Dizhen xuebao, 2018 为更高效合理地生成与设计反应谱相符的人造地震动信号，本文基于自主开发的地震动信号处理软件EQSignal对人造地震动生成过程中涉及的几个问题进行了探讨，并通过对单自由度简谐共振体系的响应分析，提出了具体的解决建议：① 反应谱求解时应该对高频段和低频段分别采用频域传递函数法和逐步积分法求解；② 反应谱周期控制点的分布模式也应分段处理，短周期段宜采用对数平均分布，长周期段宜采用线性平均分布，反应谱总周期控制点不宜少于120个；③ 人造地震动反应谱与设计反应谱拟合的过程中 ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background B‐acute lymphoblastic leukemia (B‐ALL) is the most common pediatric cancer, and while most children in high‐resource settings are cured, therapy carries risks for long‐term toxicities. Understanding parents’ concerns about these late effects is essential to guide anticipatory support and inform evolving therapeutic approaches ...

A stochastic approach for deriving effective linear properties of bilinear hysteretic systems subject to design spectrum compatible strong ground motions [PDF]
, 2011 A novel statistical linearization based approach is proposed to derive effective linear properties (ELPs), namely damping ratio and natural frequency, for bilinear hysteretic oscillators subject to seismic excitations specified by an elastic response ...

Local Primordial Non-Gaussianities and Super-Sample Variance
, 2020 Fluctuations with wavelengths larger than the volume of a galaxy survey affect the measurement of the galaxy power spectrum within the survey itself. In the presence of local Primordial Non- Gaussianities (PNG), in addition to the super-sample matter ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM
FEBS Letters, EarlyView.Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Investigation of peak shapes in the MIBETA experiment calibrations
, 2012 In calorimetric neutrino mass experiments, where the shape of a beta decay spectrum has to be precisely measured, the understanding of the detector response function is a fundamental issue. In the MIBETA neutrino mass experiment, the X-ray lines measured

Solar neutrino event spectra: Tuning SNO to equalize Super-Kamiokande [PDF]
, 2001 The Super-Kamiokande (SK) and the Sudbury Neutrino Observatory (SNO) experiments are monitoring the flux of B solar neutrinos through the electron energy spectrum from the reactions nu_{e,mu,tau} + e --> nu_{e,mu,tau} + e and nu_e + d --> p + p + e ...
