The High Performance Wireless Research and Education Network (HPWREN)

submitted by: Hans

The High Performance Wireless Research and Education Network (HPWREN) is a National Science Foundation funded network research project, which also functions as a collaborative interdisciplinary and multi-institutional cyberinfrastructure for research, education, and first responder activities. The program includes the creation, demonstration, and evaluation of a non-commercial, prototype, high-performance, wide-area, wireless network in San Diego, Riverside, and Imperial counties.

Methylphenidate Decreased the Amount of Glucose Needed by the Brain to Perform a Cognitive Task

submitted by: noravolkow
The use of stimulants (methylphenidate and amphetamine) as cognitive enhancers by the general public is increasing and is controversial. It is still unclear how they work or why they improve performance in some individuals but impair it in others. To test the hypothesis that stimulants enhance signal to noise ratio of neuronal activity and thereby reduce cerebral activity by increasing efficiency, we measured the effects of methylphenidate on brain glucose utilization in healthy adults. We...

Saving the Tijuana Estuary

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.
