# gst: the auto assembly of a drop (from thermal capillary waves)

<< after single or multiple bridges form due to the presence of thermal capillary waves, the bridge growth commences in a thermal regime. Here, the bridges expand linearly in time much faster than the viscous-capillary speed due to collective molecular jumps near the bridge fronts. Transition to the classical hydrodynamic regime only occurs once the bridge radius exceeds a thermal length scale l_(T) ~ sqrt(Radius). >>

# brain: a pause (acyclic pauses?) approach to enhance and manage creativity

AA << find that participants  with quantity incentives outperform  the high creativity production of their fixed-pay counterparts only in the second-stage task, after the incubation period. Mediation analyses suggest that quantity-incentivized participants’ propensity to try more divergent ideas in the first stage sparks their creativity advantage in the second stage. >>

# brain behav: a hypothesis of 'loss of self' when they have to assume a 'fictional perspective'

In a functional MRI (Magnetic Resonance Imaging) study, AA << sought to identify brain regions preferentially activated when actors adopt a Fic1P (fictional first-person) perspective during dramatic role playing. >>

<< Compared to responding as oneself, responding in character produced global reductions in brain activity and, particularly, deactivations in the cortical midline network of the frontal lobe, including the dorsomedial and ventromedial prefrontal cortices. Thus, portraying a character through acting seems to be a deactivation-driven process, perhaps representing a 'loss of self'. >>

# ai.bot: adaptive robotics, the beginning

<< The goal of Zhao's lab is to create small, lightweight robots that can reconfigure themselves in response to a need. "In general, if you have a robot, its mechanical structure is fixed," says Zhao [Jianguo Zhao], an assistant professor in the Department of Mechanical Engineering. "If we can change the mechanical structure on the fly, without redesigning the robot, this is pretty useful, especially if the robot is very small … I don't think many people are trying to do that." >>
