On the Csáki-Vincze transformation

A note on the empty balls left by a critical branching Wiener process Dedicated to Professors Endre Csáki and Pál Révész on the occasion of their 70-th birthday

In this note, we partially confirm some conjectures of P. Révész [10] on the critical branching Wiener process.

On Two-sample Tests Based on Order Statistics

Using Dimension Reduction to Improve the Classification of High-dimensional Data

In this work we show that the classification performance of high-dimensional structural MRI data with only a small set of training examples is improved by the usage of dimension reduction methods. We assessed two different dimension reduction variants: feature selection by ANOVA F-test and feature transformation by PCA. On the reduced datasets, we applied common learning algorithms using 5-fold...

Evidence of pentacene bulk and thin film phase transformation into an orthorhombic phase by iodine diffusion

We present evidence for 130 nm thick pentacene films ordered in the orthorhombic phase obtained by iodine diffusion into the film deposited by classical thermal evaporation. After desorption of iodine by vacuum annealing the crystallographic properties of the investigated pentacene films resemble those of very thin thermal evaporated films that exhibit an orthorhombic phase with high electrical...
