Signed Graph Metric Learning via Gershgorin Disc Perfect Alignment [PDF]

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2020
Given a convex and differentiable objective $Q({\mathbf M})$Q(M) for a real symmetric matrix ${\mathbf M}$M in the positive definite (PD) cone—used to compute Mahalanobis distances—we propose a fast general metric learning framework that is entirely ...

Open String Diagrams I: Topological Type [PDF]

open access: yes, 1992
An arbitrary Feynman graph for string field theory interactions is analysed and the homeomorphism type of the corresponding world sheet surface is completely determined even in the non-orientable cases.

An algorithmic approach to signed fuzzy graph integrity: Complexity, graph operations, and metro rail network applications

open access: yesAin Shams Engineering Journal
This paper presents an algorithm to compute the integrity of a signed fuzzy graph by systematically evaluating vertex subsets, removing them, and analyzing the resulting connected components.

Hostile-based bipartite containment control of nonlinear fractional multi-agent systems with input delays: a signed graph approach under disturbance and switching networks

open access: yesAIMS Mathematics
This article addresses the hostile-based bipartite containment control of nonlinear fractional multi-agent systems (FMASs) with input delays. Several fundamental algebraic criteria have been offered by the use of signed graph theory.

On balanced cycle domination of graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2023
Let [Formula: see text] be a graph. A function [Formula: see text] is said to be a balanced cycle dominating function (BCDF) of [Formula: see text] if [Formula: see text] holds for any induced cycle [Formula: see text] of [Formula: see text] The balanced

The Caenorhabditis elegans DPF‐3 and human DPP4 have tripeptidyl peptidase activity

open access: yesFEBS Letters, EarlyView.
The dipeptidyl peptidase IV (DPPIV) family comprises serine proteases classically defined by their ability to remove dipeptides from the N‐termini of substrates, a feature that gave the family its name. Here, we report the discovery of a previously unrecognized tripeptidyl peptidase activity in DPPIV family members from two different species.

Characterizing the salivary RNA landscape to identify potential diagnostic, prognostic, and follow‐up biomarkers for breast cancer

open access: yesMolecular Oncology, EarlyView.
This study explores salivary RNA for breast cancer (BC) diagnosis, prognosis, and follow‐up. High‐throughput RNA sequencing identified distinct salivary RNA signatures, including novel transcripts, that differentiate BC from healthy controls, characterize histological and molecular subtypes, and indicate lymph node involvement.

Spectrum-based deep neural networks for fraud detection

open access: yes, 2017
In this paper, we focus on fraud detection on a signed graph with only a small set of labeled training data. We propose a novel framework that combines deep neural networks and spectral graph analysis. In particular, we use the node projection (called as

Integrated genomic and proteomic profiling reveals insights into chemoradiation resistance in cervical cancer

open access: yesMolecular Oncology, EarlyView.
A comprehensive genomic and proteomic analysis of cervical cancer revealed STK11 and STX3 as a potential biomarkers of chemoradiation resistance. Our study demonstrated EGFR as a therapeutic target, paving the way for precision strategies to overcome treatment failure and the DNA repair pathway as a critical mechanism of resistance.

On the signed Italian domination of graphs [PDF]

open access: yesComputer Science Journal of Moldova, 2019
A signed Italian dominating function on a graph $G=(V,E)$ is a function $f:V\to \{ -1, 1, 2 \}$ satisfying the condition that for every vertex $u$, $f[u]\ge 1$. The weight of signed Italian dominating function is the value $f(V)=\sum_{u\in V}f(u)$.
