Optoelectronic memristors have emerged as promising hardware platforms for highly efficient image perception owing to their low crosstalk, fast response, and low power consumption. However, the development of optoelectronic memristors with multi-wavelength recognition capabilities remains constrained by the limitations of their inherent bandgap. In this work, a multi-wavelength-modulated optoelectronic memristor that operates based on the localized surface plasmon resonance effect is developed using silver（Ag）-titanium dioxide（TiO2）/polymethyl methacrylate（PMMA） nanocomposites. The SET voltage can be gradually reduced by modulating the optical wavelength of visible irradiation. On this basis, reconfigurable IMP and False logic operations have been implemented in the memristive logic circuit. The neuromorphic visual preprocessing and recognition function for mixed-color patterns is demonstrated based on wavelength-dependent resistive switching behaviors. The proposed optoelectronic memristor enables high-density storage and in-memory computing.

Developing a heterostructure for alloying-based anode for sodium-ion batteries（SIBs） is an efficient solution to accommodate volume change upon sodiation/desodiation and boost sodium storage since it combines the merits of each component. Herein, we report a metallic and microphone-like Sn-Zn0.9Mn0.1O heterostructure via an in-situ Mn doping strategy. Based on theoretical calculations and experimental results, the introduction of Mn into Zn O（a small amount of Mn also diffuses into the Sn lattice） can not only enhance intrinsic electronic conductivity but also reduce the Na+diffusion barrier inside the Sn phase. When evaluated as anode for SIBs, the obtained heterostructures show a high reversible capacity of 395.1 mAh/g at 0.1 A/g, rate capability of 332 mAh/g at 5 A/g, and capacity retention of almost 100%after 850 cycles at 5 A/g, indicating its great potential for high-power application of SIBs.

This paper addresses the verification of strong currentstate opacity with respect to real-time observations generated from a discrete-event system that is modeled with time labeled Petri nets. The standard current-state opacity cannot completely characterize higher-level security. To ensure the higher-level security requirements of a time-dependent system, we propose a strong version of opacity known as strong current-state opacity. For any path(state-event sequence with time information)π derived from a real-time observation that ends at a secret state, the strong current-state opacity of the real-time observation signifies that there is a non-secret path with the same real-time observation as π. We propose general and non-secret state class graphs, which characterize the general and non-secret states of time-dependent systems, respectively. To capture the observable behavior of non-secret states, a non-secret observer is ***, we develop a structure called a real-time concurrent verifier to verify the strong current-state opacity of time labeled Petri nets. This approach is efficient since the real-time concurrent verifier can be constructed by solving a certain number of linear programming problems.
