Voltage-programmable liquid optical interface [PDF]

, 2009
Recently, there has been intense interest in photonic devices based on microfluidics, including displays and refractive tunable microlenses and optical beamsteerers, that work using the principle of electrowetting.

Improved Super-Twisting Sliding Mode Control for Hybrid Three-Phase Converter Based on Finite-Time Observer

IEEE Access
This article proposes a finite-time extended state observer-based improved super-twisting sliding mode control (FTESO-ISTSMC) framework for three-phase hybrid converters to achieve enhanced dynamic response and strong anti-disturbance robustness. A novel

Spectral characteristics of voltage-sensitive indocyanine green fluorescence in the heart

Scientific Reports, 2017
Indocyanine green (ICG) fluorescent dye has been approved by the FDA for use in medical diagnostics. Recently, we demonstrated that ICG dye has voltage-sensitive properties with a dual-component (fast and slow) response in the Langendorff-perfused rabbit

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

System level dynamic voltage resilience index for assessment of large-disturbance voltage stability in renewable-rich power systems

Energy Conversion and Management: X
The large-scale integration of renewable generations, predominantly inverter-based resources (IBRs), has introduced significant challenges to power system stability, including voltage instability and collapse, due to their distinct dynamic and control ...

Dynamic and static performance optimization of dual active bridge DC-DC converters

Journal of Modern Power Systems and Clean Energy, 2017
High efficiency and fast dynamic response are two main control objectives for dual active bridge (DAB) DC-DC converters. Traditional extended phase shift (EPS) control can significantly enhance the conversion efficiency of DAB DC-DC converters by ...

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 ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.
