Advanced Science, EarlyView.Clinical intramuscular thymus transplantation yields only short‐lived efficacy and marginal therapeutic benefits. Benefiting from the spleen's intrinsic strengths—rapid vascular perfusion, abundant developmental factors, and resident progenitors—the intrasplenic thymic grafts achieve robust thymic regeneration and substantial T‐cell reconstitution ...

Chaotic Attributes and Permutative Optimization
, 2016 Population dynamics and its relation to chaotic systems is analyzed in this Chapter. Using basic chaotic principles of attractors and edges, a dynamic population is developed, which is used to induce and retain diversity in a metaheuristic population ...

Advanced Science, EarlyView.Heteroatom precursor engineering serves as a molecular‐level strategy to tailor hydrazide monomer reactivity and diffusion kinetics, enabling controlled assembly of highly crystalline COF membranes with ultramicroporous channels. The nitrogen‐enriched nanochannels deliver high water/ion selectivity via simultaneous water transport acceleration and ion ...

Spontaneous Cyclic Levitation of Glycerol‐Water Droplets at Low Pressures
Advanced Science, EarlyView.Under low pressure, a minute glycerol addition transforms the chaotic dynamics of freezing water droplets into cyclic levitation. Freeze‐concentration preserves liquid pathways that relax expansion‐induced stress, while freezing point depression weakens asymmetric vaporization recoil.

A NOVEL CHAOTIC DYNAMICAL SYSTEM
Far East Journal of Dynamical Systems, 2006 In this paper we introduce a novel chaotic dynamical system. Some basic dynamical properties, such as strange attractor, continuous spectrum, Lyapunov exponents, fractal dimension and Poincaré mapping of the new chaotic system are studied. Its chaotic dynamical behaviors are established by numerical simulation and theoretical analysis.

Controlling chaos in a chaotic neural network [PDF]
, 2003 The chaotic neural network constructed with chaotic neuron shows the associative memory function, but its memory searching process cannot be stabilized in a stored state because of the chaotic motion of the network.

Advanced Electronic Materials, EarlyView.Physical reservoir computing (PRC) based on spin wave interference has demonstrated high computational performance, yet room for improvement remains. In this study, we fabricated this concept PRC with eight detectors and evaluated the impact of the number of detectors using a chaotic time series prediction task.

Effect of noise filtering on predictions : on the routes of chaos [PDF]
The detection of chaotic behaviors in commodities, stock markets and weather data is usually complicated by large noise perturbation inherent to the underlying system.
