Abstract: The present disclosure generally relates to a personalized cancer vaccine having attenuated cancer cells transfected with at least one expression construct. The expression construct is capable of secretory expression of an antigenic polypeptide that could be derived from a protein from a virus. The personalized tumor vaccine, when administered to a subject in need thereof, is effective to activate an immune response.

Abstract: A battery positive electrode material including lithium ferromanganese phosphate particles and active particles dispersed in voids between the lithium ferromanganese phosphate particles. The active particles include one or more of lithium nickel cobalt manganate particles, lithium nickel cobalt aluminate particles, lithium-rich manganese-based material particles, lithium cobaltate particles, spinel lithium manganate LiMn2O4 particles and layered lithium manganate LiMnO2 particles. The ratio of the median particle diameter of lithium ferromanganese phosphate to that of the active particles is between 3 and 8. In the battery positive electrode material, the content of percentage by weight of the lithium ferromanganese phosphate is between 70% and 90%, and the content of percentage by weight of the active particles is between 10% and 30%.

Abstract: A liquid storage and controlled-release device and a biological detection chip. The liquid storage and controlled-release device comprises a liquid storage capsule with a liquid storage body which is deformable under a pressure, and a sealing layer for sealing the liquid storage body. A support platform is provided right below the liquid storage capsule and tightly connected with the liquid storage capsule, wherein, a directional release chamber is provided at the middle of the support platform, and the directional release chamber is provided with a guiding chamber for collecting the liquid and a sharp edge for inducing break. Compared with the conventional technology, the opening for liquid release is at the end far away from the rotation center, so that the liquid can be released completely by the centrifugal force, ensuring the quantitative release of stored liquid and reducing the influence on the accuracy of the subsequent detection.

Abstract: The present invention discloses a system and a method for resource access control. In the system, a resource access control function entity comprises path selection function means, which is configured to set a QoS policy and select a path meeting the QoS requirement for a service flow based on set QoS policy. In the present invention, by adding the path selection function means and selecting the path using the path selection function means, the x-RACF has the QoS policy based function of path selection and resource control for the service flow accessing to an access network, and thus the QoS guarantee capability of the NGN service is strengthened.
