1. Dendritic attenuation of synaptic current is described by an exponential relationship . 2. Because of this exponential relationship , the BJT has a higher transconductance than the FET. 3. The repulsive interaction should be proportional to the overlap integrals summed of non-bonding orbitals with exponential relationship : 4. This can account for the exponential relationship found by Misson et al . between thinning intensity and mean radial growth. 5. The number of steps required for a solution often has an exponential relationship with the number of loops in the puzzle. 6. The exponential relationship implies that as the cell approaches the limit of efficiency, the increase cost and complexity grow rapidly. 7. A semiconductor diode always has an exponential relationship of current to applied voltage ( neglecting the small reverse leakage current ). 8. However, at a photovoltaic cell's MPP region, its curve has an approximately inverse exponential relationship between current and voltage. 9. The ratio \ frac { p } { p _ 0 } can be calculated over a wide range by assuming an exponential relationship : 10. Kikuchi worked with " Nitella flexillis " cells, and found an exponential relationship between fluid flow velocity and distance from cell membrane.
