Methodology for three-dimensional analysis of asymmetries in joint moments in cycling [PDF]
Frontiers in Bioengineering and BiotechnologyBackground and introductionThe assessment of lower-limb joint moment asymmetries during cycling is critical, as inter-limb imbalances may lead to performance decrements, overload, or injury risk.

Multiple magnitudes and their cleverness
地震科学进展, 2022 Magnitude is a measure of the size of an earthquake. In practical work such as seismic activity analysis, people usually think that an earthquake has only one magnitude. Many people will have such doubts：why use multiple magnitudes?

Terrestrial, Atmospheric and Oceanic Sciences, 2022 Key points logEs is proportional to 2.0ML for the Shoufeng earthquake sequence in Taiwan. A crossover magnitude detected at ML = 4.0 divides the MW–ML relation into two parts. For ML > 4.0, logM0 ∝ 0.67ML and MW ∝ ML; for ML

Dizhen xuebao, 2021 根据地震波衰减特性，采用一维速度模型开展了快速测定辐射能量ES和能量震级Me的方法研究。利用全球地震台网和国家数字测震台网提供的宽频带资料，测定了2014—2019年间MW≥6.0的115次浅源地震的辐射能量和能量震级，将计算结果与其它机构的结果进行对比。结果表明：利用本文方法可在得到地震数据半小时内计算出稳定的Me，且本文的测定结果与美国地震学研究联合会的结果基本一致。地震造成的灾害与能量震级的大小密切相关，当Me＞MW时，地震灾害较为严重；在所有的地震类型中，发震断层类型为走滑型时 ...

Dizhen xuebao, 2023 利用国家地震台网和全球地震台网的宽频带远震P波波形数据，通过测定2014—2019年间国内MW≥6.0和国外MW≥6.5共105次浅源地震的辐射能量和能量震级，研究了震源机制解对辐射能量估计的影响。结果表明：① 震源机制不同导致地震能量辐射差异较大，其中走滑型地震对辐射能量的影响最大，对能量震级的平均影响因子为0.34，正断型地震对能量震级的平均影响因子为0.08，逆断型地震对能量震级的影响最小，平均影响因子为0.05；② 不同震源机制类型地震的差震级ΔM也不同，走滑型地震的ΔM为 0.31 ...
