Observation of Linear and Nonlinear Light Trapping on Topological Dislocations

Laser &Photonics Reviews, EarlyView.
Topological dislocations are global lattice defects found in various systems ranging from crystals to photonic lattices. This work reports the first observation at optical frequencies of linear modes with tunable localization bound to edge dislocations and their nonlinear counterparts ‐ dislocation solitons. These results reveal an intriguing interplay

Synthesis and Characterization of a Cerium(IV) Coordination Polymer Containing Isonicotinic Acid Zwitterions

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The new coordination polymer [Ce4O2(OH)2(NO3)2(C6H5NO2)8](NO3)8 is reported. It was discovered during a ligand screening experiment. Its crystallization was studied in situ via powder X‐ray diffraction and X‐ray absorption near‐edge structure spectroscopy.

Decoding the Self: Single-Trial Prediction of Self-Boundary Meditation States From Magnetoencephalography Recordings. [PDF]

Hum Brain Mapp
Meditation‐induced self‐boundary dissolution can be predicted from magnetoencephalography recordings using Lempel‐Ziv complexity and oscillatory power as neural markers. We demonstrate significantly above‐chance classification of altered self‐experience on a single‐trial basis and show that it is mediated by complex activation patterns across brain ...

Exploring aperiodic order in photonic time crystals

Physical Review Applied
We present a theoretical framework for analyzing aperiodically ordered photonic time quasicrystals (PTQCs), which are the temporal analogs of spatial photonic quasicrystals. Using a general two-symbol substitutional sequence to model temporal modulations, we extend the trace and anti-trace map formalism used for spatial photonic quasicrystals to the ...

Dynamic Neural‐Model‐Based Predictive Control for Autonomous Wheel‐Legged Robot System

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Mobile wheel‐legged robots exhibiting mobility, stability and reliability have garnered heightened research attention in demanding real‐world scenarios, especially in material transport, emergency response and space exploration. The kinematics model merely delineates the geometric relationship of the controlled objective, disregarding force ...
