The activation energies of the grain-boundary and different polarizations are researched to reveal effect segregation structure on performance.
The study aims to clarify the temporal and spatial evolution characteristics of landscape ecological risk in Hailar River basin recent 30 years, serve for scientific formulation management strategies. In study, ecosystem services were used improve traditional assessment method, theoretical basis was clarified using human-nature system method. results show that, on scale, overall is characterized by high middle low around. high-risk areas are mainly located transition zone "urban-grassland"...
In the field of defect detection in sewers, some researches focus on high accuracy. However, it is challenging for portable on-site devices to provide performance. This paper proposes a lightweight sewer model, You Only Look Once (YOLO) v5-Sewer. Firstly, backbone network YOLOv5s replaced with stacked MobileNetV3 block. Secondly, C3 module neck improved C3-Faster module. Thirdly, compensate accuracy loss due network, channel attention (CA) and convolutional block (CBAM) are added proposed...
Immunoglobulin‑like transcript (ILT) 4, a negative regulator of immune response in allograft rejection, autoimmunity and infectious diseases, has recently been determined to serve important roles tumor development. In the present study, co‑expression ILT4 human leukocyte antigen‑G (HLA‑G) tissues primary colorectal cancer (CRC) was revealed, its association with older age, advanced stage, regional lymph node involvement poor overall survival time identified. CRC cell lines, HLA‑G their...
In order to improve the dynamic performance of legged robots, this paper proposes a method for optimizing parameters leg mechanism based on motion. The proposed consists two key parts as follows: support optimization and transmission optimization. For mechanism, analysis index robot motion energy is introduced evaluate performance. Under structure stiffness constraint, can quantitatively analyze influence range mass performance, thereby guiding design such motion, thickness, U-flange...
In unpredictable scenarios, quadruped robots with behavior-controllable capabilities can often improve their adaptability through interaction users. this paper, we propose a motion control method, integrating user commands adversarial priors, enabling the robot to achieve capabilities. Firstly, trajectory library is constructed provide prior knowledge. To obtain stable data for various motions, optimal methods are used generate dynamic trajectories whole-body constraints. These then...
Aiming to solve the problem of clearing obstacles in narrow and complex sewers, this paper introduces a visually assisted Sewer Cleaning Robot (SCR) for cleaning sewers with diameters ranging from 280 780 mm. The main work is carried out as follows: (a) A mobile platform equipped pressing mechanism press against pipe walls different diameters. arm uses high-load linear actuator structures, enhancing load capacity while maintaining stability. (b) Detection–Localization–Cleaning mode proposed...
Mutations in Gap Junction Beta 2 (GJB2) have been reported to be a major cause of non-syndromic hearing loss many populations worldwide. The spectrums and frequencies GJB2 variants vary substantially among different ethnic groups, the genotypes these remain poorly understood. In present study, we carried out systematic extended mutational screening gene 1067 Han Chinese subjects with loss, resultant were evaluated by phylogenetic, structural bioinformatic analysis. A total 25 (23 known...
The coupling coordinated development of production-living-ecology (PLE) system is great importance to sustainable development. However, the influencing factors for PLE remain poorly understood, especially in terms spatial and temporal differences among main factors. In this study, we chose panel data 295 China's prefecture-level cities from 2007 2019 explore spatiotemporal characteristics using model, regression GTWR model K-means clustering method. From our results, index showed an...
Vehicle driving can substantially enhance the maneuverability of humanoid robots. Agile steering wheel manipulation requires rapid rotation in narrow spaces such as a cab, serving foundation for increasing speed, especially an obstacle avoidance scenario. Generally, there are 3 human strategies, "Hand-to-Hand," "Hand-over-Hand," and "One-Hand." Based on motion data, we quantitatively analyze these strategies from aspects, range joint combination, region shoulder, velocity manipulation. Then,...
Abstract The association between insomnia and metabolic syndrome remains unclear, especially among different-aged groups. A cross-sectional study with 8017 participants was performed to identify whether associated or not. Demographic characteristics, lifestyles other risk factors were collected using a predesigned, semi-structured, self-administered questionnaire, physical examinations conducted by certificated community physicians. Insomnia not independently across all subjects; however,...
Abstract Decreasing vegetation cover leads to serious environmental problems, with negative impacts on human health and socioeconomic development. In recent years, these problems have seriously threatened societies around the world. Although there been many studies of urbanization's natural land cover, ecosystem health, biodiversity, effects spatial variation factors their interaction climate are less well known, particularly in rapidly developing countries such as China. This makes it...
A new unconditionally stable finite-difference time-domain (FDTD) method for periodic structures is presented, which based on the field transformation and weighted Laguerre polynomials FDTD (WLP-FDTD). The proposed uses a to remove time gradient across grid, then concept of WLP-FDTD get implicit relationship between transformed variables. It holds advantages WLP-FDTD, can eliminate restriction Courant-Friedrich-Levy (CFL) stability condition. Compared with other transform methods, needn't do...
Research on the social-ecological system unifies society, economy, resources and environment provides an integrated systematic research framework through which to study complex earth problems, such as climate change, globalization, land use/cover change population growth. This aims provide support for excavation of deep-seated coupling mechanism by revealing basic structure this answer following three questions. What are elements system? correlations between elements? How does work? The...
Malware detection is of great significance for maintaining the security information systems. obfuscation techniques and malware variants are increasingly emerging, but their samples API (application programming interface) sequences difficult to obtain. This poses difficulties development variant models. To address this issue in paper, we first generated a dataset using technique based on disassembly decompilation malware. Then, an call these was constructed through sandboxing. Compared...
