Operation of Quantum Cellular Automaton cells with more than two electrons

open access: yes, 1999
We present evidence that operation of QCA (Quantum Cellular Automaton) cells with four dots is possible with an occupancy of 4N+2 electrons per cell (N being an integer).

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

open access: yesPeople and Nature, EarlyView.
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 ...

Successful water governance pathways across problem contexts: a global qualitative comparative analysis

open access: yesEcology and Society
It is widely acknowledged that the global water crisis is a governance crisis. To be effective, governance interventions must be designed to align with the specific context in which they are implemented.

Design of a Galois Field Multiplier Circuit using Quantum-dot Cellular Automata

open access: yesНаука. Инновации. Технологии, 2022
The Quantum-dot Cellular Automata (QCA) is a possible future of nano-electronics computing technology, that promises small size, low power, and fast digital circuits compared to the existing transistor-based designs.

Pseudo-random operators of the circular ensembles

open access: yes, 2004
We demonstrate quantum algorithms to implement pseudo-random operators that closely reproduce statistical properties of random matrices from the three universal classes: unitary, symmetric, and symplectic.

Thermodynamics and dynamics of two-dimensional systems with dipole-like repulsive interactions [PDF]

open access: yes, 2018
Thermodynamics and dynamics of a classical two-dimensional system with dipole-like isotropic repulsive interactions are studied systematically using extensive molecular dynamics (MD) simulations supplemented by appropriate theoretical approximations ...

Navigating Drivers and Barriers to the Implementation of Education for Sustainable Development at Two Swedish Business and Management Schools

open access: yesSustainable Development, EarlyView.
ABSTRACT Despite the significance of Education for Sustainable Development (ESD), ESD implementation faces challenges, especially economic obstacles in a global world. This study explores the drivers and barriers to ESD implementation at two Swedish business and management schools (BMSs).

Carbon Performance in Airlines: A Qualitative Comparative Analysis of Institutional and Firm‐Level Drivers

open access: yesSustainable Development, EarlyView.
ABSTRACT Air transport is one of the fastest‐growing sources of greenhouse gas emissions, yet it remains one of the most difficult sectors to decarbonize. The sector's climate impact is amplified by two factors: the steady rise in passenger demand and the absence of commercially viable low‐carbon technologies for long‐haul flights.

Reproducible QCA studies with fs/QCA

open access: yes, 2015
The ability to reproduce published empirical studies is central to progress in science. Reproducibility requires the proper storage and sharing of data, which cannot be taken for granted, and a detailed, step-by-step description of the empirical analysis.

What entrepreneurial decisions enable the breeding of digital platform unicorns?

open access: yesStrategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary Digital platforms have revolutionized business sectors; however, despite their significant success, platform unicorns remain rare. While extensive research exists on digital platform growth, it is uncertain what entrepreneurial decisions achieve unicorn status.
