Abstract: The disclosure provides a server cabinet, including: a cabinet frame, first mounting flanges detachably and vertically arranged at two sides of a front end of the cabinet frame, second mounting flanges detachably and vertically arranged at the two sides of the front end of the cabinet frame, first support brackets detachably arranged at the two side walls of the cabinet frame and configured for installing an ODCC server, and second support brackets detachably arranged at the two side walls of the cabinet frame and configured for installing an OCP server; wherein a plurality of first mounting holes configured for being matched with a front end of the ODCC server are formed in the first mounting flanges along a height direction, and a plurality of second mounting holes configured for being matched with a front end of the OCP server are formed in the second mounting flanges along the height direction.

Abstract: An access control method. A BNG CP may receive a first message from first user equipment. The first message is used by the first user equipment to request to access a network, a primary gateway through which the first user equipment accesses the network is a first BNG, and a backup gateway through which the first user equipment accesses the network is a second BNG. After receiving the first message, the BNG CP may determine, from a first network segment, an IP address assigned to the first user equipment, and send the IP address of the first user equipment to the first user equipment. The first network segment is only used to assign an IP address to user equipment that accesses the network by using the first BNG as a primary gateway and the second BNG as a backup gateway.

Abstract: A primer pair for identification of Ommastrephes bartramii in the North Pacific Ocean based on environmental DNA, and a method for identifying Ommastrephes bartramii using the same. The primer pair consists of a forward primer OMBA-F: 5?-CGAAGGTTAATCTGTCTCCATCT-3? (SEQ ID NO: 1), and a reverse primer OMBA-R: 5?-CCCAATTAAAATTTATATACCACCACCT-3? (SEQ ID NO: 2). A DNA molecular marker locus for identifying Ommastrephes bartramii is located at 16S rRNA of Ommastrephes bartramii. The environmental DNA is amplified and sequenced, and if the obtained sequence is completely identical to the sequence of the DNA molecular marker locus, it is indicated that there is Ommastrephes bartramii in the sampling region.

Abstract: Embodiments of the present disclosure provide a routing method and device. The method includes: receiving an access request from a user, wherein the access request points to a page, obtaining user attribute information of the user based on the access request, determining, based on at least a part of the user attribute information and according to a preset rule, a server cluster, wherein the server cluster is configured to provide a service on the page for the user, and routing the access request to the server cluster.

Abstract: A vaginal dilator having side blades or having upper and lower blades including accessorial blades is described. The vaginal dilator includes an upper blade, a pressing member, a lower blade and a handle. The upper and lower blades are connected by a pin. The pressing member is engaged with the handle by a first dilating fixation device. The vaginal dilator having side blades includes an arc-shaped movable locating sleeve rotationally connected with the upper blade. Each end of the sleeve is provided with a mounting base. The mounting base is provided with a joint cavity for receiving a side blade which can be retracted between the upper and lower blades. The back portion of the side blade is provided with a second dilating fixation device engaged with the back end of the upper blade or a locating buckle of the mounting base.

Abstract: A vaginal dilator having side blades or having upper and lower blades comprising accessorial blades includes an upper blade (1), a press handle (3), a lower blade (2) and a handle (4). The upper blade (1) is connected with the lower blade (2) by a pin (5). The press handle (3) is engaged with the handle (4) by a first dilating fixation device. The vaginal dilator having side blades also includes a circular-arc movable locating sleeve (8) rotationally connected with the upper blade (1). Each end of the sleeve (8) is provided with a mounting base (11). The mounting base (11) is provided with a joint cavity for receiving a side blade (12) which can be retracted between the upper and lower blades (1, 2). The back portion of the side blade (12) is provided with a second dilating fixation device engaged with the back end of the upper blade (1) or a locating buckle (15) of the mounting base (11). A channel (18), a channel cover and a slot for inserting the channel cover are provided in the side blade (12).
