In this paper, the free vibration behaviors and flexural sensitivity of atomic force microscope cantilevers with small-scale effects are investigated. To study the small-scale effects on natural frequencies and flexural sensitivity, the consistent couple stress theory is applied. In this theory, the couple stress is assumed skew-symmetric. Unlike the classical beam theory, the new model contain...

research on ambidexterity is burgeoning, yet understanding of the antecedents and consequences of both activities remains rather unclear. the purpose of this paper is to explore the effects of knowledge sharing on organizational ambidexterity (exploration and exploitation) as well as the mediating effect of mediating role of absorptive capacity. the research statistical population constitutes 9...
