We refurbish our axiomatics of differential geometry introduced in [arXiv 1203.3911]. Then the notion of Euclideaness can naturally be formulated. The principal objective in this paper is to present an adaptation of our theory of differential forms developed in [International Journal of Pure and Applied Mathematics, 64 (2010), 85-102] to our present axiomatic framework.

We report the optical perturbation of atomic arrangement in the layered in GeTe/Sb2Te3 phase change memory material. To observe the structural change, the coherent A1 mode of GeTe4 local structure was investigated at various polarization angles of femtosecond pump pulses with the fluence at ≤ 78 μJ/cm2. p-polarization found to be more effective in inducing the A1 frequency shift that can be either reversible or irreversible depending on the pump fluence. The predominant origin of this shift is attributed to rearrangement of Ge atoms driven by anisotropic dissociation of the Ge-Te bonds along the [111] axis after the p-polarized pulse irradiation.

Bioluminescence imaging (BLI) has been applied in gene therapy and research to screen for transgene expression, progression of infection, tumor growth and metastasis, and transplantation. It enables real-time and relatively noninvasive localization and serial quantification of biological processes in experimental animals. In diabetes research, BLI has been employed for the quantification of β-cell mass, monitoring of islet graft survival after transplantation, and detection of reporter gene expression. Here, we explore the use of BLI in a transgenic mouse expressing luciferase under the control of the mouse insulin 1 promoter (MIP-Luc-VU). A previous report on MIP-Luc-VU mice showed luminescence intensities emitted from the islets correlated well with the number of islets in vitro and in vivo. In this study, we showed MIP-Luc-VU mice fed a high fat diet for 8 weeks gave rise to a greater bioluminescent signal than mice fed a regular diet for the same period of time. Conversely, there was a strong reduction in the signal observed in diabetic Mafa-deficient/Mafk-transgenic mutant mice and streptozotocin-treated mice, reflecting the loss of β-cells. Furthermore, we were able to monitor fetal β-cell genesis in MIP-Luc-VU mice during the late gestational stage in a noninvasive and repetitive manner. In summary, we show that bioluminescence imaging of mice expressing a β-cell specific reporter allows detection of changes in β-cell mass and visualization of fetal β-cell neogenesis in uteri.

The Thai government carried out an education opportunity expansion policy to establish the first a half of secondary education course in elementary schools in the '90s. It had an effective result, the quantitative expansion, but it became clear in regard to the equality of the result that there is a limit to learning. Moreover, there is the attendance percentage difference at the now local interval that succeeded in the quantitative expansion. For the cause of this difference, the lowness of the school attendance percentage of the indigenous Thai mountain people is discussed. In later years, the Thai government has began to recognize the indigenous Thai mountain people as Thai citizens and has undertaken policies to build an elementary school in a mountain village to carry out education for the Thai residents there. I am basing this report on a preceding study about the educational issues of the indigenous Thai mountain people and am intended to consider a necessary method to guarantee educational opportunities.
