Validation of Spherical Born Approximation Sensitivity Functions for Measuring Deep Solar Meridional Flow

Author: Vincent Böning
Accurate measurements of deep solar meridional flow are of vital interest for understanding the solar dynamo. In this paper, we validate a recently developed method for obtaining sensitivity functions (kernels) for travel-time mea ... more

SPH Simulations of Abrasive Processes at a Microscopic Scale

Author: Christian Nutto
We present the development of smoothed particle hydrodynamics (SPH) simulations for the investigation of the industrial application of abrasive flow machining (AFM). This process cannot be observed in-situ in experiments and there ... more

Inversions for Deep Solar Meridional Flow Using Spherical Born Kernels

Author: Vincent Böning
The solar meridional flow is a crucial ingredient in modern dynamo theory. Seismic estimates of this flow have, however, been contradictory in deeper layers below about $0.9\,R_\odot$. Results from time-distance helioseismology h ... more

Sensitivity Kernels for Flows in Time-Distance Helioseismology: Extension to Spherical Geometry

Author: Vincent Böning
We extend an existing Born approximation method for calculating the linear sensitivity of helioseismic travel times to flows from Cartesian to spherical geometry. This development is necessary for using the Born approximation for ... more

Evaluation of Pro-Inflammatory Cytokines Expression in Mouse Splenocytes After Co-Incubation with the Biofield Energy Treated Formulation

Author: Viviane J. Elig
With the increasing popularity of herbomineral preparations in healthcare, a new proprietary herbomineral formulation was formulated with ashwagandha root extract and minerals viz. zinc, magnesium, and selenium. The aim of the stu ... more

Metal nanoparticle field-effect transistor

Author: Christian Klinke
We demonstrate that by means of a local top-gate current oscillations can be observed in extended, monolayered films assembled from monodisperse metal nanocrystals - realizing transistor function. The oscillations in this metal-ba ... more
