Stability analysis of a self-cycling fermentation model with state-dependent impulse times
Cordova-Lepe, Fernando
; ; (2014)
A self-cycling fermenter is a batch fermenter subject to recurrent emptyings of liquid volume followed by the refilling withnew fresh substrate. This article construc ts a modified model of self-cycling fermenter, which ...

State-dependent TMS of inferior frontal and parietal cortices highlights integration of grip configuration and functional goals during action recognition
(2020)Understanding the object-directed actions of conspecifics not only implies recognition of the object (e.g., a pen) and processing of the motor components (e.g., grip configuration), but also identification of the functional ...

State-dependent tms over prefrontal cortex disrupts fear-memory reconsolidation and prevents the return of fear
(2020)Erasing maladaptive memories has been a challenge for years. A way to change fear memories is to target the process of reconsolidation, during which a retrieved memory transiently returns to a labile state, amenable to ...
