Abstract: In a management of taxonomic information, a name that specifies an organism is identified. Based on the name and a database of organism names or classifications, another name that specifies the organism and that represents a link between pieces of biological identification information in the database, or a classification for the organism, is determined. Based on the other name or the classification, information associated with the organism is identified.

Abstract: An ultrafast sampling system includes an interposer and a sampler that include series of Schottky diodes configured with a non-parallel waveguide to form shocklines or nonlinear transmission line (NLTLs) that produce a differential strobe pulse. The shocklines are defined by non-parallel conductors that are configured as, for example, triangular, dentate, arcuate, or other shapes, or as conductors that have edges that are triangular, dentate, arcuate, or the like. The conductors are defined with respect to a substrate, and are airbridged so that at least some portions of the conductors are displaced from the substrate to reduce waveguide capacitance. Electrical connection to the sampler is made with airline having a inner conductor that is deformable to contact an input pad defined on the sampler.

Abstract: Methods of increasing cache capacity are provided. A method of increasing cache capacity is provided wherein original data are received in a cache with access to one or more variants of the original data being required, but the variants do not reside in the cache. Access is provided to the variants by using one or more delta data operable to be applied against the original data to produce the variants Moreover, a method of reducing cache storage requirements is provided wherein original data and variants of the original data are identified and located within the cache. Further, delta data are produced by noting one or more differences between the original data and the variants, with the variants being purged from the cache. Furthermore, a method of producing derivatives from an original data is provided wherein the original data and variants of the original data are identified.

Abstract: A process for preparing bimodal molecular weight distribution copolymers of ethylene with alpha-olefins having 3 to 20 carbon atoms, said copolymers having: (a) a comonomer distribution wherein the comonomer level at the mid-position of the low molecular weight component is <3 times the level at the mid-position of the high molecular weight component, and (b) a total average comonomer content in the range 0.5-20 short chain branches (SCB)/1000 C atoms characterised in that said process is carried out in the presence of a supported multisite catalyst. The multisite catalyst comprises a metallocene complex and a Ziegler catalyst. The metallocene complex for example is bis(pentamethylcyclopentadienyl) zirconium dichloride.

Abstract: Catalyst composition for use in the polymerization of olefins comprise neutral metal complexes together with activators comprising non-aromatic boron compounds. Suitable activators are triisobutylboron together with trialkylaluminium compounds. Preferred complexes are metallocenes. The use of such activating systems obviates the need for expensive aluminoxanes or aromatic fluorine containing compounds.

Abstract: A cylindrical test object for use in calibrating an ultrasonic bone analyzer has opposing ends that each contain a transducer seat optimized to allow intimate acoustic contact in spite of mechanical errors such as might be encountered in a scanning system. The test object is made of material having known ultrasonic characteristics. When opposing transducers are placed in the test object transducer seats, the test object is lifted off the holder and is free to rotate and translate over sufficient range to compensate for variances in the relative positions of the transducers. The shapes of the transducer ends and transducer seats are chosen to allow intimate acoustic contact in spite of any such translation or rotation. The test object may be a solid or a liquid encased in a solid.
