Inspired by the success of WaveNet in multi-subject speech synthesis,we propose a novel neural network based on causal convolutions for multi-subject motion modeling and *** network can capture the intrinsic characteristics of the motion of different subjects,such as the influence of skeleton scale variation on motion ***,after fine-tuning the network using a small motion dataset for a novel skeleton that is not included in the training dataset,it is able to synthesize high-quality motions with a personalized style for the novel *** experimental results demonstrate that our network can model the intrinsic characteristics of motions well and can be applied to various motion modeling and synthesis tasks.

The process of Sb2Te3 thin film growth on the Pt substrate by electrochemical atomic layer epitaxy (ECALE) was studied. Cyclic voltammetric scanning was performed to analyze the electrochemical behavior of Te and Sb on the Pt substrate. Sb2Te3 film was formed using an automated flow deposition system by alternately depositing Te and Sb atomic layers for 400 circles. The deposited Sb2Te3 films were characterized by XRD, EDX, FTIR and FESEM observation. Sb2Te3 compound structure was confirmed by XRD pattern and agreed well with the results of EDX quantitative analysis and coulometric analysis. FESEM micrographs showed that the deposit was composed of fine nano particles with size of about 20 nm. FESEM image of the cross section showed that the deposited films were very smooth and dense with thickness of about 190 nm. The optical band gap of the deposited Sb2Te3 film was determined as 0.42 eV by FTIR spectroscopy, and it was blue shifted in comparison with that of the bulk Sb2Te3 single crystal due to its nanocrystalline microstructure.

A turtle carapace bio-inspired Ti matrix hybrid composite was successfully fabricated in this work. This composite incorporates two parts： the Ti-Al intermetallic multilayered composite and continuous SiC fibers-reinforced Ti matrix composite. In the Ti-Al intermetallic multilayered composite part, a series of Ti-Al intermetallics compounds, including Ti3Al, TiAl, TiAl2 and TiAl3, were formed between the Ti layers. In the continuous SiC fibers-reinforced Ti matrix composite part, SiC fibers and Ti matrix were found to be bonded well through weak interface reaction. Flexural strength of this material reached 1.21 ±0.16 GPa, measured by three-point bending test. The deformation features suggest that the hierarchical structure combining ductile Ti layers/matrix with brittle high-strength Ti-Al intermetallics layers/SiC fibers can effectively enhance the mechanical properties of the bio-inspired hybrid composite.
