Abstract Thanks to the development of real-time kinematic (RTK) algorithm and emerging Global Navigation Satellite System (GNSS), especially for Galileo BeiDou-3, reliable positioning accuracy medium long-baseline RTK became possible globally. Moreover, with GNSS receiver hardware, baseline length limitations due radio-based communications are removed thanks internet-based communication. In thi...

High-precision global navigation satellite system (GNSS) is a crucial geolocalization feature enabling wide range of applications, from mobile Internet-of-Things devices to autonomous drones and self-driving vehicles. Real-time kinematic (RTK) GNSS technology that attracting increased interest due the centimeter precision achievable when wireless communication present on devices. On other hand,...

Topografyanın engebeli ve ulaşılması zor olduğu alanlarda yersel ölçüm teknikleri ile yapmadaki güçlükler nedeniyle uzaktan algılama kullanımını bu tür durumlarda vazgeçilmez kılmaktadır. Gerçek zamanlı kinematik (Real Time Kinematic-RTK) tekniği konumsal verilerin doğruluğunda santimetre hassasiyetinde çalışmalar ortaya konulabilmektedir. Ancak topoğrafik yapısı, uydu bazlı konumlamaya uygun o...

As the modern navigation business evolves, demands for high-precision positioning in GNSS-challenged environments increase, and integrated system composed of Global Navigation Satellite System (GNSS)-based Real-Time Kinematic (RTK), inertial (INS), Light Detection Ranging (LiDAR), etc., is accepted as most feasible solution to issue. For prior-map-free situations, only sensor with a global fram...

The Listeria monocytogenes surface protein InlB promotes bacterial entry into mammalian cells. Here, we identify a cellular surface receptor required for InlB-mediated entry. Treatment of mammalian cells with InlB protein or infection with L. monocytogenes induces rapid tyrosine phosphorylation of Met, a receptor tyrosine kinase (RTK) for which the only known ligand is Hepatocyte Growth Factor ...

15 Several golf greens were mapped using a RTK GPS, Riegl 3D-Laser Mirror Scanner and Trimble S6 Robotic Total Station systems to determine the most appropriate method for this task. The RTK GPS was the easiest methods for data capture but was insufficiently accurate for 20 mapping at a contour interval of 0.05 m or less in this situation. The laser scanner level data accuracy was slightly more...

During development and tissue homeostasis, cells must integrate different signals. We investigated how cell behavior is controlled by the combined activity of transforming growth factor-beta (TGF-beta) and receptor tyrosine kinase (RTK) signaling, whose integration mechanism is unknown. We find that RTK/Ras/MAPK (mitogen-activated protein kinase) activity induces p53 N-terminal phosphorylation,...

Most growth factors control cellular functions by activating specific receptor tyrosine kinases (RTKs). While overactivation of RTK signalling pathways is strongly associated with carcinogenesis, it is becoming increasingly clear that impaired deactivation of RTKs may also be a mechanism in cancer. A major deactivation pathway, receptor downregulation, involves ligand-induced endocytosis of the...

The integration of global navigation satellite system (GNSS) single-frequency (SF) real-time kinematics (RTKs) and inertial (INS) has the advantages low-cost low-power consumption compared to multiple-frequency GNSS RTK/INS system. However, due vulnerability signal reception, application SF-RTK/INS is limited in complex environments. To improve positioning accuracy GNSS-blocked environments, we...
