Comparison of synthetic maps from truncated jet-formation models with YSO jet observations [PDF]
(abridged) Significant progress has been made in the last years in the understanding of the jet formation mechanism through a combination of numerical simulations and analytical MHD models for outflows characterized by the symmetry of self-similarity. In

Self-propelled non-linearly diffusing particles. Aggregation and continuum description [PDF]
We introduce a model of self-propelled particles carrying out a Brownian motion with a diffusion coefficient which depends on the local density of particles within a certain finite radius. Numerical simulations show that in a range of parameters the long-

On a Numerical Radius Preserving Onto Isometry on L(X)
We study a numerical radius preserving onto isometry on L(X). As a main result, when X is a complex Banach space having both uniform smoothness and uniform convexity, we show that an onto isometry T on L(X) is numerical radius preserving if and only if ...

The Ising model with long-range interactions
The phase transition in the two-dimensional and three-dimensional Ising models with long-range spin interactions are studied with the Monte-Carlo method. The interaction region between spins is characterized by the radius $R$.

New Analytical Formula for Supercritical Accretion Flows [PDF]
We examine a new family of global analytic solutions for optically thick accretion disks, which includes the supercritical accretion regime. We found that the ratio of the advection cooling rate, $Q_{\rm adv}$, to the viscous heating rate, $Q_{\rm vis}$,

Schur product of matrices and numerical radius (range) preserving maps
Let \(M_n\) (resp., \(H_n)\) be the algebra of \(n\)-by-\(n\) complex matrices (resp., Hermitian matrices). The numerical range \(W(A)\) and numerical radius \(w(A)\) of \(A\) in \(M_n\) are given by \[ W(A)=\{x^*Ax: x\in\mathbb{C}^n,x^*x=1\}\quad\text{and} \quad w(A)=\max\{|\lambda|: \lambda\in W(A)\}, \] respectively.

Flow interference of two side-by-side square cylinders using IB-LBM – Effect of corner radius
In this study, a two-dimensional Immersed Boundary Lattice Boltzmann Method (IB-LBM) is employed to investigate computationally effect of flow past a pair of square cylinders in side-by-side arrangement at Re=100, for various corner radii.
