Spatiotemporal chaotic one-way Hash function construction based on coupled tent maps

Tongxin xuebao, 2007
A novel coupled tent maps-based spatiotemporal chaotic cryptographic Hash function was proposed.Compared with the discrete tent map,the coupled discrete tent spatiotemporal chaotic maps have longer computer-realization-period,nearly uniform distribution ...

Construction of a New Discrete Chaotic Mapping Based on the Robust Chaos Theorem

Mathematics
Chaotic systems serve as fundamental pseudo-random sequence generators in encryption algorithms and play a vital role in communication security. However, most current research still focus on the classical Logistic chaotic map, making it vulnerable to ...

Sound‐Based Assembly of Magnetically Actuated Soft Robots Toward Enhanced Release of Extracellular Vesicles

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Magnetic soft robots offer promise in biomedicine due to their wireless actuation and rapid response, but current fabrication methods are complex and have limited cellular compatibility. A new, contactless bioassembly strategy using hydrodynamic instabilities is introduced, enabling customizable, centimeter‐scale robots.

Field‐Programable Dynamics in a Soft Magnetic Actuator Enabling True Random Number Generation and Reservoir Computing

Advanced Intelligent Systems, EarlyView.
Complex dynamics, often avoided in electromechanical design, can enhance soft robotics. We develop durable magnetic soft actuators operating in tunable dynamic regimes, enabling random number generation, stochastic computing, and time‐series prediction.

General Construction Method and Proof for a Class of Quadratic Chaotic Mappings

Mathematics
The importance of chaotic systems as the main pseudo-random cryptographic generator of encryption algorithms in the field of communication secrecy cannot be overstated, but in practical applications, researchers often choose to build upon traditional ...

Negotiating contested spaces and places: Narratives of social suffering and resistance in racialized Cape Town communities

American Journal of Community Psychology, EarlyView.
Abstract This study employs a schizocartographic approach to explore community narratives of space, memory, and violence in Kraaifontein, Cape Town. Through participants' accounts, ordinary places—gardens, shops, blocks, sports grounds, and streets—emerge as ambivalent geographies where trauma, resilience, and belonging intersect.
