A Neuransistor with Excitatory and Inhibitory Neuronal Behaviors for Liquid State Machine

Advanced Materials, EarlyView.
The neuransistor integrates hybrid excitatory and inhibitory dynamics, enabling liquid state machine implementation. It operates via charge trapping in a two‐dimensional electron electron gas (2DEG)/TiO2−x structure and features a three‐terminal design for efficient masking functionality. Simulations demonstrate its effectiveness in predicting temporal

End-synapsis Assay

Bio-Protocol, 2013
Many environmental agents induce double-strand breaks (DSBs) in DNA. Unrepaired or improperly repaired DSBs can lead to cell death or cancer. Nonhomologous end joining is the primary DNA double-strand break repair pathway in eukaryotes.

Spike-timing-dependent-plasticity learning in a planar magnetic domain wall artificial synapsis [PDF]

arXiv
Future neuromorphic architectures will require millions of artificial synapses, making understanding the physical mechanisms behind their plasticity functionalities mandatory. In this work, we propose a simplified spin memristor, where the resistance can be controlled by magnetic field pulses, based on a Co/Pt multilayer with perpendicular magnetic ...
