To investigate the temporal-spatial distribution and evolutions of global Total Electron Content (TEC), we estimate the global TEC data from 1999 to 2013 by processing the GPS data collected by the International Global Navigation Satellite System (GNSS) Service (IGS) stations, and robustly constructed the TEC time series at each of the global 5°×2.5° grids. We found that the spatial distributio...

Tumour-specific chromosomal rearrangements are known to create chimaeric products with the ability to generate many human cancers. hTAF(II)68-TEC (where hTAF(II)68 is human TATA-binding protein-associated factor II 68 and TEC is translocated in extraskeletal chondrosarcoma) is such a fusion product, resulting from a t(9;17) chromosomal translocation found in extraskeletal myxoid chondrosarcomas...

Knowledge of the polar ionospheric total electron content (TEC) and its future variations is of scientific and engineering relevance. In this study, a new method is developed to predict Arctic mean TEC on the scale of a solar cycle using previous data covering 14 years. The Arctic TEC is derived from global positioning system measurements using the spherical cap harmonic analysis mapping method...

BACKGROUND AND OBJECTIVES T-cell lymphoblastic leukemia (T-ALL) cells originate within the thymus from the clonal expansion of T cell precursors. Among thymic stromal elements, epithelial cells (TEC) are known to exert a dominant inductive role in survival and maturation of normal, immature T-cells. In this study we explored the possible effect of TEC on T-ALL cell survival and analyzed the rol...

Abstract Timely, reliable and comprehensive global observation information is essential for space weather research. However, limited technology hinders the consecutive coverage of data. For integrity continuity data, deep learning can obtain a Ionospheric total electron content (TEC) map by fusing multi‐source TEC maps. Different from previous methods, in study, hybrid model (RFGAN) based on Du...

To test the impact of preheating (25, 37, 54, or 68 °C) of TetricEvoCeram (TEC), FiltekSupremeXT (FSXT), and Venus (V) on flexural strength (FS), shear bond strength (SBS) and interfacial tension (IFT). FS was tested with TEC and FSXT. For SBS, glass-ceramic and human dentin substrate were fabricated and luted with the preheated resin composite (RC). SBSs of 1500 thermal cycled specimens were m...

Thymocyte and thymic epithelial cell (TEC) development are interdependent processes. Although lineage relationships among progressively maturing thymocyte subsets have been characterized, the developmental relationships among TEC subsets are obscure. Because epithelial cells express distinct keratin (K) species as a function of differentiation stage and proliferative status, we used K expressio...
