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.

Sleep Alters the Velocity of Physiological Brain Pulsations in Humans

Advanced Science, EarlyView.
Sleep alters I/CSF oscillatory flow, driven by increased respiratory (29%) and vasomotor pulsation (21%) velocities, while cardiovascular pulsations decreased by (22%). Velocity is quantified using optical flow analysis of MREG data. Spectral power increases alongside these pulsations (spatial correlation, r = 0.35 and r = 0.39, respectively ...

Rotational Doppler Effect of Vector Beams

Photonics
The optical rotational Doppler effect occurs when vortex beams are scattered by rotating objects and demonstrate the Doppler frequency shifts in scattered beams, which are associated with the optical angular momentum of vortex beams and the relative ...

Folded Chirp-Rate Shift Keying Modulation for LEO Satellite IoT

IEEE Access, 2019
In the low earth orbit (LEO) satellite Internet of Things (IoT), the IoT devices can be distributed in remote areas (e.g., desert, ocean, and forest) for some special applications, where they are unable to have direct terrestrial network accesses and can

Decoding Human Placental Cellular and Molecular Responses to Obesity and Fetal Growth

Advanced Science, EarlyView.
Women with obesity often deliver large‐for‐gestational‐age (LGA) infants. Single‐nucleus RNA sequencing of term placenta reveals that hypoxia and TNF‐α signaling in syncytiotrophoblasts are featured in maternal obesity, but inflammatory signatures in Hofbauer cells and response to lipid or carbohydrate metabolism in fibroblasts are specific to LGA.

Velocity-selective resonance dips in the probe absorption spectra of Rb D2 transitions induced by a pump laser

, 2004
We report experimental observation of velocity-selective resonances in the Doppler-broadened probe absorption spectra of 85Rb and 87Rb D2 transitions in the presence of a strong copropagating pump laser locked to a frequency within the Doppler profile of

TRIM56 Aggravates Cerebral Ischemia‐Reperfusion Injury via Inhibiting KLF4‐Activated Ferroptosis Signaling

Advanced Science, EarlyView.
This study reveals that the E3 ubiquitin ligase TRIM56 exacerbates neuronal ferroptosis and brain damage by mediating K48‐linked ubiquitination and degradation of KLF4, leading to suppression of the xCT/GSH/GPX4 axis. Targeting TRIM56 alleviates cerebral ischemia‐reperfusion injury in vivo and in vitro, highlighting its therapeutic potential.
