Abstract: A cerasome delivery system for targeting activated cd44 molecule, a preparation method and use thereof: a surface of a cerasome is partially modified by a targeting ligand, the targeting ligand being a ligand which may specifically bind to an activated cd44 molecule. The cerasome delivery system may be used for the diagnosis, prevention and treatment of vulnerable plaque or diseases associated with vulnerable plaque.

Abstract: A technique for improving performance of a cache is provided. The technique involves maintaining indicators of whether cache entries are dirty in a random access memory (“RAM”) that has a lower latency to a cache controller than the cache memory that stores the cache entries. When a request to invalidate one or more cache entries is received by the cache controller, the cache controller checks the RAM to determine whether any cache entries are dirty and thus should be written out to a backing store. Using the RAM removes the need to check the actual cache memory for whether cache entries are dirty, which reduces the latency associated with performing such checks and thus with performing cache invalidations.

Abstract: A technique for scheduling processing tasks having different latencies is provided. The technique involves identifying one or more available requests in a request queue, where each request queue corresponds to a different latency. A request arbiter examines a shift register to determine whether there is an available slot for the one or more requests. A slot is available for a request if there is a slot that is a number of slots from the end of the shift register equal to the number of cycles the request takes to complete processing in a corresponding processing pipeline. If a slot is available, the request is scheduled for execution and the slot is marked as being occupied. If a slot is not available, the request is not scheduled for execution on the current cycle. On transitioning to a new cycle, the shift register is shifted towards its end and the technique repeats.

Abstract: A spectrometry system may include an etalon array having a first etalon and a second etalon. The first etalon may be configured to process light to at least generate a first transmission pattern. The first transmission pattern may have at least a first transmission peak corresponding to a first wavelength in an original spectrum of the light. The second etalon may be configured to process the light to at least generate a second transmission pattern. The second transmission pattern may have at least a second transmission peak corresponding to a second wavelength in the original spectrum of the light. The first etalon may have a different thickness than the second etalon in order for the first transmission pattern to have at least one transmission peak that is at a different wavelength than the second transmission pattern. The first transmission pattern and the second transmission pattern may enable a reconstruction the original spectrum of the light.

Abstract: A technique for improving performance of a data compression system is provided. The technique is applicable to compressed data sets that include compression blocks. Each compression block may be either compressed or uncompressed. Metadata indicating whether compression blocks are actually compressed or not is stored. If compression blocks are not compressed, then a read-decompress-modify-compress-write pipeline is bypassed. Instead, a compression unit writes the data specified by the partial request into the compression block, without reading, decompressing, modifying, recompressing, and writing the data, resulting in a much faster operation.

Abstract: A technique for prefetching data for a cache is provided. The technique includes detecting access to a data block. In response to the detection, a prefetch block generates proposed blocks for prefetch. The prefetch block also examines prefetch tracking data to determine whether a prefetch group including the proposed blocks is marked as already having been prefetched. If the group has been marked as already having been prefetched, then then prefetch block does not prefetch that data, thereby avoiding traffic between the prefetch block and the cache memory. Using this technique, unnecessary requests to prefetch data into the cache memory are avoided.

Abstract: The application discloses an improved wheel pretreatment rack. The wheel pretreatment rack includes a hook, tripods, positioning slide blocks, positioning holes, a main rod, bearing rods, braces and positioning clamping jaws. Compared with the traditional wheel pretreatment rack, the improved wheel pretreatment rack in use has the advantages that the requirement of wheels having different sizes for the pretreatment rack is met by adjusting the positions of the bearing rods up and down, and the problems of drop, scratch and the like in the cleaning pretreatment process of the wheel may be effectively prevented by a wheel three-point-fixing mode.

The detector may be configured to determine a first intensity of a first light emitted by the object in response to the first illumination pattern and a second intensity of a second light emitted by the object in response to the second illumination pattern. The reconstruction engine may be configured to generate an image of the object based at least on the first intensity, the first illumination pattern, the second intensity, and the second illumination pattern.

Abstract: A system and method for maintaining information of pending operations are described. A buffer uses multiple linked lists implementing a single logical queue for a single requestor. The buffer maintains multiple head pointers and multiple tail pointers for the single requestor. Data entries of the single logical queue are stored in an alternating pattern among the multiple linked lists. During the allocation of buffer entries, the tail pointers are selected in the same alternating manner, and during the deallocation of buffer entries, the multiple head pointers are selected in the same manner.

The strain was constructed as follows: heterologously expressing pyrimidine nucleoside operon sequence pyrBCAKDFE (SEQ ID NO:1) on the genome of E coli prompted by strong promoter Ptrc to reconstruct the pathway of uridine synthesis; overexpressing the autologous prsA gene coding PRPP synthase by integration of another copy of prsA gene promoted by strong promoter Ptrc on the genome; deficiency of uridine kinase, uridine phosphorylase, ribonucleoside hydrolase, homoserine dehydrogenase I and ornithine carbamoyltransferase.
