A Novel Fully Integrated 4-Bit IFM Subsystem Using Band-Stop Filters
In this paper a 2-4 GHz microstrip IFM (Instantaneous Frequency Measurement) subsystem that uses Wilkinson power dividers, frequency discriminators based on band-stop filters and a DC arduino section is reported.

Weakening a theorem on divided powers [PDF]
We show that if a Hopf algebra has finite dimensional primitives and a primitive lies in arbitrarily long finite sequences of divided powers then it lies in an infinite sequence of divided powers. Introduction. K. Newman has shown us a counter-example to [3, Theorem 2, p. 521]. The theorem states that if H is a cocommutative Hopf algebra over a perfect

Abstract: The basic design of a power divider with two symmetrical quarter-wavelength branches that provide matching conditions at all of its ports is the focus of the research. Fr4 was chosen as the design's substrate, and 2.9 GHz is the operating frequency for the circuit.

Compact Unequal Power Divider with Filtering Response
We present a novel unequal power divider with bandpass responses. The proposed power divider consists of five resonators and a resistor. The power division ratio is controlled by altering the coupling strength among the resonators.

Harnessing the power of dividing cardiomyocytes
Lower vertebrates, such as newt and zebrafish, retain a robust cardiac regenerative capacity following injury. Recently, our group demonstrated that neonatal mammalian hearts have a remarkable regenerative potential in the first few days after birth.

Dual-band and tri-band balanced-to-single ended power dividers with wideband common-mode suppression [PDF]
A new design approach of developing multi-band balanced-to-single-ended (BTSE) power dividers is presented in this brief. The design is based on flexible coupling schemes which can guide designing multi-band balanced-to-single-ended power dividers with ...

Analytical Design for Full-space Spatial Power Dividers Using Metagratings
We present a rigorous theoretical framework for designing full-space spatial power dividers using metagratings. In our study, the current restrictions of spatial power dividing platforms such as reflection-only performance, operating at normal incidence,

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
