New Logical Blend Operations?!

I noticed that the following showed up:

 LogicalClear    Logical operation: Clear (0) DX11.1 only.
 LogicalSet    Logical operation: Set (1) DX11.1 only.
 LogicalCopy    Logical operation: Copy (s) DX11.1 only.
 LogicalCopyInverted    Logical operation: Copy inverted (!s) DX11.1 only.
 LogicalNoop    Logical operation: Noop (d) DX11.1 only.
 LogicalInvert    Logical operation: Invert (!d) DX11.1 only.
 LogicalAnd    Logical operation: And (s & d) DX11.1 only.
 LogicalNand    Logical operation: Nand !(s & d) DX11.1 only.
 LogicalOr    Logical operation: Or (s | d) DX11.1 only.
 LogicalNor    Logical operation: Nor !(s | d) DX11.1 only.
 LogicalXor    Logical operation: Xor (s ^ d) DX11.1 only.
 LogicalEquiv    Logical operation: Equivalence !(s ^ d) DX11.1 only.
 LogicalAndReverse    Logical operation: Reverse And (s & !d) DX11.1 only.
 LogicalAndInverted    Logical operation: Inverted And (!s & d) DX11.1 only.
 LogicalOrReverse    Logical operation: Reverse Or (s | !d) DX11.1 only.

What's the Syntax like to use these bad boys?
