A team of mathematicians from RUDN University found a way to reduce the size of a trained neural network six times without spending additional resources on re-training it. The approach is based on finding a correlation between the weights of neural connections in the initial system and its simplified version.
Individual characteristics of the shape and cross-section of the root canal are one of the main issues for dentists. When treating a root canal, a doctor needs to properly clean it, fill it, and carry out a rebuilding procedure so that a canal is sealed. The first stage of endodontic treatment requires detailed knowledge of root canal anatomy. A team of dentists from RUDN University studied and classified various changes in root canal shapes. The new classification will help doctors avoid diagnostic errors, better select their tools, and treat patients more efficiently.
An international team including chemists from RUDN University suggested an economically feasible and environmentally friendly method to synthesize surfactants. The new compounds can become an eco-friendly alternative to traditional chemicals used in oil production, skincare products manufacture, and in the pharmaceutical industry to transport drugs to diseased body tissues.
A professor from RUDN University together with his colleagues from Saratov Chernyshevsky State University and D. Mendeleev University of Chemical Technology of Russia developed a method for calculating the parameters of diffraction optical elements used in LCDs. In particular, the new technology can be used to expand the angle of view while preserving high resolution and color rendition.
A professor from RUDN University together with his Indian colleagues synthesized and studied new dibenzophenazine-based liquid crystals that could potentially be used in optoelectronics and solar panels.
A team of chemists from RUDN University created an antibacterial coating for food products. The mixture consists of two components that are safe for human health and form a thin, non-toxic, and biodegradable film. The film has no color or flavor and can increase the shelf life of different products 2.5 to 8 times.
February 15, RUDN University annual award in the field of science and innovation was presented. The highest award of the university was received by associate professor of the Faculty of Science Fyodor Zubkov and the team of authors of the Law Institute: Aslan Abashidze, Alexander Solntsev and Denis Gugunsky.
Mathematics, chemistry, physics, medicine and modern languages - there are five priority areas of development at RUDN University along the path of a research university. RUDN University has a developed laboratory base, it encourages publication activity, forms teams of scientists and educates talented young researchers.
Gravity might play a bigger role in the formation of elementary particles than scientists used to believe. A team of physicists from RUDN University obtained some solutions of semi-classical models that describe particle-like waves. They also calculated the ratio between the gravitational interaction of particles and the interaction of their charges.
Iron minerals and bacteria can be the main agents of carbon dioxide emissions from the soil. A soil scientist from RUDN University made this conclusion after studying the process of organic plant waste decomposition of the micro-level. Iron and hydrogen peroxide enter into a reaction, as a result of which active oxygen forms (oxygen radicals) are formed. The radicals destroy plant waste in the soil and promote carbon dioxide emissions.
A soil scientist from RUDN University studied the effect of forest conversion on the properties of the soil: its acidity, carbon and nitrogen resources, bacterial composition, and the activity of microorganisms. The study can help improve the methods of soil cultivation after deforestation, namely, select the best fertilizers, prevent erosion, slow down nutrient depletion, and balance the composition of the bacterial community.
Irina Chernykh and Konstantin Gomonov, PhDs, became winners of the competition for a Presidential grant for young scientists. Grants are awarded for two years for fundamental and applied research.
