High-Efficiency Advanced Audio Coding (HE-AAC) is an audio coding format for lossy data compression of digital audio defined as an MPEG-4 Audio profile in ISO/IEC 14496-3. It is an extension of Low Complexity AAC (AAC LC) optimized for low-bitrate applications such as streaming audio. HE-AAC version 1 profile (HE-AAC v1) uses spectral band replication (SBR) to enhance the compression efficiency in the frequency domain. HE-AAC version 2 profile (HE-AAC v2) couples SBR with Parametric Stereo (PS) to enhance the compression efficiency of stereo signals. It is a standardized and improved version of the AACplus codec.
HE-AAC is used in digital radio standards like DAB+ and Digital Radio Mondiale.
The progenitor of HE-AAC was developed by Coding Technologies under the trade name CT-aacPlus. CT-aacPlus combined MPEG-2 AAC LC with the Coding Technologies invented spectral band replication (SBR). CT-aacPlus is the codec used by XM Radio for their satellite radio service. Subsequently, Coding Technologies submitted their SBR to MPEG as a basis of HE-AAC.
Excitatory amino acid transporters (EAATs), also known as glutamate transporters, belong to the family of neurotransmitter transporters. Glutamate is the principal excitatory neurotransmitter in the vertebrate brain. EAATs serve to terminate the excitatory signal by removal (uptake) of glutamate from the neuronal synaptic cleft into neuroglia and neurons.
The EAATs are membrane-bound secondary transporters that superficially resemble ion channels. These transporters play the important role of regulating concentrations of glutamate in the extracellular space by transporting it along with other ions across cellular membranes. After glutamate is released as the result of an action potential, glutamate transporters quickly remove it from the extracellular space to keep its levels low, thereby terminating the synaptic transmission.
Without the activity of glutamate transporters, glutamate would build up and kill cells in a process called excitotoxicity, in which excessive amounts of glutamate acts as a toxin to neurons by triggering a number of biochemical cascades. The activity of glutamate transporters also allows glutamate to be recycled for repeated release.
Uh, yeah y'know, shit is wild he, heh
Can't complain though I'm alive
Healthy and all a that knahmsayin?
Just tryin' to do my thang, praise to all
Bust it that nigga Slick Rick said, I waited long time sweatin' it
I got jerked but now I'm gettin' it, hazy like asthma bizarre disaster
Stress almost held me down from bein' a master
The faster preacher, poet, a teacher, it's been so long like Monifah
Believe that I'm needed, in rappin', I breathe this
Some pick up a microphone and can't even achieve this
Oscar award winning your shit, I'm bored with it
Stop copy-catting son
(Why?)
'Cause your dog did it
Get your own lingo, make up your own jingle
Ten years later you be bitin' my single
Primo, take it downtown, swing it
Intervenin' on the board, sensimil steamin', yeah
Catch the vibe like a tribal dance
In the clubs on the low with the boy stance
Money rubbin' with a shorty got bumped by a chump
Tell him, step off, I'm doin' the hump, yeah
I say it's my world and I won't stop
And if you stand in my way you bound to get dropped
Some wish that I was gone 'cause they know I'ma win
In a minute, I'll be makin' six G's times ten
I'm the computer, printin' out data take notes
Then analyze the information and press send
Freaky like porno, Ron Jeremy saw no
Obstacle or pussy to stop him from bonin' a hoe
Me and the mic double trouble
Chicks look at us like twins, all lovable and huggable
Prognosis, on the, mic I choke out
Had the same effects from coughin', blowin' smoke out
Architect, rap technician, man listen
It's no doubt you gonna pump this in your system
My skills ill and all of that above
Confidence, I'm not worried 'bout a street buzz
I'm O.C., who you? I never heard of ya
Get out my face 'fore I turn into a motherfuckin' murderer
I want the green like indo, a mansion, a car
A wife who's never been a bimbo
Too much to ask, well, to me that's simple
Wanna retire on a yacht called the S. S. Minnow
I say it's my world and I won't stop
And if you stand in my way, you bound to get dropped
I say it's my world and I won't stop
And if you stand in my way, you bound to get dropped
I say it's my world and I won't stop
And if you stand in my way, you bound to get dropped
I say it's my world and I won't stop
And if you stand in my way, you bound to get dropped
Top choice, this here nigga got poise
Ain't a man alive who could stop my noise
I snatch a star from the sky, spark up your lye
You stand astounded wonderin' how I did it
Now you're star struck, like I truck gold
Treatin' me like a nigga havin' a million records sold
Now a star child, phenomenon like the X-Files
Rappers know I'm comin' so they go in exile
Czar in this rap shit, comin' on your mattress
Microphone fiend, I make beats do back flips
Fear me like genocide, serious
How I do it through your stereo, mysterious
O.C. do demolition, nil competition
Like robot Kong on a destroy mission
A matter of life and death you try to fight for breath
I snatch your heart from a slice through your chest
Who the best from New York to Bogota?
Who got face thinkin' they scare me with a scar, shit?
What I be bringin' is a terrible sight
A performance never again performed on the mic
I say it's my world and I won't stop
And if you stand in my way, you bound to get dropped
I say it's my world and I won't stop
And if you stand in my way, you bound to get dropped
I say it's my world and I won't stop
And if you stand in my way, you bound to get dropped
I say it's my world and I won't stop
And if you stand in my way, you bound to get dropped
