Compliant Pneumatic Feet with Real‐Time Stiffness Adaptation for Humanoid Locomotion

Advanced Robotics Research, EarlyView.
A compliant pneumatic foot with real‐time variable stiffness enables humanoid robots to adapt to changing terrains. Using onboard vision and pressure control, the foot modulates stiffness within each gait cycle, reducing impact forces and improving balance. The design, cast in soft silicone with embedded air chambers and Kevlar wrapping, offers durable,

Numerical Analysis of Aerodynamic Interference of Two Passing Cylindrical Bodies at Supersonic Speeds [PDF]

مکانیک هوافضا, 2023
Aerodynamic interference is one of the phenomena that occurs when two flying objects pass near each other. In this case, the change in the pressure distribution on objects passing near each other causes a change in the aerodynamic forces.

UC Food Waste: A Multimodal Robotic Perception Dataset for Robust Contaminant Detection in Complex Biowaste Scenes

Advanced Robotics Research, EarlyView.
A balanced multimodal food‐waste dataset and a novel Split Spatial‐Spectral Attention fusion framework are presented for robotic contaminant detection. Separate processing of RGB, thermal, and multispectral inputs preserves subtle material signatures before feature integration, reducing modality interference and improving classification and ...

XeraBorg: Neural Control of Tail‐Flick Escape for Backward Propulsion in Cyborg Crayfish

Advanced Robotics Research, EarlyView.
This work presents the first controlled tail‐flick propulsion method for the cyborg Cherax quadricarinatus. Comprehensive experiments establish a foundational framework for using the crayfish's natural escape mechanism as a locomotion strategy, expanding its potential as an underwater and amphibious mobile robot.

Electron Acceleration by Multiple Fast Fermi Reflections at Earth’s Bow Shock

The Astrophysical Journal
The generation of energetic particles in the Universe is an important topic in astrophysical and space physics. Although the diffusive shock acceleration has been acknowledged to play an essential role in particle acceleration, the injection problem has ...

Electron Beam Measurements of Density in Shock Waves Reflecting From a Cold Wall [PDF]

, 1968
The normal shock wave is a rarefied-gas flow in which large departures from thermodynamic equilibrium and strong non-linearities occur and it is the simplest such flow due to its one-dimensionality and the absence of solid boundaries.

Microscale Mapping of Fiber Strain and Damage in Composite Wrinkled Laminates Using Computed Tomography Assisted Wide‐Angle X‐Ray Scattering

Advanced Science, EarlyView.
This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

A Soft, Flexible Implant for Wireless Photothermal–Pyroelectric Neurostimulation

Advanced Science, EarlyView.
A replication strategy is used to enlarge the exposed surface area of barium titanate within flexible films with embedded carbon nanotubes, enabling efficient photothermal‐pyroelectric stimulation. Polar crystalline nanosheets show superior performance in guiding neural progenitor cells toward neuronal differentiation.

CNTN2 Deficiency Disrupts Ascending Auditory Neuroglial Interactions and Redox Homeostasis in Neural Presbycusis

Advanced Science, EarlyView.
. ABSTRACT Neural presbycusis disrupts auditory timing and speech perception, yet its molecular basis remains poorly understood. This study identifies Cntn2 as the Ranvier's nodal molecule significantly downregulated in aged auditory nerves. Cntn2 heterozygous knockout (Cntn2+/−) mice showed elevated auditory brainstem response thresholds and prolonged
