Nature‐Inspired Janus Actuators with Structurally Engineered PEDOT:PSS

Small, Volume 22, Issue 2, 8 January 2026.
Nature‐inspired PEDOT:PSS Janus actuators are fabricated through a dual solvent‐acid treatment that induces asymmetric conductivity and hydrophobicity within a unified structure. The actuator demonstrates large, reversible bending (3 cm−1) under low voltage (4 V), heat, and vapor stimuli, with minimal Joule heating and excellent cyclic durability ...

Secure Switch-and-Stay Combining (SSSC) for Cognitive Relay Networks [PDF]

IEEE Transactions on Communications, 2016
In this paper, we study a two-phase underlay cognitive relay network, where there exists an eavesdropper who can overhear the message. The secure data transmission from the secondary source to secondary destination is assisted by two decode-and-forward (DF) relays.

Value‐Based Reinforcement Learning for Inter‐Area Oscillations Mitigation in PV‐Integrated Power Systems

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
Enhanced critic‐only DQN with smoothing enables continuous SVC control for damping inter‐area oscillations. The state selection via participation and residue analysis captures critical key modes. Orthogonal array efficiently tunes hyperparameters with low cost.

A Two‐Stage Transient Current Differential Protection Method Considering Fault Inception Angle

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
To address the performance degradation of conventional protection in renewable‐rich power systems, this paper proposes a novel two‐stage transient current differential protection method that accounts for the fault inception angle. As illustrated in the graphical flowchart, the scheme adaptively adjusts the analysis time‐window based on real‐time ...

Intelligent Impedance‐Based SSR Mitigation in Photovoltaic Systems via Genetic Algorithm Optimization

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
This paper proposes a novel impedance‐based approach for mitigating sub‐synchronous resonance (SSR) in grid‐connected photovoltaic systems. A supplementary virtual impedance controller, optimized using a genetic algorithm, is designed to adaptively damp SSR under varying operating conditions, with performance validated through eigenvalue, impedance ...
