Robust representation and non-linear spectral integration of simple and complex harmonic sounds in layers 4 and 2/3 of primary auditory cortex

Posted by dbos Hopkins, This Week: Neuroscience

Kavli Affiliate: Patrick Kanold | Authors: Yunru Chen, Chih-Ting Chen, Yuhan Gui and Patrick O Kanold | Summary: Sound harmonicity is foundational in complex auditory stimuli like music and vocalizations but it remains unclear how such spectrally complex stimuli are processed in the auditory cortex (ACtx). Subregions of the auditory cortex process are thought to […]

Prospects for EMRI/MBH parameter estimation using Quasi-Periodic Eruption timings: short-timescale analysis

Posted by klaurent MIT, This Week: Astrophysics

Kavli Affiliate: Scott A. Hughes | First 5 Authors: Joheen Chakraborty, Joheen Chakraborty, , , | Summary: Quasi-Periodic Eruptions (QPEs) are luminous, recurring X-ray outbursts from galactic nuclei, with timescales of hours to days. While their origin remains uncertain, leading models invoke accretion disk instabilities or the interaction of a massive black hole (MBH) with […]

Experimental validation of photonic lantern imaging and wavefront sensing performance

Posted by klaurent Stanford, This Week: Astrophysics

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Aditya R. Sengupta, Aditya R. Sengupta, , , | Summary: Photonic lanterns (PLs) are fiber-based waveguides that are capable of focal-plane wavefront sensing while simultaneously directing light to downstream science instruments. The optimal choice of wavefront reconstruction algorithm has yet to be determined, and likely depends on […]

The Dolbeault geometric Langlands conjecture via limit categories

Posted by klaurent This Week: Astrophysics, Tokyo

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Tudor Pădurariu, Tudor Pădurariu, , , | Summary: We introduce limit categories for cotangent stacks of smooth stacks as an effective version of classical limits of categories of D-modules on them. We develop their general theory and pursue their relation with categories of D-modules. In particular, we […]
