Randomized gap and amplitude estimation [PDF]
Physical Review A, 2016 We provide a method for estimating spectral gaps in low-dimensional systems. Unlike traditional phase estimation, our approach does not require ancillary qubits nor does it require well characterised gates. Instead, it only requires the ability to perform approximate Haar-random unitary operations, applying the unitary whose eigenspectrum is sought out

FEBS Open Bio, EarlyView.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.

FEBS Open Bio, EarlyView.The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.

Algorithm supplement of four‐channel two‐target resolution for amplitude‐comparison monopulse radar
Electronics Letters, 2021 The traditional four‐channel monopulse two‐target resolution algorithm can only apply to phase‐comparison monopulse radars with four parallel beams and is not suitable for amplitude‐comparison monopulse radars with four squint beams.

Statistical Estimates of Amplitude and Phase Corrections [PDF]
Geophysical Journal International, 1970 Summary In seismology one frequently meets the problem of finding amplitude and phase corrections at one station relative to another, when there are errors of observation at both. This is a particular example of the following more general problem. We are given an input signal s(t) which passes through an unknown linear filter (black box) to give output

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments
FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...

On the Impact of Amplitude Variation on Interpolated DFT Method and How to Reduce It
Elektronika ir Elektrotechnika, 2018 The Interpolated DFT is often used to improve frequency estimation of the spectral lines of DFT’s spectrum. If the measured spectral line is distorted the accuracy of Interpolated DFT is decreased. Such distortion could be a result of amplitude variation

FEBS Open Bio, EarlyView.Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.
