Integration of high-performance compact interferometric sensors in a suspended interferometer

Posted by dbos Cornell

Kavli Affiliate: Johannes Lehmann | First 5 Authors: Alexandra Mitchell, Johannes Lehmann, Philip Koch, Samuel Cooper, Jesse van Dongen | Summary: Homodyne Quadrature Interferometers (HoQIs) are compact, low noise and high dynamic range displacement sensors designed for use in gravitational wave observatories. Their lower noise compared to the displacement sensors used at present makes them […]

Modeling ALMA Observations of the Warped Molecular Gas Disk in the Red Nugget Relic Galaxy NGC 384

Posted by dbos Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Jonathan H. Cohn, Maeve Curliss, Jonelle L. Walsh, Kyle M. Kabasares, Benjamin D. Boizelle | Summary: We present 0$.!!^{primeprime}{22}$-resolution CO(2$-$1) observations of the circumnuclear gas disk in the local compact galaxy NGC 384 with the Atacama Large Millimeter/submillimeter Array (ALMA). While the majority of the disk […]

Rhythmic Foley: A Framework For Seamless Audio-Visual Alignment In Video-to-Audio Synthesis

Posted by dbos Cornell

Kavli Affiliate: Dan Luo | First 5 Authors: Zhiqi Huang, Dan Luo, Jun Wang, Huan Liao, Zhiheng Li | Summary: Our research introduces an innovative framework for video-to-audio synthesis, which solves the problems of audio-video desynchronization and semantic loss in the audio. By incorporating a semantic alignment adapter and a temporal synchronization adapter, our method […]

Rigidity transitions in anisotropic networks happen in multiple steps

Posted by dbos Cornell

Kavli Affiliate: Itai Cohen | First 5 Authors: William Y. Wang, Stephen J. Thornton, Bulbul Chakraborty, Anna Barth, Navneet Singh | Summary: We study how the rigidity transition in a triangular lattice changes as a function of anisotropy by preferentially filling bonds on the lattice in one direction. We discover that the onset of rigidity […]

Simulating a quasiparticle on a quantum device

Posted by dbos UCSB

Kavli Affiliate: Leon Balents | First 5 Authors: Rimika Jaiswal, Izabella Lovas, Leon Balents, , | Summary: We propose a variational approach to explore quasiparticle excitations in interacting quantum many-body systems, motivated by the potential in leveraging near-term noisy intermediate scale quantum devices for quantum state preparation. By exploiting translation invariance and potentially other abelian […]

The fallibility of equipartition magnetic field strengths from synchrotron emission using synthetically observed galaxies

Posted by dbos Stanford

Kavli Affiliate: Susan E. Clark | First 5 Authors: Tara Dacunha, Sergio Martin-Alvarez, Susan E. Clark, Enrique Lopez-Rodriguez, | Summary: Understanding the role that magnetic fields play on the stage of galaxy formation requires accurate methods for inferring the properties of extragalactic magnetic fields. Radio synchrotron emission has been the most promising avenue to infer […]

Multiple and subject-specific roles of uncertainty in reward-guided decision-making

Posted by dbos UCSD / Salk

Kavli Affiliate: Angela Yu | Authors: Alexander Paunov, Maëva L’Hôtellier, Zoe He, Dalin Guo, Angela Yu and Florent Meyniel | Summary: Decision-making in noisy, changing, and partially observable environments entails a basic tradeoff between immediate reward and longer-term information gain, known as the exploration-exploitation dilemma. Computationally, an effective way to balance this tradeoff is by […]
