Initially, this approach was used for parametric optimization of simple bipolar and MOS circuits, e.g. current mirrors, gain stages, differential amplifiers, etc. Encouraged by these results, it was applied to much more complex blocks, such as op-amps.
By modifying the polymer architecture from simple (linear, branched) to more complex types (block, star, comb), and by changing the comonomer compositions, the molecular weights, and polydispersities via conventional or controlled free radical polymerization, PAMA polymers have been developed for a wide variety of applications.
The basic result of this combinatorial evolution is that more and more complex computational blocks (indicated as XOR, EQUIV, IMPLY, etc).
By substituting more robust "shape descriptors" into these schemes we extend their applicability to structures formed from more complex building blocks.
However, the flexibility of this model allows for easy implementation of more complex building blocks such as Maxwell elements, given valid, experimentally derived element parameters.
These objects, however, are more complex building blocks than spheres decorated with symmetrically arranged interaction sites.
The central part of the book then proceeds to cover individual invasive procedures, ranging from trigger point injections through to the more complex neurolytic blocks and intrathecal infusions.
Regexps are easy to teach with games, since each "operator" in a regular expression blocks or matches a different set of characters, so you can easily make tower-defence style games where the player has to construct progressively more complex regexps to block the incoming monsters – there are tons of regexp games online already.
As more complex molecular building blocks for multiple applications become available, there is a need to understand and quantify chemical handles on how to manipulate surface reactions in such a way that highly selective processes would take place.
