CARAT: Contrastive Feature Reconstruction and Aggregation for Multi-modal Multi-label Emotion Recognition

Posted by dbos UCAS

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 […]

Secret extraction attacks against obfuscated IQP circuits

Posted by dbos UCSB

Kavli Affiliate: David Gross | First 5 Authors: David Gross, Dominik Hangleiter, , , | Summary: Quantum computing devices can now perform sampling tasks which, according to complexity-theoretic and numerical evidence, are beyond the reach of classical computers. This raises the question of how one can efficiently verify that a quantum computer operating in this […]

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

Posted by dbos Tokyo

Kavli Affiliate: Tom Melia | First 5 Authors: Weiguang Cao, Xiaochuan Lu, 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 […]

Spectrum Degeneracies from Quantum Evanescence

Posted by dbos Tokyo

Kavli Affiliate: Tom Melia | First 5 Authors: Weiguang Cao, Xiaochuan Lu, Tom Melia, , | Summary: We identify degeneracies in the energy spectra of quantum theories that occur at integer values of the continuous parameter $N$ of an analytically continued global $O(N)$ symmetry. The degeneracies are enforced by the requirement that evanescent states fall […]

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

Posted by dbos MIT

Kavli Affiliate: Ronald A. Remillard | First 5 Authors: Niek Bollemeijer, Phil Uttley, Arkadip Basak, Adam Ingram, Jakob van den Eijnden | 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 […]

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

Posted by dbos MIT

Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Piyanat Kittiwisit, Steven G. Murray, Hugh Garsden, Philip Bull, Christopher Cain | 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 […]

Axion-Like Particle Detection in Alkali-Noble-Gas Haloscopes

Posted by dbos Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Xiaofei Huang, Xiaolin Ma, Lei Cong, Wei Ji, Jia Liu | Summary: Revealing the essence of dark matter (DM) and dark energy is essential for understanding our universe. Ultralight (rest energy $<$10 eV) bosonic particles, including pseudoscalar axions and axion-like particles (ALPs) have emerged among leading candidates […]
