Core Loss of MgZn Ferrite.

Journal of the Japan Society of Powder and Powder Metallurgy, 1999
The effects of substitution of Mn2O3 for Fe2O3 Or CuO for MgO in MgZn ferrite have been studied in order to achieve low core loss, focusing on the microstructure, the initial permeability and the resistivity of MnZn, MnMgZn, and MnMgCuZn ferrites.Initial permeability and resistivity of both MnMgZn and MnMgCuZn ferrites are higher than those of MgZn ...

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Modeling Frequency-Dependent Core Loss of Ferrite Materials Using Permeance–Capacitance Analogy for System-Level Circuit Simulations

IEEE transactions on power electronics, 2019
Ferrite core materials are preferred for magnetic components in power electronic converters considering their low cost and high permeability. Thanks to their negligible electrical conductivity, core loss is dominated by the frequency-independent ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

Molecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Radiation hydrodynamical simulations of eruptive mass Loss from progenitors of Type Ibn/IIn supernovae

, 2020
Observations suggest that some massive stars experience violent and eruptive mass loss associated with significant brightening that cannot be explained by hydrostatic stellar models. This event seemingly forms dense circumstellar matter (CSM).

Towards Standardized Magnetic Components Under Power Electronics Excitation With User-Friendly Loss Maps

IEEE Open Journal of Power Electronics
Nowadays, in a power electronics system, most components such as power electronics devices (MOSFETs, IGBTs, etc.) and capacitors are standardized, i.e., sold as a whole standard item with various values and ratings.
