We consider a catalytic branching Brownian motion with general branching which takes place only when particles are at the origin at a rate β>0 on the local time scale. We first establish a spine decomposition for the case wherein the particles have a positive probability of having no children. Then using this tool, we obtain results regarding the asymptotic behavior of the number of particles above λt at time t for λ>0. Under an L log L condition, we prove a strong law of large numbers for this catalytic branching Brownian motion.

The blend films with gelatin and poly（vinyl alcohol）（PVA） were prepared by a solution casting method. The compatibility between gelatin and PVA in the blend films was investigated. The transmittance, Fourier-transform infrared spectroscopy （FTIR）, x-ray diffraction （XRD）, thermogravimetry analysis （TG）, and differential scanning calorimetry （DSC） were employed to characterize the resultant blend films. According to optic result, the opacity of the blend film at the ratio of 20/80 （w/w, Gel to PVA） was the lowest, indicating the best compatibility between Gel and PVA at the ratio. The results oflR, XRD, DSC, and TG revealed an intensive interaction and good compatibility between them in the blend film at the ratio. The mechanical properties and solubility showed that PVA content in the blend films obviously affected the elongation at break and solubility. The mechanical properties and water resistance of gelatin film may be improved by the introduetion of PVA.

A novel layered nanocomposite was fabricated by the self-assembly of TiNbOs-nanosheets and 5,10,15,20- tetrakis（N-methylpyridinium-4-yl）porphyrinatocobalt（III）（CoTMPyP）. The product was characterized by a variety of analytical techniques such as XRD, EDX, Zeta potential, AFM, UV-vis, IR and SEM, the guest species were intercalated into the interlayer gallery of KTiNbO5 successfully. The electrochemical property of TiNbO5-CoTMPyP as an electrode modifying material was examined by cyclic voltammetry test in PBS solution （pH = 7）, and the hybrid exhibited excellent electrocatalytical property towards oxygen reduction with the peak potential shifting from -0.703 V （bare GCE） to -0.278 V （modified electrode）. The result also indicated that the oxygen molecule was reduced to H2O2 by a two-electron process.

An accurate understanding of the condition of a pipe is important for maintaining acceptable levels of service and providing appropriate strategies for maintenance and rehabilitation in water supply systems. Many factors contribute to pipe deterioration. To consolidate information on these factors to assess the condition of water pipes, this study employed a new ap-proach based on Bayesian configuration against pipe condition to generate factor weights. Ten pipe factors from three pipe ma-terials (cast iron, ductile cast iron and steel) were used in this study. The factors included size, age, inner coating, outer coating, soil condition, bedding condition, trench depth, electrical recharge, the number of road lanes, material, and operational pressure. To address identification problems that arise when switching from pipe factor information to actual pipe condition, informative prior factor weight distribution based on the literature and previous knowledge of water pipe assessment was used. The influence of each factor on the results of pipe assessment was estimated. Results suggested that factors that with smaller weight values or with weights having relative stable posterior means and narrow uncertainty bounds, would have less influence on pipe conditions. The model was the most sensitive to variations of pipe age. Using numerical experiments of different factor combinations, a simplified model, excluding factors such as trench depth, electrical recharge, and the number of road lanes, is provided. The proposed Bayesian inference approach provides a more reliable assessment of pipe deterioration.
