We establish a lower bound for deciding the satisfiability of the conjunction of any two Boolean formulas from a set called a full representation of Boolean functions of n variables a set containing a Boolean formula to represent each Boolean function of n variables. The contradiction proof first assumes that there exists a Turing machine with k symbols in its tape alphabet that correctly decid...

We establish a lower bound of 2 conditional branches for deciding the satisfiability of the conjunction of any two Boolean formulas from a set called a full representation of Boolean functions of n variables a set containing a Boolean formula to represent each Boolean function of n variables. The contradiction proof first assumes that there exists a Post machine (Post’s Formulation 1) that corr...

background: vitamin b12 (cobalamin) deficiency can result in some clinical and paraclinical characteristics similar to what is seen in multiple sclerosis (ms) patients. this study aimed to evaluate the controversial association between vitamin b12 deficiency and ms. methods: we measured serum vitamin b12 in 60 patients with ms and 38 healthy controls. clinical disability was evaluated according...
