Journal of Neurochemistry, Volume 168, Issue 7, Page 1193-1214, July 2024.Using spatial massspectrometry imaging in conjunction with multiplex mass cytometry imaging andimmuno‐histochemistry, disease related peri‐amyloid‐β plaque lipidomicdisruptions were captured in both mouse and human. These changes were subsequently colocalised with increased CD68 and LAMP1 upregulation.

The Effect of Antenna Place Codes for Reducing Sidelobes of SIAR and Frequency Diverse Array Sensors
IET Signal Processing, Volume 2024, Issue 1, 2024.Synthetic impulse and aperture radar (SIAR) is a technique that frequency diverse array (FDA) radars can imply in practice, thus overcoming some of their challenges. SIAR radars, used in various fields like transportation and defense, can detect the range, azimuth angle, elevation angle, and Doppler of the target with their 4D‐matched filter and a ...
