A New Way to Evaluate Lobachevsky’s Integrals

open access: yesInternational Journal of Mathematics and Mathematical Sciences
This article examines the family of Lobachevsky’s integrals and presents an alternative derivation for the four convergent cases. The approach relies on Leibniz’s parameter differentiation technique, partial fraction decomposition, and expansions in power series.

Toward Interactions through Information in a Multifractal Paradigm

open access: yesEntropy, 2020
In a multifractal paradigm of motion, Shannon’s information functionality of a minimization principle induces multifractal–type Newtonian behaviors. The analysis of these behaviors through motion geodesics shows the fact that the center of the Newtonian ...

Royal jelly plus coenzyme Q10 supplementation improves high-intensity interval exercise performance via changes in plasmatic and salivary biomarkers of oxidative stress and muscle damage in swimmers: a randomized, double-blind, placebo-controlled pilot trial

open access: yesJournal of the International Society of Sports Nutrition, 2022
Background Excessive production of free radicals caused by many types of exercise results in oxidative stress, which leads to muscle damage, fatigue, and impaired performance.

Hyperbolic geometry "lupis": Hypothetical learning trajectory of the triangle in the context of Sumatra [PDF]

open access: yesEuropean Journal of STEM Education
Lobachevsky geometry is an elective course that is difficult for students to learn. One of them is the concept of the number of angles in a triangle less than 180 degrees. The purpose of this study is to produce a design of a Triangle learning trajectory

Obtaining nickel nanoparticles by the gas-phase method - induction flow levitation [PDF]

open access: yesE3S Web of Conferences, 2023
In this paper, we consider the possibility of obtaining nickel nanoparticles from a bulk sample by the method of induction flow levitation. This method is based on non-contact heating and holding a metal sample in a state of levitation by a high ...

The Combination of Two Small Molecules Improves Neurological Parameters and Extends the Lifespan of C3H Strain Female Mice. [PDF]

open access: yesBrain Behav
The small molecules RepSox and TCP were investigated for their geroprotective effects in aging C3H mice through intraperitoneal administration. Treatment resulted in improved neurological markers and physical parameters in older mice (16‐20 months), while younger treated mice (10‐13 months) showed increased maximum lifespan compared to controls.

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 ...
