Research on a Wire Rope Breakage Detection Device for High-Speed Operation Based on the Multistage Excitation Principle

open access: yesSensors, 2023
Wire rope breakage, as damage easily produced during the service period of wire rope, is an important factor affecting the safe operation of elevators.

Computational Modeling of Contrast Sensitivity and Orientation Tuning in First-Episode and Chronic Schizophrenia

open access: yesComputational Psychiatry, 2017
Computational modeling is a useful method for generating hypotheses about the contributions of impaired neurobiological mechanisms, and their interactions, to psychopathology.

Simulation of a Power Transformer Differential Protective Relay [PDF]

open access: yesEngineering 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.

Hidden multiparticle excitation in weakly interacting Bose-Einstein Condensate

open access: yes, 2018
We investigate multiparticle excitation effect on a collective density excitation as well as a single-particle excitation in a weakly interacting Bose--Einstein condensate (BEC).

Interaction of Be4+ and Ground State Hydrogen Atom—Classical Treatment of the Collision

open access: yesAtoms, 2020
The interaction between Be4+ and hydrogen atom is studied using the three-body classical trajectory Monte Carlo method (CTMC) and the quasiclassical trajectory Monte Carlo method of Kirschbaum and Wilets (QTMC-KW).

Excitation control: balancing PSD-95 function at the synapse

open access: yesFrontiers in Molecular Neuroscience, 2008
Excitability of individual neurons dictates the overall excitation in specifi c brain circuits. This process is thought to be regulated by molecules that regulate synapse number, morphology and strength.

Excitation of Nucleon Resonances [PDF]

open access: yes, 2001
I discuss developments in the area of nucleon resonance excitations that are necessary to bring our understanding of nucleon structure in the regime of strong QCD to a qualitatively new level.

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

open access: yesFrontiers 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 ...

Plasticity during Sleep Is Linked to Specific Regulation of Cortical Circuit Activity

open access: yesFrontiers in Neural Circuits, 2017
Sleep is thought to be involved in the regulation of synaptic plasticity in two ways: by enhancing local plastic processes underlying the consolidation of specific memories and by supporting global synaptic homeostasis.

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

open access: yeseLife, 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 ...
