IPC: B62B1/10
Filed: 2008-09-26
Abstract: A recycle container is adapted for use with a refuse container that has wheels and a lift bar to be engaged by a hydraulic lift unit of a refuse collection vehicle. An engagement flange extends outwardly from a rear wall of the recycle container at a height that enables a hook portion of the flange to engage the lift bar of the refuse container when the containers are supported on level ground. Engagement of the hook portion of the flange on the lift bar enables the recycle container to be joined to the refuse container to facilitate movement of the recycle container and refuse container together. Once the flange is engaged on the lift bar, the refuse container is tilted backward about its wheels and the two containers can be transported together to a curbside location, and detached from each other to await pick-up by collection vehicles.

Title: Nucleotide sequences encoding enzymes in biosynthesis of dihydroartemisinic acid
Inventor: REED DARWIN W
IPC: C12P7/24
Filed: 2007-04-04
Abstract: Isolated nucleic acid molecules cloned from Artemisia annua encode artemisinic aldehyde double bond reductase and artemisinic/dihydroartemisinic aldehyde dehydrogenase. Artemisinic aldehyde double bond reductase enzymatically reduces artemisinic aldehyde to dihydroartemisinic aldehyde. Artemisinic/dihydroartemisinic aldehyde dehydrogenase enzymatically oxidizes dihydroartemisinic aldehyde to dihydroartemisinic acid and artemisinic aldehyde to artemisinic acid. The nucleic acid molecules, and the enzymes encoded thereby, may be used in processes to produce dihydroartemsinic aldehyde, dihydroartemisinic acid or artemisinic acid in a host cell. Dihydroartemisinic acid is a late precursor to the antimalarial compound artemisinin.

Abstract: A self-adjuvanting immunogenic composition comprising multiple immunogens, each immunogen comprising a lipopeptide cap, a universal T helper sequence and an immunodominant HIV-I Tat B cell epitope. The immunogen also comprises one or more linker sequences and/or polar charged amino acid sequences. The HIV-I Tat B cell epitope of each immunogen has an amino acid sequence of V-D-P-Xaa7-L-Xaa9-P-W-Xaal2-Xaal3- Xaal4-Xaal5-Xaal6-amide SEQ ID NO: 1, in which the amino acid positions at Xaa7, Xaa9 and Xaal2 are selected from specific amino acid residues choices and in which the amino acid positions at Xaal3-Xaal6 may be absent or specific amino acid residue choices. The lipopeptide is a dipalmitoyl-S-glyceryl-cysteine or a tripalmitoyl-S-glyceryl cysteine or N-acetyl (dipalmitoyl-S-glyceryl cysteine), each with an optional neutral amino acid linker. Optional polar sequences of at least four charged polar amino acids enhance solubility of the immunogen and are located at the carboxy terminal end of the lipopeptide cap, optionally flanked by neutral linker amino acids, or elsewhere in the immunogen. In the composition, each immunogen differs from another immunogen by an amino acid variation at amino acid position Xaa7, Xaa9 or Xaal2 of the immunodominant HIV-I Tat epitope. Such compositions can induce anti-HFV-l Tat antibodies with geometric mean titers of greater than 1,000,000 on multiple HIV-I Tat variants, when employed to immunize a subject, without any extrinsic adjuvant.

Title: Graphics processing unit with shared arithmetic logic unit
Inventor: DU YUN
IPC: G06T15/00
Filed: 2007-10-15
Abstract: This disclosure describes a graphics processing unit (GPU) pipeline that uses one or more shared arithmetic logic units (ALUs). In order to facilitate such sharing of ALUs, the stages of the disclosed GPU pipeline may be rearranged relative to conventional GPU pipelines. In addition, by rearranging the stages of the GPU pipeline, efficiencies may be achieved in the image processing. Unlike conventional GPU pipelines, for example, an attribute gradient setup stage can be located much later in the pipeline, and the attribute interpolator stage may immediately follow the attribute gradient setup stage. This allows sharing of an ALU by the attribute gradient setup and attribute interpolator stages. Several other techniques and features for the GPU pipeline are also described, which may improve performance and possibly achieve additional processing efficiencies.
