Benefits and Lessons Learned from the Sentinel-3 Tandem Phase [PDF]

open access: yesRemote Sensing, 2020
During its commissioning phase, the Copernicus Sentinel-3B satellite has been placed in a tandem formation with Sentinel-3A for a period of 6 months. This configuration allowed a direct comparison of measurements obtained by the two satellites.

Gas-Phase Fragmentation of Cyclic Oligosaccharides in Tandem Mass Spectrometry [PDF]

open access: yesMolecules, 2019
Modern mass spectrometry, including electrospray and MALDI, is applied for analysis and structure elucidation of carbohydrates. Cyclic oligosaccharides isolated from different sources (bacteria and plants) have been known for decades and some of them ...

Phase Tandem Low-Coherence Interferometry for Surface Vibration Measurements

open access: yesSensors
The development of optical methods for surface vibration measurements is currently of great interest. We propose a modified tandem low-coherence technique that utilizes the phase information of the low-coherence signal to detect surface vibrations.

Pathway-priming of intermediate phases in FACs-based wide-bandgap perovskites for Si tandem solar cells [PDF]

open access: yesNature Communications
Wide-bandgap (WBG) perovskite solar cells (PSCs) have emerged as promising candidates for tandem applications, despite potential instability induced by halogen components. Formamidinium-cesium (FACs)-based perovskites represent as an intrinsically stable

Relating Forest Biomass to TanDEM-X Mean Phase Height

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The Copernicus DEM is derived as a mean of TanDEM-X phase heights. It is known that there is an almost linear—but variable—relationship between phase height and above-ground biomass (AGB).

Computational Investigation of Multiple Oscillating Hydrofoils and its Effect on Thrust Augmentation [PDF]

open access: yesMATEC Web of Conferences, 2021
Previous investigations of flapping hydrofoils for the purpose of thrust production have been limited to one or two in tandem. Tandem foils were found to have superior performance because the performance of the aft foil was augmented by the vortices shed
