Advanced Optical Materials, EarlyView.A theoretical model is developed to visualize three‐dimensional refractive index profiles in transmission holographic gratings. In this work, it is applied to photopolymerizable hydrogels, enabling detailed analysis of the internal structure of recorded holograms and their evolution under different degradation conditions.

An identity of symmetry for the Bernoulli polynomials
Discrete Mathematics, 2008 The author proves an identity of symmetry for the higher Bernoulli polynomials. It turns out implies that the recurrence relation and multiplication theorem for the Bernoulli polynomials discussed by \textit{F. T. Howard} [J. Number Theory 52, No. 1, 157--172 (1995; Zbl 0844.11019)], as well as a relation of symmetry between the power sum polynomials ...

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.

Prime Ideals in Rings Satisfying Polynomial Identities
, 1979 The systematic study of prime ideals in noncommutative rings satisfying polynomial identities lends itself to diverse methods of approach. The geometric method, which we explore at several points of this thesis, was initiated by C. Procesi in the 1960's.

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.
