Microtexturing of implant surfaces is of major relevance in the endeavor to improve biorelevant implant designs. In order to elucidate the role of biomaterial’s topography on cell physiology, obtaining quantitative correlations between cellular beh

A set $$\mathcal {S}$$ S of points in $$\mathbb {R}^n$$ R n is called a rationally parameterizable hypersurface if there is vector function $$\varvec{\sigma }:\mathbb {R}^{n-1}\rightarrow \mathbb {R}^n$$ σ : R n - 1 → R n having as components rati

A set $A \subseteq {\mathbb{R}}^n$ is called an antichain (resp. antichain) if it does not contain two distinct elements ${\mathbf x}=(x_1,\ldots, x_n)$ and ${\mathbf y}=(y_1,\ldots, y_n)$ satisfying $x_i\le y_i$ (resp. $x_i < y_i$) for all $i\in \{1

The starting point of this book is Sperner's theorem, which answers the question: What is the maximum possible size of a family of pairwise (with respect to inclusion) subsets of a finite set? This theorem stimulated the development of a fast growing

The signal contribution function (SCF) was introduced by Gemperline in 1999 and Tauler in 2001 in order to study band boundaries of multivariate curve resolution (MCR) methods. In 2010 Rajkó pointed out that the extremal profiles of the SCF reproduc

Let 𝒫 {\mathcal{P}} be an n-dimensional convex polytope and let 𝒮 {\mathcal{S}} be a hypersurface in ℝ n {\mathbb{R}^{n}} . This paper investigates potentials to reconstruct 𝒫 {\mathcal{P}} , or at least to compute significant properties o

Let $\mathcal{P}$ and $\mathcal{P}'$ be $3$-dimensional convex polytopes in $\mathbb{R}^3$ and $S \subseteq \mathbb{R}^3$ be a non-empty intersection of an open set with a sphere. As a consequence of a somewhat more general result it is proved that $

A new recursive algorithm for the least squares problem subject to linear equality and inequality constraints is presented. It is applicable for problems with a large number of inequalities. The algorithm combines three types of recursion: time-, ord

Let n and m be integers, n > m ≥ 2 , and let A = { A 1 , … , A m } be a partition of [ n ] , where [ n ] = { 1 , … , n } . For a subset X of [ n ] , its A -boundary region A ( X ) is defined to be the union of those blocks A i of A for which A
