This paper discusses multimodal affect detection from a fusion of facial expressions and interaction features derived from students' interactions with an educational game in the noisy real-world context of a computer-enabled classroom. Log data of students' interactions with the game and face videos from 133 students were recorded in a computer-enabled(More)
MOTIVATION With increasing availability of temporal real-world networks, how to efficiently study these data? One can model a temporal network as a single aggregate static network, or as a series of time-specific snapshots, each being an aggregate static network over the corresponding time window. Then, one can use established methods for static analysis on(More)
Since human aging is hard to study experimentally due to long lifespan and ethical constraints, current "ground truth" knowledge about human aging has mostly been <i>predicted</i> computationally or statistically by transferring the knowledge from well-studied model species via sequence homology or by studying human gene expression data. Since genes, i.e.,(More)
Current "ground truth" knowledge about human aging has been obtained by transferring aging-related knowledge from well-studied model species via sequence homology or by studying human gene expression data. Since proteins function by interacting with each other, analyzing protein-protein interaction (PPI) networks in the context of aging is promising. Unlike(More)
Structural aspects of the environment frequently influence the taxonomic and functional diversity of associated ecological communities. Spartina alterniflora and Phragmites australis both are structure-forming species in salt marshes but reciprocal invaders. Epifaunal communities on invasive Phragmites on the east coast of North America are reduced relative(More)
AIM To test changes in the phylogenetic relatedness, niche breadth, and life-history strategies of nematodes along a latitudinal gradient. LOCATION Sixteen wetland locations along the Pacific coast of China, from 20°N to 40°N. METHODS Linear regression was used to relate nematode phylogenetic relatedness (average taxonomic distinctness (AvTD) and(More)
Mind wandering (MW) is a ubiquitous phenomenon in which attention involuntarily shifts from task-related processing to task-unrelated thoughts. This study reports preliminary results of a video-based MW detector during film viewing. We collected training data in a study where participants self-reported when they caught themselves MW over the course of(More)
Human population growth and development have heavily degraded coastal ecosystems with cascading impacts across multiple trophic levels. Understanding both the direct and indirect trophic effects of human activities is important for coastal conservation. In New England, recreational overfishing has triggered a regional trophic cascade. Predator depletion(More)
In this study, a mix inexact-quadratic fuzzy water resources management model of floodplain (IQT-WMMF) has developed, through incorporating techniques of credibility-constrained programming (CP), two-stage programming (TP), interval-parameter programming (IPP) and quadratic programming (QP) within a general framework for limited data availability. The(More)
