Cellular Cognition: Sequential Logic in a Giant Protist

Giant Deep-Sea Protist Produces Bilaterian-like Traces

One of the strongest paleontological arguments in favor of the origin of bilaterally symmetrical animals (Bilateria) prior to their obvious and explosive appearance in the fossil record in the early Cambrian, 542 million years ago, is the occurrence of trace fossils shaped like elongated sinuous grooves or furrows in the Precambrian. Being restricted to the seafloor surface, these traces are re...

Logic, Randomness and Cognition

Many natural intensional properties in artiicial and natural languages are hard to compute. We show that randomized algorithms are often necessary to have good estimators of natural properties and to verify some speciic relations. We concentrate on the reliability of queries to show the advantage of randomized algorithms in uncertain cognitive worlds.

Sequential operators in computability logic

Computability logic (CL) is a semantical platform and research program for redeveloping logic as a formal theory of computability, as opposed to the formal theory of truth which it has more traditionally been. Formulas in CL stand for (interactive) computational problems, understood as games between a machine and its environment; logical operators represent operations on such entities; and “tru...

Sequential Logic Notes

Digital logic circuits composed of components such as AND, OR and NOT gates and that do not contain loops are what we refer to as stateless. In other words, the output that the circuit produces only depends on the current inputs, and does not depend on any previous inputs. These types of circuits are also referred to as combinatorial circuits. However, as we design computing systems, we have a ...
