The byte order mark (BOM) is a Unicode character, U+FEFF BYTE ORDER MARK (BOM), whose appearance as a magic number at the start of a text stream can signal several things to a program consuming the text:
BOM use is optional, and, if used, should appear at the start of the text stream.
Unicode can be encoded as 8-bit, 16-bit, or 32-bit integers. For the 16- and 32-bit representations, a computer receiving text from arbitrary sources needs to know which byte order the integers are encoded in. Because the BOM itself is encoded in the same scheme as the rest of the document, but has a known value, the consumer of the text can examine these first few bytes to determine the encoding. The BOM thus gives the producer of the text a way to describe the text stream's endianness to the consumer of the text without requiring some contract or metadata outside of the text stream itself.
FEFF8 is self-consistent real space multiple-scattering code for simultaneous calculations of x-ray-absorption spectra and electronic structure. Output includes extended x-ray-absorption fine structure (EXAFS), full multiple scattering calculations of various x-ray absorption spectra (XAS) and projected local densities of states (LDOS). The spectra include x-ray absorption near edge structure (XANES), x-ray natural circular dichroism (XNCD), and non-resonant x-ray emission spectra. Calculations of the x-ray scattering amplitude (Thomson and anomalous parts) and spin dependent calculations of x-ray magnetic circular dichroism (XMCD) and spin polarized x-ray absorption spectra (SPXAS and SPEXAFS) are also possible, but less automated.
FEFF8 is used as external program to calculate basic spectra for XANES fitting using FitIt.
Atomic scattering amplitudes and phase shifts are used for EXAFS fitting in IFEFFIT program suite.
How 'bout an ovation
For all the endings in your life
What an occasion
Top stop the bleeding in your mind
My mentor, such deep depression's hard to break
Can't savor in sorrow.
Waiting for a brilliant and illustrious return...
What can ya say for your life?
What are you gonna say, what are you gonna say?
How 'bout a vacation
From all the issues in the way
I'm feelin' elation
For all that's possible
Today will suffer
Will you be leaving us again?
Won't see you tomorrow
Content to make them wonder...
Waiting here resilient while the time has burnt your hands
What can ya say for your life?
What are you gonna say, what are you gonna say?
Broaden the health of your mind
And reflect on your history
Piling on years of reclusive behavior and mystery
Empty today
What can ya say for your life?
What are you gonna say, what are you gonna say?
