Differential absorption of exogenous and endogenous cholesterol in man

Journal of Lipid Research, 1983
Cholesterol absorption was measured in six patients by a triple-lumen intubation technique: 1) to determine whether isotopic exchange between radiolabeled lumenal cholesterol and unlabeled mucosal cholesterol occurs during cholesterol absorption ...

Solar Cell Detection and Position, Attitude Determination by Differential Absorption Imaging in Optical Wireless Power Transmission

Photonics, 2023
In optical wireless power transmission, position, size, and attitude of photovoltaic device (PV) must be determined from light source. A method proposed in the previous report is based on selective absorption characteristics of PV, and it is detected by ...

Positioning of a Photovoltaic Device on a Real Two-Dimensional Plane in Optical Wireless Power Transmission by Means of Infrared Differential Absorption Imaging

Photonics, 2023
In optical wireless power transmission (OWPT), detection and positioning of the photovoltaic device (PV) in real space is essential before power transmission. One of the candidates for the robust detection of PVs is differential absorption imaging, which

Influence of Absorption Cross-Sections on Retrieving the Ozone Vertical Distribution at the Siberian Lidar Station

Atmosphere, 2022
The purpose of this paper is to study how the application of different sets of absorption cross-sections influence the ozone vertical distribution (OVD) in the upper layers of the troposphere—stratosphere in the altitude range ~(5–45) km, using a ...

Development and Validation of an End-to-End Simulator and Gas Concentration Retrieval Processor Applied to the MERLIN Lidar Mission

Remote Sensing, 2021
In the context of MERLIN (MEthane Remote LIdar missioN), a French–German spatial lidar mission dedicated to monitoring the atmospheric methane content, two software programs have been developed: LIDSIM (LIDar SIMulator) and PROLID (PROcessor LIDar).
