Qualitative Comparative Analysis: Search Target, Reflection on the Top-Down Approach, and Introduction of the Bottom-Up Approach

open access: yesInternational Journal of Qualitative Methods, 2023
Based on the INUS theory of causality, the search target of qualitative comparative analysis (QCA) is to find all the minimally sufficient conditions for the outcome’s occurrence in a data set, where the condition’s sufficiency , the necessity of the ...

Coplanar QCA crossovers

open access: yesElectronics Letters, 2009
Quantum-dot cellular automata (QCA) is one of the promising next-generation fabrics for circuits. Coplanar wire crossings are one of the more elegant features of this new low-power computing paradigm. Proposed are coplanar wire crossovers using a single type of QCA cells, which has significant implications in fabrication and fault tolerance.

Charting the Course: Real‐World Application of Sustainability and Innovation Principles in the Portuguese Blue Economy Firms

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The blue economy has emerged as a key sector for linking sustainability and innovation, yet existing research has largely overlooked how firms operationalize these processes in practice. This study addresses that gap by asking: How do Portuguese blue economy firms embed sustainability‐oriented innovation (SOI) into their strategies, and what ...

Consumers' Intention to Use Circular Business Models: A Configurational Analysis

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Circular business models (CBMs) integrate ecological sustainability and resource efficiency into core business strategies, but their success depends on consumers' intention to use. Grounded in expectancy–value theory, this study investigates how product‐related factors (perceived usefulness, convenience, value for money, and performance risk ...

Stent boost enhancement compared to intravascular ultrasound in the evaluation of stent expansion in elective percutaneous coronary interventions

open access: yesThe Egyptian Heart Journal, 2018
Background: Stent underexpansion is a major risk factor for in-stent restenosis and acute in-stent thrombosis1Intravascular ultrasound (IVUS) is one of the standards for detection of stent underexpansion (de Feyter et al.

Synchronization in Quantum-Dot Cellular Automata Circuits and Systems

open access: yesIEEE Open Journal of Nanotechnology, 2020
Signal synchronization of large scale Quantum-dot Cellular Automata (QCA) circuits is one of the most complex QCA design challenges. More specifically, the QCA circuits synchronization problem, especially in the large circuits, is characterized as rather

A Comparison of Regional Decisions for Doses and Administrations of New Drugs: Concordance, Discordance, and Dependencies

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Regional differences in approved drug dosages and administration are shaped by complex factors, including clinical data, prior regulatory decisions, and region‐specific considerations. This study investigated how such factors are associated with variations in approved doses across the United States Food and Drug Administration (FDA), European Medicines

Validation of artificial intelligence-based quantitative coronary angiography

open access: yesDigital Health
Background Coronary angiography is fundamental for the diagnosis and treatment of coronary artery disease. Manual quantitative coronary angiography (QCA) is accurate and reproducible; however, it is time-consuming and labor-intensive.
