Modules with n-acc and the acc on certain types of annihilators

On ACC and Threshold Circuits

We prove that any language in ACC can be approximately computed by two-level circuits of size 2('Ogn)', with a symmetric-function gate at the top and only AND gates on the first level. This implies that any language in ACC can be recognized by depth-3 threshold circuits of size 2('"gn)'. This result gives the first nontrivial upper bound on the computing power of ACC circuits.

Reverse mathematics and the ACC

On the Complexity of Quantum ACC

For any q > 1, let MODq be a quantum gate that determines if the number of 1’s in the input is divisible by q. We show that for any q, t > 1, MODq is equivalent to MODt (up to constant depth). Based on the case q = 2, Moore [8] has shown that quantum analogs of AC(0), ACC[q], and ACC, denoted QAC (0) wf , QACC[2], QACC respectively, define the same class of operators, leaving q > 2 as an open q...

Pain in the ACC?

Lieberman and Eisenberger (1) claim that the “dorsal anterior cingulate cortex (dACC) is selective for pain.” This surprising conclusion contradicts a large body of evidence showing robust dACC responses to nonpainful conditions. Electrophysiological and optogenetic studies have identified neuronal populations activated during foraging behavior, attention, emotion, reward expectancy, skeletomot...
