Continuous scanning full-field OCT for fast volumetric imaging of multi-cellular aggregates
Full-field optical coherence tomography (FF-OCT) offers label-free, high-resolution imaging of biological samples but remains limited by slow acquisition due to piezoelectric mirror modulation. We present a continuous-scanning FF-OCT method that eliminates piezoelectric displacement and synchronization by continuously translating the sample with a motorized stage while recording images on the fly. Depth-resolved information is retrieved via Fourier analysis of the temporal signal at each pixel.…

Perceptual Compensation of Ambisonics Recordings for Reproduction in Room
Ambisonics is a method for capturing and rendering a sound field accurately, assuming that the acoustics of the playback room does not significantly influence the sound field. However, in practice, the acoustics of the playback room may lead to a noticeable degradation in sound quality. We propose a recording and rendering method based on Ambisonics that utilizes a perceptually-motivated approach to compensate for the reverberation of the playback room. The recorded direct and reverberant sound…

#NowPlaying Guided by Julian Cope’s “The Modern Antiquarian” and Aurbrey Burl’s “A Guide to the Stone Circles of Britain”, Llyn Y Cwn aka Ben Powell makes abyssal dark ambient soundscapes with site-specific field recordings from Wales and beyond. https://…

Llyn Y Cwn
Llyn Y Cwn is a field recording based dark ambient project with focus on atmosphere, immersion and environment. Ben Powell has been making electronic music since the 90s, drawing inspiration from his native North Wales landscape and his participation on Arctic research cruises. Llyn Y Cwn (Welsh - lake of the dogs) is a small lake at 715m in the Glyder mountain range of Snowdonia, North Wales.

Neural subspaces, minimax entropy, and mean-field theory for networks of neurons
Recent advances in experimental techniques enable the simultaneous recording of activity from thousands of neurons in the brain, presenting both an opportunity and a challenge: to build meaningful, scalable models of large neural populations. Correlations in the brain are typically weak but widespread, suggesting that a mean-field approach might be effective in describing real neural populations, and we explore a hierarchy of maximum entropy models guided by this idea. We begin with models that…

High-Resolution Directional Depth Electrodes: Open-Source FEM Lead-Field Modeling, Characterization, and Validation
Depth electrodes used in stereoelectroencephalography (sEEG) and deep-brain stimulation (DBS) are essential tools for neural recording and stimulation. Traditional designs have limited spatial resolution, typically 8 to 16 cylindrical contacts (0.8 to 1.0 mm diameter) along a 5 to 10 cm shaft, restricting recordings from small or localized populations. Recent high-density, directional electrodes (HDsEEG) enable finer localization of local field potentials (LFPs) and spike timing. Yet, character…
