Development of the Phaseless Calibration Algorithm for a Digital Antenna Array

Inventions, 2023
In this paper, we will discuss a calibration algorithm for a digital antenna array that diagnoses its real performance. It can be applied at such stages of the antenna system life cycle as design, tuning, and especially maintenance.

PBPK modeling: What is the role of CYP3A4 expression in the gastrointestinal tract to accurately predict first‐pass metabolism?

CPT: Pharmacometrics & Systems Pharmacology
Gastrointestinal first‐pass metabolism plays an important role in bioavailability and in drug–drug interactions. Physiologically‐based pharmacokinetic (PBPK) modeling is a powerful tool to integrate these processes mechanistically.

Dynamic simulation of land-use changes in a periurban agricultural system [PDF]

, 2005
Studying the driving forces of land-use change dynamics (LUCD) is important for understanding the change process. A spatially explicit simulation model helps to test hypotheses about landscape evolution under several scenarios.
