摘要:
This invention provides gene-specific probe labeling methods for nucleic acid array detection. In the subject invention, a set of a representational number of distinct gene specific primers is used to generate a sub-population of labeled nucleic acids from each of the different physiological samples. The labeled nucleic acids are then compared to each other by hybridizing to a specially designed nucleic acid array that contains the representational number of distinct genes. The subject methods find use in identifying the expression pattern of the genes of special interest in the physiological samples.

Provided is a masking system of masks for use with multiwell plates such as microtiter plates to facilitate sample dispensing and assay accuracy, especially when dispensing more than one solution into the wells. One or more masks, adapted in size to fit snugly over a multiwell plate and the mask formed with openings each aligned with a subset of one or more wells of the plate beneath, aids the user in sample and/or reagent administration. Advantageously, the masks contain registration aids so that proper orientation with respect to the plate below is achieved; the registration aid may be a cut corner, registration peg or mark, or visual marking or stamping.

Methods, systems, and computer programs for encoding and decoding image are described. In some aspects, an input data block and a prediction data block are accessed. A projection factor is generated based on a projection of the input data block onto the prediction data block. A scaled prediction data block is generated by multiplying the projection factor by the prediction data block. A residual data block is generated based on a difference between the input data block and the scaled prediction data block. In some aspects, a prediction data block, a residual data block, and a projection factor associated with the residual data block are accessed. A scaled prediction data block is generated by multiplying the projection factor by the prediction data block. An output data block is generated by summing the residual data block and the scaled prediction data block.
摘要:
Encoding and decoding methods that perform quantization using adaptive reconstruction levels are presented. The reconstruction levels for a given partitioning of the data space may be selected based upon the distribution of data points within each sub-part defined by the partitioning. In some cases, the adaptive reconstruction levels may be based upon an average of the data points within each sub-part. In some cases, the adaptive reconstruction levels may be selected using a rate-distortion analysis including the quantization distortion associated with the levels versus the data points and the rate associated with transmitting the encoded adaptive reconstruction levels. The methods relate to data compression in a range of applications including audio, images and video.
摘要:
A method of encoding video data using soft decision quantization makes use of iterative encoding to provide the ability to optimize encoding across different functional elements in a hybrid video encoder. Iterative encoding is used to allow quantization step size, motion prediction and quantization levels to be optimized despite their interrelated nature.
摘要:
A transcoder and methods of encoding inter-prediction frames of a downsampled video wherein the downsampled video is a spatially downsampled version of a full-resolution video. Full-resolution motion vectors are downscaled and each downscaled motion vector pinpoints a search area within a reference frame. The union or combination of search areas defines the search field for candidate motion vectors. A motion vector is selected from the candidates based on realizing a minimum rate-distortion cost.

A transcoder and methods of encoding inter-prediction frames of a downsampled video wherein the downsampled video is a spatially downsampled version of a full-resolution video. Full-resolution motion vectors are downscaled and a weighting factor is calculated for each downscaled motion vector based upon the transform domain residual coefficients associated with that full-resolution motion vector. A motion vector prediction is made based on the weighted average using the downscaled motion vectors and their weighting factors.

This disclosure relates generally to adhesives and particularly to reversible adhesives. This disclosure further relates to generally adhesive articles and particularly to wound dressings comprising such adhesives. The adhesive comprises a core and a shell comprising at least two components. One of the components of the shell comprises a polymer formed by reacting a monomer of a thermally reversible polymer and the other component comprises a polymer formed by reacting a monomer of a polymer of a pressure sensitive adhesive. The wound dressing comprises a substrate and the reversible adhesive, forming a reversible wound dressing. Such wound dressings are particularly suitable for treatment of damaged sensitive tissue, for example wounds formed on a fragile skin.
