Introduction and summary

What is a Fractal?

 

A fractal is a geometric object (like a line or a circle) which is however rough or irregular on all scales of length, and so which appears to be 'broken up' in a radical way. Some of the best examples can be divided into parts, each of which is similar to the original object. Fractals are said to possess infinite detail, and they may actually have a self-similar structure that occurs at different levels of magnification.  The most well-known fractals are the Mandelbrot Set and Julia Sets. Jules Ruis developed the so called Julius Ruis Set. This is a smart presentation of 400 Julia sets, showing that the Mandelbrot Set is the parameter basin of all closed Julia Sets.

 

Why Fractal Geometry?

 

Fractals provide scientists with a new vocabulary to read the book of nature. Galileo's circles and triangles are insufficient to describe nature in all its rugged complexity. In addition, the fact that natural objects are commonly self-similar, makes fractals ideal models for many of those objects. Fractal geometry also provides scientists with a new way of looking and experimenting with old problems using a different perspective. What is most exciting about fractals is that they successfully bring geometry to where it did not appear to belong, an idea reminiscent of general relativity, which is based on the introduction of geometry to understand the cosmos.

 

What is Fractal Geometry good for?

 

Fractal geometry is a compact way of encoding the enormous complexity of many natural objects. By iterating a relatively simple construction rule, we see how an original simple object can be transformed into an enormously complex one by adding ever increasing detail to it, at the same time preserving affinity between the whole and the parts, or scale invariance. Just think of a big oak tree in winter. Its branches are naked so it is easy to distinguish the way in which a twig splits and becomes two which then split again, to become four; in much the same way in which the trunk first split into slender branches which split again and then again, and again. The self-similarity is evident, the whole looks just like its parts, yet not exactly. Nature has slightly altered the construction rule, introducing some degree of randomness which will make one oak slightly different from any other oak tree in the world.

Now, imagine packing all the information required by the tree to become a beautiful large oak tree into the smallest possible space, with the greatest economy of means. It would appear logical that rather than encoding all the unique, intricate complex branching of a mature oak in its seed (an acorn), all the details of its evolving shape, nature simply encodes the splitting rule, and the urge to repeat it, to iterate. This, plus a little randomness during growth that changes the number of splits or their place in a branch is enough to create a unique oak tree. In fact a whole computer data compression industry is based on similar ideas that permit coding and compressing large files to be quickly transmitted through the Internet.

 

 

Patent application

 

Jules Ruis, managing director of Fractal Consultancy (The Netherlands), filed end 2006 a patent application on a procedure using fractal geometry for the design and manufacturing of artificial human and/or animal organs, more specifically human blood vessels. The designed structures can be presented in a two-dimensional as well as a three-dimensional way.

The patent pending also emphasizes the use of fractal geometry for the direction of print- and injectionheads in equipment used for the application of materials (inkjet printing and methods of direct writing), and equipment that directs laserbeams and electronic beams (electron microscopes).

Fractal Geometry

 

-          Fractal Geometry is the iteration of complex functions like (inverted) polynomials (z2, z3, etc) and complex (inverted) transcendental functions  (sin(z), cos(z), tan(z), exp(z) ).

-          A complex number has the form

z=x + i*y or c=a + i*b with i2 =-1

-          In fractal formulas zn+1 means z(new) and zn means z(old).

-          Formula in  function is iterated from 1 to maximal ‘k’ times.

-          Iteration goes on until predeter-mined small/great value has been reached (function is going to zero or infinity).

-          Quantity of real done iterations is called ‘f’ (‘flightnumber’).

-          Instruction at the end of the procedure, coupled on reached ‘f’, is : pset color, position machine printhead (ink, matter, cell or molecule, etc), manipulate beam/bundle or position motor.

-          Calculate next computer-pixel and manipulate next machine-voxel, layer for layer.

 

Fractal Imaginator

 

-          The Fractal Imaginator is a software program to create fractals.

