The cosmological constant problem is explained by a theory based on the discrete space-time hypothesis. The calculated cosmological constant value
Learning and adaptation is a fundamental property of intelligent agents. In the context of adaptive information filtering, a filtering agent's
The small or zero cosmological constant, $Λ$, probably results from a macroscopic cancellation mechanism of the zero-point energies. However, nearby
We summarize constraints on neutron star masses from ongoing timing observations of pulsar-white dwarf binaries at Arecibo. The trend is
A new recursion formula is presented for the correlation functions of the integrable spin 1/2 XXX chain with inhomogeneity. It
We consider a net of *-algebras, locally around any point of observation, equipped with a natural partial order related to
One discusses here the connection between σ-model gauge anomalies and the existence of a connection with torsion that does not
[Talk presented at the International Seminar Quarks `92, Zvenigorod, Russia, May 11-17, 1992.] The electroweak vacuum need not be absolutely
We present an INTEGRAL observation of the Cen-Crux region in order to search the electron cyclotron resonance scattering features from
We present the results of a search for pulsed TeV emission from the Crab pulsar using the Whipple Observatory's 10m
We present an analysis of X-ray observations of the trans-Jovian planets Saturn, Uranus and Neptune with the ROSAT PSPC in
A solution to the generation puzzle based on a nonabelian generalization of electric-magnetic duality is briefly reviewed. It predicts 3
Replacement of cond-mat/0002383. Re-analysis of computer simulations, new figures and modification of conclusions.
The readout process of a superconducting flux-qubit is theoretically analyzed in terms of the quantum dynamics of a qubit-SQUID coupled
We present the design of a ring exchange interaction in cold atomic gases subjected to an optical lattice using well
We have created a dark quantum superposition state of a Rb Bose-Einstein condensate (BEC) and a degenerate gas of Rb$_2$
We have undertaken a photometric study of the SW Sex star, PX And. We clearly identify a negative superhump signal
The systematic investigations of the role of the virtual charm axial currents in the decay of $B$-mesons to $η'$ $K$
We study the interface dynamics of a binary particle mixture in a rotating cylinder numerically. By considering only the particle
A general and systematic construction of Non Abelian affine Toda models and its symmetries is proposed in terms of its
The back reaction of gravitational perturbations in a homogeneous background is determined by an effective energy-momentum tensor quadratic in the
We analyze the conductance distribution function in the one-dimensional Anderson model of localization, for arbitrary energy. For energy at the
This paper has been withdrawn by the authors due to new theoretical evidence and experimental proof that the semiconducting bandgap
Performing an in-depth analysis of the photoemission spectra along the nodal direction of the high temperature superconductor Bi-2212 we have
