  • Publication number: 20200281865
    Abstract: The invention discloses a preparation method of pH/reduction responsive polyamino acid zwitterionic nanoparticles, which belongs to the technical field of polymer synthesis and biomedical materials. In the invention aliphatic amines are used to initiate ring-opening polymerization of ?-benzyl-L-glutamate-N-carboxylic anhydride, and the obtained poly(?-benzyl-L-glutamate) reacts with L-lysine to form azwitterionic polymer. The zwitterionic polymer is crosslinked by cysteamine, producing pH/reduction responsive polyamino acid zwitterionic nanoparticles after purification. The nanoparticles are pH responsive and resistant to non-specific protein adsorption. Because cysteamine contains disulfide bonds, the nanoparticles have sensitive reductive responsiveness and can load anticancer drugs for controlled release at the target site of cancer.

    Abstract: Hybrid amphiphilic star copolymer nano micelles are prepared in the invention. Cage shaped octa(?-aminopropyl) silsesquioxanes is selected as the inorganic part, and L-glutamic benzyl ester—five membered ring anhydride is ring-opening polymerized by the initiation of amino groups on the surface of cage shaped octa(?-aminopropyl) silsesquioxanes, producing copolymers with cage shaped octa(?-aminopropyl) silsesquioxanes as nucleus and poly (L-glutamic-benzyl ester) as arms. The copolymers reacts with monomethoxy poly (ethylene glycol) carboxylic acid by condensation. Finally, the benzyl groups in the side chains of poly (L-glutamic acid-benzyl ester) are converted into hydrazine groups by acylhydrazination to obtain hybrid amphiphilic star copolymer nano micelles. The micelles can load doxorubicin, they are safe to human body and have good application prospects.

  • Patent number: 10628279
    Abstract: To manage memory in a multi-processing system, a memory budget is assigned to each of a number of agents within the multi-processing system. A portion of memory is allocated to each the agents within the memory budget. Metrics are collected for each agent during processing of data by the agents; the metrics include an amount of data processed and an amount of memory used for each agent. Memory efficiency is determined for each agent based on the collected metrics and another memory budget is determined based on the memory efficiency. The portion of the memory is reallocated to the agents within the other memory budget in response to data stored in the memory relative to the assigned memory budget meeting a criterion.

  • Publication number: 20190140126
    Abstract: A light reflective film, a processing method and a photovoltaic cell module. The vertex height of a prism and/or the bottom width of the prism change periodically to form a polyhedral structure, and the adjacent faces can present a mirror structure, so that the entire prism can reflect both morning and afternoon sunlight, which leads to improved reflection efficiency throughout the work period. In the prior art, the reflective surface of the straight triangular prism has a constant angle with respect to the axis of the working plane of a photovoltaic cell module, therefore, it only has high reflection efficiency for the sunlight at a certain time; the granular reflective micro-structure, such as a triangular pyramid, can be aligned with the sunlight on two sides thereof to reflect the sunlight in the morning and afternoon, but there are many blank areas between the granules.

  • Publication number: 20190130040
    Abstract: Embodiments described herein provide a solution for optimizing a generating of query search results. A filtering search term (e.g., a search term that is used in a query to perform filtering aggregations of the query search results) is identified. A filtering bitmap that has a plurality of mapped locations corresponding to data values for the filtering search term is created. As a data value in the filtering search term is encountered during a scan of the query search results, the corresponding mapped location is updated. Each mapped location in the filtering bitmap is read to determine whether the value corresponding to the mapped location satisfies the filtering aggregation. The filtering aggregation can then be performed (e.g., prior to any grouping aggregation) by removing any of the query search results determined, based on the filtering bitmap, as having data values for which the filtering aggregation is not satisfied.
