Advanced Science, EarlyView.This study primarily reveals that PM2.5‐derived Fe‐containing particles, particularly magnetite, are specifically enriched in the heart. Here, they interact with NCOA4 in endothelial cells, disrupt iron homeostasis by enhancing ferritinophagy, and subsequently trigger the process of EndMT through the NCOA4/KLF5 pathway.

The delta Doppler technique for LDV measurements at long distances [PDF]
A technique for measuring velocity, referred to as a Delta Doppler technique, was presented. This technique determines scattering source velocities by measuring the difference in Doppler shifts of two different frequencies.

Reverse Doppler effect in backward spin waves scattered on acoustic waves
, 2009 We report on the observation of reverse Doppler effect in backward spin waves reflected off of surface acoustic waves. The spin waves are excited in a yttrium iron garnet (YIG) film. Simultaneously, acoustic waves are also generated.

Advanced Science, EarlyView.The microbiota‐derived metabolite phenylacetylglutamine (PAGln) is elevated in type 2 diabetes and tightly associated with poor healing in both diabetic and non‐diabetic human patients. PAGln promotes mouse inflammation and impairs healing through a transmissible β2‐adrenergic receptor–mediated trained‐immunity loop.

A Micro-Doppler Modulation of Spin Projectile on CW Radar
ITM Web of Conferences, 2017 To obtain the spin speed of projectile effectively, a micro-Doppler modulation model of rotating projectile measured by continuous-wave radar (CW radar) is introduced.

The CO2 laser frequency stability measurements [PDF]
Carbon dioxide laser frequency stability data are considered for a receiver design that relates to maximum Doppler frequency and its rate of change. Results show that an adequate margin exists in terms of data acquisition, Doppler tracking, and bit error

Single‐Cell RNA Sequencing of Thyroid Tissues Reveals Pathogenesis of Graves' Disease
Advanced Science, EarlyView.Using single‐cell RNA sequencing and TCR profiling, this study constructed an immune cell atlas in thyroid tissue of Graves’ disease (GD), revealing dominant IFN‐γ‐secreting CD4+ T cells, expanded Tph and CD11c+ B cells, and enriched T/NK cells. Notably, GD thyroid follicular cells (TFCs) activated γδ T cells, which recruited cDC1 cells, suggesting a ...

Optical frequency standards for gravitational wave detection using satellite Doppler velocimetry
New Journal of Physics, 2015 Gravitational waves (GWs) imprint apparent Doppler shifts on the frequency of photons propagating between an emitter and detector of light. This forms the basis of a method to detect GWs using Doppler velocimetry between pairs of satellites. Operating in
