A novel preparation of aluminum diethylphosphinate（AlPi） was carried out with free-radical addition reaction by means of UV-irradiation under atmospheric pressure.A solution of sodium hypophosphite was treated with ethylene and irradiated with ultraviolet light in the presence of an amount of photoinitiator effective to initiate the free-radical reaction between the hypophosphite anion and the double bond of the ethylene *** ethylene was micro-bubbled into the reaction mixture with the addition of the photoinitiator,and the gas-liquid contact surface and the photoinitiator concentration in the gas-liquid interface were increased *** yield of the final product could be improved to about 96%.The contents of P,Al in samples were detected by ICP,and the molecular structure of the samples was confirmed by ^（31）P NMR,~1H NMR and FTIR spectroscopic *** stability of the final products was investigated in detail by TG-DTA.

With advanced prediction modes of intra prediction, intra coding of H.264/AVC offers significant coding gains compared with previous video coding standards. It uses an important tool called Lagrangian rate-distortion optimization (RDO)technique to decide the best coding mode for a block, but the computational burden is extremely high. In this paper, we proposed an improved fast intra prediction algorithm including block type selection and mode decision algorithm based on analysis of edge feature of a block. Our algorithm filters out unlikely block type and candidate modes to reduce the RDO calculations. Experimental results showed that the proposed algorithm can reduce the computation complexity of intra prediction from 52.90% to 56.31%, with 0.04 dB PSNR degradation and 2% increase of bit rate.

Microscopic polyangiitis （MPA） is characterized by an inflammatory process of the vessel walls and is classified according to the smallest vessels involved. Diagnosis is based on clinical manifestations, anti-neutrophil cytoplasmic autoantibody （ANCA） testing, and histology. In this disease, pulmonary hemorrhage is seen in 30% of patients and is associated with an eight-fold increase in mortality. Classically, MPA involves the kidneys and upper and lower respiratory tracts. Due to the perceived risk of increased bleeding secondary to the use of systemic anticoagulation, extra corporeal membrane oxygenation （ECMO） is often not used to treat patients with hemorrhage suffered from MPA. Here we report a case of a 50-year-old woman with MPA that was successfully supported with ECMO.

Single-cell omics: experimental workflow, data analyses and applications

In order to improve the utilization of unevenly distributed PM observations, a PM transport adjoint model is implemented to estimate the parameters and simulate PM over China. To increase the well-posedness, we use an independent point scheme(IPS) in experiments process. Twin experiments are used to test sensitive of the independent point(IP) and the observation noises to the adjoint model. The results manifest that the adjoint model can make well parameters inversion, and effectively improve the model ill-posedness caused by observation noises. In practical experiment, the simulated results can reproduce the spatio-temporal PM distributions, which supports the IPS effectiveness in the PM transport adjoint model.
