Neuronal Networks: Flip-Flops in theBrain
Neuronal activity can rapidly flip-flop between stable states. Although these semi-stable states can be generated through interactions of neuronal networks, it is now known that they can also occur in vivo through intrinsic ionic currents.
متن کاملSEU-Resistant Magnetic Flip Flops
The development of a practical magnetic tunneling junction (MTJ) ten years ago allowed the creation of a new class of non-volatile memories. This technology may offer superior resistance to total ionizing dose and virtually unlimited write endurance, making it more attractive than flash memories for space applications. Although a number of manufacturers are developing high-density bulk magnetic...
متن کاملAging Effects Analysis in Flip-Flops
This work presents a methodology to analyze aging effects in different flip-flops topologies. As CMOS transistor scaling to nanometer technologies in the last decades, new issues have become major concerns in VLSI design. One of those new issues is aging. Aging effects impact on performance and reliability of CMOS circuits. Flip-flops are one of the main structures in VLSI circuits. Their chara...
متن کاملQuantum-dot Cellular Automata of Flip-flops
The use of quantum-dots is a promising emerging technology for implementing digital systems at the nano-scale level. Recently studied computational paradigms for quantum-dot technology include the use of locally connected quantum-dot cellular automata (QCA). This technique is based on the interaction of electrons within quantum dots that take advantage of quantum phenomena; the same phenomena t...
متن کاملMolecular mechanism for lipid flip-flops.
Transmembrane lipid translocation (flip-flop) processes are involved in a variety of properties and functions of cell membranes, such as membrane asymmetry and programmed cell death. Yet, flip-flops are one of the least understood dynamical processes in membranes. In this work, we elucidate the molecular mechanism of pore-mediated transmembrane lipid translocation (flip-flop) acquired from exte...
