A promising approach for scaling-up trapped-ion quantum computer platforms is by storing multiple trapped-ion qubit sets ('ion crystals') in segmented microchip traps and to interconnect these via physical movement of the ions ('shuttling'). Already

Stable system performance is mandatory to warrant the accuracy and reliability of biological results relying on small animal positron emission tomography (PET) imaging studies. This simple requirement sets the ground for imposing routine quality cont

Scanner sensitivity is often critical in high-resolution Positron Emission Tomography (PET) dedicated to molecular imaging. In neighboring pixelated detectors with individual readout, sensitivity decreases because of multiple coincidences produced by

Avalanche photodiode (APD) based positron emission tomography (PET) scanners show enhanced imaging capabilities in terms of spatial resolution and contrast due to the one to one coupling and size of individual crystal-APD detectors. However, to ensur

Optimal image quality in small animal positron emission tomography (PET) is critical to ensure accuracy and reliability of results obtained in biological studies. Indeed, unstable image quality over time can jeopardize longitudinal studies. This is w

High-resolution PET scanners with pixelated detectors have great sensitivity increase potential through the inclusion of multiple coincidences. Indeed, poor energy resolution and in-crystal detection mispositioning often prevent “traditional” Com

Sensitivity is critical in small-animal PET, and including more of the discarded detections would increase it. However lowering the energy threshold compromises the spatial resolution. This paper is an update on a method to include triple coincidence

Satellite attitude control based on state feedback techniques requires measurement of all the state variables describing the attitude dynamics. The Extended Kalman Filter (EKF) has been used for this task, and works quite well in the general cases. H
