Journal ArticleDOI
Growth of carbon nanotubes by catalytic decomposition of CH4 or CO on a NiMgO catalyst
TL;DR: In this paper, the NiO and MgO components in this catalyst precursor formed, due to their highly mutual solubility, a NixMg1 − xO solid solution, and the high dispersion of Ni-species in this solid solution and the effect of valence-stabilization by the mgO crystal field would be in favor of inhibiting deep reduction of Ni2+ to Ni0 and aggregation of the Ni0 to form large metal particles at the surface of catalyst.
Journal ArticleDOI
A novel ECOC algorithm for multiclass microarray data classification based on data complexity analysis
TL;DR: A novel error correcting output code (ECOC) algorithm for the classification of multiclass microarray data based on the data complexity (DC) theory that can produce a compact ensemble system with high error correction capability through the application of diverse DC measures.
Journal ArticleDOI
Topic evolution based on LDA and HMM and its application in stem cell research
TL;DR: This paper analyses topic segmentation based on the LDA (Latent Dirichlet Allocation) model, and performs the topic segmentsation and topic evolution of stem cell research literatures in PubMed from 2001 to 2012 by combining the HMM (Hidden Markov Model) and co-occurrence theory.
Journal ArticleDOI
Implicit Reconstruction of Vasculatures Using Bivariate Piecewise Algebraic Splines
Qingqi Hong,Qingde Li,Jie Tian +2 more
TL;DR: Experimental results show that the geometric representation built using the proposed technique can faithfully represent the morphology and topology of vascular structures.
Proceedings ArticleDOI
Real-Time Eye-Gaze Based Interaction for Human Intention Prediction and Emotion Analysis
TL;DR: The methodology analyzes human emotion and cognition status from the aspect of eye-gaze behavior and head motion, understands the cognitive information that human eyes can express, and effectively improves the efficiency of human-computer interaction in different circumstances.
