Weak electric fields detectability in a noisy neural network.

This modeling study examines how a noisy spiking neural network detects a weak applied electric field using an Izhikevich neuron framework with excitatory/inhibitory neurons and conduction delays. The authors report stochastic resonance driven by white noise that enhances detectability, and that this effect largely…

Suppression of unimolecular decay of laser desorbed peptide and protein ions by entrainment in rarefied supersonic gas jets under weak electric fields.

This engineering-focused paper reports the design principle and performance of a MALDI ion source ("MALDI-2") combining rarefied supersonic gas jets with weak electric fields and injection into gas-filled RF multipoles. The abstract reports rapid collisional cooling (

Intestinal MMC-related electric fields and pancreatic juice control the adhesion of Gram-positive and Gram-negative bacteria to the gut epithelium--in vitro study.

This in vitro study tested whether a weak electric field reconstructed from duodenal spiking potentials during an MMC cycle affects bacterial adhesion to Caco-2 intestinal epithelial cells. The MMC-related electric field increased adhesion of Lactobacillus and Lactococcus strains, while two pathogenic strains…
