Detrended Fluctuation Analysis: A Scale-Free View on Neuronal Oscillations

open access: yesFront. Physio., 2012
Recent years of research have shown that the complex temporal structure of ongoing oscillations is scale-free and characterized by long-range temporal correlations.

On pooling networks and fluctuation in suboptimal detection framework

open access: yes
Motivated by biological neural networks and distributed sensing networks, we study how pooling networks – or quantizers – with random thresholds can be used in detection tasks.

open access: yes, 2014
. Linear and nonlinear response theory are developed for stationary Markov systems describing systems in equilibrium and nonequilibrium. Generalized fluctuation theorems are derived which relate the response function to a correlation of nonlinear ...

The magnetostatic relations including fluctuation fields

open access: yes, 1983
The influences of the fluctuation fields are important in many astrophysical environments as shown by the observations, and can not be neglected.

Sleep-wake cycle and diurnal fluctuation of amyloid-β as biomarkers of brain amyloid pathology

open access: yesScience Translational Medicine, 2012
Decreased sleep and attenuation of circadian fluctuations in Aβ reflect amyloid-associated pathology in Alzheimer’s disease. Don’t Let Amyloid Keep You Awake at Night The accumulation in the brain of the neurotoxic β-amyloid (Aβ) peptide is a key event ...

Energetics of quantum vacuum friction. II. Dipole fluctuations and field fluctuations: Dipole fluctuations and field fluctuations [PDF]

open access: yes, 2022
Quantum vacuum friction experienced by an atom, where the only dissipative mechanism is through its interaction with the radiation field, has been studied in our recent paper [Phys. Rev. D 104, 116006 (2021)PRVDAQ2470-001010.1103/PhysRevD.104.116006].

Nonequilibrium Period with Emergence of Marangoni Circulations in Meniscus Splitting

open access: yesAdvanced Materials Interfaces
Capillarity and Marangoni effect are important mechanisms driving interfacial pattern formation in dissipative structures of viscous fluids. “Meniscus splitting” pattern, a self‐assembly phenomenon in polysaccharide dispersions that occurs at the ...

Basic frequency analysis on period fluctuations of rhythms produced by humans for their enjoyment

open access: yesMechanical Engineering Journal, 2015
It is necessary to examine comfortable vibrations and swinging motions used in the development of a human-machine interface. Although the present study was limited to the rocking motion of a rocking chair, it was confirmed that the waveform of a swinging

Fluctuation Microscopy in the STEM

open access: yesMicroscopy and Microanalysis, 2001
Abstract Fluctuation microscopy is an electron microscopy technique sensitive to medium-range order (MRO) in disordered materials. It has been applied to study amorphous germanium and silicon, leading to the conclusion that these materials exhibit more MRO than the conventional continuous random network model for their structure.
