Brain‐Mimetic Mapless Navigation Framework Integrating Visual Streams and Entorhinal‐Hippocampal‐Prefrontal Circuits

ABSTRACT Efficient autonomous navigation in complex and unstructured environments without pre‐existing maps remains a significant challenge for mobile robotics. Drawing inspiration from rodent neural architectures, this study proposes a brain‐mimetic mapless navigation framework...

Study on the influence of stiffness-to- gravity ratio on the seismic performance of base-isolated high-rise building structures

Base isolation can effectively improve the seismic performance and earthquake safety reserve of structures. However, when it is applied to buildings with large aspect ratios, there are two main problems: isolation effectiveness and overturning resistance. This paper discusses and...

Machining feasibility comparison of homogeneous SiC and SiCf/SiC, Cf/SiC and CFRP composites processed by a green-light femtosecond laser

Purpose Continuous fiber-reinforced polymer or ceramic matrix composites are advanced materials and have been widely used and developed rapidly in the aerospace and automotive industries. However, their excellent mechanical performance causes severe tool wear and poor machining q...

Enhanced Pigeon-Inspired Optimization-Based Active Disturbance Rejection Control for Carrier-Based Aircraft Landing Direct Lift Control

Carrier-based aircraft landing is a critical element in generating aircraft carrier combat capability. Traditional landing control suffers from inherent drawbacks including strong trajectory–attitude coupling, high pilot workload, and insufficient disturbance rejection in complex...

Disuse enhances cancellous and cortical bone responses to mechanical loading by altering lacunocanalicular fluid dynamics

Disuse conditions, such as microgravity, prolonged bed rest, sedentary lifestyle, and limb immobilization, frequently affect human skeletal responses to mechanical loading. However, the precise impact of disuse on bone adaptation to mechanical loading and its underlying mechanobi...

Interface Contact Optimization via Phosphomolybdic Acid Enables 24.9% Efficiency in MoOX-Based Silicon Solar Cells

Abstract The development of cost-effective carrier-selective passivating contacts is critical for enhancing the commercial feasibility of silicon compound solar cells. Molybdenum oxide (MoO X ) has garnered considerable interest as a promising hole transport layer (HTLs). A key a...
