The reconstruction of the images of from noisy data. The reconstructions were performed using (a-c) the back-projection formula (BP) in , (d-f) algebraic solution to with 120 iterations and (g-i) the number of iterations that minimized the RMSE, and (j-l) algebraic back-projection (ABP) with 120 iterations in the solution of .

Comparing an algebraic number a and a rational number q. In this case, we know since f(q) and f(r) have different signs

Bar graphs comparing increase in ICP (A) in response to separate ic injection of sodium nitroprusside 0.01 μg/kg and BAY 41-8543 0.3 μg/kg, the algebraic sum of individual responses to sodium nitroprusside and BAY 41-8543 and the response to combination injection of sodium nitroprusside and BAY 41-8543 from the same syringe and bar graphs comparing the area under the curve for the algebraic sum of individual responses to ic injection of sodium nitroprusside and BAY 41-8543 and the response to combination injection with the same syringe.
Bar graphs comparing increase in ICP (B) in response to ic injection of BAY 41-8543 0.1 μg/kg and cavernosal nerve stimulation at 2 Hz, the algebraic sum of responses to ic BAY 41-8543 injection and nerve stimulation at 2 Hz and the combined response to nerve stimulation and ic injection of BAY 41-8543. Bar graphs comparing the area under the curve for the algebraic sum of individual responses to stimulation at 2 Hz and ic injection of BAY 41-8543 and the response to the combined stimuli. n indicates number of experiments, * indicates p < 0.05 when the combined response to BAY 41-8543 and nerve stimulation is compared to the algebraic sum of individual responses to BAY 41-8543 and cavernosal nerve stimulation.

Distribution of algebraic percent errors by target year, 20 year horizon. Note: Number of counties on vertical axis, algebraic percent errors on horizontal axis
