Contagion of fear: Is the impact of COVID-19 on sovereign risk really indiscriminate?
(Wiley, 2021)
This paper investigates the impact of infectious diseases on the evolution of sovereign credit default swap (CDS) spreads for a panel of 77 countries. Using annual data over 2004-2020, we find that infectious-disease ...
Discovering Customer Purchase Patterns in Product Communities: An Empirical Study on Co-Purchase Behavior in an Online Marketplace
(Mdpi, 2021)

The effect of weekend curfews on epidemics: a Monte Carlo simulation
(Tubitak Scientific & Technical Research Council Turkey, 2021)
The ongoing COVID-19 pandemic is being responded with various methods, applying vaccines, experimental treatment options, total lockdowns or partial curfews. Weekend curfews are among the methods for reducing the number ...
Increasing Energy Efficiency of WSNs Through Optimization of Mobile Base Station Locations
(IEEE, 2021)
In terms of enhancing overall energy usage, wireless sensor networks (WSNs) can run with minimal energy to extend their lifespan. Due to limited power resources, the optimal base station (BS) location could prolong the ...
Physical-Layer Security in 6G Networks
(IEEE-Inst Electrical Electronics Engineers Inc, 2021)
The sixth generation (6G) of mobile network will be composed by different nodes, from macro-devices (satellite) to nano-devices (sensors inside the human body), providing a full connectivity fabric all around us. These ...
Location Aware Vertical Handover in a VLC/WLAN Hybrid Network
(IEEE-Inst Electrical Electronics Engineers Inc, 2021)
Visible light communication (VLC) has emerged as a promising technology for wireless communication as it offers higher data rates and secure data transmission along with providing indoor illumination. However, VLC is ...
Exploring the Space-Calorie Association: Preliminary Evidence from Reaction Time Performance
(Univ Economics & Human Sciences Warsaw, 2021)
