Abstract: The present invention discloses an improved method for magnetic transfection of maize pollen, including: (1) preparing plasmid DNA for transfection; (2) binding MNP nanomagnetic beads to the plasmid DNA at room temperature to form MNP-DNA complex; (3) collecting fresh pollen from maize at full flowering and bringing it rapidly back indoors under ice box storage conditions insulated from water; (4) mixing a maize pollen transformation solution with sieved maize pollen and being subjected to aperture-opening pre-treatment at low temperature; (5) adding the MNP-DNA complex to aperture-opening pre-treatment solution, mixing gently and placing on a low temperature pre-cooled magnetic plate for transfection; (6) after transfection, taking the pollen suspension to field in ice box and pollinating directly on ears of maize.

Abstract: Aspects of the disclosure provide methods and apparatuses for providing application interfaces. For example, a terminal device includes a display screen and processing circuitry. The processing circuitry displays, via the display screen, a fake interface for a specific application in response to a state change of the specific application. The fake interface displays non-privacy content that has no association with the specific application. Then, the processing circuitry detect an operation on the fake interface, and displays, via the display screen, an application interface of the specific application with privacy content when the operation on the fake interface satisfies a pre-defined requirement.

Abstract: An information sending method includes displaying, by a first social client, an expectation message sending control on a user interface. The expectation message sending control corresponds to at least one second social client. The method also includes receiving a trigger signal for the expectation message sending control; and sending an expectation message to a server according to the trigger signal, which includes an identifier of the at least one second social client, to cause the server to forward the expectation message to the at least one second social client. The method also includes, after receiving the expectation message forwarded by the server, displaying, by each second social client, prompt information according to the expectation message, and the prompt information being used to indicate that the first social client is waiting for the second social client to send a social-network message to the first social client.

Abstract: A method, a device, and a system for receiving an emergency event alert are provided, which relate to a field of communication applications. As long as communication between a user terminal and a bearer network is normal, no matter whether the user terminal is watching live television programs, the user terminal can receive the emergency event alert in time. The method is as follows. A receiving unit discovers an emergency event alert service. The receiving unit is attached to the emergency event alert service. The receiving unit receives an emergency event alert message sent by a distributing unit. An emergency event alert receiving unit device includes a discovering and processing module, a service attachment processing module, and a message reception processing module. Through attachment to the emergency event alert service, the user terminal can receive the emergency event alert in time.
