Observability in problems of mathematical physics
Izvestiya MGTU MAMI, 2012 Attention is drawn to the importance of the observation principle in the physical Sciences, which means that hypothesis and theory should be formulated in terms of observable nature values. Experiment and practice, not the opinions of authorities, are criteria of truth. Forgetting this leads to big, but ineffectual material expenses.

Advanced Healthcare Materials, EarlyView.This study developed a bioprinted co‐culture system embedding rat pancreatic islets and Scenedesmus sp. microalgae spatially defined in close vicinity. Red light was found optimal to ensure microalgal photosynthesis while maintaining islet viability and functionality. A tailored co‐culture medium supported both cell types.

Nonlocal Conduction in a Metawire
Advanced Materials, Volume 37, Issue 13, April 2, 2025.A 1D metawire composed of twisted copper wires is designed and realized. This metamaterial exhibits pronounced effects of nonlocal electric conduction according to Ohm's law. The current at one location not only depends on the electric field at that location but also on other locations.

Cross-constrained problems for nonlinear Schrodinger equation with harmonic potential
Electronic Journal of Differential Equations, 2012 This article studies a nonlinear Schodinger equation with harmonic potential by constructing different cross-constrained problems. By comparing the different cross-constrained problems, we derive different sharp criterion and different invariant ...

Advanced Materials, EarlyView.Highly water‐soluble dicationic bis(indolium) dyes have been prepared, showing excellent two‐photon absorption and light emission. Their fluorescence behavior discloses an unusual increasing blue shift with increasing solvent polarity, which, in parallel, is beneficial for enhanced detection in biological media.
