Using novel simplified models of excitation for analytic description of initiation propagation and blockage of excitation waves [PDF]

, 2006
We consider applications of a recently suggested new asymptotic approach to detailed ionic models of cardiac excitation. First, we describe a three-variable approximation for the excitation fronts in a detailed ionic model of human atrial kinetics.

Benchmark Angle-Differential Cross-Section Ratios for Excitation of the 4p5s Configuration in Krypton

Atoms, 2021
Benchmark intensity ratio measurements of the energy loss lines of krypton for excitation of the 4p61S0→4p55s[3/2]2, 4p55s[3/2]1, 4p55s′[1/2]0, and 4p55s′[1/2]1 transitions are reported, these being the lowest electronic excitations for krypton.

Simulation of a Power Transformer Differential Protective Relay [PDF]

Engineering and Technology Journal, 2009
The aim of this work is to simulate a differential relay, which ensures security for external fault, inrush, and overexcitation conditions and provides dependability for internal faults, to protect a single phase power transformer.

Broadband and High-Efficiency Excitation of Spoof Surface Plasmon Polaritons Through Rectangular Waveguide

Frontiers in Physics, 2020
Spoof surface plasmon polaritons (SPPs) are highly localized surface waves that can be supported on metal surfaces with subwavelength decorations. Mode matching and momentum matching have been investigated so as to efficiently excite the spoof SPPs ...

Engram Excitement [PDF]

Neuron, 2019
Engram cells can encode and switch between multiple mnemonic functions, but how they intrinsically do so is unknown. Pignatelli, Ryan, and colleagues show that upon memory recall, the engram's excitability is transiently elevated, allowing its bearer to adapt to changing environments.

Intrinsic excitation-inhibition imbalance affects medial prefrontal cortex differently in autistic men versus women

eLife, 2020
Excitation-inhibition (E:I) imbalance is theorized as an important pathophysiological mechanism in autism. Autism affects males more frequently than females and sex-related mechanisms (e.g., X-linked genes, androgen hormones) can influence E:I balance ...

Model-Predicted Balance Between Neural Excitation and Inhibition Was Maintained Despite of Age-Related Decline in Sensory Evoked Local Field Potential in Rat Barrel Cortex

Frontiers in Systems Neuroscience, 2020
The balance between neural excitation and inhibition has been shown to be crucial for normal brain function. However, it is unclear whether this balance is maintained through healthy aging.

Reconstruction of the hydro generator excitation system on hydro power plant Trebinje 1 [PDF]

Tehnika, 2022
The excitation system of the hydro unit is a static self-excitation system that uses thyristor rectifiers in a three-phase fully controllable bridge connection with a digital two-channel regulation system characterized by a very fast response (eng.
