Trees are loosely fractal. While the trunks dont keep replicating, the branches do. As the Fractal Explorer observes:. If you dont know anything about fractals a tree might seem as a very random object. No patterns, no rules. But if you know something about fractals and look closer you can see that basically a tree is a trunk with trees on it. That is a basic pattern that every tree follows.. Taxonomies are often described as taxonomic trees, or as having a tree-like structure. To carry the analogy further, we often refer to the progressively more specific and more numerous hierarchical subdivisions in a taxonomy as branches. The overall domain of a taxonomy, while sometimes referred to as its root, might also be viewed as its trunk.. So this begs the question: Are taxonomies fractal? As it turns out, several authors have written articles on the fractal nature of biological genus-and-species taxonomies. These articles discuss the branching characteristics of these taxonomies, the same ...

In computer graphics fractals are helpful in correctly representing objects from nature. Primitive shapes are simple to express with 2D and 3D technology. For more complex images such as trees or clouds, the computer graphics industry is using fractal techniques to attempt to recreate these objects. There are a multiple ways that a series can behave. It can go into infinity, decrease to zero, move back and forth between numbers, or just not have a clear pattern. To model the nature in the world we live in, mathematicians and computer scientists create functions for each type of fractal and modify it to look a certain way. Fractals are now becoming a very important part of computer graphics ...

Fractals and Chaos in Geology and Geophysics, Second Edition, is the best technical introduction to chaos known to me. It is suitable not only for geologists, but for anyone who is seriously interested in the subject. The title of the book is misleadingly narrow; its content would be better described by the unwieldy title Concepts and Application of Chaos Theory, with an even longer subtitle Examples Taken Predominantly from the Earth Sciences. The mathematics are simple; a second-year college student should be fully capable of handling the book. ...

Steady state laser light propagation in diffuse media such as biological cells generally provide bulk parameter information, such as the mean free path and absorption, via the transmission profile. The accompanying optical speckle can be analyzed as a random spatial data series and its fractal dimension can be used to further classify biological media that show similar mean free path and absorption properties, such as those obtained from a single population. A population of yeast cells can be separated into different portions by centrifuge, and microscope analysis can be used to provide the population statistics. Fractal analysis of the speckle suggests that lower fractal dimension is associated with higher cell packing density. The spatial intensity correlation revealed that the higher cell packing gives rise to higher refractive index. A calibration sample system that behaves similar as the yeast samples in fractal dimension, spatial intensity correlation and diffusion was selected. Porous ...

The retinal vascular tree is a complex branching structure that cannot be sufficiently described using the classical Euclidian geometric terms. Fractals, on the other hand, represent a type of non-Euclidian geometric shape that has been applied in many aspects of medicine to describe similarly complex branching biological structures (e.g., coronary arterioles or pulmonary bronchi). Fractals can be defined as geometric patterns whose parts resemble the whole (i.e., the property of self-similarity), and fractal dimension is a measure of the geometric complexity of a spatial object. The retinal vascular tree is a fractal object (9-14). Fractal analysis of the retinal vasculature has been performed in previous studies that provided insights into the embryology and development of retinal vessels (13).. In this study, we found that increased fractal dimension of the retinal vasculature, reflecting increased geometric complexity of the retinal vascular branching pattern, is associated with early ...

The fern is one of the basic examples of self-similar sets, i.e. it is a mathematically generated pattern that can be reproducible at any magnification or reduction. Like the Sierpinski triangle, the Barnsley fern shows how graphically beautiful structures can be built from repetitive uses of mathematical formulas with computers. Barnsleys 1988 book Fractals Everywhere is based on the course which he taught for undergraduate and graduate students in the School of Mathematics, Georgia Institute of Technology, called Fractal Geometry. After publishing the book, a second course was developed, called Fractal Measure Theory.[1] Barnsleys work has been a source of inspiration to graphic artists attempting to imitate nature with mathematical models.. The fern code developed by Barnsley is an example of an iterated function system (IFS) to create a fractal. This follows from the collage theorem. He has used fractals to model a diverse range of phenomena in science and technology, but most specifically ...

