Robust QCA Full Adders Using a Novel Fault Tolerant Five-Input Majority Gate [PDF]

open access: yesInternational Journal of Industrial Electronics, Control and Optimization
A novel technique for creating logic gates and digital circuitry at the nanoscale is quantum cellular automata (QCA). The sensitivity of the circuit is enhanced and quantum circuits are more susceptible to unfavorable external conditions when component ...

Public opposition to protest online: A qualitative content analysis of YouTube comments on UK climate activism videos

open access: yesAnalyses of Social Issues and Public Policy, Volume 26, Issue 3, December 2026.
Abstract Public discourse plays a crucial role in shaping the success of social movements. While research has explored public support for collective action, less attention has been paid to active opposition and delegitimization strategies. This study investigates the discursive contestation of climate protests by Extinction Rebellion and Just Stop Oil ...

Design of reversible logic circuits using quantum dot cellular automata-based system

open access: yesNanotechnology Reviews, 2015
Shrinking transistor sizes and power dissipation are the major barriers in the development of future computational circuits. At least when the transistor size approaches the atomic scale, duplication of transistor density according to Moore’s law will ...

Microfoundations of Adaptive Decision‐Making Capability: How Chief Supply Chain Officers Convert Technology‐Enabled Visibility Into Coordinated Action

open access: yesJournal of Business Logistics, Volume 47, Issue 4, October 2026.
ABSTRACT Supply chain leaders increasingly operate with extensive technology‐enabled visibility, yet many firms still struggle to convert shared signals into timely, coordinated action. We frame this tension as the visibility‐to‐action problem in supply chain management (SCM): executives observe more than they can process and often fail to route ...

Cost-Effective Synthesis of Qca Logic Circuit Using Genetic Algorithm

open access: yes, 2023
Quantum-dot cellular automata (QCA) is a field coupling nano-technology that has drawn significant attention for its low power consumption, low area overhead, and achieving a high speed over the CMOS technology. Majority Voter (MV) and QCA Inverter (INV)

Enabling effective urban green space stewardship through planning: A qualitative comparative analysis in Southwest England

open access: yesPeople and Nature, Volume 8, Issue 8, Page 2559-2575, August 2026.
Abstract Amid increasing urbanisation and biodiversity decline, ‘effective stewardship’ of urban green space (UGS) is a complex but critical nature‐based solution for long‐term environmental, social and economic gain. Combining stewardship and sense‐of‐place frameworks with European nature‐based solutions guidance, we investigate which social and ...

Fault Tolerant QCA Logic Design With Coupled Majority-Minority Gate

open access: yesInternational Journal of Computer Applications, 2010
Synthesis of efficient DFT (Design for Testability) logic is of prime importance in robustly testable design of QCA based logic circuits. An ingenious universal QCA gate structure, Coupled Majority-Minority (CMVMIN) gate, realizes majority and minority functions simultaneously in its 2-outputs.

A Novel Area Efficient and High‐Speed BCD Adder Using CFA and Multiplexer in Quantum‐Dot Cellular Automata

open access: yesIEEJ Transactions on Electrical and Electronic Engineering, Volume 21, Issue 2, Page 226-234, February 2026.
This paper proposes a new enhanced Single Digit BCD Adder (SDBA) to perform decimal addition optimally. Quantum‐dot Cellular Automata (QCA) will construct nanostructured arithmetic circuits for future computing. One of the vital structures in arithmetic structures is the Binary Coded Decimal (BCD)/Decimal Adder. The existing Decimal Adders require many
