A Practical Noise2Noise Denoising Pipeline for High‐Throughput Raman Spectroscopy
Advanced Engineering Materials, EarlyView.A lightweight and reproducible denoising pipeline for high‐throughput Raman spectroscopy is introduced, based on a 1D convolutional autoencoder trained with a Noise2Noise strategy. Using only repeated short‐exposure acquisitions, the method suppresses stochastic noise without reference spectra, enabling reliable spectral reconstruction while preserving

Hybrid Metal–Carbon Ink for Printed Stretchable Temperature Sensors
Advanced Engineering Materials, EarlyView.We prepare conductive inks for temperature sensing with silver flakes and carbon or graphite flakes in a silicone elastomer matrix. Silver dominates the temperature‐dependent conductivity, while the carbon filler network ensures the stability of the conductive pathways and retains function under strain.

ALGEBRAIC NONLINEARITY IN VOLTERRA-HAMMERSTEIN EQUATIONS [PDF]
Journal of Sciences, Islamic Republic of Iran, 1999 Here a posteriori error estimate for the numerical solution of nonlinear Voltena- Hammerstein equations is given. We present an error upper bound for nonlinear Voltena-Hammastein integral equations, in which the form of nonlinearity is algebraic and ...

A Singular Nonlinear Volterra Integral Equation
Journal of Integral Equations and Applications, 1993 Many problems in Applied Mathematics lead to the study of the nonlinear partial differential equation \(u_ t = (a(u))_{xx} + (b(u))_ x + c(u)\). The interest in the existence of travelling-wave solutions of the form \(U(x,t) = U(\psi)\), \(\psi = x - \lambda t\), originates an ordinary differential equation from which arise integral equations of the ...

Nonlinear Operations and the Solution of Integral Equations [PDF]
Transactions of the American Mathematical Society, 1978 The letters 5, G and H denote a linearly ordered set, a normed complete Abelian group with zero element 0, and the set of functions from G to G that map O into 0, respectively. In addition, if Z E H and there exists an additive function a from S x S to the nonnegative numbers such that 11 Y(x, y)P-V(x, y)Q 11 < a(x, Y)llP-Q 12 for each {x, y, P, Q } in

Spin Injection Of Exciton–Polaritons With Halide Perovskites At Room Temperature
Advanced Functional Materials, EarlyView.A monolithic Tamm‐plasmon microcavity embedding a two‐dimensional halide perovskite enables room‐temperature spin injection of exciton‐polaritons under quasi‐resonant optical excitation. Polarization‐resolved spectroscopy reveals partial preservation of the injected spin in the lower polariton branch, while bare excitons remain fully depolarized.

Existence Theorem for Integral and Functional Integral Equations with Discontinuous Kernels
Abstract and Applied Analysis, 2012 Existence of extremal solutions of nonlinear discontinuous integral equations of Volterra type is proved. This result is extended herein to functional Volterra integral equations (FVIEs) and to a system of discontinuous VIEs as well.
