Abstract: A method including: dividing a first video frame into a predetermined plurality of regions; assigning a quantization parameter to each of the predetermined plurality of regions in accordance with a first predetermined pattern of quantization parameters, the quantization parameters not being all the same; dividing video frames, subsequent to the first video frame, into the predetermined plurality of regions; and assigning a quantization parameter to each of the predetermined plurality of regions in the video frames subsequent to the first video frame, in accordance with another predetermined pattern, different from the first predetermined pattern.

Abstract: The present invention relates to an apparatus for the isolation of extracellular vesicles from human fluid, and more particularly, to an apparatus comprising a channel formed on a microchip and a porous polymer monolith filter connected to the channel. The apparatus can be used to the diagnosis of disease including cancer from vesicular nucleic acid in a non-invasive manner. Capable of isolating and purifying a large quantity of vesicles from a small amount of a body fluid sample within a short time, the apparatus is expected to be advantageously and widely applied in the medical research and clinical diagnosis of disease including cancer.

Abstract: In video coding, where differences between input picture values and picture prediction values are transformed in a block based transform, the differences are formed in a series of parallel steps. A first step conducted in parallel upon a first subset of pixels uses prediction values based wholly on previously processed blocks. This first subset can include anchor pixels which are not contiguous with any previously processed block. A second step conducted in parallel upon a second subset includes pixels which are predicted from pixels of the first subset.

Abstract: An image encoder utilising a transformation operating between a spatial domain and a DCT or other transform domain, employs the steps of forming a prediction; subtracting the prediction to form a difference; and quantising the difference in a transform domain, where the prediction is formed in the transform domain and the transform domain prediction is weighted.

Abstract: In a method of video coding, in which a difference is formed between input picture values and picture prediction values and that difference is transforming with a DCT, the picture prediction is formed as: P=(1?c)Pc+CPo where Pc is a closed loop predictor which is restricted to prediction values capable of exact reconstruction in a downstream decoder and Po is a spatial predictor which is not restricted to prediction values capable of exact reconstruction. The factor can vary from zero to unity depending on a variety of parameters.

Abstract: Piperidine derivatives and pharmaceutically acceptable derivatives thereof useful in methods of treatment of bacterial infections in mammals, particularly in man. The piperidine derivatives include compounds of formula (I): wherein RA, AB, n, R3, R2 and R4 are defined herein. For example, RA is an optionally substituted bicyclic carbocyclic or heterocyclic ring system, and R4 is a group U-R5 in which R5 is an optionally substituted bicyclic heterocyclic ring system as defined herein (e.g. optionally substituted pyrido [3,2, -b][1,4] thiazin-yl).
