Increasing the Reproducibility and Replicability of Supervised AI/ML in the Earth Systems Science by Leveraging Social Science Methods

Earth and Space Science, Volume 11, Issue 7, July 2024.
Abstract Artificial intelligence (AI) and machine learning (ML) pose a challenge for achieving science that is both reproducible and replicable. The challenge is compounded in supervised models that depend on manually labeled training data, as they introduce additional decision‐making and processes that require thorough documentation and reporting.

Operation of Quantum Cellular Automaton cells with more than two electrons

, 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).

The effects of agricultural output market access interventions on agricultural, socio‐economic, food security, and nutrition outcomes in low‐ and middle‐income countries: A systematic review

Campbell Systematic Reviews, Volume 20, Issue 2, June 2024.
Abstract Background An estimated two billion people do not have sufficient access to nutritious food, and nearly half are dependent on small‐scale and subsistence farming. Projections show that the global population is not on track to reach the Sustainable Development Goals.

Quasi-adiabatic Switching for Metal-Island Quantum-dot Cellular Automata

, 2000
Recent experiments have demonstrated a working cell suitable for implementing the Quantum-dot Cellular Automata (QCA) paradigm. These experiments have been performed using metal island clusters. The most promising approach to QCA operation involves quasi-

Simulation of a non-invasive charge detector for quantum cellular automata

, 1998
Information in a Quantum Cellular Automata architecture is encoded in the polarizazion state of a cell, i.e., in the occupation numbers of the quantum dots of which the cell is made up.

A Quantum Game of Life [PDF]

, 2010
This research describes a three dimensional quantum cellular automaton (QCA) which can simulate all other 3D QCA. This intrinsically universal QCA belongs to the simplest subclass of QCA: Partitioned QCA (PQCA).
