AB - This paper reveals the 3D character of the intermetallic layer at the aluminum–steel interface which pops
up above the original sample surface during annealing. Popping out of the intermetallics was proven using
atomic force microscopy. The phase expands out of the plane due to the exothermic formation of the Al5Fe2
phase and the feasibility of surface diffusion. Milling by a focused ion beam enabled the comparison of the
chemical composition of the surface layer with the bulk interface, showing no difference. The growth direction
is both towards aluminum and steel — the main diffusion flux is from aluminum towards steel, and the new
intermetallic phase emerges at the steel side. The shortage of Al atoms causes a shift of the intermetallic as a
whole towards aluminum.

AB - Abstract. In the numerical simulation of mechanical joining technologies such as clinching, the material modeling of the joining parts is of major importance. This includes modeling the damage and failure behavior of the materials in accordance with varying occurring stress states. This paper presents a calibration method of three different fracture models. The calibration of the models is done by use of experimental data from a modified punch test, tensile test and bulge test in order to map the occurring stress states from clinching processes and to precisely model the resulting failure behavior. Experimental investigations were carried out for an aluminum alloy EN AW-6014 in temper T4 and compared with the simulative results generated in LS-DYNA. The comparison of force-displacement curves and failure initiation shows that the Hosford–Coulomb model predicts the failure behavior for the material used and the tests applied with the best accuracy.

AB - Abstract
Purpose
Wearables serve to quantify the on-court activity in intermittent sports such as field hockey (FH). Based on objective data, benchmarks can be determined to tailor training intensity and volume. Next to average and accumulated values, the most intense periods (MIPs) during competitive FH matches are of special interest, since these quantify the peak intensities players experience throughout the intermittent matches. The aim of this study was to retrospectively compare peak intensities between training and competition sessions in a male FH team competing in the first german division.
Methods
Throughout an 8-week in-season period, 372 individual activity datasets (144 datasets from competitive sessions) were recorded using the Polar Team Pro sensor (Kempele, Finland). MIPs were calculated applying a rolling window approach with predefined window length (1–5 min) and calculated for Total distance, High-Intensity-Running distance (> 16 km/h), Sprinting distance (> 20 km/h) and Acceleration load. Significant differences between training and competition MIPs were analysed through non-parametric statistical tests (P < 0.05).
Results
Analyses revealed higher MIPs during competition for all considered outcomes (P < 0.001). Effect size estimation revealed strongest effects for sprinting distance (d = 1.89 to d = 1.22) and lowest effect sizes for acceleration load (d = 0.92 to d = 0.49).
Conclusion
The present findings demonstrate that peak intensities during training do not reach those experienced during competitive sessions in a male FH team. Training routines such as manipulations of court-dimensions and team sizes might contribute to this discrepancy. Coaches should compare training and competition intensities to recalibrate training routines to optimize athletes’ preparation for competition.

AB - This preprint makes the claim of having computed the $9^{th}$ Dedekind
Number. This was done by building an efficient FPGA Accelerator for the core
operation of the process, and parallelizing it on the Noctua 2 Supercluster at
Paderborn University. The resulting value is
286386577668298411128469151667598498812366. This value can be verified in two
steps. We have made the data file containing the 490M results available, each
of which can be verified separately on CPU, and the whole file sums to our
proposed value.
