RL-accelerated OSQP for real-time asymmetric corotational beam contact simulation in continuum robots

H. S. Chen, Jian Chen, Shuai Wang, Mingcong Chen et autres

The real-time simulation of highly deformable slender structures interacting with complex, irregular boundaries remains a computationally demanding challenge in computational mechanics. A prominent motivating application for this fundamental problem is the navigation of continuum surgical robots within narrow anatomical cavities, which involves …

Learning Patient-Specific Disease Dynamics with Latent Flow Matching for Longitudinal Imaging Generation

H. S. Chen, Rui Yin, Yifan Chen, Qi Chen et autres

Understanding disease progression is a central clinical challenge with direct implications for early diagnosis and personalized treatment. While recent generative approaches have attempted to model progression, key mismatches remain: disease dynamics are inherently continuous and monotonic, yet latent representations are often scattered, …

A Reinforcement Learning Based FEM Solver for Accelerating Contact-Influenced Simulation of Continuum Robots

H. S. Chen, Jian Chen, Zhongkai Zhang, Hongbin Liu

Continuum robots exhibit exceptional flexibility and multi-degree-of-freedom maneuverability, offering significant advantages for navigating confined luminal spaces. However, rapid simulation of their contact-influenced behavior remains challenging. This paper presents RLFEM, an innovative finite element method (FEM) featuring a reinforcement learning-enhanced quadratic programming solver, …

SurfaceSplat: Connecting Surface Reconstruction and Gaussian Splatting

Jia-Wang Bian, Guosheng Lin, H. S. Chen, Chunhua Shen

Surface reconstruction and novel view rendering from sparse-view images are challenging. Signed Distance Function (SDF)-based methods struggle with fine details, while 3D Gaussian Splatting (3DGS)-based approaches lack global geometry coherence. We propose a novel hybrid method that combines the strengths of both …

Tinker: Diffusion's Gift to 3D--Multi-View Consistent Editing From Sparse Inputs without Per-Scene Optimization

Canyu Zhao, Xiaoman Li, Tiancong Feng, H. S. Chen et autres

We introduce Tinker, a versatile framework for high-fidelity 3D editing that operates in both one-shot and few-shot regimes without any per-scene finetuning. Unlike prior techniques that demand extensive per-scene optimization to ensure multi-view consistency or to produce dozens of consistent edited input …

Partial Wave Analysis of $e^{+}e^{-} \rightarrow π^{+}π^{-}J/ψ$ and Cross Section Measurement of $e^{+}e^{-} \rightarrow π^{\pm}Z_{c}(3900)^{\mp}$ from 4.1271 to 4.3583 GeV

BESIII Collaboration, М. Н. Ачасов, P. Adlarson, O. Afedulidis et autres

Based on 12.0 $\mathrm{fb^{-1}}$ of $e^{+}e^{-}$ collision data samples collected by the BESIII detector at center-of-mass energies from 4.1271 to 4.3583 GeV, a partial wave analysis is performed for the process $e^{+}e^{-} \rightarrow π^{+}π^{-}J/ψ$. The cross sections for the sub processes ${e^{+}e^{-}\rightarrowπ^{+}Z_{c}(3900)^{-}+c.c.\rightarrowπ^{+}π^{-}J/ψ}$, …

Precision measurement of the branching fraction for the decay $ψ(2S)\rightarrowτ^{+}τ^{-}$

BESIII Collaboration, M. Ablikim, М. Н. Ачасов, P. Adlarson et autres

Using $(2259.3 \pm 11.1)\times10^{6}$ $ψ(2S)$ events acquired with the BESIII detector, the branching fraction of $ψ(2S)\rightarrowτ^{+}τ^{-}$ is measured with improved precision to be $\mathcal{B}_{ψ(2S)\rightarrowτ^{+}τ^{-}}=(3.240~\pm~0.023~\pm~0.081)\times 10^{-3}$, where the first and second uncertainties are statistical and systematic, respectively, which is consistent with the world …
