A Quadruped Piezoelectric Ultrasonic Actuating Robot with Foot‐Leg‐Trunk‐Integrated Structure

Advanced Robotics Research, EarlyView.
This study proposes a novel foot‐leg‐trunk‐integrated quadruped piezoelectric ultrasonic actuating robot with small size and lightweight. A hybrid vibration mode combining the first‐order out‐of‐plane bending vibration of the trunk and the first‐order horizontal bending vibration of driving legs is designed to generate elliptical trajectories at foot ...

Why should we correct reported pulsation frequencies for stellar line-of-sight Doppler velocity shifts?

, 2014
In the age of Kepler and Corot, extended observations have provided estimates of stellar pulsation frequencies that have achieved new levels of precision, regularly exceeding fractional levels of a few parts in $10^{4}$.

Magnetic field orientation effect on specific heat in a p-wave superconductor

, 2006
The effect of magnetic field on specific heat of a p-wave spin triplet superconductor has been analyzed. To describe superconductivity we used a single band model with various realizations of p-wave order parameter and analyzed the effect of a Doppler ...

Anisotropic Surface Microrollers for Endovascular Navigation: A Computational Analysis with a Case Study in Hepatic Perfusion

Advanced Theory and Simulations, EarlyView.
Computational fluid dynamics analyses assess the upstream locomotion performance of anisotropic microrollers with varying height‐to‐width ratios. Observing their successful upstream locomotion in veins, their performance in hepatic circulation is investigated for treating primary liver cancer.

Lightlike simultaneity, comoving observers and distances in general relativity

, 2006
We state a condition for an observer to be comoving with another observer in general relativity, based on the concept of lightlike simultaneity. Taking into account this condition, we study relative velocities, Doppler effect and light aberration.

Loss of NR2F6 Protects from Salmonella Typhimurium Infection

Advanced Science, EarlyView.
Loss of nuclear receptor NR2F6 reduces tissue‐resident macrophage populations. Nr2f6‐deficient mice are protected from weight loss and bacterial load during infection with Salmonella Typhimurium. Pro‐inflammatory cytokines and iron levels are altered in infected Nr2f6‐deficient mice.

Interference Pattern Caused by Bilateral Bone Conduction Stimulation Impairs Sound Localization

Advanced Science, EarlyView.
This work explores how crosstalk‐induced wave interference affects bone conduction (BC) sound localization. Using a theoretical model, cadaveric vibrometry, and psychoacoustic tests, atypical BC lateralization patterns are revealed that contradict air conduction (AC) principles.
