Wireless Sensor Networks for Ecology

linked profile(s): Hans
submitted by: apryl
AbstractField biologists and ecologists are starting to open new avenues of inquiry at greater spatial and temporal resolution, allowing them to “observe the unobservable” through the use of wireless sensor networks. Sensor networks facilitate the collection of diverse types of data (from temperature to imagery and sound) at frequent intervals—even multiple times per second—over large areas, allowing ecologists and field biologists to engage in intensive and expansive sampling and to...

Tumour cords' growth in a vascular network

submitted by: sast
Evolutions of oxygen concentration and formation of hypoxic zones during tumour growth in the vascular network . This simulation was produced with an experimental modification to the model, where vessels are oxygen sources inside the simulation domain, cells do not switch to anaerobic metabolism in this simulation.

ATP deficit in oxygen-limited tumour cord growth (FF++)

submitted by: sast
This is a simulation of tumour cord growth , where cells suffer from hypoxia (energy deficit shown with colour). The tumour grows along the blood vessel (coincides with x -axis). Red line shows the position of the tumour–host interface. This particular simulation was programmed in FreeFEM++ out of curiousity. The source code for simulation may be found at . This video reflects work in progress and may be different from the final results .
