Lewicki [12] demonstrated that efficient coding of natural sounds could provide an explanation for both the form of auditory nerve filtering properties and their organization as a population.
For example, the spatial tuning of cells in both the retina and early visual cortex are well predicted from efficient coding of natural scene statistics, and suggest that vision is optimized for the natural visual environment (Atick, 1990; Field, 1987; Simoncelli & Olshausen, 2001).
The suggested roles of COS in visual encoding have included orientation tuning ([29], [10], [30]), contrast gain control ([31], [32], [11], [33], [34]), and redundancy reduction in the coding of natural images ([35], [36], [37]).
The truth is, according to the Code of Federal Regulations, natural flavoring is "derived" (read processed) from nature for "flavoring rather than nutritional" purposes.
Here we demonstrate that jamming of olfactory perception also occurs naturally, as a part of olfactory coding of complex natural blends.
(An oracle concerning a sequence is a special state in a Turing machine that allows that machine, having computed a string x to obtain a 'yes/no' answer concerning whether the x-th member of the sequence has value 1; equivalently, conceiving of the sequence as coding a set of natural numbers, whether or not x is a member of the set see Li and Vitányi 2008: 38).
On the other hand, a particularly interesting family of non-protein coding RNAs consists of natural antisense transcripts (NATs).
Nothing wrong with this, but it is a label he rails against as there is the sense he believes it is code for accusing him of natural negativity.
The genetic code limits the components of natural proteins, like RNase A, to 20 or so α-amino acids.
Although the genetic code limits the components of natural proteins to 20 or so α-amino acids, NCL and EPL enable the semisynthetic incorporation of a limitless variety of nonnatural modules into proteins.
