An example of a modeled relationship, in this case between Romeo (solid lines) and Juliet (dashed lines). The tau (τ) above the individual figures indicates the delay in reactivity. Delays that are too short (2,364). Delays in the range of 0,83-2,364 cause stability in Romeo and Juliet’s relationship. (Credit: Image courtesy of Radboud University Nijmegen)
TechAndComputer (Nov. 15, 2012) Neuroinformaticians from Radboud University Nijmegen provide a mathematical model for efficient communication in relationships. Love affair dynamics can look like a sinus wave: a smooth repetitive oscillation of highs and lows. For some couples these waves grow out of control, leading to breakup, while for others...

In financial ecosystems, big banks trample economic habitats and spread fiscal disease
- 14 November 2012
- Editor
Like the impact of an elephant herd grazing on grassland, multinational banks shape the financial environment to an extent that far outweighs their small number. And like a contagious person on a transnational flight, when these giant, interconnected banks succumb to financial ills, they are uniquely positioned to infect wide swaths of the financial system.

The aftermath of calculator use in college classrooms
- 12 November 2012
- Editor
TechAndComputer (Nov. 12, 2012) Math instructors promoting calculator usage in college classrooms may want to rethink their teaching strategies, says Samuel King, postdoctoral student in the University of Pittsburgh's Learning Research & Development Center. King has proposed the need for further research regarding calculators' role in the classroom after conducting a limited study with undergraduate engineering students published in the British Journal of Educational...
Species persistence or extinction: Through a mathematical lens
- 12 November 2012
- Editor
TechAndComputer (Nov. 12, 2012) Scientists have estimated that there are 1.7 million species of animals, plants and algae on earth, and new species continue to be discovered. Unfortunately, as new species are found, many are also disappearing, contributing to a net decrease in biodiversity. The more diversity there is in a population, the longer the ecosystem can sustain itself. Hence, biodiversity is key to ecosystem resilience.

New statistical method offers automatic mitotic cell detection for cancer diagnosis
- 12 November 2012
- Editor
TechAndComputer (Nov. 12, 2012) Scientists have developed a statistical image analysis method which can assist in the grading of breast cancer by automatically segmenting tumour regions and detecting dividing cells in tissue samples.
The system, developed at the University of Warwick, promises to bring objectivity and automation to the cancer grading process which is used to determine the aggressiveness of the treatment offered to the patient.

Origin of Italian wines is controlled better with multivariate statistics
- 07 November 2012

TechAndComputer (Nov. 7, 2012) Wine derives its economic value to a large extent from geographical origin, which has a significant impact on the quality of the wine. According to the food legislation, wines can be without geographical origin (table wine) and with origin. Wines with origin must have characteristics which are essentially due to its region of production and must be produced, processed and prepared exclusively within that region.

Common math standards supported with new study

TechAndComputer (Nov. 5, 2012) A new study analyzing the previous math standards of each state provides strong support for adoption of common standards, which U.S. students desperately need to keep pace with their counterparts around the globe, a Michigan State University scholar argues.
Forty-six states are implementing the Common Core math and reading standards, which nonetheless have come under fire recently by some researchers and would-be politicians.
