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

Alignment, Rising, Sticking, and Phototaxis: Modulating the Behavior of Hematite Micropeanuts
Advanced Materials Interfaces, EarlyView.Although a rich variety of behaviors, such as rising and phototaxis, are observed with light‐activated semiconductor microparticles, the experimental conditions under which such behaviors occur have not been elucidated. In this study, pH, fuel concentration, and light intensity are varied, revealing diverse behaviors of hematite microparticles.

Critical Neumann problem for nonlinear elliptic systems in exterior domains
Electronic Journal of Differential Equations, 2008 In this paper, we investigate the Neumann problem for a critical elliptic system in exterior domains. Assuming that the coefficient $Q(x)$ is a positive smooth function and $lambda$, $mugeq0$ are parameters, we examine the common effect of the mean ...

Advanced Materials Interfaces, EarlyView.This work presents a novel strategy for nanocomposite fabrication that imparts high shear and elongational forces, overcoming the interlayer van der Waals forces within bulk 2D materials and facilitating their exfoliation in elastomers. Additionally, the high shear forces promote effective nanoparticle dispersion and in situ bond formation, leading to ...

In Situ Manipulation of Growth Mechanisms in the Vapor–Solid–Solid Growth of GaP Nanowires
Advanced Materials Interfaces, EarlyView.The direct observation of the Ni‐assisted GaP nanowire growth process via transmission electron microscopy reveals two different growth mechanisms by Trimethylgallium (TMGa) precursor supply variations. The decrease of TMGa flow results in the formation of Ni2P phase as growth promoters with cation exchange reaction in addition to interface diffusion ...

Existence results for Hamiltonian elliptic systems with nonlinear boundary conditions
Electronic Journal of Differential Equations, 1999 We prove the existence of nontrivial solutions to the system $$ Delta u = u, quad Delta v = v, $$ on a bounded set of $R^N$, with nonlinear coupling at the boundary given by $$partial u/partialeta = H_v,quad partial v/partialeta = H_u,.$$ The proof is ...

Advanced Materials Interfaces, EarlyView.A novel and efficient method is explored to synthesize 1D single‐crystal sub‐stoichiometric WnO3n‐2 (n = 25) nanowire bundles. The approach utilizes selective low‐energy He+ ion irradiation (27 eV) on Mo‐Ni doped WOx surface, achieving efficient catalyst‐free self‐organized growth of high aspect ratio nanowires at the temperature of 700 °C.

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.
