Memory Definition and 309 Threads

A review of memory reconsolidation[1], the recent experiment in which memory traces were attenuated[2] and a caveat that recovery of the fear memory is typical in patients [3]. [1] http://www.nature.com/nrn/journal/v8/n4/abs/nrn2090.html [2]...

I have many subroutines which I want to compile individually using makefile. But the memory allocation is not specified in ".INC" file but as separate subroutine depending on the user input. The "gfortran" compiler is showing the following error...

I'm having trouble allocating memory for a dynamic two dimensional array in FORTRAN 90; the odd thing is that when I did the same thing using three on dimensional arrays instead of an array with the dimensions 3*x, I didn't have a problem. read (1,*) ndat1 !The first line of every file is...

My answer is that the 3Gigabits of base 4 memory in the human genome is equivalent to 750MB of binary standardised to 8 bits/byte. Once I have taken into account that there are two copies, evolutionary junk and repeated or copied areas, I am getting an estimate of around 30MB.

Homework Statement Show that the exponential distribution has the memory loss property. Homework Equations f_T(t) = \frac{1}{\beta}e^{-t/\beta} The memory loss property exists if we can show that P(X>s_1+s_2|X>s_1) = P(X>s_2) Where...

I am trying to setup digital control of slow simple peripherals using the UART. I am trying to locate the UART in RAM and it is not working. I have a '486 running windows 3.1.1 and using Microsoft quick basic. This code prints numbers which are supposed to change when the com2 uart sees a...

I want to set the area from with malloc gets its memory to a mmap'ed shared memory file, to share data between children and parents without causing pagefaults. It is safe because the data used by children is guaranteed not to be touched by the parent and the children are guaranteed not to malloc...

A friend of mine is working with shape memory alloys and he's got one that is behaving strangely. At "low" temperatures a "fresh" solution heat treated sample will form martensite upon cooling, and austenite upon heating as expected. Heat and cool all you want and you get the transformation...

What would the first and last address be? I said 0 and 1999 but the answer was 0 and some other number which i don't remember (it wasnt 1999 haha) What is the correct number for the last address and why isn't it 1999 since there are 2000 bytes in a 2k ram?

What are the advantages to having super-fast memory in a computer? I'm talking about RAM with speeds above 2000 MHz and beyond. Does PC gaming benefit from blazing-fast memory?

When I was a child, I picked a iron from the earth. It looks a iron, it has a thin layer rust outside. but the shape looks like a stone. it is about 26mm long. I erase a little rust by knife. then the position will not get rusty afterwards in the room even many years.
