Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

The Improved Quadrant Switching MCP–PID Electric Machine Speed Smooth Transition Algorithm for Forklift Lifting Hydraulic Drive

IET Power Electronics
As electric forklifts advance, the electric machine‐pump/motor control system is key to their lifting system due to high efficiency. Traditional systems struggle with quadrant switching in permanent magnet synchronous machines and pump coupling, causing ...

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

FEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Machine Learning‐Based Detection of Broken Bars in Dual Three‐Phase Induction Motors: Methodology and Experimental Validation

IET Electric Power Applications
Dual three‐phase induction motor drives are gaining attention in applications where reliability is a critical concern, such as automotive. Although the dual‐stator winding reduces the impact of stator phase failures, these motors remain susceptible to ...

RNA‐related functions of BRCA2 in transcription, replication, and genome stability

FEBS Letters, EarlyView.
Beyond its role in homologous recombination, BRCA2 regulates R‐loop homeostasis, DNA–RNA hybrid resolution, RNA polymerase II dynamics, and transcriptional activation. Disruption of any of these functions can contribute to genome instability, inflammatory signaling, and tumorigenesis. BRCA2 is a central tumor suppressor protein best known for its roles

Influence of parameters detuning on induction motor NFO shaft-sensorless scheme

Advances in Electrical and Computer Engineering, 2010
In this paper, the parameter sensitivity analysis of shaft-sensorless induction motor drive with natural field orientation (NFO) scheme is performed. NFO scheme calculates rotor flux position using the rotor flux vector reference only, does not require

Artificial molecular machines and motors—Design and control of nanoscale motion

FEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...
