This paper introduces fractal probability theory, a novel extension to standard probability theory that incorporates a fundamental balance between probability and its complement. For any event A with standard probability µ(A), we define a fractal probability measure µr(A) = (1 − r)µ(A) + rµ(Ac), where r ∈ [0, 1/2] is the fractal ratio parameter ...

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT The rotor system of an electrically assisted turbocharger (EAT) is composed of multiple shaft components; The nonlinear connection and contact effects make it difficult to determine the system dynamic characteristics. To improve the modeling accuracy of EAT rotor system and evaluate the influence of contact between multi‐axis components and ...

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT Fractional calculus, with its unique advantage in describing memory and nonlocal effects, has become a key tool for modeling nonlinear dynamic systems. Its integration with circuit systems has opened up a new paradigm for modern circuit design.

Mobilizing Presence across Borders: Devotion to Papua New Guinea's Blessed Peter To Rot in Australia
Oceania, EarlyView.ABSTRACT This article engages with the conjunctures between migration and religion by focusing on the celebration of Papua New Guinea's ‘National Patron Saint’, the Blessed Peter To Rot, in the Australian diaspora. Both in Sydney and Brisbane, Catholic Papua New Guinea (PNG) migrants have been ‘relocating’ PNG shrines, regalia, relics and ritual ...

Fractalism Theory: The General Theory of Fractalism
This record presents the canonical first edition of Fractalism Theory: The General Theory of Fractalism, a comprehensive theoretical framework developed by Siamak Sepehrian. The theory investigates fractals not merely as geometric forms, but as relational entities whose identity, meaning, adaptation, emergence, organization, and development ...

Population recovery of an endangered macaw enhances long‐distance seed dispersal via stomatochory
Oikos, EarlyView.Seed dispersal by large, mobile vertebrates plays a key role in shaping plant spatial dynamics and community structure. However, how variation in animal population size influences the magnitude and spatial scale of seed dispersal remains poorly understood.

Scaling turbulence drives the general circulation
Quarterly Journal of the Royal Meteorological Society, EarlyView.The NOAA Gulfstream SP4, which deployed the GPS dropsondes over the NE Pacific Ocean as part of the Winter Storms Project during the January–March periods of 2004, 2005 and 2006. Abstract Statistical multifractal analysis of airborne and dropsonde observations is used to show that persistence of velocity after molecular collisions breaks the continuous
