Abstract Muscles featuring high frequency and stroke linear actuation are essential for animals to achieve superior maneuverability, agility, environmental adaptability. Artificial muscles yet match their biological counterparts, due inferior speed, magnitude, mode, or Inspired by the hierarchical structure of natural muscles, artificial created that powerful, responsive, robust, adaptable. The consist knots braided from 3D printed liquid crystal elastomer fibers thin heating threads. unique...
Background This study aimed to construct and validate diagnostic models for the Operative Link on Gastritis Assessment (OLGA) Gastric Intestinal Metaplasia (OLGIM) staging systems using three different methodologies based magnifying endoscopy with narrow-band imaging (ME-NBI) features, evaluate model performance, analyse risk factors high-risk OLGA/OLGIM stages. Methods We enrolled 356 patients who underwent white-light ME-NBI at Department of Gastroenterology, Dongzhimen Hospital, Beijing...

The fault-crossing tunnel in meizoseismal area is directly subjected to strong ground motion, which leads the failure of lining. In order improve seismic safety tunnel, fiber-reinforced concrete applied lining this article. Taking section Zhongyi crossing Wanlong fault as an example, performance was studied by finite difference numerical calculation software FLAC3D. displacement, stress response, and side wall convergence secondary structures are plain concrete, steel steel-basalt hybrid...
Automatic driving is gradually being popularised, and automatic control of automobile steering by wire has also become a topic worthy research. The research combines the fuzzy algorithm PID to construct strategy, integrates genetic into basic rules form an improved new algorithm. mainly focuses on multiple changes in steering-by-wire car, including angular momentum, velocity, linear velocity acceleration, build more complex then use three most parameters PID. results show that average...
This letter proposes a learning-based adaptive propulsion control (APC) method for quadruped robot integrated with thrusters in amphibious environments, allowing it to move efficiently water while maintaining its ground locomotion capabilities. We designed the specific reinforcement learning train neural network perform vector control. Our approach coordinates legs and propeller, enabling achieve speed trajectory tracking tasks presence of actuator failures unknown disturbances. simulated...
Due to their ability adapt different terrains, quadruped robots have drawn much attention in the research field of robot learning. Legged mobile manipulation, where a is equipped with robotic arm, can greatly enhance performance various manipulation tasks. Several prior works investigated legged from viewpoint control theory. However, modeling unified structure for arms and challenging task. In this paper, we propose framework disturbance predictive reinforcement learning scheme latent...
Abstract. From July to September 2009, a set of multi-channel seismic data was collected in the northern shelf area South China Sea. After processed, we observed series shoaling events on one survey lines, including high-frequency internal waves, high-mode nonlinear and shear instability. Using theoretical results from previous numerical simulations field observations, coupled with local temperature salinity data, analyzed their depth distribution, waveform characteristics, formation...
The subarctic Bering Sea, situated between the Pacific Ocean and Arctic Ocean, stands as one of world's most productive oceanic regions. While role eddies in material transport energy transfer has been extensively studied, surface have dominated these investigations owing to advancements remote sensing technology. Recently, attention shifted subsurface for their influence on enhancing mixing. However, challenges persist delineating distribution characteristics Sea due limited effectiveness...
Seismic oceanography has been widely used in the study of internal solitary waves (ISWs) recent years, and achieved remarkable results. In this paper, we analyzed multi-channel seismic reflection data Canterbury Basin offshore New Zealand from January 9 to 29, 2000, collected by R/V Maurice Ewing. We observed 4 groups ISWs (labeled ISW1s ISW4s) on survey lines. studied their waveforms propagation speeds detail. There are two theoretical structures describe vertical waveform ISWs: first-order...
Thermohaline staircases and mesoscale eddies play crucial roles in the transport of heat, salt, nutrients ocean, yet their complex relationship remains unclear due to limitations observational resolution lateral range. Here, utilizing high spatial seismic images with a total length 2518 km, we show widespread occurrence thermohaline eastern Caribbean Sea demonstrate three-dimensional distribution. These occupy about 70% lines, remaining 30% occupied by six subsurface eddies. are disrupted...
Abstract. The shoaling and breaking of internal waves (IWs) are critical processes in the ocean's energy cascade mixing. Using seismic data, we observed high-frequency (HIWs), which were primarily distributed depth range 79–184 m. Their amplitude scale is O (10 m), with half-height widths ranging from 154 to 240 thermocline gentle slope a low Iribarren number suggest that likely result fission. remote sensing data support this point. Instability estimations showed that, due strong vertical...
