Group homomorphisms as error correcting codes [PDF]
, 2014 We investigate the minimum distance of the error correcting code formed by the homomorphisms between two finite groups $G$ and $H$. We prove some general structural results on how the distance behaves with respect to natural group operations, such as ...

Energy Extraction From Gravitational Collapse to Static Black Holes
, 2002 The mass--energy formula of black holes implies that up to 50% of the energy can be extracted from a static black hole. Such a result is reexamined using the recently established analytic formulas for the collapse of a shell and expression for the ...

Viscosity of Colloidal Suspensions
, 1996 Simple expressions are given for the Newtonian viscosity $\eta_N(\phi)$ as well as the viscoelastic behavior of the viscosity $\eta(\phi,\omega)$ of neutral monodisperse hard sphere colloidal suspensions as a function of volume fraction $\phi$ and ...

Understanding the recovery of rare-earth elements by ammonium salts [PDF]
, 2018 While the recovery of rare earth elements (REEs) from aqueous solution by ionic liquids (ILs) has been well documented, the metal compounds that are formed in the organic phase remain poorly characterized.

Reaction-Diffusion in Nonsmooth and Closed Domains
Boundary Value Problems, 2007 We investigate the Dirichlet problem for the parabolic equation in a nonsmooth and closed domain possibly formed with irregular surfaces and having a characteristic vertex point.

Star Formation Efficiency in the Central 1 kpc Region of Early-Type Spiral Galaxies [PDF]
, 2000 It has been reported recently that there are some early-type spiral (Sa--Sab) galaxies having evident star-forming regions which concentrate in their own central 1-kpc.

Star Formation Rate from Dust Infrared Emission [PDF]
, 2002 We examine what types of galaxies the conversion formula from dust infrared (IR) luminosity into the star formation rate (SFR) derived by Kennicutt (1998) is applicable to.

Weak consistency and strong paraconsistency
tripleC: Communication, Capitalism & Critique, 2009 In a standard sense, consistency and paraconsistency are understood as, respectively, the absence of any contradiction and as the absence of the ECQ (“E contradictione quodlibet”) rule that allows us to conclude any well formed formula from any ...

On the V-Line Radon Transform and Its Imaging Applications
International Journal of Biomedical Imaging, 2010 Radon transforms defined on smooth curves are well known and extensively studied in the literature. In this paper, we consider a Radon transform defined on a discontinuous curve formed by a pair of half-lines forming the vertical letter V.
