We apply correlation analysis of chemical bonds (CACB) to simple organic reaction paths. CACB, an operatorbased formalism for analyzing the electronic structure for molecule, clarifies how bond exchange processes relate to changes in covalent bond orders and bond interaction coefficients. For single bond-exchange processes, the bonds correlation typically is negative for interchanging bonds. Fo...

We propose a new simple scheme for self-interaction correction (SIC) of exchange functionals in the density functional theory. In the new scheme, exchange energies are corrected by substituting exchange self-interactions for exchange functionals in regions of self-interaction. To classify the regions of self-interaction, we take advantage of the property of the total kinetic energy density appr...

The Policy Research Working Paper Series disseminates the findings of work in progress to encourage the exchange of ideas about development issues. An objective of the series is to get the findings out quickly, even if the presentations are less than fully polished. The papers carry the names of the authors and should be cited accordingly. The findings, interpretations, and conclusions expresse...

During ATP hydrolysis by Ca2+-activated chemically skinned fibers from the flight muscle of the giant waterbug Lethocerus indicus, there is extensive phosphate-water oxygen exchange. For unstrained fibers the pattern of exchange shows that there is more than one pathway for hydrolysis, due to the ATPase activity of cross-bridges. Multiple pathways are an established property of both vertebrate ...

This work studies how goal-directed agents can form profitable coalitions. A coalition is formed when some agents agree to cooperate for the achievement of a shared goal or to exchange with each other the achievement of their own goals. Assuming that coalition formation processes are supported by unanimous and enforced agreements, we define two qualitative criteria: the do-ut-des property and t...

Commitments to take or refrain from taking certain actions are indispensable elements in most forms of interaction and exchange. Even the purest form of spot-market transaction rests on commitments: the commitment of the state to value a piece of paper in future exchanges, and the commitment of the individual not to steal back what has been sold. As transactions spread out over time and become ...

Tachyonic Kaluza-Klein modes normally appear from the compactification of extra timelike dimensions with scale L and lead to some instabilities of physical systems. We calculate the contribution of tachyonic gravitons to the self energies of spherical massive bodies of radius R and discuss their possible gravitational stability. We find that some spherical bodies can be stable at critical radii...

Identity-based encryption is a very convenient tool to avoid key management. Recipient-privacy is also a major concern nowadays. To combine both, anonymous identity-based encryption has been proposed. This paper extends this notion to stronger adversaries (the authority itself). We discuss this new notion, together with a new kind of non-malleability with respect to the identity, for several ex...
