We present ShapeNet: a richly-annotated, large-scale repository of shapes represented by 3D CAD models of objects. ShapeNet contains 3D models from a multitude of semantic categories and organizes them under the Word-Net taxonomy. It is a collection of datasets providing many semantic annotations for each 3D model such as consistent rigid alignments, parts(More)

Cooperative communication has emerged as a promising technique to enhance system reliability and performances in resource-limited wireless networks. In this paper, we propose a novel cooperative MAC strategy for slow fading Ad hoc networks. Based on cooperative MAC (CMAC) protocol and node cooperative stop and wait (NCSW) ARQ protocol, our node-cooperative(More)
Individuals with autism spectrum disorder (ASD) are known to process faces atypically. However, there has been considerable controversy regarding whether ASD individuals also scan faces differently from typical adults. Here we compared ASD individuals' face-scanning patterns with those of typically developing (TD) controls and intellectually disabled (ID)(More)
Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by socio-communication impairments, and restricted and repetitive behaviors. Many individuals with ASD also have impairments in executive functioning skills (see Hill, 2004 for review), and thus have difficulty with tasks that require planning, organizing, inhibiting behavior,(More)
Large repositories of 3D shapes provide valuable input for data-driven analysis and modeling tools. They are especially powerful once annotated with semantic information such as salient regions and functional parts. We propose a novel active learning method capable of enriching <i>massive</i> geometric datasets with <i>accurate</i> semantic region(More)
Multimedia Mining is a young but challenging subfield in Data Mining. There are not unified conclusions in the concept, content and methods of Multimedia Mining, Multimedia mining architecture and framework has to be further studied. Based on these, it introduces a appropriate data mining model based on multimedia database; it has analyzed the methods which(More)
Wnt1, initially described as a modulator of embryonic development, has recently been discovered to exert cytoprotective effects in cellular models of several diseases, including Parkinson's disease (PD). We, therefore, examined the neuroprotective effects of exogenous Wnt1 on dopaminergic SH-SY5Y cells treated with 6-hydroxydopamine (6-OHDA). Here, we show(More)
There has been considerable controversy regarding whether children with autism spectrum disorder (ASD) and typically developing children (TD) show different eye movement patterns when processing faces. We investigated ASD and age- and IQ-matched TD children's scanning of faces using a novel multi-method approach. We found that ASD children spent less time(More)
Heme oxygenase (HO) catalyzes the rate-limiting step in heme catabolism to generate CO, biliverdin, and free iron. Two isoforms of HO have been identified in mammals: inducible HO-1 and constitutively expressed HO-2. HO-1 and HO-2 share similar physical and kinetic properties but have different physiological roles and tissue distributions. Unlike HO-1,(More)
