Multiple functions of protein phosphatases in receptor tyrosine kinase signaling revealed by interactome analysis

open access: yesMolecular & Cellular Oncology, 2017
To obtain a global picture of how protein phosphatases are involved in receptor tyrosine kinase (RTK) signaling, we mapped the RTK-phosphatase interactome. Analyses of selected interactions revealed detailed mechanisms of their actions.

An In-Vehicle Smartphone RTK/DR Positioning Method Combined with OSM Road Network

open access: yesRemote Sensing, 2023
In vehicle navigation scenarios, the RTK positioning results of smartphones are prone to jumps due to the interference of complex urban environments, and the heading angle of dead reckoning (DR) is prone to divergence.

Examining the Accuracy of Network RTK and Long Base RTK Methods with Repetitive Measurements [PDF]

open access: yesJournal of Sensors, 2019
Real-time kinematic (RTK) technique is important for mapping applications requiring short measure time, the distance between rover and base station, and high accuracy. There are several RTK methods used today such as the traditional RTK, long base RTK (LBRTK), network RTK (NRTK), and precise point positioning RTK (PPP-RTK).

On the accuracy of low-cost dual-frequency GNSS network receivers and reference data

open access: yesGIScience & Remote Sensing, 2020
The trend in spatial data accuracy has gone from meters to decimeters and even centimeter levels in the last two decades. In large part, the centimeter(s) level spatial accuracies of geospatial products result from the use of LiDAR data and both low ...
