General spherically symmetric solutions of Einstein vacuum field equations with [LAMBDA].
July 1, 2002... A one-parameter family of inequivalent non-static spacetimes for a point mass in the presence of cosmological constant are investigated. Keywords: General Relativity, Exact Solutions, Point Mass, Cosmological Constant. I. Intoduction...

Darboux transformations and isospectral potentials in quantum mechanics.
July 1, 2002... We show that the Darboux transformations allow to construct generalized isospectral potentials for a given standard potential, this in the frame of the Schodinger equation. An application is made for the Hulthen interaction. PACS:...

Role of Earth's rotation in experiments to detect neutrino mass.
July 1, 2002... In the paper it is shown that the influence of the Earth's rotation is a major factor for improving the estimation of neutrino mass. Keywords: (neutrino, Earth's rotation, and cosmology) The lower limit of mass of the electron...

A universe older than itself? (from the cave of the Troglodyte astronomer).(Brief Article)
July 1, 2002... A European Space Agency team found three times more iron in quasar APM 8279+5255 than exists in our solar system today. So what, you say? The catch is that this quasar is roughly 13.5 billion light years away, if its redshift is any...

Anomalous statistics and the rescaling of Planck's-constant.
July 1, 2002... Numerous forms of anomalous particle statistics have been motivated by 2+1 dimensional anayons, the multifractal structure of non-extensive systems, and the possible bosonic-fermionic nature of any fundamental particle. From recent studies in...
