Finite-size versus Surface effects in nanoparticles
, 1999 We study the finite-size and surface effects on the thermal and spatial behaviors of the magnetisation of a small magnetic particle. We consider two systems: 1) A box-shaped isotropic particle of simple cubic structure with either periodic or free ...

Effects of small surface tension in Hele-Shaw multifinger dynamics: an analytical and numerical study [PDF]
, 2002 We study the singular effects of vanishingly small surface tension on the dynamics of finger competition in the Saffman-Taylor problem, using the asymptotic techniques described in [S. Tanveer, Phil. Trans. R. Soc. Lond. A 343, 155 (1993)]and [M. Siegel,

Surface effects in doping a Mott insulator
, 2011 The physics of doping a Mott insulator is investigated in the presence of a solid-vacuum interface. Using the embedding approach for dynamical mean field theory we show that the change in surface spectral evolution in a doped Mott insulator is driven by ...

The surface effect of dentifrices [PDF]
Australian Dental Journal, 2000 AbstractThe aim of this study was to evaluate clinically three commercially available dentifrices and to determine any surface effects on tooth or gingival surfaces. Sixty‐four participants were included in this study and were allocated randomly to one of four treatment groups by an independent person to ensure the investigators were unaware of the ...

Effects on Buildings of Surface Curvature Caused by Underground Coal Mining [PDF]
, 2016 Ground curvature caused by underground mining is one of the most obvious deformation quantities in buildings. To study the influence of surface curvature on buildings and predict the movement and deformation of buildings caused by ground curvature, a ...

Surface magnetic field effects in local helioseismology
, 2007 Using helioseismic holography strong evidence is presented that the phase (or equivalent travel-time) of helioseismic signatures in Dopplergrams within sunspots depend upon the line-of-sight angle in the plane containing the magnetic field and vertical ...
