The method includes controlling a bottom modal view to be displayed on a current user interface, in response to receiving a first instruction configured for indicating a state in which first information is to be received, the bottom modal view being a floating layer page displayed on the current user interface, having an area less than that of the current user interface, and comprising a first input widget; and controlling the first information to be input based on an input signal in response to the first input widget being triggered.

Abstract: According to examples, an apparatus may include a hardware processor that may determine throughputs at which servers communicated over a network through execution of throughput tests with the servers. The hardware processor may also identify which of the servers communicated over the network at a throughput that meets or exceeds a predefined throughput and may send identifiers of the servers to a test service provider. The test service provider may, in response to receipt of a request for execution of a throughput test that meets or exceeds the predefined throughput, at least one of output an identifier of at least one of the identified servers to execute the throughput test and select one of the identified servers to execute the throughput test. The hardware processor may also cause a test instrument to execute a throughput test with the identified server at or above the predefined throughput.

Abstract: The present disclosure discloses a milk powder containing maltopentaose trehalose instead of maltodextrin and a preparation method thereof, and belongs to the field of processing of dairy products. In the present disclosure, a formula milk powder containing maltopentaose trehalose instead of maltodextrin includes the following raw materials in parts by mass: 85-90 parts of fresh milk, 1-2 parts of maltopentaose trehalose, 5-10 parts of vegetable oil, 1-2 parts of a desalted whey powder, 1.5-3 parts of a concentrated whey protein powder, 0.5-0.8 parts of lactose, 0.05-0.1 parts of a multivitamin, and 0.05-0.1 parts of a complex mineral. Differences in physical and chemical properties of products due to a nonuniform polymerization degree of maltodextrin are reduced, and the problem that a Maillard reaction is likely to be induced when the maltodextrin is mixed with an amino acid or protein is solved.

Abstract: According to a prior art, components having a crack are repaired, wherein the thus produced elongated recess is filled with a solder material which nevertheless produces a weak point. The inventive component, in addition to the material filled recess, comprises an additional material filled recess which extends transversely to the longitudinal direction of the cavity.

Abstract: In an ion cyclotron resonance mass spectrometer, ion cyclotron resonance signals at higher harmonics of cyclotron frequency are employed to increase the resolution of ICR mass spectrometer without increasing the magnetic field. The detection electrodes consist of M (where M is an integer) identical electrodes arranged in M-fold symmetry about the axis of the coherent cyclotron motion of the observed ions. In an ion cyclotron having four points of voltage in space, the cyclotron electrodes are set up in clockwise symmetric fashion. To increase the resolution in signal detection resulting from the potential induced by ions moving in orbits in the specrometer, the first and third voltages are added and the second and fourth voltages are subtracted from the sum of the first and third voltages.
