Optimal horse racing speed over the course of a flat race pinpointed by mathematical analysis to help achieve the fastest time, including adjustments for racecourse topography
Light-induced processes are critical in transformative technologies such as solar energy harvesting, as well as in photomedicine and photoresponsive materials. Theoretical studies of the dynamics of photoinduced processes require numerous electronic structure calculations, which are computationally expensive. Scientists from the University of Groningen developed machine learning-based algorithms, which reduce these computations significantly. The Open Source software package that they developed, PySurf, was presented in a paper in the Journal of Chemical Theory and Computation.
Is there a unifying principle underpinning animal locomotion in its rich diversity? The thermodynamic analysis shows why and how waste minimization prevails on efficiency or power maximization when it comes to free locomotion irrespective of the available mode and gaits.
Engineering a spaceship is as difficult as it sounds. Modeling plays a large role in the time and effort it takes to create spaceships and other complex engineering systems. It requires extensive physics calculations, sifting through a multitude of different models and tribal knowledge to determine singular parts of a system's design.
Use of an algorithm for computing viral mutations homogeneously across sources, using cloud computing.
Researchers from Skoltech and their colleagues from Germany and the US have studied the properties and behavior of a palladium-copper alloy under changing temperatures and hydrogen concentrations, with highly relevant implications of this research for catalyst design. The authors hope that their findings can open the door for designing metal alloys with better catalytic properties by taking into account dynamic changes in the composition and structure of materials at realistic operational conditions.
Findings will help wildlife managers track and predict the dynamics of large carnivore populations.
A systematic search for copies of the first edition of Newton's Principia (1687) unearthed copies in at least 27 countries, yielding new insights about how people engaged with the famous book.
Scientists from Skoltech puzzled out the physical meaning of the mysterious Mendeleev Numbers and suggested calculating them based on the fundamental properties of atoms. They showed that both MNs and the chemical space built around them were more effective than empirical solutions proposed until then.
The study merges demographic data, epidemiological estimates and anonymous cellphone location information, and appears to confirm that most COVID-19 transmissions occur at "superspreader" sites like full-service restaurants, fitness centers and cafes, where people remain in close quarters for extended periods. The model could help officials minimize the contagion as they reopen businesses by revealing the tradeoffs between infections and sales if establishments open at 20 percent or 50 percent or full capacity.
