Diagnóstico fractal de disfunción cardíaca severa. Dinámica fractal de la ramificación coronaria izquierda

Revista Colombiana de Cardiología, 2012
la geometría fractal evalúa la irregularidad de los objetos naturales, permitiendo caracterizar de forma imparcial la totalidad de la ramificación coronaria izquierda a diferencia de la metodología actual que evalúa únicamente partes de ésta. Con base en

Review of Fractal and Fractal Derivatives in relation to the Physics of Fractals

, 2013
Fractional and fractal derivatives are both generalizations of the usual derivatives that consider derivatives of non-integer orders. Interest in these generalizations has been triggered by a resurgence of clamor to develop a mathematical tool to describe “roughness” in the spirit of Mandelbrot’s (1967) Fractal Geometry. Fractional derivatives take the

Microscopic Endurance of Rubber Compounds Investigated by In Situ Ultra Small‐Angle X‐Ray Scattering

Journal of Applied Polymer Science, EarlyView.
This study compares the differences in the formation of cavities and the deformation behaviour of silica filler clusters in UHSA and Ultrasil‐VN3 silica‐filled rubbers under strain. The figure illustrates cluster elongation as a function of strain for various silica volume fractions, alongside a visual representation.

Tooth eruption status and bite force determine dental microwear texture gradients in albino rats (Rattus norvegicus forma domestica)

The Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) is widely applied for inferring diet in vertebrates. Besides diet and ingesta properties, factors like wear stage and bite force may affect microwear formation, potentially leading to tooth position‐specific microwear patterns.

Dietary ecology of Smilodon across time and space: Additional perspectives from Smilodon gracilis and Smilodon fatalis in Florida

The Anatomical Record, EarlyView.
Dental microwear texture analysis of Smilodon samples from Florida's Pleistocene reveals moderate carcass utilization (like modern African lions) across space and time, with more subtle dietary shifts in response to fluctuating climates. Abstract Smilodon, the iconic saber‐toothed cat, was a Pleistocene apex predator comprised of three morphologically ...

Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part II Deriving instrument‐specific correction equations for meta‐analyses using published data

The Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has emerged as a valuable method for investigating the feeding ecology of vertebrates. Over the past decade, three‐dimensional topographic data from microscopic regions of tooth surfaces have been collected, and surface texture parameters have been published for both extant and fossil species.

Fractal Image Interpolation: A Tutorial and New Result

Fractal and Fractional, 2019
This paper reviews the implementation of fractal based image interpolation, the associated visual artifacts of the interpolated images, and various techniques, including novel contributions, that alleviate these awkward visual artifacts to achieve ...

Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part I Reproducibility of diet inference using different instruments

The Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has become a well‐established method for dietary inference and reconstruction in both extant and extinct mammals and other tetrapods. As the volume of available data continues to grow, researchers could benefit from combining published data from various studies to perform meta‐analyses.