The word fractal often has different connotations for the lay public as opposed to mathematicians, where the public are more likely to be familiar with fractal art than the mathematical concept. The mathematical concept is difficult to define formally, even for mathematicians, but key features can be understood with little mathematical background. The feature of self-similarity, for instance, is easily understood by analogy to zooming in with a lens or other device that zooms in on digital images to uncover finer, previously invisible, new structure. If this is done on fractals, however, no new detail appears; nothing changes and the same pattern repeats over and over, or for some fractals, nearly the same pattern reappears over and over.[5] Self-similarity itself is not necessarily counter-intuitive (e.g., people have pondered self-similarity informally such as in the infinite regress in parallel mirrors or the homunculus, the little man inside the head of the little man inside the head ...

This dissertation tackles the problem of non-normality in the distribution of returns and attempts to formulate a proprietary trading strategy to arbitrage the markets using appropriate statistical and mathematical tools. The first essay provides fundamental understanding to fractional Brownian motion (fBm) process, its characteristic Hurst exponent, and the concept of unit root in time series data. The study shows that a simple autoregressive (AR) process with suitable lag coefficients is able to effectively replicate the fractal time series and preserves its characteristic Hurst exponent. More interestingly, an equation that defines the relationship between the AR lag coefficients and the Hurst exponent that described a particular fBm process is also derived. The second essay introduces the concept of excursion measures and illustrates how the Itô‟s excursion theory can be used as a tool to understanding fractals. The excursionsvalued process is shown to follow a binomial distribution which ...

PET/CT with F-18-fluorodeoxyglucose (FDG) images of patients suffering from metastatic melanoma have been analysed using fractal and multifractal analysis to assess the impact of monoclonal antibody ipilimumab treatment with respect to therapy outcome. Thirty-one cases of patients suffering from metastatic melanoma have been scanned before and after two and after four cycles of treatment. For each patient, we calculated the fractal and multifractal dimensions using the box-counting method on the digitalised PET/CT images of all three studies to assess the therapeutic outcome. We modelled the spreading of malignant cells in the body via kinetic Monte Carlo simulations to address the dynamical evolution of the metastatic process and to predict the spatial distribution of malignant lesions. Our analysis shows that the fractal dimensions which describe the tracer dispersion in the body decrease consistently with the deterioration of the patients therapeutic outcome condition. In 20 out of 24 cases, the

Purpose: To investigate the correlation between the retinal vascular fractal dimension (Fd) and neurodegenerative changes in patients with no or mild diabetic retinopathy (DR). Methods: In this cross-sectional study we examined 103 patients with type 2 diabetes mellitus (T2DM) with no or mild DR. In a randomly selected eye of each patient, Fd was calculated using SIVA-Fractal, a specialized semiautomatic software. Retinal neurodegeneration was evaluated by Topcon 3D OCT-2000 spectral-domain optical coherence tomography (OCT) and by a RETI-scan multifocal ERG (mf-ERG) system in rings one to six. Level of DR was determined by a single trained grader in seven-field fundus photos according to the Early Treatment Diabetic Retinopathy Study (ETDRS) scale. Results: Mean age and duration of T2DM were 62.3 and 11.6 years, respectively; 46.6% were men. Mean Fd was 1.413 (range, 1.278-1.509) and ETDRS levels were 10 (42.7%), 20 (35.0%), and 35 (22.3%), respectively. Fd correlated inversely with mf-ERG ...

In this paper, a novel fast method for modeling mammograms by deterministic fractal coding approach to detect the presence of microcalcifications, which are early signs of breast cancer, is presented. The modeled mammogram obtained using fractal encoding method is visually similar to the original image containing microcalcifications, and therefore, when it is taken out from the original mammogram, the presence of microcalcifications can be enhanced. The limitation of fractal image modeling is the tremendous time required for encoding. In the present work, instead of searching for a matching domain in the entire domain pool of the image, three methods based on mean and variance, dynamic range of the image blocks, and mass center features are used. This reduced the encoding time by a factor of 3, 89, and 13, respectively, in the three methods with respect to the conventional fractal image coding method with quad tree partitioning. The mammograms obtained from The Mammographic Image Analysis ...

