The present disclosure belongs to the field of biotechnology, and specifically relates to a method for efficiently infecting human natural killer (NK) cells and other immune cells with a pseudovirus. Specifically, a viral transfection system provided in the present disclosure has an envelope plasmid with a protein having an X-Y-Z structure. The X is an extracellular (ex) structure of a gibbon ape leukemia virus (GALV) envelope glycoprotein, the Y is a transmembrane (TM) structure of the GALV envelope glycoprotein, and the Z is an intracellular segment portion of a murine virus gene.

The Invention discloses a self-supplied hydrogen fuel cell system and a working method thereof, the system comprising a diesel tank, a gas separator, a fuel cell, a low-temperature separation reactor, a high-temperature separation reactor, an auto-thermal reformer, a water tank and a catalytic burner; With the high-temperature separation reactor, the low-temperature separation reactor and the auto-thermal reformer, diesel is cracked into Hand CO; as the fuel for the fuel cell, Hmay react with Oin the air and generate electric energy; the unreacted Hand CO enter into the catalytic burner for combustion, ensuring that the water is heated; thus, it not only provides Hto the fuel cell, but also provides high-temperature water to the auto-thermal converter to produce H; electric energy can be generated without burning diesel; since no NOor particulate matters but COis generated, the goal of ultra-low emission is achieved.

Disclosed are a method for component access control and electronic device. The method comprises: acquiring a target component list corresponding to the first application, which list includes at least one target component required by the first application, with the at least one target component belonging to at least one basic component; after a component selection command is received, generating information about those basic components accessible by the first application from the target component list according to the component selection command; and storing the information about those basic components accessible by the first application. In the present solution, it is unnecessary to set access to all the component when applying for an application; rather, those component accessible by the application can be controlled during the installation or use of the application according to system or user requirements, thereby increasing the flexibility of the application in accessing components and reducing the probability of the user privacy being stolen.

Method for component access control and electronic device

Embodiments of the present disclosure provide an authentication method and an electronic device. The method includes: generating by a first device an authentication request if a predetermined condition exists between the first device and a second device, when the first device is in a locking state, wherein the first device has the locking state and a non-locking state; receiving by the first device authentication information, the authentication information being input in response to the authentication request; and authenticating the second device using the authentication information. Through the present disclosure, others cannot directly damage or copy data in the first device in a connection manner such as using a data line even if they get hold of the device, as long as the first device is in the locking state. Thus, the security of the data in the first device is ensured. Since a complex synchronization authentication protocol does not need to be developed by synchronization software and the first device, and the present disclosure is compatible with various commercially available synchronization software, the implementation method is simple and efficient, and the compatibility is good.

The present invention provides a virtual machine system and a method for sharing a graphics card amongst virtual machines. A VMM of the virtual machine system is provided with a resource-converting module, which converts data exchanged between a graphics card drive module of a GOS in the foreground and the graphics card based on a resource-converting table, and also intercepts accesses to the real graphics card by a GOS in the background and then responds to its operations on the graphics card. The VMM is further provided with a switching module, which alters a state of a VM based on a command for switching the VM, saves a graphics card state before the VM is switched to the background and restores the stored graphics card state to the graphics card when the VM is switched back to the foreground. Further, the GOSs each comprise a graphics card drive module corresponding to the real graphics card for accessing the real graphics card. The systems and the methods according to the present invention enable the GOSs to access the real graphics card, and also enable switching among a plurality of virtual machines.

The present invention provides a method and a computer system for sharing a graphics card among multiple Operation Systems (OSs). The method includes: detecting a first GOS to be displayed, the first GOS being a primary GOS or one of at least one secondary GOS; determining the kind of the first GOS, so that different display control register bank(s) and graphics card memory resources are allocated to the first GOS depending on whether it is a primary GOS or a secondary GOS; controlling the display control register bank(s) allocated to the first GOS to connect to a display output port; obtaining display contents based on the graphics card memory resources allocated to the first GOS; and displaying the display contents based on display mode parameters in the display control register bank(s) connected to the display output port. According to the present invention, it is possible to share the graphics card among the multiple OSs without modifying the drivers of the primary GOS.

The present invention provides a control method for switching display between a plurality of OSs as well as a computer system. The method comprises: detecting that the currently displayed guest operating system (GOS) is required to be switched from a first GOS to a second GOS; determining whether the first GOS satisfies a preset switching condition, and switching the currently displayed GOS to the second GOS if the preset switching condition is satisfied, and otherwise, prohibiting the switching from the currently displayed GOS. With the method and the computer system, it is possible to avoid picture distortion or blurring or system collapse in switching display between a plurality of OSs.

The present invention provides a virtual machine system and a method of accessing a graphics card. The virtual machine system includes a VMM, an SOS and at least one GOS, and further includes a resource converting module for performing IO address converting on graphics card framebuffer accessing data from GOS(s) or mapping MMIO(s) to physical MMIO(s) of a graphics card based on a resource converting table, and sending the processed data to the graphics card; and a framebuffer allocating module for dividing a framebuffer resource of the graphics card into multiple blocks and allocating them respectively to corresponding GOS(s). The resource converting table(s) records correspondences between a resource allocation for the graphics card by SOS and a resource allocation for the graphics card by GOS(s). The framebuffer MMIO resource(s) allocated to the graphics card by GOS(s) is/are the framebuffer allocated to GOS(s) by the framebuffer allocating module.
