About Structure of Graph Obstructions for Klein Surface with 9 Vertices

open access: yesКібернетика та комп'ютерні технології, 2020
The structure of the 9 vertex obstructive graphs for the nonorientable surface of the genus 2 is established by the method of (-transformations of the graphs.

Drawing Partially Embedded and Simultaneously Planar Graphs

open access: yes, 2014
We investigate the problem of constructing planar drawings with few bends for two related problems, the partially embedded graph (PEG) problem—to extend a straight-line planar drawing of a subgraph to a planar drawing of the whole graph—and the ...

Testing first-order properties for subclasses of sparse graphs [PDF]

open access: yes, 2013
We present a linear-time algorithm for deciding first-order (FO) properties in classes of graphs with bounded expansion, a notion recently introduced by Nešetřil and Ossona de Mendez.

Intrinsic Photoactive Star ZnPc–Poly(glutamate) Nanoplatforms for Multimodal Glioblastoma Therapy and Brain‐Targeted Delivery

open access: yesAdvanced Functional Materials, EarlyView.
An intrinsic photoactive star‐shaped zinc phtalocyanine‐poly(L‐glutamic acid) (ZnPc‐PGA) nanoplatform for multimodal glioblastoma (GBM) therapy and brain‐targeted elivery. A ZnPc‐PGA‐based multifunctional theranostic nanocarrier platform enables image‐guided, multimodal GBM therapy. ZnPc‐PGA nanocarriers support the integration of fluorescence imaging,

The maximum number of edges of bipartite 1-planar graphs with 1-disk drawings

open access: yesAKCE International Journal of Graphs and Combinatorics
A graph is 1-planar if it admits a drawing in the plane such that each edge is crossed at most once. Let G be a bipartite 1-planar graph with bipartition sets X and Y. A 1-disk [Formula: see text] drawing of G is a 1-planar drawing such that all vertices

On the planarity of jump graphs

open access: yesDiscrete Mathematics, 2000
Let \(G\) be a graph of size \(m\geq 1\) and let \(F\) and \(H\) be edge-induced subgraphs of \(G\) of size \(k\) with \(1\leq k\leq m\). In the literature is then defined the \(k\)-jump distance from \(F\) to \(H\). For a graph \(G\) of size \(m\geq 1\) and an integer \(k\) with \(1\leq k\leq m\), the \(k\)-jump graph \(J_k(G)\) is defined as a graph ...

Texoskeletons: Developing the Fundamental Technologies for Creating Intelligent Soft Robotic Clothing With Integrated 1D Sensors and Actuators

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Traditional wearable exoskeletons rely on rigid structures, which limit comfort, flexibility, and everyday usability. This work introduces the fundamental technologies to create the first soft, lightweight, intelligent textile‐based exoskeletons (Texoskeletons) built using 1D sensors and actuators.

Transfer Printing and Reconfiguration of Soft Electronics Using Digital Microfluidics and Laser Machining

open access: yesAdvanced Functional Materials, EarlyView.
This paper presents a digital microfluidics‐based technique for transferring and reconfiguring soft nanomembranes. Laser‐machined nanothin membranes are picked up, transported, and aligned via tailored surface tension and the actuation of water droplets, enabling the development of flexible electronics, the integration of functional materials on 3D ...

Clique Planar Graphs

open access: yesElectronic Notes in Discrete Mathematics, 2001
Abstract Abstract We generalize the idea of extended triangles of a graph G by considering a family of completes of G instead of the clique family of G. We characterize Helly and 3 - Helly Planar Graphs using extended triangles. We prove that if a planar graph is a clique graph then any one of its extended triangles is a clique graph.

Morphing Planar Graph Drawings via Orthogonal Box Drawings [PDF]

open access: yes
We give an algorithm to morph planar graph drawings that achieves small grid size at the expense of allowing a constant number of bends on each edge. The input is an n-vertex planar graph and two planar straight-line drawings of the graph on an O(n) × O ...
