Advanced Robotics Research, EarlyView.Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.

Advanced Robotics Research, EarlyView.This work presents a state‐adaptive Koopman linear quadratic regulator framework for real‐time manipulation of a deformable swab tool in robotic environmental sampling. By combining Koopman linearization, tactile sensing, and centroid‐based force regulation, the system maintains stable contact forces and high coverage across flat and inclined surfaces.

Arbitrary decays for a viscoelastic equation
Boundary Value Problems, 2011 In this paper, we consider the nonlinear viscoelastic equation ∣ u t ∣ ρ u t t - Δ u - Δ u t t + ∫ 0 t g ( t - s ) Δ u ( s ) d s + ∣ u ∣ p u = 0 , in a ...

Exponential and Polynomial Decay Rates of a Porous Elastic System with Thermal Damping
Journal of Function Spaces, 2023 This paper concerns a linear porous thermoelastic system, where the heat conduction is given by Cattaneo’s law. By using the theory of the semigroup of the linear operator, the well-posedness is proven.

On associated polynomials and decay rates for birth–death processes
Journal of Mathematical Analysis and Applications, 2003 Consider a sequence of monic polynomials \(\{P_n(x): n= 0,1,\dots\}\) satisfying the familiar recurrence relation \[ \begin{gathered} P_n(x):= (x- c_n)(P_{n-1}(x)- d_n P_{n-2}(x),\quad n> 1,\\ P_0(x):= 1,\quad P_1(x):= x- c_1,\end{gathered} \] where \(c_n\) is real and \(d_n> 0\).

Polynomial decay of correlations in linked-twist maps [PDF]
Ergodic Theory and Dynamical Systems, 2013 AbstractLinked-twist maps are area-preserving, piecewise diffeomorphisms, defined on a subset of the torus. They are non-uniformly hyperbolic generalizations of the well-known Arnold cat map. We show that a class of canonical examples have polynomial decay of correlations for$\alpha $-Hölder observables, of order$1/ n$.

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,

Advanced Robotics Research, EarlyView.This study explores how information processing is distributed between brains and bodies through a codesign approach. Using the “backpropagation through soft body” framework, brain–body coupling agents are developed and analyzed across several tasks in which output is generated through the agents’ physical dynamics.

Energy decay in thermoelasticity type III with viscoelastic damping and delay term
Electronic Journal of Differential Equations, 2012 In this article, we consider a thermoelastic system of type III with a viscoelastic damping and internal delay. We use the multiplier method to prove, under suitable assumptions, general energy decay results from which the exponential and polynomial ...
