Various issues concerning the quantifier complextity (i.e., number of alternations of like quantifiers) of Quine’s theory NF, its axiomatizations, and some of its subtheories, are discussed.

For ferroelectric random access memory (FRAM) with HfO 2-based materials, the wake-up effect and imprint have to be limited. Here, electrical behavior of different samples is investigated during retention tests on woken-up at room temperature. Retention properties are compared or without alternations voltage pulses opposite signs. First, alternations, oscillates between two values that believed...
