Engineered ETS1‐Nanoconjugate Restores Immune Homeostasis through Dual Immune‐Vascular Modulation in Relapsing and Progressive Multiple Sclerosis

Advanced Healthcare Materials, EarlyView.
The biomimetic nanoplatform IMNP (ETS1 pDNA/PBAE@ITP‐MM) undergoes targeted disassembly at inflammatory vascular sites to release the ETS1 plasmid (pETS1). This release initiates a cascade of effects that inhibit pathogenic pathways and support immune homeostasis. (Abbreviations: EndMT, endothelial‐to‐mesenchymal transition; EC, endothelial cell; TC, T

Triple-Passive Harmonic Suppression Method for Delta-Connected Rectifier to Reduce the Harmonic Content on the Grid Side

Applied Sciences
With the development of distributed energy sources such as photovoltaic and wind power, power grids have imposed increasingly higher requirements on power quality. As common nonlinear loads in power grids, multi-pulse rectifiers (MPRs) inject significant

Rate of equilibration of a one-dimensional Wigner crystal

, 2011
We consider a system of one-dimensional spinless particles interacting via long-range repulsion. In the limit of strong interactions the system is a Wigner crystal, with excitations analogous to phonons in solids. In a harmonic crystal the phonons do not

Research on Harmonic Suppression Methods

Highlights in Science, Engineering and Technology
Harmonics can be very harmful to power electronic equipment. With the widespread use of modern electronic equipment, the generation of harmonics has become more common. These harmonics not only come from non-linear loads but can also be caused by faults or instability in the power system.

Simple scheme for harmonic suppression by undulator segmentation

Journal of Synchrotron Radiation, 2002
In order to suppress harmonic intensity of undulator radiation, a scheme similar to the detuning technique used in the double-crystal monochromator is investigated and found to be effective only when the number of periods of the undulator is small, once the finite emittance of the electron beam and angular acceptance of the beamline are taken into ...

Machine-side Harmonic Suppression Strategy for Direct Driven Five-phase PMSG of Wind Power Generation System

Advances in Electrical and Computer Engineering
Wind power generation system with five-phase PMSG contains a large amount of third harmonic in the stator phase current of the machine side due to the dead-time effect of the converter and non-sinusoidal air-gap magnetic field.

Respiratory Organ‐on‐a‐Chip for Disease Modeling: From Architecture to Functional Integration

Advanced Healthcare Materials, EarlyView.
Respiratory organ‐on‐a‐chip (ROC) models capture key mechanical and cellular cues of the human respiratory system, enabling quantitative dissection of disease mechanisms. This review links ROC architectures to disease modeling, functional integration, and commercialization, and proposes a decision framework that aligns model complexity with mechanistic
