Abstract: Method and device for indicating sub-band configuration, and method and device for accessing sub-band are provided. The method for indicating sub-band configuration includes: configuring a broadcast channel in a basic sub-band which is configured with a synchronization signal; and indicating sub-band configuration of at least one non-basic sub-band directly or indirectly through a master information block carried by the broadcast channel, wherein the sub-band configuration of the non-basic sub-band is used for user equipment accessing the non-basic sub-band, and comprises a sub-carrier spacing, a Cyclic Prefix (CP) length and a frequency position. UE may access different sub-bands efficiently with relatively high flexibility and relatively few signaling overhead.

Abstract: Disclosed is a membership analyzing method, including: obtaining data information of all members of a target group; classifying members with same first type information into a data set based on predetermined keywords; obtaining the type of first type information and data sets on condition that all members have been successfully classified into a corresponding data set, otherwise, if there is any remaining member failed to be classified into any data set, inputting data information of the remaining member into a predetermined classification model, to obtain the type of first type information and a data set of each remaining member; determining a tree structure of data sets based on the type of the first type information, and producing a graph for the tree structure; setting a same identification for the nodes of the same data set, and displaying second type information of each member in a display area.

Abstract: Disclosed is an oral sustained-release composition for an insoluble drug, which is especially suitable for a low-dose insoluble drug, the oral sustained-release composition comprises a sustained-release granule part and a gel skeleton part, the sustained-release granule part comprises the insoluble drug, an enteric material, and a strong liquid sorbent, and the gel skeleton part comprises a hydrophilic gel skeleton material; and the sustained-release granules are obtained by preparing the insoluble drug and the enteric material into a suspension and then spraying the suspension onto the strong liquid sorbent, the sustained-release granules are wrapped by the gel skeleton to form a multiple sustained-release system technology, which prolongs a release time, and has a simple preparation process, high efficiency, uniform drug mixing, and less content loss.

Abstract: A MOS transistor (60, 62) is provided. The structure of the transistor (60, 62) includes: a semiconductor substrate (10), a channel area (20, 24), source/drain regions (22, 26), a gate (30, 32), a gate insulating layer (11), a shallow trench isolation region (12), a passive layer (50, 52), and holes (40, 42) formed with a certain distance to the gate insulating layer (11). Wherein both the shapes of the holes (40, 42) and the Young's modulus' difference between the material in the holes (40, 42) and that around the holes (40, 42) contribute to the stress concentration effect, thus the stress in the channel area (20, 24) is enhanced. The structure of the transistor (60, 62) can greatly reduce the stress attenuation during the transmission from stress resource to the sensitive region, and concentrate the stress in the sensitive region. The structure can be involved in large size device, especially.
