Generation and study of the synthetic brain electron microscopy dataset for segmentation purpose

open access: yesКомпьютерная оптика, 2023
Advanced microscopy technologies such as electron microscopy have opened up a new field of vision for biomedical researchers. The use of artificial intelligence methods for processing EM data is largely difficult due to the small amount of annotated data

Quantum Lobachevsky planes [PDF]

open access: yesJournal of Mathematical Physics, 1996
We classify all SL(2,R)-covariant Poisson structures on the Lobachevsky plane with respect to all multiplicative Poisson structures on SL(2,R) and describe quantizations for all these Poisson structures.

Barbier's Theorem in the Lobachevski Plane [PDF]

open access: yesProceedings of the American Mathematical Society, 1970
In the Lobachevski plane, horocycles with the same center are geodesic parallels and are natural replacements for the lines used in defining the support function of a convex curve and the notion of constant width in the Euclidean plane. In this paper, analogs based on horocycles are obtained for Christoffel’s formula, which expresses the radius of ...

Fractal Information by Means of Harmonic Mappings and Some Physical Implications

open access: yesEntropy, 2016
Considering that the motions of the complex system structural units take place on continuous, but non-differentiable curves, in the frame of the extended scale relativity model (in its Schrödinger-type variant), it is proven that the imaginary part of a ...
