On the planar edge-length ratio of planar graphs

open access: yesJ. Comput. Geom., 2019
The edge-length ratio of a straight-line drawing of a graph is the ratio between the lengths of the longest and of the shortest edge in the drawing. The planar edge-length ratio of a planar graph is the minimum edge-length ratio of any planar straight-line drawing of the graph. In this paper, we study the planar edge-length ratio of planar graphs.

Strip Planarity Testing

open access: yes, 2013
In this paper we introduce and study the strip planarity testing problem, which takes as an input a planar graph G(V,E) and a function γ:V → {1,2,…,k} and asks whether a planar drawing of G exists such that each edge is monotone in the y-direction and ...

Constrained Planarity in Practice -- Engineering the Synchronized Planarity Algorithm [PDF]

open access: yes, 2023
In the constrained planarity setting, we ask whether a graph admits a planar drawing that additionally satisfies a given set of constraints. These constraints are often derived from very natural problems; prominent examples are Level Planarity, where ...

Comparative study of resonance-inhibited hydrogen bonded (RIHB) systems with different atoms involved: the leading role of σ-planarity

open access: yes, 2019
O, S, Se, and P atoms are considered as different proton donor/acceptor moieties in the resonance-inhibited hydrogen bonded (RIHB) interactions to conduct a comparative investigation.

Clustered Planarity with Pipes [PDF]

open access: yes, 2016
We study the version of the C-Planarity problem in which edges connecting the same pair of clusters must be grouped into pipes, which generalizes the Strip Planarity problem. We give algorithms to decide several families of instances for the two variants

A Multiview Stereo Algorithm Based on Image Segmentation Guided Generation of Planar Prior for Textureless Regions of Artificial Scenes

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
Textureless building surfaces composed of homogenized pixels could lead to failure of photometric consistency. However, textureless regions widely present in artificial scenes usually exhibit strong planarity enabling depth estimation of textureless ...

In silico and in vitro exploration of a tyrosinase for biocatalytic production of catechols

open access: yesFEBS Open Bio, EarlyView.
Tyrosinase from Ralstonia pseudosolanacearum is a promising biocatalyst for producing valuable catechols from monophenol substrates. This tyrosinase is uniquely suited to this due to its high monophenolase : diphenolase ratio. We combined in silico docking and in vivo kinetic characterisation of this tyrosinase with 11 industrially relevant monophenols,

Subgraph Homeomorphism via the Edge Addition Planarity Algorithm

open access: yesJournal of Graph Algorithms and Applications, 2012
This paper extends the edge addition planarity algorithm from Boyer and Myrvold to provide a new way of solving the subgraph homeomorphism problem for K2,3, K4, and K3,3.

White Matter and Perivascular Imaging Changes in Alzheimer's Disease and Cerebral Amyloid Angiopathy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Peak‐width of skeletonized mean diffusivity (PSMD) and diffusion tensor imaging–analysis along the perivascular space (DTI‐ALPS), reflecting white matter integrity and glymphatic function, are altered in Alzheimer's disease (AD).
