Programmable Information Processing With Reconfigurable Self‐Contact Variable Stiffness Mechanical Metamaterial

Advanced Science, EarlyView.
Reconfigurable self‐contact variable stiffness metamaterials based on shape memory polymers enable programmable stiffness switching. Static arrays store and encrypt information with immunity to electromagnetic interference, while asymmetric stiffness converts symmetric vibration into directional matter transport.

Collagen‐Binding IL‐15 Immunocytokine Armed Oncolytic Adenovirus Establishes a Self‐Reinforcing Immunostimulatory Milieu to Potentiate Antitumor Immunity

Advanced Science, EarlyView.
Repurposing the dense tumor stroma from a physical barrier into an anchoring scaffold, an engineered oncolytic adenovirus encoding IL15C‐CBD overcomes the immunosuppressive microenvironment in triple‐negative breast cancer. Intratumoral viral replication secretes this collagen‐anchored immunocytokine, forming a localized cytokine depot.

Approximately-Finite Memory and Discrete-Time Input–Output Maps

International Journal of Circuit Theory and Applications, 2000
A body of results is given concerning the character of the response of systems represented by discrete-time approximately-finite-memory input-output maps \(G\) with input and output defined on \(\{0,1,\dots\}\). Conditions are given under which, for example, the system's output approaches a limit as \(k\to\infty\) whenever the input does. Of particular

Complete Memory Structures for Approximating Nonlinear Discrete-Time Mappings

IEEE Transactions on Neural Networks, 1997
This paper introduces a general structure that is capable of approximating input-output maps of nonlinear discrete-time systems. The structure is comprised of two stages, a dynamical stage followed by a memoryless nonlinear stage. A theorem is presented which gives a simple necessary and sufficient condition for a large set of structures of this form ...

Design of a discrete memristive chaotic map: fractional-order memory, dynamics and application

Physica Scripta
Abstract In this paper, a discrete fracmemristor (DFM) model is derived based on the Caputo difference, and a new fractional-order chaotic map is designed. Dynamics of the proposed map is investigated in detail by means of Lyapunov exponent spectra, bifurcation diagrams, PE complexity and multistability analyses.

Fractional Dynamics and Discrete Maps with Memory

2010
The study of nonlinear dynamics in terms of discrete maps is a very important step m understanding the qualitative behavior of physical systems described by differential equations (Sagdeev et al., 1988; Zaslavsky, 2005; Chirikov, 1979; Schuster and Just, 2005; Collet and Eckman, 1980).
