In order to ensure the accuracy of motion in complex terrains for quadruped robots, a real-time gait monitoring method based on machine learning and binocular vision was proposed. The residual visual error was addressed by identifying the optimal observation point for the foot end along the known gait trajectory, which was referred to as “ capturing stillness amid motion”. To compensate for measurement errors in foot position and posture due to inaccuracies in the vision system, an accurate prediction method based on a depth neural network was utilized. The simulation results indicate that the designed neural network achieves a 99. 68% probability of attaining 0. 025 mm foot position prediction accuracy, thus fulfilling the requirements for real-time and high-precision monitoring. It is concluded that the proposed method combines the generalization capabilities of machine learning with the complex error sources of the vision system to achieve high-precision measurement. Consequently, it provides a novel perspective for real-time and accurate gait monitoring of foot robots and serves as a valuable reference for foot end positioning and periodic gait maintenance.

Asthma, a prevalent respiratory disease, remains incompletely understood in terms of its pathogenesis. Airway remodeling, a prominent feature of asthma, occurs early in the disease process. Airway smooth muscle cells (ASMC) are recognized as a critical target in asthmatic airway remodeling, and the phenotypic transformation from normal contraction to proliferation/synthesis is one of the important characteristics of airway remodeling. Autophagy, a cellular process that serves as a defense mechanism, plays a significant regulatory role in the pathogenesis of asthma, particularly in the phenotype transformation of ASMC to promote airway remodeling. In this paper, we review the relationship between autophagy and phenotype transformation of ASMC, as well as relevant findings in the context of asthma pathogenesis, with the aim of inspiring future research endeavors in this field.

Seepage damage is widely present in engineering construction such as embankments, foundation pits, and tunnels. It can directly lead to structural failure, casualties, and property losses. Therefore, it is urgent to reveal the mechanism of rock and soil seepage damage, and propose safe and effective engineering prevention and control measures. The mechanism of seepage failure in soil -flow and piping was analyzed and explained. It is believed that the occurrence of seepage failure depends on the physical and geometric properties of the rock and soil itself and the strength of external hydraulic factors. When the seepage force is greater than the effective gravity of soil particles, soil-flow failure occurs, and piping failure occurs when a through channel is formed inside the rock and soil. The prevention and control principles of rock and soil seepage damage disasters such as seepage, compaction, and splitting grouting were elaborated, and a discussions was conducted on composite and ultra-fine cement, geopolymer, high polymer, microbial liquid and other grouting prevention and control materials, aiming to provide technical support for the prevention and control of rock and soil engineering diseases.

To address the issue of holistic ecological protection in a situation where various environmental factors intertwine, the Yangtze River Protection Law has established the orientation and concept of ecosystem integrity and the ecological space systematization. Based on the data of wetland resources before and after the promulgation of the Yangtze River Protection Law, this paper analyzes the inadaptability between the wetland property right system and the traditional property right system by using the methods of normative analysis, comparative analysis, and empirical analysis, and puts forward solutions. Constrained by the inherent structural defects of the traditional property right system, the wetland property right system has many problems in practice, such as system value deviation, system function dislocation, system implementation block, etc., but it has a new possibility of system improvement in the selection of basic principles, the allocation of internal powers, and the definition of legal relationship objects. This paper further proposes that China should clarify the basic position of ecological value in the wetland property right system, adjust the management mode of wetland property rights based on the integrity of the ecosystem, and improve the registration method of the wetland property right system for ecological space. The specific path of system optimization is as follows: first, the principle of ‘prioritizing ecological conservation and boosting green development’ should be established as the basic principle of the wetland property right system; second, the registration results of wetland property right confirmation and the ecological information of wetland property rights should be bound before being made public voluntarily; third, the boundary of natural resources and internal administrative responsibilities of wetland property rights should be planned as a whole; fourth, the wetland property right system should be institutionally connected with the ‘river chief system’; fifth, the information of wetland property rights should be linked to the performance assessment of leading officials; sixth, surveying and mapping indicators, subjects, and methods should be clearly defined in the wetland property right system and ‘landscape change standards’ should be introduced accordingly.

