Abstract The wheel-legged hybrid structure has been utilized by ground mobile platforms in recent years to achieve good mobility on both flat surfaces and rough terrain. However, most of the wheel-legged robots only have...

Abstract The paper proposes a novel multi-legged robot with pitch adjustive units aiming at obstacle surmounting. With only 6 degrees of freedom, the robot with 16 mechanical legs walks steadily and surmounts the obstacl...

Abstract Composites are increasingly employed in aerospace, automotive, construction, sports, and defense industries owing to their high strength-to-weight ratio, corrosion resistance, and customizable properties. This s...

Abstract Currently, transplanting mechanisms for dryland plug seedlings in China are mainly semiautomatic and have low efficiency. The rotary seedling pick-up mechanism with a planetary gear train for non-uniform intermi...

This paper presents the design and experimental validation of a two-dimensional (2-D) circularly cylindrical phased array antenna with integrated wide-angle beam-switching capability for multibeam radiation in the Ku-ban...

We report synthesis and photophysical studies of spirorhodamines (SRA) with amide N-aliphatic substituents, including measurements of single-crystal X-ray structures, fluorescence emission, and quantum mechanical calcula...

Combustion lies at the heart of gas turbine technology. The combustor is the power source that aids the acceleration of flight. It provides the core functionality of adding heat through the controlled burn of the air-fue...

Abstract A novel method was proposed to design the structure of a bone tissue engineering scaffold based on triply periodic minimal surface. In this method, reverse engineering software was used to reconstruct the surfac...

Abstract Soft electronic devices require durability to endure their inherent exposure to diverse mechanical deformations, including scratches, punctures, and repeated bending. Without intrinsic damage recovery mechanisms...

Abstract The advancement and development of medical surgical robots have provided new technological support for brain surgery and neurosurgical procedures, improving the reliability of highly complex and precise surgerie...

Abstract The synchronizer is a key component of automatic mechanical transmission (AMT) equipped in electric vehicles, but the inertial lock-ring synchronizer (ILRS) commonly used there is not suitable especially for pur...

Rational protein design has successfully enhanced the mechanical stability of biomaterials by optimizing the internal topology of force-bearing domains. However, current design strategies predominantly focus on isolated ...

Abstract The design of multi-principal element alloys (MPEAs) is challenged by data scarcity and the complexity of optimizing multiple mechanical properties simultaneously. To address these challenges, we investigate an ...

In order to study the earthquake seismic behaviors of ecological bags-reinforced wall, the large-scale shaking table model tests are performed. It is shown that the frequency decreases and the damping ratio increases wit...

Abstract Accurate prediction of invasive mechanical ventilation (IMV) requirement in patients with community-acquired pneumonia (CAP) is a key clinical challenge. Conventional static risk stratification scores have limit...
