Most patients, post-amputation, report the experience of a phantom limb. Some even sense voluntary movements when viewing a mirror image of the intact limb superimposed onto the phantom limb. While delayed visual feedback of an action is known to reduce a sense of agency, the effect of delayed visual feedback on phantom motor sensation (i.e., sense of controlling a phantom limb) has not been ex...

We report noninvasive detection of spin coherence in a collection Raman-driven cold atoms using dispersive Faraday rotation fluctuation measurements, which opens possibilities probing correlations quantum gases and other similar systems. demonstrate five orders magnitude enhancement the measured signal strength as compared to traditional noise spectroscopy with thermal equilibrium. Our observat...

The silicon-vacancy (SiV) and germanium-vacancy (GeV) centers in diamond have a sharp photoluminescence with high brightness. In this work, the of these is measured up to 180 GPa using nanodiamonds integrated anvil cell. results show blueshifts mean emission energy determined by atomic radii impurity. agreement $a\phantom{\rule{0}{0ex}}b$ $i\phantom{\rule{0}{0ex}}n\phantom{\rule{0}{0ex}}i\phant...

The accurate description of phonons in a solid is one the central research topics field condensed matter physics and materials science. Here, authors report successful application $a\phantom{\rule{0}{0ex}}b$ $i\phantom{\rule{0}{0ex}}n\phantom{\rule{0}{0ex}}i\phantom{\rule{0}{0ex}}t\phantom{\rule{0}{0ex}}i\phantom{\rule{0}{0ex}}o$ quantum Monte Carlo (QMC) framework to phonon dispersion calculat...

After limb amputation, patients often wake up with a vivid perception of the presence of the missing limb, called "phantom limb". Phantom limbs have mostly been studied with respect to pain sensation. But patients can experience many other phantom sensations, including voluntary movements. The goal of the present study was to quantify phantom movement kinematics and relate these to intact limb ...

Introduction: One of the main steps in the optimization process in diagnostic imaging is the quality control of radiology devices. The usual method of CT scan calibration is used of a phantom. The phantom created a certain weakening for the radiation through which it passes. One of the most suitable methods for quantitative analysis of the resolution and contrast in CT scan im...
