Characterization of the key membrane protein cytochrome Cyc2 from Ghiorsea bivora
This study reports the first detailed biochemical analysis of Cyc2TAG1_1, a cytochrome protein involved in microbial iron oxidation. We produced and purified this enzyme in E. coli, then measured its iron‐oxidizing efficiency, and characterized its electrical and structural properties.

Power scaling of novel fibre sources
This thesis explores novel fibre-based coherent light source architectures and strategies for scaling output power. The research focuses on fibre-based amplified spontaneous emission (ASE) sources with broadband output in the ~1 µm spectral region and on

Low-power PFC and forward converters : methods to improve performance [PDF]
The number of power electronic appliances is growing. Power electronic converters can be used to convert the ac line voltage to a dc voltage, and further through dc-dc conversion stages to desired dc voltages for different loads.

An adaptive switched capacitor strategy for efficiency optimization in LLC converters
LLC resonant converters typically achieve high efficiency only within specific operating conditions. When working in high voltage conversion ratio scenarios, the switching frequency range increases, causing the efficiency to decline.

A series-parallel load-resonant converter for a controlled-current arc-welding power supply [PDF]
A power supply incorporating a series-parallel load-resonant converter, capable of very efficient operation over a wide range of output power is presented. The series-parallel load-resonant converter is shown to have three pairs of resonant frequencies.

ABSTRACT Objective Down syndrome regression disorder is a syndrome characterized by subacute loss of cognitive, behavioral, and functional abilities in individuals with Down syndrome. Electroencephalography abnormalities are frequently observed during evaluation, but it remains unclear whether these findings represent a dynamic marker of disease ...

T1 Over Squared Proton Density Ratio to Characterize Multiple Sclerosis Lesions
ABSTRACT Objective Differentiating remyelinated from demyelinated lesions in MS remains challenging without histological confirmation. This study introduces the T1‐to‐PD2 ratio (TPR) imaging approach and evaluates its ability to characterize MS lesions alongside other quantitative MRI (qMRI) metrics. Methods Thirty individuals with MS (mean age: 47.5 ±

Resonant Converters for Electric Equipment Power Supply
The paper deals with the use of resonant converters for the power supply of electric equipment. After exploring the advantages of using the resonant conversion, an analysis of the three main resonant topologies, namely i) series-resonant, ii) parallel ...
