Degenerate cascade fluorescence: Optical spectral-line narrowing via a single microwave cavity

引用

Chinese Physics B 2021年第6期30卷 346-358页

作者： Liang hu xiang-Ming hu Qing-Ping hu College of Physical Science and Technology Central China Normal UniversityWuhan 430079China

For a three-level atom, two nondegenerate(even microwave and optical) electric dipole transitions are usually allowed;for either of these, the fluorescence spectra are well-described in terms of spontaneous transitions from a triplet of dressed sublevels to an adjacent lower-lying triplet. When the three dressed sublevels are equally spaced from each other, a remarkable feature known as degenerate cascade fluorescence takes place, which displays a five-peaked structure. We show that a single cavity can make all the spectral lines extremely narrow, whether they arise from cavity-coupled or cavity-free transitions. This effect is based on intrinsic cascade lasing feedback and makes it possible to use a single microwave cavity(even a bad cavity) to narrow the spectral lines in the optical frequency regime.

Robust 3D network architectures of MnO nanoparticles bridged by ultrathin graphitic carbon for high-performance lithium-ion battery anodes

Nano Research 2018年第2期11卷 1135-1145页

A strategy was developed to fabricate a set of MnO@C nanohybrids with MnO nanopartides （NPs） embedded in an ultrathin three-dimensional （3D） carbon framework for use as anode materials for lithium-ion batteries （LIBs）. The 3D carbon frameworks provide MnO NPs with electrical pathways and mechanical robustness, which efficiently improved the reaction kinetics, prevented the MnO from fracturing and agglomerating, and limited the formation of a solid electrolyte interface （SEI） at the MnO-electrolyte interface. Benefitting from the unique 3D framework structure, the MnO/C nanohybrids carbonized at 500 ℃ exhibited a highly reversible specific capacity of 1,420 mAh.g-1 at 0.2 A.g-1, excellent cycling stability with 98% capacity retention, and enhanced rate performance of 680 mAh-g-1 at 2 A.g-L The feasibility of the large-scale production of such MnO/C nanohybrids, associated with their outstanding Li-ion storage properties, opens a promising avenue for the development of high-performance anodes for next- generation LIBs.

A fast decoupled ISAR high-resolution imaging method using structural sparse information under low SNR

引用

Journal of Systems Engineering and Electronics 2019年第3期30卷 492-503页

作者： xiang Long LI Shaodong YANG Jun CHEN Wenfeng xiang hu Department of Air Defense Early Warning Equipment Air Force Early Warning Academy Wuhan 430019 China Unit 93253 of the PLA Dalian 116000 China

Inverse synthetic aperture radar (ISAR) image can be represented and reconstructed by sparse recovery (SR) approaches. However, the existing SR algorithms, which are used for ISAR imaging, have suffered from high computational cost and poor imaging quality under a low signal to noise ratio (SNR) condition. This paper proposes a fast decoupled ISAR imaging method by exploiting the inherent structural sparse information of the targets. Firstly, the ISAR imaging problem is decoupled into two sub-problems. One is range direction imaging and the other is azimuth direction focusing. Secondly, an efficient two-stage SR method is proposed to obtain higher resolution range profiles by using jointly sparse information. Finally, the residual linear Bregman iteration via fast Fourier transforms (RLBI-FFT) is proposed to perform the azimuth focusing on low SNR efficiently. Theoretical analysis and simulation results show that the proposed method has better performence to efficiently implement higher-resolution ISAR imaging under the low SNR condition.

Effects of External Electric Field on AlN Precipitation and Recrystallization Texture of Deep-drawing 08Al Killed Steel Sheet

引用

Journal of Materials Science & Technology 2006年第6期22卷 747-750页

作者： xiang ZHAO Zhuochao hu Liang ZUO Key Laboratory for Anisotropy Design and Texture Engineering of Materials （Ministry of Education） Northeastern University Shenyang 110004 China

The effects of an electric field on AIN precipitation and recrystallization texture were investigated. Cold-rolled 08Al killed steel sheets were annealed at 550℃ according to the two-step processes, for various maintaining times, with and without applying an electric field. It was found that the electric field promotes the precipitation of the second phase （AlN particles）, strengthens the γ-fiber and weakens the α-fiber texture component in the recrystallized specimens. A possible explanation for the reinforcement of γ-fiber texture by the electric field is that the second phase AIN particle promotes the growth of γ-fiber at the expense of differently oriented grains.

Prognostic prediction in gastric cancer patients without serosal invasion: comparative study between UICC 7^(th) edition and JCGS 13^(th) edition N-classification systems

引用

Chinese Journal of Cancer Research 2014年第5期26卷 596-601页

作者： xiang hu Liang Cao Yi Yu Department of General Surgery The First Affiliated HospitalDalian Medical University

Objective： T-stage and N-stage have been proven to be the most important factors influencing survival in gastric cancer patients, and have been accepted for use in the Japanese Classification of Gastric Carcinoma（JCGC） and the Union International Cancer Control（UICC-TNM） staging systems. The purpose of this study was to compare the prognostic values of the different N classification systems in gastric cancer patients without serosal ***： We retrospectively compared the clinicopathological results of 1,115 patients with primary gastric cancer who underwent curative gastric resection.Results： Serosal invasion was identified in 212 of 1,115 patients（19.0%）, and it was associated with lymph node metastasis according to the JCGC^13th（P〈0.001） and TNM^7th（P〈0.001） systems. The 5-year survival rate for the serosal invasion-negative patients（78.2%） was significantly higher than that for the serosal invasion-positive patients（31.1%）（P〈0.001）. Multivariate Cox regression survival analysis showed that depth of invasion（P=0.013）, 13 th JCGC PN stage（P〈0.001）, and 7th TNM PN stage（P〈0.001） were independent prognostic factors for serosal invasion-negative gastric cancer patients.Conclusions： The prognosis of gastric cancer patients with serosal invasion is very poor. Both the 13 th JCGC and 7th TNM N-staging systems were able to accurately estimate the prognosis of gastric cancer patients, but the 7th TNM system was simpler and easier to use.
