With the rapid development of Internet technology, MOOC has played a certain role in promoting the realization of education equity in China. In order to further improve the quality of teaching, educators are constantly exploring better teaching models. This article aims to optimize the blended learning model by constructing a blended learning model of MOOC+SPOC+flipped classroom in the course of database principles and applications. To enhance the influence of classroom teaching, stimulate and enhance students' interest in learning, and provide reference for the improvement and development of the current blended learning model. At the same time, the specific strategies and practical experience used in the design and practice of MOOC+SPOC+flipped classroom provide valuable references for other teaching practices.

The world is experiencing unprecedented changes, and from historical experience, the era of great changes often means opportunities and challenges. To seize opportunities and better meet challenges, talent is indispensable. Ideological and political education is a very important component of achieving the goal of "cultivating morality and talents" in universities, and it is also a very important way to improve the quality of talent cultivation. Therefore, the article studies the necessity and integration path of ideological and political education in new business majors in the era of great changes, and proposes promotion strategies for the integration of new business majors and ideological and political education, in order to help them better achieve integration in the era of great changes.

Curriculum ideological and political education is an important means to achieve the goal of cultivating morality and nurturing talents. Through the investigation of students' rational identification, emotional cognition, and behavioral tendencies in the early stage of ideological and political education in the course of "Database Principles and Applications", it was found that there are three main problems: weak ideological and political concepts in the course and insufficient value cognition of students; Lack of correlation between curriculum and ideological and political education, and insufficient emotional stimulation of students; The teaching method is single, and the effectiveness of ideological and political education in the curriculum is poor. This article mainly explores the use of OBE education philosophy to enhance teachers' ability to teach ideological and political education through the establishment of curriculum ideological and political concepts; Digging deep into ideological and political elements and reconstructing teaching content; Innovate ideological and political teaching methods and carry out effective teaching; Innovate the evaluation system for ideological and political education in courses, improve the effectiveness of ideological and political education in courses, and achieve educational goals.

The sensitive response of antiferromagnetic order to As ions height in pressure environment makes the reduction of As ions height beneficial for rapid suppression of antiferromagnetism. The analysis from lattice parameters and electron density indicates that As ions height has a significant impact on antiferromagnetic suppression. The interrelationship between As ions height and antiferromagnetic suppression makes it easier for uniaxial pressure along the c‐axis environments to suppress antiferromagnetism, cause Lifshitz transition compared and induce Fermi surface nesting than uniaxial pressure along the a‐axis (or b‐axis) environments, which can explain the fluctuation of superconducting critical pressure measurements in experiments with uneven pressure application from a microscopic perspective.

Cadmium oxide (CdO) has recently attracted attention as a material with controllable properties tailored for optoelectronic and nanophotonic devices due to its superior mobility. However, its potential application in near-infrared (NIR) remains to be explored. In this work, we demonstrate that the epsilon-near-zero (ENZ) wavelength and nonlinear optical properties of CdO films can be effectively tuned by Mo doping. The results show that Mo doping increases the electron concentration as well as improve the crystalline quality of CdO. With increasing Mo doping, we achieve blueshifts of the ENZ wavelength from 2.89 to 1.56 μm. The nonlinear absorption (NLA) behavior at 1550 nm changes from reverse saturable absorption to saturable absorption with increasing Mo content. Moreover, significant improvement in NLA performance with nonlinear absorption coefficient β = −72 cm/GW is observed at the highest doping content. Our work shows that doped CdO films with tunable optoelectrical and nonlinear optical properties can be an ideal candidate for optoelectronic and nanophotonic application in the NIR region.
