Abstract:
Executing a map reduce sequence may comprise executing all jobs in the sequence by a collection of a plurality of processes with each process running one or more mappers, combiners, partitioners and reducers for each job, and transparently sharing heap state between the jobs to improve metrics associated with the job. Processes may communicate among themselves to coordinate completion of map, shuffle and reduce phases, and completion of said all jobs in the sequence.
Abstract:
An incandescent lamp is disclosed, incorporating a special optical coating system that enables the lamp to provide an improved luminous efficacy. In one form, the optical coating system includes a plurality of dielectric layers having prescribed refractive indices and prescribed thicknesses, which are selected such that the optical coating provides a prescribed transmittance/reflectance spectrum having an average reflectance greater than 90% across an infrared wavelength range of 740 to 2000 nm and further having an average transmittance of less than 90% across a visible wavelength range of 400 to 700 nm. In another form, the optical coating system includes two distinct coatings: (1) a first coating including a plurality of dielectric layers having prescribed refractive indices and prescribed thicknesses, which are selected such that the first coating provides a prescribed transmittance/reflectance spectrum, and (2) a second coating including a transparent electrically conductive material configured such that the second coating provides a prescribed transmittance/reflectance spectrum. The invention also is embodied in a lighting fixture incorporating an optical coating as described above, located either on the envelope of the incandescent lamp, itself, or on another substrate of the fixture, separate and apart from the lamp, e.g., a fixed transparent envelope surrounding the incandescent lamp.
Abstract:
The subject invention provides purified polypeptides encoded by naturally-occurring wild-type platelet glycoprotein Ib alpha having a mutation which renders the polypeptide more reactive with yon Willebrand factor. Preferably, the mutation is in the hinge region of GP Ib.alpha., such as the substitution of valine for glycine at residue 233. These mutations alter the three-dimensional structure of the mutant polypeptide from a beta bend conformation to an alpha helix formation, and also create an amphipathic region within the mutant polypeptide. DNA encoding the mutant polypeptides, as well as expression systems for the production of the mutant polypeptides, are also provided. Methods and compositions using the mutant polypeptides and DNA oligomers complementary to the mutant polypeptides are further provided.

Abstract:
A ballistic composite comprises multiple layers of a fabric having unidirectional ballistic resistant yarns in at least two layers and a resin layer between each pair of such multiple layers adhered to the ballistic resistant yarns but not encapsulation the same and not penetrating the layer of fabric. The ballistic yarn layers are at 90°±5° with respect to each other and the ballistic resistant yarns are stabilized by being woven in a second fabric. The second fabric is formed of yarns having a substantially lower tenacity and tensile modulus than the ballistic resistant yarn. The ballistic resistant yarns have a tenacity of at least about 15 grams per denier and a modulus of at least about 40 grams per denier. The resin in the resin layer has a modulus of at least about 7000 psi.
Abstract:
A method is disclosed for controlling a lighting fixture of a kind having individually colored light sources, e.g., LEDs, that emit light having a distinct luminous flux spectrum that varies in its initial spectral composition, that varies with temperature, and that degrades over time. The method controls such fixture so that it projects light having a predetermined desired flux spectrum despite variations in initial spectral characteristics, despite variations in temperature, and despite flux degradations over time.
Abstract:
The subject invention provides purified polypeptides encoded by naturally-occurring wild-type platelet glycoprotein Ib alpha having a mutation which renders the polypeptide less reactive with von Willebrand factor. Preferably, the mutation is in the leucine rich region of GPIb.alpha., such as the substitution of phenylalanine for leucine at residue 57. DNA encoding the mutant polypeptides, as well as expression systems for the production of the mutant polypeptides, are also provided. Methods and compositions using the mutant polypeptides and DNA oligomers complementary to the mutant polypeptides are further provided.
