In September 2015, the United Nations General Assembly accepted 2030 Development Agenda, which has included 92 paragraphs, and Paragraph 91 defined 17 sustainable development goals (SDGs) 169 associated targets. The goal of this paper is to discover correlations among SDGs information communications technologies (ICTs). This discusses roles opportunities that ICTs play in pursuing SDGs. We identify a number research gaps those three pillars, social, economic, environmental perspectives,...

Nowadays, at least two billion people are experiencing a complete lack of wireless cellular network coverage. These users live in rural areas and low-income regions, where operators not keen to invest, mainly due high capital expenditure operational costs, as well the scarcity electricity from grid. We tackle this challenge by proposing 5G explicitly designed serve areas. Our solution investigates possibility mounting remote radio heads on top unmanned aerial vehicles, large cells (LCs)...

In vitro 3D cancer spheroids (tumoroids) exhibit a drug resistance profile similar to that found in solid tumors. spheroid culture methods recreate more physiologically relevant microenvironments for cells. Therefore, these models are appropriate screening. We have recently developed protocol MCF-7 cell culture, and used this method test the effects of different types drugs on estrogen-dependent breast spheroid. Our results demonstrated cells can grow medium using low attachment plate....

Challenged Networks (CNs) are characterized by frequent varying network conditions and intermittent connectivity. In general, CNs emerge in different scenarios including the disaster emergency situations when traditional cellular infrastructure is dysfunctional or unavailable as well undeserved areas such rural developing regions. This paper aims to evaluate performance of a mobile edge adopting Unmanned Aerial Vehicles (UAVs) for CN scenarios. Specifically, we assume that UAVs can host...

Current trends in telecommunication networks foresee the adoption of fifth generation (5G) wireless near future. However, a large number people are living without coverage and connectivity. To face this issue, we consider possibility deploying 5G rural low-income zones. After detailing current state-of-the-art, main challenges that need to be faced. Moreover, define pillars follow order deploy such zones, as well proposal future network architecture.

Small cells (SCs) mounted on top of Unmanned Aerial Vehicles (UAVs) can be used to boost the radio capacity in hotspot zones. However, UAV-SCs are subject tight battery constraints, resulting frequent recharges operated at ground sites. To meet energy demanded sites, operator leverages a set Solar Panels (SPs) and grid connection. In this work, we demonstrate that both i) level throughput provided areas ii) amount is exchanged with by sites play critical role such UAV-aided cellular network....

In the advanced 5G and beyond networks, multi-access edge computing (MEC) is increasingly recognized as a promising technology, offering dual advantages of reducing energy utilization in cloud data centers while catering to demands for reliability real-time responsiveness end devices. However, inherent complexity variability MEC networks pose significant challenges computational offloading decisions. To tackle this problem, we propose proximal policy optimization (PPO)-based Device-to-Device...

Head and neck cancer affects millions worldwide. The risk factors are numerous, including smoking, alcohol consumption, human papillomavirus to name a few. While improved preventative, diagnostic, treatment methods have decreased mortality rates, the treatments (chemotherapy, radiotherapy, or surgery) often result in smell and/or taste impairments. These can impact quality of life during after treatment. A scoping review was performed understand current research future directions regarding...
