Integrated photonic power divider with arbitrary power ratios [PDF]
Optics Letters, 2017 Integrated optical power splitters are one of the fundamental building blocks in photonic integrated circuits. Conventional multimode interferometer-based power splitters are widely used as they have reasonable footprints and are easy to fabricate. However, it is challenging to realize arbitrary split ratios, especially for multi-outputs.

Compact Quasi-Planar Four-Way Power Divider With Wide Isolation Bandwidth
IEEE Access, 2019 A novel compact quasi-planar four-way power divider with a wide isolation bandwidth is proposed in this paper. The signal is fed through the coplanar waveguide and then divided to the four microstrip-line output ports through a metal via.

Compact Unequal Power Divider with Filtering Response
International Journal of Antennas and Propagation, 2015 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.

Calibration Method of a Wideband AC Resistance Voltage Divider Based on an Equivalent Model
Sensors, 2023 Aiming at the problem of large measurement error and phase shift in resistance voltage dividers under high-frequency conditions in the field of power measurement, such as power harmonics, an error correction method is proposed for an alternating current (

Constructing Sequences of Divided Powers [PDF]
Proceedings of the American Mathematical Society, 1972 In my Sequences of divided powers in irreducible, cocommutative Hopf algebras, I demonstrated the existence of extensions of sequences of divided powers over arbitrary fields, if certain coheight conditions are met. Here, I show that if the characteristic of the field does not divide n, every sequence of divided powers of length n 1, in a cocommutative

Results of the Childhood Cancer and Leukaemia Group's United Kingdom Relapsed Wilms Tumour Trial
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background The United Kingdom relapsed Wilms tumour (UKW‐R) trial aimed to improve the historically low survival rates after relapse of Wilms tumour (WT) through a prospective national risk‐stratified protocol. The trial also evaluated efficacy and toxicity of high‐dose melphalan.