Ecological estimates of the number of species at large scales come from a hypothetical curve based on fractals, which predicts that the number of species will increase with area, but increase more slowly for larger and larger areas - a power-law rise with the number of species proportional to the ¼ power of the area.. You can sample an area and count the number of species, and then double the area and find more species, but not twice as many, because the species overlap, Harte said.. He and colleague Jessica Green showed in 2003 that the theory of fractals, which posits that physical patterns such as the distribution of plants look similar on small and large scales, does not explain species richness over large areas. In addition, experimental tests of the species-area relationship showed that the curve has to be tweaked for every class of organisms and habitat studied.. Harte and colleagues Adam Smith of UC Berkeley and David Storch of Charles University in Prague, Czech Republic, decided to ...

Easy enough to do. Well, easy enough if you have enough memory to handle very large data sets. Luckily enough, we had just enough memory for this script & data series, and we were happy. The image was generated, and everything worked fine.. Still, we wanted to improve on that. One problem with this visualization is that two horizontally adjacent pixels dont have anything to do with each other. Remembering xkcds Map of the Internet, I decided to use the Hilbert Curve. I started with wikipedias version of the code for the Python turtle and changed it to generate a string of instructions of where to put pixels. On the way I improved the time complexity by changing it to have only two recursion calls instead of four. (It can probably be taken down to one by the way, I leave that as a challenge to the reader :). Unfortunately, at this point we didnt have enough memory to hold all of those instructions, so I changed it into a generator. Now it was too slow. I cached the lower levels of the ...

TY - JOUR. T1 - Inevitable self-similar topology of binary trees and their diverse hierarchical density. AU - Paik, K.. AU - Kumar, P.. PY - 2007/11/1. Y1 - 2007/11/1. N2 - Self-similar topology, which can be characterized as power law size distribution, has been found in diverse tree networks ranging from river networks to taxonomic trees. In this study, we find that the statistical self-similar topology is an inevitable consequence of any full binary tree organization. We show this by coding a binary tree as a unique bifurcation string. This coding scheme allows us to investigate trees over the realm from deterministic to entirely random trees. To obtain partial random trees, partial random perturbation is added to the deterministic trees by an operator similar to that used in genetic algorithms. Our analysis shows that the hierarchical density of binary trees is more diverse than has been described in earlier studies. We find that the connectivity structure of river networks is far from ...

An obstacle to the study of root architecture is the difficulty of measuring and quantifying the three-dimensional configuration of roots in soil. A study was conducted to determine if fractal geometry might be useful in estimating the three-dimensional complexity of root architecture from more accessible measurements. A set of results called projection theorems predict that the fractal dimension (FD) of a projection of a root system should be identical to the FD of roots in three-dimensional space (three-dimensional FD). To test this prediction, SimRoot, an explicit geometric simulation model of root growth derived from empirical measurements of common bean ( Phaseolus vulgaris ), was used. The three-dimensional FD, FD of horizontal plane intercepts (planar FD), FD of vertical line intercepts (linear FD), and FD of orthogonal projections onto planes (projected FD) were calculated. Three-dimensional FD was found to differ from corresponding projected FD, suggesting that the analysis of roots ...

Thermal conductivity of frost is not only related to density, but also affected by its microstructure and environmental conditions, and it will continuously change with the formation and growth of frost. Images of frost formation and growth on the cryogenic surface in various shapes at different stages were obtained by experimental measurements, and a numerical simulation of frost formation and growth was carried out based on Diffusion Limited Aggregation (DLA) model of fractal theory in this paper. Based on the frost structure obtained by experiment, the fractal dimension of pore area distribution and porosity of frost layer on the cryogenic finned-tube vaporizer were calculated by using fractal method, and combined with heat conduction model of frost layer obtained by thermal resistance method, the thermal conductivity of frost on the cryogenic surface was calculated. The result shows that the thermal conductivity calculated by the fractal model coincides with the range of the experimental data.

