Statistical properties of an ensemble of vortices interacting with a turbulent field
, 2005 We develop an analytical formalism to determine the statistical properties of a system consisting of an ensemble of vortices with random position in plane interacting with a turbulent field. We calculate the generating functional by path-integral methods.

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions
Advanced Engineering Materials, EarlyView.This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

Newtonian scattering in Hilbert space
Journal of Mathematical Analysis and Applications, 1990 The theory of scattering for classical Newtonian mechanics has been some what neglected. The authors study in detail the case of a particle in a potential field \(F(x)=-V'(x)\in C^ 1({\mathbb{R}})\), \(\ddot x=F(x)\), \(x(0)=q\), \(\dot x(0)=p\). The above initial value problem generates the map \(T(t):\Sigma \to \Sigma,\quad \Sigma \equiv {\mathbb{R}}^

Advanced Engineering Materials, EarlyView.Herein, environmental scanning electron microscopy (ESEM) is discussed as a powerful extension of conventional SEM for life sciences. By combining high‐resolution imaging with variable pressure and humidity, ESEM allows the analysis of untreated biological materials, supports in situ monitoring of hydration‐driven changes, and advances the functional ...

Advanced Engineering Materials, EarlyView.High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.
