Biomechanical Effects of Cage Position in Full-endoscopic Trans-Kambin's Triangle Lumbar Interbody Fusion: A Finite Element Analysis [PDF]

open access: yesNeurologia Medico-Chirurgica
Full-endoscopic trans-Kambin's triangle lumbar interbody fusion is considered a minimally invasive procedure. The cage position in Kambin's triangle lumbar interbody fusion differs from that in other types of lumbar interbody fusion; the cage is inserted

New formulas in area [PDF]

open access: yesمجلة تربويات الرياضيات, 2016
The use of geometric spaces is very important in our lives In ancient times it was used many steps to resolve the area of the triangle, but this research is easy to solve the area of triangle  with one side and  two angles, and it saves time and effort ...

New Diagonal Graph Ramsey Numbers of Unicyclic Graphs

open access: yesTheory and Applications of Graphs, 2023
Grossman conjectured that R(G, G) = 2 · |V (G)| − 1, for all simple connected unicyclic graphs G of odd girth and |V (G)| ≥ 4. In this note, we prove his conjecture for various classes of G containing a triangle.

Periodic balanced binary triangles [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2017
A binary triangle of size $n$ is a triangle of zeroes and ones, with $n$ rows, built with the same local rule as the standard Pascal triangle modulo $2$.

Finite element implementation of general triangular mesh for Riesz derivative

open access: yesPartial Differential Equations in Applied Mathematics, 2021
In this work, we will study a calculation method of variation formula with Riesz fractional derivative. As far as we know, Riesz derivative is a non-local operator including 2ndirections in n−dimension space, which the difficulties for computation of ...

Modeling Spheres in Some Paranormed Sequence Spaces

open access: yesMathematics, 2022
We introduce a new sequence space hA(p), which is not normable, in general, and show that it is a paranormed space. Here, A and p denote an infinite matrix and a sequence of positive numbers.

Diagrammar of physical and fake particles and spectral optical theorem

open access: yesJournal of High Energy Physics, 2021
We prove spectral optical identities in quantum field theories of physical particles (defined by the Feynman iϵ prescription) and purely virtual particles (defined by the fakeon prescription).

Semi-Poisson Statistics in Relativistic Quantum Billiards with Shapes of Rectangles

open access: yesEntropy, 2023
Rectangular billiards have two mirror symmetries with respect to perpendicular axes and a twofold (fourfold) rotational symmetry for differing (equal) side lengths.

Geographic distribution patterns of species of the subtribe Lychnophorinae (Asteraceae: Vernonieae)

open access: yesRodriguésia, 2021
With 119 species distributed in 19 genera, most species of the subtribe Lychnophorinae are endemic to the Espinhaço Range in central eastern Brazil.

Simulation, Seriation and the Dating of Roman Republican Coins

open access: yesJournal of Computer Applications in Archaeology, 2022
Seriation was one of the earliest applications of computers to an archaeological problem. Despite the origins of the technique in numismatics, the vast majority of coinage studies manually sequence coin hoards and issues.
