Data‐Driven Multi‐Objective Optimization of Large‐Diameter Si Floating‐Zone Crystal Growth
Advanced Theory and Simulations, EarlyView.This study presents a surrogate‐based Multi‐Objective Optimization framework for Floating Zone silicon crystal growth. An ensemble of Neural Networks is trained on simulation data and combined with Genetic Algorithms to explore trade‐offs in process parameters.

Photothermal Transport for Guiding Nanoparticles Through the Vitreous Humor
Advanced Science, EarlyView.Nanosecond laser irradiation of the clinically approved dye indocyanine green (ICG) enables light‐guided nanoparticle transport within the vitreous humor. The combined use of ICG and pulsed laser illumination induces localized convection and thermophoresis, directing particles toward illuminated regions.

Stability of Einstein static universe in gravity theory with a non-minimal derivative coupling
European Physical Journal C: Particles and Fields, 2018 The emergent mechanism provides a possible way to resolve the big-bang singularity problem by assuming that our universe originates from the Einstein static (ES) state.

Remarks on Mӧller mistaken famous paper from 1943 [PDF]
Einstein field equations was originally derived by Einstein in 1915 in respect with canonical formalism of Riemann geometry,i.e. by using the classical sufficiently smooth metric tensor, smooth Riemann curvature tensor, smooth Ricci ...

Gravitation as a Quantum Diffusion
, 2003 Inhomogeneous Nelson's diffusion in flat spacetime with a tensor of diffusion can be described as a homogeneous one in a Riemannian manifold with this tensor of diffusion as a metric tensor. The influence of matter to the energy density of the stochastic

Advanced Science, EarlyView.Nanodiamond additives are dispersed in the aqueous electrolyte to organize water molecules, suppress gas evolution and metal corrosion, and guide zinc to deposit more uniformly. Together with enhanced thermal conductivity for fast heat removal, this strategy reduces temperature rise and degradation, enabling safer, more durable rechargeable zinc metal ...

Evaporation‐Driven Solutal Marangoni Control of Rayleigh–Taylor Instability in Inverted Films
Advanced Science, EarlyView.ABSTRACT Inverted liquid films are inherently unstable: gravity amplifies perturbations through the Rayleigh–Taylor instability (RTI), causing rupture and dripping. We show that selective evaporation in volatile binary mixtures can suppress, delay, or transform this instability by inducing solutal Marangoni stresses.

Einstein-{\ae}ther Scalar-tensor Cosmology
, 2021 We propose an Einstein-{\ae}ther scalar-tensor cosmological model. In particular in the scalar-tensor Action Integral we introduce the {\ae}ther field with {\ae}ther coefficients to be functions of the scalar field. This cosmological model extends previous studies on Lorentz-violating theories.
