Abstract:
A method of authenticating a target device using a reader and a data store comprising: sending a selected challenge data value from the reader to the target device multiple times; receiving at the reader the respective response data value generated by the target device in response to each instance of the challenge data value sent by the reader; determining a representative response data value from the response data values received by the reader; comparing the representative response data value against the response data values in the respective challenge-response data set; and determining that the target device is authentic if the representative data value matches any one of the response data values from a respective challenge-response data set.
Abstract:
The present invention relates to a method for a method for predicting the development of renal dysfunction in a subject following physical trauma, hypotension, sepsis and/or septic shock syndrome, wherein the method comprises the steps of:- a. determining the level of an anti-inflammatory cytokine present in a sample taken from the subject after physical trauma, after a hypotensive event, after sepsis, and/or after septic shock syndrome; b. predicting the development in the subject of renal dysfunction on the basis of the level of an anti-inflammatory cytokine determined in step a).
Abstract:
A process for the separation of organic compounds comprises centrifugal partitioning of at least one organic compound between a mobile liquid phase and an immiscible stationary liquid phase. At least one of the mobile liquid phase and the stationary liquid phase comprises or consists of an ionic liquid. A rotary coil centrifuge for counter current chromatography and a liquid-liquid chromatography or liquid-liquid extraction apparatus may be used in the process.

Abstract:
The present disclosure relates to improvements in or relating to pattern recognition, and in particular to a novel systems and methods for pattern recognition, and to devices incorporating such systems and methods. In particular, a spectral analysis is performed on a candidate pattern to obtain a set of observation vectors. The observation vectors are decoded to produce a candidate match between the observation vectors and entries from a knowledge source. The step of decoding the vectors comprises modelling the knowledge source as a weighted finite state transducer (WFST) and the step of decoding comprises modelling the propagation of tokens through nodes of the WFST for observation vectors derived from successive frames of the candidate pattern. For each successive propagation, a list of tokens is sorted in order of their associated cost, and a pruning step is applied to remove tokens from said sorted list which go beyond a pre-determined cost threshold, before performing the next iteration.
Abstract:
The present invention relates to a process for the removal of naphthenic acids from crude oils and crude oil distillates by use of supported basic ionic liquids.
Abstract:
A method of ageing a catalyst material comprising at least the steps of: (a) heating a gaseous stream; (b) adding a least one pure hydrocarbon gas and an oxygen-containing gas to the heated gaseous stream to provide a combined stream; and (c) passing the combined stream through the catalyst material. The use of at least one pure hydrocarbon gas and an oxygen-containing gas allows the present invention to maximise re-circulation of the exit stream from the catalyst material for reuse, whist maintaining the correct C, H and O proportions being provided in the combined stream to replicate realistic use of the catalyst material.
Abstract:
A retrodirective antenna system (1) for receiving an incoming signal (15) from an object (13) and directing an outgoing signal (11) back to the object (13), comprising two or more transceiver cells (3), each of which receives a part of the incoming signal, produces a phase conjugate output signal, which output signals from the cells combine to form an outgoing signal (11) directed back to the object (13), wherein each transceiver cell (3) comprises an antenna component (7) which detects the part of the incoming signal, a processor which receives the part of the incoming signal and produces first and second same-side, sideband (SB) signals of the part of the incoming signal, a phase shift system comprising a first phase element which receives the first SB signal and outputs a SB signal having a first phase, and a second phase element which receives the second SB signal and outputs a SB signal having a second phase which is in quadrature with the first phase, and an IQ modulator comprising an I input port, a Q input port and a phase adjuster, which receives the SB signal having the first phase on the I input port and the SB signal having the second phase on the Q input port, or receives the SB signal having the first phase on the Q input port and the SB signal having the second phase on the I input port, and phase adjusts the SB signals to produce an output signal which is the phase conjugate of the part of the incoming signal.
Abstract:
The present invention relates to the use of ionic liquids as antimicrobial agents, and to the use of antimicrobial compositions comprising an ionic liquid, a film-enhancing composition and a viscosity controlling agent. The invention further relates to methods of disinfecting substrate surfaces, to substrates produced by such methods, and to novel ionic liquid compositions.
Abstract:
The invention relates to fragments of Chromogranin A (CgA) derived peptide fragments and their use in methods of therapy, for example in the treatment of diabetes etc. The peptides, for example AL-11, GV-19 and WE-14, are tropic, i.e stimulate release of regulatory substances and may be used in the absence of a stimulatory concentration of glucose.
