Article Synopsis
- Existing mechanical and grouting anchors use an expansion shell method for creating cavities, which complicates operations and results in smaller plates.
- The paper introduces a new large-diameter multi-plate soil anchor and a tool to create enlarged head plates more easily.
- Simulation analysis shows that for optimal performance, a 590 mm anchor plate diameter, six anchor plates, and 800 mm spacing between them are ideal, balancing load distribution and strain on the soil for maximum uplift capacity.
This article develops a cooperative-critic learning-based secure tracking control (CLSTC) method for unknown nonlinear systems in the presence of multisensor faults. By introducing a low-pass filter, the sensor faults are transformed into "pseudo" actuator faults, and an augmented system that integrates the system state and the filter output is constructed. To reduce design costs, a joint neural network Luenberger observer (NNLO) structure is established by using neural network and input/output data of the system to identify unknown system dynamics and sensor faults online.

Under the framework of the synergetic learning structure (SLS), the optimal control input and the actuator failure are viewed as two subsystems. Then, the fault tolerant control (FTC) problem can be regarded as a two-player zero-sum differential game according to the game theory.

Methods: 24 cases of postoperative colorectal cancer tissues and 36 cases of mucosa tissues were selected as experimental group and control group, respectively. Circ-ZNF609 expression in colorectal cancer tissues and mucosa tissues were detected by quantitative real-time PCR (qRT-PCR).