-          Using the program Fi you can input your own mathematical formulas and other relevant data.

-          The created images are saved as bmp/jpg/png files or obj/stl/pov files.

-          The parameters of the image are stored in separated data-files (.fim files).

-          This way of storing saves much computer capacity.

Fractals support growing organs

Today scientists can regenerate tissue such as skin, but they are still figuring out how to grow replacement organs. The challenge is in coaxing cells from organs to grow into new organs rather than unstructured clusters of cells.

Researchers found a way to impart structure to growing cells that may eventually allow for growth of entire organs.

 

If the method proves successful, "we can use [a] patient's own cells to create a living organ and this will remove the problems with organ rejections" and a shortage of donor organs, said Mohammed Kaazempur-Mofrad, a researcher at MIT


Key to the method is supporting the growing cells with something akin to the circulatory system, which provides cells with oxygen and nutrients. "In order to make living replacements for large vital organs such as the liver and kidney, it is essential to integrate the creation of vasculature with the tissue engineering," said Kaazempur-Mofrad. And the growth of these vascular networks has to be highly controlled and precise, he said.

 

The researchers used computer-generated fractal patterns to fabricate a network of branching, microscopic tubes. Fractals are patterns that repeat at different scales. If, for instance, one portion of a fractal looks like a tree, zooming in on its branches and twigs will show that they also look like trees, and zooming further will show that their branches and twigs follow the same pattern.

These self-similar patterns are common in nature, including natural blood vessel networks, and can scale up or down in size. "Using [the] fractal concept will make it easier to mimic... nature and also to scale up our designs from one animal to another," said Kaazempur-Mofrad.

Print me a heart and a set of arteries (publication d.d. April 2006)

www.fractal.org/Fractal-Research-and-Products/Print-arteries.mht

Sitting in a culture dish, a layer of chicken heart cells beats in synchrony. But this muscle layer was not sliced from an intact heart, nor even grown laboriously in the lab. Instead, it was "printed", using a technology that could be the future of tissue engineering.

Gabor Forgacs, a biophysicist at the University of Missouri in Columbia, described his "bioprinting" technique last week at the Experimental Biology 2006 meeting in San Francisco. It relies on droplets of "bioink", clumps of cells a few hundred micrometres in diameter, which Forgacs has found behave just like a liquid.

This means that droplets placed next to one another will flow together and fuse, forming layers, rings or other shapes, depending on how they were deposited. To print 3D structures, Forgacs and his colleagues alternate layers of supporting gel, dubbed "biopaper", with the bioink droplets. To build tubes that could serve as blood vessels, for instance, they lay down successive rings containing muscle and endothelial cells, which line our arteries and veins. "We can print any desired structure, in principle," Forgacs told the meeting.

Other tissue engineers have tried printing 3D structures, using modified ink-jet printers which spray cells suspended in liquid (New Scientist, 25 January 2003, p 16). Now Forgacs and a company called Sciperio have developed a device with printing heads that extrude clumps of cells mechanically so that they emerge one by one from a micropipette. This results in a higher density of cells in the final printed structure, meaning that an authentic tissue structure can be created faster.

Cells seem to survive the printing process well. When layers of chicken heart cells were printed they quickly begin behaving as they would in a real organ. "After 19 hours or so, the whole structure starts to beat in a synchronous manner," says Forgacs.

Most tissue engineers trying to build 3D structures start with a scaffold of the desired shape, which they seed with cells and grow for weeks in the lab. This is how Anthony Atala of Wake Forest University in Winston-Salem, North Carolina, and his colleagues grew the bladders which he successfully implanted into seven people (New Scientist, 8 April 2006, p 10). But if tissue engineering goes mainstream, faster and cheaper methods will be a boon. "Bioprinting is the way to go," says Vladimir Mironov, a tissue engineer at the Medical University of South Carolina in Charleston.

-          An ovum is a female reproductive cell. This cell is the largest cell in human body.