Abstract. Meiosis, the reductive nuclear division, is a continuum, but for purposes of communication, is described in stages. In sexually-reproducing organisms, including the dwarf mistletoe Arceuthobium americanum, prophase I of meiosis is prolonged (8 months for female A. americanum). Conversely, metaphase I, where chromosome pairs line up along a dividing cells equator, is relatively brief, difficult to predict, but critical regarding the random distribution of the paternal and maternal chromosomes in sexual organisms. However, descriptions of meiosis as either a continuum or stages are limited to qualitative observations. A quantification of meiosis can provide mathematical descriptors and allow for the prediction of when chromosomes reach the equator; this will not only be useful to researchers of cell division, but also to those requiring a large sample of metaphase I materials. Here, the probability-density function was used to calculate the fractal dimension of A. americanum nuclei ...

The sols prepared by mixing a ZrOCl2 acidified solution to a hot H2SO4 aqueous solutions were studied in order to clarify the mechanism of thermoreversible sol-gel transition observed in this system. The viscoelastic properties of these suspensions were analyzed during the sol-gel transition by dynamic rheological measurements and quasi-elastic light scattering. The rheological properties were correlated to mass fractal and nearly linear growth models, and percolation theory. The results evidence that the thermoreversible sol-gel transition in this system is due to the formation of a network of physically linked aggregates having fractal structure. The decrease of the SO42- contents in the initial solution leads to the decrease of the fractal dimensionality from 2.3 to 1.8, indicating a change of the kinetic mechanism of aggregate growth. Near the gel point these samples have the typical scaling expected from percolation theory. (C) 2004 Elsevier B.V. All rights reserved.. ...

Within the presented case-study different disciplines worked together improving the knowledge of the developement of the North German Basin. We focus the area of a producing gas field with special respect to the analysis of seismic and sub-seismic deformation which requires a very detailed fault detection to bridge the information gap between seismic data and well data. Advanced coherency algorithms as Shaded-Relief take into account local dip and azimuth distribution of coherent energy. This leads to detect additional tectonic lineaments than could have been inferred from conventional amplitude images. Beside fracture attributes like fault density by length or connectivity, we show the attribute Fractal Dimension, which is an index for the relation of long to short fractures. Results are displayed in a map showing the areal distribution of the attribute. Correlation between FMI/FMS Log Data and FD values is linear. Using this relation, we end up with a predictive FMI-map (only based on seismic data)

Strong seasonality is observed in the volatile hourly Alberta temperature and its low- and high-order statistical moments. We propose a time series model consisting of a linear combination of an annual sinusoidal model, a diurnal sinusoidal model and a fractional residual model, to study the characteristics of these spatial and time-dependent Alberta temperatures. Wavelet multi-resolution analysis is used to measure Hurst exponents of the temperature series. Our empirical results show that these Hurst exponents vary over various time scales, indicating the existence of multi-fractality in the temperatures. Such temperature models are of importance for the pricing and insurance of agricultural crops, of tourist resorts and of all forms of energy extraction and generation of importance to the resource-based economy of Alberta. Of particular interests are the observed extreme volatilities in the winters, caused by the unpredictable Chinook winds, which may be an important reason to introduce a ...

Dr. Chris Sorensen (Kansas State). Soot, the by-product of combustion, that smoky, black stuff from chimneys, power plants and the inside of the tail pipe of my roadster, what scientist would ever bother to study soot? As a particle physicist, thats what I do, and I find that soot has mysteries and beauties that can entertain any curiosity. In this talk I will describe some of my researches into soot and other aggregate structures; an unlikely journey of discovery to find fractal structures with non-Euclidian dimensionality, gel networks that tenuously span space and common Fibonacci themes between spirals, sunflowers and soot.. ...

The thesis investigates a direct and sensitive method for the detection of biomolecules as indicators of Pseudomonas aeruginosa infection. This is of significant clinical importance for patients with cystic fibrosis (CF) of which Ireland has one of the highest rates in the world per head of population. Cell-to-cell communication (quorum sensing, QS) in P. aeruginosa is an important pathway to triggering biofilms which create added complications for patients. Different conventional analytical methods for the analysis and detection of P. aeruginosa QS signaling molecules exist. An overview of capillary electrophoresis (CE) and the boron-doped diamond (BDD) electrode are given. In this thesis, new approaches to separation and sensing these signaling molecules are developed. A method for the simultaneous separation of signaling molecules PYO, HHQ, and PQS using bare CE coupled with ultraviolet (UV) detection is an example. An optimized method on a bare CE is further applied to the analysis of P. ...

