Binocular disparity,resulting from the differences between the retinal images of the two eyes,plays a fundamental role in the formation of stereoscopic vision and depth perception[1].Generally,a greater difference(disparity)between the two images indicates that the objects are closer to each other(Fig.1A).The brain uses binocular disparity to extract depth information from the two-dimensional retinal images,and the subtle differences between the images received by each eye allow us to perceive stereoscopic depth,which is important for the visual perception of the three-dimensional space[2].

The hot ductility of v-N and v-Nb microalloyed steels was investigated on a Gleeble-1500 thermomechanical simulator, and the results were compared with those of v and Nb microalloyed steels. A ductility trough is found in both the steels in the temperature range of 700 to 1050℃. Compared to the v steel, the v-N steel has a wider and deeper ductility trough with the increase of N content, due to the in- creased precipitation of v（C, N） in the steel. Above 930℃, when 0.047wt% v is added to the 0.028wt% Nb-containing steel, the ductility becomes worse, owing to the rise of the onset dynamic recrystallization temperature. However, the ductility gets better at 800 to 930℃ be- cause of the coarsening of precipitates in austenite. With the improvement in ductility, the fracture mechanism is changed from intergranular to high ductile fracture in the temperature range of 800 to 1050℃.

MicroRNAs （miRNAs） are a class of short non-coding RNA molecules that have attracted tremendous attention from the biological and biomedical research communities over the past decade. With over 1900 miRNAs discovered in humans to date, many of them have already been implicated in common human disorders. Facilitated by high-throughput genomics and bioinformatics in conjunction with traditional molecular biology techniques and animal models, miRNA research is now positioned to make the transition from laboratories to clinics to deliver profound benefits to public health. Herein, we overview the progress of miRNA research related to human diseases, as well as the potential for miRNA to becoming the next generation of diagnostics and therapeutics.
