Compound synchronization for four chaotic systems of integer order and fractional order
, 2014 By combining the tracking control and the stability theory of nonlinear fractional-order systems, a novel kind of compound synchronization among four chaotic systems of integer order and fractional order has been investigated, where the drive systems ...

A Polar Topology Network Induces Elastic Stiffening in Ferroelectric Oxide Superlattices
Small, EarlyView.The periodicity in BiFeO3/SrTiO3 superlattices tunes the system into a dense, elastically constrained polar texture state. This topology‐rich regime reveals a collective mechanical response in which interactions among polar topological defects restrict local deformations, producing a pronounced elastic stiffening.

Infinitely many hidden attractors in a new fractional-order chaotic system based on a fracmemristor
, 2019 Memristor and fractional-order derivatives are feasible options for constructing new systems with complex dynamics. This paper presents a new fractional-order chaotic system based on a fractional-order memristor (fracmemristor).

Programmable Porosity in Polymers via Microfluidic Templating and 3D Printing
Small Methods, EarlyView.Fluid templating is a powerful way to produce porous polymers. Microfluidic technologies enable fine control over the dimension and packing of bubbles and droplets. Combined with additive manufacturing, microfluidic templating enables the creation of polymeric functionally graded porous materials in which both porosity and three‐dimensional geometry ...

Influence of natural fibers on physical, mechanical, and fire‐resistant properties of microconcrete
Structural Concrete, EarlyView.Abstract This study examined the influence of natural fibers on the physical, mechanical, and fire‐resistant properties of microconcrete, in comparison with conventional polypropylene fibers used in cement composites. The fibers were characterized by FTIR and TGA/DSC to assess their composition and thermal stability, and FTIR was also performed after ...

Working‐Class Muscles? Co‐Operative Gyms in Interwar Britain
History, EarlyView.Abstract The Health & Strength League's network of co‐operative gymnasiums constituted one of interwar Britain's most significant yet overlooked physical culture institutions, affiliating over 800 gyms across Britain and Ireland by 1939. Drawing on Health & Strength magazine's editorial content and reader contributions, this article argues that these ...

The British Journal of Sociology, EarlyView.ABSTRACT How are capital and the family interconnected in contemporary capitalism? In this article, we argue that they come together in owning relations. By owning capital across generations, families bridge the temporal gap between the durability of capital and the finite lifespan of private property holders and thus resolve the problem of bona ...

The British Journal of Sociology, EarlyView.ABSTRACT Tracing the early adoption of computer gang databases by the Los Angeles County Sheriff's Department and the Los Angeles Police Department in the 1980s to the deployment of computationally‐assisted surveillance during the Vietnam War, this paper uses a genealogical approach to compare surveillance technologies developed across the arc of ...
