The size of an organism reflects its metabolic rate, growth rate, mortality, and other important characteristics; therefore, the distribution of body size is a major determinant of ecosystem structure and function. Body-size distributions often are multimodal, with several peaks of abundant sizes, and previous studies suggest that this is the outcome of niche separation: species from distinct p...

The concept of change simply entails the totality of ways in which a particular entity has grown better and grown worse. Five studies suggest that this is not how people actually understand it for themselves. Rather, when asked to assess how they have "changed" over time, people bring to mind only how they have improved and neglect other trajectories (e.g., decline) that they have also experien...

Clustering categorical sequences is currently a difficult problem due to the lack of an efficient representation model for sequences. Unlike the existing models, which mainly focus on the fixed-length tuples representation, in this paper, a new representation model on the variablelength tuples is proposed. The variable-length tuples are obtained using a pruning method applied to delete the redu...

Mobile wireless video delivery is still challenging due to its limited bandwidth and dynamic channel status. In this paper, a novel approach named Dubbing Video Slides (DVS) is proposed to cope with the bandwidth limitation problem. Based on a statistical video content importance analysis, DVS method can dynamically select and transmit representative video frames which are relatively more impor...

We propose a new descriptive complexity notion of uniformity for branching programs solving problems defined on structured data. We observe that FO[=]-uniform (n-way) branching programs are unable to solve the tree evaluation problem studied by Cook, McKenzie, Wehr, Braverman and Santhanam [8] because such programs possess a variant of their thriftiness property. Similarly, FO[=]-uniform (n-way...
