Almost automorphic solutions for differential equations with piecewise constant argument
, 2014 Using the method of exponential dichotomies, we establish a new existence and uniqueness theorem of almost automorphic solution for differential equations with piecewise constant argument of the form \(x'(t)=A(t)x(t)+B(t)x([t])+f(t), \quad t\in\mathbb{R}

Advanced Intelligent Systems, EarlyView.We developed methods to characterize soft contractile actuators using force–displacement measurements in the passive state and the total force in the active state and define the operational range of thermal, electrothermal, and pneumatic muscles. A graphical method enables the selection of an actuator based on the required mechanical force–displacement

Benchmarking Data‐Driven Control of Octopus‐Inspired Soft Arms in Underwater Environment
Advanced Intelligent Systems, EarlyView.Underwater soft robots present safe, compliant interaction, yet reproducible control remains scarce. This work presents an open benchmark for octopus‐inspired arms: a smooth, velocity‐diverse data‐collection scheme produces a compact dataset to train a vanilla policy.

Thermally Drawn Bioelectric Catheters: Enabling Proprioceptive Endovascular Navigation
Advanced Intelligent Systems, EarlyView.This work introduces a novel bioelectric navigation system eliminates the need for harmful fluoroscopy during endovascular surgeries. A bespoke 16‐electrode catheter is fabricated using rapid thermal drawing and laser micro‐machining. Paired with a real‐time tracking algorithm fusing vascular geometry detection and distance estimation, this technology ...
