RUHS Journal of Health Science, 2023 Introduction: The goal of this study was to develop a novel cephalometric estimation to assess the sagittal relationship between the maxilla and mandible. Methodology: Fifty pre-treatment lateral cephalograms were chosen and classified into classes I, II, and III based on ANB angle, W angle, Beta angle, and Pi angle.

A New Angle on the Angle of Louis [PDF]
Congestive Heart Failure, 2006 Previous literature has stated that the center of the right atrium lies approximately 5 cm below the sternal angle regardless of body position. Our objective was to measure the distance from the Angle of Louis to various locations in the right atrium and determine whether these distances vary with patients' body habitus.

The American Mathematical Monthly, 2009 We use a probabilistic interpretation of solid angles to generalize the well-known fact that the inner angles of a triangle sum to 180 degrees. For the 3-dimensional case, we show that the sum of the solid inner vertex angles of a tetrahedron T, divided by 2*pi, gives the probability that an orthogonal projection of T onto a random 2-plane is a ...

Fused Angles and the Deficiencies of Euler Angles [PDF]
2018 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2018 Just like the well-established Euler angles representation, fused angles are a convenient parameterisation for rotations in three-dimensional Euclidean space. They were developed in the context of balancing bodies, most specifically walking bipedal robots, but have since found wider application due to their useful properties.

Multispecies fish tracking across newly created shallow and deep habitats in a forward-restored lake
Movement Ecology, 2023 Background Freshwater fish communities typically thrive in heterogenous ecosystems that offer various abiotic conditions. However, human impact increasingly leads to loss of this natural heterogeneity and its associated rich fish communities.

Israel Journal of Mathematics, 2016 We consider the following question. Suppose that $d\ge2$ and $n$ are fixed, and that $θ_1,θ_2,\dots,θ_n$ are $n$ specified angles. How many points do we need to place in $\mathbb{R}^d$ to realise all of these angles? A simple degrees of freedom argument shows that $m$ points in $\mathbb{R}^2$ cannot realise more than $2m-4$ general angles.

Potential Factors Limiting Brown Trout Catches by Anglers - A Case Study
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2021 In recent years, the numbers of native brown trout caught by anglers has declined throughout the Czech Republic. In this study, we focus on individual factors potentially related to this negative trend, based primarily on long-term angling catch data ...

On Angles and Pseudo-Angles in Minkowskian Planes [PDF]
Mathematics, 2018 The main purpose of the present paper is to well define Minkowskian angles and pseudo-angles between the two null directions and between a null direction and any non-null direction, respectively. Moreover, in a kind of way that will be tried to be made clear at the end of the paper, these new sorts of angles and pseudo-angles can similarly to the ...

First assimilations of COSMIC radio occultation data into the Electron Density Assimilative Model (EDAM) [PDF]
Annales Geophysicae, 2008 Ground based measurements of slant total electron content (TEC) can be assimilated into ionospheric models to produce 3-D representations of ionospheric electron density.
