Two additional years of data (2014 and 2015, previous analysis: 2008-13) from the ANTARES neutrino telescope have been analysed using track-like event signatures from the Fermi Bubbles region. Six ...events are found in the signal region with a background expectation of 6.7 leading to more stringent upper limits for the signal flux. A benchmark study indicates that the sensitivity for the Fermi Bubble flux can be boosted when adding the shower channel to the analysis.
This letter presents a combined measurement of the energy spectra of atmospheric νe and νμ in the energy range between ∼100 GeV and ∼50 TeV with the ANTARES neutrino telescope. The analysis uses 3012 ...days of detector livetime in the period 2007–2017, and selects 1016 neutrinos interacting in (or close to) the instrumented volume of the detector, yielding shower-like events (mainly from νe+ν‾e charged current plus all neutrino neutral current interactions) and starting track events (mainly from νμ+ν‾μ charged current interactions). The contamination by atmospheric muons in the final sample is suppressed at the level of a few per mill by different steps in the selection analysis, including a Boosted Decision Tree classifier. The distribution of reconstructed events is unfolded in terms of electron and muon neutrino fluxes. The derived energy spectra are compared with previous measurements that, above 100 GeV, are limited to experiments in polar ice and, for νμ, to Super-Kamiokande.
The Quicksort process R (Rösler (2018)) can be characterized as the unique endogenous solution of the inhomogeneous stochastic fixed point equation R=D(UR1(1∧t∕U)+ {U<t}(1-U)R2((t-U)∕(1-U))+C(U,t))t ...on the space of càdlàg functions, such that R(1) has the Quicksort distribution. In this paper we characterize all -valued solutions of that equation. Every solution can be represented as the convolution of a solution of the inhomogeneous equation and a general solution of the homogeneous equation (Rüschendorf (2006)). The general solutions of the homogeneous equation are the distributions of Cauchy processes Y with constant drift. Any distribution of R+Y for independent R and Y is a solution of the inhomogeneous equation. Every solution of the inhomogeneous equation is of the form R+Y, where R and Y are independent. The endogenous solutions for the inhomogeneous equation are the shifted Quicksort process distributions. In comparison, the Quicksort distribution is the endogenous solution of the Quicksort fixed point equation unique up to a constant (Rösler (1991)). The general solution can be represented as the convolution of the shifted Quicksort distribution and some symmetric Cauchy distribution (Fill and Janson (2000)), possibly degenerate.
The perfect fit of hip stem prostheses is supposed to have positive effects on their lifetime performance. Moreover, the ingrowth of tissue into the surface of the implant has to be assured to create ...a firm and load bearing contact. For the manufacturing of customized hip stem prostheses, the technology of Selective Laser Melting has shown promising results. Poor surface quality, however, makes it necessary to finish up the part by e.g., sand blasting or polishing. With the use of laser ablation for post-processing, reproducible and functionalized surface morphologies might be achievable. Hence, with the motive to produce customized hip stem prostheses, a combined process chain for both mentioned laser technologies is developed. It is examined what type of surface should be produced at which part of the process chain. The produced implants should contain the demanded final surface characteristics without any conventional post-processing. Slight advantages for the Selective Laser Melting regarding the accuracy for different geometrical structures of 400 μm depth were observed. However, an overall improvement of surface quality after the laser ablation process in terms of osseointegration could be achieved. A complete laser based production of customized hip stem implants is found to be with good prospects.
