Does low frequency noise affect human mental performance?
To study the influence of low frequency noise (LFN) on mental performance and subjective well-being, 192 male subjects, categorised in terms of sensitivity to noise in general, and to LFN in particular, worked with four standardised ...

This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

We describe the design, schematics, and performance of a very low noise FET cascode input amplifier. This amplifier has noise performance of less than 1.2 nV/Hz and 0.25 fA/Hz over the 500 Hz to 50 kHz frequency range.

Low Frequency Noise and Its Assessment and Evaluation
The main aim of this paper is to present recent knowledge about the assessment and evaluation of low frequency noise and infrasound close to the threshold of hearing and the potential effects on human health.

Hyperosmotic stress triggers the relocation of the CFIm complex from the nucleus to the cytoplasm. This shift creates a nuclear ‘stoichiometric bottleneck’, limiting CFIm availability for mRNA processing. Consequently, specific mRNAs like NUDT21 and DICER1 undergo targeted 3′UTR shortening, demonstrating how spatial protein dynamics drive rapid ...
