Embedding graphs on Grassmann manifold

open access: yesNeural Networks, 2022
Learning efficient graph representation is the key to favorably addressing downstream tasks on graphs, such as node or graph property prediction. Given the non-Euclidean structural property of graphs, preserving the original graph data's similarity relationship in the embedded space needs specific tools and a similarity metric.

Some Results On Convex Greedy Embedding Conjecture for 3-Connected Planar Graphs

open access: yes, 2009
A greedy embedding of a graph $G = (V,E)$ into a metric space $(X,d)$ is a function $x : V(G) \to X$ such that in the embedding for every pair of non-adjacent vertices $x(s), x(t)$ there exists another vertex $x(u)$ adjacent to $x(s)$ which is closer to $

Distributed social graph embedding [PDF]

open access: yesProceedings of the 20th ACM international conference on Information and knowledge management, 2011
La recommandation de contenu est devenue un élément central de l'Internet moderne pour permettre aux utilisateurs de naviguer parmi la masse d'information à leur disposition. Dans ce papier, nous proposons un algorithme décentralisé appelé \textsc{SoCS (Social Coordinate Systems}) qui permet de plonger un graphe social dans un espace Euclidien afind ...

Dynamic Planar Embeddings of Dynamic Graphs

open access: yes, 2017
We present an algorithm to support the dynamic embedding in the plane of a dynamic graph. An edge can be inserted across a face between two vertices on the face boundary (we call such a vertex pair linkable), and edges can be deleted.

Corrigendum to "Embedding Graphs into Colored Graphs" [PDF]

open access: yesTransactions of the American Mathematical Society, 1992
The authors give a corrected exposition of the proof of Theorem 12 of their quoted paper [ibid. 307, No. 1, 395-409 (1988; Zbl 0659.03029)].

Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Time2Graph: Dual Embedding and Nested-Graph Transformation for Performance Enhancement in Time Series Classification

open access: yesIEEE Access
In this paper, we propose Time2Graph, a novel graph-based classification model designed to improve time series classification(TSC) performance in graph environments. Time2Graph applies a nested graph construction to effectively analyze time series in the

Embedding of metric graphs on hyperbolic surfaces

open access: yes, 2018
An embedding of a metric graph $(G, d)$ on a closed hyperbolic surface is \emph{essential}, if each complementary region has a negative Euler characteristic.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Constant approximation algorithms for embedding graph metrics into trees and outerplanar graphs

open access: yes, 2010
In this paper, we present a simple factor 6 algorithm for approximating the optimal multiplicative distortion of embedding a graph metric into a tree metric (thus improving and simplifying the factor 100 and 27 algorithms of B\v{a}doiu, Indyk, and ...
