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,

Combined effects of singular attractive and asymptotically linear terms in Kirchhoff equations

Electronic Journal of Qualitative Theory of Differential Equations
In this paper, we consider the following Kirchhoff Dirichlet problem with singular attractive term \begin{equation*} \left\{ \begin{aligned} &-\left(a+b\int_{\Omega}|\nabla u|^{2}dx\right)\Delta u=u^{-\gamma}+\lambda f(u) && \text{in}\ \Omega,

Linearizing and Forecasting: A Reservoir Computing Route to Digital Twins of the Brain

Advanced Science, EarlyView.
A new approach uses simple neural networks to create digital twins of brain activity, capturing how different patterns unfold over time. The method generates and recovers key dynamics even from noisy data. When applied to fMRI, it predicts brain signals and reveals distinctive activity patterns across regions and individuals, opening possibilities for ...
