Abstract: The present disclosure provides a multi-factor quantitative analysis method for deformation of a neighborhood tunnel. The method includes the following steps: analyzing monitoring data generated at a tunnel site; simulating collapse occurring at a shallow buried section of a tunnel; determining the degree of influence of each factor on the tunnel and a stratum; and determining quantitative influence of each factor on tunnel deformation. The present disclosure can not only provide an accurate theoretical basis for the construction of the shallow buried section of the small-distance tunnel, but also guarantee safety and cost saving during tunnel construction.

Abstract: A redundancy method includes that a first disaster management function (DMF) device on a first site side receives a first request including identification information of a first virtual machine (VM) and a recovery point objective (RPO), allocates a maximum allowable delay time to each node that input/output (IO) data of the first VM passes through in a redundancy process, and sends a second request to a second DMF device on a second site side. The second request includes a maximum allowable delay time of a second replication gateway function (RGF) device on the second site side, and a maximum allowable delay time of an IO writer function (IOWF) device on the second site side and requests the second site side to perform redundancy on the first VM. Hence, the RPO requirements of the tenants can be satisfied in an entire redundancy process.

A hydrogen introduction apparatus is configured to introduce a reducing agent including hydrogen to the ion source. The reducing agent is configured to alter a chemistry of the non-conducting material to produce a volatile gas by-product. A beamline assembly is configured to selectively transport the ion beam, and an end station is configured to accept the ion beam for implantation of ions into a workpiece.

Abstract: A method and an apparatus for migrating a virtual machine across virtualization systems, and a system, where a first virtualization system in which a source virtual machine is located specifies a temporary address of a destination virtual machine. After a second migration tool of a second virtualization system migrates the to-be-migrated virtual machine to the second virtualization system to generate the destination virtual machine, a first migration tool of the first virtualization system controls a migration agent on the destination virtual machine to modify the address of the destination virtual machine to an address of the source virtual machine such that the address of the virtual machine remains unchanged before and after migration, thereby shortening service interruption duration caused by virtual machine migration.

Abstract: An ion implantation system is provided having an ion source configured to form an ion beam from aluminum iodide. A beamline assembly selectively transports the ion beam to an end station configured to accept the ion beam for implantation of aluminum ions into a workpiece. The ion source has a solid-state material source having aluminum iodide in a solid form. A solid source vaporizer vaporizes the aluminum iodide, defining gaseous aluminum iodide. An arc chamber forms a plasma from the gaseous aluminum iodide, where arc current from a power supply is configured to dissociate aluminum ions from the aluminum iodide. One or more extraction electrodes extract the ion beam from the arc chamber. A water vapor source further introduces water to react residual aluminum iodide to form hydroiodic acid, where the residual aluminum iodide and hydroiodic acid is evacuated from the system.

A distal end portion of the body is covered with an end cap, which is integrally connected to the cuff and to the disposable forceps passage tube. The end cap is made of transparent elastic material with an elongated opening, compatible in shape to an opening of the distal end portion of the duodenoscope body, and further comprises a soft connection port in a shape of a pipe with a small-orifice end secured onto the disposable forceps passage tube, and a large orifice end secured onto an edge of the elongated opening. A forceps-lifting unit is disposed at the distal end portion of the duodenoscope body, and comprises a grooved pulley coupled with a steel wire for maneuverability.

Abstract: In the website system of the application, when a client accesses a page of a website, a web server obtains an initial URL of a content file included in the to-be-accessed page and a version parameter of a current version of the website, generates a current URL of the content file, and adds the version parameter to a search part of the current URL of the content file, so that the client can obtain the content file from the web server according to the current URL. During version upgrade of the website, a developer does not need to change a path to a content file, does not need to manually change a URL of the content file, and does not need to update a name of the content file either. This improves website upgrading efficiency.

Abstract: The present disclosure is for an endoscope assembly comprising an endoscope and a disposable sheath cover. The endoscope comprises an illumination window adjacent to an observation window situated along a lateral side of a distal end portion, and an elongated slot to accommodate biopsy instruments. The sheath further comprises an end cap fitted around the end portion of the endoscope with a capsule secured to its inner wall. When the end cap engages the endoscope, the capsule is ruptured to release a transparent liquid immersing the illumination window and the observation window. A soft connector is bonded to the end cap covering the elongated slot, and to an outer surface of a biopsy channel. The soft connector further comprises an opening allowing the biopsy channel to pass through. The sheath can accommodate air/water tubes, and is secured onto the shaft of the endoscope via a cuff.
