LLM-optimized wavelet packet transform for synchronous condenser fault prediction.

This paper proposes an innovative approach for predicting faults in synchronous condensers in ultra-high voltage direct current (UHVDC) transmission systems. The framework combines Wavelet Packet Transform (WPT) for intelligent feature extraction with an enhanced Gated Recurrent Unit (GRU) network augmented by multi-head attention mechanisms. WPT is employed for efficient decomposition of fault signals into multiple frequency sub-bands, facilitating the extraction of fault features such as energy, entropy, and statistical moments.

Cyanuric acid in Paramecium secretions is an efficient quorum sensing inducer.

Quorum sensing is a process of bacterial chemical communication via extracellular signal molecules known as autoinducers, allowing synchronized collective behavior changes related to population density. However, the ecological significance of quorum sensing in multi-species communities, particularly coexisting with predators, remains unaddressed. In this study, we discovered that cyanuric acid (CA), a compound secreted by the widespread protozoan Paramecium, significantly influences the LuxR-type quorum sensing in Pseudomonas aeruginosa PAO1.
