The electronic complexity of the ground-state of the FeMo cofactor of nitrogenase as relevant to quantum simulations. [PDF]

open access: yesJournal of Chemical Physics, 2018
We report that a recent active space model of the nitrogenase FeMo cofactor, proposed in the context of simulations on quantum computers, is not representative of the electronic structure of the FeMo cofactor ground-state.

Egyptian Dialect Stopword List Generation from Social Network Data [PDF]

open access: yesThe Egyptian Journal of Language Engineering, 2015
This paper proposes a methodology for generating a stopword list from online social network (OSN) corpora in Egyptian Dialect (ED). The aim of the paper is to investigate the effect of removing ED stopwords on the Sentiment Analysis (SA) task.

A hybrid modified step Whale Optimization Algorithm with Tabu Search for data clustering

open access: yesJournal of King Saud University: Computer and Information Sciences, 2022
Clustering is a popular data analysis tool that groups similar data objects into disjoint clusters. Clustering algorithms have major drawbacks, such as: sensitivity to initialization and getting trapped in local optima.

Bravyi-Kitaev Superfast simulation of electronic structure on a quantum computer. [PDF]

open access: yesJournal of Chemical Physics, 2017
Present quantum computers often work with distinguishable qubits as their computational units. In order to simulate indistinguishable fermionic particles, it is first required to map the fermionic state to the state of the qubits.
