LP-3DGS: Learning to Prune 3D Gaussian Splatting

Kavli Affiliate: Cheng Peng | First 5 Authors: Zhaoliang Zhang, Tianchen Song, Yongjae Lee, Li Yang, Cheng Peng | Summary: Recently, 3D Gaussian Splatting (3DGS) has become one of the mainstream methodologies for novel view synthesis (NVS) due to its high quality and fast rendering speed. However, as a point-based scene representation, 3DGS potentially generates […]

Self-dispersion-managed adiabatic frequency conversion

Kavli Affiliate: Jeffrey Moses | Summary:Dispersion management of few-cycle pulses is crucial for ultrafast optics and photonics. Often, nontrivial dispersion is compensated using complex optical systems or minimized through careful design of waveguides. Here, we present dispersion-managed adiabatic frequency conversion enabling efficient downconversion of an 11.1-fs near-IR pulse to an 11.6-fs mid-IR pulse spanning an […]

Resistance Distribution of Decoherent Quantum Hall-Superconductor Edges

Kavli Affiliate: Jing Wang | First 5 Authors: Yichen Hu, Jing Wang, Biao Lian, , | Summary: We study the probability distribution of the resistance, or equivalently the charge transmission, of a decoherent quantum Hall-superconductor edge, with the decoherence coming from metallic puddles along the edge. Such metallic puddles may originate from magnetic vortex cores […]

Ultraheavy Ultrahigh-Energy Cosmic Rays

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: B. Theodore Zhang, Kohta Murase, Nick Ekanger, Mukul Bhattacharya, Shunsaku Horiuchi | Summary: We investigate the propagation of ultraheavy (UH) nuclei as ultrahigh-energy cosmic rays (UHECRs). We show that their energy loss lengths at $lesssim300$~EeV are significantly longer than those of protons and intermediate-mass nuclei, and that […]
