Temporal lift with repositioning of the orbicular muscle and eyebrow tail [PDF]

open access: yesRevista Brasileira de Cirurgia Plástica, 2022
Introduction: The superficial musculoaponeurotic system (SMAS) is the best structure we have at our disposal to elevate and reposition the face and neck in the facelift. However, in the temporoorbital region, this structure is often neglected.

Identities for Fibonacci and Lucas numbers [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics, 2023
In this paper several new identities are given for the Fibonacci and Lucas numbers. This is accomplished by by solving a class of non-homogeneous, linear recurrence relations.

A note on generating primitive Pythagorean triples using matrices [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics, 2023
We present matrices that generate families of primitive Pythagorean triples that arise from generalized Fibonacci sequences. We then present similar results for generalized Lucas sequences and primitive Pythagorean triples.

Statistics on restricted Fibonacci words [PDF]

open access: yesTransactions on Combinatorics, 2021
We study two foremost Mahonian statistics, the major index and the inversion number for a class of binary words called restricted Fibonacci words. The language of restricted Fibonacci words satisfies recurrences which allow for the calculation of the ...

Non-Bragg band gaps in 1D metamaterial aperiodic multilayers [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2007
We investigate the existence of non–Bragg band gaps in 1D aperiodic photonic structures, namely the Fibonacci and Thue–Morse lattices combining ordinary positive index materials and dispersive metamaterials.

Fibonacci, Golden Ratio, and Vector Bundles

open access: yesMathematics, 2021
There is a family of vector bundles over the moduli space of stable curves that, while first appearing in theoretical physics, has been an active topic of study for algebraic geometers since the 1990s. By computing the rank of the exceptional Lie algebra

Kajian Morfisme Untuk Variasi Kurva Dense Fibonacci Word

open access: yesJurnal Matematika, 2021
The Fibonacci word is one example of a fractal object. The fractal Fibonacci word has the property of being similar to curves with curves. The curve Fibonacci word generated based on the Fibonacci word sequence. The Fibonacci word sequence can be defined

Fibonacci's mathematical sequence predicts functional and actual lengths of the phalanges of the hand

open access: yesJournal of Nature and Science of Medicine, 2021
Background: Fibonacci described a mathematical sequence starting 0, 1, 1, 2, 3, 5, 8… where each sub sequential number is the sum of the two preceding numbers.
