We consider the canonical quantization of a generalized two-dimensional massive fermion theory containing higher odd-order derivatives. The requirements of Lorentz invariance, hermiticity of the Hamiltonian and absence of tachyon excitations suffice to fix the mass term, which contains a derivative coupling. We show that the basic quantum excitations of a higher-derivative theory of order 2N + ...

objective(s):  the field of nanotechnology is rapidly expanding .the development quantum dots quantum dot (qds), show great promise for treatment and diagnosis of cancer and targeted drug delivery little data on the toxicity of qds, especially for in vivo applications, are available. as a result, concerns exist over their toxicity for in vivo applications. then, cytotoxic effects of cadmium sel...

We explore determinants of subsidiary autonomy in setting HRM practices within US parented MNEs, in Europe and Australia. We examine both the effect of strategic context, and the effect of the institutional location of the subsidiary. We find that US MNEs show greater centralization of control over HRM where the subsidiary faces global markets, in coordinated market economies versus liberal mar...

In this paper, the author investigates intrapreneurship in software subsidiaries of multinational corporations in India using an analogous concept—subsidiary initiative— that has been used in the international business literature. Subsidiary initiative is a discrete, proactive undertaking by an operational unit situated outside the home country that advances a new way for the corporation to use...

Abstract Randomness lays the foundation for information security. Quantum random number generation based on various quantum principles has been proposed to provide true randomness in last two decades. We integrate four different types of generators Alibaba Cloud servers enhance cybersecurity. Post-processing modules are integrated into platform extract numbers. employ improved authentication pr...
