Singular value decomposition with normalized period for magnetocaridiography signal processing

In this paper, we have developed an algorithm based on singular value decomposition (SVD) for matrix. And the novel SVD algorithm with normalized period of cardiac cycles is presented. The results from real magnetocardiography (MCG) data processing show that the new algorithm is better than the standard one not only in suppressing noises, but also in providing high-fidelity MCG signals.

Theoretical and Experimental Study of Scattering of a Plane Wave by an Inhomogeneous Plasma Sphere

Scattering of electromagnetic waves by an inhomogeneous plasma sphere has been studied theoretically and experimentally. The offset angles of electromagnetic waves caused by the plasma sphere have been observed experimentally. The effects of the electromagnetic wave frequency and plasma density on the offset angle are discussed. The plasma density is estimated with the offset angle.

Formation of Nanographite Using GaPO4-LTA as Template

An attempt was made to prepare nanographite with uniform size by pyrolysis of 4-methyl pyridine (MPy), which is the structure-directing agent for the formation of GaPO4-LTA single crystals, in the GaPO4-LTA framework at 760 ℃. The as-prepared nanographite has been examined by Raman spectroscopy, transmission electron microscopy (TEM), electron spin resonance (ESR) and magnetization characterizations. The TEM image shows that the size of individual nanographite particles is about 7 nm, and it is proved that there are spins of sp^2-type (π-type) radical electrons localized on the zigzag edge sites of the nanographite. The magnetic susceptibility of the nanographite shows crossover from a high-temperature diamagnetic to a low-temperature paramagnetic behavior, in good agreement with the theoretical expectation.

“不当出生”诉讼初探——透过生命价值的迷雾看赔偿正义

"不当出生"是因医生的产前诊断过失或者通知过失导致先天残障孩子出生引发的诉讼。"不当出生"诉讼在发展中逐渐获得了一定的认可,但是关于"不当出生"损害赔偿正当性的争论始终存在着。"不当出生"问题的复杂性在于其涉及生命价值与赔偿正义的冲突与协调。肯定特别损害赔偿而否定一般损害赔偿是平衡上述两项价值的较好选择。
