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 […]
Kavli Affiliate: Feng Wang | First 5 Authors: Yuhong Zhang, Yuhong Zhang, , , | Summary: Animation colorization plays a vital role in animation production, yet existing methods struggle to achieve color accuracy and temporal consistency. To address these challenges, we propose textbfAnimeColor, a novel reference-based animation colorization framework leveraging Diffusion Transformers (DiT). Our approach […]
Kavli Affiliate: David T. Limmer | First 5 Authors: Jafar Farhadi, Jafar Farhadi, , , | Summary: We evaluate the exponentially rare fluctuations of the ionic current for a dilute electrolyte by means of macroscopic fluctuation theory. We consider the fluctuating hydrodynamics of a fluid electrolyte described by a stochastic Poisson-Nernst-Planck equation. We derive the […]
Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Feng Wang, , , | Summary: As one of the major challenges for the conservative smoothed particle hydrodynamics (SPH) method, the zero-order consistency issue, although thought to be mitigated by the particle regularization scheme, such as the transport velocity formulation, significantly damps the flow in […]
Kavli Affiliate: Wei Gao | First 5 Authors: Jihong Huang, Jihong Huang, , , | Summary: Direct Position Estimation (DPE) is a method that directly estimate position, velocity, and time (PVT) information from cross ambiguity function (CAF) of the GNSS signals, significantly enhancing receiver robustness in urban environments. However, there is still a lack of […]
Kavli Affiliate: Kerry Vahala | First 5 Authors: Qing-Xin Ji, Qing-Xin Ji, , , | Summary: In microcombs, solitons can drive non-soliton-forming modes to induce optical gain. Under specific conditions, a regenerative secondary temporal pulse coinciding in time and space with the exciting soliton pulse will form at a new spectral location. A mechanism involving […]
Kavli Affiliate: David A. Muller | First 5 Authors: Christian K. Belardi, Christian K. Belardi, , , | Summary: Multislice electron ptychography (MEP) is an inverse imaging technique that computationally reconstructs the highest-resolution images of atomic crystal structures from diffraction patterns. Available algorithms often solve this inverse problem iteratively but are both time consuming and […]
Kavli Affiliate: Gary A. Steele | First 5 Authors: Roudy Hanna, Roudy Hanna, , , | Summary: Improvements in circuit design and more recently in materials and surface cleaning have contributed to a rapid development of coherent superconducting qubits. However, organic resists commonly used for shadow evaporation of Josephson junctions (JJs) pose limitations due to […]

Kavli Affiliate: Xiang Zhang | First 5 Authors: Kuo-Cheng Wu, Kuo-Cheng Wu, , , | Summary: Super-resolution (SR) advances astronomical imaging by enabling cost-effective high-resolution capture, crucial for detecting faraway celestial objects and precise structural analysis. However, existing datasets for astronomical SR (ASR) exhibit three critical limitations: flux inconsistency, object-crop setting, and insufficient data diversity, […]
