'Memristors' based on transparent electronics offer technology of the future

  • PDF
TechAndComputer (Sep. 14, 2012) — The transparent electronics that were pioneered at Oregon State University may find one of their newest applications as a next-generation replacement for some uses of non-volatile flash memory, a multi-billion dollar technology nearing its limit of small size and information storage capacity.

Researchers at OSU have confirmed that zinc tin oxide, an inexpensive and environmentally benign compound, has significant potential for use in this field, and could provide a new, transparent technology where computer memory is based on resistance, instead of an electron charge.

The findings were recently published in Solid-State Electronics, a professional journal.

A Travelling Salesman Problem special case: 30-year-old problem solved

  • PDF
TechAndComputer (Sep. 13, 2012) — The science of computational complexity aims to solve the TSP -- the Travelling Salesman Problem -- when the time required to find an optimal solution is vital for practical solutions to modern-day problems such as air traffic control and delivery of fresh food. Warwick Business School's Dr Vladimir Deineko and colleagues have now solved a 30-year-old TSP special case problem. Share This: See Also: Computers & MathComputer...

Mathematical model may lead to safer chemotherapy

  • PDF
TechAndComputer (Sep. 12, 2012) — Cancer chemotherapy can be a life-saver, but it is fraught with severe side effects, among them an increased risk of infection. Until now, the major criterion for assessing this risk has been the blood cell count: if the number of white blood cells falls below a critical threshold, the risk of infection is thought to be high.

Computer program deals with patients who fail to keep appointments

  • PDF
TechAndComputer (Sep. 10, 2012) — A problem faced by patients seeking medical attention is often getting a clinic appointment at a time convenient to them. Conversely, cancellations and more crucially "no-shows" by patients can disrupt the day-to-day scheduling of a medical practice leading to frustration for patients and staff alike as well as affecting efficiency in a negative manner and leading to lost revenue.
