Self-weight and seismic instability of a Qin Terracotta Army horse using finite element analysis

This study utilizes finite element analysis on a 3D-scanned model of a Qin Terracotta Army horse to demonstrate that while self-weight and frequent earthquakes cause minimal damage, rare earthquakes induce global sliding and overturning instability, with friction and ground motion type significantly influencing the response but shell thickness variations having negligible impact on the dominant failure modes.

Infrared Transparency as a Discriminative Signal and Task-Specific Spectral Ranges for Ink and Substrate Analysis in Historical Manuscripts

This study demonstrates that infrared transparency serves as a key discriminative signal for historical manuscript analysis, revealing that short-wave infrared ranges are far more effective than visible light for ink discrimination while substrate characterization remains robust across all spectral bands, thereby supporting task-specific selection of spectral coverage.

Stability analysis of a delayed tuned mass system with hysteretic damping

This paper investigates the dynamic behavior and stability of a delayed tuned mass damper with hysteretic damping by employing an asymmetric scalable hysteresis model and Galerkin projection to analyze the coupled effects of time delay and nonlinear energy dissipation, ultimately revealing critical stability thresholds for improved engineering design.

Effect of Micro-Slats on Airfoil Lift and Stall Behavior

This study demonstrates that passive, curved leading-edge micro-slats optimized via a Digital Twin methodology significantly enhance UAV aerodynamic performance by increasing peak lift by 14.8%, delaying stall to a higher angle of attack, and converting violent stall behavior into a gentle, predictable plateau.

Haptic Virtual Palpation of Volumetric CT: A Density-to-Force Rendering Method andIts Technical Characterisation

This paper presents and characterizes a Unity-based haptic rendering method that converts CT Hounsfield units into force feedback, demonstrating that while interactive discrimination between soft and firm tissues is feasible, the system's ability to distinguish between denser tissue classes is currently limited by conservative force clamping rather than the underlying mapping algorithm.

Grey-Wolf-Optimized Obstacle-Aware Affine Formation Control for Quadrotor Swarms in Cluttered Three-Dimensional Space

This paper proposes a grey-wolf-optimized obstacle-aware affine formation control method for quadrotor swarms in cluttered 3D environments, which dynamically tunes controller gains and influence radii to balance formation tracking accuracy, obstacle clearance, and control effort while ensuring stability and collision avoidance.
