Nine Digits

Nine Digits

Arrange the given digits one to nine to make three numbers such that two of them add up to the third. This is a great puzzle for practicing standard pen and paper methods of three digit number addition and subtraction.

Mathematical modeling vital to tackling disease outbreaks

Predicting and controlling disease outbreaks would be easier and more reliable with the wider application of mathematical modelling, according to a new study. more...

Information theory as a forensics tool for investigating climate mysteries

During Earth's last glacial period, temperatures on the planet periodically spiked dramatically and rapidly. A new article suggests that mathematics from information theory could offer a powerful tool for analyzing and understanding these mysterious events. more...

Experiment measures velocity in 3D

Many of today's scientific processes are simulated using computer-driven mathematical models. But for a model to accurately predict how air flow behaves at high speeds, for example, scientists need supplemental real life data. Providing validation data, using up-to-date methods, was a key motivating factor for a recent experimental study. more...

Algorithm personalizes which cancer mutations are best targets for immunotherapy

As tumor cells multiply, they often spawn tens of thousands of genetic mutations. Figuring out which ones are the most promising to target with immunotherapy is like finding a few needles in a haystack. Now a new model hand-picks those needles so they can be leveraged in more effective, customized cancer vaccines. more...

Revamped crew scheduling model cuts airline delays by as much as 30%

Delays and disruptions in airline operations annually result in billions of dollars of additional costs to airlines, passengers and the economy. Airlines strive to mitigate these costs by creating schedules that are less likely to get disrupted or schedules that are easy to repair when there are disruptions -- new research has found a solution using a mathematical optimization model. more...

Computer kidney sheds light on proper hydration

A new computer kidney could tell researchers more about the impacts of medicines taken by people who don't drink enough water. more...

Curved nanochannels allow independent tuning of charge and spin currents

To increase the efficiency of microchips, 3D structures are now being investigated. However, spintronic components, which rely on electron spin rather than charge, are always flat. To investigate how to connect these to 3D electronics, physicists have created curved spin transport channels. They discovered that this new geometry makes it possible to independently tune charge and spin currents. more...
