A composition for treating skin pigmentation, a method of forming the composition, and a method of treating skin pigmentation are disclosed. The composition comprises at least one pharmaceutically acceptable additive. The composition further comprises at least one melanin production inhibitor, which may be a depigmentation agent. The melanin production inhibitor is present in an amount effective to inhibit melanin production in human skin cells of a subject that is administered the composition. The melanin production inhibitor is selected from the group consisting of cyclovirobuxine D, lipoic acid, nuciferine, peimisine, oleuropein,extract,(Regel) Maxim extract,etextract,extract,semen extract,extract,semen extract,semen extract,extract,semen extract,semen extract,extract,seed extract,extract,extract,extract,extract, and combinations thereof.

Composition for treating skin pigmentation and related methods

Embodiments of the present invention provide a device and method for communication correction. The device includes a receiving channel and a correction channel, where the receiving channel includes an analog radio-frequency front end, a demodulator, a first analog-to-digital converter, and a first channel correction module that are connected sequentially, and the correction channel includes a frequency converter, a second analog-to-digital converter, and a digital processor that are connected sequentially, where the analog radio-frequency front end is further connected to the frequency converter, and the digital processor is connected to the first channel correction module. With the technical solutions of the present invention, channel correction is performed on the receiving channel by the correction channel, so as to improve the precision of receiving a radio signal.

Device and method for communication correction

A bandwidth configuration method includes: A terminal acquires that a narrow bandwidth mode is used at a network side by a downlink transmission signal and/or an uplink transmission signal; and the terminal configures a receiving bandwidth and/or a transmitting bandwidth, where the receiving bandwidth and/or the transmitting bandwidth corresponds to the narrow bandwidth mode at the network side. The terminal side can acquire whether the network side uses the narrow bandwidth technology, and automatically adjust a bandwidth of a corresponding channel at the terminal side when the network side uses the narrow bandwidth technology, so that intra-system performance loss and inter-system interference that are caused by different bandwidth modes between the terminal side and the network side are avoided, thus improving performance of a communication system.
