Open AccessThe energy spectrum of cosmic rays beyond the turn-down around \(\varvec{10^{17}}\) eV as measured with the surface detector of the Pierre Auger Observatory
We present a measurement of the cosmic-ray spectrum above 100 PeV using the part of the surface detector of the Pierre Auger Observatory that has a spacing of 750 m. An inflection of the spectrum is observed, ...

Coorbit Spaces with Voice in a Fréchet Space
We set up a new general coorbit space theory for reproducing representations of a locally compact second countable group G that are not necessarily irreducible nor integrable. Our basic assumption is that the ker...

Reproducing Subgroups of \(Sp(2,\mathbb{R})\) . Part I: Algebraic Classification
We classify the connected Lie subgroups of the symplectic group \(Sp(2,{\mathbb{R}})\) whose elements are matrices in b...

Adaptive Kernel Methods Using the Balancing Principle
The regularization parameter choice is a fundamental problem in Learning Theory since the performance of most supervised algorithms crucially depends on the choice of one or more of such parameters. In particu...

Optimal Rates for the Regularized Least-Squares Algorithm
We develop a theoretical analysis of the performance of the regularized least-square algorithm on a reproducing kernel Hilbert space in the supervised learning setting. The presented results hold in the genera...

Model Selection for Regularized Least-Squares Algorithm in Learning Theory
We investigate the problem of model selection for learning algorithms depending on a continuous parameter. We propose a model selection procedure based on a worst-case analysis and on a data-independent choice...

Epidemiology of hepatitis C virus antibodies in blood donors from the province of Latina, Italy
In order to calculate the incidence of hepatitis C virus (HCV) antibodies in blood donors and to verify the efficacy of the pre-donation method (testing blood samples of potential donors at least 3 months in a...

A Theorem of Ludwig Revisited
Using a recent result of Busch and Gudder, we reconsider a theorem of Ludwig which allows one to identify a class of effect automorphisms as the symmetry transformations in quantum mechanics.

Electrophoretic Analytical Technique for the Genetic Identification of Mycorrhizal Fungi of the Genus Tuber and Their Mycelium and Mycorrhiza
Truffles are ectomycorrhizic hypogean fungi of the Ascomycotina (Order Tuberales). They are particularly known for their edible fruitbodies (ascocarps) where the reproductive structures are localized. The life...

Disc electrophoresis of proteins in the presence of sodium dodecyl sulphate
Die elektrophoretische Trennungsmethode an Polyacrilamidgelen vonOrnstein undDavis 4 wurde so abgeändert, dass sie im Anwesenheit von Natrium-dodecyl-sulfat zu gebrauchen ist. Dadurch ist es möglich, Assoziatione...
