Exact Hurst exponent and crossover behavior in a limit order market model

, 2002
An exclusion particle model is considered as a highly simplified model of a limit order market. Its price behavior reproduces the well known crossover from over-diffusion (Hurst exponent H>1/2) to diffusion (H=1/2) when the time horizon is increased ...

Norman and Nietzsche: The Political Project of Lindsay's The Magic Pudding

Australian Journal of Politics &History, EarlyView.
Australian artist and writer Norman Lindsay (1879–1969) wrote 11 novels and two children's books, one of which—The Magic Pudding first published in 1918—remains a national classic. This article argues that readers and critics have long misunderstood Lindsay's intention in writing this lengthy cartoon‐story about the adventures of Bunyip Bluegum in ...

Israel's Post‐War Healthcare Obligations

Bioethics, EarlyView.
ABSTRACT Since the beginning of the Israel–Hamas war in 2023, the healthcare infrastructure within Gaza has been dismantled. While international humanitarian law mandates distinction between lawful targets (combatants and military objectives) and non‐lawful targets (civilians and civilian objects), and acknowledging the inherent complexities of ...

Investigation of non linear dynamics of an excitable magnetron sputtering plasma

Results in Physics, 2019
In this paper nonlinear dynamical behaviour of an excitable DC magnetron sputtering plasma has been investigated. Initially, plasma exhibited fixed point dynamics whereas with the increase in the discharge voltage, spikes were observed in the floating ...

Self-affine subglacial roughness: consequences for radar scattering and basal water discrimination in northern Greenland [PDF]

The Cryosphere, 2017
Subglacial roughness can be determined at a variety of length scales from radio-echo sounding (RES) data either via statistical analysis of topography or inferred from basal radar scattering.

Phase Diagram for Turbulent Transport: Sampling Drift, Eddy Diffusivity and Variational Principles [PDF]

, 1999
We study the long-time, large scale transport in a three-parameter family of isotropic, incompressible velocity fields with power-law spectra. Scaling law for transport is characterized by the scaling exponent $q$ and the Hurst exponent $H$, as functions

Balancing and Exploring the Personal, Professional, and Political: Finding Space and Place in the Academy Through Reflexive and Intersecting Masculinities

Journal of Family Theory &Review, EarlyView.
ABSTRACT Using critical intersectional feminist theorizing, I engage in praxis around reflexive masculinities. I discuss my positionality through my personal lived experiences, professional career in academia, and my political engagement. I start by discussing my positionality related to my race, gender, sexual orientation, and family background, and ...
