FEBS Open Bio, EarlyView.Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Angle-of-Arrival Estimation in Large-Scale Hybrid Antenna Arrays
, 2023 Large-scale hybrid antenna arrays are able to leverage array gains, transceiver sizes, and costs for massive multiple-input-multiple-output (MIMO) communications in the millimeter-wave and terahertz frequency bands.

Application of Kalman Filtering Approach on Signal Angle-of-Arrival Estimates
2023 31st Signal Processing and Communications Applications Conference (SIU), 2023 This study focuses on modifying the Kalman Filtering (KF) approach, whose measurement noise suppression capability had been proven many times, especially in multidimensional positioning problems, to serve one-dimensional signal angle-of-arrival (AoA) measurements, and examining the overall AoA estimation performance.

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 ...

Phase‐difference measurement‐based angle of arrival estimation using long‐baseline interferometer
IET Radar, Sonar & Navigation, 2023 This article presents a direction‐finding method based on phase difference measurement for wide‐ranging applications of electronic intelligence. By including three processing steps of rotating, re‐scaling, and rounding of phase plane, the proposed method

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.
