Super High-Selectivity Fifth-Order Bandpass Filter with Twelve Transmission Zeros [PDF]

Radioengineering, 2018
A fifth-order bandpass filter (BPF) with super high selectivity using three pairs of coupled lines and two open stubs is proposed. Twelve transmission zeros (TZs) from 0 to 2f_0 (f_0 denotes center frequency of the passband) and five transmission poles ...

Synthesis design of dual‐path coupled line circular ring resonator filter with tunable characteristic impedances and transmission zeros

IET Microwaves, Antennas & Propagation, 2021
A dual‐path coupled‐line circular ring resonator filter synthesis is presented. The topology comprises identical coupled lines in series duplicated to form dual‐path coupled‐line interconnections.

Nonlinear Model of Coupled Superconducting Lines [PDF]

IEEE Transactions on Appiled Superconductivity, 2005
High Temperature Superconductor materials are known to produce intermodulation and other nonlinear effects. In planar structures, these nonlinearities depend on the field configuration on the strip, which in turn strongly depends on the device structure and therefore on the coupling between the strips. In this work we present an equivalent circuit that

Carcinomas and Carcinoid Tumors of the Lungs and Bronchi in Children and Adolescents: The EXPeRT Recommendations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Primary lung carcinomas and bronchial carcinoid tumors (BC) are very rare malignancies in childhood. While typical BC and mucoepidermoid carcinomas are mostly low‐grade, localized tumors with a more favorable prognosis than in adults, necessitating avoidance of overtreatment, adenocarcinomas of the lung are often diagnosed at advanced disease ...

Power Divider Based on Broadside Slot-Coupled Lines [PDF]

Journal of Electromagnetic Engineering and Science
This paper proposes a power divider composed of a broadside slot-coupled line with microstrips located on the top and bottom surfaces, a ground plane slot at the center, and a resistor for improved isolation. Two- and four-way dividers are designed based

A Single-Layer Ultra-Wideband Dual-Channel Differential Phase Shifter Using Coupled Lines [PDF]

Iranian Journal of Electrical and Electronic Engineering, 2023
In this work, a broadband dual-channel differential phase shifter is developed with a small phase deviation across a wide frequency range. The design consists of two main lines for 45° and 90° phase shifts, along with a reference line.

Health‐Related Quality of Life and Symptom Severity Among Patients With PIK3CA‐Related Overgrowth Spectrum: A Mixed‐Methods Study to Understand Real‐World Experience With Alpelisib Treatment

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background PIK3CA‐related overgrowth spectrum (PROS) includes several rare overgrowth disorders resulting from somatic gain‐of‐function mutations in PIK3CA. Despite treatment advances, including the recent approval of alpelisib for PROS in the United States, literature detailing the patient experience with PROS is limited.

Venous Thromboembolism in Pediatric Bone Sarcoma Patients: A 10‐Year, Single‐Institution Experience Encompassing the COVID‐19 Pandemic

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Osteosarcoma (OS) and Ewing sarcoma (EWS) are the most common primary bone cancers in children, but acute thrombosis is poorly characterized in this population. Our study evaluated the rates of venous thromboembolism (VTE) and associated risk factors in pediatric patients with bone sarcomas treated over a 10‐year period encompassing
