great! Thank you very much! Maze, and JBunniii

Not, I don't know. I will study it. Can you give me some hint?

Thanks HallsofIvy. I just want to know whether ATA is symmetric positive definite if A is a N*N matrix, and A is a non-singular matrix.

Suppose A is a non-singular matrix. AT is the transpose matrix of A. Therefore, the eigenvalue of A can be expressed as: S-1AS=Λ (S-1AS)T=ΛT (AS)TS-T=STATS-T=Λ So, AT and A share the same eigenvalue and eigenvector. Here, x is the base eigenvector of A. Hence, span{x} is the eigenvector of...

thx!

who can tell the name of such organism. I want to buy it from agency, but I don't know how to call it! It is very urgent, pls tell me, thx!

what's the relation be zmole (zettamole) and mole? thx!

Hi. Are there someone working on Metallothionein? Maybe we can discuss on something because I am Electronic Engineering Student who work on the Bio-Sensor. Edit: removed e-mail Welcome.!

secondly, I do not think dragging is a good term. If you use resonance, you could have a good comprehension. (In my opinion)

I think the \varpi coordinate should be normalized, if you want to have a good comprehension. When \varpi increase, it can not obey the SPPs but the free gas plasmons dispersion in upper band.

because E=-\nabla\varphi. from upper equation \varphi=C1Z+C2; so E=-C1=E0, it is independence with the position. So, I can said when Z=0 or somewhere z<1/2a, E=E0. by the way, maybe it could be \epsilonE0 because of the continuity at the boundary. So sorry, lots of confusion.

thank you very much! But if I apply the Laplace Equation: curl2φ=0, because φ is independence of x and y. So: φ=C1Z+C2. when Z increase to infinitude. E=-curlφ=-C1 =E0. Suppose the midst of conductor layer is Z=0. when z=0, it always E=E0. But it should be 0, where am I wrong?

A 1-D metal put inside a E0 electric field just like shown in following figure. --> |- <-- +| -->  --> |- <-- +| -->  --> |- <-- +| --> E0 --> |- <-- +| -->  --> |- <-- +| --> Suppose the positive charge density of δ1, the negative charge density δ2, δ1=-δ2...
