Reduced clique graphs of chordal graphs [PDF]

European Journal of Combinatorics, 2012
AbstractWe investigate the properties of chordal graphs that follow from the well-known fact that chordal graphs admit tree representations. In particular, we study the structure of reduced clique graphs which are graphs that canonically capture all tree representations of chordal graphs.

Sono‐Controllable Janus Hydrogel Platform for Sequential Tumor Eradication and Bone Regeneration in Metastatic Breast Cancer

Advanced Science, EarlyView.
Sequential tumor eradication and bone regeneration remain a significant challenge for patients with breast cancer bone metastases. This study develops a novel Janus hydrogel platform, which can achieve tumor elimination and bone repair under the action of different ultrasound frequencies.

A new method for computing the vertex PI index with applications to special classes of graphs

AKCE International Journal of Graphs and Combinatorics
The Padmakar-Ivan (PI) index of a graph G is given by [Formula: see text], where [Formula: see text] is the number of equidistant vertices for the edge e.

Heroes in Orientations of Chordal Graphs

SIAM Journal on Discrete Mathematics, 2022
We characterize all digraphs $H$ such that orientations of chordal graphs with no induced copy of $H$ have bounded dichromatic number.

KLK1 as an Epithelial‐Specific Brake Inhibits Colorectal Tumorigenesis by Suppressing B1R‐Mediated Fibroblast Phenotypic Transition

Advanced Science, EarlyView.
KLK1 downregulation disrupts the intestinal mucosal barrier and impairs kallikrein‐kinin signaling, thereby reducing Lys‐des‐Arg9‐BK production. This enhances B1R activation on ADAMDEC1⁺ fibroblasts, promoting inflammation and extracellular matrix (ECM) remodeling. The resulting iCAFs promote colorectal cancer progression, highlighting a novel KLK1‐B1R

Targeting ROCK2 to Restore Epileptic Synaptic Networks via Mitophagy Activation: Insights from Translational Imaging of SV2A In Vivo

Advanced Science, EarlyView.
By integrating synaptic vesicle glycoprotein 2A PET imaging and transcriptomics, this study identifies Rho‐associated protein kinase 2 (ROCK2) as a critical regulator of synaptic network dysfunction in temporal lobe epilepsy. Pharmacological ROCK2 inhibition restores synaptic density and enhances mitophagy, thereby reducing seizures and neuronal damage.

The Topological Connectivity of the Independence Complex of Circular-Arc Graphs

Universal Journal of Mathematics and Applications, 2019
Let us denoted the topological connectivity of a simplicial complex $C$ plus 2 by $\eta(C)$. Let $\psi$ be a function from class of graphs to the set of positive integers together with $\infty$. Suppose $\psi$ satisfies the following properties: \newline

Multiscale Cell–Cell Interactive Spatial Transcriptomics Analysis

Advanced Science, EarlyView.
In this study, we present the MultiScale Cell‐Cell Interactive Spatial Transcriptomics Analysis method, which unites the strengths of spatially resolved deep learning techniques with a topological representation of multi‐scale cell‐cell similarity relations.

On a Class of Graphs with Large Total Domination Number [PDF]

Discrete Mathematics & Theoretical Computer Science, 2018
Let $\gamma(G)$ and $\gamma_t(G)$ denote the domination number and the total domination number, respectively, of a graph $G$ with no isolated vertices. It is well-known that $\gamma_t(G) \leq 2\gamma(G)$.
