Use of noise correlation matrices to interpret ocean ambient noise
The Journal of the Acoustical Society of America, 2019 Oceanic ambient noise is a dynamic mixture of biologic, geophysical, and anthropogenic sound sources. A goal of research is to put some order in this cacophony of information, understand the received spectral content and determine the primary contributors to the ambient noise.

Wave field inversion of ambient seismic noise
, 2017 We formulate a full wave field inversion for ambient seismic noise recorded by large and dense seismograph arrays. Full wave field inversion exploits the constraints on the gradients of the wave field that array data inherently possess (the sum is ...

B3AM: A beamforming toolbox for three-component ambient seismic noise analysis
SeismicaWe introduce the MATLAB toolbox B3AM for beamforming of three-component ambient noise array data. We explain the theory behind three-component beamforming and polarisation analysis in particular, provide an overview of the workflow, and discuss the ...

Advanced Materials, EarlyView.Vertical organic electrochemical transistors (vOECTs) are limited in speed by ion‐impermeable metal electrodes that slow ion injection. Using ion‐permeable PBFDO top electrodes allows direct vertical ion injection into BBL channels, achieving high current densities (>400 A cm−2), large on/off ratios (>106), and ultrafast switching in 28 µs. This sets a

Advanced Materials, EarlyView.We report a multifunctional tapered optical fiber integrating a conformal micro‐resistance temperature detector (µRTD) for local, real‐time thermometry during optical stimulation. The platform combines light‐delivery and temperature sensing within a minimally invasive footprint, enabling detection of sub‐degree cortical heating under representative ...

Acoustic Ambient Noise of the Cochin backwaters [PDF]
, 1978 75-78Results of weekly field observations over 1 yr on the acoustic ambient noise levels at 3 stations in the Cochin backwaters are presented. The recorded noise are subjected to a 1/3 octave analysis using audio frequency spectrometer and oscilloscope ...

Advanced Materials, EarlyView.We demonstrate a neuromorphic synapse in 2D Fe3GaTe2 flakes. The device operates via a current‐driven transformation from a skyrmion‐lattice to a stripe‐domain state, yielding a linear anomalous Hall resistance response with a tunable slope to enable multiply‐accumulate operations. Simulations confirm its viability in artificial neural networks.

Advanced Materials, EarlyView.A fully flexible ion‐gel‐gated graphene‐channel transistor driven by a triboelectric nanogenerator enables self‐powered tactile sensing and synaptic learning. Mimicking spike‐rate‐dependent plasticity, the device exhibits frequency‐selective potentiation and depression, supporting rate‐coded neuromorphic computation even under flex.
