Thank you for considering MindModeling! We appreciate any and all support.
Our project has supported several scientists and engineers in their research over the years. The key issue is that those who develop and run the MM system (currently Olivia and I) are not the ones publishing the work or writing the models.
We ask that the S&Es notify us of their publications that utilize MM, but this hasn't been updated the last several years (as you noticed). That doesn't mean the work units are useless, just that we've done a bad job at collecting and publishing that info!
For example, the currently running model (only on Linux/Lisp) is looking at a model of fatigue and it's effects on cognitive performance. This will help answer questions like: when do we need to schedule crew rest to maintain a safe level of performance?
The maintenance I've discussed before is to the server-side infrastructure and web application that allows those S&E's to submit their jobs to BOINC. We've had several issues lately that need addressed. That doesn't mean the work is of less quality or worth! Far from it.
I hope this answers your questions. Thank you for your time!
