Rosamund Sutherland obituary

My friend and colleague Rosamund Sutherland, who has died aged 72, was an internationally acclaimed professor of mathematics education. She was a pioneer in demonstrating how students’ learning in school can surpass expectations with the support of expert teachers and digital technology. She piloted new ways in which institutions can, through cooperation, begin to overcome…

Simon Norton obituary

Simon Norton, who has died of a heart attack aged 66, was a world-class mathematician sometimes mistaken for a homeless man. In the late 1960s he represented Britain at the International Mathematical Olympiads three times, scoring the top grade each time, once with 100%, another time with 99%, and winning a special prize for the…

Epidemiological model lends insight to chlamydia outbreak in Japan

Mathematical models that quantify the dynamics of infectious diseases are crucial predictive tools for the control of ongoing and future outbreaks. An infection’s basic reproduction number (R0) is especially important to disease modeling and epidemiology,…

Mathematicians report a way to optimize post-stroke therapy

Credit: Natalia Deryugina/VSRao RUDN scientists have created a mathematical model describing changes in the properties of brain tissues after stroke. The development will help clinicians to optimize post-stroke therapy by stimulating brain neurons and taking into account each patient’s individual situation. The results of the study were published in Mathematical Biosciences. Over 15 million people…

Improving geothermal HVAC systems with mathematics
