Estimating Phase Amplitude Coupling between Neural Oscillations Based on Permutation and Entropy

open access: yesEntropy, 2021
Cross-frequency phase–amplitude coupling (PAC) plays an important role in neuronal oscillations network, reflecting the interaction between the phase of low-frequency oscillation (LFO) and amplitude of the high-frequency oscillations (HFO).

How Volatile is ENSO? [PDF]

open access: yes
The El Niños Southern Oscillations (ENSO) is a periodical phenomenon of climatic interannual variability which could be measured through either the Southern Oscillation Index (SOI) or the Sea Surface Temperature (SST) Index.

Thomson scattering of plasma turbulence on PSI-2

open access: yesNuclear Materials and Energy, 2017
The turbulent transport in the edge of fusion reactors can be conveniently simulated by linear plasma devices with long duty cycles. At high input power steady state plasma discharges at PSI-2 exhibit intermittent fluctuations similar to the edge of ...

Weighted bounded mean oscillation applied to backward stochastic differential equations

open access: yes, 2020
We deduce conditional -estimates for the variation of a solution of a BSDE. Both quadratic and sub-quadratic types of BSDEs are considered, and using the theory of weighted bounded mean oscillation we deduce new tail estimates for the solution on ...

Spatiotemporal Analysis of Extreme Temperature Change on the Tibetan Plateau Based On Quantile Regression

open access: yesEarth and Space Science, 2022
Temperature extremes have been extensively observed on the Tibetan Plateau (TP), of which the dynamics were mostly monitored by traditional trend analysis based on linear regression.

Conditional mutual information maps as descriptors of net connectivity levels in the brain

open access: yesFrontiers in Neuroinformatics, 2010
There is a growing interest in finding ways to summarise the local connectivity properties of the brain through single brain maps. Here we propose a method based on the conditional Mutual Information in the frequency domain.

Thermal explosion in oscillating ambient conditions [PDF]

open access: yesScientific Reports, 2016
AbstractThermal explosion problem for a medium with oscillating ambient temperature at its boundaries is considered. This is a new problem in thermal explosion theory, not previously considered in a distributed system formulation, but important for combustion and fire science. It describes autoignition of wide range of fires (such as but not limited to

Actuarial Implication of Structural Changes in El Niño-Southern Oscillation Index Dynamics [PDF]

open access: yes, 2017
The influence of climate variability on agricultural production and financial risks faced by an individual or an institution has been the center of the public discussion in the recent years.

Circadian clock regulator Bmal1 gates axon regeneration via Tet3 epigenetics in mouse sensory neurons

open access: yesNature Communications, 2023
Axon regeneration of dorsal root ganglia (DRG) neurons after peripheral axotomy involves reconfiguration of gene regulatory circuits to establish regenerative gene programs. However, the underlying mechanisms remain unclear.

Oscillations Conditions in Homogenous Systems [PDF]

open access: yesIFAC Proceedings Volumes, 2010
The problem of oscillations detection for nonlinear systems is addressed. The notion of homogeneity in bi-limit from (Andrieu, et al., 2008) is extended to local homogeneity. Next, sufficient conditions of oscillations existence for locally homogeneous systems are formulated.
