Abstract: A method for making a toothpaste enabling enamel restoration proposes to encapsulate soluble calcium and phosphate salts within corresponding internal water phases in respective water-in-oil-in-water emulsions. In this way, the soluble calcium and phosphate salts can be present stably in the toothpaste over a long period of time without causing precipitation of calcium phosphate. When the toothpaste of the present disclosure is used in brushing teeth, the water-in-oil-in-water emulsions are ruptured under the effect of friction and pressing, releasing the soluble calcium and/or phosphate salts encapsulated within the corresponding internal water phases. As a result, the liquid in the user's oral cavity will contain high concentrations of calcium and phosphate ions, which can enhance the rate of remineralization of enamel and/or dentin exposed to the oral cavity.

Abstract: A method for making a composition for enamel regeneration proposes to encapsulate soluble calcium and phosphate salts within corresponding internal water phases in respective water-in-oil-in-water emulsions stabilized by solid particles, and add them to a toothpaste, enamel restoring gel or mouth wash base. In this way, the soluble calcium and phosphate salts can be present stably in the toothpaste, enamel restoring gel or mouth wash over a long period of time. When the toothpaste, enamel restoring gel or mouth wash of the present disclosure is used in oral cavity, the water-in-oil-in-water emulsions rapture under the effect of friction and pressing, releasing the soluble calcium and phosphate salts encapsulated within the corresponding internal water phases. As a result, the liquid in the user's oral cavity will contain high concentrations of calcium and phosphate ions, which can enhance the rate of enamel remineralization.

Abstract: Methods and apparatuses are provided in which at least one parameter associated with a sidelink transmission is received from a base station. It is identified whether an uplink transmission is scheduled in a transmission time interval (TTI) in which a sidelink transmission to a second terminal is scheduled.

The sidelink transmission is transmitted based on a smaller transmission power value from two transmission power values.

Abstract: A user equipment (LTE) for operation in a fifth-generation system (5GS) is configured to decode configuration information for a first hybrid-automatic repeat request (HARQ) acknowledgement (ACK) (HARQ-ACK) codebook for first priority HARQ-ACK bits and for a second HARQ-ACK codebook for second priority HARQ-ACK bits. The configuration information may indicate a physical uplink control channel (PUCCH) resource for the first HARQ-ACK codebook and a PUCCH resource for the second HARQ-ACK codebook. The UE may multiplex the first priority HARQ-ACK bits and the second priority HARQ-ACK bits in a PUCCH transmission when the PUCCH resources for the first and the second HARQ-ACK codebooks overlap. The LTE may use the PUCCH resource for the higher priority HARQ-ACK bits to multiplex the first priority HARQ-ACK bits and the second priority HARQ-ACK bits.
