Kavli Affiliate: Joel E. Moore | First 5 Authors: Jyesta M. Adhidewata, Jyesta M. Adhidewata, , , | Summary: The excitations of fractional quantum Hall effect (FQHE) states have been largely inaccessible to experimental probes until recently. New electron scanning tunneling microscopy (STM) results from Hu et.al. (2023) show promise in detecting and identifying these […]
Kavli Affiliate: Wei Gao | First 5 Authors: Kai Liu, Kai Liu, , , | Summary: Universal machine learning interatomic potentials (uMLIPs) are reshaping atomistic simulation as foundation models, delivering near textitab initio accuracy at a fraction of the cost. Yet the lack of reliable, general uncertainty quantification limits their safe, wide-scale use. Here we […]
Kavli Affiliate: Robert Edwards | Authors: Susanna R Grigson, George Bouras, Bhavya Papudeshi, Vijini Mallawaarachchi, Michael J Roach, Przemyslaw Decewicz and Robert A Edwards | Summary: Accurate genome annotation is fundamental to decoding viral diversity and understanding bacteriophage biology; yet, the majority of bacteriophage genes remain functionally uncharacterised. Bacteriophage genomes often exhibit conserved gene order, […]
Kavli Affiliate: David A. Muller | First 5 Authors: Desheng Ma, Desheng Ma, , , | Summary: Contrast transfer mechanisms for electron scattering have been extensively studied in transmission electron microscopy. Here we revisit H. Rose’s generalized contrast formalism from scattering theory to understand where information is encoded in four-dimensional scanning transmission electron microscopy (4D-STEM) […]
Kavli Affiliate: Feng Wang | First 5 Authors: Kimi Team, Kimi Team, , , | Summary: We introduce Kimi K2, a Mixture-of-Experts (MoE) large language model with 32 billion activated parameters and 1 trillion total parameters. We propose the MuonClip optimizer, which improves upon Muon with a novel QK-clip technique to address training instability while […]
