The Autonomic Coumel Triangle: A New Way to Define the Fascinating Relationship between Atrial Fibrillation and the Autonomic Nervous System

open access: yesLife, 2023
Arrhythmogenic substrate, modulating factors, and triggering factors (the so-called Coumel’s triangle concept) play a primary role in atrial fibrillation (AF) pathophysiology. Several years have elapsed since Coumel and co-workers advanced the concept of

The effect of visual-field difference for visual search on selective attention

open access: yesJournal of Human Environmental Studies, 2007
The aim of this study was to investigate the validity of Lavie's load theory (Lavie, 2005) from the point of view of cerebral lateralization. In Experiment 1, right-handed participants were asked to discriminate a target letter in a task-relevant ...

Common Coincidence Points and Common Fixed Points in Fuzzy Semi-Metric Spaces

open access: yesMathematics, 2018
We propose the so-called fuzzy semi-metric space in which the symmetric condition is not assumed to be satisfied. In this case, there are four kinds of triangle inequalities that should be considered.

Families of Integral Cographs within a Triangular Array

open access: yesSpecial Matrices, 2020
The determinant Hosoya triangle, is a triangular array where the entries are the determinants of two-by-two Fibonacci matrices. The determinant Hosoya triangle mod 2 gives rise to three infinite families of graphs, that are formed by complete product ...

Improving the Evapotranspiration Estimation under Cloudy Condition by Extending the Ts-VI Triangle Model

open access: yesRemote Sensing, 2021
Evapotranspiration (ET) of soil-vegetation system is the main process of the water and energy exchange between the atmosphere and the land surface. Spatio-temporal continuous ET is vitally important to agriculture and ecological applications.

From Coalgebra to Bialgebra for the Six-Vertex Model: The Star-Triangle Relation as a Necessary Condition for Commuting Transfer Matrices

open access: yesAxioms, 2012
Using the most elementary methods and considerations, the solution of the star-triangle condition (a2+b2-c2)/2ab = ((a’)^2+(b’)^2-(c’))^2/2a’b’ is shown to be a necessary condition for the extension of the operator coalgebra of the six-vertex model to a ...

ISOSCELES TRIANGLES ON THE SIDES OF A TRIANGLE

open access: yesHuman Research in Rehabilitation, 2019
Famous construction of Fermat-Toricelly point of a triangle leads to the question is there a similar way to construct other isogonic centers of a triangle in a similar way.

Towards a Categorical Account of Conditional Probability [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2015
This paper presents a categorical account of conditional probability, covering both the classical and the quantum case. Classical conditional probabilities are expressed as a certain "triangle-fill-in" condition, connecting marginal and joint ...

Bilateral Grynfeltt lumbar hernia: a case report

open access: yesJournal of Medical Case Reports, 2023
Introduction Lumbar hernias are rare, with only 200–300 published cases listed in the literature. Two areas are described to have weakness points: the inferior lumbar triangle (Jean-Louis Petit triangle) and the superior lumbar triangle (Grynfeltt ...

Morphometrics of Xenopus laevis Kept as Laboratory Animals

open access: yesAnimals, 2022
Morphometric data that provide information on body conditions can be used to monitor the health and well-being of animals. In laboratory animals, they can help to evaluate the stress due to experiments or treatments, following the 3R principles.
