Mathematical monotsukuri: Summing a constant may help to detect synchronized brain activityScientists at Tokyo Institute of Technology found a simple, yet effective way to improve how synchronization is measured in chaotic systems. The technique consists of adding a constant parameter to the "analytic signals" in a way that emphasizes certain aspects of their timing. This could improve brain-computer interfaces designed to aid disabled people.

Mathematics Thu, 14 Feb 2019 07:21:33 ESTnews469351285Mathematicians report a way to optimize post-stroke therapyRUDN 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.

The study provides a method to analyze such systems and find out the most optimal decision by means of calculations. The work was published in Information Sciences.

Mathematics Wed, 13 Feb 2019 07:11:13 ESTnews469264264Improving geothermal HVAC systems with mathematicsExtreme weather events, water shortages, and other consequences of climate change have challenged—and compromised—energy infrastructure around the world. Increased energy consumption is threatening the longevity of a dependable energy supply, and significant reductions to collective energy usage are necessary to mitigate the continued effects of a warming climate. Most energy sources require fuel and emit greenhouse gases and other forms of air pollution. For example, the heating and cooling of buildings accounts for over 25 percent of the world's energy consumption. In the European Union specifically, buildings are responsible for approximately 40 percent of energy consumption and 36 percent of carbon dioxide emission. Because nearly three-quarters of its buildings are considered energy inefficient, the EU recently updated its Energy Performance of Buildings Directive to require that all newly-constructed buildings be nearly zero-energy by 2021.

Even though the sandpile model serves as the archetypal model to study self-organized criticality, questions about its characteristics are still open and remain an active field of research.

This procedure is used to treat stroke patients. To do so, the scientists generally formulated the task by creating a reaction-diffusion equation and carried out a theoretical study of it. The results of the study were published in Applied Mathematics Letters.

Frogs communicate with sound, and amid their ruckus is an internally orchestrated system that lets information get through more clearly while also permitting collective choruses and time to rest. Researchers from Osaka University and University of Tsukuba sought to leverage this amphibious acumen for mathematical and technological aims.

Big cities also allow burglars to maintain anonymity and evade authority while offering ample opportunities for discreet disposal of stolen property. Burglars observe their target cities with the careful attention of urban planners, taking note of public spaces, roadways, building architecture, behavior patterns, and tenant schedules. Although law enforcement is making concerted efforts to address and prevent burglary, frequent offenses in major metropolises continue to unsettle city-dwellers.
