Abstract: An air traffic control system, for use by a human controller controlling a plurality of aircraft held vertically separated in a stack above a minimum stack level, the system comprising at least one processor, and a display device for the human controller, controlled by said at least one processor; further comprising: means for periodically inputting a value representative of local terrestrial air pressure conditions; means for periodically inputting an aircraft flight level reading representing an altitude defined by a reference air pressure measured on the aircraft; means for periodically generating a display on said display device comprising a plurality of flight levels vertically arranged; means for indicating in said display said plurality of aircraft, arranged in a vertical list ranked by flight level; said at least one processor being arranged, on reception of a new said value, to redetermine said minimum stack level and to vary said display so as to indicate changes to said minimum stack level.

Abstract: A novel member of the RAET1/ULBP family of proteins (RAET1G) is identified and characterised and shown to bind the UL16 and NKG2D receptors with high affinity. RAET1G exhibits restricted expression in normal tissues but exhibits high levels of expression in tumours and may be differentially spliced in cancer cells to produce a soluble protein. RAET1G is also up-regulated in inflammatory diseases such as coeliac disease. RAET1G may be used as a novel marker for disease conditions including cancer conditions and inflammatory diseases.

Abstract: A process of dealing and drawing cards is provided wherein a player hand including N cards is dealt to the player from a computer card deck. An opponent hand including N cards is dealt to the opponent from the deck. The player and the opponent are provided with opportunity to draw cards. A gaming system determines which cards of the initial opponent hand to hold and which to discard using a play strategy-lookup table in accordance with the present invention. The strategy look-up table is addressed using an address set including all possible hands that could be dealt in an N card poker game. Each address of the address set stores a corresponding optimal hold scenario which provides information indicating which of the particular N cards of a hand to hold and which to discard in order have the greatest probability of winning. Cards are discarded from the initial opponent hand according to the look up table.