t).. SBM is thus at variance with the currently available experimental observations in complex liquids using single particle tracking by video microscopy or by optical tweezers tracking of single submicron particles. Thus the free anomalous diffusion data garnered so far was classified into FBM-like and CTRW-like behaviour, or combinations thereof.8,10,12 Note that also for fluorescence correlation spectroscopy experiments recent analysis tools corroborated an FBM nature of the data.13 For optical tweezers tracking of lipid granules in different complex liquids the subdiffusive time averaged MSD either continues to grow under confinement, reflecting the non-ergodic features of CTRWs,5,9 or it relaxes to a plateau value mirroring an ergodic dynamics.15,54. How can FBM and SBM have the same distribution (4) in free space? Simply put for FBM, the viscoelastic properties of the environment effecting the long-range correlations of FBM lead to a frequency dependent response of the environment to a ...

Ever since its first formulation in the 1970s the so called chaos theory has held great appeal for the humanities, philosophy and social sciences. Until the late 1990s many literary studies papers inspired by chaos theory included the observation that only time could tell whether the terminological transfer from physics and mathematics could provide the enrichment for the discipline and about the additional insight into literature gained by the adaptation of the scientific concepts. By now one can state that chaos-theoretical literary studies have produced some insights into literature and many into the field of the literary studies. The adaptation of chaos theory by the literary studies can be seen as a gauge of self-reflection and -observation of the discipline. In presenting some similarities as well as differences between chaos theoretically influenced literary studies and the literary studies under the paradigm of constructivism, the author would like to demonstrate the mechanisms of cultural

According to the chaotic features and typical fractional order characteristics of the bearing vibration intensity time series, a forecasting approach based on long range dependence (LRD) is proposed. In order to reveal the internal chaotic properties, vibration intensity time series are reconstructed based on chaos theory in phase-space, the delay time is computed with C-C method and the optimal embedding dimension and saturated correlation dimension are calculated via the Grassberger-Procaccia (G-P) method, respectively, so that the chaotic characteristics of vibration intensity time series can be jointly determined by the largest Lyapunov exponent and phase plane trajectory of vibration intensity time series, meanwhile, the largest Lyapunov exponent is calculated by the Wolf method and phase plane trajectory is illustrated using Duffing-Holmes Oscillator (DHO). The Hurst exponent and long range dependence prediction method are proposed to verify the typical fractional order features and improve the

Entropy explores the concept of entropy and its place in and on the human body. Many of the patterns in Entropy are inspired by medical imagery, primarily enlarged views of cell colonies (particularly those of diseases) reproducing, developing and overtaking their host. I was initially drawn to a series of images revealing close-up views of a variety of diseases. These images are incredibly beautiful, filled with repeating patterns and fractal-like designs. That beauty can be found in something considered so debilitating is a very intriguing juxtaposition. I have since been working with these models to design several pieces of jewelry referencing these patterns. This body of work is an attempt to bring that which lies beneath the skin to the surface, changing the destructive into the beautiful ...

The onset of labour represents the starting point of a perilous challenge in life, as a new born must adapt to an unknown environment. During this adaptation there are several risks: hypoxia, asphyxia, trauma, intervention and, in worst case scenario, death. These risks can be reduced trough electronic fetal monitoring. During this delicate period the study and analysis of the variability in beat-to-beat intervals of fetal heart rate plays a fundamental role in the pursuit of fetal wellbeing, reduction of fetal morbidity and mortality. Given that the use of an animal model allows direct experimental manipulation of the subjects and their environment and considering the ethical issues and difficulties to acquire data related to asphyxia during labour and delivery, linear techniques (time domain and frequency domain) and non-linear techniques (detrended fluctuation analysis, complexity analysis and Poincarè indices and plots) have been initially implemented for the study of heart rate variability ...

