    Abstract: The invention relates to a superconducting electrical switch. The switch comprises two parallel branches of superconducting material in a loop, and a magnetic field generator which generates a time-varying magnetic field through the loop in a direction generally parallel to the axis of the loop. The magnetic field generator is selectively activated and de-activated to switch the electrical switch between a low-resistance state and a higher-resistance state. In the low-resistance state, there is no magnetic field through the loop and transport current flows through the loop. In the higher-resistance state, a magnetic field through the loop induces a screening current such that the sum of the transport current and the screening current is substantially equal to the critical current or is greater than the critical current of the superconducting material. The switch may be used in, for example, a rectifier or fault current limiter.

    Abstract: A polymer composition for impregnating a high temperature superconductor (HTS) coil, the composition comprising: a polymer resin, a plurality of particles of a first filler material, and a plurality of particles of a second filler material; wherein the median particle size of the second filler material is less than the median particle size of the first filler material. The polymer composition may be used to prepare a polymer impregnated HTS coil having a predetermined turn-to-turn spacing. A property of the polymer composition may also be modified, for example, the coefficient of thermal contraction and/or resistivity of the composition. Also disclosed is a polymer impregnated HTS coil and a method for preparing the coil.

    Abstract: An asymmetric magnet for use in performing MRI of a patient's head. The magnet has a patient end. The magnet provides an offset imaging volume (35) in a recess with an isocentre that is positioned closer to the patient end than an opposite end. The magnet has at least three groups of coils (44, 45, 46) in a generally tapering arrangement. The magnet also has an additional group of coils (47). A first group of coils (44) overlaps the additional group of coils (47), such that a bottom portion (47") of the additional group of coils (47) is positioned closer to the patient end of the magnet than a top portion (44') of the first group of coils (44).

    Abstract: A modular and hierarchical DNA assembly platform for synthetic biology is described. This enabling technology, termed MIDAS (for Modular Idempotent DNA Assembly System), can precisely assemble multiple DNA fragments in a single reaction using a standardised assembly design. It can be used to build genes from libraries of sequence-verified, reusable parts and to assemble multiple genes in a single vector. We describe the design and use of MIDAS, and its application in the reconstruction of the metabolic pathway for production of paspaline, a key intermediate in the biosynthesis of a range of indole diterpenes — a class of economically important secondary metabolites produced by several species of filamentous fungi.

    Abstract: A magnet (7) for use in an apparatus (1) for performing magnetic resonance imaging (MRI) of a patient's head is an asymmetric magnet (7) comprising a plurality of coils (45, 46, 47) that are aligned along a cylindrical axis (29) to provide a magnetic field on the cylindrical axis (29). The magnet (7) has a patient end (23) arranged to be positioned adjacent or against a patient's shoulders with the patient's shoulders outside the magnet (7). The magnet has a recess (27) for receipt of the patient's head and extending into the magnet (7) from the patient end (23). The magnet (7) is configured to provide an imaging volume (35) that is positioned along the cylindrical axis (29) of the magnet (7) in the recess (27), and at least a major part of the imaging volume (35) has a substantially linear non-zero magnetic field gradient along the cylindrical axis (29).
