Spatial metabolic and phenotypic characterization of the germ-free mouse model. [PDF]

open access: yesAnn N Y Acad Sci
The germ‐free mouse model is a useful tool to understand the influence of the gut microbiota on host physiology. Using spatial metabolomics approaches we mapped the systemic location of small molecules in germ free and colonized mice, focusing on the intestine, spleen, lung, liver, and kidney.

Analysis of High-Frequency Common Mode Component Characteristics of Common Mode Peak Voltage Suppression Method for Indirect Matrix Converter

open access: yesEnergies, 2022
A variety of modulation strategies for suppressing output common-mode voltage (CMV) of indirect matrix converters (IMC) have been proposed, but most of them mainly reduce the peak of CMV by 42.3%. The frequency-domain characteristics of CMV have not been
