Boundedness for sublinear reversible systems with a nonlinear damping and periodic forcing term

AbstractIn this paper, we are concerned with the sublinear reversible systems with a nonlinear damping and periodic forcing termx″+f(x)g(x′)+γ|x|α−1x=p(t), where f(x), p(t) are odd functions, p(t) is smooth 1-periodic function and γ≠0 is a constant. A sufficient and necessary condition for the boundedness of all solutions of the above equation is established. Moreover, we show the existence of Aubry–Mather sets as well

Towards a Theoretical Framework of E-Business Value Creation: the Dynamic Capabilities Perspective

With increasing attention on e-business and its implications for firm performance from both academia and practitioners, the study focuses on the mechanism under which e-business contributes to firm competitive advantage in the uncertain and dynamic environment. Drawing upon resource-based theory and dynamic capabilities approach, this study develops a theoretical framework that links e-business engagement to firm capabilities, and then firm performance. By emphasizing the implications of e-business in capabilities-building, the framework not only advances our understanding of the roles of e-business in firm, but also provides a sound theoretical basis for further empirical studies on this topic. The implications of this research for practitioners are discussed

5-(Pyridin-2-yl)-3,3′-bi(1H-1,2,4-triazole)

In the title mol­ecule, C9H7N7, the two triazole rings are twisted by an angle of 3.8 (5)°; the central triazole ring is twisted by 32.3 (6)° with respect to the pyridyl ring. The crystal packing consists of layers generated by inter­molecular N—H⋯N hydrogen bonds
