We present a generalized approach for computing electron conductance and I-V characteristics in multiterminal junctions from first-principles. Within the framework of Keldysh theory, electron transmission is evaluated employing an O(N) method for electronic-structure calculations. The nonequilibrium Green function for the nonequilibrium electron density of the multiterminal junction is computed...

The present paper deals with the study of biomass production of manures in the greens such as Amaranthus polygamus and Amaranthus viridis of the family Amaranthaceae and Spinacea oleracea of the family Chenopodiaceae. The medicinal uses and pharmaco - phytochemical analysis were also carried out for the plant species which are widely used as greens.

The fifth-order two-dimensional (2D) Raman signals have been calculated from the equilibrium and nonequilibrium (finite field) molecular dynamics simulations. The equilibrium method evaluates response functions with equilibrium trajectories, while the nonequilibrium method calculates a molecular polarizability from nonequilibrium trajectories for different pulse configurations and sequences. In...

Standard imaging techniques rely on the single scattering assumption. This requires that the recorded data do not include internal multiples, i.e. waves bouncing multiple times between layers before reaching the receivers at the acquisition surface. When multiple reflections are present in the data, standard imaging algorithms incorrectly image them as ghost reflectors. These artifacts can misl...

The paper proposes an efficient phenomenological inversion method to determine the depth profile of a surface-breaking crack in metal from output signal alternating current field measurement (ACFM) probe. proposed utilizes conjugate gradient algorithm minimize objective function, representing difference between probe predicted and actual signals iterative manner. function is derived explicitly ...

results: of the 50 samples tested by the elisa method, 26 samples (52%) were positive for igg . no samples were positive for igm. of the 50 samples tested by the chemiluminescence method, 28 samples (56%) were positive for igg. no samples were positive for igm. conclusions: a significant relationship between the age of the youngest child and the infection rate was seen. no significant correlati...

We develop a theory for the nonequilibrium coherent transport through a mesoscopic region, based on the nonequilibrium Green function technique. The theory requires the weak coupling between the central mesoscopic region and the multiple electrodes connected to it, but allows arbitrary hopping and interaction in the central region. An equation determining the nonequilibrium distribution in the ...
