Polaron properties are studied in bulk wurtzite nitride ternary mixed crystals AxB1-xN (A, B = Al, Ga, In) with the use of a dielectric continuum Fröhlich-like electron-phonon interaction Hamiltonian. The polaronic self-trapping energy and effective mass are analytically derived by taking...

The eigenproblems of spin waves in a heterogeneous ferromagnetic bilayer system with periodic boundary conditions are solved using the interface-rescaling approach. Brillouin zone mapping and the eigenmodes of the system are investigated. We find three types of spin waves may exist in the...

This paper uses farm panel data from China to examine the dynamics of land transactions, machine investments, and the demand for machine services. Recently, China's agriculture has experienced a large expansion of machine rentals and machine services provided by specialized agents, which has...

The rapid development of the electricity industry reform in China has been witnessed in recent years, and one of the iconic achievements could be the establishment and trial operation of the electricity spot markets. However, even though the market clearing model for electric energy is identical...

Purpose: This study examines how community norms, such as religious atmosphere and economic pressures, affect corporate philanthropic giving. Grounded in upper echelon theory, the authors further focus on how the women on board of directors (BODs) play an important role in the relationship...
