Global plasmaspheric TEC and its relative contribution to GPS TEC

Journal of Atmospheric and Solar-Terrestrial Physics, 2008
The plasmaspheric electron content is directly estimated from the global positioning system (GPS) data onboard JASON-1 Satellite for the first time. Similarly, the ground-based GPS total electron content (TEC) is estimated using about 1000 GPS receivers distributed around the globe. The relative contribution of the plasmaspheric electron content to the

Thymic epithelial cell heterogeneity: TEC by TEC

Nature Reviews Immunology, 2019
The generation of a functional T cell repertoire in the thymus is mainly orchestrated by thymic epithelial cells (TECs), which provide developing T cells with cues for their navigation, proliferation, differentiation and survival. The TEC compartment has been segregated historically into two major populations of medullary TECs and cortical TECs, which ...

Comparison of global TEC between IRI TEC and GPS TEC in the spring of 2006

2017 XXXIInd General Assembly and Scientific Symposium of the International Union of Radio Science (URSI GASS), 2017
Comparison of the global Total Electron Content (TEC) derived from dual-frequency Global Positioning System (GPS) data and International Reference Ionosphere (IRI) used tomographic models, it has very important significance for IRI upgrading [1]. We investigate the trend of global TEC between IRI TEC and GPS TEC in the spring of 2006.

In this issue: Tec Kinases in the Crosshairs

International Reviews of Immunology, 2012
Tec family kinases are the second largest family of non-receptor tyrosine kinases, of critical importance to the biology of cells derived from the bone marrow. Significant progress in this area during the last decade revealed a role for several of these kinases in inflammatory and oncologic disorders.

Automatic TEC mapping using a GPS network and GIM-TEC

2015 1st URSI Atlantic Radio Science Conference (URSI AT-RASC), 2015
Ionosphere is an important layer of atmosphere, extending from 60 km to 1000 km altitude. The primary source of ionization is solar radiation. Yet, various factors from geomagnetic field to atmospheric structure complicate the ionization and recombination processes.

A new technique for TEC estimation

IEEE International Geoscience and Remote Sensing Symposium, 2003
A novel regularization technique which can combine signals from all GPS satellites for a given instant and given station, is developed to estimate the vertical total electron content values for the 24 hour period without missing any important feature in the temporal or spatial domain.
