Unsupervised learning of two-component nematicity from STM data on magic angle bilayer graphene

Posted by klaurent Caltech

Kavli Affiliate: Stevan Nadj-Perge | Summary:Moiré materials such as magic angle twisted bilayer graphene (MATBG) exhibit remarkable phenomenology, but present significant challenges for certain experimental methods, particularly scanning probes such as scanning tunneling microscopy (STM). Typical STM studies that can image tens of thousands of atomic unit cells can image roughly ten moiré cells, making […]

A Uniform Type Ia Supernova Distance Ladder with the Zwicky Transient Facility: Absolute Calibration Based on the Tip of the Red Giant Branch (TRGB) Method

Posted by Chicago

Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Suhail Dhawan, Ariel Goobar, Joel Johansson, In Sung Jang, Mickael Rigault | Summary: The current Cepheid-calibrated distance ladder measurement of $H_0$ is reported to be in tension with the values inferred from the cosmic microwave background (CMB), assuming standard cosmology. However, some tip of the red […]

In situ architecture of the lipid transport protein VPS13C at ER-lysosomes membrane contacts

Posted by klaurent Yale

Kavli Affiliate: Pietro DeCamilli | Authors: Shujun Cai, Yumei Wu, Andres Guillen-Samander, William F Hancock-Cerutti, Jun Liu and Pietro De Camilli | Summary: VPS13 is a eukaryotic lipid transport protein localized at membrane contact sites. Previous studies suggested that it may transfer lipids between adjacent bilayers by a bridge-like mechanism. Direct evidence for this hypothesis […]

GaitStrip: Gait Recognition via Effective Strip-based Feature Representations and Multi-Level Framework

Posted by klaurent UCAS

Kavli Affiliate: Zheng Zhu | First 5 Authors: Ming Wang, Beibei Lin, Xianda Guo, Lincheng Li, Zheng Zhu | Summary: Many gait recognition methods first partition the human gait into N-parts and then combine them to establish part-based feature representations. Their gait recognition performance is often affected by partitioning strategies, which are empirically chosen in […]

Probing squeezing for gravitational-wave detectors with an audio-band field

Posted by klaurent MIT

Kavli Affiliate: Lisa Barsotti | Summary:Squeezed vacuum states are now employed in gravitational-wave interferometric detectors, enhancing their sensitivity and thus enabling richer astrophysical observations. In future observing runs, the detectors will incorporate a filter cavity to suppress quantum radiation pressure noise using frequency-dependent squeezing. Interferometers employing internal and external cavities decohere and degrade squeezing in […]

Towards performant and reliable undersampled MR reconstruction via diffusion model sampling

Posted by klaurent UCAS

Kavli Affiliate: Cheng Peng | First 5 Authors: Cheng Peng, Pengfei Guo, S. Kevin Zhou, Vishal Patel, Rama Chellappa | Summary: Magnetic Resonance (MR) image reconstruction from under-sampled acquisition promises faster scanning time. To this end, current State-of-The-Art (SoTA) approaches leverage deep neural networks and supervised training to learn a recovery model. While these approaches […]
