The study of ubiquitous learning began in 1991, and has experienced three stages of gestation, start-up and formation and development.After entering the 21 st century, new technologies and new ideas have emerged endlessly. The change in learning methods has led to the flip of classroom teaching, and ubiquitous learning has become more known as the pace of social development. The current higher vocational education presents the characteristics of disjointed education content, misaligned learning roles, and single teaching form. The integration of ubiquitous learning environment into vocational education teaching is a new direction for the development of vocational education.展开更多

In the present study,μ- and m-calpain activity changes were detected in the rat anterior pituitary following intraperitoneal injection of diethylstilbestrol. Double-immunofluorescence labeling confirmed colocalization of μ- and m-calpain in prolactin-secreting cells (lactotrophs). Western blot analysis revealed significantly increased expression of both calpains, which accompanied upregulated cytosol and membrane zymographic activities at 12 weeks following diethylstilbestrol injection, compared with rats injected with sunflower oil. Moreover, following estrogen injection, pituitary gland pathological damage gradually worsened with increasing time. Results demonstrated that estrogen regulated calpain expression and activity, and both calpains participated in the pathophysiological processes of the pituitary gland. Ubiquitous calpain expression could serve as an effective target for anti-estrogen drugs.展开更多

Continuous coverage from close-in "pop-up" targets in clutter to long-range targets impacts selection of waveform parameters. The coherent processing interval (CPI) must be long enough to achieve a certain signal-to-noise ratio (SNR) that ensures the efficiency of detection. The condition of detection in the case of low SNR is analyzed, and three different cases that would occur during integration are discussed and a method to determine the CPI is presented. The simulation results show that targets detection with SNR as low as -26 dB in the experimental system can possibly determine the CPI.展开更多
