Performance Analysis of Modulating Retroreflector Array for UAV-Based FSO Links
(
IEEE
, 2023 , Article)
In this work, we investigate the performance of free space optical (FSO) communication systems based on modulating retroreflector (MRR) array. In particular, we first characterize the MRR array-based FSO channel by taking ...
Channel Modeling and Performance Analysis of Directional THz Links Under Pointing Errors and α-μ Distribution
(
IEEE
, 2023 , Article)
This letter focuses on providing an analytical framework for the quantification and evaluation of high-directional terahertz communication links under pointing errors in terms of outage probability (OP), channel capacity, ...
Perspectives of healthcare workers on integrated management of childhood illness in Pakistan: A phenomenological approach
(
SAGE
, 2024 , Article)
In 2019, an estimated 5.2 million deaths were reported among children less than 5 years of age. At primary healthcare level, healthcare workers (HCWs) mostly rely on history and clinical findings and less on inadequate ...
Comprehensive molecular and clinical insights into non-small cell lung cancer transformation to small cell lung cancer with an illustrative case report
(
Taylor & Francis
, 2024 , Article)
Histologic transformation to small cell lung cancer (tSCLC) is a rare but increasingly recognised mechanism of acquired resistance to tyrosine kinase inhibitors (TKI) in patients with epidermal growth factor receptor ...
Long-Haul mmWave Sky Links: A Multi-Hop NFP-Based Design and Analysis
(
IEEE
, 2023 , Article)
Networked flying platforms (NFPs) have emerged as a favorable solution to extend the network coverage and/or capacity in temporary scenarios, such as disasters or mega-size events, thanks to their flexibility and cost ...
Toxicity assessment of di(2-ethylhexyl) phthalate using zebrafish embryos: Cardiotoxic potential
(
Elsevier
, 2024 , Article)
Plasticizers are considered as newly emerged contaminants. They are added to plastics to increase their flexibility and softness. Phthalate plasticizers including the Di-2-ethylhexyl phthalates (DEHP) are toxic and induce ...
A General Model for Pointing Error of High Frequency Directional Antennas
(
IEEE
, 2022 , Article)
This paper focuses on providing an analytical framework for the quantification and evaluation of the pointing error for a general case at high-frequency millimeter wave (mmWave) and terahertz (THz) communication links. For ...
Performance Analysis of Two-Way Relaying in mmWave-Based Aerial Links
(
IEEE
, 2024 , Article)
Two-Way Relaying (TWR) is an efficient relaying technique that doubles the spectral efficiency as compared to the traditional one-way relaying. As such, it has been nominated as a solution to extend the coverage of links ...
Secrecy Analysis of Directional mmWave UAV-Based Links Under Hovering Fluctuations
(
IEEE
, 2023 , Article)
Recent developments in Unmanned Aerial Vehicles (UAVs) technology have paved the way to their utilization in different fields and applications. Among these applications, UAVs have been widely investigated as a good candidate ...
Optimal Trajectory and Positioning of UAVs for Small Cell HetNets: Geometrical Analysis and Reinforcement Learning Approach
(
IEEE
, 2023 , Article)
In this paper, a dynamic unmanned aerial vehicle (UAV)-based heterogeneous network (HetNet) equipped with directional terahertz (THz) antennas is studied to solve the problem of transferring massive traffic of distributed ...
