Acute Neuropixels recordings in the marmoset monkey

Kavli Affiliate: John Reynolds | Authors: Nicholas M Dotson, Zachary W Davis, Patrick Jendritza and John H Reynolds | Summary: High-density linear probes, like Neuropixels, provide an unprecedented opportunity to understand how neural populations within specific laminar compartments contribute to behavior. Marmoset monkeys, unlike macaque monkeys, have a lissencephalic (smooth) cortex that enables recording perpendicular […]

CARAT: Contrastive Feature Reconstruction and Aggregation for Multi-Modal Multi-Label Emotion Recognition

Kavli Affiliate: Cheng Peng | First 5 Authors: Cheng Peng, Ke Chen, Lidan Shou, Gang Chen, | Summary: Multi-modal multi-label emotion recognition (MMER) aims to identify relevant emotions from multiple modalities. The challenge of MMER is how to effectively capture discriminative features for multiple labels from heterogeneous data. Recent studies are mainly devoted to exploring […]

Constraints on the spectrum of field theories with non-integer $O(N)$ symmetry from quantum evanescence

Kavli Affiliate: Tom Melia | Summary:We identify constraints in the energy spectra of quantum theories that have a global $O(N)$ symmetry, where $N$ is treated as a continuous parameter. We point out that a class of evanescent states fall out of the spectrum at integer values of $N$ in pairs, via an annihilation mechanism. This […]

Evidence for a dynamic corona in the short-term time lags of black hole X-ray binary MAXI J1820+070

Kavli Affiliate: Ronald Remillard | Summary:In X-ray observations of hard state black hole X-ray binaries, rapid variations in accretion disc and coronal power-law emission are correlated and show Fourier-frequency-dependent time lags. On short (~0.1 s) time-scales, these lags are thought to be due to reverberation and therefore may depend strongly on the geometry of the […]

matvis: A matrix-based visibility simulator for fast forward modelling of many-element 21 cm arrays

Kavli Affiliate: Jacqueline Hewitt | Summary:Detection of the faint 21 cm line emission from the Cosmic Dawn and Epoch of Reionisation will require not only exquisite control over instrumental calibration and systematics to achieve the necessary dynamic range of observations but also validation of analysis techniques to demonstrate their statistical properties and signal loss characteristics.
