Optimal Sink Node Placement in Large Scale Wireless Sensor Networks Based on Harris’ Hawk Optimization Algorithm

open access: yesIEEE Access, 2020
Large-scale wireless sensor network (LSWSN) is composed of a huge number of sensor nodes that are distributed in some region of interest (ROI), to sense and measure the environmental conditions like pressure, temperature, pollution levels, humidity, wind,

Simulating the Electronic Structure of Spin Defects on Quantum Computers

open access: yesPRX Quantum, 2022
We present calculations of both the ground- and excited-state energies of spin defects in solids carried out on a quantum computer, using a hybrid classical-quantum protocol.

QUANTUM COMPUTATION WITH BALLISTIC ELECTRONS [PDF]

open access: yesInternational Journal of Modern Physics B, 2001
We describe a solid state implementation of a quantum computer using ballistic single electrons as flying qubits in 1D nanowires. We show how to implement all the steps required for universal quantum computation: preparation of the initial state, measurement of the final state and a universal set of quantum gates.

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.

Reconfigurable computing and electronic nanotechnology [PDF]

open access: yesProceedings IEEE International Conference on Application-Specific Systems, Architectures, and Processors. ASAP 2003, 2004
We examine the opportunities brought about by recent progress in electronic nanotechnology and describe the methods needed to harness them for building a new computer architecture. In this process we decompose some traditional abstractions, such as the transistor, into fine-grain pieces, such as signal restoration and input-output isolation.

C9orf72 ALS‐causing mutations lead to mislocalization and aggregation of nucleoporin Nup107 into stress granules

open access: yesFEBS Letters, EarlyView.
Mutations in the C9orf72 gene represent the most common genetic cause of amyotrophic lateral sclerosis (ALS), a fatal neurodegenerative disease. Using patient‐derived neurons and C. elegans models, we find that the nucleoporin Nup107 is dysregulated in C9orf72‐associated ALS. Conversely, reducing Nup107 levels mitigates disease‐related changes.
