A powerlaw break in the nearinfrared power spectrum of the Galactic center black hole
, 902
"... Proposed scaling relations of a characteristic timescale in the Xray power spectral density of galactic and supermassive black holes have been used to argue that the accretion process is the same for small and large black holes. Here, we report on the discovery of this timescale in the nearinfrare ..."

MPI–PhT/200031 Lepton asymmetry creation in the Early Universe.
, 2000
"... Oscillations of active to sterile neutrinos with a small mixing angle sin 2θ < 10 −2 could generate a large lepton asymmetry in the Early Universe. The final order of magnitude of the lepton asymmetry η is mainly determined by its growth in the last stage of evolution, the so called powerlaw reg ..."

1 Large Amplitude Oscillatory Shear Flow of Gluten Dough; A Model Powerlaw Gel
, 2011
"... In a previous paper [Ng and McKinley (2008)], we demonstrated that gluten gels can best be understood as a polymeric network with a powerlaw frequency response that reflects the fractal structure of the gluten network. Large deformation tests in both transient shear and extension show that in the a ..."

www.elsevier.com/locate/ces Steady flow of powerlaw fluids across an unconfined elliptical cylinder
, 2006
"... The momentum transfer characteristics of the powerlaw fluid flow past an unconfined elliptic cylinder is investigated numerically by solving continuity and momentum equations using FLUENT (version 6.2) in the twodimensional steady crossflow regime. The influence of the powerlaw index (0.2n1.8), ..."

, 1987
"... ASYMPTOTIC singular solutions of the HRR type are presented for antiplane shear cracks in ductile crystals. These are assumed to undergo Taylor hardening with a powerlaw relation between stress and strain at sufficiently large strain. Results are given for several crack orientations in fee and bee ..."

Renormalization of earthquake aftershocks
, 1981
"... Assume that each earthquake can produce a series of aftershock independently of its size according to its “local ” Omori’s law with exponent 1+θ. Each aftershock can itself trigger other aftershocks and so on. The global observable Omori’s law is found to have two distinct power law regimes, the fir ..."

Brazilian elections: voting for a scaling democracy. Physica A: Statistical Mechanics and its Applications,
, 2003
"... Abstract The proportional elections held in Brazil in 1998 and 2002 display identical statistical signatures. In particular, the distribution of votes among candidates includes a powerlaw regime. We suggest that the rationale behind this robust scaling invariance is a multiplicative process in whi ..."

Evidence for superexponentially accelerating atmospheric carbon dioxide growth
"... We analyze the growth rates of atmospheric carbon dioxide and human population, by comparing the relative merits of two benchmark models, the exponential law and the finitetimesingular (FTS) power law. The later results from positive feedbacks, either direct or mediated by other dynamical variabl ..."

Powerlawlike stress relaxation of block copolymers: disentanglement regimes
 Macromolecules
, 1993
"... ABSTRACT: We consider stress relaxation in a strongly segregated lamellar mesophase, where block copolymers are in the “brush ” state with junction points confined to the interface between the adjacent lamellae and blocks stretched out away from it. If the molecular weight of the blocks is large eno ..."

Probes of Diffusive Shock Acceleration using GammaRay Burst Prompt Emission
, 901
"... Abstract. The principal paradigm for gammaray bursts (GRBs) suggests that the prompt transient gammaray signal arises from multiple shocks internal to the relativistic expansion. This paper explores how GRB prompt emission spectra can constrain electron (or ion) acceleration properties at the rela ..."
