A circuit model BOSS simulation of nonlinear effects in long distance fiber optic systems
… modulation on the input signal thus modeling the intensity dependent phase shift due to SPM. By changing various parameters of the circuit, the dispersion limited distance, the nonlinearity limited distance and other related factors can be altered. With D=-0.04 ps/km.nm, the effect of changing the …

The impact of harvesting and site preparation on nutrient dynamics, soil erosion and stream water quality in the Virginia Piedmont
… treatment response followed a site preparation intensity dependent gradient. Fifteen, 26, 20 and 45% respectively of the available nitrogen reserves were mineralized within one year following site preparation in the control, chop and burn, shear-disc and shear, pile, disc watersheds. Streamwater …

SYNTHESIS, ELECTRONIC AND OPTO-ELECTRONIC TRANSPORT PROPERTIES OF ATOMICALLY THIN 2D LAYERS OF MoS2, WSe2 and CuIn7Se11
… these materials were explained on the basis of intensity dependent photo-current measurements. From the intensity dependent photo-current along with the low temperature photoconduction measurements we found that in case of liquid phase exfoliated MoS2 thin film devices the trap states are …
