Cell is a multi-core microprocessor microarchitecture that combines a general-purpose PowerPC core of modest performance with streamlined coprocessing elements which greatly accelerate multimedia and vector processing applications, as well as many other forms of dedicated computation.It was developed by Sony, Toshiba, and IBM, an alliance known as "STI". The architectural design and first implementation were carried out at the STI Design Center in Austin, Texas over a four-year period beginning March 2001 on a budget reported by Sony as approaching US$400 million. Cell is shorthand for Cell Broadband Engine Architecture, commonly abbreviated CBEA in full or Cell BE in part.
The first major commercial application of Cell was in Sony's PlayStation 3 game console, released in 2006. In May 2008, the Cell-based IBM Roadrunner supercomputer became the first TOP500 LINPACK sustained 1.0 petaflops system. Mercury Computer Systems also developed designs based on the Cell.
The Cell architecture includes a memory coherence architecture that emphasizes power efficiency, prioritizes bandwidth over low latency, and favors peak computational throughput over simplicity of program code. For these reasons, Cell is widely regarded as a challenging environment for software development. IBM provides a Linux-based development platform to help developers program for Cell chips.
Has anyone experimented with this? Take 2 stem cells. Take the DNA portion out of the one cell and place it inside the second cell. using the same method that the cloning stuff does it.
Or would this method basically just cause mitosis to separate the cells anyway. or would it just kill the...
Hello all,
I am reading some primary literature in which they talk about cell adhesion and cell detachment. They describe different assays for each. My question is, how are these two different? It seems that high detachment is the same as low adhesion, but according to the article, for a...
You are accostumating me bad. I never find good sites for what I am looking for and you always find. This time I am looking for the various theories about the structure of the cell membrane till the fluid mosaic. Thank you one more time. :biggrin:

its supposed to be an urban legend that you can cook an egg with your cellphone. the same way that a microwave cooks an egg but a lot slower because of the power difference, 1500 to 3 (watts).
i was wondering if the cell phone frequency was even high enough to be caught by...

NEED HELP! what is the difference between a fat cell and a lipid?¿?
lipids are said to be molecules!
so why are they also called fat cells. cells are only cells when there is cytoplasm, a cell wall, one or more nuclei, and various organelles, all surrounded by a semipermeable cell...
Ok so at what point do you draw the line when it comes to children having full blown full featured unmonitored cell phones?
Personally, I'd make cell phones equivalent to alcohol. You'd need to be 21 to own one, excessive use in public would be an arrestable offense, and giving a cell phone to...

The membrane of a cell is electrically equivalent to a parallel plate capacitor. A typical cell has a spherical shape with a radius 10 μm and it has a potential of −60 mV with respect to outside. The thickness of the membrane is about 0.01 μm, and it has a dielectric constant of 2.

After having a cell phone for about 3 years, I have realized that I am sick of them. I hate having to take calls and talking to people. If I'm not home, what makes people think I want to talk? All talking should happen in-home with a big handlebar up to your ear and a cord running...
So how effective are these beads? Which dimensions would be optimal for radiation blockage?
I'm understanding that the article assumes that radiation from the cellphone itself would appear to be reduced because the user has a headset and so the phone would be distant from the body. So the...
I am working on trying to get a reliable power supply primarily for my Electrolytic Cell, and secondly for any other power supply needs that should come up.

why is that? i have been told that foetus has haemoglobin gamma not beta and therefore can't...
The hydrogen liberated at the cathode would coat the electrode so polarises the cell. And manganse (IV) oxide is used as a depolariser. I got an equation in my notes:
2MnO2 + 3H2 --> 2MHO(OH) + 2H2O.
But evidently the oxygen doesn't balance.
I tried looking on the internet but still no...
1. I have to calculate the voltage of a standard cell with the following half-cell reactions:

I am trying to understand the chemistry cell thoroughly.
1.If there is only a copper wire connected to a multimeter, there should be no voltage, isn't it?
2. For the set up of a zinc electrode and a copper electrode, will I get a larger voltage by changing the electrode? Such as a more...
I'm going to turn 17 soon, the legal age at which one can donate blood in my state, and I plan on donating blood soon thereafter. Being that I've never done it before, and I'm not tremendously active (thus don't have a particularly strong heart, thus figure that losing a relatively small amount...
What changes would have to be made to a cell
so that when it divides the genes in the daughter cells
are exactly the same,in the same order and number on the chromosomes,
as they were in the parent cell?
Hey guys
For those who have seen HHGG, that sweet white Nokia cellphone that Arthur Dent has, does it exist? If so, does anyone know the model #?

by making the cell membrane too permeable

needed to do this?

Which of the following types of cells would you expect to contain a high density of cytoplasmic intermediate filaments?

This is a 'why' question:
When my phone (GSM, Tmobile in the US) is sitting next to my monitor, or by my radio in my room and is about to receive a call/msg, and while sending a call/msg I get a lot of interference on my radio and monitor. But as soon as the call is in progress, the...
I have a problem that in my physics textbook, a source of EMF is just shown as a box having + and - terminals. The inner workings of that box need not be considered. They claim that although there is obviously an electrostatic force Fe due to this separation of charge, it is countered by a force...
This is something that I have been thinking about lately. :rolleyes: I wanted to address it from a biological view, not a political one. Stem cell research is very contraversial, not only in the political world, but the biological one as well. I was curious as to what everyone here had to say...
How many biologists recognize that the cell is a biochemical computer with molecular memory? I don't mean it is similar to a computer or analogous to a computer. The cell is one design that might be chosen by someone building a molecular level self replicating computer, particularly for...
