TL;DR: In this article, the authors used a coupled Lagrangian particle method combining a multi-phase δ-SPH scheme and a Total-Lagrangian-Particle (TLP) method.
Abstract: The present work is dedicated to an accurate modeling of violent Fluid-Structure-Interaction (FSI) problems using a coupled Lagrangian particle method combining a multi-phase δ-SPH scheme and a Total-Lagrangian-Particle (TLP) method. Advanced numerical techniques, e.g. Adaptive-Particle-Refinement (APR), have been included in the particle method for improving the local accuracy and the overall numerical efficiency. On one hand, this paper aims to demonstrate the capability of the proposed numerical method in modeling FSI flows with large density-ratios, strong fluid impacts, complex interfacial evolutions and considerable wall-boundary movements and deformations; On the other hand, the numerical results presented in this paper show the importance of considering the existence of air-phase in some complex FSI problems. The entrapped air-bubble, after the free-surface rolling and closing, plays an important role in the overall flow evolution and hence the hydrodynamic load on the structure. Although a density ratio as large as 1000 has been adopted, clear and sharp multi-phase interfaces, which undergo violent breakups and reconnections, are present in the numerical results, and more importantly, stable and smooth pressure fields are obtained. This contributes to an accurate prediction of the structural response, as validated by both the experimental data and other numerical results.

TL;DR: A robust Gaussian approximate fixed-interval smoother for nonlinear systems with heavy-tailed process and measurement noises is proposed and results show the efficiency and superiority of the proposed smoother as compared with existing smoothers.
Abstract: In this letter, a robust Gaussian approximate (GA) fixed-interval smoother for nonlinear systems with heavy-tailed process and measurement noises is proposed. The process and measurement noises are modeled as stationary Student’s t distributions, and the state trajectory and noise parameters are inferred approximately based on the variational Bayesian (VB) approach. Simulation results show the efficiency and superiority of the proposed smoother as compared with existing smoothers.

TL;DR: In this paper, a one-step reduction approach using copper (II) acetate as precursor in triethylene glycol solution at reaction temperature ranging from 100 to 180°C was used to synthesize sub-microspheres for H 2 S sensors.
Abstract: Cu 2 O/CuO sub-microspheres were synthesized via a one-step reduction approach using copper (II) acetate as precursor in triethylene glycol solution at reaction temperature ranging from 100 to 180 °C. It is found that the reaction temperature plays a very important role in the size, the Cu 2 O content, and morphology of the products. The sub-microspheres obtained at the reaction temperature below 140 °C are assembled by smaller particles with a diameter of about 10 nm. As the reaction temperature is increased to above 160 °C, uneven samples with larger size will be synthesized. The sensing performances of the sub-microspheres are related to the Cu 2 O content, porous characteristics and their surface areas. The sensor response of the sub-microspheres obtained at 120 °C is up to 2.1–50 ppb H 2 S gas at 95 °C, and the recovery time is only about 76 s. Thus, the sub-microspheres are promising for H 2 S sensors.

TL;DR: A novel and facile synthesis route to large-pore mesoporous nanocrystalline anatase thin films with tunable pore diameters in narrow distribution of sizes ranging from 8.3 to 14 nm is reported, using triblock copolymer as the template and Ti(OBu(n)4 as the inorganic precursor.
Abstract: A novel and facile synthesis route to large-pore mesoporous nanocrystalline anatase thin films with tunable pore diameters in narrow distribution of sizes ranging from 8.3 to 14 nm is reported, using triblock copolymer as the template and Ti(OBun)4 as the inorganic precursor. The obtained materials were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and nitrogen adsorption. A reasonable formation mechanism is also presented in this work.
