Using a multi-longitudinal-mode (MLM) and a single-longitudinal-mode (SLM) all-solid-state green lasers to be the pumping sources of a continuous-wave Ti:sapphire laser, respectively, the intensity-noise dependence of the Ti:sapphire laser on the longitudinal-mode structure of pumping sources is experimentally studied. The comparison between the theoretical prediction based on the quantum-mecha...

[1] A number of synthesis activities, mathematical modeling, and experiments on dry deposition of aerosol‐sized particles over forested surfaces point to three disjointed findings: (1) deposition velocities measured over tall forests do not support a clearly defined minimum for particle sizes in the range of 0.1–2 mm; (2) when measurements of the normalized deposition velocity (Vd ) are present...

The employment of university graduates has always been a matter great concern to educational administrative departments and governments at all levels. EPI (employment prosperity index) is weather vane that reflects the situation labor market, it also an important reference for national economic situation. This paper constructs college students’ from different aspects, such as environment, emplo...

Recently, self-supervised pretraining of transformers has gained considerable attention in analyzing electronic medical records. However, systematic evaluation different tasks radiology applications using both images and reports is still lacking. We propose PreRadE, a simple proof concept framework that enables novel controlled environment. investigated three most-commonly used (MLM—Masked Lang...

Brain tumours are rooted by atypical and abandoned enlargement of brain cells, which are the subsequent source of death associated to cancer in less than 30 years age of people in recent years. Early stage diagnosing of these brain tumours will reduce the unconditional deaths of young people. For that the most suggested one of the finest expertises is Magnetic Resonance Imaging (MRI). In this w...

The structures and spectroscopic properties of Co(II), Ni(II), Cu(II), Zn(II) and Cd(II) nitrate complexes of 1-methyllumazine (MLM) and 1,6,7-trimethyllumazine (MLMD) with general formula M(II)(NO3)2L2 /nH2O are reported. In all the complexes, the lumazine-derived ligands seem to be coordinated in bidentate form through the N5 and O4 atoms. The crystal structures of [Cu(MLM)2(H2O)2](NO3)2 (1),...
