code word which is next after the highest code word already received. At least one memory is shared for use during encoding and decoding.
