The use of modern didactic programs in mathematics in virtual reality (VR) requires approbation, proof of efficiency and environmental friendliness.VR properties: the ability to animate (perform actions with objects), interactivity and immersion in the information space are especially important for the training of future engineers, mathematicians a
Previous studies have discussed the impact of social context on language maintenance and shift of Chinese fangyan in metropolises, but not enough in rural areas.To explore the language maintenance and shift of the Hakka fangyan among Mid-mountain Hakka (MMH), a sub-branch of the Hakka people who live in Hakka-Chaoshan adjoining areas, this study ex

Abstract Background Hibernation allows animals to survive periods of resource scarcity by reducing their energy expenditure through decreased metabolism.However, hibernators become susceptible to psychrophilic pathogens if they cannot mount an efficient immune response to infection.While Nearctic bats infected with white-nose syndrome (WNS) suffer
Abstract We consider a large class of q-series that have the structure of Nahm sums, Feet Serum or equivalently motivic generating series for quivers.First, we initiate a systematic analysis and classification of classical and quantum A-polynomials associated to such q-series.These quantum quiver A-polynomials encode recursion relations satisfied b
