Temporal modulation transfer functions in the European Starling (Sturnus vulgaris): II. Responses of auditory-nerve fibres [PDF]
, 1995 The temporal resolution of cochlear-nerve fibres in the European starling was determined with sinusoidally amplitude-modulated noise stimuli similar to those previously used in a psychoacoustic study in this species (Klump and Okanoya, 1991).

Stability of low-frequency fluctuation amplitudes in prolonged resting-state fMRI
NeuroImage, 2014 The (fractional) amplitudes of low-frequency fluctuations (f)ALFF are popular measures for the magnitude of low-frequency oscillations in resting-state fMRI (R-fMRI) data. Both measures can be directly derived from the spectral power of R-fMRI time courses.

Response analysis of 3D braided two-stage gear system excited by different frequency signals
Advances in Mechanical Engineering, 2021 The knitting principle of 3D braided gear was studied, and the dynamic model of the two-stage gear system was established. The fourth-order Runge-Kutta method was used to numerically simulate the dynamic characteristics of common gear and 3D braided gear.

Dynamic alterations of amplitude of low-frequency fluctuations in patients with chronic neck pain
Psychoradiology, 2021 Abstract Background The pathogenesis of neck pain in the brain, which is the fourth most common cause of disability, remains unclear. Furthermore, little is known about the characteristics of dynamic local functional brain activity in cervical pain ...

Large Amplitude, Low Frequency Plasma Fluctuations at Comet Giacobini-Zinner
Geophysical Research Letters, 1986 Very large amplitude fluctuations in electron density, temperature, and flow velocity were a prominent aspect of the solar wind interaction with comet Giacobini‐Zinner during the ICE encounter in September 1985. These fluctuations were detected at a distance of at least 9 × 105 km and grew in amplitude as ICE approached the comet, peaking in amplitude ...
