Abstract: A footwear article includes a heel structure that returns an ankle collar from a second state that is conducive to donning up to a first state that secures the wearer's foot during wear. The footwear article includes an upper having a foot insertion opening. The foot-insertion opening defines a first circumference when the heel structure is in the first state, and wherein the heel structure expands the foot-insertion opening to a second circumference when the heel structure is in the second state, such that the second circumference is larger than the first circumference.

Abstract: A footwear article includes a footwear upper defining a foot-receiving cavity with a heel region and defining an ankle opening, the footwear upper including an ankle collar at the ankle opening. The footwear article has a sole structure secured to the footwear upper and underlying the foot-receiving cavity, the sole structure including a strobel and a midsole. The footwear article including a collar support disposed inward of an exterior layer of the footwear upper at the heel region, and extending from the sole structure to the ankle opening. The ankle collar is movable from a raised state positioned farther from the sole to a lowered state positioned closer to the sole during donning, and wherein the collar support has a shoehorn structure operable to move a portion of the ankle collar rearward in a longitudinal direction as the ankle collar moves from the raised state to the lowered state.

Abstract: An optical waveguide arrangement is provided which comprises an active ridge waveguide structure 12 formed by etching of a semiconductor substrate 1, 2, 3. There is also provided an auxiliary waveguide-like structure 8 formed on the substrate adjacent the active ridge waveguide structure 12 to control the etched profile of the active waveguide structure. The arrangement of the auxiliary structure 8 on the substrate controls the etched profile over the cross-section of the active waveguide structure 12 and along the length of the active waveguide structure 12. Advantageously, this arrangement reduces or eliminates the disadvantages associated with etch-process induced asymmetries in the shape of closely spaced waveguides.

Abstract: A system includes a memory and a processor communicatively coupled to the memory. The memory stores a correlation index that is based at least in part on a portfolio of index options, a plurality of stock options, and a plurality of deltas computed using a plurality of constant flat implied volatilities. The processor determines a value of the correlation index by selecting a plurality of strike prices for each of the index and stock options, computing a constant flat implied volatility for an index and a plurality of stocks on a first date, and computing the plurality of deltas using the plurality of constant flat implied volatilities.

Abstract: Methods and compositions useful in the treatment or prevention of synucleinopathies, such as Parkinson's Disease, Diffuse Lewy Body Disease, and Multiple System Atrophy, or other neurodegenerative diseases are provided. The treatment including administering to a subject a farnesyl transferase inhibitor compound.

Abstract: The present invention relates to a lightweight boss system for use on a tank or pressure vessel. The boss system is preferably made of a composite or resin transfer molded (RTM) material. It is particularly useful for composite tanks, such as filament-wound composite tanks.

Abstract: A composite membrane comprises an inorganic support having interstices and porous inorganic films of sintered non-metallic particles carried by the support and bridging the interstices thereof. The support is preferably a woven metal mesh, with the films substantially coplanar with the support. The films may be formed by applying a suspension of refractory particles in a polymer solution to bridge the interstices of the support, and heating the films to partly sinter the particles. Since the films are in compression at ambient temperature, any cracks that may be formed by damage to the composite membrane tend not to propagate.

Abstract: Fibre-reinforced structures comprising a thermoplastics polymer and containing at least 30% by volume of reinforcing filaments extending longitudinally of the structure which have been produced in a continuous process and which have exceptionally high stiffness. The exceptionally high stiffness results from thorough wetting of the reinforcing filaments by molten polymer in the continuous process. The thorough wetting gives rise to a product which can be further processed even in vigorous mixing processes such as injection moulding with surprisingly high retention of the fibre length in the fabricated article. The continuous processes for producing the reinforced structures employ thermoplastics polymers having lower melt viscosities than conventionally considered suitable for achieving satisfactory physical properties.

Abstract: Fibre-reinforced structures comprising a thermoplastics polymer and containing at least 30% by volume of reinforcing filaments extending longitudinally of the structure which have been produced in a continuous process and which have exceptionally high stiffness. The exceptionally high stiffness resluts from thorough wetting of the reinforcing filaments by molten polymer in the continuous process. The thorough wetting gives rise to a product which can be further processed even in vigorous mixing processes such as injection moulding with surprisingly high retention of the fibre length in the fabricated article. The continuous processes for producing the reinforced structures employ thermoplastics polymers having lower melt viscosities than conventionally considered suitable for achieving satisfactory physical properties.

Abstract: Infra-red radiation detectors are used in gas turbine engines to detect radiation produced by the turbine blades giving an indication of blade temperature. Above a given limit the signal produced by the detector is passed to the fuel control system to shut down the fuel supply to the engine. An additional detector is provided which receives the same image as the first detector but is biased to detect radiation in the visible light part of the spectrum. When incandescent particles pass through the field of vision of the detectors both show an increase in signal due to both types of radiation being increased during this transient event. The signal from the second detector is used to reduce the signal from the first detector by an amount sufficient to prevent the fuel supply being temporarily shut down.
