Abstract: A linear accelerator comprises side-coupled cavity cells configured to accelerate electrons with a radio frequency field. The field amplitude in the initial cells is lower than in the later cells, and the initial cells are shorter than the later cells. This creates a capture section where electrons are captured and bunched while experiencing low acceleration, followed by an acceleration section where the bunched electrons experience stronger acceleration.

Abstract: A memory cell for storing one or more bits of information has a control gate, a source terminal and a drain terminal. A semiconductor substrate is located between the source and drain terminals, and a floating gate is disposed between the control gate and the semiconductor substrate. The floating gate is electrically isolated from the control gate by a charge trapping barrier, and is electrically isolated from the semiconductor substrate by a charge blocking barrier. At least one of the charge trapping barrier and the charge blocking barrier contains a III-V semiconductor material. The charge trapping barrier is adapted to enable the selective passage of charge carriers between the control gate and the floating gate, in use, to modify the one or more bits of information stored by the memory cell.

Abstract: The present invention relates to a method of diagnosing, or providing a prognosis to, or for providing the likelihood of developing, malignant melanoma in a subject, the method comprising the steps of: (a) measuring two or more markers in blood perfusion dynamics at and/or around a skin lesion site; and (b) determining if the two or more markers is different to a normal value. The invention also relates to a device for diagnosing/providing a prognosis to/for malignant melanoma in a subject.

Abstract: Methods treat neurological disorders, for example neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease and stroke. Particularly although not exclusively, GIP/GLP-1 co-agonist peptide is used in the treatment of such neurological disorders. Pharmaceutical compositions include a GIP/GLP-1 co-agonist peptide for use in treatment of such disorders.

Abstract: A method and apparatus for identifying similar and coordinated communications between computers connected by a network are described. Communications between a plurality of pairs of computers are monitored to obtain respective flow metrics for a first and second pair of computers. The flow metric represents at least one property of the data flow between the pair of computers. Representations of the evolution of the data flows between the pairs of computers are updated using the flow metrics. The representations of the evolution of the data flows are compared to determine the similarity of the data flows between the pairs of computers. The first pair of computers and the second pair of computers are identified as exhibiting similar and coordinated communication if their data flows are determined to be similar.

Abstract: A method for forming a polished facet between an edge and a face of a sample, involves removing a first portion of the sample by directing an ion beam onto the edge adjacent the first portion along an ion beam axis to leave the polished facet. The ion beam axis lies on an ion beam plane oriented at a glancing incident angle, preferably from 1° to 30°, to a sample plane defined by and parallel to the first face. The ion beam is directed to flow from the edge towards the first face. Also disclosed is a sample preparation apparatus comprising a chamber adapted for evacuation with a sample holder adapted to hold a sample comprising a first face bounded by an edge, and an ion gun arranged to direct an ion beam along an ion beam axis towards the sample.

Abstract: A method of forming a metal layer on an electrically insulating substrate comprises depositing a photocatalyst layer onto the substrate and depositing a mask layer comprising voids on the substrate, such as a layer of latex microparticles with voids between them, to give an open pore structure to the mask. An electroless plating solution is then provided on the photocatalyst layer, and the photocatalyst layer and electroless plating solution are illuminated with actinic radiation whereby deposition of metal from the electroless plating solution to form a metal layer on the photocatalyst layer is initiated whereby the metal deposits in the voids of the mask layer. The mask layer is subsequently removed to leave a porous metal layer on the substrate. The method allows for deposition of porous metal films with controlled thickness and excellent adhesion onto electrically insulating substrates. The method is suitable for providing metal layers with controlled, regular porosity.

Abstract: Computer implemented machine learning methods are described. A co-operative learning method involves a first rule based system and a second rule based system. A rule base is generated from input data and recursion data is used to recursively update the rule base as a result of newly received input data. Rule data defining at least one rule and associated data are sent to the second system which determines whether to update its rule base using the transmitted rule data, and if so the recursion data is used to recursively determine the updated rules for its rule base. A father machine learning method for a rule based system, involves receiving time series data, determining whether the data increases or decreases the spatial density for previously existing rules, and if so then creating a new cluster and associated rule, otherwise a new cluster is not created.
