Abstract: A method and system transcodes an input video to a lower spatial resolution. The input video is first decoded into pictures. Each picture includes a set of macroblocks. Each picture sub-sampled to a downscaled picture having a lower spatial resolution. A quantization scale is selected for each macroblock in the downscaled picture. A set of motion vectors is generated for each macroblock in the downscaled picture. A multiplier value based on the quantization scale is determined for each macroblock in the downscaled picture. One of a plurality of encoding modes is selected for each macroblock in the downscaled picture according to the quantization scale, the motion vectors, and the multiplier value. Then, each macroblock in each downscaled picture is encoded according to the quantization scale, the selected encoding mode, and the set of motion vectors to produce an output video having a lower spatial resolution that the input video.

Abstract: The present invention provides a method for controlling crown gall disease in plants using an effective quantity of ?-proteobacteria that produces trifolitoxin (TFX). The present invention also provides a biocontrol agent for use in the above method, and a plant coated with the biological control agent. The biocontrol agent is characterized as a biologically pure culture of an ?-proteobacteria strain that produces TFX, or an ?-proteobacteria strain genetically engineered to produce TFX. The ?-proteobacteria strain employed may include any one of the many strains of Agrobacterium capable of producing crown galls, including Agrobacterium vitis and, in particular, A. vitis F2/5. The ?-proteobacteria strain employed may be genetically engineered to produce TFX by introducing a genetic construct into the Agrobacterium so as to cause the Agrobacterium to carry and express the tfx operon from Rhizobium.

Abstract: Provided is a field emission display in which a gate hole having an inclined inner wall and a gate electrode around the gate hole are formed between an anode plate having a phosphor and a cathode plate having a field emitter and a control device for controlling a field emission current, whereby the voltage applied to the gate electrode of the gate plate serves to prohibit an electron emission of the field emitter by the anode voltage, and prevent a local arching by forming a totally uniform potential, so that the life time of the field emission display can be improved, and the gate hole having the inclined inner wall enables a fabrication of a filed emission display panel having a high brightness without an additional focusing grid.

Abstract: A method of delivering intensity modulated radiation therapy (IMRT) is disclosed. An intensity profile for the treatment of a patient is provided which spans a prescribed field width and includes a discrete profile having intensity values at each of a plurality of sample points bounded by the prescribed width. The prescribed width is compared to a maximum field width provided by the radiation treatment system. The intensity profile is split into a plurality of intensity profile portions, each having respective widths less than the maximum width if the prescribed width is greater than the maximum width. The prescribed field is also divided into a plurality of different profile portion split arrangements. A monitor unit (MU) efficiency is calculated for each of the arrangements. One of the arrangements is selected for delivery by the system using a leaf sequencing method.

Abstract: A micro-electromechanical device includes a substrate. A drive circuitry layer is positioned on the substrate. A nozzle chamber wall and a roof wall are positioned on the substrate to define a nozzle chamber above the substrate and a fluid ejection port in the roof wall. A substantially planar deformable fluid ejecting member is interposed between the substrate and the roof wall and is configured to deform cyclically under action of a pulsed electromagnetic field. The drive circuitry is configured to generate said pulsed electromagnetic field so that the fluid ejecting member acts on fluid to eject fluid from the fluid ejection port.

Abstract: An elongated hollow member (160), as shown in FIG. 1, with longitudinally disposed external vane(s) (275A–B) for securing an offshore structure to the seafloor. The external vanes help maintain the heading and bearing of the anchor during the installation process, and may also enhance the pile anchor's holding capacity.
Abstract: Methods and apparatus or generating a radiation pulse sequence are disclosed. One embodiment of the apparatus includes two coupled direct space-to-time pulse generators (DSTPGs) with a channel operation element (COE) in between. The first DSTPG forms multiple spatially separated radiation pulse sequences. The COE operates to modify one or more of the radiation pulse sequences, such as imparting a time delay between them. The modified radiation pulse sequences are then combined by the second DSTPG to form a single output radiation pulse sequence.
Abstract: The present invention provides counter flow cascade separation systems useful to separate solute/solute pairs present in a solvent. The separation systems include a series of interconnected stages with each stage comprising a combination of a diafilter preferentially permeable for one solute and an ultrafilter that accepts a permeate flow from the diafilter. The ultrafilter is permeable to solvent. Solute/solute pairs are preferentially separated by the diafilter into permeate and retentate flows and excess solvent is removed from the permeate flow by the ultrafilter and recycled back into the system. Stages are combined to form a counter flow cascade separation system capable of operation approaching an ideal counter flow cascade.
Abstract: An elongate actuator is anchored at one end to the wafer substrate to be in electrical contact with the drive circuitry layers. A closure member is mounted on an opposite end of the elongate actuator. The actuator is configured to receive an electrical signal from the drive circuitry layer to displace the closure member between a closed position in which the closure member covers the fluid supply opening and ink is inhibited from flowing through the fluid supply channel and an open position. The elongate actuator is shaped so that, in a rest condition, the actuator encloses an arc. The actuator includes a heating portion that is capable of being heated on receipt of the electrical signal to expand.

Abstract: Compositions and methods for addressing oxygen inhibition in free radical polymerization systems and determination of oxygen content in a monomer or oligomer. The compositions used include a singlet oxygen generator and a singlet oxygen trapper. Addition of the generator and trapper resulting in removal of oxygen can occur before polymerization or essentially simultaneously with polymerization. Determination of oxygen content comprises monitoring the concentration changes from the reaction of the singlet oxygen trapper with the oxygen in the system.
