Abstract: A method for detecting SNP sites of a donor-derived sample and a recipient-derived sample, a method for detecting the presence or proportion of a donor in a receptor sample, and a kit for implementing the methods.

Abstract: A semiconductor structure includes a substrate, a first electrode plate over the substrate, a second electrode plate over the first electrode plate, and a sidewall structure. The sidewall structure is attached to a side of the second electrode plate. A dielectric constant of the sidewall structure decreases in a direction away from the second electrode plate.

Abstract: An exception prompting method at a communication platform having one or more processors and memory storing programs executed by the one or more processors is disclosed. The method includes configuring a user security interface; receiving a monitoring request on a target account from a user logging in to a client terminal; forwarding the monitoring request on the target account to a security platform through a service platform; receiving an exception prompt indicating an unusual activity of the target account from the security platform; generating an alarm notification of the target account based on the exception prompt; and forwarding the alarm notification of the target account to the client terminal.
