The widely used energy transfer theory is a foundation of luminescence, in which the rates of Stokes and anti-Stokes processes have the same calculation formula. An improvement on the anti-Stokes energy transfer to explain the fluorescence intensity reversal between the red and green fluorescence of Er（0.5）Yb（9.5）：FOV is reported in the present article. The range of the intensity reversal Z was measured to be 877. Dynamic processes for 16 levels were simulated. A coefficient, the improvement factor of the intensity ratio of Stokes to anti-Stokes processes in quantum Raman theory compared to classical Raman theory, is introduced to successfully describe the anti-Stokes energy transfer. A new method to calculate the distance between the rare earth ions, which is critical for the energy transfer calculation, is proposed. The validity of these important improvements is also proved by experiment.

对稀土离子能级的动力学过程进行了数值计算,并对各个能级的布居概率改变进行了分析。发现如果不考虑斯托克斯过程和反斯托克斯过程之间的区别而采用原有声子辅助能量传递理论中相同的计算公式对待两种过程的话,得到的理论计算结果就与我们实验得到的校准的结果不一致,为了能够准确描述反斯托克斯能量传递过程,众所周知的量子喇曼理论相对于经典拉曼理论在斯托克斯与反斯托克斯过程的强度比上所增加的比值系数exp{ΔE/kT}被首次成功地引入来描述反斯托克斯能量传递。在能量传递计算理论中引入该比值系数之后,理论计算结果与实验结果符合的非常好,并且发现该比值系数在对纳米尺度材料的光子学研究探索中会发挥至关重要的作用。

Introduction We have been exploring on Pressure Sensitive Adhesives(PSAs) from the standpoint of viscoelastic properties and phase structures and morphology of polymers,where it was found that PSAs performances, such as peel strengths,tack,and shear creep resistance are greatly dependent on the viscoelastic properties of bulk properties of PSAs. For example,in the case that base polymers and tackifiers are miscible,in other word the shifts of

Nanotechnology is developing rapidly and the production of novel man-made nanoparticles is increasing. However, the effects of these particles on human health are unevaluated. Depending on particle size and the surface properties, nanoparticles may have the potential to affect human health. In recent studies, several silica nanoparticles (<100 nm) were shown to be penetrating into the brain. Thus, it is important to understand the influence of these nanoparticles on the central nervous system. In this study, we investigated the toxicological influence of nanoparticles on cortical cultured neurons isolated from embryonic day 18 Wister rats. Cortical cultured neurons at 21 days in vitro (DIV) were treated with 30 nm silica nanoparticles for 1 hr. Many neurons were damaged immediately more than at 0.01 mg/ml concentration of silica. Cell damage was also assessed using the lactate dehydrogenase (LDH) assay and the reactive oxygen species (ROS) assay. We revealed that the Neuro-toxicological mechanisms were due to membrane permeability. It was suggested that cell membrane permeability was enhanced because of ROS generation. Given these results, it will be important to determine the effect of nano-silica particles in vivo and identify the extent of neuronal damage.

Background: Health consciousness in daily life is very important because lifestyle habits, such as dietary and exercise habits, sleep, and smoking, are involved in the development and progression of lifestyle-related diseases, such as cancer, heart diseases, stroke, liver diseases, kidney diseases, and diabetes. Purpose: In this study, we surveyed to see if the health consciousness increased and what behaviors in daily life changed in students of a nursing school (Seiwa Nursing College, Tokyo, Japan) after they learned medical care knowledge required to become a nurse. Results: After learning medical care knowledge for 3 years, the students were found to have a higher level of health consciousness in the third year than they did in the first year. They applied the medical care knowledge they learned in daily life. All data were collected in 2019. Conclusions: The medical care knowledge learned in a nursing school was demonstrated to serve as information to increase the health consciousness.
