Dynamic cluster structure for object detection and tracking in wireless ad-hoc sensor networks
TLDR
We propose a dynamic cluster structure to track the movement of boundaries and facilitate the fusion and dissemination of boundary information in a sensor network. Expand

Domain-independent text segmentation using anisotropic diffusion and dynamic programming
TLDR
This paper presents a novel domain-independent text segmentation method, which identifies the boundaries of topic changes in long text documents and/or text streams by segmenting text in variable numbers of sentence topical groups. Expand

The effects of incubation thermal environments on size, locomotor performance and early growth of hatchling soft-shelled turtles, Pelodiscus sinensis
We incubated eggs of the soft-shell turtle (Pelodiscus sinensis) at constant (ranging from 23 � Ct o 34 � C) and fluctuating temperatures (varying from 22.3 � C to 32.8 � C) to assess influence ofExpand

The thermal dependence of food assimilation and locomotor performance in southern grass lizards, Takydromus sexlineatus (Lacertidae)
Abstract We collected southern grass lizards, Takydromus sexlineatus , from a population in Shaoguan (Guangdong, southern China), and used adult males and non-reproductive females to study theExpand

Identifying sources of variation in reproductive and life-history traits among five populations of a Chinese lizard (Takydromus septentrionalis, Lacertidae)
Research on life-history traits of squamate reptiles has focused on North American species, while Asian taxa have been virtually ignored. In order to understand general patterns in reptile lifeExpand

Splice site prediction using support vector machines with a Bayes kernel
TLDR
In this paper, we present a new machine learning method for predicting DNA splice sites, which first applies a Bayes feature mapping (kernel) to project the data into a new feature space and then uses a linear Support Vector Machine (SVM) as a classifier to recognize the true splICE sites. Expand

Multi-labelled classification using maximum entropy method
TLDR
In this paper, we explore correlations among categories with maximum entropy method and derive a classification algorithm for multi-labelled documents. Expand
