Abstract: The invention provides a method of preventing or reducing the growth of crystals in a substance which is susceptible to crystal growth in which colloidal particles having an amphiphilic structure, e.g. Janus particles, are contacted with the substance. Colloidal particles suitable for use in the invention include cross-linked, colloidal materials formed from hydrophobic monomers such as acrylates or methacrylates and hydrophilic monomers such as those derived from acrylic and/or methacrylic acid. The colloidal particles find particular use in methods of cryopreservation of biological samples (e.g. cells, tissues or organs), as a texture modifier in frozen food products, in the inhibition of gas hydrate formation, and as scale inhibitors.

Abstract: A vehicle has a vehicle body and a vehicle bonnet assembly. The vehicle bonnet assembly includes a bonnet 14 hinged at its front to the vehicle body 10 and latched at its rear by two latch devices. Each latch device comprises a latch assembly 17 mounted to the vehicle body 10 and a striker 21 mounted to the bonnet 14. Impact sensors are configured to detect a front collision with a pedestrian and two lift actuators 18 are arranged to raise the rear edge of the bonnet 14 into a deployed position in response to a pedestrian impact. Each latch assembly 17 includes a latch claw 26 moveable between a latch position in which the striker 21 is held by the latch claw 26 and a release position in which the striker 21 is releasable from the latch claw 26. Each latch assembly 17 also includes a release member 27 which is operable by a driver of the vehicle to allow the latch claw 26 to be moved towards its release position and allow the bonnet 14 to be lifted.

Abstract: The prosthesis device can have a pair of articular members adapted to be mounted onto adjoining bones, respectively, to replace a joint. The first and second articular members can have first and second bearing elements, respectively. The bearing elements can be formed to be capable of replacing at least a portion of the bone ends of the adjoining bones, respectively, and providing an articulation close to that of a natural joint. The bearing elements can be fixed to the respective bones through an initial implant fixation achieved by press-fit anchoring immediately after surgery and/or a secondary implant fixation established from bone-ingrowth.

Abstract: A method (500) of generating a matching key (599) for an image (501) is disclosed. The matching key (599) is substantially invariant to rotation, scale and translation. The method (500) starts by forming a spatial domain representation of the image (501) that is substantially invariant to translation of the image (501). Rotation and/or scaling in the spatial domain representation is next transformed (580) into translation to form a transformed image. A representation of the transformed image is then formed that is substantially invariant to translation of the transformed image. The representation of the transformed image is the matching key (599) for the image (501).

Abstract: A graphics processor performs graphical operations on graphical objects represented in an external data format. The graphics processor includes a setup unit, first and second mapping units, and a calculator. The setup unit sets up one or more registers reflecting a current instruction. The first mapping unit maps, responsive to the current instruction, the external data format to at least one corresponding internal data format selected from a set of internal data formats. The calculator performs graphical operations on the graphical objects when in one of the selected internal data formats. The second mapping unit maps, responsive to the current instruction, each internal data format in the set of internal data formats to the external data format after the graphical operations have been performed.
