Small ubiquitin-related modifier-2/3 (SUMO-2/3) is a member of the ubiquitin-like (Ubl) protein family. Conjugation of SUMO-2/3 to target proteins is influenced by various stress conditions and chemical inhibitors. SUMO-2/3 conjugation may serve as a neuroprotective mechanism and may play a role in protein quality control. A method for screening global changes in SUMO-2/3 conjugation would faci...

Quantum-dot cellular automaton (QCA) is a novel nanotechnology that provides a very different computation platform than traditional CMOS, in which polarization of electrons indicates the digital information. This paper demonstrates designing combinational circuits based on quantum-dot cellular automata (QCA) nanotechnology, which offers a way to implement logic and all interconnections with onl...

Novel digital technologies always lead to high density and very low power consumption. One of these concepts is Quantum-dot Cellular Automata (QCA), which is one of the new emerging nanotechnology-based on Coulomb repulsion. This article presents three architectures of logical “XOR” gate, a novel structure of two inputs “XOR” gate, which is used as a module to implement four inputs “XOR” gate a...

Reversible logic enables ultra-low power circuit design and quantum computation. Quantum-dot Cellular Automata (QCA) is the most promising technology considered to implement reversible circuits, mainly due correspondence between features of QCA circuits. This work aims push forward state-of-the-art QCA-based circuits implementation by proposing a novel full adder\full subtractor (FA\FS). At fir...

The large amount of secondary effects in complementary metal–oxide–semiconductor technology limits its application the ultra-nanoscale region. Circuit designers explore a new for region, which is quantum-dot cellular automata (QCA). Low-energy dissipation, high speed, and area efficiency are key features QCA technology. This research proposes novel, low-complexity, QCA-based one-bit digital com...
