In a recent study, Manns et al. (2007) showed that CA1 population spiking activity differs in mean phase between conditions of exposure to stimuli of varying levels of familiarity. Here, we provide an analysis of a computational model of the hippocampus from Hasselmo et al. (2002) to examine how an animal's history of exposures to stimuli affects CA1 population activity. We show how the model c...

Abstract: The 3-SAT problem is one of the most important and interesting NP-complete problems with many applications in different areas. In several previous papers we showed the use of ternary vectors and set-theoretic considerations as well as binary codings and bit-parallel vector operations in order to solve this problem. Lists of orthogonal ternary vectors have been the main data structure,...

This paper presents arithmetic operations, including addition and multiplication, in the ternary Galois field through carbon nanotube field-effect transistors (CNTFETs). Ternary logics have received considerable attention among all the multiple-valued logics. Multiple-valued logics are an alternative to common-practice binary logic, which mostly has been expanded from ternary (three-valued) log...

The use of multi-valued logic in VLSI circuits can reduce the chip area significantly. Moreover, there are several additional advantages of using multi-valued logic in VLSI over the conventional Binary logic, such as energy efficiency, cost-effectiveness and so on. It has been shown that Base-3 number system is nearly optimal for computation. This paper is composed of two parts. In the first pa...

We review the main difficulties and advantages in developing CMOS ternary circuits. In addition to employing multiple power sources and multiple thresholds, we describe a new theory of transmission functions for designing CMOS ternary logic circuits. It can explain the main CMOS ternary circuits proposed previously. Computer simulations show that the circuits based on the transmission-function ...