-          The middle image is a fractal made of tan(z) on the position a=0 and b=3,298575

-          The exp(z) gives also a repeated pattern on the y-axis on multiplied positions of  1/10 pi (0,31415)

Ovum (egg cell)

Julia: zn+1 = c * tan (zn)

-          The human cell consists of a nucleus embedded in cytoplasm and surrounded by a membrane.

-          Different  organelles are driving in the cytoplasm. e.g. the mitochondria that are the ‘power factories’ of the cell.

-          The fractal formula for the middle image is a polynomial divided by another polynomial.

-          Neurons (also known as nerve cells) are electrically excitable cells in the nervous system that process and transmit information.

-          Neurons are typically composed of a soma, or cell body, a dendritic tree and an axon.

-          The fractal formula is of the form ‘if-then-else’ composed with sin(n)+1 and sin(n)-1.

-          Mitochondria are complex organelles that convert energy from food into a form that the cell can use. They have their own genetic material, separate from the DNA in the nucleus.

-          Analysis of the mtDNA (about 16.000 base-pairs of nucleotides) let us see that the mtDNA is fractal structured.

-          Bacteria are prokaryotes. Unlike animals and other eukaryotes, bacterial cells do not contain a nucleus or other membrane-bound organelles.

-          It has many shapes including spheres, rods, and spirals.

-          The fractal formula is a special composition of cos(n) multiplied with a polynomial.

Bacterium

-          A virus can infect the cells of a biological organism. They cannot reproduce on their own.

-          Their surface carries specific tools designed to cross the barriers of their host cells.

-          The fractal formula for the virus and the bacterium is the same.

-          Zooming in and out creates the difference.

Andras Pellionisz (International PostGenetics Society):

“My knowledge of the universe is almost nil; 40+ years of research and 3 Ph.D.-s in Computer Engineering, Biology, and Physics don't measure up to the universe. However, having devoted the most recent 7 years entirely to the deep study of the DNA, I have evidence that the DNA is fractal. Perhaps not surprisingly, since it is a rather conspicuous tiny part of the universe.”

-          DNA is a double helix formed by base pairs attached to a sugar-phosphate backbone.

-          DNA can also be found in the mitochondria. This mtDNA is fractal structured.

-          A molecule is a group of atoms in a definite arrangement held together by chemical bonds.

-          Scientists  have created and captured a man-made molecule at the nanoscale.

-          It shows a fractal structure.

-          The geometric fractal was made with a formula for the inverted polynomial z^-6

-          Atoms are the building blocks of the molecules.

-          Each atom consists out of a nucleus with protons and neutrons.

-          Electrons are moving in 8 orbits around the nucleus.

-          See Periodic Chart of Elements:

-          There are 2 types of  subatomic elements: fermions which make matter and bosons which make forces.

-          Each element is as well particle as wave, depending of the eye of the beholder.

-          The fractal orbits of z^6 can be influenced by the external ‘flightnumber’ going to infinity.

Subatomic particles

-          Unparticles, but not particles, can fit in a theory that has the property of continuous scale-invariance, which is to visualize by fractal images (iterating complex functions).

-          A fractal like this Koch Curve is an example of discrete scale-invariance because it looks the same if multiplied by a fixed number.

Unparticles

The quadratic iteration of the Mandelbrot set [King] compared with the interactive effects of inverse quadratic charge interaction in tissues [Campbell]. Although their genesis arises from differing non-linear process, iteration on the one hand and interaction on the other, the multi-fractal structures of tissues have features similar to the Mandelbrot set on changes of scale. These fractal effects reach from the molecular (a) in which individual proteins are illustrated embedded in the lipid membrane, through cell organelles (b) to the intercellular structure of whole organs as illustrated by skin (c). Such scale-dependent coherence of structure is possible only because of the highly nonlinear nature of the electromagnetic force in quantum charge interactions of fermionic matter.
