Most standard methods based on maximum likelihood (ML) estimates of power-law exponents can only be reliably used to identify exponents smaller than minus one. The argument that power laws are otherwise not normalizable, depends on the underlying sample space the data is drawn from, and is true only for sample spaces that are unbounded from above. Power-laws obtained from bounded sample spaces ...

The politics of contestation on the part of secondary regional powers such as Argentina, Chile, Colombia and Venezuela towards Brazil as the regional leader oscillate between competition and cooperation, inasmuch as the South American region has one regional power and is a zone of negative peace without aggressive rivalries. The secondary powers use different tactics, which c...

Genetic factors, external stress and the human factor are influential to the health and well-being of every person. Several studies have shown that the human being have many internal powers that can promote health and increase quality of life. A theory on the human meaning of life is put forward and how it relates to health, disease and quality of life in the context of holistic medicine.

Evidence is presented that raises questions about the Clinton administration's policy of promoting peace by promoting democratization. The expectation that the spread of democracy will probably contribute to peace in the long run, once new democracies mature, provides little comfort to those who might face a heightened risk of war in the short run. Pushing nuclear-armed great powers like Russia...

The relative commutant A∩A of a strongly self-absorbing algebra A is indistinguishable from its ultrapower A . This applies both to the case when A is the hyperfinite II1 factor and to the case when it is a strongly self-absorbing C-algebra. In the latter case we prove analogous results for l∞(A)/c0(A) and reduced powers corresponding to other filters on N. Examples of algebras with approximate...

The X = M conjecture of Hatayama et al. asserts the equality between the one-dimensional configuration sum X expressed as the generating function of crystal paths with energy statistics and the fermionic formula M for all affine Kac–Moody algebra. In this paper we prove the X = M conjecture for tensor products of Kirillov–Reshetikhin crystals B1,s associated to symmetric powers for all nonexcep...
