The 3D Visibility of Rust: Micro Computed Tomography Investigations of a Roman Iron Nail from Aguntum Open
The restoration of iron finds is still a particularly complex area within the science of archaeological conservation, as severe signs of corrosion occur from the moment of recovery and the associated radical change in environmental paramet…

Analysis of the effect of impact loadings on the gas permeability properties of CF-PA6 composites Open
This study investigates the damage-dependent permeability properties of polyamide 6 based carbon fiber-reinforced thermoplastic composites (CF-PA6) by analyzing the gas permeability differences before and after low-velocity impact loading.…

Free positive multiplicative Brownian motion and the free additive convolution of semicircle and uniform distribution Open
The free positive multiplicative Brownian motion $(h_t)_{t\geq0}$ is the large $N$ limit in non-commutative distribution of matrix geometric Brownian motion. It can be constructed by setting $h_t:=g_{t/2}g_{t/2}^*$, where $(g_t)_{t\geq0}$ …

Mineralogical and Micro-Computer Tomographic (μCT) Texture Investigations of Egyptian Blue Spheres (Aguntum, East Tyrol; Retznei and Wagna, Flavia Solva, South Styria) Open
Egyptian Blue was the first synthetic pigment by humankind. It contains of cuprorivaite, which is a calcium-copper-silicate (CaCuSi4O10). This study reports the results of a mineralogical and computer tomographic study of Egyptian Blue fin…

An explicit formula for free multiplicative Brownian motions via spherical functions Open
After some normalization, the logarithms of the ordered singular values of Brownian motions on $GL(N,\mathbb F)$ with $\mathbb F=\mathbb R, \mathbb C$ form Weyl-group invariant Heckman-Opdam processes on $\mathbb R^N$ of type $A_{N-1}$. We…

Roman urban landscape Open
A book presents new elements of the urbanistic aspects of Roman towns and minor settlements in the large area of Caput Adriae, Noricum, and Pannoniae. The result of these efforts is twenty-six contributions by 54 authors from eight countri…

Wigner- and Marchenko-Pastur-type limits for Jacobi processes Open
We study Jacobi processes $(X_{t})_{t\ge0}$ on the compact spaces $[-1,1]^N$ and on the noncompact spaces $[1,\infty[^N$ which are motivated by the Heckman-Opdam theory for the root systems of type BC and associated integrable particle sys…

Open Lake Phosphorus Forcing of Cladophora Growth: Modeling the Dual Challenge in Great Lakes Trophic State Management Open
Stimulated by excess levels of phosphorus, the attached, filamentous green alga Cladophora grows to nuisance proportions in Lake Michigan, one of the Laurentian Great Lakes. While nearshore waters impacted by local sources of the nutrient …

Management of the Phosphorus–Cladophora Dynamic at a Site on Lake Ontario Using a Multi-Module Bioavailable P Model Open
The filamentous green alga Cladophora grows to nuisance proportions in Lake Ontario. Stimulated by high phosphorus concentrations, nuisance growth results in the degradation of beaches and clogging of industrial water intakes with attendan…

How to teach an old dog new tricks: a new approach on dating unstratified archaeological features from outdated excavations Open
When analysing past excavations, the possible lack of information on stratigraphy of small finds can lead to difficulties in dating features of settlements such as building periods or destruction layers. While there can be many factors, th…

Management Transition to the Great Lakes Nearshore: Insights from Hydrodynamic Modeling Open
The emerging shift in Great Lakes management from offshore to nearshore waters will require attention to complexities of coastal hydrodynamics and biogeochemical transformations. Emphasizing hydrodynamics, this work resolves transport proc…
