Also described are pharmaceutical formulations comprising the compounds of Formula A-a or their salts, and methods of treating neuropathic pain disorders using the same.

Abstract: In a device for producing quantitative-diameter spray droplets of pesticide, a driving motor is controlled by a control center, the driving motor drives a lead screw, the lead screw drives a sliding device to achieve a designated accurate position on a guide track, and a piston moves slowly along with the sliding device to extrude chemicals in a droplet generator quantitatively, the chemicals extruded by the piston through the motion in a droplet cavity forms small single droplets through a guide pipe, the droplets with specific particle size are further generated by precisely controlling the extrusion amount of the chemicals, so that the device can be widely used for studies about diffusion of the droplets evaporation property of the single droplets and the like tested by water-sensitive paper, as well as tests of the properties of the pesticide, and further has broad application prospects.

Abstract: The present application relates to: (a) compounds of Formula (I): and salts thereof, wherein Y and Z are as defined in the specification; (b) compositions comprising such compounds and salts; and (c) methods of use of such compounds, salts, and compositions, particularly use for the treatment and prevention of diseases such as those associated with oxidative stress and inflammation.

Abstract: A method of downscale decoding MPEG-2 video includes an Inverse Discrete Cosine Transformation (DCT) procedure for performing a ½ horizontal downscaling to convert DCT coefficients in a 8×8 array block of the video into a 4×8 array intra-block and performing a ½ vertical downscaling to convert the intra-block into an intra-coded picture having ¼ resolution of the original; and a downscaling motion compensation procedure for performing a motion compensation to the current intra-block to obtain a predictive block having ½ horizontal size of the original, adding the predictive block with a residual block produced by the same method applied to the intra-blocks to obtain a 4×8 array inter-block, and performing a ½ vertical downscaling to the inter-block for outputting a predictive-coded picture and a bidirectional predictive-coded picture having ¼ resolution of the original, so as to simplify the complexity of the decoding computation and enhance the decoding speed.

Abstract: In an interactive display system, a transmitter is provided for transmitting a periodic signal to a plurality of receivers through the air. One or more phase differences are measured between the receiving at pairs of receivers. These phase differences control the coordinates of a locator on a display screen. Separate measured phase differences control the positions along different coordinate axes independently.
