A Parametric Six-Step Method for Second-Order IVPs with Oscillating Solutions

Mathematics
In this paper, we develop an explicit symmetric six-step method for the numerical solution of second-order initial value problems (IVPs) with oscillating solutions. The proposed method is phase-fitted and incorporates a free coefficient as a parameter to

Enhancing visual motion discrimination by desynchronizing bifocal oscillatory activity

NeuroImage, 2021
Visual motion discrimination involves reciprocal interactions in the alpha band between the primary visual cortex (V1) and mediotemporal areas (V5/MT).

Hydrodynamics of metachronal paddling: effects of varying Reynolds number and phase lag. [PDF]

R Soc Open Sci, 2019
Negatively buoyant freely swimming crustaceans such as krill must generate downward momentum in order to maintain their position in the water column. These animals use a drag-based propulsion strategy, where pairs of closely spaced swimming limbs are ...

Explicit two-step methods with minimal phase-lag for the numerical integration of special second-order initial-value problems and their application to the one-dimensional Schrödinger equation

, 1992
Two-step sixth-order methods with phase-lag of order eight, ten and twelve are developed for the numerical integration of the special second-order initial-value sproblem. An application to the one-dimensional Schrödinger equation on the resonance problem

Weighted phase lag index stability as an artifact resistant measure to detect cognitive EEG activity during locomotion

Journal of NeuroEngineering and Rehabilitation, 2012
Background High-density electroencephalography (EEG) with active electrodes allows for monitoring of electrocortical dynamics during human walking but movement artifacts have the potential to dominate the signal.

Population growth lags in introduced species

Ecology and Evolution, 2021
When introduced to new ecosystems, species' populations often grow immediately postrelease. Some introduced species, however, maintain a low population size for years or decades before sudden, rapid population growth is observed.

Dual-phase-lag thermoelastic damping models for micro/nanobeam resonators

, 2020
Thermoelastic damping (TED) affects the quality factors of vacuum-operated micro/nanobeam resonators significantly. In this work, by adopting the non-Fourier theory of dual-phase-lag (DPL) model, an analytical formula of TED in micro/nanobeam resonators ...

Zero-lag long-range synchronization of Hodgkin-Huxley neurons is enhanced by dynamical relaying : poster presentation

, 2007
Background The synchrony hypothesis postulates that precise temporal synchronization of different pools of neurons conveys information that is not contained in their firing rates.

Lymphocyte activation gene-3 : the expression and function in the immune system [PDF]

, 2006
Lymphocyte activation gene-3 (LAG-3) is the structural homologue of a well-known TCR co-receptor CD4. Recently, it has been suggested that LAG-3 might play a role in modulation of immune response, by being a negative regulator of T cell activation. To
