The path tracking system is a crucial component in fully autonomous vehicles. While many methods provide stateof-the-art performance, they tend to emphasize accuracy for safety, at the price of ride quality. Although based on dynamic model and optimization theory guarantee improved high-fidelity unavailable most systems, complex process may increase computational burden. Therefore, practical, real-life it urgent develop method with simple, effective control framework real-time...

'Xianglin 14' significantly higher...
Camellia meiocarpa Hu, a member of Youcha species in the genus Camellia, is an important woody edible plant with high ecological and economic value. The haplotype-resolved genome assembly this tetraploid can shed light on genomic evolution functional divergence among subgenomes haplotypes. In study, we achieved first chromosome-level using PacBio HiFi, Hi-C, Illumina sequencing. scaffolds, N50 44.46 Mb 41.40 Mb, were mapped to 60 chromosomes four distinct haplotypes, each unique transposon...
In this paper, the adaptive robust tracking control scheme is proposed for a class of multi-input and multi-output (MIMO) non-affine systems with uncertain structure parameters, unknown direction external disturbance based on backstepping technique. The MIMO system first transformed into time-varying strict feedback using mean value theorem, then bounded parameters are estimated by algorithms projection. To handle possible "controller singularity" problem caused direction, Nussbaum function...
User behavior threat detection is important for the protection of network system security. Traditional supervised modeling methods and unbalanced sample data lead to a high false positive rate in user detection. In addition, behaviors are complex, changeable, difficult predict, existing facing ever greater challenges. Effectively detecting remains challenge. this paper, we propose method based on an Adaptive Sliding Window Generative Adversarial Network(ASW-GAN). This designs adaptive...
Emerging communication-based control and virtually coupled train formations are critical foundations for automatic operations to improve capacity, safety flexibility toward intelligent rail transportation systems. High-reliability cooperative of heavy haul (HHT) encounters greater challenges due the distinctive dynamic characteristics uncertainties. This paper proposes a distributed global composite learning protocol that enables all HHTs achieve autonomous steady coordination with minimum...

By enabling the barriers to vary with prescribed performance functions time, an asymmetric performance‐barrier Lyapunov function (APP‐BLF) developed guarantee tracking simultaneously constraint satisfaction under arbitrary switching, while initial conditional requirements are relaxed. To...
Increased nitrogen deposition is a key feature of global climate change, however, its effects on the structure and assembling mechanisms nitrogen-fixing bacteria present at root surface remain to be elucidated. In this pursuit, we used NH 4 NO 3 simulate in 10-year-old Camellia oleifera plantation, set up four treatments, including control N0 (0 kg N hm −2 −1 ), low N20 (20 medium N40 (40 ) high N160 (160 ). The results showed that affected soil content bacterial community. Low was conducive...
Camellia oleifera Abel. is one of the world’s four famous woody oil trees and has drawn increasing attention because its high commercial value. Endophytes are microorganisms inhabiting inside plant tissues, their functions vary with change host status environmental parameters. To deepen our understanding interactions between C. endophytic actinobacteria, present study investigated actinobacterial composition-residing high-yield trees. A total 156 isolates were obtained distributed in 17...
Arbuscular mycorrhizal fungi (AMF) symbiosis has been shown to improve the ability obtain nutrients and resist adverse environmental conditions. However, there are few studies on functions of AMF in absorption accumulation boron (B). Moreover, it is still unclear whether root colonization rates limited by B deficiency. In this study, Camellia oleifera seedlings were planted normal boron-deficient substrates, inoculated with Funneliformis mosseae or left uninoculated. The growth physiological...
Urban driving requires the autonomous vehicles to drive with smooth control and track planned path accurately. However, most of existing path-tracking controllers pay more attention tracking errors than smoothness because difficulties balance them. This paper proposes a learning-based method achieve trade-off between tracking-error control. An Reinforcement Learning algorithm, which is called Proximal Policy Optimization, used train neural model tune weights designed controller PP_PID...
Plant polysaccharides, a type of important bioactive compound, are involved in multiple plant defense mechanisms, and particular polysaccharide-alleviated abiotic stress has been well studied. Polygonatum cyrtonema Hua (P. Hua) is medicinal edible perennial that used traditional Chinese medicine rich polysaccharides.
