Abstract: A side sliding door of a railway vehicle comprises a door body (100), and a driving device for the opening and closing of a doorway. An outer surface of the door body (100) is flush with an outer surface of the vehicle body when the door body (100) is closed. A movement track of the door body is arranged as an arc-plus-linear reciprocating motion. The outer surface of the door body is flush with the outer surface of the vehicle body when the door body is closed, so that there exists no height difference between the vehicle body and a doorway of the side sliding door. Snow accumulation at doorway under an extreme cold working condition is avoided, and then the risk of a door body being frozen is reduced.

Abstract: Apparatus and associated systems, methods, and computer program products relate to displaying the most relevant information in a document at or near the top of a page of displayed information. The most relevant information may be determined to be relevant with respect to a set of search query terms, such as those that may be entered into a search engine, for example. In some embodiments, a selected document of interest may be formatted (i.e., transcoded) for display on a small display area, and the transcoding may be arranged to produce a first displayed page or sub-page (if the document is divided among more than one sub-page) that begins with the most relevant information in the document. By formatting transcoded pages in this manner, the most relevant information may be displayed first for immediate viewing by the user.
