Noise performance of frequency- and phase-locked CW magnetrons operated as current-controlled oscillators. [PDF]
, 2005 Low-power continuous wave ``cooker'' magnetrons driven from industrial-quality switch-mode power supplies have been frequency locked by driving them as current-controlled oscillators in a phase-lock loop (PLL).

Electronic Noise Measurement of a Magnetoresistive Sensor: A Comparative Study
SensorsThe intrinsic noise of giant magnetoresistive (GMR) sensors is large at low frequencies, and their resolution is inevitably significantly limited. Investigation of GMR noise requires the use of measurement systems that have lower noise than the sample ...

Experimental Characterisation of the Low Frequency Noise Annoyance Arising from Industrial Plants
, 1992 Complaints about low frequency noise annoyance are frequently reported although the sound levels, measured according to usual procedures, do not seem to justify such reactions.

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Low-Frequency Seismic Noise Properties in the Japanese Islands
Entropy, 2021 The records of seismic noise in Japan for the period of 1997–2020, which includes the Tohoku seismic catastrophe on 11 March 2011, are considered. The following properties of noise are analyzed: The wavelet-based Donoho–Johnston index, the singularity ...

Low-Frequency Noise Characteristics of AlGaAs/InGaAs Pseudomorphic HEMTs [PDF]
, 2001 The low-frequency noise of InGaAs pseudomorphic HEMTs fabricated on GaAs substrate was studied. The dependence of the noise spectral density on the gate voltage indicates that the channel of the device dominates the low-frequency noise.

Investigating transcription factor dynamics in health and disease using FRAP
FEBS Letters, EarlyView.FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Data-Driven Modeling of Low Frequency Noise Using Capture-Emission Energy Maps
Applied Sciences, 2020 A new approach for modeling low frequency noise is presented to enable the predictions of noise behavior from negative bias temperature instability (NBTI). The noise model is based on a capture-emission energy (CEE) map describing the probability density
