A Physical-Based Algorithm for Retrieving Land Surface Temperature From Moon-Based Earth Observation

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
Land surface temperature (LST) is a key parameter and plays an important role in hydrology, ecology, environment, and biogeochemistry. It is difficult for the existing satellites to acquire global LST with spatial and temporal consistency. The Moon-based

The different views from small angles [PDF]

open access: yesProceedings of the National Academy of Sciences, 2008
The small-angle scattering of x-rays or neutrons from proteins in solution can provide important information about the structure of the protein and the nature of interactions or distance correlations among the protein molecules (1, 2). The former is encoded in the form factor [P(q)], and the latter in the structure factor [S(q)]. These functions are of

Alignment of Viewing-Angle Dependent Ultrasound Images [PDF]

open access: yes, 2009
We address the problem of the viewing-angle dependency of ultrasound images for registration. The reflected signal from large scale tissue boundaries is dependent on the incident angle of the beam. This applies an implicit weighting on the ultrasound image, dependent on the viewing-angle, which negatively affects the registration process, especially ...

Effect of Viewing Angle in Gamma-Ray Burst Properties

open access: yesThe Astrophysical Journal
The empirical classification of gamma-ray bursts (GRBs) is based on their distribution in the plane of burst duration and spectral hardness. Two distinct distributions, long-soft and short-hard bursts, are observed in this plane, forming the basis for ...
