Advanced Healthcare Materials, EarlyView.What if human skin could remain fully alive and functional outside the body for weeks? A New Alternative Method (NAM) based on a vascularized full‐thickness skin microphysiological system achieves precisely this, preserving native vasculature, resident immunity, and metabolic activity for up to three weeks, while faithfully recapitulating radiation ...

Ferroelectric Quantum Dots for Retinomorphic In‐Sensor Computing
Advanced Materials, EarlyView.This work has provided a protocol for fabricating retinomorphic phototransistors by integrating ferroelectric ligands with quantum dots. The resulting device combines ferroelectricity, optical responsiveness, and low‐power operation to enable adaptive signal amplification and high recognition accuracy under low‐light conditions, while supporting ...

Multifractal analysis of the convergence exponent in continued fractions
, 2019 Let $x \in [0,1)$ be a real number and denote its continued fraction expansion by $[a_1(x),a_2(x), a_3(x),\cdots]$. The convergence exponent of these partial quotients is defined as \[ τ(x):= \inf\left\{s \geq 0: \sum_{n \geq 1} a^{-s}_n(x)

Exponent of convergence of solutions of LDE in the unit disc
Novi Sad Journal of Mathematics, 2016 Summary: In this paper, we investigate the exponent of convergence of \(f^{(i)}-\varphi\) where \(f^{(0)}=f\not\equiv 0\) is a solution of linear differential equations with meromorphic coefficients in the unit disc and \(\varphi\) is a small function of \(f\). Our investigation is based on the behavior of the coefficients in a subset \(\Gamma\) of the

Lyapunov exponents of renewal equations: Numerical approximation and convergence analysis
Discrete and Continuous Dynamical Systems - BWe propose a numerical method for computing the Lyapunov exponents of renewal equations (delay equations of Volterra type), consisting first in applying a discrete QR technique to the associated evolution family suitably posed on a Hilbert state space and second in reducing to finite dimension each evolution operator in the obtained time sequence.
