This article reports on the uneven distribution of water molecules of first (D2O-I) and second (D2O-II) types in a D2O-containing beryl crystal grown hydrothermally on a non-singularly oriented fla...

We study min-max affine approximants of a continuous convex or concave function \(f:\Delta \subseteq \mathbb R^k\xrightarrow {} \mathbb R\), where Δ is a convex compact subset of \(\mathbb R^k\). In the case when Δ is a simplex, we prove that there

Comprehensive studies of diamond crystals with a low nitrogen concentration from the placer deposits and kimberlite pipes of Yakutia have facilitated the detection of three titanium-nitrogen-related centers: OK1/S1, N3/440.3 nm and NU1/485 nm in the

Given $\mathcal{X}$ , some measurable subset of Euclidean space, one sometimes wants to construct a finite set of points, $\mathcal{P}\subset\mathcal {X}$ , called a design, with a small energy or discrepancy. Here it is shown that these two measures

Pointwise error estimates for approximation on compact homogeneous manifolds using radial kernels are presented. For a \({\mathcal C}^{2r}\) positive definite kernel κ the pointwise error at x for interpolation by translates of κ goes to 0 like ρr

As is now well known for some basic functions $\phi$, hierarchical and fast multipole-like methods can greatly reduce the storage and operation counts for fitting and evaluating radial basis functions. In particular, for spline functions of the form
