A general model of problem-solving processes based on misconception elimination is presented to simulate both impasses and solving processes. The model operates an goal-related rules ond a set of constraint rules in the farm of “IF (state or goal), DO NOT (Action)” for the explicit constraints in the instructions and the implicit constraints that come from misconceptions of legal moves. When im...

The Paris-Harrington Theorem

In Ramsey theory, very large numbers and fast-growing functions are more of a rule than an exception. The classical Ramsey numbers R(n,m) are known to be of exponential size: the original proof directly gives the upper bound R(n,m) ≤ ( m+n−2 n−1 ) , and an exponential lower bound is also known. For the van der Waerden numbers, the original proof produced upper bounds that were not even primitiv...

Stanford scientists have developed a fluorescence imaging technique that allows them to view the pulsing blood vessels of living animals with unprecedented clarity. compared with conventional imaging techniques, the increase in sharpness is akin to wiping fog off your glasses. the technique, called near infrared-2 imaging, or nir-2, involves first injecting water-soluble carbon nanotubes into t...
