Adherence to Protocol Recommendations for Children With Wilms Tumour in Two Consecutive Studies in the United Kingdom and Ireland—Does Variation Matter?

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background and Aims Wilms tumour (WT) has excellent event‐free and overall survival (OS). However, small differences exist between countries participating in the same international study. This led us to examine variation in adherence to protocol recommendations as a potential contributing factor.

Full-bridge modular multilevel converter (FB-MMC) with extended control range [PDF]

, 2015
This paper presents an attractive control scheme that decouples cell capacitor voltage regulation of the FB-MMC from the dc link voltage regulation. This is achieved by manipulating both ac and dc components of modulation functions.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Mathematical model of full-bridge voltage converter

Proceedings of Tomsk State University of Control Systems and Radioelectronics, 2023
The article presents the equivalent circuits and operation modes of a full-bridge static converter. A presented mathematical model of a voltage converter describes the operation of its elements and provides a study of power transformer magnetization. The results of mathematical and simulation modeling obtained in Matlab/Simulink and OrCAD are compared.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative
