Haptic Perception via the Dynamics of a Flexible Body Inspired by an Ostrich's Neck
Advanced Intelligent Systems, EarlyView.Inspired by avian anatomy, this study uses a flexible robotic neck to investigate haptic perception driven by musculoskeletal dynamics. By applying physical reservoir computing, the robot encodes external force interactions into its body dynamics, allowing effective object classification.

A quantum reduction to spherical symmetry in loop quantum gravity
Physics Letters B, 2015 Based on a recent purely geometric construction of observables for the spatial diffeomorphism constraint, we propose two distinct quantum reductions to spherical symmetry within full 3+1-dimensional loop quantum gravity.

Fully Integrated Silicone Electromagnetic Actuators for Untethered and Bio‐Inspired Soft Robotics
Advanced Intelligent Systems, EarlyView.GA: A new class of soft electromagnetic actuators, with embedded coils and magnets, is here presented to enhance portability and usability outside structured environments. These actuators, fabricated through a custom additive manufacturing‐assisted process, offer high responsiveness, energy efficiency, and stretchability.

Advanced Intelligent Systems, EarlyView.This article describes the integration of compliant bi‐stability in continuum robots. This integration leads to two variants of compliant bistable mechanism (CBM) integrated continuum robot segments, extending and locking. Results show that when used together, these CBM‐integrated segments allow the continuum robot to form custom shapes.

Quantization of Midisuperspace Models
Living Reviews in Relativity, 2010 We give a comprehensive review of the quantization of midisuperspace models. Though the main focus of the paper is on quantum aspects, we also provide an introduction to several classical points related to the definition of these models.
