Abstract: The present disclosure provides a cloth attaching device and a cloth attaching method. The cloth attaching device comprises: a cylindrical base, a rubbing roller opposing the cylindrical base and an actuating unit, an annular adhesive layer covering a cylindrical surface of the cylindrical base; a first connecting component holding both ends of the cylindrical base and connecting to the actuating unit; and a second connecting component holding both ends of the robbing roller and connecting to the actuating unit. The actuating unit is configured to control a movement of the first connecting component and the second connecting component so that the rubbing roller and the cylindrical base rotate in sync or not in sync. The present disclosure overcomes defects in which the rubber pad displaces very easily and the aging process is very time consuming, which facilitates to improve fabricating efficiency and quality of the rubbing roller.

Abstract: The present invention provides a liquid crystal display substrate and a preparation method thereof, which belongs to the technical field of liquid crystal display and may solve the problem that vias in the existing liquid crystal display substrate will result in non-uniform thickness of an alignment layer and thus influence the display effect. The liquid crystal display substrate provided by the present invention comprises a plurality of display structures, and an alignment layer located above all the display structures, wherein at least some of the display structures are provided therein with vias, and at least some of the vias are surrounded by baffle walls that are located under the alignment layer.

Abstract: The present invention provides a measuring tool comprising a support portion and a measuring portion, the measuring portion is movably connected to the support portion, the support portion is configured for supporting the measuring portion, the measuring portion is configured for successively measuring at least one gap between a base and a workpiece on the base. The measuring tools, by providing a measuring portion capable of successively measuring at least one gap between the rubbing base and the rubbing roller, avoid frequent replacement of the measuring portion, thereby the measuring efficiency is increased greatly, and the utilization rate of processing equipment is improved.

Abstract: The present invention discloses a media file on-demand method, comprising: the server, upon receiving the media on-demand request from the client, provides the index information in the self-defining media file to the client; the server, upon receiving the playing progress request from said client, according to the requested time in the playing progress request, searches for the starting offset position of the media data corresponding to the requested time in the index information; the server, according to the starting offset position of the media data, reads out the media data corresponding to the requested time in the self-defining media file, and provides the media data to the client.

Abstract: The present invention provides adenoviral vectors comprising cell status-specific transcriptional regulatory elements which confer cell status-specific transcriptional regulation on an adenoviral gene. A “cell status” is generally a reversible physiological and/or environmental state. The invention further provides compositions and host cells comprising the vectors, as well as methods of using the vectors.

Abstract: The invention provides adenoviral vectors (preferably replication competent) comprising both an E3 sequence and at least one adenoviral gene under transcriptional control of a target cell-specific transcriptional response element. These vectors display significantly improved cytotoxicity, which is especially useful in the cancer context, in which selective destruction of target cells is desirable. The invention further provides host cells comprising the vectors. The invention further provides methods of using the adenoviral vectors.

Abstract: Cell specific replication-competent viral vectors comprising a self processing peptide cleavage sequence are provided. The targeted replication-competent viral vectors include two or more co-transcribed genes under transcriptional control of the same heterologous transcriptional regulatory element (TRE), wherein at least a second gene is under translational control of a self processing cleavage sequence or 2A sequence. Exemplary vector constructs may further include an additional proteolytic cleavage site which provides a means to remove the self processing peptide sequence from the viral vector.
