GaussianPretrain: A Simple Unified 3D Gaussian Representation for Visual Pre-training in Autonomous Driving

Autor: Xu, Shaoqing, Li, Fang, Jiang, Shengyin, Song, Ziying, Liu, Li, Yang, Zhi-xin

Self-supervised learning has made substantial strides in image processing, while visual pre-training for autonomous driving is still in its infancy. Existing methods often focus on learning geometric scene information while neglecting texture or trea

Design of Ligand-Binding Proteins with Atomic Flow Matching

Autor: Liu, Junqi, Li, Shaoning, Shi, Chence, Yang, Zhi, Tang, Jian

Designing novel proteins that bind to small molecules is a long-standing challenge in computational biology, with applications in developing catalysts, biosensors, and more. Current computational methods rely on the assumption that the binding pose o

A Three-Coupled-Channel Analysis of $Z_c(3900)$ Involving $D\bar{D}^*$, $\pi J/\psi$, and $\rho \eta_c $

Autor: Yu, Kang, Wang, Guang-Juan, Wu, Jia-Jun, Yang, Zhi

In this work, we conduct a three-coupled-channel analysis of the $Z_c(3900)$ structure, focusing on the $D\bar{D}^*$, $J/\psi \pi$, and $\rho \eta_c$ channels, based on the one-boson exchange model. Drawing from previous study on the exotic state $T_
