Body-Hand Modality Expertized Networks with Cross-attention for Fine-grained Skeleton Action Recognition

Posted by klaurent Stanford

Kavli Affiliate: Hsiao-Mei (Sherry) Cho| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:Skeleton-based Human Action Recognition (HAR) is a vital technology in robotics and human-robot interaction. However, most existing methods concentrate primarily on full-body movements and often overlook subtle hand motions that are critical for distinguishing fine-grained actions. Recent work leverages a unified graph […]

Solovay Kitaev Algorithm and Randomized Compilation

Posted by klaurent Stanford

Kavli Affiliate: Susan Clark | Summary:We analyze the use of the Solovay Kitaev (SK) algorithm to generate an ensemble of one qubit rotations over which to perform randomized compilation. We perform simulations to compare the trace distance between the quantum state resulting from an ideal one qubit $R_Z$ rotation and discrete SK decompositions. We find […]

Uncertainty Distillation: Teaching Language Models to Express Semantic Confidence

Posted by klaurent Cornell

Kavli Affiliate: David Muller| First 5 Authors: Sophia Hager, Sophia Hager, , , | Summary:As large language models (LLMs) are increasingly used for factual question-answering, it becomes more important for LLMs to have the capability to communicate the likelihood that their answer is correct. For these verbalized expressions of uncertainty to be meaningful, they should […]

Probing Benchmark Models of Hidden-Sector Dark Matter with DAMIC-M

Posted by klaurent Chicago

Kavli Affiliate: Paolo Privitera | Summary:We report on a search for sub-GeV dark matter (DM) particles interacting with electrons using the DAMIC-M prototype detector at the Modane Underground Laboratory. The data feature a significantly lower detector single $e^-$ rate (factor 50) compared to our previous search, while also accumulating a ten times larger exposure of […]

Flux trapping in NbTiN strips

Posted by klaurent Cornell

Kavli Affiliate: Katja C. Nowack | Summary:We use scanning superconducting quantum interference device (SQUID) microscopy to image individual vortices in superconducting strips fabricated from NbTiN thin films. By repeatedly field-cooling strips of different widths in applied magnetic fields, we extract the threshold field at which the first vortex enters a strip, as well as the […]

The Atacama Cosmology Telescope: DR6 Constraints on Extended Cosmological Models

Posted by klaurent Stanford

Kavli Affiliate: Kent Irwin | Summary:We use new cosmic microwave background (CMB) primary temperature and polarization anisotropy measurements from the Atacama Cosmology Telescope (ACT) Data Release 6 (DR6) to test foundational assumptions of the standard cosmological model and set constraints on extensions to it. We derive constraints from the ACT DR6 power spectra alone, as […]
