hi..all i have a doubt in coding theory...?
Q. what is the difference between rcpc codes and punctured convolutional codes?? i am implementing RCPC encoder and decoder ( viterbi algorithm)..i am clear so far on encoding, puncturing,depuncturing and viterbi decoding..but how can i bring rate compatibility into picture...? plz answer this...

A. No difference, but rather RCPC is a subset of Punctured Convolutional codes. RCPC codes are a special case of punctured convolutional codes, that have rate compatibility defined by a sequence of puncturing matrices,.

In the endosymbiont theory, WHEN and HOW do mitochondria/chloroplasts begin to be coded into human DNA?
Q. I'm already familiar with most of the theory, but I can't really understand the part where human DNA begins to code for mitochondria of its own. If mitochondria begin as separate organisms, and gradually were incorporated in a symbiotic relationship with eukaryotic cells, HOW do eukaryotic cells begin to be born with DNA that codes for mitochondria to be "grown"? In other words, newborn human cells don't ever have to "pick up" new mitochondria. Basically, HOW DID 2 organisms become one? Thanks!

A. Excellent question!, one that many people fail to consider. The general process by which '2 organisms become one' is symbiogenesis. I will explain the general process by which chloroplasts and mitochondria evolved into what they are today. Because they are so similar in their evolutionary history, I will just describe the process for mitochondria. Mitochondria are thought to have originally evolved from the prokaryotic group of bacteria: proteobacteria. These bacteria were taken up by another cell (whether by phagocytosis or another means). The proteobacteria have their own genetic material which codes for proteins and other molecules that make up the organism. So, the question is how could this nuclear material become incorporated into… [cont.]

Isn't the theory of evolution actually faith-based since it breaks so many known scientific laws?
Q. Isn't evolution a faith based system of thought rather than a credible hypothesis based on scientific laws? Should there not be be millions and millions of intermediate forms in either the fossil record, as well as continuing into mankind's recorded history so that a legitimate scientific inquiry based effort can examine evolution as a potential credible hypothesis, since there would have to be according to the theory of evolution untold millions of adaptations whether failed or successful, at least up until recorded history and there is none? Lets see, not only is there the law of scientific inquiry whereby the laws of evidence should require some significant number of colected data like transitional forms between the myriad classes… [cont.]

A. I completely and wholeheartedly agree with all of this, although i highly doubt that many others will agree. It is truly hypocritical when government funded schools teach evolution, not as a scientific theory, but as a scientific fact, under the guise that teaching any other theory is irrational and unscientific, and thereby false. The first step of the scientific method is observation. Our science needs to be based on observed reality, or else it cannot be proven. Evolution and any other theory regarding origins cannot be proven scientifically because it is not based on observed reality. I'm not here to argue about religion or who's right or wrong. I'm just restating that it takes just as much faith, if not more, to believe in a… [cont.]
