Generalized Synchronization of Stochastic Discrete Chaotic System with Poisson Distribution Coefficient

Discrete Dynamics in Nature and Society, 2013
This paper addresses the generalized synchronization of stochastic discrete chaotic systems with Poisson distribution coefficient. Firstly, based on the orthogonal polynomial approximation theory of discrete random function in Hilbert spaces, the ...

In Situ Construction of Phosphorus‐Containing Crosslinked Urethane Network Combined With Ammonium Polyphosphate via Reactive Blending for Enhancing Flame Retardancy and Anti‐Dripping Performance of Polylactic Acid Composites

Safety Science and Technology, EarlyView.
By in situ reaction blending, DOPO‐HQ and THEIC were added to PLA with MDI to construct a phosphorus containing polyurethane network, which significantly improved the flame retardant and anti‐dripping properties of polylactic acid composites. ABSTRACT Polylactic acid (PLA) is highly flammable and prone to severe melt dripping during combustion, which ...

Experimental synchronization of multiscroll chaotic attractors using current-feedback operational amplifiers

, 2011
We present the experimental synchronization of two multiscroll chaotic attractors realized with current-feedback operational amplifiers. The synchronization is performed by applying Hamiltonian forms and observer approach.

Bursting Oscillation Characteristics and Improved AHODFC for DFIG and PMSG Combined Wind Farm

Energy Internet, EarlyView.
ABSTRACT Bursting oscillations occur in DFIG and PMSG combined wind farm under external disturbances and lead to the instability problems. To reveal the bursting oscillation characteristics and develop a suppression method, a fast‐slow dynamics analysis method and an improved adaptive high‐order differential feedback controller (AHODFC) based on ...

NOCTURNAL INFORMALITY: Rethinking the Temporal Politics of Urban Informality

International Journal of Urban and Regional Research, EarlyView.
Abstract Urban informality has long been theorized as a spatial condition of urban life—an expression of negotiation, improvisation, and survival within the uneven terrains of legality and governance. Yet this emphasis on space has obscured the temporalities through which informality is lived, governed, and contested. This essay develops the concept of

Rebuilding the Ladder? Contemporary Contests Over Industrial Policy

Global Policy, EarlyView.
ABSTRACT Does the greater embrace of industrial policy globally signal the emergence of a New Washington Consensus? We show that the multiplication of industrial policies, while consequential, signals neither normalisation nor consensus. Rather, industrial policy is increasingly the object of contestation over norms and practices of state ...

Dynamics Analysis and Adaptive Synchronization of a Class of Fractional-Order Chaotic Financial Systems

Fractal and Fractional
It is of practical significance to realize a stable and controllable financial system by using chaotic synchronization theory. In this paper, the dynamics and synchronization are studied for a class of fractional-order chaotic financial systems.

SAGE: Structure‐Aware Generative Video Transitions between Diverse Clips

Computer Graphics Forum, EarlyView.
Abstract Video transitions aim to synthesize intermediate frames between two clips, but naïve approaches such as linear blending introduce artifacts that limit professional use or break temporal coherence. Traditional techniques (cross‐fades, morphing, frame interpolation) and recent generative inbetweening methods can produce high‐quality plausible ...

General Movement Assessment in infancy and later cognitive outcomes: A systematic review and meta‐analysis

Developmental Medicine &Child Neurology, EarlyView.
Aim To evaluate whether the General Movement Assessment (GMA) in infancy is associated with later cognitive outcomes from early childhood through adulthood. Method Cohort and case–control studies examining associations between Prechtl's GMA and cognitive outcomes from 6 months of age were eligible.

Volatility ≠ Risk: When Timing Alpha in Crypto Markets Reflects Mispricing

Financial Review, EarlyView.
ABSTRACT Volatility timing in cryptocurrency markets generates significant alpha, but only during periods of loose monetary policy and high uncertainty. Analyzing S&P crypto indices (2017–2023) dominated by large‐cap assets, we show realized volatility can reflect noise‐driven speculative flows, not risk compensation. This effect is strongest for small‐
