On the total vertex irregularity strength of comb product of two cycles and two stars
Indonesian Journal of Combinatorics, 2020 Let G = (V(G),E(G)) be a graph and k be a positive integer. A total k-labeling of G is a map f : V ∪ E → {1,2,3,...,k}. The vertex weight v under the labeling f is denoted by w_f(v) and defined by w_f(v) = f(v) + \sum_{uv \in{E(G)}} {f(uv)}.

Total Face Irregularity Strength of Grid and Wheel Graph under K-Labeling of Type (1, 1, 0)
Journal of Mathematics, 2021 In this study, we used grids and wheel graphs G=V,E,F, which are simple, finite, plane, and undirected graphs with V as the vertex set, E as the edge set, and F as the face set.

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications
FEBS Open Bio, EarlyView.This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.

Acoustic Measures Capture Speech Dysfunction in Spinocerebellar Ataxia
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Spinocerebellar ataxias (SCA) are hereditary cerebellar degenerative disorders with a common feature of dysarthria, involving impaired phonatory and articulatory control of speech, thereby affecting social communication. In this study, we investigated whether acoustic measures could objectively measure speech dysfunction and identify

On -irregularity strength of ladders and fan graphs
AKCE International Journal of Graphs and Combinatorics, 2020 We investigate modifications of the well-known irregularity strength of graphs, namely, total (vertex, edge) -irregularity strengths. Recently the bounds and precise values for some families of graphs concerning these parameters have been determined.

Age‐Related Characteristics of SYT1‐Associated Neurodevelopmental Disorder
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objectives We describe the clinical manifestations and developmental abilities of individuals with SYT1‐associated neurodevelopmental disorder (Baker‐Gordon syndrome) from infancy to adulthood. We further describe the neuroradiological and electrophysiological characteristics of the condition at different ages, and explore the associations ...

Irregularity Strength of Circulant Graphs Using Algorithmic Approach
IEEE Access, 2021 This paper deals with decomposition of complete graphs on $n$ vertices into circulant graphs with reduced degree $r< n-1$ . They are denoted as $C_{n}(a_{1}, a_{2}, {\dots }, a_{m})$ , where $a_{1}$ to $a_{m}$ are generators.

Variably Protease‐Sensitive Prionopathy: Two New Cases With Motor Neuron‐Dementia Syndrome
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT We describe two patients with variably protease‐sensitive prionopathy (VPSPr) who developed progressive upper motor neuron symptoms, insomnia, behavioral and cognitive decline, compatible with primary lateral sclerosis associated with frontotemporal dementia (FTD).

On total edge irregularity strength of polar grid graph
Journal of Taibah University for Science, 2019 For a graph $G $, an edge irregular total $r $-labelling $\pi :V \cup E \to \{{1,2,3, \ldots ,r} \} $ is a labelling for edges and vertices of a graph $G $ in such a way that the weights of any two different edges are distinct. The minimum for which $G $

Developmental and Epileptic Encephalopathy due to Biallelic Pathogenic Variants in PIGM
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective PIGM encodes a critical enzyme in the glycosylphosphatidylinositol (GPI)‐anchor biosynthesis pathway. While promoter‐region mutations in PIGM have been associated with a relatively mild phenotype characterized by portal vein thrombosis and absence seizures, recent evidence suggests that coding‐region mutations result in a more severe
