The invention relates to the technical field of stress measurement, in particular to a structural member stress detection device which comprises a protective shell, the cross section of the protective shell is arc-shaped, a stress sensor is mounted on the inner side of the protective shell, a connector is connected to the stress sensor through a wire, the connector is mounted on the inner side of a connecting device, and the connecting device is connected with the protective shell. A steel cable sealing structure is mounted on one side of the protective shell; the number of the connecting devices is two, and the connecting devices are distributed on the inner side of the protective shell. According to the invention, by arranging an anti-accumulated snow structure composed of a vibration motor, a vibration block, a guide plate and a spring telescopic rod, the device can actively vibrate off accumulated snow in a snowfall environment, and the effectiveness of long-term monitoring is ensured; by arranging the two slidable connecting devices in the protective shell, rigid clamping is not formed at the connecting point of the sensor, so that the device is prevented from generating extra constraining force on the steel cable, it is ensured that the measuring point is not interfered due to structural enhancement, and the authenticity of stress data is improved.

This application relates to the field of resource allocation technology, and discloses a heterogeneous resource scheduling method, a heterogeneous resource scheduling device, a computing device, and a computer-readable storage medium. Applied to a computing device, the computing device includes various computing resources. The method includes: parsing the task to be allocated, generating multiple subtasks and task attribute identifiers corresponding to each subtask; determining the execution order of the multiple subtasks according to priority; processing each subtask according to the execution order; calculating a cost function based on the task attribute identifiers and the target performance model of each computing resource; scheduling the subtasks to the computing resource with the minimum cost function; and simultaneously obtaining multiple target performance indicators fed back by the computing resources and updating the target performance model. Through the above method, the collaborative execution of heterogeneous resources is achieved, and it can adapt to dynamic changes in hardware performance, ensuring that all subtasks in the task to be allocated can be executed efficiently.

The invention provides a biased activated interleukin-2 with site-specific modification and an application thereof. The site-specific modified biased activated interleukin-2 comprises a sequence which has 90% homology with SEQ ID No.1 and one or more water-soluble polymers coupled to the sequence. The invention further discloses a preparation method of the site-specific modified biased activated interleukin-2. According to the site-specific modified biased activated interleukin-2, by screening polyethylene glycol PEG molecular modification sites, an IL2 conjugate with reduced affinity with CD25 can be obtained, the half-life period of the IL2 conjugate is prolonged while the side effect of the IL2 is reduced, and better anti-tumor activity is achieved.

The application discloses a virtual RDMA device based on DPDK and a use method thereof. The virtual RDMA device based on DPDK comprises a front-end virtio-rdma device, which is used for receiving an RDMA device operation request initiated by an application program in a virtual machine, encapsulating the request as an instruction conforming to a virtio protocol, and sending the instruction to a back-end vhost-user- rdma device through a vring; and the back-end vhost-user- rdma device is used for simulating the function of a real RDMA network card, the device can acquire and analyze the instruction conforming to the virtio protocol from a circular queue vring, execute corresponding RDMA device operations, and return the operation results to the front-end virtio-rdma device through the vring. The application can get rid of the dependence on the real RDMA device, and can improve the resource utilization, system flexibility and safety.
