Abstract: A transmission method and a communication apparatus provide a source access network device receives first data and a first identifier. The first identifier indicates a last data packet of the first data, and the first data is data in a first periodicity of a periodic service. The source access network device sends a handover command to a terminal device in a first time period. A start moment of the first time period is a moment at which the last data packet is sent, an end moment of the first time period is an end moment of the first periodicity, and the handover command instructs the terminal device to perform a handover to a target access network device. This avoids interruption of sending the first data by the source access network device due to the handover and improves transmission reliability of the periodic service.

Abstract: A Streptococcus suis (S. suis) vaccine is provided. For the S. suis vaccine, an antigen is a protein with an amino acid sequence shown in SEQ ID NO: 2. A preparation method of the S. suis vaccine is provided, including the following steps: mixing a white oil and aluminum stearate to obtain a white oil adjuvant; adding poly sorbate 80 to an aqueous solution of the protein with the amino acid sequence shown in SEQ ID NO: 2, and thoroughly mixing to obtain an antigen solution; and mixing the antigen solution with the white oil adjuvant according to a volume ratio of (0.5-1.5):2, and emulsifying to obtain the S. suis vaccine. An animal immunized with the S. suis vaccine of the present disclosure can effectively resist the attack of S. suis serotype 2, 3, and 31, with a vaccine protection rate as high as 100%.

Abstract: A quantum layout optimization method includes: determining target Hamiltonian parameters of a quantum device; determining an initial quantum layout of the quantum device and initial geometric parameters of the initial quantum layout; determining a target gradient of Hamiltonian parameters of the quantum device to geometric parameters of the initial quantum layout; and adjusting the initial geometric parameters based on the target gradient to have the Hamiltonian parameters of the quantum device be the target Hamiltonian parameters to obtain a target quantum layout.

Abstract: A dispensing system comprises a first dispenser and a second dispenser each including a first end, a second end, a longitudinal axis extending through the first end and the second end, and a set of nozzles arranged about the longitudinal axis. The first dispenser is positioned relative to the second dispenser such that the longitudinal axis of the first dispenser is non-coaxial with the longitudinal axis of the second dispenser. The dispensing system also comprises a substrate chuck configured to hold a substrate and a rotation mechanism configured to rotate the substrate chuck around a rotation axis or configured to rotate the first dispenser and the second dispenser around the rotation axis.

Abstract: A method of cleaning a fluid dispenser for dispensing a material during non-contact maintenance of the fluid dispenser. The fluid dispenser including a plurality of nozzles disposed on a faceplate. The method including applying a suction force onto a surface of the faceplate using a suction apparatus, the suction apparatus being translated from one end of the faceplate to an opposite end of the faceplate such that a portion of nozzles from the plurality of nozzles are exposed to the suction force. The method continues by vibrating a menisci of the portion of nozzles that are exposed to the suction force to remove at least a portion of the material accumulated on the faceplate.

Abstract: An electrowetting system and method for the movement of a droplet across the surface of a substrate, utilizing an applied voltage. The actuation of the droplet is achieved by introducing a diode into the idealized electrical circuit of the electrowetting system. The diode is in parallel with a capacitor (dielectric) and effectively shorts the droplet on the side of a lower potential electrode so that the entire voltage drop is across the dielectric over the higher potential electrode. This difference in potential creates an energy imbalance that is effective in moving the droplet towards the higher potential electrode. If the voltage polarity is reversed, the direction of actuation will also be reversed.
