Magnetic Unclonable Functions Leveraging Remanence and Anhysteretic States
Advanced Functional Materials, EarlyView.A micrometric array of magnetic pillars provides a stable and unclonable hardware for generating cryptographic keys. From a single device, the ability is demonstrated to produce a 470‐bit key while also offering a reconfigurable mode of operation.

A note on nonlinear elliptic systems involving measures
Electronic Journal of Differential Equations, 2000 We study the existence and regularity of solutions to nonlinear elliptic systems whose right-hand side is a measure-valued function. Using a sign condition instead of structure conditions, we obtain the same as those presented by Dolzmann, Hungerbuhler ...

Elliptic Curve Cryptography with Machine Learning
CryptographyElliptic Curve Cryptography (ECC) is a technology based on the arithmetic of elliptic curves used to build strong and efficient cryptosystems and infrastructures. Several ECC systems, such as the Diffie–Hellman key exchange and the Elliptic Curve Digital

Precursor Mineral Phases of Forming Mollusk Shell Nacre: A Study of Hydrated Samples
Advanced Functional Materials, EarlyView.Mineral, organic phase, and water are the essential components in mollusk shell nacre formation. Their interplay is not well understood, because the hydrated material is difficult to observe at high resolution, under close to native conditions. Forming nacre is studied using environmental and cryo‐electron microscopy and hydrated ACC phases, together ...

Solutions to elliptic systems of Hamiltonian type in R^N
Electronic Journal of Differential Equations, 1999 The paper proves existence of a solution for elliptic systems of Hamiltonian type on ${mathbb R}^N$ by a variational method. We use the Benci-Rabinowitz technique, which cannot be applied here directly for lack of compactness.

Elliptic systems at resonance for jumping non-linearities
Electronic Journal of Differential Equations, 2016 In this article, we study the existence of nontrivial solutions for the problem $$\displaylines{ -\Delta u=\alpha _1u^{+}-\beta _1u^{-}+f(x,u,v)+h_1( x) \quad \text{in }\Omega, \cr -\Delta v=\alpha _2v^{+}-\beta _2v^{-}+g(x,u,v)+h_2( x) \quad \text ...
