A Random Smattering of Stuff
OK, so everything in here will not pass Verifiability, likely to be loaded with misspellings, and is very probably dangerous to your health as an editor. In other words, it is a bunch of junk not to be used anywhere known to computer-, man-, or woman-kind. On the other hand, please enjoy my privacy as I try to develop just one single sentence that might be usable somewhere in a future time and place. Bridgettttttte babblepoop 12:08, 23 June 2010 (UTC)

1) Is the counter correct? 35,000 hits on this thing: http://www.kcfs.org/forums/viewtopic.php?t=870&highlight=youvan ?

2) How to write this in a wiki compatible form:

alpha=4;word=3;dict=.;

dict=Partition[Flatten[Tuples[Reverse[IdentityMatrix[alpha]],word]],(alpha*word)]

PseudoInverse[dict]==((Transpose[dict])*((alpha)^-(word -1)))-((word - 1)/(alpha^word)/word)

3) Darwin insults women: His attitude toward women colored his scientific insights. "The female is less eager than the male," he wrote, "She is coy," and when she takes part in choosing a mate, she chooses "not the male which is most attractive to her, but the one which is least distasteful." http://www.crystalinks.com/darwin.html


 * Chuck, That is inconsistent with my ability to make your babies survive via my DDD's!

4) Hilarious to a mathematical physicist ??? "Ignorance more frequently begets confidence than does knowledge: it is those who know little, not those who know much, who so positively assert that this or that problem will never be solved by science." First quote on http://www.darwin-literature.com/l_quotes.html .  Try www.weather.com about 10 days out! Or try: http://www.claymath.org/millennium/P_vs_NP/ if P=NP is required as the underlying math for a physical or biological description of a mechanism.

I just lost about an hour of editing here, and there is nothing in history for UNDO

5) Troublesome quote: Martinus J. G. Veltman, the 1999 Nobel laureate in physics, suggested the prize "bridg[ed] the gap between sense and nonsense". from http://en.wikipedia.org/wiki/Templeton_Prize

Set PI Equation
Checking editor Algebraist for how he parsed all the nesting by seperating out all the 's:


 * dict=Partition[Flatten[Tuples[Reverse[IdentityMatrix[alpha]],word]],(alpha*word)]
 * PseudoInverse[dict]=((Transpose[dict])*((alpha)^-(word -1))) - ((word - 1)/(alpha^word)/word)


 * First 8 left and then 8 right parenthesis:


 * 12Transpose[dict])*34alpha)^-5word -1)))-67word - 1)/8alpha^word)/word)
 * ((Transpose[dict]1*((alpha2^-(word -1345-((word - 16/(alpha^word7/word8

PseudoInverse[dict]=


 * ((Transpose[dict])* ((alpha)^-(word -1)) ) - ((word - 1)/(alpha^word)/word)
 * ((Transpose[dict])*((alpha)^-(word -1))) - ((word - 1)/(alpha^word)/word)
 * ((Transpose[dict])*((alpha)^-(word -1))) - ( (word - 1) / (alpha^word) /word)
 * ((Transpose[dict])*((alpha)^-(word -1))) - ((word - 1)/(alpha^word)/word)


 * Your code ((Transpose[dict])*((alpha)^-(word -1)))-((word - 1)/(alpha^word)/word) seems to mean (replacing dict with d and word with w for brevity) $$d^{\mathrm{T}}\alpha^{-(w-1)}-\frac{\frac{w-1}{\alpha^w}}{w}$$. I don't know what most of the functions in your first example are supposed to do, so I can't really interpret that one. But yes, if you want to typeset mathematics properly (on Wikipedia or elsewhere), you should learn some variety of TeX. Algebraist 12:31, 26 June 2010 (UTC)


 * $$d^{\mathrm{T}}\alpha^{-(w-1)}-\frac{\frac{w-1}{\alpha^w}}{w}$$.


