摘要:
A method of tracking the position of a body part, such as a hand, in captured images, the method comprising capturing (10) colour images of a region to form a set of captured images; identifying contiguous skin-colour regions (12) within an initial image of the set of captured images; defining regions of interest (16) containing the skin-coloured regions; extracting (18) image features in the regions of interest, each image feature relating to a point in a region of interest; and then, for successive pairs of images comprising a first image and a second image, the first pair of images having as the first image the initial image and a later image, following pairs of images each including as the first image the second image from the preceding pair and a later image as the second image: extracting (22) image features, each image feature relating to a point in the second image; determining matches (24) between image features relating to the second image and image features relating to in each region of interest in the first image; determining the displacement within the image of the matched image features between the first and second images; disregarding (28) matched features whose displacement is not within a range of displacements; determining regions of interest (30) in the second image containing the matched features which have not been disregarded; and determining the direction of movement (34) of the regions of interest between the first image and the second image.
摘要:
The invention relates to a method for identifying compounds that act as modulators of hepatitis C (HCV) translation and/or replication, and to compounds identified by this method, and their uses in medicine. The invention also relates to an RNA useful for identifying modulators of HCV translation and/or replication. The invention further relates to a method for producing a replication-competent HCV virus.
摘要:
Apparatus comprises a pipet comprising first and second channels separated by a septum and having a tip at which each of the first and second channels is open; an electrolyte solution contained within both the first and second channels of the pipet; a first electrode extending into the electrolyte in the first channel of the pipet; a second electrode extending into the electrolyte in the second channel of the pipet; means for applying a potential difference between the first and second electrodes; means for measuring alternating current components of a current flowing to or from the first electrode; means for applying an oscillatory perturbation to the pipet; and means responsive to the alternating current measured to be flowing to or from the first electrode to adjust a position of the pipet such as to control a separation between the tip of the pipet and a surface of interest.

The invention concerns the role of Glo 1 in the prevention and reversal of proteomic and genomic damage by dicarbonyl substrates thereof and, in particular, therapeutics that promote Glo 1 production.
摘要:
The invention relates to virology and the prevention and/or treatment of viral infection and disease in animals, including birds and humans. The invention relates to the field of antiviral treatments. The invention further relates to methods of stimulating innate immunity and natural interferon production in humans or animals and in component parts of humans or animals, including cells and tissues. The invention also relates to the field of defective interfering (DI) viruses, including cloned DI viruses.
摘要:
The invention provides a process for the production of a monolithic implant for use in tissue engineering, the process comprising the steps of plasticising at least one biocompatible material into a paste, extruding the paste through a die, and drying the extruded material to eliminate an aqueous and/or non-aqueous component. The invention also relates to a monolithic implant as thereby manufactured, and the use of such an implant as a scaffold for tissue-engineering and as a transplant tissue in reconstructive or replacement surgery.
摘要:
The use of dewatered small particle tailings material derived from the industrial washing of coal, metal ores, rocks and extracted minerals as a component of casing material for the cultivation of mushrooms ( Agaricus bisporus and other Agaricus spp.) is described.
摘要:
A loudspeaker system comprises a flexible paper or plastics diaphragm 1 for displacing a quantity of a transmitting medium to generate sound, waveform-sampling circuitry for supplying a series of sample drive signals of varying amplitude indicative of the amplitudes of an electrical input signal having an audio waveform at a series of sampling points distributed over a period of the waveform, and a piezoelectric actuator 4 for actuating the diaphragm 1 in response to each of the drive signals supplied by the waveform-sampling circuitry to cause corresponding displacement of the transmitting medium such that the combined effect of such displacement by all the drive signals is to produce a synthesised sound wave within the transmitting medium mimicking the waveform of the input signal
