“…3) Through applying theories in this article, analyzing image of galaxy greatly differing from M51, such as M101 and Hoag's Object shown in Figure 12, as per images in polar coordinate system which these images correspond to, it is verified again that, the shape of rotating arm presents law r θ ∝ , i.e., the rotating arm of spiral galaxy conforms to Archimedes spiral in the shape (it is not given out due to limitation of article length. And independent verification on it is welcomed), but not the present mainstream viewpoint (the shape of rotating arm accords with the logarithmic spiral linetype [15]), which is not an accidental result. Therefore, it further verifies the correctness of this theory.…”

“…Special attention: In the above deduction, the difference between actual rotation trace s of graviton and radius r of its location and xy r is not distinguished especially. In the formula (14), (15) and (16), simply adopt the radius concept of location to replace the concept of actual motion trace. In these two concepts, which one will be adopted to deduce and more accurate in meaning?…”

According to some fundamental hypotheses compatible with microphysics theory in allusion to property of graviton shot by the spiral galaxy, we set up a motion trace equation of graviton in the three-dimensional space, concluding method for measuring the velocity of graviton. This theory reveals formation mechanism of symmetric rotating arm image of the spiral galaxy. The rotating arm image conforms to Archimedes spiral. Under the condition of using dynamic constraints, the image that astrolabe is in thin-disk structure is naturally obtained. And then, we also deduce the law that astrolabe thickness h is inversely proportional to the square root of the distance rxy between astrolabe and galaxy center, according with actual crossrange galaxy observation image excellently. This article, by utilizing several typical galaxy observation images with completely different appearances and shapes, verifies the motion trace law of graviton in three-dimensional space. And the theoretical simulation data meet observation image data very well. As per the discovery in the simulation of three-dimensional theoretical model, changes of parameters in theoretical model will exert a great influence on the shape of galaxy. This theory owns exclusively important meaning, not only to astrophysics, but also to reconstruction and development of relativity theory and the whole basic physics theory, as well as breaking through the current dilemma in studying graviton property.

It is very important to identify the attribute mastery patterns of the examinee in cognitive diagnosis assessment. There are many methods to classify the attribute mastery patterns and many studies have been done to diagnose what the individuals have mastered and or Montel Carl Computer Simulation is used to study the classification of the attribute mastery patterns by Deep Learning. Four results were found. Firstly, Deep Learning can be used to classify the attribute mastery patterns efficiently. Secondly, the complication of the structures will decrease the accuracy of the classification. The order of the influence is linear, convergent, unstructured and divergent. It means that the divergent is the most complicated, and the accuracy of this structure is the lowest among the four structures. Thirdly, with the increasing rates of the slipping and guessing, the accuracy of the classification decreased in verse, which is the same as the existing research results. At last, the results are influenced by the sample size of the training, and the proper sample size is in need of deeper discussion.

“…However they discussed the EC in the case of no superstrong magnetic field (SMF). Luo and Peng [9] analyzed the EC rates at nonzero temperatures. However, in their work, they focused only on the ground state transition and paid no attention to the Gamow-Teller (GT) transition.…”

Based on the theory of relativity in superstrong magnetic fields (SMFs), we have carried out an estimation on electron capture (EC) rates of nuclides 52,53,54,55,56 Fe in the SMFs in magnetars. The rates of change of electronic fraction (RCEF) in the EC process are also discussed. The results show that the EC rates increase greatly and even exceeds by 4 orders of magnitude (e.g. 54 Fe, 55 Fe and 56 Fe) in SMF. On the contrary, the RCEF decreases largely and even exceeds by 5 orders of magnitude in the SMF.
