In a multi-cell network, interference management between adjacent cells is a key factor that determines the performance of the entire cellular network. In particular, in order to control inter-cell interference while providing a high data rate to users, it is very important for the base station (BS)...

Sound insulation of the finite double-panel structure (DPS) inserted with a cylindrical shell array is investigated by varying the sound incidence direction to improve its applicability. The effects of the vibro-acoustic characteristics of its constituents on the sound transmission loss (STL) are es...

In this paper, the proposed wideband compact planar antenna is realized by incorporating multiple curved transmission lines along with the interdigital capacitor (IDC) and the electric inductor–capacitor (ELC) resonator. Furthermore, this antenna implements an asymmetric coplanar waveguide (ACPW) vi...

We propose an all-optical virtual private network (VPN) supporting dynamic bandwidth allocation (DBA) in an orthogonal frequency division multiple access-based passive optical network. A microwave photonic bandpass filter (MP-BPF) is used to transmit the VPN signal without electrical conversion. The...

Plummer-Vinson syndrome (PVS) is a complex condition characterized by a classic triad of dysphagia, iron deficiency anemia (IDA), and an upper esophageal web. Dysphagia represents the most important symptom of PVS and is usually observed with solid food. Therapeutic options for dysphagia include iro...
