The use of appropriate level of theories for studying weak interactions such as 8-8 stackinginteractions of aromatic molecules has been an important aspect, since the high level methods havelimitations for application to large molecules. The differences in the stacking energies of variousaromatic molecular structures are found significant. It is also very important for identifying the mostfavor...

Using efficient methods that reduce the search space, we design an algorithm strong enough to solve all 8×8 Hex openings.

We study the possibility of prediction/decision making in a finite 2-person game with pure strategies, following the Nash-Johansen noncooperative solution theory. We adopt the infinite-regress logic EIR (a fixed-point extension of the epistemic logic KD with 2 persons) to capture individual decision making from the viewpoint of logical inference. In the logic EIR, prediction/decision making is ...

The ribose conformations of 8-azaadenosine, 8-azaguanosine, and 8-azainosine have been studied using proton magnetic resonance in ND3 solutions, in D2O solutions, and in pyridine solutions. The temperature was varied between -60 and +40 degrees C in ND3 and between +10 and +60 degrees C in D20 solutions. The analysis is based on the two state S in equilibrium N model of the ribose moiety propos...
