GPS technology, in particular real-time kinematic (RTK) GPS, has matured to the stage where it has become another tool for the professional surveyor. Commercial products offer user-friendly hardware/software and suggest techniques that can improve productivity at a high accuracy. Government services such as SCIMS in NSW and AUSPOS (Geoscience Australia) support improved GPS positioning and surv...
Activation of receptor tyrosine kinases (RTKs) by secreted growth factors regulates cell proliferation and cell fate determination in many different cellular and developmental contexts. Despite such widespread functions, RTK signalling involves a common cytoplasmic cascade including Ras, and the serine-threonine kinases Raf, MAPKK/MEK and MAPK. Thus, a central issue is how activation of the sam...
There are three quantitative phosphoproteomic strategies most commonly used to study receptor tyrosine kinase (RTK) signaling. These strategies quantify changes in: (1) all three forms of phosphosites (phosphoserine, phosphothreonine and phosphotyrosine) following enrichment of phosphopeptides by titanium dioxide or immobilized metal affinity chromatography; (2) phosphotyrosine sites following ...
We investigated the potential use of real-time kinematic (RTK) global positioning system (GPS) to determine seedling distribution and plant growing area mapping by evaluating the obtained level of accuracy. High-accuracy seed and plant growing area mapping can potentially be used in the evaluations of seeding machine performance, weed control, and plant-specific crop management. Actual plant lo...
Growth factor receptor tyrosine kinase (RTK) pathway activation is a key mechanism for mediating cancer growth, survival, and treatment resistance. Cognate ligands play crucial roles in autocrine or paracrine stimulation of these RTK pathways. Here, we show SEMA3C drives activation of multiple RTKs including EGFR, ErbB2, and MET in a cognate ligand-independent manner via Plexin B1. SEMA3C expre...
This paper reviews the establishment of GPS continuously operating reference stations (CORS) by government agencies and research institutes over the last two decades. The justification for the establishment of CORS networks was initially in support of geodesy and other geoscientific applications, at the global and regional level. However, increasingly GPS CORS network operators have sought ways...
