Abstract: An engine includes a cylinder head and a cylinder block. The cylinder head has a first water jacket passage, an exhaust passage and a second water jacket passage. The exhaust passage is located between the first water jacket passage and the second water jacket passage. The first water jacket passage and the second water jacket passage are disposed close to the exhaust passage. The first water jacket passage is in communication with the second water jacket passage. The second water jacket passage is in communication with the cylinder block. The second water jacket passage has a water inlet passage.

Abstract: Disclosed are a low-cost high-efficiency drip irrigation system for a cotton field and a use method thereof. The drip irrigation system for a cotton field includes a filtering device and a water supply device; wherein the filtering device adopts different types of single filtering devices or combined filtering devices according to different water source types; the water supply device includes multiple stages of main pipes, submain pipes and laterals; the laterals (a drip irrigation tape with labyrinth on one side or a drip irrigation tape inlaid with emitters inside) are laid on the surface of the ground and located below a mulch film. The drip irrigation system adopts the design of large flow (1.5-3.4 L/h), slightly larger pipe diameter (>75 mm), low water pressure (operating pressure of drip irrigation tape being 0.03-0.07 MPa) and suitable drip irrigation uniformity (80%-90%).

Abstract: Embodiments disclosed herein provide compositions, methods, and uses for respiratory syncytial viruses (RSV) and immunogenic compositions thereof. Certain embodiments provide RSV having a mutated NS1 protein, where the mutation causes the uncoupling of the NS1 protein's replication and type I interferon (IFN) antagonist functions. In some embodiments, this uncoupling can produce virions capable of inducing a strong, long-lasting innate immune response while maintaining its ability to replicate in vitro. Also provided are methods for amplifying RSV in host cells, wherein amplified RSV has mutated NS1 protein in which the protein's replication and IFN antagonistic functions are uncoupled. In certain embodiments, the amplified RSV having mutated NS1 protein is formulated into immunogenic compositions, including vaccines. Other embodiments provide methods for inducing an effective immune response against RSV infection in a subject.

Abstract: The present invention relates to apparatuses and methods for exchange of signaling information in coordinated multi-point (CoMP). Partial embodiments of the present invention provide a method for exchange of signaling information in CoMP, where a first transmission point and a second transmission point provide CoMP for at least one user equipment (UE). The method includes: the first transmission point determining resource allocation for at least one of the first transmission point and the second transmission point, that is, the first transmission point notifying the second transmission point of the determined resource allocation. The resource allocation includes at least one of beamforming, power, and UE scheduling of the corresponding transmission point. The present invention can support CoMP under practical network conditions more effectively.
