We review the history of comparisons between bottom production measurements and QCD predictions. We challenge the existence of a `significant
WWW has a scale-free structure where novel information is often difficult to locate. Moreover, Intelligent agents easily get trapped in
The role of the identification of the vacuum and non-vacuum space-times in the computation of vacuum fluctuations in the presence
We numerically analyse the evolution of the flavor non-singlet $g_{1}$ structure function taking into account the all-order resummation of $Ξ±_{s}
We give the results of an analysis of some 18 rise-time calibrations which are based on data collected in 1996/97.
Two sides of cosmological constant problem are discussed: a mysterious compensation of all contributions to vacuum energy with the accuracy
We analyze the evolution of political organizations using a model in which agents change their opinions via two competing mechanisms.
The rise in the use of the arXiv preprint server (astro-ph) over the past decade has led to a major
We propose a simple model of the evolution of a social network which involves local search and volatility (random decay
The essay consists of three parts. In the first part, it is explained how theory of algorithms and computations evaluates
We have made new abundance determinations for a sample of NaMgAl stars. These stars, which are a subgroup of the
The coherent rise and fall of the quasar population is discussed in terms of gas accretion onto massive black holes,
The rise in temperature from the adiabatic compression of a bubble is computed in thermodynamic mean field (van der Waals)
The time evolution of the spectral index and the non-thermal flux in 24 impulsive solar hard X-ray flares of GOES
Time correlated fluctuations interacting with a spatial asymmetry potential are sufficient conditions to give rise to transport of Brownian particles.
An astrophysical model is proposed to answer Fermi's question. Gamma-ray bursts have the correct rates of occurrence and plausibly the
We performed extensive, multi-wavelength observations of the prototypical symbiotic star Z Andromedae between 2000 and 2003, during a large eruption.
We consider a situation in which two metrics are joined at a null hypersurface. It often occurs that the union
Recently several authors have proposed stochastic evolutionary models for the growth of the web graph and other networks that give
ROSAT HRI observations show complicated substructure in the X-ray surface brightness within $\sim$5 arcminutes around NGC 1275 -- the dominant
The purpose of this paper is to develop a "calculus" on graphs that allows graph theory to have new connections
Charm fragmentation and dijet angular distributions have been measured in $D^*$ photoproduction at HERA. Charm fragmentation and its property of
The results of a recent experiment with $^{85}$Rb Bose-Einstein condensates are analyzed within the mean-field approximation including dissipation due to
The maximum value of the superconducting transition temperature Tc due to a phonon-mediated interaction was estimated by Cohen and Anderson
