Primary Sequences of Protein-Like Copolymers: Levy Flight Type Long Range Correlations

, 2001
We consider the statistical properties of primary sequences of two-letter HP copolymers (H for hydrophobic and P for polar) designed to have water soluble globular conformations with H monomers shielded from water inside the shell of P monomers. We show,

Fractal and nonfractal behavior in Levy flights [PDF]

Journal of Mathematical Physics, 1987
The d-dimentional space-continuous time-discrete Markovian random walk with a distribution of step lengths, which behaves like x−(α+d) with α>0 for large x, is studied. By studying the density–density correlation function of these walks, it is determined under what conditions the walks are fractal and when they are nonfractal.

Direct observation of Levy flight of holes in bulk n-InP

, 2012
We study the photoluminescence spectra excited at an edge side of n-InP slabs and observed from the broadside. In a moderately doped sample the intensity drops off as a power-law function of the distance from the excitation - up to several millimeters ...

Super-diffusion around the rigidity transition: Levy and the Lilliputians

, 2010
By analyzing the displacement statistics of an assembly of horizontally vibrated bidisperse frictional grains in the vicinity of the jamming transition experimentally studied before, we establish that their superdiffusive motion is a genuine Levy flight,

Why Should we Worry about Nigeria's Fragile Security?

The Political Quarterly, EarlyView.
Abstract This paper explores the multifaceted implications of Nigeria's persistent security crisis, highlighting its domestic, regional and global consequences. It examines the humanitarian toll, economic disruption, poverty, food insecurity and the erosion of social cohesion within Nigeria. Regionally, it analyses how Nigeria's instability exacerbates

Radio-wave propagation in the non-Gaussian interstellar medium

, 2005
Radio waves propagating from distant pulsars in the interstellar medium (ISM), are refracted by electron density inhomogeneities, so that the intensity of observed pulses fluctuates with time.

Photonic superdiffusive motion in resonance line radiation trapping - partial frequency redistribution effects [PDF]

, 2007
The relation between the jump length probability distribution function and the spectral line profile in resonance atomic radiation trapping is considered for Partial Frequency Redistribution (PFR) between absorbed and reemitted radiation. The single line

Interactive Levy Flight in Interest Space

, 2017
Compared to the well-studied topic of human mobility in real geographic space, very few studies focus on human mobility in virtual space, such as interests, knowledge, ideas, and so forth. However, it relates to the issues of management of public opinions, knowledge diffusion, and innovation.

BaYaka forager and Bantu fisher‐farmer adolescent engagement with intensifying market integration in the Republic of the Congo Participation des adolescents BaYaka chasseurs‐cueilleurs et Bantous pêcheurs‐agriculteurs à l'intégration croissante au marché en République du Congo

Journal of the Royal Anthropological Institute, EarlyView.
A substantial body of anthropological research has investigated how subsistence communities engage with market‐based economies. In this study, we contribute to this body of work by examining adolescent orientations towards intensifying market integration in the Congo Basin.
