Abstract: A virtual switching method, a related apparatus, and a computer system are provided. The method includes the Host configures virtual environment between a source node and a target node in combination with an agent module, receiving a first message sent by a source node, where the first message is used to request a first virtual machine to perform switching processing on to-be-switched data, where the to-be-switched data is sent from the source node to a target node and at least one of the source node and the target node is a second virtual machine; and determining a second message according to an address of the target node contained in the to-be-switched data and a configured port mapping table, and sending the second message, where the second message is used to instruct the target node to acquire the to-be-switched data from a storage device of a hardware layer.

Abstract: Provided are a method and apparatus for acquiring a port range resource, and method and apparatus for allocating a port range resource. In the method, a first Router Solicitation (RS) message is sent to a server-end device, wherein information carried in the first RS message includes at least one of an Internet Protocol (IP) address multiplexing request and a port range resource allocation request; and a Router Advertisement (RA) message from the server-end device is received, wherein information carried in the RA message includes: a port range resource allocated according to the IP address multiplexing request and/or according to the port range resource allocation request. By virtue of the technical solution, an Address Plus Port (A+P) technology can be applied to an application scenario where stateless configuration of an Internet Protocol Version 6 (IPv6) address is performed via Neighbour Discovery (ND), thereby expanding the application range of the A+P technology.

The composition comprises: 100 parts by weight of high-viscosity nylon powder, 1-5 parts by weight of a flow agent, and 0.1-1 parts by weight of an antioxidant; the high-viscosity nylon powder is one or more selected from nylon 6, nylon 66, nylon 11, nylon 12, nylon 612 and nylon 610; or the powder composition is obtained via polymerization reaction of the raw materials comprising the following components, based on the weight parts of lactam monomers or amide monomers: 100 parts by weight of lactam monomers or amide monomers, 0.005-1 parts by weight of a catalyst, and 0.1-1 parts by weight of an antioxidant.

Abstract: A linear regulator includes a drive circuit having an input and an output, with the output configured to drive a control terminal of a power transistor for the delivery of a load current. An error amplifier functions to amplify a difference between a reference signal and a feedback signal to generate an error signal at the input of the drive circuit. A compensation circuit includes a series circuit formed by a compensation capacitor and a variable resistance circuit, where the series circuit is coupled to the input of the drive circuit. A current sensing circuit operates to sense the load current. The resistance of the variable resistance circuit is varied in response to the sensed load current.

Abstract: A double tilt sample holder for in-situ measuring mechanical and electrical properties of microstructures in transmission electron microscope (TEM) is provided. The sample holder includes a home-made hollow sample holder body, a sensor for measuring mechanical/electrical properties, a pressing piece, a sample holder head, a sensor carrier. The sensor for measuring mechanical/electrical properties is fixed on the sensor carrier on the sample holder head by the pressing piece, while the sensor carrier is connected to the sample holder head through a pair of supporting shafts located on sides of the sample holder head. The sensor carrier can tilt within the plane perpendicular to the ample holder head by revolving around the supporting shafts (i.e. tilting along Y axis at an angle of ±30°). The sample holder also allows obtaining mechanical/electrical parameters concurrently.

Abstract: A system for organizing a variety of information related to a user is disclosed. A user may input geo-tagged multi-modal information into a mobile device. This data is automatically transferred to cloud computing resources, and made available for access by the user at a desktop or laptop computing device. After input, an implicit search based on the geolocation of the input may be undertaken and results provided to the user. Input may be flags to designate a personal point of interest (PPOI), for sharing with others, for enabling location or people-based reminders, and so forth. Reminders for upcoming activities are provided to the user such that the user has sufficient time to move from the current geolocation to the geolocation of the activity.
