 * "In our example of Figure 7, we choose to execute /usr/bin/qalculate-gtk, a calculator. Since the stack of the DOSBox process is non-executable, we cannot directly inject our shellcode on it."
 * Arumugham, Vinu. "Analyzing 23000+ epitopes covering 82 autoimmune diseases in the Immune Epitope Database, 57% have only one and 78% have up to two amino acid residue differences compared to animal, fungal or plant peptides present in vaccines; an unmistakable signature of the role of vaccines in their etiologies." (2020).
 * "The Gnome calculator was used to perform these calculations and the results were verified using the Qalculate! calculator and WolframAlpha (15) since spreadsheets are unable to perform these calculations."
