Dual-Band Suspended-Plate Wearable Textile Antenna [PDF]
IEEE Antennas and Wireless Propagation Letters, 2013 A novel, dual-band wearable textile antenna fabricated using conductive textiles for operation in both ISM and HiperLAN applications is presented. Its concept is based on the suspended-plate antenna. It features a 60 $\,\times\,$ 45 mm $^2$ rectangular radiating element suspended over a 80 $\,\times\,$ 60 mm $^{2}$ ground plane using a 5-mm

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations
Advanced Biology, Volume 9, Issue 3, March 2025.Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...

Tunable dual-band planar antenna
Electronics Letters, 2008 A dual-band antenna design that covers the 2.26-2.54 GHz and 5.14-6.10 GHz bands is presented. The proposed antenna design consists of two patch radiators suspended above a ground plane. The performance in the lower and upper bands can be controlled with less mutual coupling effect.
