Keywords: Nonlinear system Unmanned aerial vehicle Input saturation Recurrent wavelet neural network Disturbance observer Dynamic surface control a b s t r a c t In this paper, the robust tracking control scheme is proposed for a class of uncertain multi-input and multi-output (MIMO) nonlinear systems with input saturation and unknown external disturbance(More)
The exosome is a key initiator of pre-metastatic niche in numerous cancers, where macrophages serve as primary inducers of tumor microenvironment. However, the proteome that can be exosomally transported from cancer cells to macrophages has not been sufficiently characterized so far. Here, we used colorectal cancer (CRC) exosomes to educate tumor-favorable(More)
This paper is according to the illustration of intensity of rainfall-duration of rainfall and the critical precipitation theory which refers to the relationship between rainfall and the happening of landslides, taking the main types, scale, time and spatial distribution and the actual extent of damage of geologic hazards in Hubei province into(More)
In this paper, the author taking the geological problem of environment and occurred geological disasters evaluating objects, apply GIS HAP to evaluate three subsystems of rock environment, environmental soil, water environment which affect the quality of geological environment of Wuhan megalopolis. By analyzing the main factors which affect the subsystems,(More)
This paper is according to the illustration of intensity of rainfall--duration of rainfall and the critical precipitation theory which refers to the relationship between rainfall and the happening of landslides, taking the main types, scale, time and spatial distribution and the actual extent of damage of geologic hazards in Hubei province into(More)
The utilization of cemented tailings/paste backfill (CPB) by the mining industry is becoming increasingly important. However, it has been difficult to analyze the economic usage of CPB for fine unclassified tailings. Therefore, the physical and chemical properties of fine unclassified tailings, sampled from the Sijiaying Mine, were first analyzed in this(More)
