A Gut‐Brain Axis Underlying Succinate‐Associated Compulsive‐Like Behavior
Advanced Science, EarlyView.Gut‐derived succinate is associated with an excitatory‐inhibitory imbalance in dmPFC glutamatergic neurons, involving microglial SUCNR1 activation and vagal afferent signaling via upregulated gut 5‐HT4 receptors along the DVC‐CeA‐dmPFC circuit, changes that are linked to excessive compulsive‐like behavior.

Advanced Science, EarlyView.Field‐driven active colloids are framed as distributed micromachines in which externally supplied power, sensing, and control regulate task‐relevant states. By closing the loop between particle behavior, imaging, computation, and electric or magnetic actuation, these systems can progress from programmable motion toward adaptive functional outcomes ...

Power factor correction using boost converter technique / Nur Zati Akmar Lukeman [PDF]
, 2013 This project describes a single phase rectifier with improved power factor by using the boost converter technique. Low Power Factor (PF) is caused by nonlinearity of the input current. An active power factor correction method was designed for improvement
