The low noise phase of a 2d active nematic
, 2017 We consider a collection of self-driven apolar particles on a substrate that organize into an active nematic phase at sufficiently high density or low noise.

Meta‐analysis fails to show any correlation between protein abundance and ubiquitination changes
FEBS Open Bio, EarlyView.We analyzed over 50 published proteomics datasets to explore the relationship between protein levels and ubiquitination changes across multiple experimental conditions and biological systems. Although ubiquitination is often associated with protein degradation, our analysis shows that changes in ubiquitination do not globally correlate with changes in ...

The Low Noise Limit in Gene Expression
PLoS ONE, 2015 Protein noise measurements are increasingly used to elucidate biophysical parameters. Unfortunately noise analyses are often at odds with directly measured parameters. Here we show that these inconsistencies arise from two problematic analytical choices:

Compact Source of EPR Entanglement and Squeezing at Very Low Noise Frequencies [PDF]
, 2004 We report on the experimental demonstration of strong quadrature EPR entanglement and squeezing at very low noise sideband frequencies produced by a single type-II, self-phase-locked, frequency degenerate optical parametric oscillator below threshold ...

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 ...

Characterization of low-noise quasi-optical SIS mixers for the submillimeter band [PDF]
, 1996 We report on the development of low-noise quasi-optical SIS mixers for the frequency range 400-850 GHz. The mixers utilize twin-slot antennas, two-junction tuning circuits, and Nb-trilayer junctions. Fourier-transform spectrometry has been used to verify

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 ...

Low-Noise Techniques in Detectors [PDF]
Annual Review of Nuclear and Particle Science, 1988 We concentrate in this review on the fundamentals of low-noise techniques and on understanding the limits in the charge signal measurements. Charge collection and signal formation in detectors, the origin and properties of noise, noise and amplification of charge, and detectors and signal processing are discussed. (AIP)

Support assembly for cryogenically coolable low-noise choke waveguide [PDF]
, 1980 A compact cryogenically coolable choked waveguide for low-noise input coupling into a cryogenically cooled device, such as a maser or parametric amplifier, utilizes coaxial stainless steel support tubes surrounding the waveguide and connected in cascade ...

Experimental realization of a low-noise heralded single photon source
, 2010 We present a heralded single-photon source with a much lower level of unwanted background photons in the output channel by using the herald photon to control a shutter in the heralded channel.