Objective: To investigate the effects of simulated hypobaric hypoxic environment at 5000 m altitude on intestinal tissue structure, immune factors, and gut microbiota in mice with different hypoxia exposure times. Methods: 72 male C57BL/6 mice were divided into hypoxia groups and control groups. The hypoxia model was established by hypobaric chamber with simulated altitude of 5000 m. The hypoxia groups were set for 1, 3, 5, 7, 14, and 30 days (6 mice per group, hypoxia time 24 h per day), body weight of mice was recorded. The histopathological sections of ileum were made by HE staining. The expression levels of occludin, an intestinal tight junction protein, were analyzed by immunohistochemical staining. The levels of IL-6, IL-22, and TNF-α in plasma were detected by enzyme-linked immunosorbent assay (ELISA). Gut microbiota was analyzed by 16 s rDNA sequencing. Results: Compared with that in the control group, the body weight of hypoxia groups reduced significantly (P<0.05). HE staining and immunohistochemical staining of hypoxia groups showed that there were injury in intestinal epithelial villi and the lymphocytes increased. The expression of occludin protein decreased significantly(P<0.05) in 7- and 14-day hypoxia groups. IL-6 in plasma decreased significantly(P<0.05) in 7-day hypoxia groups and then increased significantly(P<0.05) in 14-day hypoxia groups. The characteristics ofthe intestinal microbial community ofmice in different hypoxia exposure groups and control groups significantly changed. At genus level, the abundance of Prevotella, Akkermansia, Oscillospira, Bacteroides, Desulfovibrio, Odoribacter were significantly increased (P<0.05) in hypoxia groups. Correlation analysis of immune factors and gut microbiota showed that Lactobacillus is significantly positively correlated with IL-6 and IL-22 (r=0.27, P<0.05; r=0.27, P<0.05). Conclusions: Hypoxia stress at an altitude simulating 5000 m significantly changed the intestinal epithelium structure and barrier function and the composition of gut microbiota of mice. Changes in gut microbiota were significantly correlated with the levels of immune factor in plasma. These changes may be the adaptive response to the hypoxia environment and are related to the time of hypoxia stress. [ABSTRACT FROM AUTHOR]

In order to address the issue of low forecast accuracy due to the lack of observation data in traditional hydrological forecasting mod Is, generative adversarial network (GAN), with the characteristic of generating data by learning data distribution, could be used to combine with the long and short-term memory (LSTM). Firstly, the "binary minimax" game theory of GAN was used to solve the issue of data missing by generating padding data that was consistent with the distribution of the missing data and was able to represent the characteristics of the missing data. Then the integrated padding data was input into the LSTM for hydrological forecast. Finally, the experimental results on the measured hydrological data set collected by Qingxi Hydrological Station of the Qingxi River showed that the prediction performance of the pro posed model under the condition of missing data was significantly better than that of other similar models.

With feedback control method, the physical layer security scheme via noise aggregation can degrade the eavesdropper's channel quality and enhance the security performance of communication system by fully extracting the resources of inherent noise in wireless communication. In order to validate and evaluate the performance of the scheme, this paper designed and realized a practical scheme for transmitter and receiver with anti-wiretapping functions based on software defined radio platform. On basis of that, this paper established the anti-wiretapping test environment, which includes a source node, a destination node and an eavesdropper node. Taking the test case of image transmission, this paper evaluated some objective indicators, such as frame error, peak signal noise rate and the subjective quality of images. Test results show that there is satisfied SNR gain between Bob and Eve for the same frame error rate. Moreover, clear and recognized received images with higher peak signal noise rate prove the effectiveness of the noise aggregation scheme. [ABSTRACT FROM AUTHOR]

An “inverse” unscented Kalman filter (UKF) algorithm with seven-dimensional state vector is proposed to solve the problems of low target positioning accuracy and poor fire direction ability of firefin-der radar. A state model is established by taking the ballistic coefficient as the state parameter and incorporating it into the filtering process. The UKF algorithm is used to improve the nonlinear estimation accuracy. The model error accumulates due to the long extrapolated distance of forward filtering. In the proposed algorithm, an inverse filtering is used, the first point measured by radar is used as the end point of the filter, and the artillery position is extrapolated using the fourth-order Runge-Kutta equation. The simulation results show that the proposed algorithm can effectively improve the extrapolation accuracy of artillery locating and fire correction radar. [ABSTRACT FROM AUTHOR]
