Probabilistic Partitive Partitioning (PPP)

open access: yesCoRR, 2020
Clustering is a NP-hard problem. Thus, no optimal algorithm exists, heuristics are applied to cluster the data. Heuristics can be very resource-intensive, if not applied properly. For substantially large data sets computational efficiencies can be achieved by reducing the input space if a minimal loss of information can be achieved.

Partition algebras

open access: yesEuropean Journal of Combinatorics, 2005
The partition algebras are algebras of diagrams (which contain the group algebra of the symmetric group and the Brauer algebra) such that the multiplication is given by a combinatorial rule and such that the structure constants of the algebra depend polynomially on a parameter.

Reconstruction of Partitions [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2005
For the partition $x=[x_1\ge x_2\ge \cdots\ge x_k]$ of the integer $n=\sum_{i}\, x_{i}$ a $t$-deletion is a partition $y=[y_1\ge y_2\ge \cdots\ge y_k]$ with $x_{i}\geq y_{i}\geq 0$ and $\sum_{i}\, (x_{i}-y_{i})=t$. We prove that all partitions of $n$ are reconstructible from their $t$–deletions if $n$ is sufficiently large in relation to $t$.

Membranolytic Activity of Bile Salts: Influence of Biological Membrane Properties and Composition

open access: yesMolecules, 2007
The two main steps of the membranolytic activity of detergents: 1) the partitioning of detergent molecules in the membrane and 2) the solubilisation of the membrane are systematically investigated.

Multiplicative Partitions [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2013
New formulas for the multiplicative partition function are developed. Besides giving a fast algorithm for generating these partitions, new identities for additive partitions and the Riemann zeta function are also produced.

Remobilization of Dry Matter and Nitrogen in Maize as Affected by Hybrid Maturity Class

open access: yesItalian Journal of Agronomy, 2009
The length of the growing cycle is one of the most important traits determining hybrid adaptability to the environment. The objective of this research was to compare in a field trial the pattern of dry matter and nitrogen accumulation and remobilization ...
