Doppler backscattering system can measure the perpendicular velocity and fluctuation amplitude of density turbulence with intermediate wavenumber. An eight-channel has been installed in Experimental Advanced Superconducting Tokamak (EAST), which probe eight different radial locations simultaneously by launching fixed frequencies (55, 57.5, 60, 62.5, 67.5, 70, 72.5, 75 GHz) into plasma. The quasi-optical consists circular corrugated waveguide transmission, a parabolic mirror, rotatable mirror...
Abstract In this article, we have derived the acoustic pressure and medium refractive index expressions in a homogeneous atmospheric perturbed by planar finite amplitude wave. wave perturbation, developed Laguerre–Gaussian vortex beam transmission model medium. We investigated effects of different source parameters on phase transmission, considering medium’s viscous effect. The results show that waves distort distribution At given distance, gradually increases with increasing distance. same...
The electron structures of cubic PbTe and substitutional defects are investigated using the state art pseudo-potential plane wave method, in framework density functional theory within generalized gradient approximation. structural dependent positron annihilation was calculated lifetimes bulk, Pb mono-vacancy, Te mono-vacancy Na atom substituting on were respectively. study provides evidence that positrons can distinguish between mono-vacancies situ doping. lifetime values found to be too...
The paper establishes a transmission model for Laguerre-Gaussian vortex beams in atmospheric turbulence that is affected by finite-amplitude acoustic waves (i.e. non-linear waves). This study examines the variations orbital angular momentum (OAM) properties of beam disrupted waves. It also explores effects source parameters, namely pressure amplitude and frequency, on spiral spectrum detection probability. results indicate impact OAM varies depending distance wave transmission. Moreover,...
Abstract Precise control and manipulation of neutral atoms are essential for quantum technologies but largely dependent on conventional bulky optical setups. Here, a multifunctional metalens that integrates an achromatic lens with large numerical aperture is demonstrated, quarter‐wave plate, polarizer trapping characterizing single Rubidium atoms. The simultaneously focuses beam at 852 nm collects single‐photon fluorescence 780 nm. A strong dependence the lifetime observed external bias...
肢带型肌营养不良症为一组临床及遗传异质性疾病，以进行性的骨盆带肌和肩胛带肌的无力及萎缩为主要临床特点。肢带型肌营养不良症多在青少年或成人起病，伴血清肌酸激酶正常至显著升高。该文报道1例肢带型肌营养不良症累及心脏的患者，通过基因学检测及家系调查，明确诊断，并结合文献，分析诊断依据、发病机制及治疗方案，以供临床借鉴。.
Abstract In this study, a set of experiments were carried out in 21-story full-scale building varying stairwell ventilation state to investigate the fire behavior and smoke temperature distribution stairwell. Results demonstrate that top vents has great influence on than bottom vents. The flame inclines with open during steady stage, while closed, it just tilts slightly side wall. mass loss rates attenuations closed are larger those open. addition, can cause reduction temperature. These...
