Convolutional neural networks are widely used in gesture recognition research, which employs surface electromyography. However, when processing electromyography data, current deep learning models still face challenges, such as insufficient effective feature extraction, poor performance multi-gesture recognition, and low accuracy recognizing sparse To address these issues, this study proposed a multi-stream adaptive convolutional with residual modules (MSACNN-RM) for integrates multiple...

Abstract Time-reversal symmetry (TRS) protection is core to topological physics, yet its role in correlated oxides-typically non-topological-remains underexplored. This limit hampers the potential engineering exotic quantum states by fusing TRS and rich emergent phenomena oxide platform. Here, we report evidence of a TRS-protected subband at oxygen vacancy-free LaAlO3/SrTiO3 interfaces. causes low-field oscillation with anomalous characters: exceptionally light electron mass, aperiodicity,...

The rich electron correlations and highly coherent transport in reconfigurable devices sketched by a conductive atomic force microscope tip at the LaAlO3/SrTiO3 interface have enabled oxide platform an ideal playground for studying correlated electrons quantum technological applications. Why these one-dimensional possess enhanced properties over two-dimensional interface, however, has remained elusive. Here we provide evidence that nanowires are intrinsically ferroelastic domain walls nature...

Chirality in solid-state materials has sparked significant interest due to potential applications of topologically-protected chiral states next-generation information technology. The electrical magneto-chiral effect (eMChE), arising from relativistic spin-orbit interactions, shows great promise for developing and devices electronic integration. Here we demonstrate an angle-resolved eMChE A-B-C-C type atomic-layer superlattice lacking time space inversion symmetry. We observe...
