Low frequency cultural noise [PDF]
Geophysical Research Letters, 2009 Abnormal cultural seismic noise is observed in the frequency range of 0.01–0.05 Hz. Cultural noise generated by human activities is generally observed in frequencies above 1 Hz, and is greater in the daytime than at night. The low‐frequency noise presented in this paper exhibits a characteristic amplitude variation and can be easily identified from ...

Low-noise Yb:CALGO optical frequency comb
Optics Express, 2021 We report on a compact optical frequency comb, operating in the wavelength range from 670 to 1500 nm, based on diode-pumped low-noise femtosecond Yb:CALGO amplified laser system. Both the carrier-envelope offset and repetition rate are phase-locked to reference synthesizers. A full characterization of the frequency comb, in terms of frequency stability,

Constant and switched bias low frequency noise in p-MOSFETs with varying gate oxide thickness [PDF]
, 2002 The low-frequency noise power spectral density of MOSFETs is decreased if the MOSFETs are periodically switched 'off' (switched bias conditions). The influence of the gate oxide thickness on fixed bias and switched biased low frequency drain current ...

A Proposal for Risk Assessment of Low-Frequency Noise in the Human–Machine–Environment System
Applied Sciences, 2023 Low-frequency noise, the frequency range from approximately 10 Hz to 200 Hz, has been recognized as a special environmental noise problem. The World Health Organization recognizes the special place of low-frequency noise as an environmental problem ...

The X-ray fast-time variability of Sco X-2 (GX 349+2) with RXTE [PDF]
, 2001 Sco X-2 (GX 349+2) is a low-mass X-ray binary and Z source. We have analysed 156 ks of Rossi X-ray Timing Explorer data, obtained in 1998 January, on this source. We investigated the fast-time variability as a function of position on the Z track.
