Modulation Scheme for the Bidirectional Operation of the Phase-Shift Full-Bridge Power Converter

IEEE Transactions on Power Electronics, 2020
This paper proposes a novel modulation technique for the bidirectional operation of the Phase Shift Full Bridge (PSFB) DC/DC power converter. The forward or buck operation of this topology is well known and widely used in medium to high power DC to DC converter applications.

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

FEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

FEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Metastatic niche shaped by host factors influences disseminated cancer cell fate

FEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Hardware Evaluation for GaN-Based Single-Phase Five-Level Inverter

IEEE Access, 2023
This study aims to assess the performance of Gallium Nitride (GaN)-based inverters in high-power applications through simulations and a hardware-in-the-loop experiment. The focus is on the efficacy of GaN-based inverters for multilevel topologies, a five-

Smaller is better: nanobodies meet NMR

FEBS Letters, EarlyView.
Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.

A Pulse Width Modulation-Based Sliding Mode Controller for Phase-Shifted Full-Bridge Converter With Diodes in Series on the Lagging Leg

IEEE Access
The typical strategy for the phase-shifted full-bridge (PSFB) converter is to design a linear compensator based on a small-signal model. However, this approach cannot provide a strongly robust output under changing operating conditions or with ...
