摘要： The invention discloses a method for completely dissolving and rapidly hydrolyzing cellulose, and uses thereof. Cellulose is placed in an acidic aqueous solution with a [H+] concentration of 10−7˜1 M or an alkaline aqueous solution with a [OH−] concentration of 10−7˜1 M as sample A, wherein the volume ratio of solid to liquid is (0.003˜1.05):1. The acidic aqueous solution with a [H+] concentration of 10−7˜1 M or the alkaline aqueous solution with a [OH−] concentration of 10−7˜1 M is heated up to 261˜352 as sample B. Sample A and sample B obtained from step 1 and step 2 are mixed in a reactor to a concentration of cellulose of 0.1%˜35%, the concentration of the mixed solution is adjusted to an acidity of 10−7˜1 M [H+] or an alkalinity of 10−7˜1 M [OH−], and a water density of 587˜997 kg/m3, pressure is set at 6˜584 MPa. The mixture is rapidly heated up to 261˜352 at heating rate of 7.8˜14.8 /s, and then cellulose is dissolved completely in 0.8˜2 sec and hydrolyzed in 5 sec. Using this technique, it is the first time for achieving complete dissolution and rapid hydrolysis of cellulose at a lower temperature, which not only dramatically reduces the cost of hydrolysis but also improves the safety of production and extends the service life of equipment, thus possessing a good application prospect.

摘要： Systems and methods of operating a memory controller may provide for receiving a write request from a motion compensation module, wherein the write request includes video data. A compression of the video data may be conducted to obtain compressed data, wherein the compression of the video data is transparent to the motion compensation module. In addition, the compressed data can be stored to one or more memory chips. Moreover, a read request may be received, wherein stored data is retrieved from at least one of the one or more memory chips in response to the request. Additionally, a decompression of the stored data may be conducted to obtain decompressed data.

摘要： Domain-based cache management methods and systems, including domain event based priority demotion (“EPD”). In EPD, priorities of cached data blocks are demoted upon one or more domain events, such as upon encoding of one or more macroblocks of a video frame. New data blocks may be written over lowest priority cached data blocks. New data blocks may initially be assigned a highest priority. Alternatively, or additionally, one or more new data blocks may initially be assigned one of a plurality of higher priorities based on domain-based information, such as a relative position of a requested data block within a video frame, and/or a relative direction associated with a requested data block. Domain-based cache management may be implemented with one or more other cache management techniques, such as least recently used techniques. Domain-based cache management may be implemented in associative caches, including set associative caches and fully associative caches, and may be implemented with indirect indexing.
