Engineering Reports, Volume 8, Issue 7, July 2026.A compact printed wide‐slot antenna with a diamond‐shaped tuning stub and parasitic elements achieves an ultrawide impedance bandwidth of 256% (2.4–16.2 GHz). Its capacitive nature enables frequency shifts with dielectric variations, making it highly suitable for accurate, non‐invasive glucose sensing applications.

On The Energy Efficiency of Adaptive WBAN Systems for mHealth Services
EAI Endorsed Transactions on Pervasive Health and Technology, 2017 We recently proposed an adaptive Wireless Body Area Network (WBAN) system for mHealth service, which shows better bit error performance compared to the non-adaptive one. However, analysis and maximization of the energy efficiency as one of the key design

A Dynamic Model for Extreme Hourly Precipitation
Environmetrics, Volume 37, Issue 3, April 2026.ABSTRACT Despite the scarcity of comprehensive studies at a global scale, many regional analyses report increases in extreme hourly precipitation values. The growing interest in assessing trends in extreme hourly precipitation has outpaced the development of new statistical tools tailored to their features. Typical analyses employ Extreme Value Theory (
