Deformability of poly(amidoamine) dendrimers
(Springer-Verlag; EDP Sciences, Società Italiana di Fisica, and Springer-Verlag, 2004-05)
Experimental data indicates that poly(amidoamine) (PAMAM) dendrimers flatten when in contact with a substrate, i.e. they are no longer spherical, but resemble flat disks. In order to better understand the deformation ...
Higher-Degree Analogs of the Determinant Line Bundle
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2002-09)
In the first part of this paper, given a smooth family of Dirac-type operators on an odd-dimensional closed manifold, we construct an abelian gerbe-with-connection whose curvature is the three-form component of the ...
Crank-angle resolved imaging of biacetyl laser-induced fluorescence in an optical internal combustion engine
(Springer-Verlag, 2005-09)
The use of a frequency-tripled, diode-pumped Nd:YAG laser in combination with a CMOS camera lens-coupled to a three-stage image intensifier allowed the visualization of the fuel distribution with crank angle resolution for ...
Book Review: The Philosophy of Physics. By Roberto Torretti. Cambridge University Press, Cambridge, United Kingdom, 1999, xvi + 512 pp., $23.95 (softcover)
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2001-05)
Letter: Schwarzschild Atmospheric Processes: A Classical Path to the Quantum
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2000-04)
We develop some classical descriptions for processes in the Schwarzschild string atmosphere. These processes suggest relationships between macroscopic and microscopic scales. The classical descriptions developed in this ...
Invariant measures of nonholonomic flows with internal degrees of freedom
(IOP Publishing Ltd, 2003-09-01)
In this paper we study measure preserving flows associated with nonholonomic systems with internal degrees of freedom. Our approach reveals geometric reasons for the existence of measures in the form of an integral invariant ...
Metastability of breather modes of time-dependent potentials
(IOP Publishing Ltd, 2000-05-01)
We study the solutions of linear Schrödinger equations in which the potential energy is a periodic function of time and is sufficiently localized in space. We consider the potential to be close to one that is time periodic ...
An Integral Spectral Representation of the Propagator for the Wave Equation in the Kerr Geometry
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2005-12)
We consider the scalar wave equation in the Kerr geometry for Cauchy data which is smooth and compactly supported outside the event horizon. We derive an integral representation which expresses the solution as a superposition ...
Massless D-Branes on Calabi–Yau Threefolds and Monodromy
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2005-10)
We analyze the link between the occurrence of massless B-type D-branes for specific values of moduli and monodromy around such points in the moduli space. This allows us to propose a classification of all massless B-type ...
Detecting community structure in networks
(Springer-Verlag; EDP Sciences, Società Italiana di Fisica, and Springer-Verlag, 2004-03)
There has been considerable recent interest in algorithms for finding communities in networks--groups of vertices within which connections are dense, but between which connections are sparser. Here we review the progress ...
