Supplement Number 1: Fitted Polynomial Coefficients for Expansion and Collapse Phases using DWO method

Polynomial coefficients ($a_{0}$--$a_{5}$) with standard deviations ($\sigma$), together with the initial conditions ($R_{0}$, $\dot{R}_0$), collapse radius ($R_{c}$), and RMSE values, reported separately for expansion and collapse phases across hypobaric conditions ($p_{\infty}$) and collapse cycles.

该数据集收录了多项式系数（a₀~a₅）及其标准差（σ），同时涵盖初始条件（R₀、Ṙ₀）、坍缩半径（R_c）与均方根误差（Root Mean Square Error，RMSE）；所有参数将依据低压环境（p_∞）与坍缩循环，分别针对膨胀阶段与坍缩阶段单独报告。
