Anisotropic Second‐ and Third‐Harmonic Hermite–Gaussian Beam Generation with NbOI2 Holograms
Advanced Photonics Research, EarlyView.Anisotropic second‐ and third‐harmonic Hermite–Gaussian (HG) beam generation is demonstrated with ultrathin NbOI2 grating holograms to produce the nonlinear HG01 and HG10 modes with high anisotropy ratios. The relative magnitudes of the second‐ and third‐order nonlinear susceptibility tensor elements of NbOI2 crystal are extracted. These demonstrations

Advanced Robotics Research, EarlyView.A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...

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 Theory and Simulations, EarlyView.This study develops a superconvergent meshless method to analyze and control vibrations in twisted, bidirectional functionally graded Terfenol‐D beams. By optimizing magnetostrictive patch placement, it demonstrates effective vibration suppression under dynamic loads, highlighting the design potential of strategically graded materials in complex ...

, 2019 We study the number of connected graphs with $n$ vertices that cannot be written as the cartesian product of two graphs with fewer vertices. We give an upper bound which implies that for large $n$ almost all graphs are both connected and cartesian prime.

Observation of Localized Resonant Phonon Polaritons in Biaxial α‐MoO3 Nanoparticles
Advanced Science, EarlyView.Biaxial α‐MoO3 nanoparticles exhibit tunable, high‐Q mid‐infrared resonances driven by localized phonon polaritons. Combining a novel synthesis method, hyperspectral near‐field imaging and a unified theoretical analysis, this work reveals eigenmodes and resonance conditions in biaxial particles.
