Three-Phase Trinary Asymmetric Multilevel Inverter With Single DC Source and Open-Loop Control

IEEE Open Journal of Industry Applications, 2021
A three-phase trinary-asymmetric cascaded H-bridge multilevel inverter topology with single dc source per phase is presented in this paper. Only one of the H-bridges (called Main bridge) is fed from a dc source and all others (called auxiliary bridges ...

Modeling, Control and Experimental Investigation of a Cascaded Hybrid Modular Inverter for Grid Interface Application

IEEE Access, 2018
Research on modeling of cascaded hybrid modular inverters has concentrated on conventional H-bridge topologies. In addition, research on hybrid H-bridge that gives a five-level output voltage is well documented, but a detailed analysis on how this model ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

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
