A heterogeneous distribution of nutrients in the soil and root interactions crops coexist agroecosystems. ‘root splitting’ approach, i.e., splitting system into different nutrient compartments, was used to study heterogeneity distributions interactions. We evaluated foraging behavior, individual growth, development mechanisms response nitrogen heterogeneity, intraspecific competition maize. inc...

The physical properties of diamond crystals, such as color or electrical conductivity, can be controlled via impurities. In particular, when doped with nitrogen, optically active nitrogen-vacancy centers (NV), induced. center is an outstanding quantum spin system that enables, under ambient conditions, optical initialization, readout, and coherent microwave control applications in sensing infor...

temperature dependence of the zero-field splitting in the ground state of NV centers in diamond: Nitrogen-vacancy centers in diamond (NV) attract great attention because they serve as a tool in many important applications. The NV center has a polarizable spin S = 1 ground state and its spin state can be addressed by optically detected magnetic resonance (ODMR) techniques. The m S = 0 and m S = ...

consider the linear system ax=b where the coefficient matrix a is an m-matrix. in the present work, it is proved that the rate of convergence of the gauss-seidel method is faster than the mixed-type splitting and aor (sor) iterative methods for solving m-matrix linear systems. furthermore, we improve the rate of convergence of the mixed-type splitting iterative method by applying a precondition...
