Source Effects in Higher‐Order Ambient Seismic Field Correlations

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Ambient seismic noise interferometry is widely used for surface wave imaging. It typically requires synchronous station recordings and assumes uniform noise source distributions. Higher‐order correlations, such as the re‐correlation of the reconstructed direct waves C2 $\left({C}_{2}\right)$, enable imaging with asynchronous data and can ...

Early Musical Predictions in the Brain as Indexed by the Mismatch Negativity—From Acoustic Deviants to Cognitive Musical Errors

European Journal of Neuroscience, Volume 64, Issue 5, September 2026.
Over the past two decades, ecologically valid music paradigms have shown that mismatch negativity (MMN) reflects a primitive musical intelligence, indexing hierarchical auditory predictions in music that parallel those observed in speech. MMN captures processing from early sensory detection in superior temporal cortices to higher order frontal ...

Complex-valued symmetric radial basis function network for beamforming

, 2009
The complex-valued radial basis function (RBF) network proposed by Chen et al. (1994) has found many applications for processing complex-valued signals, in particular, for communication channel equalization and signal detection.

Genetic Algorithm Assisted Error Probability Optimisation for Beamforming

, 2004
A novel Genetic Algorithm (GA) assisted direct error probability optimisation technique is proposed for adaptive beamforming, which reduces the achievable error probability by nearly two orders of magnitude at a signal-to-noise ratio of 10dB in the ...
