Global-Local Interference Is Related to Callosal Compromise in Alcoholism: a Behavior-DTI Association Study
We used a global–local paradigm to assess component processes of visuospatial ability and MR diffusion tensor imaging (DTI) to examine whether alcoholism-related microstructural degradation of the corpus callosum contributes to…

Learning Discriminative Sequence Models from Partially Labelled Data for Activity Recognition
We propose a new approach based on partially-supervised training of discriminative sequence models such as the conditional random field (CRF) and the maximum entropy Markov model (MEMM).

Opioidergic Projections to Sleep-Active Neurons in the Ventrolateral Preoptic Nucleus
We hypothesized that the influence of opiates on sleep may be mediated, at least in part, by the ventrolateral preoptic nucleus (VLPO), a key cell group for producing behavioral sleep.

The optimal throughput order of wireless ad hoc networks and how to achieve it
In this paper, we study the contribution of network coding (NC) in improving the multicast capacity of random wireless ad hoc networks when nodes are endowed with multi-packet transmission (MPT)…

A general framework for the capacity analysis of wireless ad hoc networks
In this paper, we introduce a general framework for computing the throughput capacity of wireless ad-hoc networks under all kinds of information dissemination modalities.
