    摘要： An architecture for a very large scale integrated (VLSI) implementation of a finite imprise response (FIR) digital filter having no multipliers and a coefficient space limited to powers of two. The filter structure includes a data bus, a coefficient bus and a sum-in bus to each coefficient tap. Each tap has a coefficient and control word register which is loaded during an initialization phase of the filter. Multiplication is provided by a shifter which provides the correct power of two weighting of an input data sample. The weighted data sample at each tap is added to the output of the previous tap. This architecture results in a regular, modular structure which can be cascaded and which is programmable for various data word lengths and coefficient spaces.

    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： 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.
