Advanced Functional Materials, EarlyView.A tubular electrowetting pump moves alternating droplets through a millimeter‐wide channel in discrete, reversible steps, functioning as a fluidic stepper motor. With no moving parts and electrodes insulated from the liquid, it delivers silent, accurate flow. Flexibility allows the pump to be woven directly into textiles for wearable, medical, and soft‐

Forced oscillations for delay motion equations on manifolds
Electronic Journal of Differential Equations, 2007 We prove an existence result for $T$-periodic solutions of a $T$-periodic second order delay differential equation on a boundaryless compact manifold with nonzero Euler-Poincare characteristic.

Make‐Use‐Remake: Toward Indefinite Low‐Temperature Material Loops
Advanced Functional Materials, EarlyView.We introduce a regenerable materials platform built from microparticles bound by a temperature‐responsive polymer shell, enabling strong, processable structures from diverse feedstocks. The material is shaped at low temperatures (80°C) using common manufacturing methods and reprocessed repeatedly in the presence of water, demonstrating stable ...

Memristive‐Gated RC‐Delay Synaptic Transistors for Time‐Encoded Analog in‐Memory Computing
Advanced Functional Materials, EarlyView.A Memristive‐Gated Transistor for Time‐Encoded Analog In‐Memory Computing — By exploiting the RC delay of a self‐rectifying interface‐type memristor, nonlinear I–V distortion is structurally bypassed, enabling 3‐bit nonvolatile memory, spike‐timing‐based analog encoding, and hardware‐calibrated reservoir‐computing validation within a unified device ...

Multiplicity of forced oscillations for scalar differential equations
Electronic Journal of Differential Equations, 2001 We give, via topological methods, multiplicity results for small periodic perturbations of scalar second order differential equations. In particular, we show that the equation $$ ddot{x} = g(x)+varepsilon f(t,x,dot x), $$ where $g$ is $C^1$ and $f$ is ...

Advanced Functional Materials, EarlyView.We present a scalable EC/TC hybrid smart window using a DCPE that enables tunable solar modulation (ΔTsol:15–43%), fast electrochromic switching (<90 s), and strong thermal blocking (10–14°C reduction). HPMC improves thermal stability, while an optimized ISL enhances EC performance.

Sensitivity analysis of stochastically forced quasiperiodic self-oscillations
Electronic Journal of Differential Equations, 2016 We study a problem of stochastically forced quasi-periodic self-oscillations of nonlinear dynamic systems, which are modelled by an invariant torus in the phase space.

A 3D Human Neuron‐on‐Chip Platform to Monitor Neuronal Injury Responses
Advanced Healthcare Materials, EarlyView.This study presents a novel 3D Neuron‐on‐Chip model that can maintain human PSC‐derived excitatory prefrontal cortex neurons in 3D hydrogels and can be used to monitor neuronal injury responses over time. Results show injury‐induced acute neuronal excitotoxicity, declining neuronal connectivity, and the activation of a neurodegenerative, SASP‐like ...

Oscillators: Phenomenological mappings and analogies: Second part: Structural analogy and chains [PDF]
Scientific Technical Review, 2015 New analytical and numerical results of dynamics for both linear and nonlinear system with two degrees of freedom are presented. For the mechanical chain system with two degrees of freedom, oscillations are investigated analytically and numerically with ...

Advanced Healthcare Materials, EarlyView.This review examines how cellular behavior is regulated by mechanical cues transmitted through soft biomaterials, from single‐cell mechanosensing to tissue‐level adaptation. It highlights why physiological relevance, rather than model complexity alone, is critical for translational mechanobiology and introduces a scoring framework linking material ...
