PPP-RTK is integer ambiguity resolutionenabled precise point positioning. In this contribution, we present the principles of PPP-RTK, together with a review of different mechanizations that have been proposed in the literature. By application of S-system theory, the estimable parameters of the different methods are identified and compared. Their interpretation is essential for gaining a proper ...
The successive events that cells experience throughout development shape their intrinsic capacity to respond and integrate RTK inputs. Cellular responses to RTKs rely on different mechanisms of regulation that establish proper levels of RTK activation, define duration of RTK action, and exert quantitative/qualitative signalling outcomes. The extent to which cells are competent to deal with fluc...
A variety of broadband wireless access technologies were investigated for improving the performance of GPS RTK systems. Compared with UHF radio modems, broadband wireless access technologies provide great advantages for RTK applications. For example, the line-of-sight condition for a radio link is not required any more except for “last mile” wireless connection (i.e., wireless connection of end...
BACKGROUND Signaling by receptor tyrosine kinase (RTK) pathways plays fundamental roles in processes of cell-fate determination, often through the induction of specific transcriptional responses. Yet it is not fully understood how continuous target gene expression, required for irreversible cell-fate specification, is preserved after RTK signaling has ended. Here we address this question using ...
Utilizing degenerate PCR primers complementary to conserved regions within the kinase domain of Receptor Tyrosine Kinase (RTK) genes, the goal was to compare the full complement of RTK expressed (mRNA level) between two developmental stages of bursal B-cells. We identified 21 different RTK cDNAs out of a total of 235 cDNAs sequenced between the two B-cell stages. The dataset revealed the expres...
Glioblastoma (GBM) is distinguished by a high degree of intratumoral heterogeneity, which extends to the pattern of expression and amplification of receptor tyrosine kinases (RTKs). Although most GBMs harbor RTK amplifications, clinical trials of small-molecule inhibitors targeting individual RTKs have been disappointing to date. Activation of multiple RTKs within individual GBMs provides a the...
Receptor tyrosine kinase (RTK) signaling pathways control multiple cellular decisions in metazoans, often by regulating the expression of downstream genes. In Drosophila melanogaster and other systems, E-twenty-six (ETS) transcription factors are considered to be the predominant nuclear effectors of RTK pathways. Here, we highlight recent progress in identifying the HMG-box protein Capicua (CIC...
