Abstract: A system, devices, and methods are described for imaging and measuring the mechanical properties of both surface and subcutaneous tissues found in living organisms, animals, and in natural and synthetic materials, and may include a first device configured to determine a modulus of a portion of bulk material or subcutaneous tissue (via measurement of vibrations), and/or determine resonant frequency of the vibrations, and a second device operably connected to the first device and configured to generate vibrations. The first device may be an optical coherence tomography device. The system may include a processor and data storage device with instructions which when executed by the processor, cause the processor to process of the frequency data and the displacement data to determine a resonant frequency of the material under investigation and calculate the mechanical modulus of elasticity of the material from a resonance frequency spectrum of the analyzed spectral image.

Abstract: A method of generating a result of a racing game having a plurality of participants to enable fixed odds betting on the racing game. The result of the racing game is generated from the result of an identifier selection game. The method comprises allocating unique subsets of a set of identifiers used in the identifier selection game to each of the plurality of participants, defining a ranking of said participants from highest to lowest, running said identifier selection game by randomly selecting a result subset of identifiers from the set of identifiers, and determining first place in said race by determining which of said plurality of participants has the most identifiers of said result subset in the participant's allocated subset, and if two or more participants have the same number of identifiers in their respective allocated subsets, determining first place by determining which of the two or more participants is ranked highest.

Abstract: A two-stroke motorcycle lubricant comprising a base oil having a viscosity at 100° C. of less than 8 cSt and a pour point below −30° C., preferably below −39° C. The two-stroke motorcycle lubricant further comprises a detergent system based on an ashless, oil-soluble amine. The two-stroke motorcycle lubricant exhibits high levels of cleanliness and low levels of exhaust smoke, whilst maintaining high load carrying capacity. The two-stroke motorcycle lubricant may be dyed.
