We point out that $Λ$CDM cosmology has an ignored assumption. That is, the $Λ$ component of the universe moves synchronously
The latest finding by Hester et al. supports the view of ". . . iron cores of the inner planets,
Researchers have long proposed using economic approaches to resource allocation in computer systems. However, few of these proposals became operational,
The initial surface reactions of the extrinsic coagulation pathway on live cell membranes were examined under flow conditions. Generation of
We discuss why the N_6=1 heterotic string has to be viewed as something similar to a ``non-compact orbifold''. Only the
In the context of string theory we argue that higher dimensional Dp-branes unwind and evaporate so that we are left
We start from the pure Einstein-Hilbert action in Metric Affine Gravity, with the orthonormal metric. We get an effective Levi-Civita
Several studies have indicated that the local cosmic velocity field is rather cold, in particular in the regions outside the
In this paper I argue that, far from necessarily hindering bar formation in disc galaxies, inner haloes may stimulate it.
Radionuclides with half-lives ranging from some years to billions of years presumably synthesized outside of the solar system are now
I discuss the dynamical interaction of galactic disks with the surrounding dark matter halos. In particular it is demonstrated that
I present a fast algorithm to find apparent horizons. This algorithm uses an explicit representation of the horizon surface, allowing
Robert French has argued that a disembodied computer is incapable of passing a Turing Test that includes subcognitive questions. Subcognitive
The anthropic principle has been proposed as an explanation for the observed value of the cosmological constant. Here we revisit
Some general aspects of the AdS_2/CFT_1 correspondence, previously discussed in hep-th/9812073, are summarized. The majority of this summary is devoted
We argue that in classical and quantum theories of gravity the configuration space and Hilbert space may not be constructible
We examine the axion model in the large extra dimensions scenario with TeV scale gravity. To obtain an intermediate-scale decay
Biological approximations, which are universal for diverse species, are well known. With no other experimental data, their invariance to transformations
For the bosonic string on the torus we compute boundary states describing branes with not trivial homology class in presence
We point out that models where gauge and charged matter fields live on the world volume of D3 branes can
In Hamiltonian time-dependent mechanics, the Poisson bracket does not define dynamic equations, that implies the corresponding peculiarities of describing time-dependent
We trace the origin of the cosmological constant problem to the assumption that Newton's constant $G$ sets the scale for
Questions such as whether we live in a spatially finite universe, and what its shape and size may be, are
The flat matter dominated Universe that dominated cosmological model building for much of the past 20 years does not correspond
