Low phase noise microwave frequency synthesizer for cold atom clock
AIP Advances, 2019 We present a low phase noise microwave frequency synthesizer for the integrating sphere cold atom clock. The synthesizer is based on an ultralow-phase-noise oven-controlled crystal oscillator and employs a phase-locking technique.

, 2021 Until now, Low-frequency noise (LFN) is hardly recognized as an environmental stressor, and its consequences on daily functioning have been rarely investigated. LFN is predominantly produced by human-made sources, and due to the increasing industrialization, these sources and accordingly the number of LFN complaints is steadily rising.

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Low frequency noise in advanced Si bulk and SOI MOSFETs
Journal of Telecommunications and Information Technology, 2005 A review of recent results concerning the low frequency noise in modern CMOS devices is given. The approaches such as the carrier number and the Hooge mobility fluctuations used for the analysis of the noise sources are presented and illustrated through

Low-frequency noise from large wind turbines [PDF]
The Journal of the Acoustical Society of America, 2011 As wind turbines get larger, worries have emerged that the turbine noise would move down in frequency and that the low-frequency noise would cause annoyance for the neighbors. The noise emission from 48 wind turbines with nominal electric power up to 3.6 MW is analyzed and discussed.

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies
FEBS Open Bio, EarlyView.We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Noise Annoyance and Perception by Low-Frequency Noise in Students
Archives of Occupational Health, 2019 Background: Low-frequency noise as a detrimental occupational and environmental factor which can cause noise annoyance. In addition to noise, factors such as sensitivity and awareness of adverse health effects of noise seem to play an important role in ...

Study and Assessment of Low Frequency Noise in Occupational Settings
Archives of Acoustics, 2015 Low frequency noise is one of the most harmful factors occurring in human working and living environment. Low frequency noise components from 20 to 250 Hz are often the cause of employee complaints.

Colored noise in the fractional Hall effect: duality relations and exact results
, 1999 We study noise in the problem of tunneling between fractional quantum Hall edge states within a four probe geometry. We explore the implications of the strong-weak coupling duality symmetry existent in this problem for relating the various density ...
