In addition to bulk thermodynamic experiments, scattering measurements can be used to probe microscopic fluctuations at length scales of the order of the probe wavelength λ. In a typical set up, a beam of wavevector ki is incident upon the sample and the scattered intensity is measured at wavevector ks = ki+q. For elastic scattering, |ki| = |ks| ≡ k, and q ≡ |q| = 2k sin θ, where θ is the angle...

Two-dimensional magic angle flipping (MAF) was employed to measure the Q(n) distribution in a 29Si enriched potassium disilicate glass (K2O · 2 SiO2). Relative concentrations of [Q(4)] = 7.2% ± 0.3%, [Q(3)] = 82.9% ± 0.1%, [Q(2)] = 9.8%± 0.6% were obtained. Using the thermodynamic model for Q(n) species disproportionation these relative concentrations yield an equilibrium constant k3 = 0.0103± ...

conclusions although some of the orthopedic surgeons are not interested to manage these fractures surgically and most of them treat these cases conservatively (casting, etc.), in most displaced intra-articular calcaneal fractures, surgical treatment is the method of choice. moreover, in non-surgical treatment the prevalence of these complications among the patients is more and as a result, inev...

We have studied the polarized image of an equatorial emitting ring around a 4D Gauss-Bonnet black hole. Our results show that effects parameter on depend magnetic field configuration, observation inclination angle, and fluid velocity. As lies in plane, observed polarization intensity increases monotonously with low angle case, its monotonicity disappears case high angle. However, as is vertical...

Bound states in the continuum (BICs) offer novel mechanisms to boost quality factor (Q-factor) of resonances. Unfortunately, current studies on chiral BICs metasurfaces suffer from a fundamental trade-off between Q-factor and circular dichroism (CD), presenting significant hurdle that severely limits independent control CD Q-factors. Here, 3D plasmonic are numerically demonstrated overcome high...

We investigated the excitation of terahertz (THz) surface magneto plasmons (SMPs) by nonlinear mixing laser and its second harmonic on a rippled n-type semiconductor-free space interface. Obliquely incident p-polarized lasers exert ponderomotive force free electrons semiconductor. Nonlinear induces oscillatory velocities at frequencies \(2\omega _{1}\) (\(\omega _{1}-\omega _{2}\)). These beat ...

The effects of passive head-up tilt on systolic time intervals were assessed in 18 patients with mitral valve prolapse. In addition to causing prolongation of the pre-ejection period and shortening of left ventricular ejection time, this circulatory stress led to progressive shortening of the Q to click interval. In 1 patient, a systolic click became audible which had not been heard in the supi...

Anisotropic particles are known to exhibit a richer and more complex phase behavior in comparison their spherical counterpart. While the majority of existing studies address structural properties, dynamic anisotropic is relatively lesser explored avenue. Using multispeckle ultra-small-angle x-ray photon correlation spectroscopy (USA-XPCS), we have carried out systematic investigation properties...

We show that the isotropic conductivity in the normal state of rare-earth tritelluride RTe3 compounds is broken by the occurrence of the unidirectional charge density wave (CDW) in the (a, c) plane below the Peierls transition temperature. In contrast with quasi-one-dimensional systems, the resistivity anomaly associated with the CDW transition is strong in the direction perpendicular to the CD...