N2 - Fractal measures such as fractal dimension (FD) can quantify the structural complexity of the brain. These have been used in clinical neuroscience to investigate brain development, ageing and in studies of psychiatric and neurological disorders. Here, we examined associations between the FD of white matter and cognitive changes across the life course in the absence of detectable brain disease. The FD was calculated from segmented cerebral white matter MR images in 217 subjects aged about 68years, in whom archived intelligence scores from age 11years were available. Cognitive test scores of fluid and crystallised intelligence were obtained at the time of MR imaging. Significant ...

This volume lays a rock-solid foundation for the subjects of long-range dependence and self-similarity. It also provides an up-to-date survey of more specialized topics at the center of this research area. The text is very readable and suitable for graduate courses, as it is self-contained and does not require more than an introductory course on stochastic calculus and time series. It is also written with the necessary level of mathematical detail to make it suitable for self-study. I particularly enjoyed the very nice introduction to fractional Brownian motion, its different representations, its stochastic calculus, and the connection to fractional calculus. I strongly recommend this book, which is a welcome addition to the literature and useful for a large audience. Eric Moulines, Centre de Mathématiques Appliquées, École Polytechnique, Paris. This book provides a modern, rigorous introduction to long-range dependence and self-similarity. The authors write with wonderful clarity, covering ...

A quasilinear analysis of the relativistic electron cyclotron maser instability is presented. A background plasma is assumed to support the wave motion, while the instability is driven by a tenuous population of energetic electrons possessing a loss-cone feature. The analysis makes use of an efBcient moment method. In this approach, evolution equations for the moments of particle distribution function are derived from the particle kinetic equation. Then, a self-similar model of the loss-cone electron distribution function is imposed. Simultaneously, the wave kinetic equation is solved. The resulting fully self-consistent set of equations that governs the evolution of the particles and unstable waves is solved numerically under physical parameters that represent typical solar microwave burst sources ...

Analog superconductive components have been integrated to form a device capable of crosscorrelation between two wideband analog input signals. Arrays of Nb/Nb205/Pb tunnel junctions perform the mixing of delayed samples of two frequency-offset analog signals counterpropagating along a niobium tapped transmission line. The resultant mixer products from the junction array are integrated and stored in a high-Q (ft,' 600) lumped element L-C resonator tuned to the signal difference frequency. A superconductive tunnel junction imbedded in the resonator circuit is operated as a variable-threshold comparator to detect the time-integrated current stored in the resonator. We present results showing the correlation properties of such an individual correlator cell, together with the design and performance of a 4-junction-logic (4JL)-based digital address encoder to be used in a multichannel correlator device. We also discuss the important design issues as they relate to analog signal processing ...

The Center for Theoretical Biological Physics PRESENTS Seminar Speaker Ludmil B. Alexandrov Oppenheimer Fellow Center for Nonlinear Studies Los Alamos National Laboratory Abstract: All cancers are caused by somatic mutations. These mutations may be the consequence of the intrinsic slight infidelity of the DNA replication machinery, exogenous or endogenous mutagen exposures, enzymatic modification of DNA, or defective DNA repair. In some cancer types, a substantial proportion of somatic mutations are known to be generated by exogenous carcinogens, for example, tobacco smoking in lung cancers and ultraviolet light in skin cancers, or by abnormalities of DNA maintenance, for example, defective DNA mismatch repair in some colorectal cancers. Each biological process causing mutations leaves a characteristic imprint on the genome of a cancer cell, termed, mutational signature. In this talk, I will present mutational signatures analyses encompassing 12, 023 cancer genomes across 40 distinct types of ...

Autori: Vlad MO, Morán F, Popa VT, Szedlacsek SE, Ross J.. Editorial: Proc Natl Acad Sci U S A, 104(12), p.4798-803, 2007.. Rezumat:. We give a functional generalization of fractal scaling laws applied to response problems as well as to probability distributions. We consider excitations and responses, which are functions of a given state vector. Based on scaling arguments, we derive a general nonlinear response functional scaling law, which expresses the logarithm of a response at a given state as a superposition of the values of the logarithms of the excitations at different states. Such a functional response law may result from the balance of different growth processes, characterized by variable growth rates, and it is the first order approximation of a perturbation expansion similar to the phase expansion. Our response law is a generalization of the static fractal scaling law and can be applied to the study of various problems from physics, chemistry, and biology. We consider some ...
