Did Lobachevsky Have A Model Of His "imaginary Geometry"? [PDF]
Journal of Physics: Conference Series, 2010 The invention of non-Euclidean geometries is often seen through the optics of Hilbertian formal axiomatic method developed later in the 19th century. However such an anachronistic approach fails to provide a sound reading of Lobachevsky's geometrical works.

On the possibility of teaching elements of Lobachevski Geometry at School [PDF]
, 2012 It is useful to teach elements of Lobachevsky geometry at school because the study of non-Euclidean geometry makes good impact on the understanding of logical structure of school geometry, on the comprehension of the role and place of the axiom of parallelism. We propose and describe here the program of such course.

Rectangles in Lobachevsky Geometry [PDF]
Interactive science, 2020 If we replace the V Postulate of Euclid with the Postulate of Lobachevsky, then we can get rectangles with more than 4 angles. The article describes the methodology for constructing such rectangles.

Variability in Resistive Memories
Advanced Intelligent Systems, Volume 5, Issue 6, June 2023., 2023 A comprehensive review of variability in resistive memories is presented. Experimental evidence of variability for resistive memories is described. Later on, different approaches to model this variability from the physical, behavioral, and stochastic viewpoints are presented.

A relative version of the Turaev–Viro invariants and the volume of hyperbolic polyhedral 3‐manifolds
Journal of Topology, Volume 16, Issue 2, Page 650-678, June 2023., 2023 Abstract We define a relative version of the Turaev–Viro invariants for an ideally triangulated compact 3‐manifold with nonempty boundary and a coloring on the edges, generalizing the Turaev–Viro invariants [36] of the manifold. We also propose the volume conjecture for these invariants whose asymptotic behavior is related to the volume of the manifold

Observation of Robust Polarization Squeezing via the Kerr Nonlinearity in an Optical Fiber
Advanced Quantum Technologies, Volume 6, Issue 3, March 2023., 2023 Squeezed light is a photonic quantum technology resource. The optical Kerr effect is often used to generate polarization squeezing. Such setups have been very sensitive to fluctuations of external factors. Here, a new all‐fiber very stable passive setup generating more than 5 dB of squeezing is presented.

Philosophy Compass, Volume 17, Issue 4, April 2022., 2022 Abstract How is it that the basic structures of space and time come to manifest themselves in physical theories and theorising, and in our empirical experience of the world? This question is central to an important field of the philosophy of physics: the epistemology of spacetime.

Data analysis on nonstandard spaces
WIREs Computational Statistics, Volume 13, Issue 3, May/June 2021., 2021 Surveying many non‐Euclidean statistical problems with ingenious solutions, we uncover new ones, keeping mathematicians, statisticians, computer and data scientists busy for a while. Abstract The task to write on data analysis on nonstandard spaces is quite substantial, with a huge body of literature to cover, from parametric to nonparametrics, from ...

International Journal of Quantum Chemistry, Volume 121, Issue 2, January 15, 2021., 2021 The comparison of 27 bare TiO2 and TiO2/organic clusters calculated at the DFTB level with results of B3LYP calculations shows that DFTB parameter sets (tiorg‐smooth, trans3d, and matsci) describe the structure and properties of clusters (HOMO‐LUMO gap, potential ionization, and electron transfer characteristics) at a level that is close to DFT ...
