Characterizations of kites as graceful graphs

Cubo
We introduce and study an infinite family of graceful graphs, which we call kites. The kites are graphs where a path is joined with a graph "forming" a kite.

Increased Disarray of Extracellular Matrix Collagen‐I Fiber Network and Compromised Biomechanics in Aortae From Marfan‐Syndrome Mice Assessed Through Combined Opto‐Biomechatronics

Advanced Science, EarlyView.
Combined structure‐function assessment in aortic rings from Marfan mice using MechaMorph Opto‐Biomechatronics technology relates increased elasticity (stiffness) and dynamic viscosity and less ordered extracellular matrix 3D‐structure (collagen) as potential causes for impaired Windkessel function and compromised haemodynamics in Marfan's syndrome ...

Symmetric cryptography approach based on odd graceful labeling

Scientific African
In 1967, Rosa proposed the concept of graph labeling of a graph and the concept of the odd graceful labeling was introduced by Gnanajothi in 1991 as follows: Consider a graph G with q edges to be odd-graceful if there is an injection f from V ( G ) t o {

Decomposition of Certain Complete Graphs and Complete Multipartite Graphs into Almost-bipartite Graphs and Bipartite Graphs

Theory and Applications of Graphs, 2020
In his classical paper [14], Rosa introduced a hierarchical series of labelings called ρ, σ, β and α labeling as a tool to settle Ringel’s Conjecture which states that if T is any tree with m edges then the complete graph K2m+1 can be decomposed into 2m +

Transient Sleep Deprivation Induces Persistent Auditory Neuropathy via ROS‐Initiated Neuroinflammation and BK Channel Suppression

Advanced Science, EarlyView.
Sleep disturbance severity closely tracks hearing loss in a clinical cohort, yet the mechanistic link remains unclear. Acute sleep deprivation is shown to trigger transient cochlear oxidative stress that switches into a self‐sustaining neuroinflammatory state, suppressing BK channels and causing irreversible synaptopathy.

Edge Odd Graceful Labeling of Cylinder and Torus Grid Graphs

IEEE Access, 2019
Solairaju and Chithra introduced a new type of labeling of a graph G with p vertices and q edges called an edge odd graceful labeling if there is a bijection f from the edges of the graph to the set {1, 3, ...

ERα–PADI4–CXCL8 Axis Drives MDSC‐Mediated Immune Evasion in Anaplastic Thyroid Carcinoma

Advanced Science, EarlyView.
MAPK‐driven ligand‐independent ERα activation drives PADI4 transcription and translation. This enzyme then modifies CXCL8 chemokines through citrullination, generating a potent chemoattractant gradient specifically for myeloid‐derived suppressor cells.

On graceful colorings of trees [PDF]

Mathematica Bohemica, 2017
A proper coloring $c V(G)\to\{1, 2,\ldots, k\}$, $k\ge2$ of a graph $G$ is called a graceful $k$-coloring if the induced edge coloring $c' E(G) \to\{1, 2, \ldots, k-1\}$ defined by $c'(uv)=|c(u)-c(v)|$ for each edge $uv$ of $G$ is also proper.

MPP8 Facilitates DNA DSB Repair via NHEJ to Promote Chemoresistance of TNBC Independent of Methyl‐H3K9 Binding

Advanced Science, EarlyView.
Chemoresistance is often linked to elevated DNA repair. MPP8 is found to promote breast cancer chemoresistance as a novel NHEJ accessory factor independent of its epigenetic functions. Through multiple protein interactions, MPP8 facilitates association of DNAPK and ligase complexes to promote DNA repair progression.
