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.

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...

Purpose: In longitudinal oncological and brain PET/CT studies it is important to understand the repeatability of quantitative PET metrics in order to assess change in tracer uptake or binding. The present studies were performed in order to assess the aspects of PET/CT repeatability related to reconstruction settings, analysis methods, scan duration (or image noise) and position in the field of ...

In this paper, we investigated the anisotropic thermal transport in two-dimensional (2D) perovskite (phenethylammonium lead iodide) nanolayers through a measurement technique called cross-sectional scanning microscopy. method, target layer on substrate was oblique polished with an Ar ion beam to create low-angle wedge nanoscale roughness that is followed by high-vacuum microscopy obtain conduct...

PURPOSE To evaluate multiparametric MRI features in predicting pathologic response after preoperative chemoradiation therapy (CRT) for locally advanced rectal cancer (LARC). EXPERIMENTAL DESIGN Forty-eight consecutive patients (January 2012-November 2014) receiving neoadjuvant CRT were enrolled. All underwent anatomical T1/T2, diffusion-weighted MRI (DWI) and dynamic contrast-enhanced (DCE) M...
