Stochastic Loewner evolution in multiply connected domains [PDF]
, 2004 We construct radial stochastic Loewner evolution in multiply connected domains, choosing the unit disk with concentric circular slits as a family of standard domains.

Constraining the outer boundary condition for the Babcock-Leighton dynamo models
Astronomy & AstrophysicsContext. The evolution of the Sun’s large-scale surface magnetic field is well captured by surface flux transport models, which can therefore provide a natural constraint on the outer boundary condition (BC) of Babcock–Leighton (BL) dynamo models.

Diffusion basis spectrum imaging for identifying pathologies in MS subtypes [PDF]
, 2019 Diffusion basis spectrum imaging (DBSI) combines discrete anisotropic diffusion tensors and the spectrum of isotropic diffusion tensors to model the underlying multiple sclerosis (MS) pathologies. We used clinical MS subtypes as a surrogate of underlying

Design and analysis of a radial diffuser in a single-stage centrifugal pump
Engineering Applications of Computational Fluid Mechanics, 2016 Radial diffusers can improve the flow uniformity in pumps and affect the hydraulic performance of centrifugal pumps directly. The diffusion coefficient d is an important parameter in fluid machinery but it has seldom been used in the diffuser design of ...

Diffusion in neutral and ionized gases with extreme pressure gradients [PDF]
, 1959 Diffusion in vortex flows is considered as a simple case of the more general problem of diffusion in flows with large pressure gradients normal to the principal flow direction. Two examples are considered.

Conformal approach to cylindrical DLA
, 2006 We extend the conformal mapping approach elaborated for the radial Diffusion Limited Aggregation model (DLA) to the cylindrical geometry. We introduce in particular a complex function which allows to grow a cylindrical cluster using as intermediate step ...

A Modified RBF Collocation Method for Solving the Convection-Diffusion Problems
Abstract and Applied Analysis, 2023 The main purposes of this study are to propose the modified radial basis function (RBF) collocation method using a hybrid radial basis function to solve the convection-diffusion problems numerically and to choose the optimal shape parameter of radial ...

Stability of toroidal magnetic fields in stellar interiors
, 2015 We present 3D MHD simulations of purely toroidal and mixed poloidal-toroidal magnetic field configurations to study the behavior of the Tayler instability.

, 2020 In globular clusters, blue straggler stars are heavier than the average star, so dynamical friction strongly affects them. The radial distribution of BSS, normalized to a reference population, appears bimodal in a fraction of Galactic GCs, with a density
