Modern nuclear force predictions for the neutron-deuteron scattering lengths [PDF]

, 2003
The nd doublet and quartet scattering lengths have been calculated based on the modern NN and 3N interactions. We also studied the effect of the electromagnetic interactions in the form introduced in AV18. Switching them off for the various nuclear force

Nuclear Force and Nuclear Matter. II [PDF]

Progress of Theoretical Physics, 1966
The saturation curves of the nuclear matter are calculated by using the reference specturm method (RSM) for five types of nuclear forces: the Gammel-Thaler potential, the Ramada­ Johnston potential, two kinds of potentials derived by Tamagaki and Watari which have very small core radii, and a potential having a negative l-s force.

Nuclear force in Lattice QCD

, 2006
We perform the quenched lattice QCD analysis on the nuclear force (baryon-baryon interactions). We employ $20^3\times 24$ lattice at $\beta=5.7$ ($a\simeq 0.19$ fm) with the standard gauge action and the Wilson quark action with the hopping parameters ...

Electrical admittance-based evaluation of piezoelectric active sensor condition using k-nearest neighbors and least-squares regression

AIP Advances, 2021
In the electromechanical impedance-based health monitoring of structures, partial failure of piezoelectric lead zirconate titanate will result in signal changes, which may cause misjudgment of the structure state.

基于GA-XGBoost的天然地震与爆破的小样本分类

Dizhen xuebao
由于爆破数据数量有限，利用分类法识别天然地震与爆破会遇到诸多困难。鉴于此，本文建立了高维特征小样本数据集，基于XGBoost模型利用遗传算法（GA）实现对主要影响XGBoost模型分类准确率的迭代次数、最大树深和学习率等三个重要超参数的自主寻优，构建出了GA-XGBoost模型，并将该模型应用于功率谱特征样本集，结果显示：爆破与天然地震的分类准确率高达94.094%；相比于传统的GS-XGBoost模型（准确率91.787%），GA-XGBoost模型在显著提升分类准确率的同时，其运行时间也由409 ...

Mechanically Activated Calcium Channel PIEZO1 Modulates Radiation-Induced Epithelial-Mesenchymal Transition by Forming a Positive Feedback With TGF-β1

Frontiers in Molecular Biosciences, 2021
TGF-β-centered epithelial-mesenchymal transition (EMT) is a key process involved in radiation-induced pulmonary injury (RIPI) and pulmonary fibrosis. PIEZO1, a mechanosensitive calcium channel, is expressed in myeloid cell and has been found to play an ...
