Enhanced analysis of gating latency in 0.35T MR‐linac through innovative time synchronization of a motion phantom and plastic scintillation detector

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose This study aims to evaluate how different gantry angles, breathing rates (BPM), cine image speeds, and tracking algorithms affect beam on/off latency and the subsequent impact on target dose for a 0.35T MR‐Linac with a 6 MV FFF beam.

Light Graphs In Planar Graphs Of Large Girth

open access: yesDiscussiones Mathematicae Graph Theory, 2016
A graph H is defined to be light in a graph family 𝒢 if there exist finite numbers φ(H, 𝒢) and w(H, 𝒢) such that each G ∈ 𝒢 which contains H as a subgraph, also contains its isomorphic copy K with ΔG(K) ≤ φ(H, 𝒢) and ∑x∈V(K) degG(x) ≤ w(H, 𝒢).

An Analogue of DP-Coloring for Variable Degeneracy and its Applications

open access: yesDiscussiones Mathematicae Graph Theory, 2022
A graph G is list vertex k-arborable if for every k-assignment L, one can choose f(v) ∈ L(v) for each vertex v so that vertices with the same color induce a forest. In [6], Borodin and Ivanova proved that every planar graph without 4-cycles adjacent to 3-

On Subexponential Parameterized Algorithms for Steiner Tree and Directed Subset TSP on Planar Graphs

open access: yesIEEE Annual Symposium on Foundations of Computer Science, 2017
There are numerous examples of the so-called "square root phenomenon" in the field of parameterized algorithms: many of the most fundamental graph problems, parameterized by some natural parameter k, become significantly simpler when restricted to planar

On the Neighbor Sum Distinguishing Index of Planar Graphs [PDF]

open access: yesJournal of Graph Theory, 2014
Let c be a proper edge coloring of a graph G=(V,E) with integers 1,2,…,k . Then k≥Δ(G) , while Vizing's theorem guarantees that we can take k≤Δ(G)+1 .

Data‐driven forecasting of ship motions in waves using machine learning and dynamic mode decomposition

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
Summary Data‐driven forecasting of ship motions in waves is investigated through feedforward and recurrent neural networks as well as dynamic mode decomposition. The goal is to predict future ship motion variables based on past data collected on the field, using equation‐free approaches.

SOME PROPERTIES ON COPRIME GRAPH OF GENERALIZED QUATERNION GROUPS

open access: yesBarekeng, 2023
A coprime graph is a representation of finite groups on graphs by defining the vertex graph as an element in a group and two vertices adjacent to each other's if and only if the order of the two elements is coprime.

Soft‐Layered Composites with Wrinkling‐Activated Multi‐Linear Elastic Behavior, Stress Mitigation, and Enhanced Strain Energy Storage

open access: yesAdvanced Engineering Materials, EarlyView.
In this study, exciting new bi‐/multi‐linear elastic behavior of soft elastic composites that accompany the activation of wrinkling in the embedded interfacial layers is analyzed. The new features and performance of these composite materials, including dramatic enhancements in energy storage, can be tailored by the concentration of interfacial layers ...

On the Recognition of Fan-Planar and Maximal Outer-Fan-Planar Graphs [PDF]

open access: yesAlgorithmica, 2014
Fan-planar graphs were recently introduced as a generalization of 1-planar graphs. A graph is fan-planar if it can be embedded in the plane, such that each edge that is crossed more than once, is crossed by a bundle of two or more edges incident to a ...
