Long-range correlations and nonstationarity in the Brazilian stock market
, 2003 We report an empirical study of the Ibovespa index of the Sao Paulo Stock Exchange in which we detect the existence of long-range correlations. To analyze our data we introduce a rescaled variant of the usual Detrended Fluctuation Analysis that allows us

Analysis of Solar Neutrino Data from Super-Kamiokande I and II
Entropy, 2014 We are going back to the roots of the original solar neutrino problem: the analysis of data from solar neutrino experiments. The application of standard deviation analysis (SDA) and diffusion entropy analysis (DEA) to the Super-Kamiokande I and II data ...

Multi-scale entropy analysis and Hurst exponent [PDF]
Physica A: Statistical Mechanics and its Applications, 2019 Abstract Several methods exist for measuring the complexity in a system through analysis of its associated time series. Multi-scale entropy appears as a successful method on this matter. It has been applied in many disciplines with great achievements. For example by analysis of the bio-signals, we are able to diagnose various diseases.

Australia and the Path Not Taken: The Declining Independence and Influence of Middle Powers
Global Policy, EarlyView.ABSTRACT Australian foreign policy has famously been distinguished by the search for ‘great and powerful friends’. However, Australia's relationship with its current notional protector and key ally—the United States—has generally had more costs than benefits and, I argue, has consequently not been in Australia's much‐invoked ‘national interest ...

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 ...
