From curves to currents

open access: yesForum of Mathematics, Sigma, 2021
Many natural real-valued functions of closed curves are known to extend continuously to the larger space of geodesic currents. For instance, the extension of length with respect to a fixed hyperbolic metric was a motivating example for the development of

Extremal Binary and Ternary Codes of Length 60 with an Automorphism of Order 29 and a Generalization

open access: yesMathematics, 2022
In this paper, all extremal Type I and Type III codes of length 60 with an automorphism of order 29 are classified up to equivalence. In both cases, it has been proven that there are three inequivalent codes.

Extremal Digraphs Avoiding Distinct Walks of Length 4 with the Same Endpoints

open access: yesDiscussiones Mathematicae Graph Theory, 2022
Let n ≥ 8 be an integer. We characterize the extremal digraphs of order n with the maximum number of arcs avoiding distinct walks of length 4 with the same endpoints.

The maximum number of $P_\ell$ copies in $P_k$-free graphs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2019
Generalizing Tur\'an's classical extremal problem, Alon and Shikhelman investigated the problem of maximizing the number of $T$ copies in an $H$-free graph, for a pair of graphs $T$ and $H$.

The clinical spectrum of SMA‐PME and in vitro normalization of its cellular ceramide profile

open access: yesAnnals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1941-1952, December 2022., 2022
Abstract Objective The objectives of this study were to define the clinical and biochemical spectrum of spinal muscular atrophy with progressive myoclonic epilepsy (SMA‐PME) and to determine if aberrant cellular ceramide accumulation could be normalized by enzyme replacement.

On the first general Zagreb eccentricity index

open access: yesAIMS Mathematics, 2021
In a graph G, the distance between two vertices is the length of the shortest path between them. The maximum distance between a vertex to any other vertex is considered as the eccentricity of the vertex.

Selection of worm gearing optimal structure for machine rotary table

open access: yesDiagnostyka, 2021
In this paper, the design of the machine rotary table with a kinematic worm gearing is research. A three-dimensional model of the rotary table assembly structure and the stress-strain state of the worm by the finite element method are researched ...

On Eccentric Adjacency Index of Graphs and Trees [PDF]

open access: yesMathematics Interdisciplinary Research, 2023
Let $G=(V(G),E(G))$ be a simple and connected graph. The distance between any two vertices $x$ and $y$, denoted by $d_G(x,y)$, is defined as the length of a shortest path connecting $x$ and $y$ in $G$.The degree of a vertex $x$ in $G$, denoted by $\deg_G(
