Retrieval of atmospheric parameters from GOMOS data [PDF]

Atmospheric Chemistry and Physics, 2010
The Global Ozone Monitoring by Occultation of Stars (GOMOS) instrument on board the European Space Agency's ENVISAT satellite measures attenuation of stellar light in occultation geometry.

Fast CCD Photometry in the Taiwan-America Occultation Survey

Open Astronomy, 2003
We describe the efforts of the Taiwan-America Occultation Survey (TAOS) project to develop a data acquisition and analysis scheme for fast CCD imaging photometry.

Variable anisotropy of small-scale stratospheric irregularities retrieved from stellar scintillation measurements by GOMOS/Envisat [PDF]

Atmospheric Measurement Techniques, 2014
In this paper, we consider possibilities for studying the anisotropy of small-scale air density irregularities using satellite observations of bi-chromatic stellar scintillations during tangential occultations.

Lunar Occultation Measurements of Stellar Angular Diameters [PDF]

Symposium - International Astronomical Union, 1997
Offering an angular resolution which has remained unattained by any other technique for decades, lunar occultations have traditionally been the most productive method for the measurement of stellar angular diameters. Unlike interferometric methods, which are limited in resolution by the size of the aperture or of the baseline between apertures, in a ...

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

FEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Equilibrium figure of Haumea and possible detection via stellar occultation

Astronomy & Astrophysics
We studied the equilibrium figure of dwarf planet Haumea to determine if the observed shape is compatible with a differentiated hydrostatic body. Three groups of interior models of Haumea were assumed, all with a rocky core and a volatile-rich outer ...

Retrievals from GOMOS stellar occultation measurements using characterization of modeling errors [PDF]

Atmospheric Measurement Techniques, 2010
In this paper, we discuss the development of the inversion algorithm for the GOMOS (Global Ozone Monitoring by Occultation of Star) instrument on board the Envisat satellite.

CEACAM1 participation in breast cancer progression

Molecular Oncology, EarlyView.
In invasive breast cancer (BC), CEACAM1 shifts from an apical to a uniform membranous/cytoplasmic pattern, or is lost, as tumors dedifferentiate, inversely tracking the Ki‐67 proliferative index. In MCF‐7 cells, only CEACAM1‐4L suppresses proliferation, repressing cell cycle and growth factor genes.

Influence of scintillation on quality of ozone monitoring by GOMOS [PDF]

Atmospheric Chemistry and Physics, 2009
Stellar light passing through the Earth atmosphere is affected by refractive effects, which should be taken into account in retrievals from stellar occultation measurements.