 * Algebraist correctly parsed, equation correct, so now add coded side:


 * PseudoInverse[dict]=$$d^{\mathrm{T}}\alpha^{-(w-1)}-\frac{\frac{w-1}{\alpha^w}}{w}$$


 * and now substitute "dict":


 * PseudoInverse[Partition[Flatten[Tuples[Reverse[IdentityMatrix[alpha]],word]],(alpha*word)]] =  $$d^{\mathrm{T}}\alpha^{-(w-1)}-\frac{\frac{w-1}{\alpha^w}}{w}$$


 * go back to "a" for alphabet and "w" for word:

PseudoInverse[Partition[Flatten[Tuples[Reverse[IdentityMatrix[a]],w]],(a*w)]] =  $$d^{\mathrm{T}}a^{-(w-1)}-\frac{\frac{w-1}{a^w}}{w}$$

or, for brevity, terming "dict" as "D" and maintaing definition of D as a seperate equation:


 * PseudoInverse[D] = $$D^{\mathrm{T}}a^{-(w-1)}-\frac{\frac{w-1}{a^w}}{w}$$


 * where, D = Partition[Flatten[Tuples[Reverse[IdentityMatrix[a]],w]],(a*w)]


 * As you see from above, I had to work through this myself to understand what Youvan is saying:


 * Youvan finds that taking the SVD PseudoInverse of a special class of matrices (defined as scroll matrices, D, where w is the word length and a is the alphabet size) scales very poorly in computation time as a and w increase in size, whereas a simpler solution involving scaling factors can be used directly on the transpose of the scroll matrix in rapid computation time to determine the PseudoInverse of these matrices.


 * "Standard practice for displaying variable names in HTML is to use italics. It looks nicer, and it goes better with the png display of TeX. As for the lineheight problem, the obvious solution is to TeX the whole thing, rather than just the right-hand side of it. Algebraist 21:07, 29 June 2010 (UTC) "


 * I've tried to hack line height in MS Word. Looks OK, but it will become a graphic rather than TeX.  That's probably not good for searches. TeX is too much for me to learn.  I need a buddy, college-level, local friend!  Bridgettttttte babblepoop 11:06, 12 September 2010 (UTC)

USDA Rural Energy Funding
I need to remember this date. A few days ago I saw the USDA was doing some funding on this topic at $3M, total, USA national scope. Seems like the wrong total dollars. Announcement was a few days ago and deadline is in less than a month. Sometime in the future maybe I should edit news articles into wiki to see what they funded and cite the program. The newspaper was small town. Maybe they got it wrong. Bridgettttttte babblepoop 11:02, 12 September 2010 (UTC)

Global Economic Equalization
It would be interesting to look up articles to cite in a wiki article on the cost of labor in poorer Asian countries versus the West to see how many man-years of labor is required to buy, for example, an automobile. Let's say it is 10 years for the poor and 1 year for the richer countries. A weighted average might be 5 years. I wonder if any economists have projected that a global equalization will make the "poor richer" and the "rich poorer", contrary to the idiom that the "rich get richer". Such economists might cite labor moving to the poorer with loss of jobs for the richer. Eventually this equalizes, with labor split among nations with an equalization of employment and salaries worldwide. I think the price of fuel has already done this. I doubt that there are ten-fold differences in the price of a gallon of gasoline across all nations. At the same time, I would think there are currently ten-fold differences between Asian auto workers and Detroit auto workers in salary. I wonder if someone has attempted an equation that factors in labor costs to project changes in national standards of living. Bridgettttttte babblepoop 12:12, 12 September 2010 (UTC)

Set Youvan FRET Equations
In spectral analysis algorithms, we use the following notation:

where X can be substituted by 'D', 'A', or 'F' to indicate an image pixel from one of the monochrome fluorescence images acquired through the Donor, Acceptor or FRET channels. The subscript 'u', can be substituted by 'd', 'a' or 'f' to represent a pixel from either a donor, acceptor or FRET bead in the image. The superscript 'y', in the equations below, is replaced by 'b' to indicate that the monochrome image has been background subtracted. We can now write the following ratios:

These ratios are essentially the fractional ‘bleed’ of donor and acceptor, respectively, into the FRET channel. They are then used to correct the FRET channel pixel intensities. The pixel in the corrected FRET image (F c) is given by:
