Discovery of Quasi-periodic Eruptions in the Tidal Disruption Event and Extreme Coronal Line Emitter AT2022upj: implications for the QPE/TDE fraction and a connection to ECLEs

Posted by dbos March 24, 2025MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Joheen Chakraborty, Erin Kara, Riccardo Arcodia, Johannes Buchner, Margherita Giustini | Summary: Quasi-periodic eruptions (QPEs) are recurring soft X-ray transients emerging from the vicinity of supermassive black holes (SMBHs) in nearby, low-mass galaxy nuclei; about ten QPE hosts have been identified thus far. Here we report the […]

Effective field theory for triple-Q magnetic orders on a hexagonal lattice

Posted by klaurent March 24, 2025UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Jin-Tao Jin, Yi Zhou, , , | Summary: We develop a comprehensive Ginzburg-Landau theory describing triple-Q magnetic orders on hexagonal lattices, focusing on $O(N)$ models with $N=2$ and $N=3$. Through systematic analysis of symmetry-allowed terms in the free energy, we establish complete phase diagrams governed by competing […]

ReconDreamer++: Harmonizing Generative and Reconstructive Models for Driving Scene Representation

Posted by klaurent March 24, 2025UCAS

Kavli Affiliate: Zheng Zhu | First 5 Authors: Guosheng Zhao, Guosheng Zhao, , , | Summary: Combining reconstruction models with generative models has emerged as a promising paradigm for closed-loop simulation in autonomous driving. For example, ReconDreamer has demonstrated remarkable success in rendering large-scale maneuvers. However, a significant gap remains between the generated data and […]

A Promising Method for Strongly Correlated Electrons in Two Dimensions: Gutzwiller-Guided Density Matrix Renormalization Group

Posted by dbos March 24, 2025March 31, 2025UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Hui-Ke Jin, Rong-Yang Sun, Hong-Hao Tu, Yi Zhou, | Summary: The study of strongly correlated electron systems remains a fundamental challenge in condensed matter physics, particularly in two-dimensional (2D) systems hosting various exotic phases of matter including quantum spin liquids, unconventional superconductivity, and topological orders. Although Density […]

NMPC-based Unified Posture Manipulation and Thrust Vectoring for Fault Recovery

Posted by klaurent March 24, 2025Caltech

Kavli Affiliate: Morteza Gharib| Summary:Multi-rotors face significant risks, as actuator failures at high altitudes can easily result in a crash and the robot’s destruction. Therefore, rapid fault recovery in the event of an actuator failure is necessary for the fault-tolerant and safe operation of unmanned aerial robots. In this work, we present a fault recovery […]

Deciphering the Origins of the Elements Through Galactic Archeology

Posted by klaurent March 23, 2025MIT

Kavli Affiliate: Anna Frebel | Summary:Low-metallicity stars preserve the signatures of the first stellar nucleosynthesis events in the Galaxy, as their surface abundances reflect the composition of the interstellar medium from which they were born. Aside from primordial Big Bang nucleosynthesis, massive stars, due to their short lifetimes, dominate the ejecta into the interstellar medium […]

CellBouncer, A Unified Toolkit for Single-Cell Demultiplexing and Ambient RNA Analysis, Reveals Hominid Mitochondrial Incompatibilities

Posted by dbos March 23, 2025March 31, 2025UCSF

Kavli Affiliate: Alex Pollen | Authors: Nathan K Schaefer, Bryan J Pavlovic and Alex Aaron Pollen | Summary: Pooled processing, in which cells from multiple sources are cultured or captured together, is an increasingly popular strategy for droplet-based single cell sequencing studies. This design allows efficient scaling of experiments, isolation of cell-intrinsic differences, and mitigation […]

Predicting performance-related properties of refrigerant based on tailored small-molecule functional group contribution

Posted by dbos March 23, 2025March 31, 2025Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Peilin Cao, Ying Geng, Nan Feng, Xiang Zhang, Zhiwen Qi | Summary: As current group contribution (GC) methods are mostly proposed for a wide size-range of molecules, applying them to property prediction of small refrigerant molecules could lead to unacceptable errors. In this sense, for the design […]
