    摘要： Various examples are provided for photoacoustic image reconstruction and processing utilizing a backprojection approach. In one example, among others, a method for producing an image with a photoacoustic imaging system includes scanning an object with a plurality of light beams, detecting a plurality of acoustic signals produced by the light beams, and generating a reconstructed image from the plurality of acoustic signals by filtered backprojection (FBP) that utilizes a weighted ramp filter. In another example, a system includes a plurality of acoustic detector units and a processing unit. The acoustic detector units can receive an acoustic wave and convert it to time dependent electrical signals. The processing unit can reconstruct an image of the subject from the time-dependent electrical signals by FBP that utilizes a weighted ramp filter. In another example, non-transitory computer readable medium stores a program that can cause a processing unit to reconstruct an image.

    摘要： Methods for clustering of multi-dimensional data allow unsupervised grouping of multi-dimensional data points into clusters having like characteristics. The methods may be usefully applied to extracellular action potentials (neuronal spikes) measured from the brain, whereby spike data may be grouped in accordance with dimensions such as spike period, spike shape, etc., to assist in identification and location of individual neurons and/or regions of the brain.

    摘要： A method for managing blocks in a flash memory is provided, which includes dynamic and static block managing methods. In the dynamic block managing method, a blank block is selected as a swap block for write operation. During each write operation, new data and/or original data in an object block to be operated are written into the swap block, and the object block is erased. Then, a logical address of the object block is changed to be a logical address of the swap block, so that the object block served as the swap block for a next write operation. In the static block managing method, a variable seed parameter is set. Different values of the seed parameter are each associated with a logical address of a respective flash memory block. When the value of the seed parameter varies, data in the flash memory block and the swap block associated to the value of the seed parameter are exchanged, so that the flash memory block associated to the value of the seed parameter becomes the swap block for the next write operation.

    摘要： The present invention discloses a method for indicating a modulation mode in HSDPA, comprising the following steps: a NodeB receiving capability information reported by a terminal, if determining that the terminal supports 64QAM modulation mode, determining a transmission block size, a modulation mode and code channel resource to be indicated based on an capability constraint condition and the capability information, and if the determined modulation mode is the same as a basic modulation mode satisfying requirement of the transmission block size, setting modulation mode information of a HS-SCCH as 0, otherwise setting the modulation mode information of the HS-SCCH as 1, and then sending the HS-SCCH to the terminal. Application of the present invention is compatible with a UE device which supports or does not support 64QAM high order modulation, without changing the current frame structure of the HS-SCCH, thereby achieving functional support of the 64QAM modulation mode.
