On the Nature of Mixed Potential in a DMFC [PDF]
A ID + ID model of a direct methanol fuel cell (DMFC) is developed. Analytical solution for the case of equal oxygen and methanol stoichiometries X is obtained. The model predicts a new effect: formation of a narrow zone of local current (bridge), which "short-circuits" cell electrodes at vanishingly small current in the load.

Partially Different Mechanisms of Social and Nonsocial Attention: Evidence From Changes in Cueing Effects and Underlying Frontal Cortex Processing Over Time. [PDF]
ABSTRACT Gaze conveys important information about one's intentions and likely object of reference. Because processes of attention may change over time, for reasons including fatigue or experience, this study aimed to compare mechanisms of gaze and arrow cueing effects by measuring across sessions.

Neurofeedback-guided kinesthetic motor imagery training in Parkinson’s disease: Randomized trial
Background: Parkinson’s disease (PD) causes difficulty with maintaining the speed, size, and vigor of movements, especially when they are internally generated. We previously proposed that the insula is important in motivating intentional movement via its
